Title
(EN) SIDELINK COMMUNICATION METHOD AND APPARATUS
(FR) PROCÉDÉ ET APPAREIL DE COMMUNICATION DE LIAISON LATÉRALE
(ZH) 一种侧行链路通信方法及装置
Abstract
(EN) A sidelink communication method and apparatus, capable of being applied to the field of device-to-device (D2D) or Internet of vehicles, and the like. The method comprises: when a first terminal and a second terminal perform data transmission by means of a sidelink, an error occurs when a network device receives the acknowledgement information of the sidelink transmitted by the second terminal, and the signal quality of an uplink between the first terminal and the network device is greater than or equal to a first signal quality threshold, the first terminal receives first information from the network device, wherein the first information is used for indicating the first terminal to transmit the acknowledgement information of the sidelink to the network device; and the first terminal transmits the acknowledgement information of the sidelink to the network device. The network device can flexibly configure the terminal that transmits the acknowledgement information of the sidelink to the network device, and ensures the normal communication of the sidelink.
(FR) Procédé et appareil de communication de liaison latérale, pouvant s'appliquer au domaine de dispositif à dispositif (D2D) ou à l'Internet des véhicules, et analogues. Le procédé comprend les étapes suivantes : lorsqu'un premier terminal et un second terminal effectuent une transmission de données au moyen d'une liaison latérale, une erreur se produit lorsqu'un dispositif de réseau reçoit les informations d'accusé de réception de la liaison latérale transmises par le second terminal, et la qualité de signal d'une liaison montante entre le premier terminal et le dispositif de réseau est supérieure ou égale à un premier seuil de qualité de signal ; le premier terminal reçoit des premières informations à partir du dispositif de réseau, ces premières informations étant utilisées pour indiquer au premier terminal de transmettre les informations d'accusé de réception de la liaison latérale au dispositif de réseau ; et le premier terminal transmet les informations d'accusé de réception de la liaison latérale au dispositif de réseau. Le dispositif de réseau peut configurer de manière flexible le terminal qui transmet les informations d'accusé de réception de la liaison latérale au dispositif de réseau, et assure la communication normale de la liaison latérale.
(ZH) 一种侧行链路通信方法及装置,可以应用于设备到设备(device-to-device,D2D)或车联网(vehicle-to-everything)等领域。该方法包括:在第一终端与第二终端通过侧行链路进行数据传输时,当网络设备接收第二终端发送的侧行链路的应答信息发生错误的情况,且第一终端与网络设备之间的上行链路信号质量大于或等于第一信号质量阈值时,第一终端接收来自网络设备的第一信息,第一信息用于指示第一终端向网络设备发送侧行链路的应答信息;第一终端向网络设备发送侧行链路的应答信息。网络设备可以灵活地配置向网络设备发送侧行链路的应答信息的终端,保证侧行链路的正常通信。
