Abstract:
1. A method of relay transmission for a mobile communication system, the mobile communication system including a base station, a first user equipment unit (UE), and a second user equipment unit (UE), the method comprising: determining whether a first transmission rate of the first UE is lower than a threshold value, and if yes, proceeding the following steps; performing a relay request confirmation procedure for the first UE and the second UE so as to confirm that the first UE is enabled to send a message via the second UE; performing a base station confirmation procedure for the first UE, the second UE, and the base station so as to confirm that the base station permits the first UE to send the message via the second UE to the base station; performing an identity authentication procedure for the first UE, the second UE, and the base station so as to establish a relay channel; performing a relay start confirmation procedure for the first UE and the second UE so as to confirm that a relay transmission procedure for the first UE and the second UE is allowed to be performed; and performing the relay transmission procedure for the first UE, the second UE, and the base station, wherein the first UE sends the message to the base station via the second UE at a relay transmission rate, which is higher than the first transmission rate.
