AI Technical Summary
Technical Problem
In direct terminal-to-terminal communication, the operation of autonomous resource selection lacks specification based on priority, particularly in power-saving enhancements for NR sidelink communication.
Method used
A terminal is equipped with a control unit that determines candidate resources based on sensing results and selects a resource for transmission, considering priority-related terminal-to-terminal cooperation information and data priority.
Benefits of technology
Enables operations related to autonomous resource selection based on priority in direct terminal-to-terminal communication, enhancing power-saving capabilities.

Abstract
To execute operations related to autonomous resource selection on the basis of a priority in inter-terminal direct communication.SOLUTION: A terminal comprises: a control unit which determines a first resource to be sensed, identifies candidate resources on the basis of a sensing result of the first resource, and determines a set of available resources; and a transmission unit which selects a second resource to be used for transmission from the resource set and transmits data to another terminal using the second resource. The control unit determines processing related to transmission of data transmitted by the own device on the basis of a priority associated with a request of inter-terminal coordination information and a priority associated with data transmitted by the own device.SELECTED DRAWING: Figure 26
