DETAILED DESCRIPTION

In some wireless communications systems, a UE may communicate with a network entity using at least one BWP. As described herein, a BWP may refer to a contiguous set of one or more physical resource blocks (PRBs). In some cases, the network entity may configure the UE to switch from a first BWP to a second BWP if, for example, channel conditions associated with the first BWP deteriorate, or if the network entity determines that channel conditions associated with the second BWP are more favorable than channel conditions associated with the first BWP. The network entity may instruct the UE to switch from the first BWP to the second BWP by transmitting an instance of DCI to the UE. In some cases, however, if the network entity wants the UE to switch back to the first BWP (for example, if channel conditions associated with the first BWP improve relative to channel conditions associated with the second BWP), the network entity may have to transmit another instance of DCI to the UE, resulting in signaling overhead, processing latency, and extraneous power consumption.

The techniques and signaling mechanisms described herein support temporary BWP switching at a UE. In accordance with aspects of the present disclosure, the UE may receive an instance of DCI that indicates one or more parameters associated with a temporary BWP switch procedure. As described herein, a temporary BWP switch procedure may refer to the UE switching from a first (initial) BWP to a second (temporary) BWP and using the one or more parameters to communicate with a network entity via the second BWP. For example, the UE may transmit one or more uplink messages (in accordance with an uplink grant provided by the network entity) or receive one or more downlink messages (in accordance with downlink scheduling information provided by the network entity) using frequency resources associated with the second BWP. In some examples, the UE may switch back to the first BWP after monitoring the second BWP. In other examples, the UE may switch to a third (different) BWP after monitoring the second BWP.

The one or more parameters associated with the BWP switch may include, for example, an identifier of the second BWP, a time duration for the temporary BWP switch, a network antenna configuration, a transmit power configuration, a communication beam configuration, or a combination thereof. The time duration of the temporary BWP switch may be signaled as a quantity of symbols, slots, frames, or milliseconds. As described herein, the network antenna configuration may refer to a quantity of antenna ports used for downlink communications scheduled in the second (temporary) BWP, the transmit power configuration may indicate a transmit power used for downlink communications scheduled in the second BWP, and the communication beam configuration may indicate a set of one or more communication beams used for uplink or downlink communications scheduled in the second BWP.

The techniques and signaling mechanisms described herein may reduce the overall latency, power consumption, and signaling overhead associated with BWP switching operations in a wireless communications system. For example, the techniques described herein may enable a UE to perform multiple BWP switches based on a single instance of DCI from a network entity, as opposed to receiving one control message for each BWP switch. As a result, the network entity may transmit fewer control messages to the UE, which may result in greater power savings and reduced signaling overhead at the network entity. Moreover, the UE may allocate fewer processing resources to receiving and decoding control messages from the network entity, which may result in lower processing latency and reduced power consumption at the UE.

Aspects of the disclosure are initially described in the context of wireless communications systems, system architectures, resource diagrams, 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 BWP switching techniques for network power savings.

As described herein, a node of the wireless communications system100, which may be referred to as a network node, or a wireless node, may be a network entity105(e.g., any network entity described herein), a UE115(e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be a UE115. As another example, a node may be a network entity105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE115, the second node may be a network entity105, and the third node may be a UE115.

In another aspect of this example, the first node may be a UE115, the second node may be a network entity105, and the third node may be a network entity105. In yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE115, network entity105, apparatus, device, computing system, or the like may include disclosure of the UE115, network entity105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE115is configured to receive information from a network entity105also discloses that a first node is configured to receive information from a second node.

Consistent with this disclosure, once a specific example is broadened in accordance with this disclosure (e.g., a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node), the broader example of the narrower example may be interpreted in the reverse, but in a broad open-ended way. In the example above where a UE being configured to receive information from a base station also discloses that a first network node being configured to receive information from a second network node, the first network node may refer to a first UE, a first base station, a first apparatus, a first device, a first computing system, a first one or more components, a first processing entity, or the like configured to receive the information; and the second network node may refer to a second UE, a second base station, a second apparatus, a second device, a second computing system, a second one or more components, a second processing entity, or the like.

As described herein, communication of information (e.g., any information, signal, or the like) may be described in various aspects using different terminology. Disclosure of one communication term includes disclosure of other communication terms. For example, a first network node may be described as being configured to transmit information to a second network node. In this example and consistent with this disclosure, disclosure that the first network node is configured to transmit information to the second network node includes disclosure that the first network node is configured to provide, send, output, communicate, or transmit information to the second network node. Similarly, in this example and consistent with this disclosure, disclosure that the first network node is configured to transmit information to the second network node includes disclosure that the second network node is configured to receive, obtain, or decode the information that is provided, sent, output, communicated, or transmitted by the first network node.

In some examples, network entities105may communicate with the core network130, or with one another, or both. For example, network entities105may communicate with the core network130via one or more backhaul communication links120(e.g., in accordance with an S1, N2, N3, or other interface protocol). In some examples, network entities105may communicate with one another via a backhaul communication link120(e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network entities105) or indirectly (e.g., via a core network130).

In some examples, network entities105may communicate with one another via a midhaul communication link162(e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link168(e.g., in accordance with a fronthaul interface protocol), or any combination thereof. The backhaul communication links120, midhaul communication links162, or fronthaul communication links168may be or include one or more wired links (e.g., an electrical link, an optical fiber link), one or more wireless links (e.g., a radio link, a wireless optical link), among other examples or various combinations thereof. A UE115may communicate with the core network130via a communication link155.

In some examples, a network entity105may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture), which may be configured to utilize a protocol stack that is physically or logically distributed among two or more network entities105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, a network entity105may include one or more of a central unit (CU)160, a distributed unit (DU)165, a radio unit (RU)170, a RAN Intelligent Controller (RIC)175(e.g., a Near-Real Time RIC (Near-RT RIC), a Non-Real Time RIC (Non-RT RIC)), a Service Management and Orchestration (SMO)180system, or any combination thereof.

An RU170may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmission reception point (TRP). One or more components of the network entities105in a disaggregated RAN architecture may be co-located, or one or more components of the network entities105may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities105of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU), a virtual DU (VDU), a virtual RU (VRU)).

The split of functionality between a CU160, a DU165, and an RU170is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combinations thereof) are performed at a CU160, a DU165, or an RU170. For example, a functional split of a protocol stack may be employed between a CU160and a DU165such that the CU160may support one or more layers of the protocol stack and the DU165may support one or more different layers of the protocol stack. In some examples, the CU160may host upper protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., RRC, service data adaption protocol (SDAP), Packet Data Convergence Protocol (PDCP)).

The CU160may be connected to one or more DUs165or RUs170, and the one or more DUs165or RUs170may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU165and an RU170such that the DU165may support one or more layers of the protocol stack and the RU170may support one or more different layers of the protocol stack. The DU165may support one or multiple different cells (e.g., via one or more RUs170). In some cases, a functional split between a CU160and a DU165, or between a DU165and an RU170may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU160, a DU165, or an RU170, while other functions of the protocol layer are performed by a different one of the CU160, the DU165, or the RU170).

A CU160may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU160may be connected to one or more DUs165via a midhaul communication link162(e.g., F1, F1-c, F1-u), and a DU165may be connected to one or more RUs170via a fronthaul communication link168(e.g., open fronthaul (FH) interface). In some examples, a midhaul communication link162or a fronthaul communication link168may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities105that are in communication via such communication links.

In wireless communications systems (e.g., wireless communications system100), infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network130). In some cases, in an IAB network, one or more network entities105(e.g., IAB nodes104) may be partially controlled by each other. One or more IAB nodes104may be referred to as a donor entity or an IAB donor. One or more DUs165or one or more RUs170may be partially controlled by one or more CUs160associated with a donor network entity105(e.g., a donor base station140). The one or more donor network entities105(e.g., IAB donors) may be in communication with one or more additional network entities105(e.g., IAB nodes104) via supported access and backhaul links (e.g., backhaul communication links120).

IAB nodes104may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by DUs165of a coupled IAB donor. An IAB-MT may include an independent set of antennas for relay of communications with UEs115, or may share the same antennas (e.g., of an RU170) of an IAB node104used for access via the DU165of the IAB node104(e.g., referred to as virtual IAB-MT (vIAB-MT)). In some examples, the IAB nodes104may include DUs165that support communication links with additional entities (e.g., IAB nodes104, UEs115) within the relay chain or configuration of the access network (e.g., downstream). In such cases, one or more components of the disaggregated RAN architecture (e.g., one or more IAB nodes104or components of IAB nodes104) may be configured to operate according to the techniques described herein.

The UEs115and the network entities105may wirelessly communicate with one another via one or more communication links125(e.g., an access link) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined physical layer structure for supporting the communication links125. For example, a carrier used for a communication link125may include a portion of a RF spectrum band (e.g., a BWP) that is operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling that coordinates operation for the carrier, user data, or other signaling.

The wireless communications system100may support communication with a UE115using carrier aggregation or multi-carrier operation. A UE115may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity105and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network entity105. For example, the terms “transmitting,” “receiving,” or “communicating,” when referring to a network entity105, may refer to any portion of a network entity105(e.g., a base station140, a CU160, a DU165, a RU170) of a RAN communicating with another device (e.g., directly or via one or more other network entities105).

In some wireless communications systems that support cellular communications, network energy consumption may result in higher costs for network operators. A relatively large portion of network energy consumption may be attributed to RAN devices, such as AAUs that support massive MIMO communication schemes. Network energy saving features may be used to improve the efficiency and cost effectiveness of the wireless communications system100. The wireless communications system100may support network energy savings for various NR devices. For some base station energy consumption models, it may be desirable to enhance the power consumption modelling framework and evaluation methodology at the base station side, including relative energy consumption for downlink and uplink (considering factors like PA efficiency, number of transmitting RUs, base station load), sleep states and associated transition times, and other reference parameters and/or configurations.

The techniques described herein may support improved evaluation methodologies and corresponding KPIs. The evaluation methodologies disclosed herein may be used for evaluating system-level network energy consumption and energy savings gains, as well as for assessing and balancing the overall impact on network and user performance (e.g. spectral efficiency, capacity, UPT, latency, handover performance, call drop rate, initial access performance, SLA assurance-related KPIs), energy efficiency, UE power consumption, and UE complexity. The evaluation methodologies described herein may focus on multiple different KPIs, and may reuse existing KPIs (if applicable) in combination with other KPIs.

Aspects of the present disclosure may support techniques for improved network energy savings for network entities105and UEs115in terms of base station transmission and reception, which may enable such devices to attain greater efficiency (dynamically and/or semi-statically) and utilize more granular transmission/reception schemes that support network energy savings in time, frequency, space, or power, with potential support and/or feedback from UEs115, as well as potential UE assistance information. Additionally, or alternatively, the described techniques may support information exchange and/or coordination over network interfaces between communication devices in the wireless communications system100.

As illustrated in the example ofFIG.1, a UE115may include a communications manager101, which may be an example of the communications manager720described with reference toFIG.7. Likewise, a network entity105may include a communications manager102, which may be an example of a communications manager1120described with reference toFIG.11. The communications manager102may output a temporary BWP switching indication185for transmission to the UE115. The temporary BWP switching indication185may include one or more parameters associated with a procedure for a temporary BWP switch from a first (initial) BWP to a second (temporary) BWP.

Accordingly, the communications manager101may obtain the temporary BWP switching indication185from the network entity105and switch from the first BWP to the second BWP in accordance with the one or more parameters. In some examples, the communications manager102may output a downlink message for transmission to the UE115via time and frequency resources in the second BWP. Additionally, or alternatively, the communications manager101may output an uplink message for transmission to the network entity105via time and frequency resources in the second BWP. The UE115may, in some examples, switch from the second BWP to a third BWP after a time duration identified by the temporary BWP switching indication185.

FIG.2illustrates an example of a network architecture200(e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that supports BWP switching techniques for network power savings in accordance with one or more aspects of the present disclosure. The network architecture200may illustrate an example for implementing one or more aspects of the wireless communications system100. The network architecture200may include one or more CUs160-athat may communicate directly with a core network130-avia a backhaul communication link120-a, or indirectly with the core network130-athrough one or more disaggregated network entities105(e.g., a Near-RT RIC175-bvia an E2 link, or a Non-RT RIC175-aassociated with an SMO180-a(e.g., an SMO Framework), or both). A CU160-amay communicate with one or more DUs165-avia respective midhaul communication links162-a(e.g., an F1 interface). The DUs165-amay communicate with one or more RUs170-avia respective fronthaul communication links168-a. The RUs170-amay be associated with respective coverage areas110-aand may communicate with UEs115-avia one or more communication links125-a. In some implementations, a UE115-amay be simultaneously served by multiple RUs170-a.

Each of the network entities105of the network architecture200(e.g., CUs160-a, DUs165-a, RUs170-a, Non-RT RICs175-a, Near-RT RICs175-b, SMOs180-a, Open Clouds (O-Clouds)205, Open eNBs (O-eNBs)210) may include one or more interfaces or may be coupled with one or more interfaces configured to receive or transmit signals (e.g., data, information) via a wired or wireless transmission medium. Each network entity105, or an associated processor (e.g., controller) providing instructions to an interface of the network entity105, may be configured to communicate with one or more of the other network entities105via the transmission medium. For example, the network entities105may include a wired interface configured to receive or transmit signals over a wired transmission medium to one or more of the other network entities105. Additionally, or alternatively, the network entities105may include a wireless interface, which may include a receiver, a transmitter, or transceiver (e.g., an RF transceiver) configured to receive or transmit signals, or both, over a wireless transmission medium to one or more of the other network entities105.

In some examples, a CU160-amay host one or more higher layer control functions. Such control functions may include RRC, PDCP, SDAP, or the like. Each control function may be implemented with an interface configured to communicate signals with other control functions hosted by the CU160-a. A CU160-amay be configured to handle user plane functionality (e.g., CU-UP), control plane functionality (e.g., CU-CP), or a combination thereof. In some examples, a CU160-amay be logically split into one or more CU-UP units and one or more CU-CP units. A CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface, such as an E1 interface when implemented in an O-RAN configuration. A CU160-amay be implemented to communicate with a DU165-a, as necessary, for network control and signaling.

A DU165-amay correspond to a logical unit that includes one or more functions (e.g., base station functions, RAN functions) to control the operation of one or more RUs170-a. In some examples, a DU165-amay host, at least partially, one or more of an RLC layer, a MAC layer, and one or more aspects of a PHY layer (e.g., a high PHY layer, such as modules for FEC encoding and decoding, scrambling, modulation and demodulation, or the like) depending, at least in part, on a functional split, such as those defined by the 3rd Generation Partnership Project (3GPP). In some examples, a DU165-amay further host one or more low PHY layers. Each layer may be implemented with an interface configured to communicate signals with other layers hosted by the DU165-a, or with control functions hosted by a CU160-a.

In some examples, lower-layer functionality may be implemented by one or more RUs170-a. For example, an RU170-a, controlled by a DU165-a, may correspond to a logical node that hosts RF processing functions, or low-PHY layer functions (e.g., performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, or the like), or both, based at least in part on the functional split, such as a lower-layer functional split. In such an architecture, an RU170-amay be implemented to handle over the air (OTA) communication with one or more UEs115-a. In some implementations, real-time and non-real-time aspects of control and user plane communication with the RU(s)170-amay be controlled by the corresponding DU165-a. In some examples, such a configuration may enable a DU165-aand a CU160-ato be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

The SMO180-amay be configured to support RAN deployment and provisioning of non-virtualized and virtualized network entities105. For non-virtualized network entities105, the SMO180-amay be configured to support the deployment of dedicated physical resources for RAN coverage requirements which may be managed via an operations and maintenance interface (e.g., an O1 interface). For virtualized network entities105, the SMO180-amay be configured to interact with a cloud computing platform (e.g., an O-Cloud205) to perform network entity life cycle management (e.g., to instantiate virtualized network entities105) via a cloud computing platform interface (e.g., an O2 interface). Such virtualized network entities105can include, for example, CUs160-a, DUs165-a, RUs170-a, and Near-RT RICs175-b. In some implementations, the SMO180-amay communicate with components configured in accordance with a 4G RAN (e.g., via an O1 interface). Additionally, or alternatively, in some implementations, the SMO180-amay communicate directly with one or more RUs170-avia an O1 interface. The SMO180-aalso may include a Non-RT RIC175-aconfigured to support functionality of the SMO180-a.

The Non-RT RIC175-amay be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, Artificial Intelligence (AI) or Machine Learning (ML) workflows including model training and updates, or policy-based guidance of applications/features in the Near-RT RIC175-b. The Non-RT RIC175-amay be coupled to or communicate with (e.g., via an A1 interface) the Near-RT RIC175-b. The Near-RT RIC175-bmay be configured to include a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions over an interface (e.g., via an E2 interface) connecting one or more CUs160-a, one or more DUs165-a, or both, as well as an O-eNB210, with the Near-RT RIC175-b.

In some examples, to generate AI/ML models to be deployed in the Near-RT RIC175-b, the Non-RT RIC175-amay receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC175-band may be received at the SMO180-aor the Non-RT RIC175-afrom non-network data sources or from network functions. In some examples, the Non-RT RIC175-aor the Near-RT RIC175-bmay be configured to tune RAN behavior or performance. For example, the Non-RT RIC175-amay monitor long-term trends and patterns for performance and employ AI or ML models to perform corrective actions through the SMO180-a(e.g., reconfiguration via O1) or via generation of RAN management policies (e.g., A1 policies).

FIG.3illustrates an example of a wireless communications system300that supports BWP switching techniques for network power savings in accordance with one or more aspects of the present disclosure. The wireless communications system300may implement or be implemented by aspects of wireless communications system100or the network architecture200. For example, the wireless communications system300includes a UE115-b, which may be an example of a UE115, as described with reference toFIGS.1and2. The wireless communications system300also includes a network entity105-a, which may be an example of a network entity105described with reference toFIG.1. The network entity105-aand the UE115-bmay communicate within a coverage area110-b, which may be an example of a coverage area110described with reference toFIG.1. In the wireless communications system300, the UE115-bmay perform a temporary BWP switch according to one or more parameters305provided by the network entity105-aassociated with a temporary BWP switch procedure.

The network entity105-amay dynamically adjust settings and/or parameters used for communications with the UE115-b. One mechanism for dynamically changing these parameters, such as the number of CSI-RS ports, is through BWP switching. However, frequent BWP switching may increase the complexity and overhead of communications between the UE115-band the network entity105-a. In some cases, if the network entity105-aexperiences bursty traffic conditions, the network entity105-amay dynamically configure the UE115-bto switch from a first BWP to a second BWP, and may configure the UE115-bto switch back to the first BWP shortly thereafter. This may result in higher signaling overhead, as the UE115-breceives two separate BWP switching indications.

Rather than transmitting additional control messages to configure the UE115-bto revert back to the first BWP, aspects of the present disclosure may enable the network entity105-ato configure a procedure to perform a temporary BWP switch by the UE115-b, which may improve the signaling overhead and processing latency associated with BWP switching operations at the UE115-b. The described techniques may support mechanisms for temporary BWP switching and mechanisms for scheduling data transmissions in a temporary BWP, which may reduce the processing latency and signaling overhead of communications between the UE115-band the network entity105-a. Additionally, the techniques described herein may reduce the overall complexity of CSI reporting configurations for the UE115-b.

In some examples, it may be desirable to control antenna adaptation and power adaptation via BWP switching. In accordance with aspects of the present disclosure, the network entity105-amay send a physical downlink shared channel (PDSCH) transmission to the UE115-busing a second (temporary) BWP while remaining in a first BWP (such as a current active BWP of the network entity105-a) for other operations. More specifically, the network entity105-amay schedule a PDSCH transmission (such as a downlink message345) in a temporary BWP and configure the UE115-bto switch back to the previous BWP after receiving the scheduled PDSCH transmission. In some examples, the network entity105-amay be capable of signaling whether a BWP switch is temporary or persistent.

In some examples, to facilitate temporary BWP switching, the UE115-bmay transmit UE capability information355to the network entity105-a. The UE capability information355may indicate a capability of the UE115-bto support BWP temporary switching operations. The UE capability information355may identify a quantity of BWPs for which the UE115-bcan support temporary switching, which may be different from the total quantity of BWPs configured for the UE115-b. The UE capability information355may also indicate a minimum duration supported for temporary switching operations at the UE115-b.

The one or more parameters305provided by the network entity105-amay include, for example, a BWP switch duration310, a network antenna configuration315, a transmit power configuration320, a receive beam configuration325, and a transmit beam configuration330. The BWP switch duration310, if signaled, may indicate a quantity of frames, slots, symbols, or milliseconds for which the UE is to monitor a temporary BWP. The network antenna configuration315may indicate a quantity of antenna ports (such as CSI-RS antenna ports) the network entity105-aintends to use for transmission of a downlink message345. Likewise, the transmit power configuration320may indicate a transmit power the network entity105-aintends to use for transmission of the downlink message345.

The receive beam configuration325may, in some examples, indicate a quantity or orientation of communication beams to use for reception of the downlink message345from the network entity105-a. Likewise, the transmit beam configuration330may indicate a quantity or orientation of communication beams the network entity105-aintends to use for transmission of the downlink message345(e.g., a PDSCH transmission). In some examples, the downlink message345may include a DMRS sequence350that indicates whether a BWP switch is temporary or persistent. Additionally, or alternatively, the one or more parameters305may indicate one or more of a transmit power, a transmit beam configuration, or an antenna configuration to use for uplink communications scheduled in the temporary BWP.

In some examples, the network entity105-amay provide the UE115-bwith an uplink grant335to use for uplink communications in the temporary BWP. Accordingly, the UE115-bmay transmit an uplink message360using physical uplink shared channel (PUSCH) resources indicated by the uplink grant335. Additionally, or alternatively, the network entity105-amay transmit downlink scheduling information340to the UE115-b. The UE115-bmay, in some examples, receive the downlink message345via PDSCH resources indicated by the downlink scheduling information340. After transmitting the uplink message360(in accordance with the uplink grant335) or receiving the downlink message345(in accordance with the downlink scheduling information340), the UE115-bmay, in some examples, switch back to the first (initial) BWP or switch to a third BWP that is different from the first BWP.

FIG.4illustrates an example of a resource diagram400that supports BWP switching techniques for network power savings in accordance with one or more aspects of the present disclosure. The resource diagram400may implement or be implemented by aspects of any of the wireless communications systems or system architectures described with reference toFIGS.1through3. For example, the resource diagram400may be implemented by a UE, such as the UE115-bdescribed with reference toFIG.3. In the example ofFIG.4, the UE may receive an instruction to temporarily switch from a BWP405to a BWP410for a time duration. Accordingly, the UE may switch to the BWP410(a temporary BWP) and communicate with a network entity (such as the network entity105-adescribed with reference toFIG.3) for the specified time duration. In some examples, the UE may switch back to the BWP405after the time duration has elapsed. In other examples, the UE may switch to a BWP415after the time duration has elapsed.

As described herein with reference toFIGS.1through3, the UE may receive an indication of one or more parameters (such as the parameters305described with reference toFIG.3) for a temporary BWP switch from the BWP405(BWP1) to the BWP410(BWP2). The one or more parameters associated with a temporary BWP switch procedure may indicate a time duration for the temporary BWP switch, a network antenna configuration for the BWP410, a transmit power for a PDSCH transmission scheduled in the BWP410, a receive beam to use for reception of the PDSCH transmission, a transmit beam used for the PDSCH transmission, or a combination thereof. In some examples, the UE may also receive an uplink grant indicating one or more PUSCH resources to use for an uplink transmission in the BWP410.

Accordingly, the UE may receive a downlink message from the network entity via PDSCH resources in the BWP410and/or transmit an uplink message to the network entity via PUSCH resources in the BWP410after switching from the BWP405to the BWP410in accordance with the one or more parameters associated with the temporary BWP switch procedure. The UE may switch back to the BWP405or switch to the BWP415(BWP3) after performing all scheduled communications or after a time duration of the temporary BWP switch has elapsed. The UE may determine whether to switch back to the BWP405, continue monitoring the BWP410, or switch to the BWP415based on a DCI indication from the network entity, an RRC configuration associated with the BWP410, a DMRS sequence in a PDSCH transmission from the network entity, an MCS associated with the PDSCH transmission, an FDRA associated with the PDSCH transmission, a TDRA associated with the PDSCH transmission, a number of layers used for the PDSCH transmission, or a combination thereof.

The network entity may instruct the UE to switch from the BWP405to the BWP410for one or more symbols, slots, frames, or milliseconds. In some examples, this instruction may be signaled in an RRC configuration for the BWP410. In other examples, this instruction may be conveyed to the UE via dynamic signaling, such as a DCI message or a MAC-control element (MAC-CE). Additionally, or alternatively, the UE may receive an indication of whether the BWP410is a temporary BWP. In other words, if the BWP410is configured as a temporary BWP and the UE receives an indication to switch to the BWP410(for example, while monitoring the BWP405), the UE may switch back to the BWP405or switch to the BWP415(another RRC-configured BWP) after a time duration (for example, the BWP switch duration310described with reference toFIG.3) specified in the RRC configuration for the BWP410.

A temporary BWP switching indication (transmitted by means of a DCI message or a MAC-CE) may provide the UE with a time duration of the temporary BWP switch. Thus, in some examples, the UE may determine whether a BWP switch is temporary or persistent based on whether the UE receives an indication of a time duration for the BWP switch. If, for example, the temporary BWP switching indication is signaled to the UE via DCI, a quantity of bits (for example, two bits) in the DCI may correspond to an entry of an RRC-configured table that identifies whether a BWP is temporary and/or a temporary BWP switch duration. For example, a value of 00 may indicate that a BWP switch is persistent, a value of 01 may indicate a temporary BWP switch duration of 4 slots, a value of 10 may indicate a temporary BWP switch duration of 8 slots, and a value of 11 may indicate a temporary BWP switch duration of 20 slots.

Although the temporary BWP switching mechanisms disclosed herein are illustrated and described in the context of uplink and downlink communications between a UE and a network entity (for example, over a Uu communication link), it is to be understood that aspects of the present disclosure are also applicable to sidelink communications between two UEs (for example, over a PC5 communication link) and/or PC5-based UE-to-network relay scenarios in which a first UE serves as a relay device between a second UE and a network entity. In such examples, a sidelink UE may receive a temporary BWP switching indication via an instance of sidelink control information (SCI) from another sidelink UE.

Thus, in some cases, a temporary BWP switching indication may be applicable to sidelink communications between two UEs. For example, a first sidelink UE may receive, via the BWP405(BWP1), an indication of one or more parameters associated with a temporary BWP switch procedure, where the one or more parameters are to be used for sidelink communications between the first sidelink UE and a second sidelink UE in the BWP410(BWP2). The first sidelink UE may receive the indication from the second sidelink UE (for example, over a PC5 connection) or from a network entity (for example, over a Uu interface). Accordingly, the first sidelink UE may switch from the BWP405to the BWP410and use the one or more parameters to perform sidelink communications with the second sidelink UE via resources in the BWP410. In some examples, the first sidelink UE may switch back to the BWP405after a time duration and continue communicating with the second sidelink UE via resources in the BWP405. In other examples, the first sidelink UE may switch to the BWP415(BWP3) and perform sidelink communications with the second sidelink UE via resources in the BWP415.

One or more aspects of the resource diagram400may support techniques for reducing the overall latency, power consumption, and signaling overhead of BWP switching operations at the UE. For example, the techniques and signaling mechanisms described with reference toFIG.4may enable the UE to perform multiple BWP switches based on a single instance of DCI from the network entity, as opposed to the network entity transmitting another instance of DCI for each subsequent BWP switch. As a result, the network entity may transmit fewer control messages to the UE, which may result in greater power savings and reduced signaling overhead at the network entity. Moreover, the UE may allocate fewer processing resources to receiving and decoding control messages from the network entity, which may result in lower processing latency and reduced power consumption at the UE.

FIG.5illustrates an example of a resource diagram500that supports BWP switching techniques for network power savings in accordance with one or more aspects of the present disclosure. The resource diagram500may implement or be implemented by aspects of any of the wireless communications systems, network architectures, or resource diagrams described with reference toFIGS.1through4. For example, the resource diagram500includes a BWP505(BWP1), which may be an example of the BWP405described with reference toFIG.4. The resource diagram500also includes a BWP510(BWP2), which may be an example of the BWP410described with reference toFIG.4. In the example ofFIG.5, a UE (such as the UE115-bdescribed with reference toFIG.3) may receive a PDSCH transmission from a network entity (such as the network entity105-adescribed with reference toFIG.3) after switching from the BWP505to the BWP510in accordance with any of the temporary BWP switching procedures discussed inFIGS.1through4. In some cases, the UE115-bmay be preconfigured with a particular temporary BWP switching procedure to use, or the network entity105-amay signal which temporary BWP switching procedure that the UE115-bis to apply.

As described herein with reference toFIGS.1through4, which include examples of temporary BWP switching procedures, the UE may receive an indication of one or more parameters (such as the parameters305described with reference toFIG.3) to use for a temporary BWP switch from the BWP505to the BWP510. The one or more parameters may include a time duration540for the temporary BWP switch, a network antenna configuration for the BWP510, a transmit power for a PDSCH transmission530scheduled in the BWP510, a receive beam to use for reception of the PDSCH transmission530, a transmit beam used for the PDSCH transmission530, or a combination thereof. Accordingly, the UE may receive the PDSCH transmission530from the network entity via the BWP510after switching from the BWP505to the BWP510during a switching gap525. In some examples, the UE may switch back to the BWP505during a switching gap535after receiving the PDSCH transmission530from the network entity or after the time duration540has elapsed.

The network entity may configure the UE to temporarily switch from the BWP505to the BWP510if, for example, channel conditions (such as SINR, RSRP, CQI, RSSI) associated with the BWP505deteriorate or if channel conditions associated with the BWP510improve relative to the channel conditions associated with the BWP505. Additionally, or alternatively, the network entity may configure the UE to temporarily switch from the BWP505to the BWP510such that the network entity can transmit a PDSCH transmission530to the UE and/or receive a PUSCH transmission from the UE via the BWP510. The network entity may configure temporary BWP switching behaviors for the UE using a combination of semi-static signaling (such as an RRC message515) and dynamic signaling (such as a DCI message or a MAC-CE).

Any BWP can be a temporary BWP if the network entity designates the BWP as a temporary BWP. In some examples, an instance of DCI520may include an instruction to switch from the BWP505to the BWP510and/or an indication that a switch from the BWP505to the BWP510is temporary. In some examples, the network entity may indicate whether a BWP switch is temporary using a reserved bit or an extra bit in the instance of DCI520. The bit used to signal the temporary BWP switching indication may, in some examples, be toggled by the network entity. For example, the network entity may indicate a temporary BWP switch by toggling a DCI bit from a first value (0) to a second value (1). Additionally, or alternatively, the network entity may automatically trigger a temporary BWP switch for the UE by setting a DCI bit to a specific value. In other examples, the network entity may indicate whether a BWP switch is temporary via a DMRS sequence in the PDSCH transmission530scheduled in the BWP510. Upon detecting the DMRS sequence in the PDSCH transmission530, the UE may determine that the BWP510is a temporary BWP and/or that the UE is to switch back to the BWP505after receiving the PDSCH transmission530.

The time duration540of the BWP switch (if temporary) may be RRC-configured per BWP or per cell. Thus, the time duration540for which the UE monitors the BWP510may be specific to an RRC configuration of the BWP510. In some examples, the UE may determine that a BWP switch is temporary if the PDSCH transmission530(a downlink message) is scheduled with specific RRC-configured parameters. For example, if the UE receives an indication to switch from the BWP505to the BWP510such that the UE can receive the PDSCH transmission530, the UE may implicitly determine that the BWP switch is temporary based on an MCS, a number of layers, a TDRA value, or an FDRA value associated with the PDSCH transmission530. A duration of the BWP switch may be based on various factors, such as MCS, number of layers, TDRA, FDRA, DCI indication, DMRS sequence, RRC configuration, etc.

One or more aspects of the resource diagram500may support techniques for reducing the overall latency, power consumption, and signaling overhead of BWP switching operations at the UE. For example, the techniques and signaling mechanisms described with reference toFIG.5may enable the UE to perform multiple BWP switches based on a single instance of DCI520from the network entity, as opposed to the network entity transmitting another instance of DCI520for each subsequent BWP switch. As a result, the network entity may transmit fewer control messages to the UE, which may result in greater power savings and reduced signaling overhead at the network entity. Moreover, the UE may allocate fewer processing resources to receiving and decoding control messages from the network entity, which may result in lower processing latency and reduced power consumption at the UE.

FIG.6illustrates an example of a process flow600that supports BWP switching techniques for network power savings in accordance with one or more aspects of the present disclosure. The process flow600may implement or be implemented by aspects of any of the wireless communications systems, network architectures, or resource diagrams described with reference toFIGS.1through5. For example, the process flow600includes a UE115-c, which may be an example of a UE115, as described herein with reference toFIGS.1through5. The process flow600also includes a network entity105-b, which may be an example of a network entity105, as described herein with reference toFIGS.1through5. In the following description of the process flow600, operations between the UE115-cand the network entity105-bmay be added, omitted, or performed in a different order (with respect to the exemplary order shown).

At605, the UE115-cmay transmit UE capability information (for example, the UE capability information355described with reference toFIG.3) to the network entity105-b. The UE capability information may indicate whether the UE115-csupports temporary BWP switching and, if so, a number of BWPs for which the UE115-ccan support temporary BWP switching, which may be the same or different from a number of BWPs configured for the UE115-c. The UE capability information may also indicate a shortest time duration supported by the UE115-cfor temporary BWP switching. The UE115-cmay signal the UE capability information to the network entity105-bvia one or more RRC IEs.

At610, the UE115-cmay receive RRC signaling from the network entity105-b. The RRC signaling may indicate respective configurations for one or more BWPs supported by the UE115-cfor a temporary BWP switch procedure. For example, the RRC signaling may indicate a first configuration for a first BWP supported by the UE115-cand a second configuration for a second BWP supported by the UE115-c. The first configuration may include an identifier of the first BWP, a frequency range associated with the first BWP, locations of different channels (such as uplink shared channels or downlink control channels) within the first BWP, etc. Likewise, the second configuration may include an identifier of the second BWP, a frequency range associated with the second BWP, and locations of different channels (for example, uplink control channels, downlink shared channels) in the second BWP. In some examples, the second configuration may indicate that the second BWP is a temporary BWP. If the second BWP is configured as a temporary BWP, the second configuration may also indicate a time duration for which to monitor the second (temporary) BWP.

At615, the UE115-cmay receive an instance of DCI (such as the DCI520described with reference toFIG.5) from the network entity105-b. The instance of DCI may indicate a temporary BWP switching command (also referred to herein as a temporary BWP switching indication) for the UE115-c. In some examples, one or more bits in the DCI may correspond to an index of an RRC-configured table that includes a list of possible BWP switching parameters. Accordingly, the UE115-cmay determine one or more BWP switching parameters (for example, a target BWP, a time duration, antenna information) for the temporary BWP switch procedure for the UE115-cto use based on the one or more bits signaled in the DCI. In some examples, the instance of DCI may include downlink scheduling information (for example, the downlink scheduling information340described with reference toFIG.4) that schedules a PDSCH transmission for the UE115-cin the second BWP.

At620, the UE115-cmay switch from the first BWP (for example, the BWP405described with reference toFIG.4) to the second BWP (for example, the BWP410described with reference toFIG.4) in accordance with the temporary BWP switching command from the network entity105-b. In some examples, the UE115-cmay determine that a switch from the first BWP to the second BWP is temporary based on an RRC configuration of the second BWP (for example, if the second BWP is configured as a temporary BWP), an MCS associated with a PDSCH transmission scheduled in the second BWP, an FDRA index associated with a PDSCH transmission scheduled in the second BWP, a number of layers associated with a PDSCH transmission scheduled in the second BWP, a DCI indication from the network entity105-b, or a combination thereof.

At625, the UE115-cmay, in some examples, receive a PDSCH transmission (such as the downlink message345described with reference toFIG.3) from the network entity105-bvia a set of time and frequency resources in the second BWP.

In some implementations, the one or more interfaces may refer to an interface between the processing system of the chip or modem and a transmitter, such that the device1405may transmit information output from the chip or modem. Additionally, or alternatively, in some implementations, the one or more interfaces may refer to an interface between the processing system of the chip or modem and a receiver, such that the device1405may obtain information or signal inputs, and the information may be passed to the processing system. A person having ordinary skill in the art will readily recognize that a first interface also may obtain information or signal inputs, and a second interface also may output information or signal outputs.

The communications manager1420may be configured as or otherwise support a means for communicating via a third BWP based on a switch from the second BWP to the third BWP in accordance with the one or more parameters associated with the temporary BWP switch procedure.

By including or configuring the communications manager1420in accordance with examples as described herein, the device1405may support techniques for reduced processing latency and lower signaling overhead by enabling the device1405to configure multiple BWP switches with a single instance of DCI, as opposed to the device1405transmitting an instance of DCI for each BWP switch. As a result, the device1405may transmit fewer control messages to the UE, which may result in greater power savings and reduced signaling overhead at the device1405.

In some examples, the communications manager1420may be configured to perform various operations (e.g., receiving, obtaining, monitoring, outputting, transmitting) using or otherwise in cooperation with the transceiver1410, the one or more antennas1415(e.g., where applicable), or any combination thereof. Although the communications manager1420is illustrated as a separate component, in some examples, one or more functions described with reference to the communications manager1420may be supported by or performed by the transceiver1410, the processor1435, the memory1425, the code1430, or any combination thereof. For example, the code1430may include instructions executable by the processor1435to cause the device1405to perform various aspects of BWP switching techniques for network power savings as described herein, or the processor1435and the memory1425may be otherwise configured to perform or support such operations.
