Description
Technical field
The present invention relates to the communications field, relate more specifically to a kind of data transmission method and the data transmission system device of unifying.
Background technology
Traditional multicarrier modulation system is that high-speed data-flow is formed the data flow of a plurality of low speed by serial to parallel conversion, and then modulates corresponding carrier wave respectively, thereby constitutes the parallel transmission system that sends of a plurality of low-rate datas.But wherein a plurality of carrier waves that are used to modulate show as a plurality of overlapping the subcarrier of quadrature on frequency band.OFDM (OrthogonalFrequency Division Multiplexing, abbreviation OFDM) technology is a kind of special multi-carrier modulation technology, have between each subcarrier 1/2 overlapping, but at discrete Fourier transform (DFT) (Disperse Fourier Transform, being called for short DFT) maintenance is mutually orthogonal down in operation, receiving terminal can by the correlation demodulation technical point from, constitute data transmission system efficiently.The OFDM technology can improve spectrum efficiency greatly, utilize fast fourier transform (FastFourier Transfer simultaneously, be called for short FFT) and the hardware realization of inverse fast fourier transform (Inverse FastFourier Transfer is called for short IFFT), the realization of ofdm system can be simplified greatly.In addition, ofdm system can also utilize the Cyclic Prefix protection to reduce the intersymbol interference in front and back at interval, and can conveniently utilize frequency selectivity to resist the decline of wireless channel.Because the plurality of advantages of OFDM technology, the OFDM technology is widely used at present.Access scheme (OrthogonalFrequency Division Multiplexing Access based on orthogonal frequency division multiplexi, abbreviation OFDMA) system utilizes the OFDM technology to do multiplex technique, promptly by distributing different data subcarriers to distinguish different users to different user.Because transfer of data is used different mutually orthogonal subcarriers between the user, so transfer of data can the phase mutual interference between the user.And when subcarrier is distributed, can take into full account this user's wireless environment situation, make full use of frequency selectivity, distribute the data subcarrier of the most suitable transmission to the user, and, make power system capacity improve by the allocation schedule optimization Algorithm.
(Hybrid automatic Request withIncremental Redundancy is asked in mixing with steadily increase redundancy automatically, be called for short H-ARQ with IR) be a kind of link adaptation techniques, its basic process is: data sending terminal is encoded to information sets, encoded packets is divided into some fragments, and each transmission sends wherein one or more fragments.Data receiver is decoded to the encoded packets fragment that receives, if can not be correctly decoded, then feeds back to data sending terminal request repeat data.Data sending terminal then sends some fragments again, retransmitting the fragment that sends can be identical or different with the fragment that last time sent, data receiver is after receiving the fragment of re-transmission, when decoding, in conjunction with the encoded packets fragment of last time transmission and the encoded packets fragment of re-transmission, make full use of the relevant information that they carry, improve the decoding probability.The use of H-ARQ with IR technology has improved the error correcting capability of Data Receiving in the Radio Access Network, and can adapt to the variation of Radio Link automatically, thereby has improved transmission performance.
In wireless system based on the OFDMA technology, when wireless access terminal (Accessterminal is called for short AT) sends data to Radio Access Network when (Access network is called for short AN), AT determines the transmitting power of Traffic Channel and control channel according to the certain power control algolithm.The WiMAX that proposes such as QualCom company inserts in standard 802.20 systems, for the multiplexing OFDMA that all is based on of the transmission of data, during promptly each the transmission, distribute to the AT sub-carrier resources by AN, each AT uses the data subcarrier of distributing to oneself to carry out data-modulated and sends (reverse data transmission).In the same sector, each AT uses different sub-carrier resources, has guaranteed the orthogonality of transmission, makes that transfer of data can the phase mutual interference between the user.AN constantly adjusts the power of AT with reference to control channel by power control information, and AT determines the power of Traffic Channel by the certain power control algolithm then, and carries out the emission of Traffic Channel and control channel.Power control is the key technology that guarantees link transmission quality.But each AN is in the allocation of subcarriers resource, certain delay is all arranged, so AN does not also know the actual transmission power situation of AT constantly, the result just might cause at the real data x time, the power overload of AT, be the maximum transmit power limit that the power resource (the power sums that the channel of all emissions needs) of AT actual needs surpasses AT, AT will have to carry out power attenuation this moment, and the power attenuation of some channel is met the requirements with guaranteed output.
Oppositely, cover situations such as more weak owing to be in deep fading zone or travelling carriage apart from base station signal far away, travelling carriage will promote transmitting power to satisfy the received power level at receiving terminal, but when surpassing the travelling carriage maximum transmission power, travelling carriage need reduce the transmitting power on some subcarrier.
At forward direction, cover situations such as more weak owing to be in deep fading zone or travelling carriage apart from base station signal far away, base-station will promote the forward emitting power of this travelling carriage to satisfy the received power level at the travelling carriage receiving terminal, but surpass when the base station power amplifier is maximum to allow transmitting power, the transmitting power on some subcarrier need be reduced in the base station.
When emergent power transships, according to 802.20 agreements, AT will independently determine the priority of each channel, then according to the priority level of these channels, whether decision closes (gate-off) one or more of send channels, meet the demands with guaranteed output, promptly preferentially close the low channel of priority.In 802.20 systems, main backward channel comprises that R-CQI (is used to report the forward channel quality, if close emission, to cause very big influence to forward data transmission), (the affirmation channel of response forward data transmission is if close emission for R-ACKCH, to cause very big influence to forward data transmission), R-DCH (reverse data channel, if close emission, then reverse data can not transmit).Oppositely also there is some other control channel: such as R-REQCH (reverse Request channel, be mainly used in the reverse resource bid information that reports, as reverse buffer size, QoS priority etc., be used to carry out back scheduling), R-BFCH (reverse BeamForming channel, be used to report the relevant information of carrying out MIMO scheduling needs) or the like, but they all are to send in the cycle, priority is lower, and the power of these control channels itself is just very low, in power overload, even close emission, can significantly not reduce transmitting power yet.In reality system, the main cause of power overload is because scheduling the time is the too many sub-carrier resources of traffic channel assignments, and in actual transmissions constantly, the wireless environment of AT can not be supported so much sub-carrier resources, the result causes the data channel transmitting power too high, thereby makes the AT transmission power overload.So processing according to 802.20 agreements, when overload of reverse power, close channels transmit, or can impact forward data transmission, need close too many channel and could recover power, these operations all have a significant impact the stable and transmission performance of system.
Can find out that from above-described content the method for the power overload situation that occurs when handling wireless data transmission in the prior art can produce very big influence for the stability and the transmission performance of communication system.
Therefore, be necessary to improve existing service channel power damped system, with when emergent power when overload in the wireless data transmission process, can under situation the about stability and the transmission performance of communication system not produced a very large impact, realize normal transfer of data.

Wherein, the Traffic Channel perforation pattern specifically has following several:
1, regular pattern composite, i.e. the mode of making an appointment according to the data transmit-receive both sides, such as:
A. 1/2 resource is punched:, choose 0,2,4,6 subcarriers such as grade at OFDM symbol 1; At OFDM symbol 2, choose 1,3,5,7 subcarriers such as grade; At OFDM symbol 3, choose 0,2,4,6 subcarriers such as grade; At OFDM symbol 4, choose 1,3,5,7 subcarriers such as grade, the rest may be inferred;
B. 3/4 resource is punched:, choose 0,4,8,12 subcarriers such as grade at OFDM symbol 1; At OFDM symbol 2, choose 2,6,10,14 subcarriers such as grade; At OFDM symbol 3, choose 0,4,8,12 subcarriers such as grade; At OFDM symbol 4, choose 2,6,10,14 subcarriers such as grade; The rest may be inferred.
By the perforation pattern of design like this, can make full use of frequency diversity gain, i.e. the dispersed punching of frequency sub-carrier resource makes full use of the characteristics of frequency selectivity.
2: stochastic pattern, such as passing through to produce the m sequence of particular phases or other pseudo random sequence, each bit of sequence and a running time-frequency resource correspondence:
A. 1/2 resource is punched: bit is represented this resource for " 1 " and is kept, is perforated for " 0 " represents this resource;
B. 3/4 resource is punched: first " 1 " bit represents that this resource keeps, and second " 1 " bit represents that this resource is perforated, and the 3rd " 1 " bit represents that this resource is retained, and the like, " 0 " bit represents that this resource is perforated.
By the perforation pattern of design like this, can make full use of cell interference diversity gain, i.e. the effect of interference randomization.So punctured sequences needs the data transmit-receive both sides to determine, or both sides can both determine the punctured sequences that synchronization uses according to a certain rule.Such as the generation of sequence being followed sector mark, information such as time combine.
The running time-frequency resource perforation pattern is with two bit information bit representations.Possible Traffic Channel running time-frequency resource perforation pattern sends and receives both sides and need know that all this can consult mutually to determine by AN and AT.
When transmitting terminal punched to running time-frequency resource, receiving terminal must be known the pattern of punching, otherwise the noise of the position that is perforated will greatly disturb the demodulation code operations of receiving terminal.
So can design following running time-frequency resource perforation pattern information transmission mode, but be not limited to this method:
2bit information:
00: expression pattern 1;
01: expression pattern 2;
10: expression pattern 3;
11: expression pattern 4.
Four symbols can be designed to 4 points on the complex plane: 3 equidistant points on the center of circle and the unit circle.For example:
Transmitted 00 o'clock: power is 0, is equivalent to not send any traffic channel signal;
Transmitted 01 o'clock: sending symbol is 1, and power is very low with respect to Traffic Channel, for example is-20dB;
Transmitted 10 o'clock: sending symbol is
Power is very low with respect to Traffic Channel, for example is-20dB;
Transmitted 11 o'clock: sending symbol is
Power is very low with respect to Traffic Channel, for example is-20dB;
This symbol generates the modulation signal on the running time-frequency resource through certain scrambler sequence scrambling, and wherein, the scrambler sequence of this scrambler sequence and traffic channel symbols is low relevant.
The operating process of transmitting terminal is as follows:
Transmitting terminal is judged the transmitting power situation that exceeds standard, and selects one of four kinds of hole knockouts, and the encoded packets fragment is launched with the running time-frequency resource that is not perforated, and finishes a HARQ transmission.The encoded packets fragment is identical under time-frequency resource mapping and the normal mode of operation, and running time-frequency resource is perforated and only has influence on the coded identification number that each HARQ transmits.In the transmitting business channel, distributing to (all running time-frequency resources that comprise punching and be not perforated) transmission running time-frequency resource perforation pattern information on all running time-frequency resources of Traffic Channel.Running time-frequency resource perforation pattern information channel and Traffic Channel be actual to have constituted code division multiplexing.
The operating process of receiving terminal is as follows:
Receiving terminal when whenever receiving the signal of a HARQ transmission, demodulation running time-frequency resource perforation pattern information channel at first, demodulation Traffic Channel then.Its concrete steps are as follows:
1, uses the OFDM demodulation operation that the signal on the running time-frequency resource that receives is recovered, and carry out channel equalization with the result of channel estimating;
2, carry out descrambling with the signal of running time-frequency resource perforation pattern information channel scrambler sequence after to channel equalization, utilize behind the descrambling distance metric of four symbolic points on the data and complex plane, utilization Viterbi algorithm carries out the maximum likelihood decoding operation, obtains the running time-frequency resource perforation pattern of this time HARQ transmission;
3, on the basis of step 2, carry out interference eliminated, reduce the interference that Traffic Channel is subjected to, with the Traffic Channel scrambler sequence signal after the process interference eliminated is carried out descrambling then, the perforation pattern that utilizes step 2 to obtain is then separated mediation HARQ IR decode operation normally.
Because the speed that running time-frequency resource perforation pattern information channel transmits is very low, so its power ratio with respect to Traffic Channel can be very low, so can ignore the interference of Traffic Channel.Simultaneously, the high spread processing gain of code division multiplexing makes running time-frequency resource perforation pattern information channel still can obtain enough good demodulation performance.And the design of this code division multiplexing is expanded easily with the transmission more information, and Traffic Channel is kept transparent.
From above-mentioned steps as can be seen, utilize running time-frequency resource hole knockout and HARQ IR operation to can be good at seamless combination, to the HARQ operation transparent.
The front is by the agency of, in the reverse data transmission course of OFDMA system, power overload is owing to distribute too many subcarrier mostly, by the present invention, to some subcarrier emission carrying out gate-off, can guarantee can not launched with normal power by the sub-carrier resources of gate-off, the power of AT remains on normal condition simultaneously.Simultaneously, in existing wireless access system, in data transmission procedure, all used the HARQ technology, retransmitted and channel-decoding, also can guarantee the correctness of transfer of data by HARQ.Also can close simultaneously the emission of other control channels, so just can not cause too much influence the transmission of forward data.Wherein, about the selection of perforation pattern, situation that need to consider current actual power overload is judged and is chosen only perforation pattern.
In sum, in wireless data transmission process, when overload appears in power,, the running time-frequency resource that is perforated is carried out gate-off, reach the purpose of power attenuation by choosing certain running time-frequency resource perforation pattern based on OFDMA.Interference to the Traffic Channel normal transmission can be ignored, and can with the good seamless combination of HARQ-IR, to the HARQ operation transparent, HARQ operation is not had influence.The invention solves the problem of the normal transmission data under the power overload situation in the wireless data transmission process, thereby improved the stability and the transmission performance of communication system.
