Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and more specifically, to a wireless communication method, apparatus, electronic device, and storage medium. Background Technology

[0002] In wireless communication scenarios requiring the coexistence of multiple protocols, problems such as long communication latency and low channel utilization exist. Due to these problems, existing technologies offer the following solutions to address scenarios with multiple protocols coexisting:

[0003] (1) Setting up multiple chips for multiple protocols, but this approach undoubtedly greatly increases the manufacturing cost of the product;

[0004] (2) For a single chip, overclocking is used to make multi-protocol coexistence possible in multi-protocol coexistence scenarios. However, overclocking will shorten the chip life and increase the chip usage cost.

[0005] (3) For a single chip, a dynamic bandwidth allocation algorithm is set up in the scenario of multiple protocols coexisting to achieve the coexistence of multiple protocols. Although the dynamic bandwidth allocation algorithm can reduce communication latency to a certain extent, the requirements of the algorithm on chip performance and the introduction of the algorithm itself will increase the manufacturing cost of the product.

[0006] In summary, existing solutions for wireless communication scenarios with multiple protocols coexisting significantly increase product costs. Therefore, there is an urgent need for a low-cost wireless communication method for such scenarios. Summary of the Invention

[0007] The purpose of this application is to provide a wireless communication method, apparatus, electronic device, and storage medium to solve the problem of high product cost in wireless communication scenarios where multiple protocols coexist.

[0008] In a first aspect, embodiments of this application provide a wireless communication method, comprising: after detecting the arrival of a communication task, acquiring the communication task and its task information; acquiring a bandwidth allocation scheme for the communication task according to a preset bandwidth allocation strategy with communication time slots as the minimum bandwidth allocation granularity; executing the communication task by invoking a physical channel, and then monitoring whether the next communication task has arrived. In the implementation of the above scheme, by setting the bandwidth allocation strategy to allocate bandwidth to the communication task with communication time slots as the minimum bandwidth allocation granularity, the cost of wireless communication in multi-protocol coexistence scenarios is effectively reduced.

[0009] Optionally, in this embodiment, the communication task is: a wireless communication task based on a standard protocol and / or a wireless communication task based on a proprietary protocol; the step of calling the physical channel to execute the communication task specifically means: calling the physical channel to execute a wireless communication task based on a standard protocol and / or a wireless communication task based on a proprietary protocol. In the implementation of the above scheme, the communication task can be a wireless communication task based on a standard communication protocol, a wireless communication task based on a proprietary communication protocol, or a wireless communication task composed of a combination of both, enabling the wireless communication method to adapt to more user scenarios and effectively improving its adaptability.

[0010] Optionally, in this embodiment, the bandwidth allocation strategy includes: a fixed allocation strategy, which allocates fixed bandwidth to communication tasks with communication time slots as the smallest bandwidth allocation granularity; and a non-fixed allocation strategy, which sets primary and secondary tasks, allocating all bandwidth to the primary task with communication time slots as the smallest bandwidth allocation granularity, while the secondary task only occupies bandwidth when transmitting data.

In the implementation of the above scheme, the task information only needs to obtain the communication task timestamp and the physical channel required for the communication task, effectively reducing the cost of wireless communication in scenarios with multiple protocols coexisting.

[0013] Optionally, in this embodiment, the wireless communication method further includes: allocating bandwidth for all communication tasks under the same timestamp. By synchronously allocating bandwidth for all communication tasks under the same timestamp, multi-protocol coexistence becomes possible, effectively reducing the cost of wireless communication in multi-protocol coexistence scenarios.

[0015] Optionally, in this embodiment of the application, the wireless communication device further includes: a timestamp generation module, which is connected to the task scheduling module and the physical channel respectively, and is used to provide the same timestamp reference for the task scheduling module and the physical channel.

[0018] Optionally, in this embodiment of the application, the bandwidth allocation strategy in the task scheduling module allocates bandwidth to wireless communication tasks based on standard protocols or wireless communication tasks based on proprietary protocols with the communication time slot as the minimum bandwidth allocation granularity.

[0038] Figure 1 A flowchart illustrating the wireless communication method performed by an electronic device (e.g., a device terminal) provided in the embodiments of this application:

[0039] This method can be applied to electronic devices (e.g., device terminals). The main idea is to allocate bandwidth for communication tasks using communication time slots as the smallest granularity. Implementation methods for the aforementioned wireless communication method may include:

[0040] S110: After detecting the arrival of a communication task, obtain the communication task and its task information;

[0041] S120: Obtain the bandwidth allocation scheme for the communication task according to a preset bandwidth allocation strategy with the communication time slot as the minimum bandwidth allocation granularity;

[0042] It should be noted that the bandwidth allocation in this embodiment does not only allocate bandwidth for the currently arriving communication task, but also for all communication tasks within the physical channel allocated to the current task. For example, in a scenario where Bluetooth audio and private audio coexist, if the private 2.4G communication task arrives first, then according to the preset bandwidth allocation strategy, all bandwidth is allocated to the 2.4G communication task. Subsequently, after the Bluetooth communication task arrives, bandwidth allocation needs to be performed for both the 2.4G communication task and the Bluetooth communication task.

[0043] S130: Call the physical channel to execute a communication task, and then monitor whether the next communication task has arrived.

[0044] In this embodiment, bandwidth allocation is performed on communication tasks with communication time slots as the smallest bandwidth allocation granularity, making it possible for multiple protocols to coexist on a single chip and reducing product manufacturing costs; it also effectively avoids communication conflict problems in multi-protocol coexistence scenarios and improves communication latency in multi-protocol coexistence scenarios; at the same time, it also greatly reduces the product's operating power consumption.

[0045] As an optional implementation of the above wireless communication method, the communication task can be a single communication task involving a single communication protocol or a combination of multiple communication tasks involving different protocols. These two implementations are described in detail below:

[0046] In the first implementation, the communication task is a single communication task involving a single communication protocol. For example, in a scenario where the standard Bluetooth protocol and the proprietary 2.4G protocol coexist, if the Bluetooth communication arrives before the proprietary 2.4G communication, a single communication task involving the standard Bluetooth protocol and a single communication task involving the proprietary 2.4G protocol are generated, and these two communication tasks arrive one after the other.

[0047] In the second implementation, the communication task involves multiple communication tasks with multiple communication protocols. For example, in a scenario where the standard Bluetooth protocol and the proprietary 2.4G protocol coexist, if Bluetooth communication and proprietary 2.4G communication arrive at the same time, a single communication task is generated. Under this communication task, two communication tasks are set up, one involving the standard Bluetooth protocol and the other involving the 2.4G protocol.

[0048] As an optional implementation of the above wireless communication method, the communication task can be a wireless communication task based on a standard protocol, a wireless communication task based on a proprietary protocol, or a wireless communication task composed of both standard protocol-based and proprietary protocol-based communication tasks. These three implementation methods are described in detail below:

[0049] In the first implementation, the communication task is a wireless communication task based on a standard protocol. For example, in a scenario where a user plays audio using a Bluetooth device, the communication task is simply a wireless communication task based on the standard Bluetooth protocol. In this first implementation, calling the physical channel to execute the communication task specifically means: calling the physical channel to execute a wireless communication task based on a standard protocol.

[0050] In the second implementation, the communication task is a wireless communication task based on a proprietary protocol. For example, in a scenario where a user plays audio using a 2.4G device, the communication task is simply a wireless communication task based on a proprietary 2.4G protocol. In this second implementation, calling the physical channel to execute the communication task specifically means calling the physical channel to execute a wireless communication task based on the proprietary protocol.

[0051] In the third implementation, the communication task is a wireless communication task composed of a standard protocol-based communication task and a proprietary protocol-based communication task. For example, in a scenario where the standard Bluetooth protocol and the proprietary 2.4G protocol coexist, if Bluetooth communication and proprietary 2.4G communication arrive simultaneously, then two communication tasks are set up, one involving the standard Bluetooth protocol and the other involving the 2.4G protocol. In this third implementation, calling the physical channel to execute the communication task specifically means: calling the physical channel to execute both the standard protocol-based wireless communication task and the proprietary protocol-based wireless communication task.

[0052] Optionally, the communication task in this application embodiment can be various standard communication protocols and / or proprietary communication protocols of different frequency bands such as BT, BLE, 2.4G, 5.8G, VHF or UHF.

[0053] As an optional implementation of the above wireless communication method, the bandwidth allocation strategy in step S120 can be a fixed allocation strategy or a non-fixed allocation strategy. These two implementations are described in detail below:

[0054] In the first implementation, the bandwidth allocation strategy is a fixed allocation strategy. This means that a fixed bandwidth is allocated to the communication task according to a certain bandwidth cycle, with the communication time slot as the smallest bandwidth allocation granularity. For example, in a scenario where Bluetooth audio and proprietary audio coexist, a fixed bandwidth is allocated to both the Bluetooth communication task and the proprietary 2.4G communication task according to a certain bandwidth cycle. Figure 2 Taking the scenario shown as an example, every 6 slots, 4 slots of bandwidth are allocated to the private 2.4G communication task, and 2 slots of bandwidth are allocated to the Bluetooth communication task.

[0055] In the scenario where Bluetooth audio and proprietary audio coexist in this embodiment, the preset bandwidth allocation strategy in this application embodiment allocates bandwidth to communication tasks with n*slot as the smallest granularity, where n = 1, 2, ...; slot is a Bluetooth communication time slot; that is, regardless of the length of the transmission packet, the transmission time is always an integer multiple of the slot; the time slot in this application embodiment is specifically as follows:

[0056] In the physical link of Bluetooth communication, a 625μs time slice can be considered as the time it takes for one Bluetooth device to send a packet to another device.

[0057] by Figure 2 Taking the allocation method shown as an example, n*slots are used as the smallest granularity:

[0058] The bandwidth can be allocated in 1*slot increments, with 4*1*slots of bandwidth allocated to the private 2.4G communication task and 2*1*slots of bandwidth allocated to the Bluetooth communication task every 6*1*slots.

[0059] Alternatively, with 2*slot as the smallest granularity, allocate 2*2*slot of bandwidth to the private 2.4G communication task and 1*2*slot of bandwidth to the Bluetooth communication task every 3*2*slot intervals.

[0060] The second implementation uses a non-fixed bandwidth allocation strategy, which involves setting primary and secondary tasks. The primary task is allocated all bandwidth, while the secondary task only uses bandwidth when transmitting data. For example, in a scenario where Bluetooth audio and private audio coexist, the Bluetooth communication task only uses bandwidth when transmitting data via Bluetooth, while the private 2.4G communication task uses all bandwidth at other times.

[0061] As an optional implementation of the above wireless communication method, the preset bandwidth allocation strategy can allocate bandwidth for wireless communication tasks based on standard protocols with the communication time slot as the minimum bandwidth allocation granularity, or it can allocate bandwidth for wireless communication tasks based on proprietary protocols. These two implementations are described in detail below:

[0062] The first implementation method is to use a preset bandwidth allocation strategy to allocate bandwidth to wireless communication tasks based on standard protocols with the communication time slot as the minimum bandwidth allocation granularity. For example, in the scenario where Bluetooth audio and proprietary audio coexist, bandwidth is allocated to standard Bluetooth communication tasks with n*slot as the minimum granularity, where n = 1, 2, ...; slot is the Bluetooth communication time slot.

[0063] The second implementation method is to use a preset bandwidth allocation strategy to allocate bandwidth for wireless communication tasks based on private protocols with the communication time slot of the wireless communication task based on the standard protocol as the minimum bandwidth allocation granularity. For example, in the scenario where Bluetooth audio and private audio coexist, bandwidth is allocated for private 2.4G communication tasks with n*slot as the minimum granularity, where n = 1, 2, ...; slot is the Bluetooth communication time slot.

[0064] Of course, in the embodiments of this application, the preset bandwidth allocation strategy can not only use the communication time slot of the standard protocol as the smallest granularity to allocate the bandwidth of the communication task, but also use the communication time slot defined by the user as the smallest granularity to allocate the bandwidth of the communication task. The specific process will not be described in detail, as long as the bandwidth allocation of the communication task can be achieved.

[0065] Preferably, in this embodiment of the application, the task information includes: a communication task timestamp and the physical channel required for the communication task.

[0066] Preferably, in this embodiment of the application, the wireless communication method further includes:

[0067] The start and end times of the communication task are determined based on the communication task timestamp;

[0068] The corresponding physical channel is invoked according to the physical channel required by the communication task to execute the communication task within the start and end time of the communication task.

[0069] Preferably, in this embodiment of the application, the wireless communication method further includes:

[0070] All communication tasks are allocated bandwidth based on the same timestamp.

[0071] It should be noted that when the wireless communication method proposed in this application involves communication tasks with multiple different protocols, the process of establishing a link between the local device and other electronic devices needs to be considered.

[0072] As an optional implementation of the above wireless communication method, the method for establishing a link between the local device and other electronic devices can be either by reserving a fixed bandwidth for link establishment, or by increasing the transmission interval of existing communication tasks and increasing the transmission packet length of existing communication tasks. After the local device establishes a link with other electronic devices, bandwidth allocation is performed using the bandwidth allocation scheme obtained in step S120. These two implementation methods are described in detail below:

[0073] In the first implementation, the method for establishing a link between the local device and other electronic devices is to use reserved fixed bandwidth. Figure 4 Taking the scenario shown as an example, this implementation method is as follows: In a scenario where Bluetooth audio and proprietary audio coexist, if the 2.4G communication task arrives before the Bluetooth communication task, then according to the bandwidth allocation strategy described above, the 2.4G communication task is allocated all the bandwidth. When the local machine establishes a link with the Bluetooth device involved in the communication task, the 2.4G communication task increases the transmission interval and reserves a fixed bandwidth for Bluetooth connection scanning in the interval between the two transmissions. For example, 5ms of bandwidth can be reserved for Bluetooth device connection scanning.

[0074] In the second implementation, the method for establishing a link between the local device and other electronic devices is to increase the transmission interval of existing communication tasks and increase the transmission packet length. For example, in a scenario where Bluetooth audio and proprietary audio coexist, the Bluetooth device has a trigger switch, such as a button or various interface messages, to trigger the Bluetooth device to enter connection scanning mode so that other Bluetooth devices can connect. If the 2.4G communication task arrives before the Bluetooth communication task, according to the bandwidth allocation strategy described above, the 2.4G communication task is allocated all bandwidth. When the local device establishes a link with the Bluetooth device involved in the communication task, the trigger switch is activated, and the device enters Bluetooth connection scanning mode. The 2.4G communication task reduces its bandwidth usage, i.e., increases the transmission interval and the packet length of each transmission, thus increasing the transmission delay of the 2.4G communication task. After the link is established, the transmission interval of the 2.4G communication task is reduced, i.e., the bandwidth of the 2.4G communication task is increased. Subsequently, the bandwidth allocation scheme obtained in step S120 is used for bandwidth allocation.

[0075] It should be noted that increasing the transmission interval, i.e., increasing the idle time of existing communication, allows this idle time to be used for other communication. The factor by which the transmission interval increases is always greater than the factor by which the packet length increases. For example, if the transmission interval increases by 10 times, the packet length will double.
