Problems solved by technology

[0005] However, in the prior art, the UE may need to wake up before the last two synchronization signal blocks before the PO, which will cause the UE to wake up too early and consume more power. In this case, it can be reduced by adding additional reference signals Time for UE to wake up early
However, introducing additional reference signals may increase system overhead

Abstract

The invention provides a reference signal determination method, a reference signal determination device, electronic equipment and a storage medium. The reference signal determination method comprisesthe steps of: acquiring configuration information; and determining whether a reference signal is valid according to the configuration information. The reference signal determination method determineswhether the reference signal is valid or not through using the configuration information, so that the system overhead is optimized. Besides, the UE only needs to wake up in front of the last synchronization signal block in front of the PO, realizes AGC adjustment, channel tracking and measurement through using the last synchronization signal block and the reference signal, and effectively shortensthe early wake-up time of the UE.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 2020100236433 and the application title "reference signal determination method, device, electronic equipment and storage medium" submitted to the China Patent Office on January 09, 2020, the entire content of which is incorporated by reference incorporated in this application. technical field [0002] The present application relates to the technical field of communications, and in particular to a reference signal determination method, device, electronic equipment, and storage medium. Background technique [0003] When the user equipment (User Equipment, UE) is in the idle state (Idle mode, RRC IDLE), the UE needs to monitor the paging physical downlink control channel (Physical Downlink Control Channel, PDCCH) used to carry the paging message, to determine whether A paging message is sent to itself. At present, the UE performs automatic gain control (Automatic Gain Cont...
