Title:
REFERENCE SIGNAL DETERMINATION METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/197470
Kind Code:
A1
Abstract:
Provided are a reference signal determination method and apparatus, an electronic device and a storage medium. The method comprises: detecting a downlink signal or monitoring a physical downlink control channel (PDCCH) to obtain a first result, wherein the first result is a detection result or a monitoring result; and according to the first result, determine whether a reference signal is valid. Whether a reference signal is valid is determined by means of the structure of detecting a downlink signal or monitoring a PDCCH, thereby optimizing system overheads. In addition, a UE only needs to wake up before the last synchronization signal block before a PO or a synchronization signal block burst, and the UE achieves AGC adjustment and channel tracking (or AGC adjustment, and channel tracking and measurement) by means of the last synchronization signal block (or the synchronization signal block burst) and a reference signal; alternatively, the UE only uses the reference signal to perform AGC adjustment, and channel tracking and measurement, thereby effectively shortening the time for the UE to wake up in advance, and achieving energy conservation of the UE.
