Since the mode 4 UE performs resource selection based on the monitoring result, the mode 4 UE can monitor the resource occupancy of the mode 3 UE and other mode 4 UEs, thereby avoiding collision with other UEs. However, for the mode 3 UE, the base station does not know the resource selection of the mode 4 UE when performing resource allocation. Therefore, the mode 3 UE needs to monitor the resource pool and report the monitoring result to the base station so that the base station performs scheduling based on the monitoring result.
  • the base station does not know the resource selection of the mode 4 UE when performing resource allocation. Therefore, the mode 3 UE needs to monitor the resource pool and report the monitoring result to the base station so that the base station performs scheduling based on the monitoring result.

  • the mode 3 UE needs to report the monitoring result, but if the complete monitoring result is reported, the amount of reported data is very large. Since the time range of the UE can be monitored is up to 100 ms (that is, 100 subframes), the frequency domain ranges from a maximum of 25 subchannels (ie, 4 physical resource blocks (PRBs), 20MHz bandwidth), so the maximum occupancy of 2500 resource units needs to be reported. Moreover, since the monitoring result is dynamically changed, the mode 3 UE needs to report the monitoring result before each mode 3 UE is scheduled, thereby occupying more uplink channel resources, resulting in waste of uplink channel resources.

Abstract

Selon certains modes de réalisation, la présente invention concerne un procédé de rapport d'informations, un procédé d'attribution de ressources, un équipement utilisateur et une station de base. Le procédé d'attribution de ressources comprend les étapes suivantes : un équipement utilisateur (UE) détermine un premier sous-ensemble de ressources ou un second sous-ensemble de ressources selon un résultat d'écoute de ressources temps-fréquence, le premier sous-ensemble de ressources comprenant des ressources de domaine temporel et/ou des ressources de domaine fréquentiel qui peuvent être attribuées parmi les ressources temps-fréquence, et le second sous-ensemble de ressources comprenant des ressources de domaine temporel et/ou des ressources de domaine fréquentiel qui ne peuvent pas être attribuées parmi les ressources temps-fréquence ; l'UE envoie des premières informations à une station de base, les premières informations étant utilisées pour indiquer le premier sous-ensemble de ressources ou le second sous-ensemble de ressources ; la station de base détermine des ressources de domaine temporel et/ou des ressources de domaine fréquentiel attribuées à l'UE ; et la station de base envoie des sixième informations à l'UE, les sixièmes informations étant utilisées pour indiquer les ressources de domaine temporel et/ou les ressources de domaine fréquentiel attribuées à l'UE. Au moyen des modes de réalisation de la présente invention, des ressources de canal de liaison montante peuvent être sauvegardées, et des conflits entre un UE et d'autres UE peuvent être évités.
