[0002] 3GPP长期演进系统(Long Term Evolved, LTE)的一个重要需求,是在保证服务质量(Quality of Service,QoS)的前提下为移动终端提供高速率低延迟业务。 [0002] an important requirement for 3GPP long term evolution (Long Term Evolved, LTE), there is provided a high-speed low delay service for the mobile terminal at ensure quality of service (Quality of Service, QoS) premise. 为减少延迟, 在LTE系统中引入了仅有Ims的传输时间间隔(TransmissionTime Interval, TTI),这就将混合自动重传(Hybrid Auto Repeat Quest,HARQ)的往返时延(Round Trip Time,RTT) 降低到8ms。 To reduce the delay introduced in the LTE system is only a transmission time interval Ims of (TransmissionTime Interval, TTI), which hybrid automatic retransmission (Hybrid Auto Repeat Quest, HARQ) round-trip time (Round Trip Time, RTT) down to 8ms.

[0003] 但是引入较短的TTI也带来了一些问题:当移动终端处于小区边界时,由于上行功率受限,在一个TTI中没有足够的能量而导致基站无法正确解码实现接收,因此往往需要延迟8ms进行HARQ重传,但HARQ重传又会引入多余的8ms的延迟,而且很可能因为过多的重传而丢包,降低了小区覆盖。 [0003] However, introducing a shorter TTI also brings some problems: when the mobile terminal at the cell boundary, since the uplink power is limited, there is not enough energy in one TTI and the base station fails to achieve correct decoding receiver, and therefore often need 8ms delay for HARQ retransmission, the HARQ retransmission is introduced excess will delay of 8ms, and probably because of excessive loss of retransmissions, reducing the cell coverage.

[0004] 为解决上行功率受限的问题,现有技术采用了时域绑定(bundling)的方法,即在连续4个TTI上发送相同的传输块,HARQ反馈(ACK/NAK)都是在最后一个传输+4的位置发送。 [0004] In order to solve the problem of limited uplink power, the prior art method of using a time-domain binding (bundling), i.e. the same transport block transmitted on four consecutive TTI, HARQ feedback (ACK / NAK) are in +4 last transmitted transport position. 在实现本发明过程中,发明人研究发现现有技术至少存在如下问题:时域绑定的方法会增大HARQ的往返时延,导致丢包率增大,降低小区覆盖,降低系统性能。 In implementing the present invention, the inventors found that the prior art has at least the following problems: The method of time-domain binding HARQ round trip delay increases, resulting in increased packet loss, reduce cell coverage, reduce system performance.
