Method and device for transmitting uplink data
Provided are a method and a device for transmitting uplink data according to uplink cancellation indication information in a next-generation wireless network. A method of a terminal for transmitting uplink data may include: transmitting uplink data on the basis of uplink data resource allocation information; monitoring uplink cancellation indication information on the basis of monitoring configuration information on the uplink cancellation indication information; receiving the uplink cancellation indication information; and suspending the transmission of on-going uplink data on the basis of the uplink cancellation indication information.
1. A method of a user equipment (UE) for receiving uplink (UL) indication, the method comprising:
receiving, through a higher layer signaling, configuration information for monitoring the UL indication; and
receiving the UL indication based on the configuration information,
wherein a transmission of UL data is not performed based on the received UL indication,
wherein the configuration information comprises radio network temporary identifier (RNTI) information for monitoring the UL indication, and
wherein the RNTI information is associated with at least one of control resource set (CORESET) and search space configuration information, or period configuration information, for monitoring for the UL indication.
2. The method according to claim 1 , wherein the UL indication is indicated through UE-group common downlink control information (DCI).
3. The method according to claim 1 , wherein the transmission of the UL data is not performed after a certain time duration has elapsed based on receiving the UL indication.
4. The method according to claim 1 , further comprising:
transmitting the UL data based on UL data resource allocation information,
wherein the transmission of the UL data is not performed within a slot that receives the UL indication or for all of a plurality of slots allocated based on the UL data resource allocation information.
5. The method according to claim 1 , wherein the UL indication includes information on a suspending duration for suspending the transmission of the UL data, and
wherein the suspending of the transmission of the UL data is performed during the suspending duration, and the transmission of the UL data is resumed after the suspending duration has elapsed.
6. A method of a base station for transmitting uplink (UL) indication to a user equipment (UE), the method comprising:
transmitting, through a higher layer signaling, configuration information for monitoring the UL indication to the UE; and
transmitting the UL indication based on the configuration information,
wherein the UL indication is used to prevent a transmission of UL data by the UE,
wherein the configuration information comprises radio network temporary identifier (RNTI) information for monitoring the UL indication by the UE, and
wherein the RNTI information is associated with at least one of control resource set (CORESET) and search space configuration information, or period configuration information, for monitoring for the UL indication.
7. The method according to claim 6 , wherein the UL indication is indicated through UE-group common downlink control information (DCI).
8. The method according to claim 6 , wherein the transmission of the UL data is not performed by the UE after a certain time duration has elapsed based on receiving the UL indication by the UE.
9. The method according to claim 6 , further comprising:
receiving the UL data based on UL data resource allocation information,
wherein the transmission of the UL data is not performed by the UE within a slot over which the UL indication has been received or for all of a plurality of slots allocated based on the UL data resource allocation information.
10. The method according to claim 6 , wherein the UL indication includes information on a suspending duration for suspending the transmission of the UL data, and
wherein the transmission of the UL data is not performed by the UE during the suspending duration, and the transmission of the UL data is resumed after the suspending duration has elapsed.
11. A user equipment (UE) for receiving uplink (UL) indication, the UE comprising:
a receiver configured to receive, through a higher layer signaling, configuration information for monitoring the UL indication, and receive the UL indication based on the configuration information; and
a controller configured to prevent a transmission of UL data based on the received UL indication,
wherein the configuration information comprises radio network temporary identifier (RNTI) information for monitoring the UL indication, and
wherein the RNTI information is associated with at least one of control resource set (CORESET) and search space configuration information, or period configuration information, for monitoring for the UL indication.
12. The UE according to claim 11 , wherein the UL indication is indicated through UE-group common downlink control information (DCI).
13. The UE according to claim 11 , wherein the transmission of the UL data is not performed after a certain time duration has elapsed based on receiving the UL indication.
14. The UE according to claim 11 , further comprising:
a transmitter configured to transmit the UL data based on UL data resource allocation information,
wherein the transmission of the UL data is not performed within a slot that receives the UL indication or for all of a plurality of slots allocated based on the UL data resource allocation information.
15. The UE according to claim 11 , wherein the UL indication includes information on a suspending duration for suspending the transmission of the UL data, and
wherein the controller suspends the transmission of the UL data during the suspending duration, and resumes the transmission of the UL data after the suspending duration has elapsed.
