Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration associated with an orthogonal cover code (OCC), wherein the configuration indicates a multiplexing order, an OCC codeword for multiplexing, and a type of OCC, and the type of OCC is one of: frequency domain OCC (FD-OCC), time domain OCC (TD-OCC), sub physical resource block (sub-PRB) OCC, or sub-slot OCC. The UE may apply, based at least in part on the configuration, the OCC to an uplink transmission. The UE may transmit the uplink transmission with the OCC applied based at least in part on the configuration. Numerous other aspects are described.

Abstract: Aspects are provided which resolve neighbor beam-wise interference. A UE obtains a plurality of reference signals from each of at least one neighbor base station, where each of the reference signals is obtained in a different beam, and each of the neighbor base station(s) is in a different neighbor cell. The UE then measures a signal strength associated with each of the reference signals, and the UE indicates one or more of the reference signals to a serving base station in a serving cell, where the signal strength of each of the reference signal(s) indicated to the serving base station exceeds a threshold RSRP. After the serving base station obtains the indication from the UE, the serving base station coordinates with the neighbor base station(s) to modify one or more transmission parameters in response to the indication.

Abstract: Certain aspects of the present disclosure provide techniques for bandwidth part (BWP) switching by frequency shifting and/or by transmission configuration indicator (TCI) state configuration. A method that may be performed by a user equipment (UE) includes receiving a BWP configuration indicating a frequency location and bandwidth of at least a first BWP; receiving signaling indicating at least one frequency shift to determine a second BWP from a frequency location of the first BWP; and communicating on the second BWP after performing a BWP switch from the first BWP to the second BWP based on the at least one frequency shift.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE) generally including receiving signaling indicating one or more values for a scheduling offset between a downlink slot where downlink control information (DCI) is received and an uplink slot for transmitting a physical uplink shared channel (PUSCH) scheduled by the DCI; determining an additional offset to be used in conjunction with the scheduling offset values to determine PUSCH transmission timing; determining a power control adjustment for a sounding reference signal (SRS) transmission based on transmission power control (TPC) commands received in a time interval determined by one of the scheduling offset values and the additional offset; and transmitting SRS in an SRS transmission occasion, in accordance with the determined power control adjustment.
