Method for transmission and reception in wireless communication system, and apparatus therefor

1. A method for transmission and reception for a terminal in a wireless communication system, the method comprising:

receiving group information of a serving cell and a neighboring cell and uplink/downlink configuration information for each group; and

transmitting or receiving a signal to/from the serving cell using the received group information of the serving cell and the neighboring cell and the uplink/downlink configuration information for each group,

wherein the group information includes information regarding a cell group which is clustered according to a beam to be used by each cell or a beam group to which the beam belongs.

2. The method of claim 1 , wherein the uplink/downlink configuration information indicates how at least a part of a downlink region, an uplink region and a guard period region is configured in a predetermined time period or a subframe.

3. The method of claim 1 , wherein the uplink/downlink configuration information is dynamically or semi-statically changed in a unit of a predetermined time period.

4. The method of claim 1 , wherein the uplink/downlink configuration information for each group is determined in consideration of uplink/downlink configuration information of a different group.

5. The method of claim 1 , wherein the uplink/downlink configuration information includes information regarding a guard period region configured for a specific time resource, a specific frequency resource or a specific beam resource configured in a cell belonging to a corresponding group.

6. The method of claim 5 , wherein the information regarding the guard period region includes a length of the guard period region, the maximum range of the guard period region, or a maximum value of the guard period region.

7. The method of claim 1 , wherein the uplink/downlink configuration information includes information regarding a downlink and/or uplink portion configured for a specific time resource, a specific frequency resource or a specific beam resource configured in a cell belonging to a corresponding group.

8. The method of claim 1 , wherein a predetermined time resource, a predetermined frequency resource, or a predetermined beam resource indicated by the uplink/downlink configuration information for each group, is fixed to one of a downlink region, an uplink region, and a guard period region.

9. The method of claim 8 , further comprising:

performing channel measurement in the predetermined time resource, the predetermined frequency resource, or the predetermined beam resource.

10. The method of claim 1 , wherein a predetermined time resource, a predetermined frequency resource, or a predetermined beam resource indicated by the uplink/downlink configuration information for each group is configured to use a same TTI, a same TTI length, or a same subcarrier spacing.

11. A terminal performing transmission and reception in a wireless communication system, comprising:

a transmitter and a receiver; and

a processor configured to control the transmitter and the receiver,

wherein the processor is configured to:

receive group information of a serving cell and a neighboring cell and uplink/downlink configuration information for each group; and

transmit or receive signal to/from the serving cell using the received group information of the serving cell and the neighboring cell and the uplink/downlink configuration information for each group,

wherein the group information includes information regarding a cell group which is clustered according to a beam to be used by each cell or a beam group to which the beam belongs.

12. The terminal of claim 11 , wherein the uplink/downlink configuration information indicates how at least a part of a downlink region, an uplink region and a guard period region is configured in a predetermined time period or a subframe.

13. The terminal of claim 11 , wherein the uplink/downlink configuration information is dynamically or semi-statically changed in a unit of a predetermined time period.

14. The terminal of claim 11 , wherein the uplink/downlink configuration information for each group is determined in consideration of uplink/downlink configuration information of a different group.

15. The terminal of claim 11 , wherein the uplink/downlink configuration information includes information regarding a guard period region configured for a specific time resource, a specific frequency resource or a specific beam resource configured in a cell belonging to a corresponding group.

16. The terminal of claim 15 , wherein the information regarding the guard period region includes a length of the guard period region, the maximum range of the guard period region, or a maximum value of the guard period region.

17. The terminal of claim 11 , wherein the uplink/downlink configuration information includes information regarding a downlink and/or uplink portion configured for a specific time resource, a specific frequency resource or a specific beam resource configured in a cell belonging to a corresponding group.

18. The terminal of claim 11 , wherein a predetermined time resource, a predetermined frequency resource, or a predetermined beam resource indicated by the uplink/downlink configuration information for each group, is fixed to one of a downlink region, an uplink region, and a guard period region.

19. The terminal of claim 18 , wherein the processor is configured to perform channel measurement in the predetermined time, the predetermined frequency resource, or the predetermined beam resource.

20. The terminal of claim 11 , wherein a predetermined time resource, a predetermined frequency resource, or a predetermined beam resource indicated by the uplink/downlink configuration information for each group is configured to use a same TTI, a same TTI length, or a same subcarrier spacing.
