Abstract

To execute communication by using multi-dimensional antenna configuration in communication system.SOLUTION: A WTRU receives communication from a base station via one or multiple channels. Communication is executed using multiple component codebooks. The WTRU sends the channel state information (CSI) feedback for each component codebook, to be considered when executing communication, to the base station. Based on the channel measurement, the WTRU determines the CSI feedback for each component codebook. The component codebook may includes a horizontal component codebook and/or a vertical component codebook. The WTRU may transmit the CSI feedback for each component codebook individually or in the form of a composite codebook to the base station. The WTRU may determine a composite codebook as a function of the component codebook.SELECTED DRAWING: Figure 13
