US 12,113,740 B2 · Communication method and communications apparatus

Abstract

Example communication methods and communications apparatus are described. One example method include: receiving downlink control information (DCI), where the DCI indicates N demodulation reference signal (DMRS) ports. The N DMRS ports correspond to each of M physical downlink shared channel (PDSCH) transmission units, at least two of the M PDSCH transmission units correspond to different transmission configuration indicator (TCI)-states, N is an integer greater than or equal to 1, and M are integers greater than or equal to 2. M PDSCHs are received based on the DCI.
