Abstract: Disclosed herein is a method for reporting channel state information (CSI) of a terminal in a wireless communication system. The method includes: measuring a CSI-RS (reference signal) transmitted from a base station through multiple panels; and reporting CSI generated based on the CSI-RS measurement to the base station, wherein, when the terminal reports a WB (Wideband) panel corrector and SB (Subband) panel corrector for the multiple panels as the CSI, the WB panel corrector and the SB panel corrector are reported with different bit widths.

Abstract: A ceiling fan or similar air-moving device can include a motor for rotating one or more blades to drive a volume of air about a space. A connector can be used to connect the blade to a blade iron to mount the blade to the motor. The connector can include a set of receptacles configured to insert into openings on the blade, with the set of receptacles connected by a set of arms. A set of mount posts on the blade iron can seat within the receptacles to mount the blade to the blade iron.

Abstract: Disclosed is a precoding method for generating, from a plurality of baseband signals, a plurality of precoded signals that are transmitted in the same frequency bandwidth at the same time. According to the precoding method, one matrix is selected from among matrices defining a precoding process that is performed on the plurality of baseband signals by hopping between the matrices. A first baseband signal and a second baseband signal relating to a first coded block and a second coded block generated by using a predetermined error correction block coding scheme satisfy a given condition.
