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.

monitoring, by the wireless device, the downlink pre-emption information based on the RNTI information and the information related to the CORESET;

wherein the downlink pre-emption information indicates at least one of a time resource or a frequency resource in which pre-emption has occurred,

wherein the time resource is configured within a time duration, which is determined based on the information related to the CORESET,

wherein the downlink pre-emption information comprises a plurality of downlink pre-emption indicators,

wherein each of the plurality of downlink pre-emption indicators corresponds to a respective pre-empted region,

wherein the information related to a 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 duration of at least one of the time 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 information related to the CORESET comprises associated period information.

3. The method of claim 1 , wherein the time resource comprises one or more symbols, and the frequency resource comprises one or more physical resource blocks.

4. The method of claim 1 , wherein the downlink pre-emption information is received through a group common downlink control information.

5. The method of claim 4 , wherein the frequency resource comprises at least one different frequency section in which pre-emption has occurred.

6. The method of claim 1 , wherein the time resource comprises at least one different time section in which pre-emption has occurred.

7. A device, comprising:

a transmitter;

a receiver; and

a controller which controls the transmitter and the receiver thereby performing operations including:

receiving, by the wireless device, radio network temporary identifier (RNTI) information for monitoring downlink pre-emption information through a higher layer signaling;

receiving, by the wireless device, information related to a control resource set (CORESET), and

monitoring, by the wireless device, the downlink pre-emption information based on the RNTI information and the information related to the CORESET;

wherein the downlink pre-emption information indicates at least one of a time resource or a frequency resource in which pre-emption has occurred,

wherein the time resource is configured within a time duration, which is determined based on the information related to the CORESET,

wherein the downlink pre-emption information comprises a plurality of downlink pre-emption indicators,

wherein each of the plurality of downlink pre-emption indicators corresponds to a respective pre-empted region,

wherein the information related to a CORSET includes a monitoring period K for the CORESET where K is an integer number equal to or greater than 1, and

wherein a time duration of at least one of the time resources comprises specific symbols related to the monitoring period K just before a first symbol constituting the CORESET.

8. The device of claim 7 , wherein the information related to the CORESET comprises associated period information.

9. The device of claim 7 , wherein the time resource comprises one or more symbols, and the frequency resource comprises one or more physical resource blocks.

10. The device of claim 7 , wherein the downlink pre-emption information is received through a group common downlink control information.

11. The device of claim 7 , wherein the time resource comprises at least one different time section in which pre-emption has occurred.

12. The device of claim 11 , wherein the frequency resource comprises at least one different frequency section in which pre-emption has occurred.

13. A base station, comprising:

a transmitter;

a receiver; and

a controller which controls the transmitter and the receiver thereby performing operations including:

transmitting radio network temporary identifier (RNTI) information for monitoring downlink pre-emption information through a higher layer signaling; and

transmitting information related to a control resource set (CORESET);

wherein the downlink pre-emption information indicates at least one of a time resource and a frequency resource in which pre-emption has occurred,

wherein the time resource is configured within a time duration, which is determined based on the information related to the CORESET,

wherein the downlink pre-emption information comprises a plurality of downlink pre-emption indicators,

wherein each of the plurality of downlink pre-emption indicators corresponds to a respective pre-empted region,

wherein the information related to a CORSET includes a monitoring period K for the CORESET where K is an integer number equal to or greater than 1, and

wherein a time duration of at least one of the time resources comprises specific symbols related to the monitoring period K just before a first symbol constituting the CORESET.

14. The base station of claim 13 , wherein the information related to the CORESET comprises associated period information.

15. The base station of claim 13 , wherein the time resource comprises one or more symbols, and the frequency resource comprises one or more physical resource blocks.

16. The base station of claim 13 , wherein the downlink pre-emption information is received through a group common downlink control information.

17. The base station of claim 13 , wherein the time resource comprises at least one different time section in which pre-emption has occurred.

18. The base station of claim 17 , wherein the frequency resource comprises at least one different frequency section in which pre-emption has occurred.

19. A communication method, comprising:

receiving, by a communication device, a first message comprising a radio network temporary identifier (RNTI) and information related to a control resource set (CORESET) through a higher layer signaling;

obtaining, by the communication device, downlink pre-emption information in a first CORESET based on the RNTI and the information related to a CORESET; and

determining, by the communication device, one or more pre-empted resources based on the downlink pre-emption information,

wherein:

the downlink pre-emption information indicates the one or more pre-empted resources in a time duration prior to a first symbol of the first CORESET; and
