Abstract

Disclosed are UE-feedback techniques to support the adaptive DMRS transmission. A UE and eNB support adaptive DMRS transmission in which an eNB adjusts (i.e., selects) a DMRS pattern based on information describing channel conditions perceived by the UE. The UE may explicitly provide the channel conditions, or implicitly provide them by selecting a desired DMRS pattern.
