Systems and methods for managing coexistence in wireless communication devices

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, and
• select (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.
