Description
Technical field
The present invention relates to the communications field, more particularly to a kind of data transmission method and system.
Background technology
With the fast development of wireless communication technique, limited frequency spectrum resource is increasingly becoming the master for restricting Development of Wireless Communications
Factor is wanted, but exactly limited frequency spectrum resource excites the appearance of new technology.Capacity and covering are two in a wireless communication system
A important performance indicator, in order to increase capacity, uses identical frequency process networking, but identical frequency process networking adds minizone again more
Interference, so as to cause covering performance to decline.
In Long Term Evolution (Long Term Evolution, LTE) system, downlink employs orthogonal frequency division multiplexing multiple access
(Orthogonal Frequency Division Multiplexing Access, the OFDMA) technology of access, can significantly drop
Interference in low cell, but use identical frequency process networking due to more, inter-cell interference (Inter-Cell Interference,
ICI) increase is obvious.In order to reduce ICI, LTE also has standardized many technologies, for example, downlink inter-cell interference cancellation (Inter-
Cell Interfernce Cancellation, ICIC).Downlink ICIC technologies are based on eNodeB Relative Narrowband TX Power
The method of (Relative Narrowband TX Power, RNTP) limitation realizes that downlink disturbs advance prompting function, enhances
The covering performance of physical down Traffic Channel (Physical Downlink Shared Channel, PDSCH).Uplink employs
He Single Carrier-Frequency Division multiple access accesses (Single Carrier-Frequency Division Multiplexing Access, SC-
FDMA) technology, can significantly reduce the peak-to-average force ratio of UE, improve signal quality, but due to using identical frequency process networking as much, it is small
Interference ICI increases in section are obvious.In order to reduce ICI, LTE uplinks also have standardized many technologies, for example, uplink is based on HII/OI
ICIC technologies, enhance physical uplink Traffic Channel (Physical Uplink Shared Channel, PUSCH).
In addition, multiple-input and multiple-output (Multiple Input Multiple Output, MIMO) technology passes through space point
Collection, spatial reuse and beam forming technique can also improve the covering performance and volumetric properties of LTE system, be particularly based on MIMO technology
Coordinate multipoint (Coordinated Multiple Point, the CoMP) technology to grow up.But due in current network, terminal
(User Equipment, UE) is that single antenna is sent, so, the improvement of MIMO technology and CoMP technologies for uplink is limited,
(Joint Receiver, JR), which can only be received, by the joint of receiving terminal is improved.
In addition, channel coding (Channel Coding) technology has significant contribution on link transmission performance is improved, make
The various declines of channel can be resisted by obtaining data.
Although there are the transmission performance that numerous technologies can improve system, especially network covering property in LTE system,
Confirmed by network test and software emulation, PDSCH and VoIP business when PUSCH during moderate rate, high-speed is still
It is the channel that covering performance is limited in each channel in LTE system.Itself main reason is that：The transmit power of UE is limited to be caused
PUSCH and VoIP etc. speed are limited, and the ICI between base station causes the PDSCH of high-speed to be limited.This covering to LTE system
Performance boost proposes demand, for this reason, LTE system introduce Transmission Time Interval (Transmission Time Interval,
TTI (Bundling) technology) is bundled.TTI Bundling technologies form different redundancies by channel coding to whole data packet
Version, different redundancy versions transmit in continuous TTI respectively, and TTI Bundling technologies are by taking more transmission moneys
Source, obtains coding gain and diversity gain, to obtain the reception energy of higher and link signal-to-noise ratio, so as to improve LTE system
Covering power.
Fig. 1 is that a kind of TTI Bundling of VoIP business in correlation technique transmit schematic diagram, as shown in Figure 1,4 continuous
TTI be referred to as TTI Bundling sizes (TTI Bundling Size) be 4 TTIBundling, TTIs of the UE in PUSCH
The first biographies of TTI Bundling are carried out on t to t+3, eNodeB is received after TTI Bundling head are passed in the downlink physical of TTI t+7
Hybrid automatic repeat-request (Hybrid Automatic Repeat Request, HARQ) instruction channel (Physical HARQ
Indication Channel, PHICH) on indicate HARQ response messages, if response is NACK (Non-Acknowledge),
Then UE will carry out the 2nd transmission (the i.e. first time of TTI Bundling of TTI Bundling on the TTI t+16 to 19 of PUSCH
Retransmit), eNodeB indicates HARQ responses letter after receiving the first time re-transmission of TTI Bundling on the PHICH of TTI t+24
Breath；And so on, until response is ACK (Acknowledge), or reaches allow maximum and attempted the number of transmissions (such as 3
It is secondary), transmission ending.The control information (such as resource location) of TTI Bundling passes through first TTI in TTI Bundling
Corresponding PDCCH instructions.
It is it should be noted that former using transmission of TTI Bundling transmission data (Data) business with transmitting VoIP business
Manage it is identical, its difference lies in, using TTI Bundling transmit VoIP business when, data sending have periodically, using TTI
During Bundling transmitting data services, data sending is without periodically.
Under scene shown in Fig. 1, the resource block number in each TTI in TTI Bundling is equal, although money
The equal control process that can simplify TTI Bundling of source block number, and the control overhead of TTI Bundling is reduced, but TTI
Resource block number in Bundling in each TTI is equal to cause problems with：The resource of each TTI Bundling transmission
Block number mesh is the resource block number * TTI Bundling sizes of each TTI, causes the transmission that can be transmitted in TTI Bundling
The value of block size (Transmission Block Size, TBS) is restricted, this is small for VoIP service impacts, because
The TBS of VoIP business has carried out targeted design, such as the full rate of TBS=328 corresponding A MR encoders under full rate,
RB numbers have setting from 1~9, but for data service, since its speed range is more wide in range, can be reached from 1kb/s
1Mb/s, it is necessary to TBS species it is more, so, when TTI Bundling are applied to data transfer, TBS selection flexibility
