AI Technical Summary
Technical Problem
NR sidelink and LTE sidelink cannot detect each other's resource usage, leading to difficulty in sharing resources between terminals using different Radio Access Technologies (RATs).
Method used
A mobile station is configured to receive sidelink control information in different RATs, determine resources, and exclude overlapping candidates to perform sidelink transmission using selected resources.
Benefits of technology
Resources can be shared between terminals using different RATs, enabling efficient direct communication.

Abstract
This terminal includes: a first communication unit that transmits / receives with a first Radio Access Technology (RAT); a first control unit that controls the communications with the first RAT; a second communication unit that transmits / receives with a second RAT; and a second control unit that controls the communications with the second RAT. The first communication unit receives information about a first resource reservation from another terminal. The second communication unit receives information about a second resource reservation from the other terminal. The second control unit notifies the first control unit of the information about the second resource reservation. The first control unit excludes the resource from resource candidates that can be used with the first RAT, on the basis of the information about the first resource reservation and the information about the second resource reservation, and then determines a resource to use for transmission. The first communication unit uses the determined resource to execute transmission to the other terminal.
