Description
Technical Field
[0001] The present application relates to the field of wireless communication technology, and in particular to a load determination method, device, system, storage medium, and computer program product. Background Art
[0002] With the rapid development of wireless communication technology, wireless communication networks are becoming increasingly widespread. With the increasing number of wireless communication device users, increasing communication system capacity has become a pressing technical challenge. One currently proposed method is to use multiple-input, multiple-output (MIMO) antennas to increase communication system capacity. To improve RF energy efficiency and extend battery life, new RF architectures have been proposed, such as small-pitch MIMO, reconfigurable intelligent surfaces (RIS), and full-range MIMO antennas on continuous surfaces. These new RF architectures all share a common feature: the use of tunable components such as PIN diodes and varactor diodes as loads. In antenna design, these antennas are referred to as load-modulated (LM) antennas. In a load-modulated antenna, a portion of the modulated transmit signal needs to be converted into a control signal for the tunable component, such as a bias voltage, to adjust the load value. This allows the antenna current or radiation field to be altered by adjusting the load at the antenna end to transmit different signals.
[0003] Currently, in order to stimulate the current or radiation field corresponding to the Orthogonal Frequency Division Multiplexing (OFDM) symbol, it is necessary to quickly and accurately determine the load value. However, for load-modulated antennas, especially for closely spaced coupled antenna arrays, the load value cannot be obtained using a closed-form solution. Instead, the load value must be optimized for each transmitted OFDM symbol, resulting in high computational overhead at the transmitter and a significant amount of time and resources required to optimize the load value, resulting in low efficiency for load-modulated antennas.

[0063] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.
[0064] The embodiment of the present application provides a load determination method, referring to Figure 1 As shown, the method is applied to a transmitting node, and the method includes the following steps:
[0065] Step 101: Receive a channel quality parameter value and a first quantization bit number reported by a receiving end node.
[0066] The first quantization bit number is determined by the receiving end node based on a pre-configured signal-load dictionary set.
[0067] In an embodiment of the present application, the transmitting node is an end node that provides signal services, such as a base station or a base station using a novel load antenna. The receiving node is generally a user terminal device, such as an intelligent mobile terminal device, including a smartphone and a smart car, or an intelligent terminal device capable of intelligent communication. The channel quality parameter value is obtained by the receiving node measuring the communication channel between the receiving node and the transmitting node, and the first quantization bit number is determined by the receiving node based on a pre-configured signal-load dictionary set. The transmitting node receives the channel quality parameter value and the first quantization bit number reported by the receiving node.
[0068] Step 102: Determine a target signal-load dictionary that matches the signal quality parameter value and the first quantization bit number from a pre-configured signal-load dictionary set.
[0069] In this embodiment of the present application, a signal-load dictionary set is preconfigured in both the receiving node and the transmitting node. This allows the receiving node and the transmitting node to perform subsequent unified processing operations based on the same signal-load dictionary set. A matching target signal-load dictionary is determined from the signal-load dictionary set based on the signal quality parameter value and the first number of quantization bits.
[0070] Step 103: Determine the target load corresponding to the signal to be transmitted based on the target signal-load dictionary.
[0071] In the embodiment of the present application, a target load that meets the requirements for transmitting the signal to be transmitted is determined from the target signal-load dictionary.
[0072] Step 104: Load the target load onto the signal transmitting device of the transmitting end node to stimulate the transmission of the signal to be transmitted.
[0073] In an embodiment of the present application, the signal transmitting device is a device for transmitting signals in a transmitting end node. According to the working parameters of the signal transmitting device of the transmitting end node based on the target load, the signal to be transmitted is transmitted based on the target load. In this way, the transmitting end node determines the signal-load dictionary based on the parameters reported by the receiving end node, and quickly determines the corresponding load from the determined signal-load dictionary to perform signal transmission, thereby reducing the computing resource consumption of determining the load and improving the efficiency of determining the load.
[0074] The load determination method provided in an embodiment of the present application, after receiving the channel quality parameter and the first quantization bit number reported by the receiving node by the transmitting node, determines a target signal-load dictionary that matches the signal quality parameter value and the first quantization bit number from a pre-configured signal-load dictionary set, and based on the target signal-load dictionary, determines the target load corresponding to the signal to be transmitted, and then loads the target load value onto the signal transmitting device of the transmitting node to stimulate the transmission of the signal to be transmitted. In this way, the transmitting node selects a matching signal-load dictionary based on the signal quality parameter value and the first quantization bit number fed back by the receiving node, and selects the corresponding load value from the determined signal-load dictionary to stimulate the transmission of the signal to be transmitted. This effectively reduces the overhead generated in the process of selecting signals and searching and generating antenna loads while meeting the bit error rate requirements, solves the problem of low efficiency in determining load values in the application of load modulation antennas, and proposes a load determination method that realizes a solution for quickly determining the load value of the load modulation antenna, effectively reduces the computational overhead of the transmitting end, shortens the time and resource consumption when optimizing the load value, and improves the working efficiency of the load modulation antenna.
[0075] Based on the above embodiments, the embodiments of the present application provide a load determination method, which is applied to a receiving node, referring to Figure 2 As shown, the method includes the following steps:
[0076] Step 201: Measure the channel quality of the communication channel between the transmitting node and the transmitting node to obtain a channel quality parameter value and a channel quality indicator CQI value.
[0077] In an embodiment of the present application, after a communication channel is established between a receiving node and a transmitting node, the receiving node measures the channel quality of the communication channel according to a preset measurement period, and can obtain a channel quality parameter and a channel quality indicator (CQI) value of the signal.
[0078] Step 202: Determine a first number of quantization bits that matches a channel quality parameter value and a channel quality indicator CQI value from a pre-configured signal-load dictionary set.
[0079] In the embodiment of the present application, a quantization bit number that matches both the channel quality parameter value and the CQI value is searched from a pre-configured signal-load dictionary set to obtain a first quantization bit number.
[0080] Step 203: Report the channel quality parameter value and the first quantization bit number to the transmitting end node.
[0081] In an embodiment of the present application, the receiving node reports the detected channel quality parameter value and the determined first quantization bit number to the transmitting node, so that the transmitting node determines the load based on the channel quality parameter and the first quantization bit number fed back by the receiving node.
[0082] The load determination method provided in an embodiment of the present application measures the channel quality of the communication channel between the receiving node and the transmitting node, obtains a channel quality parameter value and a channel quality indicator CQI value, and then determines a first quantization bit number that matches the channel quality parameter value and the channel quality indicator CQI value from a pre-configured signal-load dictionary set, and reports the channel quality parameter value and the first quantization bit number to the transmitting node. In this way, the transmitting node selects a matching signal-load dictionary based on the signal quality parameter value and the first quantization bit number fed back by the receiving node, and selects a corresponding load value from the determined signal-load dictionary to stimulate the transmission of the signal to be transmitted. This effectively reduces the overhead generated in the process of selecting the signal and searching and generating the antenna load while meeting the bit error rate requirements, solves the problem of low efficiency in determining the load value during the application of load modulation antennas, and proposes a load determination method that realizes a solution for quickly determining the load value of the load modulation antenna, effectively reduces the computational overhead of the transmitting end, shortens the time resource consumption when optimizing the load value, and improves the working efficiency of the load modulation antenna.
[0083] Based on the above embodiments, the present application provides a load determination method, referring to Figure 3 As shown, the method includes the following steps:
[0084] Step 301: The receiving end node measures the channel quality of the communication channel between the receiving end node and the transmitting end node, and obtains a channel quality parameter value and a channel quality indicator CQI value.
[0085] In an embodiment of the present application, the receiving end node is a user terminal (User Equipment, UE) and the transmitting end node is a new load modulation antenna base station (referred to as base station) as an example. After the UE accesses the new load modulation antenna base station, the UE periodically measures the channel quality of the communication channel between the UE and the base station according to the instruction of the new load modulation antenna base station, and obtains the corresponding channel quality parameter value and CQI value.
[0086] Step 302: The receiving end node determines a first number of quantization bits that matches a channel quality parameter value and a channel quality indicator CQI value from a pre-configured signal-load dictionary set.
[0087] In an embodiment of the present application, the UE searches for the first quantization bit number that matches the channel instruction value and the CQI value from a locally pre-configured signal-load dictionary set. The signal-load dictionary is usually determined by the digital modulation method and the number of quantization bits. Each digital modulation method is combined with the quantization bit value to obtain a corresponding signal-load dictionary. Among them, the digital modulation method can be, for example, Quadrature Phase Shift Keying (QPSK), 16-bit Quadrature Amplitude Modulation (QAM), 64QAM, etc., and the value of the quantization bit value can be, for example, 2, 4, 6, 8, 12, 16, etc.
[0088] Step 303: The receiving node reports the channel quality parameter value and the first quantization bit number to the transmitting node.
[0089] In an embodiment of the present application, the UE reports the channel quality parameter value and the first quantization bit number to the base station through the communication channel.
[0090] Step 304: The transmitting node receives the channel quality parameter value and the first quantization bit number reported by the receiving node.
[0091] The first quantization bit number is determined by the receiving end node based on a pre-configured signal-load dictionary set.
[0092] In an embodiment of the present application, a base station receives a channel quality parameter value and a first number of quantization bits reported by a UE.
[0093] Step 305: The transmitting end node determines a target signal-load dictionary that matches the signal quality parameter value and the first quantization bit number from a pre-configured signal-load dictionary set.
[0094] In this embodiment of the present application, the signal-load dictionary set preconfigured by the transmitting node is the same as the signal-load dictionary set preconfigured by the receiving node. The transmitting node may send its own configured signal-load dictionary set to the receiving node. The base station searches the configured signal-load dictionary set for a target signal-load dictionary that matches both the signal quality parameter value and the first number of quantization bits.
[0095] Step 306: The transmitting node determines the target load corresponding to the signal to be transmitted based on the target signal-load dictionary.
[0096] In the embodiment of the present application, the base station searches the target signal-load dictionary for a target load that meets the requirements for transmitting the signal to be transmitted.
[0097] Step 307: The transmitting node loads the target load onto the signal transmitting device of the transmitting node to stimulate the transmission of the signal to be transmitted.
[0098] In an embodiment of the present application, the UE adjusts the load of the transmitting antenna to a target load, and then transmits the signal to be transmitted through the transmitting antenna.
[0099] Based on the above embodiment, in other embodiments of the present application, step 305 can be implemented by steps 305a to 305c:
[0100] Step 305a: The transmitting node determines a first computing capability parameter and a bit error rate of the transmitting node.
[0101] In an embodiment of the present application, the first computing capability parameter may be the remaining available resources of the central processing unit (CPU) of the transmitting node. The bit error rate is a maximum bit error requirement set by the transmitting node for signal transmission. The transmitting node quantitatively analyzes its own computing performance to determine its first computing capability parameter and a pre-configured bit error rate.
[0102] Step 305b: The transmitting node determines the first modulation mode and the second quantization bit number based on the signal quality parameter, the first quantization bit number, the first computing capability parameter, and the bit error rate.
[0103] In an embodiment of the present application, the transmitting node determines a first modulation mode and a second quantization bit number based on a received signal quality parameter and a first quantization bit number, as well as its own first computing capability parameter and a pre-configured bit error rate. The first modulation mode refers to a digital modulation mode used to modulate the transmitted signal, such as QPSK, and the second quantization bit number may be, for example, K.
[0104] Step 305c: The transmitting node determines a target signal-payload dictionary that matches the first modulation mode and the second number of quantization bits from the signal-payload dictionary set.
[0105] In an embodiment of the present application, the transmitting node determines a target signal-payload dictionary that matches both the first modulation mode and the second quantization bit number from a pre-configured signal-payload dictionary set.
[0106] Based on the above embodiments, in other embodiments of the present application, refer to Figure 4 As shown, the transmitting node is further configured to perform step 308:
[0107] Step 308: The transmitting node transmits the first modulation mode and the second quantization bit number to the receiving node using a preset transmission mode.
[0108] The preset sending mode is the downlink control information DCI signaling mode.
[0109] In an embodiment of the present application, the transmitting node generates DCI information in a downlink control information (DCI) signaling manner based on the first modulation mode and the second quantization bit number, and then sends the DCI information including the first modulation mode and the second quantization bit number to the receiving node.
[0110] It should be noted that step 308 may be performed by the transmitting node after performing step 305b.
[0111] Correspondingly, the receiving node executes step 309:
[0112] Step 309: The receiving node receives the first modulation mode and the second quantization bit number sent by the transmitting node.
[0113] In an embodiment of the present application, after the receiving node receives the DCI information including the first modulation mode and the second quantization bit number sent by the transmitting node, the receiving node parses and identifies the DCI information to obtain the first modulation mode and the second quantization bit number.
[0114] In other embodiments of this application, refer to Figure 5 As shown, after the receiving node executes step 309, it is further configured to execute steps 310 to 312:
[0115] Step 310: The receiving node receives the signal to be transmitted transmitted by the transmitting node.
[0116] Step 311: The receiving end node determines a target signal-payload dictionary that matches the first modulation mode and the second quantization bit number from the signal-payload dictionary set.
[0117] In an embodiment of the present application, after the receiving node receives the signal to be transmitted transmitted by the transmitting node, the receiving node determines and obtains the target signal-load dictionary from the signal-load dictionary set based on the first modulation mode and the second quantization bit number sent by the transmitting node.
[0118] Step 312: The receiving node demodulates the signal to be transmitted using the target signal-payload dictionary to obtain a demodulated signal.
[0119] In an embodiment of the present application, the receiving node determines the corresponding data modulation method based on the determined target signal-load dictionary to demodulate the received signal to be transmitted to obtain a final demodulated signal.
[0120] Based on the above embodiment, in other embodiments of the present application, step 306 can be implemented by steps 306a to 306b:
[0121] Step 306a: The transmitting node searches the target signal-load dictionary for a reference quantized signal having the smallest signal value error with the signal to be transmitted.
[0122] In an embodiment of the present application, the transmitting node calculates the signal value error between the signal included in the target signal-load dictionary and the signal to be transmitted, and determines the signal with the smallest signal value error to obtain a reference quantized signal.
[0123] Step 306b: The transmitting node determines the target load as the load corresponding to the reference quantized signal from the target signal-load dictionary.
[0124] In an embodiment of the present application, the transmitting node determines that in the target signal load dictionary, the load corresponding to the reference quantized signal is the target load.
[0125] Based on the above embodiments, in other embodiments of the present application, refer to Figure 6 As shown, before the transmitting node executes step 304, it is further configured to execute step 313:
[0126] Step 313: The transmitting node receives the signal-load dictionary set sent by the dictionary set providing node.
[0127] In the embodiments of the present application, the dictionary set providing node can be an upper-layer core network, or a transmitting node that has another signal-load dictionary set. A pre-configured signal-load dictionary set is provided by the dictionary set providing node sending the signal-load dictionary set to the transmitting node. Upon receiving the signal-load dictionary set, the transmitting node stores it in its corresponding storage area.
[0128] Based on the above embodiments, in other embodiments of the present application, refer to Figure 6 As shown, the transmitting node is further configured to perform step 314:
[0129] Step 314: The transmitting node sends the signal-load dictionary set to the receiving node.
[0130] In an embodiment of the present application, the transmitting node sends the signal-load dictionary set stored in itself to the receiving node, thereby unifying the signal-load dictionary set between the receiving node and the transmitting node, and ensuring the reliability and accuracy of subsequent data processing.
[0131] It should be noted that step 314 may be executed before step 301 .
[0132] Based on the above embodiment, in other embodiments of the present application, step 302 can be implemented by steps 302a to 302b:
[0133] Step 302a: The receiving node determines a second modulation mode that matches the channel quality parameter value from the signal-load dictionary set.
[0134] In an embodiment of the present application, the receiving node determines a matching second modulation mode from a signal-load dictionary set according to a channel quality parameter value.
[0135] Step 302b: The receiving node obtains a first number of quantization bits by matching from a signal-load dictionary set based on the second modulation mode, the CQI value, and the second computing capability parameter of the receiving node.
[0136] In an embodiment of the present application, the receiving node can determine one or more quantization bit numbers based on the second modulation mode and the CQI value. When there are multiple quantization bit numbers, an optimal first quantization bit number can be determined from the multiple quantization bit numbers based on the second computing capability parameter. For example, the first quantization bit number can be determined from the multiple quantization bit numbers based on the level of the second computing capability.
[0137] Based on the aforementioned embodiments, the present application provides a load determination method applicable to a MIMO-OFDM communication method using a load-modulated antenna. The general implementation process can be as follows: the transmitter load modulates the antenna based on the number of quantized bits of the OFDM signal fed back by the receiver, selects a suitable signal-load dictionary, and uses the load value in the signal-load dictionary to generate a transmitted OFDM signal. This reduces the overhead of selecting the signal and antenna load search and generation while meeting the bit error rate requirements. One corresponding application scenario is a new type of load-modulated antenna as a base station, and the UE uses a conventional MIMO antenna architecture. The corresponding specific implementation process can be shown as follows:
[0138] Step a11: The upper layer network notifies the current base station of the available signal-load dictionary set through pre-configuration or other base stations through Radio Resource Control (RRC) signaling.
[0139] The signal-load dictionary is determined by the digital modulation scheme (such as QPSK, 16QAM, or 64QAM) and the number of quantization bits, K (such as 2, 4, 6, 8, 12, or 16). Each combination of digital modulation scheme and K value corresponds to a signal-load dictionary. The upper layer network can directly notify the UE connected to the current base station of the available signal-load dictionary set. The signal-load dictionary set for UEs connected to the current base station can also be sent by the current base station.
[0140] For example, the signal-load dictionary determined by the combination of the digital modulation mode and the K value may be as shown in Table 1 below, where the available signal-load dictionary is represented by √:

[0145] The digital modulation mode is determined by the channel quality indicator (CQI). The K value is related to the digital modulation mode and the channel quality equivalent signal-to-noise ratio (SNR). For example, see Table 2 above. The higher the digital modulation mode order, the larger the K value that can be selected. The worse the channel quality, the larger the K value that can be selected.
[0146] Step a12: After the UE accesses the base station, the base station transmits a Channel State Information-Reference Signal (CSI-RS) reference signal.
[0147] Step a13: The UE measures the channel quality and evaluates the bit error rate (BLER). Based on the BLER, the UE determines a channel quality indicator (CQI) value. The UE then selects a quantization bit number (K) within a K range based on the channel quality and the digital modulation scheme corresponding to the CQI value.
[0148] The UE may measure the channel quality by measuring the signal-to-noise ratio (SNR), the signal-to-interference-noise ratio (SINR), the signal-to-noise-and-distortion ratio (SNDR), etc. The channel quality corresponds to the aforementioned channel quality parameter values.
[0149] For example, when the channel quality equivalent SNR measured by the UE is -2 decibels (dB), the corresponding CQI value can be determined to be 3 and the digital modulation mode can be QPSK according to Table 2. If the K value is determined to be 4 and 6 according to Table 1, the UE determines the CPU available resources that the UE can use for communication at this time. If the CPU available resources of the UE exceed a preset threshold, for example, 50%, the K value is determined to be 6, otherwise the K value is determined to be 4. It is assumed that in this embodiment, based on the CPU available resources of the UE, the K value is finally determined to be 4.
[0150] Step a14: The UE reports the CQI value and the K value to the current base station.
[0151] Exemplarily, the UE reports CQI=3, K=4 to the current base station.
[0152] Step a15: The current base station makes a judgment based on the CQI value and K value reported by the UE and the base station status, selects the digital modulation mode and the quantization bit number K value, and determines the signal-load dictionary used for the transmitted signal.
[0153] Exemplarily, the current base station makes a judgment based on the CQI value 3 reported by the UE and the recommended K value 4, combined with the base station status, to select the digital modulation mode and the quantization bit number K value to determine the signal-load dictionary used for the transmitted signal. A specific implementation method may be: calculating the average value of the N CQIs received in the period closest to the current moment, and using the average value as the statistical CQI value, where N is a natural number, which can usually be pre-configured and determined by the base station; if the K value received at the current moment falls within the K value range corresponding to the statistical CQI value, then the K value received at the moment is determined to determine the signal-load dictionary used for the transmitted signal; if the K value received at the current moment exceeds the K value range corresponding to the statistical CQI value, the average value of the most recent N+1 K values reported by the UE (including the K value received at the current moment) can be calculated, and then the current base station uses the K value closest to the average value to determine the signal-load dictionary used for the transmitted signal. Based on this method, it is assumed that the modulation mode finally determined by the current base station is QPSK and the quantization bit number K is 6, that is, the OFDM signal is transmitted using the QPSK, K=6 signal-load dictionary.
[0154] Step a16: The current base station sends the selected digital modulation mode and quantization bit number K value to the UE via DCI signaling.
[0155] Exemplarily, the current base station sends QPSK and K=6 to the UE through DCI signaling.
[0156] Step a17: The UE receives DCI signaling to obtain the digital modulation mode and the quantization bit number K value, and determines the signal-payload dictionary used for transmitting the signal.
[0157] For example, after receiving the DCI signaling sent by the current base station, the UE parses the DCI signaling and determines that the digital modulation mode is QPSK and K=6, so that the QPSK signal-payload dictionary with K=6 can be determined for transmission.
[0158] The signal-load dictionary determined by the UE in step a17 corresponds to the aforementioned target signal-load dictionary.
[0159] Step a18: When the current base station transmits each OFDM signal, it selects the quantized signal with the smallest error from the selected signal-load dictionary, obtains the corresponding load and loads it on the antenna to stimulate the transmission signal.
[0160] Each OFDM signal is a signal to be transmitted.
[0161] Exemplarily, the current base station uses a QPSK, K=6 signal-load dictionary to transmit signals, where there are 64 elements in the dictionary, each element contains a digitally modulated OFDM quantized signal Sk and its corresponding load value Lk, where k=1, 2,..., 64. In this way, a total of 64 load values can be used to generate a column of digitally modulated OFDM signals. When the OFDM signal to be sent is s, the current base station searches among the 64 elements in the QPSK, K=6 signal-load dictionary, selects the sk that minimizes the error |s-sk|, and then uses the load lk corresponding to sk as the antenna load to excite sk.
[0162] Step a19: The UE receives the transmitted signal and demodulates the received transmitted signal using the quantized signal matched in the signal-payload dictionary.
[0163] Exemplarily, when the UE receives the transmission signal sk, it performs maximum-likelihood detection using QPSK and a signal-payload dictionary with K=6.
[0164] It should be noted that, for the description of the same steps and contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.
[0165] The load determination method provided in an embodiment of the present application measures the channel quality of the communication channel between the receiving end node and the transmitting end node to obtain a channel quality parameter value and a channel quality indicator CQI value. The receiving end node determines a first quantization bit number that matches the channel quality parameter value and the channel quality indicator CQI value from a pre-configured signal-load dictionary set, and reports the channel quality parameter value and the first quantization bit number to the transmitting end node. After receiving the channel quality parameter and the first quantization bit number reported by the receiving end node, the transmitting end node determines a target signal-load dictionary that matches the signal quality parameter value and the first quantization bit number from the pre-configured signal-load dictionary set, and determines a target load corresponding to the signal to be transmitted based on the target signal-load dictionary. The target load value is then loaded onto the signal transmitting device of the transmitting end node to stimulate the transmission of the signal to be transmitted. In this way, the transmitting node selects a matching signal-load dictionary based on the signal quality parameter value and the first quantization bit number fed back by the receiving node, and selects a corresponding load value from the determined signal-load dictionary to stimulate the transmission of the signal to be transmitted. This effectively reduces the overhead generated in the process of selecting the signal and searching and generating the antenna load while meeting the bit error rate requirements, solves the problem of low efficiency in determining the load value during the application of the load modulation antenna, proposes a load determination method, realizes an implementation scheme for quickly determining the load value of the load modulation antenna, effectively reduces the calculation overhead of the transmitting end, shortens the time resource consumption when optimizing the load value, and improves the working efficiency of the load modulation antenna.
