摘要： A method and system are disclosed for providing a temporary peer-to-peer network including a group owner, and one or more deputies able to step into the role of group owner to continue the group session in the event the prior group owner cedes ownership. Each device in the group may include a layered communications protocol having a group maintenance layer between the network layer and the physical layer. The group maintenance layer may be responsible for dictating when and under what conditions a deputy device becomes the group owner so that group membership and activities may move forward without loss of continuity.

摘要： 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.

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. The transmitter is informed by an application that it needs to transmit data a particular rate. The transmitter determines the minimum number of subchannels and maximum energy (or noise) threshold for each subchannel necessary to achieve that data rate and selects a set of subchannels matching those requirements. The subchannels need not be contiguous in the spectrum or belong to the same channel. Once the transmitter has selected the required number of subchannels, it begins transmitting simultaneously on those subchannels across the entire bandwidth used by those subchannels.

摘要： Systems and methods are provided for modularly constructing a software defined radio (“SDR”). Given an SDR kernel (i.e., a potentially platform-neutral definition of digital signal processing functionality and control operations necessary to implement the core portion of a software defined radio implementing a particular radio standard), an optional description of governmental regulations for a particular locality, and an interface harness providing the necessary components for interfacing to specific communication channels and devices (including SDR hardware components), an SDR factory component performs a process of constructing an SDR software component for implementing a particular radio standard on a particular host. The SDR software component may additionally construct components which restrict the operation of the resulting SDR software component. The SDR kernel may be protected by one or more digital rights management (“DRM”) policies which may be enforced both at the time the SDR software component is constructed and while it is operating.

摘要： An application program is disclosed for execution on a computing device capable of supporting network communications via multiple differing communication modes. The application includes a set of user interface elements facilitating easy user selection of one of a set of communication modes supported by the computing device. Thereafter, the selected communication mode is utilized to support communications for the application. The application program also includes an interface to a transport layer component. The interface initiates binding a network interface to an endpoint opened by the application in accordance with the designation of the communication mode. Furthermore, the interface passes transmission requests to the interface identifying the endpoint. Therefore the interface facilitates forcing use of the designated network interface to complete the transmission requests of the application.

摘要： A synchronization method and apparatus for synchronizing a receiver, such as a radiotelephone operable in a cellular communication system with a transmitter. Synchronization signals are transmitted as parts of a control signal to the receiver. Such synchronization signals are of high margins and also permit synchronization of the radiotelephone responsive to a reduced number of calculations. The time for such synchronization is reduced by use of nonlinear transformation metrics, such as logarithmic metrics, which reduce the impact of a noise or error component within the control signal.

摘要： A method for transmitting random access signals from a mobile unit to a satellite or other control station which requires the transmission of less information than in conventional terrestrial cellular or proposed mobile satellite systems. According to the method, the mobile unit acquires synchronization from the satellite and transmits reduced random access information to the satellite, and the satellite calculates time adjustment information for the mobile units based on the reduced random access information. The random access information is reduced by predetermining a slot number for each mobile unit, and by transmitting only the odd or even status of the frame number desired by the mobile unit.
