Abstract: A device including a first transceiver and a second transceiver. The first transceiver is configured to selectively transmit and receive first signals in a first frequency band according to a schedule. The first signals include at least cellular signals. The second transceiver is configured to selectively transmit and receive second signals in a second frequency band different from the first frequency band. The second signals include at least WiFi signals. An arbiter is configured to generate status reports indicating statuses of channels in the first frequency band and/or the second frequency band, receive the schedule as generated based on the statuses, and selectively modify the status reports based on an expected transmission and/or reception of the first signals by the first transceiver, and/or an expected transmission and/or reception of the second signals by the second transceiver.

Abstract: A device including a transmitter, a receiver and an arbiter. The transmitter transmits a first signal. The first signal has a fundamental frequency in a first frequency band of a first wireless protocol. The receiver receives a second signal. The second signal has a fundamental frequency in a second frequency band of a second wireless protocol. The first frequency band is adjacent to or at least partially overlaps the second frequency band. The arbiter allows the transmitter to transmit the first signal in the first frequency band while the receiver receives the second signal in the second frequency band. The arbiter also, if a power level of the first signal is less than a first threshold, changes: a modulation and coding scheme of the transmitter for the first signal; a modulation and coding scheme of the receiver for the second signal; or a multiple input and multiple output rank.

Abstract: In a wireless communication system including a plurality of client stations including at least one client station that is not configured to utilize carrier aggregation, different coverage areas correspond to different frequency bands being utilized. Wireless medium resources are allocated and frequency band(s) are assigned, jointly, to the client stations based on one or more coverage areas corresponding to one or more frequency bands in which each client station is located, whether client stations are configured to utilize carrier aggregation, demand factors, and indications of channel quality.
