Abstract
There is provided an apparatus including a receiver configured to receive a signal from a transmitting terminal via a direct device-to-device communication connection, and to receive a cellular reference signal from a cellular network; a processor configured to measure a time difference between the received signal and the cellular reference signal; and a transmitter configured to transmit the result of the measured time difference to the transmitting terminal for adjusting device-to-device transmission timing of the transmitting terminal.
Claims24
An apparatus comprising:
- a receiver configured to receive a signal from a transmitting terminal via a direct device-to-device communication connection, and to receive a cellular reference signal from a cellular network;
- a processor configured to measure a time difference between the received signal and the cellular reference signal;
- and
- a transmitter configured to transmit the result of the measured time difference to the transmitting terminal for adjusting device-to-device transmission timing of the transmitting terminal.
An apparatus comprising:
- a transmitter configured to transmit a signal to a receiving terminal via a direct device-to-device communication connection for enabling the receiving terminal to measure a time difference between the transmitted signal and a cellular reference signal of a cellular network;
- a receiver configured to receive the result of the measured time difference from the receiving terminal;
- and
- a processor configured to adjust device-to-device transmission timing of the apparatus on the basis of the received result of the measured time difference.
A method comprising:
- receiving a signal from a transmitting terminal via a direct device-to-device communication connection, and receiving a cellular reference signal from a cellular network;
- measuring a time difference between the received signal and the cellular reference signal;
- and
- transmitting the result of the measured time difference to the transmitting terminal for adjusting device-to-device transmission timing of the transmitting terminal.
A method comprising:
- transmitting a signal to a receiving terminal via a direct device-to-device communication connection for enabling the receiving terminal to measure a time difference between the transmitted signal and a cellular reference signal of a cellular network;
- receiving the result of the measured time difference from the receiving terminal;
- and
- adjusting device-to-device transmission timing of the apparatus on the basis of the received result of the measured time difference.
An article of manufacture, comprising a computer readable medium and embodying program instructions thereon, executable by a computer operably coupled to a memory and, when executed by the computer, carry out the functions of:
- receiving a signal from a transmitting terminal via a direct device-to-device communication connection, and receiving a cellular reference signal from a cellular network;
- measuring a time difference between the received signal and the cellular reference signal;
- and
- transmitting the result of the measured time difference to the transmitting terminal for adjusting device-to-device transmission timing of the transmitting terminal.
An apparatus comprising:
- a processor configured to perform a pairing process of a first terminal and a second terminal for a direct device-to-device communication connection;
- a receiver configured to receive from the first terminal a result of a measured time difference between a signal from the second terminal and a cellular reference signal from a cellular network;
- and
- a transmitter configured to transmit the result of the measured time difference to the second terminal for adjusting device-to-device transmission timing of the second terminal.
