Abstract: Disclosed are a method for dividing a carrying block of a Low Density Parity Check (LDPC) code and an apparatus therefor. The method for dividing a LDPC code of the present disclosure can obtain a high throughput by using a limited size of shifting network. Moreover, it is possible to prevent degradation in performance due to a minimum size of code block by performing shortening for a large size of code block while minimizing the number of code blocks. Furthermore, in selection of a minimum size of code block, since a minimum size of code block is selected on the basis of shortening for a relatively large size of code block, it is possible to increase the size of the minimum size of code block.

Abstract: Provided are a method and device for transmitting a scheduling request in a wireless communication system. In detail, a terminal receives, from a base station, resource allocation information for indicating a semi-persistent scheduling request and a scheduling request resource. The terminal receives, from the baste station, a first indicator for indicating whether the semi-persistent scheduling resource is activated and a second indicator for indicating whether the scheduling request resource is activated. The terminal determines whether the scheduling request can be transmitted on the basis of the first indicator and the second indicator. The terminal transmits the scheduling request to the base station via the scheduling request resource indicated by the resource allocation information.

Abstract: Provided are a method and an apparatus for obtaining downlink synchronization in a wireless communication system. The wireless communication system that is proposed has an environment in which the resource location of a downlink synchronization signal changes due to the application of multiple numerology. Particularly, a terminal receives synchronization signal information from a base station. The synchronization signal information includes candidate resources from which synchronization signals with respect to a tracking area can be transmitted, and the order of detecting the synchronization signals from the candidate resource win respect to the tracking area. The terminal detects the synchronization signal on the basis of the synchronization signal information.
