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.

The present invention relates to a method for transmitting a signal in a wireless communication system. The method includes channel coding a data stream using a first turbo encoded puncture pattern, and channel coding the data stream using a second turbo encoded puncture pattern. Preferably, the first turbo encoded puncture pattern is a turbo encoded puncture pattern of a first local operator infrastructure (LOI) and the second turbo encoded puncture pattern is a turbo encoded puncture pattern of a second LOI that neighbors the first LOI.
