A wireless mesh network includes heterogeneous types of nodes, including continuously-powered nodes and battery-powered nodes. The battery-powered nodes may reside in a sleeping state most of the time to conserve power. The various nodes in the network may communicate with one another by transmitting and receiving at scheduled times and on scheduled frequencies. The battery-powered nodes may become active during the scheduled transmit and receive times. Network management nodes may facilitate network formation by transmitting information that reflects the scheduled transmit and receive times across the network. Based on this data, the continuously-powered nodes and battery-powered nodes may establish communication links with one another.

The invention discloses a pretreating method, a device and a system in frequency domain resource scheduling. The method comprises the following steps of: dividing the whole bandwidth of a channel between a network side and a terminal into at least two sub-bands, and receiving Sounding signals sent by the terminal on a preset bandwidth of each sub-band; determining the channel characteristic of each sub-band according to the Sounding signals; and selecting one or more sub-bands from the at least two sub-bands according to the channel characteristic to schedule frequency domain resource for the terminal in the bandwidth range of the one or more sub-bands.

The timing resuming device and method with protecting function uses for one CD (Compact Disc) reading system. When the timing character is good, it counts by frequency estimator and store proper frequency estimated value as scheduled frequency estimated value and detect whether the CD reading system read the CD area with vice by vice detector. If it finds vice, store the scheduled frequency estimated value as basement of frequency locked and phase locked to produce referenced timing. When it gets right, restart natural frequency locked mechanism to lock input signal in shorter time. It can greatly reduce the dropping of readable data for frequency doffed and break the action about normally tracking frequency of frequency locked mechanism.
