It should be understood that the embodiments described are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

In addition, the character "/" herein generally indicates that the former and latter associated objects are in an "or" relationship.
Referring to fig. 1, a schematic structural diagram of an electronic device provided in an embodiment of the present application is shown. The electronic device is a device for providing voice and/or data connectivity to a user, and the embodiment of the present application is not limited to the specific form thereof. For example, in addition to the mobile phone 100 shown in fig. 1, the mobile phone may be a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), or the like.
Fig. 2 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. As shown in fig. 2, the electronic device includes an application processor AP chip and a communication processor CP chip, where the AP chip and the CP chip are connected through PCIE communication. It can be understood that the AP chip is used for processing application data, the CP chip is used for processing communication service, and the AP chip and the CP chip perform information transmission through the PCIE.
Specifically, a WIFI MAC HW module is arranged on the CP chip, the WIFI MAC HW module is a hardware of a WIFI MAC protocol layer, and the CP chip can receive and transmit WIFI data with an external device (other devices) through the WIFI MAC HW module. Of course, the specific form and implementation manner of the WIFI MAC HW module are not limited in the embodiment of the present application, and the CP chip may also implement the operation through other module units of the protocol layer, for example, through a mode of protocol layer software.
In the system design of the electronic device, in order to save power, the PCIE module is usually controlled to enter the sleep state when there is no service. When the PCIE module is in the sleep state, if the WIFI MAC HW module competes for an air interface resource, the PCIE module is awakened at the same time (awakening the PCIE module needs a certain time, which may be understood as an action of awakening the PCIE module triggered) under the condition that packet sending is required, and a packet in the memory of the AP chip of the application processor is acquired through the PCIE module. However, the wake-up time of a PCIE module is long, for example, 80 μ s is required. Under the condition that the PCIE module is not yet woken up, the CP chip usually cannot fetch the packet in the memory of the AP chip, thereby causing an exception to packet transmission.
Based on this, the embodiment of the application provides an information transmission method. Referring to fig. 3, a schematic flow chart of an information transmission method is provided in the embodiment of the present application. The method is applicable to the electronic device shown in fig. 1 and 2, as shown in fig. 3, which mainly comprises the following steps.
Step S301: and if the communication service requirement exists, performing air interface competition.
In wireless communication, an air interface may be understood as a virtual logic interface, information transmission specifications, such as a use frequency, a bandwidth, an access timing, an encoding method, and the like of each channel, are defined on the air interface in a related communication standard, and an electronic device performs information transmission using the air interface.
To avoid collision, when there is a communication service requirement, the electronic device usually obtains the air interface occupation time through an air interface contention mechanism, so as to reduce the probability that multiple users send messages at the same time. For example, in the electronic device shown in fig. 2, the WIFI MAC HW module on the CP chip preempts air interface resources. Certainly, the embodiment of the present application does not limit the specific form and implementation manner of the WIFI MAC HW module, and the CP chip may also implement the operation through other module units of the protocol layer.
Step S302: and after the competition reaches the air interface, if a packet sending service requirement exists, triggering the awakening action of the communication bus module, and sending a supplementary message through the air interface.
The communication bus module related to the embodiment of the present application may include a PCIE module, a USB module, and/or a Secure Digital Input and Output (SDIO) module. Hereinafter, the technical solution of the present application is described by taking a PCIE module as an example, and it is to be understood that the invention should not be taken as a limitation to the protection scope of the present application.
The application scenario of the technical scheme provided in the embodiment of the present application is that after the PCIE module is dormant, that is, at this time, the PCIE module is in a dormant state.
In the conventional scheme, after a CP chip competes for an air interface, if there is a packet sending service requirement, a PCIE module is awakened, and a packet in a memory of an AP chip of an application processor is acquired through the PCIE module. However, since the wake-up process of the PCIE module is relatively slow, for example, after a Distributed Inter-frame Spacing (DIFS) competes for an air interface, a message in the memory of the AP chip cannot be fetched, which may cause data transmission abnormality.
Based on this, in the embodiment of the present application, the supplementary message is sent through the air interface while the wake-up action of the PCIE module is triggered. Specifically, the WIFI MAC HW module may first group a supplementary message, and send out the supplementary message through the air interface, thereby striving for time for subsequently obtaining a message in the memory of the AP chip, and avoiding data transmission abnormality to the greatest extent.
In order to ensure that the message in the memory of the AP chip can be obtained after the supplementary message is sent, the length of the supplementary message should be matched with the wake-up duration of the PCIE module. For example, the wake-up duration of the PCIE module is 80 μ s, and accordingly, the sending time of the supplemental packet should be equal to or greater than 80 μ s, so that after the supplemental packet is sent, the service packet in the memory of the application processor chip may be obtained through the communication bus module.
Step S303: and acquiring the service message in the memory of the AP chip through the communication bus module.
It can be understood that according to the preset length of the supplemental message, when the supplemental message is sent, the PCIE module is already awake, and at this time, the data in the memory of the application processor chip may be acquired through the communication bus module, so as to perform normal information transmission. It can be understood that the data acquired in the memory of the AP chip is a service packet corresponding to the communication service requirement.
Specifically, when the CP chip receives and transmits data through the WIFI MAC HW module, the service packet obtained from the memory of the AP chip is a WIFI data packet.
By adopting the technical scheme provided by the embodiment of the application, the supplementary message is inserted in the awakening process of the communication bus module, so that time is strived for the subsequent communication bus module to obtain the message of the AP chip, message sending abnormity is avoided, and the air interface resource which is obtained through competition is effectively utilized.

As shown in fig. 4, the apparatus includes a contention over air module 401, a wakeup module 402, and a messaging module 403.
