Method and apparatus for transmitting and receiving data in wireless communication system
The present disclosure relates to a method and apparatus for transmitting and receiving data in a wireless communication system. An operating method of a terminal in a wireless communication system may include receiving configuration information related to discontinuous reception (DRX) through radio resource control (RRC) signaling from a base station, wherein the configuration information related to the DRX includes information related to a cycle of the DRX and information related to a timer of a duration for monitoring a physical downlink control channel (PDCCH) within the cycle of the DRX, receiving configuration information about downlink control information (DCI) related to an indication of wake up in the DRX, through RRC signaling from the base station, identifying the wake up in the DRX based on the DCI, and when the wake up is not identified in the DRX, performing periodic channel state information (CSI) reporting, based on whether information indicating the periodic CSI reporting is included in the configuration information about the DCI.
1. An operating method of a terminal in a wireless communication system, the operating method comprising:
receiving, from a base station, a radio resource control (RRC) reconfiguration message including information related to a discontinuous reception (DRX)-onDurationTimer and information indicating a periodic channel status information (CSI) reporting;
receiving, from the base station, downlink control information (DCI) including wake-up information indicating a first value or a second value; and
in case that the wake-up information indicates the first value, not starting the DRX-onDurationTimer and performing the periodic CSI reporting based on the information indicating the periodic CSI reporting.
2. The operating method of claim 1 , further comprising:
in case that the wake-up information indicates the first value and the information indicating the periodic CSI reporting is not included in the RRC reconfiguration message, not starting the DRX-onDurationTimer and not performing the periodic CSI reporting.
3. The operating method of claim 1 , further comprising:
in case that the wake-up information indicates the second value, starting the DRX-onDurationTimer and performing the periodic CSI reporting based on the information indicating the periodic CSI reporting.
4. The operating method of claim 1 , wherein the RRC reconfiguration message further comprises offset information between a time at which a search time of the DCI starts and a time at which the DRX-onDurationTimer starts.
5. The operating method of claim 1 , wherein in case that the wake-up information indicates the second value, the operating method further comprises:
performing physical downlink control channel (PDCCH) monitoring during a duration indicated by the information related to the DRX-onDurationTimer, by starting the DRX-onDurationTimer.
6. The operating method of claim 1 ,
wherein the wake-up information is a wake-up signal (WUS), and
wherein the first value indicates WUS OFF, and the second value indicates WUS ON.
7. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
at least one processor configured to:
receive, from a base station, a radio resource control (RRC) reconfiguration message including information related to a discontinuous reception (DRX)-onDurationTimer and information indicating a periodic channel status information (CSI) reporting,
receive, from the base station, downlink control information (DCI) including wake-up information indicating a first value or a second value, and
in case that the wake-up information indicates the first value, not starting the DRX-onDuration Timer and perform the periodic CSI reporting based on the information indicating the periodic CSI reporting.
8. The terminal of claim 7 , wherein the at least one processor is further configured to:
not start the DRX-onDuration Timer and not perform the periodic CSI reporting, in case that the wake-up information indicates the first value and the information indicating the periodic CSI reporting is not included in the RRC reconfiguration message.
9. The terminal of claim 7 , wherein the at least one processor is further configured to:
start the DRX-onDurationTimer and perform the periodic CSI reporting based on the information indicating the periodic CSI reporting in case that the wake-up information indicates the second value.
10. The terminal of claim 7 , wherein the RRC reconfiguration message further comprises offset information between a time at which a search time of the DCI starts and a time at which the DRX-onDurationTimer starts.
11. The terminal of claim 7 , wherein the at least one processor is further configured to:
in case that the wake-up information indicates the second value, perform physical downlink control channel (PDCCH) monitoring during a duration indicated by the information related to the DRX-onDurationTimer, by starting the DRX-onDurationTimer.
12. The terminal of claim 7 ,
wherein the wake-up information is a wake-up signal (WUS), and
wherein the first value indicates WUS OFF, and the second value, indicates WUS ON.
13. A non-transitory computer-readable recording medium having stored therein a program for performing a method comprising:
receiving, from a base station, a radio resource control (RRC) reconfiguration message including information related to a discontinuous reception (DRX)-onDurationTimer and information indicating a periodic channel status information (CSI) reporting;
receiving, from the base station, downlink control information (DCI) including wake-up information indicating a first value or a second value; and
in case that the wake-up information indicates the first value, not starting the DRX-onDurationTimer and performing the periodic CSI reporting based on the information indicating the periodic CSI reporting.
