| 20100272089 | METHOD AND APPARATUS FOR PROCESSING MULTIPLE COMMON FREQUENCY SIGNALS THROUGH A SINGLE CABLE USING CIRCULATORS - A method and apparatus for processing multiple signals at a common frequency combined into a single radio frequency cable and subsequently recovering the signals without significant losses, distortion, or cross-talk. The method and apparatus includes processing multiple signals at a common frequency fed through a single radio frequency (RF) cable with or without one or more amplifiers and utilized for either forward or reverse link transmissions. The invention enables a single power amplifier to amplify multiple RF signals that occupy a common frequency channel and after amplification splitting these signals into amplified copies of the originals. The amplified signals may be sent to different antenna ports to illuminate different base station sectors if required. The signal splitting function is performed at the antenna masthead such that this method reduces the number of feeder cables running up the antenna tower by a factor of N, where N is the number of common frequency signals (e.g., the number of sectors) amplified by the single power amplifier. This invention enables a single power amplifier to simultaneously provide all the radio frequency signals necessary to feed a general N input phased array antenna system and form multiple antenna beams uniquely for several individual users simultaneously. | 10-28-2010 |
| 20110051709 | SELECTIVELY MANAGING MOBILE STATION SUBSCRIPTIONS BETWEEN FULLY USED ZONES AND SEGMENTED ZONES - A base station receives a connection request from a mobile station. A scheduling module determines whether the fully used and/or segmented zones of the base station are oversubscribed. If the fully used zone is oversubscribed while the segmented zone is not, the mobile station having the largest CINR difference between the zones is assigned to the segmented zone. If the segmented zone is oversubscribed while the fully used zone is not, the mobile station having the smallest CINR difference between the zones is assigned to the fully used zone. If neither zone is oversubscribed and the segmented zone allows modulation/coding more spectrally efficient than the fully used zone, the requesting mobile station is assigned to the segmented zone. If neither zone is oversubscribed and the segmented zone does not allow modulation/coding more spectrally efficient than the fully used zone, the requesting mobile station is assigned to the fully used zone. | 03-03-2011 |
