Description
Technical Field
The present invention relates to the field of communications, and in particular, to a data transmission method and system.
Background
With the rapid development of wireless communication technology, limited spectrum resources gradually become a main factor restricting the development of wireless communication, but the limited spectrum resources stimulate the appearance of new technology. In a wireless communication system, capacity and coverage are two important performance indexes, in order to increase the capacity, networking is performed in a same-frequency mode, but the inter-cell interference is increased by the networking in the same-frequency mode, so that the coverage performance is reduced.
In a Long Term Evolution (LTE) system, an Orthogonal Frequency Division Multiplexing multiple Access (OFDMA) technology is used in a downlink, which can significantly reduce Interference in a Cell, but Inter-Cell Interference (ICI) is significantly increased due to common-Frequency networking. In order to reduce ICI, LTE also standardizes many techniques, such as Inter-Cell interference Cancellation (ICIC). The Downlink ICIC technology realizes a Downlink interference advance warning function based on a method of eNodeB Relative Narrowband Transmit Power (RNTP) limitation, and enhances the coverage performance of a Physical Downlink traffic Channel (PDSCH). The uplink adopts a Single Carrier-Frequency Division multiple Access (SC-FDMA) technology, so that the peak-to-average ratio of the UE can be obviously reduced, and the signal quality is improved. In order to reduce ICI, many technologies are also standardized in the LTE Uplink, for example, the Uplink ICI technology based on HII/OI enhances a Physical Uplink traffic Channel (PUSCH).
In addition, the Multiple Input Multiple Output (MIMO) technology can also improve the coverage performance and capacity performance of the LTE system through spatial diversity, spatial multiplexing, and beamforming technologies, especially a Coordinated Multiple Point (CoMP) technology developed based on the MIMO technology. However, in the current network, since the terminals (UE) all transmit on a single antenna, the MIMO technology and the CoMP technology have limited improvement on the uplink, and can only be improved by Joint Receiver (JR) at the receiving end.
In addition, Channel Coding (Channel Coding) technology has an important contribution to improving link transmission performance, so that data can resist various fading of a Channel.
Although there are many techniques in the LTE system to improve the transmission performance, especially the network coverage performance, the PUSCH at medium rate, the PDSCH at high rate and the VoIP traffic are still channels with limited coverage performance among the various channels in the LTE system, as confirmed by network tests and software simulation. The main reasons for this are: the limited transmit power of the UE results in limited PUSCH and VoIP for medium rates, while ICI between base stations results in limited PDSCH for high rates. This puts a demand on coverage performance improvement of the LTE system, and for this reason, the LTE system introduces a Transmission Time Interval (TTI) Bundling (Bundling) technique. The TTI Bundling technology forms different redundancy versions for the whole data packet through channel coding, the different redundancy versions are respectively transmitted in continuous TTIs, and the TTI Bundling technology obtains coding gain and diversity gain by occupying more transmission resources so as to obtain higher receiving energy and link signal-to-noise ratio, thereby improving the coverage capability of an LTE system.
Fig. 1 is a schematic diagram of TTI Bundling transmission of a VoIP service in the related art, where as shown in fig. 1, 4 consecutive TTIs are referred to as TTI Bundling Size (TTI Bundling Size) 4, a UE performs TTI Bundling first transmission on TTIs t to t +3 of a PUSCH, an eNodeB receives the TTI Bundling first transmission and then indicates HARQ response information on a Physical HARQ Indication Channel (PHICH) of TTI t +7, and if the response is NACK (Non-acknowledgement), the UE performs TTI Bundling 2 nd transmission (i.e., a first time of TTI Bundling retransmission) on TTIs t +16 to 19 of the PUSCH, and after receiving the first time of TTI retransmission, indicates HARQ response information on a PHICH of TTI + t + 24; and so on, until the acknowledgement is ack (acknowledgement), or the maximum number of allowed attempted transmissions (e.g. 3) is reached, the transmission is terminated. Control information (such as resource position) of TTI Bundling is indicated by a PDCCH corresponding to a first TTI in TTI Bundling.
It should be noted that the transmission principle of using TTI Bundling to transmit Data (Data) service is the same as that of transmitting VoIP service, but the difference is that when the TTI Bundling is used to transmit VoIP service, Data transmission is periodic, and when the TTI Bundling is used to transmit Data service, Data transmission is not periodic.
In the scenario shown in fig. 1, the number of resource blocks in each TTI in TTI Bundling is equal, and although the equal number of resource blocks can simplify the control process of TTI Bundling and reduce the control overhead of TTI Bundling, the equal number of resource blocks in each TTI in TTI Bundling may cause the following problems: the number of resource blocks transmitted per TTI Bundling is the number of resource blocks per TTI × TTI Bundling, which results in that the value of the Transport Block Size (TBS) that can be transmitted in TTI Bundling is limited, which has little impact on the VoIP service, because the TBS of the VoIP service is designed specifically at full rate, for example, TBS 328 corresponds to the full rate of the AMR, and the number of RBs is set from 1 to 9, but for the data service, the rate range is wider, which can reach 1Mb/s from 1kb/s, and the types of TBSs required are more, so when TTI Bundling is applied to data Transmission, the flexibility of TBS selection is poor, which may result in a reduction in resource utilization.

The technical solution of the present invention will be further described in detail with reference to the following specific examples.
Example one
In this embodiment, the number of TTIs N included in the TTI Bundling is 4, and 4 TTIs in the TTI Bundling are consecutive. In this embodiment, 18 RBs are allocated to 4 TTIs in TTI Bundling in total, that is, K is 18, and in an LTE system with a bandwidth of 10MHz, the system bandwidth is configured with NRBIs 50.
According to the foregoing, the allocation method of K resource blocks in N TTIs is as follows:
when K can be evenly divided by N:
in N TTIs in the TTI Bundling, allocating K/N resource blocks in each TTI;
when K cannot be evenly divided by N:
each TTI in R TTIs in N TTIs in TTI Bundling allocates floor (K/N) +1 resource block;
each of N-R TTIs in the N TTIs in the TTI Bundling allocates floor (K/N) resource blocks.
In this embodiment, since R ═ K mod N ═ 18mod4 ═ 2, floor (18/4) +1 ═ 5 RBs are allocated for the first R ═ 2 TTIs (TTI t, TTI t +1), and floor (18/4) ═ 4 RBs are allocated for the last N — R ═ 2 TTIs (TTI t +2, TTI t + 3).
In this embodiment, H versions of HARQ are generated, and the length of each version is:
floor (M Nsc/N), wherein M is a modulation grade, and Nsc is the total number of available data subcarriers after pilot frequency is removed in K resource blocks;

If K is 18 and the modulation scheme is QPSK, then M is 2, and the length of each version is:
floor (M × Nsc/N) ═ floor (2 × 144 × 18/4) ═ 1296, that is, the lengths of HARQ RV x, HARQ RV y, HARQ RV z, and HARQ RV w are all 1296 bits. The corresponding TTI Bundling transmission diagram is shown in fig. 4.
Or,
the length of each version is: m is Nsc, wherein M is the modulation grade, and Nsc is the total number of the available data subcarriers after pilot frequency is removed in K resource blocks;
if K is 18 and the modulation scheme is QPSK, then M is 2, and the length of each version is:
M*Nsc＝2*144*18＝5184。
that is, the lengths of HARQ RV x, HARQ RV y, HARQ RV z, and HARQ RV w are 5184bits, and the corresponding TTI Bundling transmission diagram is shown in fig. 5.
Example two
Fig. 6 is a schematic diagram of TTI Bundling transmission in a second embodiment of the present invention, where the number of TTIs included in the TTI Bundling transmission is fixed, for example, 4 TTIs are provided, but 4 TTIs in time interval Bundling are discontinuous, and a third TTI cannot be allocated due to scheduling collision, so that the first three TTIs and the fifth TTI together form TTI Bundling, and 4 TTIs are still bundled for transmission together, but the time domain width is 5 TTIs, thereby increasing the flexibility of resource scheduling.
The specific allocation principle and version generation principle of this embodiment are similar to those of the embodiment, in order to improve transmission efficiency, a suitable TBS is configured for data to be transmitted, and 18 RBs are allocated for 4 TTIs in TTI Bundling in fig. 6, where the first two TTIs respectively occupy 5 RBs, and the second two TTIs respectively occupy 4 RBs.
EXAMPLE III
Fig. 7 is a schematic diagram of TTI Bundling transmission in a third embodiment of the present invention, where in this embodiment, the number of TTIs included in TTI Bundling transmission is fixed, for example, 4, but 4 TTIs in time interval Bundling are discontinuous. In order to increase the time diversity gain obtained by TTI Bundling in transmission, 4 TTIs are transmitted in 8 TTIs at intervals of 1 TTI.
The specific allocation principle and version generation principle of this embodiment are similar to those of the embodiment, in order to improve transmission efficiency, a suitable TBS is configured for data to be transmitted, and fig. 7 shows that 18 RBs are allocated for 4 TTIs in TTI Bundling, where the first two TTIs respectively occupy 5 RBs, and the second two TTIs respectively occupy 4 RBs.
Need to explain: the interval of 1 TTI is only an example, and a plurality of TTIs may be spaced, with the difference that the transmission delay is different from the obtained time diversity gain.
Example four
Fig. 8 is a schematic diagram of TTI Bundling transmission in a fourth embodiment of the present invention, in which the number of TTIs included in the TTI Bundling transmission is fixed, for example, 4, but 4 TTIs in the time interval Bundling are discontinuous.

However, the difference between this embodiment and embodiments one to three is that only 1 HARQ version is transmitted in 4 TTIs in fig. 8.
The transmitting end in the present invention may be a base station, a home base station, a relay station, or other devices, or may be a communication terminal, a notebook computer, a handheld computer, or other devices. Similarly, the receiving end is configured to receive the data signal from the transmitting end, and the receiving end may be a terminal device such as a mobile phone, a notebook computer, a handheld computer, or the like, or may be a control device such as a base station, a relay station, or the like.
