Abstract: 실시예들에서, 무선 수신기는 펌웨어에 의해 제어되는 하드웨어-기반 고속 푸리에 변환(FFT) 엔진을 사용한다. FFT 엔진은 작업 목록에 저장된 작업들을 실행시킨다. 각각의 작업은 신호의 상이한 일부분, 예컨대 하나 이상의 직교 주파수 분할 변조(OFDM) 심볼들과 연관된다. 각각의 작업은, 상기 엔진이 상기 신호의 상기 연관된 일부분, 상기 일부분에 대한 포인터, 그리고 출력을 저장하기 위한 메모리에 대한 다른 포인터를 프로세싱하도록 구성하기 위해 FFT 엔진을 위한 구성 정보를 포함할 수 있다. 상기 작업 목록은 펌웨어 제어될 수 있다. 작업 목록으로부터 작업들을 판독하여 실행시키기 위해 펌웨어에 의해 구동되는 구성가능한 하드웨어 파트로 상기 FFT를 분할하는 것은 FFT 프로세스의 속도를 높일 수 있고, 더욱 유연성 있게 한다. 서브-캐리어들을 그들의 에너지들에 따라 정렬하기 위한 하드웨어 비콘 정렬기가 상기 FFT 엔진에 커플링될 수 있다.

Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies for performing adjustments for interference management and delta-based power control in a wireless communication system.SOLUTION: A terminal can utilize one or more delta-based power control techniques upon engaging in a reverse link transmission after a predetermined period of silence or after receiving indications of interference from neighboring access points. A delta value can be computed (506) through open-loop projection, on the basis of which transmission resources such as bandwidth and/or transmit power can be increased or decreased (508) to manage interference caused by the terminal. A delta value can also be communicated as feedback to a serving access point to allow the access point to assign transmission resources for the terminal.

Abstract: In embodiments, a wireless receiver employs a hardware-based Fast Fourier Transform (FFT) engine controlled by firmware. The FFT engine executes tasks stored in a task list. Each task is associated with a different portion of a signal, for example, one or more Orthogonal Frequency Division Modulated (OFDM) symbols. Each task may include configuration information for the FFT engine for configuring the engine to process the associated portion of the signal, a pointer to the portion to be processed, and another pointer to the memory for storing the output. The task list may be firmware controlled. Division of the FFT into a configurable hardware part driven by firmware to read and execute the tasks in the task list may speed up the FFT process and make it more flexible. A hardware beacon sorter may be coupled to the FFT engine to sort the sub-carriers according to their energies.
