Description

Technical Field

[0001] This application belongs to the field of communication technology, and in particular relates to a communication method, apparatus, device and medium based on uplink sharing. Background Technology

[0002] Uplink (UL) sharing is a time-division multiplexing method used by LTE (Long Term Evolution, 3GPP) and NR (New Radio) communication networks to share the uplink. In practical applications, UL sharing, using LTE-NR dual connectivity (EN-DC) technology, enables coordinated 4G or 5G communication between base stations and terminal devices.

[0003] In related technologies, the BBIC (Baseband Integrated Circuit) is used to process the baseband signals for NR and LTE, while the RFIC (Radio Frequency Circuit) is used to process and transmit the radio frequency signals. Within the BBIC, the NR and LTE communication modules are independent. In the RFIC, analog switches are used to switch between LTE and NR UL services.

[0004] However, switching between LTE and NR UL services via analog switches in the RFIC is time-consuming, requiring hundreds of nanoseconds even with sufficiently high-performance analog switches. While advancing or delaying the handover time can reduce handover latency, it impacts the integrity of the UL service.

[0005] Therefore, it is evident that in the relevant technologies, it is impossible to simultaneously consider the latency of switching time and the integrity of UL services when implementing UL Sharing. Summary of the Invention

[0006] This application provides a communication method, apparatus, device, and medium based on uplink sharing, which can balance the handover time of UL services with the integrity of UL services, thus solving the problem of incompatibility between handover time and UL service integrity in related technologies.

[0007] In a first aspect, embodiments of this application provide a communication method based on uplink sharing, applied to a baseband processing chip (BBIC) of a terminal device. The BBIC is equipped with at least a New Radio (NR) communication module and a Long Term Evolution (LTE) communication module. The method includes: responding to a signal switching command and detecting whether the first signal information of the terminal device in the NR network and the second signal information of the terminal device in the LTE network match; if the first signal information and the second signal information match, determining a target communication module from the NR communication module and the LTE communication module according to service requirement information; switching the real-time transmission signal output by the BBIC to the target transmission signal output by the target communication module, and transmitting the target transmission signal to a radio frequency processing chip (RFIC), so that the RFIC transmits the target transmission signal to the network device through a digital radio frequency front-end.

[0008] Secondly, embodiments of this application provide a communication device based on uplink sharing, applied in the baseband processing chip BBIC of a terminal device. The BBIC is equipped with at least a New Radio (NR) communication module and a Long Term Evolution (LTE) communication module. The device includes: a signal matching module, used to respond to a signal switching command and detect whether the first signal information of the terminal device in the NR network and the second signal information of the terminal device in the LTE network match; a signal determination module, used to determine a target communication module from the NR communication module and the LTE communication module according to service requirement information when the first signal information and the second signal information match; and a signal switching module, used to switch the real-time transmission signal output by the BBIC to the target transmission signal output by the target communication module, and transmit the target transmission signal to the radio frequency processing chip RFIC, so that the RFIC transmits the target transmission signal to the network device through the digital radio frequency front end.

[0009] Thirdly, embodiments of this application provide an electronic device, which includes: a processor and a memory storing computer program instructions; when the processor executes the computer program instructions, it implements the uplink-shared communication method as described in the first aspect.

[0010] Fourthly, embodiments of this application provide a computer-readable storage medium storing computer program instructions, which, when executed by a processor, implement the uplink-shared communication method as described in the first aspect.

[0011] Fifthly, embodiments of this application provide a computer program product in which instructions, when executed by a processor of an electronic device, cause the electronic device to perform the uplink-shared communication method as described in the first aspect.

[0012] As can be seen from the above, in this embodiment, the handover of UL services is implemented on the BBIC side, while the RFIC side uses a single digital radio frequency front-end to process UL services. This advances the handover timing of shared UL services to the BBIC side, thereby shortening the handover time between NR and LTE UL services and reducing the latency of UL service handover. Furthermore, in this embodiment, since the UL service handover is completed on the BBIC side, the handover of UL services avoids impacting the integrity of UL services on the RFIC side, ensuring the integrity of UL services.

[0013] Therefore, the solution provided by the embodiments of this application takes into account both the handover time of UL services and the integrity of UL services, thus solving the problem of incompatibility between handover time and the integrity of UL services in related technologies.

[0028] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0029] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0030] To facilitate understanding, before explaining the solution provided in this application, the background of the solution provided in this application will be explained first.

[0031] 5G(5 th The NSA (Non-Standalone Architecture) mode of NR (5th Generation Mobile Communication Technology) adopts 4G (4G) architecture. thThe 5G network deployment method utilizes the infrastructure of Generation Mobile Communication Technology (4G). Based on the NSA architecture, the 5G carrier only carries user data; its control signaling is still transmitted through the 4G network. This method requires the use of LTE-NR dual connectivity (EN-DC) technology to coordinate 4G or 5G communication between the base station and the terminal device. Furthermore, for areas with insufficient NR UL coverage, EN-DC technology is typically used to implement UL services for terminal devices to improve UL performance; that is, switching NR UL services to LTE for implementation.

[0032] If the terminal device's UL service is configured with one physical antenna, then when using EN-DC technology, LTE / NR need to reuse the radio frequency resources of one physical antenna in a time-division manner, i.e., UL Sharing. If the terminal device's uplink service is configured with two physical antennas, then there are two scenarios when using EN-DC technology. In one scenario, each communication module occupies one physical antenna, in which case UL Sharing is not required; in the other scenario, the LTE communication module's FDD (Frequency Division Duplex) mode uses one physical antenna, and the NR communication module's TDD (Time Division Duplex) mode uses two physical antennas. When NR has UL services, it needs to occupy LTE radio frequency resources, in which case UL resource sharing is also required, i.e., UL Sharing.

[0033] 3GPP(3 rd Section 6.3B.1 of the Generation Partnership Project (3GPP) protocol 381013 describes and specifies the service scenarios for UL Sharing. Based on the switching time capabilities of the output signals of the LTE and NR communication modules reported by the terminal device, two scenarios are defined for the switching of the output signals of the two communication modules (i.e., the switching of UL services). In the first scenario, the switching time is less than 0.5µs; in the second scenario, the switching time is less than 20µs. The protocol also stipulates that the UL timing deviation between LTE and NR must be limited to within 2.21µs. Based on this, we can obtain... Figures 1 to 4 The time templates shown are for different handover time requirements, where, Figure 1 The time template for switching from LTE UL service to NR UL service is shown in the first scenario. Figure 2 The time template for switching from NR UL service to LTE UL service is shown in the first scenario; Figure 3The time template for switching from LTE UL service to NR UL service is shown in the second scenario. Figure 4 This illustrates the time template for switching from NR UL services to LTE UL services in the second scenario. Figures 1 to 4 In this context, LTE timing refers to the time for signal switching of LTE subframes, NR timing refers to the time for signal switching of NR time slots, and shutdown timing refers to the time for stopping signal switching.

[0034] In practical applications, the chips of terminal devices supporting NR / LTE NSA scenarios typically adopt a communication architecture combining BBIC and RFIC, such as... Figure 5 As shown. Figure 5 An architecture diagram of UL service handover in related technologies is shown. Figure 5 It is known that, to save costs, the RFIC side typically uses a single power amplifier, meaning that on the RFIC side, the LTE DFE (Digital Front-End) and the NR DFE share a single PA (Power Amplifier). Figure 5 It is known that in related technologies, UL Sharing is implemented on the RFIC side, that is, the switching between LTE UL services and NR UL services is realized after the DAC (Digital Analog Converter) on the RFIC side.

[0035] like Figure 5 As shown, the baseband processing for NR and LTE is independent in the BBIC; similarly, the radio frequency front-end processing for NR and LTE is also independent in the RFIC. In related technologies, due to the significant differences in bandwidth and scheduling between NR and LTE in non-UL shared mode, UL services for NR and UL services for LTE need to be processed separately. Therefore, in UL shared mode, on the RFIC side, after the DAC of each DFE, a simulated switch is used to achieve the switching of different UL services.

[0036] As described above, in related technologies, the handover of UL services between LTE and NR is implemented on the RFIC side to achieve UL sharing. This method requires a relatively long handover time, even with sufficiently good analog switch performance, it still requires hundreds of nanoseconds. To address the excessive handover latency, related technologies can resolve the issue by advancing the handover time, but this method will affect the integrity of UL services before the handover; alternatively, the handover time can be delayed to address the excessive handover latency, but this method will affect the integrity of UL services after the handover.

[0037] To address the incompatibility between handover latency and UL service integrity, this application provides a communication method, apparatus, device, and medium based on uplink sharing. This method can be applied to... Figure 6 In the BBIC communication architecture shown. Figure 6 In the illustrated communication architecture, the BBIC side deploys an NR communication module, an LTE communication module, a UL service switching switch, and a communication interface with the RFIC. The RFIC side deploys a communication interface with the BBIC, a DFE for NR, a DFE for LTE, a DAC, an analog switch, and a power amplifier (PA). During UL sharing, if the BBIC side detects a discrepancy between the frequency and bandwidth of the terminal device communicating in the NR network and the frequency and bandwidth of the terminal device communicating in the LTE network, a solution from related technologies is used to switch UL services. Specifically, in the RFIC, NR and LTE use independent DFE modules to share the radio frequency channel and physical antenna, and an analog switch is used after the DAC to achieve UL service switching.

[0038] If the frequency and bandwidth of the terminal device communicating in the NR network are detected on the BBIC side to be consistent with the frequency and bandwidth of the terminal device communicating in the LTE network, then a single DFE on the RFIC side will handle the UL service. Leveraging the inherent advantage of the BBIC and RFIC being separate and communicating via an interface, the handover of the UL service will be completed in the digital domain on the BBIC side. In this scenario, unused DFEs and analog switches in the RFIC will cease operation.

[0039] The following section first introduces the communication method based on uplink sharing provided in the embodiments of this application.

[0040] Figure 7 A flowchart illustrating a communication method based on uplink sharing according to an embodiment of this application is shown. Figure 7 As shown, the method includes the following steps:

[0041] Step S701: In response to the signal switching command, detect whether the first signal information of the terminal device in the NR network and the second signal information of the terminal device in the LTE network match.

[0042] In one scenario, when the terminal device is in an area with insufficient NR network coverage, the terminal device uses EN-DC technology to complete the UL service. At this time, the terminal device's communication system generates a signal switching command, and the BBIC can respond to the signal switching command and realize the switching of the UL service.

[0043] In another scenario, when the terminal device is in a 5G network deployed in the NSA networking mode, the terminal device can determine the base station type based on the signal received from the base station. When the base station type is detected as a 4G base station, the terminal device uses EN-DC technology to complete the uplink service of the terminal device. At this time, the communication system of the terminal device generates a signal switching command, and the BBIC can respond to the signal switching command and realize the switching of UL service.

[0044] Another scenario exists where the terminal device uses two physical antennas to implement UL services. Specifically, LTE FDD uses one physical antenna, and NR TDD uses two physical antennas. When the terminal device detects that the NR communication module needs to process UL services, it uses EN-DC technology to complete the uplink service of the terminal device. At this time, the terminal device's communication system generates a signal switching command, and the BBIC can respond to the signal switching command and realize the switching of UL services.

[0045] It should be noted that the terminal devices involved in the above three scenarios are entities on the user side used to receive or transmit signals. These can be mobile phones, tablets, laptops, PDAs, mobile internet devices, wearable devices, etc., as well as terminal devices in IoT systems, and sensors such as smart printers, train detectors, and gas stations.

[0046] In step S701, a processing unit may be deployed in the BBIC. This processing unit can detect whether the signal information required for the terminal device to communicate in the NR network and the LTE network is matched. If they match, the solution provided in the embodiments of this application is used to switch the UL service; if they do not match, the solution provided by related technologies is used to switch the UL service.

[0047] It should be noted that in step S701, the first signal information is used to characterize the signal information required for the terminal device to communicate in the NR network, and the second signal information is used to characterize the signal information required for the terminal device to communicate in the LTE network. The first signal information and the second signal information mentioned above include, but are not limited to, frequency and bandwidth.

[0048] Step S702: If the first signal information matches the second signal information, the target communication module is determined from the NR communication module and the LTE communication module according to the service requirement information.

[0049] It should be noted that in step S702, when two signal information matches, the BBIC determines whether a service handover is needed based on actual service requirements, and whether the UL service after the handover is an NR UL service or an LTE UL service. For example, when the terminal device is in a 5G network, the BBIC uses the NR communication module to achieve communication between the terminal and the base station; when the terminal device moves to an area with insufficient 5G network coverage, the BBIC performs a UL service handover, transmitting the signal output from the LTE communication module to the base station to achieve the UL service handover.

[0050] Step S703: Switch the real-time transmission signal output by BBIC to the target transmission signal output by the target communication module, and transmit the target transmission signal to the radio frequency processing chip RFIC, so that RFIC transmits the target transmission signal to the network device through the digital radio frequency front end.

[0051] In step S703, a network device is an entity on the network side used to transmit or receive signals. A network device can be a device in a wireless network, such as an evolved LTE base station or a new radio controller; it can be a base station in a 5G system or a centralized network element.

[0052] In step S703, after the target communication module is determined, the signal output by the BBIC in real time is switched to the signal output by the target communication module on the BBIC side, that is, the UL service is switched. For example, before the signal switching, that is, before the UL service switching, the BBIC outputs the signal output by the NR communication module in real time. According to the service requirements, the BBIC determines that the signal output by the LTE communication module needs to be transmitted to the RFIC. At this time, the BBIC performs the UL service switching, and after the service switching, it outputs the signal output by the LTE communication module to the RFIC side. Thus, the RFIC side does not need to perform UL service switching again, ensuring the integrity of the UL service and reducing the latency of UL service switching. At the same time, on the RFIC side, since the RFIC only receives one type of signal, that is, the signal output by the LTE side, the RFIC side only needs to use one DFE for signal processing.

[0053] As an example, to improve the efficiency of signal transmission on the RFIC side, an NR DFE is used on the RFIC side to transmit the signal output from the BBIC side. That is, regardless of whether the BBIC side outputs a signal corresponding to the NR module or the LTE module, the NR-corresponding DFE is used on the RFIC side.

[0054] Based on the scheme defined in steps S701 to S703 above, it can be understood that in this embodiment, the handover of UL services is implemented on the BBIC side, while the RFIC side uses a single digital radio frequency front-end to process UL services. This advances the handover timing of shared UL services to the BBIC side, thereby shortening the handover time between NR and LTE UL services and reducing the latency of UL service handover. Furthermore, in this embodiment, since the UL service handover is completed on the BBIC side, the impact of UL service handover on the integrity of UL services on the RFIC side is avoided, ensuring the integrity of UL services.

[0055] Therefore, the solution provided by the embodiments of this application takes into account both the handover time of UL services and the integrity of UL services, thus solving the problem of incompatibility between handover time and the integrity of UL services in related technologies.

[0056] The methods provided in the embodiments of this application will be explained in detail below.

[0057] After switching to UL services, BBIC needs to check whether the signal information of the terminal equipment matches in the NR network and the LTE network.

[0058] Specifically, BBIC extracts the first frequency and first bandwidth required for the terminal device to communicate in the NR network from the first signal information; at the same time, it extracts the second frequency and second bandwidth required for the terminal device to communicate in the LTE network from the second signal information; then, it compares the first frequency with the second frequency and compares the first bandwidth with the second bandwidth to obtain the signal comparison result; when the signal comparison result indicates that the first frequency and the second frequency are the same, and the first bandwidth and the second bandwidth are the same, it determines that the first signal information and the second signal information match.

[0059] In other words, the first signal information and the second signal information are only considered identical when both the frequency and bandwidth are the same. If any one or more of the frequencies or bandwidths differ, i.e., when there is a difference between the first and second signal information, the fifth transmission signal output by the NR communication module and the sixth transmission signal output by the LTE communication module in the BBIC are output to the RFIC. This allows the RFIC to determine the target transmission signal from the fifth and sixth transmission signals and switch the real-time signal output by the RFIC to the target transmission signal. Specifically, when there is a difference between the first and second transmission signals, the RFIC performs the UL service switching. In this case, the signals output by the two communication modules pass through the corresponding DFE and DAC, and the UL service switching is achieved by the analog switches in the RFIC.

[0060] It should be noted that when there is a difference between the first transmitted signal and the second transmitted signal, the solution in the relevant technology is adopted, namely... Figure 5 The architecture shown enables the switching of UL services, avoiding the problem of incomplete coverage of business scenarios.

[0061] Furthermore, when the first signal information matches the second signal information, the BBIC determines the target communication module for the output signal and switches the real-time transmission signal output by the BBIC to the target transmission signal output by the target communication module.

[0062] Specifically, BBIC determines the signal switching time for switching the real-time transmission signal based on the signal switching instruction, and switches the real-time transmission signal to the target transmission signal during the signal switching time.

[0063] It should be noted that, in the embodiments of this application, the signal switching time includes a first switching time for segmenting the real-time transmission signal and a second switching time for segmenting the target transmission signal. For transmission signals output by different communication modules, the BBIC uses different segmentation intervals to segment the transmission signals. For example, when the BBIC segments the signal output by the LTE communication module, its corresponding segmentation interval is 1ms, while when it segments the signal output by the NR communication module, its corresponding segmentation interval is 0.5ms. That is, the segmentation intervals corresponding to different communication modules are integer multiples of each other.

[0064] As an example, in Figure 8 In the signal switching diagram shown, BBIC needs to switch the signal output by the LTE communication module to the signal output by the NR communication module. The signal switching time is t, but the segmentation interval corresponding to the LTE communication module is 1ms, and the segmentation interval corresponding to the NR communication module is 0.5ms. For the LTE communication module, its corresponding signal switching time is t1 to t1+1. Since t is within the time range of t1 to t1+1, the signal output by the LTE communication module is switched at t1, which is the first switching time. For the NR communication module, its corresponding signal switching time is t2 to t2+0.5. Since t is within the time range of t2 to t2+0.5, the signal output by the NR communication module is switched at t2, which is the second switching time.

[0065] After determining the first switching time and the second switching time, the BBIC can segment the real-time transmission signal based on the first switching time to obtain the first transmission signal, and segment the target transmission signal based on the second switching time to obtain the second transmission signal; then sequentially send the first transmission signal and the second transmission signal to the RFIC.

[0066] In the above embodiments, the first transmission signal includes data of the real-time transmission signal prior to the first switching time, and the second transmission signal includes data of the target transmission signal prior to the second switching time. For example, in Figure 8 In this process, the signal output by the LTE communication module is the LTE subframe signal, and the signal output by the NR communication module is the NR timeslot signal. The LTE subframe signal is switched at time t1 to obtain the first transmission signal, i.e. Figure 8 The signal on the left at time t1; at time t2, the NR time slot signal is switched to obtain the second transmission signal, i.e. Figure 8 The signal on the right side at time t2.

[0067] During the process of sequentially transmitting the first transmission signal and the second transmission signal to the RFIC, if the first switching time is earlier than the second switching time, the BBIC determines the first switching duration between the first switching time and the second switching time, and obtains the third transmission signal transmitted within the first switching duration of the real-time transmission signal; then the first transmission signal, the third transmission signal and the second transmission signal are sequentially transmitted to the RFIC.

[0068] For example, in Figure 8 In the signal handover diagram shown, the subframe or time slot after the handover has a timing lag, i.e., t1 is earlier than t2. At this time, the time difference between t1 and t2 is the first handover duration. In this scenario, BBIC maintains the signal within the first handover duration as the data before the signal handover, i.e., the third transmitted signal is the LTE subframe signal between t1 and t2.

[0069] If the first switching time is later than the second switching time, the BBIC determines the second switching duration between the first and second switching times and obtains the fourth transmission signal transmitted by the real-time transmission signal during the second switching duration; removes the fourth transmission signal from the first transmission signal and transmits the updated second transmission signal and the fourth transmission signal to the RFIC in sequence; or, removes the fourth transmission signal from the second transmission signal and transmits the first transmission signal and the updated second transmission signal to the RFIC in sequence.

[0070] For example, in Figure 9In the signal switching diagram shown, the timing of the subframe or time slot after the switch is advanced, i.e., t1 is later than t2. At this time, there is an overlapping portion of the signal between the first and second transmission signals (i.e., the fourth transmission signal). This overlapping portion of the signal needs to be deduplicated, i.e., data deletion. In this scenario, the time difference between t2 and t1 is the second switching duration. BBIC deletes the tail data of the subframe or time slot signal before the signal switch, or deletes the head data of the time slot or subframe signal after the signal switch, i.e., removes the fourth transmission signal from the tail of the first transmission signal, or removes the fourth transmission signal from the head of the second transmission signal. For example, in... Figure 9 In this process, the signal output by the NR communication module is switched to the signal output by the LTE communication module. The corresponding switching time for LTE is advanced. At this time, it is necessary to delete the tail data of the NR timeslot signal or delete the header data of the LTE subframe signal.

[0071] It should be noted that in practical applications, the RFIC transmits signals from different communication modules to network devices at different power levels. Therefore, after receiving the switched output signal (i.e., the target output signal), the RFIC still needs to adjust the power of the target output signal. To enable the RFIC to accurately adjust the power of the target output signal, the BBIC also generates a power adjustment command before transmitting the target output signal to the RFIC.

[0072] Specifically, before sequentially transmitting the first and second transmission signals to the RFIC, the BBIC compares the power of the first transmission signal with the power of the second transmission signal to obtain a power comparison result. If the power comparison result indicates that there is a difference between the power of the first and second transmission signals, a power adjustment command is generated based on the second switching time. The power adjustment command is sent to the RFIC so that the RFIC adjusts the signal transmission power during the second switching time.

[0073] For example, in Figure 10 In the signal handover diagram shown, transmitting the signal output from the NR communication module requires higher power, while transmitting the signal output from the LTE communication module requires lower power. Before the handover, the RFIC transmits the signal output from the LTE communication module to the network device using lower power; after the handover, the RFIC increases the signal transmission power during the second handover time and uses the adjusted signal transmission power to transmit the signal output from the NR communication module to the network device during the second handover time.

[0074] For example, in Figure 11In the signal handover diagram shown, transmitting the signal output from the NR communication module requires higher power, while transmitting the signal output from the LTE communication module requires lower power. Before the handover, the RFIC transmits the signal output from the NR communication module to the network device using higher power; after the handover, the RFIC reduces the signal transmission power during the second handover time and uses the adjusted signal transmission power to transmit the signal output from the LTE communication module to the network device during the second handover time.

[0075] As can be seen from the above, in this embodiment, when the frequencies and bandwidths corresponding to NR and LTE are consistent, the handover shared by UL is moved from the RFIC side to the BBIC side, thereby saving the overall handover time for UL services, reducing handover latency, and better meeting protocol requirements, thus reducing the impact of handover on UL services. When the frequencies and bandwidths corresponding to NR and LTE are inconsistent, the solution in related technologies is used to implement the handover of UL services, avoiding the problem of incomplete scenario coverage.

[0076] This application also provides a communication device based on uplink sharing, applied in the baseband processing chip BBIC of a terminal device. The BBIC includes at least a new radio (NR) communication module and a long-term evolution (LTE) communication module. Figure 12 As shown, the device 1200 includes: a signal matching module 1201, a signal determination module 1202, and a signal switching module 1203.

[0077] The signal matching module 1201 is used to respond to the signal switching command and detect whether the first signal information of the terminal device in the NR network and the second signal information of the terminal device in the LTE network match.

[0078] The signal determination module 1202 is used to determine the target communication module from the NR communication module and the LTE communication module according to the service requirement information when the first signal information matches the second signal information.

[0079] The signal switching module 1203 is used to switch the real-time transmission signal output by the BBIC to the target transmission signal output by the target communication module, and transmit the target transmission signal to the radio frequency processing chip RFIC, so that the RFIC can transmit the target transmission signal to the network device through the digital radio frequency front end.

[0080] In one example, the signal matching module is specifically used to extract the first frequency and first bandwidth required for the terminal device to communicate in the NR network from the first signal information; extract the second frequency and second bandwidth required for the terminal device to communicate in the LTE network from the second signal information; compare the first frequency and the second frequency, and compare the first bandwidth and the second bandwidth to obtain a signal matching result; when the signal matching result indicates that the first frequency and the second frequency are the same, and the first bandwidth and the second bandwidth are the same, determine that the first signal information and the second signal information are matched.

[0081] In one example, the signal switching module is specifically used to determine the signal switching time for switching the real-time transmission signal according to the signal switching instruction; at the signal switching time, the real-time transmission signal is switched to the target transmission signal.

[0082] In one example, the signal switching time includes a first switching time for segmenting the real-time transmission signal and a second switching time for segmenting the target transmission signal. The signal switching module includes a first segmentation module, a second segmentation module, and a first transmission module.

The second segmentation module is used to segment the target transmission signal based on the second switching time to obtain a second transmission signal, wherein the second transmission signal contains data of the target transmission signal prior to the second switching time. The first transmission module is used to sequentially transmit the first transmission signal and the second transmission signal to the RFIC.

[0083] In one example, the first transmission module is specifically used to determine the first switching duration between the first switching time and the second switching time when the first switching time is earlier than the second switching time; to obtain the third transmission signal transmitted by the real-time transmission signal within the first switching duration; and to transmit the first transmission signal, the third transmission signal and the second transmission signal to the RFIC in sequence.

[0084] In one example, the first transmission module is specifically used to determine a second switching duration between the first switching time and the second switching time when the first switching time is later than the second switching time; obtain a fourth transmission signal transmitted by the real-time transmission signal during the second switching duration; remove the fourth transmission signal from the first transmission signal and transmit the updated second transmission signal and the fourth transmission signal to the RFIC in sequence; or, remove the fourth transmission signal from the second transmission signal and transmit the first transmission signal and the updated second transmission signal to the RFIC in sequence.

[0085] In one example, the communication device based on uplink sharing further includes: a power adjustment module, configured to compare the power of the first transmission signal with the power of the second transmission signal before sequentially transmitting the first transmission signal and the second transmission signal to the RFIC, and obtain a power comparison result; if the power comparison result indicates that there is a difference between the power of the first transmission signal and the power of the second transmission signal, generate a power adjustment instruction based on a second switching time; and send the power adjustment instruction to the RFIC, wherein the power adjustment instruction is used to instruct the RFIC to adjust the signal transmission power during the second switching time.

[0086] In one example, the communication device based on uplink sharing further includes: a service switching module, used to output the fifth transmission signal output by the NR communication module and the sixth transmission signal output by the LTE communication module to the RFIC when there is a difference between the first signal information and the second signal information, so that the RFIC can determine the target transmission signal from the fifth transmission signal and the sixth transmission signal, and switch the real-time signal output by the RFIC to the target transmission signal.
