摘要： A wireless computing device operating as a controller of a peer-to-peer group configured to generate unique master keys for each device joining the group. The wireless computing device may use the unique master keys to selectively remove remote devices from the group such that the remote device cannot later rejoin the group. Other remote devices, each possessing a master key that remains valid, can disconnect from the group and later reconnect to the group without express user action. To support such behavior, the wireless device may provide a user interface through which a user may manage connected remote devices by providing commands to selectively disconnect or remove remote devices from the group.

摘要： A dock for interacting with a computing device. The computing device configures itself for operations based on its context, which may be determined form the dock by reading a value from a tag on the dock. The computing device may use low power transmissions such that receiving a value from the tag provides an indication of proximity to the dock. The value read provides an indication of a desired operation, and, in response to reading a value of the tag, the computing device may launch an application, pair with devices in the vicinity of the dock, or take other actions that configure the computing device. A universal dock, usable with computing devices of a plurality of form factors, may be implemented by providing an array of tags and, in some cases, a non-contact power supply.

摘要： A cellular communication system in which overload of a base station is averted by offering users the option to communicate using a spectrum outside of the spectrum allocated for cellular communication. Incentives are offered to connect to the base station using the alternative spectrum, which may not support communications at the same rate as could be supported using the spectrum allocated to the base station for cellular communications. Users may be selected to receive an offer to receive incentives based on range to the base station, with users closer to the base station being more likely to receive such an offer. The cellular communications system may be a 3G wireless system and the alternative spectrum may be white space in the digital TV spectrum.

摘要： 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.

摘要： A communication system and method for transmitting relatively short data messages in the communication system. A dedicated frequency is sequentially switched into each of a plurality of satellite beams or traffic channels to transmit data messages at an increased power level to provide an increased signal margin. The increased power level of the dedicated frequency can be combined with coding and bit and message repetition to further increase the signal margin.

摘要： A satellite communication system includes Earth-based terminal and a satellite constellation in non-geosynchronous Earth orbits. When two or more satellites are within range of a first Earth-based terminal, the station requests a communication link with the first satellite at a first data rate. If the first satellite will accept data transfer at the first communication rate, the first Earth-based terminal transmits data to the first satellite at the requested first data rate. If, however, the first satellite will not accept data transfer at the requested first data rate, the first Earth-based terminal transmits a first portion of the data to the first satellite at a second data rate and transmits a second portion of the data, different from the first portion of the data, to the second satellite at a third data rate. The first and second satellites relay the respective data portions to a second Earth-based terminal, either directly or via additional satellites. The second Earth-based terminal reassembles the first and second data portions to recover the original data. The data transfer may be unequal error correction encoded data whereby the second Earth-based terminal may recover the original data from only a portion of the received error correction encoded data.

摘要： A source sequence of symbols is communicated over a communications medium by encoding the source sequence according to respective first and second error correction codes to produce respective first and second encoded sequences of symbols. The first and second encoded sequences are processed to produce a communications signal, which is then communicated over the communications medium. The communicated communications signal is processed to produce first and second received sequences of symbols corresponding to the first and second encoded sequences, respectively. The first and second received sequences are selectively recursively decoded according to the associated error correction codes augmented by previous estimates of a symbol of the source sequence to repeatedly produce revised estimates of the symbol until an estimate satisfying a predetermined reliability criteria is obtained.

摘要： A satellite-cellular communication system includes a satellite based transceiver for transceiving two-way communications originated at a user terminal. As a part of call set up, a controller determines whether the user terminal should transmit in the uplink in either a wide band mode of operation or in a narrow band mode of operation. The controller then specifies to the user terminal the mode of operation through the transceiver.Whether the user terminal transmits in the uplink in a wide band or in a narrow band mode depends upon factors including the type of device, channel usage and efficiency in the channels to and from the satellite transceiver and the signal quality of the signals received at the transceiver.
