For this pilot transmission mode, if a PRB only need transmit a customer traffic, then still according to above-mentioned definite sequence a corresponding to this PRB, recycle spreading code corresponding to this customer traffic sequence a is carried out spread spectrum, then the spread spectrum result is weighted with antenna weights corresponding to this customer traffic, utilize at last PORT6 and PORT7 transmission weighted results to get final product, the mode that concrete weighted results is mapped to PORT6 and PORT7 is identical with the amalgamation result mapping mode of above-mentioned introduction, just repeats no more here.

In the 4th kind of pilot frequency transmission method of the first kind, 8 couples of PORT6 and PORT7 are set, therefore, compare with first kind the first pilot frequency transmission method, it is more sparse that PORT6 and PORT7 arrange, and the RE number that takies has lacked 8, the resource of therefore having saved 8RE, correspondingly, pilot tone Overhead has also reduced.But because pilot settings is more sparse, therefore, the relative the first pilot frequency transmission method of channel estimating performance can reduce again.

The 3rd group comprises 3 couples of PORT6 and PORT7, and 3 PORT6 wherein all take the 11st OFDM symbol, and takies respectively the 3rd, 8,12 subcarrier; 3 PORT7 wherein all take the 11st OFDM symbol, and take respectively the 1st, 6,10 subcarrier.

Based on above-mentioned pilot tone port pattern, on the PRB of each transmission double user data flows, the pilot transmission of double user data flows can followingly be carried out:

A, systemic presupposition pilot frequency sequence S for different customer traffics, can adopt identical pilot frequency sequence S, perhaps can adopt different pilot frequency sequence S; More specifically, two data flow for same user can adopt identical pilot frequency sequence, and two data flow for different user can adopt different pilot frequency sequences, perhaps also can adopt identical pilot frequency sequence;

If system bandwidth has N PRB, then the S sequence is the sequence of N*10 * 1 dimension;

B, in two customer traffics each, take PRB as unit, from corresponding S sequence, extract the pilot frequency sequence a that 10 elements consist of this customer traffic, establishing m is the index of current PRB in N PRB, then the pilot frequency sequence of arbitrary customer traffic is a ^m, $\begin{array}{c}{a}_n^m\left(k\right)=S_n(m*3+k),k=\mathrm{0,1,2};m=0,...,N-1,n=\mathrm{1,2}\\ a_n^m(k+3)=S_n(3\·N+m*4+k),k=\mathrm{0,1,2,3};m=0,...,N-1,n=\mathrm{1,2};\\ a_n^m(k+7)=S_n(7\·N+m*3+k),k=\mathrm{0,1,2};m=0,...,N-1,n=1,2\end{array}$ Wherein, n is the index of customer traffic;

C, obtain two customer traffics, 10 * 1 dimension sequence a separately ₁ ^mAnd a ₂ ^mAfter, respectively to a ₁ ^mAnd a ₂ ^mTwo sequence weightings suppose that the weighted value of a transmitting antenna two streams on a PRB is respectively w ₁ ^mAnd w ₂ ^m, w ₁ ^mAnd w ₂ ^mBe scalar, the weighted value of different antennas can be different, then to a ₁ ^mAnd a ₂ ^mBe weighted respectively and be operating as $P{a}_1^m=a_1^m*w_1^m$ With $P{a}_2^m=a_2^m*w_2^m;$

D, for the sequence Pa after the weighting ₁ ^m, according to the order of time domain behind the first frequency domain, with this sequence P ₁ ^mIn each element, be mapped on each PORT6 of current PRB; For the sequence Pa after the weighting ₂ ^m, according to the order of time domain behind the first frequency domain, with this sequence Pa ₂ ^mIn each element, be mapped on each PORT7 of current PRB.As seen, this mapping mode is identical with the mapping in aforementioned Equations of The Second Kind the first pilot transmission mode, and just the line number of synthetic sequence matrix is different, and correspondingly, the logarithm of PORT6 and PORT7 is also different.

By the way, namely can realize the pilot tone of transmission double user data flows in PRB.With similarly aforementioned, the explanation of only carrying out as example take a PRB here.

For this pilot transmission mode, if a PRB only need transmit a customer traffic, then still determine in the manner described above the pilot frequency sequence a of this customer traffic on current PRB, then with antenna weights corresponding to this customer traffic, corresponding pilot frequency sequence is weighted, utilizes at last PORT6 and PORT7 transmission weighted results to get final product.

In Equations of The Second Kind the second pilot frequency transmission method, the 10 couples of PORT6 that arrange and PORT7, therefore, compare with first kind the first pilot frequency transmission method, it is more sparse that PORT6 and PORT7 arrange, and the RE number that takies has lacked 4, the resource of therefore having saved 4RE, correspondingly, pilot tone Overhead has also reduced.But because pilot settings is more sparse, therefore, channel estimating performance is relatively a bit weaker.

3, the third pilot frequency transmission method of Equations of The Second Kind

In the third pilot frequency transmission method of Equations of The Second Kind, in each PRB, 16 RE are set as 8 couples of PORT6 and PORT7, and 8 couples of PORT6 and PORT7 are divided into 2 groups, every group comprises 4 couples of PORT6 and PORT7.

Based on above-mentioned pilot tone port pattern, on the PRB of each transmission double user data flows, the pilot transmission of double user data flows can followingly be carried out:

A, systemic presupposition pilot frequency sequence S for different customer traffics, can adopt identical pilot frequency sequence S, perhaps can adopt different pilot frequency sequence S; More specifically, two data flow for same user can adopt identical pilot frequency sequence, and two data flow for different user can adopt different pilot frequency sequences, perhaps also can adopt identical pilot frequency sequence;

If system bandwidth has N PRB, then the S sequence is the sequence of N*8 * 1 dimension;

B, in two customer traffics each, take PRB as unit, from corresponding S sequence, extract the pilot frequency sequence a that 8 elements consist of this customer traffic, establishing m is the index of current PRB in N PRB, then the pilot frequency sequence of arbitrary customer traffic is a ^m, $a_n^m(k+4\·l)=S_n(4\·l\·N+m*4+k),$ L=0,1; K=0,1,2,3; M=0 ..., N-1, n=1,2; Wherein, n is the index of customer traffic;

C, obtain two customer traffics, 8 * 1 dimension sequence a separately ₁ ^mAnd a ₂ ^mAfter, respectively to a ₁ ^mAnd a ₂ ^mTwo sequence weightings suppose that the weighted value of a transmitting antenna two streams on a PRB is respectively w ₁ ^mAnd w ₂ ^m, w ₁ ^mAnd w ₂ ^mBe scalar, the weighted value of different antennas can be different, then to a ₁ ^mAnd a ₂ ^mBe weighted respectively and be operating as ${\mathrm{Pa}}_1^m=a_1^m*w_1^m$ With ${\mathrm{Pa}}_2^m=a_2^m*w_2^m;$

D, for the sequence Pa after the weighting ₁ ^m, according to the order of time domain behind the first frequency domain, with this sequence Pa ₁ ^mIn each element, be mapped on each PORT6 of current PRB; For the sequence Pa after the weighting ₂ ^m, according to the order of time domain behind the first frequency domain, with this sequence Pa ₂ ^mIn each element, be mapped on each PORT7 of current PRB.As seen, this mapping mode is identical with the mapping in aforementioned Equations of The Second Kind the first pilot transmission mode, and just the line number of synthetic sequence matrix is different, and correspondingly, the logarithm of PORT6 and PORT7 is also different.

By the way, namely can realize the pilot tone of transmission double user data flows in PRB.With similarly aforementioned, the explanation of only carrying out as example take a PRB here.

For this pilot transmission mode, if a PRB only need transmit a customer traffic, then still determine in the manner described above the pilot frequency sequence a of this customer traffic on current PRB, then with antenna weights corresponding to this customer traffic, corresponding pilot frequency sequence is weighted, utilizes at last PORT6 and PORT7 transmission weighted results to get final product.

In the third pilot frequency transmission method of Equations of The Second Kind, 8 couples of PORT6 and PORT7 are set, therefore, compare with first kind the first pilot frequency transmission method, it is more sparse that PORT6 and PORT7 arrange, and the RE number that takies has lacked 8, the resource of therefore having saved 8RE, correspondingly, pilot tone Overhead has also reduced.But because pilot settings is more sparse, therefore, the relative the first pilot frequency transmission method of channel estimating performance can reduce again.

With the similar ground of first kind pilot frequency transmission method, in actual applications, can between requiring, resource that pilot tone takies and channel estimating performance carry out balance, select suitable a kind of pilot number, carry out the pilot transmission of double user data flows.

In addition, consider for high speed and low-speed motion environment, system is for the difference of channel circumstance, can be under high speed and low-speed motion environment, utilize the RE of varying number to carry out the pilot transmission of double user data flows, particularly, under the high-speed motion environment, utilize more RE transmission pilot tone, thereby guarantee channel estimating performance; Under the low-speed motion environment, utilize less RE transmission pilot tone, thereby save the RE resource.

Particularly, can adopt the pilot tone pattern design shown in above-mentioned Fig. 5 a, Fig. 5 b, Fig. 5 c, Fig. 6 a and Fig. 6 b, based on this pilot tone pattern, be high speed or low speed according to system environments, selects suitable RE to carry out the transmission of double user data flows:

If two customer traffics are in the lower time of system environments of high-speed motion, utilize the pilot frequency sequence of upper all PORT6 that arrange of PRB and two customer traffics of PORT7 transmission; If two customer traffics are in the lower time of system environments of low-speed motion, utilize upper first group of arranging of PRB and the 3rd group PORT6 and the pilot frequency sequence of two customer traffics of PORT7 transmission.

The situation that specifically belongs to high-speed motion still belongs to the situation of low-speed motion, can indicate by a bit among the PDCCH of dispatched users.
