  • receiving, by an access network device, downlink data belonging to a first user equipment (UE);

    adding, in response to the identifying the second UE as the potential supporting UE, the pairing identifier associated with the first UE, an identifier of the second UE and the information regarding the channel quality between the first UE and the second UE to the support list of the first UE;

    establishing, in response to, and after, the determining that each supporting UE in the support list of the first UE cannot serve as the current supporting UE of the downlink data, and further in response to the adding the pairing identifier associated with the first UE to the support list of the first UE, a cooperative communication relationship between the first UE and the second UE by setting the second UE as the current supporting UE of the first UE;
