[0002] In the field of wireless communication, Multiple-Input Multiple-Output (MIMO) and carrier aggregation technologies have been widely adopted to improve system capacity and spectral efficiency. MIMO utilizes multiple antennas to create spatial degrees of freedom, while carrier aggregation expands transmission bandwidth by aggregating multiple component carriers. In existing solutions, the mapping relationship between multiple antennas and multiple component carriers is often static or semi-static. However, fixed mapping methods cannot adapt to time-varying wireless channels, fluctuating service loads, and differences in quality of service requirements among different component carriers, potentially leading to underutilization of wireless communication system capacity, insufficient guarantee of high-priority services, or low overall energy efficiency.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application more apparent, exemplary embodiments according to this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0022] Figure 1 The illustration shows an overall flowchart of an antenna dynamic switching method according to an embodiment of this application.

[0023] like Figure 1 As shown, the steps are as follows: S101, acquire the wireless channel measurement results from all antennas to the component carriers. Specifically, receive the reference signal on each component carrier, analyze it, and perform channel measurements to collect a series of parameters characterizing the wireless channel, including but not limited to: reference signal received power, signal-to-noise ratio, signal-to-interference-plus-noise ratio, packet error rate, frequency deviation, and Doppler shift. Integrate all the relevant data obtained from the measurements into structured wireless channel measurement results.

[0024] S102, based on the wireless channel measurement results and the predetermined antenna dynamic handover target, determine the mapping allocation relationship between the antenna and component carriers. The predetermined antenna dynamic handover target determines the direction of optimized communication performance for antenna allocation and handover. Based on the obtained wireless channel measurement results and combined with the currently selected antenna dynamic handover target, evaluate and calculate possible mapping combinations of antennas and component carriers to quantify the expected contribution of each possible mapping allocation relationship to achieving the antenna dynamic handover target, and further optimize, selecting a mapping allocation relationship from the possible relationships that makes the antenna dynamic handover target tend to be optimal.

[0025] S103, based on the determined mapping allocation relationship, perform the switching of the mapping relationship between the antenna and the component carrier. Generate corresponding switching control commands based on the obtained mapping allocation relationship, drive each antenna and component carrier to perform physical or logical mapping relationship switching, specifically change the mapping state between each antenna and the corresponding component carrier's transmit RF channel and receive RF channel, so that the antenna resources are mapped to different component carriers according to the new mapping allocation relationship.

[0026] S104. After the mapping relationship switch is completed, monitor and evaluate the current communication performance indicators. Communication performance indicators include system throughput, link reliability, coverage level, and device power consumption. By monitoring and evaluating the communication performance indicators, determine whether the mapping relationship switch was effective and whether the predetermined antenna dynamic switching target was achieved.

[0027] Figure 2 The illustration shows a schematic diagram of a wireless channel measurement process according to an embodiment of the present application for an antenna dynamic switching method.

[0028] like Figure 2 As shown, the steps are as follows: S201, Determine the antenna and component carrier combination to be measured. Based on the activated component carriers and all available antennas, generate all possible antenna and component carrier mapping combinations. Through full measurement or selective measurement based on historical channels, determine the specific antenna and component carrier combination to be measured from all possible antenna and component carrier mapping combinations, and form the corresponding measurement task.

[0029] S202: Acquire relevant channel parameters from each antenna to each component carrier. For each measurement task, receive and analyze the reference signal on the specified component carrier. Through physical layer processing of the reference signal, directly measure or calculate the relevant channel parameters, including reference signal received power, signal-to-noise ratio, signal-to-interference-plus-noise ratio, packet error rate, frequency deviation, and Doppler shift.

[0030] S203, preprocess the acquired raw channel parameters to generate wireless channel measurement results. Specifically, after the relevant raw channel parameters are acquired, data preprocessing operations are performed, including but not limited to: filtering or averaging multiple sampled values ​​to suppress noise; normalizing or scaling parameters of different types or dimensions to make them within a uniform numerical range or comparable dimension; and integrating and encapsulating parameter data from different antennas and different component carriers according to a predefined structure to finally obtain structured wireless channel measurement results, which include the current wireless channel status between all measured antennas and component carriers.

[0031] Figure 3 The illustration shows a schematic diagram of the mapping relationship determination process of an antenna dynamic switching method according to an embodiment of this application.

[0032] like Figure 3 As shown, the steps are as follows: S301, based on the predetermined antenna dynamic switching objective, determine the corresponding optimization strategy. The predetermined antenna dynamic switching objective includes various communication performance optimization directions, such as maximizing overall capacity, maximizing overall coverage, maximizing overall communication reliability, optimizing the balance between capacity, coverage, and reliability, minimizing overall energy consumption, or prioritizing specific target component carriers. The antenna dynamic switching objective can be determined based on the current communication scenario, service requirements, or network commands. Based on the selected antenna dynamic switching objective, a matching optimization strategy is determined. This optimization strategy further determines the optimization algorithm used to evaluate and compare the specific communication performance and constraint satisfaction of different mapping relationships.

[0033] In some embodiments, the goal of dynamic antenna switching can be determined as achieving an optimal balance between the overall transmit or receive capacity, coverage, and communication reliability of all component carriers. To achieve this optimization goal, a weighted comprehensive scoring method can be used to evaluate each possible mapping assignment relationship. Specifically, based on wireless channel measurement results, the total communication system capacity, average communication system coverage index, and worst-case reliability index of the communication system corresponding to each mapping assignment relationship are calculated.

[0034] Similarly, the target of dynamic antenna switching can also be determined for one or more selected component carriers, prioritizing the maximization of their transmission or reception capacity, coverage, or communication reliability. For example, target component carriers that need to be prioritized can be identified based on service priorities or network instructions, and antenna resources with optimal channel conditions can be preferentially allocated to these target component carriers based on wireless channel measurement results, in order to achieve targeted optimization of the specific performance of these component carriers.

[0035] S302, based on the obtained wireless channel measurement results and the determined optimization strategy, calculate the mapping allocation relationship between the antenna and component carriers. Based on the wireless channel measurement results and the determined optimization strategy, construct an optimization model including the objective function and constraints. Based on the optimization model, traverse all possible combinations of antenna and component carrier mapping relationships, or quickly obtain the optimal mapping allocation relationship through an optimization algorithm. For each possible mapping allocation relationship, calculate its corresponding objective function value, such as estimated total capacity, total power consumption, and worst-case reliability, based on measurement results such as the channel capacity matrix and channel quality matrix.

[0036] S303, Perform performance and conflict verification on the mapping and allocation relationship. If the performance verification result reaches the performance index threshold corresponding to the predetermined handover target, and the conflict verification confirms that the new mapping and allocation relationship has no constraint conflict corresponding to the antenna dynamic handover target, then the final mapping and allocation relationship between the antenna and the component carrier is determined.

[0037] Figure 4 The diagram illustrates a mapping relationship switching process of an antenna dynamic switching method according to an embodiment of this application.

[0038] like Figure 4 As shown, the steps are as follows: S401 generates corresponding switching control commands based on the determined mapping and allocation relationship. The switching control commands specifically include: specifying the port number of the RF switch matrix or tunable network to be operated, setting the mapping state of each path, configuring the operating frequency band and bandwidth of the corresponding RF front-end modules such as power amplifiers and low-noise amplifiers to match the target component carrier, and the timing sequence of each switching action to ensure that the switching process is orderly and avoids signal conflicts.

[0039] S402, according to the switching control command, complete the mapping switching of each antenna and each component carrier's transmit and receive channels. The mapping switching is completed based on the generated switching control command. Specifically, for the transmit path, the signal of the transmit link corresponding to the target component carrier is input to the designated antenna; for the receive path, the signal of the designated antenna is output to the receive link corresponding to the target component carrier.

[0040] S403: After the mapping handover operation is completed, the mapping status between the antenna and component carriers is verified. After the handover is completed, the new mapping status is verified. Specifically, this is achieved by sending test signals or detecting normal operating reference signals. For example, a known probe signal is sent through the newly established link, and the receiver checks whether the signal is correctly received; or the physical layer indicators corresponding to the new link, such as the initial synchronization signal strength and carrier aggregation configuration feedback, are directly monitored. If the verification results show that all expected antenna and component carrier mappings have been correctly established and are working normally, the handover is confirmed as successful, and the mapping status table is updated. If any mapping anomaly is found, the anomaly is recorded and an alarm is triggered, and the system reverts to the previous valid configuration.

[0041] Figure 5 The illustration shows a schematic diagram of an antenna allocation process for maximizing the overall capacity of an antenna dynamic switching method according to an embodiment of this application.

[0042] like Figure 5 As shown, the steps are as follows: S501, based on wireless channel measurement results, evaluates the potential capacity contribution of each antenna to each component carrier. Based on the obtained wireless channel measurement results, the channel quality parameters are converted into theoretical data rates or spectral efficiency estimates that the link can support under ideal or typical coding and modulation schemes. Considering factors such as channel bandwidth, coding gain, and implementation losses, a quantified potential capacity contribution value is calculated for each antenna to each component carrier. This potential capacity contribution value characterizes the expected increase in overall capacity when this antenna is allocated to that component carrier.

[0043] (Formula 1) Formula 1 is the capacity calculation formula for multiple-input multiple-output scenarios, used for quantizing antennas. With component carrier The potential capacity contribution of the constructed multi-input multi-output link is evaluated from the overall dimension of the multi-antenna channel matrix, where Indicates antenna With component carrier The potential capacity of multiple input multiple output links Indicates component carrier bandwidth, This is a determinant operation used to characterize the joint gain of the multi-input multi-output channel matrix to reflect the cooperative transmission effect of multiple antennas. For dimension equal to The identity matrix, For antenna Received component carrier Number of receiving antennas at that time For antenna To component carrier The total average transmit power of the transmitted signal, For antenna To component carrier The number of transmitting antennas when transmitting signals. For antenna With component carrier The multi-input multi-output channel matrix between them has a dimension of . Its matrix elements reflect the transmission characteristics such as channel attenuation and phase shift from a single transmitting antenna to a single receiving antenna. Channel matrix The conjugate transpose of the matrix is ​​used to calculate the power gain of the channel, thereby reflecting the combining gain effect of the multi-antenna receiver.

[0044] S502, construct the capacity contribution matrix of antennas and component carriers, and calculate the total capacity corresponding to each mapping allocation relationship based on this matrix. Based on the calculated potential capacity contribution values ​​of all antennas and component carriers, a capacity contribution matrix is ​​obtained. This matrix is ​​a two-dimensional matrix, with rows corresponding to all available antennas and columns corresponding to all configured component carriers. Each matrix element is the corresponding overall capacity contribution value. For a given mapping allocation relationship, it specifies which antenna(s) serve each component carrier. According to this mapping allocation relationship, extract the potential capacity contribution value of each antenna for that component carrier from the capacity contribution matrix, and aggregate these potential capacity contribution values ​​by component carrier to calculate the theoretical overall total capacity that the entire wireless communication system can obtain under this mapping allocation relationship.

[0045] (Formula 2) Formula 2 is used to aggregate the total capacity, where, For the overall total capacity of the communication system, Assign an identifier to the binary. Indicates antenna Assigned to component carrier , This indicates no allocation. The total number of component carriers, This represents the total number of antennas.

[0046] S503, an optimization algorithm is used to select the mapping allocation relationship that maximizes the overall total capacity from all possible mapping allocation relationships. With the goal of maximizing the overall total capacity, an optimization search is performed under preset constraints, such as each antenna serving at most one component carrier at any given time and each component carrier being allocated at least one antenna. The optimization algorithm can be, for example, the Hungarian algorithm for bipartite graph matching, or a heuristic algorithm such as a greedy algorithm or a genetic algorithm. The algorithm searches for feasible antenna and component carrier combinations, calculating the corresponding overall total capacity for each evaluated mapping allocation relationship. The mapping allocation relationship that maximizes the overall total capacity is determined as the final antenna and component carrier mapping allocation relationship aimed at maximizing the overall capacity.

[0047] Figure 6 The illustration shows a schematic diagram of an antenna allocation process based on quality of service requirements for a dynamic antenna switching method according to an embodiment of this application.

[0048] like Figure 6 As shown, the steps are as follows: S601, based on the service quality requirements of each component carrier, determine the target component carriers that need to be prioritized. Obtain the service quality requirement information of the services carried by each component carrier, including service type identifier, priority level, or quantified performance indicator requirements such as minimum guaranteed bit rate, maximum allowable latency, and maximum acceptable packet error rate. Based on the service quality requirements, identify one or more component carriers with the most stringent requirements or the highest priority, and mark them as the target component carriers to be prioritized, so as to ensure that wireless communication resources can be tilted towards the most critical services.

[0049] S602, based on wireless channel measurement results, evaluates the communication quality support capability of each antenna for the target component carrier. For each identified target component carrier, combined with the wireless channel measurement results, it analyzes the potential support capability of the channel conditions from each available antenna to that target component carrier for meeting its specific quality of service requirements. For example, for services requiring high reliability, the focus is on evaluating the signal-to-interference-plus-noise ratio from the antenna to that component carrier and its impact on the packet error rate; for services requiring high throughput, the focus is on evaluating the potential channel capacity from the antenna to that component carrier.

[0050] (Formula 3) Formula 3 is used to determine whether the antenna meets the service quality requirements of the target component carrier, where, To indicate the degree of satisfaction, 1 represents satisfaction and 0 represents dissatisfaction. To calculate the potential capacity, Component carrier The minimum service quality requirements.

[0051] S603, based on the evaluation results, at least one antenna that meets the communication quality support requirements is assigned to the target component carrier. Based on the evaluation results, available antennas with optimal or satisfactory communication quality support capabilities are selected for each target component carrier. Subsequently, one or more selected antennas are bound to their corresponding target component carriers. During allocation, if multiple target component carriers compete for the same antenna, they can be allocated sequentially according to their relative priority or urgency of service quality requirements to ensure that high service quality requirements are met.

[0052] S604: After prioritizing the target component carriers, antenna allocation is performed on the remaining component carriers, and the mapping relationship between each antenna and the component carriers is finally determined. After ensuring that all target component carriers have at least one antenna that meets their service requirements, the remaining non-priority component carriers and unallocated antenna resources are processed. For the remaining component carriers, different optimization objectives, such as load-based balanced allocation or channel condition-based capacity maximization, can be used for subsequent antenna allocation. Finally, based on the allocation of priority target component carriers and non-priority component carriers, a complete mapping relationship between antennas and all component carriers is formed.

[0053] Figure 7 The illustration shows a schematic diagram of an antenna allocation process based on component carrier load state in an antenna dynamic switching method according to an embodiment of this application.

[0054] S701, based on the load status of each component carrier, determine the target component carriers whose load exceeds a preset threshold and require priority protection. Monitor the service load information carried by each component carrier, including at least one of data queue length, throughput demand, resource block utilization, or service data rate. By comparing the current load of each component carrier with a preset load threshold, identify component carriers whose load level exceeds the load threshold. Determine these high-load component carriers as the target component carriers that currently require priority resource protection to ensure that their congestion is alleviated.

[0055] (Formula 4) Formula 4 is used to quantize component carrier load, where, Component carrier Normalized load, Component carrier The current length of the data queue. This represents the maximum allowed queue length for component carriers.

[0056] S702, based on wireless channel measurement results, evaluates and compares the communication support capabilities of each antenna to the target component carrier. For each high-load target component carrier, based on the wireless channel measurement results, it evaluates and compares the potential data transmission performance of each available antenna link to the target component carrier, especially its expected capacity contribution under the current channel conditions, thereby further ranking and comparing the throughput gain that each antenna can bring to the high-load target component carrier.

[0057] S703, based on the evaluation results, allocates one or more antennas with optimal communication support capabilities to the target component carrier. Based on the evaluation and comparison results, it selects one or more antennas with the largest expected capacity contribution, i.e., the optimal communication support capability, for each high-load target component carrier. Subsequently, the selected optimal antenna resources are bound to the corresponding target component carrier.

[0058] S704, after ensuring priority allocation of high-load component carriers, allocates remaining antenna resources to the remaining component carriers and finally determines the mapping and allocation relationship between each antenna and component carrier. After ensuring that all high-load target component carriers have obtained optimal antenna resources, it processes the remaining non-high-load component carriers and antennas that have not yet been allocated. For the remaining antennas and component carriers, different antenna optimization objectives can be adopted, such as cyclic allocation or simple matching based on channel conditions. Finally, based on the integration of the allocation for high-load target component carriers and the allocation for the remaining component carriers, a complete mapping and allocation relationship between antennas and all component carriers is generated.

[0059] Figure 8 The illustration shows a schematic diagram of the antenna allocation process with primary carrier priority protection in an antenna dynamic switching method according to an embodiment of this application.

[0060] like Figure 8 As shown, the steps are as follows: S801: Determine the current primary carrier and designate it as the target component carrier to be prioritized in antenna allocation. Based on the configuration of the wireless communication protocol stack or signaling from the network side, the primary carrier in the current serving cell is obtained. In carrier aggregation scenarios, the primary carrier carries critical system signaling and some user plane data; its stability and performance have a fundamental impact on overall communication. Therefore, this primary carrier is designated as the target component carrier requiring priority resource protection.

[0061] S802, based on wireless channel measurement results, evaluates and compares the channel quality indicators of each antenna to the main carrier. It acquires the channel parameters from all available antennas to the main carrier from the wireless channel measurement results, including parameters that directly reflect link reliability and signal strength, such as reference signal received power and signal-to-interference-plus-noise ratio. By quantitatively analyzing and comparing these communication indicators, it ranks the link quality between each antenna and the main carrier, thereby identifying which antennas can provide the best channel conditions to ensure main carrier communication.

[0062] (Formula 5) Formula 5 is the formula for calculating the overall channel quality between the quantized antenna and the main carrier. Wherein, This represents the overall channel quality score of the antenna and the main carrier. The higher the value, the stronger the antenna's communication support capability for the main carrier, and the higher its allocation priority. yes The weighting coefficients are used to adjust the proportion of signal strength in the overall channel quality calculation. yes The weighting coefficients are used to adjust the proportion of anti-interference capability; without loss of generality, they can make... and , . This refers to the average power of the antenna receiving the main carrier reference signal, which characterizes the actual received strength of the main carrier signal. The larger the value, the smaller the signal propagation loss. The ratio of signal to interference plus noise when the antenna receives the main carrier reflects the prominence of the main carrier signal in interference and noise. The higher the value, the higher the stability of the communication link.

[0063] S803, based on the channel quality assessment results, allocates one or more antennas with the best channel quality to the main carrier. Based on the assessment and ranking results, and by binding one, several, or all antennas with the best channel quality to the main carrier, it ensures that the main carrier obtains the highest quality radio link resources, thereby guaranteeing the reliability and performance of its signaling transmission and basic data services.

[0064] S804, after prioritizing the primary carrier, allocates the remaining antenna resources to other component carriers and ultimately determines the mapping relationship between each antenna and the component carriers. After satisfying the primary carrier's priority allocation, the remaining secondary carriers can be allocated antennas based on other optimization objectives such as capacity maximization and load balancing. Finally, the allocations for the primary carrier and secondary carriers are integrated to generate a complete mapping relationship between antennas and all component carriers.

[0065] Figure 9The illustration shows a schematic diagram of an antenna allocation process based on the number of enabled component carriers in an antenna dynamic switching method according to an embodiment of this application.

[0066] like Figure 9 As shown, the steps are as follows: S901, obtain the number of component carriers currently in the enabled state. This is done by querying the carrier aggregation configuration of the protocol stack or detecting the activation status of the RF front-end. Enabled component carriers do not include those that are configured but are in a deactivated, dormant, or faulty state.

[0067] S902, based on the number of enabled component carriers, select the corresponding antenna resource allocation strategy. According to the acquired number of enabled component carriers, select the appropriate antenna allocation mode. For example, if only one component carrier is currently enabled, a centralized allocation strategy is selected, aiming to concentrate most or all available antennas to serve that component carrier to maximize its performance. If multiple enabled component carriers exist, a distributed allocation strategy is selected, aiming to rationally allocate antenna resources among the multiple component carriers. Through the above strategy selection, an adaptive match is achieved between the antenna resource pool size and service carrier requirements.

[0068] S903, based on the wireless channel measurement results, allocates at least one antenna to each enabled component carrier according to the selected antenna resource allocation strategy. In centralized allocation mode, all antennas, or the antennas with the best channel conditions, are allocated to the only enabled component carrier. In distributed allocation mode, antenna resources are divided into a corresponding number of groups or pools based on the number of enabled component carriers. Then, based on the wireless channel measurement results, at least one antenna is allocated to each component carrier from its corresponding resource pool. Further optimization can be performed during allocation to balance channel quality or maximize performance among the component carriers.

[0069] (Formula 6) Formula 6 indicates that when only one component carrier is enabled, all Each antenna is assigned to that component carrier.

[0070] (Formula 7) Formula 7 indicates that when there is When one component carrier is enabled, Each antenna is evenly distributed among the enabled component carriers.

[0071] S904, the final mapping and allocation relationship between the antenna and each enabled component carrier is obtained. Specifically, the antennas allocated to each enabled component carrier are integrated to obtain the complete mapping and allocation relationship.

[0082] like Figure 12 As shown, the allocation decision module 1002 includes a target setting submodule 1006 and a decision calculation submodule 1007.

[0083] The target setting submodule 1006 is configured to store, manage, and recall predetermined antenna dynamic switching targets.
