Claim 0:
1. First network equipment, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
determining respective port numbers for respective ranks of a first transmission to a user equipment, wherein the determining comprises partitioning respective indices of the respective port numbers between the first network equipment and second network equipment based on a rank of the respective ranks being determined to be a rank 1 and based on a first network traffic load of the first network equipment and a second network traffic load of the second network equipment;
exchanging, with the second network equipment, information related to a maximum rank and a port number for each rank;
receiving an indication, from the second network equipment, of a first demodulation reference signal associated with a first port number for a rank of a second transmission to the user equipment from the second network equipment;
facilitating a conveyance of the first transmission to the user equipment, wherein the first transmission comprises a second demodulation reference signal on a second port number, different than the first port number associated with the second transmission, and wherein the exchanging comprises determining that the first demodulation reference signal is not scheduled on a first resource element, associated with a first phase tracking reference signal and assigned to the first network equipment and that the second demodulation reference signal is not scheduled on a second resource element, associated with a second phase tracking reference signal different than the first phase tracking reference signal and assigned to the second network equipment, and wherein the first phase tracking reference signal and the second phase tracking reference signal are configured to track respective phase variations across respective durations of the first transmission and the second transmission; and
performing semi-static coordination with transmissions of the second network equipment, wherein the performing comprises sending, to the second network equipment, indications of tracking reference signal (TRS) resource elements assigned to the first network equipment, and a periodicity of the TRS.
