    摘要： Systems and methods for enhancing the capacity of base stations are provided. A base station can operate in a time division duplex mode within a first frequency band. When a second frequency band is acquired for the base station's geographic region, a duplexer can be added to the base station. The base station can then operate in a frequency division duplex mode, where the first frequency band is used for base station downlink transmissions and the second frequency band is used for uplink transmissions.

    摘要： A method, computer-readable medium, and apparatus for dynamically assigning radio resources between a frequency division duplexing (FDD) carrier and a time division duplexing (TDD) carrier is provided. The method includes monitoring radio frequency conditions and traffic load of the FDD and TDD carriers; allocating a resource assignment for a downlink on the FDD carrier or the TDD carrier, based upon the radio frequency conditions or the traffic load of the FDD and TDD carriers; and allocating a resource assignment for an uplink on the FDD carrier or the TDD carrier, based upon the radio frequency conditions or the traffic load of the FDD and TDD carriers.

    摘要： A method, apparatus and computer-readable medium for improving push-to-talk call setup speed by disabling an idle mode of a mobile station are provided. According to the method, a deregistration request is received from a mobile station. The base station determines whether a push-to-talk service flow exists for the mobile station, based upon a unique identifier for push-to-talk service flow for the mobile station. If the service flow does exist, then the base station transmits a deregistration command to the mobile station including an action code that instructs the mobile station to disable its idle mode and change its mobility feature supported field to sleep only mode. Since the time required to transition from sleep mode to active mode is less than from idle mode to sleep mode, the push-to-talk call setup speed is improved.

    摘要： Systems and methods of testing a wireless network are provided. Simulated user data, spread across all user data sub-carriers of all sub-channels of a frequency band assigned for transmissions, is transmitted by a number of base stations surrounding a base station under test. The power level of the simulated user data is determined based on a selected network load. A mobile station receives signals from the base station under test and the number of base stations, and the interference caused by the simulated user data to the transmission from the base station under test is determined. When less than 100% loading is employed for testing, the sub-channels carrying the simulated user data can vary on a frame-by-frame basis.
