A wireless apparatus node supporting wireless communications on a wireless local area network (WLAN). The wireless apparatus node includes: a local link prober, a remote link prober, a cross-link interference estimator, and a concurrent access controller. The local link prober probes a target node for channel information characterizing a communication channel for a local link therewith. The remote link prober probes a pair of device nodes on the WLAN capable of forming a remote link for cross-channel information characterizing communication channels there between. The cross-link interference estimator estimates interference signal levels at each node of the remote link resulting from communication over the local link. The concurrent access controller is responsive to a determination of an active communication on the remote link to allow a concurrent communication on the local link when interference levels at the remote link fall below a threshold level.
