<p>A method for performing hybrid automatic repeat request (HARQ), a base station (BS), and a mobile device are provided. In the method, a wireless resource is allocated by the BS, and whether to perform a device-to-device (D2D) communication is determined. When the D2D communication is performed, a first resource allocation message is transmitted by the BS to a first mobile device and a second mobile device, and the first mobile device, working as a transmitter, transmits a data packet to the second mobile device, working as a receiver, according to the first resource allocation message. A HARQ feedback packet is received by the BS from the second mobile device to determine whether the data packet is successfully transmitted. When the HARQ feedback packet is a negative acknowledgement (NACK), the BS retains the original wireless resource or transmits a second resource allocation message to the first and the second mobile devices.</p> |
