A first network device includes a first PHY device that transfers first data on a first channel between the first network device and a second network device via a base station. The second PHY device receives a first request transmitted on a second channel and in response to receiving the first request, determines whether the first PHY device is receiving the first data. The first request is received from the second network device via an access point and requests permission to send second data. The second PHY device, if the first PHY device is not receiving the first data, determines whether the first PHY device is to receive or transmit the first data in respective periods. The second PHY device transmits a response signal to the second network device, on the second channel, if the first PHY device is not to receive or transmit the first data the respective periods. |
