摘要： In a first method, a first apparatus determines a channel gain to a second apparatus with which the first apparatus is communicating. The first apparatus determines interferer backoff information that ensures an interference level at the first apparatus such that a signal received from the second apparatus can be decoded reliably. The interferer backoff information is determined based on the channel gain. The first apparatus transmits information based on the interferer backoff information in a message to the second apparatus. In a second method, a first apparatus in communication with a second apparatus determines a channel gain to a third apparatus with which the first apparatus can potentially interfere. The first apparatus receives a message from the third apparatus. The message includes interferer backoff information. The first apparatus determines a power for transmitting a signal to the second apparatus based on the interferer backoff information and the channel gain.

摘要： Techniques for use in contending for a portion of a television channel spectrum are disclosed. In some instances, a back-off value is used to decide whether a contender's contention number will be transmitted when the contention channel is free, and the back-off value is determined based on the contention number. In some instances, a contender monitors the contention channel and withdraws from contention if it detects from the contention channel that a higher priority contender is in contention.

摘要： Transmitting devices facilitate privacy protection of content broadcasted from the transmitting device to a receiving device without the need to modify the receiving device. A transmitting device may be adapted to acquire content, such as audio and/or video data, to be broadcasted by the transmitter for reception and use by a receiving device. A transmission range is selected to define a distance for broadcasting the content from the transmission device for reception and use by a receiving device. A frequency is also selected to be used for broadcasting the content. With the transmission range and frequency selected, the transmitting device may broadcast the content according to the selected transmission range and frequency.

摘要： Multichannel dynamic frequency selection in wireless networks (10, 20) begins with an access point (90, 100, 200) for a wireless network broadcasting a list of unused channels (300, 905) that are available for communication within the area served by the access point. The various access terminals (80, 101, 201) within this service area receive the broadcast and measure (401) various interference characteristics of each of the channels in the list. The access terminals then send (402) this interference information (301, 505) to the access point, which compiles a matrix of interference information (906) that is associated with the quality of each signal as related to each access terminal. Using this information, the access point selects (302, 702) the appropriate channels to serve the most number of access terminals at the highest possible channel qualities.

摘要： In general, techniques are described for sensing wireless communications in television frequency bands, which may be implemented by a sensing device comprising a sensing unit, a power spectral density (PSD) estimation unit, a filter unit, a candidate selection unit, an analysis unit and a decision unit. The sensing unit senses a signal in the television frequencies bands. The PSD estimation unit calculates an estimate of a PSD for the sensed signal. The filter unit filters the estimated PSD. The candidate selection unit analyzes the filtered PSD to identify a candidate frequency representative of a potentially in use frequency. The analysis unit computes a test statistic for the candidate frequency. The decision unit compares the test statistic to a threshold to identify whether the candidate frequencies is actively in use by wireless communication devices.
