<p>Provided are a communication system, a base station, user equipment and a signalling transmission method. The system includes: a first base station and a second base station. User data transmission exists between the first base station and UE, and the first base station performs control signalling interaction with the UE via a first signalling radio bearer, and the second base station performs control signalling interaction with the UE via an SRB0, an SRBl or an SRB2, wherein the first signalling radio bearer is different from the SRB0, SRBl and SRB2. The technical solution of the present invention can solve the configuration problem of the radio resource of an air interface connection between an enhanced layer base station and UE.</p> |
