TECHNIQUES FOR PERFORMING UPLINK CONTROL CHANNEL BEAM HOPPING AND REPETITION

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a message scheduling transmission, by the UE, of uplink control information (UCI) in an uplink control channel resource, such as a physical uplink control channel (PUCCH) resource. The UE may receive an indication that the UE is scheduled to transmit the UCI via a first beam during the uplink control channel resource and via a second beam during the uplink control channel resource, where the first beam may be directed to a first base station and the second beam may be directed to a second base station. The UE may determine a number of repetitions associated with transmitting the UCI, and transmit the UCI via one of inter-slot repetition, intra-uplink control channel resource beam hopping, or intra-slot repetition based on the number of repetitions.

TECHNICAL FIELD

The following relates to wireless communications, including techniques for performing uplink control channel beam hopping and repetition.

BACKGROUND

In some wireless communications systems, a UE may be configured to transmit an uplink transmission, such as a transmission including uplink control information (UCI). In some cases, the UE may be configured to transmit the uplink transmission via multiple beams, such as to transmit the uplink transmission to multiple base stations. Conventional techniques for configuring the UE to transmit the uplink transmission via multiple beams may be improved.

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support techniques for performing uplink control channel beam hopping and repetition. Generally, the described techniques provide for enhanced methods for configuring a user equipment (UE) to transmit uplink transmissions via multiple beams. A UE may receive, from a base station, a message scheduling transmission, by the UE, of an uplink transmission such as a transmission including uplink control information (UCI) in an uplink control channel resource (e.g., a physical uplink control channel (PUCCH) resource). The UE may receive an indication that the UE is scheduled to transmit the UCI via a first beam during the PUCCH resource and via a second beam during the PUCCH resource, where the first beam may be directed to a first base station and the second beam may be directed to a second base station, or the first beam and the second beam may be directed to the same base station. The UCI transmitted via the first beam and the UCI transmitted via the second beam may be the same or similar. The UE may determine a number of repetitions associated with transmitting the UCI. For example, the UE may determine whether the UE is configured to transmit the UCI via the first beam and the second beam in one PUCCH resource of one slot or sub-slot or in multiple slots of sub-slots. If the UE is configured to transmit the UCI via the first beam and the second beam in multiple slots or sub-slots, the UE may be configured with a number of repetitions greater than one. If the UE is configured to transmit the UCI in one slot or sub-slot, the UE may be configured with a number of repetitions equal to one (e.g., no repetitions). The UE may transmit the UCI via one of intra-PUCCH resource beam hopping (e.g., with repetitions or without repetitions), intra-slot repetition, or inter-slot repetition based on the number of repetitions.

The method may include receiving, from a base station, a message scheduling transmission, by the UE, of UCI in an uplink control channel resource, receiving an indication that the UE is scheduled to transmit the UCI via a first beam during the uplink control channel resource and via a second beam during the uplink control channel resource, determining a number of repetitions associated with transmitting the UCI, and transmitting the UCI via one of inter-slot repetition, intra-uplink control channel resource beam hopping, or intra-slot repetition based on the number of repetitions.

DETAILED DESCRIPTION

A wireless communications system may include various communication devices such as a user equipment (UE) and a base station, which may provide wireless communication services to the UE. In the wireless communications system, the UE may be configured to transmit one or more uplink transmissions to one or more base stations. For example, the UE may transmit an uplink transmission carrying uplink control information (UCI) to support various uplink operations (e.g., uplink transmissions, downlink reception). For example, the UCI may, in some examples, convey various information including feedback information (e.g., hybrid automatic repeat request acknowledgment (HARQ-ACK), scheduling information (e.g., scheduling requests (SR)), or channel information (e.g., channel state information (CSI)). The UE may encode and transmit one or more UCIs on an uplink channel, such as a physical uplink control channel (PUCCH). In some cases, the UE may be configured to transmit the one or more UCIs on allocated resources such as a PUCCH resource, where a PUCCH resource may refer to a set of allocated time and frequency resources, such as within a slot or sub-slot, on a PUCCH. As such, a PUCCH resource in a first slot and a PUCCH resource in a second slot that are allocated the same time and frequency resources may be referred to as the same PUCCH resource.

In some implementations, multiple beams (e.g., spatial relation informations) may be activated per PUCCH resource such that a UE may transmit an uplink transmission within a PUCCH resource via multiple beams (e.g., in one slot or sub-slot, or multiple slots or sub-slots), where each beam of the multiple beams may be directed to a different base station (e.g., base station, transmission reception point (TRP), node). For example, the UE may transmit the same UCI to different base stations via different beams so as to improve reliability of the UE's communications with one or more of the base stations. To support a UE transmitting an uplink transmission to multiple base stations (e.g., multi-TRP PUCCH transmission), the UE may be configured to transmit the uplink transmission in accordance with intra-PUCCH resource beam hopping, intra-slot repetition, or inter-slot repetition. Repetition may refer to transmitting the same (or similar) set of information (e.g., bits) multiple times, and thus, the set of information is repeated. For example, two repetitions may each carry the same set of information, such that the set of information may be transmitted via a first beam and the same set of information may be transmitted via the second beam. Beam hopping uses one set of information (e.g., bits), where a subset of the information is transmitted via the first beam and a second subset of the information is transmitted via the second beam.

As such, intra-PUCCH resource beam hopping may refer to a UE transmitting UCI via two different beams in the same PUCCH resource, where the UE may transmit UCI via a first beam in a first portion (e.g., a first set of symbols) of the PUCCH resource and transmit UCI in a second beam in a second portion (e.g., a second set of symbols) of the PUCCH resource. Intra-slot repetition may refer to a UE transmitting UCI via two different beams in a PUCCH resource in two different sub-slots of a slot, where the UE may transmit UCI via a first beam in a PUCCH resource of a first sub-slot and transmit UCI via a second beam in the PUCCH resource of a second sub-slot. The PUCCH resource used in the first sub-slot and the second sub-slot may be the same PUCCH resource. As the UE is configured to transmit the same UCI in a PUCCH resource in two different sub-slots, the UCI transmitted in the second sub-slot may be repeated UCI of the UCI transmitted in the first sub-slot. Inter-slot repetition may refer to a UE transmitting UCI via two different beams in a PUCCH resource in two different slots, where the UE may transmit UCI via a first beam in a PUCCH resource of a first slot and transmit UCI via a second beam in the PUCCH resource of a second slot. The PUCCH resource used in the first slot and the second slot may be the same PUCCH resource. As the UE is configured to transmit the same UCI in a PUCCH resource in two different slots, the UCI transmitted in the second slot may be repeated UCI of the UCI transmitted in the first slot.

In some implementations, a UE may receive information for transmitting the UCI that may implicitly or explicitly indicate that the UE transmits the UCI in accordance with intra-PUCCH resource beam hopping, intra-slot repetition, or inter-slot repetition. For example, the information may indicate a number of repetitions associated with transmitting the UCI, where the number of repetitions may be indicated for slots or sub-slots. For example, the UE may be triggered to perform inter-slot repetition if the number of repetitions in relation to slots is greater than one so as to allow the UE to transmit repeated UCI in a PUCCH resource in two different slots. In another example, the UE may be triggered to perform intra-slot repetition if the number of repetitions in relation to sub-slots is greater than one so as to allow the UE to transmit repeated UCI in a PUCCH resource in two different sub-slots, such that the UE may perform repetitions within a slot. In another example, the UE may be triggered to perform intra-PUCCH resource beam hopping if the number of repetitions is equal to one (e.g., no repetition), or if the UE did not receive an indication of a number of repetitions because the UE may transmit the UCI within one PUCCH resource.

However, in some implementations, intra-PUCCH resource beam hopping with repetitions in which the UE may perform intra-PUCCH resource beam hopping in multiple slots (e.g., or sub-slots) may be a beneficial transmission configuration. For example, the UE may transmit UCI via a first beam in a first portion of a PUCCH resource and transmit UCI via a second beam in a second portion of a PUCCH resource in a first slot and the UE may transmit according to the same configuration in a second slot, or third slot. Conventional methods for distinguishing between intra-PUCCH resource beam hopping with repetitions, intra-slot repetition, and inter-slot repetition may be improved. The UE may receive an indication to transmit UCI via multiple beams in accordance with multiple repetitions. To distinguish between intra-PUCCH resource beam hopping with repetitions, intra-slot repetition, and inter-slot repetition, the UE, in some cases, may receive an indication (e.g., in radio resource control (RRC) or medium access control (MAC) control element (CE)) of whether to transmit the UCI in accordance with intra-PUCCH resource beam hopping with repetitions, inter-slot repetition, or intra-slot repetition. In some cases, the UE may be configured to perform intra-PUCCH resource beam hopping with repetitions based on the type of UCI the UE is configured to transmit, or based on a payload size of the UCI the UE is configured to transmit. In some implementations, the option for the UE to perform intra-PUCCH resource beam hopping with repetitions by be turned off, or the UE may otherwise not be configured to perform intra-PUCCH resource beam hopping with repetitions. In such cases, if the UE receives an indication that the number of repetitions is greater than one (e.g., for slots, or sub-slots), then the UE may default to inter-slot repetition, or intra-slot repetition, accordingly. If a number of repetitions is not configured, or if the number of repetitions is equal to one, then the UE may default to intra-PUCCH resource beam hopping (without repetitions).

Particular aspects of the subject matter described herein may be implemented to realize one or more advantages. The described techniques may support improvements in indicating to a UE a UCI transmission configuration by improving reliability and clarity, among other advantages. As such, supported techniques may include improved network operations and, in some examples, may promote network efficiencies, among other benefits.

Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects are then described with reference to transmission configurations and a process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques for performing uplink control channel beam hopping and repetition.

In some wireless communications systems, such as wireless communications system100, a UE115may receive, from a base station105, a message scheduling transmission, by the UE115, of an uplink transmission such as a transmission including UCI in an uplink control channel resource (e.g., a PUCCH resource). The UE115may receive an indication that the UE115is scheduled to transmit the UCI via a first beam during the PUCCH resource and via a second beam during the PUCCH resource (e.g., in one PUCCH resource, in repeated PUCCH resources in multiple slots, or in repeated PUCCH resources in multiple sub-slots), where the first beam may be directed to a first base station and the second beam may be directed to a second base station, or the first beam and the second beam may be directed to the same base station. The UCI transmitted via the first beam and the UCI transmitted via the second beam may be the same or similar. The UE115may determine a number of repetitions associated with transmitting the UCI. For example, the UE115may determine whether the UE115is configured to transmit the UCI via the first beam and the second beam in one PUCCH resource or multiple. If the UE115is configured to transmit the UCI via the first beam and the second beam in multiple PUCCH resources (e.g., multiple repeated PUCCH resources in multiple slots or sub-slots), the UE115may be configured with a number of repetitions greater than one. If the UE115is configured to transmit the UCI in one PUCCH resource (e.g., in one slot or sub-slot), the UE115may be configured with a number of repetitions equal to one (e.g., no repetitions). The UE115may transmit the UCI via one of intra-PUCCH resource beam hopping (e.g., with repetitions or without repetitions), intra-slot repetition, or inter-slot repetition based on the number of repetitions.

FIG. 2illustrates an example of a wireless communications system200that supports techniques for performing uplink control channel beam hopping and repetition in accordance with aspects of the present disclosure. The wireless communications system200may include base stations105-aand105-band UE115-a, which may be examples of base stations105and a UE115as described with reference toFIG. 1. Base station105-aand base station105-bmay each serve a geographic coverage area, that may be the same, partially the same, or different from one another. In some cases, UE115-amay be configured to perform a UCI transmission procedure in which UE115-amay transmit UCI via one or more beams215. Additionally or alternatively, other wireless devices, such as base station105-aand/or base station105-bmay indicate a UCI transmission configuration and or receive the UCI transmission from UE115-a.

In some implementations, a UE115may communicate with a serving base station105of the UE115and/or communicate with one or more other base stations105, such as neighboring base stations105to the UE115. A base station105as described herein may refer to a TRP, integrated access and backhaul (IAB) node, or a wireless device. For example, UE115-aand base station105-amay be in communications with one another, where base station105-amay be a serving base station105of UE115-a. UE115-amay receive one or more signals from base station105-avia communication link205-a, which may be a downlink communications link. In some cases, UE115-amay transmit one or more signals to base station105-avia communication link210-a, which may be an uplink communications link. Additionally or alternatively, UE115-amay transmit one or more signals to base station105-b(e.g., a neighboring base station105, a base station105near UE115-a) via communication link210-b, which may be an uplink communications link. For example, UE115-amay receive an uplink channel configuration220from base station105-athat may configure UE115-ato transmit one or more uplink transmissions225(e.g., UCI) via one or more beams in one or more uplink resources. For example, base station105-amay configure UE115-ato transmit UCI in a PUCCH resource via a first beam215-adirected to base station105-aand via a second beam215-bdirected to base station105-bin accordance with intra-PUCCH resource beam hopping (e.g., with or without repetition), inter-slot repetition, or intra-slot beaming hopping. In some cases, UE115-amay receive an uplink channel configuration220from base station105-bthat may configure UE115-ato transmit one or more uplink transmissions225(e.g., UCI) via one or more beams in one or more uplink resources.

For example, a UE115may transmit an uplink transmission carrying UCI to support various uplink operations (e.g., uplink transmissions, downlink reception). The UCI may, in some examples, convey various information including feedback information (e.g., HARQ-ACK, scheduling information (e.g., an SR), channel information (e.g., CSI). The UE115may encode and transmit one or more UCIs on an uplink channel, such as a PUCCH. In some cases, the UE115may be configured to transmit the one or more UCIs on allocated resources such as a PUCCH resource, where a PUCCH resource may refer to a set of allocated time and frequency resources on a PUCCH, such as within a slot, or sub-slot. As such, a PUCCH resource in a first slot and a PUCCH resource in a second slot that are allocated the same time and frequency resources may be referred to as the same PUCCH resource. In some implementations, a UE115may be configured to support PUCCH repetition in different slots, or sub-slots in which the UE115may transmit uplink information in a PUCCH resource of a first slot (or sub-slot), and may repeat and transmit the uplink information in the same PUCCH resource in a second slot (or sub-slot), and so on. PUCCH repetition (e.g., a number of repetitions, slot repetition, sub-slot repetition) may be configured for certain PUCCH formats, such as PUCCH formats 1, 3, and 4. As such, for at least PUCCH formats 1, 3, or 4, a UE115may be configured a number of slots (or sub-slots) for repetitions of a PUCCH transmission. The number of repetitions (e.g., number of slots, number of sub-slots) may be configured per PUCCH format, and may be configured via a radio resource control (RRC) configuration. For example, RRC signaling may include a field that indicates a number of slots (e.g., nrofSlots) for PUCCH format 1, PUCCH format 3, or PUCCH format 4, or a combination thereof, where the number of slots configured for each PUCCH format may be the same or different. The number of slots field may indicate any number greater than zero, such as 1 (e.g., no repetition), 2, 4, 8, where the number of slots is equal to the number of repetitions (e.g., nrofSlots=N repeat). For example, PUCCH format 1 may be allocated a number of slots equal to two, PUCCH format 3 may be allocated a number of slots equal to four, and PUCCH format 4 may be allocated a number of slots equal to eight. In some cases, PUCCH repetition (e.g., a number of repetitions, slot repetition, sub-slot repetition) may be configured per PUCCH resource, rather than PUCCH format.

If the UE115is configured to transmit an uplink transmission in a PUCCH resource that has been allocated a number of n slots, the UE115may transmit the uplink transmission in a PUCCH resource repetition in n slots (e.g., the PUCCH resource is repeated n times). For example, UE115-amay be configured to transmit an uplink transmission in a PUCCH resource configured as PUCCH format 1. As such, UE115-amay transmit the uplink transmission in the PUCCH resource in a first slot, and transmit the same, repeated uplink transmission in the PUCCH resource in a second slot.

In some implementations, the UE115may transmit the repeated uplink transmission using one beam215, or multiple beams215. For example, a UE115may be configured with one or more activated beams215(e.g., activated spatial relation informations) per PUCCH resource, such that the UE115may be enabled to transmit the same PUCCH transmission of the same UCI via multiple beams215, where each beam215of the multiple beams215may be directed at different base stations105(e.g., TRPs) so as to improve reliability of the network. In some cases, UE115-amay receive the indication of the activated beams215(e.g., the multiple activated beams215) via a MAC-CE message. The indication may implicitly or explicitly indicate a number of activated beams215, and/or the identity of the activated beams215. For example, UE115-amay receive an indication to transmit UCI in a PUCCH resource that is configured with or without repetitions, and UE115-amay receive an indication that multiple beams215, such as two beams215, are activated for that PUCCH resource. As such, UE115-amay be configured to transmit the UCI in the PUCCH resource (in one or more slots, or sub-slots) via a first beam215-adirected to base station105-aand via a second beams215-bdirected to base station105-b. In some cases, UE115-amay transmit the UCI via the first beam215-aat a first transmission power, and transmit the UCI via a second beam215-bat a second transmission power, where the first transmission power and the second transmission power may be the same or different. The examples described herein may describe a UE115transmitting UCI in a PUCCH resource via two beams215, although, the UE115may be configured to transmit any uplink transmission in a PUCCH resource (e.g., not limited to UCI) via any number of beams215(e.g., not limited to two beams215).

To support UE115-atransmitting a PUCCH transmission (e.g., UCI) via multiple beams (e.g., multi-TRP PUCCH transmission), UE115-amay be configured to transmit the PUCCH transmission in accordance with intra-PUCCH resource beam hopping (e.g., with or without repetition), intra-slot repetition, or inter-slot repetition. Intra-PUCCH resource beam hopping, as described with reference toFIGS. 4A and 4B, may refer to a UE115transmitting UCI via two different beams in the same PUCCH resource, where the UE115may transmit UCI via a first beam215-ain a first portion of the PUCCH resource and transmit UCI via a second beam215-bin a second portion of the PUCCH resource. Intra-slot repetition, as described with reference toFIG. 3B, may refer to a UE115transmitting UCI via two different beams215in a PUCCH resource in two different sub-slots of a slot, where the UE115may transmit UCI via a first beam215-ain a PUCCH resource of a first sub-slot and transmit UCI via a second beam215-bin the PUCCH resource of a second sub-slot. The PUCCH resource used in the first sub-slot and the second sub-slot may be the same PUCCH resource. As the UE115is configured to transmit the same UCI in a PUCCH resource in two different sub-slots, the UCI transmitted in the second sub-slot may be repeated UCI of the UCI transmitted in the first sub-slot. Inter-slot repetition, as described with reference toFIG. 3A, may refer to a UE115transmitting UCI via two different beams215in a PUCCH resource in two different slots, where the UE115may transmit UCI via a first beam215-ain a PUCCH resource of a first slot and transmit UCI via a second beam215-bin the PUCCH resource of a second slot. The PUCCH resource used in the first slot and the second slot may be the same PUCCH resource. As the UE115is configured to transmit the same UCI in a PUCCH resource in two different slots, the UCI transmitted in the second slot may be repeated UCI of the UCI transmitted in the first slot.

In some cases, UE115-amay determine which one of intra-PUCCH resource beam hopping (e.g., without repetition), intra-slot repetition, or inter-slot repetition to use based on a number of repetitions associated with the PUCCH format of the PUCCH resource. For example, UE115-amay be configured to transmit the UCI in a PUCCH format, such as PUCCH format 1, that has been configured with two slots (e.g., nrofSlots=2). In such cases, UE115-amay be configured to transmit the UCI via the multiple beams215in accordance with inter-slot repetition based on inter-slot repetition allowing a UE115to transmit UCI in one slot and repeated UCI in a second slot (e.g., two slots). In another example, UE115-amay be configured to transmit the UCI in a PUCCH format that has been configured with two sub-slots of a slot. In such cases, UE115-amay be configured to transmit the UCI via the multiple beams215in accordance with intra-slot repetition based on intra-slot repetition allowing a UE115to transmit UCI in one sub-slot and repeated UCI in a second sub-slot (e.g., two sub-slots). In another example, UE115-amay be configured to transmit the UCI in a PUCCH format that has been configured with one slot (or sub-slot), or has not been assigned a number of slots (or sub-slots), as such UE115-amay not transmit the UCI with repetitions and thus may be configured to transmit the UCI via the multiple beams215in accordance with intra-PUCCH resource beam hopping because the UE115may transmit the UCI via a first portion of a PUCCH resource and via a second portion of the same PUCCH resource, such that the UCI transmission may be performed without repetition of the PUCCH resource.

In some implementations, intra-PUCCH resource beam hopping with repetitions, as described with reference toFIG. 4B, in which the UE115may perform intra-PUCCH resource beam hopping in multiple slots (e.g., or sub-slots) may be a beneficial transmission configuration. For example, UE115-amay transmit UCI via a first beam215-ain a first portion of a PUCCH resource and transmit UCI via a second beam215-bin a second portion of a PUCCH resource in a first slot and UE115-amay transmit according to the same configuration in a second slot, or third slot. As such, if UE115-ais configured with UCI to transmit in a PUCCH resource that is associated with a number of repetitions greater than one (e.g., a number of slots or sub-slots greater than one) and UE115-areceives an indication that multiple beams215(e.g., a first beam215-aand a second beam215-b) are activated for the PUCCH resource, UE115-amay be configured with a method for determining to use intra-PUCCH resource beam hopping with repetitions, intra-slot repetition, or inter-slot repetition for the multi-beam UCI transmission with repetition.

In some implementations, UE115-amay receive an indication of a transmission configuration to use to distinguish between intra-PUCCH resource beam hopping with repetition, intra-slot repetition, and inter-slot repetition in which each configuration is associated with a number of PUCCH repetitions greater than one. In some cases, UE115-amay receive an indication that indicates that UE115-ashould use intra-PUCCH resource beam hopping with repetition for the multi-beam UCI transmission. The indication may be included in RRC signaling or MAC-CE signaling. For example, if UE115-areceives an indication to transmit UCI in a PUCCH resource configured with a number of repetitions greater than one, and receives an indication that multiple beams are activated (e.g., more than one spatial relation information is activated) for the PUCCH resource, such as in a MAC-CE message, then UE115-amay receive an additional indication that UE115-ais to transmit the UCI via the multiple beams215in accordance with a certain transmission configuration. The additional indication may be included in the MAC-CE message. In some cases, the additional indication may indicate that UE115-ais to transmit the UCI via the multiple beams215in accordance with intra-PUCCH resource beam hopping with repetition. In some cases, the additional indication may indicate that UE115-ais to transmit the UCI via the multiple beams215in accordance with inter-slot repetition. In some cases, the additional indication may indicate that UE115-ais to transmit the UCI via the multiple beams215in accordance with intra-slot repetition. In some cases, the additional indication may indicate that UE115-ais to transmit the UCI via the multiple beams215not in accordance with intra-PUCCH resource beam hopping with repetition. In such a case, UE115-amay default to inter-slot repetition or intra-slot repetition based on whether UE115-ais configured to repeat the UCI in slots or sub-slots.

In some implementations, UE115-amay receive an indication that enables intra-PUCCH resource beam hopping with repetition, where UE115-amay receive the indication dynamically, semi-statically, or aperiodically. For example, UE115-amay receive an RRC message that indicates that intra-PUCCH resource beam hopping with repetition is enabled, where the indication may be included in the RRC message as an RRC parameter. When intra-PUCCH resource beam hopping with repetition is enabled, UE115-amay default to intra-PUCCH resource beam hopping with repetition to transmit the UCI via the multiple beams215in accordance with the number of repetitions and the repetition configuration (e.g., PUCCH repetition in different slots, or different sub-slots) associated with the PUCCH resource, or PUCCH format of the PUCCH resource. If intra-PUCCH resource beam hopping with repetition is not enabled (e.g., disabled), UE115-amay default to inter-slot repetition or intra-slot repetition based on whether UE115-ais configured to repeat the UCI in slots or sub-slots. In some cases, the RRC parameter may be configured per PUCCH resource or per PUCCH format. For example, intra-PUCCH resource beam hopping with repetition may be enabled or disabled per PUCCH resource (e.g., per certain time and frequency resources within a slot). In another example, intra-PUCCH resource beam hopping with repetition may be enabled or disabled per PUCCH format, and as such, the UE115may determine the intra-PUCCH resource beam hopping with repetition enablement or disablement of an PUCCH resource based on the PUCCH format associated with the PUCCH resource.

In some implementations, UE115-amay be configured dynamically, semi-persistently, or aperiodically to determine which transmission configuration to use based on the type of UCI the UE115is configured to transmit and/or based on the payload of the UCI the UE115is configured to transmit. For example, UE115-amay be configured to determine to use intra-PUCCH resource beam hopping with repetition based on a type of UCI UE115-ais configured to transmit. UE115-amay receive or otherwise be configured with a mapping (e.g., a lookup table) of UCI types that are associated with intra-PUCCH resource beam hopping, UCI types that are associated with intra-slot repetition, and/or UCI types that are associated with inter-slot repetition. In some cases, the mapping may include only the UCI types mapped to the intra-PUCCH resource beam hopping. The mappings may be updated dynamically, aperiodically, or semi-persistently, such as via RRC signaling, MAC-CE signaling, or downlink control information (DCI) signaling. As such, UE115-amay determine the type of UCI UE115-ais configured to transmit, determine the transmission configuration associated with the UCI type, and transmit the multi-beam UCI transmission in accordance with the determined transmission configuration. In the cases that the mapping does not include the determined UCI type, UE115-amay determine that UE115-ais to transmit the UCI transmission in accordance with inter-slot or intra-slot repetition based on whether UE115-ais configured to repeat the UCI in slots or sub-slots.

In another example, UE115-amay be configured to determine to use intra-PUCCH resource beam hopping with repetition based on a payload of the UCI UE115-ais configured to transmit. UE115-amay be configured dynamically, semi-persistently, or aperiodically with one or more UCI payload thresholds. For example, UE115-amay be configured with one UCI payload threshold. If the payload of the UCI UE115-ais configured to transmit is greater than the UCI payload threshold, UE115-amay determine to transmit the multi-beam UCI transmission in accordance with an intra-PUCCH resource. If the payload of the UCI UE115-ais configured to transmit is less than the UCI payload threshold, UE115-amay determine to transmit the multi-beam UCI transmission in accordance with inter-slot or intra-slot repetition based on whether UE115-ais configured to repeat the UCI in slots or sub-slots. The one or more UCI payload thresholds may be updated dynamically, aperiodically, or semi-persistently, such as via RRC signaling, MAC-CE signaling, or DCI signaling.

In some implementations, a UE115may not be configured to perform intra-PUCCH resource beam hopping with repetition. In some cases, intra-PUCCH resource beam hopping with repetition may be disabled, as described herein, or a UE115-amay not be configured with the ability to transmit in accordance with intra-PUCCH resource beam hopping with repetition. In either case, UE115-amay determine which transmission configuration to use based on a number of repetitions. If UE115-ais configured to transmit UCI via multiple beams with no repetitions (e.g., repetitions equal to one, slots equal to one, sub-slots equal to one), then UE115-amay determine to use intra-PUCCH resource beam hopping without repetitions. If UE115-ais configured to transmit UCI via multiple beams with a number of repetitions greater than one (e.g., a number of slots greater than one, a number of sub-slots greater than one), then UE115-amay determine to use intra-slot repetition or inter-slot repetition based on whether UE115-ais configured to repeat the UCI in slots or sub-slots and in accordance with the number of repetitions.

Additionally or alternatively, UE115-amay be configured to determine to use intra-PUCCH resource beam hopping without repetitions based on receiving an RRC parameter that enables intra-PUCCH resource beam hopping without repetitions (e.g., enableBeamHopping), where intra-PUCCH resource beam hopping without repetitions may be enabled per PUCCH resource or per PUCCH format. In some cases, if UE115-areceives the RRC indication that intra-PUCCH resource beam hopping without repetitions is enabled for a PUCCH resource or PUCCH format that is associated with a number of repetitions greater than one, then UE115-amay determine that an error has occurred because UE115-amay not be configured to perform intra-PUCCH resource beam hopping with repetitions.

In either case that UE115-ais able or unable to perform intra-PUCCH resource beam hopping with repetitions, UE115-amay be configured to determine one or more error cases. For example, if a UE115is configured to transmit UCI in a PUCCH resource in which more than one beam is activated (e.g., by MAC-CE), but the UE115is not configured with a number of repetitions greater than one, and the UE115is not configured with intra-PUCCH resource beam hopping without repetition, then the UE115may determine that an error has occurred because the UE115is not enabled to use a transmission configuration without repetition, but the UE115also has no repetitions to transmit. In some cases, if UE115-adetects an error, then UE115-amay be configured to fall back to a default transmission configuration. For example, UE115-amay be configured to transmit UCI in the configured PUCCH resource without repetition and using one of the multiple activated beams (e.g., the first indicated beam, the first activated beam, the beam directed at the serving base station105) as a default transmission configuration. In some cases, if UE115-adetects an error, or otherwise, UE115-amay be configured to default to inter-slot repetition with a default number of repetitions, such as two slot repetitions. In some cases, if UE115-adetects an error, or otherwise, UE115-amay be configured to default to intra-slot repetition with a default number of repetitions, such as two sub-slot repetitions. In some cases, if UE115-adetects an error, or otherwise, UE115-amay be configured to default to intra-PUCCH resource beam hopping without repetitions. In some cases, if UE115-adetects an error, or otherwise, UE115-amay be configured to default to intra-PUCCH resource beam hopping with repetitions, in accordance with a default number of repetitions, such as two slot or sub-slot repetitions.

FIGS. 3A and 3Billustrate examples of transmission configurations300and301that support techniques for performing uplink control channel beam hopping and repetition in accordance with aspects of the present disclosure. The transmission configurations300and301may be implemented by a base station and a UE, which may be examples of a base station and a UE as described with reference toFIGS. 1 and 2. In some cases, a UE may be configured to perform a UCI transmission procedure in which the UE may transmit UCI via one or more beams to one or more base stations. The UE may transmit the UCI in accordance with transmission configuration300or transmission configuration301. Additionally or alternatively, other wireless devices, such as a base station may indicate a UCI transmission configuration and or receive the UCI transmission from the UE.

As described herein, a UE may be configured to transmit UCI in a PUCCH resource in accordance with a number of slots or sub-slots greater than one (e.g., with repetition), where multiple beams have been activated for the PUCCH resource. As such, the UE is configured to transmit the UCI via the first beam315-aand the second beam315-bin the PUCCH resource in more than one slot, or sub-slot. The UE may be configured to do so in accordance with one or more transmission configurations such as inter-slot repetition, intra-slot repetition, or intra-PUCCH resource beam hopping with repetitions. The UE may be configured to transmit the UCI in accordance with intra-PUCCH resource beam hopping without repetitions if no repetitions are associated the PUCCH resource or PUCCH format.

FIG. 3Adepicts a transmission configuration in which a UE transmits UCI via a first beam315-aand second beam315-bin accordance with inter-slot repetition. In inter-slot repetition, one PUCCH resource310in a first slot305-amay carry UCI, and the same PUCCH resource310in another one or more slots305may carry a repetition of the UCI. For example, a UE may be configured to transmit UCI (e.g., a UCI message) in a PUCCH resource310in which two beams have been activated, a first beam315-aand a second beam315-b. The UE may also determine that the PUCCH resource310and/or the PUCCH format of the PUCCH resource310is associated with two slots (e.g., a number of repetitions equal to two). As such, the UE may transmit the UCI in PUCCH resource310-ain slot305-bvia the first beam315-aand transmit repeated UCI in the repeated PUCCH resource310-bin slot305-bvia the second beam315-b. The UCI transmitted in slot305-aand slot305-bmay be the same, and the time and frequency resources of PUCCH resource310-aand310-bin the respective slots305may be the same. In some cases, the UE may be activated to perform inter-slot repetition based on a number of repetitions for a PUCCH resource310or PUCCH format being greater than one (e.g., a number of slots being greater than one) and based on receiving an indication that the PUCCH resource310carrying the UCI is activated with more than one beam315. The number of repetitions may be configured in an RRC message or MAC-CE message, and the number of activated beams315for a PUCCH resource310may be indicated in a MAC-CE message. In some cases, the UE may be activated to perform inter-slot repetition based on an implicit or explicit indication to do so, or based on inter-slot repetition being a default configuration, as described with reference toFIG. 2.

FIG. 3Bdepicts a transmission configuration in which a UE transmits UCI via a first beam315-aand second beam315-bin accordance with intra-slot repetition. In intra-slot repetition, one PUCCH resource310in a first sub-slot320-amay carry UCI, and the same PUCCH resource310in another one or more sub-slots320of a slot305(e.g., slot305-c) may carry a repetition of the UCI. For example, a UE may be configured to transmit UCI (e.g., an UCI message) in a PUCCH resource310in which two beams have been activated, a first beam315-aand a second beam315-b. The UE may also determine that the PUCCH resource310and/or the PUCCH format of the PUCCH resource310is associated with two sub-slots (e.g., a number of repetitions equal to two). As such, the UE may transmit the UCI in PUCCH resource310-cin sub-slot320-avia the first beam315-aand transmit repeated UCI in the repeated PUCCH resource310-din sub-slot320-bvia the second beam315-b. The UCI transmitted in sub-slot320-aand sub-slot320-bmay be the same, and the time and frequency resources of PUCCH resource310-cand310-din the respective sub-slots320may be the same. In some cases, the UE may be activated to perform intra-slot repetition based on a number of repetitions for a PUCCH resource310or PUCCH format being greater than one (e.g., a number of sub-slots being greater than one) and based on receiving an indication that the PUCCH resource carrying the UCI is activated with more than one beam315. The number of repetitions may be configured in an RRC message or MAC-CE message, and the number of activated beams315for a PUCCH resource310may be indicated in a MAC-CE message. In some cases, the UE may be activated to perform intra-slot repetition based on an implicit or explicit indication to do so, or based on intra-slot repetition being a default configuration, as described with reference toFIG. 2.

FIGS. 4A and 4Billustrate examples of transmission configurations400that support techniques for performing uplink control channel beam hopping and repetition in accordance with aspects of the present disclosure. The transmission configurations400and401may be implemented by a base station and a UE, which may be examples of a base station and a UE as described with reference toFIGS. 1 through 3B. In some cases, a UE may be configured to perform a UCI transmission procedure in which the UE may transmit UCI via one or more beams to one or more base stations. The UE may transmit the UCI in accordance with transmission configuration400or transmission configuration401. Additionally or alternatively, other wireless devices, such as a base station may indicate a UCI transmission configuration and or receive the UCI transmission from the UE.

As described herein, a UE may be configured to transmit UCI in a PUCCH resource in accordance with a number of slots or sub-slots greater than one (e.g., with repetition), or with a number of slots or sub-slots equal to one (e.g., without repetition). In some cases, multiple beams have been activated for the PUCCH resource. As such, the UE is configured to transmit the UCI via the first beam415-aand the second beam415-bin the PUCCH resource in one slot, one sub-slot, more than one slot, or more than one sub-slot based on the number of repetitions. The UE may be configured to do so in accordance with one or more transmission configurations such as inter-slot repetition, intra-slot repetition, intra-PUCCH resource beam hopping with repetitions, or intra-PUCCH resource beam hopping without repetitions. The UE may be configured to transmit the UCI in accordance with intra-PUCCH resource beam hopping without repetitions, if no repetitions are associated the PUCCH resource or PUCCH format.

FIG. 4Adepicts a transmission configuration in which a UE transmits UCI (e.g., a UCI message) via a first beam415-aand second beam415-bin accordance with intra-PUCCH resource beam hopping without repetitions. In intra-PUCCH resource beam hopping, UCI is transmitted in one PUCCH resource410-ain a slot405-ain which the PUCCH resource410-ais divided into a first portion and second portion, the first portion and the second portion may include the same amount of time and frequency resources. In some cases, the first portion may include a first set of symbols of the PUCCH resource410-aand the second portion may include a second set of symbols of the PUCCH resource410-a, where the first set and the second set of symbols include the same or a similar number of symbols. The UE may be configured to transmit the UCI via the first beam415-ain the first portion of the PUCCH resource410-aand transmit UCI via the second beam415-bin the second portion of the PUCCH resource410-a. As the UE is transmitting the UCI via the first beam415-aand the second beam415-bin the same PUCCH resource410-a, the UE may not be performing repetition. In some cases, the UE may be activated to perform intra-PUCCH resource beam hopping without repetition based on a number of repetitions for a PUCCH resource410or a PUCCH format being equal to one (e.g., a number of slots or sub-slots being equal one) and based on receiving an indication that the PUCCH resource410carrying the UCI is activated with more than one beam415. The number of activated beams415for a PUCCH resource410may be indicated in a MAC-CE message. In some cases, the UE may be activated to perform intra-PUCCH resource beam hopping without repetition based on an implicit or explicit indication to do so, or based on intra-PUCCH resource beam hopping without repetition being a default configuration, as described with reference toFIG. 2.

FIG. 4Bdepicts a transmission configuration in which a UE transmits UCI (e.g., a UCI message) via a first beam415-aand second beam415-bin accordance with intra-PUCCH resource beam hopping with repetitions. Intra-PUCCH resource beam hopping may be a combination of intra-PUCCH resource beam hopping as described with reference toFIG. 4A, but repeated in multiple slots, or sub-slots. For example, a PUCCH resource410-bin slot405-bis divided into a first portion and second portion, the first portion and the second portion may include the same amount of time and frequency resources. In some cases, the first portion may include a first set of symbols of the PUCCH resource410-band the second portion may include a second set of symbols of the PUCCH resource410-b, where the first set and the second set of symbols include the same or a similar number of symbols. The UE may be configured to transmit the UCI via the first beam415-ain the first portion of the PUCCH resource410-band transmit UCI via the second beam415-bin the second portion of the PUCCH resource410-b. The UE may continue this configuration up to the configured number of configurations. For example, if the UE is configured with two slots, the UE may perform the same or similar configuration in a second slot. For example, a PUCCH resource410-cin slot405-cis divided into a first portion and second portion, where PUCCH resources410-band410-cmay include the same time and frequency resources within a slot405. The first portions of PUCCH resources410-band410-cmay include the same or similar time and frequency resources and the second portions of PUCCH resources410-band410-cmay include the same or similar time and frequency resources. As was performed in slot405-a, a UE may be configured to transmit the UCI via the first beam415-ain the first portion of the PUCCH resource410-cand transmit UCI via the second beam415-bin the second portion of the PUCCH resource410-c. As such, the UE may repeat the procedure performed in slot405-bin slot405-c.

In some cases, the UE may be activated to perform intra-PUCCH resource beam hopping with repetition based on a number of repetitions for a PUCCH resource410or a PUCCH format being greater than one (e.g., a number of slots or sub-slots being greater than one) and based on receiving an indication that the PUCCH resource410carrying the UCI is activated with more than one beam415. The number of repetitions may be configured in an RRC message or MAC-CE message, and the number of activated beams415for a PUCCH resource410may be indicated in a MAC-CE message. In some cases, the UE may be activated to perform intra-PUCCH resource beam hopping with repetition based on an implicit or explicit indication to do so, or based on intra-PUCCH resource beam hopping with repetition being a default configuration, as described with reference toFIG. 2.

FIG. 5illustrates an example of a process flow500that supports techniques for performing uplink control channel beam hopping and repetition in accordance with aspects of the present disclosure. The process flow500may illustrate an example transmission configuration determination procedure. For example, UE115-bmay perform a transmission configuration determination procedure for transmitting an uplink transmission to one or more base stations105. Base station105-cand UE115-bmay be examples of the corresponding wireless devices described with reference toFIGS. 1 through 4B. In some cases, instead of UE115-bimplementing the configuration determination procedure, a different type of wireless device (e.g., a base station105) may perform the procedure. 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.

At505, UE115-bmay receive, from base station105-c, a message scheduling transmission, by UE115-b, of UCI in an uplink control channel resource (e.g., PUCCH resource).

At510, UE115-bmay receive an indication that UE115-bis scheduled to transmit the UCI via a first beam during the uplink control channel resource and via a second beam during the uplink control channel resource.

At515, UE115-bmay determine a number of repetitions associated with transmitting the UCI.

At520, UE115-bmay transmit the UCI via one of inter-slot repetition, intra-PUCCH resource beam hopping, or intra-slot repetition based on the number of repetitions.

In some cases, UE115-bmay receive a second message indicating the number of repetitions associated with transmitting the UCI, where the number of repetitions is greater than one. In some implementations, UE115-bmay receive a second message indicating that UE115-bis scheduled to transmit the UCI via the first beam and the second beam according to intra-PUCCH resource beam hopping. The second message may be included in a MAC-CE, where transmitting the UCI via intra-PUCCH resource beam hopping is based on the second message and the number of repetitions being greater than one.

If UE115-breceives a second message indicating the number of repetitions associated with transmitting the UCI, where the number of repetitions is greater than one, UE115-bmay determine to transmit the UCI via inter-slot repetition based on the number of repetitions being greater than one, transmit the UCI via the first beam during the uplink control channel resource in a first slot, and transmit the UCI via the second beam during the uplink control channel resource in a second slot, where the second slot is different than the first slot.
