Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a UE capability associated with reference signal reporting by the UE. The UE may receive, from the base station, a data packet and an indication of a mode for hybrid automatic repeat request (HARQ) feedback reporting based on the UE capability. The UE may determine that a slot includes first resources for transmitting a sounding reference signal (SRS) and second resources for transmitting HARQ feedback for the data packet. The UE may transmit, to the base station during the slot and based on the indication of the mode for HARQ feedback reporting, the HARQ feedback and one or more of the SRS or CSI associated with the HARQ feedback.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus for wireless communication at a wireless node comprises one or more memories, and one or more processors, coupled to the memory. The one or more processors can be configured to transmit or receive tri-state feedback indicating a result of decoding one or more communications. The tri-state feedback can be associated with three potential states. The three potential states can indicate whether (i) decoding of a control channel was unsuccessful, (ii) decoding of the control channel was successful and decoding of a data channel was unsuccessful, or (iii) decoding of the control channel and the data channel was successful.

Abstract: Wireless communications systems and methods related to resource partitioning for sidelink are provided. A first user equipment (UE) transmits, to a second UE, a time-division duplexing (TDD) configuration indicating a first set of resources time-multiplexed with a second set of resources in a sidelink resource pool, wherein the first set of resources is associated with a first link, and wherein the second set of resources is associated with a second link different from the first link. The first UE receives from the second UE over the first link, a first communication signal in a resource of the first set of resources. The first UE transmits, to the second UE over the second link, a second communication signal using a resource of the second set of resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a first subset size parameter associated with a first priority, and an indication of a second subset size parameter associated with a second priority. The UE may determine a first set of HARQ-ACK/NACK feedback associated with downlink communications having the first priority and a second set of HARQ-ACK/NACK feedback associated with downlink communications having the second priority. The UE may select a first subset of HARQ-ACK/NACK feedback from the first set of HARQ-ACK/NACK feedback based on the first subset size parameter, and a second subset of HARQ-ACK/NACK feedback from the second set of HARQ-ACK/NACK feedback based on the second subset size parameter. The UE may transmit, during the uplink slot, the first subset and/or the second subset of HARQ-ACK/NACK feedback. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, from at least an acknowledgment (ACK)-only feedback configuration and a negative ACK (NACK)-only feedback configuration and based at least in part on an error rate and a traffic condition associated with a semi-persistent scheduling (SPS) resource allocation, a feedback configuration for the SPS resource allocation. The UE may transmit feedback regarding the SPS resource allocation using the selected feedback configuration. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station may configure a user equipment (UE) with a low latency mode indication that indicates one or more different retransmission timelines or repetition techniques relative to communications that are not associated with the low latency mode indication. The base station may provide the low latency mode indication in downlink control information (DCI) that may include a resource grant for uplink resources for an uplink communication, such as for a UE transmission of pose information of an extended reality (XR) application. The low latency mode indication may signal that no retransmissions of the uplink communication are to be transmitted, that a different retransmission timeline is enabled for low latency mode communications, that retransmissions may happen based on a particular timeline that is determined according to one or more timers, or any combinations thereof.

Abstract: Aspects of the present disclosure provide techniques for wireless communication. A method by a user equipment (UE) includes receiving scheduling information from a network entity. The scheduling information schedules transmission of a first uplink (UL) channel repetition of a plurality of UL channel repetitions in a first full duplex (FD) slot of a plurality of slots. Additionally, the first UL channel repetition is associated with one or more time domain resource allocations (TDRAs) and one or more frequency domain resource allocations (FDRAs). Additionally, based on the one or more FDRAs associated with the first UL channel repetition, a portion of the first UL channel repetition is scheduled to occur in a downlink subband of the first FD slot. The method also includes taking one or more actions to transmit the first UL channel repetition based on the scheduling information.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for channel state information (CSI) report structure for dynamic antenna port adaptation. In some aspects, a user equipment (UE) and a network entity may support a CSI report configuration according to which the UE may include a respective set of CSI parameters for each of multiple codebooks. For example, the UE may compute a respective set of CSI parameters for each of multiple codebooks in accordance with a CSI report configuration and may transmit a CSI report including the respective sets of CSI parameters for each of the multiple codebooks. The network entity may use the respective sets of CSI parameters for each of the multiple codebooks to inform a dynamic antenna panel configuration update at the network entity.
