Description

Method and device for beam forming

Technical field

This application relates to the field of communication technology, and in particular to a beamforming method and device.

Background technique

An important performance improvement of the fifth-generation (the 5th gerneration, 5G) communication compared to the fourth-generation (the 4th gerneration, 4G) communication is that broadcast channels, control channels, or dedicated channels can be beamforming. Through beamforming, broadcast channels, control channels, or dedicated channels can achieve high equivalent isotropically radiated power (EIRP) and concentrated energy to improve coverage and reduce interference.

The beamforming weights need to be used in beamforming. In the existing method, the weights used for beamforming are directly stored in the antenna device.

The main problem with the above method is that the accuracy of the weights used for beamforming stored in the antenna device is insufficient, which results in low accuracy of beamforming.

Detailed ways

In order to make the purpose, technical solutions, and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. The specific operation method in the method embodiment can also be applied to the device embodiment or the system embodiment. Wherein, in the description of the present application, unless otherwise specified, "multiple" means two or more.

As shown in Figure 1, it is a schematic diagram of a network architecture to which this application applies. The network architecture includes a baseband processing unit (Building Baseband Unit, BBU), a radio remote unit (RRU), an antenna device, and a feeder. Among them, the feeder line is used to connect the antenna device and the RRU, and the antenna device and the feeder line may also be collectively referred to as an antenna feeder or an antenna feeder system. The BBU mainly completes functions such as channel encoding and decoding, baseband signal modulation and demodulation, and protocol processing. RRU mainly completes radio frequency signal modulation and demodulation, amplifies the power of radio frequency analog signal, and transmits it to the antenna feeder.

It should be noted that the above-mentioned antenna device may also be referred to as an antenna.

In order to solve the problems mentioned in the background art, based on the network architecture shown in FIG. 1, as shown in FIG. 2A, the present application provides a beamforming method. The method can be executed by the first device or a component (such as a chip, a circuit, etc.) used in the first device. The first device may be an RRU, or BBU, or base station, or the like.

The method includes the following steps:

Step 201a: Obtain the compensation value corresponding to the first information from the antenna device.

Step 202a: Obtain a first weight for beamforming corresponding to the first information from the first device.

Step 203a: According to the compensation value and the first weight value, a second weight value for beamforming corresponding to the first information is determined.

Based on the above solution, the compensation value is stored in the antenna device, and the first weight value is stored in the first device. The compensation value corresponding to the first information can be used to compensate the first weight value for beamforming corresponding to the first information. In this way, the second weight value used for beamforming is obtained, which improves the accuracy of the weight value, and further improves the accuracy of beamforming.

Further, in the prior art (such as 4G communication), there is a solution in which the weights used for beamforming are stored in the antenna device. However, because the design of broadcast channels, control channels or dedicated channels in 5G is more flexible, resulting in more beams, and each version may also be refreshed, this kind of fixed beamforming weights are preset in the antenna device. The method may not meet the demand. On the other hand, because 5G broadcast channels, control channels, or dedicated channels support beam scanning, it is necessary to define the beam direction, scanning range, etc., and these values are configurable, if the beamforming weights are also preset Considering this parameter will result in a very large number of beamforming weights that need to be stored, which will result in insufficient storage space. In other words, the method of directly storing the weights for beamforming in the antenna device is not suitable for 5G communication. Therefore, in the embodiment of the present application, when the initial weight corresponding to the first information for beamforming is stored in the first device, and the compensation value corresponding to the first information is pre-configured in the antenna device, the antenna device can also be saved.

Step 201b: Obtain the compensation value corresponding to the first information from the antenna device.

Step 202b: Obtain a first weight for beamforming corresponding to the first information from the antenna device.

Step 203b, according to the compensation value and the first weight, determine a second weight for beamforming corresponding to the first information.

It should be noted that the embodiment of the present application does not limit the execution sequence between the foregoing step 201b and step 202b.

Based on the above solution, both the compensation value and the first weight value are stored in the antenna device. The compensation value corresponding to the first information can be used to compensate the first weight value for beamforming corresponding to the first information, so as to obtain the second weight value for beamforming, which improves the accuracy of the weight value, and then Improve the accuracy of beamforming.

In order to solve the problems mentioned in the background art, based on the network architecture shown in FIG. 1, as shown in FIG. 2C, this application provides yet another beamforming method. The method can be executed by the first device or a component (such as a chip, a circuit, etc.) used in the first device. The first device may be an RRU, or BBU, or base station, or the like.

The method includes the following steps:

Step 201c: Obtain identification information of the antenna device.

The identification information of the antenna device may be the ID of the antenna device.

Step 202c: Acquire the compensation value corresponding to the antenna device under the first information from the first device according to the identification information of the antenna device.

Step 203c: Obtain the first weight corresponding to the first information for beamforming from the first device.

Step 204c: According to the compensation value and the first weight value, a second weight value for beamforming corresponding to the first information is determined.

It should be noted that the above step 203c can be performed in any step before step 204c.

Based on the above solution, the compensation value and the first weight value are both stored in the first device, and the compensation value corresponding to the first information can be used to compensate the first weight value for beamforming corresponding to the first information to obtain The second weight value used for beamforming improves the accuracy of the weight value and further improves the accuracy of beamforming.

Based on the embodiment corresponding to FIG. 2C, it can be applied to antenna devices that are already in use and do not store weights or compensation values.

Among them, the electrical downtilt angle is the downtilt angle adjusted electronically, the digital downtilt angle is the downtilt angle adjusted by digital signals, and the mechanical downtilt angle is the downtilt angle adjusted mechanically. Alternatively, the electronic downtilt angle can be understood as the first device after inputting the digital signal into the antenna, it also needs to divide the digital signal into multiple parts through a phase shifter inside the antenna, and then input multiple antennas one by one. The digital downtilt angle can be understood as the first device inputs multiple set digital signals into multiple antennas in a one-to-one correspondence, and it can be set through the multiple antennas without processing by the phase shifter inside another antenna. The downtilt angle of the beam.

As an example, the antenna device stores information as shown in Table 1, for example.

And multiple antenna sub-arrays in the vertical direction, each sub-array corresponds to one antenna physical port. Alternatively, an antenna device may include an antenna sub-array that provides horizontal degree of freedom for beamforming and an antenna sub-array that can provide vertical degree of freedom for beamforming.

That is, in the embodiment of the present application, for an antenna physical port, a compensation value is used to perform weight compensation, that is, after the first weight corresponding to the antenna physical port is compensated by the compensation value, the second weight is obtained.

Wherein, each compensation value in a set of compensation values may include a phase compensation value, or an amplitude compensation value, or include a phase compensation value and an amplitude compensation value.

It should be noted that Table 1 is only an example. In practical applications, the corresponding relationship between the first information and the compensation value can be set as required. For example, the first information includes only frequency band, downtilt angle, azimuth angle and antenna physical port, or only downtilt angle, azimuth angle and antenna physical port, or only frequency band, frequency point, azimuth angle and antenna physical port, or only Downtilt angle, azimuth angle, etc.
