Abstract
In some embodiments, an apparatus of a Fifth Generation (5G) NodeB (gNB) comprises one or more baseband processors to encode one or more channel state information reference signals (CSI-RS) to be transmitted to a user equipment (UE). The one or more CSI-RS signals comprise a complex sequence mapped to a resource element (RE) such that all CSI-RS ports use an identical sequence for the one or more CSI-RS signals in a symbol. In other embodiments, the gNB comprises one or more baseband processors to encode a scrambling identity (ID) configuration for one or more demodulation reference signals (DMRS), wherein the scrambling ID configuration indicates one of two scrambling IDs to be signaled to a UE.
