FIELD: information technology.
SUBSTANCE: invention relates to a multiple input multiple output (MIMO) communication system and particularly to codebook information in a MIMO communication system. The apparatus for generating a codebook includes a codebook generator. The codebook generator is configured to generate a 4-bit precoding codebook for eight transmitting antennae for use in a closed-loop single-user MIMO (SU-MIMO) scheme. According to aspects of the present invention, it is possible to generate a precoding codebook for use in systems with eight transmitting antennae.
EFFECT: high efficiency of transmitting and receiving data.
