When the MS is in idle mode, the time sequence within the MS can be adjusted via the
SCH channel. However, the mobile station does not know how far it is away from the base
station. If the distance between the MS and the base station is 30km, the time sequence
of the MS will be 100μs slower than that of the base station. When the mobile phone
sends its first RACH signal, it is already 100μs later. For there is still another 100μs of
transmission delay, when the signal reaches the base station, the total delay is 200μs . It is
very possible that the signal collides with the pulse of the adjacent timeslot around the
base station. Therefore, RACH and some other channel access pulses will be shorter than
other pulses. Only after receiving the time sequence adjustment signal (TA) from the base
station, MS can send pulses of normal length. In this case, the MS needs to send signals by
200μs in advance.
