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 communication apparatus and method for operating a communication apparatus are provided. The communication apparatus is configured to determine whether a sub-frequency band causing interference is present among sub-frequency bands included in a reception frequency band group, and to send to another communication apparatus an interference avoidance request signal which requests the other communication apparatus to transmit signals by use of remaining sub-frequency bands except the sub-frequency band causing interference, leading to simpler and more efficient interference avoidance.
