Abstract:
1. A method of transitioning a reception level to monitor a scheduling channel in a wireless communication system, carried in a user equipment (UE), comprising: monitoring continuously a scheduling channel while operating at a non-discontinuous reception (Non-DRX) level while a first timer is running, wherein a first timer starts when the scheduling channel indicates a transmission or reception of data by a base station; when a message comprising a DRX indicator is received from a base station while the first timer is running and the DRX indicator indicates a DRX level transition, transitioning to a first DRX level with a first DRX period and starting a second timer; monitoring discontinuously the scheduling channel in the first DRX level; and when the second timer expires, transitioning to a second DRX level with a second DRX period, wherein the first DRX period is shorter than the second DRX period.
