[0002] In industrial applications, very high requirements are placed on 5G NR (New Radio) networks and their jitter. In 5G NR networks, base stations transmit uplink / downlink data scheduling information via the PDCCH (Physical Downlink Control Channel), and use this scheduling information to transmit and receive uplink and downlink data. The data transmission layer is one of the key pieces of information in the base station's scheduling information.

[0003] The traditional method for adjusting the number of transmission layers is based on the quality of the wireless link. The better the wireless link quality, the higher the number of transmission layers; the worse the wireless link quality, the lower the number of transmission layers.

[0004] Traditional methods for adjusting the transmission layer number based on wireless link quality suffer from adjustment lag and inaccuracy in industrial deterministic networks. In practical network applications, it has been found that due to terminal malfunctions or other reasons, even without changes to the wireless link, terminals may experience complete decoding errors within several seconds when using a higher transmission layer number. In such scenarios, the lag of the transmission layer adjustment scheme based on wireless link quality is very significant.

[0005] A new method for adjusting the number of transmission layers needs to be found to solve the problem of inaccurate adjustment of the number of transmission layers. Summary of the Invention

[0048] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this 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 this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0049] The following is combined Figures 1-6 The present invention describes a method, apparatus, electronic device, and storage medium for adjusting the number of transmission layers.

[0050] Specifically, the present invention provides a method for adjusting the number of transmission layers, referring to... Figure 1 , Figure 1 This is one of the flowcharts illustrating the transmission layer number adjustment method provided by the present invention.

[0051] The transmission layer number adjustment method provided in this embodiment of the invention includes:

[0052] S100, send an Internet Packet Explorer Ping request message to the terminal;

[0053] It should be noted that the execution entity in this embodiment is the Packet Data Convergence Protocol (PDCP) layer. The Packet Data Convergence Protocol layer belongs to the second layer of the radio interface protocol stack and is used to process radio resource management messages on the control plane and Internet protocol packets on the user plane.

[0054] Ping is an Internet packet explorer program used to test network connectivity. Ping packet latency is an important metric for evaluating packet-switched wireless communication systems.

[0055] The PDCP layer of the base station includes a Ping packet proxy module to implement the active Ping packet function, that is, to actively send Ping packets to the target terminal. The Ping packet proxy module includes: a Ping packet enabling module, a Ping request message construction and sending module, a Ping packet response detection module, and a Ping delay calculation module.

[0056] The Ping packet enabling module determines whether to enable the Ping packet function based on the configuration information of the Operation and Maintenance Center (OMC). For example, when the OMC disables the Ping packet latency detection function, the PDCP layer cannot use the Ping packet latency detection function; when the OMC enables the Ping packet latency detection function, the PDCP layer can use the Ping packet latency detection function.

[0057] When the OMC enables the Ping packet latency detection function, it constructs a Ping request message (i.e., a Ping Request message) through the Ping request message construction and sending module, and sends the constructed Ping request message to the terminal.

[0058] When sending a Ping request message, the identifier information and sending timestamp of the Ping request message are recorded. The identifier information is used to identify the Ping request message and includes at least one of address, number, and ID. The timestamp is a sequence of characters or encoded information used to record the time the Ping request message was sent.

[0059] S200, Receive Ping response message returned by the terminal;

[0060] After receiving the Ping request message sent by the PDCP layer, the terminal responds to the Ping request message and returns a Ping response message to the PDCP layer. At this time, the PDCP layer receives the Ping response message returned by the terminal through the Ping packet response detection module, which is used to receive and detect the Ping response message.

[0061] Based on the identification information of the Ping request message, the Ping response message returned by the terminal is identified to receive the Ping response message with the same identification information. For example, assuming that the identification information of the sent Ping request message is address information, such as 12a, and three Ping response messages are received, each corresponding to address information 12a, 12b, and 12c, then the Ping response message with address information 12a is selected as the required message.

[0062] It should be further noted that the Ping response detection module records the identification information and receiving timestamp of each Ping response message.

[0063] S300 determines the transmission delay based on Ping request and Ping response messages and sends the transmission delay to the Media Access Control (MAC) layer; the MAC layer adjusts the transmission layer number based on the received transmission delay.

[0064] It should be noted that the Medium Access Control (MAC) layer is used to control access to the wireless medium, detect and handle collisions, and allocate channel and communication resources.

[0065] The transmission delay is calculated by obtaining the sending timestamp of the Ping request message and the receiving timestamp of the Ping response message. The difference between these timestamps is then used as the transmission delay. For example, the transmission delay can be calculated using the Ping delay calculation module in the PDCP layer. If the sending timestamp of the Ping request message is determined to be T1 based on the Ping request message construction and sending module in the PDCP layer, and the receiving timestamp of the Ping response message is determined to be T2 based on the Ping packet response detection module in the PDCP layer, then the transmission delay is T2 - T1. This transmission delay can be understood as the Ping packet delay.

[0066] It should be further noted that the MAC layer includes a Ping packet latency result module and a Ping packet latency dynamic adjustment transmission layer module. The functions of each module are as follows:

[0067] The Ping packet latency result module is used to receive the Ping packet latency, i.e. transmission latency, sent by the PDCP layer in real time.

[0068] The Ping packet latency dynamic adjustment transmission layer module is used to adjust the data transmission layer based on the transmission latency sent by the PDCP layer. For example:

[0069] When transmission latency increases, decrease the index value of the transmission layer number;

[0070] When transmission latency decreases, increase the index value of the transmission layer;

[0071] When the transmission delay remains constant, maintain or increase the index value of the transmission layer number.

[0072] It is understandable that the index value of the transport layer number refers to the actual value of the transport layer digital segment in the air interface signaling.

[0073] The transmission layer adjustment method provided in this invention involves sending an Internet Packet Explorer Ping request message to a terminal; receiving a Ping response message returned by the terminal; determining the transmission delay based on the Ping request message and the Ping response message; and sending the transmission delay to the Media Access Control (MAC) layer. The MAC layer then adjusts the transmission layer number based on the received transmission delay. This invention adjusts the transmission layer number by adjusting the transmission delay, avoiding problems of lag and inaccuracy in transmission layer adjustment, and improving the accuracy of transmission layer adjustment. This enables 5G networks to meet the requirements for data transmission delay and bounded jitter in deterministic industrial control networks.

[0074] Based on the above embodiments, the present invention also provides a method for adjusting the number of transmission layers, referring to... Figure 2 , Figure 2 This is the second flowchart of the transmission layer adjustment method provided by the present invention.

[0075] The transmission layer number adjustment method provided in this embodiment of the invention includes:

[0076] S400, receive the transmission delay sent by the packet data aggregation protocol layer;

[0077] It should be noted that the execution entity in this embodiment is the MAC layer, which has a Ping packet latency result module for receiving the transmission latency sent by the PDCP layer.

[0078] S500 adjusts the number of transmission layers based on transmission latency.

[0079] The MAC layer includes a module for dynamically adjusting the transmission layer number based on the Ping packet delay. This module adjusts the data transmission layer number according to the transmission delay sent by the PDCP layer. For example:

[0080] When transmission latency increases, decrease the index value of the transmission layer number;

[0081] When transmission latency decreases, increase the index value of the transmission layer;

[0082] When the transmission delay remains constant, maintain or increase the index value of the transmission layer number.

[0083] The transmission layer number adjustment method provided in this invention receives the transmission delay sent by the packet data aggregation protocol layer and adjusts the transmission layer number based on the transmission delay. This invention adjusts the transmission layer number by controlling the transmission delay, avoiding problems of lag and inaccuracy in transmission layer number adjustment, and improving the accuracy of transmission layer number adjustment. This enables 5G networks to meet the requirements of deterministic industrial control networks for data transmission delay and bounded jitter.

[0084] Based on the above embodiments, adjusting the number of transmission layers based on transmission delay includes: reducing the number of transmission layers when the transmission delay is greater than a first transmission delay; increasing the number of transmission layers when the transmission delay is less than a second transmission delay; and maintaining or increasing the number of transmission layers when the transmission delay is consistent with the adjacent delay of the transmission delay.

[0085] It should be noted that the first and second transmission delay values ​​are preset based on the transmission demand information, and the two transmission delay values ​​are not the same. The adjacent transmission delay refers to the transmission delay obtained in the last calculation, which can also be understood as the transmission delay that is closest to the currently calculated transmission delay.

[0086] When the MAC layer receives the transmission delay sent by the PDCP layer, it compares the transmission delay with the preset transmission delay, and then adjusts the number of transmission layers based on the comparison result.

[0087] It should be further explained that the adjustment of the number of transmission layers is based on the initial value of the number of transmission layers. The methods for setting the initial value of the number of transmission layers include: (1) The MAC layer sets the initial value of the number of transmission layers according to the quality of the wireless link. The higher the quality of the wireless link, the larger the initial value of the number of transmission layers. For example, when the quality of the wireless link is high, the initial value of the number of transmission layers is set to 3; when the quality of the wireless link is low, the initial value of the number of transmission layers is set to 2; (2) The initial value of the number of transmission layers is configured through the OMC.

[0088] It should be further noted that when adjusting the number of transport layers, it is also necessary to determine the adjustment range of the transport layer index value. For example, the adjustment range of the transport layer index value can be configured through OMC. In this way, when adjusting the number of transport layers, the preset adjustment range value can be used as a reference.

[0089] For example, when the OMC is configured to increase the number of transport layers, the transmission delay value detected by the corresponding PDCP layer is the first delay value, such as t_Layer_Inc_Delay.

[0090] When the number of transport layers configured in the OMC is reduced, the transmission delay value detected by the corresponding PDCP layer is the second delay value, for example, the second delay value is t_Layer_Dec_Delay.

[0091] When configuring the transport layer number increase in OMC, the adjustment value of the transport layer number index value for each increase is the first adjustment value, for example, the first adjustment value is Layer_Inc_Delta;

[0092] When the number of transport layers is reduced in the OMC configuration, the adjustment value of the transport layer index value for each reduction is the second adjustment value, for example, the second adjustment value is Layer_Dec_Delta.

[0093] After receiving the transmission delay information from the PDCP layer, the MAC layer adjusts the number of transmission layers, including:

[0094] When the transmission delay is greater than the first transmission delay (t_Layer_Inc_Delay), the index value of the transmission layer is reduced by the first adjustment value (Layer_Inc_Delay), such as by 1;

[0095] When the transmission delay is less than the second transmission delay (t_Layer_Dec_delay), the index value of the transmission layer number is increased by the second adjustment value (Layer_Dec_delay), such as by 1;

[0096] If the transmission delay is consistent with the adjacent transmission delay, the index value of the transmission layer remains unchanged.

[0097] The embodiments of the present invention first determine the initial value of the number of transmission layers, thus accurately defining the initial range of the number of transmission layers, and then fine-tuning the number of transmission layers based on the transmission delay, thereby improving the accuracy of adjusting the number of transmission layers.

[0098] Based on the above embodiments, adjusting the number of transmission layers based on transmission delay further includes: reducing the number of transmission layers when the transmission delay is greater than the average of historical transmission delays; and increasing the number of transmission layers when the transmission delay is less than the average of historical transmission delays.

[0099] It should be noted that historical transmission delay refers to the transmission delay calculated previously. The average historical transmission delay can be the average of the transmission delay values ​​of the previous N consecutive statistics, where N is greater than or equal to 1.

[0100] When the transmission delay is greater than the average of the historical transmission delay, the number of transmission layers is reduced. For example, when the transmission delay is greater than the average of the transmission delay values ​​of the previous N consecutive statistics, the index value of the number of transmission layers is reduced by 1.

[0101] When the transmission delay is less than the average of the historical transmission delays, the number of transmission layers is increased. For example, when the transmission delay is less than the average of the transmission delay values ​​of the previous N consecutive statistics, the index value of the number of transmission layers is incremented by 1.

[0102] When the transmission delay is consistent with the average historical transmission delay or with the adjacent transmission delay, the number of transmission layers is maintained or increased. For example, the index value of the transmission layer is kept unchanged or the index value of the transmission layer is incremented by 1.

[0103] This invention compares the transmission delay with the pre-saved average of historical transmission delays and adjusts the number of transmission layers based on the comparison result, thus achieving real-time adjustment of the number of transmission layers according to the transmission delay. By setting the average of historical transmission delays, real-time adjustment of the number of transmission layers is convenient and the accuracy of the adjustment is improved.

[0104] like Figure 3 As shown, Figure 3 This is a flowchart illustrating the adjustment of the transmission layer number based on transmission delay according to the present invention. The base station includes a packet data aggregation protocol layer and a media access control layer.

[0105] The packet data aggregation protocol layer sends a Ping request message to the terminal. At the same time as sending the Ping request message, the packet data aggregation protocol layer records the identification information and sending timestamp of the Ping request message.

[0106] The terminal returns a Ping response message to the base station.

[0107] The packet data aggregation protocol layer receives the Ping response message returned by the terminal. Simultaneously, the packet data aggregation protocol layer records the reception timestamp of the Ping response message, detects the identification information of the Ping response message, and matches it with Ping request messages containing the same identification information.

[0108] The packet data aggregation protocol layer calculates the air interface transmission delay, i.e., the transmission delay, based on the difference between the sending timestamp of the Ping request message and the receiving timestamp of the Ping response message, which have the same identification information, and sends the transmission delay to the media access control layer.

[0109] The media access control layer receives the transmission delay and adjusts the number of transmission layers based on the received transmission delay, including: decreasing the index value of the number of transmission layers when the transmission delay increases; increasing the index value of the number of transmission layers when the transmission delay decreases; and maintaining or increasing the index value of the number of transmission layers when the transmission delay remains unchanged.

[0110] The media access control layer sends data to the terminal according to the new transport layer number.

[0111] In this embodiment of the invention, the Packet Data Convergence Protocol (PDCP) layer sends an Internet Packet Explorer (IPC) Ping request message to the terminal; the PDC layer receives a Ping response message returned by the terminal; based on the Ping request message and the Ping response message, the PDC layer determines the transmission delay and sends the transmission delay to the Media Access Control (Media Access Control) layer; the Media Access Control (Media Access Control) layer receives the transmission delay sent by the PDC layer; and based on the transmission delay, the number of transmission layers is adjusted. Adjusting the number of transmission layers by controlling the transmission delay avoids problems of lag and inaccuracy in transmission layer adjustment, improving the accuracy of transmission layer adjustment, so that the 5G network can meet the requirements of data transmission delay and bounded jitter in deterministic networks for industrial control.
