    摘要： A cellular communication system in which a system user and another user communicate with each other by way of information carrying spread spectrum modulated signals transmitted via a cell-site in which system: the system user comprises a transmitter for transmitting information carrying spread spectrum modulated signals to said cell-site, a receiver for receiving information carrying spread spectrum modulated signals from said cell-site and means for measuring signal quality in said information carrying spread spectrum modulated signals received by the system user; the cell-site comprises a transmitter for transmitting information carrying spread spectrum modulated signals to said system user, a receiver for receiving information carrying spread spectrum modulated signals from said system user and adjusting means for adjusting the power of information carrying spread spectrum modulated signals transmitted from the cell-site ; ; and power control means is provided for controlling the transmission power of the information carrying spread spectrum modulated signals by measuring the signal power in the information carrying spread spectrum modulated signals received by the system user and transmitting data representing the measured power to the cell-site by way of the information carrying spread spectrum modulated signals, the adjusting means being responsive to the data in the information carrying spread spectrum modulated signals from the system user to adjust the power in the information carrying spread spectrum modulated signals transmitted by the cell-site.

    摘要： In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate supported by the forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets.

    摘要翻译： 在能够进行可变速率传输的数据通信系统中，高速率分组数据传输提高了前向链路的利用率并且降低了传输延迟。 前向链路上的数据传输是时分多路复用的，并且基站在每个时隙以前向链路支持的最高数据速率向一个移动站发送数据。 数据速率由在移动台处测量的正向链路信号的最大C / I测量来确定。 在确定接收到错误的数据分组后，移动台将NACK消息发送回基站。 NACK消息导致错误地接收到的数据分组的重传。 数据包可以通过使用序号来顺序传输以识别数据包内的每个数据单元。
