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

A NodeB for transmitting pairing information of auxiliary carriers comprising a pairing information setting module and a pairing information transmitting module, wherein

• the pairing information setting module is configured to set pairing information of an uplink auxiliary carrier and a downlink auxiliary carrier of an auxiliary service enhanced dedicated channel cell for a terminal during the process of controlling the terminal which uses a multi-carrier high-speed packet access technique, and
• the pairing information transmitting module is configured to transmit the pairing information set by the pairing information setting module to a radio network control entity through control signaling transmitted via an IUB interface.
