Abstract: systems and methods for avoiding or mitigating cross-link interference in a time division duplexing (tdd) network are disclosed. in one embodiment, a method performed by a radio access network (ran) node comprises performing a baseline scheduling procedure for wireless communication devices for a slot, wherein the wireless communication devices are assigned first scheduling weights that correspond to priorities of the wireless communication devices for scheduling during the slot. the method further comprises determining that the slot is a downlink slot that is preceding an uplink slot and, responsive thereto, modifying the first scheduling weights based on whether the wireless communication devices are affected by cross-link interference to thereby provide second scheduling weights for the wireless communication devices for the slot. the method further comprises scheduling the wireless communication devices for the slot in accordance with the second scheduling weights.

Abstract: a first wireless communication device (), wcd, transmits a first indication to a second wcd () or receives a first indication from the second wcd. the first indication indicates a first time period () during which the first wcd is expected to monitor for receipt of a transmission. the first wcd monitors for receipt of a transmission during the first time period. the first wcd is not expected to monitor for receipt of a transmission during a second time period () before the first time period begins. the first wcd performs the transmission or receipt of the first indication after a link has been established between the first wcd and the second wcd for relaying of information to and/or from a network via one or more sidelink transmissions between the first wcd and the second wcd.
