Method and system for orthogonal pilot signaling

A device, comprising:

• a processing system including a processor, wherein the processing system is communicatively coupled with a plurality of coherent modular antenna panels;
• and
• a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
• tracking coherence times and coherence bandwidths for a plurality of user equipment (UEs) that are served by a first cell via the plurality of coherent modular antenna panels;
• identifying a particular pilot sequence length based on the tracking the coherence times and the coherence bandwidths;
• responsive to the identifying the particular pilot sequence length, generating a plurality of orthogonal pilot sequences;
• determining a number of cells in which any given pilot sequence of the plurality of orthogonal pilot sequences is not to be reused;
• identifying a plurality of neighboring cells adjacent to the first cell based on the determining the number of cells;
• and
• providing, to each neighboring cell of the plurality of neighboring cells, a respective subset of orthogonal pilot sequences of the plurality of orthogonal pilot sequences.

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.
