Abstract:
1. A method for use by a user equipment of a communication network system, the method comprising: measuring, by circuitry of the user equipment, a signal strength received from a target signal which is transmitted from an access network of the communication network system, at a first frequency of a reception filter of the user equipment, the first frequency corresponding to a first frequency channel number; comparing, by the circuitry, the signal strength measured with a predetermined threshold; and when the signal strength measured is below the predetermined threshold, incrementing the frequency channel number by S to a second frequency channel number which corresponds to a second frequency of the reception filter, S being an integer equal to or greater than 2, and measuring a signal strength received from a target signal which is transmitted from an access network of the communication network at the second frequency, and when the signal strength measured is not below the predetermined threshold, performing channel correlation at the first frequency for detecting whether synchronization with the target signal is achieved at the first frequency.
