Abstract
Because the number of transmitted layers can vary dynamically, the number of transmitted demodulation reference signals (DM-RS) can also vary. However, because the network node can know the number of ports, transmitted layers, or the rank, the network node can utilize the number as part of the scheduling information via a downlink or an uplink control channel. Therefore, the DMRS sequence generation can modified such that it depends on the number of ports, transmitted layers, or the rank, thereby generating a different random sequence for different ports.

A method, comprising:
- based on rank data, selecting, by network equipment comprising a processor, a first network port to be used in a network transmission;
- based on port data associated with the first network port, generating, by the network equipment, a randomized demodulation reference signal sequence that is different than a previously utilized demodulation reference signal sequence that is associated with a second network port;
- in response to generating the randomized demodulation reference signal sequence, precoding, by the network equipment, the randomized demodulation reference signal sequence, resulting in precoded demodulation reference signal sequence data representative of a precoded demodulation reference signal sequence;
- multiplexing, by the network equipment, a resource element by a code, resulting in a code multiplexed resource element;
- and
- in response to precoding the randomized demodulation reference signal sequence, transmitting, by the network equipment via the first network port, the precoded demodulation reference signal sequence data to a user equipment, wherein transmitting the precoded demodulation reference signal sequence utilizes the code multiplexed resource element.
