    摘要: Disclosed are a method for estimating a channel state in a CoMP operation of a terminal and a method for generating channel state information of a base station. A terminal can measure strength or an interference level of a signal of each cell using a reference signal received from each cell for performing the CoMP operation. In addition, the terminal can measure the sum of the interference levels of the cells which do not perform the CoMP operation using a region from which a reference signal of a serving cell of each cell is transmitted. In addition, the terminal can transmit to the serving base station the strength of the interference level of the signal of each cell for performing the measured CoMP operation and the sum of the interference levels of the cells which do not perform the CoMP operation.

    摘要: Disclosed is a method for transmitting a CoMP reference signal for accurate channel estimation. The CoMP reference signal to be transmitted to a terminal which performs a CoMP operation in a multi-cell environment is a cell-specific reference signal or a CoMP-zone-specific reference signal. A method for transmitting the cell-specific reference signal uses an ID of a CoMP set constituted by cells that perform a CoMP operation, or does not apply a frequency shift value while using the ID of a relevant cell, or uses an ID of a serving cell or a frequency shift value of the serving cell. The cell-specific reference signal is transmitted using a preset specific resource region. A method for transmitting the CoMP-zone-specific reference signal is configured such that the pattern of the sequence of CoMP reference signals varies in each of the CoMP zones, and the pattern can be set in advance. In addition, the reference signal is multiplexed and transmitted using an orthogonal code resource in the event that reference signal is transmitted to a plurality of terminals using the same CoMP zone.

    摘要: A method of efficiently transmitting CoMP feedback information from an user equipment, which performs CoMP operation, in a wireless communication system to reduce inter-cell interference is disclosed. The user equipment requests a neighboring cell, which affects the user equipment through interference, to restrict use of a specific beam pattern group in a serving cell direction. In this case, whether the user equipment will request such restriction is determined based on a channel status value of the user equipment. If the user equipment determines to request such restriction, the user equipment transmits a request message to a serving base station, the request message requesting to restrict use of the specific beam pattern group. In this case, the user equipment performs scheduling and requests a specific neighboring cell to restrict use of the specific beam pattern group at a specific resource region.

    摘要: Disclosed is a method for efficiently transceiving information required for implementing a multi-cell-based CoMP MU-MIMO scheme. For this purpose, a base station which performs CoMP operation generates: (A) a reference signal sequence on the basis of a specific base station; or generates (B) the same reference signal sequence on the basis of a CoMP ID, and transmits the generated sequence to user equipment. To support an MU-MIMO scheme and to perform a joint processing method, the base station must additionally transmit CoMP reference signal sequence information, frequency shift information, etc. to the user equipment in said (A) case, and generates a CoMP reference signal on the basis of a preset CoMP set ID and transmits the generated signal to the user equipment in said (B) case.
