Abstract

Les modes de réalisation de la présente demande concernent un procédé, un appareil et un système de transmission d'informations. Le procédé comprend les étapes suivantes : un premier dispositif de communication détermine que des informations de localisation d'un second dispositif de communication satisfont une première condition, et le premier dispositif de communication reçoit un PSSCH planifié par des premières informations envoyées par le second dispositif de communication ; le premier dispositif de communication détermine que les informations de localisation du second dispositif de communication ne satisfont pas la première condition, et le premier dispositif de communication ne reçoit pas le PSSCH planifié par les premières informations. En d'autres termes, c'est uniquement lorsque les informations de localisation du second dispositif de communication satisfont la première condition que le premier dispositif de communication reçoit le PSSCH planifié par les premières informations envoyées par le second dispositif de communication, de sorte que la consommation de puissance du premier dispositif de communication pour traiter des informations puisse être réduite, et le but d'économiser la consommation de puissance est réalisé.
