Abstract
The invention provides an electronic device for user equipment and a base station in a wireless communication system and a method. The electronic device for user equipment in the wireless communication system comprises a circuit. The circuit is configured to measure a downlink channel based on control signaling from the base station; the number of data flows received by the user equipment at the same time is determined; based on the downlink channel measurement result and a selection criterion depending on the number of the data flows, two pre-coding matrixes are selected from a pre-coding codebook; a first pre-coding matrix indication and a second pre-coding matrix indication corresponding to the pre-coding matrixes meeting the selection criterion are determined for feeding channel state information back to the base station; and the first pre-coding matrix indication and the second pre-coding matrix indication are applied to an uplink channel of the user equipment, and the channel state information is fed back.
