Abstract: Methods, apparatuses, and computer-readable storage media are provided. An example method includes determining R demodulation reference signal (DMRS) ports for a transmission. R is greater than or equal to 2. The method includes determining N sets of one or more time-frequency domain resources for the transmission. N is greater than or equal to 1. The method includes determining RxN resource units on the R DMRS ports and the N sets of one or more time-frequency domain resources. RxN is greater than or equal to 3. The method includes mapping S complex-valued modulation symbols to the RxN resource units. The mapping is based on certain properties. The method includes transmitting, to an apparatus, the S complex-valued modulation symbols over the RxN resource units on the N sets of time-frequency domain resources based on the mapping and using the R DMRS ports.
