Patent ID: 8855079

Claim:
A first network device comprising: a first physical layer device configured to, in accordance with a first wireless communication standard, transfer first data on a first channel between the first network device and a second network device via a base station; a second physical layer device configured to, in accordance with a second wireless communication standard, (i) receive a first request transmitted to the first network device on a second channel, wherein the first request is received from the second network device via an access point, wherein the first request requests permission for the second network device to send second data to the first network device, and wherein the second wireless communication standard is different than the first wireless communication standard, and (ii) in response to receiving the first request from the second network device, determine whether the first physical layer device is receiving the first data from the second network device, wherein the second physical layer device is configured to, if the first physical layer device is not receiving the first data, determine whether the first physical layer device is to (i) receive the first data from the second network device in a first predetermined period, or (ii) transmit the first data to the second network device in a second predetermined period, the second physical layer device is configured to transmit a response signal to the second network device, on the second channel and via the access point, if the first physical layer device is not to (i) receive the first data from the second network device in the first predetermined period, or (ii) transmit the first data to the second network device in the second predetermined period, wherein the response signal indicates permission to send the second data, the first physical layer device is configured to transmit a first signal to or receive the first signal from the second network device on the first channel via the base station, and the second physical layer device is configured to, while the first physical layer device is transmitting or receiving the first signal, transmit a second signal to or receive the second signal from the second network device on the second channel via the access point; and a control module configured to (i) determine whether there is interference between the first signal and the second signal, and (ii) in response to determining that interference exists between the first signal and the second signal, select a third channel, wherein the third channel is different than the first channel and the second channel.
