Abstract: According to the present invention, a common reference signal is transmitted in a subframe configured to receive the common reference signal and/or a fixed subframe predefined to receive the common reference signal, from among a plurality of subframes within a frame. In the present invention, the common reference signal is transmitted in every subframe within a legacy frame duration. However, the common reference signal is transmitted in said configured subframe and/or said fixed subframe within a frame duration which is not a legacy frame duration.

Abstract: In the present specification, settings for a link direction and link availability of a time resource for a DU child link may be referred to as DU setting. The resource types from an IAB node DU perspective are UL, DL, and F, and the settings for availability may be classified into NA, hard resources, and soft resources, respectively. Specifically, the IAB node may receive resource setting information, wherein the resource setting information may include link direction information and availability information. The link direction information may indicate whether the type of a specific resource is UL, DL, or F, and the availability information may indicate whether a specific resource is a hard resource, an NA resource, or a soft resource. Considering the feature of sharing resources in a TDM scheme between a MT and a DU in the IAB node, the present specification proposes a feature to be had by a slot format setting for the IAB node.

Abstract: The present specification provides a method for transmitting and receiving data by a relay node in a wireless communication system and an apparatus therefor. The relay node receives configuration information from a network node, wherein the configuration information may include a timing offset for transmitting downlink data. The relay node transmits the downlink data to a second relay node on the basis of the configuration information, in which transmission timing of the downlink data may be determined on the basis of the timing offset and a timing advance (TA).

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: A method and an apparatus for transmitting/receiving downlink control information are provided. Downlink control information about a data channel may be transmitted through one of a plurality of decoding candidates. Depending on whether the data channel is based on a first sub-frame or a second sub-frame, the downlink control information is transmitted through one of the candidates for the first sub-frame or one of the candidates for the second sub-frame, from among the plurality of decoding candidates. The second sub-frame is shorter than the first sub-frame and can be set within the first sub-frame.
