Abstract: front page image
(EN) A method and a device for performing communication by using a non-orthogonal code multiple access scheme in a wireless communication system are provided. Particularly, a terminal receives control information from a base station. The terminal modulates or demodulates a terminal-specific NCC on the basis of the control information. The terminal performs the non-orthogonal code multiple access scheme by using the terminal-specific NCC. The control information includes information on a codeword composed of a Grassmannian sequence. The codeword is included in a codebook predefined for the non-orthogonal code multiple access scheme. Each coefficient of the Grassmannian sequence is quantized on the basis of an M-quadrature amplitude modulation (M-QAM) constellation.
(FR) La présente invention concerne un procédé et un dispositif qui permettent d'établir une communication à l'aide d'un système d'accès multiple par code non-orthogonal dans un système de communication sans fil. Plus particulièrement, un terminal reçoit des informations de commande d'une station de base. Le terminal module ou démodule un NCC spécifique à un terminal sur la base des informations de commande. Le terminal exécute le système d'accès multiple par code non-orthogonal à l'aide du NCC spécifique à un terminal. Les informations de commande comprennent des informations sur un mot de code composé d'une séquence Grassmannienne. Le mot de code est compris dans un livre de codes prédéfini pour le système d'accès multiple par code non-orthogonal. Chaque coefficient de la séquence Grassmannienne est quantifié sur la base d'une constellation de modulation d'amplitude en quadrature M (M-QAM).
(KO) 무선통신시스템에서 비직교 부호 다중 접속 기법을 사용하여 통신을 수행하는 방법 및 기기가 제공된다. 구체적으로, 단말은 기지국으로부터 제어정보를 수신한다. 단말은 상기 제어정보를 기반으로 단말 특정 NCC를 변조 또는 복조한다. 단말은 단말 특정 NCC를 사용하여 상기 비직교 부호 다중 접속 기법을 수행한다. 제어정보는 grassmannian 시퀀스로 구성되는 코드워드에 대한 정보를 포함한다. 코드워드는 비직교 부호 다중 접속 기법을 위해 기정의된 코드북에 포함된다. grassmannian 시퀀스의 각 계수(coefficient)는 M-QAM(Quadrature Amplitude Modulation) 성상도를 기반으로 양자화된다.
