Abstract: Various technologies described herein pertain to providing spectrum utilization feedback from a whitespace device. A database query for a set of available channels in a spectrum (e.g., broadcast spectrum, etc.) during a time period can be transmitted from the whitespace device to a regulatory authorized database system. The database query includes data that specifies a set of channels used by the whitespace device during a previous time period prior to the time period. Responsive to the database query, a response can be received at the whitespace device from the regulatory authorized database. The response indicates the set of available channels in the spectrum during the time period, where the available channels are unassigned to licensees at a location of the whitespace device during the time period. Moreover, the whitespace device is configured to opportunistically communicate in the spectrum over one or more of the available channels.

Abstract: A multiuser scheme allowing for a number of users, sets of user, or carriers to share one or more channels is provided. In the invention, the available channel bandwidth is subdivided into a number of equal-bandwidth subchannels according to standard OFDM practice. A transmitter transmits data on a set of OFDM subchannels that need not be contiguous in the spectrum or belong to the same OFDM channel. A receiver receives and decodes the data and detects errors on subchannels. The receiver then broadcasts the identity of those subchannels on which the error rate exceeds a specific threshold, and the transmitter may select different subchannels for transmission based on this information.

Abstract: Applicants have discovered that error detection techniques, such as Forward Error Correction techniques, may be used to predict the degradation below a certain threshold of an ability to accurately convey information on a communication channel, for example, to predict a failure of the communication channel. In response, transmission and/or reception of information on the channel may be adapted, for example, to prevent the degradation below the threshold, e.g., prevent channel failure. Predicting the degradation may be based, at least in part, on data transmission error information corresponding to one or more blocks of information received on the channel and may include determining an error rate pattern over time. Based on these determinations, the degradation below the threshold may be predicted and the transmission and/or reception adapted. Adapting may include initiating use of a different error encoding scheme and/or using an additional communication channel to convey information.

Abstract: Systems and methods are disclosed for adapting a communication system to varying conditions. Using some form of discovery protocol, the communication standards supported by at least two communicants are determined. Each communicant may then periodically monitor the quality of the channel established by the communication standard and dynamically select a set of one or more communication standards to use for communicating. Further, when communicants share common non-standard parameterized implementations of communication standards, changes to the protocols which the communication standards comprise can be used to add options for a more dynamic response to changing conditions than is possible when adhering only to an established communication standard.

Abstract: As part of a cryptographic protocol, or in addition to it, a computer may participate in a cryptographic key generation protocol. The cryptographic key generation protocol may be such that it generates a set of bits sufficient for a cryptographic key and, also, one or more additional bits. The cryptographic protocol may have one or more parameters, and the parameters of the cryptographic protocol may be varied as a function of the additional bits generated by the cryptographic key generation protocol. The cryptographic protocol may specify a set of one or more cryptographic key sizes. An overkey may be generated that is at least one bit greater than the set of cryptographic key sizes specified by the cryptographic protocol. The parameters of the cryptographic protocol may then be varied as a function of some subset of bits of the overkey. Cryptography-based security may thus be enhanced.

Abstract: A network node selects a “sleep” level based on its current or projected battery capacity. In an embodiment of the invention, sleep levels define the types of communication to which the node in question will be a party. The node in question communicates its selected sleep level to the rest of the network so that the other network nodes can communicate accordingly with the node.

Abstract: The present invention relates to a method for transmitting multiresolution audio signals via wireless devices in a radio frequency communication system wherein audio signals are decomposed into levels of resolution. The audio signal is decomposed into levels including a base signal at a base transmission rate and one or more signal details and input into a code rate selector, controlled by either party to the communication. The base signal represents the coarsest resolution or quality of the signal. Each signal detail, when added to the base signal, improves the resolution of the signal by increasing the detail and the transmission rate. An audio receiving unit transmits a request for audio transmission to the audio transmitting unit. In response to the initial request, the base signal is transmitted to the audio receiving unit. If the base signal is insufficient, the sound quality can be increased incrementally by sending further requests to transmit additional signal detail from the code rate selector. The additional signal detail is then recombined with the base signal at the audio transmitting unit to provide a higher level of sound quality to the signal. The higher quality audio signal is then transmitted to the audio receiving unit.

Abstract: The present invention relates to a method for transmitting multiresolution image data via wireless devices in a radio frequency communication system wherein images are decomposed into levels of resolution. The image data is stored in discrete information blocks in an image storage unit including a base image and one or more image details. The base image represents the coarsest resolution of the image. Each image detail, when added to the base image, improves the resolution of the image. An image display unit transmits a request for image data to the image storage unit. In response to the initial request, the base image is transmitted to the image display unit. If the base image is insufficient, the resolution can be increased incrementally by sending additional image data requests to transmit additional image detail. The additional image detail is then transmitted to the image display unit and recombined with the base image to provide a higher level of resolution to the image.
