1. An electronic device at user equipment side in a wireless communication system, comprisingcircuitry, configured todetermine a link quality between the user equipment and a network side apparatus;

  • under a condition that the link quality is better than a threshold, decide to communicate with the network side apparatus directly, under a condition that the link quality is worse than a threshold, decide to communicate, via device-to-device communication, with another user equipment within proximity that acts as a central node and forwards data packet of the user equipment to the network side apparatus;

    if device-to-device communication is decided, transmit a discovery signal for device-to-device discovery and monitor a discovery response signal from the other user equipment; and

    transmit a data packet to the other user equipment based on the response signal so that the data packet is subsequently forwarded to the network side apparatus by the other user equipment, whereinthe discovery signal comprises an indication of characteristics of the data packet to be transmitted for the other user equipment determining transmission resources for the electronic device, andthe indication of characteristics of the data packet comprise a transmission reliability requirement of the data packet.
