technical field

The embodiments of the present application relate to the communication field, and in particular to a wireless communication method, device, electronic equipment, and readable storage medium.

Background technique

With the widespread popularization of smart electronic devices and wireless networks, smart electronic devices have higher and higher requirements for battery life, and also put forward higher requirements for power consumption and power saving of wireless network functions of smart electronic devices. To meet wireless performance requirements, power consumption must also be minimized, thereby saving more power consumption.

At present, a spatial multiplexing (Spatial Multiplexing, SM) power-saving function is proposed. The SM power-saving function allows a wireless workstation to have only one working receiving link for a long period of time. That is, in the case of meeting the performance requirements of the scene, the receiving link can be switched through negotiation with the peer end through the protocol. After the peer end responds, the wireless workstation that sent the request immediately switches to a receiving link to receive subsequent wireless frames, and the hardware is turned off. corresponding link, thus saving power consumption.

However, in the actual application process, some manufacturers have differences or defects in implementing this function, resulting in related compatibility issues. After the requester sends a request to enter a receiving link, the access point (Access Point, AP) responds normally with an acknowledgment (Acknowledge, ACK), and the requester enters a receiving link and closes the rest of the receiving links. Sometimes the AP may not recognize or understand the request, causing the requesting device to work on a receiving link, but the AP still sends data with two spatial streams, resulting in the requesting device being unable to decode and receive data from the two spatial streams normally. The sending end cannot send single spatial stream data to the peer end according to the protocol negotiation, which also causes itself to fail to receive the corresponding wireless response, so it will continuously reduce the physical layer rate according to the rate selection algorithm until it is reduced to one spatial stream to send. The peer is correctly identified. That is to say, due to the difference in the consistency of the power saving function implemented by the AP manufacturer, the data cannot be received normally after the receiving link is switched, which not only fails to save power consumption, but also leads to abnormal communication.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to 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 them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific sequence or sequence. It should be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application can be practiced in sequences other than those illustrated or described herein, and that references to "first," "second," etc. distinguish Objects are generally of one type, and the number of objects is not limited. For example, there may be one or more first objects. In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.

The wireless communication method provided by the embodiment of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

It should be noted that the applicable scenario of the embodiment of the present application is a wireless fidelity (Wireless Fidelity, WIFI) communication scenario. Personal computer (Ultra-Mobile Personal Computer, UMPC), netbook or personal digital assistant (Personal Digital Assistant, PDA), etc., the embodiment of the present application does not limit the specific type of electronic equipment.

The meaning of the noun space flow in the embodiment of the present application is: the radio can send multiple signals at the same time, and each signal is a space.

An embodiment of the present application provides a wireless communication method, the method includes the following steps:

(1) sending a first request to the AP;

In this embodiment of the present application, the first request is used to request an access point (Access Point, AP) to send a single spatial stream signal.

(2) In the case of receiving the ACK sent by the AP, maintaining the first working states of the plurality of first receiving links within a preset duration;

The above-mentioned multiple first receiving links are receiving links that have been opened before sending the first request, and the above-mentioned first working state is the working state of the multiple first receiving links before sending the first request;

It should be noted that the implementation of existing products is in accordance with the protocol. After receiving the wireless Ack confirmation, it will enter the real single input single output (Simple Input Simple Output, SISO) state; if it does not receive the Ack, it will not enter the SISO state. . The current implementation is based on the protocol. For example, the peer AP still uses Multiple-In Multiple-Out (MIMO) spatial streams to send data. Since the electronic device has closed other receiving links, it cannot receive the data sent by the AP. MIMO streams, therefore causing interruption of communication errors.

In the embodiment of this application, after the AP listens to the first request, it sends an ACK in response. After the electronic device receives the ACK from the AP, it keeps all the opened receiving links in the working state for a preset period of time. After receiving the ACK, it does not switch to the single receiving link immediately, but maintains the multi-receiving link for a period of time.

(3) When the preset condition is met, control the second receiving link to stop working.

The above preset condition is to receive a preset threshold of single spatial stream signals sent by the AP within the preset time period, or to receive all signals continuously sent by the AP within the preset time period as single spatial stream signals. The receiving chain includes receiving chains other than the receiving chain corresponding to the single spatial stream signal among the plurality of first receiving chains.

In the embodiment of the present application, if within the preset time period, the preset threshold single spatial stream signals received from the AP, or within the preset time period, all the signals continuously received from the AP are single spatial stream signals, then it is judged that this When the AP has normally switched to sending a single spatial stream signal, the electronic device only reserves the receiving link corresponding to the single spatial stream signal, and turns off the power supply of the hardware of the remaining receiving link (that is, the second receiving link) to ensure normal reception. data while saving power.

Referring to FIG. 1, an embodiment of the present application provides a wireless communication method, the method is executed by an electronic device, and the method includes:

Step 101: Send a first request to the AP;

In the embodiment of the present application, in order to save power consumption, the electronic device (also referred to as the requesting end) sends a first request to the AP to request the AP to send a single spatial stream signal;

In a possible implementation manner, sending the first request to the access point AP specifically includes:

(1) Determine the usage scenarios of electronic equipment;

In this embodiment of the present application, the usage scenario of the electronic device may specifically refer to a current wireless power consumption scenario of the electronic device, for example, the current usage scenario is a high power consumption scenario or the current usage scenario is a low power consumption scenario. Specifically, the current power consumption scenario of the electronic device may be judged according to a preset power consumption policy.

(2) When the usage scenario matches the preset power consumption scenario, send a first request to the AP;

In the embodiment of the present application, if the determined usage scenario matches the preset power consumption scenario, the electronic device decides to send the first request to the AP.

Specifically, the preset power consumption scenario is a low power consumption scenario. If the electronic device judges that the current usage scenario is a low power consumption scenario, that is, a scenario where the power saving function is applicable, the electronic device sends a first request to the AP, requesting the AP to send a single Spatial stream signals, which can avoid multiple receiving links working at the same time, resulting in unnecessary power consumption. It is understandable that if the electronic device judges that the current high power consumption scenario is not applicable, that is, the power saving function is not applicable, then the electronic device can execute the frame exchange in the normal communication process, that is, there is no need to request the AP to send a single spatial stream Signal.

In a possible implementation manner, when the electronic device and the AP are in the first connection mode, the first request is the first frame; when the electronic device and the AP are in the second connection mode, the first request is the first frame Two frames, wherein the first connection mode is different from the second connection mode, and the first frame is different from the second frame.

Specifically, the above-mentioned first connection mode may refer to the case where the connection between the electronic device and the AP is a high throughput (High Throughput, HT) connection, and correspondingly, the first request is a spatial multiplexing energy-saving action (Spatial Multiplexing Power Save Action, SMPS Action) frame, it should be noted that Action is a frame type of the wireless medium access layer;

The above-mentioned second connection mode may refer to that when the connection between the electronic device and the AP is a Very High Throughput (VHT) connection, the first request is an Operating Mode Notification Action (OMN) Action) frame.

Step 102: In the case of receiving the ACK sent by the AP, maintain the first working state of multiple first receiving links within the preset duration;

It should be noted that the existing products are all implemented in accordance with the protocol. After receiving the wireless Ack confirmation, they will enter the real SISO state; if they do not receive the Ack, they will not enter the SISO state. The current implementation is based on the protocol. For example, if the peer AP still uses the MIMO spatial stream to send data, the electronic device has closed other receiving links and cannot receive the MIMO stream sent by the AP, which will lead to communication interruption errors.

In the embodiment of this application, after the AP listens to the first request (such as SMPS Action frame or OMN Action frame), it sends an ACK in response, and after the electronic device receives the ACK from the AP, it keeps all opened receiving chains within a preset time period. working condition of the road. In the specific implementation process, the preset duration can be realized by setting the protection timer. After the corresponding electronic device receives the ACK from the AP, it starts the protection timer and keeps all the receiving links working within the duration of the protection timer. State, that is, when the electronic device receives the ACK sent by the AP, it does not immediately switch itself to the single receiving link, but maintains the multi-receiving link working state for a period of time.

In a possible implementation manner, setting the duration of the protection timer may be set to a specific preset duration, or may also be set to a preset number of short interframe space (Short interframe space, SIFS) time.

In the embodiment of the present application, the preset duration can be directly set to X milliseconds (ms), that is, the duration of the protection timer is set to millisecond level; or the duration of the protection timer can be set to a preset number of SIFS times, that is, The duration of the protection timer is set to microsecond level.

Step 103: When the preset condition is met, control the second receiving link to stop working;

In the embodiment of the present application, if the preset threshold single spatial stream signals are received from the AP within the preset duration, that is, the number of single spatial stream signals continuously received by the electronic device from the AP reaches the preset number before the protection timer expires , it is judged that the AP has normally switched to sending single spatial stream signals at this time; if all the signals continuously received from the AP are single spatial stream signals within the preset time period, that is, the electronic device will continue to send signals from the AP until the protection timer expires. If all received signals are single spatial stream signals, it is judged that the AP has normally switched to sending single spatial stream signals at this time.

After judging that the AP has normally switched to sending a single spatial stream signal, the electronic device only reserves the receiving link corresponding to the single spatial stream signal, and closes the other receiving links (that is, one or more second receiving links) hardware Power supply, save power consumption.

It should be noted that the correspondence between the receiving link and the spatial stream signal can be pre-stored in the electronic device, and one receiving link corresponds to one spatial stream signal, so that if the AP sends a single spatial stream signal, the electronic device can Correspondingly determine the receiving link that needs to be reserved.

In a possible implementation manner, in a case where the number of received single spatial stream signals sent by the AP is less than a preset threshold within a preset time period, the first working states of the multiple first receiving links are maintained.

In the embodiment of this application, if within the protection period, it is found that the AP cannot complete the transmission of the preset threshold single spatial stream signal, indicating that the AP failed to normally switch to the single spatial stream signal transmission, then maintain the original multi-receiving chain Road status continues to work.

In a possible implementation manner, in a case where multiple spatial stream signals are received in all signals continuously sent by the AP within a preset time period, the first working states of the multiple first receiving links are maintained.

In the embodiment of this application, if it is found that the AP still sends messages of multiple spatial streams within the protection period, it means that the AP failed to normally switch to sending single spatial stream signals, then keep the original multi-receiving link state and continue to work.

The scheme of the present application is described below in conjunction with specific embodiments, and the specific process is as follows:

1. Wireless electronic devices connect to WiFi;

2. According to the wireless scene used by the electronic device and the power saving strategy, judge whether it is a power saving scene; if yes, go to step 3; otherwise, go to step 9;

3. The current connection sends an SMPS Action frame for an HT connection, and the current connection sends an OMN Action frame for a VHT connection, requesting the AP to switch the receiving link to a single receiving link;

4. The electronic device monitors the SMPS/OMN Action frame Ack and receives the confirmation; if the confirmation is received, go to step 5, otherwise go to step 8;

5. Set the protection timer to X ms or N SIFS times, and all receiving links within the protection timer maintain the original working state;

6. Within the protection timer time, if the continuously received packets are all single-space streams, and the number reaches Y or the timer expires, go to step 7; otherwise, go to step 8;

7. Confirm that the peer AP sends a packet to switch the spatial flow successfully, indicating that the receiving link is switched successfully, turn off the hardware power supply of the redundant receiving link, and cancel the timer;

8. Switching the receiving link is unsuccessful, keep all the original receiving links to continue to work;

9. Follow the normal frame exchange settings.

The control module 203 is configured to control the second receiving link to stop working when the preset condition is met, wherein the second receiving link is the first receiving link divided by the single space Other receiving links other than the receiving link corresponding to the streaming signal;

In a possible implementation manner, the control module is also used to

In the preset time period, when the number of single spatial stream signals received from the AP is less than the preset threshold, maintain the first working state of the plurality of first receiving links.

In a possible implementation manner, the control module is also used to

Within the preset time period, in a case where a multi-spatial stream signal is received in all the signals continuously sent by the AP, the first working state of the plurality of first receiving links is maintained.
