    Abstract: The present invention relates to a method and apparatus for managing radio resources in a multi-carrier and heterogeneous network-integrated radio access environment. A method of managing radio resources in a BS supporting multiple carriers includes sending an RRC connection reconfiguration message, including measurement control information, to UE, receiving a measurement report, including a measurement result for an HetNet RAT cell, from the UE, determining to configure HetNet RAT bearer connection with the UE based on the measurement report, sending an RRC connection reconfiguration message, requesting to configure the HetNet RAT bearer connection, to the UE, and sending some of or the entire traffic for the UE, to the UE through the HetNet RAT bearer. If overload or interference occurs in a serving cell, some of or the entire traffic is transmitted through a cell based on HetNet RAT, if necessary. Accordingly, load balancing or interference coordination can be achieved.

    Abstract translation: 本发明涉及一种用于管理多载波和异构网络集成无线电接入环境中的无线电资源的方法和装置。 一种管理支持多载波的BS中的无线电资源的方法包括向UE发送包括测量控制信息的RRC连接重配置消息，从UE接收包括HetNet RAT小区的测量结果的测量报告，确定配置 基于测量报告与UE的HetNet RAT承载连接，向UE发送请求配置HetNet RAT承载连接的RRC连接重配置消息，并向UE发送UE的一些或整个业务，通过 HetNet RAT承载。 如果在服务小区中发生过载或干扰，则必要时，通过基于HetNet RAT的小区传送一些或整个业务。 因此，可以实现负载平衡或干扰协调。
