Abstract: A method of constructing a codebook with multiple resolution in a wireless communication system includes constructing, with a user equipment (UE), a high resolution codebook using a low resolution codebook, and transmitting, from the UE to a base station (BS), normal Channel State Information (CSI) feedback or advanced CSI feedback based on an instruction from the BS or determination in the UE. The normal CSI feedback includes CSI generated based on the low resolution codebook. The advanced CSI feedback includes CSI generated based on the high resolution codebook. The low resolution codebook reuses beams selected based on a beam selection scheme under a Long Term Evolution (LTE) standard. The high resolution codebook is a high resolution codebook for rank 2. The high resolution codebook reuses a 1-layer codebook of a LTE standard or one of 3-layer, 5-layer, and 7-layer codebook of the LTE standard.

Abstract: A method is presented for transmitting uplink control information and a mobile station. The method for transmitting the uplink control information includes: adding padding bits to initial control information to generate uplink control information, where the initial control information includes first information having a same number of bits for RANKs of different channel matrices and second information having a same or different number of bits for RANKs of different channel matrices; and transmitting the uplink control information.
