Title (EN) METHOD FOR TRANSMITTING AND RECEIVING SYNCHRONIZATION SIGNAL IN COMMUNICATION SYSTEM

Abstract:
(EN) A method for transmitting and receiving a synchronization signal in a communication system is disclosed. An operation method of a terminal comprises the steps of: receiving, from a base station, a synchronization signal and an SS block including a PBCH; estimating y bits among x bits for indicating a number of a system frame on which the SS block has been transmitted, on the basis of a sequence used for the scrambling of the PBCH included in the SS block; decoding the PBCH included in the SS block so as to acquire z bits among the x bits for indicating the number of the system frame on which the SS block has been transmitted; and confirming the number of the system frame on the basis of the y bits and the z bits. Therefore, the performance of a communication system can be improved.
(FR) La présente invention se rapporte à un procédé permettant de transmettre et de recevoir un signal de synchronisation dans un système de communication. Un procédé de fonctionnement d'un terminal comprend les étapes consistant : à recevoir, d'une station de base, un signal de synchronisation et un bloc SS comprenant un canal PBCH ; à estimer y bits parmi x bits pour indiquer un numéro d'une trame système sur laquelle le bloc SS a été transmis, sur la base d'une séquence utilisée pour le brouillage du canal PBCH inclus dans le bloc SS ; à décoder le canal PBCH inclus dans le bloc SS de sorte à acquérir z bits parmi les x bits pour indiquer le numéro de la trame système sur laquelle le bloc SS a été transmis ; et à confirmer le numéro de la trame système sur la base des y bits et des z bits. Par conséquent, les performances d'un système de communication peuvent être améliorées.
(KO) 통신 시스템에서 동기 신호의 송수신 방법이 개시된다. 단말의 동작 방법은, 동기 신호 및 PBCH를 포함하는 SS 블록을 기지국으로부터 수신하는 단계, 상기 SS 블록에 포함된 상기 PBCH의 스크램블링을 위해 사용된 시퀀스에 기초하여 상기 SS 블록이 전송된 시스템 프레임의 번호를 지시하는 x 비트들 중에서 y 비트들을 추정하는 단계, 상기 SS 블록에 포함된 상기 PBCH를 디코딩함으로써 상기 SS 블록이 전송된 상기 시스템 프레임의 번호를 지시하는 상기 x 비트들 중에서 z 비트들을 획득하는 단계, 및 상기 y 비트들 및 상기 z 비트들에 기초하여 상기 시스템 프레임의 번호를 확인하는 단계를 포함한다. 따라서 통신 시스템의 성능이 향상될 수 있다.
