摘要： Methods and apparatus related to control channels in a wireless communications system are described. Different white space bands may be available at different locations. A wireless terminal monitors control information from multiple potentially available communications channels. Control time slots corresponding to some different channels are intentionally time offset from one another. Some embodiments implement predetermined control slot timing synchronized with respect to an external timing source. In other embodiments, a wireless terminal selects a control time slot on a new channel as a function of control slot timing on channels already in use. A wireless terminal selects one of a plurality of communications channels for use in communicating information and determines a position of a control time slot to be used on the selected communications channels. The wireless terminal uses the control time slot on the selected communications channel to transmit and receive control information.

摘要： A decentralized approach to peer discovery channel selection is used in some embodiments. In some such embodiments, a mobile wireless terminal supporting a peer to peer signaling protocol, independently determines what channels to use for peer discovery without a central controller indicating the channel or channels to be used. Assuming channels are of a suitable quality, the channels having the best quality need not be identified, with channel selection being made on a predetermined channel ordering basis from those with suitable quality. Different wireless communications devices in the system use the same peer discovery channel selection process making it likely that the same channel or channels will tend to be picked to be used for peer discovery. Other embodiments are directed to implementing a centralized approach to peer discovery channel selection in which a central controller or base station selects channels to be used for peer discovery signaling.
