Method of monitoring control channel in wireless communication system
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.
1. A method of monitoring a control channel in a wireless communication system, the method comprising:
receiving, by a user equipment (UE) from a network, information associated with a discontinuous reception (DRX) period, wherein the DRX period includes a monitored duration and an unmonitored duration; and
monitoring, by the UE, a downlink control channel during the monitored duration, wherein the downlink control channel is a physical channel and is used for a downlink shared channel (DL-SCH),
wherein the UE continues to monitor the downlink control channel while a timer set for discontinuous reception (DRX) is running when the downlink control channel is successfully decoded by the UE during the monitored duration.
2. The method of claim 1 , wherein the downlink control channel comprises scheduling information of a resource allocation.
3. The method of claim 1 , wherein the information indicates to the UE when to stop monitoring the downlink control channel.
4. The method of claim 1 , further comprising transmitting, by the UE, at least one periodic channel quality indicator (CQI) report during the monitored duration.
5. A method of monitoring a control channel in a wireless communication system, the method comprising:
receiving, by a user equipment (UE) from a network, information associated with a discontinuous reception (DRX) period, wherein the DRX period includes a monitored duration and an unmonitored duration; and
monitoring, by the UE, a downlink control channel during the monitored duration, wherein the downlink control channel is a physical channel and is used for a downlink shared channel (DL-SCH),
wherein the UE does not monitor the downlink control channel until a next DRX period when the downlink control channel is not successfully decoded by the UE during the monitored duration.
6. The method of claim 5 , wherein the downlink control channel comprises scheduling information of a resource allocation.
7. The method of claim 5 , wherein the information indicates to the UE when to stop monitoring the downlink control channel.
8. The method of claim 5 , further comprising transmitting, by the UE, at least one periodic channel quality indicator (CQI) report during the monitored duration.
9. A user equipment (UE) for monitoring a control channel in a wireless communication system, the UE comprising:
a processor configured for:
receiving, from a network, information associated with a discontinuous reception (DRX) period, wherein the DRX period includes a monitored duration and an unmonitored duration; and
monitoring a downlink control channel during the monitored duration, wherein the downlink control channel is a physical channel and is used for a downlink shared channel (DL-SCH),
wherein the UE continues to monitor the downlink control channel while a timer set for discontinuous reception (DRX) is running when the downlink control channel is successfully decoded by the UE during the monitored duration.
10. A user equipment (UE) for monitoring a control channel in a wireless communication system, the UE comprising:
a processor configured for:
receiving, from a network, information associated with a discontinuous reception (DRX) period, wherein the DRX period includes a monitored duration and an unmonitored duration; and
monitoring a downlink control channel during the monitored duration, wherein the downlink control channel is a physical channel and is used for a downlink shared channel (DL-SCH),
wherein the UE does not monitor the downlink control channel until a next DRX period when the downlink control channel is not successfully decoded by the UE during the monitored duration.
