1. A baseband processor of a wireless user equipment (UE) of a communication network exposed to intra-cell cross link interference (CLI) comprising:
receiving, from the communication network, a signaling identifying resources scheduled for use by one or more interfering UEs of the communication network for one or more uplink transmissions, the uplink transmissions to be measured to indicate a level of the intra-cell CLI from the interfering UEs when the UE receives a downlink transmission from the communication network;
receiving, from the interfering UEs, the uplink transmissions carried on the resources identified;
determining the level of the intra-cell CLI based on the uplink transmissions to generate a CLI measurement; and
transmitting the CLI measurement to the communication network to indicate the level of the intra-cell CLI from the interfering UEs,
wherein transmitting the CLI measurement to the communication network comprises transmitting the CLI measurements using a same uplink resource allocated to the UE to transmit an acknowledgement that the downlink transmission is received in error.
