Abstract: PROBLEM TO BE SOLVED: To improve the utilization of the forward link, and to reduce a transmission delay by high rate packet data transmission in a data communication system capable of variable rate transmission. SOLUTION: Data transmission on the forward link is time-multiplexed and a base station transmits data at the highest data rate supported by a forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of forward link signals as measured at a mobile station. Upon the 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 the retransmission of the data packet which is erroneously received. The data packet can be transmitted to the outside of a sequence by the use of a sequence number to identify each data unit in the data packet. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To improve use of forward direction link and reduce delay in transmission of high rate packet data in the data communication system enabling variable rate transmission.
SOLUTION: Data transmission in the forward direction link 50 is time-multiplexed and a base station 4 executes transmission to a mobile station 6 in the maximum data rate supported with the forward direction link 50 in each time slot. The data rate is determined by the C/I measurement where the forward direction link signal becomes largest as measured at the mobile station 6. When a data packet received erroneously is determined, the mobile station 6 transmits a NACK message to be returned to the base station 4. The NACK message results in re-transmission of the data packet received erroneously. The data packets can be transmitted out of sequence by the use of the number of sequences to identify each data unit within the data packets.

Abstract: PROBLEM TO BE SOLVED: To improve utilization of the forward link and to decrease the transmission delay through high rate packet data transmission in a data communication system capable of variable rate transmission. SOLUTION: 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. COPYRIGHT: (C)2009,JPO&INPIT

Abstract translation: 要解决的问题：提高前向链路的利用率，并通过能够进行可变速率传输的数据通信系统中的高速率分组数据传输来降低传输延迟。 解决方案：前向链路上的数据传输被时分复用，基站以每个时隙的前向链路支持的最高数据速率发送到一个移动台。 数据速率由在移动台测量的前向链路信号的最大C / I测量来确定。 在确定错误地接收到的数据分组时，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。 数据分组可以通过使用序列号序列发送，以识别数据分组内的每个数据单元。 版权所有（C）2009，JPO＆INPIT
