Abstract:
1. A method of performing cell measurements in a telecommunications system, the method comprising the steps of: receiving a signal by a user equipment (UE) operating within the telecommunications system and served by a serving cell, and within range of at least one neighbor (NB) cell based on a NB cell list or detected NB cell; storing the received signal in a buffer; determining a first portion of the signal related to the serving cell and a second portion related to at least one of the NB cells; decoding the first portion of the signal by a Fast Fourier Transform (FFT); estimating a signal strength of the first portion of the signal by a measurement unit coupled to the FFT; determining if any NB cell signal by the UE in the second portion of the signal is in approximate time synchronization with the serving cell; upon determining that a NB cell signal of the second portion of the signal is in approximate time synchronization with a serving cell of the UE, estimating a signal strength of the NB cell signal in approximate time synchronization by the measurement unit; determining if sufficient time remains to process NB cell signals of the second portion of the signal that are not in approximate time synchronization; and upon determining that sufficient time remains, to process NB cell signals of the second portion of the signal that are not in approximate time synchronization, playing back the second portion of the signal, decoding the second portion using the FFT and estimating a signal strength of any NB cell signals of the second portion of the received signal that are not in approximate time synchronization.
