    摘要: Disclosed is a method for selecting an adaptive CoMP scheme for a user equipment. The user equipment selects a first CoMP set which can maximize a signal to interference-plus-noise ratio (SINR) from among CoMP sets while performing a first coordinate multi-point (CoMP) scheme. Then, the user equipment compares the current data transmission rate thereof and the required minimum data transmission rate thereof and the required minimum data transmission rate while performing the first CoMP scheme and selecting the first CoMP set. Subsequently, the user equipment which performs the first CoMP scheme selects a second CoMP scheme on the basis of the result of the comparison in accordance with a predetermined sequence of CoMP schemes.

    摘要: Disclosed is a method for performing a handoff in a CoMP cluster. A user equipment measures a signal to interference-plus-noise ratio (SINR) value of each of the CoMP sets constituted by the combination of a plurality of base stations in one CoMP cluster. Then, the user equipment transmits the SINR value of each of the CoMP sets to a serving base station through a pilot strength measurement message (PSMM). Subsequently, the user equipment receives, from the serving base station, a message which instructs a handoff determined through the transmitted signal to interference-plus-noise ratio (SINR) values.
