Description

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

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

In LTE Release 11 and earlier technologies, all MIMO technologies adopt horizontally arranged one-dimensional (1D) linear arrays and have adaptive capabilities in the horizontal plane, i.e., two-dimensional (2D) MIMO technologies. . 1 and 2 are diagrams showing the structures of two commonly used planar arrays. FIG. 1 is a structural diagram of a cross polarized two-dimensional planar array, and FIG. 2 is a structural diagram of a uniform linear two-dimensional planar array.

A 2D planar array was introduced in the Release 12 study, using techniques related to Active Antenna Systems (AAS) and providing adaptive control in the horizontal and elevation dimensions to improve system performance. It can improve the performance better, namely 3D MIMO technology.

As shown in Figure 1, M cross-polarized antenna pairs are arranged in each column in the vertical direction, and a total of N cross-polarized antenna pairs are arranged in the horizontal direction. . As shown in Figure 2, M antenna arrays with the same polarization direction are arranged in each row in the vertical direction (for example, vertically polarized antennas in Figure 2), and a total of N rows are arranged in the horizontal direction. be done. In these two configurations, the number of antenna ports in the horizontal direction may be the same as in previous LTE releases, eg 1, 2, 4, 8, and so on. Multiple physical antennas in the vertical direction can reduce the number of antenna ports transmitting reference signals by virtualizing one physical antenna port. It should be noted that when the number of antenna ports in the vertical direction is 1, the 2D planar array degenerates into a conventional 1D array, and the 3D MIMO technology degenerates into a 2D MIMO technology accordingly.

It should be noted that the above introduction of the background art is for the purpose of clearly and completely describing the technical solution of the present invention and making it easier for those skilled in the art to understand it. These proposals are described in part in the Background of the Invention and should not be construed as being known to those skilled in the art.

3D MIMO technology can be fully utilized to adjust the transmitted signal on the horizontal and vertical planes when the number of antenna ports in the vertical direction is greater than 1, but the total number of antenna ports is the number of ports in the previous release. , increasing the number of resources occupied by reference signals, especially Channel State Information Reference Signals (CSI-RS). Also, as antennas go from one-dimensional to two-dimensional, the reference signal configuration information in previous releases can also cause confusion under two-dimensional planar arrays. For example, when configuring only the total number of antenna ports, there are a plurality of 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 protocol TS 36.331, V11.5.0 can be used for horizontal and There is no need to partition vertically. Namely
antennaPortsCount-r10 ENUMERATED {an1,an2,an4,an8},
resourceConfig-r10 INTEGER(0..31),
subframeConfig-r10 INTEGER(0..154),
pC-r10 INTEGER(-8..15)
is.

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

Various embodiments of the present invention will be described below with reference to the drawings. It should be noted that these implementations 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 post-virtualization of the two-dimensional planar antenna array), based on the antenna ports formed (that is, the two-dimensional planar antenna mapping relationship between configuration information of one or more sets of reference signals and indication information for indicating the configuration information for the user equipment (based on antenna ports formed by virtualizing the array) constitute;
The configuration information includes antenna polarization indication information, horizontal or vertical antenna port indication information; horizontal antenna port number and vertical antenna port number; system total antenna port number and horizontal antenna port number. the total number of antenna ports in the system and the number of vertical antenna ports; the antenna arrangement method indication information; the indication information whether to weight the reference signals; the number of configured reference signal sets; 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 ports of horizontal reference signals dedicated to users; 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 formed after performing virtualization on the two-dimensional planar antenna array, so that the configuration information is It can be made suitable for a two-dimensional planar antenna array, so that the user side can obtain the array configuration information accurately.

In this embodiment, an n-bit indication state can be used to indicate configuration information, where n is a positive integer. For example, 1-bit indication states "0" and "1" may be used to indicate 2 sets of configuration information; 2-bit indication states "00, 01, 10, 11" may be used to indicate 4 sets. configuration information may be indicated. It should be noted that the specific number of bits used to indicate the configuration information may be determined according to the actual situation.

In this embodiment, by configuring the above-mentioned mapping relationship on the base station side and storing the mapping relationship on the user side and the base station side, the user equipment can correspond to the indication information after receiving the indication information. Corresponding processing can be performed based on the configuration information provided. Hereinafter, it will be exemplified how the base station side configures the above configuration information and the above mapping relationship.

In one implementation of the present embodiment, when configuring separately for horizontal or vertical antenna ports, the configuration information includes horizontal or vertical antenna port indication, antenna polarization indication and/or antenna Contains alignment instructions.

In this case, the user side can determine the array configuration of the transmitting side based on the above-described 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 information of the entire channel (the channel formed by all the antennas of the transmitting side and the antennas of the user side), thereby reducing the occupied resource elements and improving the data transmission service. It is possible to avoid the reduction of the number of resource elements for the system and improve the throughput of the system.

Among them, the configuration information may further include horizontal and/or vertical resource and/or subframe and/or power information.

In this embodiment, when configuring independently for horizontal or vertical antenna ports, the configuration information may include the following specific information:
(1-a) Horizontal or Vertical Antenna Port Designation Enumeration {horizontal, vertical},
(1-b) Polarization indication 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)
is.

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

In this embodiment, the configuration information including the above information may be one set or multiple sets, each of which may be indicated by n-bit indication information. Note that the number of bits to be specifically employed may be determined according to the actual situation.

For example, when configuring in the horizontal direction and configuring 4 sets of configuration information, as shown in Table 1, 2-bit indication information may be used to indicate. In addition, the configuration in the vertical direction is similar to Table 1, so detailed description thereof is omitted here.

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

In another implementation of this embodiment, when configuring a joint for horizontal or vertical antenna ports, the configuration information includes antenna polarization instructions and/or horizontal and vertical antenna ports. Including numbers. Among them, the configuration information may further include horizontal and vertical resource and/or subframe 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. 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 configuring joints for horizontal or vertical antenna ports, the configuration information includes the following specific information:
(2-a) Polarization indication enumeration {cross polarization, vertical polarization, horizontal polarization, …},
(2-b) Enumeration of number of horizontal antenna ports {an1, an2, an4, an8, …},
(2-c) Enumeration of number of vertical antenna ports {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 pC-r10 INTEGER(-8..15),
(2-i) Vertical pC-r10 INTEGER(-8..15)
is.

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

In another implementation of this embodiment, when configuring joints for horizontal or vertical antenna ports, the configuration information includes antenna polarization indication and/or the total number of antenna ports in the system, and Includes the number of antenna ports in the horizontal or vertical direction.

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

Similarly, the configuration information including the above information may be one set or multiple sets, each of which may be indicated by n-bit indication information. Note that the number of bits to be specifically employed may be determined according to the actual situation. Since this is similar to Table 1 above, its detailed description is omitted here.

In another implementation method of this embodiment, when configuring antenna ports that are not divided into horizontal and vertical directions, the configuration information includes the number of antenna ports and antenna arrangement indication 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 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)
is.

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

Similarly, the configuration information including the above information may be one set or multiple sets, each of which may be indicated by n-bit indication information. Note that the number of bits to be specifically employed may be determined according to the actual situation. This is similar to Table 1 above, so its detailed description is omitted here.

In this embodiment, when estimation and feedback are performed independently in the horizontal direction and the vertical direction, the change characteristics of each channel are different, so the configuration period and/or feedback period of the two may be different. be. Therefore, such characteristics can be used to obtain relatively accurate channel estimation results. An example in which the configuration/feedback period in the vertical direction is longer than in the horizontal direction will be described below.

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

and x denotes the number of columns of W _V and the number of rows of W _H , for example x=NN _V (N _V <M), where N _V is the number of data streams to support vertically. . 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 _r ) is the n-th column of the vertical channel precoding matrix, N and M are the number of horizontal and vertical antennas 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 In order to be able to estimate the entire matrix and also to estimate the vertical PMI, it is better to have more channel information.

In this embodiment, x may adopt other methods to take its value, and this embodiment is not limited to this.

Since the user edges are located at different locations, the differences between the channels in each vertical column are also different. The estimated PMI values for each column are the same when the difference between channels in each column is relatively small. In order to make the most efficient use of the reference signal resource, different configurations for the user side can also be achieved with different number of vertical channels (vertically arranged antenna ports per column and user side The channel formed by all antennas is one vertical channel). At the same time, the column number of the vertical antenna can be transmitted so that the user side can recover the entire 3D channel information better.

Thus, in this embodiment, the configuration information may be further configured to include one or more of the following information: an indication of whether to weight reference signals; the number of vertical reference signal ports dedicated to the user; the column number where the antenna ports are located in the vertical direction; the number of antenna ports in each column in the vertical direction or the total number of antenna ports occupied in the vertical direction. the number of horizontal reference signal ports dedicated to users; the number of rows in which antenna ports are 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 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 is: may include those of, i.e.
(4-a) Enumeration {an1, an2, an3, an4, …}, the number of antenna ports in each row in the vertical direction,
(4-b) Enumeration {c1, c2, c3, …} of columns in which antenna ports are located in the vertical direction,
(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)
is.

Among them, c1, c2, c3, etc. are different combinations of multiple column numbers. For example, if there are 4 columns of 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 bit mapping, i.e., four columns of antennas, each column of antennas is indicated by 1 bit, and the corresponding bit value is 1. A presence indicates that a reference signal resource is configured for the vertical column, and a value of 0 for the corresponding bit indicates that no reference signal resource is configured for the column.

Similarly, there may be one set or multiple sets of configuration information including the above information, each indicated in the n-bit indication information. In addition, the number of bits to be specifically adopted can be determined according to the actual situation. This is similar to Table 1 above, so its detailed description is omitted here.

In this embodiment, by configuring multiple sets of configuration information, i.e., by indicating the use of multiple reference signal resources, the receiver can estimate more channel information for better CSI measurement. can do.

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

In this case, antenna ports transmitting 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 column precoding matrix W ⁿ _V (M×N _r ), the vertical PMI update period is relatively long, so that HW _V or HW Some columns of _V can be used to estimate horizontal PMI. Similar to the vertical direction, the horizontal reference signal can also occupy a relatively large amount of resources to estimate the entire column of HW _V , and also save some resources to estimate only a part of HW _V. can also be estimated, and the construction method is the same as the vertical construction method, so its detailed description is omitted here.

However, at the time of the horizontal reference signal at this time, it is necessary to perform weighting using all or part of W _V sub-matrix blocks. The configuration information may further include an indication of whether to weight the reference signals, for example:
Weighting Instruction Enumeration {yes, no}
is.

In this embodiment, if the configuration/feedback period in the horizontal direction is longer than in the vertical direction, the reference signal in the vertical direction may also contain an indication of whether to weight the reference signal, and the implementation is as follows: Since this method is similar to the implementation method when the configuration/feedback period is longer than the horizontal direction, the detailed description thereof is omitted here.

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

In this embodiment, the configuration methods described above may be used alone or in combination with the information contained 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 Fig. 2, any single or multiple rows of antennas can be connected to vertical antenna ports. , any one or more rows of antennas may be defined as horizontal antenna ports, and configurations may be made independently for horizontal and vertical antenna ports. Alternatively, joints may be configured for horizontal and vertical ports. Also, for example, when the number of antenna ports in the system is not large, for example, when the number of antenna ports is 8 or less or 16 or less, in addition to performing configuration using the above configuration method, a configuration method that does not distinguish between horizontal and vertical directions is used. You can It should be noted that the description here is merely an example, and the embodiments of the present invention are not limited to this.

As can be seen from the above embodiments, the base station configures the configuration information for the user equipment based on the antenna ports formed after virtualization of the two-dimensional planar antenna array, so that the configuration information is two-dimensional It can be made suitable for planar antenna arrays, so that the user side can obtain the array configuration information accurately.
