METHODS AND APPARATUS TO GENERATE MULTIPLE ANTENNAS TRANSMIT PRECODING CODEBOOK

摘要

A device and method for generating a codebook. The device includes a generator. The codebook generator is configured to generate a precoding codebook using an 8-PSK alphabet-based 4 bits 4 TX and 8 TX antennas for use in a closed-loop SU-MIMO scheme. According to aspects of the present disclosure, it is possible to generate a precoding codebook for use in 8 Transmission Antenna systems.
