Claim 8:
9. A method, comprising:
determining, by first network equipment of a group of network equipment, respective port numbers for ranks of a group of ranks, wherein the first network equipment comprises a processor;
based on a rank of the group of ranks being a rank 1 and based on a first network traffic load of the first network equipment and a second network traffic load of second network equipment of the group of network equipment, partitioning, by the first network equipment, respective indices of the respective port numbers;
exchanging, by the first network equipment and with the second network equipment, information related to a maximum rank and a port number for each rank;
receiving, by the first network equipment, information indicative of respective demodulation reference signal ports for the ranks of the group of ranks, wherein the information is received from the second network equipment;
reserving, by the first network equipment, first resource elements of the respective demodulation reference signal ports for use by the second network equipment;
scheduling, by the first network equipment, data transmissions on second resource elements of the respective demodulation reference signal ports while avoiding the first resource elements, wherein the second resource elements are associated with phase tracking reference signals;
transmitting, by the first network equipment, data to a mobile device based on the mobile device being scheduled with the respective port numbers, wherein the phase tracking reference signals are configured to monitor phase variations during the transmitting; and
facilitating, by the first network equipment, semi-static coordination with transmissions of the second network equipment, wherein the semi-static coordination comprises conveying, 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.
