Abstract
The invention relates to a method for allocating radio resources to a transmitting terminal for performing direct communication transmission over a direct link connection. The transmitting terminal receives a system information broadcast from the base station, which comprises information on a temporary transmission radio resource pool, indicating radio resources for performing a direct communication transmission, and comprises configuration information on the resource pool to limit the amount of time that the temporary radio resource pool is usable by the transmitting terminal.
Claims22
A method for allocating radio resources to a transmitting terminal for performing a direct communication transmission over a direct link connection to a receiving terminal in a communication system, the method comprising the following steps performed by the transmitting terminal:
- receiving from a base station a system information broadcast comprising information on
- a temporary transmission radio resource pool, indicating radio resources usable by those transmitting terminals receiving the system information broadcast for performing a direct communication transmission to a receiving terminal over a direct link connection, and
- configuration information on the temporary transmission radio resource pool, the configuration information limiting the amount of time that the temporary transmission radio resource pool is usable by the transmitting terminal.
A transmitting terminal for performing a direct communication transmission over a direct link connection to a receiving terminal in a communication system, the transmitting terminal comprising:
- a receiving section adapted to receive from a base station a system information broadcast comprising information on
- a temporary transmission radio resource pool, indicating radio resources usable by those transmitting terminals receiving the system information broadcast for performing a direct communication transmission to a receiving terminal over a direct link connection, and
- configuration information on the temporary transmission radio resource pool, the configuration information limiting the amount of time that the temporary transmission radio resource pool is usable by the transmitting terminal.
(canceled)
A transmitting terminal for performing a direct communication transmission over a direct link connection to a receiving terminal in a communication system, wherein the transmitting terminal is preconfigured with a preconfigured transmission radio resource pool, indicating radio resources usable by the transmitting terminal for performing the direct communication transmission to a receiving terminal over the direct link connection, wherein the preconfigured transmission radio resource pool is usable when the transmitting terminal is in coverage of a cell of a base station.
