Description

Communication device, method and system

The present invention relates to the communications field, more particularly to communication equipment, method and system for a kind of communication equipment, method and system technical field.Background technology has some scenes to propose more strict requirements to covering in following radio communication, in particular for some arrangements indoors or basement machine to machine（Machine to Machine, M2M) terminal.In order to lift the covering of wireless signal, at present generally using following a few class methods：Lifting transmission power, reduction code rate are merged with order of modulation, using relaying class technology, multiple send.

Maximum transmission power is limited, fading channel is very big and can not arrange in the scene of relay station, sending node carries out multiplicating transmission to a certain frame data of transmission, and receiving node repeatedly receives merging, the accuracy of decoding can be improved to a certain extent.But it is repeated several times and sends and can propose some requirements to some designs, especially for some broadcast messages, such as system information block (sys tem informat ion block, SIB), ensure that all or most of user can be properly received if desired, the number of times repeated will be very huge, and the efficiency that the preferable terminal of part covering is received is relatively low, and these terminals can only wait the arrival of follow-up data after receiving successfully quickly.Still further aspect, if SIB has thousand, once channel is in deep fade within a period of time, wherein some SIB reception failure can be caused, then this partial information can only wait next cycle to receive, or even cause whole system information reception failure.

Fig. 1 is shown in modulating-coding（Modulat ion and Coding Scheme, MCS) scheme uses regular coding speed, a kind of and situation without merging.It is so-called to refer to retransmit in hybrid automatic request without merging（Hybr id Automat ic Repeat reQues t, HARQ) during, to protocol Data Unit（Protocol Data Uni t, PDU) decoded packet data is unsuccessful, the situation abandoned.In a machine type communication (Machine Type Communicat ion MTC) subframe, a MTC subframe lengths are a traditional Long Term Evolution（Long Term Evolut ion, LTE) 8 times of subframe lengths.In the prior art in the scheme for being repeated several times and sending is realized, within the MTC subframes of a regular length, sending node is for a packet x_tRepeatedly sent, to improve the probability that receiving node is properly received.

For receiving node, not all receiving node is required for the repetition transmission of whole number of times in a MTC subframe to obtain required data.When the channel conditions of receiving node are relatively good, it is only necessary to which required data can be successfully obtained by receiving traditional LTE subframes of half in a MTC subframe.In the above case said, reference picture 2, receiving node, which only needs to receive 4 times, can successfully obtain required data.In this case, half subframe in addition can transmit other data.Such as Shown in Fig. 2, packet ^ is transmitted 4 times in the half of MTC subframes, other packet x₂Transmitted 4 times in the later half of MTC subframes.

But, there is the problem of being difficult to overcome in actual applications in such scheme.

Following situation is there may be during actual transmissions.As shown in figure 3, comprising 8 packets in a MTC subframe, the length of each packet is the length of tradition LTE subframes.Preceding 4 packets repeat transmission x t according to bag, and rear 4 packets repeat transmission x₂Packet.Because channel degradation or other reasonses cause in x₂Transmitting procedure in there is the situation of loss of data.As shown in figure 3, showing the packet of loss, i.e., the 6th, 8 data-bag losts with oblique line.Such case may influence x₂Be properly received.Fig. 4 show a case that it is more extreme, when the 5-8 packet is all lost, on x₂Packet all lose.Receiving node can not be received on x₂Any message of packet.It can be seen that such scheme is very sensitive to the position of error in data, it is unfavorable for the correct transmission of data.

It can thus be seen that in the prior art, the efficiency of transmission for the scheme that M2M terminals have in the data transmission is low, position sensing of some schemes to data.The content of the invention to provide higher efficiency of transmission, and reduces the dependence to Data Position the embodiments of the invention provide a kind of data processing method, communication equipment and system.

It can apply to repeat all scenes of transmission The embodiment provides a kind of data processing method.The design of the present invention is not limited under MTC scene, can also other scenes.For example, also there is the situation transmitted to Data duplication during broadcast communication, those skilled in the art only need to be adjusted the length and relevant parameter of each packet, you can use the technical scheme used in the embodiment of the present invention.

As a kind of embodiment of the present invention, Fig. 5 shows a kind of scene of MTC subframes.Multiple packets are included in one MTC subframe.The quantity of the packet, agreement or make an appointment can be adjusted according to used in communication equipment, such as can be natural number, and the natural number is more than or equal to 2.It is appreciated that in different application scenarios, MTC subframes can be other kinds of frame, as long as the frame comprising multiple packets can be using design of the invention.In the present embodiment, 8 packets are included in a MTC subframe.One MTC subframe lengths is 8 times of a LTE subframe lengths, i.e., the length of one packet and the equal length of LTE subframes.Compared to the technical scheme in background technology, the packet of each LTE sub-frame transmissions is no longer original packet in the present embodiment_XlOr x₂.But raw data packets χ₂Linear combination bag.Each linear combination bag is designated as y respectively_t、 y₂ y₈。

( 1 )

Wherein, k M ₂] it is coefficient vector.The quantity of the coefficient vector agreement or make an appointment can be configured according to used in communication equipment, such as can be natural number.In the present embodiment, at one In MTC subframes, the raw data packets of transmission are 2, and linear combination bag is 8, and correspondence is 8 using the coefficient vector.Each linear combination bag is the linear combination about 2 raw data packets.Each linear combination includes 2 components using a coefficient vector, each coefficient vector.It should be noted that disturbing in order to avoid thousand, any two of which coefficient vector all linear independences.Sending node and receiving node can predict these coefficient vectors in advance.For example, the 4th linear combination bag 7₄Used coefficient vector is to set in advance in advance, and sending node and receiving node all know that the 4th coefficient vector used in linear combination bag is [A L certainly₂ ] ₀In the present embodiment, as long as receiving node can be properly received at least two linear combination bags, as long as proper reception of 7_{1 8}In at least two, you can recover raw data packets X^ X₂。

Assuming that receiving correct y₂, i.e.,

Because have received y^ y₂It is first and second linear combination bags, it is possible to determine first vector [4₂] and

( A '

Second vector [A B₂], so the component of each in matrix is also known.For receiving node-

The Qe of B, B. 2

In formula（2) in, only_Xl、 x₂It is unknown.So, receiving node by calculate following formula can just recover raw data packets Xi and X2 come.X2 Qe ... ( 3 )

Wherein-l represents inverse matrix.

Calculate raw data packets Xi and χ₂Corresponding first linear combination bag coefficient of utilization vector 4], calculate second linear combination bag y₂Coefficient of utilization vector [A B₂ ] ₀Change another set raw data packets into_Xl, and χ₂' when, above-mentioned computational methods are still set up.Calculate corresponding first linear combination bag_yi, coefficient of utilization vector [A₂], calculate second linear combination bag y₂, coefficient of utilization vector [A B₂ ] ₀

Embodiment shown in Fig. 5 has the following advantages that：For the scheme of above-mentioned two raw data packets of transmission, each raw data packets are dispersed in multiple linear combination bags, so receiving node only needs to be properly received two linear combination bags, it is obtained with raw data packets, and the position of the two linear combination bags can be arbitrary, which reduces the dependence to Data Position, the channel situation of acute variation can be tackled, so that improve transmitting-receiving node anti-thousand disturb ability.Obvious this transmission means can improve efficiency of transmission compared to the scheme shown in Fig. 1, compared to the scheme shown in Fig. 3, then while efficiency of transmission is ensured, additionally it is possible to reduce probability of failure.

Above with two raw data packets x₂Exemplified by illustrate embodiments of the invention, below illustrate according to of the invention real Apply the situation of the more raw data packets of use of example.

Sending node can select appropriate number of raw data packets to calculate linear combination bag according to the channel quality between receiving node.The standard of selection can be determined according to channel condition.Generally, sending node obtains channel quality by detecting relevant parameter.Such as, signal to noise ratio is more than or equal to predetermined threshold, or pre-coding matrix instruction（Precoding Matrix Indicator, PMI) it is more than or equal to predetermined threshold, or channel quality is indicated（Channel Quality Indicator, CQI) be more than or equal to predetermined threshold when, channel quality is preferable；It is on the contrary then think that channel quality is poor.When channel quality is preferable, more raw data packets can be sent；When channel quality is bad, less raw data packets can be sent.For example, sending node find channel quality between receiving node it is relatively good when, Xi can be designated as using 3 raw data packets>Then similarly there is equation below：

- .. (4) wherein, 4 4], [^{βι β}2 ^l'---'^^{1 Η}2 ^³], it is coefficient vector, it should be noted that disturb in order to avoid thousand, wherein any three coefficient vectors all linear independences.In the present embodiment, sending node and receiving node know above-mentioned 8 coefficient vectors, the coefficient vector according to corresponding to the positional information of the linear combination bag received knows the linear combination bag.For receiving node, in formula（4) in, only_Xl、 χ₂、 χ₃It is unknown.So, as long as receiving node can be properly received at least three linear combination bags, as long as proper reception of 7_{1 8}In at least three, you can recover raw data packets Xi, x₂, X30 is for using the raw data packets χ Γ χ of 4₄, or greater number of raw data packets technical scheme, the rest may be inferred, repeats no more.

By adjusting the quantity of raw data packets in each linear combination bag, transmission rate can be adjusted.Include more raw data packets in same linear combination packet, anti-thousand abilities of disturbing of this transmission means can be than relatively low, but can significantly increase transmission rate；On the contrary, using less packet, transmission rate meeting relative reduction, but anti-thousand can be increased and disturb ability.So as to, when selecting raw data packets quantity, ability both sides demand can be disturbed according to transmission rate and anti-thousand and is selected, thus this selective power improves the adaptability of transmission plan.

In embodiment shown in Fig. 5, when the length of a MTC subframe is fixed, the quantity Μ of linear combination bag in each MTC subframes, the quantity Ν of raw data packets in each linear combination bag, and the coefficient vector of each linear combination bag present position, all it is known for sending node and receiving node.The Μ is less than or equal to the data packet number Υ that can be transmitted in a frame, any Ν linear independence in the Μ coefficient vector, component in each coefficient vector is Ν, the Υ, and Μ is the natural number more than or equal to 2.

Embodiment illustrated in fig. 14 is similar with embodiment illustrated in fig. 5, and the main distinction is：The quantity of the linear combination bag of generation is reduced, each linear combination bag is at least repeated to send once.

Assuming that transmission raw data packets are_XlAnd χ₂ , γ γ₄For combination and χ₂Linear combination bag, y " y₄Value with reference to public Formula（ 1 ).According to the present embodiment, as shown in figure 14, each linear combination bag repeats to send 1 time.I.e._YlIt has been repeatedly transmitted 2 times, y₂It has been repeatedly transmitted 2 times ... ..., y₄It has been repeatedly transmitted 2 times.Certainly, the mode that each linear combination bag is repeatedly transmitted can be determined according to channel situation.Such as 7₁3 times, y can be repeatedly transmitted₂It has been repeatedly transmitted 3 times, y₃It has sent 1 time, 7₄It has sent 1 time.Each linear combination bag can be continuously repeated transmission or discontinuously be repeatedly transmitted, such as y₂Linear combination bag can be sent the 3rd, in 5 linear combination bags.

The number of times that linear combination bag is repeatedly transmitted can be determined according to the complexity of required calculating.Using the coefficient vector repeated can reduce used in coefficient vector quantity, corresponding, communication equipment can just be omitted for the calculating of same factor vector, thus the amount of calculation of communication equipment tails off.So the embodiment shown in Figure 14 is in addition to the advantage for possessing embodiment illustrated in fig. 5, the requirement to communication equipment can also be further reduced.

Figure 16 shows that according to another embodiment of the present invention, essentially identical with embodiment shown in Fig. 5, the main distinction is：

In the present embodiment, used coefficient vector [4 l [ ₂] it is unfixed, can at random it be taken within the specific limits according to predetermined probability distribution.The collection of all coefficient vectors that can be used is combined into coefficient vector pond, and [4 M Bi l ---^ Ζ are set to here₂It should be noted that the quantity of the coefficient vector in this example in coefficient vector pond can be multiple, and 8 are not limited to, as long as the coefficient vector pond of communicating pair is consistent.It should be noted that the quantity of the component of each coefficient vector can be multiple, 2 are not limited in, it is equal generally with transmitting the quantity of the raw data packets used.

Sending node, randomly chooses at least one coefficient vector to carry out linear combination operation according to predetermined probability distribution from these coefficient vectors.The predetermined probability distribution can be to hook distribution or be uneven distribution.

For example, the selected probability of the coefficient vector of each in being uniformly distributed is equal, than if any ρ coefficient vector, then the selected probability of each coefficient vector is 1/ρ.So-called uneven distribution, refers to that the selected probability of the coefficient vector that may be used is not all equal.

A kind of example of the probability distribution of uneven distribution illustrated below.Include Ν component in one coefficient vector.Might have 1 in this Ν component-it is N number of be not 0.The coefficient vector that there is component by 0 is less and more for 0 component number not for the amount of calculation needed for 0 coefficient vector compared to important, and required amount of calculation is fewer, more should preferentially be used.So the quantity that component is 0 in coefficient vector is associated with selected probability.It can pre-set that the number containing 0 component is more, selected probability is bigger.It can for example set as follows：The Probability p i for having the coefficient vector that 1 component is 0 selected is not more than the Probability p 2 for having the coefficient vector that 1 component is 0 selected.By that analogy, there is the selected Probability p of the coefficient vector of N-2 0 components_N-₂No more than there is the selected probability P of the coefficient vector that N-1 component is 0 generally, the coefficient vector that N number of component is all 0 will not be selected.According to the property of probability, each coefficient to The selected probability non-negative of amount, and the summation of the selected probability of all coefficient vectors that can be used is 1.

By taking N=3 as an example.Assuming that each component can only take 0 or 1, then the situation that the number that component is 0 is 0 is 111, and the situation that the number that component is 0 is 1 is 110,101,011, and the situation that the number that component is 0 is 2 is 001,010,100.The situation that component is all 0 is 000, generally inapplicable.So, one has 7 coefficient vectors that can be used.Pre-set as follows：The selected probability that the number that component is 0 is 0 is 1/14, and the selected probability that the number that component is 0 is 1 is 5/14, and the selected probability that the number that component is 0 is 1 is 4/7.All 7 coefficient vector the probability that can be used and be 1.For each coefficient vector, selected probability is not all the same.Such as 111 selected probability are that 1/14,011 selected probability is 5/ (14*3), and 001 selected probability is 4/ (7*3).

Sending node can carry identification information in the linear combination bag of transmission.The identification information can be coefficient vector in itself or coefficient vector mark.If the information is the mark of coefficient vector, sending node and receiving node need to know coefficient vector and the mapping relations of mark.Tabled look-up by the mark or similar procedure, receiving node can determine that the sending node sends coefficient vector used in linear combination bag, and receiving node recovers raw data packets according to the coefficient vector.If sending node is in need, the processes such as similar lookup can also be carried out by the mark, to know that the sending node sends coefficient vector used in linear combination bag.It should be understood that coefficient vector can be preset with the mapping relations identified, it is possible to be omitted in transmission process.Each linear combination bag includes packet header and data two parts.Identification information can be placed on the header part of the linear combination bag, can also be placed on the other parts of the linear combination bag.Packet header can also carry other information except carrying identification information.

In the example shown in Figure 16, coefficient vector is placed on to the header part of linear combination bag.Calculate linear combination bag y₂Used coefficient vector is respectively 4] and it is individually positioned in 7 and y₂The header part of the two linear combination bags.

Or, the coefficient vector in coefficient vector pond is numbered, the mark of coefficient vector is used as.In transmission process, it is only necessary to the mark of corresponding coefficient vector is sent into receiving node, the transmission of data volume can be so reduced.As shown in figure 17, the mark of coefficient vector is placed on the header part of linear combination bag.Calculate linear combination bag y₂Used coefficient vector is respectively [4 A₂] and [A B₂], its corresponding mark is respectively that i and j, mark i and j are placed on and y respectively₂Header part.

Here any N number of linear independence in the M coefficient vector is explained.Assuming that N=3, M=4 here, that is, there are 3 raw data packets, 4 different coefficient vectors take 4 coefficient vectors to be： al= ( 0, 0, 1 ), a2= ( 0, 1, 0), a3= ( 1, 0, 0 ), a4= ( 1, 1, 1 ).Obviously there is al+a2+a3=a4, so 4 coefficient vectors are linear correlations.But wherein any 3 are linear independences, so 4 so taken out coefficient vector a l_a 4 can be used.

Among embodiment shown in Figure 16 and Figure 17, M coefficient vector is included in coefficient vector pond.When receiving node is correct When receiving N number of linear combination bag, if this N number of coefficient vector linear independence, N number of raw data packets can be recovered.If during N number of linear combination bag that receiving node is received, this N number of coefficient vector linear correlation can not then recover raw data packets.Receiving node needs to receive more linear combination bags.Only when there is N number of linear combination bag in all linear combination bags received, this N number of coefficient vector linear independence can just recover N number of raw data packets.

In the embodiment of the coefficient vector used at random, used coefficient vector is determined by sending node every time, is not required to decide through consultation in advance with receiving node.Possible coefficient vector used every time is all different in implementation process, more flexibly.Sending node and receiving node can choose suitable random coefficient vector according to channel condition, thus can further improve the adaptability of communication equipment at different conditions.

Another embodiment of the present invention, similar with the embodiment shown in Fig. 5, the main distinction is：

First, raw data packets x in the present embodiment_nLinear combination bag y is no longer obtained by linear combination mode_n, but nonlinear combination bag z is obtained by nonlinear combination mode_n。

Second, nonlinear combination mode.Sending node obtains nonlinear combination bag using a kind of nonlinear combinational means from raw data packets, and receiving node can obtain raw data packets using identical combined method from nonlinear combination bag.

On this basis, sending node and receiving node are fixed to the combined method of packet,, then need not be with any information related to combined method in the nonlinear combination bag in transmit process and receiving node knows combined method used in sending node in advance；If combined method, which has been used, needs the band information related to combined method in random algorithm, nonlinear combination bag, similarly, than if desired for carrying the corresponding mark of combined method.

Generally nonlinear combination bag is calculated by the way of nonlinear function.Nonlinear combination bag 2 can be：

Wherein, (^^₂) ,=1,2 ... it is nonlinear function. x₂For raw data packets.Inverse operation is carried out according to corresponding function characteristic, the value of raw data packets can be solved.The mode of concrete operation will be determined according to the characteristics of function itself.

The corresponding mark of combined method can also be used, the numbering of combined method is such as represented into used combination as mark.Its specific implementation is similar with the embodiment shown in Figure 17, repeats no more.

In order to notify it is linear combination mode or nonlinear combination mode used in receiving node sending node, can by indicate message indicate used in combination.

The possible nonlinear embodiment of one kind introduced below.The nonlinear combination bag ∑ can be： z₈ = H_xx_x + H₂x₂... (6) are for formula（6) for, the embodiment that linear is combined in embodiments of the invention can be used to obtain² , χ₂ ², and then obtain x_{l 5} x₂.For raw data packets x_{l 5} x₂For, combination bag is nonlinear.

Corresponding combined method can be selected for different channel conditions using nonlinear combination mode, the processing to packet is more flexible, can further improve the adaptability of communication equipment at different conditions.

Embodiments of the invention can be applied to many different occasions.For M2M occasion, usual M2M terminals can only support limited code modulation mode.Thus when channel situation acute variation, the limited code modulation mode that M2M terminals are supported can not adapt to more complicated signal intelligence.Particularly when the code modulation mode that M2M terminals are supported is mismatched with channel situation, the inefficiency of actual transmissions can be caused, and the probability of bust this increases.Embodiments of the invention can apply to M2M terminals, when the code modulation mode that M2M terminals are supported is mismatched with channel situation,, just being capable of match channels by adjusting linear combination mode or nonlinear combination mode M2M terminals in the case where modulation coding mode need not be adjusted.Thus improve the success rate of transmission.

It is different with Υ value by above-mentioned numerical value Ν, Μ, following several situations can be divided into.

1) when the number Μ of the coefficient vector is equal to the data packet number Υ that can be transmitted in one frame, described Υ combination bag is sent to opposite end communication node by the communication node by the frame.

Situation Μ=8, Υ=8 as shown in Figure 5, then sending node by 8 combination wrap 7₈Receiving node is sent to by the frame.
