Abstract:
There is provided a method for determining frequency correction and time slot boundary detection for synchronization in a wireless device. A plurality of cell broadcast frequencies is acquired. A subgroup of cell broadcast frequencies is determined from the received plurality of cell broadcast frequencies. Frequency and time slot information in the subgroup is recovered by tuning a local oscillator to a center frequency of the subgroup. Individual frequencies are extracted from the recovered frequency information. The individual frequencies are provided to a frequency correction detector. A corresponding wireless device, computer program and computer program product are also provided.
