Abstract: A radio communication system includes a macrocell base station which can communicate with radio terminals using any of a plurality of carrier frequencies, and a femtocell base station provided in a macrocell in which the macrocell base station can communicate with the radio terminals, and capable of communicating with the radio terminals in an access limited mode in which only a specific radio terminal can access or a hybrid mode in which an access is not limited only to the specific radio terminal using any of the plurality of carrier frequencies. The femtocell base station includes: a measuring part which measures an uplink total received power from a radio terminal; a detecting part which detects a visitor macrocell radio terminal located in a vicinity of the femtocell base station operated by the access limited mode in accordance with the uplink total received power or an uplink interference signal power which can be derived from the uplink received power; and a control part which switches the femtocell base station from the access limited mode to the hybrid mode when the detecting part detects the visitor macrocell radio terminal. Accordingly, it is possible to improve the throughput for the visitor macrocell user.

Abstract translation: 无线通信系统包括可以使用多个载波频率中的任一个与无线终端进行通信的宏小区基站，以及设置在宏小区中的蜂窝基站，其中，所述宏小区基站能够与无线终端进行通信，能够进行通信 其中无线电终端处于只有特定无线电终端可以访问的访问限制模式，或者混合模式，其中访问不仅限于使用多个载波频率中的任何一个的特定无线电终端。 毫微微小区基站包括：测量部分，其测量来自无线终端的上行链路总接收功率; 检测部，其根据所述上行链路总接收功率或上行接收功率导出的上行干扰信号功率，检测位于所述接入限制模式下操作的所述毫微微小区基站附近的访问宏小区无线终端; 以及控制部，当所述检测部检测到所述访问者宏小区无线终端时，将所述毫微微小区基站从所述接入限制模式切换到所述混合模式。 因此，可以提高访问者宏小区用户的吞吐量。
