DETAILED DESCRIPTION

[0085] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

These terms are only used to distinguish the same type of information from each other. Optionally, without departing from the scope of the present application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

[0087] It should be understood that the terms "comprises" and "includes" indicate the presence of the previously mentioned features, steps, operations, but do not exclude the presence, occurrence or addition of one or at least one other feature, step, operation. The terms "and / or" and the like used in this application may be interpreted as inclusive, or mean any one or any combination. Optionally, "A and / or B" means "any of the following: A; B; A and B". In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship.

[0088] As Bluetooth technology continues to develop, the business scenarios of Bluetooth transmission are becoming more and more diverse, including True Wireless Stereo (TWS) headphones, low-power audio, and spatial audio.

[0089] In related technologies, terminal devices can transmit multiple services in a multi-service scenario by reusing antennas, increasing the number of Bluetooth links or the amount of data carried by each link. In a multi-service scenario, multiple service data are usually transmitted in order of priority.

[0090] Next, combine Figure 1 , explaining the transmission process of multiple business data in existing multi-business scenarios.

[0091] Figure 1 This is a schematic diagram of an application scenario provided by the embodiment of this application. Figure 1 , Figure 1 It may be a scheduling process for transmitting and receiving antennas to transmit multiple service data. The multiple service data may include BLE audio service data, object push profile (OPP), mobile hotspot (Wireless Fidelity, WiFi) service data, BLE scanning service data, etc.

[0092] Among them, the BLE audio service has a higher priority and a large amount of data. It can be transmitted through at least two links (left and right ears) at the same time, and has regular sending and receiving intervals, such as trigger point 1, trigger point 2, and trigger point 3, etc.

[0093] OPP is transmitted through an asynchronous connectionless link (ACL), and the priority of ACL is low.

[0094] In each transmission cycle, after transmitting the higher priority BLE audio service data, the OPP and BLE scanning service data with lower priority are transmitted. The latency and throughput of OPP transmission also depend on the number of low priority services and the time-sharing ratio between them.

[0095] At the same time, in each cycle, there may also be time division multiplexing of receiving antenna resources by WiFi services.

[0096] During the above transmission process, the transmission delay and throughput of protocol data including object push configuration files in multiple business scenarios cannot be effectively guaranteed, resulting in low reliability of information transmission.

[0097] In order to solve the above technical problems, the embodiment of the present application provides a data transmission method, which determines the initial transmission window corresponding to the protocol data in the transmission cycle, determines whether there is business data to be transmitted in the initial transmission window, and if so, updates the initial transmission window according to the transmission period of the business data to obtain at least one target transmission window, and transmits the protocol data in at least one target transmission window. If not, transmit the protocol data in the initial transmission window. In this way, in a complex scenario where multiple services coexist, the priority of the protocol data in the Bluetooth service transmission is improved, and the initial transmission window is dynamically adjusted according to the business data, which ensures the timeliness and throughput of the protocol data transmission and improves the reliability of information transmission.

[0098] The technical solution shown in the present application is described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other, and the same or similar contents will not be described repeatedly in different embodiments.

[0099] Figure 2 A flowchart of a data transmission method provided by an embodiment of the present application. The execution subject of the embodiment of the present application can be a terminal device or a processor in the terminal device. The terminal device can include a Bluetooth component. Figure 2 , the method comprising:

[0100] S201. Determine an initial transmission window corresponding to protocol data in a transmission cycle.

[0101] The transmission cycle may be a cycle formed with the start time of the protocol data as a trigger point and at intervals of a preset time under an ideal condition.

[0102] Next, combine Figure 3 , an example is given to illustrate the transmission cycle.

[0103] Figure 3 A schematic diagram of a transmission cycle provided in an embodiment of the present application. Figure 3 , Figure 3 It includes multiple transmission cycles, each of which includes trigger points, such as trigger point 1, trigger point 2, trigger point 3 and trigger point 4. The trigger point is the starting time of transmitting the protocol data in the initial transmission window under ideal conditions. Under ideal conditions, the data in the initial transmission window can be transmitted first in each transmission cycle.

[0104] The protocol data may include data such as object push configuration files, which are not limited here.

[0105] The start time of the initial transmission window coincides with the start time of the transmission period.

[0106] The initial transmission window can be dynamically determined according to the amount of protocol data.

[0107] For example, the initial transmission window may occupy 6 time slots according to the data volume of the protocol data, or may occupy 4 time slots according to the data volume of the protocol data.

[0108] Next, combine Figure 4 , an example is given for the initial transmission window.

[0109] Figure 4 A schematic diagram of another transmission cycle provided in an embodiment of the present application. Figure 4 , Figure 4 It can include 3 transmission cycles. Under ideal conditions, assuming that each transmission cycle is 100 time slots, the initial transmission window occupies 6 time slots, and the starting time of the initial transmission window coincides with the starting time of the transmission cycle. The 6 time slots in the initial transmission window include sending time slots and receiving time slots. The sending time slots and receiving time slots are arranged at intervals. The sending time slots can be used to send protocol data, and the receiving time slots can be used to receive response data sent by the opposite end. The response data is used to indicate that the opposite end has received the protocol data sent in the previous time slot.

[0110] The protocol data may be obtained, and according to the protocol data, an initial transmission window corresponding to the protocol data may be determined in a transmission cycle.

[0111] Optionally, the initial transmission window corresponding to the protocol data can be determined in the transmission cycle in the following manner: determine the transmission duration corresponding to the protocol data to be transmitted; determine whether the transmission duration is greater than a preset duration; if so, determine the initial transmission window corresponding to the protocol data in the transmission cycle based on the preset duration; if not, determine the initial transmission window corresponding to the protocol data in the transmission cycle based on the transmission duration.

[0112] For example, assuming that the preset duration is 6 time slots, if the transmission duration corresponding to the protocol data is 15 time slots, then according to the preset duration, the initial transmission window is determined to be 6 time slots; if the transmission duration corresponding to the protocol data is 4 time slots, then according to the transmission duration, the initial transmission window is determined to be 4 time slots.

[0113] S202: Determine whether there is business data to be transmitted in the initial transmission window.

[0114] The priority of business data is higher than that of protocol data.

[0115] The priorities may be pre-set, and the order of priorities is not limited here.

[0116] The service data may include BLE audio service data, WiFi service data, etc., which are not limited here.

[0117] Whether there is service data to be transmitted may be detected at intervals of a first duration within a duration corresponding to the initial transmission window.

[0118] S203: If yes, then update the initial transmission window to obtain at least one target transmission window according to the transmission period of the service data, and transmit the protocol data in the at least one target transmission window.

[0119] The transmission period can be used to indicate the period corresponding to the transmission of business data.

[0120] The target transmission window may be used to represent the transmission window after the initial transmission window is dynamically adjusted.

[0121] If there is business data to be transmitted in the initial transmission window, the transmission time period corresponding to the business data can be determined. According to the start time of the transmission time period, the initial transmission window is updated to obtain at least one target transmission window. According to the at least one target transmission window, the protocol data is transmitted.

[0122] Optionally, the initial transmission window can be updated according to the transmission period of the business data to obtain at least one target transmission window in the following manner: determine whether the starting time of the transmission period exists in the initial transmission window; if so, update the initial transmission window according to the starting time of the transmission period and the transmission period to obtain multiple target transmission windows; if not, determine the end time of the transmission period according to the starting time of the transmission period and the transmission period, update the end time to the starting time of the initial transmission window, and obtain a target transmission window.

[0123] Optionally, the data transmission method further includes transmitting business data, and the business data may be transmitted in the following manner: transmitting the business data in a transmission period of the business data.

[0124] S204: If not, transmit the protocol data in the initial transmission window.

[0125] If there is no service data to be transmitted in the initial transmission window, target protocol data to be transmitted may be determined according to the initial transmission window and the protocol data, and the target protocol data may be transmitted in the initial transmission window.

[0126] Optionally, the target protocol data to be transmitted may be determined according to the initial transmission window and the protocol data in the following manner: first data corresponding to the initial transmission window is determined in the protocol data, and the first data is determined as the target protocol data to be transmitted.

[0127] The data transmission method provided in this embodiment determines the initial transmission window corresponding to the protocol data in the transmission cycle, and the starting time of the initial transmission window coincides with the starting time of the transmission cycle, and determines whether there is business data to be transmitted in the initial transmission window, and the priority of the business data is higher than the priority of the protocol data. If so, the initial transmission window is updated according to the transmission period of the business data to obtain at least one target transmission window, and the protocol data is transmitted in at least one target transmission window. If not, the protocol data is transmitted in the initial transmission window. In this way, in a complex scenario where multiple services coexist, the priority of the protocol data in the Bluetooth service transmission is improved, and the initial transmission window is dynamically adjusted according to the business data, which ensures the timeliness and throughput of the protocol data transmission and improves the reliability of information transmission.

[0128] Next, combine Figure 5 , the process (S203) of updating the initial transmission window to obtain at least one target transmission window according to the transmission period of the business data is explained.

[0129] Figure 5 A flowchart of another data transmission method provided by an embodiment of the present application. Based on the above embodiment, see Figure 5 , the method comprising:

[0130] S501: Determine whether the start time of the transmission period exists in the initial transmission window.

[0131] If yes, execute S502;

[0132] If not, execute S504.

[0133] The starting time of the transmission period can be used to indicate the starting time corresponding to the transmission of service data.

[0134] The start time of the transmission period may be determined, and it may be determined whether the start time of the transmission period exists in the initial transmission window.

[0135] S502: Determine a period between a start time of an initial transmission window and a start time of a transmission period as a first target transmission window corresponding to the protocol data.

[0136] A period between a start time of the initial transmission window and a start time of the transmission period may be determined, and the period may be determined as a first target transmission window corresponding to the protocol data.

[0137] S503: Determine a second target transmission window corresponding to the protocol data according to the first target transmission window and the initial transmission window.

[0138] The multiple target transmission windows include a first target transmission window and a second target transmission window.

[0139] The time period corresponding to the first target transmission window may be subtracted from the time period corresponding to the initial transmission window to obtain a second time period. At the end of the transmission time period, the second target transmission window corresponding to the protocol data is determined according to the second time period.

[0140] S504: Update the start time of the initial transmission window according to the end time of the transmission period to obtain a target transmission window.

[0141] The end time of the transmission period can be determined according to the start time of the transmission period and the transmission period, and the start time of the initial transmission window can be updated according to the end time of the transmission period to obtain a target transmission window.

[0142] Next, combine Figure 6 , an example is given of a process of updating an initial transmission window to obtain at least one target transmission window according to a transmission period of business data.

[0143] Figure 6 A schematic diagram of another transmission cycle provided in an embodiment of the present application. Figure 6 , Figure 6 Three transmission cycles may be included.

[0144] Assuming that there is WiFi service data to be transmitted in the first transmission cycle, the start time corresponding to the WiFi service data is determined, and it is determined that the start time does not exist in the initial transmission window, and the start time of the initial transmission window is updated according to the end time of the transmission period to obtain the first target transmission window. The first target transmission window may include 2 transmission time slots and 2 reception time slots.

[0145] Assuming that there is BLE audio service data to be transmitted in the second transmission cycle, the start time corresponding to the BLE audio service data is determined, and it is determined that the start time exists in the initial transmission window, and the period between the start time of the initial transmission window and the start time of the transmission period is determined as the first target transmission window corresponding to the protocol data, and the second target transmission window corresponding to the protocol data is determined according to the first target transmission window and the initial transmission window, and the multiple target transmission windows include the first target transmission window and the second target transmission window. Among them, the second target transmission window can include 1 sending time slot and 1 receiving time slot.

[0146] The implementation content of each step in the embodiment of the present application can refer to the description of the corresponding steps or operations in the above method embodiment, and repeated content will not be repeated.

[0147] The data transmission method provided in this embodiment determines whether the starting time of the transmission period exists in the initial transmission window; if so, the period between the starting time of the initial transmission window and the starting time of the transmission period is determined as the first target transmission window corresponding to the protocol data; according to the first target transmission window and the initial transmission window, the second target transmission window corresponding to the protocol data is determined; wherein the multiple target transmission windows include the first target transmission window and the second target transmission window; if not, according to the starting time of the transmission period and the transmission period, the end time of the transmission period is determined, and the end time is updated to the starting time of the initial transmission window to obtain a target transmission window. In this way, in a complex scenario where multiple services coexist, the priority of protocol data in Bluetooth service transmission is improved, the initial transmission window is dynamically adjusted according to the service data, the timeliness and throughput of protocol data transmission are guaranteed, and the reliability of information transmission is improved.

[0148] In a possible implementation, the transmission cycle may include a target transmission window or an initial transmission window, and an idle transmission window. The data transmission method further includes dynamically transmitting the data to be transmitted within the idle transmission window of the transmission cycle, and the data to be transmitted may include service data or protocol data.

[0149] Next, combine Figure 7 , the process of dynamically transmitting the data to be transmitted within the idle transmission window of the transmission cycle is explained.

[0151] S701. Determine an idle transmission window of a transmission cycle according to a target transmission window or an initial transmission window.

[0152] The idle transmission window may be used to indicate a transmission window corresponding to a period other than an initial transmission window within a transmission cycle.

[0153] When there is business data to be transmitted in the initial transmission window, the idle transmission window of the transmission cycle can be determined according to the target transmission window; when there is no business data to be transmitted in the initial transmission window, the idle transmission window of the transmission cycle can be determined according to the initial transmission window.

[0159] The priority level corresponding to at least one piece of data to be transmitted may be determined, and the transmission order corresponding to at least one piece of data to be transmitted may be determined in descending order of priority level.

[0160] For example, the service data corresponding to the BLE audio service has a higher priority than the protocol data.

[0161] S704: Determine target data in at least one piece of data to be transmitted according to the transmission order.

[0162] The target data may be used to indicate data that is preferentially transmitted in an idle transmission window.

[0163] In the transmission order, the candidate data that is at the front of the order may be the target data.

[0164] S705: Determine whether the transmission duration corresponding to the target data is less than the idle transmission window.

[0165] If yes, execute S706;
