Patent ID: 8472467

Claim:
A multi-transceiver client device comprising: a first transceiver arranged to communicate with an access point over a first random-access channel and implement a random-access protocol for communications with the access point, the first random-access channel being one of a plurality of random-access channels in a first frequency spectrum designated for communications with access points; a second transceiver arranged to establish a low-latency radio link within a second frequency spectrum directly with a second client device; and processing circuitry arranged to determine first channel quality information indicative of channel conditions of the first random-access channel; wherein the second transceiver is arranged to receive second channel quality information from the second client device over the low-latency link during a contention phase of the random channel-access protocol for accessing the first random-access channel, the second channel quality information indicative of channel conditions of a second random-access channel, the second random-access channel being one of the plurality of random-access channels in the first frequency spectrum and being between the second client device and the access point, wherein the processing circuitry is to set a backoff delay for channel access on the first random-access channel based on both the first channel quality information and the second channel quality information, wherein the first and second frequency spectrums are non-overlapping spectrums.
