Abstract

Provided are a method for monitoring, transmitting, and receiving downlink pre-emption indication information in a next-generation/5G radio access network. The method may include receiving monitoring configuration information for downlink pre-emption indication information from a base station; receiving configuration information on a control resource set (CORESET) for receiving the downlink pre-emption indication information from the base station; configuring reference downlink resources based on the configuration information on a control resource set; and monitoring the downlink pre-emption indication information for the reference downlink resources.

Claims (33)

1. A method for receiving downlink pre-emption indication information by a user equipment, the method comprising:

receiving configuration information for monitoring downlink pre-emption indication information through higher-layer signalling from a base station;

receiving configuration information on a control resource set (CORESET) for receiving the downlink pre-emption indication information from the base station;

configuring downlink resources for the downlink pre-emption indication based on the configuration information on a CORESET; and

monitoring the downlink pre-emption indication information for the downlink resources,

wherein the downlink pre-emption indication information comprises a bitmap indicating information on at least one of time-section resources and frequency-section resources in which pre-emption has occurred, among the downlink resources,

wherein respective bits of the bitmap indicate one of M different time-section resources and indicate one of N different frequency-section resources, where M and N is an integer number equal to or greater than 1,

wherein the configuration information on a control resource set (CORESET) includes a monitoring period K for the CORESET where K is an integer number equal to or greater than 1, and

wherein a time section of the reference downlink resources comprises specific symbols related to the monitoring period K just before a first symbol constituting the CORESET.

2. The method of claim 1 , wherein the downlink pre-emption indication information is indicated through group-common downlink control information (DCI).

3. The method of claim 1 , wherein M=14 and N=1 or M=7 and N=2.

4. The method of claim 1 , wherein a frequency section of the downlink resources comprises physical resource blocks constituting an active bandwidth part.

5. A method for transmitting downlink pre-emption indication information by a base station, the method comprising:

configuring configuration information monitoring for downlink pre-emption indication information through higher-layer signalling;

transmitting, to a user equipment, configuration information on a control resource set (CORESET) for transmitting the downlink pre-emption indication information; and

transmitting, to the user equipment, the downlink pre-emption indication information for reference downlink resources,

wherein the downlink pre-emption indication information comprises a bitmap indicating information on at least one of time-section resources and frequency-section resources in which pre-emption has occurred, among the downlink resources,

wherein respective bits of the bitmap indicate one of M different time-section resources and indicate one of N different frequency-section resources, where M and N is an integer number equal to or greater than 1,

wherein the configuration information on a control resource set (CORESET) includes a monitoring period K for the CORESET where K is an integer number equal to or greater than 1, and

wherein a time section of the reference downlink resources comprises specific symbols related to the monitoring period K just before a first symbol constituting the CORESET.

6. The method of claim 5 , wherein the downlink pre-emption indication information is transmitted to the user equipment through group-common downlink control information (DCI).

7. The method of claim 5 , wherein M=14 and N=1 or M=7 and N=2.

8. The method of claim 5 , wherein a frequency section of the downlink resources comprises physical resource blocks constituting an active bandwidth part.

9. A user equipment for receiving downlink pre-emption indication information, the user equipment comprising:

a receiver configured to receive configuration information for monitoring downlink pre-emption indication information through higher-layer signalling and receive configuration information on a control resource set (CORESET) for receiving the downlink pre-emption indication information from the base station; and

a controller configured to configure downlink resources for the downlink pre-emption indication based on the configuration information on a CORESET, and configured to monitor the downlink pre-emption indication information for the downlink resources,

wherein the downlink pre-emption indication information comprises a bitmap indicating information on at least one of time-section resources and frequency-section resources in which pre-emption has occurred, among the downlink resources,

wherein respective bits of the bitmap indicate one of M different time-section resources and indicate one of N different frequency-section resources, where M and N is an integer number equal to or greater than 1,

wherein the configuration information on a control resource set (CORESET) includes a monitoring period K for the CORESET where K is an integer number equal to or greater than 1, and

wherein a time section of the reference downlink resources comprises specific symbols related to the monitoring period K just before a first symbol constituting the CORESET.

10. The user equipment of claim 9 , wherein the downlink pre-emption indication information is indicated through group-common downlink control information (DCI).

11. The user equipment of claim 9 , wherein M=14 and N=1 or M=7 and N=2.

12. The user equipment of claim 9 , wherein a frequency section of the downlink resources comprises physical resource blocks constituting an active bandwidth part.
