Abstract: Provided in embodiments of the present invention are a method and device for feeding back channel information, the method comprising: determining a set of channel measurement resources, the set of channel measurement resources comprising M channel measurement resources, where M is a positive integer; performing channel measurement on the M channel measurement resources; selecting N channel measurement resources from M channel measurement resources according to the channel measurement result, where N is a positive integer, and N≤M; feeding back indication information of the selected N channel measurement resources. The embodiments of the present invention may solve the problem in the related art that a technology for selection of channel measurement resources is incapable of effectively corresponding to multiple paths, leading to low system robustness and transmission efficiency. Thus, when selecting channel measurement resources, it is possible to correspond to multiple paths, thus improving the system robustness and transmission efficiency.

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.
