Abstract

An example communication method in a terminal of a mobile communication system includes receiving, from a base station, first information associated with a resource allocation scheme for a first service and a second service; receiving, from the base station, control information associated with the first service; and receiving, from the base station, data for the first service on the basis of the control information and the first information.

First claim

What is claimed is:

1. A method of operating a base station for communication in a mobile communication system, the method comprising:
transmitting a radio resource control (RRC) message to a user equipment (UE), wherein the RRC message includes information related to preemption for use in configuring the UE to monitor Physical Downlink Control Channel (PDCCH);
transmitting data in a first slot which includes a first PDCCH and a first Physical Downlink Shared Channel (PDSCH), wherein the first PDCCH includes a first downlink control information (DCI) for use in receiving the first PDSCH; and
transmitting data in a second slot includes a second PDCCH including a second DCI having a preemption indicator, the data in the first slot being transmitted prior to the data in the second slot,
wherein the preemption indicator included in the second DCI of the second PDCCH is for use by the UE in identifying that preemption applies to at least part of a resource of the first PDSCH.

2. The method of claim 1 , wherein the information related to preemption includes information corresponding to a resource size in a time domain.

3. The method of claim 1 , wherein the preempted part of the first PDSCH is for use in providing a low-latency or high-reliability communication service, and another part of the first PDSCH is for use in providing high-speed or broadband data communication service.

4. The method of claim 1 , wherein the first DCI includes the unit information for feedback.

5. The method of claim 1 , further comprising:
receiving a feedback, from the UE, wherein the feedback is related to the unit information which is transmitted using the first DCI.

6. A base station for communication in a mobile communication system, the base station comprising:
a transceiver; and
a controller configured to:
transmit a radio resource control (RRC) message to a user equipment (UE), wherein the RRC message includes information related to preemption which is for use in configuring the UE to monitor Physical Downlink Control Channel (PDCCH);
transmit data in a first slot which includes a first PDCCH and a first Physical Downlink Shared Channel (PDSCH), wherein the first PDCCH includes a first downlink control information (DCI) which is for use in receiving the first PDSCH; and
transmit data in a second slot includes a second PDCCH including a second DCI having a preemption indicator, the data in the first slot being transmitted prior to the data in the second slot,

wherein the preemption indicator included in the second DCI of the second PDCCH is for use by the UE in identifying that preemption applies to at least part of a resource of the first PDSCH.

7. The base station of claim 6 , wherein the information related to preemption includes information corresponding to a resource size in a time domain.

8. The base station of claim 6 , wherein the preempted part of the first PDSCH is for use in providing a low-latency or high-reliability communication service, and another part of the first PDSCH is for use in providing high-speed or broadband data communication service.

9. The base station of claim 6 , wherein the first DCI includes the unit information for feedback.

10. The base station of claim 6 , wherein the controller is further configured to:
receive a feedback, from the UE, wherein the feedback is related to the unit information which is transmitted using the first DCI.

11. A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
transmitting a radio resource control (RRC) message to a user equipment (UE), wherein the RRC message includes information related to preemption for use in configuring the UE to monitor Physical Downlink Control Channel (PDCCH);
transmitting data in a first slot which includes a first PDCCH and a first Physical Downlink Shared Channel (PDSCH), wherein the first PDCCH includes a first downlink control information (DCI) for use in receiving the first PDSCH; and
transmitting data in a second slot includes a second PDCCH including a second DCI having a preemption indicator, the data in the first slot being transmitted prior to the data in the second slot,
wherein the preemption indicator included in the second DCI of the second PDCCH is for use by the UE in identifying that preemption applies to at least part of a resource of the first PDSCH.

12. The non-transitory computer-readable medium of claim 11 , wherein the information related to preemption includes information corresponding to a resource size in a time domain.

13. The non-transitory computer-readable medium of claim 11 , wherein the preempted part of the first PDSCH is for use in providing a low-latency or high-reliability communication service, and another part of the first PDSCH is for use in providing high-speed or broadband data communication service.

14. The non-transitory computer-readable medium of claim 11 , wherein the first DCI includes the unit information for feedback.

15. The non-transitory computer-readable medium of claim 11 , wherein the operations further comprising: receiving a feedback, from the UE, wherein the feedback is related to the unit information which is transmitted using the first DCI.
