Patent ID: 8670424

Claim:
A method for detecting whether a cell coverage is downscaled in a wireless communication system, the method comprising: receiving information used for communication between an evolved NodeB (eNodeB) and a User Equipment (UE) from the eNodeB, the information being acquired by the eNodeB and the UE; performing, by using the received information, 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; and detecting whether a cell coverage of a cell to which the eNodeB and the UE belongs is downscaled, based on a checking result according to at least one of the pilot signal power checking, the DL SINR checking, the UL SINR checking.
