Abstract: A configuration to suspend UE communication with a base station based on instructions from the base station. The apparatus receives, from a base station, a silencing instruction for at least one of uplink communication or downlink communication. The apparatus determines a first duration associated with the at least one of uplink communication or downlink communication based on the silencing instruction. The apparatus refrains from all of the at least one of uplink communication or downlink communication with the base station for the first duration in response to receiving the silencing instruction.

Abstract: Certain aspects of the present disclosure provide techniques for measurements on a first frequency band applicable to procedures on a second frequency band. A technique that may be performed by a user equipment (UE) may include sending a base station (BS) an indication of the first frequency band, which may be a preferred measurement frequency band. The UE may then measure one or more reference signals (RSs) on the preferred measurement frequency band. The UE may then apply the measurements of the one or more RSs on the preferred measurement frequency band for one or more procedures on the second frequency band.

Abstract: Aspects of the disclosure relate to wireless communication networks having a capability of controlling the mapping of reference signals onto a carrier based on one or more Doppler parameters. A demodulation reference signal (DMRS) is mapped to a carrier according to a pattern based on one or more Doppler parameters, such as a Doppler frequency and/or a rate of change of channel conditions. In a further example, if an initial transmission of an information packet fails due to a high Doppler scenario, the probability of success of the retransmission may be improved by altering the DMRS configuration to account for the high Doppler scenario. Other aspects, examples, and features are also claimed and described.

Abstract: A user equipment (UE) transmits, to a base station, a transmission configuration indication (TCI) report indicating associations between a plurality of TCIs and one or more UE panels of the UE; receives, from the base station in response to the TCI report, a TCI configuration message indicating a first set of TCI of the plurality of TCIs for a physical downlink control channel (PDCCH) transmission; and skips monitoring, based at least in part on the TCI configuration message, a control resource set (CORESET) associated with a second set of TCI of the plurality of TCIs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first transmit receive point (TRP) may transmit a first physical downlink shared channel (PDSCH) communication to a user equipment (UE), wherein the first PDSCH communication includes a first set of layers for a codeword, and wherein a second set of layers for the codeword are transmitted to the UE in a second PDSCH communication from a second TRP. The first TRP may receive from the UE, acknowledgement or negative acknowledgement (ACK/NACK) information corresponding to the codeword. The first TRP may adjust a contention window size based at least in part on a determination that a condition, associated with the ACK/NACK information, is satisfied. Numerous other aspects are provided.

Abstract: A UE receives a first indication of a Wake-Up Signal (WUS) resource for another UE. The UE identifies a conflict between a resource allocated to the UE and the WUS resource for the other UE based on the first indication. The UE modifies communication with a base station in the resource in response to the identifying of the conflict. A base station identifies a conflict between a resource for communication with a first UE and a WUS for another UE and modifies the communication with the first UE in the resource in response to identifying the conflict.
