[0002] In wireless communication scenarios (such as industrial IoT, vehicle-to-everything (V2X), and panoramic surround view), low-cost, low-power lightweight base stations are typically required. Traditional 5G small base stations mainly use dedicated base station chips (such as Intel FlexRAN and Qualcomm FSM) or field-programmable gate arrays (FPGAs) to implement complete base station functions. However, base station chips are complex in design, expensive, consume a lot of power, and have redundant functions, making them unsuitable for power-sensitive edge devices. Furthermore, their hardware is fixed, making it difficult to flexibly adapt to specific, non-standard communication needs through software updates. In contrast, user equipment (UE) chips are mass-produced, cost-optimized, low-power, and simple in function, but they are designed as terminal-side chips that only support UE functions. How to utilize lower-cost, simple, and flexible UE chips to achieve lightweight base station functions is an urgent problem to be solved. Summary of the Invention

However, it does not mean that the applicant has used or necessarily used the relevant content of the solution.

[0032] Figure 1 This is a schematic diagram of the structure of a user equipment chip provided in an embodiment of this application. Figure 1 As shown, the UE chip 10 is used as a base station; the UE chip 10 includes a baseband processing module 11 and a data processing module 12, which are connected via a high-speed internal bus. The data processing module 12 can run software radio programs and is responsible for generating downlink control channel information or processing uplink control channel information, etc.

[0033] The baseband processing module 11 includes physical layer processing units such as a data inverse transformation module 111, a data transformation module 112, a PUSCH transmission chain 113, and a PDSCH receiving chain 114. The data processing module 12 is connected to both the data inverse transformation module 111 and the data transformation module 112. The inverse transformation module 111 is connected to the PUSCH transmission chain 113. The data transformation module 112 is connected to the PDSCH receiving chain 114. The data inverse transformation module 111 is used to obtain the data to be transmitted from the data source and convert the data to be transmitted from the frequency domain to the time domain. The process of converting from the frequency domain to the time domain can be the process of inverse fast fourier transform (IFFT). The data transformation module 112 is used to convert the received data from the time domain to the frequency domain and transmit it to the data processing module 12 for processing. The process of converting from the time domain to the frequency domain can be the process of fast fourier transform (FFT).

[0034] In this embodiment, when transmitting user data, the data inverse transformation module 111 uses the PUSCH transmission chain 113 as its data source. The PUSCH transmission chain 113 is remapped to the PDSCH transmission channel for transmitting user data. When transmitting control channel data, the data inverse transformation module 111 uses the data processing module 12 as its data source. When receiving user data, the PDSCH receiving chain is remapped to the PUSCH receiving channel for receiving user data.

[0035] Figure 2 This is a schematic diagram illustrating the principle of a user equipment chip used as a base station, as provided in an embodiment of this application. Figure 2 As shown, the baseband processing module 11 can also be connected to the digital front end 20, the RF module 30, and the antenna 40 to complete signal transmission and reception. The digital front end (DFE) is the digital processing component responsible for receiving and transmitting signals.

[0036] Optionally, for the UE chip 10, non-essential functions such as mobility management and security encryption can be removed according to actual needs, and only the protocol stack part required in the actual application scenario can be retained.

[0037] Optionally, the data processing module 12 can be a digital signal processor integrated into the UE chip, or other processors such as an Advanced Reduced Instruction Set Computing (RISC) machine (ARM) or a microprocessor without interlocked pipelined stages (MIPS). The data processing module enables control channel processing and innovative data flow scheduling mechanisms, thereby achieving complete lightweight base station functionality without altering the UE chip hardware design.

[0038] This application provides a hardware and software co-engineering architecture based on a UE chip. By remapping the original transmit and receive chains in the UE chip and combining data transformation or inverse transformation modules and data processing modules, the transmission and processing of uplink and downlink data are realized, thereby utilizing the UE chip to achieve a low-cost, low-power, lightweight base station function.

[0039] In one embodiment, for transmitting control channel data, the data processing module 12 is specifically used to generate frequency domain data of the downlink synchronization and broadcast channel and / or frequency domain data of the Physical Downlink Control Channel (PDCCH), and transmit them to the data inverse transformation module 111. The downlink synchronization and broadcast channel includes the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), and the Physical Broadcast Channel (PBCH), etc. The data processing module 12 can generate the frequency domain data (also called baseband data) of the downlink synchronization and broadcast channel through software radio, thereby realizing the function of the base station transmitting downlink control channel data.

[0040] In one embodiment, when receiving control channel data, the data processing module 12 is further configured to receive and decode data on the Physical Uplink Control Channel (PUCCH) and / or the Physical Random Access Channel (PRACH), thereby enabling the base station to receive uplink control channel data and perform random access functions.

[0041] In one embodiment, such as Figure 2As shown, the baseband processing module 11 also includes a control unit 115 and a data selector 116 (also called a multiplexer (MUX)). The control unit 115 controls the data selector 116 according to the current situation to switch the data source of the data inverse conversion module 111. The control unit 115 may be a control register, used via an Advanced eXtensible Interface (AXI) bus to control the dual data source switching state of the data inverse conversion module 111, thereby coordinating the data flow between the data processing module 12 and the baseband processing module 11.

[0042] For example, when sending user data, the control unit 115 sets the data selector 116 to mode 1, indicating that the data source of the data inverse conversion module 111 is the PUSCH transmission chain 113 (default baseband data source), and the data is processed by the native PUSCH transmission chain 113 of the baseband processing module 11; when sending control channel data, the control unit 115 sets the data selector 116 to mode 2 (DSP injection source), indicating that the data source of the data inverse conversion module 111 is the data processing module 12, and the baseband data is generated by the data processing module 12 and transmitted to the data inverse conversion module 111 through the internal bus.

[0043] Figure 3 This is a flowchart illustrating a data processing method provided in an embodiment of this application. This embodiment is applicable to situations where a UE chip is used to implement base station functions. Specifically, this data processing method can be implemented based on a UE chip as described in any of the above embodiments. This UE chip can be implemented through software and / or hardware and integrated into the communication system. Figure 3 As shown, this data processing method specifically includes the following steps:

[0044] S100 and UE chips are powered on.

[0045] S110. In the case of sending user data, the data inverse transformation module obtains the user data to be sent from the PUSCH transmission chain and converts the user data to be sent from the frequency domain to the time domain.

[0046] S120. In the case of transmitting control channel data, the data inverse transformation module obtains the control channel data to be transmitted from the data processing module and converts the control channel data to be transmitted from the frequency domain to the time domain.

[0047] S130. When receiving user data, the data transformation module converts the received user data from the time domain to the frequency domain and transmits it to the data processing module for processing.

[0048] It should be noted that technical details not described in detail in this embodiment can be found in any of the above embodiments.

[0049] The data processing method in this embodiment achieves lightweight base station functionality on the UE chip through an innovative hardware and software co-architecture and protocol stack reconstruction method, significantly reducing cost, power consumption and complexity, while maintaining the high-performance characteristics of NewRadin (NR).

[0050] In one embodiment, the method further includes:

[0051] S140. In the case of transmitting control channel data, the data processing module generates frequency domain data of downlink synchronization and broadcast channels and / or frequency domain data of PDCCH.

[0052] In one embodiment, the method further includes:

[0053] S150. In the case of receiving control channel data, the data processing module performs data reception and data decoding on PUCCH and / or PRACH.

[0054] In one embodiment, the method further includes:

[0055] S160. The control unit controls the data selector according to the current situation to switch the data source of the data inverse transformation module.

[0056] The data processing method provided in this application can be implemented based on the user equipment chip provided in any of the above embodiments, and has corresponding functions and beneficial effects.

[0057] Figure 4 This is a schematic diagram illustrating a data source switching method provided in an embodiment of this application. Figure 4 As shown, during the data source switching process, a dynamic resource allocation strategy can be adopted to ensure the transmission latency and reliability of the control channel and data channel.

[0058] During the initialization phase: When the system is powered on, the control module configures the data source of the inverse data transformation module (IFFT module) to mode 1 (default baseband data source).

[0059] For downlink control channel data: The data processing module (the DSP built into the UE chip) generates baseband frequency domain data for downlink synchronization and broadcast channels (PSS / SSS / PBCH) and frequency domain data for PDCCH in real time via software radio according to the base station protocol requirements.

[0060] The control module switches the data source of the IFFT module to mode 2 (DSP injection source); the frequency domain data generated by the DSP is injected into the IFFT module of the UE chip through a high-speed interface; the IFFT module converts the injected frequency domain data into a time domain signal, which is then transmitted through the DFE and RF modules.

[0061] For downlink non-control channel (PDSCH) data: when transmitting user data, the control module switches the data source back to mode 1; the upper layer data of the base station protocol stack is processed through the native PUSCH transmission chain to generate PDSCH baseband data, which is then transmitted via IFFT, DFE, and RF.

[0062] For uplink reception, the PUSCH signal sent by the user is processed by the native PDSCH receiver chain after passing through RF, DFE, and FFT to achieve data reception; if it is PRACH or PUCCH, it is processed by the PRACH / PUCCH receiver module of the DSP after passing through RF, DFE, and FFT.

[0063] The base station function of the UE chip is illustrated below through a specific embodiment.

[0064] Taking the wireless 360° surround view system as an example, the hardware configuration includes: using a 5G UE chip, integrating a multi-core open instruction set architecture (Reduced Instruction Set Computer Five, RISC-V) DSP processor and a 5G NR baseband processing module.

[0065] The software deployment includes: running control channel processing software on the DSP to generate PSS / SSS / PBCH / PDCCH and receive PRACH / PUCCH. A trimmed base station protocol stack runs on the baseband processing module, including control layers such as Non-Access Stratum (NAS), Radio Resource Control (RRC), PDCP, Medium Access Control (MAC), and Physical Layer (PHY). NAS is a locally trimmed core network software.

[0066] The work process is as follows:

[0067] After the base station (UE chip) is started, the control module sets the MUX to mode 2 based on the control logic. The DSP generates and injects frequency domain data into the SSB (PSS / SSS / PBCH), which is then converted into a time domain signal by the IFFT module and broadcast.

[0068] The terminal (UE) searches for a cell and initiates random access;

[0069] The base station DSP receives the PRACH and generates the PDCCH or Downlink Control Information (DCI) of the Random Access Response (RAR), which is then injected and sent again via Mode 2.

[0070] After successful terminal access, the data transmission phase begins. When it is necessary to send video stream control signaling or user data (PDSCH) to the terminal, the control module switches the MUX back to mode 1, and the data is processed and sent through the chip's native PUSCH transmission chain.

[0071] When the terminal uploads video data (PUSCH), the signal is received by the base station antenna, and after RF and FFT transformation, it is processed and decoded by the chip's native PDSCH receiver chain.

[0072] When the terminal sends a PUCCH, the signal is received by the base station antenna, and after RF and FFT transformation, it is processed and decoded by the PUCCH receiving software of the DSP.

[0073] Actual tests show that this method successfully achieved a stable connection with four cameras, achieving a downlink transmission rate of 1.2Gbps and an end-to-end latency of less than 50ms, fully meeting the requirements for wireless 360° surround view.

[0074] The method in this application utilizes mass-produced, low-cost UE chips and an innovative hardware-software co-engineering architecture to significantly reduce hardware costs (by more than 95%) and power consumption (by more than 90%). Through protocol stack function remapping and trimming, it eliminates unnecessary functional redundancy for dedicated scenarios while maintaining high-performance wireless communication, simplifying system design. Control channel processing is implemented through DSP software radio, providing great flexibility and enabling rapid adaptation to different protocol variants and customized requirements. The hardware function remapping method creatively redefines the terminal-side hardware modules of the UE chip as base station-side functions, breaking the original limitations of the chip design. The data channel is still processed by the hardware acceleration module, ensuring the throughput and real-time performance of high-speed data services. A dual-data source injection mechanism is adopted, introducing a dual-data source selection switch (mode 1 / mode 2) before the IFFT module. Control channel data generated by the software is injected in real-time by the DSP, compensating for the UE chip's inability to natively generate the base station downlink channel. The heterogeneous architecture of "DSP (software-generated downlink control channel + PRACH / PUCCH reception) + modified UE chip (hardware-processed data channel)" achieves extreme flexibility and cost optimization while ensuring performance.
