Patent ID: 8331418

Claim:
A method of communication by a first wireless device operating according to a first communication protocol in at least a first set of frequency bands, wherein one or more of the frequency bands in the first set overlaps at least a portion of a second set of one or more frequency bands on which a second wireless device operates according to a second communication protocol, the method comprising: (1) dividing a time cycle into a plurality of subcycles, each subcyle having a period long enough for the second wireless device to receive a first signal according to the second communication protocol and to transmit a second signal according to the second communication protocol; (2) in each of the subcycles, selecting one of a plurality of logical channels available to the first wireless device, each logical channel employing a corresponding hopping sequence for frequency hopping among a subset of the frequency bands in the first set; (3) transmitting from the first wireless device a signal according to the first communication protocol in each of the subcycles, using the selected logical channel for that subcycle; and (4) repeating steps (1) to (3) over a plurality of time cycles; wherein in each time cycle, each frequency band of the first set that overlaps at least a portion of the second set of frequency bands is excluded in at least one of the hopping sequences employed by at least one of the logical channels selected in at least one of the subcycles.
