APPARATUS AND METHOD FOR PROXIMITY-BASED SERVICE COMMUNICATION
First Claim
1. A radio terminal apparatus comprising:
- at least one radio transceiver; and
at least one processor coupled to the at least one radio transceiver, whereinthe at least one processor is configured to transmit resource information to a radio access network, the resource information indicating a first radio resource to be used for sidelink communication, an effective period or effective number of times of the first radio resource, or both the first radio resource and the effective period or effective number of times, andthe sidelink communication comprises at least one of direct discovery and direct communication performed between the radio terminal apparatus and another radio terminal using the at least one radio transceiver.

Abstract
A radio terminal apparatus (1) transmits, to a radio access network (3), resource information indicating a first radio resource to be used for sidelink communication (103), an effective period or effective number of times of the first radio resource, or both the first radio resource and the effective period or effective number of times. The sidelink communication (103) includes at least one of direct discovery and direct communication performed between the radio terminal apparatus (1) and another radio terminal (2). It is thus, for example, possible to contribute to avoidance of conflict between a radio resource for a sidelink communication and a radio resource for an intra-cell uplink transmission, intra-cell downlink transmission, or another sidelink communication.
