Abstract
(EN)
The present application relates to the field of wireless communication technologies, and provides a channel sounding method, a network side device, and a terminal. The method discloses: when a first terminal needs to communicate with a second terminal, sending a resource scheduling request to a network side device; the resource scheduling request being used for requesting the network side device to allocate transmission resources for channel sounding between the first terminal and the second terminal; the resource scheduling request carrying the information of the second terminal; the first terminal receiving a sounding reference signal sent by the second terminal, and acquiring the channel information for communication between the first terminal and the second terminal. The solution provided by the present embodiments can rapidly and efficiently perform channel sounding between terminals, thereby improving the communication efficiency between terminals.

La présente invention appartient au domaine des technologies de communication sans fil, et concerne un procédé de sondage de canal, un dispositif côté réseau, et un terminal. Le procédé comprend les étapes suivantes : lorsqu'un premier terminal doit communiquer avec un second terminal, envoyer une demande de programmation de ressources à un dispositif côté réseau, la demande de programmation de ressources étant utilisée pour demander au dispositif côté réseau d'attribuer des ressources de transmission pour un sondage de canal entre le premier terminal et le second terminal, la demande de programmation de ressource contenant les informations du second terminal ; le premier terminal reçoit un signal de référence de sondage envoyé par le second terminal, et acquiert les informations de canal pour une communication entre le premier terminal et le second terminal. La solution fournie par les présents modes de réalisation peut exécuter un sondage de canal entre terminaux de manière rapide et efficace, ce qui permet d'améliorer l'efficacité de communication entre des terminaux.
