Description

Downlink signal sending method of horizontal antenna array and base station

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a downlink signal sending method of a horizontal antenna array and a base station.

Background

At present, a large-scale multiple-input multiple-output (massive MIMO) antenna with 16 horizontal channels is mainly formed by horizontally placing 8 columns of dual-polarized elements, each dual-polarized element comprises 2 antenna units with different polarization directions, the 8 columns of dual-polarized elements comprise 16 antenna units in total, and each antenna unit corresponds to one channel. How to map the logical ports to the antenna elements when the antennas transmit downlink signals, such as channel state information reference signals (CSI-RS), demodulation reference signals (DMRS) and Synchronization Signal Blocks (SSB), has been a focus of research.

In practical applications, it is usually desirable to implement lossless mapping, i.e. the amplitudes of the 16 antenna elements are all 1, and the weights of the mapping are changed by changing the phase only, while the lossless weights required for different beamwidths are different. Currently, a scheme for forming a horizontal wide beam is to use lossy weights, i.e., the amplitudes are not all 1. In the scheme, due to the lossy mapping, the actual total transmission power of 16 antenna units does not reach the set total power, and the problem of power loss exists.

Fig. 1 shows a mapping manner using the same-polarization lossless weights, as shown in fig. 1, 8 same-polarization antenna units are mapped to a first logical port, and the other 8 same-polarization antenna units are mapped to a second logical port. Referring to fig. 2, it can be seen that although the beam width reaches more than 70 degrees, which meets the requirement of about 65 degrees, the antenna shown in fig. 1 has the following two disadvantages: firstly, the maximum value of the antenna gain deviates from the normal direction by about 12 degrees, and secondly, a larger side lobe is introduced at the edge of a cell, so that interference can be caused to the adjacent cell.

Referring first to fig. 3, fig. 3 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 31 and a network device 32. The terminal 31 may also be referred to as a User terminal or a User Equipment (UE), where the terminal 31 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 31 is not limited in the embodiment of the present invention.

The base stations may communicate with the terminals 31 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base stations may communicate wirelessly with the terminals 31 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area.

The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments.

The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

Referring to fig. 4, an embodiment of the present invention provides a method for sending a downlink signal of a horizontal antenna array, which may form a horizontal wide beam by using a lossless mapping method, and in addition, the embodiment of the present invention may also effectively reduce a side lobe amplitude and enable a maximum gain of an antenna to be located near a normal direction. As shown in fig. 4, in the downlink signal transmitting method of a horizontal antenna array provided in the embodiment of the present invention, the horizontal antenna array includes multiple rows of dual-polarized arrays, each dual-polarized array includes two antenna units with different polarization directions, and the method includes:

and 41, establishing a mapping relation between the logic ports and the multi-column dual-polarized array, wherein in the mapping relation, the amplitude weight value of each logic port mapped to each antenna unit is 1.

In order to implement lossless mapping, in the mapping relationship in the embodiment of the present invention, the amplitude weight of the logical port mapped to each antenna unit is 1, and the phases of each antenna unit may be the same or different. Preferably, in the mapping relationship in the embodiment of the present invention, there may be antenna units with the same logical port mapped to different polarization directions, that is, one logical port may be mapped to antennas with different polarization directions of the same antenna unit, or antennas with different polarization directions mapped to different antenna units.

And step 42, mapping the signals of the logic ports to the multi-column dual-polarized array for transmission according to the mapping relation.

Here, when sending a downlink signal, the embodiment of the present invention maps the signal of the logical port to each dual-polarized array for sending according to the amplitude weight and the relative phase relationship in the mapping relationship, thereby implementing lossless mapping of the signal.

The above-described method of embodiments of the present invention will be further described below by way of a number of examples.

Example 1: 16 lanes mapping to 1 logical port

Here, the number of the logical ports is 1, and in the mapping relationship, the logical ports are mapped to each antenna element of the 8 columns of dual-polarized arrays. The mapping relationship has antenna units with the same logical port mapped to different polarization directions.

1.1 the beam width in the beam pattern is around 30 degrees:

scheme 1.1.1: mapping 16 antenna elements to 1 logical port in the manner of fig. 5, the virtual 16 antenna elements have phase weights from left to right of 000001800180000001800180, here in degrees (°), which are the same in the following examples, as shown in table 1. Table 1 and the following tables are each made by taking the center value of the relative phase as an example. In the embodiment of the present invention, the relative phase of a certain antenna unit may also be a value within a range of ± 30 degrees based on the central value. For example, the phase of the antenna element numbered 1 in table 1 may be 0, or may be arbitrarily set within-30 degrees to +30 degrees. The following tables are similar and will not be repeated for economy.

Antenna unit	1	2	3	4	5	6	7	8
									Phase position	0	0	0	0	0	0	0	0
Antenna unit	9	10	11	12	13	14	15	16
									Phase position	0	0	180	180	0	0	180	180

TABLE 1

That is to say, the multiple columns of dual-polarized arrays in fig. 5 include 8 columns of dual-polarized arrays, the number of the logic ports is 1, and in the mapping relationship, the logic ports are mapped to each antenna unit of the 8 columns of dual-polarized arrays. It can be seen that there are antenna units in the mapping relationship, where the same logical port is mapped to different polarization directions. When the 16 antenna elements of the 8 columns of dual-polarized arrays are numbered sequentially in a first polarization direction (e.g., a direction corresponding to-45 degrees) and then numbered sequentially in a second polarization direction (e.g., a direction corresponding to +45 degrees), the relative phase between each antenna element in the mapping relationship is within ± 30 degrees on the basis of the corresponding central value, where: the center values of the relative phases of the logical ports mapped to the antenna elements numbered 1, 9, 2, 10, 3, 11, 4, 12, 5, 13, 6, 14, 7, 15, 8, and 16 are 0, 180, 0, 180, 0, and 180 degrees, respectively.

It should be noted that the phase relationship herein means the relative phase between the antenna elements. For example, when the antenna element numbered 1 is used as a reference phase (i.e., the phase value is 0), the phase values of the other antennas relative to the antenna element numbered 1 are set. For example, when the antenna element phase value of number 16 is 180 degrees, that is, the antenna element phase value of number 16 is obtained by adding 180 degrees to the phase value of the antenna element of number 1. Each of the following examples is similar.

Fig. 6 shows the resultant pattern of the antenna array of the mapping shown in fig. 5, and it can be seen that the beam width is about 30 degrees.

Example 2: 16 lanes mapping to 2 logical ports

Here, the multiple columns of dual-polarized arrays include 8 columns of dual-polarized arrays, and when the number of the logic ports is 2, the first logic port (for example, logic port 0) is mapped to two antenna elements of the first dual-polarized array, the second dual-polarized array, the third dual-polarized array, and the fourth dual-polarized array; the second logical port (for example, logical port 1) is mapped to two antenna elements of the fifth dual-polarized array, the sixth dual-polarized array, the seventh dual-polarized array, and the eighth dual-polarized array. The mapping relationship has antenna units with the same logical port mapped to different polarization directions.
