Patent ID: 11105916

Abstract:
An access point (AP) device of a wireless communication network determines that an unassociated client station requests to participate in a ranging measurement procedure with the AP device, and determines a preliminary network ID for uses by the unassociated client station during a ranging measurement session and while the unassociated client station remains unassociated with the wireless communication network. The AP device transmits a packet having the preliminary network ID, and after transmitting the packet having the preliminary network ID, participates in a multi-user (MU) null data packet (NDP) ranging measurement session with a plurality of client stations that includes the unassociated client station. Participating in the MU NDP ranging measurement session includes transmitting a trigger frame to prompt the plurality of client stations to simultaneously transmit respective NDPs as part of an uplink MU transmission corresponding to the MU NDP ranging measurement session, where the trigger frame includes the preliminary network ID.
