Coordinated medium access period management for overlapping basic service sets
This disclosure provides methods, components, devices and systems for coordinated medium access period management for overlapping basic service sets (OBSSs). Some aspects more specifically relate to coordinated medium access between access points (APs) and stations (STAs) of an OBSS. In some examples, a first STA may monitor, over one or more medium access periods, for communications between a neighbor AP and one or more second STAs. The one or more medium access periods may be configured for medium access and resource reservation for communications between the neighbor AP and the one or more second STAs. In some examples, the first STA may transmit to an associated AP, a report indicating the one or more attributes associated with the monitoring over the one or more medium access periods. In some examples, the report may be solicited or unsolicited, and the STA may monitor for communications over one or more measurement windows.
