CODEBOOK DETERMINATION METHOD AND APPARATUS, AND COMMUNICATION SYSTEM

摘要

Provided are a codebook determination method and apparatus, and a communication system. The codebook determination method comprises: on the basis of the number of antenna particles and/or the number of radio frequency chains, determining a first codebook for radio frequency pre-coding, wherein the antenna particles in the same polarization direction in a column of antennas in the vertical direction form one or more virtual antenna ports, and the one or more virtual antenna ports are connected to a plurality of radio frequency chains; and on the basis of the number of antenna particles or the number of radio frequency chains, determining a second codebook for baseband pre-coding. By means of embodiments of the present invention, the mixed pre-coding of the baseband and the radio frequency can be performed. The present invention is suitable for the application of a large-scale MIMO system, and can achieve an effective compromise between system performance and complexity.
