Patent ID: 10727912

Abstract:
A communication device of a client uplink group transmits an enhanced request to send (E-RTS) message to an access point of a wireless local area network, wherein the E-RTS message includes i) a length of a TXOP of the communication device and ii) an indication of a data unit size for an uplink MU-MIMO data unit to be transmitted by the communication device simultaneously with transmissions of other members of the client uplink group. The communication device receives a communication frame from the access point, the communication frame including a prompt to transmit an uplink MU-MIMO data unit having the indicated data unit size. The communication device generates the uplink MU-MIMO data unit having the indicated data unit size, and transmits, in response to the communication frame, the uplink MU-MIMO data unit to the access point during the TXOP simultaneously with transmissions of other members of the client uplink group.
