摘要： A method of controlling femtocell interference considering a macrocell is provided. The method of controlling the interference includes a method of setting transmission power of the femtocell and methods of avoiding the interference of the femtocell. The methods of avoiding the interference include a PRB rotation method, a PRB transmission power restriction method, a hybrid method and a UB rotation method. The method of setting the transmission power and the methods of avoiding the interference may be implemented independently or implemented in combination with each other. Hence, according to the present invention, the femtocell itself can control the interference without affecting an interface of an existing macrocell base station and without signaling through the interface with the macrocell.

摘要： The present invention relates to a vertical handoff method. According to the present invention, a serving network of a mobile station is determined. Herein, the mobile station that can access a first network having relatively wide service coverage and a second network having relatively narrow service coverage in an area where service coverages of heterogeneous networks are overlapped. When accessing the serving network of the first network, it is determined whether a received signal strength received from the second network is greater than a first threshold value. In addition, a first vertical handoff is decided by using a result of prediction of a transition pattern of the received signal strength that is greater than the first threshold value. When the serving network is the second network, it is determined whether the received signal strength received from the second network is less than a second threshold value. By using a result of prediction of a transition pattern of the received signal strength that is less than the second threshold value, a second vertical handoff is decided. Herein, the first threshold value is greater than the second threshold value.

摘要： There are provided a control channel managing apparatus of a base station, a control channel searching apparatus of a user equipment (UE) and a control channel allocating method in a mobile communication system. When an aggregation level is high and a plurality of UEs having the same starting address of a control channel search space are scheduled in a corresponding subframe, control information with respect to conflicting UEs which have lower priorities in terms of allocation of control information can be transmitted through the conflicting UE space. Hence, more control information can be transmitted and the number of available UEs corresponding to the control information increases, and thus an improvement in the performance of the entire network can be achieved.
