Abstract
(EN)
Embodiments of the present application provide a signal transmission method and a communication device. A network device, upon finding that the success rate of uplink-signal transmission is low, determines a target transmission mode, and causes the target transmission mode to be carried in first instruction information and transmits the same to a terminal device, such that the terminal device transmits a signal to the network device according to the target transmission mode. In the present process, the network device controls the transmission mode of the terminal device, that is, the network device determines a target transmission mode on the basis of a network load, so as to effectively prevent the terminal device from using an EDT mode or a first random access mode excessively; as a result, the probability of collisions between the EDT and first random access modes is reduced, thereby improving the success rate of grant-free transmission of uplink signals performed by the terminal device when in an idle state.

Selon des modes de réalisation, la présente invention concerne un procédé de transmission de signaux et un dispositif de communication. Un dispositif réseau, après avoir constaté que le taux de réussite de la transmission de signaux de liaison montante est faible, détermine un mode de transmission cible, et amène le mode de transmission cible à être transporté dans des premières informations d'instruction qu'il transmet à un dispositif terminal, de telle sorte que le dispositif terminal transmet un signal au dispositif réseau selon le mode de transmission cible. Dans le présent procédé, le dispositif réseau commande le mode de transmission du dispositif terminal, c'est-à-dire que le dispositif réseau détermine un mode de transmission cible sur la base de la charge réseau, de façon à empêcher efficacement le dispositif terminal d'utiliser un mode EDT ou un premier mode d'accès aléatoire de manière excessive ; en conséquence, la probabilité de télescopage entre l'EDT et les premiers modes d'accès aléatoire est réduite, ce qui permet d'améliorer le taux de réussite de la transmission sans autorisation des signaux de liaison montante mise en œuvre par le dispositif terminal à l'état de veille.

本申请实施例提供一种信号传输方法及通信装置,当网络设备发现上行信号的成功率低时,确定出目标传输方式,并将目标传输方式携带在第一指示信息中发送给终端设备,使得终端设备根据目标传输方式向网络设备发送信号。该过程中,通过网络设备控制终端设备的传输方式,即网络设备根据网络负载确定出目标传输模式,可以有效减少终端设备集中在EDT方式或第一随机接入方式,即减小了EDT方式和第一随机接入方式的碰撞概率,实现提高空闲态的终端设备通过免调度方式发送上行信号的成功率的目的。
