摘要： A wireless communication system includes an apparatus capable of detecting whether a cell coverage is downscaled. The wireless communication system receives information used for communication between an evolved NodeB (eNodeB) and a User Equipment (UE) from the eNodeB. The UE performs at least one of pilot signal power checking for checking if a pilot signal power falls within a first reference range, DownLink (DL) Signal-to-Interference plus Noise Ratio (SINR) checking for checking if an SINR of a DL traffic channel falls within a second reference range, and UpLink (UL) SINR checking for checking if an SINR of an UL traffic channel falls within a third reference range using the received information. The UE also detects whether a cell coverage of a cell to which the eNodeB and the UE belongs is downscaled based on a checking result.

摘要： A method and an apparatus select optimized Frequency Allocation (FA) in a mobile communication system that includes mobile base stations. A first control information is received from neighbor base stations. System capacities of the respective neighbor base stations are determined based on the first control information. The FA that maximizes a sum of the system capabilities of the respective neighbor base stations is selected. Therefore, the method has an advantage of securing maximum capacity by adaptively setting FA with consideration of radio environments of neighbor base stations during network entry of a new mobile base station or during an operation of a mobile base station.
