Claim of US Patent No. 10,924,214

4. A method operable with a wireless communication system operating in a Radio Frequency (RF) band with a conflicting WiFi system, the method comprising:receiving uplink communications from a user equipment (UE) in the RF band via a wireless base station;
estimating a location of the UE based on the uplink communications;
determining a communication capability between the UE and the wireless base station based on the location of the UE; and
downgrading downlink communications from the wireless base station to the UE based on the communication capability to avoid interference with the WiFi system;
wherein:
the communication capability includes a location of the UE within an antenna directional radiation pattern of the wireless base station, and
downgrading downlink communications includes utilizing the antenna directional radiation pattern according to the location of the UE within the antenna directional radiation pattern of the wireless base station, to avoid interference with the WiFi system.
