Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may measure a frequency selectivity of a channel between the UE and a base station and may transmit signaling to the base station indicating one or both of a frequency selectivity metric or a recommended demodulation reference signal (DMRS) port multiplexing pattern based on measuring the frequency selectivity. In some aspects, the UE may transmit the signaling to assist the base station in configuring a DMRS port multiplexing pattern based on current channel conditions. For example, if the frequency selectivity metric satisfies a threshold, the UE may recommend a DMRS port multiplexing pattern absent of code division multiplexing (CDM). Alternatively, if the frequency selectivity metric fails to satisfy the threshold, the UE may recommend a DMRS port multiplexing patter including CDM.
