Synchronization of co-located radios in a dynamic time division duplex system for interference mitigation
First Claim
1. A method for operating a first of a plurality of co-located, non-time synchronous radios at a first location communicating data by frames with one or more other remote radios at a second and optionally additional locations in a wireless communication system, to synchronize first or uplink and/or second or downlink frame portions of the frames to mitigate interference between the co-located radios, comprising:
- storing a frame table of attributes of uplink and/or downlink frame portions associated with frames of the first radio;
wirelessly receiving at the first radio RF transmissions from at least a second of the co-located radios;
monitoring by the first radio the spectral content of the RF transmissions from the at least second co-located radio;
determining by the first radio, based on the monitored spectral content, characteristics for uplink and/or downlink frame portions of the first co-located radio to mitigate interference with the at least second co-located radio; and
updating attributes in the frame table to enable interference-optimized uplink and/or downlink portions of frames of the first co-located radio.

Abstract
A method for operating at least a first of a plurality of co-located, non-time synchronous radios at a first location communicating data by frames with one or more other remote radios at a second and optionally additional locations in a wireless communication system, to synchronize first or uplink and/or second or downlink frame portions of the frames to mitigate interference between the co-located radios. A frame table of attributes of uplink and/or downlink frame portions associated with frames of the first radio is stored. The spectral content of transmissions from at least a second of the co-located radios is monitored. Based on the monitored spectral content, characteristics for uplink and/or downlink frame portions of the first co-located radio to mitigate interference with the at least second co-located radio are determined. Attributes in the frame table to enable interference-optimized uplink and/or downlink portions of frames of the first co-located radio are updated.
