Description

Method and device for paging message transmission

Technical field

Background technique

In the fifth-generation mobile communication technology (5G, 5th Generation) system, low energy consumption and low latency are important technical indicators, and the end-to-end delay needs to reach the level of 5 milliseconds (ms). Currently, the discontinuous reception (DRX) of the UE (User Equipment) in the LTE (Long Term Evolution) system is transmitted through the PDSCH (Physical Downlink Shared Channel). In the paging message, the UE activates a PDCCH (Physical Downlink Control Channel) and a PDSCH (Physical Downlink Shared Channel) at a PO (Paging Occasion) of a designated PF (Paging Frame). Monitoring of the physical downlink shared channel). For a UE, the interval between every two PFs is the paging cycle. The length of the Paging Cycle is at least 32 radio frames, that is, 320 ms.
