Communication method using multiple transmission points, and apparatus for same

摘要

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus for transmitting channel quality information by a terminal in a wireless communication system, the method comprising: receiving information on a plurality of transmission nodes capable of performing CoMP transmission; transmitting first channel state information on one or more preferred transmission nodes from among the plurality of transmission nodes; receiving pattern information consisting of a plurality of combinations of CoMP sets, each of which corresponds to a relevant time interval according to the pattern information; and performing an operation for transmitting second channel state information on the combination of CoMP sets corresponding to a subframe n.

1. A method for transmitting channel quality information by a user equipment in a wireless communication system that supports Coordinated Multiple Point (CoMP) transmission and reception, the method comprising:
receiving information according to a plurality of transmission nodes capable of performing CoMP transmission and reception; transmitting first channel state information according to one or more preferred transmission nodes among the plurality of transmission nodes; receiving pattern information configured by a plurality of CoMP set combinations, each of which corresponds to a relevant time interval in accordance with the pattern information; and performing an operation for transmitting second channel state information according to a CoMP set combination corresponding to a subframe n, wherein the second channel state information is transmitted when the CoMP set combination corresponding to the subframe n is overlapped with the one or more preferred transmission nodes, and the second channel state information is dropped when the CoMP set combination corresponding to the subframe n is not overlapped with the one or more preferred transmission nodes.
