Abstract

Disclosed are techniques for wireless communication. In an aspect, one or more slots in a set of DMRS-bundled slots are excluded from a DMRS-sharing power control configuration based on duplex-type. In another aspect, a fixed transmission power level for a DMRS-sharing power control configuration is based at least in part upon a duplex configuration of DMRS-bundled slots.

a memory;

at least one transceiver; and

at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:

bundle a set of slots for transmissions in accordance with a demodulation reference signal (DMRS)-sharing power control configuration that maintains phase continuity by sharing DMRS to fix transmission power for the transmissions across the set of slots;

determine a first transmission power level for a first transmission of first data associated with a first duplex type on a first slot of the set of slots in accordance with the DMRS-sharing power control configuration;

transmit, via the at least one transceiver, an indication that full-duplex transmissions during the set of slots are excluded from the DMRS-sharing power control configuration.
