Dynamic time division duplex (TDD) is a flexible transmission technique allowing different user equipments (UEs) to operate in a downlink mode or an uplink mode depending on the instantaneous traffic load. As a result, a UE transmitting on an uplink channel may interfere with a neighboring UE receiving on a downlink channel. UEs may coordinate communication parameters to reduce cross-link interference. A UE may determine a preferred value(s) for a first communication parameter comprising a beam direction or a slot format index (SFI). The UE receives a candidate value(s) for the first communication parameter, the candidate value(s) being based on communications between a second UE and a first base station. The UE selects a first value among the preferred values based on the received candidate value(s); and initiates communications with a second base station using the first value for the first communication parameter.
