Abstract: A wireless communication method is described for receiving a reporting configuration associated with one or more reporting criteria. The received reporting configuration is also linked to one or more channel state information (CSI) resource settings that provide a configuration information. Each CSI resource setting identifies one or more resource sets, and each resource set includes one or more reference signal resources. Based on one or more reporting criteria, a user equipment can generate a report that can be transmitted to a base station.

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.

Abstract: A method and apparatus for information reporting as well as a method and apparatus for information transmission are provided. The method for information reporting includes: receiving, by a second communication node, a reference signal from a first communication node, to determine a reference signal-related index and/or channel state information; reporting, by the second communication node, a set to the first communication node, and the set includes at least one of: the reference signal-related index and the channel state information. This technical solution solves the problems of low flexibility and poor adaptability of beam-related information reporting in the related art; the second communication node reports its own capability, so that the first communication node can indicate a beam reporting that meets to user capability, thereby improving the stability of beam-related information reporting.
