A method for setting resources for direct communication between terminals based on congestion control in a wireless communication system and a device for that purpose.

摘要

PROBLEM TO BE SOLVED: To provide a method of transmission using a side link data channel by a terminal in a wireless communication system. A plurality of transmissions using a plurality of resources include a stage of performing a plurality of transmissions on a side link data channel using a plurality of resources, and the plurality of transmissions using the plurality of resources are among a plurality of priority levels for the plurality of transmissions. For each priority level of, for transmission with a priority below the priority level, the total resource usage for transmission is limited to below the threshold corresponding to the priority level, and the threshold is sidelink. It is performed so as to satisfy the condition that it is related to the maximum use of resources for transmission at the priority level on the data channel. [Selection diagram] FIG. 9
