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. |
