1. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processing system associated with a first cell and including a processor, facilitate performance of operations, the operations comprising:
determining a coherence time and a coherence bandwidth for each user equipment (UE) of a plurality of UEs being served by the first cell, resulting in a plurality of coherence times and a plurality of coherence bandwidths;
responsive to the determining, identifying a coherence block from the plurality of coherence times and the plurality of coherence bandwidths;
identifying a pilot sequence length based on the coherence block;
determining a plurality of orthogonal pilot sequences based on the identifying the pilot sequence length; and
distributing, to each neighboring cell of a plurality of neighboring cells adjacent to the first cell, a respective group of orthogonal pilot sequences from the plurality of orthogonal pilot sequences.
