Abstract: In one configuration, multiple TRPs, or base stations such a next generation node B (gNB) base stations send different transport blocks (TBs) to a user equipment (UE) at the same time or at different times. In another configuration, multiple base stations may send the same data at the same time to a UE. When the same data is being sent by multiple base stations to a UE, the UE must be notified by some mechanism. Disclosed herein are multiple mechanism for notifying the UE that multiple base stations will be transmitting toe same data at the same time. When there is a backhaul between a TRP and another, each TRP can choose to send the same data stream to increase the reliability of the transmission when, for example, the UE receives at a low signal-to-noise ratio (SNR).

Abstract: A transmitting and receiving point (TRP) divides data scheduled by one downlink control information (DCI) into N data parts, and transmits the N data parts to a receiving side, where N≥1. A value of N and whether the N data parts have a correlation in a case of N>1 are determined by at least one of following scheduling information: a transmission configuration indicator (TCI) field, a demodulation reference signal (DMRS) port indicator, a modulation and coding scheme (MCS), a redundancy version (RV) or a new data indicator (NDI). After receiving the N data parts sent by the TRP, the receiving side determines whether the N data parts have the correlation according to at least one of the TCI, the DMRS port indicator, the MCS, the RV, or the NDI.
