Disclosed is a method of transmitting a demodulation reference signal (DMRS) by a user equipment (UE) using carrier aggregation, including transmitting, over a first component carrier (CC), a first transmission using a first power and a second transmission using a third power; and transmitting, over a second CC and simultaneously with the first transmission and the second transmission over the first CC, a first transmission using a second power and a second transmission using a fourth power, wherein a sum transmission power across the first and second CCs is maintained during an entire DMRS bundling duration.

Managing use of dynamic power sharing for dual carrier operation is provided. An allowed tolerance is identified (802) corresponding to a maximum expected possible deviation between a power level at which the user equipment requests that a communication via the master cell group be set and an actual power level at which the corresponding communication via the master cell group is transmitted. A lower bound of a maximum configured power of the secondary cell group is determined (804), which enables the user equipment to meet emission requirements during the dual carrier operation, as well as the total power constraints for any overall communications of the user equipment, while accounting for the allowed tolerance identified. The lower bound of the maximum configured power for the carrier of the secondary cell group is set (806) at the determined level.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating an uplink gap. The UE may transmit a reference signal in the uplink gap. The UE may perform at least one of a self-interference measurement or a beam pair calibration for full-duplex communication based at least in part on the reference signal. Numerous other aspects are described.

Methods, apparatuses, and computer-readable medium for soft cancellation of sidelink transmissions are provided. An example method may include receiving, from a base station, DCI comprising at least one of: an open loop power control parameter, a maximum transmit power, or a closed loop power control parameter. The open loop power control parameter, the maximum transmit power, or the closed loop power control parameter may be associated with a PSSCH or a PSCCH. The example method may further include reducing a transmit power of a scheduled transmission associated with the PSSCH or the PSCCH to a reduced transmit power if the reduced transmit power is above a threshold or cancel the scheduled transmission if the reduced transmit power is below the threshold. The reduced transmit power may be based on the open loop power control parameter, the maximum transmit power, or the closed loop power control parameter.
