For example, it can be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, an industrial control (industrial control) ), machine type communication (MTC) terminals, customer premise equipment (CPE), wireless terminals in self-driving (self-driving), telemedicine (remote medical) Wireless terminal, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc. The embodiments of the present application do not limit application scenarios.

For ease of understanding, the following will briefly introduce the basic concepts involved in the embodiments of the present application.

Beamforming is a key technical solution to adjust the beam pointing. It mainly uses the principle of wave interference to make the main lobe of the transmitted wave align with the direction of the target terminal equipment by changing the signal amplitude and phase parameters on each antenna element. The zero point and side lobes are aimed at other undesired users, thereby enhancing the received signal of the target terminal equipment, reducing the interference between users, and finally improving the system capacity. In addition, the direction of the antenna radiation can be realized by changing the relative delay between the wave sources, and the change of the relative position between the transmitter and the receiver can be tracked in real time.

The above-mentioned antenna array element refers to the antenna radiating unit that constitutes an antenna array. Two or more single antennas operating at the same frequency are fed and spatially arranged according to certain requirements to form an antenna array, also called an antenna array. The antenna array may be single-frequency or multi-frequency, may be a single-polarized antenna, or may be a multi-polarized antenna, which is not limited in this embodiment of the present application.

Beamforming includes digital beamforming (DBF) and analog beamforming (analog beamforming, ABF). DBF can provide more accurate beamforming, but requires each antenna port to have an independent baseband processing module and high-power analog-digital/digital-analog (AD/DA) conversion module, which As a result, the complexity, cost, and power consumption of the hardware structure are all higher; ABF is simpler and lower in cost than DBF, but has lower shaping flexibility and loses system performance. In order to integrate the advantages and disadvantages of the two forming methods, ABF and DBF are combined, that is, the beamforming with adjustable amplitude and phase at the RF end and the digital beamforming of the baseband are combined, which is called hybrid beamforming (HBF). ). HBF splits the full DBF in the traditional MIMO system into DBF at the baseband end and ABF at the radio end, that is, firstly, the different data streams are mapped to the corresponding radio frequency links through the DBF matrix at the baseband end, and then different radio frequencies are mapped by the ABF matrix at the radio end. Data streams on the link are mapped to different antenna elements.

The network device in this embodiment of the present application adjusts the width and direction of the waveform according to dynamic change factors such as the location of the terminal device and the channel state, so as to form a narrow beam aimed at the terminal device. The dynamic beam directed to the terminal equipment is obtained by assigning different beam weights to the array elements. The beam weight refers to a vector calculated based on downlink channel characteristics, which is used to change the beam shape and direction.

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic structural diagram of the communication system of the present application. As shown in Figure 1, the communication system includes: an antenna, a feeder, a pole, an optical fiber, a remote radio unit (RRU), a base band unit (BBU), etc., wherein the antenna includes a control drive module, The antenna is connected to the RRU through a feeder, and the RRU and the BBU are connected through an optical fiber.

FIG. 2 shows an HBF antenna system based on a digital phase shifter to control analog weights applied by an embodiment of the present application, where the system includes a BBU, an RRU, and an antenna. The beam weights of the HBF antenna system are generally divided into two types: baseband weights and analog weights. The prior art weight processing method for the HBF antenna system is as follows: the network device calculates the dynamic beam weight based on the downlink channel characteristics, wherein the baseband weight is sent by the BBU to the RRU, and the RRU processes the signal and maps it to the antenna port; The analog weights are sent by the RRU to the antenna control driving module, where the control module controls the digital phase shifter to output different analog weights through the driving module (as shown in the dotted box in Figure 2). The final weight is obtained by weighting the baseband weight and the analog weight, and the radiating unit forms a narrow beam directed to the target terminal device. The prior art calculates beam weights only based on downlink channel characteristics, and does not take into account information that cannot be obtained when estimating downlink channel characteristics but affects user experience or network performance. Therefore, the accuracy of beam weights in the prior art is not taken into account. Still unable to meet the needs of NR services or networks. It should be understood that the ellipses in FIG. 2 represent multiple numbers, and the present application does not make any limitation on the number of radio frequency signal lines and radiation units.

In addition, the inside of the antenna includes an antenna connector, a control connector, a control drive module, a radio frequency feeding network, a radiation unit, and the like. The antenna is located in the radome, the radiation unit and the reflector are assembled into at least one independent array, the frequencies of the radiation units may be the same or different, and the radiation units are usually placed above the reflector. The antenna arrays receive or transmit RF signals through their respective feed networks. The antenna control and drive module (including the switch control module and the drive module) is used to receive and execute the control commands from the network equipment, and control the adjustable microwave switch on the antenna digital phase shifter through the drive module to change the beam weight. There is a processor (central processing unit, CPU) on the control module, which can realize the communication with the network equipment, and realize the control of the microwave switch through the driving module. The feeder network may include a phase-shift network, and there may also be modules such as combiners, filters, and power dividers to extend performance. The feed network can realize different analog weights by controlling the driving module to control the digital phase shifter.

It should be understood that FIG. 2 is only an example of a system to which the method provided by the embodiment of the present application can be applied, and FIG. 2 does not limit any other systems to which the method can be applied.

It can be understood that the antenna mentioned in the embodiments of this application may be a traditional network device antenna, or a millimeter-wave antenna, and may also be installed in a WIFI router with multiple antennas, or installed on a mobile phone, etc. The embodiment does not limit the quantity, form, internal structure and installation position of the antennas, and FIG. 1 and FIG. 2 are only examples.

In order to meet the requirements of new services, an embodiment of the present application provides a wireless communication method. On the basis of determining the analog weight according to the characteristics of the downlink channel, the information that cannot be obtained when estimating the characteristics of the downlink channel but affects the user experience or network performance is further obtained. Improve the accuracy of dynamic beam weights.

As an example and not a limitation, the information that can be obtained by a network device when estimating downlink channel characteristics involved in this embodiment of the present application includes channel measurement and interference measurement, such as signal to interference plus noise ratio (SINR) and reference Signal receiving power (reference signal receiving power, RSRP), where SINR refers to the ratio of the strength of the useful signal received by the signal receiver to the strength of the received interference signal (noise and interference), and RSRP refers to a certain symbol The average value of the signal power received on all resource elements (REs) that carry reference signals within.

There are two different methods for obtaining the characteristics of the downlink channel: one is that the network device calculates the characteristics of the corresponding downlink channel according to the reciprocity principle by measuring the channel sounding reference signal (SRS) of the uplink channel of the terminal device; One means that the terminal device measures the downlink channel state information-reference signal (CSI-RS), and reports the measurement result to the network device through the pre-coding matrix indication (PMI). Downlink channel characteristics are estimated based on the PMI.

As an example and not a limitation, the information (that is, the preset antenna parameters) that cannot be obtained when estimating downlink channel characteristics involved in the embodiments of the present application but affects user experience or network performance (that is, antenna preset parameters) includes passive intermodulation (passive intermodulation, PIM) parameters , signal propagation delay parameters, zero fill parameters, insertion loss parameters, device power consumption parameters, etc. These parameters are preset in the factory parameters of the antenna, and can be measured or estimated in advance for different simulation weights and written into the factory parameter table. The analog weights correspond to these antenna preset parameters, and different analog weights are obtained by different states of the adjustable microwave switches on the digital phase shifter, and different states of the digital phase shifter correspond to the above-mentioned different antenna preset parameters. Since these antenna preset parameters cannot be obtained, the user experience or network performance is affected to a certain extent. For example, during the game, the user may experience screen freezes and other phenomena, the user's game experience is poor, and the signal propagation delay parameter affects the user. An important parameter of game latency experience.

Below, some antenna preset parameters are introduced:

PIM, caused by the nonlinear properties of various passive devices in communication and electronic systems. In high-power, multi-channel systems, the nonlinearity of these passive devices produces higher harmonics relative to the operating frequency, which in turn mix with the operating frequency to create a new set of frequency combinations, the end result of which is A set of useless spectrum components will be generated and affect the normal operation of the communication system.

Signal propagation delay refers to the time it takes for an electromagnetic signal to propagate a certain distance in the transmission medium, that is, from the sender sending data to the receiver receiving the data (or sending an acknowledgment frame from the receiver, to the sender receiving the acknowledgment) frame) total elapsed time.

Insertion loss refers to the attenuation of the level after the signal passes through a module (mainly passive modules, including cables, connectors, filters, mixers, etc.).

Device power consumption, the loss of device power, refers to the difference between the input power and the output power of the device. In a circuit, usually refers to the thermal energy dissipated in the components. On the switch circuit of the digital phase shifter, different states of the switch correspond to different power consumption.

As an example and not a limitation, the simulation weight table involved in the embodiment of the present application is shown in Table 1. The internal storage unit of the antenna stores all the analog weights that can be output by the digital phase shifter in the antenna. The network device calculates the dynamic beam weights based on the downlink channel characteristics, and sends control commands to the antenna control driving module through the RRU, wherein the control module controls the digital phase shifter to output different analog weights through the driving module. In this process, based on historical data, the embodiment of the present application stores all the analog weights that can be output by the antenna control and driving module into the storage unit of the antenna. In other words, at least one of the simulation weights delivered by the network device through the RRU is the same as multiple simulation weights in the antenna storage table.

Each analog weight corresponds to a beam, a set of information that can be obtained when estimating downlink channel characteristics, and a set of antenna preset parameters. At the same time, each beam has its fixed shape, and the analog weight 1-analog weight 12 corresponds to the beam 1-beam 12. Beam 1 to beam 12 are classified according to the similarity of the antenna radiation pattern waveforms corresponding to different analog weights. The degree of similarity can be understood as the degree of similarity of the beam shapes or the degree of coincidence of the beam shapes.

For example, Figure 3 shows the waveforms of two beams. The circumferential coordinate represents the spatial angle, and the radial coordinate represents the gain. In the figure, beam 1 and beam 2 are basically coincident, and there are only slight differences where the gain is small at some angles. , it can be considered that the requirement of similarity is met, that is, beam 1 and beam 2 are mutually similar beams or beams of the same type. The embodiments of the present application do not limit the specific value of the degree of similarity or the degree of coincidence, and those skilled in the art can flexibly set it according to the actual situation.

In this case, the simulation weight 1-simulation weight 12 are also classified accordingly, and the classification results are shown in Table 1. The difference between the SINR and RSRP corresponding to each two simulation weights in the same candidate weight set is preset at The range is related to the waveform similarity. In other words, when two beams are considered to be similar, the difference between the SINR and RSRP corresponding to their analog weights is within a certain range.

As an implementation manner, in Table 1, A represents the PIM parameter in the antenna preset parameters, B represents the propagation delay parameter in the antenna preset parameters, C represents the device power consumption parameter in the antenna preset parameters, a1- a12 is the value corresponding to A, b1-b12 is the value corresponding to B, and c1-c12 is the value corresponding to C.

It can be understood that the number of simulated weights is greater than or equal to the number of simulated weight sets.

It should be understood that Table 1 is only an example to assist in understanding the technical solutions of the present application, and the embodiments of the present application do not limit the meaning and the quantity of parameters represented by the letters of Table 1.

For example, in this step, if the control signaling indicates that the first analog weight to be output is the analog weight 3 in Table 1, the candidate weight set is determined to be the candidate weight set #1, that is, the first analog weight in Table 1. a row.

Step 104: The antenna control and driving module selects an analog weight corresponding to the minimum propagation delay parameter in the determined candidate weight set #1 (an example of the second analog weight).

Taking the analog weight 5 in the candidate weight set #2 as an example, the corresponding propagation delay parameter value is b5, and the device power consumption parameter is c5. Calculate (b6-b5)×k+(c6-c5)×h value, the other simulated weights in the candidate weight set #2 also perform the same calculation as the simulated weight 6 in turn (that is, replace b5 and c5 in the formula with b6, b7, b8 and c6, c7, c8), Compare the calculation results of all candidate weights, and obtain the corresponding simulation weights when the calculation results are greater than or equal to zero. If there is one weight that satisfies the condition, the simulation weight is determined to be the second simulation weight; if there are multiple weights that satisfy the condition, the simulation weight corresponding to the maximum calculation result is selected to be the second simulation weight value.

For example, assuming that the propagation delay and device power consumption corresponding to the first analog weight are 5ms and 5w respectively, and the propagation delay and device power consumption corresponding to a certain candidate weight are 3ms and 6w respectively, set the propagation delay parameter of The weight is 70%, and the weight of the power consumption parameter of the device is 30%, then (5-3)×70%+(5-6)×30%=1.1 can be calculated, if the value is greater than or equal to 0, the candidate can be determined The weight is the second simulation weight.
