Disclosed is a method by which a terminal transmits and receives a signal in a multi cell-based wireless communication system. Particularly, the method comprises the steps of: transmitting, to a serving cell, capability information in which the number of supportable channel status information (CSI) processes is set to zero; receiving, from the serving cell, information on a neighboring cell through an upper layer signal as a response to the capability information; receiving a cell-specific reference signal from the neighboring cell; reporting, to the serving cell, the CSI estimated on the basis of the cell-specific reference signal; and receiving, from the neighboring cell, a user equipment specific reference signal and a data channel on the basis of the CSI.

The present invention relates to a wireless communication system and, more particularly, to a method for transmitting and receiving by a user equipment in a multi-cell based wireless communication system and an apparatus therefor.
3GPP LTE (3rd generation partnership project long term evolution hereinafter abbreviated LTE) communication system is schematically explained as an example of a wireless communication system to which the present invention is applicable.
FIG. 1 is a schematic diagram of E-UMTS network structure as one example of a wireless communication system. E-UMTS (evolved universal mobile telecommunications system) is a system evolved from a conventional UMTS (universal mobile telecommunications system). Currently, basic standardization works for the E-UMTS are in progress by 3GPP. E-UMTS is called LTE system in general. Detailed contents for the technical specifications of UMTS and E-UMTS refers to release 7 and release 8 of “3rd generation partnership project; technical specification group radio access network”, respectively.
FIG. 1 is a schematic diagram of E-UMTS network structure as one example of a wireless communication system;
FIGS. 2(a) and 2(b) are diagrams for structures of control and user planes of radio interface protocol between a 3GPP radio access network standard-based user equipment and E-UTRAN;
FIG. 3 is a diagram for explaining physical channels used for 3GPP system and a general signal transmission method using the physical channels;
In the following description, compositions of the present invention, effects and other characteristics of the present invention can be easily understood by the embodiments of the present invention explained with reference to the accompanying drawings. Embodiments explained in the following description are examples of the technological features of the present invention applied to 3GPP system.
In this specification, the embodiments of the present invention are explained using an LTE system and an LTE-A system, which is exemplary only. The embodiments of the present invention are applicable to various communication systems corresponding to the above mentioned definition. In particular, although the embodiments of the present invention are described in the present specification on the basis of FDD, this is exemplary only. The embodiments of the present invention may be easily modified and applied to H-FDD or TDD.
And, in the present specification, a base station can be named by such a comprehensive terminology as an RRH (remote radio head), an eNB, a TP (transmission point), an RP (reception point), a relay and the like.
