Abstract

The invention provides a power saving method for user equipment in an idle mode and a device. The method comprises steps: an expanded DRX cycle is configured, wherein the expanded DRX cycle is larger than the conventional DRX cycle and larger than the SFN cycle; and the expanded DRX cycle is sent to the UE so as to enable the UE to use the expanded DRX cycle to listen to a paging message in the idle mode.

Description

technical field [0001] The present invention relates generally to the field of wireless communications, and more particularly to methods and apparatus for power saving of idle mode user equipment (UE). Background technique [0002] It is known that for idle mode UEs, using discontinuous reception (DRX) mechanism to monitor paging messages and save power is a common method. When the UE is in the RRC_IDLE state, the UE can monitor only a paging message in a specific subframe using DRX. Specifically, the UE can calculate the paging frame (PF) number and the paging opportunity (PO) subframe in the paging frame by using the system configuration parameters and the UE's International Mobile Subscriber Identity (IMSI) according to the DRX cycle No. Therefore, in DRX paging, the UE only needs to receive the physical downlink control channel (PDCCH) once at a specific paging time in each DRX cycle, and at other times, it can go to sleep state to save power. [0003] When in RRC_IDL...
