and transmitting or receiving a signal to or from the serving cell, using the received group information of the serving cell and the neighboring cells and the uplink/downlink configuration information for each group, wherein the group information includes information on groups of cells clustered according to beams to be used by each cell or beam groups to which the beams belong. ## Claims ### Claim 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. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 1) 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. ### Claim 4 (depends on 1) 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. ### Claim 5 (depends on 1) 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. ### Claim 6 (depends on 5) 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. ### Claim 7 (depends on 1) 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. ### Claim 8 (depends on 1) 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. ### Claim 9 (depends on 1) 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. ### Claim 10 (depends on 8) The method of claim 8, further comprising: performing channel measurement in the predetermined time resource, the predetermined frequency resource, or the predetermined beam resource. ### Claim 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. ### Claim 12 (depends on 11) 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. ### Claim 13 (depends on 11) 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. ### Claim 14 (depends on 11) 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. ### Claim 15 (depends on 11) 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. ### Claim 16 (depends on 15) 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. ### Claim 17 (depends on 11) 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. ### Claim 18 (depends on 11) 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. ### Claim 19 (depends on 11) 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. ### Claim 20 (depends on 18) 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.
