Abstract: Wireless communications systems and methods related to UE cooperation are provided. A base station (BS) may assist a UE in cooperating with other UEs. A UE may transmit a cooperative UE update request to aBS, indicating a number of candidate cooperative UE sets. The UE may also transmit information to the BS about the candidate cooperative UE sets such as UE capability information, location information, and channel measurements. Additional measurements maybe requested by the BS. The BS may use the information from the UEs together with BS-side information such as configuration information and TRP information in order to determine which of the candidate cooperative UE sets is preferred. The BS may then configure and communicate with selected cooperative UE set.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a control message (e.g., downlink control information (DCI), radio resource control) indicating a configuration for a signal, where the configuration may indicates whether the signal is associated with one or more unified transmission configuration indicator (TCI) states of a selected unified TCI codepoint. The UE may receive a first DCI message indicating a set of one or more activated TCI codepoints that are each associated with one or more TCI states, and receive a second DCI message indicating the selected unified TCI codepoint from the set of one or more activated TCI codepoints. The UE may apply a TCI state for communication of the signal in accordance with the configuration.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. The UE may be configured to support uplink power control for multiple random access channel (RACH) procedures. A medium access control layer entity at the UE may maintain multiple sets of counters and parameters for multiple simultaneous RACH procedures. In some cases, the UE may perform simultaneous RACH procedures with network entities associated with different timing advance groups, and the UE may associate the counters and parameters of the RACH procedure with the timing advance group. In other cases, the UE may associate the counters and parameters of the RACH procedure with multiple control resource set pool indexes which may correspond to multiple transmission reception points. Each set of counters may be associated with an uplink power control that the UE may use to determine the PRACH transmission power for each RACH procedure.

Abstract: Method and apparatus for PUSCH selection for UCI multiplexing. The apparatus determines that a transmission of UCI would at least partially overlap in time with transmissions of a set of PUSCHs. The set of PUSCHs including a plurality of PUSCHs on a same CC that are at least partially overlapping in time. The apparatus selects one PUSCH of the set of PUSCHs for multiplexing the UCI. The selection of the one PUSCH being based at least partially on a group association between the UCI and each PUSCH of the set of PUSCHs, or one or more transmission parameters of each PUSCH of the plurality of PUSCHs. The apparatus multiplexes the UCI on the selected one PUSCH for simultaneous transmission.

Abstract: An apparatus equipped with multiple antenna panels for wireless communication is provided. The apparatus receives a configuration message including a serving cell configuration and a bandwidth part configuration, wherein the serving cell configuration includes first timing advance information for a component carrier, and wherein the bandwidth part configuration includes second timing advance information for a bandwidth part of the component carrier. The apparatus transmits a first uplink signal (e.g., via a first antenna panel) to a first transmission reception point (TRP) using the bandwidth part based on at least a first timing advance value associated with the first timing advance information. The apparatus transmits a second uplink signal (e.g., via a second antenna panel) to a second TRP using the bandwidth part based on at least a second timing advance value associated with the second timing advance information.
