Wireless communication using multi-dimensional antenna configuration
Abstract
Communications may be performed in a communications system using multi-dimensional antenna configurations. A WTRU may receive communications from a base station via one or more channels. The communications may be performed using multiple component codebooks. The WTRU may send channel state information (CSI) feedback for each component codebook to the base station for consideration when performing communications with the WTRU. The WTRU may determine the CSI feedback for each component codebook based on channel measurements. The component codebooks may include a horizontal component codebook and/or a vertical component codebook. The WTRU may send the CSI feedback for each component codebook to the base station independently or in the form of a composite codebook. The WTRU may determine a composite codebook a function of the component codebooks.
