1. A wireless communications system, comprising:
- a first device configured to transmit signals in millimeter wave spectrum and receive signals in both millimeter wave spectrum and Sub-7 GHz spectrum, wherein millimeter wave and Sub-7 GHz receive antenna paths of the first device are combined into same receive ports through a first power combiner;
a second device configured to transmit signals in Sub-7 GHz spectrum and receive signals in both Sub-7 GHz spectrum and millimeter wave spectrum, wherein millimeter wave and Sub-7 GHz receive antenna paths of the second device are combined into same receive ports through a second power combiner,wherein the second device includes a sub-7 GHz transceiver where a receive port switches between a signal path from Sub-7 GHz spectrum and millimeter wave spectrum based on a composite switch control signal derived from transmit/receive status of a plurality of transceivers.
