Abstract

To solve the above-mentioned problem, the method for transmitting and receiving a signal by user equipment (UE) through one or more cells, according to one embodiment of the present specification, comprises the steps of: receiving, from a base station, a first message indicating whether one or more cells usable by the UE are enabled; determining which cells to enable or disable on the basis of the first message; and enabling or disabling the selected cells. According to the embodiment of the present specification, by aggregating carriers amongst different base stations, a possibility for the UE to transmit and receive high-speed data through carrier aggregation can increase.

First claim

What is claimed is:

1 . A method by a terminal in a communication system, the method comprising:
receiving first control information for a secondary cell group on a primary cell group, the first control information including information for at least one serving cell of the secondary cell group; acquiring master information block (MIB) on a first serving cell of the secondary cell group, a physical uplink control channel (PUCCH) being configured in the first serving cell; identifying system frame number (SFN) for the at least one serving cell of the secondary cell group based on the acquired MIB; and transmitting uplink control information on the first serving cell of the secondary cell group based on the identified SFN.

2 . The method of claim 1 , further comprising:
identifying synchronization information for downlink of the first serving cell of the secondary cell group in response to the first control information.

3 . The method of claim 1 , wherein the at least one serving cell of the secondary cell group except for the first serving cell is in deactivated state in response to the first control information.

4 . The method of claim 1 , wherein the uplink control information includes at least one of a channel quality reporting, scheduling request configuration and sounding reference signal configuration.

5 . The method of claim 1 , wherein the uplink control information is transmitted in response to a procedure of a random access associated with the first serving cell of the secondary cell group.

6 . A method by a base station in a communication system, the method comprising:
transmitting first control information for a secondary cell group on a primary cell group, the first control information including information for at least one serving cell of the secondary cell group; transmitting master information block (MIB) on a first serving cell of the secondary cell group, a physical uplink control channel (PUCCH) being configured in the first serving cell; and receiving uplink control information on the first serving cell of the secondary cell group based on system frame number (SFN) identified based on the MIB, the SFN being identified for the at least one serving cell of the secondary cell group.

7 . The method of claim 6 , wherein synchronization information for downlink of first serving cell of the secondary cell group is identified in response to the first control information.

8 . The method of claim 6 , wherein the at least one serving cell of the secondary cell group except for the first serving cell is in deactivated state in response to the first control information.

9 . The method of claim 6 , wherein the uplink control information includes at least one of a channel quality reporting, scheduling request configuration and sounding reference signal configuration.

10 . The method of claim 6 , wherein the uplink control information is received in response to a procedure of a random access associated with the first serving cell of the secondary cell group.

11 . A terminal in a communication system, the terminal comprising:
a transceiver; and at least one processor coupled with the transceiver and configured to: receive first control information for a secondary cell group on a primary cell group, the first control information including information for at least one serving cell of the secondary cell group; acquire master information block (MIB) on a first serving cell of the secondary cell group, a physical uplink control channel (PUCCH) being configured in the first serving cell; identify system frame number (SFN) for the at least one serving cell of associated with the secondary cell group based on the acquired MIB; and transmit uplink control information on the first serving cell of the secondary cell group based on the identified SFN.

12 . The terminal of claim 11 , wherein the at least one processor is further configured to identify synchronization information for downlink of the first serving cell of the secondary cell group in response to the first control information.

13 . The terminal of claim 11 , wherein the at least one serving cell of the secondary cell group except for the first serving cell is in deactivated state in response to the first control information.

14 . The terminal of claim 11 , wherein the uplink control information includes at least one of a channel quality reporting, scheduling request configuration and sounding reference signal configuration.

15 . The terminal of claim 11 , wherein the uplink control information is transmitted in response to a procedure of a random access associated with the first serving cell of the secondary cell group.

16 . A base station in a communication system, the base station comprising:
a transceiver; and at least one processor coupled with the transceiver and configured to: transmit first control information for a secondary cell group on a primary cell group, the first control information including information for at least one serving cell of the secondary cell group; transmit master information block (MIB) on a first serving cell of the secondary cell group, a physical uplink control channel (PUCCH) being configured in the first serving cell; and receive uplink control information on the first serving cell of the secondary cell group based on system frame number (SFN) identified based on the MIB, the SFN being identified for the at least one serving cell of the secondary cell group.

17 . The base station of claim 16 , wherein synchronization information for downlink of the first serving cell of the secondary cell group is identified in response to the first control information.

18 . The base station of claim 16 , wherein the at least one serving cell of the secondary cell group except for the first serving cell is in deactivated state in response to the first control information.

19 . The base station of claim 16 , wherein the uplink control information includes at least one of a channel quality reporting, scheduling request configuration and sounding reference signal configuration.

20 . The base station of claim 16 , wherein the uplink control information is received in response to a procedure of a random access associated with the first serving cell of the secondary cell group.
