Description

Technical Field

[0001] The present invention relates to the field of semiconductors, and in particular to a data transmission method, device, readable storage medium and electronic equipment. Background Art

[0002] LTE is a wireless data communication technology standard. In the LTE system, in order to adapt to unknown or changing channel conditions, the 3GPP protocol provides a transmit diversity mode, that is, using the Alamouti format for coding processing to achieve space-frequency diversity to improve the reliability of data transmission. Then, when receiving on the UE side, the space domain and frequency domain are balanced according to the corresponding precoding format.

[0003] Usually, during data transmission, the equalization processing methods on the UE side are: Method 1, single-transmitter multiple-receiver equalization processing method, which directly performs equalization processing on the equivalent receiving model, so this method does not lose information; Method 2, dual-stream multiple-receiver equalization processing method, which first averages the equivalent channel model and then performs single-stream processing on the average result, so this method has low computational complexity and can reduce residual noise in the channel estimation result.

[0004] However, the calculation complexity of the above method 1 is relatively high. When the signal-to-noise ratio of the channel itself is poor, it is easy to cause the accuracy of the channel estimation result to be low. Therefore, the method 1 is suitable for large frequency selection scenarios but not for low signal-to-noise ratio scenarios. On the contrary, in large frequency selection scenarios, the above method 2 is easy to cause the error platform to rise. Therefore, the method 2 is suitable for low signal-to-noise ratio scenarios. It can be seen that the data transmission method provided by the prior art has poor flexibility and cannot meet the needs of multiple scenarios.

[0005] With respect to the problem that the data transmission method provided by the above-mentioned prior art has poor flexibility, no effective solution has been proposed so far. Summary of the invention

[0050] In the prior art, the transmit data is usually encoded based on the Alamouti format based on the transmit diversity mode provided by the 3GPP protocol to achieve space-frequency diversity. Then, when the UE receives data, it first performs spatial and frequency domain equalization based on the precoding format. Specifically, for example, assuming that the 36.211 protocol has two transmit antenna ports, the precoding process for the data can be shown in the following formula (1):

[0051]

[0052] In the above formula (1), d(·) represents a modulated complex symbol to be sent; Re(·) and Im(·) represent the real part and imaginary part of the acquired complex number respectively; x p (k) represents the transmission symbol mapped on the kth RE of the pth antenna port. The complex form of the transmission symbol can be shown as the following formula (2):

[0053]

[0054] In the above formula (2), [·] * represents the complex conjugate.

[0055] Furthermore, in the prior art, channel equalization is usually combined with precoding and decoding to achieve baseband reception. Specifically, for example, in a single antenna reception scenario, after data is transmitted through the channel, the baseband equivalent received signal received by the UE side receiver can be as shown in the following formula (3):

[0056] y in =H in x P +n formula (3)

[0057] In the above formula (3), y in H is the received signal after noise whitening (including noise power normalization) obtained by the channel estimation module, and its dimension is 1×1; in =[H in,0 H in,1 ] is the channel estimation result after noise whitening (including noise power normalization) obtained by the channel estimation module, and its dimension is 1×2; n is additive white Gaussian noise, and its dimension is 1×1. It should also be noted here that due to the whitening process, the above n satisfies the following formula (4):

[0058]

[0059] Based on the above formula (4), the above formula (3) is expanded, and the expansion results can be shown as the following formulas (5) and (6):

[0060]

[0061]

[0062] By combining the above formulas (5) and (6), we can obtain the signal model shown in the following formula (7):

[0063]

[0064] It can be seen from the above formula (7) that by splicing two REs, a 2T2R signal model is obtained, and the equivalent channel of the signal model can be shown as the following formula (8):

[0065]

[0066] The above single antenna receiving model is extended to the multi-antenna receiving model scenario. Specifically, assuming that the receiving antenna dimension is N R Based on the models shown in formulas (1) to (8) above, the model of each receiving dimension can be derived. Furthermore, by stacking the models of each receiving dimension according to the order of antennas, the received signal and channel estimation results shown in the following formulas (9) and (10) can be obtained:

[0067]

[0068]

[0069] In the above formula (10), The following formula (11) is satisfied:

[0070]

[0071] In the above formula (11), represents the equivalent matrix of the rth receiving dimension, where r∈{0,1,2,…,N R -1}. Furthermore, the equivalent channel model in the multi-antenna reception scenario can be shown as the following formula (12):

[0072]

[0073] In the above formula (12), The following formula (13) is satisfied:

[0074]

[0075] In the above formula (12), The following formula (14) is satisfied:

[0076]

[0077] In the above formula (14), the above n r (k) represents the whitened additive noise on the kth RE in the rth receiving dimension.

[0078] In the prior art, based on the equivalent transmission model in the above-mentioned single antenna reception model scenario and the equivalent transmission model in the above-mentioned multi-antenna reception model scenario, the equivalent transmission model is usually equalized using the following equalization method 1 and equalization method 2:

[0079] Equalization method 1: directly equalize the above equivalent receiving model. Specifically, the equivalent receiving model is equivalent to a 2-transmit 2N R The received model is equalized using the MIMO equalization method. Further, the equalization result is demodulated to obtain the soft information of two equivalent transmission streams, and then the soft information of the two equivalent transmission streams is synthesized into a real transmission stream for further data processing.

[0080] It should also be noted that a synthesized single real transmission stream can be determined based on the equalization processing result before demodulation processing. In addition, when the influence of inter-stream interference is not considered, a single data stream receiving processing method can be directly adopted to reduce the computational complexity.

[0081] Equalization method 2: Perform average equalization between REs on the above equivalent receiving model. Specifically, assuming that the channels on a pair of two subcarriers constituting transmit diversity precoding are close and their frequency domain responses differ slightly, when performing equalization, the equivalent channel matrix is ​​firstly By averaging among REs, we can obtain the equivalent channel matrix shown in the following formula (15):

[0082]

[0083] In the above formula (15), The following formula (16) is satisfied:

[0084]

[0085] Next, the equivalent channel matrix shown in the above formula (16) is stacked according to the antenna order, and the averaged equivalent channel matrix shown in the following formula (17) can be obtained:

[0086]

[0087] Based on the equivalent channel matrix shown in the above formula (17), its covariance can be calculated as shown in the following formula (18):

[0088]

[0089] In the above formula (18), the above Δ satisfies the following formula (19):

[0090]

[0091] It can be understood that the averaged equivalent channel matrix shown in the above formula (17) satisfies the diagonal matrix form. When performing equalization processing, the averaged equivalent channel model can be processed as a single stream to reduce interference between streams.

[0092] However, based on the above balancing method 1, the system dimension is 1×N R , and the dimension of equalization processing is 2×2N R , which results in a high computational complexity in the equalization process, and when the signal-to-noise ratio of the channel itself is poor, it is easy to cause the accuracy of the channel estimation result to be low and the data transmission performance to be poor. In addition, based on the above-mentioned equalization method 2, since the phase rotation of the channel frequency domain amplitude will occur during the RE averaging process, it is easy to cause the error platform to rise in the scenario with a large frequency selection, and in the scenario with a high transmission rate requirement (i.e., using a high code rate and high-order modulation), it is easy to increase the performance loss of data transmission.

[0093] Based on the above-mentioned problems existing in the above-mentioned equalization method 1 and the above-mentioned equalization method 2 in the prior art, according to an embodiment of the present invention, a method embodiment of data transmission is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.

Figure 1 As shown above Figure 1 The illustrated embodiment may include at least the following implementation steps, which may be the technical solution implemented by steps S11 to S13.

[0095] Step S11, based on at least one of a first parameter set, a second parameter set, and a third parameter set corresponding to the data to be transmitted, a target receiving equalization mode is selected from multiple candidate receiving equalization modes, wherein the data to be transmitted is data transmitted using a transmit diversity technology, the first parameter set is used to characterize the channel characteristics of the baseband transmission channel corresponding to the data to be transmitted, the second parameter set is used to characterize the channel estimation result of the previous stage transmission channel corresponding to the data to be transmitted, and the third parameter set is used to characterize the transmission mode corresponding to the data to be transmitted;

Specifically, for example, in a certain data transmission process, the target receiving equalization mode is determined to be SIMO based on the first parameter set. For another example, in another data transmission process, based on the first parameter and the third parameter, the target receiving equalization mode is determined to be MIMO.

It can be understood that the transmission parameters can be used to characterize data transmission characteristics.

[0101] In the solution provided by the present invention, after the receiving end determines the target receiving equalization mode, the data to be transmitted is equalized based on the target receiving equalization mode. Specifically, for example, in a low signal-to-noise ratio scenario, the target receiving equalization mode is determined to be a MIMO mode based on the first parameter set, the second parameter set, and the third parameter set, and then, based on the MIMO mode, the equivalent channel matrix is ​​first averaged between REs, and then the averaged equivalent channel model is processed by single stream, thereby reducing the computational complexity and reducing the residual signal-to-noise ratio of the channel.

[0102] In an embodiment of the present invention, firstly, based on at least one of a first parameter set, a second parameter set and a third parameter set corresponding to the data to be transmitted, a target reception equalization mode is selected from multiple candidate reception equalization modes, wherein the data to be transmitted is data transmitted using a transmit diversity technology, the first parameter set is used to characterize the channel characteristics of a baseband transmission channel corresponding to the data to be transmitted, the second parameter set is used to characterize the channel estimation result of a previous transmission channel corresponding to the data to be transmitted, and the third parameter set is used to characterize the transmission mode corresponding to the data to be transmitted, and then, the data to be transmitted is transmitted according to the target reception equalization mode, and data is transmitted by selecting the target reception equalization mode from multiple candidate reception equalization modes based on multiple parameter sets corresponding to the data to be transmitted, thereby achieving the purpose of flexibly selecting the target reception equalization mode during data transmission to improve the adaptability of the data transmission method, thereby achieving the technical effect of improving the flexibility and adaptability of the data transmission method, and then solving the technical problem that the data transmission method provided by the related technology has poor flexibility.

[0119] Step S1213: Transmit the data to be transmitted using the first target transmission model.

[0120] In the optional schemes provided in the above steps S1211 to S1213, the above-mentioned first method can be a single-transmit multiple-receive equalization method; the above-mentioned preset average model can be an inter-RE average model corresponding to the first method; the above-mentioned second calculation result can be used to determine whether to perform element-by-element average calculation on the equivalent channel matrix corresponding to the data to be transmitted; the above-mentioned initial transmission model can be an initial channel model under a preset data transmission scenario; the above-mentioned first target transmission model can be a channel model obtained after equalization processing of the initial transmission model based on the first method.

[0121] The following combination Figure 2 The above method is further explained. Figure 2 is a schematic diagram of an optional data transmission process according to an embodiment of the present invention, such as Figure 2 As shown, during the data transmission process, the space-frequency data is first converted into an initial equivalent channel model (that is, the equivalent channel matrix is ​​determined), and then, before performing channel equalization processing, based on the above selector function, it is determined whether to perform element averaging calculation on the equivalent channel matrix.

[0122] Still Figure 2 As shown, specifically, for example, assuming that the binarization result of the above selector function is True, it is necessary to perform element-wise average calculation on the equivalent channel matrix, so when it is necessary to perform element-wise average calculation on the equivalent channel matrix, a single-stream multi-receive equalization method is used to perform equalization processing on it for further data transmission.

[0123] In an optional embodiment, in step S12, the target reception equalization mode is the second mode, and transmitting the data to be transmitted according to the target reception equalization mode includes:

[0124] Step S1221, in response to the second mode, performing dual-stream multi-receive equalization processing on the initial transmission model to obtain a second target transmission model;

[0127] Still Figure 2As shown, specifically, for example, assuming that the binarization result of the above selector function is False, there is no need to perform element average calculation on the equivalent channel matrix. Therefore, after the equalization method judgment is completed using the selector function, the dual-stream multi-receive equalization method is used to perform equalization processing on the equivalent channel matrix for further data transmission.

[0128] In the optional embodiments provided by the above steps S1211 to S1213 and steps S1221 to S1222, the technical effect that can be achieved is: based on the target reception equalization method determined by the first parameter set, the second parameter set and the third parameter set corresponding to the data to be transmitted, the initial transmission model is correspondingly equalized, thereby improving the flexibility and adaptability of the data transmission method and being able to meet the needs of multiple scenarios.

[0129] In an optional embodiment, in step S11, selecting a target receiving equalization mode from a plurality of candidate receiving equalization modes based on at least one of the first parameter set, the second parameter set, and the third parameter set includes:

[0130] Step S1121, in response to the first parameter set satisfying the first condition, the second parameter set satisfying the second condition and the third parameter set satisfying at least one of the third conditions, the second mode is selected as the target reception equalization mode; wherein the first condition includes: the delay spread of the baseband transmission channel is higher than the first threshold, and / or the transmitting antenna dimension of the baseband transmission channel satisfies the preset transmit diversity mode; the second condition includes: the residual signal-to-noise ratio of the previous stage transmission channel is higher than the second threshold; the third condition includes: the coding rate corresponding to the data to be transmitted is higher than the third threshold, and / or the signal modulation mode corresponding to the data to be transmitted is one of the preset modulation modes.

[0131] In the optional scheme provided in the above step S1121, it is assumed that the above first parameter set is the delay spread of the baseband transmission channel, the above preset transmit diversity mode is the transmit antenna dimension of 2, the above second parameter set is the residual signal-to-noise ratio of the previous stage transmission channel, the above third parameter set is the coding rate and modulation mode, the above first threshold is 3 microseconds, the above second threshold is 10 decibels, the above third threshold is 0.7, and the above preset modulation mode is 64QAM (or 256QAM). Under this condition, when the delay spread of the baseband transmission channel is greater than 3 microseconds, the transmit antenna dimension of the baseband transmission channel is 2 and the receive antenna dimension is 3, the residual signal-to-noise ratio of the previous stage transmission channel is higher than 10 decibels, the coding rate corresponding to the data to be transmitted is higher than 0.7, and the signal modulation mode corresponding to the data to be transmitted is 256QAM, the above selector function R o The output binarization result is False. At this time, it is determined that the target receiving equalization mode is the dual-stream multi-receiving equalization processing mode.

[0132] In an optional embodiment, in step S11, selecting a target receiving equalization mode from a plurality of candidate receiving equalization modes based on at least one of the first parameter set, the second parameter set, and the third parameter set includes:

[0133] Step S1131, in response to at least one of multiple situations, select the first mode as the target reception equalization mode, wherein the multiple situations include: the first parameter set does not meet the first condition, the second parameter set does not meet the second condition and the third parameter set does not meet the third condition; the first condition includes: the delay spread of the baseband transmission signal is higher than the first threshold, and / or the transmitting antenna dimension of the baseband transmission signal meets the preset transmit diversity mode; the second condition includes: the residual signal-to-noise ratio of the previous stage transmission channel is higher than the second threshold; the third condition includes: the coding rate corresponding to the data to be transmitted is higher than the third threshold, and / or the signal modulation mode corresponding to the data to be transmitted is one of the preset modulation modes.

[0134] In the optional scheme provided in the above step S1131, it is assumed that the above first parameter set is the delay spread of the baseband transmission channel, the above preset transmit diversity mode is the transmit antenna dimension of 1, the above second parameter set is the residual signal-to-noise ratio of the previous stage transmission channel, the above third parameter set is the coding rate and modulation mode, the above first threshold is 3 microseconds, the above second threshold is 10 decibels, the above third threshold is 0.7, and the above preset modulation mode is 64QAM (or 256QAM). Under this condition, when the delay spread of the baseband transmission channel is less than 3 microseconds, the transmit antenna dimension of the baseband transmission channel is 1 and the receive antenna dimension is 3, the residual signal-to-noise ratio of the previous stage transmission channel is lower than 10 decibels, the coding rate corresponding to the data to be transmitted is lower than 0.7, and the signal modulation mode corresponding to the data to be transmitted is 64QAM, the above selector function R o The output binarization result is True. At this time, the target receiving equalization mode is determined to be the single-stream multi-receiving equalization processing mode.

[0135] The following combination Figure 3 An optional implementation manner provided by the present invention is further described. Figure 3 is a schematic diagram of an optional average noise reduction performance comparison in a data transmission process according to an embodiment of the present invention, Figure 3 The data transmission scenario shown is: the transmitting antenna dimension of the baseband transmission channel is 2, the receiving antenna dimension is 1, the data transmission channel is a Rayleigh channel, and the amplitude of the channel response of the same receiving antenna constituting the two REs in a pair of transmit diversity precoding particles is the same, and the phase difference is configured to be 0 degree, 5 degree, and 10 degree respectively, and the noise is additive white Gaussian noise, the modulation mode is 256QAM, and the residual noise variance in the channel estimation result is approximately 0.1 of the variance before denoising.

[0136] In the above Figure 3In the data transmission scenario shown in FIG. 1 , the average noise reduction performance is compared during the data transmission diversity processing. Figure 3 As shown, in the low signal-to-noise ratio scenario, the performance of the average noise reduction of the startup channel is improved. When there is a phase difference between the two paired REs, the average noise reduction process of the startup channel introduces phase ambiguity, which causes the performance to present an error platform effect, and then causes the MSE after equalization to not decrease with the increase of the signal-to-noise ratio. If the data transmission method provided by the present invention is not adopted, the reliability of the high-code rate transmission process will be poor. In contrast, the data transmission method with good flexibility provided by the present invention can not only retain the average noise reduction capability of the startup channel, but also avoid the error platform in the high signal-to-noise ratio scenario, so that there will be no performance loss in a variety of transmission scenarios and channel conditions.
