PRECODING MATRIX CODEBOOK DESIGN FOR ADVANCED WIRELESS COMMUNICATIONS SYSTEMS

摘要

Methods and apparatus of constructing rank-1 and/or rank-2 codebooks for advanced communication systems with 4 transmit antennas and two-dimensional (2D) MXN transmit antenna elements are provided. A double-codebook structure is considered for 4-Tx antenna configuration. Single-codebook and double-codebook structures are considered for two-dimensional (2D) MXN transmit antenna elements.
