Abstract:
A user equipment (UE) is configured with multi-transmission and reception point (multi-TRP) operation. The UE groups capabilities of handling two overlapping physical downlink shared channel (PDSCH) transmissions into a plurality of groups, determining a UE capability of handling two overlapping PDSCH transmissions based on the plurality of groups and transmits the UE capability to a next generation nodeB (gNB) of a 5G new radio (NR) wireless network. The UE also determines if a demodulation reference signal (DMRS) of a physical downlink shared channel (PDSCH) transmission collides with a cell-specific reference signal (CRS) of a long term evolution (LTE) transmission and determines if the CRS originated from a same multi-transmission/reception point (TRP) as the DMRS.
