Step 101, to the pilot resources of the UE allocation space transmission number of plies and the transmission of each space transport layer.

Step 102, generates pilot resources information according to the pilot resources of amount of space transmission and the transmission of each space transport layer.

Particularly, according to one embodiment of present invention, pilot resources information comprises: the pilot resources of UE first space transport layer transmission in each space transport layer of distributing to this UE, with amount of space transmission, this first space transport layer can be numbered minimum space transport layer in the transport layer of each space.Or according to another embodiment of the invention, pilot resources information comprises the pilot resources of UE in the each space transport layer transmission distributing to this UE.Or according to still another embodiment of the invention, pilot resources information comprises the pilot resources of UE first space transport layer transmission in each space transport layer of distributing to this UE.In addition, the pilot resources information of the embodiment of the present invention is not limited to above several, as long as UE can determine according to this pilot resources information the pilot resources that UE uses.

In addition, the further embodiment according to the present invention, compared with the embodiment shown in Fig. 1, pilot resources information can also comprise that the current pilot resources of communication system uses state, this current pilot resources use state description communication system used at present how many Resource Units, altogether have according to communication system the Resource Unit quantity that a few part pilot resources and every a part of pilot resources comprise, UE can be known the possible pilot resources information of pairing UE, and the UE that wherein matches also uses the UE of identical running time-frequency resource.According to the pilot resources information of this pairing UE, just can estimate to match the channel estimation value of UE, thereby carry out input or disturb and suppress to detect, improve signal detection performance, and correctly obtain the Resource Unit of service data transmission, thereby correctly obtain the business datum of oneself from the Resource Unit of this service data transmission.

In addition, the further embodiment according to the present invention, compared with the embodiment shown in Fig. 1, pilot resources information can also comprise the use state of the pilot resources of the each space transport layer transmission distributing to this UE, for example: for code division multiplexing mode, the use state of this pilot resources can be the code word of pilot resources, or divide and added-time frequency division multiplexing mode for code, the use state of this pilot resources can be the code word of pilot resources and the time-frequency position that takies, so that UE obtains the channel estimation value of this UE use channel according to this code word and the data message receiving, and according to this channel estimation value, further obtain business datum.

Step 103, sends data message to UE, and this data message comprises pilot resources information.

Fig. 2 is the schematic diagram of a time/frequency source block, below taking the running time-frequency resource of communication system as the time/frequency source block shown in Fig. 2 is as example, the data sending processing method of the embodiment of the present invention is described.In Fig. 2, a subframe comprises 2 time slots: time slot 0 and time slot 1.In each time slot, have 7 OFDMs (Frequency Division Multiplexing, hereinafter to be referred as OFDM) symbol, total 12x7 Resource Unit (Resource element, hereinafter to be referred as: RE).In the Resource Block shown in Fig. 2, can adopt and distribute with the following method pilot resources: for the first RE201, in time domain, introduce code division multiplexing (Code Division Multiple, hereinafter to be referred as: CDM), can provide 4 orthogonal pilot resources.For example: adopt Walsh (Walsh) matrix of 4x4, formed by c1, c2, c3 and c4, wherein, and c1=[1,1,1,1], c2=[1 ,-1,1 ,-1], c3=[1,1 ,-1 ,-1] and, c4=[1 ,-1 ,-1,1].Adopt identical method, for the second RE202, also in time domain, introduce CDM, 4 orthogonal pilot resources can be provided.The use state of the pilot resources of the each space transport layer transmission distributing to this UE in this embodiment, is exactly specifically the code word of distributing pilot resources to UE.This code word can also be c1=[1,0,1,0], c2=[0,1,0,1], c3=[1,0 ,-1,0] and c4=[0,1,0 ,-1]; Or adopt the DFT transformation matrix of 4x4, formed by c1 ', c2 ', c3 ' and c4 ', wherein, c1 '=[1,1,1,1], c2 '=[1 ,-j ,-1, j], c3 '=[1 ,-1,1 ,-1], c4 '=[1, j ,-1 ,-j].The subset of code words that orthogonal length that length is 4 orthogonal code set-inclusion is 2, as the subset [1 of c1,1] with the subset [1 of c2,-1] be pair of orthogonal code word, c1 and c2 are that pair of orthogonal length is 2 code word, in like manner c3 and c4 are also that pair of orthogonal length is 2 code word, and c2 ' and c4 ' are also that pair of orthogonal length is 2 code word.When the upper orthogonal guide frequency that only need to transmit two transmission space layers of identical pilot resources RE, can in 4 orthogonal codes, select orthogonal length is that 2 code assignment is to two transmission space layers, as c1 and c2, or c3 and c4, or c1 ' and c3 ', or c2 ' and c4 '.In a time slot, the pilot tone of two transmission space layers is also orthogonal like this, can improve the performance of channel estimating in the high translational speed situation of UE.

In spatial reuse transmission, communication system is arranged the dedicated pilot resource of support space multiplexing transmission as shown in Figure 2.Suppose: on the first RE201, carry out respectively the pilot resources of mark the first space transport layer, second space transport layer, the 5th space transport layer and the 6th space transport layer with p1, p2, p5 and p6, its code word is respectively c1, c2, c3 and c4; On the second RE202, carry out respectively the pilot resources of mark the 3rd space transport layer, the 4th space transport layer, the 7th space transport layer and the 8th space transport layer with p3, p4, p7 and p8, its code word is respectively c1, c2, c3 and c4.

At Single User MIMO (Single user MIMO, hereinafter to be referred as: SU-MIMO) under pattern, adopt above-mentioned pilot resources to put in order, if amount of space transmission <=4, choose successively the corresponding pilot resources of p1～p4 according to amount of space transmission, higher throughput of transmissions can be provided.But, under MU-MIMO pattern, between pairing UE, thering is certain space isolation, it transmits and spatially has different directivity.

Suppose that a UE and the 2nd UE are for pairing UE.ENodeB distributes the pilot resources of a sheaf space transport layer and this space transport layer transmission to a UE, that is: amount of space transmission is that the pilot resources of 1, the first space transport layer transmission is p1; The pilot resources that distributes two sheaf space transport layers and transmit to each space transport layer of the 2nd UE distribution to the 2nd UE, that is: amount of space transmission is that the pilot resources of 2, the first space transport layers transmission is p3, communication system has been used 24 RE at present.The current pilot resources of the pilot resources that eNodeB transmits according to the amount of space transmission of distributing to a UE and each space transport layer of distributing to a UE and communication system uses state, generate pilot resources information, and this pilot resources information is carried at and in data message, sends to a UE.The current pilot resources of the pilot resources that eNodeB transmits according to the amount of space transmission of distributing to the 2nd UE and each space transport layer of distributing to the 2nd UE and communication system uses state, generate pilot resources information, and this pilot resources information is carried at and in data message, sends to the 2nd UE.

The one UE gets after pilot resources information from data message, according to pilot resources information wherein, known amount of space transmission of distributing to oneself is 1, the pilot resources of the first space transport layer transmission is p1, therefore known oneself pilot resources is p1, further, because communication system has been used 24 RE at present, even if also used up the first RE201 and the second RE202, known data transmission resources unit is the RE outside the first RE201 shown in Fig. 2 and the second RE202, therefore, the one UE just can be from this data transmission resources unit, correctly obtain the business datum that eNodeB sends to oneself.

Equally, the 2nd UE gets after pilot resources information from data message, according to pilot resources information wherein, known amount of space transmission of distributing to oneself is 2, the pilot resources of the first space transport layer transmission is p3, therefore known oneself pilot resources is p3 and p4, further, because communication system has been used 24 RE at present, even if also used up the first RE201 and the second RE202, known data transmission resources unit is the RE outside the first RE201 shown in Fig. 2 and the second RE202, therefore, the 2nd UE just can be from this data transmission resources unit, correctly obtain the business datum that eNodeB sends to oneself.

Under MU-MIMO pattern, communication system can only be used same RE, for example: only use the first RE201 or the second RE202, also can use two kinds of RE simultaneously.Therefore,, under MU-MIMO mode of operation, eNodeB and UE can arrange or notify the current pilot resources of UE to use state.Owing to thering is certain space isolation between multiple pairing UE, therefore, in pairing UE number <=4, total transmission number of plies <=4 o'clock of maximum transmitted number of plies <=2 of each UE and multiple pairing UE, communication system can consider that multiple pairing UE only use any RE, like this, when notify current pilot resources to use state to UE, just can send again the kind of the RE of use, reduce transinformation, also simplified the treating capacity of UE to information.

For example: use the first RE201 if eNodeB and UE make an appointment,, in above-mentioned example, use state just can not carry the current pilot resources of communication system in pilot resources information.The amount of space transmission that eNodeB distributes to a UE1 is that the pilot resources of 1, the first space transport layer transmission is p1; The amount of space transmission of distributing to the 2nd UE2 is that the pilot resources of 2, the first space transport layer transmission is p2.ENodeB generates pilot resources information according to the amount of space transmission of distributing to a UE and the pilot resources of the each space transport layer transmission distributing to a UE, and this pilot resources information is carried at and in data message, sends to a UE, generate pilot resources information according to the amount of space transmission of distributing to the 2nd UE and the pilot resources of the each space transport layer transmission distributing to the 2nd UE, and this pilot resources information is carried at and in data message, sends to the 2nd UE.The one UE receives and from data message, gets after pilot resources information, and according to pilot resources information wherein, known is that the pilot resources that 1, the first space transport layer is transmitted is p1 to own amount of space transmission of distributing, and therefore known oneself pilot resources is p1.The 2nd UE receives and from data message, gets after pilot resources information, according to pilot resources information wherein, known amount of space transmission of distributing to oneself is that the pilot resources of 2, the first space transport layers transmission is p2, and therefore known oneself pilot resources is p2 and p5.Further, because communication system is made an appointment and is used the first RE201, known data transmission resources unit is the RE outside the first RE201 shown in Fig. 2, therefore, the one UE and the 2nd UE just can be respectively from this data transmission resources unit, correctly obtain eNodeB and send to the business datum of oneself.

In addition, can also approximately fix in identical UE amount of space transmission situation, UE uses the code point orthogonal guide frequency resource of same pilot resource overhead under SU-MIMO and MU-MIMO transmission mode, wherein, pilot resources expense can be the number of the RE of UE use, and UE space transport layer is the space transport layer using in UE side in the space transport layer of base station assigns.As UE is less than or equal to 2 o'clock SU-MIMO and MU-MIMO all uses the first RE201 pilot resources in Fig. 2 in amount of space transmission, or SU-MIMO uses the first RE201 pilot resources, MU-MIMO uses the second RE202 pilot resources, or SU-MIMO uses the second RE202 pilot resources, MU-MIMO uses the first RE201 pilot resources, or SU-MIMO and MU-MIMO all use the second RE202 pilot resources.The benefit of agreement is like this: when only having in the Resource Block that the UE business datum under MU-MIMO pattern takies in part Resource Block while being SU-MIMO transmission for other Resource Block of MU-MIMO transmission, if the system pilot resource overhead that MU-MIMO is corresponding with SU-MIMO is different, as, the system pilot resource of SU-MIMO is 12 RE of the first RE201, and the system pilot resource of MU-MIMO is 24 RE of the first RE201 and the second RE202, it is the first RE201 and the second RE202 that system can only generate pilot resources information indicating user system pilot resource service condition according to maximum pilot resources expense, but reality in SU-MIMO transmission Resource Block in the second RE202 pilot resources do not used, therefore cause the wasting of resources.

In LTE+ communication system, in order to realize scheduling of resource more flexibly, can carry out the dynamic switching of SU-MIMO and MU-MIMO according to user's channel condition and power system capacity demand.NodeB can be clear and definite inform that UE current business transfer of data is in SU-MIMO or MU-MIMO, but by current pilot resources information, UE can be known current in SU-MIMO or MU-MIMO state.According to embodiments of the invention, the pilot tone RE that under the MU-MIMO pattern of can making an appointment, system is used; And, the further agreement pilot resources corresponding with user's the transmission space number of plies.According to these agreement relations, the pilot resources information that the user's who comprises in pilot resources information transmission space number of plies information, each transmission space layer are used, and system pilot resource using status information carries out combined signal source coding, thereby reduce information bit expense.

Still, taking Fig. 2 as example, in the first RE201 resource, pass through Walsh code c1=[1,1,1,1], c2=[1 ,-1,1 ,-1], c3=[1,1 ,-1 ,-1] and, c4=[1 ,-1 ,-1,1] can provide 4 codes to divide orthogonal pilot resources, be numbered P1, P2, P5, P6; Adopt identical method, for the second RE202, also can provide 4 codes to divide orthogonal pilot resources, be numbered P3, P4, P7, P8.Suppose under SU-MIMO transmission, the transmission space number of plies of UE can be 1～8 layer, the approximately settled UE transmission number of plies is to use pilot resources P1 at 1 o'clock, the UE transmission number of plies is to use pilot resources P1, P2 at 2 o'clock, the UE transmission number of plies is to use pilot resources P1, P2, P3 at 3 o'clock, the rest may be inferred, arrange unique pilot resources corresponding with the transmission space number of plies, under SU-MIMO pattern, the pilot resources that UE uses is the pilot resources that system sends, therefore in the time that the UE transmission space number of plies is less than or equal to 2, it is 2 orthogonal code that system pilot resource can be used orthogonal length; Under MU-MIMO transmission mode, transmission space number of plies <=2 of UE, carry out transmission space number of plies <=4 of the rear system of UE pairing, the pilot resources that agreement MU-MIMO uses is the first RE201, the UE transmission number of plies is to use pilot resources P1 or P2 or P5 or P6 at 1 o'clock, the UE transmission number of plies is to use pilot resources P1, P2 or P5, P6 at 2 o'clock, because UE under MU-MIMO pattern does not know the total number of plies of system transmission space, therefore system pilot resource comprises that all length is 4 orthogonal code.The pilot resources that UE can be transmitted to the number of plies, each transmission space layer pilot resources and the current use of communication system according to a preconcerted arrangement combines as shown in the table, and each combination is designated to pilot resources message sequence number, wherein the pilot resources of the corresponding SU-MIMO transmission mode of pilot resources message sequence number 0～7 distributes, and the pilot resources of the corresponding MU-MIMO transmission mode of sequence number 8～13 distributes.NodeB is according to UE transmission mode, the UE transmission space number of plies, according to making an appointment as UE distribution pilot resources, and corresponding pilot resources message sequence number is notified to UE, UE can be known the transmission space number of plies, the current pilot resources of the pilot resources that each transport layer is used and system uses state, and the pilot resources that uses of SU-MIMO according to a preconcerted arrangement and MU-MIMO is implicit has known current whether have other UE and its pairing.

In upper table, the current pilot resources use state of system comprises orthogonal (OCC:Orthogonal cover code) length of pilot resources RE position and code word, OCC=2 represents that code word is orthogonal in a slot, and OCC=4 represents that code word is orthogonal in a subframe.

In addition, the MU-MIMO transmission that the code word back-up system transmission space number of plies that can also be 2 based on orthogonal length is 2, i.e. two users, each user uses one deck transmission space.Going up table can also increase a pilot tone and combine corresponding MU-MIMO transmission mode, and in former form, to be labeled as pilot resources message sequence number be that 0 pilot tone combination also can be for MU-MIMO transmission mode.Form becomes:

It should be noted that, the MU-MIMO transmission of mentioning in the embodiment of the present invention is all carried out based on orthogonal guide frequency, be that the pilot tone that different user uses is orthogonal, if the MU-MIMO of system support based on nonopiate pilot tone, can use the pilot tone combination of corresponding SU-MIMO in above table, by being the different different pilot tone scrambler sequence of user assignment, realize MU-MIMO transmission, but the channel that UE cannot obtain pairing user by pilot tone disturbs inhibition detection.

The pilot resources of UE the transmission number of plies, each transmission space layer pilot resources and the current use of communication system combines the compound mode being not limited in above-mentioned two forms, the pilot resources that system can also be used according to other transmitting scene is set corresponding combination, for example, in the time carrying out data re-transmission, in order to reduce the complexity of data retransmission processing, set and retransmit and just pass and adopt identical system current pilot resource using status, or the combination of the pilot resources of other UE transformation parameter and each transmission space layer pilot resources and the current use of communication system, the numbering of combination can be set arbitrarily, meets combination and the mapping relations one by one of numbering, the current pilot resources of the pilot resources that each space transport layer is used and system uses state also can adopt other pilot resources, the pilot resources that 1 sheaf space transport layer corresponding to 0 pilot resources information use as being numbered in table is the P2 on RE 201, or the P3 on RE 202 etc., consider the power balance problem in different pilot tone RE resources, preferably set is to make the upper corresponding transmission number of plies of different frequency division pilot resources (RE201 and RE202) differ minimum, for example, user's transmission space number of plies is 6, should set 3 codes that use on RE201 divides 3 codes on orthogonal guide frequency and RE202 to divide orthogonal guide frequency, and do not adopt 4 codes on RE201 to divide 2 settings that code divides orthogonal guide frequency on orthogonal guide frequency and RE202.

In addition, can use state by the current pilot resources of communication system according to embodiments of the invention UE, for example: the pairing UE that makes an appointment uses any or which kind RE, know the pilot resources information of other pairing UE.For example: use the first RE201 if eNodeB and UE make an appointment, in above-mentioned example, known oneself the pilot resources of the one UE is p1, the pilot resources that may use of inferring the 2nd UE is p2, p5 and p6, like this, a UE is according to can, by detecting pilot resources p2, p5 and p6, estimating the channel estimation value of the 2nd UE, and according to the channel estimation value of the 2nd UE, carry out input or disturb and suppress to detect.Known oneself the pilot resources of the 2nd UE is p2 and p5, the pilot resources that may use of inferring a UE is p1 and p6, like this, the 2nd UE is according to passing through to detect pilot resources p1 and p6, estimate the channel estimation value of a UE, and according to the channel estimation value of a UE, carry out input or disturb and suppress to detect.

Fig. 3 is the schematic diagram of another time/frequency source block, compared with the time/frequency source block shown in Fig. 2, in time/frequency source block shown in Fig. 3, the one RE201, the 2nd RE202, the 3rd RE203 and the 4th RE204 pilot resources of corresponding the first space transport layer, second space transport layer, the 3rd space transport layer and the 4th space transport layer respectively, carry out mark with p1, p2, p3 and p4 respectively.

Suppose that a UE and the 2nd UE are for pairing UE.ENodeB distributes the pilot resources of a sheaf space transport layer and this space transport layer transmission to a UE, that is: amount of space transmission is that the pilot resources of 1, the first space transport layer transmission is p1; The pilot resources that distributes two sheaf space transport layers and transmit to each space transport layer of the 2nd UE distribution to the 2nd UE, that is: amount of space transmission is 2, the pilot resources of the first space transport layer transmission is p2, and the pilot resources that communication system is used is at present p1, p2 and p3.The current pilot resources of the pilot resources that eNodeB transmits according to the amount of space transmission of distributing to a UE and each space transport layer of distributing to a UE and communication system uses state, generate pilot resources information, and this pilot resources information is carried at and in data message, sends to a UE.The current pilot resources of the pilot resources that eNodeB transmits according to the amount of space transmission of distributing to the 2nd UE and each space transport layer of distributing to the 2nd UE and communication system uses state, generate pilot resources information, and this pilot resources information is carried at and in data message, sends to the 2nd UE.

The one UE gets after pilot resources information from data message, according to pilot resources information wherein, known amount of space transmission of distributing to oneself is 1, the pilot resources of the first space transport layer transmission is p1, therefore known oneself pilot resources is p1, further, the pilot resources using at present due to communication system is p1, p2 and p3, known data transmission resources unit is the first RE201 shown in Fig. 3, RE outside the second RE202 and the 3rd RE203, therefore, the one UE just can be from this data transmission resources unit, correctly obtain the business datum that eNodeB sends to oneself.Because known oneself the pilot resources of a UE is p1, the pilot resources that may use of inferring the 2nd UE is p2 and p3, like this, the one UE is according to passing through to detect pilot resources p2 and p3, estimate the channel estimation value of the 2nd UE, and according to the channel estimation value of the 2nd UE, carry out input or disturb and suppress to detect.

Equally, the 2nd UE gets after pilot resources information from data message, according to pilot resources information wherein, known amount of space transmission of distributing to oneself is 2, the pilot resources of the first space transport layer transmission is p2, therefore known oneself pilot resources is p2 and p3, further, the pilot resources using at present due to communication system is p1, p2 and p3, known data transmission resources unit is the first RE201 shown in Fig. 3, RE outside the second RE202 and the 3rd RE203, therefore, the 2nd UE just can be from this data transmission resources unit, correctly obtain the business datum that eNodeB sends to oneself.Because known oneself the pilot resources of the 2nd UE is p2 and p3, the pilot resources that may use of inferring a UE is p1, like this, the 2nd UE is according to passing through to detect pilot resources p1, estimate the channel estimation value of a UE, and according to the channel estimation value of a UE, carry out input or disturb and suppress to detect.

Fig. 4 is the flow chart of an embodiment of method for receiving and processing data of the present invention, and the flow process of this embodiment specifically can be realized by UE.As shown in Figure 4, this embodiment comprises the following steps:

Step 301, receiving data information, this data message comprises the pilot resources information of UE.

Step 302, determines the pilot resources of UE according to pilot resources information.

Particularly, the pilot resources information in step 301 can comprise: the pilot resources of UE first space transport layer transmission in each space transport layer of distributing to this UE, and with the amount of space transmission of distributing to this UE.Accordingly, in this step 302, according to pilot resources and the amount of space transmission of the first space transport layer transmission, this UE just can be known the pilot resources of oneself.Or the pilot resources information in step 301 can be also the pilot resources of UE in the each space transport layer transmission distributing to this UE,, in this step 302, can directly be known the pilot resources of UE by this pilot resources information.

Wherein, n is noise, respectively the coefficient of 4 composite channels, that is:

${\tilde{h}}_i=\left[\begin{array}{cccc}{h}_{11}& h_{12}& \&CenterDot;\&CenterDot;\&CenterDot;& h_{18}\end{array}\right]\left[\begin{array}{c}{w}_{1i}\\ w_{2i}\\ \&CenterDot;\\ \&CenterDot;\\ \&CenterDot;\\ w_{8i}\end{array}\right],i=1..4---\left(4\right)$

Further, by as shown in the formula (5), can obtain channel estimation value:

${\hat{h}}_1=\frac{1}{4}{\left(c_1\right)}^{H}y---\left(5\right)$
