Description

technical field

The invention relates to the technical field of mobile communication, in particular to a smart antenna device and method supporting independent electrical adjustment of different systems.

Background technique

With the development of mobile communication technology, in addition to the 3G network under construction such as TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access), there will also be TD-LTE (Time Division-Long Term Evolution, long-term evolution of time-division synchronization) 4G network. In this case, there will inevitably be a network development situation where multiple standards coexist. At present, various technical standards have independent antenna feeder systems, and the frequency bands used are also very different. However, due to the existence of multi-standard networks of multiple operators, and considering the subsequent evolution, the number of antenna feeders in the future will be very alarming. If multi-operator network construction is considered, this situation will lead to extremely tight antenna resources (such as base station towers, poles, outdoor cable racks, etc.), and at the same time, multiple antennas working under different systems will bring additional The problems of electromagnetic compatibility and mutual influence will greatly delay the construction progress.

In addition, in the technical development of LTE, especially in TD-LTE and WiMAX systems, multi-antenna technology has become an important means to improve the performance of LTE network in the future. Therefore, there is also an urgent need for a multi-antenna device that can independently support the LTE network.

The main disadvantages of this approach are:

1. Existing dual-polarization smart antenna equipment generally adopts the structure of ±45-degree radiation unit arrangement. The technology is mature and stable in the AB frequency band, but it cannot cover the C frequency band, so it cannot support TD-SCDMA system and TD-LTE The system is used for antenna feeder.

2. Two antennas need to be designed to support the LTE system and the 3G system respectively, and the two antennas carry two RRUs (Radio Remote Unit, radio frequency remote module) respectively, thus occupying more antenna resources.

3. Based on different frequency bands, the inclination cannot be completely independently optimized and adjusted according to the coverage differences caused by the frequency bands. It is relatively difficult to realize electric adjustment in the entire wide frequency band, and it will reduce the performance of antenna equipment to a certain extent.

To sum up, the existing smart antenna equipment cannot support different systems (such as TD-SCDMA system and TD-LTE system) to use common antenna feeder, occupy a lot of antenna resources, and the performance of the antenna equipment is low.

The control module is used to separately control the phase shifters included in the phase shifter group to adjust the phase shift amount, so that the total phase shift amount corresponding to each phase shifter meets the working requirements of the corresponding system of the phase shifter group.

More specifically, in one embodiment of the present invention, each smart antenna array includes:

Two sets of radio frequency ports with a set number are used to respectively support the sending and receiving of signals meeting the first working frequency band and the sending and receiving of signals meeting the second working frequency band.

In order to better understand the technical solutions provided by the embodiments of the present invention, the following takes the first system as the TD-SCDMA system (hereinafter referred to as the TD system) and the second system as the LTE system as an example. The antenna device is described in more detail:

In order to realize the independent electrical adjustment of parameters such as the downtilt angle and beam pointing of the TD system and the LTE system without increasing the number of radiation units in the embodiment of the present invention, as shown in Figure 2, the smart antenna device provided by this embodiment adopts two sets of Phase shifter bank, where:

The first phase shifter group 201 is used to support the AB frequency band, wherein the frequency range of the A frequency band is: 1880MHz-1920MHz, and the frequency range of the B frequency band is: 2010MHz-2025MHz;

The second phase shifter group 202 is used to support the C-band, and its frequency range is: 2300MHz-2400MHz.

specifically:

The first phase shifter group 201 is composed of N mutually independent phase shifters, where N is the number of smart antenna arrays. Each phase shifter has a corresponding working frequency band and electronic control function. In the corresponding working frequency band, the phase shift amount of N mutually independent phase shifters can be adjusted electronically through the control module to meet the needs of each antenna array group. The sum of the working frequency bands corresponding to each phase shifter satisfies the first working frequency band corresponding to the TD system, thereby realizing the electric adjustment function of the working frequency band of the TD system (that is, the AB frequency band). Specifically, each phase shifter corresponds to an antenna array, and the corresponding relationship between the phase shifter and the antenna array can be flexibly set.

The specific composition principle of the second phase shifter group 202 is basically the same as that of the first phase shifter group 201. The phase shift amount of N mutually independent phase shifters is adjusted by the electronic control of the control module, and the total working frequency band corresponding to each phase shifter The second working frequency band corresponding to the LTE system is satisfied, so as to realize the electric adjustment function of the working frequency band of the LTE system (that is, the C frequency band).

The control modules included in the first phase shifter group 201 and the second phase shifter group 202 are used to respectively control the phase shift amount of each phase shifter in the phase shifter group, so that the corresponding total phase of each phase shifter The amount of displacement meets the requirements for the downtilt angle of the working frequency band corresponding to the system where the phase shifter group is located.

The combiner group 203 is respectively connected to each phase shifter in the first phase shifter group 201 and the second phase shifter group 202, specifically, the number of combiners included in the combiner group is the same as the number of antenna arrays, That is, the number of phase shifters included in the first phase shifter group 201 or the second phase shifter group 202 is the same. Each combiner is respectively connected to one phase shifter in the first phase shifter group 201 and one phase shifter in the second phase shifter group 202 . TD and LTE systems based on different frequency bands can be completely independent by combining the two signals (AB frequency band and C frequency band) independently adjusted by the two phase shifter groups into one, and then feeding it to the smart antenna array connected to it. Adjust and optimize the downtilt angle; and, each combiner included in the combiner group is connected to a group of smart antenna arrays included in the smart antenna array group, and is used to split the signal from the connected smart antenna array into two The signals are provided to the first phase shifter group 201 or the second phase shifter group 202 respectively, wherein: the working frequency band of each combiner covers the working frequency band of the TD system and the working frequency band of the LTE system.

The smart antenna array group 204 includes smart antenna arrays with the same number of combiners as the combiner group; and each group of smart antenna arrays is used to send signals processed from the combiners connected to it; Signals to the TD system and LTE system are sent to the combiner for processing.

In the embodiment of the present invention, the phase shifters in the first phase shifter group 201 and the second phase shifter group 202 may adopt the same technical standard but different frequency bands, or may adopt different technical standards and different frequency bands. The current common phase shifters mainly include three technical standards, namely gallium arsenide (GaAs) digital phase shifter, microelectromechanical system (MEMS) device phase shifter and ferrite analog phase shifter. in:

Gallium arsenide phase shifter is a way to change the total phase by using many switches with inconsistent delays, and the accuracy of the phase is controlled by the number of switches;

The phase shifter based on MEMS uses delay line technology to generate phase shift, and the phase shift amount is controlled by the delay amount provided by MEMS capacitor;

The thin-film ferrite material phase shifter (such as barium strontium titanate) has good controllability in a wide temperature range, and the capacitance can be adjusted through a voltage change, thereby changing the phase shift amount.

The phase shifters of the above three technical standards have their own advantages and disadvantages. For example, the gallium arsenide phase shifter is very small in size, about a few square millimeters, and the technology is mature and reliable, but the manufacture of gallium arsenide is one of the most expensive semiconductor manufacturing technologies. One, and special packaging is required, so the production cost is relatively high; the size of the MEMS phase shifter is also quite small, and the radio frequency loss is low, but due to the new technology, the reliability needs further verification; the size of the thin film ferrite phase shifter is very small , the control is simple, mature and reliable, but the material is more difficult to manufacture. In practical applications, the advantages and disadvantages of various technical standards can be comprehensively compared, and a phase shifter of an appropriate technical standard can be selected according to the requirements of the application.

The above-mentioned phase shifters and technical standards are only for reference, and other types of phase shifters that meet application requirements are also applicable to the embodiments of the present invention.

In the embodiment of the present invention, the above-mentioned combiner group 203 needs to be able to perform good synthesis of microwave signals in the ultra-wideband frequency band (for example, 1880MHz-2400MHz supporting the ABC frequency band). In a preferred embodiment of the present invention, a multi-tab Wilkinson combiner can be used to implement an ultra-wideband combiner. Through calculation and simulation, the three-branch multi-band Wilkinson combiner can cover the entire frequency band of 1880MHz-2400MHz. The three-branch Wilkinson combiner of different frequency bands can combine signals of specific frequency bands (such as A frequency band, B frequency band and C frequency band) into one channel, and has good reflection coefficient, port isolation coefficient, and transmission coefficient in the entire frequency band. Therefore, the three-branch Wilkinson combiner can synthesize microwave signals well in the ultra-wideband frequency band. In addition, in practical applications, the miniaturization of the internal combiner needs to be considered in order to reduce the increase in the volume of the antenna, such as using a microstrip combiner to reduce the volume.

The above combiner is only for reference, and other types of combiners that meet application requirements are also applicable to this embodiment of the present invention.

According to the technical solution provided by the embodiment of the present invention, the requirements for separate adjustment of the two systems can be realized without changing the size of the current broadband dual polarization. When the system in one of the frequency bands needs to adjust the antenna downtilt angle and other parameters, it can be adjusted electronically according to the required phase shift (the electronic control adjustment method of different phase shifters is different, for example, the gallium arsenide digital phase shifter is adjusted by adjusting the delay switch. Change the phase shift amount) each independent phase shifter in the phase shifter group corresponding to, and then obtain the required parameters such as the corresponding antenna downtilt angle in this frequency band. It can support LTE systems such as 2×2 MIMO, 4×2 MIMO, and 8×2 MIMO while supporting the TD system.

The smart antenna device provided by the embodiment of the present invention improves the existing antenna array in order to realize the broadband design of the antenna array covering 1880MHz to 2400MHz (that is, the ABC frequency band). In practical applications, considering the existing network structure, the present invention In a preferred embodiment, in order to achieve this goal, the spacing of the smart antenna array is reduced to 65mm, and the working frequency band of the smart antenna is broadened by correspondingly reducing the physical size of the unit oscillator and optimizing the structure of the oscillator.

According to the embodiment of the present invention, in order to enable the smart antenna device to support two systems, the radio frequency ports of the antenna are changed from the original 8 radio frequency ports located at the lower end of the antenna to the design of 16 radio frequency ports, while maintaining the same number of antenna arrays The premise is to support the frequency bands of the two systems; among them, the RF ports of the 8 antenna arrays are at the lower end of the antenna, the RF ports of the 8 antenna arrays are at the back of the antenna, and the 8 antenna RF ports at the lower end of the antenna and the 8 antennas at the back of the antenna The antenna radio frequency ports may share the same CAL port (that is, the calibration port), or may use separate CAL ports.

Further, if the integrated design of the RRU and the antenna is adopted in the TD system, the RRU is connected to the antenna through the blind insertion radio frequency interface on the back of the integrated antenna. Through the embodiment of the present invention, the 8 radio frequency ports located at the lower end of the antenna support the LTE system Corresponding working frequency band, the 8 radio frequency ports on the back of the antenna support the corresponding working frequency band of the TD system, or the 8 radio frequency ports on the lower end of the antenna support the corresponding working frequency band of the TD system, and the 8 radio frequency ports on the back of the antenna Support the working frequency band corresponding to the LTE system; according to the embodiment of the present invention, the working frequency band corresponding to the LTE system can also be supported through the blind insertion radio frequency interface on the back of the integrated antenna, so as to effectively solve the problem that the existing integrated antenna design scheme cannot evolve to LTE in the future The problem.

In terms of antenna design, the existing integrated antenna solution needs to design two antennas to support the TD system (based on A and B frequency bands) and the LTE system (based on C frequency band) respectively. At the same time, there are two RRUs on the back of the two antennas. This method takes up more space resources (for example, base station iron towers, poles, outdoor cable racks, etc.); the integrated antenna solution realized by the technical solution provided by the embodiment of the present invention only needs to design one antenna, through which The antenna can support the application of ABC three frequency bands at the same time, and can realize the use of two systems in different frequency bands at the same time, and the inclination angle can be adjusted independently between the two RRU devices, which is very convenient for network optimization.

As for the design change of the corresponding module, the difference between the smart antenna device provided by the embodiment of the present invention and the traditional antenna in the calibration network structure can be reflected through the comparison of Fig. 3 and Fig. 4. As shown in Fig. 3, it is the The schematic block diagram of the calibration network structure, as shown in Figure 4, is a schematic block diagram of the calibration network structure of the smart antenna device provided by the embodiment of the present invention, as can be seen from Figure 3, the traditional calibration network does not contain a combined circuit on each antenna array channel Therefore, it is impossible to support TD and LTE systems to completely independently adjust the tilt angle electronically, but the calibration network of the smart antenna device provided according to the embodiment of the present invention can support the independent electronic control adjustment of the two systems. Firstly, by adding a combiner to the internal feeder part of the antenna array, the array can realize RF processing in different frequency bands, and then add a phase shifter group to each antenna array channel to realize independent electric adjustment (see P-x, where x is respectively Represents 1 to 8, that is, 8 RF ports, P and P' represent AB frequency band signals and C frequency band signals respectively). For the calibration port part (see P-cal shown in the figure), two ports can also be separated through the combiner, which are used for separate calibration of the two frequency bands. This part may also be uncombined internally according to the situation, and only one port is reserved. Port, and then the two antennas outside the antenna are combined and shared.

The present invention aims at the 3G (such as TD-SCDMA) system that adopts smart antenna technology when the 4G (such as LTE, WiMAX) system adopts multi-antenna technology in the existing scheme and can not adjust the inclination angle completely independently; Issues such as coverage differences can be completely independently optimized and adjusted, which fundamentally solves the problem of integrating multiple antenna feeder systems and saves a lot of direct and indirect costs for network construction. At the same time, because the 3G system and other systems can adjust the inclination independently, it is beneficial to optimize the network separately. And compared with other system antennas, the size of the antenna changes less, which will not bring more additional difficulties to the construction.
