Abstract
The present invention is designed so that adequate mutual detection is made possible in non-collision-type D2D discovery during inter-terminal direct communication. A user terminal can execute inter-terminal direct communication, and has a receiving section that receives initial allocation location information of a resource for transmitting a discovery signal for use in inter-terminal direct communication, and a control section that switches the location of the resource to transmit the discovery signal, per period, in accordance with a pre-rule.
Claims11
A user terminal that can execute inter-terminal direct communication, comprising:
- a receiving section that receives initial allocation location information of a resource for transmitting a discovery signal for use in the inter-terminal direct communication;
- and
- a control section that switches a location of the resource to transmit the discovery signal, per period, in accordance with a pre-rule.
A radio base station that can communicate with a user terminal that can execute inter-terminal direct communication, the radio base station comprising a transmitting section that transmits, to the user terminal, initial allocation location information of a resource for transmitting a discovery signal for use in the inter-terminal direct communication, and also transmits a resource index that was used in initial allocation, and resource size information, to a nearby radio base station.
A radio communication method for a user terminal that can execute inter-terminal direct communication, the radio communication method comprising the steps of:
- receiving initial allocation location information of a resource for transmitting a discovery signal for use in the inter-terminal direct communication;
- and
- switching a location of the resource to transmit the discovery signal, per period, in accordance with a pre-rule.
