Claim 16:
17. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of first network equipment, facilitate performance of operations, comprising:
determining respective port numbers for respective ranks of a first transmission to a user equipment;
based on respective network loads of first network equipment and second network equipment and based on a rank of the respective ranks being a rank 1, partitioning respective indices of the respective port numbers between the first network equipment and the second network equipment;
exchanging, with the second network equipment, information related to a maximum rank and a port number for each rank of the respective ranks;
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;
sending 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, wherein the sending comprises sending data using assigned resource elements other than resource elements assigned to the second network equipment, wherein first phase tracking reference signals of the assigned resource elements are configured to track first phase variations across a first duration of the first transmission, and wherein second phase tracking reference signals of the resource elements assigned to the second network equipment are configured to track second phase variations across a second duration of the second transmission; and
performing semi-static coordination with transmissions of the second network equipment, wherein the performing comprises transmitting, 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.
