Detailed Implementation

[0014] This invention provides a PDCCH space division multiplexing method, apparatus, and device.

[0015] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0016] like Figure 1 As shown, this embodiment of the invention provides a PDCCH spatial multiplexing method, the execution subject of which can be a base station. The method specifically includes the following steps: In step S102, the transmit power threshold of the terminal device within the PDCCH scheduling period is determined based on the peer signal power and line-of-sight probability of the terminal device within the beam coverage area of ​​the base station.

[0017] The terminal device can be any device within the beam coverage area. For example, the terminal device can be a drone terminal flying at a preset altitude range.

[0018] In implementation, the server can use a pre-trained threshold determination model to determine the transmit power threshold of the terminal device within the PDCCH scheduling period based on the peer signal power and line-of-sight (LoS) path probability of the terminal device within the beam coverage area of ​​the base station. The threshold determination model can be a model built based on a preset deep learning algorithm.

[0019] Alternatively, the base station's server can determine the terminal device's transmit power threshold within the PDCCH scheduling cycle based on a preset correspondence between the peer signal power, line-of-sight probability, and transmit power threshold.

[0020] Furthermore, the method for determining the transmit power threshold of the terminal device within the PDCCH scheduling period is an optional and implementable method. In actual application scenarios, there can be a variety of different methods. Different methods can be selected according to different actual application scenarios. This specification does not specifically limit this method in the embodiments.

[0021] In step S104, within the PDCCH scheduling period, the mapping relationship between control channel elements and analog beams is determined based on the location information, pitch angle, and line-of-sight probability of the terminal device.

[0022] In implementation, the server can use a pre-trained relation determination model to determine the mapping relationship between control channel elements and simulated beams based on the location information, pitch angle, and line-of-sight probability of the terminal device. The relation determination model can be a model built based on a preset deep learning algorithm.

[0023] In step S106, the beamforming weights corresponding to the terminal devices are optimized based on the mapping relationship to obtain the optimized beamforming weights.

[0024] In implementation, the server can obtain the beamforming weights corresponding to the terminal device, and then optimize the beamforming weights corresponding to the terminal device based on the obtained mapping relationship using a pre-trained optimization model to obtain the optimized beamforming weights. The optimization model can be a model built based on a preset deep learning algorithm.

[0025] In step S108, the scheduling instruction is sent to the terminal device.

[0026] The scheduling instruction may include a transmit power threshold and an optimized beamforming weight. The scheduling instruction can be used to trigger the terminal device to determine the receive beam based on the optimized pitch angle beamforming weight and adjust the transmit power based on the transmit power threshold.

[0027] In implementation, the base station can send the scheduling command corresponding to each terminal device to the corresponding terminal device to trigger the terminal device to determine the transmission power of the terminal device based on the transmission power threshold, and determine the receiving beam based on the optimized pitch angle beamforming weight, so as to demodulate the PDCCH information from the receiving beam, complete the resource activation process, and enable PDCCH spatial multiplexing.

[0028] For scenarios involving intensive drone scheduling, such as low-altitude logistics delivery and low-altitude inspection, this technology can effectively alleviate the problem of limited control channel resources and improve the system's parallel scheduling capabilities. At the same time, through analog beam technology, it can significantly reduce the hardware complexity and deployment cost on the base station side, demonstrating significant engineering feasibility and promotional value.

[0029] This invention provides a PDCCH spatial division multiplexing method. Based on the peer signal power and line-of-sight probability of terminal devices within the beam coverage area of ​​a base station, the transmit power threshold of the terminal device during the PDCCH scheduling period is determined. The terminal device can be any device within the beam coverage area. During the PDCCH scheduling period, based on the location information, elevation angle, and line-of-sight probability of the terminal device, the mapping relationship between control channel elements and analog beams is determined. Based on the mapping relationship, the beamforming weights corresponding to the terminal device are optimized to obtain optimized beamforming weights. Scheduling instructions are then sent to the terminal device. Thus, by introducing the line-of-sight probability, control capacity can be maximized, improving the efficiency of high-reliability link resource reuse and overcoming the bottleneck of limited capacity utilization. Furthermore, by dynamically adjusting the transmit power in conjunction with spatial isolation and Loss of Sense Time (LoS) characteristics, low-altitude direct interference leakage can be suppressed, enhancing the stability of PDCCH signaling transmission. Additionally, through the optimization mechanism of the mapping relationship and beamforming weights, the parallel capability of multiple terminals in low-altitude dense scheduling scenarios can be improved, increasing the PDCCH spatial division utilization rate.

[0030] In practical applications, beamforming weights can also be determined based on the location information and pitch angle of the terminal device. There are various methods for determining beamforming weights; the following provides one optional processing method, such as... Figure 2 As shown, the specific process may include the following steps S202 to S206.

[0031] In step S202, the location information of the terminal device in the coordinates of the base station and the elevation angle of the terminal device relative to the base station are received.

[0032] In step S204, the pitch angle interval is divided into multiple pitch angle sub-intervals based on the pitch angle.

[0033] In implementation, taking the UAV terminal as an example, let's assume the three-dimensional position vector of the UAV terminal u in the base station coordinate system. for: , in, Indicates the flight altitude in low-altitude operational scenarios. Let x be the x-coordinate of the drone terminal. The vertical coordinate is the coordinate of the UAV terminal.

[0034] The pitch angle of the drone terminal relative to the base station It can be: .

[0035] Then, the pitch angle can be adjusted. Quantization mapping to discrete beam tags Based on the air-to-ground propagation model (A2G) defined in 3GPP, the probability of the Loss of Sight (LoS) path in the link is calculated as follows: :

[0036] in, These are the parameters for model fitting.

[0037] After completing the spatial location and link characteristics modeling of the terminal equipment, a simulated beam set adapted to low-altitude scenarios can be constructed based on the pitch angle and line-of-sight characteristics of the terminal equipment to improve the separation and reuse efficiency of control surface airspace resources.

[0038] Specifically, it can be based on the pitch angle label of the terminal device u. The overall pitch angle range [0 90 The beam is divided into B discrete sectors (i.e., multiple elevation sub-sectors), with each beam b covering the corresponding elevation sub-sector. :

[0039] In step S206, the beamforming weights of the beams corresponding to the pitch sub-intervals are determined based on the downlink channel vectors of the terminal devices within the pitch sub-intervals.

[0040] In implementation, a set of simulated beamforming weight vectors w can be pre-configured for each beam b. b (i.e., beamforming weights) to achieve beam alignment and spatial isolation of terminal equipment within the pitch angle region. Beam weight vector w b The design goal is to maximize main lobe gain and suppress side lobe leakage.

[0041] in, This is the conjugate transpose of the downlink channel vector of terminal device u. The beamb shaping weight coefficient vector is used to form a simulated beam set covering the entire low-altitude region through pitch angle quantization and spatial beam discretization. This ensures the isolation between adjacent beams meets the corresponding threshold, providing spatial foundation support for subsequent dynamic mapping and optimized scheduling of PDCCH resources based on spatial domain separation.

[0042] In step S102 above, the specific processing method for determining the transmit power threshold of the terminal device within the PDCCH scheduling period based on the peer signal power and line-of-sight probability of the terminal device within the beam coverage area of ​​the base station can vary. One optional processing method is provided below, such as... Figure 3 As shown, the specific process may include the following steps S1022 to S1028.

[0043] In step S1022, the ratio between the peer signal power of the terminal device and the total interference power is obtained.

[0044] In step S1024, the mean probability of the line-of-sight path probability of the terminal device within the coverage area of ​​the beam corresponding to the pitch sub-interval to which the terminal device belongs is obtained.

[0045] In step S1026, it is determined whether the terminal device is mapped to the pitch sub-interval to which the terminal device belongs, and the first determination result is obtained.

[0046] In step S1028, the transmit power threshold of the terminal device within the PDCCH scheduling period is determined based on the first judgment result, the ratio, and the probability mean.

[0047] In implementation, in dense spatial division scenarios, inter-beam interference becomes the main factor affecting the reliability of PDCCH. Therefore, based on maximizing capacity, power control and interference constraints incorporating link Loss statistics can be added. The following interference suppression algorithm can ensure that inter-channel interference remains within a controllable range during spatial multiplexing: , in, It can be used to characterize whether terminal device U is mapped to the pitch sub-interval to which the terminal device belongs. It can be used to characterize the transmit power threshold of terminal device U during the PDCCH scheduling period. It can be used to characterize the ratio between the peer signal power and the total interference power of the terminal device. This is the mean probability of the line-of-sight path probability of the terminal device within the coverage area of ​​the beam corresponding to the pitch sub-interval to which the terminal device belongs.

[0048] In this way, the transmit power can be dynamically constrained based on two main factors: spatial isolation and LOS path probability, thereby achieving interference suppression. When the spatial isolation of the two terminals... When the performance is poor, the total transmit power can be reduced accordingly to avoid severe inter-beam interference. On the other hand, when the probability of Loss of Signal (LoS) is high within the beam coverage area... When this is done, the power budget can be dynamically tightened to limit strong interference leakage under direct air path and improve the overall interference tolerance of the system. This constraint design ensures that while the spatial multiplexing capability is improved, the system interference level remains within an acceptable range, guaranteeing reliable transmission of PDCCH signaling.

[0049] In step S104 above, the specific processing method for determining the mapping relationship between control channel elements and analog beams based on the terminal device's location information, pitch angle, and line-of-sight probability can vary. One optional processing method is provided below, such as... Figure 4 As shown, the specific process may include the following steps S1042 to S1048.

[0050] In step S1042, the pitch angle sub-region to which the terminal device belongs is determined based on the location information of the terminal device.

[0051] In step S1044, a first loss value is determined based on the pitch angle of the terminal device and the pitch angle of the beam corresponding to the pitch angle sub-region to which the terminal device belongs.

[0052] In step S1046, the mapping relationship between the control channel elements and the analog beam is determined based on the line-of-sight probability of the terminal device, the signal-to-noise ratio of the control signal received under the spatial interference environment, the first loss value, and the beamforming weight corresponding to the terminal device.

[0053] In implementation, during each PDCCH scheduling cycle, the base station can redetermine the mapping relationship from CCE to analog beam based on the location information, elevation angle, and Loss of Sight (LoS) probability of all terminal devices, maximizing capacity and improving elevation angle matching according to the following formula:

[0054] Among them, the first item The desired capacity function can be used to represent the beamforming weights given a specific beamforming weight. Under the mapping relationship Π, the sum of the expected control capacities can be used to encourage improved spatial reuse capabilities of the system. (Second term) The pitch angle and beam index matching penalty term (i.e., the first loss value and trade-off coefficient) can be used to constrain terminal equipment to prioritize beams with high pitch angle matching to reduce interference and capacity loss caused by beam mismatch. λ is the trade-off coefficient, thereby improving PDCCH reception success rate and spatial separation.

[0055] While ensuring reliable PDCCH demodulation, the number of terminals scheduled in parallel can be increased. Since PDCCH is limited by control resource sets and spatial interference, the key to improving capacity lies in optimizing the spatial multiplexing efficiency of the control channel. Considering the generally high Loss-of-Sight (LoS) path probability of low-altitude links, LoS weighting can be introduced to fully utilize spatial reusability, thereby increasing the priority of control resource allocation for high-reliability links and optimizing spatial multiplexing efficiency. The objective function can be defined as follows: , in, It can be used to represent a beamforming weight matrix that includes beamforming weights. It can be used to represent the mapping relationship between control channel elements (CCEs) and analog beams. It can be used to represent the signal-to-noise ratio of control signals received by terminal equipment under U-shaped spatial interference environment.

[0056] In the above model, This directly impacts the importance of each terminal device's contribution to the total system capacity. By adding weighting coefficients, users with good line-of-sight and good spatial isolation can be prioritized during spatial multiplexing, thereby maximizing the overall resource utilization of the system. Furthermore, the capacity model can incorporate... The function can reflect the decreasing probability of reliable demodulation of control information as SINR increases.

[0057] like Figure 5 As shown, once the mapping relationship between CCE and beam is determined, the system can further optimize and adjust the beam weights and user transmit power under a fixed mapping based on the following formula, thereby improving the fine-grained spatial division capability: .

[0058] loss function By comprehensively considering factors such as inter-beam interference leakage and control signaling reception reliability, and through alternating iterative optimization of outer-layer resource mapping and inner-layer beam weight fine-tuning, spatial scheduling and power configuration can be rapidly converged, achieving the dual objectives of improving control capacity and suppressing interference.

[0059] Ultimately, the terminal device can select the receiving beam that best matches its own elevation angle based on the pre-configured beam direction information, demodulate the PDCCH information from the corresponding beam, complete the resource activation process, and enable PDCCH spatial multiplexing.

[0060] In this way, the base station KY calculates the pitch angle of the terminal device based on the real-time 3D position information reported by the UAV terminal, and estimates the Loss of Position (LoS) probability by combining the horizontal position and altitude information. By introducing pitch angle quantization and LoS probability weighting mechanisms, the base station generates multiple spatially isolated simulated beams and groups users according to the spatial distribution characteristics of the terminal devices, achieving efficient spatial reuse of PDCCH control information within the same control resource set. During the resource scheduling phase, a dynamic transmit power budget mechanism based on link LoS probability can prioritize the spatial scheduling opportunities of line-of-sight links and tighten the transmit power limit for high-LoS link beams to suppress direct interference leakage. Subsequently, based on the outer CCE to beam direction mapping, an inner beam weight and transmit power fine-tuning mechanism is further introduced, combining interference leakage constraints and local power budget to optimize the spatial isolation between beams and signaling reliability. Finally, the terminal device can complete the matching reception and decoding of PDCCH control information according to the pre-configured beam reception direction and real-time channel feedback.

[0061] Among them, the low-altitude scene and user feature characterization method in the above process can establish an airspace characteristic modeling system based on the three-dimensional position information, pitch angle calculation and line-of-sight (LoS) probability estimation reported by the terminal device in real time, generate simulated beams, provide a basis for subsequent wave resource allocation and other processes, and improve the accuracy of airspace resource adaptation.

[0062] The line-of-sight weighted capacity maximization method can construct a control capacity maximization objective function by introducing a Loss probability weighting mechanism, prioritizing the allocation of control channel resources for high line-of-sight links, and alleviating the pressure of large-scale concurrent scheduling in low-altitude areas.

[0063] The dynamic power constraint method based on interference intensity can dynamically adjust the beam transmit power budget by combining the spatial isolation between terminal devices and the LoS statistical characteristics of the beam coverage area, thereby suppressing air interference leakage caused by low-altitude direct links and suppressing low-altitude interference leakage.

[0064] The dynamic resource mapping method can be used to fine-tune beamforming weights and transmit power for fixed mapping relationships through a dynamic resource mapping mechanism from CCE to beam direction, thereby achieving two-layer collaborative optimization and improving the overall spatial multiplexing performance.

[0065] This invention provides a PDCCH spatial division multiplexing method. Based on the peer signal power and line-of-sight probability of terminal devices within the beam coverage area of ​​a base station, the transmit power threshold of the terminal device during the PDCCH scheduling period is determined. The terminal device can be any device within the beam coverage area. During the PDCCH scheduling period, based on the location information, elevation angle, and line-of-sight probability of the terminal device, the mapping relationship between control channel elements and analog beams is determined. Based on the mapping relationship, the beamforming weights corresponding to the terminal device are optimized to obtain optimized beamforming weights. Scheduling instructions are then sent to the terminal device. Thus, by introducing the line-of-sight probability, control capacity can be maximized, improving the efficiency of high-reliability link resource reuse and overcoming the bottleneck of limited capacity utilization. Furthermore, by dynamically adjusting the transmit power in conjunction with spatial isolation and Loss of Sense Time (LoS) characteristics, low-altitude direct interference leakage can be suppressed, enhancing the stability of PDCCH signaling transmission. Additionally, through the optimization mechanism of the mapping relationship and beamforming weights, the parallel capability of multiple terminals in low-altitude dense scheduling scenarios can be improved, increasing the PDCCH spatial division utilization rate.

[0066] like Figure 6 As shown, this embodiment of the invention provides a PDCCH spatial multiplexing method. The executing entity of this method can be a terminal device, such as a drone. The method specifically includes the following steps: In step S602, the location information and elevation angle of the terminal device are sent to the base station.

[0067] In step S604, a scheduling instruction sent by the base station is received.

[0068] The scheduling instructions may include a transmit power threshold and optimized beamforming weights. The transmit power threshold is determined by the peer signal power and line-of-sight probability of the terminal equipment within the beam coverage area of ​​the base station. The optimized beamforming weights can be obtained by the base station optimizing the beamforming weights corresponding to the terminal equipment based on the mapping relationship between control channel elements and analog beams. The mapping relationship can be determined by the base station based on the location information, pitch angle and line-of-sight probability of the terminal equipment within the PDCCH scheduling period.

[0069] In step S608, the transmit power of the terminal device is determined based on the transmit power threshold, and the receive beam is determined based on the optimized pitch angle beamforming weight.

[0070] This invention provides a PDCCH spatial multiplexing method, which receives a model update request for a business processing model, and in response to the model update request, obtains training data corresponding to the business domain to which the business processing model belongs, trains the business processing model based on the training data, and determines whether the trained business processing model meets the model training requirements. If it is determined that the trained business processing model does not meet the model training requirements, target modal data that meets a preset complementary relationship with the training data is selected from other modal data according to the data dependency relationship between the training data and other modal data. Based on the target modal data and the training data, the trained business processing model is further trained until a business processing model that meets the model training requirements is obtained. The business processing model can be used to process business data related to its business domain. In this way, by introducing line-of-sight probability, control capacity can be maximized, the efficiency of high-reliability link resource reuse can be improved, and the bottleneck of limited capacity utilization can be broken. Furthermore, by dynamically adjusting the transmit power in combination with spatial isolation and LoS characteristics, low-altitude direct interference leakage can be suppressed, and the stability of PDCCH signaling transmission can be enhanced. In addition, through the optimization mechanism of mapping relationship and beamforming weight, the parallel capability of multiple terminals in low-altitude dense scheduling scenarios can be improved, and the spatial utilization rate of PDCCH can be increased.

[0095] The foregoing has described specific embodiments of this specification. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recited in the claims may be performed in a different order than that shown in the embodiments and may still achieve the desired result. Furthermore, the processes depicted in the drawings do not necessarily require the specific or sequential order shown to achieve the desired result. In some embodiments, multitasking and parallel processing are possible or may be advantageous.

[0096] In the 1990s, improvements to a technology could be clearly distinguished as either hardware improvements (e.g., improvements to the circuit structure of diodes, transistors, switches, etc.) or software improvements (improvements to the methodology). However, with technological advancements, many methodological improvements today can be considered direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved methodology into the hardware circuit. Therefore, it cannot be said that a methodological improvement cannot be implemented using hardware physical modules. For example, a Programmable Logic Device (PLD) (such as a Field Programmable Gate Array (FPGA)) is such an integrated circuit whose logic function is determined by the user programming the device. Designers can program and "integrate" a digital system onto a PLD themselves, without needing chip manufacturers to design and manufacture dedicated integrated circuit chips. Furthermore, nowadays, instead of manually manufacturing integrated circuit chips, this programming is mostly implemented using "logic compiler" software. Similar to the software compiler used in program development, the original code before compilation must also be written in a specific programming language, called a Hardware Description Language (HDL). There are many HDLs, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, and RHDL (Ruby Hardware Description Language). Currently, the most commonly used are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also understand that by simply performing some logic programming on the method flow using one of these hardware description languages ​​and programming it into an integrated circuit, the hardware circuit implementing the logical method flow can be easily obtained.

[0097] The controller can be implemented in any suitable manner. For example, it can take the form of a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro)processor, logic gates, switches, application-specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicon Labs C8051F320. A memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also recognize that, in addition to implementing the controller in purely computer-readable program code form, the same functionality can be achieved by logically programming the method steps to make the controller take the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers. Therefore, such a controller can be considered a hardware component, and the means included therein for implementing various functions can also be considered as structures within the hardware component. Alternatively, the means for implementing various functions can be considered as both software modules implementing the method and structures within the hardware component.
