Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration message that includes a sounding reference signal (SRS) configuration that indicates a first set of SRS transmission parameters for the UE. The UE may receive an indication to modify the SRS configuration, wherein the indication is associated with a second set of SRS transmission parameters that is different from the first set of SRS transmission parameters. The UE may transmit one or more SRSs according to the second set of SRS transmission parameters and based at least in part on receiving the indication. Numerous other aspects are provided.

Abstract: Apparatus, methods, and computer-readable media for facilitating per bandwidth part TCI state or spatial relation are disclosed herein. For example, aspects disclosed herein provide techniques for enabling a UE (e.g., a reduced capability UE) to associate at least one of a TCI state or a spatial relation with respective hopping regions. An example method for wireless communication at a UE includes determining, while communicating using a first frequency range comprising a first set of frequency hops, at least one of a TCI state or a spatial relation for communicating using a second frequency range comprising a second set of frequency hops. The example method also includes communicating, after switching communication from the first frequency range to the second frequency range, using the second frequency range based on the determined at least one of the TCI state or the spatial relation.

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 search space configuration that identifies one or more parameters associated with demodulation reference signals (DMRSs) for a physical downlink control channel (PDCCH) communication. The UE may decode a PDCCH candidate associated with the PDCCH communication, based at least in part on the one or more parameters associated with the DMRSs, wherein the PDCCH candidate is aggregated over one or more PDCCH monitoring occasions. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may broadcast a first set of network coding encoded packets for reception by a plurality of receivers, and receive feedback information associated with the first set of network coding encoded packets, the feedback information indicating that one or more receivers of the plurality of receivers did not successfully receive a quantity of network coding encoded packets that satisfies a decoding threshold associated with recovering the plurality of source packets, and a first subset of network coding encoded packets of the first set of network coding encoded packets that were not successfully received by at least one receiver. The transmitter may broadcast a second set of network coding encoded packets. The second set of network coding encoded packets may include at least the first subset of network coding encoded packets. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for blind decoding and channel estimation (BD/CE) limitations and configuration of new radio (NR) physical downlink control channel (PDCCH) repetition. A method that may be performed by a user equipment (UE) includes receiving, from a base station, an indication of at least one blind detection limit for detecting a control channel from a set of blind detection limits and monitoring for the control channel based on the received indication of the at least one blind detection limit for detecting the control channel.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mobility techniques that allow for dynamically updating a set of cells activated to serve a user equipment (UE) and synchronizing with the cells activated to serve the UE. An example method generally includes receiving, from a network entity, signaling indicating a set of cells supported by one or more distributed units (DUs) under a common central unit (CU) and one or more timing advance groups (TAGs) for the set of cells; identifying a subset of the set of cells activated to serve the UE; receiving physical (PHY) layer or medium access control (MAC) layer mobility signaling; updating the subset of activated cells based on the mobility signaling; and communicating with the subset of activated cells based on a timing advance associated with the one or more TAGs in which the updated subset of activated cells belong.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may perform a first encoding operation on source packets that generates a first set of network coding encoded packets and may broadcast the first set of network coding encoded packets for reception by a plurality of receivers. The transmitter may receive feedback information associated with the first set of network coding encoded packets, the feedback information indicating that a first subset of network coding encoded packets were received by at least one of the plurality of receivers, the feedback information further indicating that one or more receivers of the plurality of receivers did not successfully recover all of the plurality of source packets. The transmitter may broadcast a second set of network coding encoded packets that does not include any of the first subset of network coding encoded packets. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and apparatuses for supporting network transmissions using unicast sidelink communications. A base station (BS) may transmit a set of encoded packets to a number of user equipment (UEs) and receive feedback messages from the UEs that indicate sets of decoded packets. Based on the feedback messages, the BS may transmit an updated set of encoded packets based on a difference between the set of encoded packets and the union of decoded packets. The BS may transmit an instruction to a first UE to transmit a unicast sidelink communication to a second UE that includes a set of missed packets that includes one or more decoded packets that were decoded by the first UE but were not decoded by the second UE. The first UE may transmit the unicast sidelink communication to the second UE.

Abstract: Techniques and apparatus for avoiding hybrid automatic repeat request (HARQ) process identifier (ID) conflicts in scenarios where multiple semi persistently scheduled (SPS) configurations share the same pool of HARQ process IDs are provided. One technique involves receiving an indication of SPS configurations, where each SPS configuration allocates a set of SPS occasions for physical downlink shared channel (PDSCH) transmissions. A conflict is detected between a first HARQ process ID associated with a first SPS occasion of a first SPS configuration and a second HARQ process ID associated with a second SPS occasion of a second SPS configuration, where the first SPS occasion occurs prior to the second SPS occasion. At least one action to resolve the conflict is taken based on predetermined rule(s), in response to detecting the conflict.

Abstract: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by base station. The method generally includes transmitting, to a user-equipment (UE), a packet indicating a beam switch associated with communication with the UE, receiving an acknowledgment (ACK) message, detecting that the ACK message is configured to indicate whether parsing of contents of the packet was successful, determining a timing of the beam switch based on the detection, and performing the beam switch in accordance with the determination of the timing.
