Patent ID: 10075274

Abstract:
An Access Point (AP) 402 and a method therein for Multi-User Clear-To-Send (MU CTS) signaling between the AP and at least one wireless station (STA) 404,406. The AP sends a Request To Send (RTS) packet directed to multiple STAs. The RTS packet is indicating at least two STAs, to which the AP would like to transmit, and a configuration of a CTS packet to be used by said at least two STAs when responding to the RTS packet. The configuration enables the AP to identify the at least two STAs when the at least two STAs are transmitting a respective CTS packet. Further the AP receives, from at least one STA, a respective CTS packet transmitted in accordance with the indicated configuration, thereby enabling the AP to identify the at least one STA transmitting the respective CTS packet.
