Abstract: Certain aspects of the present disclosure provide techniques for interference management reference signal (RS) transmission. An example method, performed at a first network entity, generally includes applying a frequency domain function to a first copy of a first reference signal (RS) sequence to obtain a modified first copy of the first RS sequence, and outputting, to a second network entity, frequency domain samples of the modified first copy of the first RS sequence and frequency domain samples of a second copy of the first RS sequence.

Abstract: Various aspects described herein relate to resolving failures in digital pre-distortion (DPD) training in wireless communications. A failure during DPD training can be identified for a transceiver. One or both of a severity of the failure or a type of the failure can be determined. It can also be determined whether to perform self-recovery from the failure to continue the DPD training based at least in part on one or both of the severity of the failure or the type of the failure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to initiate a random access channel (RACH) procedure with a base station (BS). The UE may determine, based at least in part on determining to initiate the RACH procedure, whether a timing alignment timer, associated with a timing alignment of the UE and the BS, is expired. The UE may initiate the RACH procedure using the timing alignment based at least in part on determining that the timing alignment timer is not expired. Numerous other aspects are provided.

Abstract: Various aspects described herein relate to adjusting transmit power of a radio frequency (RF) transceiver. A total power adjustment for adjusting a transmit power of the RF transceiver can be determined. The transmit power can be adjusted to a first adjusted transmit power based at least in part on a first adjustment size that is less than the total power adjustment and determined based at least in part on the transmit power. Digital pre-distortion (DPD) training of the RF transceiver can be performed to adjust one or more coefficients for calibrating the RF transceiver based on the first adjusted transmit power. The first adjusted transmit power can be adjusted to a second adjusted transmit power based at least in part on a second adjustment size that is less than the total power adjustment and computed based at least in part on the first adjusted transmit power.
