Description

Technical Field

[0001] The present disclosure relates to the field of phased array phase shifting, and in particular, to a method and device for phased array fast phase shifting control beam configuration. Background Art

[0002] With the rapid development of wireless communication, phased array technology has shown great application potential in fields such as radar and communication due to its beamforming ability. With the popularization of millimeter-wave 5G technology, phased array technology is facing more and more challenges. Among them, the demand for phased array antennas to cover a larger range is gradually increasing. Currently, 5G base stations use a large number of antenna units to improve the coverage rate. Some phased array systems support up to 2000 units or even higher. The increase in the number of antenna units leads to a decrease in the beam width, and more beam positions are required for the same scanning angle. At the same time, each beam position may require a different beam shape, so the configuration also needs to be modified. To ensure fast switching between different beam positions, this poses a great challenge to the beam configuration time, which requires the phased array system to provide a lower latency during beamforming and beam configuration processes.

[0003] There are two existing beam configuration methods. One is to control the corresponding channels through different independent chips to implement functions such as signal amplification, phase shifting, and gain change. These chips are controlled by independent control lines. The host computer is connected to these control lines and issues phase shifting, attenuation, and other instructions to each chip through serial communication to achieve changes in beam position and shape. The time required for each chip to communicate serially alone in this method is relatively long. Assuming that the phase of each channel requires N bit control and the attenuation requires M bit control, and the number of antenna units is CH, then the total serial communication duration is (N + M)*CH bit, and the amount of data transmitted during the beam configuration process is also large. Another method is to integrate multiple channels on a single chip and build a static random access memory in the chip to store the beam table. The beam table stores beam phase / gain settings. When a row number is sent to the phased array, the corresponding beam phase / gain settings are obtained from the beam table according to this row number. In this way, the beam setting time can be shortened. However, the number of beams supported by the beam table is limited. The more beams there are, the larger the beam table, resulting in a significant increase in the chip area. If the beam configuration exceeds the number of beams pre-stored in the beam table, the beam table needs to be reloaded, which will cause a large delay for large phased array arrays.

[0052] In view of the problems in the background art, the embodiments of the present disclosure provide a phased array fast phase shift control beam configuration method and device. Specifically, the phased array fast phase shift control beam configuration method is applied to a phased array chip. The phased array chip integrates multiple channels and includes a phase shift memory and a gain variable memory. The beam configuration method specifically includes: receiving multiple sub-array phase shift control frames in parallel and obtaining the beam direction factor and the initial calibration state value of each channel therefrom; calibrating each channel according to the initial calibration state value of each channel to obtain the phase calibration state and the gain compensation state of each channel; determining the position coordinates of each channel according to the reference coordinates of each antenna unit and the relative coordinates of each channel; calculating the phase state of each channel according to the position coordinates of each channel, the beam direction factor, and the phase calibration state of each channel and rounding; searching for the phase shift state number of each channel in the phase shift memory according to the rounded phase state of each channel; searching for the gain change state number of each channel in the gain variable memory according to the gain compensation state of each channel; and configuring the corresponding phase shift state number and gain change state number for each channel to implement beam configuration.

[0053] The phased array fast phase shift control beam configuration method and device provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings through specific embodiments.

[0054] Figure 1 The flowchart of a phased array fast phase shift control beam configuration method provided by the embodiments of the present disclosure is shown. Method 100 is applied to a phased array chip. The phased array chip integrates multiple channels and includes a phase shift memory and a gain variable memory. Among them, one channel corresponds to one antenna unit. Method 100 includes the following steps:

[0055] S110, receive multiple sub-array phase shift control frames in parallel and obtain the beam direction factors and the initial calibration states of each channel therefrom.

[0056] In some embodiments, the structure of the sub-array phase shift control frame is as Figure 2 shown. The sub-array phase shift control frame includes:

[0057] CSB signal, SCLK signal, SDI signal, SDO signal, and LDB signal; wherein,

[0058] the CSB signal is used to determine the channels that need to be calibrated and remains at a low level during the working state;

[0059] the SCLK signal is the clock signal of the phased array chip;

[0060] the SDI signal includes beam direction factors (f1, f2), the initial calibration states of the channels determined by the CSB signal, and a frame header. Among them, f1 and f2 are floating-point numbers, generally 32-bit data, or can be double-precision floating-point numbers, generally 64-bit data. And f1 and f2 are not limited to signed floating-point numbers, and the precision of f1 and f2 is determined by the accuracy requirement for the beam position;

[0061] Further, according to the SPI protocol, the frame header in the SDI signal is set to 011001000;

[0062] the SDO signal is used to enable the phased array chip to receive the beam direction factors in the SDI signal and the initial calibration states of the channels determined by the CSB signal, and is in a high-impedance state during the working state;

[0063] the LDB signal is used to configure the phase shift states and gain change states of the channels determined by the CSB signal and remains at a high level during the working state. In addition, the LDB signal can only become high level after 1 clock cycle after it becomes low level.

[0064] In some embodiments, regardless of the number of channels, as long as the frame header, the initial calibration states, and the beam direction factors in the SDI signal of each sub-array phase shift control frame are configured, beam configuration can be performed. Compared with the prior art, the configuration time is greatly saved, and moreover, any number of beams can be configured without pre-storing a beam table, greatly saving storage space.

[0065] In some embodiments, the beam direction factors are calculated by the following method:

[0066]

[0067] wherein, f1 and f2 respectively represent the beam direction factor in the x direction and the beam direction factor in the y direction, dx 、d y respectively represent the spacing between adjacent antenna elements in the x - direction and the spacing between adjacent antenna elements in the y - direction, M represents the preset maximum number of phase - shift states, the preset maximum number of phase - shift states covers a 360 - degree phase - shift range, λ is the wavelength corresponding to the operating frequency band of the phased - array antenna, θ, respectively represent the off - axis angle and the rotation angle of the phased - array antenna;

[0068] Furthermore, the off - axis angle of the phased - array antenna is defined as the angle between the antenna array plane and the positive direction of the Z - axis, and the rotation angle is defined as the counter - clockwise angle in the XOY plane with respect to the positive direction of the X - axis; among them, the positive direction of the Z - axis is defined as the transmission direction of the beam when the phased - array antenna emits a beam, that is, the antenna normal direction. Looking from the antenna normal direction, the direction horizontally to the left is defined as the positive direction of the X - axis, the direction vertically downward is defined as the positive direction of the Y - axis, and the coordinate origin is located at the corner of the antenna array plane;

[0069] Furthermore, the off - axis angle and the rotation angle of the phased - array antenna are calculated respectively by the following formulas:

[0070] θ = tan -1 {sqrt[tan(α)*tan(α)+tan(β)*tan(β)]}

[0071]

[0072] where α and β respectively represent the azimuth angle and the elevation angle of the phased - array antenna.

[0073] In some embodiments, the calculated f1 and f2 are more matched with the phased - array chip and have higher accuracy.

[0074] S120, calibrate each channel according to the initial calibration states of each channel to obtain the phase calibration state and the gain compensation state of each channel.

[0075] In some embodiments, considering actual manufacturing tolerances (such as errors introduced during the feeding network and antenna processing in the phased - array system, errors introduced during the assembly of each component in the phased - array system), mutual coupling between antenna elements, and non - ideal phase - shift / attenuation characteristics of the phase shifters / attenuators in the phased - array system, etc., a gain compensation state is introduced to compensate the phase state of the corresponding channel.

[0076] In some embodiments, the obtaining of the phase calibration state and the gain compensation state of each channel includes:

[0077] Through a multiplexer, corresponding phase calibration states of each channel are selected from pre-stored phase calibration states according to the actual working conditions of each channel, and corresponding gain compensation states of each channel are selected from pre-stored gain compensation states; wherein, the phase calibration states may be related to the temperature of the phased array chip, the operating frequency of the phased array chip, and the external environment.

[0078] Further, the pre-stored gain compensation states correspond one-to-one with M phase shift states.

[0079] In some embodiments, generally, the default phase calibration state is the 0 state.

[0080] S130. Determine the position coordinates of each channel according to the reference coordinates of each antenna element and the relative coordinates of each channel.

[0081] In some embodiments, the reference coordinates of each antenna element respectively represent the relative position coordinates of the phased array chip with respect to each antenna element.

[0082] The relative coordinates of each channel respectively represent the position coordinates of each channel with respect to the phased array chip.

[0083] Further, if the position coordinates of the channel are represented by (i,k), then:

[0084] (i,k) = (ibase,kbase) + (δi,δk)

[0085] Wherein, ibase and kbase respectively represent the relative position of the phased array chip with respect to the antenna element corresponding to this channel in the x direction and the relative position of the phased array chip with respect to the antenna element corresponding to this channel in the y direction, and δi and δk respectively represent the position of this channel with respect to the phased array chip in the x direction and the position of this channel with respect to the phased array chip in the y direction.

[0086] For antenna elements with regular structures, the spacing between adjacent channels is the same, so the relative coordinates of each channel are fixed values. Therefore, if it is necessary to configure the beams of several array antennas, and these array antennas are all composed of antenna elements with regular structures, then when configuring the beams of each array antenna, only (ibase,kbase) needs to be changed according to the reference coordinates of each antenna element in the array antenna, and (δi,δk) corresponding to each channel of each antenna element in the array antenna does not need to be changed, reducing the configuration content.

[0087] S140. Calculate the phase states of each channel and round them according to the position coordinates of each channel, the beam direction factor, and the phase calibration states of each channel.

[0088] In some embodiments, calculating the phase states of each channel according to the position coordinates of each channel, the beam direction factor, and the phase calibration state of each channel includes:

[0089] Phase_state(i,k) = i*f1 + k*f2 + PH_ADJ

[0090] where Phase_state(i,k) represents the phase state of the channel with position coordinates (i,k), i and k respectively represent the position of the channel in the x direction and the position of the channel in the y direction, and PH_ADJ is the phase calibration state of the channel.

[0091] In some embodiments, there is no limitation on the method of rounding the phase states of each channel.

[0092] S150, according to the rounded phase states of each channel, look up the phase shift states of each channel in the phase shift memory.

[0093] In some embodiments, the phase shift memory is a static random access memory, and this memory stores the phase shift states of each channel.

[0094] S160, according to the gain compensation state of each channel, look up the gain change states of each channel in the gain variable memory.

[0095] In some embodiments, the gain variable memory is another static random access memory, and this memory stores the gain change states of each channel. The gain change states of each channel are respectively equal to the sum of the gain compensation state of each channel and the preset initial gain state of the same channel;

[0096] Furthermore, by adjusting the gain change states of the channels, the adjustment of the channel amplitude is realized. Due to the orthogonality of the phase and amplitude in the channels, and the amplitude is mainly related to beamforming (i.e., mainly related to the position of the phased array chip) and has nothing to do with the phase, so the preset initial gain states of each channel can be set arbitrarily according to the beam shape information carried in the beam direction factor, that is, the preset initial gain states of each channel are arbitrary values.

[0097] In some embodiments, the phase calibration state of the same channel corresponds one-to-one with the phase state, the rounded phase state, the phase shift state, the gain compensation state, and the gain change state respectively.

[0098] S170, configure the corresponding phase shift states and gain change states for each channel to achieve beam configuration.

[0099] In some embodiments, method 100 further includes:

[0100] If it is necessary to configure the phase shift state number and gain change state number of each channel simultaneously, then while receiving the phase shift control frames of each sub-array, a command frame will also be received, and the phase shift state number and gain change state number of each channel will be configured simultaneously according to the command frame.

[0101] According to an embodiment of the present disclosure, the phased array fast phase shift control beam configuration method is applied to a phased array chip. The phased array chip integrates multiple channels and includes a phase shift memory and a gain variable memory. The beam configuration method specifically includes: receiving multiple sub-array phase shift control frames in parallel and obtaining the beam direction factor and the initial calibration state value of each channel therefrom; calibrating each channel according to the initial calibration state value of each channel to obtain the phase calibration state and gain compensation state of each channel; determining the position coordinates of each channel according to the reference coordinates of each antenna unit and the relative coordinates of each channel; calculating the phase state of each channel according to the position coordinates of each channel, the beam direction factor, and the phase calibration state of each channel and rounding it; looking up the phase shift state number of each channel in the phase shift memory according to the rounded phase state of each channel; looking up the gain change state number of each channel in the gain variable memory according to the gain compensation state of each channel; configuring the corresponding phase shift state number and gain change state number for each channel to achieve beam configuration. In this way, the beam configuration time and system delay of a large-scale array surface can be significantly reduced, the phase and amplitude of the channels can be accurately controlled, the beam pointing can be quickly and accurately changed, and storage space can be saved.
