transmitting, by the second serving BS, the information associated with the plurality of BSs to a terminal;

receiving, by the second serving BS, channel information associated with the plurality of BSs from the terminal;

transmitting, by the second serving BS, the channel information associated with the plurality of BSs to the first serving BS;

receiving, by the second serving BS, control information from the first serving BS; and

transmitting, by the second serving BS, the control information to the terminal,

wherein the control information includes information, determined based on the channel information associated with the plurality of BSs, related to a change of an operation of the first serving BS and the second serving BS and at least one other second serving BS.

14. The method of claim 13, wherein the control information includes information related to a frame at which the change of operation is to be applied.

15. The method of claim 13, wherein the information related to a change of an operation includes information about whether the operation of the first serving BS is replaced with the second serving BS and the at least one other second serving BS.

16. The method of claim 13,

wherein the information associated with the plurality of BSs includes an Identification (ID) of the first serving BS, an ID of the second serving BS, and an ID of the at least one other second serving BS.

17. The method of claim 16, wherein the channel information includes a pre-defined channel quality indicator (CQI) code.
