1. A method of wireless communication performed by a network entity, comprising:
identifying a collision between a data transmission and a demodulation reference signal (DMRS) transmission in a full-duplex time-frequency resource;
determining a time-frequency mapping for a zero-power DMRS (ZP-DMRS) in the full-duplex time-frequency resource based at least in part on the identified collision; and
transmitting, to a wireless communication device, an indication of the time-frequency mapping for the ZP-DMRS in the full-duplex time-frequency resource,
wherein the time-frequency mapping for the ZP-DMRS, and a time-frequency mapping in the full-duplex time-frequency resource for the DMRS transmission, are a same time-frequency mapping.
