Method and system for recovering from DRX timing de-synchronization in LTE — ACTIVE
First Claim
Patent Images
1. A method for Discontinuous Reception (DRX) operation, comprising:
- while a user equipment (‘
UE’
) is in an active mode, waking up a receiver of the UE at a wake up time, the wake up time corresponding to a radio frame number equal to a radio frame offset plus N times a DRX interval, wherein N is an integer greater than or equal to zero;
wherein the UE checks whether data addressed for the UE is available from a network element at the wake up time.

Abstract
A method for recovering from discontinuous reception (DRX) timing de-synchronization between the UE and the eNB in an LTE_ACTIVE state having the steps of: the eNB detecting DRX timing de-synchronization; transmitting an indicator to a User Equipment (UE) to resume continuous reception; and waiting for an indication from the UE of whether a Continuous Reception Response or Continuous Reception Notification was received.

11. A user equipment configured for discontinuous reception operation comprising:
-
a communications subsystem having a receiver; and a processor; wherein the user equipment is configured to, “
while in active mode,”
wake up the receiver at a wake up time, the wake up time corresponding to a radio frame number equal to a radio frame offset plus N times a DRX interval, where N is an integer greater than or equal to zero; andwherein the user equipment is further configured to check whether data addressed for the user equipment is available from a network element at the wake up time. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
