A method for establishing a radio bearer, RB, between User Equipments, the method comprising the steps of: determining, by a base station, an RB of a beneficial user equipment, UE, performing cooperative communication and a support UE corresponding to the RB of the beneficial UE; sending, by the base station, cooperative RB configuration information of the beneficial UE to the beneficial UE for the beneficial UE to establish a cooperative RB, and sending cooperative RB configuration information of the support UE to the support UE for the support UE to establish the cooperative RB; and performing, by the base station, cooperative communication with the beneficial UE and the support UE; wherein the determining, by a base station, an RB of a beneficial UE performing cooperative communication and a support UE corresponding to the RB of the beneficial UE comprises the further steps of: receiving, by the base station, a radio resource control, RRC, message which carries a first pairing identifier of the beneficial UE and a non-access stratum, NAS, message packet for requesting establishment of a bearer and is sent by the beneficial UE; returning, by the base station, RB configuration information of the beneficial UE to the beneficial UE according to the received RRC message sent by the beneficial UE for establishing a corresponding RB; after receiving an RRC message or a medium access control layer control element, MAC CE, that carries a second pairing identifier of at least one UE and is sent by the at least one UE, reserving, by the base station, an RRC connection of the at least one UE, and storing the second pairing identifier of the at least one UE; and determining, by the base station, that the UE with the second pairing identifier being consistent with the first pairing identifier of the beneficial UE as the support UE corresponding to the RB of the beneficial UE. determining, by a base station, an RB of a beneficial user equipment, UE, performing cooperative communication and a support UE corresponding to the RB of the beneficial UE; sending, by the base station, cooperative RB configuration information of the beneficial UE to the beneficial UE for the beneficial UE to establish a cooperative RB, and sending cooperative RB configuration information of the support UE to the support UE for the support UE to establish the cooperative RB; and performing, by the base station, cooperative communication with the beneficial UE and the support UE; wherein the determining, by a base station, an RB of a beneficial UE performing cooperative communication and a support UE corresponding to the RB of the beneficial UE comprises the further steps of: receiving, by the base station, a radio resource control, RRC, message which carries a first pairing identifier of the beneficial UE and a non-access stratum, NAS, message packet for requesting establishment of a bearer and is sent by the beneficial UE; returning, by the base station, RB configuration information of the beneficial UE to the beneficial UE according to the received RRC message sent by the beneficial UE for establishing a corresponding RB; after receiving an RRC message or a medium access control layer control element, MAC CE, that carries a second pairing identifier of at least one UE and is sent by the at least one UE, reserving, by the base station, an RRC connection of the at least one UE, and storing the second pairing identifier of the at least one UE; and determining, by the base station, that the UE with the second pairing identifier being consistent with the first pairing identifier of the beneficial UE as the support UE corresponding to the RB of the beneficial UE.
