Transmission method for auxiliary carrier pairing information, node b and system for implementing transmission

The present invention discloses a transmission method for auxiliary carrier pairing information, a node B and a system for implementing the transmission. The transmission method includes that: during the process of controlling a terminal which uses multi-carrier high speed packet access technique, the node B to which the terminal belongs sets the pairing information of uplink auxiliary carriers and downlink auxiliary carriers of auxiliary service enhanced dedicated channel cells for the terminal, and transmits the information to a wireless network control entity through control signaling transmitted by an interconnection of type B interface. Basing on the interconnection of type B/interconnection of radio network controller interface, the present invention can implement the flexible configuration for the uplink auxiliary carriers and the downlink auxiliary carriers through signaling.
