Spatial reuse clear to send (CTS) within wireless communications

摘要

A wireless communication device (alternatively, device) includes a processing circuitry configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other wireless communication device(s) and to generate and process signals for such communications. A device receives a request to send (RTS) from another device and replies with a clear to send (CTS) when the RTS includes a non-zero-valued network allocation vector (NAV) if one or more conditions make such a response permissible. The device processes other parameter(s) associated with other communications between other devices to determine if a CTS response is permissible even during the other communications between the other devices. If comparison of the other parameter(s) is/are favorably to certain condition(s), the device transmits the CTS.

主权项

1. A wireless communication device comprising:
a processing circuitry configured to:
receive, from a first other wireless communication device, a request to send (RTS) that is modulated within a sub-channel of a communication channel;process the RTS to determine whether the RTS is intended for the wireless communication device and whether the RTS includes a network allocation vector (NAV) having a non-zero value;when it is determined that the RTS is intended for the communication device and the NAV of the RTS has the non-zero value, process one or more parameters associated with first communications between a second other wireless communication device and a third other wireless communication device to determine whether second communications between the wireless communication device and the first other wireless communication device are permissible; andwhen it is determined that the second communications between the wireless communication device and the first other wireless communication device are permissible, generate and transmit a clear to send (CTS) to the first other wireless communication device.
