    摘要： Methods and apparatuses are provided for CDMA (code division multiple access) access availability to a large cell area, and for traffic channel establishment. A group of cell site modems are configured to look for access attempts generated in respective complete and/or sectorized circular or annular shaped areas centered at the center of the cell area, the areas collectively covering the cell area. To achieve this, each cell site modem has a local clock and the local clock within the first of the cell site modems is synchronized with a standard network time, and the local clock of each of the subsequent cell site modems is offset by a respective delay with respect to the standard network time which causes the cell site modem to search within its respective annular shaped area. A cell site modem is also made available as a traffic cell site modem and is operable to have its traffic acquisition search window centered at a location of an access attempt. Alternatively, a plurality of traffic cell site modems may be provided, each having dedicated circular or annular coverage areas within the cell. The traffic cell site modems also preferably have a local clock which may be synchronized, either to a standard network time, or to a respective delay which causes it to search in its respective area. Methods and for handing off between circular and annular shaped traffic coverage areas are also provided.

    摘要： A valley current mode DC-to-DC converter may include an electronic control system configured to cause the DC-to-DC converter to operate under a continuous current mode and a discontinuous current mode. The electronic control system may include a current sensing system configured to sense current traveling through an inductance, a dual threshold generator configured to generate a first and a different second threshold, and a comparator system configured to compare current sensed by the current sensing system with the first threshold when the DC-to-DC converter is operating in the continuous current mode and with the second threshold when the DC-to-DC converter is operating in the discontinuous current mode.

    摘要： The present invention provides a method and apparatus for improving wireless communication network performance and efficiency, based on detecting the occurrence of grant loss in relation to the transmission of scheduling grants to mobile terminals over a downlink control channel. Grant loss detection is based on detecting erasure events corresponding to the transmitted scheduling grants, and the incidence of grant loss with respect to a given mobile terminal can be tracked and used to compensate the control value(s) used for link adaptation of the downlink control channel, with respect to that terminal. Additionally, or alternatively, when a given grant is determined to be lost, a new grant is sent and the HARQ redundancy version is reset for the newly scheduled transmission.
