Abstract
Computing readable media, apparatuses, and methods for spatial reuse with training in RTS-CTS are disclosed. An apparatus comprising processing circuitry is disclosed. The processing circuitry configured to: decode a received frame, the frame including either a request to send (RTS) frame or a clear to send (CTS) frame, with an initial portion of the frame indicating a plurality of training fields (TRN-R) at an end of the frame. The processing circuitry further configured to perform a clear channel assessment (CCA) for each receive (Rx) sector of a plurality of Rx sectors using the plurality of TRN-Rs.
Claims25
An apparatus of a wireless device, the apparatus comprising:
- memory;
- and processing circuitry coupled to the memory, the processing circuitry configured to:
- decode a received frame, the frame comprising either a request to send (RTS) frame or a clear to send (CTS) frame, an initial portion of the frame indicating a plurality of training fields (TRN-R) at an end of the frame;
- and
- perform a clear channel assessment (CCA) for each receive (Rx) sector of a plurality of Rx sectors using the plurality of TRN-Rs.
A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors, the instructions to configure the one or more processors to cause an apparatus of a wireless device to:
- decode a received frame, the frame comprising either a request to send (RTS) frame or a clear to send (CTS) frame, an initial portion of the frame indicating a plurality of training fields (TRN-R) at an end of the frame;
- and
- perform a clear channel assessment (CCA) for each receive (Rx) sector of a plurality of Rx sectors using the plurality of TRN-Rs.
A method performed by a wireless device, the method comprising:
- decoding a received frame, the frame comprising either a request to send (RTS) frame or a clear to send (CTS) frame, an initial portion of the frame indicating a plurality of training fields (TRN-R) at an end of the frame;
- and
- performing a clear channel assessment (CCA) for each receive (Rx) sector of a plurality of Rx sectors using the plurality of TRN-Rs.
An apparatus comprising memory;
- and processing circuitry coupled to the memory, the processing circuitry configured to:
- encode a request to send (RTS) or a clear to send (CTS) and a plurality of training fields (TRN-R) at the end of the CTS or RTS;
- and
- configure a wireless device to transmit the RTS or the CTS and the plurality of TRN-R in a directional way to a second wireless.
