A method for, at a user equipment, UE, capable of being served by a coordinated multiple point transmission and reception, CoMP, set consisting of a plurality of base stations in a wireless communication system, transmitting channel state information to at least one of the base stations, the method comprising: receiving resource allocation information on allocation of time-frequency resources used to transmit supplemental channel state information related to at least one neighboring base station, which does not participate in a CoMP scheme being switched between dynamic point selection, DPS, joint transmission, JT, and coordinated scheduling/coordinated Beamforming, CS/CB, from a serving base station of the UE; transmitting supplemental channel state information related to the at least one neighboring base station to the serving base station, based on a part of time-frequency resources allocated for transmission of channel state information related to the serving base station, based on the resource allocation information, wherein the supplemental channel state information includes wideband channel state information related to the at least one neighboring base station; and transmitting the subband channel state information, while omitting the wideband channel state information, related to the at least one neighboring base station for a new CoMP scheme during a predetermined period during which the supplemental channel state information is valid after switching to the new CoMP scheme when the at least one neighboring base station participates in the new CoMP scheme, wherein the supplemental channel state information is used either to determine a new base station for transmitting data when the DPS is used for the CoMP scheme or estimate channel state information for the new CoMP scheme after the switching to the new CoMP scheme during the predetermined period when the at least one neighboring base station participates in the new CoMP scheme. receiving resource allocation information on allocation of time-frequency resources used to transmit supplemental channel state information related to at least one neighboring base station, which does not participate in a CoMP scheme being switched between dynamic point selection, DPS, joint transmission, JT, and coordinated scheduling/coordinated Beamforming, CS/CB, from a serving base station of the UE; transmitting supplemental channel state information related to the at least one neighboring base station to the serving base station, based on a part of time-frequency resources allocated for transmission of channel state information related to the serving base station, based on the resource allocation information, wherein the supplemental channel state information includes wideband channel state information related to the at least one neighboring base station; and transmitting the subband channel state information, while omitting the wideband channel state information, related to the at least one neighboring base station for a new CoMP scheme during a predetermined period during which the supplemental channel state information is valid after switching to the new CoMP scheme when the at least one neighboring base station participates in the new CoMP scheme, wherein the supplemental channel state information is used either to determine a new base station for transmitting data when the DPS is used for the CoMP scheme or estimate channel state information for the new CoMP scheme after the switching to the new CoMP scheme during the predetermined period when the at least one neighboring base station participates in the new CoMP scheme. <EOS>
