Description

Information transmission method, terminal and base station
Technical Field
The present invention relates to the field of communications, and in particular, to an information transmission method, a terminal and a base station.
Background
In the related art wireless communication system, the transmitting end and the receiving end generally use multiple antennas for transmitting and receiving to obtain a higher rate. One principle of the multiple-input-multiple-output (MIMO) technology is to utilize some characteristics of a channel to form a multi-layer transmission matching characteristics of the channel, so as to effectively improve system performance, obtain significant performance improvement without increasing bandwidth and power, and be a very promising technology, which is widely applied in current systems. For example, in Long Term Evolution (Long Term Evolution, LTE for short) and its enhanced version systems, there are multiple schemes for multi-antenna technology transmission. Among these transmission schemes, some transmission schemes require a user to feed back a Precoding Matrix Indicator (PMI) and are called closed-loop MIMO techniques, and some transmission schemes do not require a Precoding Matrix Indicator (PMI) and are called open-loop MIMO techniques. In addition, in various transmission schemes of multiple multi-antenna technologies, diversity transmission has high reliability and less dependence on Channel State Information (CSI) feedback, and has received wide attention.
In the diversity technique in the related art, multi-antenna diversity transmission is mostly realized by an open loop mannerI.e. no CSI feedback needs to be relied upon to transmit data. Such as LD-CDD technology and SFBC technology based on CRS ports. In LTE Rel-14, a semi-open loop technique based on DMRS ports is introduced. In summary, the base station virtualizes a plurality of antenna ports to a small number of DMRS ports according to the long-term PMI information based on partial CSI information, for example, long-term PMI information, which is fed back from the terminal, and performs semi-open loop transmission. In particular, DMRS-based open loop/semi-open loop schemes include transparent and non-transparent transmission schemes. In a transparent transmission scheme, a Demodulation Reference Signal (DMRS) used for demodulating data and associated data transmission use the same precoding, for example, a LD-CDD technique, a Resource Block (RB) level precoding polling technique. In the RB-level precoding polling technique, a base station uses precoding obtained from a long-term PMI in turn on a plurality of RBs according to long-term PMI information fed back by a terminal, to acquire diversity gain. In non-transparent transmission schemes, DMRS and associated data transmission use different precoding. For the non-transparent diversity transmission scheme with rank 1, the typical methods are Space frequency Block Code (SFDC) and RE-level precoding polling with rank 1. Wherein SFBC is a more typical diversity transmission method, fig. 1 is a schematic diagram of a typical diversity transmission method in the related art, and as shown in fig. 1, 2 modulation symbols are transmitted on 2 REs and 2 DMRS ports on the same OFDM symbol. SFBC does not need to use CSI, and can orthogonalize channels on two Resource elements (REs for short) to achieve better hierarchical gain. In the SFBC scheme in the related art, paired REs are not optimized, and adjacent 2 REs are generally used for SFBC. Another non-transparent rank 1 transmission scheme is RE-level pre-coded polling with rank 1. In this scheme, precoding is polled on REs based on long-term PMI information fed back by the terminal, and the precoding used is a precoding vector with rank 1, e.g., the precoding vectors are polled on multiple REs on two DMRS ports

Figure BDA0001254482440000022
So as to capture the rapid change of the channel phase difference in the two polarization directions and obtain the grading gain.
In the above scheme, the non-transparent diversity transmission can achieve better performance because it can perform sufficient pre-coding polling at the RE level without sacrificing the channel estimation accuracy.
Specifically, because the precoding matrices used by the DMRS and the data are different, the interference correlation matrix calculated by the DMRS cannot represent the interference correlation matrix of actual data transmission, and when the terminal receives the data, the terminal cannot obtain a more accurate interference correlation matrix, and if an MMSE-IRC receiver is used, the performance of data transmission may be seriously affected.
For the problem that the data transmission of the resource grain RE level in the related art has interference and causes inaccurate calculation, no effective solution exists at present.

Detailed description of the preferred embodiment 1
This embodiment 1 provides a specific implementation manner for solving the problem of accuracy of interference calculation in the information transmission process. In this embodiment, it is assumed that a target terminal, that is, an interfered terminal, is configured with 2 DMRS ports, and uses a closed-loop transmission method, and an interference source of an adjacent cell uses RE-level precoding polling with a rank of 1.
In the non-transparent open-loop transmission scheme, different space-frequency coding modes or precoding modes are used for DMRS and actual data transmission. During DMRS transmission, a plurality of cells transmit DMRS at the same time-frequency domain position, and a signal received by a target terminal is
Figure BDA0001254482440000181
H denotes the channel matrix on the DMRS port, in the above formula
Figure BDA0001254482440000182
Representing the interfering channel and the interfering signal, and n represents noise. In 5G, multiple adjacent cells may transmit DMRSs at the same time-frequency domain position, orthogonal DMRS sequences may be allocated to the adjacent cells, or an iterative receiver, such as a SIC receiver, may be used to obtain an estimate H of the channel of the cell, and a correlation matrix Rnn of interference and noise components may be estimated by subtracting a signal component
Figure BDA0001254482440000191
In an MMSE-IRC receiver, rnn obtained by using DMRS is used for compressing interference and noise parts when receiving data, so that the performance of a receiving end can be greatly improved.
When the interference source of the adjacent cell adopts RE-level precoding polling transmission with the rank of 1, the Rnn obtained based on the DMRS cannot accurately describe the Rnn during data transmission. Specifically, assuming that the base station of the neighbor cell polls the precoding vector of rank 1 on different RE level resources, generally, the RE level resources may be one RE, one RE group (REG), one subcarrier, one OFDM symbol, and the like. At this time, the correlation matrix of interference and noise can be expressed as
Figure BDA0001254482440000192
Wherein the column vector
Figure BDA0001254482440000193
Denotes the precoding matrix used on the RE level resources and, in general, for 2 DMRS ports,
Figure BDA0001254482440000194
is derived from
Figure BDA0001254482440000195
Since the granularity of the RE level is smaller than that which can be achieved by DMRS,
Figure BDA0001254482440000196
the influence of (2) cannot be reflected on the DMRS and cannot be eliminated during data reception, so Rnn calculation based on the DMRS cannot reflect Rnn during real data transmission, and thus, the performance of data reception is greatly influenced.
The method provided by the embodiment can solve the problem of inaccurate Rnn calculation. The idea of the method is to transmit the precoding with rank 1 in a mode with rank 2, and transmit 2 data symbols on 2 REs to realize the real transmission with rank 1. Fig. 3 is a schematic diagram of an embodiment of precoded polling according to embodiment 1, and as shown in fig. 3, 2 data symbols are transmitted in a precoding manner with rank 2 on one RE, but 2 data symbols are transmitted on a paired RE, and rank 1 transmission is actually performed on the paired RE. Polling the precoded transmission of 2*2 on paired REs, e.g., polling the precoding matrix on RE1 and RE2F 1 And F 2 Transmitting two data symbols s 1 And s 2 ，F 1 And F 2 Is an orthogonal matrix and can be taken from the set of:
Figure BDA0001254482440000197
thus, for the signal on a single RE, since FF can be guaranteed H = I, the effect of the non-transparent precoding matrix F on Rnn calculation can be eliminated. In addition, when the terminal receives data, better data receiving performance can be obtained by averaging the results received on the two REs.
The 2-port example is expanded to a case with more ports, that is, D DMRS ports are configured, S data symbols are transmitted on R REs, D symbols are transmitted on each RE in a precoding polling manner, a used precoding matrix is an orthogonal matrix, and transmission with a rank of S/R is finally achieved. If S data symbols are repeatedly transmitted with different precoding on R REs, then there is D = S. Furthermore, another case is to transmit different subsets of S data symbols on R REs, or different subsets of S data symbols and their conjugate symbols, such that D < S, still a rank S/R transmission is achieved. The base station can inform the terminal of the values of R and S or the value of S/R through high-level signaling or physical layer signaling, so that the terminal can acquire actual transmission rank information to correctly receive the information.
Detailed description of the preferred embodiment 2
The embodiment provides a specific implementation manner for solving the problem of interference calculation accuracy in the information transmission process. In this embodiment, it is assumed that a target terminal, that is, an interfered terminal, is configured with 2 DMRS ports, and uses a closed-loop transmission method, and an interference source of an adjacent cell adopts SFBC or precoding polling proposed in the first embodiment.
In the non-transparent open-loop transmission scheme, different space-frequency coding modes or precoding modes are used for DMRS and actual data transmission. During DMRS transmission, a plurality of cells transmit DMRS at the same time-frequency domain position, and a signal received by a target terminal is
Figure BDA0001254482440000201
H denotes a channel matrix on the DMRS port,
Figure BDA0001254482440000202
representing the interfering channel and the interfering signal, and n represents noise. In 5G, a plurality of adjacent cells transmit DMRSs at the same time-frequency domain position, orthogonal DMRS sequences can be allocated to the adjacent cells, or an iterative receiver such as a SIC receiver is used to obtain an estimate H of a cell channel, and a correlation matrix Rnn of an interference part and a noise part can be estimated by subtracting a signal part
Figure BDA0001254482440000203
In an MMSE-IRC receiver, rnn obtained by using DMRS is used for compressing interference and noise parts when receiving data, so that the performance of a receiving end can be greatly improved. Besides, the Rnn only represents spatial correlation, and when the receiver performs joint reception in the frequency domain or the time domain, the Rnn may obtain a joint correlation matrix of interference and noise in the frequency domain and the frequency domain or the time domain through joint processing in the frequency domain or the time domain, such as averaging processing.
In both SFBC and the precoding polling scheme proposed in the first embodiment, at least 2 REs are required to jointly transmit data, and for an interference source transmitting SFBC, interference received by a target terminal on two REs is
Figure BDA0001254482440000211
For an interference source transmitting pre-coded polling, the interference received by the target terminal on two REs is
Figure BDA0001254482440000212
Therefore, since the same data symbol is transmitted on two REs paired by the interferer, the interference correlation measured by the DMRS on multiple REs cannot completely represent the interference correlation characteristics during channel transmission, which may cause performance impact on a terminal that needs to perform joint reception on multiple resources.
The method can solve the problem of inaccurate interference calculation during time-frequency domain joint data detection. Generally, the base station detects signaling through resource Bundling signaling or resource joint data enabling signaling. And the base station judges the interference condition according to the transmission mode of the adjacent cell and informs the terminal which resource combinations are combined to carry out Bundling or enable combined data detection through signaling. Specifically, the base station selects the resource with the small correlation destruction to perform the joint reception according to the judgment. For example, if a neighboring cell uses two consecutive REs to perform SFBC or precoding polling, a base station of a target cell may configure a terminal to use resource bundling or joint reception with 2-order combing, that is, bundling or joint reception is performed at intervals of 1 resource, fig. 4 is a schematic diagram of a method for indicating resource joint reception in embodiment 2, (bundling mode1 in fig. 4 is a binding mode1, and bundling mode2 in fig. 4 is a binding mode 2), as shown in fig. 4), if the base station determines that the neighboring cell does not perform SFBC or transmission of precoding polling with rank 1, this way may be configured as the left diagram in fig. 4, all resources perform joint reception, if the base station determines that the neighboring cell performs transmission of SFBC or precoding polling with rank 1, this way may be configured as the right diagram in fig. 4, some resources are designated to perform joint reception, and some resources cannot perform joint reception, and the specific indication way may include the following ways:
resource bundling is carried out on L1 resources at intervals, and/or information received by resource combination is enabled;
continuously performing resource bundling on the L2 resources, and/or enabling the resources to jointly receive information;
forbidding resource bundling and/or forbidding resource combination information received by the resources in a combined manner;
and the resource performs B-order combing and bundling and/or enables information received by B-order combing and bundling.
In addition, if the interference changes dynamically, the base station cannot judge which interference on the RE has a correlation characteristic different from that of the DMRS, and the base station may configure resource bundling to perform hopping on different time-frequency domain resources through a high-level signaling or a physical layer signaling, and configure a correlation hopping manner, so that a certain randomization characteristic may be achieved, which is helpful for performance influence caused by inaccurate interference correlation calculation to a certain extent.
Detailed description of preferred embodiments 3
The embodiment provides a specific implementation manner for solving the problem of interference calculation accuracy in the information transmission process. In this embodiment, it is assumed that a target terminal, that is, an interfered terminal, is configured with 2 DMRS ports, and uses SFBC or the precoding polling in the first embodiment, and an interference source of an adjacent cell uses SFBC or the precoding polling proposed in the first embodiment.
In the non-transparent open-loop transmission scheme, different space-frequency coding modes or precoding modes are used for DMRS and actual data transmission. During DMRS transmission, a plurality of cells transmit DMRS at the same time-frequency domain position, and a signal received by a target terminal is

H denotes a channel matrix on a DMRS port,
Figure BDA0001254482440000222
representing the interfering channel and the interfering signal, and n represents noise. In 5G, multiple adjacent cells may transmit DMRSs at the same time-frequency domain position, orthogonal DMRS sequences may be allocated to the adjacent cells, or an iterative receiver, such as a SIC receiver, may be used to obtain an estimate H of the channel of the cell, and a correlation matrix Rnn of interference and noise components may be estimated by subtracting a signal component
Figure BDA0001254482440000223
In an MMSE-IRC receiver, rnn obtained by using DMRS is used for compressing interference and noise parts when receiving data, so that the performance of a receiving end can be greatly improved. Besides, the Rnn only represents spatial correlation, and when the receiver performs joint reception in the frequency domain or the time domain, the Rnn may obtain a joint correlation matrix of interference and noise in the frequency domain and the frequency domain or the time domain through joint processing in the frequency domain or the time domain, such as averaging processing.
In both SFBC and the precoding polling scheme proposed in the first embodiment, at least 2 REs are required to jointly transmit data, and for an interference source transmitting SFBC, interference received by a target terminal on two REs is
Figure BDA0001254482440000231
For an interference source transmitting pre-coded polling, the interference received by the target terminal on two REs is
Figure BDA0001254482440000232
Therefore, since the same data symbol is transmitted on two REs of an interferer pair, the interference correlation measured by the DMRS on multiple REs does not completely represent the interference correlation characteristics during channel transmission. At this time, since the target terminal also adopts SFBC or pre-coding polling, multiple paired REs are required to perform joint processing, and at this time, the computation mismatch of interference correlation may cause a large impact on the final data transmission performance.
For the above problem, the solution provided by this embodiment is that the base station signals the terminal to perform resource combination of SFBC or precoding polling. Generally, SFBC uses two consecutive REs for pairing, and if neighboring cells are paired with two consecutive REs, it may cause mismatch in interference Rnn calculation. Therefore, a base station may configure which resources of a terminal may be paired for SFBC or precoding polling, fig. 5 is a schematic view of a resource pairing manner of SFBC or precoding polling in embodiment 3 of the present invention, as shown in fig. 5, the base station may notify users in a cell which resource combination pairs for SFBC or precoding polling, and if it can be ensured that the base stations of neighboring cells do not perform resource combination on the same resource combination, the problem of mismatch in interference calculation may be solved. Specifically, the base station may notify at least one of the following information through higher layer or physical layer signaling:
transmitting information of resource combination at intervals of M1 resources;
transmitting information of resource combination by continuous M2 resources;
transmitting the information of the frequency domain resource with the minimum number and/or the time domain resource with the minimum number in the resource combination;
and transmitting the information of C-order combing by the resource combination.
In addition, because of dynamic interference change, the base station can hop resources of transmission resource combination on different time-frequency domain resources and configure a terminal hopping mode, so that an interference randomization effect can be achieved, and the performance is beneficial.
