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.

Abstract: Methods and devices for channel state reporting in wireless communications are disclosed. In one example aspect, a method for wireless communication includes determining, by a user device, a first reference signal received power (RSRP) value. The first RSRP value is a maximum measured value of a RSRP group. The method also includes determining, by the user device, a second RSRP value based a differential of the first RSRP value and reporting the first RSRP value and the second RSRP value to a base station.
