Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a configuration of a retransmission of a first message of a random access procedure based on a set of transmission configuration options transmitted by a base station. For example, the UE may transmit the first message but may reconfigure the first message for the retransmission based on the transmission configuration options. Additionally, the UE may configure a set of transmission configuration states based on the transmission configuration options for transmitting/retransmitting the first message. In some cases, the UE may determine to switch transmission configuration states based on a trigger signaled by the base station and/or a determination by the UE. Additionally, the UE may transmit an indication of a log of state transitions performed prior to a retransmission of the first message to facilitate combining of the retransmissions at the base station.

Abstract: Certain aspects of the present disclosure provide techniques for channel state information (CSI) reporting with time domain (TD) compression. A method that may be performed by a user equipment (UE) includes receiving one or more CSI-RS from a base station (BS). The UE measures the one or more CSI-RS. The UE determining a mapping order for placing CSI feedback in one or more CSI reports and sends the one or more CSI reports to the BS based on the measurements, the one or more CSI reports providing TD compressed CSI feedback including at least linear combination coefficients associated with TD bases used for the TD compression.

Abstract: This disclosure provides systems, methods and apparatus including computer programs encoded on computer storage media, for a user equipment (UE) to determine and apply limits to physical downlink control channel (PDCCH) processing in a dual active protocol stack handover scenario. In one aspect, the UE utilizes a joint blind decode capability for both a source cell group and a target cell group to determine whether a total limit for PDCCH candidates to monitor or non-overlapped control channel elements (CCEs) to monitor is applicable. The UE may identify a per cell limit for each configured single transmit receive point (TRP) cell and each multiple TRP cell based on a sub-carrier spacing SCS of the cell and the determination. The UE may include an interface configured to obtain a PDCCH for a slot. The UE may perform blind decoding operations on CCEs up to the per cell monitoring limit for each cell.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for sidelink (SL) power saving using SL wake up signals (WUSs). A method that may be performed by a user equipment (UE) includes determining resources for SL WUS transmissions from a second UE, based on a WUS resource configuration, monitoring the resources for an SL WUS from the second UE, and participating in SL communications with the second UE if an SL WUS is detected during the monitoring..

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a request to apply demodulation reference signal (DMRS) bundling to uplink transmissions. The UE may transmit multiple uplink transmissions. The UE may transmit an indication of whether the UE is able to comply with the request based at least in part on whether the UE is able to maintain phase coherence across the multiple uplink transmissions. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify a sounding reference signal (SRS) resource associated with an uplink precoding resource block group of a physical uplink shared channel (PUSCH) resource. The user equipment may precode a portion of a PUSCH communication, to be transmitted in the uplink precoding resource block group, based at least in part on the identified SRS resource. The user equipment may transmit the PUSCH communication after precoding the PUSCH communication. Numerous other aspects are provided.
