Classification: CPC H  Y | IPC H

Claim 15:
16. A method for performing a synchronization to allow a second wireless communication circuit of a wireless device operating in a second wireless communication network to operatively coexist with a first wireless communication circuit of the wireless device operating in a first wireless communication network in one or more wireless communication channels according to a time division multiplexing (TDM) plan, wherein the method comprises:
determining whether the one or more wireless communication channels are busy comprising determining whether a packet has been detected by the wireless device in the one or more wireless communication channels, or determining whether the wireless device has sensed energy in the one or more wireless communication channels when one or more back-off counters associated with the TDM plan is zero; and
granting to the second communication circuit, in response to determining the one or more wireless communication channels are busy, use of the one or more wireless communication channels,
wherein determining whether a packet has been detected by the wireless device in the one or more wireless communication channels comprises determining whether a network allocation vector (NAV) time for the one or more wireless communication channels is nonzero, and
wherein determining whether the wireless device has sensed energy in the one or more wireless communication channels when one or more back-off counters associated with the TDM plan is zero comprises performing a clear channel assessment (CCA) to determine whether the one or more wireless communication channels are busy.
