Abstract
A wireless communication device including: a transmitter unit configured to transmit an RTS (Request To Send) packet to a plurality of wireless communication devices; a receiver unit configured to receive a CTS (Clear To Send) packet responding to the RTS packet; and a data processing unit configured to transmit data packets from the transmitter unit to the plurality of wireless communication devices when the CTS packet is received by the receiver unit from at least some of the plurality of wireless communication devices.
Claims14
An electronic device, comprising:
- circuitry configured to:
- transmit a multi-request to send (multi-RTS) signal to a first wireless communication device and a second wireless communication device,
- wherein the multi-RTS signal comprises identification information of the first wireless communication device and the second wireless communication device,
- receive a first clear to send (CTS) signal from the first wireless communication device or a second CTS signal from the second wireless communication device, wherein
- the first CTS signal is transmitted in response to the multi-RTS signal,
- the second CTS signal is transmitted with the transmission of the first CTS signal in response to the multi-RTS signal,
- the first CTS signal and the second CTS signal include a same training field,
- the first CTS signal is transmitted after a short inter-frame space (SIFS) from a first reception time of the multi-RTS signal at the first wireless communication device, and
- the second CTS signal is transmitted after the SIFS from a second reception time of the multi-RTS signal at the second wireless communication device;
- when the second CTS signal is not received, transmit a multiplexed data signal to the first wireless communication device and the second wireless communication device based on reception of the first CTS signal;
- and
- when the first CTS signal is not received, transmit the multiplexed data signal to the first wireless communication device and the second wireless communication device based on reception of the second CTS signal,
- wherein the multiplexed data signal includes first data for the first wireless communication device and second data for the second wireless communication device.
