Description	La présente invention concerne un procédé et un système de communication permettant de faire converger un système de communication de 5ème génération (5G) permettant de prendre en charge des débits de données supérieurs, au-delà de ceux d'un système de 4ème génération (4G), avec une technologie de l'Internet des objets (IDO). La présente invention peut être appliquée à des services intelligents basés sur la technologie de communication 5G et sur la technologie associée à l'IDO, tels qu'une maison intelligente, des bâtiments intelligent, des villes intelligentes, des voitures intelligentes, des voitures connectées, des soins de santé, l'enseignement numérique, le commerce de détail intelligent, et des services de sécurité et de sûreté. L'invention porte sur un procédé de transmsission d'informations de commande en liaison montante dans un système de communication sans fil. Le procédé consiste à recevoir des informations de configuration de retour d'informations d'état de canal (CSI) provenant d'une station de base, à générer des CSI comprenant au moins l'un d'un indicateur de ressource de signal de référence CSI (CRI), d'un indicateur de rang (RI), d'un indicateur de matrice de précodage (PMI), ou d'un indicateur de qualité de canal (CQI) sur la base des informations de configuration de rétroaction de CSI, à identifier une séquence d'informations comprenant les CSI, à coder la séquence d'informations à l'aide d'un code polaire, et à transmettre la séquence d'informations codées à une station de base. Le CRI et le RI sont placés avant des bits de remplissage dans la séquence d'informations et le PMI et le CQI sont placés après les bits de remplissage dans la séquence d'informations.
Abstract	The present disclosure relates to a communication method and system for converging a 5th-Ggeneration (5G) communication system for supporting higher data rates beyond a 4th-Ggeneration (4G) system with a technology for Internet of Tthings (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart homes, smart buildings, smart cities, smart cars, connected cars, health care, digital education, smart retail, security, and safety services. A method of transmitting uplink control information in a wireless communication system is provided. The method includes receiving channel state information (CSI) feedback configuration information from a base station, generating (CSI) including at least one of a CSI reference signal resource indicator (CRI), a rank indicator (RI), a precoding matrix indicator (PMI), or a channel quality indicator (CQI) based on the CSI feedback configuration information, identifying an information sequence including the CSI, encoding the information sequence using a polar code, and transmitting the encoded information sequence to a base station. The CRI and the RI are placed before padding bits in the information sequence and the PMI and the CQI are placed after the padding bits in the information sequence.
