Abstract

Claims (34)

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

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 for the downlink pre-emption indication based on the configuration information on the control resource set (CORESET); and

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

wherein respective bits of the bitmap are mapped with different resources to distinguish between resources and to 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,

wherein a time section of the reference downlink resources comprises 14K symbols before a first symbol constituting the control resource set (CORESET) when a monitoring period for the control resource set (CORESET) is K, and

wherein M and N have values such that M=14 and N=1 or M=7 and N=2.

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 the information for setting a unit of time-section resources and a unit of frequency-section resources is received from the base station through higher layer signalling.

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

5 . The method of claim 1 , wherein the bitmap comprises 14 bits.

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

configuring monitoring configuration information for downlink pre-emption indication information;

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 reference downlink resources, and

wherein respective bits of the bitmap are mapped to different resources to distinguish between the resources and to 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,

wherein a time section of the reference downlink resources comprises 14K symbols just before a first symbol constituting the control resource set (CORESET) when a monitoring period for the control resource set (CORESET) is K, and

wherein M and N have values such that M=14 and N=1 or M=7 and N=2.

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

8 . The method of claim 6 , wherein the information for setting a unit of time-section resources and a unit of frequency-section resources is transmitted to the user equipment through higher layer signalling.

9 . The method of claim 6 , wherein a frequency section of the reference downlink resources comprises physical resource blocks constituting an active bandwidth part.

10 . The method of claim 6 , wherein the bitmap comprises 14 bits.

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

a receiver configured to receive monitoring configuration information for downlink pre-emption indication information from a base station, and configured to 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 reference downlink resources for downlink pre-emption indication based on the configuration information on the control resource set (CORESET), and configured to monitor the downlink pre-emption indication information for the 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 reference downlink resources, and

wherein respective bits of the bitmap are mapped to different resources to distinguish between the resources and to 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;

wherein a time section of the reference downlink resources comprises 14K symbols just before a first symbol constituting the control resource set (CORESET) when a monitoring period for the control resource set (CORESET) is K, and

wherein M and N have values such that M=14 and N=1 or M=7 and N=2.

12 . The user equipment of claim 11 , wherein the downlink pre-emption indication information is indicated through group-common downlink control information (DCI).

13 . The user equipment of claim 11 , wherein the information for setting a unit of time-section resources and a unit of frequency-section resources is received from the base station through higher layer signalling.
