Peer-to-peer collaboration of publishers in a publish-subscription environment
Embodiments of the present invention provide an approach for an enhanced pub/sub environment whereby a peer group of publishers is defined and can collaborate to determine when to cache data being sent to a common broker or brokers. Specifically, in a typical embodiment, configuration data or the like will be read to define a peer group among the publisher systems in the pub/sub messaging environment. Once such a group has been identified, communication therebetween will be established. Once cacheable data has been identified, a unique identifier/set of cache keys will be generated corresponding thereto and associated with the set of data. A message comprising the set of data and corresponding unique identifier will then be sent to a broker system (e.g., from the publisher system(s)), which will store (or have stored) the set of data in a cache, and pass the underlying message along to applicable subscriber system(s). |

Signal decomposition methods and apparatus for multi-mode transmitters
A multi-mode communications transmitter includes a signal decomposer that converts rectangular-coordinate in-channel and quadrature channel signals into polar-coordinate amplitude and angle component signals and form therefrom first and second modulation signals. The signal decomposition process performed by the signal decomposer combines envelope-reduction and restoration (ERR) with filtering to reduce the bandwidths of the first and second modulation signals compared to the bandwidths of the unmodified amplitude and angle component signals. The reduction in signal bandwidths eases the design requirements of the electrical components needed to process and generate the signals applied to the power supply and radio frequency (RF) input ports of the multi-mode communications transmitter's power amplifier (PA). It also makes the multi-mode communications transmitter more forgiving to gain and delay mismatches between the signals applied to the power supply and RF input ports of the PA, compared to conventional polar modulation transmitters. |

A radio base station (RBS) is described herein that detects when a high-speed downlink shared channel (HS-DSCH) data frame (110) is lost after it was transmitted by a radio network controller (RNC) over a transport link (Iub) towards the RBS (104). To accomplish this, the RBS (104) upon receiving a HS-DSCH data frame (110) inspects a frame sequence number (302) located within the received HS-DSCH data frame (110) to determine if the frame sequence number (302) is in sequence with a frame sequence number (302) located within a previously received HS-DSCH data frame (110). If the two frame sequence numbers (302) are not in sequence, then one or more HS-DSCH data frames (110) that were previously transmitted towards the radio base station (104) have been lost. If the radio base station (104) detects to many lost HS-DSCH data frames (110a), then it can correct the problem by reducing the bit rate of a certain HS user flow or by reducing the maximum bit rate for all of the HS traffic which is going to be sent by the radio network controller (102) over the transport link (106) to the radio base station (104). |

Accordingly, loads to the power supply that supplies the reference potential of boosting can be reduced. Further, as power for charging the capacitor in the DC/DC converter, power supplied from not an antenna but a secondary battery is used. More specifically, a secondary battery is used as a power supply that supplies power to a buffer circuit or an inverter circuit. Thus, power supplied from the antenna can be stabilized. In other words, operation of a logic circuit and an analog circuit can be stabilized. |
