    摘要： A system and method for multiplexing subchannels in an OFDMA network is provided. The subchannels can be multiplexed by splitting the subchannels in the frequency domain. Alternatively, the subchannels can be code division multiplexed using N orthogonal spreading codes. The subchannel multiplexing increases system capacity for low-rate services, such as voice-based services.

    摘要： Systems and methods for supporting multiple wireless communication technologies within a cell are provided. A base station can transmit a second wireless communication technology in a smaller coverage than the coverage of the first wireless communication technology, thereby producing an underlay-overlay cell radiation pattern. Whether a mobile station communicates with the base station using the first or second wireless communication technology can be based on a comparison of signal quality measures for the mobile station, or any other performance metric with a fixed or dynamic threshold.

    摘要： Systems and methods for supporting multiple wireless communications technologies are provided. When a first and second base station operate according to different wireless communication technologies on the same carrier frequency in different cells or on different carrier frequencies in the same cell the frame structure of each base station is controlled in such a way that idle periods of transmissions from one base station are aligned with idle periods of the other base station. When the first and second base stations are located in the same cell and operate on the same carrier frequency the frames of the first and second base stations are time-interlaced.

    摘要： Methods and systems are provided for overload control in a wireless communication system. An overload control mechanism identifies an instance of use to eliminate from among a plurality of instances of use in a wireless coverage area. In an overload situation, the overload control mechanism may, for each instance of use, determine a respective ratio of the value of instance of use to the quantity of resource consumed by the instance of use. The overload control mechanism may then sort the instances of use in order of determined ratios to produce a sorted order of the instances of use. The overload control mechanism may select as many instances of use as possible, such that the total amount of resources consumed by the selected instances of use is as high as possible without exceeding the threshold load, and then the overload control mechanism may eliminate the remaining instances of use.
