When a PD detects another PAC network, it decides whether it will stay in the network it currently belongs to or move to the detected PAC network using the relative timing between the two PAC networks as follows: In Figure 32, if T1 is smaller than T2, PDs in network 2 move to network 1, and PDs in network 1 stay in network 1. In Figure 32, if T1 is greater than T1, PDs in network 1 move to network 2, and PDs in network 2 stay in network 2. Re-synchronization procedure If the condition for Re-synchronization is met, a PD enters Re-synchronization procedure. The Re-synchronization procedure is identical to Initial synchronization procedure, except that a PD uses its own timing as an initial timing. The condition for Re-synchronization is defined in 5.3.2. A PD scans for the existing synchronization signals for a TBD scanning period. If a synchronized condition is met, it makes a transition to Maintaining synchronization period. The synchronized condition is determined from the fact whether a synchronization signal or multiple synchronization signals with the same timing is/are detected during the scanning period. If the synchronized condition is not met, the PD adjusts its own reference timing based on detected synchronization signals.
