摘要： An electronic device at a base station end includes a processing circuit, the processing circuit being configured to: configure, in response to request signalling from a user equipment, an aperiodic beam-forming reference signal relevant to a first beam group for the user equipment, wherein the first beam group is determined by a base station according to channel state information periodically fed back by the user equipment; generate downlink control information, so as to indicate that the user equipment feeds back beam selection information according to the aperiodic beam-forming reference signal; determine, according to the beam selection information, one or a plurality of candidate beams and one or a plurality of corresponding second pre-coding codebooks; and determine an effective pre-coding codebook based on the one or multiple second pre-coding codebooks.

摘要： An electronic device for a base station in a wireless communication system including processing circuitry configured to indicate a user equipment to report a first type of channel statement information based on a reference signal for the first type of channel statement information, wherein the base station serves the user equipment in a way of SU-MIMO, make a determination that a second type of channel statement information is required in a case that the base station changes the way serving the user equipment from SU-MIMO to MU-MIMO, and notify the user equipment to report the second type of channel statement information based on a reference signal for the second type of channel statement information.
