Patent ID: 11432319

Abstract:
A user equipment (UE) may receive a downlink control information (DCI) including an antenna port field and a transmission configuration indication (TCI) field for scheduling a physical downlink shared channel (PDSCH). The TCI field may indicate that two or more reference signals apply to two or more demodulation reference signal (DMRS) ports across all resource blocks and symbols for the PDSCH for at least one transmission layer of the PDSCH. The antenna port field may indicate a plurality of indicated DMRS ports. The UE may map two or more DMRS ports of the indicated DMRS ports to at least one transmission layer of the PDSCH. The UE may receive the at least one transmission layer of the PDSCH as a single-frequency-network (SFN) transmission based on the two or more reference signals and the two or more DMRS ports.
