However, a TPC delay of more than one slot is required. As the TPC delay increases, the required E b /I 0 increases because the ability of fast TPC to track fading degrades. 16 shows the required average E b /I 0 for the average BER of 10−3 as a function of the TPC delay with M (signal power measurement interval in symbols for E b /I 0 measurement) as a parameter in the 32-Kbps data rate channel. A single-user case was evaluated since the interference from other powercontrolled users can be approximated well by Gaussian noise and can be combined with the background noise.

The node synchronization between the RNC and node B is used for estimating the timing differences between the RNC and node B without compensating the phase difference between the RNC and B frame number counters. Node synchronization between node B’s can be achieved via the node synchronization between the RNC and node B in order to determine internode B timing reference relations. This node synchronization is used for determining the intercell timing relationship with neighboring cell lists, which is needed for achieving fast cell search by an MS at handover.

Let BS(k ) be the temporary perching BS during intermittent reception from which the MS receives control information from the CCPCH. 11 Fast cell search algorithm in idle mode. 12 Relative transmitting timing of scrambling codes in the forward link. < N BS ), where N BS is the number of BS candidates to be searched. However, in the proposed method [15], BS(k ) informs the MS of the average (k ) relative time shift of the scrambling codes of BSj to that of BS(k ), ⌬k j (k ) ) (k ) (= ␶ (k j − ␶ ) (1 ≤ j < N BS ), where ␶ j (k ) BSj (k ) and ␶ (k ) are the time delays of and BS(k ), respectively, in addition to the scrambling codes of BSj .
