Abstract:
1. An apparatus for generating reference timings for channel signal transmission/reception in a system where each of at least two Node Bs transmits a first channel signal for providing a reference timing and a second channel signal different from the first channel signal and a user equipment (UE) having a plurality of fingers for demodulating the first channel signal, the apparatus comprising: a first timing generator for receiving a system frame number (SFN) of a reference Node B having a communication link established with the UE, selecting a first channel frame boundary (FB) timing output from a reference finger that earliest demodulates the first channel signal from the reference Node B among the FB timings of the first channel signals from the reference Node B demodulated in the fingers, and generating an SFN reference timing based on the SFN of the reference Node B and the first channel FB timing of the reference finger; a second timing generator for generating a second channel FB timing to demodulate the second channel signal from the reference Node B by giving a predetermined timing offset to the first channel FB timing of the reference finger; and a third timing generator for receiving the first channel FB timing of the reference finger and the second channel FB timing, and generating an uplink channel FB timing having a predetermined offset from the second channel FB timing.
