[0002] Ultra-Reliable Low-Latency Communications (URLLC) is a key technology in 5G (the fifth-generation mobile communication technology). URLLC provides low-latency data transmission for fields such as autonomous driving. In these technologies, base stations allocate dedicated channels for URLLC services, and data transmission occurs through these channels. However, the channels used for data transmission can be susceptible to external interference, leading to higher latency.

[0003] It is evident that the relevant technologies suffer from high data transmission latency. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1 , Figure 1 This is a flowchart of a data transmission method applied to a network-side device according to an embodiment of the present invention, such as... Figure 1 As shown, it includes the following steps:

[0029] Step 101: Split the data packets of each service in the multiple services into a first data packet and a second data packet.

[0030] The aforementioned services can be URLLC services or other services requiring low-latency data transmission. Data packets for these services are transmitted from network-side equipment to the receiving equipment via a channel. The network-side equipment can be server equipment, base stations, or other similar devices, while the receiving equipment can be user equipment (UE), a terminal, or a personal mobile device.

[0031] In one embodiment, each of the multiple services corresponds to a separate receiving device. That is, for each receiving device, one data packet of a service is transmitted; when transmitting data packets of a service to N receiving devices, N data packets of each service are transmitted separately. Here, N is a positive integer greater than 1. In this way, by assigning each service to a separate receiving device, it is convenient to subsequently transmit the split first and second data packets through the channels of different devices.

[0032] The first data packet and the second data packet mentioned above are obtained by splitting the data packet of each service. The size of the first data packet and the size of the second data packet can be the same or different. By splitting the data packet of each service, it is possible to transmit a data packet of a service split through two channels, with each channel transmitting two split data packets.

[0033] Step 102: Allocate the channel corresponding to each service.

[0034] It should be noted that, since each of the multiple services corresponds to a receiving device, a corresponding channel is allocated to each service, and this channel corresponds one-to-one with the service and the receiving device.

[0035] Step 103: Transmit the first data packet of the first service and the second data packet of the second service based on the channel corresponding to the first service, and transmit the first data packet of the second service and the second data packet of the first service based on the channel corresponding to the second service, wherein the first service and the second service are different services among the plurality of services.

[0036] The first service and the second service mentioned above are different services among multiple services. The first data packet of the first service and the second data packet of the second service are transmitted through the channel of the first service, and the first data packet of the second service and the second data packet of the first service are transmitted through the channel of the second service. In this way, the data packets of the same service can be transmitted through two channels. If one channel is interfered with, the data packet transmission of the other channel will not be affected, which reduces the impact of interference on transmission delay, thereby reducing data transmission delay and improving data transmission reliability.

[0037] It should be noted that the data packets of the first service and the data packets of the second service are transmitted simultaneously. If the transmission of the data packets of the first service is completed, but the transmission of the data packets of the second service is not completed, the data packets of the second service can continue to be transmitted using both the channel of the first service and the channel of the second service, or the channel of the second service and other service channels can be used simultaneously to transmit the data packets of the second service and other service data packets. For example, the first data packet of the second service and the second data packets of other services can be transmitted through the channel of the second service, and the first data packet of other services and the second data packet of the second service can be transmitted through the channel of other services.

[0038] In this embodiment of the invention, data packets for each of multiple services are split into a first data packet and a second data packet; a channel is allocated for each service; the first data packet of the first service and the second data packet of the second service are transmitted based on the channel corresponding to the first service, and the first data packet of the second service and the second data packet of the first service are transmitted based on the channel corresponding to the second service, wherein the first service and the second service are different services among the multiple services. In this way, data packets for the same service can be transmitted through two channels, and the transmission of data packets on the other channel is unaffected even if one channel is interfered with, reducing the impact of interference on transmission delay, thereby reducing data transmission delay and improving data transmission reliability.

[0039] In one embodiment, before splitting the data packet of each of the multiple services into a first data packet and a second data packet, the method further includes:

[0040] Obtain the first communication rate requirement parameter corresponding to the data packet of the first service, and the second communication rate requirement parameter corresponding to the data packet of the second service;

[0041] Based on the first communication rate requirement parameter and the second communication rate requirement parameter, the first splitting information corresponding to the first service and the second splitting information corresponding to the second service are calculated.

[0042] The step of splitting the data packets of each of the multiple services into a first data packet and a second data packet includes:

[0043] Based on the first splitting information, the data packets of the first service are split to obtain the first data packet and the second data packet of the first service;

[0044] Based on the second splitting information, the data packets of the second service are split to obtain the first data packet and the second data packet of the second service.

[0045] The aforementioned first communication rate requirement parameter characterizes the data transmission rate that should be met when transmitting data packets for the first service, and the aforementioned second communication rate requirement parameter characterizes the data transmission rate that should be met when transmitting data packets for the second service. It should be noted that, under the condition of meeting the first and second communication rate requirement parameters, the service data packets can achieve low-latency transmission. However, for a service data packet (e.g., a data packet for the first service), after splitting the first service data packet into a first data packet and a second data packet, it needs to be transmitted through two channels separately. The transmission conditions of the first and second data packets differ between the two channels; for example, one channel may have better transmission conditions than the other. In this case, to minimize the data packet transmission latency, it is necessary to maximize the data packet size transmitted through the channel with better transmission conditions and minimize the data packet size transmitted through the channel with poorer transmission conditions.

[0046] Therefore, in this embodiment of the invention, based on the first communication rate requirement parameter and the second communication rate requirement parameter, the first splitting information corresponding to the first service and the second splitting information corresponding to the second service are calculated. By splitting the data packets using the calculated first splitting information and the second splitting information, the transmission of the split first data packet and the second data packet can meet the communication rate requirement parameter, thereby achieving low-latency data transmission.

[0047] The first splitting information and the second splitting information are parameters used to split data packets. They can be splitting ratios or splitting instructions. By splitting the data packets of the first service based on the first splitting information, the first data packet and the second data packet of the first service are obtained; by splitting the data packets of the second service based on the second splitting information, the first data packet and the second data packet of the second service are obtained.

[0048] In one embodiment, calculating the first splitting information corresponding to the first service and the second splitting information corresponding to the second service based on the first communication rate requirement parameter and the second communication rate requirement parameter includes:

[0049] Based on the first initial ratio and the second initial ratio, as well as the first communication rate requirement parameter and the second communication rate requirement parameter, a first power, a second power, a third power and a fourth power are calculated. The first power is the power of transmitting the first data packet of the first service based on the channel of the first service. The second power is the power of transmitting the second data packet of the second service based on the channel of the first service. The third power is the power of transmitting the first data packet of the second service based on the channel of the second service. The fourth power is the power of transmitting the second data packet of the first service based on the channel of the second service.

[0050] Calculate the total power, which is the sum of the first power, the second power, the third power, and the fourth power;

[0051] Adjust the first initial ratio and the second initial ratio until the total power meets the preset conditions, generate the first split information based on the adjusted first initial ratio, and generate the second split information based on the adjusted second initial ratio.

[0052] The aforementioned first initial ratio is the ratio for splitting data packets of the first service, and the aforementioned second initial ratio is the ratio for splitting data packets of the second service. It should be noted that after splitting the data packets using the first and second initial ratios, there are four split data packets (the first and second data packets of the first service, and the first and second data packets of the second service). The power of transmitting these four split data packets through the channels of the first and second services is respectively the first power, the second power, the third power, and the fourth power. In this invention, the first and second initial ratios are adjusted by the total power so that, under the condition of satisfying the first and second communication rate requirements, the total power also meets the preset conditions, thereby obtaining the optimal first and second splitting information.

[0053] In some implementations, the communication rate requirement parameters corresponding to the four split data packets can be calculated using a first initial ratio and a second initial ratio, respectively. Then, the first power, second power, third power, and fourth power can be calculated using these corresponding communication rate requirement parameters. For example, after calculating the communication rate requirement parameters corresponding to the four split data packets, the first power, second power, third power, and fourth power can be obtained by multiplying them by preset coefficients.

[0054] In this embodiment of the invention, a first power, a second power, a third power, and a fourth power are calculated based on a first initial ratio and a second initial ratio, as well as a first communication rate requirement parameter and a second communication rate requirement parameter. The first power is the power for transmitting a first data packet of the first service via a first service channel; the second power is the power for transmitting a second data packet of the second service via a first service channel; the third power is the power for transmitting a first data packet of the second service via a second service channel; and the fourth power is the power for transmitting a second data packet of the first service via a second service channel. A total power is calculated, which is the sum of the first power, the second power, the third power, and the fourth power. The first and second initial ratios are adjusted until the total power meets a preset condition. First splitting information is generated based on the adjusted first initial ratio, and second splitting information is generated based on the adjusted second initial ratio. Thus, by adjusting the first and second initial ratios using the total power, the total power also meets the preset condition while satisfying the first and second communication rate requirement parameters, thereby obtaining optimal first and second splitting information.

[0055] In one embodiment, the preset condition includes one of the following:

[0056] The total power is the minimum power after multiple adjustments;

[0057] The total power is matched with the preset power.

[0058] In this embodiment of the invention, the preset conditions can be set according to the data transmission requirements of the base station. Specifically, if it is necessary to minimize resource consumption during data transmission, the preset condition can be set to the total power being the adjusted minimum power; if it is necessary to maximize the data transmission rate, the preset condition can be set to match the total power with a preset power.

[0059] Here, we assume the maximum transmission power of the base station is P. max The maximum sum rate that can be provided is R. max This can proportionally increase the communication rate requirements of both services. k Assuming it is raised to γ' k At this time, the total power P' max The total data transmission rate is R' max Therefore, the following conclusion holds true:

[0060]

[0061] As can be seen from the above formula, when the total power reaches the maximum transmission power (i.e., the preset power), the total data transmission rate reaches its maximum value, and the data transmission delay is the lowest at this time.

[0062] In one embodiment, calculating the first power, second power, third power, and fourth power based on the first initial ratio and the second initial ratio, as well as the first communication rate requirement parameter and the second communication rate requirement parameter, includes:

[0063] Calculate the first coefficient, which is the product of the first exponent and the second exponent. The first exponent is the exponent of the first preset coefficient and the first product. The first product is the product of the first difference and the second communication rate requirement parameter. The first difference is the difference between the second preset coefficient and the second initial ratio. The second exponent is the exponent of the first preset coefficient and the second product. The second product is the product of the first initial ratio and the first communication rate requirement parameter.

[0064] Calculate the second coefficient, which is the exponent of the product of the first preset coefficient and the third product. The third product is the product of the second difference and the first communication rate requirement parameter. The second difference is the difference between the second preset coefficient and the first initial ratio.

[0065] Calculate the third coefficient, which is the product of the third exponent and the fourth exponent. The third exponent is the exponent of the first preset coefficient and the third product. The fourth exponent is the exponent of the first preset coefficient and the fourth product. The fourth product is the product of the second initial ratio and the second communication rate requirement parameter.

[0066] Calculate the fourth coefficient, which is the exponent of the product of the first preset coefficient and the first coefficient;

[0067] Calculate the first power, the second power, the third power, and the fourth power. The first power is the quotient of the fifth product and the first fading factor. The fifth product is the product of the first coefficient and the noise power. The second power is the quotient of the sixth product and the second fading factor. The sixth product is the product of the second coefficient and the noise power. The third power is the quotient of the seventh product and the third fading factor. The seventh product is the product of the third coefficient and the noise power. The fourth power is the quotient of the eighth product and the fourth fading factor. The eighth product is the product of the fourth coefficient and the noise power.

[0068] In this embodiment of the invention, a first coefficient, a second coefficient, a third coefficient, and a fourth coefficient are calculated using a first initial ratio and a second initial ratio, as well as a first communication rate requirement parameter and a second communication rate requirement parameter. Then, a first power, a second power, a third power, and a fourth power can be calculated using the first coefficient, the second coefficient, the third coefficient, and the fourth coefficient, respectively.

[0069] It should be noted that the first power, second power, third power, and fourth power, which can be calculated using the first, second, third, and fourth coefficients respectively, can be derived as follows:

[0070] For example, a base station provides services to multiple receiving devices. The base station has M antennas, and the multiple receiving devices have N antennas, where M and N are positive integers greater than 1. The base station configures an independent channel for each service, and each channel includes a sub-channel for transmitting a first data packet and a sub-channel for transmitting a second data packet. Let represent a subchannel, where k represents a service (k∈{1,2}, k=1 represents the first service, k=2 represents the second service), and b represents a subchannel (b∈{1,2}, b=1 represents the subchannel for transmitting the first data packet, b=2 represents the subchannel for transmitting the second data packet); through g k，b Represents the fading factor, for example, g 1,1 This represents the calculation of the first fading coefficient corresponding to the first power, g 1,2 This represents the calculation of the second fading coefficient corresponding to the second power, g 2,1 This represents the calculation of the third fading coefficient corresponding to the third power, g 2,2 This indicates the calculation of the fourth fading coefficient corresponding to the second power.

[0071] For the data packet L of the k-th service k Its communication rate requirement parameter is γ k The first data packet after splitting is L k，1 The second data packet is L k,2 The split ratio is denoted as α. k At this point, the communication requirement rate R of the first data packet after splitting is... k,1 The communication requirement rate R of the second data packet k,2 They are respectively:

[0072]

[0073] The transmission power of the first data packet is P. k,1 The transmission power of the second data packet is P. k,2 For the channel of the k-th service, it is necessary not only to transmit the first data packet L of this service. k,1 It also needs to transmit the second data packet L of another service (denoted as the j-th service). j,2 When transmitting via channel decoding, the first data packet is decoded first, followed by the second data packet. Assuming the noise power is N0, the communication requirement rate for the first data packet and the communication requirement rate for the second data packet can be calculated using the following formula:

[0074]

[0075] The formulas for calculating the first power, second power, third power, and fourth power can be obtained from the above formulas:

[0076]

[0077] Wherein, the first power is P 1,1 The second power is P 1,2 The third power is P 2,1 The fourth power is P 2,2 .

[0078] Furthermore, let's set up an optimization problem, where the preset condition is that the total power is minimized. The optimization problem is... This can be expressed by the following formula:

[0079]

[0080] subject to 0≤α k ≤1, k=1,2;

[0081]

[0082] However, a mathematical solution can yield multiple answers, such as... Figure 2 As shown, there are 9 possible solutions (Solutions 1 to 9). However, the first and second splitting ratios need to satisfy condition α. k Since ∈[0,1], the solution range needs to be limited to the range of solution 9 or the edge of solution 9 when solving.

[0083] Specifically, there are nine possible solutions to the above optimization problem:

[0084] Solution 1: α1 = 1, α2 = 1;

[0085] Solution 2: α1 = 1, α2 = 1;

[0086] Solution 3: α1 = 0, α2 = 0;

[0087] Solution 4: α1 = 0, α2 = 1;

[0088] Solution 5:

[0089] Solution 6:

[0090] Solution 7:

[0091] Solution 8:

[0092] Solution 9:

[0093] The coefficient Ω is specifically:

[0094]

[0095] That is, solutions 1 to 8 are actually special calculation results of solution 9. For example, solution 1 can be understood as follows: the gain of the first data packet of the first service transmitted through the channel of the first service is greater than the gain of the second data packet of the second service; the gain of the first data packet of the second service transmitted through the channel of the second service is greater than the gain of the second data packet of the first service; and the gain of the first data packet of the first service transmitted through the channel of the first service is the same as the gain of the first data packet of the second service transmitted through the channel of the second service. Therefore, solution 9 can be directly used as the adjusted first and second initial ratios to generate the first and second ratio information.

[0096] Furthermore, after generating the first proportional information and the second proportional information, the current total power can be calculated as follows:

[0097]

[0098] It should be noted that, since the relationship between the base station's transmit power and transmission rate has already been explained above, this formula can be used to proportionally increase the communication rate requirements of the two channels, thereby increasing the service transmission rate until the maximum transmission rate is reached. This will not be elaborated further here.

[0099] In some implementations, the optimization problem The solution process can be represented as follows:

[0100] First, optimize the problem. It can be represented as:

[0101]

[0102] The optimization problem described above is a convex optimization problem, which can be solved using the Karush-Kuhn-Tucker Conditions (KKT). Its Lagrangian function can be expressed as:

[0103]

[0104] Furthermore:

[0105] Formula 1:

[0106] Formula 2:

[0107] In the formula, λ1, λ2, η1, and η2 are intermediate coefficients. For formula one, if λ1 ≠ 0, then α1 = 1 and η2 = 0. Based on this, analyzing formula two yields:

[0108] If λ2≠0 and η2=0, then α2=1;

[0109] If λ² = 0 and η² ≠ 0, then α² = 0;

[0110] If λ2≠0 and η2≠0, then α2 has no solution;

[0111] If λ² = 0 and η² = 0, then

[0112] For Formula 2, if λ1=0 and η1≠0, then α1=0. Based on this, analyzing Formula 2 yields:

[0113] If λ2≠0 and η2=0, then α2=1;

[0114] If λ² = 0 and η² ≠ 0, then α² = 0;

[0115] If λ² = 0 and η² = 0, then

[0116] For Formula 2, if λ1 = 0, η1 = 0. Based on this, analyzing Formula 2 yields:

[0117] If λ²≠0 and η²=0, then α²=1.

[0118] If λ² = 0 and η² ≠ 0, then α² = 0.

[0119] If λ² = 0 and η² = 0, then we have:

[0120]

[0121] Simplifying, we get: Pick Then there is The adjusted first and second initial ratios are then calculated as follows:

[0122]

[0123] Thus, through the above calculation process, solutions 1 to 9 are obtained.

[0124] In one embodiment, transmitting the first data packet of the first service and the second data packet of the second service based on the channel corresponding to the first service, and transmitting the first data packet of the second service and the second data packet of the first service based on the channel corresponding to the second service, includes:

[0125] When the number of the plurality of services is even, the first data packet of the first service and the second data packet of the second service are transmitted based on the channel corresponding to the first service, and the first data packet of the second service and the second data packet of the first service are transmitted based on the channel corresponding to the second service.

[0126] In one embodiment, the method further includes:

[0127] When the number of the multiple services is odd, the multiple services are divided into a first part and a second part. The number of services included in the first part is even, and the second part includes three services.

[0128] For each of the multiple services included in the first part, the first data packet of the third service and the second data packet of the fourth service are transmitted based on the channel corresponding to the third service, and the first data packet of the fourth service and the second data packet of the third service are transmitted based on the channel corresponding to the fourth service, wherein the third service and the second service are different services among the multiple services included in the first part;

[0129] Regarding the second part, the first data packet of the fifth service and the second data packet of the sixth service are transmitted based on the channel corresponding to the fifth service, the first data packet of the sixth service and the second data packet of the seventh service are transmitted based on the channel corresponding to the sixth service, and the first data packet of the seventh service and the second data packet of the fifth service are transmitted based on the channel corresponding to the seventh service. The fifth service, the sixth service and the seventh service are the three services included in the second part.

[0130] It should be noted that, to improve transmission stability, a service's data packet needs to be split into a first data packet and a second data packet, and transmitted through two channels; however, a single channel can transmit at most one first data packet and one second data packet. Therefore, when transmitting service data packets, the data packets of two services can be transmitted to each other. That is, the first data packet of the first service and the second data packet of the second service are transmitted through the channel corresponding to the first service, and the first data packet of the second service and the second data packet of the first service are transmitted through the channel corresponding to the second service.

[0131] However, in actual transmission, there are situations where data packets from two services cannot be transmitted to each other, specifically when the number of services is odd. In such cases, it is not possible to divide the services into pairs and use them as the first and second services for mutual transmission. Therefore, it is necessary to design a method for mutual transmission of three services to improve transmission stability.

[0132] In this embodiment of the invention, when the number of multiple services is odd, the multiple services are divided into a first part and a second part. The number of services included in the first part is even, and the second part includes three services. At this time, the services in the first part can be divided into two groups to be used as the first service and the second service (or the third service and the fourth service) for mutual transmission, while the three services in the second part are transmitted to each other to improve the stability of transmission.

[0133] Specifically, regarding the second part, the first data packet of the fifth service and the second data packet of the sixth service are transmitted based on the channel corresponding to the fifth service; the first data packet of the sixth service and the second data packet of the seventh service are transmitted based on the channel corresponding to the sixth service; and the first data packet of the seventh service and the second data packet of the fifth service are transmitted based on the channel corresponding to the seventh service. In this way, the first and second data packets of each of the three services are transmitted through different channels, and each channel of the three services transmits only one first data packet and one second data packet. Even if one channel is interfered with, the data packet transmission of the other channels is not affected, reducing the impact of interference on transmission delay, thereby reducing data transmission latency and improving data transmission reliability.

[0134] Please see Figure 3 , Figure 3 This is a structural diagram of a data transmission device provided in an embodiment of the present invention, as shown below. Figure 3 As shown, the data transmission device 300 includes:
