Abstract
There is provided a method for enabling a user equipment (UE) to transition between a non-discontinuous reception (Non-DRX) level and at least one discontinuous reception (DRX) level. The UE in a DRX level wakes up periodically to monitor a scheduling channel. The method includes receiving a DRX indicator in a Non-DRX level with continuously monitoring the scheduling channel and transitioning from the Non-DRX level to a DRX level indicated by the DRX indicator. The UE can transition between multiple DRX levels by an explicit command/signaling.
Claims10
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 the scheduling channel;
- starting or restarting a first timer when the scheduling channel indicates a transmission or reception of data;
- receiving a discontinuous reception (DRX) indicator from a base station while the first timer is running, wherein the DRX indicator indicates a long DRX level or a short DRX level;
- if the DRX indicator indicates a short DRX level, transitioning to the short DRX level and, thereafter, transitioning from the short DRX level to the long DRX level when a predefined time period elapses after the transition to the short DRX level;
- and
- if the DRX indicator indicates a long DRX level, transitioning to the long DRX level.
User equipment (UE) comprising:
- a memory;
- and
- a processor operably coupled with the memory and configured to:
- monitor a scheduling channel;
- start or restart a first timer when the scheduling channel indicates a transmission or reception of data;
- receive a discontinuous reception (DRX) indicator from a base station while the first timer is running, the DRX indicator indicates a long DRX level or a short DRX level;
- if the DRX indicator indicates a short DRX level, transitioning to the short DRX level and, thereafter, transitioning from the short DRX level to the long DRX level when a predefined time period elapses after the transition to the short DRX level;
- and
- if the DRX indicator indicates a long DRX level, transitioning to the long DRX level.
