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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a number of bits to be used in a downlink control information (DCI) message, the bits configured to indicate a transmission reception point (TRP) mode configuration for one or more subsequent communications. The UE may receive the DCI message having the number of bits to indicate the TRP mode configuration for the subsequent communications. Numerous other aspects are described.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a timing advance value to use for an uplink transmission based on a unified transmission configuration indicator (TCI) state associated with the uplink transmission. In some examples, the control signaling configuring a unified TCI state for an uplink transmission may indicate the timing advance value for the uplink transmission. In some examples, the UE may receive control signaling indicating an association between a set of timing advance values for the component carrier associated with a set of unified TCI states or a set of unified TCI groups, and the UE may determine the timing advance value for a given uplink transmission based on the TCI state or TCI group indicated for the uplink transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node associated with a first transmit-receive point (TRP) identifier (ID) and a second TRP ID, an uplink repetition configuration comprising a first mapping between the first TRP ID and a first uplink repetition component and a second mapping between the second TRP ID and a second uplink repetition component. The UE may transmit a first uplink transmission corresponding to the first TRP ID based at least in part on the first mapping. The UE may transmit a second uplink transmission corresponding to the second TRP ID based at least in part on the second mapping. Numerous other aspects are described.
