Claim 15:
16. A method, comprising:
determining, by a processing system including a processor, a coherence time and a coherence bandwidth for each user equipment (UE) of a plurality of UEs being served by a first cell, resulting in a plurality of coherence times and a plurality of coherence bandwidths;
responsive to the determining, identifying, by the processing system, a particular coherence block from the plurality of coherence times and the plurality of coherence bandwidths;
identifying, by the processing system, a sounding reference signal (SRS) sequence length based on the particular coherence block;
determining, by the processing system, a plurality of orthogonal SRS sequences based on the identifying the SRS sequence length; and
transmitting, by the processing system and to each neighboring cell of a plurality of neighboring cells adjacent to the first cell, a respective group of orthogonal SRS sequences from the plurality of orthogonal SRS sequences.
