[0002] In wireless communications, Multiple Input Multiple Output (MIMO) antenna systems leverage spatial resources to achieve multiple transmissions and multiple receptions using multiple antennas.

[0038] In order to make the purpose, technical solutions and advantages of the present disclosure more apparent, the following will describe in detail exemplary embodiments of the present disclosure with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the exemplary embodiments described herein.

[0039] Currently, in wireless communications, MIMO systems rely on detected wireless channel information to achieve efficient transmission. This information includes, but is not limited to, path loss information and frequency or phase information in the time, frequency, and spatial domains. To obtain this information, two terminal feedback modes—the Precoding Matrix Index (PMI), the Channel State Information Reference Signal (CSI-RS), and the Sounding Reference Signal (SRS)—can be used to obtain channel information.

[0040] Generally speaking, the PMI mode is that the base station sends the CSI-RS reference signal. After the terminal measures it, it estimates the downlink channel information and resource requirements through various quantization methods and reports this information to the base station. This mode is mainly used for obtaining downlink channel information and managing resource requirements.

[0041] The SRS mode, on the other hand, utilizes channel reciprocity to allow the terminal to directly report channel information to the base station. This mode is mainly used for uplink channel information acquisition and beam management. It should be noted that when the base station uses SRS to measure the uplink channel, the base station can configure up to 16 SRS resource sets for the user equipment (UE), with each resource set configured with up to 16 SRS resources, and the total number of SRS resources does not exceed 64. These resource sets can provide at least one of the following services based on their functions: beam management, uplink channel information acquisition based on a codebook uplink transmission scheme, uplink channel information acquisition based on a non-codebook uplink transmission scheme, and downlink channel information acquisition based on SRS antenna switching.

[0042] However, in current MIMO systems, variations in antenna characteristics within a symbol period can cause inter-carrier interference (ICI). When a terminal's antenna characteristics change within a symbol period, signals from different transmission channels overlap, making them difficult to distinguish. This makes it difficult for the base station to accurately obtain channel information, further reducing channel capacity and increasing bit error rates, thereby degrading communication system performance.

[0043] Therefore, this application proposes a communication method for enabling a base station to accurately obtain channel information and improve the performance of the communication system. Figure 1 The overview is an architectural diagram of the communication system. Figure 1 Figure 1 is a diagram showing the architecture of the communication system. Figure 1 , wherein the overall communication system includes: terminals and base stations.

[0044] A terminal device is a device that provides voice and / or data connections to users, or a chip set in the device, such as a handheld device with wireless connection capabilities, an in-vehicle device, etc. For example, user devices may include: mobile phones, tablets, laptops, PDAs, mobile Internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in unmanned driving, wireless terminals in remote surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc., without exhausting the list.

[0045] A base station, also known as a base station site or base station equipment, is one of the key devices in a wireless communication network. It is used to communicate and transmit data with terminal devices to achieve wireless communication coverage.

[0046] then, Figure 2 FIG is an interactive flow chart illustrating a communication method according to an embodiment of the present disclosure. Figure 2 As shown, the communication method according to the embodiment of the present disclosure includes the following steps:

[0047] S1: The terminal sends multiple sounding reference signals (SRSs) to the base station, where any one SRS signal corresponds to one symbol period and any one SRS signal corresponds to one antenna characteristic of the terminal.

[0048] In an embodiment of the present disclosure, a terminal sends multiple SRS signals to a base station. In the present disclosure, SRS is a sounding reference signal used to measure the terminal's channel information. Any one of the multiple SRS signals corresponds to one symbol period, and any one of the SRS signals corresponds to one antenna characteristic of the terminal. This is because when the terminal communicates with the base station, when the relevant antenna characteristics used in each symbol period change, it will cause ICI interference of the channel signal. Signals from different ports will overlap with each other within the symbol period, making it impossible for the base station to accurately obtain channel information. Based on this, the present disclosure defines multiple SRS signals, and any one of the SRS signals corresponds to one symbol period, and any one of the SRS signals corresponds to one antenna characteristic of the terminal. In layman's terms, an SRS signal with one antenna characteristic is sent separately within one symbol period, thus avoiding the problem of superposition of different antenna characteristics. It should be noted that because multiple SRS signals need to be sent within multiple symbol periods, in the present disclosure, the terminal sends multiple SRS signals to the base station in sequence, and any one of the SRS signals corresponds to one symbol period, and any one of the SRS signals corresponds to one antenna characteristic of the terminal.

[0049] In the embodiments of the present disclosure, the symbol period refers to the duration of a modulation symbol, which can be expressed as the baud rate or symbol rate of the signal. In a MIMO system, the symbol period is a key parameter that affects the accuracy of channel estimation and signal processing.

[0050] In the embodiments of the present disclosure, the antenna characteristics of a terminal include, but are not limited to, at least one of the following: simulated beam, antenna loading, array position, array angle, and reconfigurable smart surface characteristics. The antenna characteristics of a terminal play a key role in wireless communications and are of great significance in improving at least one of communication performance, coverage, service quality, and communication speed.

[0051] S2: The base station receives multiple SRS signals from the terminal.

[0052] In the present disclosure, the base station prepares conditions for the base station to subsequently determine an antenna switching combination for the terminal by receiving multiple SRS signals sent by the terminal.

[0053] Of course, before the base station receives multiple SRS signals from the terminal, it also includes:

[0054] The base station receives first information and second information reported by the terminal, wherein the first information includes antenna characteristic information and the second information includes signal channel information;

[0055] The base station configures an SRS resource set for the terminal based on the first information and the second information.

[0056] In the disclosed embodiment, the first information and the second information may be the antenna characteristic information and signal channel information of the terminal, respectively. The base station can configure an SRS resource set for the terminal based on the antenna characteristic information and signal channel information. This is because the antenna characteristic information and signal channel information can reflect the characteristics of the current communication environment. Antenna characteristics determine the coverage, strength, and directionality of the signal, while signal channel information reflects the quality, interference, and attenuation of the signal during transmission. This information is crucial for optimizing communication performance and ensuring stable signal transmission. By analyzing the antenna characteristic information and signal channel information, the base station can more accurately determine at least one of the terminal's location and communication needs. At the same time, the base station can understand the communication quality of the terminal's area and thus configure an appropriate SRS resource set for it.

[0057] In the disclosed embodiment, antenna characteristic information includes but is not limited to at least one of the following: simulated beam, antenna load, array position, array angle, reconfigurable smart surface characteristics, etc. Signal channel information includes but is not limited to the number of signal channels received and transmitted by the terminal.

[0058] First, the terminal reports its antenna characteristics and signal channel information to the base station. This information is crucial for the base station to understand channel status and perform resource allocation. Second, based on the antenna characteristics and signal channel information reported by the terminal, the base station configures a dedicated SRS resource set for the terminal. This resource set is used by the terminal to transmit SRS signals. By configuring an appropriate resource set, the base station can ensure accurate reception of multiple SRS signals from the terminal, thereby performing accurate channel estimation and performance optimization. The specific method for configuring an SRS resource set by a base station according to an embodiment of the present disclosure is described below.

[0059] S3: The base station determines the channel information corresponding to each antenna characteristic based on multiple SRS signals.

[0060] In the embodiment of the present disclosure, channel information includes but is not limited to at least one information such as signal strength, channel transmission interference level, channel noise ratio, bit error rate, channel communication delay, channel communication quality, and channel communication protocol information.

[0061] In an embodiment of the present disclosure, when the base station determines the channel information corresponding to each antenna characteristic based on multiple SRS signals, the channel information corresponding to each antenna characteristic can be obtained through steps such as receiving and detecting SRS signals, signal processing and denoising, channel estimation, and correspondence between antenna characteristics and channel information.

[0062] When a base station receives and detects SRS signals, it receives multiple SRS signals from a terminal, which can be transmitted via a wireless channel. The base station can perform necessary signal processing on the received SRS signals, including at least one operation such as denoising and filtering, to reduce the impact of channel noise and other interference. The base station can perform channel estimation based on the processed SRS signals. The present disclosure uses a channel estimation method to estimate channel parameters and obtain channel information. Ultimately, this channel information can correspond to the antenna characteristic information reported by the terminal, thereby establishing an association between the antenna characteristics and the channel information, allowing the base station to obtain the channel information corresponding to each antenna characteristic based on multiple SRS signals.

[0063] S4: The base station determines the target antenna switching combination based on the information of each channel.

[0064] In the embodiment of the present disclosure, the antenna switching combination includes at least one of a centralized MIMO antenna switching combination, a distributed MIMO antenna switching combination, a three-dimensional MIMO antenna switching combination, a smart MIMO antenna switching combination, a virtual MIMO antenna switching combination, and the like.

[0065] In an embodiment of the present disclosure, the base station determines the target antenna switching combination, i.e., the optimal antenna switching combination, based on the information of each channel. For example, for the uplink (communication from the terminal to the base station), the base station may select an antenna switching combination with lower interference and higher signal strength. For the downlink, the base station may select an optimal antenna switching combination that can evenly cover the target area and ensure signal quality. In actual operation, the base station also needs to consider other factors, such as at least one factor such as power consumption, equipment life, and resource utilization. It is worth noting that the determination of the antenna switching combination is not a one-time process. As the environment changes, the base station will dynamically adjust the antenna switching combination as needed. In some cases, the resources of the base station may be limited. At this time, the base station may determine the antenna switching combination based on the priority of the user (for example, at least one of paying users, high-value users, etc.) to ensure that the communication needs of these users are met. The specific method for determining the target antenna switching combination according to the embodiment of the present disclosure is described later.

[0066] S5: The base station sends instruction information to the terminal, where the instruction information is used to instruct the terminal to communicate according to the target antenna switching combination.

[0067] In the disclosed embodiments, the indication information includes multiple resource blocks, each of which corresponds to a resource set with antenna characteristics. The order of the multiple resource blocks indicates the order of antenna switching. Of course, the disclosure does not specifically limit the indication method; any customized indication method is acceptable. The specific configuration of the indication information according to the disclosed embodiments is described below.

[0068] In the embodiment of the present disclosure, the base station sends indication information to the terminal, and the indication information may instruct the terminal to communicate in the order of the target antenna switching combination.

[0069] In this way, the base station can dynamically instruct the terminal to switch to different antenna combinations to adapt to different communication environments and needs. This helps improve the reliability and efficiency of the communication system and ensures that the terminal can obtain the best communication performance.

[0070] S6: The terminal receives instruction information from the base station.

[0071] In the embodiment of the present disclosure, the base station can receive the indication information sent by the terminal through a specific communication channel. This specific communication channel ensures the reliability of information transmission.

[0072] In the above, the base station receives multiple SRS signals from the terminal, and each SRS signal corresponds to an antenna characteristic information for one symbol period. In this way, the base station can determine the channel information corresponding to all antenna characteristics of the terminal based on the multiple SRS signals and perform traversal calculations. The base station ultimately determines the optimal antenna combination and notifies the terminal, so that the terminal transmits communication information to the base station based on the optimal antenna switching combination. It should be noted that in the process of determining the optimal antenna combination, the base station sequentially receives the SRS signals with multiple antenna characteristics sent by the terminal in multiple symbol periods, thereby avoiding the generation of ICI interference. Compared with the prior art, when changes occur within a symbol period, different transmission channels will overlap with each other, resulting in the problem of being difficult to distinguish. In the present application, the base station can determine the channel information corresponding to all antenna characteristics of the terminal based on the SRS signals with different antenna characteristics corresponding to the terminal in different symbol periods, thereby determining the optimal antenna switching combination. Because only an SRS signal with one antenna characteristic is sent in a symbol period, the problem of overlapping different transmission channels is avoided. At the same time, the base station can also obtain accurate channel information, further improving the channel capacity and reducing the bit error rate, thereby improving the performance of the communication system.

[0073] As previously described, in the embodiments of the present disclosure, the base station receives multiple SRS signals transmitted by the terminal, and any one SRS signal corresponds to one symbol period and one terminal antenna characteristic. Because only one SRS signal with one antenna characteristic is transmitted within a symbol period, the overlap of different transmission channels is avoided. The base station can then determine the target antenna combination using multiple SRS signals and notify the terminal via indication information, allowing the terminal to communicate accordingly, thereby improving system performance. The following describes a possible implementation method for configuring an SRS resource set by a base station according to an embodiment of the present disclosure.

[0074] The method for configuring a resource set by a base station according to an embodiment of the present disclosure includes:

[0075] The base station configures a first SRS resource set corresponding to uplink channel transmission for the terminal based on antenna characteristic information; and / or the base station configures a second SRS resource set corresponding to downlink channel transmission for the terminal based on antenna characteristic information and signal channel information.

[0076] The first SRS resource set is an SRS resource set, the SRS resource set includes multiple SRS resources, and the SRS resources and SRS signals correspond one to one.

[0077] The second SRS resource set is a plurality of SRS resource sets, the plurality of SRS resource sets correspond one-to-one to the plurality of SRS signals, the SRS resource set includes a plurality of SRS resources, and the number of SRS resources is associated with the number of signal channels.

[0078] The association between the number of SRS resources and the number of signal channels includes: the ratio of the number of SRS resources to the number of signal channels received and sent in the number of signal channels is equal, wherein the number of signal channels includes the number of signal channels received and sent. Of course, in the present disclosure, the specific definition of the association between the number of SRS resources and the number of signal channels is not limited, and it can also be equal to an integer multiple of the ratio of the number of SRS resources to the number of signal channels received and sent in the signal channel. According to the settings of the customized SRS resources and the number of signal channels, the number of SRS resources is configured for the second SRS resource set. In an embodiment of the present disclosure, the base station will configure the SRS resource set for the terminal based on the antenna characteristic information and signal channel information reported by the terminal. The base station will configure the first SRS resource set corresponding to the uplink channel transmission for the terminal based on the antenna characteristic information and the signal channel information, and / or the base station will configure the second SRS resource set corresponding to the downlink channel transmission for the terminal based on the antenna characteristic information and the signal channel information.

[0079] Among them, the first SRS resource set for uplink channel transmission configured by the base station for the terminal is an SRS resource set, and this SRS resource set corresponds to multiple SRS resources, and the SRS resources and SRS signals correspond one to one. During uplink channel transmission, the base station can achieve resource multiplexing by allocating multiple SRS resources to one resource set. This means that in some cases, when certain resources are not used, they can be configured for other purposes or for the transmission of other signals. And the number of SRS resources in the uplink first SRS resource set of the present disclosure is equal to the number of SRS signals, and the SRS signal represents an antenna characteristic of the terminal within a symbol period, which can also be said to be equal to the number of SRS resources in the SRS resource set and the number of terminal antenna characteristics. Exemplarily, a schematic diagram of an SRS signal when a base station receives uplink channel transmission according to an embodiment of the present disclosure is shown below. Figure 3 Shown in.

[0080] The base station configures multiple SRS resource sets for downlink channel transmission for the terminal. These multiple SRS resource sets correspond one-to-one to multiple SRS signals, and each of these multiple SRS resource sets includes multiple SRS resources. The number of SRS resources is correlated with the number of signal channels. This is because, in SRS mode, the more antennas participating in SRS signal transmission, the more accurate the channel estimation and the higher the download rate. Therefore, for downlink channel transmission, multiple SRS resource sets are required. The number of SRS resource sets is equal to the number of SRS signals. Since an SRS signal represents the characteristics of one terminal antenna within a symbol period, the number of SRS resource sets is equivalent to the number of terminal antenna characteristics. By configuring multiple SRS resource sets, the base station can select appropriate antennas and times to transmit multiple SRS signals based on channel state fluctuations and communication requirements to meet communication needs. Each of these multiple SRS resource sets includes multiple SRS resources, and the number of SRS resources is correlated with the number of signal channels. This is because, due to terminal hardware and cost constraints, the number of transmit channels in a terminal may be fewer than the number of receive channels. In order to use reciprocity to detect downlink transmission paths, it is necessary to transmit SRS signals in rotation to understand the signal conditions of multiple downlink paths. Therefore, the number of resources in each SRS resource set is related to the signal path.

[0081] Among them, when the downlink channel is transmitted, the number of resources in each SRS resource set and the signal channel can be associated with the ratio of the number of SRS resources to the number of signal channels received and sent in the signal channel information, or can be equal to a multiple of the ratio of the number of SRS resources to the number of signal channels received and sent in the signal channel information, and the signal channel information includes the number of signal channels received and sent. For example, a schematic diagram of an SRS signal when a base station receives a downlink channel transmission according to an embodiment of the present disclosure is shown below. Figure 4 Shown in.

[0082] In the above, the base station configures different SRS resource sets for terminals based on antenna characteristics and signal channel information. This not only expands SRS resources, but also, due to the inherent limitations of the SRS signal, prevents signals from different transmission channels from overlapping within the same symbol period, thereby improving the performance of the entire communication system. The following illustrates, for example, a schematic diagram of a base station receiving SRS signals for uplink and downlink channel transmissions according to an embodiment of the present disclosure, and a schematic diagram of a base station determining resource sets based on different signal communication information during downlink channel transmission according to an embodiment of the present disclosure.

[0084] In the embodiment of the present disclosure, the SRS signal received by the base station of the embodiment of the present disclosure when transmitting an uplink signal is used for beam management.

[0085] In MIMO uplink transmission, the terminal uses a digital-analog hybrid antenna architecture to switch between multiple analog beams. f By switching between simulated beams and transmitting at different sampling points, the terminal can expand more transmission channels based on the actual physical channels. Since the uplink transmission performance will vary when switching between different beam combinations, it is necessary to use SRS to assist in determining the optimal uplink transmission beam combination.

[0086] Figure 4 1 is a schematic diagram illustrating an SRS signal when a base station receives downlink channel transmission according to an embodiment of the present disclosure. Figure 4 As shown:

[0087] In the embodiment of the present disclosure, the SRS signal received by the base station of the embodiment of the present disclosure when transmitting a downlink signal is used for beam management.

[0088] In MIMO downlink transmission, the terminal adopts a digital-analog hybrid antenna architecture to switch between multiple analog beams. f By switching between simulated beams and transmitting at different sampling points, the terminal can expand more transmission channels based on the actual physical channels. Since the downlink transmission performance will vary when switching between different beam combinations, it is necessary to use SRS to assist in determining the optimal downlink transmission beam combination.

[0089] Figure 5 FIG. 1 is a schematic diagram of determining a resource set based on different signal communication information during downlink channel transmission according to an embodiment of the present disclosure. Figure 5 Shown: N bf Represents the total number of antenna characteristics of the terminal, N T Indicates the number of sending channels, N R Indicates the number of receiving channels.

[0090] Among them, when the number of receiving and transmitting channels is 1T1R / 2T2R / 4T4R respectively, the number of resource sets is the total number of the entire antenna characteristics of the terminal, the number of resources is 1 SRS resource per resource set, and the number of ports is 1 / 2 / 4 respectively.

[0091] When the number of receiving and transmitting channels is 1T2R, the number of resource sets is the total number of the entire antenna characteristics of the terminal, the number of resources is 2 SRS resources per resource set, and the number of ports is 1.

[0092] When the number of receiving and transmitting channels is 2T4R, the number of resource sets is the total number of the entire antenna characteristics of the terminal, the number of resources is 2 SRS resources per resource set, and the number of ports is 2.

[0093] When the number of receiving and transmitting channels is 1T4R, the number of resource sets is the total number of the entire antenna characteristics of the terminal, the number of resources is 4 SRS resources for each resource set, and the number of ports is 1, or the number of resource sets is twice the total number of the entire antenna characteristics of the terminal, the number of resources is 2 SRS resources for each resource set, or the number of resources is 1 SRS resource for one resource set and 3 SRS resources for the other resource set, and the number of ports is 1.

[0094] The base station can use the above rules to configure resource sets for the terminal. The following will specifically describe possible implementation methods for determining the target antenna switching combination according to an embodiment of the present disclosure:

[0095] The method for determining a target antenna switching combination according to an embodiment of the present disclosure includes:

[0096] The base station determines a candidate antenna switching combination based on the information of each channel;

[0097] The base station determines a target antenna switching combination from candidate antenna switching combinations based on at least one of channel capacity and the number of data streams transmitted by the channel, wherein the target antenna switching combination is at least one combination among the candidate antenna switching combinations.

[0098] In an embodiment of the present disclosure, the base station analyzes the channel information based on each channel information and determines possible candidate antenna switching combinations based on the information. The base station evaluates the channel capacity of each candidate combination. Channel capacity can be defined as the data rate that can be transmitted within a given bandwidth. The base station also considers the number of data streams corresponding to each candidate combination. The number of data streams transmitted by a channel refers to the amount of data transmitted through a specific channel within a given time period. This amount of data can be bits, bytes, or higher-level data units, depending on the communication protocol and context used. The base station of the present disclosure can use channel state information measurement methods to determine the channel capacity and the number of data streams transmitted by the channel. Based on the above evaluation, the base station selects one or more combinations that meet specific conditions (such as high channel capacity or high number of data streams) from the candidate combinations as the target antenna switching combination.

[0099] The base station can use the information of each channel to determine the candidate antenna switching combination, and determine the target antenna switching combination based on the channel capacity of the candidate antenna switching combination and / or the number of data streams transmitted by the channel. The following is a method for the base station to determine the target antenna switching combination from the candidate antenna switching combination according to an embodiment of the present disclosure:

[0100] Based on channel transformation, time domain channel information of each channel information is obtained;

[0101] Based on the time domain channel information, determine the candidate antenna switching combination;

[0102] Determine the channel capacity of the candidate antenna switching combination and the number of data streams transmitted by the channel;

[0103] Based on at least one of the channel capacity and the number of data streams transmitted by the channel, candidate antenna switching combinations are arranged; and based on the arrangement of the candidate antenna switching combinations, a target antenna switching combination is determined.

[0104] In the disclosed embodiments, a base station obtains time-domain channel information based on channel transformation of the channel information. Channel transformation converts the received channel information from the frequency domain to the time domain using some form of channel transformation (such as Fourier transform or wavelet transform). This is because the dynamic characteristics and changes of the channel can be more accurately analyzed in the time domain. Next, the base station analyzes the channel characteristics of different antenna combinations based on the characteristics of the time-domain channel information. It determines multiple candidate antenna switching combinations that exhibit good channel characteristics in the time domain. The base station then calculates the corresponding channel capacity for each candidate antenna switching combination and counts the number of data streams corresponding to each combination. This can be determined using channel state measurements. The base station then sorts or ranks the candidate antenna switching combinations based on channel capacity and / or the number of data streams. Sorting can be based on channel capacity, the number of data streams, or a combination of both, depending on actual needs. Finally, based on the ranking results, at least one candidate antenna switching combination that meets specific criteria (such as high channel capacity or a high number of data streams) is selected as the target antenna switching combination. The target antenna switching combination should provide optimal transmission performance and reliability. For example, a schematic diagram of determining a target antenna switching combination according to an embodiment of the present disclosure is shown below. Figure 6 In the story.

[0105] Figure 6 FIG. 1 is a schematic diagram of determining a target antenna switching combination according to an embodiment of the present disclosure. Figure 6 As shown:

[0106] In the embodiment of the present disclosure, from N bf Select N from the simulation beams f The downlink channel obtained by simulating beam switching is expressed as It can be calculated by the downlink channels corresponding to different simulated beams working alone.

[0107] N bf =4, N f =2 as an example, the terminal can take There are candidate beam combinations and switching orders. The switching interval of different analog beams within the Orthogonal Frequency-Division Multiplexing (OFDM) symbol is L. s For one of the candidate beam switching modes (b2, b3), the base station measures the SRS and obtains the downlink channel of each beam in the beam group by reciprocity. And the corresponding time domain channel is obtained by fast Fourier transform (IFFT) Next, according to the beam switching interval L of the terminal s The base station combines the time domain channels of the two beams to obtain the downlink time domain channel after beam switching. The last pair Perform Fast Fourier Transform (FFT) to obtain the downlink channel in the frequency domain

[0108] Based on the above method, the base station can bf 、N f and L s , all candidate beam combinations and switching orders are traversed and calculated, and the beam combination and switching order corresponding to the downlink channel with the best performance are determined.

[0109] In the above, the base station can determine the target antenna switching combination from the candidate antenna switching combinations based on at least one of the channel capacity and the number of data streams transmitted by the channel. After the base station determines the target switching combination, it will send an indication information to the terminal, and the terminal will communicate according to the target antenna combination indicated in the indication information. The following is a detailed description of the indication information:

[0110] The indication information sent by the base station to the terminal includes multiple resource blocks, any one resource block corresponds to a resource set with one antenna characteristic, and the order of the multiple resource blocks indicates the order of antenna switching.

[0111] In the embodiment of the present disclosure, the indication information includes multiple resource blocks. The order of the resource blocks is particularly important because they indicate the order of antenna switching. This means that if the first resource block corresponds to antenna A and the second resource block corresponds to antenna B, the terminal should first use antenna A for transmission, and then switch to antenna B for transmission according to the indication of the second resource block. This mechanism allows the base station to dynamically control and manage the antenna configuration of the terminal in order to optimize the transmission performance under various channel conditions. For example, a schematic diagram of the specific indication information according to the embodiment of the present disclosure is shown below. Figure 7 Indicated in.

[0112] Figure 7 is a schematic diagram of specific instruction information according to an embodiment of the present disclosure. Figure 7 As shown:

[0113] In the embodiment of the present disclosure, the switching report (SRI) field is extended in the control information (DCI) signaling 0-1 and 0-2 of the existing resource set protocol. This is because in the mode where the terminal antenna characteristics are variable, each resource set corresponds to an antenna characteristic of the terminal, and the base station needs to determine the optimal antenna characteristic combination of the terminal by indicating multiple resource sets. Therefore, it is necessary to extend the SRS resource set indication field in the existing protocol and add SRS resource group indication (SRGI) information to indicate the resource set combination corresponding to the different antenna characteristic combinations of the terminal. Figure 7 As shown, N f The fields represent the resource sets corresponding to the different antenna characteristics of the terminal, and their order represents the switching order of the antenna characteristics. SRGI can indicate the index of the resource set order, indicating the switching order of the different antenna characteristics of the terminal, and accordingly requires bits, where N bf Indicates the total number of all antenna characteristics of the terminal.

[0114] The base station can then use the instruction information to instruct the terminal to communicate according to the target antenna switching combination. The following is an exemplary schematic diagram of communication according to an embodiment of the present disclosure:

[0115] Figure 8 Schematic diagram illustrating a communication method according to an embodiment of the present disclosure. Figure 8 As shown:

[0116] In the embodiment of the present disclosure, for uplink transmission of communication, the base station receives the handover capability parameter {N bf , N f , L s}, the base station configures 1 SRS resource set for the terminal, including N bf The terminal then uses different resources to transmit non-precoded SRS signals to the base station using different beams. The base station then determines the optimal uplink channel based on the SRS signals. Finally, the base station sends SRS resource indication information to the terminal, notifying it of the beam combination and switching order for uplink transmission. This indication information includes the optimal transmit beam combination (DCI 0-1), TRI, TPMI, and other information.

[0117] Figure 9 Schematic diagram illustrating a communication method according to an embodiment of the present disclosure. Figure 9As shown:

[0118] In the embodiment of the present disclosure, the process of downlink transmission of antenna characteristic variable MIMO based on channel reciprocity is described. The terminal will determine the number of simulated beams N that can be switched during downlink reception based on its own hardware and computing capabilities. f and the switching interval L s , and the total number of simulated beams of the terminal N bf Report to the base station together. The base station reports the terminal's parameters {N bf , N f , L s The SRS is configured using Radio Resource Control (RRC) signaling, and the Spatial Relation Info (SRI) field is used to indicate that the SRS in different resource sets are sent to the base station through different simulated beams. The base station then receives the SRS and measures each of them to obtain the uplink channels corresponding to the different beams of the terminal. Based on the mutual differences in the channels, the equivalent channels for downlink reception are obtained. The base station then switches the mode (i.e., the switching interval L) based on the antenna characteristics of the terminal. s and the number of switches N f , calculate the channel when the terminal uses variable antenna characteristics for downlink reception. Assume that the total number of simulated beams reported by the terminal is N bf , and adopt N f If there are multiple analog beams to switch, there are Candidate beam combinations and corresponding downlink channels. The base station determines the optimal downlink channel based on criteria such as capacity and rank, and notifies the terminal of the corresponding downlink channel's switching beam combination using DCI signaling. Ultimately, the terminal uses the optimal beam combination for downlink reception with variable antenna characteristics, as calculated and notified by the base station.

[0120] The base station receives any information reported by the terminal;

[0121] The base station determines the antenna switching combination for arbitrary information of the terminal based on the channel information corresponding to the characteristics of each antenna.

It should be noted that the channel information of the antenna characteristics is determined by the base station based on multiple SRS signals, and the reception of multiple SRS signals can be one or multiple times. As long as the terminal sends communication information to the base station, the base station can use the multiple SRS signals to determine the channel information corresponding to each antenna characteristic, thereby determining the antenna switching combination for the communication information.

[0123] As described above, as long as the terminal sends any information, the base station can dynamically determine the antenna switching combination of the information based on the channel information corresponding to each antenna characteristic, which can improve the reliability and efficiency of the wireless communication system and provide users with a better communication experience.

[0152] The communication method, apparatus, system, electronic device, and readable storage medium according to the embodiments of the present disclosure are described above with reference to the accompanying drawings. The base station receives multiple SRS signals from the terminal, and each SRS signal corresponds to an antenna characteristic information for one symbol period.
