Abstract

An operation method of a terminal in a communication system includes receiving an RRC message from a base station, the RRC message including configuration information of a plurality of CGs; transmitting a first signal to the base station through a first CG resource indicated by a first CG among the plurality of CGs; receiving a control message from the base station; and based on a result of receiving the control message, transmitting a second signal to the base station through a second CG resource indicated by an activated second CG among the plurality of CGs, wherein a pattern of the first CG resource is different from a pattern of the second CG resource.

Claims (23)

1. An operation method of a terminal in a communication system, the operation method comprising:

receiving a radio resource control (RRC) message from a base station, the RRC message including configuration information of a plurality of configured grants (CGs);

transmitting a first signal to the base station through a first CG resource indicated by a first CG among the plurality of CGs;

receiving a control message indicating activation of second CG among the plurality of CGs from the base station; and

based on a result of receiving the control message, transmitting a second signal to the base station through a second CG resource indicated by the second CG activated by the control message,

wherein a pattern of the first CG resource is different from a pattern of the second CG resource, and the plurality of CGs are mapped to same data radio bearer (DRB) connected with the base station.

2. The operation method according to claim 1 , wherein the pattern of the second CG resource is a pattern having at least one of a periodicity and a starting time which are different from a periodicity and a starting time of the pattern of the first CG resource.

3. The operation method according to claim 2 , wherein the RRC message further includes at least one of a periodicity and a starting time of a pattern of each of the plurality of CGs.

4. The operation method according to claim 1 , wherein the first signal includes time sensitive network (TSN) data generated according to a preconfigured periodicity, and the preconfigured periodicity is different from a periodicity of each of the plurality of CGs.

5. The operation method according to claim 1 , wherein the control message includes at least one of an indicator of the second CG and an indicator of a logical channel mapped to the second CG.

6. The operation method according to claim 5 , wherein a priority of the logical channel mapped to the second CG is configured based on configuration information of the second CG, and the second signal is transmitted through a resource indicated by the second CG activated based on information on the priority of the logical channel.

7. An operation method of a base station for receiving a signal including data, the operation method comprising:

transmitting a radio resource control (RRC) message to a terminal, the RRC message including configuration information of a configured grant (CG);

receiving a first signal from the terminal through a CG resource of the CG;

when a latency requirement is not satisfied by using the CG, transmitting a control message to the terminal; and

receiving a second signal from the terminal through a CG resource reconfigured based on the control message,

wherein the CG is mapped to a data radio bearer (DRB) connected with the terminal.

8. The operation method according to claim 7 , wherein the data is time sensitive network (TSN) data generated according to a preconfigured periodicity, and the preconfigured periodicity of the TSN data is different from a periodicity of the CG.

9. The operation method according to claim 7 , wherein the RRC message includes configuration information of a plurality of CGs indicating different patterns of CG resources, and the first signal is transmitted through a resource indicated by a first CG among the plurality of CGs.

10. The operation method according to claim 9 , wherein the reconfigured CG is a second CG excluding the first CG among the plurality of CGs, and the control message indicates activation of the second CG.

11. The operation method according to claim 10 , wherein the control message includes at least one of an indicator of the second CG and an indicator of a logical channel mapped to the second CG.

12. The operation method according to claim 7 , wherein the RRC message further includes time domain shift information including a time point at which the CG resource is shifted and a time by which the CG is shifted.

13. The operation method according to claim 12 , wherein the second signal is transmitted through a resource indicated by the reconfigured CG which is shifted in a time domain based on the time domain shift information.
