摘要： A method and system for wireless data transmission between at least three stations use multiple frequency bands for simultaneous channel communications. The method includes transmitting a Request To Send (RTS) packet from a first station to an intermediate second station over a first frequency band. Two Clear To Send (CTS) packets, which CTS packets include transmission timing information, are then transmitted from the second station simultaneously both to the first station and to a third station. The CTS packet sent to the first station is transmitted over the first frequency band and the CTS packet sent to the third station is transmitted over a second frequency band. A data packet from the first station is then transmitted to the second station. The third station suspends, based on the transmission timing information included in the CTS packets, any unicast transmission to the second station during the transmission of the data packet from the first station to the second station.

摘要： A method and apparatus for frequency correction of a signal in a wireless local area network (WLAN) communication system is disclosed. The signal is processed to determine a frequency offset estimate which is a frequency deviation of the signal from a local oscillator. The signal is then shifted by an amount corresponding to a frequency correction estimate where the frequency correction estimate is an averaged value of the frequency offset estimate and at least one prior frequency offset estimate. Finally, the frequency correction estimate is utilized to correct signals in the WLAN communication system.

摘要： A receiver (200) is provided receiving signals from differing base stations (BTSA and BTSB). The signal from BTSA is encoded using a first rate convolutional encoder while the signal transmitted from BTSB is encoded using a second rate convolutional encoder. Since the multiple base station links may result in a different number of symbols being received for each bit transmitted, the symbols received for each link cannot be simply combined. Therefore, in the preferred embodiment of the present invention, the resulting symbols are passed to multiple branch metric circuits (210–211), where branch metrics (μi) for the symbols are obtained. After the ith branch metrics for the base stations are computed, the branch metrics for each base station are passed to a combiner (212) where they are combined.

摘要： Methods and systems are provided for transmission power control in a multiple access communication system, providing power ramping of a noise floor power level in advance of a high data rate transmission, at a comparatively higher power level, by a mobile station. The preferred method includes receiving a request at a base transceiver station (BTS) for a data transmission by a first mobile station of a plurality of mobile stations (300), the data transmission to have a predetermined data transmission power level; measuring a noise floor power level (305); and comparing the measured noise floor power level to the predetermined data transmission power level (310). When the measured noise floor power level is less than the predetermined data transmission power level, the BTS schedules the data transmission from the first mobile station to occur following the power ramping of the noise floor, and directs the plurality of mobile stations to incrementally increase their transmit power levels to ramp the noise floor power level. Other methodologies to ramp the noise floor power level include injecting analog or simulated noise into the receive path of BTS, or directing the mobile station to transmit meaningless data at increasing power levels prior to transmission of requested data.
