1. A cellular communication system comprising:
a plurality of base stations, the plurality of base stations defining a coverage area and including:
at least one corresponding base station receiver;
a plurality of user equipment devices (UEs), each of the plurality of UEs including:
a transceiver in data communication with at least one of the plurality of base stations;
a memory storing values received via the transceiver from at least one base station, the values including a tone descriptor and a time;
a controller communicatively coupled to each of the plurality of base stations in the coverage area, the controller including executable instructions that cause the controller to:
calculate a unique tone value for at least some of the plurality of UEs; and
cause each unique tone to be transmitted to its corresponding UE via the plurality of base stations;
cause each of the some of the plurality of UEs to broadcast its unique tone at a specified time and power level;
collect data from each of the plurality of base stations corresponding to receipt of the broadcast of the unique tones, the data including:
an identity of each UE from which a corresponding unique tone was received;
an identity of one or more base stations receiving the corresponding unique tone;
a received power level of each unique tone at each of the one or more base stations receiving the corresponding unique tone;
generate a reception pattern of the coverage area; and
update channel access values for each of the plurality of base stations according to the generated reception pattern.
