摘要：
In some implementations, a method of wireless communication includes obtaining, at a user equipment (UE), an allocation of frequency resources for a group common demodulation reference signal (GC-DMRS) associated with a plurality of UEs that include the UE. The method also includes receiving, at the UE from a base station, a frequency domain resource allocation (FDRA) for a physical downlink shared channel (PDSCH) scheduled for transmission to the UE. The method includes receiving, from the base station, the GC-DMRS and the PDSCH. The method also includes generating a channel estimate based on the GC-DMRS and the allocation of frequency resources to the GC-DMRS. The method further includes demodulating the PDSCH based on the channel estimate. Other aspects and features are also claimed and described.
