Abstract
Methods, systems, and devices for wireless communications are described to enable a user equipment (UE) to bundle reference signals, such as demodulation reference signals (DMRSs), by maintaining one or more coherence properties across DMRSs. A base station may transmit an indication of a DMRS bundling configuration to the UE, and the UE may transmit a DMRS bundling capability indication to the base station. The base station may transmit DCI to the UE, and the UE may determine whether to maintain or alter DMRS bundling (for example, maintain or alter one or more coherence properties) for one or more physical shared channels based on the DCI. The UE may maintain or alter one or more coherence properties of the one or more physical shared channels based on determining whether to maintain DMRS bundling and may transmit the one or more physical shared channels and associated DMRSs to the base station.
