MIXED DISCONTINUOUS RECEPTION METHOD, BASE STATION AND USER DEVICE

摘要

A mixed discontinuous reception DRX method, a base station and a user device are provided. The mixed DRX method includes the following steps: an extended discontinuous reception DRX cycle mode is configured, and in the extended DRX cycle mode, each extended DRX period is larger than or equal to a time alignment timer TAT of a user device; a time alignment update TAU DRX period mode is configured, and a first TAU DRX is configured at the first predetermined time less than TAT that at the first DRX period starting or after it starting, wherein the time difference between any two adjacent TAU DRX periods of multiple TAU DRX periods is less than TAT; the extended DRX cycle mode and the TAU DRX period mode are sent to the user device; a time alignment TA command is sent at the second predetermined time which after a sounding reference signal SRS sent by the user device is received. The above mixed DRX method, base station and user device can have DRX cycle corresponding to the periodicity service characteristic of the user device, and can make the user device always maintain uplink synchronization at the same time.
