Abstract:
1. A method for communicating in a wireless network, the method comprising: receiving, by a communications device, beacons from a plurality of primary protecting devices, where each of the plurality of primary protecting devices are associated with a different one of a plurality of wireless networks; demodulating the beacons to produce spread symbols; analyzing the spread symbols to determine which sequences in a list of orthogonal sequences are being used by the primary protecting devices, wherein each of the sequences in the list of orthogonal sequences are orthogonal to one another, and wherein each of the plurality of primary protecting devices use a different sequence in the list of orthogonal sequences; and establishing, by the communications device, a new wireless network for communicating unlicensed transmissions by selecting an unused orthogonal sequence from the list of orthogonal sequences, and transmitting a new beacon in accordance with the selected orthogonal sequence.
