Description

CROSS-REFERENCES TO RELATED APPLICATIONS The present application claims priority to Chinese patent application No. 202310834506.1 filed on July 7, 2023, entitled "Measurement Reporting Method, Terminal, Network Device, Apparatus, and Storage Medium", which is hereby incorporated by reference in its entirety. FIELD The present application relates to the field of communication, and in particular to a measurement reporting method, terminal, network device, apparatus, and storage medium. BACKGROUND In related art, the network side configures at most 2 measurement resource groups, corresponding to 2 transmission reception points (TRPs) for a terminal (e.g., user equipment, UE) to perform measurement reporting. TRPs are also called coordination points. When the UE performs measurement reporting, it selects resource pairs/beam pairs from 2 measurement resource groups for reporting. However, in the development of user-centric mobile communication systems, network deployment will be more intensive, that is, TRP deployment will be more intensive. When there are a large number of potential service TRPs, measuring and reporting only 2 TRPs at a time will greatly increase system latency.
