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.

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： 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 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： Methods and apparatus for using high power narrow signals, e.g., tones, for communicating transmitter information without putting the full transmission power available into the transmitted tone or tones are described. User data is transmitted in parallel with transmitter information in many embodiments with the user data being allocated more than 20% of the transmitter's maximum output power in many cases. Buy using an amount of power on the tones used to communicate transmitter information while simultaneously transmitting user data with more than 20% of the available transmission power, efficient bandwidth utilization is achieved while still ensuring a high probability that that the transmitter information signals will be received and detectable using simple energy detection techniques and without the need for timing synchronization with the transmitter to be achieved for success interpretation of the transmitter information.

摘要： A wireless terminal using OFDM signaling supporting both terrestrial and satellite base station connectivity operates using conventional access probe signaling in a first mode of operation to establish a timing synchronized wireless link with a terrestrial base station. In a second mode of operation, used to establish a timing synchronized wireless link with a satellite base station, a slightly modified access protocol is employed. The round trip signaling time and timing ambiguity between a wireless terminal and a satellite base station is substantially greater than with a terrestrial base station. The modified access protocol uses coding of access probe signals to uniquely identify a superslot index within a beaconslot. The modified protocol uses multiple access probes with different timing offsets to further resolve timing ambiguity and allows the satellite base station access monitoring interval to remain small in duration. Terrestrial base station location/connection information is used to estimate initial timing.

摘要： A wireless microphone receiver is used to control transmission power and/or channel configuration of wireless microphones which communicate audio data to the wireless microphone receiver. In some embodiments the wireless microphone receiver searches for available channels, e.g., on a periodic or other basis. Based on wireless microphone receiver loading and interference considerations, channel availability may be determined and channel assignments are made. In some embodiments channel assignments are made based on wireless microphone battery status. Channel assignments to wireless microphones are communicated via a control channel. In addition to channel assignments, wireless microphone transmitter power can be controlled by the wireless microphone receiver. Commands to increase or decrease transmission power may occur as channel conditions change and/or on a recurring periodic basis. The rate of power control transmission may be relatively infrequent, e.g., a second apart in some embodiments, given that wireless microphones tend to be relatively stationary during use.

摘要： Techniques for performing automatic gain control (AGC) at a receiver are described. The receiver may receive an OFDM-based symbol composed of a cyclic prefix and a useful portion. The receiver may scale the OFDM-based symbol with an initial receiver gain, adjust the initial receiver gain based on the cyclic prefix, apply the adjusted receiver gain prior to the useful portion, and process the useful portion to recover at least one signal sent by at least one transmitter. The receiver may select the initial receiver gain, e.g., based on a predicted received power level for the at least one transmitter, a pattern of different receiver gains, etc. The receiver may apply the initial receiver gain at the start of the OFDM-based symbol. The receiver may measure the power of a set of samples in the cyclic prefix and may adjust the receiver gain based on the measured power and a target power.
