摘要： Wireless devices, e.g., in a cognitive radio network, discover and use locally available usable spectrum for communication. Beacon signaling facilitates available spectrum discovery and spectrum usage coordination. A wireless terminal, which may have entered a new area and powered up, monitors to detect for the presence of beacon signals in a first communications band. The wireless terminal makes a decision as to whether or not to transmit based on the monitoring result. In addition, when beacon signals are detected, decoded information recovered by the wireless terminal from the received beacon signals is used in making the transmission decision. The decoded information includes, e.g., type information indicating that a second band is allowed to be used for peer-peer communications and/or identification information identifying at least one of a wireless communications device which transmitted the beacon signal and a current user of the wireless communications device which transmitted the beacon signal.

摘要： A wireless terminal supports both peer to peer communications and access node based communications. The wireless terminal considers and evaluates communications link alternatives and selects between (i) communication using a peer to peer link and (ii) communications using a link, with a base station serving as an access node, Received signals corresponding to each of the link alternatives are used in performing link quality determinations. In one example, a received user beacon sisal :from a peer wireless terminal is the received signal used for the peer to peer link evaluation and a: base station beacon signal is the received signal used for the access node link evaluation. A link is selected as a function of quality determination, predicted data throughput, link maintenance energy requirements, and/or least cost routing determination information.

摘要： Downlink traffic channel data rate options and methods of indicating to a wireless terminal a utilized downlink data rate option are described. The downlink traffic channel rate option for a segment is conveyed using an assignment signal and/or a block in the downlink traffic channel segment which is not used for user data. Downlink segment assignment signals in some implementations allocate fewer bits for rate option indication than are required to uniquely identify each option. In some implementations low rate options, e.g., using QPSK, are uniquely identified via assignment signals. Higher rate options, e.g., using QAM16 modulation, are conveyed via the distinct information block in the downlink traffic segment using a first coding/modulation method. Still higher rate options, e.g., using QAM16, QAM64, or QAM256, are conveyed via the information block in the segment using a second coding/modulation method which is applied to the rate option information.

摘要： Peer to peer communication timing, e.g., for an ad hoc network, is referenced with respect to an external broadcast signal from a terrestrial or satellite based transmitter. Wireless terminals, seeking to communicate via peer to peer communications, receive the reference broadcast signal, and set their internal timing structure with respect to the reference signal. This facilitates peer to peer timing coordination. A wireless terminal transmits a signal, e.g., a user beacon signal identifying its presence, during a time interval during which another wireless terminal is expected to be monitoring. Reference signal based coordinated timing and use of user beacon signals allows the wireless terminals to maintain situational awareness and coordinate peer to peer communications, while keeping power consumption low, since wireless terminal modules can be powered down during predetermined intervals in the coordinated timing structure where the wireless terminal does not need to transmit and/or receive.

摘要： A first mobile node supports peer to peer communications but not cellular communications. Other mobile modes in the communication system support a cellular mode and may support a peer to peer communications mode. The communications system is such that spectrum may be dynamically reallocated between being designated to be used for peer to peer operations and being used primarily for cellular network based operations. Beacon signals are used to communicate a current mode of frequency spectrum usage designation. The first mobile node, being in an ongoing peer to peer communications session detects that the spectrum is being reallocated for cellular based operations. The first mobile node reduces its transmission power level in response to the detected spectrum reallocation. In some embodiments, the first mobile is allowed to continue its ongoing peer to peer session while the spectrum is primarily allocated for cellular communications, albeit at a lower transmission power level.

摘要： Wireless terminals receive beacon signals from other communication devices and make transmission decisions based on priority information communicated by the beacon signals. Priority information communicated in a beacon signal includes, e.g., one of device priority, user priority and session priority. A wireless terminal compares priority information recovered from received beacon signals with its own current level of priority. A transmission decision based on received priority information includes deciding not to transmit user data when received priority information indicates a higher priority than its own priority level. Another transmission decision based on received priority information includes deciding to transmit user data when the received priority information indicates a lower priority than its own priority level. Other exemplary transmission decisions, performed as a function of priority information from beacon signals, include deciding to perform a transmission power level adjustment and deciding to terminate an ongoing communications session.

摘要： A wireless terminal determines a desired mode of base station operation with regard to whether the base station is to function as a network access node or is to function in a peer to peer mode with regard to a frequency band, and communicates a change signal to the base station. Some change signals are request signals requesting a base station to dynamically reallocate spectrum usage, while other change signals are command signals ordering the base station to reallocate spectrum usage. Information indicating a level of authority corresponding to the change signals, in some embodiments, corresponds to one of a device identifier, a user identifier, and a priority level indicator. An exemplary command signal comes from a device used by a government agent with the authority to override spectrum usage.

摘要： Methods and apparatus supporting efficient paging in a wireless communications system supporting both access node based communications and peer to peer communications are described. Paging timing intervals are set aside in the timing structure such that multi-mode wireless terminals can monitor, e.g., in an infrastructure band, for pages from a base station whether the wireless terminal is operating in a base station attachment point mode or is operating in a peer to peer communications mode. Wireless terminals operating in a peer to peer mode, e.g., using a non-infrastructure band, suspends peer to peer communications during the paging intervals. The time periods, in which the wireless terminal checks pages are, in some embodiments, predetermined, so that both the wireless terminal and base station are synchronized on when a page should be delivered. This synchronization helps reduce the wastage of session time in the peer to peer sessions.

摘要： Wireless devices, e.g., in a cognitive radio network, discover and use locally available usable spectrum for communication. Beacon signaling facilitates available spectrum discovery, spectrum usage coordination, and device identification. A wireless terminal, which may have entered a new area and powered up, monitors to detect for the presence of beacon signals in a communications band. When the wireless terminal fails to detect a beacon, the wireless terminal assumes that the spectrum is available and transmits its user beacon signal thereby providing notification of its presence in the area to other wireless terminals. The wireless terminal maintains a coordinated timing relationship between its beacon transmit interval and beacon detect interval, which are performed on an ongoing basis. The combination of beacon TX interval and beacon monitoring interval represents a small fraction of total time, allowing for power conservation. The coordinated timing relationship, known to peers, facilitates efficient peer-peer communications session establishment.
