Resource format indicators in bandwidth part management for full-duplex resource allocation

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may communicate with a base station using an operating bandwidth part (BWP) that includes a first set of frequency resources. The UE may receive a group-common downlink control information (GC-DCI) message from the base station that includes a resource format indicator (RFI) for the UE (e.g., among multiple RFIs for a set of UEs in the GC-DCI) indicating a second set of frequency resources. The UE may modify the operating BWP based on the second set of frequency resources and communicate with the base station using the modified operating BWP. In some examples, the UE may switch the operating BWP to the second set of frequency resources or may reduce the operating BWP to a set of overlapping frequency resources between the first and second sets of frequency resources.

FIELD OF TECHNOLOGY

The following relates to wireless communications, including resource format indicators (RFIs) in bandwidth part (BWP) management for full-duplex resource allocation.

BACKGROUND

Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time-division multiple access (TDMA), frequency-division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency-division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as user equipment (UE).

In some wireless communications systems, a UE may receive signaling to indicate whether resources for a time period are configured for uplink communications or downlink communications. For example, a slot format indicator (SFI) may indicate that a first slot is allocated for uplink transmissions from the UE to a base station, and a second slot is allocated for downlink transmissions from the base station to the UE. However, conventional signaling may be limited capability and flexibility for alternative resource format types.

For example, a UE may communicate with a base station using an active set of frequency resources, which may be referred to as a bandwidth part (BWP). The BWP may span a set of frequency resources in a specific carrier. In some examples, the UE may be configured with multiple BWPs (e.g., one or more uplink BWPs, one or more downlink BWPs, or a combination thereof), where an uplink BWP and a downlink BWP may be active for the UE at a given time. The UE may communicate data, control information, feedback information, or any combination thereof within the active BWPs. In some cases, a base station may allocate a set of frequency resources to the UE for communication. However, the allocated set of frequency resources may fail to correspond to an active BWP for the UE, which may result in inconsistent operation between the UE and the base station, potentially degrading system performance.

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support resource format indicators (RFIs) in bandwidth part (BWP) management for full-duplex resource allocation. Generally, the described techniques provide for signaling resource allocations for full-duplex slots. For example, a user equipment (UE) may receive a configuration for interpreting RFIs indicating resource formats (e.g., uplink format, downlink format, full-duplex format) for time periods (e.g., slots) of communication resources allocated to the UE. The UE may additionally receive a control message including an RFI for one or more time periods. Based on the configuration and the RFI, the UE may determine a resource format (e.g., uplink format, downlink format, and full-duplex format) for each time period, and may further determine a frequency resource allocation for each time period including symbols having a full-duplex format.

The described techniques may also provide for improving frequency resource allocation by dynamically updating an operating bandwidth part (BWP) based on frequency resources indicated in a group-common downlink control information (GC-DCI) message. One or more UEs may communicate with a base station as part of a wireless communications system. A UE of the one or more UEs may communicate according to an operating BWP (e.g., an active uplink BWP and an active downlink BWP) that includes a first set of frequency resources. The UEs may receive a GC-DCI message that includes an RFI indicating a second set of frequency resources for the UE for communications in one or more specified slots. However, the second set of frequency resources may not fully overlap with the first set of frequency resources of the operating BWP. The UE may modify the operating BWP based on the second set of frequency resources to determine modified frequency resources for communication.

In some examples, modifying the operating BWP may involve switching the operating BWP to the second set of frequency resources indicated by the RFI. In some other examples, modifying the operating BWP may involve reducing the operating BWP to a set of overlapping frequency resources based on an overlap between the first set of frequency resources and the second set of frequency resources (e.g., without performing a BWP switching operation). By modifying the operating BWP, the UE may support dynamic configuration by a base station for communicating in a slot allocated for downlink and uplink communications.

DETAILED DESCRIPTION

In some wireless communications systems, a user equipment (UE) may receive a resource format indicator (RFI), such as a slot format indicator (SFI). The RFI (e.g., SFI) may indicate a resource format (e.g., uplink format or downlink format) associated with slots allocated for communications at the UE. For example, an SFI may indicate that a first slot is allocated for uplink transmissions from the UE to a base station, and a second slot is allocated for downlink transmissions from the base station to the UE. In some wireless communications, every symbol and/or every frequency resource within a given slot may be configured for the same resource format (e.g., uplink or downlink or flexible). Some UEs may be configured to perform communications using symbols having a full-duplex format (e.g., symbols which include resources for both uplink and downlink communications). However, conventional wireless communications systems operating in time-division duplexing (TDD) may not support signaling which indicates slots including symbols having a full-duplex format within the component carrier bandwidth. Moreover, conventional wireless communications systems may not support signaling frequency resource allocations for symbols having a full-duplex format.

To address the deficiencies associated with conventional resource format signaling, techniques described herein are directed to signaling resource allocations for full-duplex slots. For example, a UE may receive a configuration (e.g., configuration signaling indicating indexes or tables) for interpreting RFIs (e.g., SFIs) indicating resource formats for time periods (e.g., slots) of communication resources allocated to the UE. The resource formats may include an uplink format, a downlink format, a flexible format, or a full-duplex format. In some aspects, configurations for interpreting RFIs which are received and identified by the UE may cause different UEs to interpret the same RFI differently. For example, an RFI indicating an index of “1” may be interpreted differently by a first UE and a second UE depending on their respective configurations.

Subsequently, a UE may additionally receive a control message including an RFI (e.g., SFI) for one or more time periods (e.g., slots). Based on the configuration and the RFI, the UE may determine a resource format (e.g., uplink format, downlink format, and full-duplex format) for each time period, and may further determine a frequency resource allocation for each time period including symbols having a full-duplex format. In some aspects, both resource formats and frequency resource allocations for slots having a full-duplex format may be indicated separately within different portions (e.g., different bits) of the RFI. In additional or alternative aspects, resource formats may be indicated via the RFI, while frequency resource allocations for slots having a full-duplex format may be indicated in a separate, designated portion/field (e.g., reserved portion) of the control message which is reserved for indicating frequency resource allocations. Furthermore, in some aspects, a combined or jointly coded configuration for interpreting RFIs may include both a time resource allocation scheme and a frequency resource allocation scheme. In such cases, a UE may utilize the combined configuration to determine both resource formats and frequency resource allocations from a storage object indicated via an RFI (e.g., SFI storage object indicates both resource format and frequency resource allocation).

In some examples, a UE may be configured to operate in accordance with a full-duplex mode or a full-duplex aware mode. The UE may be configured with a set of frequency resources for communicating with a base station. The set of frequency resources may be referred to as an operating bandwidth part (BWP) and may include an active uplink BWP, an active downlink BWP, or both. In some examples, the UE may receive an RFI, such as an SFI. The RFI may indicate a number of resource formats for a set of slots (e.g., an uplink format, a downlink format, a flexible format, a full-duplex format, or any combination of these or other slot formats) and a set of frequency resources (e.g., a slot frequency format, a BWP pair, a BWP and a corresponding resource bandwidth (RBW), or any other indication of frequency resources) for flexibly configuring the UE. However, the set of frequency resources indicated for communications at the UE may not fully overlap with the configured active BWPs of the UE, which may degrade the UE's performance.

Various aspects of the present disclosure provide techniques for a UE to communicate with a base station in the context of full-duplex operation or full-duplex aware operation. For example, a UE may be configured with an operating BWP (e.g., an active pair of uplink and downlink BWPs) that includes a first set of frequency resources (e.g., including uplink and downlink frequency resources), and the UE may communicate with a base station using the operating BWP. The UE may receive a group-common downlink control information (GC-DCI) message from the base station that includes an RFI (e.g., an SFI) indicating a second set of frequency resources. The GC-DCI message may be an example of a control message including control information for a group of UEs, where each UE receiving the GC-DCI message may identify a subset of the control information relevant to that specific UE. The UE determining the indicated second set of frequency resources may modify the operating BWP based on the second set of frequency resources and may communicate with the base station using the modified operating BWP.

In some examples, modifying the operating BWP based on a set of frequency resources indicated in a downlink message (e.g., the second set of frequency resources) may involve a BWP switch or a BWP reduction. In some cases, the UE may modify the operating BWP by switching the operating BWP to the set of frequency resources indicated in the downlink message. In some other cases, the UE may modify the operating BWP by reducing the operating BWP to a set of frequency resources that overlaps between the first set of frequency resources (e.g., the UE's operating BWP) and the second set of frequency resources (e.g., the frequency resources indicated in the GC-DCI message). In some examples, the UE may support full-duplex operation and communicate with the base station using the modified operating BWP in a full-duplex mode, while in some additional or alternative examples, the UE may support full-duplex aware operation and may communicate with the base station using the modified operating BWP in a half-duplex mode. The second set of frequency resources (e.g., the set of frequency resources indicated by the downlink message) may be indicated via a slot frequency format, a BWP pair, or a BWP and an RBW for the BWP.

In some cases, the UE may modify the operating BWP based on a frequency resource table. For example, the UE may be pre-configured with a frequency resource table, or the UE may generate the frequency resource table based on a configuration procedure (e.g., a radio resource control (RRC) configuration procedure). The set of frequency resources indicated in the downlink message may correspond to the frequency resource table, and the UE may modify the operating BWP based on the frequency resources indicated in the downlink message and the frequency resource table. Modifying an operating BWP based on a set of frequency resources indicated in a downlink message (e.g., a GC-DCI message) may improve system efficiency and decrease signaling latency, for example, by supporting full-duplex operation in full-duplex formatted symbols.

Aspects of the disclosure are initially described in the context of wireless communications systems, resource allocation schemes, and process flows. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to RFIs in BWP management for full-duplex resource allocation.

The UEs115and the base stations105of the wireless communications system100may support communications for signaling resource allocations for full-duplex slots allocated for communications at a UE115. In particular, a UE115may receive, from a base station105, a configuration for interpreting RFIs indicating resource formats (e.g., uplink format, downlink format, flexible format, full-duplex format) for time periods (e.g., slots) of communication resources allocated to the UE115. The base station105may indicate the configuration for interpreting RFIs via RRC signaling, control messages, configuration messages, or any combination thereof. The UE115may additionally receive a control message (e.g., a downlink control information (DCI) message) from the base station105, where the control message includes an RFI for one or more time periods. Based on the configuration and the RFI, the UE115may determine a resource format (e.g., uplink format, downlink format, flexible format, and full-duplex format) for each time period, and may further determine a frequency resource allocation for each time period including symbols having a full-duplex format.

For the purposes of the present disclosure, the term “time periods” may be used to refer to any period of time resources allocated for wireless communications. In this regard, the term “time period” may be used interchangeably with the term “slot.” However this is not to be regarded as a limitation of the present disclosure. Moreover, the term “RFIs” may refer to any indication, index, table, or storage object which is used to indicate resource formats (e.g., uplink format, downlink format, flexible format, full-duplex format) for slots of resources allocated to a UE115. In this regard, an RFI may include, but is not limited to, an SFI.

By way of example, a base station105may transmit a downlink transmission including an indication of a configuration for interpreting RFIs allocated to the UE115. In some aspects, configurations for interpreting RFIs which are received and identified by UEs115may cause different UEs115to interpret the same RFI differently. For example, an RFI indicating an index of “1” may be interpreted differently by a first UE115and a second UE115depending on their respective configurations. For instance, the first UE115may interpret the index of “1” as indicating an uplink resource format, whereas the second UE115may interpret the index of “1” as indicating a full-duplex resource format.

Continuing with the same example, the UE115may additionally receive a control message (e.g., DCI, GC-DCI) including an RFI for a set of slots allocated to the UE115. Based on the configuration and the RFI, the UE115may determine a resource format (e.g., uplink format, downlink format, and full-duplex format) for each slot, and may further determine a frequency resource allocation for each slot including symbols having a full-duplex format. In some aspects, the RFIs may be indicated in GC-DCI, thereby enabling each respective UE115to interpret the same GC-DCI according to the respective configuration associated with the UE115.

In some aspects, both resource formats and frequency resource allocations for slots having a full-duplex format may be indicated within different portions (e.g., different bits) of the RFI. In additional or alternative aspects, resource formats may be indicated in the RFI, while frequency resource allocations for slots having a full-duplex format may be indicated in a separate, designated (e.g., reserved) portion of the control message which is reserved for indicating frequency resource allocations. Furthermore, in some aspects, a combined configuration for interpreting RFIs may include both a time resource allocation scheme and a frequency resource allocation scheme. In such cases, a UE115may utilize the combined configuration to determine both resource formats and frequency resource allocations from a storage object indicated via an RFI (e.g., SFI storage object indicates both resource format and frequency resource allocation).

As an example, a UE115may communicate with a base station105over a first set of frequency resources, which may be referred to as a BWP or an operating BWP. For example, the UE's operating BWP may be a set of frequency resources allocated for communications to or from the UE115according to a radio access technology (RAT), such as NR, LTE, or any other RAT. The BWP may span a set of contiguous or non-contiguous frequency resources in a specific carrier. In some examples, the UE115may be configured with multiple BWPs (e.g., one or more uplink BWPs, one or more downlink BWPs, or a combination thereof), where an uplink BWP and a downlink BWP may be active for the UE115at a given time. The UE115may communicate data, control information, feedback information, or any combination thereof within the active BWPs.

The UE115may receive, from a base station105, a GC-DCI message. For example, the base station105may transmit (e.g., broadcast) the GC-DCI message to multiple UEs115in a coverage area110. The GC-DCI message may be an example of any DCI message transmitted to multiple recipients. The message may include control information for multiple UEs115, such that a UE115receiving the GC-DCI message may determine a portion of the control information intended for the UE115. For example, the UE115may identify an RFI included in the GC-DCI message that indicates a second set of frequency resources. In some cases, the second set of frequency resources may not fully overlap with the first set of frequency resources (e.g., a current operating BWP for the UE115). However, the wireless communications system100may support the UE115modifying the operating BWP based on the second set of frequency resources.

For example, a UE115may communicate with a base station105using an operating BWP (e.g., including an active uplink BWP and an active downlink BWP) that includes a first set of frequency resources in a carrier bandwidth. The UE115may receive a GC-DCI message that includes an RFI indicating a second set of frequency resources for the UE115. The UE115may modify the operating BWP based on the second set of frequency resources. Modifying the operating BWP may include switching the operating BWP to the second set of frequency resources indicated by the RFI or reducing the operating BWP to a set of overlapping frequency resources based on an overlap between the first set of frequency resources and the second set of frequency resources. The UE115may communicate with the base station105according to the modified operating BWP (e.g., in a slot allocated for downlink and uplink communications).

The techniques described herein may provide for more flexible resource allocations. In particular, techniques described herein may support signaling for full-duplex formats, as well as signaling for frequency resource allocations associated with time periods including symbols having a full-duplex format. Moreover, by sending a single GC-DCI transmission to a group of UEs115which indicates RFIs (e.g., SFIs), base stations105may decrease the control signaling used to communicate RFIs, thereby reducing resource and messaging overhead within the wireless communications system100.

FIG.2illustrates an example of a wireless communications system200that supports RFIs in BWP management for full-duplex resource allocation in accordance with aspects of the present disclosure. In some examples, wireless communications system200may implement aspects of wireless communications system100. The wireless communications system200may include a UE115-aand a base station105-a, which may be examples of UEs115and base stations105, as described with reference toFIG.1.

The UE115-amay communicate with the base station105-ausing a communication link205. In some cases, the communication link205may include an example of an access link (e.g., a Uu link). The communication link205may include a bi-directional link that can include both uplink and downlink communication. For example, the UE115-amay transmit uplink transmissions220, such as uplink control signals or uplink data signals, to the base station105-ausing the communication link205, and the base station105-amay transmit downlink transmissions, such as downlink control signals or downlink data signals, to the UE115-ausing the communication link205.

The UE115-aand the base station105-aof the wireless communications system200may support communications for signaling resource allocations for full-duplex slots allocated for communications at a UE115-a. In particular, the UE115-amay receive, from the base station105-a, a configuration (e.g., index, table) for interpreting RFIs indicating resource formats (e.g., uplink format, downlink format, flexible format, full-duplex format) for time periods (e.g., slots) of communication resources allocated to the UE115-a. The UE115-amay additionally receive a control message (e.g., DCI, GC-DCI) from the base station105, where the control message includes an RFI for one or more time periods. Based on the configuration and the RFI, the UE115-amay determine a resource format (e.g., uplink format, downlink format, and full-duplex format) for each time period, and may further determine a frequency resource allocation for each time period including symbols having a full-duplex format. The UE115-amay then transmit uplink transmissions220to the base station105-abased on the determined resource formats, the determined frequency resource allocations, or both.

For example, the base station105-amay transmit an RRC message210including an indication of a configuration for interpreting RFIs (e.g., SFIs) associated with the UE115-a. The RFIs may indicate one or more resource formats associated with one or more time periods (e.g., slots) of communication resources allocated to the UE115-a. For example, the one or more resource formats indicated by the RFIs may include a downlink format, an uplink format, or a full-duplex format. In some cases, the base station105-amay transmit the RRC message210including the indication of the configuration based on a capability of the UE115-ato recognize the full-duplex format.

In additional or alternative aspects, the configuration for interpreting RFIs indicated in the RRC message210may include a time resource allocation scheme and a frequency resource allocation scheme. In this regard, the configuration indicated to the UE115-amay include a configuration for interpreting both resource formats and frequency resource allocations based on values or storage objects indicated in RFIs. In this regard, the configuration for interpreting RFIs may include a joint-configuration which is used to determine both time and frequency resources.

In some aspects, the UE115-amay identify the configuration for interpreting RFIs. In some aspects, the UE115-amay identify the configuration for interpreting RFIs based on receiving the RRC message210from the base station105-a. Additionally or alternatively, the UE115-amay be preconfigured with the configuration for interpreting RFIs, and may thereby identify the configuration for interpreting RFIs without receiving the RRC message210. In some aspects, the UE115-amay identify the configuration for interpreting RFIs based on a capability of the UE115-ato recognize full-duplex formats.

In some aspects, the UE115-amay identify one or more configurations for interpreting RFIs. In particular, RFIs which indicate varying quantities of slots including symbols having a full-duplex format may be associated with different configurations. For example, in some cases, the UE115-bmay identify a first configuration associated with RFIs indicating a single time period (e.g., single slot) including a set of symbols having a full-duplex format, and may identify a second configuration associated with RFIs indicating a two or more time periods (e.g., single slot) including a set of symbols having a full-duplex format.

In some aspects, the UE115-amay receive a control message215from the base station105-a. The control message215may include an RFI (e.g., SFI) for one or more time periods (e.g., slots) of communication resources allocated to the UE115-a. The control message215may include DCI, GC-DCI, or the like. For example, the control message may include an enhanced DCI (e.g., DCI 2_0, DCI 2_x) which is used to indicate both resource formats (e.g., uplink format, downlink format, full-duplex format) as well as frequency resource allocations for slots including symbols having a full-duplex format. In some aspects, at least one time period (e.g., at least one slot) of the one or more time periods allocated to the UE115-aindicated via the control message215may include a time period (e.g., slot) including symbols having a full-duplex format.

As noted previously herein, not all UEs115may be compatible with full-duplex communications. Accordingly, in some aspects, UEs115which are not configured for full-duplex communications may only receive and monitor for “legacy” control messages (e.g., DCI 2_0) which do not indicate full-duplex slots and/or frequency resource allocations for full-duplex slots, and UEs115which are configured for full-duplex communications may receive and monitor for both “legacy” control messages (e.g., DCI 2_0) as well as “enhanced” control messages (e.g., enhanced DCI 2_0, DCI 2_x) which indicate full-duplex slots and/or frequency resource allocations for full-duplex slots. In this regard, the UE115-amay receive the control message215based on a capability of the UE115-ato recognize full-duplex formats. Additionally or alternatively, UEs115which are not configured for full-duplex communications may receive enhanced control messages, where resources associated with the UEs115within the enhanced control messages may not include indications of full-duplex slots and/or frequency resource allocations for full-duplex slots.

In some cases, UEs115which are configured to recognize and communicate with full-duplex slots may be referred to as “full-duplex UEs.” Comparatively, UEs115which are configured to recognize full-duplex slots but are not configured to communicate with full-duplex slots may be referred to as “full-duplex-aware UEs,” while UEs115which are not configured to recognize or communicate with full-duplex slots may be referred to as “non-full-duplex-aware UEs.”

It is further noted herein that configuring each UE115with configurations for interpreting RFIs separately may allow for UEs115of varying complexity or sophistication (e.g., UEs115which are and/or are not configured for full-duplex communications) to receive and interpret common control messages (e.g., enhanced control messages) and common RFIs. For example, some UEs115may not be capable of recognizing full-duplex formats (e.g., non-full-duplex-aware UEs), and may be unable to perform communications via full-duplex formats. However, by separately configuring UEs115to interpret control messages215and/or RFIs, both UEs115which are configured for full-duplex communications (e.g., full-duplex UEs) and UEs115which are not configured for full-duplex communications (e.g., full-duplex-aware UEs, non-full-duplex aware UEs) may be able to receive and interpret the same control message215and/or the same RFIs. For example, the UE115-amay be configured (e.g., capable) for full-duplex communications (e.g., full-duplex UE), while a second UE115may not be configured (e.g., not capable) for full-duplex communications (e.g., full-duplex-aware UE). In this example, the UE115-amay be configured to interpret an RFI of “1” as indicating a slot with a full-duplex format, while the second UE115may be configured to interpret the RFI of “1” as indicating a slot with an uplink format.

In some aspects, the UE115-amay identify one or more indexes associated with the UE115-a. The one or more indexes may include indications for the UE115-ato monitor certain portions of the control message215which are associated with the UE115-a. In some aspects, the UE115-amay identify the one or more indexes based on the RRC message210, the control message215, other signaling from the base station105-a, or any combination thereof. Moreover, the UE115-amay identify the one or more indexes based on a capability of the UE115-ato recognize full-duplex formats.

For example, the first few slots or bits of the control message215may include one or more indexes indicating portions of the control message215that the UE115-ais to monitor to determine resource allocations. For instance, the UE115-amay identify, within the control message215, an index associated with the UE115-a, where the index indicates a position of an RFI associated with the UE115-awithin the control message215.

In some aspects, the UE115-amay identify a single index which indicates for the UE115-ato monitor one or more portions of the control message215. Additionally or alternatively, the UE115-amay identify multiple indexes which indicate for the UE115-ato monitor multiple portions of the control message215. For example, in some cases, the UE115-amay identify a first index within the control message215, where the first index indicates for the UE115-ato monitor a first portion of the control message215. Continuing with the same example, the UE115-amay identify a second index within the control message215, where the second index indicates for the UE115-ato monitor a second portion of the control message215which is different from the first portion. For instance, the first portion of the control message215indicated by the first index may include an RFI, and the second portion of the control message indicated by the second index may include a portion of the control message215which is reserved for indications of frequency resource allocations for the RFIs included within the control message215.

In some aspects, the UE115-amay identify an index associated with one or more component carriers associated with the UE115-a. For example, the UE115-amay identify an index for each component carrier of a set of component carriers associated with the UE115-a. In this example, each index may indicate a position of an RFI within the control message215which is associated with each respective component carrier. In this regard, resource formats and/or frequency resource allocations for full-duplex slots may be indicated separately for each respective component carrier of the UE115-a.

Additionally or alternatively, the UE115-amay identity an index for a first component carrier associated with the UE115-a, where the index for the first component carrier indicates a position of an RFI within the control message215which is associated with one or more component carriers associated with the UE115-a. For example, the RFI may be associated with every component carrier associated with the UE115-a. In this regard, an index and/or RFI associated with one component carrier of the UE115-amay be used for additional component carriers of the UE115-a.

The UE115-amay monitor the control message215, or portions of the control message215, based on the one or more identified indexes. For example, in cases where the UE115-aidentifies a single index indicating a position of an RFI within the control message215, the UE115-amay monitor the portion of the control message215including the RFI based on identifying the index. By way of another example, in cases where the UE115-aidentifies a first index indicating a position of an RFI within the control message215, and a second index indicating a portion of the control message215reserved for indications of frequency resource allocations, the UE115-amay monitor portions of the control message215including the RFI and the portion of the control message215reserved for indications of frequency resource allocations.

In some aspects, the UE115-amay determine a resource format (e.g., uplink format, downlink format, full-duplex format) for each time period (e.g., each slot) of communication resources allocated to the UE115-a. Moreover, the UE115-amay determine a resource format for each time period of communication resources allocated to the UE115-aassociated with each component carrier associated with the UE115-a. In this regard, the UE115-amay determine resource formats for each component carrier associated with the UE115-a. In some aspects, the UE115-amay determine the resource formats based on the RRC message210, the configuration for interpreting RFIs, the control message215including the RFI, or any combination thereof. For example, the UE115-amay determine a resource format for each time period based on at least a portion of the RFI within the control message215.

The UE115-amay additionally identify one or more time periods (e.g., slots) including sets of symbols having a full-duplex format. In this regard, the UE115-amay identify one or more slots having a full-duplex format. In some aspects, the UE115-amay identify the one or more time periods including sets of symbols having a full-duplex format based on the RRC message210, the configuration for interpreting RFIs, the control message215including the RFI, or any combination thereof.

In some aspects, the UE115-amay monitor the control message215for portions of the control message215associated with frequency resource allocations of the one or more slots including symbols having a full-duplex format. In this regard, the UE115-amay monitor one or more portions of the control message215based on identifying the one or more slots including symbols having a full-duplex format. For example, in cases where the UE115-aidentifies one or more slots including symbols having a full-duplex format, the UE115-amay monitor portions of the RFI and/or portions of the control message215reserved for indications of frequency resource allocations. By way of another example, in cases where the UE115-adoes not identify any slots including symbols having a full-duplex format, the UE115-amay refrain from monitoring portions of the RFI and/or portions of the control message215reserved for indications of frequency resource allocations.

In some aspects, the UE115-amay determine a frequency resource allocation for the one or more slots including symbols having a full-duplex format. Moreover, the UE115-amay determine a frequency resource allocation for slots including symbols having a full-duplex format on each component carrier associated with the UE115-a. In some aspects, the UE115-amay determine the frequency resource allocation for the slots including symbols with a full-duplex format based on the RRC message210, the configuration for interpreting RFIs, the control message215including the RFI, or any combination thereof. For example, in cases where the UE115-adetermines a resource format for each slot based on a first portion (e.g., first bit) of the RFI, the UE115-amay determine the frequency resource allocation based on a second portion (e.g., second bit) of the RFI. By way of another example, the UE115-amay determine the frequency resource allocation based on a portion of the control message215reserved for indications of frequency resource allocations for the RFIs of the control message215.

In cases where the UE115-aidentifies two or more slots including sets of symbols with a full-duplex format, the UE115-amay determine multiple frequency resource allocations. For example, the UE115-amay identify a first slot including a first set of symbols having a full-duplex format, and a second slot including a second set of symbols having a full-duplex format. In this example, the UE115-amay determine the resource format for each slot based on a first portion (e.g., first bit) of the RFI, determine a first frequency resource allocation for the first set of symbols having the full-duplex format based on a second portion (e.g., second bit) of the RFI, and determine a second frequency resource allocation for the second set of symbols having the full-duplex format based on a third portion (e.g., third bit) of the RFI. By way of another example, the UE115-amay determine frequency resource allocations for both the first and second sets of symbols having the full-duplex format based on a portion of the control message215reserved for indications of frequency resource allocations.

Moreover, as noted previously herein, the UE115-amay be configured with multiple configurations for interpreting RFIs based on a quantity of slots including symbols having a full-duplex format. In this regard, the UE115-amay utilize a first configuration to interpret the control message215and/or RFI in cases where the UE115-aidentifies a single full-duplex slot, and may utilize a second configuration to interpret the control message215and/or RFI in cases where the UE115-aidentifies two or more full-duplex slots.

In some aspects, the UE115-amay communicate with the base station105-abased on determining the resource format for each slot and determining the frequency resource allocation for full-duplex slots. For example, the UE115-amay transmit uplink transmissions220to the base station105-abased on the determined resource formats and frequency resource allocations, and may receive downlink transmissions225from the base station105-abased on the determined resource formats and frequency resource allocations.

The techniques described herein may provide for more flexible resource allocations. In particular, techniques described herein may support signaling for full-duplex formats, as well as signaling for frequency resource allocations associated with time periods including symbols having a full-duplex format. Moreover, by sending a single GC-DCI transmission to a group of UEs115which indicates RFIs (e.g., SFIs), the base station105-amay decrease the control signaling used to communicate RFIs, thereby reducing resource and messaging overhead within the wireless communications system200.

FIG.3illustrates an example of a resource allocation scheme300that supports RFIs in BWP management for full-duplex resource allocation in accordance with aspects of the present disclosure. In some examples, resource allocation scheme300may implement aspects of wireless communications system100or200.

In some aspects, the resource allocation scheme300may illustrate an example DCI305(e.g., enhanced DCI 2_0, DCI 2_x), and may illustrate how a UE115-aconfigured for full-duplex communications may receive and interpret enhanced DCI. In some aspects, a DCI305illustrated in the resource allocation scheme300may illustrate an example of the control message215illustrated inFIG.2.

In some aspects, a UE115may identify a configuration for interpreting RFIs310. Additionally, the UE115may receive a control message including one or more RFIs310. For example, as shown inFIG.3, the UE115may receive a DCI305, where the DCI305includes a set of RFIs310. The set of RFIs310may include a first RFI310-a, a second RFI310-b, a third RFI310-c, a fourth RFI310-d, a fifth RFI310-e, a sixth RFI310-f, and a seventh RFI310-g. In some aspects, the UE115may identify one or more indexes associated with the UE115, where the one or more indexes indicate a position of an RFI associated with the UE115. In some cases, the one or more indexes may be indicated via an RRC message, within a bit field the DCI305, or any combination thereof. For example, in some cases, the UE115may identify an index in a bit field of the DCI305, where the index indicates a position of the fifth RFI310-eassociated with the UE115. In some aspects, the one or more indexes may indicate one or more RFIs310within the DCI405associated with one or more component carriers associated with the UE115. For example, the UE115may identify a first index indicating a first RFI associated with a first component carrier of the UE115, and may identify a second index indicating a second RFI associated with a second component carrier of the UE115.

The fifth RFI310-emay be associated with one or more time periods (e.g., slots325) of communication resources allocated to the UE115. For example, as shown inFIG.3, the fifth RFI310-emay be associated with a first slot325-a, a second slot325-b, and a third slot325-c. In some aspects, the UE115may monitor the fifth RFI310-ebased on identifying the one or more indicators. The fifth RFI310-emay include a first portion315(e.g., “N bit”) and a second portion320-a(e.g., “M bit”). In some aspects, UE115may monitor the first portion315of the fifth RFI310-ebased on identifying the one or more indexes.

In some aspects, the first portion315of the fifth RFI310-emay indicate a resource format for each slot325associated with the fifth RFI310-e. For example, as shown inFIG.3, the first portion315of the fifth RFI310-emay indicate a full-duplex format associated with the first slot325-a, a downlink format associated with the second slot325-b, and an uplink format associated with the third slot325-c. In this regard, the UE115may determine a resource format for each time period (e.g., each slot325) based on the first portion315of the fifth RFI310-e.

In some aspects, the UE115may identify one or more time periods (e.g., one or more slots325) including symbols having a full-duplex format based on the first portion315of the fifth RFI310-e. In cases where the UE115identifies one or more slots325including symbols having a full-duplex format, the UE115may monitor subsequent portions of the fifth RFI310-ein order to identify frequency resource allocations330for the respective slots325including symbols having a full-duplex format. In some aspects, the UE115may identify indications of frequency resource allocations330associated with full-duplex formats based on subsequent portions of the fifth RFI310-e(e.g., second portion320-a, third portion320-b).

For example, as shown inFIG.3, the UE115may identify that the first slot325-aincludes symbols having a full-duplex format, and may thereby monitor the second portion320-aof the fifth RFI310-eto determine a frequency resource allocation330-afor the first slot325-a. In this example, the second portion320-amay indicate a frequency resource allocation330-aassociated with the first slot325-a. The frequency resource allocation330-amay include one or more frequency formats335. For example, the frequency resource allocation330-amay include a first frequency format335-a, a second frequency format335-b, a third frequency format335-c, and a fourth frequency format335-d. In some aspects, the frequency resource allocation330-amay be associated with each symbol of the first slot325-awhich has a full-duplex format.

In cases where the UE115identifies multiple slots325including symbols having a full-duplex format, the UE115may monitor multiple subsequent portions320of the fifth RFI310-eto identify frequency resource allocations330for the respective slots325including symbols having a full-duplex format. For example, in some cases, the UE115may identify that the first slot325-aand an additional slot325(e.g., second slot325-b, third slot325-c, fourth slot (not shown)) include symbols having a full-duplex format. In this example, the UE115may monitor the second portion320-aof the fifth RFI310-eto determine a first frequency resource allocation330-afor the first slot325-a, and may monitor the third portion320-bof the fifth RFI310-eto determine a second frequency resource allocation330-bfor the additional slot (not shown). In this example, the third portion320-bof the fifth RFI310-emay indicate the second frequency resource allocation330-bfor the additional slot. The second frequency resource allocation330-bmay include a first frequency format335-e, a second frequency format335-f, a third frequency format335-g, and a fourth frequency format335-h. In some aspects, the second frequency resource allocation330-bmay be associated with each symbol of the fourth slot which has a full-duplex format.

It is noted herein that the UE115may refrain from monitoring subsequent portions320of the fifth RFI310-edepending on a quantity of slots325having a full-duplex format that are identified. For example, in cases where the UE115identifies only a single slot325(e.g., first slot325-a) having a full-duplex format, the UE115may refrain from monitoring the third portion320-bof the fifth RFI310-e. Similarly, in cases where the UE115does not identify any slots325including symbols having a full-duplex format, the UE115may refrain from monitoring subsequent portions (e.g., second portion320-a, third portion320-b) of the fifth RFI310-e.

In some aspects, the frequency resource allocations330-aand330-bmay include frequency resources for uplink communications and downlink communications. In some cases, the frequency resource allocations330-aand330-bmay include a guard band between frequency resources for uplink communications and frequency resources for downlink communications. Additionally or alternatively, the frequency resource allocations330-aand330-bmay include an overlap between frequency resources for uplink communications and frequency resources for downlink communications.

FIG.4illustrates an example of a resource allocation scheme400that supports RFIs in BWP management for full-duplex resource allocation in accordance with aspects of the present disclosure. In some examples, resource allocation scheme400may implement aspects of wireless communications system100or200.

As compared to the resource allocation scheme300in which both resource formats and frequency resource allocations are indicated via portions of the fifth RFI310-e, the resource allocation scheme400may indicate frequency resource allocations via a reserved portion415of the control message (e.g., DCI405) which is reserved for indications of frequency resource allocations for the set of RFIs410indicated in the control message (e.g., DCI405). In this regard, the resource allocation scheme400may indicate resource formats via RFIs410, and may indicate frequency resource allocations for full-duplex slots425via the reserved portion415.

For example, as noted previously herein, a UE115may identify a configuration for interpreting RFIs410, and may receive a control message (e.g., DCI405) including one or more RFIs410. For instance, as shown inFIG.4, the UE115may receive a DCI405, where the DCI405includes a set of RFIs410. The set of RFIs410may include a first RFI410-a, a second RFI410-b, a third RFI410-c, a fourth RFI410-d, a fifth RFI410-e, a sixth RFI410-f, and a seventh RFI410-g. In some aspects, the UE115may identify one or more indexes associated with the UE115, where the one or more indexes indicate one or more portions of the DCI405which the UE115is to monitor. The one or more indexes may indicate one or more RFIs within the DCI505associated with one or more component carriers associated with the UE115.

For example, the UE115may identify (via an RRC message, the DCI405, or both) a first index indicating for the UE115to monitor a first portion of the DCI405, and a second index indicating for the UE115to monitor a second portion of the DCI405different from the first portion. In this example, the first portion of the DCI405may include the fifth RFI410-e, and the second portion of the DCI405may include a reserved portion415of the DCI405which is reserved for indications of frequency resource allocations for the set of RFIs410of the DCI405.

Continuing with the same example, the UE115may monitor the first portion (e.g., the fifth RFI410-e) of the DCI405based on identifying the first index. In some aspects, the fifth RFI410-emay indicate a resource format for each time period associated with the fifth RFI410-e. For example, as shown inFIG.4, the fifth RFI410-emay be associated with three slots425(e.g., a first slot425-a, a second slot425-b, and a third slot425-c). In this example, the fifth RFI410-emay indicate a full-duplex format associated with the first slot425-a, a downlink format associated with the second slot425-b, and an uplink format associated with the third slot425-c. In this regard, the UE115may determine a resource format for each time period (e.g., each slot425) based on the fifth RFI410-e.

Similarly, the UE115may monitor the second portion (e.g., reserved portion415) of the DCI405based on identifying the second index. In some aspects, the reserved portion415may include the last bit of the DCI405. The reserved portion415may include multiple portions which indicate frequency resource allocations430for slots425including symbols having full-duplex format. In this regard, the UE115may monitor none, all, or a subset of the reserved portion415dependent upon a quantity of slots425which are identified as including symbols having a full-duplex format. For example, in cases where the UE115does not identify any full-duplex slots435, the UE115may refrain from monitoring the reserved portion415. By way of another example, in cases where the UE115identifies a single slot425(e.g., first slot425-a) including symbols having a full-duplex format, the UE115may monitor a first portion420-aof the reserved portion415. In this example, the first portion420-aof the reserved portion415may indicate a first frequency resource allocation430-afor the first slot435-a. By way of another example, in cases where the UE115identifies that the first slot425-aand an additional slot (e.g., a second slot425-b, a third slot425-c, an additional slot (not shown)) each include symbols having a full-duplex format, the UE115may monitor a first portion420-aand a second portion420-bof the reserved portion415.

In this example, the first portion420-aof the reserved portion415may indicate a first frequency resource allocation430-afor the first slot435-a, and the second portion420-bmay indicate a second frequency resource allocation430-bfor the fourth slot. The first frequency resource allocation430-amay include a frequency format435-a, a frequency format435-b, a frequency format435-c, and a frequency format435-d. Likewise, the second frequency resource allocation430-bmay include a frequency format435-e, a frequency format435-f, a frequency format435-g, and a frequency format435-h.

In some aspects, the frequency resource allocations430-aand430-bmay include frequency resources for uplink communications and downlink communications. In some cases, the frequency resource allocations430-aand430-bmay include a guard band between frequency resources for uplink communications and frequency resources for downlink communications. Additionally or alternatively, the frequency resource allocations430-aand430-bmay include an overlap between frequency resources for uplink communications and frequency resources for downlink communications.

FIG.5illustrates an example of a resource allocation scheme500that supports RFIs in BWP management for full-duplex resource allocation in accordance with aspects of the present disclosure. In some examples, resource allocation scheme500may implement aspects of wireless communications system100or200.

In additional or alternative aspects, a configuration for interpreting RFIs may include a combined configuration including a time resource allocation scheme and a frequency resource allocation scheme. In such cases, a UE115may use the combined configuration to interpret both resource formats and frequency resource allocations based on an RFI510.

For example, a UE115may identify a configuration for interpreting RFIs510, where the configuration includes a combined configuration including a time resource allocation scheme and a frequency resource allocation scheme. Additionally, the UE115may receive a control message including one or more RFIs510. For example, as shown inFIG.5, the UE115may receive a DCI505, where the DCI505includes a set of RFIs510. The set of RFIs510may include a first RFI510-a, a second RFI510-b, a third RFI510-c, a fourth RFI510-d, a fifth RFI510-e, a sixth RFI510-f, and a seventh RFI510-g. In some aspects, the UE115may identify one or more indexes associated with the UE115, where the one or more indexes indicate a position of an RFI associated with the UE115. In some cases, the one or more indexes may be indicated via an RRC message, within a bit field the DCI505, or any combination thereof. For example, in some cases, the UE115may identify an index in a bit field of the DCI505, where the index indicates a position of the fifth RFI510-eassociated with the UE115. In some aspects, the one or more indexes may indicate one or more RFIs510within the DCI405associated with one or more component carriers associated with the UE115.

In some aspects, the fifth RFI510-emay be associated with one or more time periods of communication resources allocated to the UE115. For example, as shown inFIG.5, the fifth RFI510-emay be associated with a first slot525-a, a second slot525-b, a third slot525-c, and a fourth slot525-d. Additionally, the fifth RFI510-emay include a storage object515(e.g., table, index) including one or more joint time-frequency formats520. For example, the storage object515may include first joint time-frequency format520-a, a second joint time-frequency format520-b, and a third joint time-frequency format520-c. The joint time-frequency formats520may indicate both a resource format (e.g., uplink format, downlink format, full-duplex format) associated with each slot525, as well as a frequency resource allocation for each slot525including a full-duplex format.

Accordingly, in some aspects, the UE115may determine a resource format for each slot525based on the fifth RFI510-eand the time resource allocation scheme of the configuration for interpreting RFIs510. Additionally, the UE115may determine a frequency resource allocation for each full-duplex slot525based on the fifth RFI510-eand the frequency resource allocation scheme of the configuration for interpreting RFIs510.

In some aspects, the frequency resource allocations indicated in the joint time-frequency formats520may include frequency resources for uplink communications and downlink communications. In some cases, the frequency resource allocations indicated in the joint time-frequency formats520may include a guard band between frequency resources for uplink communications and frequency resources for downlink communications. Additionally or alternatively, the frequency resource allocations indicated in the joint time-frequency formats520may include an overlap between frequency resources for uplink communications and frequency resources for downlink communications.

FIG.6illustrates an example of a process flow600that supports RFIs in BWP management for full-duplex resource allocation in accordance with aspects of the present disclosure. In some examples, process flow600may implement, or be implemented by, aspects of wireless communications systems100or200or resource allocation schemes300,400, or500. For example, the process flow600may illustrate identifying a configuration for interpreting RFIs, determining a resource format for one or more slots, determining a frequency resource allocation for full-duplex slots, and communicating based on the determined resource formats and/or determined frequency resource allocations, as described with reference toFIGS.1through5, among other aspects. The process flow600may include a UE115-band a base station105-b, which may be examples of UEs115and base stations105, as described with reference toFIGS.1and2.

At605, the base station105may transmit an RRC message including an indication of a configuration for interpreting RFIs (e.g., SFIs) associated with the UE115-b. The RFIs may indicate one or more resource formats associated with one or more time periods of communication resources allocated to the UE115-b. For example, the one or more resource formats indicated by the RFIs may include a downlink format, an uplink format, or a full-duplex format. In this regard, the indication of the configuration for interpreting RFIs may include a configuration for how the UE115-bis to interpret index values of an RFI, and determine resource formats based on the index value.

In additional or alternative aspects, the configuration for interpreting RFIs indicated in the RRC message may include a time resource allocation scheme and a frequency resource allocation scheme. In this regard, the configuration indicated to the UE115-bmay include a configuration for interpreting both resource formats and frequency resource allocations based on RFIs. In this regard, the configuration for interpreting RFIs may include a joint-configuration which is used to determine both time and frequency resources.

At610, the UE115-bmay identify the configuration for interpreting RFIs. In some aspects, the UE115-emay identify the configuration for interpreting RFIs based on receiving the RRC message from the base station at605. Additionally or alternatively, the UE115-bmay be preconfigured with the configuration for interpreting RFIs, and may thereby identify the configuration at610without receiving the RRC message at605. In some aspects, the UE115-bmay identify the configuration for interpreting RFIs based on a capability of the UE115-bto recognize full-duplex formats.

In some aspects, the UE115-bmay identify one or more configurations for interpreting RFIs. For example, in some cases, the UE115-bmay identify a first configuration associated with RFIs indicating a single time period (e.g., single slot) including a set of symbols having a full-duplex format, and may identify a second configuration associated with RFIs indicating a two or more time periods (e.g., single slot) including a set of symbols having a full-duplex format.

At615, the UE115-bmay receive a control message from the base station105-b. The control message may include an RFI (e.g., SFI) for one or more time periods (e.g., slots) of communication resources allocated to the UE115-b. The control message may include DCI, GC-DCI, or the like. For example, the control message may include an enhanced DCI (e.g., DCI 2_0, DCI 2_x) which is used to indicate both resource formats (e.g., uplink format, downlink format, full-duplex format) as well as frequency resource allocations for slots having a full-duplex format. In some aspects, at least one time period (e.g., at least one slot) of the one or more time periods allocated to the UE115-band associated with the control message may include a time period (e.g., slot) including a set of symbols having a full-duplex format (e.g., full-duplex slot). In some aspects, the UE115-bmay receive the control message at615based on a capability of the UE115-bto recognize full-duplex formats.

At620, the UE115-bmay identify one or more indexes associated with the UE115-b. The one or more indexes may include indications for the UE115-bto monitor certain portions of the control message which are pertinent to the UE115-b. In some aspects, the UE115-bmay identify the one or more indexes based on the RRC message received at605, the control message received at615, other signaling from the base station105-b, or any combination thereof. Moreover, the UE115-bmay identify the one or more indexes based on a capability of the UE115-bto recognize full-duplex formats. For example, the first few slots of the control message received at615may include one or more indexes indicating portions of the control message that the UE115-bis to monitor to determine resource allocations. For instance, the UE115-bmay identify, within the control message, an index associated with the UE115-b, where the index indicates a position of an RFI associated with the UE115-bwithin the control message.

In some aspects, the UE115-bmay identify a single index which indicates for the UE115-bto monitor one or more portions of the control message. Additionally or alternatively, the UE115-bmay identify multiple indexes which indicate for the UE115-bto monitor multiple portions of the control message. For example, in some cases, the UE115-bmay identify a first index within the control message, where the first index indicates for the UE115-bto monitor a first portion of the control message. Continuing with the same example, the UE115-bmay identify a second index within the control message, where the second index indicates for the UE115-bto monitor a second portion of the control message which is different from the first portion. For instance, the first portion of the control message indicated by the first index may include an RFI, and the second portion of the control message indicated by the second index may include a portion of the control message which is reserved for indications of frequency resource allocations for the RFIs included within the control message.

At635, the UE115-bmay monitor the control message, or portions of the control message. In some aspects, the UE115-bmay monitor the control message, or portions of the control message, based on identifying the one or more indexes at620. For example, in cases where the UE115-bidentifies a single index indicating a position of an RFI within the control message, the UE115-bmay monitor the portion of the control message including the RFI based on identifying the indication. By way of another example, in cases where the UE115-bidentifies a first index indicating a position of an RFI within the control message, and a second index indication a position of the control message reserved for indications of frequency resource allocations, the UE115-bmay monitor portions of the control message including the RFI and the portion of the control message reserved for indications of frequency resource allocations.

At630, the UE115-bmay determine a resource format (e.g., uplink format, downlink format, full-duplex format) for each time period (e.g., each slot) allocated to the UE115-b. In some aspects, the UE115-bmay determine the resource formats at630based on the RRC message at605, identifying the configuration for interpreting RFIs at610, receiving the control message and RFI at615, identifying the one or more indexes at620, monitoring the control message at625, or any combination thereof. For example, the UE115-bmay determine a resource format for each time period based on at least a portion of the RFI.

At635, the UE115-bmay identify one or more time periods (e.g., slots) including a set of symbols having a full-duplex format. In this regard, the UE115-bmay identify one or more slots having a full-duplex format. In some aspects, the UE115-bmay identify the one or more time periods including sets of symbols having a full-duplex format based on receiving the RRC message including the configuration at605, identifying the configuration at610, receiving the control message and RFI at615, identifying the one or more indexes at620, monitoring the control message at625, determining the resource format for each slot at635, or any combination thereof.

At640, the UE115-bmay monitor the control message. In some aspects, the UE115-bmay monitor the control message for portions of the control message associated with frequency resource allocations of the one or more full-duplex slots identified at635. In this regard, the UE115-bmay monitor one or more portions of the control message based on identifying the one or more full-duplex slots at635. For example, in cases where the UE115-bidentifies one or more slots including a set of full-duplex symbols at635, the UE115-bmay monitor portions of the RFI and/or portions of the control message reserved for indications of frequency resource allocations. By way of another example, in cases where the UE115-bdoes not identify any full-duplex symbols at635, the UE115-bmay refrain from monitoring portions of the RFI and/or portions of the control message reserved for indications of frequency resource allocations.

At645, the UE115-bmay determine a frequency resource allocation for the one or more slots including sets of symbols having a full-duplex format. In some aspects, the UE115-bmay determine the frequency resource allocation for the slots including sets of symbols with a full-duplex format based on receiving the RRC message including the configuration at605, identifying the configuration at610, receiving the control message and RFI at615, identifying the one or more indexes at620, monitoring the control message at625, determining the resource format for each slot at635, monitoring the control message at645, or any combination thereof.

For example, in cases where the UE115-bdetermines a resource format for each slot based on a first portion (e.g., first bit) of the RFI at630, the UE115-bmay determine the frequency resource allocation at645based on a second portion (e.g., second bit) of the RFI. By way of another example, the UE115-bmay determine the frequency resource allocation at645based on a portion of the control message reserved for indications of frequency resource allocations for the RFIs of the control message.

In cases where the UE115-bidentifies two or more slots including sets of symbols with a full-duplex format, the UE115-bmay determine multiple frequency resource allocations at645. For example, at635, the UE115-bmay identify a first slot including a first set of symbols having a full-duplex format, and a second slot including a second set of symbols having a full-duplex format. In this example, the UE115-bmay determine the resource format for each slot based on a first portion (e.g., first bit) of the RFI, determine a first frequency resource allocation for the first set of symbols having the full-duplex format based on a second portion (e.g., second bit) of the RFI, and determine a second frequency resource allocation for the second set of symbols having the full-duplex format based on a third portion (e.g., third bit) of the RFI. By way of another example, the UE115-bmay determine frequency resource allocations for both the first and second sets of symbols having the full-duplex format based on a portion of the control message reserved for indications of frequency resource allocations.

At650, the UE115-bmay communicate with the base station105-b. In some aspects, the UE115-bmay communicate with the base station105-bbased on determining the resource format for each slot at630and determining the frequency resource allocation at645. For example, the UE115-bmay transmit uplink transmissions to the base station105-bbased on the determined resource formats and frequency resource allocations, and may receive downlink transmissions from the base station105-bbased on the determined resource formats and frequency resource allocations.

The techniques described herein may provide for more flexible resource allocations. In particular, techniques described herein may support signaling for full-duplex formats, as well as signaling for frequency resource allocations associated with time periods including symbols having a full-duplex format. Moreover, by sending a single GC-DCI transmission to a group of UEs115which indicates RFIs (e.g., SFIs), the base station105-bmay decrease the control signaling used to communicate RFIs, thereby reducing resource and messaging overhead within wireless communications systems.

FIG.7illustrates an example of a wireless communications system700that supports RFIs in BWP management for full-duplex resource allocation in accordance with aspects of the present disclosure. In some examples, the wireless communications system700may implement aspects of wireless communications systems100or200. Wireless communications system700may include base station105-c, UE115-c, and UE115-d, which may correspond to a base station105and UEs115as described with reference toFIGS.1and2. Base station105-cmay be associated with coverage area110-a, and UE115-cand UE115-dmay communicate with base station105-c. UE115-cmay perform a BWP updating procedure710based on receiving a control message705(e.g., a GC-DCI message) from base station105-cto dynamically update an active BWP for communication.

UE115-cand UE115-dmay be associated with base station105-c. In some cases, UE115-cmay be pre-configured with a frequency resource table, while in some additional or alternative cases, UE115-cmay generate a frequency resource table as part of an RRC procedure. For example, base station105-cmay transmit an RRC configuration message indicating configurations for the frequency resource table to UE115-c. The frequency resource table may include a number of frequency resource configurations for a component carrier. For example, the frequency resource table may include a number of configurations that allocate uplink and downlink frequency resources within a component carrier.

UE115-cmay communicate with base station105-cin accordance with an operating BWP. For example, UE115-cmay be configured with the operating BWP as part of an RRC procedure or based on other UE-specific signaling. The operating BWP may include an active uplink BWP, an active downlink BWP, or both for a component carrier in which UE115-cmay communicate. UE115-cmay receive a control message705(e.g., a GC-DCI message) in accordance with the operating BWP. The control message705may include a resource format indication, such as an SFI, for UE115-c. An SFI may indicate one or more slot formats (e.g., an uplink format, a downlink format, a flexible format, a full-duplex format, or any other format including combinations of these formats) and a set of frequency resources (e.g., a slot frequency format, a BWP pair, or a BWP and an RBW). In some cases, the control message705may include the set of frequency resources based on the SFI indicating a full-duplex format (e.g., a format including one or more symbols allocated for uplink and downlink communications) for one or more slots. In some cases, the base station105-cmay transmit a GC-DCI to UE115-cand UE115-d. UE115-cmay identify a relevant SFI based on an SFI position or index associated with UE115-c, while UE115-dmay identify a relevant SFI (e.g., a different SFI or the same SFI) based on an SFI position or index associated with UE115-d.

UE115-cmay perform a BWP updating procedure710based on receiving the control message705. For example, UE115-cmay perform the BWP updating procedure710based on receiving a GC-DCI message that indicates a set of frequency resources for UE115-c, indicates a slot corresponding to a full-duplex format for UE115-c, or both. As part of the BWP updating procedure710, UE115-cmay modify the operating BWP based on the set of frequency resources indicated in the control message705. In some cases, the set of frequency resources may correspond to a slot frequency format, and UE115-cmay modify the operating BWP by reducing the operating BWP to frequency resources of the operating BWP that overlap with the frequency resources of the slot frequency format. Reducing an operating BWP to frequency resources that overlap with a slot frequency format may reduce system latency (e.g., as compared to performing a BWP switching procedure, which may involve channel estimation procedures or other calibration processes to determine parameters for communicating in the switched BWP).

In some other examples, as part of the BWP updating procedure710, UE115-cmay modify the operating BWP by switching the operating BWP to the set frequency resources indicated in the control message705(e.g., a different operating BWP). The set of frequency resources may correspond to a slot frequency format, and UE115-cmay modify the operating BWP by switching the operating BWP to the slot frequency format indicated in the control message705. For example, a full-duplex UE may update the operating BWP to an uplink band and a downlink band indicated by the slot frequency format information and operate in a full-duplex mode. In some additional or alternative examples, a full-duplex aware UE (e.g., a UE that may identify full-duplex resources but may operate in a half-duplex mode) may switch the operating BWP to a new BWP indicated by the slot frequency format information and operate in a half-duplex mode.

In some cases, the set of frequency resources indicated in the control message705may correspond to a BWP identifier (ID), and UE115-cmay modify the operating BWP based on the BWP ID. For example, UE115-cmay be configured with a number of BWP IDs (e.g., for a component carrier, based on an RRC procedure). The control message705may indicate a BWP ID, and UE115-cmay modify the operating BWP based on the indicated BWP ID (e.g., by switching to an uplink and downlink BWP pair corresponding to the BWP ID). In some additional or alternative examples, the set of frequency resources indicated in the control message705may correspond to a BWP and an RBW (e.g., a usable portion of the bandwidth for UE115-c) for the BWP.

UE115-cmay transmit an uplink message715to base station105-cbased on the BWP updating procedure710. For example, UE115-cmay transmit the uplink message715to base station105-caccording to the resources indicated in the control message705. In some cases, UE115-cand base station105-cmay communicate according to a full-duplex mode of operation, in which UE115-cmay receive a downlink message concurrent to transmitting the uplink message715. The downlink transmissions and uplink transmission may occur in the modified operating BWP for UE115-c. In some examples, base station105-cmay perform a similar BWP updating procedure710to UE115-dto track the active BWPs for communications with UE115-d.

FIG.8illustrates an example of a resource allocation scheme800that supports RFIs in BWP management for full-duplex resource allocation in accordance with aspects of the present disclosure. In some example, the resource allocation scheme800may implement aspects of wireless communications systems100,200, or700. Aspects of the resource allocation scheme800may be implemented by a UE115, the components of a UE115, a base station105, or the components of a base station105as described herein.

The resource allocation scheme800may be based on a DCI805(e.g., a DCI message of DCI format 2_0, enhanced DCI format 2_0, or any other DCI format supporting information for a group of UEs115, DCI 2_X). The resource allocation scheme800may illustrate how a full-duplex or full-duplex aware UE115may be configured for communications with a base station105. The DCI805may be an example of the control message705described with reference toFIG.7. In some cases, the DCI805may include a DCI payload including RFI810-a, RFI810-b, RFI810-c, RFI810-d, RFI810-e, RFI810-f, and RFI810-g. In some cases, the DCI payload may include additional or alternative information for a group of UEs115.

A UE115may identify a configuration for interpreting RFIs810. The UE115may receive a control message including one or more RFIs810and may determine slot information based on the configuration. For example, as shown inFIG.8, the UE115may receive a DCI805, where the DCI805includes a set of RFIs810. The UE115may identify one or more indexes associated with the UE115, where the one or more indexes indicate a position of an RFI810associated with the UE115. For example, as described with reference toFIG.7, UE115-cmay identify an RFI at a first index (e.g., RFI810-e) and UE115-dmay identify an RFI at a second index (e.g., RFI810-a). In this way, the DCI805may be a GC-DCI; a group of UEs115may receive the DCI805and determine different, UE-specific information from the DCI805. In some cases, the one or more indexes may be indicated via an RRC message, within a bit field of a DCI message, or any combination thereof. For example, the UE115may identify an index in an RRC configuration message (e.g., a positionInDCI value), where the index indicates a position of an RFI810associated with the UE115. The index may indicate one or more RFIs810within the DCI805associated with one or more component carriers of the UE115. In some cases, the UE115may identify a first index indicating a first RFI810associated with a first component carrier of the UE115and a second index indicating a second RFI810associated with a second component carrier of the UE115.

RFI810-emay be associated with one or more time periods (e.g., slots825) of communication resources allocated for the UE115. For example, as shown inFIG.8, RFI810-emay be associated with a first slot825-a, a second slot825-b, and a third slot825-c. The UE115may decode the RFI810-ebased on identifying the one or more indexes. The RFI810-emay include a first portion815(e.g., including N bits) and a second portion820(e.g., including M bits). In some cases, the UE115may decode the first portion815of the RFI810-ebased on identifying the one or more indexes and may decode the second portion820based on information included in the first portion815.

The first portion815of the RFI810-emay configure time resource information for one or more UEs115. In some cases, the first portion815of the RFI810-emay indicate a resource format for each slot825associated with the RFI810-e. For example, as shown inFIG.8, the first portion815of the RFI810-emay indicate a full-duplex format associated with the first slot825-a, a downlink format associated with the second slot825-b, and an uplink format associated with the third slot825-c. A slot825may contain any combination of full-duplex format symbols, downlink format symbols, uplink format symbols, or flexible format symbols. The UE115may determine a resource format for each time period (e.g., each slot825, each symbol of each slot825, etc.) associated with RFI810-ebased on the first portion815of the RFI810-e.

In some cases, the UE115may identify one or more time periods (e.g., one or more slots825) that include symbols corresponding to a full-duplex format based on the first portion815of the RFI810-e. If the UE115identifies one or more slots825that include symbols corresponding to a full-duplex format, the UE115may decode a subsequent portion of the RFI810-eto identify a set of frequency resources835of the frequency resource allocation. The UE115may store a frequency resource table830associated with a component carrier840in memory. This frequency resource table830may be pre-configured at the UE115or configured by a base station105(e.g., using RRC signaling). In some cases, the UE115may identify an indication of a set of frequency resources835based on a slot825including one or more symbols associated with a full-duplex format or the second portion820of the RFI810-eincluding the indication of the set of frequency resources835.

For example, as shown inFIG.8, the UE115may identify that the first slot825-aincludes symbols having a full-duplex format and may decode the second portion820of the RFI810-eto determine a set of frequency resources835from the frequency resource table830. For example, the frequency resource table830(e.g., a lookup table in memory or some other format for storing multiple sets of frequency resource allocations) may include a first set of frequency resources835-a, a second set of frequency resources835-b, a third set of frequency resources835-c, and a fourth set of frequency resources835-d. In some cases, the frequency resource table830may be associated with a component carrier, and the UE115may be associated with multiple components carriers. The second portion820of the RFI810-emay indicate a set of frequency resources835of the frequency resource table830, a specific component carrier840, or a combination thereof.

In some examples, the number of bits, M, included in the second portion820of the RFI810-emay be based on the number of configured sets of frequency resources835at the UE115. For example, to support a selection between four sets of frequency resources835, the second portion820may include 2 bits, with a bit value {00} indicating the first set of frequency resources835-a, a bit value {01} indicating the second set of frequency resources835-b, a bit value {10} indicating the third set of frequency resources835-c, and a bit value {11} indicating the fourth set of frequency resources835-d. As such, the size of the second portion820of the RFI810-emay be dynamic (e.g., based on the indication options for the UE115). Similarly, the number of bits, N, for the first portion815of the RFI810-emay be dynamic based on the indication options for slot format combinations. For example, the UE115may store a number of slot format combination IDs corresponding to combinations of slot formats, and the base station105may indicate a slot format combination (e.g., the combination of slot825-a, slot825-b, and slot825-c) using a bit value in the first portion815to indicate a slot format combination ID.

A set of frequency resources835of the frequency resource table830may correspond to a slot frequency format, a BWP pair, a BWP and an RBW, or some combination of these or other frequency allocations. The UE115may modify an operating BWP (e.g., an active uplink BWP and an active downlink BWP) based on the indicated set of frequency resources835. In some examples, the UE115may modify the operating BWP upon determining the indicated set of frequency resources835. In some other examples, the UE115may modify the operating BWP prior to the slot825including one or more full-duplex format symbols (e.g., slot825-a). The UE115may continue to communicate according to the modified operating BWP in subsequent slots825(e.g., even in slots825not including full-duplex format symbols). In some cases, a set of frequency resources835may include a guard band between frequency resources for uplink communications and frequency resources for downlink communications. Additionally or alternatively, a set of frequency resources835may include an overlap between frequency resources for uplink communications and frequency resources for downlink communications.

FIG.9illustrates an example of resource allocation schemes901and902that support RFIs in BWP management for full-duplex resource allocation in accordance with aspects of the present disclosure. In some examples, the resource allocation schemes901and902may implement aspects of wireless communications systems100,200, or700. The techniques described in reference to resource allocation schemes901and902may be implemented by a UE115or its components as described herein. Additionally or alternatively, a base station105or its components may implement one or more of the techniques described herein to track operating (e.g., active) BWPs for one or more UEs115.

A UE115may be associated with an operating BWP905, receive a downlink message (e.g., a control message705as described with reference toFIG.7, a DCI805as described with reference toFIG.8), and modify the operating BWP905based on the received downlink message. In some cases, the UE115may be a full-duplex UE or a full-duplex aware UE, and the downlink message may indicate one or more resources corresponding to a full-duplex format. Modifying an operating BWP905based on receiving the downlink message may improve resource efficiency and reduce communication latency.

The UE115may be associated with an operating BWP905corresponding to component carrier920-a. In some cases, component carriers920-aand920-bmay correspond to the same component carrier of the UE115. In some cases, the operating BWP905may include an uplink BWP and a downlink BWP. The uplink BWP may include a set of frequency resources allocated for the UE115to transmit uplink messages and the downlink BWP may include a set of frequency resources allocated for the UE115to receive downlink messages. The UE115may receive a downlink message from the base station105that includes an SFI indicating a set of frequency resources915(e.g., frequency resources915-a), modify the operating BWP905based on the set of frequency resources915, and communicate with the base station using the modified BWP.

In some cases, the UE115may reduce the operating BWP905to a modified BWP910such that the frequency resources of the modified BWP910correspond to the overlapping frequency resources of the operating BWP905and the indicated set of frequency resources915-a. For example, the UE115may reduce the operating BWP905to modified BWP910, and the frequency resources of modified BWP910may correspond to the overlapping uplink frequency resources and the overlapping downlink frequency resources of the operating BWP905and the set of frequency resources915-a. In this way, the UE115may communicate using a functional BWP that may not correspond to a configured BWP for the UE115, but instead may correspond to a subset of frequency resources for a BWP configured for the UE115. Reducing an operating BWP905to frequency resources that overlap with the set of frequency resources915indicated in a downlink message may reduce system latency, as the UE115may refrain from performing a BWP switch (e.g., including channel estimation). That is, because the UE115has previously configured the operating BWP905, using a reduced BWP that includes resources already configured for the operating BWP905(and no resources not configured for the operating BWP905) may reduce the processing overhead associated with modifying the operating BWP.

In some cases, the UE115may switch the operating BWP905to a modified BWP such that the frequency resources of the modified BWP correspond to the set of frequency resources915-aindicated in the downlink message. For example, the UE115may switch the uplink and/or downlink resources of the operating BWP905to the uplink and/or downlink resources of the set of frequency resources915-a. As such, a base station105may trigger a BWP switch at the UE115using a GC-DCI message.

In some additional or alternative examples, the uplink resources of the set of frequency resources915may overlap with the downlink resources of the set of frequency resources915. As shown in the set of frequency resources915-b, a portion of the uplink resources may overlap with a portion of the downlink resources. As shown in the set of frequency resources915-c, all of the uplink resources may overlap with a portion of the downlink resources. In some cases, the UE115may activate and/or deactivate a number of antennas based on the received downlink message, the modified BWP, or both. Switching the frequency resources of an operating BWP905based on a set of frequency resources915indicated in a downlink message may improve data throughput.

In some cases, the set of frequency resources915may correspond to a slot frequency indication. The slot frequency indication may indicate or identify a frequency format for the UE115(e.g., a set of frequency resources835as described with reference toFIG.8). In some additional or alternative cases, the set of frequency resources915may correspond to a BWP indication. For example, a base station105may configure the UE115with a number of BWP frequency resource configurations to match the uplink and/or downlink frequency bands used in slots corresponding to a full-duplex format as part of an RRC procedure, and the slot frequency indication may include a BWP indication. The BWP indication may indicate or identify a pair of BWPs, including an uplink BWP and a downlink BWP for use in the slots corresponding to a full-duplex format (e.g., and, in some cases, subsequent slots after a BWP switch or reduction). For communicating with a base station105in slots corresponding to a full-duplex format, a full-duplex and/or a full-duplex aware UE may switch uplink and downlink resources to the uplink and downlink resources indicated by the BWP indication. A full-duplex aware UE may operate in a half-duplex mode during the slots that correspond to a full-duplex format. In some cases, the half-duplex pattern may be based on an RRC configuration or may be indicated in a DCI message. A full-duplex UE may operate in a full-duplex mode (e.g., concurrent uplink and downlink communication) during the slots that correspond to a full-duplex format. In some additional or alternative cases, the set of frequency resources915may include an indication of a BWP as well as an RBW for the BWP for the slots corresponding to a full-duplex format.

The SCS of uplink resources corresponding to the modified BWP may be the same or different from the SCS of downlink resources corresponding to the modified BWP. For example, the uplink SCS may be the same as the downlink SCS for a UE115operating according to a full-duplex mode (e.g., for full-duplex frequency-division duplexing (FDD) operation). In some cases, the uplink SCS may be the same as the downlink SCS because the uplink and downlink symbols corresponding to the full-duplex format may be shared within a slot (e.g., supporting concurrent downlink and uplink communications). In some additional or alternative examples, the uplink SCS may be different from the downlink SCS for a UE operating according to a half-duplex mode (e.g., for half-duplex time-division duplexing (TDD) operation by a full-duplex aware UE115). In some cases, a downlink message (e.g., an SFI in a DCI message, an RRC configuration message, etc.) may indicate one or more SCS configurations (e.g., SCS1, SCS2), and the UE115may determine the SCS for the uplink resources and the SCS for the downlink resources based on the indicated one or more SCS configurations.

A UE115may modify the operating BWP905based on the set of frequency resources915or an indication of the set of frequency resources915. The UE115may modify the operating BWP905based additionally or alternatively on a frequency resource table. The UE may generate or identify a number of frequency resource tables for one or more component carriers. In some cases, a frequency resource table may include one or more bit maps. For example, a bit map may indicate a communication direction (e.g., uplink or downlink) for a frequency range based on the value and index of each bit. The index of each bit may correspond to a frequency range within a component carrier, and the value of each bit may correspond to a communication direction. In some additional or alternative examples, a first bit map may be used to indicate frequency resources for a first communication direction (e.g., uplink), and a second bit map may be used to indicate frequency resources for a second communication direction. The index of each bit in the first and second bit maps may indicate a frequency resource (e.g., a resource element (RE), a resource block (RB), a resource block group (RBG), or some combination thereof) within a component carrier and the value of each bit may indicate a status (e.g., an active status, an inactive status, an available status, an unavailable status). Using an uplink bit map and a downlink bit map may improve resource flexibility. For example, the use of an uplink bit map as well as a downlink bit map may facilitate the use of guard bands between uplink and downlink resources and/or the use of overlapping uplink and downlink resources.

In some additional or alternative cases, the frequency resource table may include one or more resource indication values (RIVs) to represent a disjoint frequency allocation. An RIV may indicate both a frequency starting location (e.g., a RE, an RB, or an RBG starting location) and a number of frequency resources (e.g., a number of REs, RBs, RBGs, or a combination thereof). In some examples, the UE115may store one or more RIVs indicating uplink frequency resources and one or more RIVs indicating downlink frequency resources. In some cases, the frequency resource table may include a frequency resource starting location, a number of frequency resources, and one or more reserved resources. For example, for uplink resource allocation, the uplink frequency resources may span from the frequency resource starting location for the number of frequency resources, except for any reserved resources in the span (which may be reserved for downlink or no communications). The reserved resources may correspond to uplink resources, downlink resources, or a guard band. Including reserved resources in the frequency scheduling table may reduce system interference.

A half-duplex UE (e.g., a non-full-duplex UE, a non-full-duplex aware UE) may receive a set of frequency resources915and refrain from modifying an operating BWP905based on a mode of operation corresponding to the UE (e.g., a half-duplex mode). In some cases, a base station105may refrain from indicating frequency resources915to a non-full-duplex aware UE in a GC-DCI message. For example, an RFI transmitted in a GC-DCI message for one or more UEs that are not full-duplex aware may not include a second portion indicating frequency configuration information. A full-duplex UE may receive frequency information in a GC-DCI message and may consider the uplink and downlink bands of the indicated set of frequency resources915(or a portion that overlaps with the previous operating BWP905) as the new operating BWP905. A full-duplex aware UE may switch or reduce the uplink and downlink resources of the operating BWP905based on the indicated set of frequency resources915and operate in a half-duplex mode.

FIG.10illustrates an example of a resource allocation scheme1000that supports RFIs in BWP management for full-duplex resource allocation in accordance with aspects of the present disclosure. In some examples, the resource allocation scheme1000may implement aspects of the wireless communications systems100,200, or700. The resource allocation scheme1000may support one or more RBWs indicating the usable resources in a BWP for a UE115, as described with reference toFIGS.7through9.

The frequency resource allocations indicated in a joint time-frequency format1001may include frequency resources for uplink communications and downlink communications. The joint time-frequency format1001may be associated with one or more time periods of communication resources allocated to a UE. For example, as shown inFIG.10, the joint time-frequency format1001may be associated with a first slot1010-a, a second slot1010-b, a third slot1010-c, and a fourth slot1010-d.

In some cases, the frequency resource allocations indicated in the joint time-frequency format1001may include a guard band between frequency resources for uplink communications and frequency resources for downlink communications. For example, the usable bandwidth within a BWP may be reduced or compromised due to the uplink band (e.g., for physical uplink shared channel (PUSCH) transmission) and/or the guard band present in the second slot1010-band the third slot1010-c. The RBWs1015, as shown in1002, may mitigate the negative effects of uplink and downlink resources both being present within a BWP. In some cases, a UE may identify an RBW1015based on a DCI and communicate with a base station based on the identified RBW1015. For example, the UE may identify RBW1015-cbased on a frequency indication in a GC-DCI message and may transmit uplink data according to the uplink bandwidth indicated in RBW1015-cand receive downlink data according to the downlink bandwidth indicated in RBW1015-c. These bandwidths may be subsets of an active BWP1005for the UE, where the subsets support guard bands between uplink and downlink transmissions. The RBWs1015(e.g., RBW1015-a, RBW1015-b, RBW1015-c, and RBW1015-d) may be within the BWP of the UE, which may reduce or eliminate bandwidth switching delays associated with the UE. In some examples, a base station105may jointly indicate a BWP identifier (ID) and an RBW ID in a GC-DCI message to configure a UE115with a frequency slot format for full-duplex operation.

FIG.11illustrates an example of a process flow1100that supports RFIs in BWP management for full-duplex resource allocation in accordance with aspects of the present disclosure. In some examples, the process flow1100may implement aspects of the wireless communications systems100,200, or700. The process flow1100includes base station105-d, UE115-e, and UE115-f. These may be examples of the corresponding devices described with reference toFIGS.1through10. The UE115-eand/or base station105-dmay modify an operating (e.g., active) BWP and communicate based on the modified operating BWP. Alternative examples of the following may be implemented, where some steps are performed in a different order than described or are not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added.

At1105, UE115-emay communicate with base station105-dusing an operating BWP that includes a first set of frequency resources in a carrier bandwidth. In some cases, the operating BWP may be considered an active BWP, and in some additional or alternative cases, the operating BWP may be based on an RRC procedure. The operating BWP may include an active uplink BWP and an active downlink BWP.

At1110, UE115-emay receive a GC-DCI message that includes an RFI (e.g., an SFI) indicating a second set of resources. In some cases, UE115-fmay additionally receive the GC-DCI. For example, the GC-DCI message may be an example of UE group common signaling and may address one or more UEs115based on a slot format (SF) radio network temporary identifier (RNTI) (e.g., as part of the SlotFormatIndicator parameter structure). Each of the UEs115may decode the GC-DCI payload, but each UE115may extract the information relevant to that specific UE115. For example, UE115-emay identify one or more RFIs that correspond to UE115-ein the GC-DCI message (e.g., based on one or more positionInDCI values for UE115-eindicating one or more starting positions for information relevant to UE115-e). In some cases, the one or more RFIs may indicate a number of resource formats (e.g., an uplink format, a downlink format, a flexible format, or a full-duplex format) and a set of frequency resources (e.g., a slot frequency format, a BWP pair, or a BWP and an RBW). As such, the RFIs may support reconfiguring time resources, frequency resources, or both for flexible slots, flexible symbols, or both.

The number of bits corresponding to each RFI in the GC-DCI message may vary. For example, a UE115may extract from the DCI, for a single SFI, a number of bits based on the number of supported slot format combination IDs, the number of supported slot frequency format IDs, or a combination thereof. The UEs115may receive an indication of the actual size of the GC-DCI message, of the actual size of one or more RFIs in the GC-DCI message, or some combination thereof using a DCI-PayloadSize information element within a SlotFormatIndicator parameter structure. Using such information, UE115-emay determine the second set of frequency resources allocated for UE115-ein the GC-DCI message.

At1115, UE115-emay modify the operating BWP based on the second set of frequency resources. In some cases, UE115-emay modify the BWP by switching the operating BWP to the second set of frequency resources, while in some additional or alternative cases, UE115-emay modify the BWP by determining a set of overlapping frequency resources based on an overlap between the first set of frequency resources and the second set of frequency resources and reducing the operating BWP to the set of overlapping frequency resources.

At1120, UE115-emay communicate with base station105-dusing the modified BWP. In some case, UE115-emay communicate with base station105-dbased on a full-duplex mode, while in some additional or alternative cases, UE115-emay communicate with base station105-dbased on a full-duplex aware mode.
