RANDOM ACCESS CHANNEL OCCASIONS AND RESOURCES FOR INTERFERENCE MITIGATION
Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive a message scheduling a first resource for a downlink communication between a base station and the first UE, the first resource overlapping with a second resource for a random access channel (RACH) occasion (RO) for use by one or more second UEs. The first UE may receive the downlink communication over the first resource based on receiving the message, where the first resource is full-duplexed with the second resource of the RO and may transmit, over a third resource, an indication of cross link interference between a RACH message transmitted over the second resource and the downlink communication. The first UE may receive a second downlink communication over a fourth resource based at least in part on transmitting the indication.
