A user equipment (UE) or base station may be capable of operating using two or more timing configurations that each include an associated time period between receipt of a downlink communication (e.g., a grant of uplink resources or shared channel data) and a responsive uplink communication (e.g., an uplink transmission using the granted uplink resources or feedback of successful reception of the shared channel data). In cases where a UE or base station are capable of two or more timing configurations, a timing configuration for a transmission may be determined and the responsive uplink communication transmitted according to the determined timing configuration.

Abstract: During a first P3 sweep that is associated with a first TCI state and during a second P3 sweep that is associated with a second TCI state, the UE stores the RSRP for each UE RX beam for each UE panel. Then, when the UE is scheduled for a downlink transmission through a DCI pointing to two these two TCI states, instead of only selecting the UE RX beam for respective panel based on the highest RSRP, the UE also takes the hypothetical inter-stream interference in to account when selecting the UE RX beams.

Wireless communications systems may support uplink random access channel (RACH) transmissions on multiple beams and over multiple component carriers (CCs).
