Description

Data transmission method and device

Technical field

The present invention relates to the communications field, in particular to a kind of data transmission method and device.

Background technology

Capacity and covering are two important performance index in wireless communication system, for the increase capacity, generally adopt the identical frequency process networking, but the identical frequency process networking have increased presence of intercell interference, thereby cause covering performance to descend.

For example, at Long Term Evolution (Long Term Evolution, referred to as LTE) in the system, descending OFDM access (the Orthogonal Frequency Division Multiple Access that adopted, referred to as OFDMA) technology, up single carrier-frequency division multiple access access (the Single Carrier-Frequency Division Multiple Access that adopted, referred to as SC-FDMA) technology, but because general employing identical frequency process networking, presence of intercell interference (Inter-Cell Interference is referred to as ICI) increases obviously.In order to reduce ICI, LTE has adopted some Anti-Jamming Techniques, for example, and descending inter-cell interference cancellation (Inter-Cell Interference Cancellation is referred to as ICIC).Descending ICIC technology is based on Node B (the evolved Node B of evolution, referred to as eNodeB) Relative Narrowband TX Power (Relative Narrowband TX Power, referred to as RNTP) restriction method realize in advance prompting function of descending interference, strengthened the covering performance of physical down Traffic Channel (Physical Downlink Shared Channel is referred to as PDSCH); Up based on (High Interference Indication/Overload Indication, referred to as HII/OI) the ICIC technology, strengthened the covering performance of physical uplink Traffic Channel (Physical Uplink Shared Channel is referred to as PUSCH).

In addition, chnnel coding (Channel Coding) technology and multiple-input and multiple-output (Multiple Input Multiple Output, referred to as MIMO) technology has significant contribution improving link transmission performance, so that data can be resisted the various declines of channel.Wherein, the MIMO technology is passed through space diversity, spatial reuse and beam forming technique also can improve covering performance and the volumetric properties of LTE system, the coordinate multipoint that especially technical development is got up based on MIMO (Coordinated Multiple Point is referred to as CoMP) technology.But, MIMO technology and CoMP technology depend critically upon measurement and the feedback of channel condition information, wireless system is within current and following a period of time, the low-down terminal of signal to noise ratio (User Equipment is referred to as UE) remains bottleneck to measurement and the feedback of wireless channel, and feedback is got over complete and accurate on the one hand, feedback quantity is larger, be a challenge to capacity and coverage distance, on the other hand for Quick-Change channel, feedback delay and accuracy are difficult to ensure.So for covering limited UE, closed-loop MIMO technology and CoMP technology are difficult to obtain due gain, and often adopt simple and practical open loop MIMO technology.The open loop MIMO technology generally combines with resource frequency-hopping, because resource frequency-hopping belongs to a kind of resource allocation techniques of accurate open loop, determines follow-up resource distribution by frequency-hopping mode and initial resource allocation, thus saving resource assignment overhead and feedback overhead.

Can improve the transmission performance of system although there are multiple technologies in the LTE system, especially covering performance, but network test and emulation are found by experiment, the PUSCH of intermediate data rate, the PDSCH of high data rate and ip voice (Voice over IP is referred to as VoIP) business remains in the LTE system the limited channel of covering performance in each channel.Wherein main cause is: the transmitted power of UE is limited to cause the PUSCH of intermediate data rate and VoIP limited, and the ICI between the base station causes the PDSCH of high data rate limited.This covering performance to the LTE system has proposed demand, and the LTE system has introduced Transmission Time Interval (Transmission Time Interval is referred to as TTI) binding (Bundling) technology for this reason.The TTIBundling technology forms different redundancy versions to whole packet by chnnel coding, different redundancy versions transmits in continuous a plurality of TTI respectively, and transmit also in assessment among discrete a plurality of TTI, TTI Bundling technology is by taking more transfer resource, obtain coding gain and diversity gain, obtaining higher received energy and link signal to noise ratio, thereby improve the covering power of LTE system.Because TTI Bundling technology is to exchange covering performance for by reducing spectrum efficiency, be mainly used in the low-down terminal of signal to noise ratio, generally speaking, low-down UE can also improve covering performance by diversity technique for signal to noise ratio, frequency diversity technique for example, in existing LTE standard technique, TTI Bundling and frequency diversity can be used simultaneously, but when existing TTI Bundling technology combines with existing frequency diversity technique, the acquisition of frequency diversity gain and the increase of control overhead have been limited to a certain extent, because existing frequency diversity technique is not to design for TTI Bundling specially.

For example, as shown in Figure 1: wrap in from first VoIP of UE on the Transmission Time Interval 4 to 7 of Physical Uplink Shared Channel PUSCH and carry out the 1st transmission, to be called as Transmission Time Interval binding length (TTI Bundling Size) be 4 TTI Bundling to 4 continuous TTI in 4 to 7, the control information of TTI Bundling (for example, resource location etc.) by physical downlink control channel PDCCH indication among TTI 0 corresponding to first TTI (TTI 4) among the TTI Bundling, after receiving terminal (for example eNodeB) is received this TTI Bundling, at the downlink physical HARQ of Transmission Time Interval 12 indicating channel (Physical HARQ Indication Channel, referred to as PHICH) upper ack/nack ACK/NACK response message of indicating mixed automatic retransfer request HARQ entity, if respective acknowledgement is replied for the NACK that negates, the 2nd transmission of first VoIP bag (namely retransmitting the first time of this TTI Bundling) will be performed at the Physical Uplink Shared Channel PUSCH of Transmission Time Interval 21 to 24, corresponding mixed automatic retransfer request (Hybrid Automatic Repeat Request, referred to as HARQ) the descending PHICH that replys at Transmission Time Interval 28 of the ack/nack (Acknowledge/Non-Acknowledge is referred to as ACK/NACK) of entity is sent out; By that analogy, until respective acknowledgement for affirming that ACK replys, has perhaps reached the maximum that allows and has attempted the number of transmissions (for example, 4 times), first VoIP bag transmission ending.Similarly, the transmission of n VoIP bag is identical with first VoIP bag transmission principle.From transmission shown in Figure 1 as seen, when the Resource Block type of distributing to TTIBundling is localized resource blocks, namely the Resource Block physical location of two time slots (Slot) in 1 TTI is identical, the physical location of the Resource Block of a plurality of TTI among TTI Bundling is identical, and at semi-persistent scheduling (Semi-Persistent Scheduling, referred to as SPS) under in order to save control overhead, the physical location of the Resource Block among the continuous TTI Bundling is identical, and this is with the acquisition of serious limit frequency diversity gain.Although can change the physical location of the Resource Block of TTI Bundling by increasing the transmission of PDCCH, obviously control overhead obviously increases, and the physical location of the Resource Block of a plurality of TTI among TTI Bundling is identical; When the Resource Block type of distributing to TTI Bundling is localized resource blocks, namely the Resource Block physical location of two time slots (Slot) in 1 TTI is different, 1 two interior time slot of TTI can not adopt joint channel estimation, and channel estimation accuracy descends, and also can reduce systematic function.

Although, on the TTI of LTE R8 Bundling technical foundation, the TTI Bundling technology that strengthens has been proposed, for example, as shown in Figure 2.Be spaced apart 4 TTI between two TTI Bundling, first pass and retransmit can adopt a HARQ process or a plurality of (for example, 2) the HARQ process, similarly, be spaced apart 8 TTI between two TTI Bundling, first pass and retransmit can adopt a HARQ process or a plurality of (for example, 2) the HARQ process, but the principle of its enhancing all is a VoIP bag head to be passed and retransmit the TTI number that takies at most altogether bring up to 20 from 12 or 16, thereby improve the transmitted power of accumulation or the redundancy versions of increase HARQ, but machine-processed identical with LTE R8 still aspect the resource distribution of TTI Bundling seriously limited the acquisition of frequency diversity gain.

To sum up, for the binding of the Transmission Time Interval in correlation technique technology, because the relatively lower smaller problem of coverage that causes transfer of data of frequency diversity gain not yet proposes effective solution at present.
