SUBSCRIBER APPARATUS AND BASE STATION AND METHOD FOR SELECTING REMOTE RADIO HEADS

摘要

The present invention relates to a User Equipment (UE), a base station and a method for selecting a Remote Radio Head (RRH). A UE, including: a storage unit configured to store a code book including a plurality of precoding matrixes which contain a precoding matrix having an element zero corresponding to an antenna; a precoding matrix selection unit configured to select the precoding matrix to be used according to the code book stored in the storage unit; and a report unit configured to report an index of the precoding matrix selected by the precoding matrix selection unit. In the preferred embodiments, elements of a same precoding matrix for antennas of same RRH are all zero or non-zero.
