Abstract
A communication method and apparatus for coordinated multi-point (CoMP) transmission, is provided. Sizes of codebooks for a plurality of base stations may be adjusted based on a status of channels between a target terminal and a plurality of base stations. The terminal feeds back, to at least one of the plurality of base stations, channel direction information (CDI) including a number of bits of feedback.
