1. A processor of a user equipment (UE) configured to:
establish a connection to a fifth generation (5G) new radio (NR) network, wherein the connection is configured to utilize cyclic prefix (CP)—orthogonal frequency division multiplexing (OFDM) waveform and demodulation reference signal (DMRS) type 1;
receive a DMRS port indication configured to indicate one or more DMRS ports assigned to the UE, wherein single symbol DMRS type 1 is configured to support up to 8 DMRS ports and two symbol DMRS type 1 is configured to support up to 16 DMRS ports;
receive a bitmap for a physical downlink shared channel (PDSCH), wherein a first resource block group (RBG) and a last RBG indicated in the bitmap contain an even number of physical resource blocks (PRBs); and
perform a transmission operation or a reception operation using the one or more DMRS ports assigned to the UE.
