Description

TECHNICAL FIELD The present invention relates to the field of communications, and particularly to an information configuration method, an information configuration device, and a communication system.

Multiple-Input Multiple-Output (MIMO) is one of the important physical layer technologies in LTE-Advanced systems and is used to provide spatial diversity gain, spatial multiplexing gain, and array gain. It will be done.

In LTE Release 11 and previous technologies, MIMO technology all adopts a one-dimensional (1D) linear array arranged horizontally and has adaptive capability on the horizontal plane, i.e., it is a two-dimensional (2D) MIMO technology. . 1 and 2 are diagrams showing two types of commonly used planar array structures. FIG. 1 is a structural diagram of a cross polarization two-dimensional planar array, and FIG. 2 is a structural diagram of a uniform linear two-dimensional planar array.

The Release 12 study introduces a 2D planar array that uses Active Antenna System (AAS) technology and provides adaptive control in the horizontal and elevation dimensions to improve system performance. The performance can be improved better, namely 3D MIMO technology.

As shown in Figure 1, M cross-polarized antenna pairs are arranged in each row in the vertical direction, and a total of N cross-polarized antenna pairs are arranged in the horizontal direction. . As shown in Figure 2, in the vertical direction, M antenna arrays with the same polarization direction (for example, the vertically polarized antenna in Figure 2) are arranged in each column, and in the horizontal direction, a total of N columns are arranged. be done. In such two types of configurations, the number of horizontal antenna ports may be the same as the number of antenna ports in previous LTE releases, eg, 1, 2, 4, 8, etc. By virtualizing one physical antenna port using multiple physical antennas in the vertical direction, it is possible to reduce the number of antenna ports that transmit reference signals. Note that when the number of antenna ports in the vertical direction is 1, a 2D planar array degenerates into a conventional 1D array, and 3D MIMO technology also degenerates into 2D MIMO technology accordingly.

It should be noted that the above background art introduction is intended to clearly and completely explain the technical solution of the present invention, and to make it easy for those skilled in the art to understand it. These proposals are described as part of the Background of the Invention and should not be construed as being well known to those skilled in the art.

When the number of antenna ports in the vertical direction is greater than 1, the 3D MIMO technology can be fully utilized to adjust the transmitted signal on the horizontal and vertical planes, but the total number of antenna ports is greater than the number of ports in previous releases. , the number of resources occupied by reference signals, especially channel state information reference signals (CSI-RS), increases. Also, since the antenna becomes two-dimensional from one-dimensional, the reference signal configuration information in the previous release may also cause confusion under the two-dimensional planar array. For example, when configuring only the total number of antenna ports, there are multiple antenna arrangement methods that can satisfy the number of antenna ports, so the receiving side cannot accurately obtain the number of antenna ports in the horizontal and vertical directions.

For example, according to the current release of protocol TS 36.331, V11.5.0 requires horizontal and There is no need for vertical division. That is,
antennaPortsCount-r10 ENUMERATED{an1,an2,an4,an8},
resourceConfig-r10 INTEGER(0..31),
subframeConfig-r10 INTEGER(0..154),
pC-r10 INTEGER(-8..15)
It is.

However, the current antenna arrangement scheme can be determined when the antennas of the previous release were all one-dimensional and the configuration information dictated the number of antenna ports. When using a two-dimensional antenna array, it is not possible to determine the antenna arrangement method by only informing the number of antenna ports. FIG. 3 is a diagram showing a possible antenna arrangement in the case of 8 antenna ports, and FIG. 4 is a diagram showing a possible antenna arrangement in the case of 4 antenna ports. As shown in Figures 3 and 4, 8 antennas and 4 antennas represent 7 and 5 possible antenna configurations, respectively, so configuring the number of transmit antenna ports only according to the current release protocol is insufficient. It is.

It should be noted that the invention is not limited to the described modes of implementation, but includes all modifications, variations and alternatives that fall within the scope of the appended claims. Hereinafter, various implementation methods of the present invention will be explained based on the drawings. Note that these implementation methods are merely examples and are not intended to limit the present invention.

Embodiment 1 of the present invention provides an information configuration method. FIG. 5 is a flowchart of the method, and as shown in FIG. 5, the method includes the following steps.

Step 501: The base station performs virtualization on the two-dimensional planar antenna array (also referred to as after virtualization of the two-dimensional planar antenna array), and based on the antenna port that is formed (i.e., the two-dimensional planar antenna mapping relationship between the configuration information of one or more sets of reference signals and the instruction information for indicating the configuration information for the user equipment (based on the antenna ports formed by virtualizing the array) constitute;
The configuration information includes antenna polarization indication information, horizontal or vertical antenna port indication information; number of horizontal antenna ports and number of vertical antenna ports; total number of antenna ports of the system and horizontal antenna ports. total number of antenna ports in the system and number of antenna ports in the vertical direction; information indicating the antenna arrangement method; information indicating whether to weight reference signals; number of configured reference signal sets; user-specific vertical reference Number of signal ports; number of columns in which antenna ports are located in the vertical direction; number of antenna ports in each column in the vertical direction or total number of antenna ports occupied in the vertical direction; number of reference signal ports in the horizontal direction dedicated to the user; horizontal direction and the number of antenna ports in each row in the horizontal direction or the total number of antenna ports occupied in the horizontal direction.

In this embodiment, the base station configures the configuration information for the user equipment based on the antenna ports that are formed after virtualizing the two-dimensional planar antenna array. It can be made suitable for a two-dimensional planar antenna array, and thereby the user side can accurately obtain array configuration information.

In this embodiment, configuration information can be indicated using an n-bit indication state, where n is a positive integer. For example, 1-bit instruction states "0" and "1" may be adopted to indicate two sets of configuration information; 2-bit instruction states "00, 01, 10, 11" may be adopted to indicate 4 sets of configuration information. You may also specify the configuration information. Note that the specific number of bits used to indicate the configuration information may be determined depending on the actual situation.

In this embodiment, the above-mentioned mapping relationship is configured on the base station side, and the mapping relationship is stored on the user side and the base station side, so that the user equipment can respond to the instruction information after receiving the instruction information. Corresponding processing can be performed based on the configuration information. Hereinafter, an example of how to configure the above-mentioned configuration information and the above-mentioned mapping relationship on the base station side will be described.

In one implementation of this embodiment, when configuring horizontal or vertical antenna ports separately, the configuration information includes horizontal or vertical antenna port designation, antenna polarization designation, and/or antenna polarization designation. Contains arrangement method instructions.

In this case, the user side can determine the transmitting side array configuration based on the above configuration information, so there is no need to separately configure the total number of antenna ports of the system. Therefore, the user side can recover the entire channel information (the channel configured by all antennas on the transmitting side and the antennas on the user side), which reduces the occupied resource elements and improves the data transmission service. This makes it possible to avoid a reduction in the number of resource elements and improve system throughput.

The configuration information may further include horizontal and/or vertical resources, subframes, and/or power information.

In this embodiment, when configuring horizontal or vertical antenna ports independently, the configuration information may include the following specific information:
(1-a) Horizontal or vertical antenna port designation enumeration {horizontal, vertical},
(1-b) Polarization instruction Enumeration {0/90 cross polarization, 45/-45 cross polarization, vertical polarization, horizontal polarization,...},
(1-c) Number of antenna ports enumeration {an1, an2, an4, an8},
(1-d)resourceConfig-r10 INTEGER(0..31),
(1-e)subframeConfig-r10 INTEGER(0..154),
(1-f)pC-r10 INTEGER(-8..15)
It is.

In this embodiment, the configuration may be performed only in the horizontal direction, the configuration may be performed only in the vertical direction, or the configuration may be performed in the horizontal direction and the vertical direction.

In this embodiment, the configuration information including the above-mentioned information is one set or multiple sets, and each set may be indicated by n-bit instruction information. Note that the specific number of bits to be adopted may be determined depending on the actual situation.

For example, when configuring in the horizontal direction and configuring four sets of configuration information, 2-bit instruction information may be used to provide instructions as shown in Table 1. Note that since the configuration in the vertical direction is similar to Table 1, detailed explanation thereof will be omitted here.

Table 1 shows the mapping relationship between configuration information and instruction information.

In another implementation of this embodiment, when jointly configuring horizontal or vertical antenna ports, the configuration information may include antenna polarization instructions and/or Contains numbers. The configuration information may further include horizontal and vertical resources, subframes, and/or power information.

In this embodiment, the horizontal and vertical resource information and/or subframe information may be configured as one set or more than one set. For example, among the following configuration information examples, (3-c) (4-c) is an example in which the resource information is configured as one set, and (4-c) is an example in which the resource information is configured as one or more sets.

For example, when performing joint configuration for horizontal or vertical antenna ports, the configuration information includes the following specific information:
(2-a) Polarization instruction Enumeration {cross polarization, vertical polarization, horizontal polarization,...},
(2-b) Number of horizontal antenna ports Enumeration {an1, an2, an4, an8,…},
(2-c) Number of vertical antenna ports Enumeration {an1, an2, an4, an8,…},
(2-d)Horizontal resourceConfig-r10 INTEGER(0..31),
(2-e) Vertical resourceConfig-r10 INTEGER(0..31),
(2-f)Horizontal subframeConfig-r10 INTEGER(0..154),
(2-g) Vertical subframeConfig-r10 INTEGER(0..154),
(2-h) Horizontal direction pC-r10 INTEGER(-8..15),
(2-i) Vertical pC-r10 INTEGER(-8..15)
It is.

In this embodiment, if the vertical and horizontal parameters are always the same, it may be configured only once; for example, (2-f) and (2-g) may be combined and configured (2 -h) and (2-i) are combined.

In other implementations of this embodiment, when jointly configuring horizontal or vertical antenna ports, the configuration information includes the antenna polarization indication and/or the total number of antenna ports in the system; Includes the number of horizontal or vertical antenna ports.

For example, the above configuration information (2-b) and (2-c) may be changed as follows, that is,
(2-b1) Total number of antenna ports in the system Enumeration {an1, an2, an4, an8,…},
(2-c1) Number of horizontal antenna ports Enumeration {an1, an2, an4, an8, …}, or
(2-b2) Total number of antenna ports in the system Enumeration {an1, an2, an4, an8, …},
(2-c2) Number of vertical antenna ports enumeration {an1, an2, an4, an8,…}
It is.

Similarly, the configuration information including the above information may be one set or multiple sets, and each set may be indicated by n-bit instruction information. Note that the specific number of bits to be adopted may be determined depending on the actual situation. Since this was similar to Table 1 above, detailed explanation thereof will be omitted here.

In another implementation method of this embodiment, when configuring antenna ports that do not distinguish between horizontal and vertical directions, the configuration information includes the number of antenna ports and antenna arrangement method instruction information.

For example, when configuring an antenna port that does not distinguish between horizontal and vertical directions, the configuration information includes the following specific information:
(3-a) Number of antenna ports Enumeration { an1, an2, an4, an6, an8, an9, an10, an12, an15, an16, …},
(3-b) Antenna arrangement method instruction Enumeration {a, b, c, d, e, f, g, h, i, …},
(3-c)resourceConfig-r10 INTEGER(0..31),
(3-d)subframeConfig-r10 INTEGER(0..154),
(3-e)pC-r10 INTEGER(-8..15)
It is.

Among them, a, b, c, d, e, f, g, h, i, etc. in (3-b) are the numbers of possible antenna arrangement methods.

Similarly, the configuration information including the above information may be one set or multiple sets, and each set may be indicated by n-bit instruction information. Note that the specific number of bits to be adopted may be determined depending on the actual situation. This is similar to Table 1 above, so detailed explanation thereof will be omitted here.

In this embodiment, when estimation and feedback are performed independently in the horizontal and vertical directions, since the change characteristics of each channel are different, there is a possibility that the two constituent periods and/or feedback periods will be different. be. Therefore, by utilizing such characteristics, relatively accurate channel estimation results can be obtained. Hereinafter, an example in which the configuration/feedback period in the vertical direction is longer than that in the horizontal direction will be explained.

であり、xは、W_Vの列数及びW_Hの行数を示し、例えば、x＝NN_V(N_V＜M)であり、N_Vは、垂直方向にサポートするデータ流の数である。この場合、3Dチャネルと垂直及び水平方向のプリコーディング行列の乗積は、次のようなブロック行列とすることができる。

The format of the signal received at the user side is Y=HW _V W _H s+n, where H is the actual transmission channel, W _V and W _H are the vertical and horizontal precoding matrices, respectively. , and s and n are the transmitted signal and the noise added at the user side, respectively. The dimensions of the channel and precoding matrix are
(Outside 1)

, where x indicates the number of columns of W _V and the number of rows of W _H , e.g., x=NN _V (N _V <M), and N _V is the number of data streams supported in the vertical direction. . In this case, the product of the 3D channel and the vertical and horizontal precoding matrices can be a block matrix as follows.

Among them, H _n =(n=1,2,…,N) is the channel message between the nth column physical antenna on the transmitting side and all antennas on the user side, and W ⁿ _V (M× N _r ) is a precoding matrix of the vertical channel in the n-th column, and N and M are the numbers of antennas in the horizontal and vertical directions, and are positive integers. Therefore, using one column, some columns, or all columns of H, the vertical precoding matrix W ⁿ _V (M×N _r ) or multiple W ⁿ _V (M×N _r ) or W _V It is better to obtain more channel information in order to be able to estimate the entire matrix and also to perform vertical PMI estimation.

In this embodiment, the value of x may be taken by adopting another method, and the present embodiment is not limited to this.

Since the positions of the user ends are different, the differences between the channels in each column in the vertical direction are also different. When the difference between the channels of each column is relatively small, the estimated PMI value for each column is the same. In order to make the most efficient use of the reference signal resources, different configurations on the user side are used, as well as different numbers of vertical channels (antenna ports placed vertically in each column and antenna ports on the user side). The channel configured by all the antennas may be one vertical channel). At the same time, the number of the column where the vertical antenna is located may be transmitted so that the user side can better recover the entire 3D channel information.

Therefore, in this embodiment, the configuration information may be further configured to include one or more of the following information: information indicating whether to weight the reference signal; number of reference signal sets in the vertical direction; number of vertical reference signal ports dedicated to the user; number of the column in which the antenna port is located in the vertical direction; number of antenna ports in each vertical column or total number of antenna ports occupied in the vertical direction ; the number of horizontal reference signal ports dedicated to the user; the number of the row in which the antenna port is located in the horizontal direction; and the number of antenna ports in each row in the horizontal direction or the total number of antenna ports occupied in the horizontal direction.

In one implementation method of the present embodiment, the configuration information includes the number of configured reference signal sets; for example, when configuring multiple reference signal resources for vertical antennas, the configuration information includes the following: may also include, i.e.,
(4-a) Number of antenna ports in each column in the vertical direction Enumeration {an1, an2, an3, an4, …},
(4-b) Enumeration of column numbers where antenna ports are located in the vertical direction {c1, c2, c3, …},
(4-c)resourceConfig-r10 INTEGER(0..31), INTEGER(0..31), INTEGER(0..31),…
(4-d)subframeConfig-r10 INTEGER(0..154),
(4-e)pC-r10 INTEGER(-8..15)
It is.

Among them, c1, c2, c3, etc. are different combinations of multiple column numbers. For example, if there are 4 column antennas in the system, there are ²⁴ possible column combinations, that is, 4 bits. can be used to represent all 16 possible combinations. In addition, the occupancy status of vertical antenna columns may be indicated by a bit mapping method, that is, there are 4 columns of antennas, and each column of antennas is indicated by 1 bit, and the value of the corresponding bit is 1. The presence indicates that reference signal resources are configured for the vertical column, and the value of the corresponding bit is 0 indicates that reference signal resources are not configured for the column.

Similarly, the configuration information including the above information may be one or more sets, each of which may be indicated by n bits of instruction information. Note that the specific number of bits to be adopted can be determined depending on the actual situation. This is similar to Table 1 above, so detailed explanation thereof will be omitted here.

In this embodiment, by configuring multiple sets of configuration information, that is, by indicating the use of multiple reference signal resources, the receiving side can estimate more channel information in order to perform better CSI measurement. can do.

In one implementation method of the present embodiment, the configuration information includes the number of configured reference signal sets, and for example, when configuring one reference signal resource for all antennas occupied in the vertical direction, the configuration information includes the number of configured reference signal sets. Configuration information may include:
Total number of antenna ports occupied in the vertical direction Enumeration {an1, an2, an3, an4, …},
Number of the column where the antenna port is located in the vertical direction Enumeration {c1, c2, c3, …},
resourceConfig-r10 INTEGER(0..31),
subframeConfig-r10 INTEGER(0..154),
pC-r10 INTEGER(-8..15)
It is.

In this case, antenna ports that transmit reference signals in multiple columns in the vertical direction occupy one reference signal configuration having a large number of ports.

In this embodiment, after the user end obtains W _V or some columns of the precoding matrix W ⁿ _V (M×N _r ), since the vertical PMI update cycle is relatively long, HW _V or HW Horizontal PMI can be estimated using some columns of _V. Similar to the vertical direction, the horizontal reference signal can also occupy a relatively large amount of resources to estimate all the columns of HW _V , or it can save some resources and estimate only a part of HW _V. can also be estimated, and the construction method is the same as the vertical construction method, so detailed explanation thereof will be omitted here.

However, it is necessary to weight the horizontal reference signal using all or some sub-matrix blocks of _WV , and in this embodiment, in order to distinguish it from the vertical reference signal, The configuration information may further include instruction information on whether to weight the reference signal, for example,
Weighting Instructions Enumeration {Yes, No}
It is.

In this embodiment, when the configuration/feedback period in the horizontal direction is longer than that in the vertical direction, the reference signal in the vertical direction may also include instruction information on whether to weight the reference signal, and the implementation method is as follows: Since this is similar to the implementation method when the configuration/feedback cycle is longer than the horizontal direction, detailed explanation thereof will be omitted here.

In this embodiment, the above-mentioned reference signal may be a CSI-RS, or may be an antenna reference signal with a channel estimation function in a communication system, but the present embodiment is not limited to this.

In this embodiment, the configuration method described above may be used alone or in combination with the information included in the configuration message. For example, when the number of antenna ports in the system is relatively large (at least greater than 8), e.g., a uniform linear two-dimensional planar array as shown in Figure 2, any row or rows of antennas can be connected to vertical antenna ports. , any one or more rows of antennas may be defined as a horizontal antenna port, and configuration may be performed independently for horizontal and vertical antenna ports. Alternatively, joints may be used for horizontal and vertical ports. Also, for example, when the number of antenna ports in the system is not large, for example, 8 or less or 16 or less, in addition to using the configuration method described above, it is also possible to use a configuration method that does not distinguish between horizontal and vertical directions. You may do so. Note that what is described here is merely an example, and the embodiments of the present invention are not limited thereto.

As can be seen from the above embodiment, the base station configures the configuration information for the user equipment based on the antenna ports formed after the two-dimensional planar antenna array virtualization, so that the configuration information becomes two-dimensional. It can be made suitable for a planar antenna array, and thereby the user can accurately obtain array configuration information.
