Abstract
A base station allocates radio resources used for device-to-device D2D communication based on location information indicating a geographical location of a user terminal located in a cell of a base station. The base station notifies the allocated radio resources to the user terminal by a unicast manner, and the user terminal uses the allocated radio resources to transmit a signal for the D2D communication.
Claims3
A method for a mobile communication system that supports a device-to-device (D2D) communication that is direct inter-terminal communication, comprising:
- transmitting location information indicating a geographical location of a user terminal located in a cell of a base station, from the user terminal to the base station;
- allocating, at the base station, radio resources to the user terminal based on the location information, wherein the radio resources are used by the user terminal to transmit a signal for the D2D communication;
- notifying the allocated radio resources to the user terminal by a unicast manner;
- receiving, at the user terminal, a unicast signal indicating the radio resources allocated by using the location information, from the base station;
- and
- using the allocated radio resources to transmit the signal for the D2D communication.
A base station for a mobile communication system that supports a device-to-device (D2D) communication that is direct inter-terminal communication, comprising:
- a controller configured to:
- acquire location information indicating geographical location of a user terminal located in a cell of the base station, from the user terminal,
- allocate radio resources to the user terminal based on the location information, wherein the radio resources are used by the user terminal to transmit a signal for the D2D communication, and
- notify the allocated radio resources to the user terminal by a unicast manner.
A user terminal for a mobile communication system that supports a device-to-device (D2D) communication that is direct inter-terminal communication, comprising:
- a controller configured to:
- transmit location information indicating a geographical location of the user terminal located in a cell of a base station, to the base station,
- receive a unicast signal indicating radio resources allocated by using the location information, from the base station, the unicast signal being specific to the user terminal, and
- use the allocated radio resources to transmit a signal for the D2D communication.
