Description

Uplink data transmission method and device
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of uplink data transmission method and device.
Background technology
At LTE (Long Term Evolution, Long Term Evolution) in the system, be subject to UE (User Equipment, subscriber equipment) maximum transmission power, each packet utilizable transmitting power in a TTI (Transmission Time Interval, Transmission Time Interval) is limited, therefore, under abominable channel condition, uplink will be difficult to reach performance requirement.In order to improve up coverage effect, the LTE system has adopted the enhancing technology, has introduced up TTI bundling (binding) scheme.So-called TTI bundling scheme, namely be that UE is based on a scheduling indication of base station, in a plurality of subframes, send same TB (Transport Block, data transmission block) the different RV (RedundancyVersion after chnnel coding, redundancy versions), like this, can improve the transmission of uplink data gain, thereby strengthen the coverage effect of upward signal.These a plurality of sub-frame of uplink are called a binding subframe bundle (bundle).
At present, in the LTE system, regulation bundle size (size) is 4, namely comprises four sub-frame of uplink among a bundle.
For FDD (Frequency division duplex, Frequency Division Duplexing (FDD)) system, after adopting the TTIbundling scheme, UE sends the different RV of same TB in four continuous sub-frame of uplink, decode after the RV that receives is merged in the base station, compare non-bundling (not binding) scheme, the transmitting power of same TB increases, and can obtain higher received signal to noise ratio and throughput.For example, as shown in Figure 1, when not disposing TTI bundling (being non-bundling), up RTT (Round Trip Time, round-trip delay) duration is 8ms, and interior HARQ (Hybrid Automatic Repeat Request the mixes automatic repeat requests) number of processes of RTT is 8; And after having disposed TTI bundling, the duration of up RTT is the twice of former up RTT, i.e. 16ms, and the HARQ number of processes in a RTT reduces by half, namely number is 4.The definition of RTT can for same process be transferred to time interval between the re-transmission for the first time, the situation for adopting TTI bundling is as the criterion with same in-process first subframe.The data block that each HARQ process transmission is different.But the HARQ process adds up to the maximum possible value of having transmitted the number of not receiving transmission result (being that data block is correct or wrong receives) feedback data piece at any one time point.
And for TDD (Time division duplex, time division duplex) system, be subject to the uplink-downlink configuration of standard formulation, the number of continuous sub-frame of uplink is less than the bundle size of regulation, so the different RV of TB will send in discrete sub-frame of uplink.Under the prior art, only designed TTI bundling operation at uplink- downlink configuration 0,1 and 6, will be introduced one by one below.
As shown in Figure 2, at uplink-downlink configuration 0, when non-bundling, in a RRT, the number of ascending HARQ course is 7, and behind configuration TTI bundling, in a RRT, the ascending HARQ course number is to comprise 4 sub-frame of uplink in 3, one bundle.
As shown in Figure 3, at uplink-downlink configuration 1, when non-bundling, in a RRT, the ascending HARQ course number is 4; And behind configuration TTI bundling, in a RRT, the ascending HARQ course number is to comprise 4 sub-frame of uplink in 2, one bundle.
As shown in Figure 4, at uplink-downlink configuration 6, when non-bundling, in a RRT, the number of ascending HARQ course is 6, and behind configuration TTI bundling, in a RRT, the ascending HARQ course number is to comprise 4 sub-frame of uplink in 3, one bundle.
In existing LTE system, bundle size is less, even some TDD uplink-downlink configuration (such as uplink- downlink configuration 2,3,4,5) do not support TTI bundling, has limited up covering.
