Abstract: A method of allocating resources in a mobile telecommunications system, the resources being for a relay node to operate as a terminal-to-terminal relay for a device-to-device communication between a first terminal and a second terminal. The method includes: allocating first resources for the first terminal to communicate via the relay node for the device-to-device communication; allocating second resources for the second terminal to communicate via the relay node for the device-to-device communication; notifying the first terminal of the allocated first resources; notifying the second terminal of the allocated second resources; and the first and second terminals exchanging messages for the device-to-device communication via the relay node and using the first and second resources, respectively.

Abstract: A wireless communications system and a method for performing wireless communication in a wireless communications system. The wireless communications system includes: a first base station node; a second base station node; and a wireless communications apparatus, performing communication with the first base station node and the second base station node. The first base station node and the second base station node perform scheduling coordination, to reduce a probability that the wireless communications apparatus sends an uplink signal to the first base station node and the second base station node simultaneously. The system and method can reduce a probability that a wireless communications apparatus sends an uplink signal to a first base station node and a second base station node simultaneously, thereby effectively ensuring uplink/downlink transmission performance.
