SYSTEMS AND METHODS FOR MANAGING COEXISTENCE IN WIRELESS COMMUNICATION DEVICES

摘要

A wireless communication device first and second transceivers to transmit in respective first and second frequency bands. The device includes an arbiter to map the first frequency band into a plurality of regions and sub-regions and map a plurality of channels to the sub-regions, and a first controller to select one of the plurality of sub-regions and inform the arbiter of the selected one of the plurality of sub-regions. The arbiter is further to select a first group of channels in the second frequency band when the selected one of the plurality of sub-regions is a first sub-region, select a second group of channels in the second frequency band when the selected one of the plurality of sub-regions is a second sub-region, and select a third group of channels in the second frequency band when the selected one of the plurality of sub-regions is a third sub-region.

主权项

1. A wireless communication device, comprising:
a first transceiver to transmit and receive first signals according to a first protocol, wherein the first protocol is associated with a first frequency band; a second transceiver to transmit and receive second signals according to a second protocol, wherein the second protocol is associated with a second frequency band adjacent to the first frequency band; an arbiter to (i) map the first frequency band into a plurality of regions, (ii) map the plurality of regions to a plurality of sub-regions such that each region includes a plurality of the sub-regions, and (iii) map a plurality of channels in the first frequency band to the sub-regions; and a first controller associated with the first transceiver, the first controller to (i) select one of the plurality of sub-regions, and (ii) inform the arbiter of the selected one of the plurality of sub-regions, wherein the first transceiver is further to transmit and receive the first signals in a first channel of the plurality of channels corresponding to the selected one of the plurality of sub-regions, wherein the arbiter is further to
(i) map a first sub-region of the plurality of sub-regions to a first group of channels available in the second frequency band, (ii) map a second sub-region of the plurality of sub-regions to a second group of channels available in the second frequency band, and (iii) map a third sub-region of the plurality of sub-regions to a third group of channels available in the second frequency band, andselect (i) the first group of channels in the second frequency band when the selected one of the plurality of sub-regions is the first sub-region, (ii) the second group of channels in the second frequency band when the selected one of the plurality of sub-regions is the second sub-region, and (iii) the third group of channels in the second frequency band when the selected one of the plurality of sub-regions is the third sub-region, and wherein the second transceiver is further to transmit and receive the second signals only in the selected first group, second group, or third group.
