Claim of US Patent No. 10,485,026

1. An electronic device, comprising:circuitry configured to:
transmit a multi-request to send (multi-RTS) packet to at least a first wireless communication device and a second wireless communication device,
wherein the multi-RTS packet comprises identification information of the first wireless communication device and the second wireless communication device,
wherein the first wireless communication device transmits, in response to the multi-RTS packet, a first clear to send (CTS) packet and the second wireless communication device transmits, in response to the multi-RTS packet, a second CTS packet simultaneously with the transmission of the first CTS packet, and
wherein the first CTS packet and the second CTS packet include a same training field;
receive at least one of the first CTS packet from the first wireless communication device or the second CTS packet from the second wireless communication device,
wherein the first wireless communication device transmits the first CTS packet after a short inter-frame space (SIFS) from a first reception time instance of the multi-RTS packet at the first wireless communication device, and
wherein the second wireless communication device transmits the second CTS packet after the SIFS from a second reception time instance of the multi-RTS packet at the second wireless communication device; and
transmit a multiplexed data packet to the two first wireless communication device and the second wireless communication device, based on reception of the at least one of the first CTS packet or the second CTS packet,
wherein the multiplexed data packet includes a first data packet for the first wireless communication device and a second data packet for the second wireless communication device.
