Abstract:
A method for communication includes accessing all sub-channels in a communication frame, generating a counter that counts down beginning with a received first listen before talk (LBT) communication symbol, determining whether the counter reaches zero before receiving a second LBT communication symbol, determining whether a desired number N of contiguous sub-channels are available, and if the desired number N of contiguous sub-channels are available, transmitting an LBT symbol.
