Abstract: A disclosure of the present specification provides a method for transmitting data by a transmitter. The method may comprise the steps of: when a transport block (TB) is divided into n data blocks, adding additional information after each of the n data blocks; and adding a cyclic redundancy check (CRC) after the last additional information. Here, the CRC may be generated on the basis of the n data blocks, and the n pieces of additional information added after each of data blocks.

Abstract: Disclosed herein are a method and apparatus for transmitting/receiving an uplink signal. A user equipment receives information indicating a data transmission code rate for uplink data. The user equipment channel-codes the uplink data using a channel code corresponding to a channel code rate. The channel code rate is determined among a plurality of predefined channel code rates based on the data transmission code rate. The user equipment transmits the channel coded uplink data.

Abstract: A method for transmitting a reference signal for supporting a plurality of antennas to a User Equipment (UE) at a Base Station (BS) in a wireless communication system is disclosed. The method includes grouping the plurality of antennas into antenna groups comprising a predetermined number of antenna ports, transmitting resource information about a reference signal for at least one antenna group of the antenna groups, and transmitting the reference signal for the at least one antenna group to the UE based on the resource information.

Abstract: The method comprises: a step in which the base station transmits to a terminal configuration information related to the beam restricted sub-frame; and a step in which the base station transmits downlink data to the terminal via a sub-frame. The sub-frame includes the beam restricted sub-frame and a normal sub-frame, setting information includes information indicating a sub-frame set as the beam restricted sub-frame among multiple sub-frames, the beam restricted sub-frame is a sub-frame transmitted only based on a first beam subset, the normal sub-frame is a sub-frame transmitted based on the first beam subset and a second beam subset, the first beam subset is the set of beams generated based on a first precoding matrix set, and the second beam subset is the set of beams generated based on a second precoding matrix set including the first precoding matrix set.
