Abstract

Embodiments include methods, performed by a user equipment (UE), for transmitting or receiving a plurality of physical data channels in a wireless network. Such methods include receiving, from the wireless network, an indication of a Transmission Configuration Indicator (TCI) state that includes one or more source reference signal (RS) pairs. Each source RS pair has a pair of quasi-colocation (QCL) relations with antenna ports, for demodulation reference signals (DM-RS), that are mapped to a plurality of code-division multiplexing (CDM) groups. Such methods include receiving/transmitting the physical data channels based on the QCL relations for the source RS pairs of the indicated TCI state. Each physical data channel corresponds to a CDM group and is received/transmitted in association with the DM-RS having antenna ports mapped to the corresponding CDM group. Other embodiments include complementary methods performed by a wireless network, and UEs and wireless networks configured to perform such methods.
