Abstract
This disclosure provides systems, methods and apparatuses for transmissions with non-transparent precoder cycling. A network node generates a precoding matrix including a number of sub-matrices equal to a number of antenna groups. A first sub-matrix for a first antenna group is the same for each frequency domain resource unit of a frequency domain resource group. A phase of each subsequent sub-matrix for each subsequent antenna group is shifted to be orthogonal for each frequency domain resource unit. The network node applies the precoding matrix to both a data signal and a demodulation reference signal (DMRS) of a transmission for each frequency domain resource unit of the frequency domain resource group and transmits the precoded transmission via the antenna groups. A UE receives the transmission having non-transparent precoder cycling, estimates a channel of the transmission based on the precoding matrix, and demodulates the data signal based on the estimated channel.
