摘要： Methods and apparatus for determining band availability and/or allocating one or more frequency bands to a communications device for wireless communications are described. In different locations and/or at different times different frequency bands, e.g., band corresponding to unused TV channels, may be available for allocation. Various described methods and apparatus are well suited for supporting local peer to peer networks in an environment in which a plurality of different technologies are supported. A centralized control device determines and allocates a frequency band to a wireless terminal for use at a given location and at a given time, e.g., for peer to peer communications using a particular technology supported by the wireless terminal. The centralized control device uses database information and information received from a plurality of wireless terminals in making frequency band allocation decisions, performing load balancing, and/or performing interference management.

摘要： Methods and apparatus supporting load balancing in a wireless communications system implementing decentralized control are described. Different channels, e.g., unused TV channels, are available in different locations for use for communications. Various communications technologies, e.g., WiFi, 3G Blue-Tooth, etc., may be supported by a communications device and may be allowed to be used on the available channels. A wireless communications device evaluates its current local environment, e.g., estimating potential rates that it may use and/or estimating latency, for each of a plurality of available alternative channel/technology combinations. The wireless communications device selects a channel and technology combination to use as a function of its estimates. The wireless communications device uses its selected channel and technology combination for communications, e.g., for peer to peer communications including direct peer to peer traffic signaling as part of a local peer to peer network.

摘要： Various embodiments relate to using available spectrum for peer to peer communications and for selecting which of several possibly available channels should be used. Various methods and apparatus are well suited to peer to peer networks in which channel usage decisions are made in a decentralized manner. A wireless terminal generates a list of potential available channels to be used for peer to peer communications, e.g., based on FCC information and/or local sensing. Channels are filled in accordance with a predetermined channel ordering. A wireless terminal migrates between the channels in accordance with changes in the number of peer devices using a channel. The network, in a distributed manner, changes the number of channels in use at a location in response to changes in numbers of active peer devices at a location.

摘要： Methods and apparatus well suited for supporting communications over different ranges in, for example, a peer to peer wireless communications system, are described. In the peer to peer network at least some of the types of signals, e.g., peer discovery signals and/or paging signals, are transmitted with no closed loop power control. An exemplary peer to peer timing structure includes air link resources allocated for a particular type of signaling in which the resources are segmented into multiple blocks which do not overlap in time, different ones of the multiple blocks being associated with different ranges. The characteristics of the basic transmission units of the multiple blocks based on range are different, e.g., tone size and symbol width are different. A wireless communications device implements the peer to peer timing structure and uses resources from different range based blocks at different times. Data traffic transmission units may be the same regardless of the range.
