Abstract
A method of monitoring a control channel in a wireless communication system includes monitoring a physical down-link control channel (PDCCH) during a monitored duration, wherein the monitored duration is a part of a discontinuous reception (DRX) period, the DRX period specifying the periodic repetition of the monitored duration followed by a non-monitored duration. By monitoring a control channel during a DRX period, battery consumption of a user equipment can be reduced and an operation time of the user equipment can be increased.
Claims10
A method of monitoring a control channel in a wireless communication system, the method comprising:
- receiving information associated with a discontinuous reception (DRX) period, wherein the DRX period includes a monitored duration and an unmonitored duration;
- monitoring a downlink control channel during the monitored duration;
- determining whether the downlink control channel is successfully decoded by a user equipment (UE) during the monitored duration;
- if the downlink control channel is successfully decoded by the UE during the monitored duration, continuing monitoring the downlink control channel while a timer set for an extended duration is running;
- and
- entering a DRX mode after the timer expires.
A user equipment (UE) in a wireless communication system, comprising:
- a receiver;
- and
- a processor coupled to the receiver and configured to:
- receive information associated with a discontinuous reception (DRX) period, wherein the DRX period includes a monitored duration and an unmonitored duration;
- monitor a downlink control channel during the monitored duration;
- determine whether the downlink control channel is successfully decoded by the UE during the monitored duration;
- if the downlink control channel is successfully decoded by the UE during the monitored duration, continue monitoring the downlink control channel while a timer set for an extended duration is running;
- and
- enter a DRX mode after the timer expires.
