Abstract:
Base stations may include a plurality of antenna ports adapted to communicatively couple to respective remote antenna units. A base station simulcast controller module may be coupled with each antenna port, and may be adapted to transmit downlink transmissions over a plurality of remote antenna units, with two or more of the remote antenna units simulcasting downlink transmissions as a simulcasting group. In response to one or more obtained network traffic parameters, the base station simulcast controller module may modify the simulcasting group to include at least one different remote antenna unit. Methods operational on base station may include transmitting downlink transmissions over a plurality of remote antenna units, where two or more of the remote antenna units form a simulcasting group. The simulcasting group can be modified to include at least one different remote antenna unit in response to one or more obtained network traffic parameters.

Abstract:
A wireless communication network uses backhaul negotiation based upon static and dynamic resource assignment on jamming graphs. Static reuse factor design methods including fractional frequency reuse (FFR) are addressed. The jamming graph is used to summarize the interfering relationship between transmitters (nodes in the jamming graph). Negotiation-based algorithm is used to arrive at a static resource assignment so that a large reuse factor can be achieved while jamming scenario can be avoided. As a result of such algorithm, each transmitter is assigned some resources, over which traffic transmission can be done instantaneously to reduce the packet delay for short packets. Based on the result of static resource negotiation algorithm, a dynamic resource algorithm can be run, such that the resources assigned to different nodes can be share in a bursty traffic scenario to further reduce packet delay for larger packet size cases, while jamming be also avoided.

Abstract:
The present invention provides a current controlled oscillator comprising a first section providing a first differential output and a second section providing a second differential output. A loading structure comprised of resistive and reactive elements electrically connects the first differential output with the second differential output. The resistive and reactive elements have values chosen such that the resistive elements substantially extend the linear operating frequency range of the current controlled oscillator. Transistors of the loading structure have which are tied to a power supply rejection ratio compensation section for compensating for variations in power supply voltage.
Abstract:
The present invention includes a method for a combined use of a local positioning system, a local RTK system and a regional, wide-area, or global differential carrier-phase positioning system (WADGPS) in which disadvantages associated with the local positioning system, the RTK and the WADGPS navigation techniques when used separately are avoided. The method includes determining a first position of the object based on information from the WADGPS, and determining a second position of the object based on position information from a local positioning/RTK positioning system. Thereafter, position determined by the WADGPS and the position determined by the local positioning/RTK positioning system are compared. The WADGPS position is used for navigating the object when the WADGPS position and local positioning/position differ by more than a predefined threshold, and using the local positioning/RTK position for navigating the object when the WADGPS position and local positioning/RTK position differ by less than the predefined threshold.
Abstract:
A silver dispersion is obtained by reducing a silver compound in the presence of a polymeric dispersant of an ionic hydrophilic segments, such as methacrylic acid segments con and nonionic hydrophilic segments such as hydroxyl terminated polyethylene glycol segments. Aqueous inkjet inks may contain such dispersants and other common ingredients such as a humectant. The inks can be printed on ceramic substrates and sintered under heat to form solid, conductive patterns of silver.
