[0002] In current mobile communication systems represented by Long Term Evolution (LTE) and New Radio (NR), multi-antenna technology is used as a key technology for air interface transmission. Compared with single-antenna systems, multi-antenna systems can achieve better spectrum efficiency and throughput through space division multiplexing technology, so they have received widespread attention in recent years.

[0003] In a multi-antenna system, using space division multiplexing technology, the transmitter can transmit data to multiple users through different beams under the same time and frequency resources. In view of the heterogeneity of business requirements and machine channel conditions of different users, in order to optimize system performance, differentiated signal transmission measurements need to be implemented for each transmit beam.

[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application.

[0043] It should be noted that the terms "system" and "network" in the embodiments of the present invention can be used interchangeably. "Multiple" means two or more. In view of this, in the embodiments of the present invention, "multiple" can also be understood as "at least two". "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / ", unless otherwise specified, generally indicates that the previously associated objects are in an "or" relationship.

[0044] The embodiment of the present application provides a signal processing method, which is applied to the baseband module of the transmitting device, generates the baseband signal corresponding to each beam and obtains the power allocation information of each beam through the baseband module, and then sends the baseband signal and the power allocation information to the antenna module of the transmitting device, so that the antenna module performs weighted processing on the baseband signal based on the power allocation information to form a transmitting signal. Since the baseband module can obtain the service requirements of different users, the baseband module can determine the power allocation information of each beam according to the differences in user requirements, and realize the differentiated allocation of the transmission power of each beam. Therefore, compared with the average power allocation method on the antenna module side, this solution can provide a more refined power control strategy to optimize the transmission of the signal and improve the overall performance of the system. In addition, in the solution of the present application, the baseband module separates the baseband signal and the power allocation information and transmits them to the antenna module, so that the quantization error can be effectively reduced under the premise of a fixed number of quantization bits.

[0045] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: LTE system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, fifth generation (5G) mobile communication system or NR communication system and future mobile communication systems.

[0046] like Figure 1 As shown, Figure 1 This is a structural diagram of a communication system 10 applicable to the signal processing method of an embodiment of the present application. The communication system 10 may include a transmitting device 11 and a receiving device 12. The transmitting device 11 may include multiple antennas. The multiple antennas may be divided into multiple antenna groups, and each antenna group includes at least one antenna.

[0047] The transmitting device 11 can be any device with wireless transceiver functions or a chip that can be set in the device. The device includes but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (for example, Home evolved NodeB, or Home Node B, HNB), access point (AP) in wireless fidelity (WIFI) system, wireless relay node, wireless backhaul node, transmission point (TP) or transmission and reception point (TRP), etc. It can also be a gNB in ​​a 5G system, or it can also be a satellite or satellite base station in a satellite system.

[0048] The receiving device 12 may be, for example, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. The receiving device 12 in the embodiment of the present application may be a mobile phone, a tablet computer (Pad), a computer with a wireless transceiver function, or a wireless terminal used in scenarios such as virtual reality (VR), augmented reality (AR), industrial control, self driving, remote medical, smart grid, transportation safety, smart city, and smart home. It should be understood that the embodiment of the present application does not limit the specific technology and specific device form adopted by the receiving device 12.

[0049] Each group of divided antennas may be referred to as a sector of the transmitting device 11. For example, the antenna group may be designed to communicate with the receiving device 12 in a sector of the coverage area of ​​the transmitting device 11. When the transmitting device 11 communicates with the receiving device 12, the transmitting antenna of the transmitting device 11 may transmit signals using beamforming technology.

[0050] In the communication system 10, the transmitting device 11 and the receiving device 12 can use the Multiple Input Multiple Output (MIMO) technology for wireless communication. MIMO technology refers to using multiple transmitting antennas and receiving antennas in the transmitting device 11 and the receiving device 12 respectively, so that the signal is transmitted and received through the multiple antennas of the transmitting device 11 and the receiving device 12, thereby improving the communication quality. The MIMO technology can make full use of spatial resources and realize multiple transmission and multiple reception through multiple antennas. Without increasing the spectrum resources and antenna transmission power, the system channel capacity can be increased exponentially.

[0051] In a multi-antenna system, the transmitting device 11 can use the same time-frequency resources to transmit service data to different users in different beams. This technology is called space division multiplexing technology.

[0052] Please refer to the following Figure 2 , Figure 2 A flowchart of a signal processing method provided in an embodiment of the present application, the method is applied to a baseband module of a transmitting device, and the method comprises the following steps:

[0053] Step S110: Generate a baseband signal corresponding to each beam and obtain power allocation information of each beam.

[0054] The baseband module may refer to a baseband processing unit (Base Band Unit, BBU), which refers to the control center of the transmitting device, and is mainly used for baseband processing and controlling the transmitting device, such as channel coding, multiplexing, modulation, and spread spectrum. In an embodiment of the present application, the baseband module may also have a power allocation function. For example, the baseband module may dynamically adjust the transmission power of each beam according to the quality of the signal and the needs of the network to optimize signal coverage and reduce interference. The baseband module may also be responsible for the implementation of the beamforming algorithm. The specific implementation of the beamforming algorithm is not limited in the embodiment of the present application. In actual applications, different beamforming algorithms can be flexibly selected according to needs.

[0055] The baseband module can generate corresponding baseband signals for each beam. The baseband signal refers to the original signal that needs to be transmitted but has not been modulated. The baseband signal can be a downlink signal sent by the transmitting device to the receiving device, such as a downlink reference signal such as a cell common reference signal, a demodulation reference signal, and a channel quality measurement reference signal in the downlink. This application does not impose any special restrictions on the form of the baseband signal, and does not impose any special restrictions on the generation method of the baseband signal.

[0056] During the beamforming process, the baseband module can also control and schedule the power of multiple beams according to the capabilities of the transmitting equipment, so the baseband module can also obtain the power allocation information of each beam, and the power allocation information is used to adjust the transmission power of each beam.

[0057] Among them, the baseband signal and power allocation information are quantized using the corresponding set bit number. Quantization refers to converting analog signals into digital signals. The original baseband signal and power allocation information are analog signals, which can be achieved through the quantizer in the baseband module. The quantizer defines the quantization level or quantization step of the signal, and the quantization step determines the accuracy with which the signal can be represented.

[0058] It is understandable that the set number of quantization bits used by the baseband signal and the power allocation information may be different. For example, the number of quantization bits of the baseband signal is N, and the number of quantization bits used by the power allocation information is M. N and M can be the same or different, and can be selected according to actual conditions.

[0059] Step S120: Send the baseband signal and power allocation information to the antenna module of the transmitting device.

[0060] The baseband module determines the power allocation information and sends it to the antenna module, and then the antenna module performs weighted processing on the baseband signal based on the power allocation information to form a transmission signal.

[0061] In practical applications, the signal transmission process of a multi-antenna space division multiplexing system is roughly divided into four processing parts: signal generation, beam weight generation, signal weighting and signal transmission. The signal generation part is responsible for generating baseband signals of different beams, the beam weight generation part is responsible for calculating the beam weights that meet the requirements of different beam pointing, the signal weighting part uses the beam weights to perform weighted operations on the baseband signals to generate weighted transmission signals, and the signal transmission part is responsible for mapping the weighted transmission signals to different antennas and completing signal transmission. The above four processing parts are the logical division of the signal transmission steps of the multi-antenna space division multiplexing system. In the actual multi-antenna space division multiplexing products, these four processing parts may be distributed in different hardware modules. For example, one distribution method is that the signal generation part is carried by the baseband module, and the beam weight generation, signal weighting and signal transmission parts are carried by the antenna module (this is usually because the baseband module and the antenna module are produced by different manufacturers).

[0062] Therefore, if the baseband module and the antenna module are produced by different manufacturers, the baseband module may not support directly sending the power allocation information to the antenna module. In this case, the antenna module either performs average power allocation or the baseband module directly applies the power allocation information to the baseband signal to form a new baseband signal to be transmitted to the antenna module. However, doing so may result in large quantization errors.

[0063] In the embodiment of the present application, the baseband module does not need to directly allocate power to the baseband signal, and the purpose of doing so is to reduce the loss of accuracy. For example, the baseband signal is represented as x, and the power allocation information is represented as p. If the baseband signal is power allocated in the baseband module, it can be represented as the baseband module multiplying the baseband signal and the power allocation information, such as obtaining px, and then quantizing px to a set number of bits and transmitting it to the antenna module. Since p and x are in a multiplication relationship, the value range of px is larger than that of x. When the number of quantization bits remains unchanged, the quantization error caused by the quantization truncation will increase, resulting in a significant decrease in the accuracy of the quantized signal.

[0064] To improve this problem, in the embodiment of the present application, the communication protocol between the baseband module and the antenna module can be changed so that the baseband module can support the transmission of power allocation information to the antenna module. The baseband module quantizes the baseband signal and the power allocation information respectively, and then transmits them to the antenna module. That is, in this solution, the baseband module separates x and p and then transmits them to the antenna module.

[0065] Here is a simple example to illustrate the impact of the two implementation methods on quantization error.

[0066] Assume that the baseband signal is x, its amplitude ranges from -1 to 1, and the power allocation information p ranges from 0 to 100. If two beams are to be transmitted, the ideal values ​​of the baseband signals of the two beams are x0=0.8 and x1=0.9, respectively, and the ideal values ​​of the power allocation information of the two beams (the power allocation information is multiplied by the signal to achieve the effect of power control) are p0=0.1 and p1=0.2, respectively. The transmitter has two antennas, and the ideal values ​​of the beam weights of the two beams are [1,1] and [-1,1], respectively. In this scenario, the ideal values ​​of the ideal transmission signals of the two antennas are z0=p0*x0+p1*x1=0.26 and z1=-p0*x0+p1*x1=0.1, respectively. Considering the fixed-point quantization of the baseband signal, assuming 8-bit quantization (256 quantization levels) and quantization step size d=1 / 256, the quantization results of x0 and x1 are X0=round(x0*256)=205 and X1=round(x1*256)=230 respectively.

[0067] It should be noted that, in order to simplify the calculation process, the quantization errors of the power allocation information and the beam weights are not considered during the subsequent quantization error calculation. Even if they are not considered, it does not affect the final comparison of the quantization errors.

[0068] (1) The quantization error of the baseband module when it sends the px obtained by multiplying the baseband signal by the power allocation information to the antenna module:

[0069] First, the baseband module calculates the baseband signals after power control of the two beams and uses 8-bit quantization Y0=round(x0*256*p0)=20, Y1=round(x1*256*p1)=46. Then the antenna module calculates the transmitted signals of the two antennas Z0=round(Y0+Y1)=66, Z1= round(-Y0+Y1)=26. The quantization errors are e0=abs(Z0 / 256-z0) / z0=0.0084, e1=abs(Z1 / 256-z1) / z0=0.0156 respectively.

[0070] (2) The baseband module sends the baseband signals X0 and X1 and the power allocation information p0 and p1 to the antenna module, and the quantization error processed by the antenna module is:

[0071] The antenna module calculates the transmitted signals of the two antennas as Z0=round(X0*p0+X1*p1)=67 and Z1= round(-X0*p0+X1*p1)=26. The quantization errors are e0=abs( Z0 / 256-z0) / z0=0.0066 and e1= abs( Z1 / 256-z1) / z0=0.0156 respectively.

[0072] It can be seen that the quantization error of method (2) is smaller than that of method (1).

[0073] In some embodiments, the antenna module may include one or more RRUs and antenna units. The RRU may be referred to as a transceiver unit, a transceiver, a transceiver circuit, or a transceiver, etc., which may include a radio frequency unit, which is mainly used for receiving and transmitting radio frequency signals and converting radio frequency signals into baseband signals, such as for sending signaling information to a receiving device, etc. The antenna unit is mainly used for weighted processing of signals and mapping the processed signals to different beams for transmission.

[0074] It should be understood that the baseband module and the antenna module may be physically arranged together or physically isolated, such as a distributed base station, and this application is not limited to this.

[0075] In the above implementation process, the service needs of different users can be reflected by allocating power to each beam. The baseband module obtains the power allocation information of each beam, and the power allocation information can be used to achieve differentiated allocation of the transmission power of each beam. Therefore, compared with the average power allocation method on the antenna module side, this solution can provide a more refined power control strategy to optimize signal transmission and improve the overall performance of the system. In addition, in the solution of this application, the baseband module separates the baseband signal and the power allocation information and transmits them to the antenna module, so that the quantization error can be effectively reduced under the premise of a fixed number of quantization bits.

[0076] Based on the above embodiment, when sending power allocation information, the baseband module can carry the power allocation information through the reserved field in the communication protocol between the baseband module and the antenna module, and send it to the antenna module. Of course, the baseband signal can be sent according to the relevant provisions in the communication protocol.

[0077] The communication protocol between the baseband module and the antenna module depends on the specific system design and the implementation of the manufacturer. For example, the baseband module and the antenna module may use the Ethernet protocol, or some interface protocols, dedicated communication protocols, etc.

[0078] Generally, a reserved field is set in the communication protocol. The reserved field is generally used for extension or special purpose, which can be understood as a field that has not been used in the current protocol. Therefore, in this solution, the power allocation information can be sent by carrying the reserved field.

[0079] Before sending the power allocation information through the reserved field, you can first determine one of the reserved fields in the communication protocol, for example, you can select any reserved field, and then define the purpose and size of the reserved field, and then put the power allocation information into the reserved field, and build a complete data frame according to the requirements of the communication protocol, including the frame header, payload and frame tail, etc., and then encapsulate the constructed data frame through the corresponding interface and send it to the antenna module.

[0080] It can be understood that the baseband signal and the power allocation information can be sent separately, so that the power allocation information and the baseband signal can be separated in the baseband module. In this way, under the premise that the signal quantization step is fixed, the reduction in the transmission power of the transmission signal of a certain beam will not cause the quantization error of the transmission signal to increase.

[0081] In the above implementation process, the power allocation information is sent through the reserved field in the communication protocol, which does not occupy additional transmission fields, saves transmission resources, and does not require modification of the original protocol.

[0082] On the basis of the above embodiment, when acquiring the power allocation information of each beam, the baseband module may first determine the target transmit power of each beam, and then determine the power allocation information of each beam according to the target transmit power of each beam.

[0083] The target transmit power of each beam can be determined based on relevant information, such as channel state information. For example, the receiving device measures the channel state information, including signal strength, signal-to-noise ratio, phase, delay, etc., during the process of receiving the signal, and then feeds the state information back to the transmitting device. The transmitting device can determine the target transmit power of each beam based on this information. For example, the baseband module can determine the target transmit power based on the bit error rate, signal interference noise, signal quality, etc.

[0084] In some implementations, for example, the baseband module may determine the target transmit power of each beam according to the status information and user requirements, for example, a water injection algorithm may be used to allocate appropriate power to each beam, thereby obtaining the target transmit power of each beam.

[0085] After determining the target transmit power of each beam, the power allocation information may be determined according to the current transmit power of each beam. The power allocation information may be referred to as a power control factor, which may be equal to the ratio of the target transmit power to the total transmit power (i.e., the total power of multiple beams), i.e., the product of the power control factor and the total transmit power is equal to the target transmit power.

[0086] In the above implementation process, the power allocation information of each beam can be determined differentially according to the target transmission power of each beam, so as to realize differentiated power allocation, optimize the power allocation strategy, and improve system performance.

[0087] Based on the above embodiment, the baseband module can also generate beam control information for each beam, the beam control information includes the beam direction, and then send the beam control information to the antenna module. The antenna module is used to determine the beam weight of each beam according to the beam control information, and the beam weight is used for weighted processing.

[0088] Among them, beam control information is key information for beamforming and directional transmission, and can be used to guide the antenna module on how to adjust the transmission direction of each beam. When generating beam control information, the baseband module can collect channel state information and calculate the optimal direction of each beam to maximize signal gain and minimize interference, thereby obtaining beam control information.

[0089] The beam direction may include information such as the angle, azimuth, and elevation of the beam, or a vector direction relative to a reference point.

[0090] The antenna module calculates beam weights in a way that, based on the geometric layout of the antenna array (e.g., Uniform Linear Array (ULA) or Uniform Rectangular Array (URA)), determines an array response vector that describes the array's response to incident waves from a specific direction. For each antenna element, the phase offset due to the beam direction can be calculated. Beam weights can then be calculated based on the array response vector and beam control information, which can be used to adjust the signal phase and amplitude of each antenna element to form a beam pointing in a specific direction.

[0091] Taking the uniform linear array (ULA) as an example, assume a uniform linear array with L antenna elements, the distance between array elements is d, and the signal arrival angle is (beam direction), then the array response vector It can be expressed as follows:

[0092] ;

[0093] in, represents the wavelength of the signal, Represents the imaginary part.

[0094] Using the array response vector above, a beamforming algorithm can be applied to calculate the beam weight w as follows:

[0095] ;in, represents the corresponding beamforming algorithm.

[0096] In specific applications, there are many beamforming algorithms, such as minimum variance distortion-free response, linear constrained minimum variance, linear phase response, adaptive algorithm, etc.

[0097] The following is an explanation using a specific example.

[0098] If the number of transmit beams is K, i represents the beam index.

[0099] The baseband module generates baseband signals for different beams , i=0,1,...,K-1, quantize using a set number of bits;

[0100] The baseband module determines the power allocation information of different beams based on the target transmit power of different beams. , i=0,1,...,K-1, quantize using a set number of bits;

[0101] The baseband module generates beam control information for different beams , i=0,1,...,K-1, quantize using a set number of bits, including information such as beam direction;

[0102] The baseband module will Send to antenna module;

[0103] Antenna module according to Generate beam weights for the i-th beam ,in is an L-dimensional vector, where L represents the number of transmitting antennas. Each element in corresponds to one antenna;

[0104] The antenna module calculates the transmitted signal ;

[0105] The antenna module sends the L elements in S to L corresponding antennas respectively to complete signal transmission.

[0106] In some other embodiments, the calculation of the above-mentioned beam weights can also be completed in the baseband module, that is, after the baseband module calculates the beam weights, it sends the baseband signal, beam weights and power allocation information to the antenna module, and the antenna module forms a transmission signal through weighted processing.

[0107] In the above implementation process, the beam control information is sent to the antenna module, so that the antenna module can determine the beam weight of each beam, and then the antenna module can quickly realize the power control and signal transmission of each beam.

[0108] Based on the same invention concept, please refer to Figure 3 , Figure 3 A flowchart of another signal processing method provided in an embodiment of the present application, the method is applied to an antenna module of a transmitting device, comprising the following steps:

[0109] Step S210: receiving baseband signals corresponding to each beam and power allocation information of each beam sent by a baseband module of a transmitting device, wherein the power allocation information is used to adjust the transmission power of each beam, and the baseband signals and the power allocation information are quantized using corresponding set bit numbers.

[0110] Step S220: performing weighted processing on the baseband signal based on the power allocation information to form a transmission signal.
