1. A first access point comprising circuitry configured to
communicate with one or more first stations associated with the first access point,
transmit a trigger requesting stations to transmit data units containing channel estimation sequences enabling channel estimation and/or channel feedback information,
determine channel information based on channel estimation sequences and/or the channel feedback information transmitted from one or more of said first stations and from one or more second stations associated with a second access point, and
determine, based on the determined channel information, spatial reuse parameters for use by the first access point for reception of data during spatial reuse of resources by (i) one or more of said first stations for transmission of data to the first access point and (ii) by one or more of said second stations for transmission of data to the second access point.
