Patent ID: 11071098

Abstract:
Techniques are described herein for jointly configuring one or more parameters of a plurality of demodulation reference signals (DMRSs) across one or more data channels. A DMRS may be used to estimate one or more channel parameters for a plurality of data channels. To share a DMRS between multiple data channels it may be beneficial to jointly configure one or more parameters of the DMRSs associated with the data channel. A user equipment (UE) may be configured to determine one or more parameters of a plurality of DMRSs using a DMRS pattern configuration that indicates associations between parameters of the different DMRSs. The UE may select a configuration from the one or more configurations of the DMRS pattern configuration based on a variety of factors. For example, the UE may select a joint DMRS configuration based on whether DMRS sharing is enabled or DMRS bundling is enabled.
