Abstract:
(EN) The present disclosure relates to an operation of a terminal and a base station for transmission and reception of channel state information in a frame structure of a short transmission time interval of a 3GPP LTE/LTE-Advanced system. In an embodiment, provided are a method and an apparatus for transmitting, by a terminal, channel state information (CSI) in a frame structure of a short transmission time interval (sTTI), the method comprising the steps of: receiving type information of a short transmission time interval from a base station through an RRC signaling; determining a channel state information transmission period of a short transmission time interval on the basis of the type information of the short transmission time interval; determining channel state information to be transmitted to the base station according to a channel state information transmission period of a general transmission time interval and the channel state information transmission period of the short transmission time interval; and transmitting the channel state information to be transmitted to the base station through an uplink control channel of a short transmission time interval, wherein the general transmission time interval is set to 12 or 14 symbols, and the short transmission time interval is set to 2, 4, or 7 symbols.
(FR) La présente invention concerne l'exploitation d'un terminal et d'une station de base pour la transmission et la réception d'informations d'état de canal dans une structure de trame d'un intervalle de temps de transmission court d'un système 3GPP LTE/LTE avancé. Dans un mode de réalisation, l'invention concerne un procédé et un appareil pour la transmission, par un terminal, d'informations d'état de canal (CSI) dans une structure de trame d'un intervalle de temps de transmission court (sTTI), le procédé comprenant : la réception d'informations de type d'un intervalle de temps de transmission court en provenance d'une station de base par l'intermédiaire d'une signalisation RRC; la détermination d'une période de transmission d'informations d'état de canal d'un intervalle de temps de transmission court en fonction des informations de type de l'intervalle de temps de transmission court; la détermination d'informations d'état de canal à transmettre à la station de base en fonction d'une période de transmission d'informations d'état de canal d'un intervalle de temps de transmission général et de la période de transmission d'informations d'état de canal de l'intervalle de temps de transmission court; et la transmission des informations d'état de canal à transmettre à la station de base par l'intermédiaire d'un canal de commande de liaison montante d'un intervalle de temps de transmission court, l'intervalle de temps de transmission général étant réglé à 12 ou 14 symboles et l'intervalle de temps de transmission court étant réglé à 2, 4 ou 7 symboles.
(KO) 본 개시는 3GPP LTE/LTE-Advanced 시스템의 짧은 전송 시간 간격 프레임 구조에서 채널 상태 정보의 전송 및 수신에 대한 단말 및 기지국의 동작에 관한 것이다. 이를 위한 일 실시예로 단말이 짧은 전송 시간 간격(sTTI, short Transmission Time Interval)의 프레임 구조에서 채널 상태 정보(CSI, Channel State Information)를 전송하는 방법에 있어서, 기지국으로부터 RRC 시그널링을 통해 짧은 전송 시간 간격의 타입 정보를 수신하는 단계, 짧은 전송 시간 간격의 타입 정보에 기초하여 짧은 전송 시간 간격의 채널 상태 정보 전송 주기를 결정하는 단계, 일반 전송 시간 간격의 채널 상태 정보 전송 주기와 짧은 전송 시간 간격의 채널 상태 정보 전송 주기에 따라 기지국으로 전송할 채널 상태 정보를 결정하는 단계 및 기지국에 전송할 채널 상태 정보를 짧은 전송 시간 간격의 상향 링크 제어 채널을 통해 전송하는 단계를 포함하되, 일반 전송 시간 간격은 12개 또는 14개 심볼로 설정되고, 짧은 전송 시간 간격은 2개 또는 4개 또는 7개 심볼로 설정되는 것을 특징으로 하는 방법 및 장치를 제공한다.
