Title (EN) CHANNEL DIRECTION INFORMATION ACQUISITION METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF D'ACQUISITION D'INFORMATIONS DE DIRECTION DE CANAL
Abstract:
(EN) The present invention provides a channel direction information acquisition method. In a terminal, the terminal transmits, to another terminal, a first signal for a first resource, based on beamforming regarding a first angle, transmits, to another terminal, a second signal for a second resource based on beamforming regarding a second angle, wherein a first beam for the first signal and a second beam for the second signal are overlapped, and receives, from the another terminal, information for a channel direction. The present invention further provides a channel direction information acquisition method applying to a receiving terminal, a corresponding transmitting terminal device and a corresponding receiving terminal device. According to the technical solution provided by the present invention, reliable channel direction information can be provided.
(FR) La présente invention concerne un appareil et un procédé d’acquisition d'informations de direction de canal. Dans un terminal, le terminal transmet, à un autre terminal, un premier signal destiné à une première ressource, en fonction de la formation de faisceau concernant un premier angle, transmet, à un autre terminal, un second signal destiné à une seconde ressource en fonction de la formation de faisceau concernant un second angle, un premier faisceau destiné au premier signal et un second faisceau destiné au second signal se chevauchant et recevant en provenance de l'autre terminal, des informations destinées à une direction de canal. La présente invention concerne en outre un procédé d'acquisition d'informations de direction de canal à appliquer à un terminal de réception, un dispositif terminal de transmission correspondant et un dispositif terminal de réception correspondant. Selon la solution technique fournie par la présente invention, des informations de direction de canal fiables peuvent être fournies.
