The present application claims priority to Chinese Patent Application No. 201610700176.7, filed on Aug. 22, 2016, entitled "Wake-up Method, Receiving Device, and Transmitting Device", the entire contents of which are incorporated by reference. In this application.

Technical field

The present application relates to the field of wireless local area networks, and more particularly, to a wake-up method, a receiving end device, and a transmitting end device.

Background technique

With the development of mobile communication technologies, mobile applications are increasingly diversified and device functions are continuously enriched. Reducing the energy consumption of equipment has become one of the important technical goals of wireless networks. Among them, node intelligent power saving is a main means to achieve low energy consumption. How to wake up a node after power-saving sleep, for example, how to wake up a node is a difficult problem to be solved when emergency service demand or real-time business demand arises. In the field of Wireless Local Area Networks (WLAN), the related solutions in the traditional 802.11 protocols (for example, 802.11b, 802.11a, 802.11g, 802.11n, 802.11ac, etc.) are mainly focused on optimizing the sleep policy of the device. .

In WLAN, a considerable part of the energy of the device is wasted on idle listening without receiving signals. Therefore, in addition to optimizing the dormancy strategy, reducing the energy consumption of the device in idle listening is another technical way to reduce energy consumption. A current solution is implemented using a Low Power Wake-Up Receiver (LP-WUR), which may be referred to simply as a Wake-Up Receiver (WUR). The core idea of the solution is the receiving device, such as station (STA), in addition to the traditional main radio, such as 802.11 main radio, Wireless Fidelity (Wi-Fi) main radio In addition to, add a WUR.

In this solution, the sending end device, such as an access point (AP), requests the sleeping STA to perform a specific behavior, which is generally completed in several steps. The AP sends a wake-up packet on the WUR channel. After receiving the wake-up packet, the STA sends a Power Save-Poll (PS-Poll) frame through the main radio to inform the AP that it has been woken up. The AP sends a specific frame through the main radio channel to indicate the behavior to be performed by the STA, for example, instructing the STA to report data to the AP. After receiving the specific frame, the STA reports the data through the main radio channel.

In this process, the sending end device wakes up the receiving end device and requires its execution behavior. The signaling frame has many interactions and the process is complicated. The receiving end device has a slow response speed to the command and is not conducive to the energy saving of the receiving end device.

detailed description

The technical solutions in the present application will be described below with reference to the accompanying drawings.

The wake-up method in the embodiment of the present application can be applied to a WLAN, and can also be applied to other various communication systems, for example, a Global System of Mobile Communication (GSM) system, Code Division Multiple Access (CDMA). System, Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS) system, Long Term Evolution (LTE) system, LTE frequency division duplex (Frequency Division) Duplex, FDD) System, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, and future communication systems .

Taking the WLAN as an example, the sending end device in the embodiment of the present application may be an AP, and the corresponding receiving end device is an STA; or the sending end device may be an STA, and the corresponding receiving end device is an AP, which is not limited in this application.

FIG. 1 is a schematic diagram of a typical application scenario of a WLAN. As shown in FIG. 1, the WLAN includes a source device (such as the AP shown in FIG. 1) and a sink device (such as the STA shown in FIG. 1). The AP is responsible for two-way communication with a plurality of STAs, for example, the AP shown in FIG. 1 transmits downlink data to STAs (for example, STA1 and STA2 in FIG. 1), or the AP receives uplink data from STAs (for example, STA3 in FIG. 1). . It should be understood that the number of APs and STAs shown in FIG. 1 is merely illustrative, and any number of APs and STAs may be included in the WLAN.

2 is a schematic diagram of interaction between a transmitting device and a receiving device in an existing low energy solution. The receiving device includes a main radio 2 and a WUR, and the transmitting device includes a main radio 1 . When the main radio 2 of the receiving device goes to sleep, the low power WUR wakes up and starts working. If the transmitting device needs to communicate with the receiving device, the transmitting device first sends a wake-up packet to the WUR of the receiving device through the WUR channel. After the WUR correctly receives the wake-up packet sent to itself, it wakes up the main radio 2 of the receiving device. The sender device communicates with the awake main radio 2 through the main radio 1 . After the main radio 2 communicates with the sender device, the WUR listens for a wake-up packet sent to itself to wake up the main radio 2 when the wake-up packet is received.

The above technology uses a low power WUR instead of the main radio 2 to listen to the channel when the receiving device is idle, which can effectively reduce the energy waste of the receiving device in the idle listening. In order to achieve low power consumption, WUR generally has low complexity in terms of circuit structure and frame (for example, wake-up packet) structure design. The power consumption of the WUR listening state is about 0.1 to 1% of the main radio 2, that is, less than 100 uW.

It should be understood that the main radio of a receiving device can only be woken up by the WUR corresponding to the receiving device. The main radio is usually also called the main transceiver module or the main radio module and the main radio. In the absence of special instructions in this document, the main radio and WUR refer to the main radio and WUR of the same receiving device. The sender device may or may not include the WUR. When the sender device does not include the WUR, the main radio device may also be considered as a conventional transceiver.

It should be understood that the purpose of waking up the main radio is to leave the main radio in an ON state. Therefore, the "wake up main radio" includes the following cases: the main radio is turned off (off), that is, the sleep state, "wake up the main radio" refers to the state in which the main radio is turned ON; the main radio is turned ON. The state, "wake up the main radio" refers to maintaining the state of the main radio.

With the increasing diversification of wireless devices, the Internet of Things (IoT) has become the trend of wireless networks in the future. Therefore, the functions of the device itself will play an important role in the IoT, and the appropriate behavior needs to be performed at the appropriate time. However, if the device is in a power saving state, and the network center control node (eg, the sender device) requires the device to perform the corresponding function or behavior. As shown in FIG. 3, the transmitting end device requires the sleeping receiving device to perform a specific behavior, which is generally completed in four steps. Figure 3 shows an example where the sending device is an AP and the receiving device is a STA. Step 1. The AP sends a wake-up packet on the WUR channel. Step 2: After receiving the wake-up packet, the STA sends a Power Save-Poll (PS-Poll) frame through the main radio to inform the AP that it has been woken up. Step 3: The AP sends a specific frame through the main radio channel to indicate that the STA wants The performed behavior, for example, instructs the STA to report data to the AP. Step 4: After receiving the specific frame, the STA reports the data through the main radio channel, and sends a data frame. In this process, the sending end device wakes up the receiving end device and requires its execution behavior. The signaling frame has many interactions and the process is complicated. The receiving end device has a slow response speed to the command and is not conducive to the energy saving of the receiving end device.

In order to solve the above problem, the embodiment of the present application provides a wake-up method. FIG. 4 shows a schematic flow chart of the wake-up method 100 of the embodiment of the present application. The method 100 includes:

S110. The sender device generates a wake-up packet, where the wake-up packet includes first information for indicating a behavior that the receiver device needs to perform.

S120. The sending end device sends the wake-up packet to the receiving end device. Correspondingly, the receiving device receives the wake-up packet sent by the sending device.

S130. The receiving end device performs the behavior according to the first information.

In the wake-up method provided by the embodiment of the present application, in the wake-up packet sent by the sending end device to the receiving end device, the first information indicating the behavior required to be performed by the receiving end device is added, so that the receiving end device can receive the wake-up packet after receiving the wake-up packet. Direct execution behavior can avoid excessive signaling interaction between the sending device and the receiving device during the wake-up process, which can streamline the process, improve the response speed of the receiving device, and reduce the power consumption of the receiving device.

From the perspective of the receiving device, the waking method includes: the receiving device receives the wake-up packet, where the wake-up packet includes first information for indicating a behavior that the receiving device needs to perform; and the receiving device according to the The first information performs the behavior. From the perspective of the source device, the wake-up method includes: the sender device generates a wake-up packet, where the wake-up packet includes first information for indicating a behavior that the receiver device needs to perform; and the sender device sends the wake-up package.

It should be understood that the behaviors mentioned in the embodiments of the present application include, but are not limited to, the behaviors involved in the application of the IoT field.

It should also be understood that the wake-up packet in the embodiment of the present application may also be referred to as a wake-up frame.

In general, an existing wake-up packet may carry the following information or carry some of the following information:

In order to be compatible with the 802.11 legacy mode, the WLAN pilot legacy 802.11 preamble may be carried before the wake-up pilot wake up preamble in the wake-up packet;

Wake up the pilot wake-up preamble, its functions may include wake-up packet detection, channel estimation, etc.

Receiving an address to distinguish the WUR of the awakened receiving device;

Information used to identify the sender, such as the sending address, etc.

Other information, such as some control information, management information, etc.;

Check information, such as Frame Check Sequence (FCS).

A specific frame structure of a wake-up packet can be as shown in FIG. 5. The wake-up packet includes a legacy pilot legacy 802.11 preamble of 802.11 and a payload of wake-up packet of the wake-up packet. The payload of wake-up packet includes a wake-up pilot wake-up preamble, a medium access control header (MAC header), a frame body part, and an FCS. The payload of wake-up packet can also be referred to as a data part.

In the embodiment of the present application, the first information indicating the behavior that the receiving end device needs to perform is carried in the wake up packet. Specifically, carrying the first information may be a field including a behavior indicating that the receiving device needs to perform in the wake up packet. The field indicating the behavior that the receiving device needs to perform may be in the existing wake up packet Add a new field in the new, or reuse other functional fields in the existing wake up packet.

A possible implementation manner is that the wake up packet includes a first field indicating a behavior that the receiving end device needs to perform, and the first field may be located in a payload of wake-up packet part, or in a wake-up packet. The data part part. Optionally, the first field may be located in the MAC header portion or in the frame body portion.

Another possible implementation manner is that the wake up packet includes a second field indicating whether the first information is included. When the second field indication includes the first information (for example, the second field is 1), further, the wake up packet further includes a first field indicating a behavior that the receiving end device needs to perform; when the second field When the indication does not include the first information (for example, the second field is 0), the first field is not included in the wake up packet.

Yet another possible implementation manner is that the wake up packet includes a third field indicating whether control information (or management information) is included. When the third field indication contains control information (or management information), for example, the third field is 1, further, the wake up packet includes a fourth field, which is used to indicate the control information (or management information) Different from other management information, such as control information that is different from the management working channel, is related to the behavior that the receiving device needs to perform. Further, the wake up packet includes a first field indicating a specific behavior.

Specifically, in an embodiment, the S120 sending end device sends the wake-up packet, where the sending end device may send the wake-up packet to the wake-up receiver WUR of the receiving end device. Correspondingly, the receiving end device may include a wake-up receiver WUR and a main transceiver main radio, and the receiving end device receives the wake-up packet, including: the receiving end device receives the wake-up packet through the WUR, and the wake-up packet is used by the receiving device Wake up the main radio.

In the embodiment of the present application, a control logic module can respond to and process the wake-up packet sent by the sender device. An example of the structure of the receiving end device may be as shown in FIG. 6. The receiving end device includes a main radio, a WUR, a logic control module, an execution module 1, and an execution module 2. The logic control module can perform the function of waking up the main radio on the one hand, and can perform specific actions on the other hand by executing the execution module 1 and/or the execution module 2. In particular, the main radio of embodiments of the present application can be used to communicate with other devices, typically having a receiving function and/or a transmitting function for receiving data and/or transmitting data. The main radio may include at least one of a receiver and a transmitter.

In an embodiment of the present application, the wake-up packet may further include second information for indicating whether to wake up the receiving function and/or the sending function of the main radio of the receiving device. The receiving device can perform operations on the main radio according to the second information, for example, waking up the necessary functions of the main radio according to the second information.

Specifically, the source device may include second information for indicating the awake mode in the wakeup packet. The awake mode refers to which function (receive function and/or send function) of the main radio is awake. The receiving function may correspond to a receiver; the transmitting function may correspond to a transmitter. That is, waking up the main radio may mean waking up at least one of the transmitters or receivers in the main radio. The awake mode may include at least one of the following modes: the transmitter and the receiver of the main radio do not need to wake up; wake up the transmitter of the main radio; wake up the receiver of the main radio; wake up the transmitter of the main radio And receiver. For example, 2bit can be used to indicate the wake-up mode, 00 means that the transmitter and receiver of the main radio do not need to wake up, 01 represents the transmitter that wakes up the main radio, 10 represents the receiver of the main radio, and 11 represents the wakeup main. The transmitter and receiver of the radio. The indication may be carried in a suitable field of the wake-up packet, which is not limited in this embodiment of the present application.

The embodiment of the present application can flexibly control whether the receiving function and/or the sending function of the main radio device wake up, according to the needs. To wake up the receiving function and/or the sending function, when the behavior indicated by the first information does not need to perform data transmission and reception, the receiving function and/or the transmitting function may not be woken up, thereby achieving better energy saving.

For example, for an embodiment in which the receiving device does not need to reply any information, nor is it ready to receive a downlink frame from the transmitting device, the transmitting device may include the second information 00 in the wake-up packet. For an embodiment in which the receiving device needs to send information, the transmitting device may include the second information 01 in the wake-up packet. When the transmitting device includes the second information 10 in the wake-up packet, the receiver of the receiving device wakes up and is ready to receive a downlink frame from the transmitting device. When the transmitting device includes the second information 11 in the wake-up packet, both the transmitter and the receiver of the receiving device wake up, and the receiving device can reply to the information and prepare to receive the downlink frame from the transmitting device.

In this embodiment, if the wake-up or sleep of the transmitter is considered to be determined by the receiving device, or implicitly determined according to whether the receiving device needs to transmit information, the transmitting device does not need to specify the state of the transmitter. At this time, the second information included in the wakeup packet of the source device indicates that only 1 bit can be needed. The 1 bit is used to indicate that the receiver does not need to wake up or to indicate that the receiver is awake.

It should be noted that the receiving end device wakes up the necessary modules according to the indication of the second information of the transmitting end device, and other modules can select the OFF (sleep) state to save energy. Of course, the receiving device can also determine whether other modules are awake or dormant according to their own needs, which is not limited in this embodiment of the present application.

In another embodiment of the present application, the wake-up packet itself may be used to wake up the main transceiver of the receiving device, without additional second information to indicate.

In a specific example, the main radio can be used to report data. The reported data here may be reported to the transmitting device. Execution module 1 and execution module 2 can be used to perform different types of actions, respectively. For example, execution module 1 is used to perform action 1, and execution module 2 is used to perform action 2. In the embodiment of the present application, the sending end device adds a first field corresponding to the first information in the Wake-up packet, and is used to indicate the behavior that the receiving end device needs to perform, and the first information carried by the receiving end device according to the first field. Perform the appropriate behavior.

It should be noted that the specific implementation of the receiving end device may be in multiple ways, and is not limited to the above structure. The receiving device may also implement the connection or control of different modules in other manners, which is not limited in this embodiment of the present application.

Optionally, as an embodiment, the behavior is that the first data is reported; and the S130 performs the behavior according to the first information, where the receiving device sends the report according to the first information. The first data. Specifically, the first information may be used to indicate that the behavior that the receiving end device needs to perform is to report the first data to the sending end device; S130, the receiving end device performs the performing according to the first information. The behavior may include: the receiving end device reporting the first data to the sending end device according to the first information. In contrast, the sending end device receives the reported first data.

Specifically, in an example, the first data is the data recorded by the receiving end device, that is, the behavior that the receiving end device needs to perform may be to instruct the receiving end device to report the recorded data to the sending end device. For example, the first data may be at least one of temperature information, humidity information, and brightness information collected by the receiving device. The specific steps of the wake-up method can be as shown in Figure 7:

Step 1: The sender device sends a wake-up packet on the WUR channel, where the wake-up packet includes first information for indicating a behavior that the receiving device needs to perform, and the first information passes the first field. carry. The behavior in Figure 7 is to report the recorded data to the transmitting device.

Step 2, the receiving device wakes up the main radio after receiving the wake-up packet including the first information (this It refers to the sending function of the main radio, and sends a Data frame on the main radio channel to report the first data recorded.

In the embodiment of the present application, after receiving the wake-up packet including the first information, the receiving device may select only the main radio device related to the reported data, and the necessary processing module is in a awake state, and the other is not related. The modules (such as Execution Module 1 and Execution Module 2) can remain dormant.

In another example, the first information is used to indicate data of a status of the receiving device. That is, the behavior indicating that the receiving end device needs to perform may be data indicating that the receiving end device reports the status of the receiving end device (eg, running state, working state, etc.) to the transmitting end device. For example, the data of the state of the receiving device may be data such as power information or operating temperature information.

Optionally, as shown in FIG. 8 , in the embodiment of the present application, before the receiving end device performs the behavior according to the first information, the method may further include: the receiving end device sends a wake-up confirmation. frame. Specifically, before the receiving end device performs the behavior according to the first information, the method may further include: the receiving end device sending a wake-up acknowledgement frame to the sending end device. Correspondingly, the sending end device receives the wake-up acknowledgement frame sent by the receiving end device. This solution is applicable to the situation where the receiving device cannot report data in time, for example, if data needs to be prepared before it can be reported. When the receiving device fails to report data in time, it first returns a wake-up confirmation frame indicating that it has awake to the transmitting device, and then reports the data to the transmitting device. Optionally, the wakeup acknowledgement frame may be a PS-Poll frame.

Optionally, as an embodiment, the behavior is: performing the first action; the S130, the receiving end device performing the behavior according to the first information, may include: the receiving end device according to the first information, Performing the first action. Specifically, the first information used to indicate that the receiving end device needs to perform the action may be: performing the first action; S130, the receiving end device performing the behavior according to the first information, may include: the receiving The end device performs the first action according to the first information.

Step 3: The receiving device sends the action feedback information on the main radio channel after the action is performed, or when the action is not completed, and the action feedback information is sent to the device. The result of this action execution, for example, the curtain has been closed or the curtain has failed to close. Specifically, when the action execution is successful, the action feedback information may be ACK of Action information; when the action is not completed beyond a predetermined threshold time, the action feedback information may be NACK of Action information.

In the embodiment of the present application, after receiving the wake-up packet including the first information, the receiving device may select only the main radio, the execution module 2 that performs the action, and the necessary processing module to be awake. Other unrelated modules (such as execution module 1) can remain dormant.

Specifically, the behavior indicating that the receiving end device needs to perform may be to instruct the receiving end device to perform a specified action (eg, the first action). For example, the action may be a specific action such as closing the curtain, turning on the power of the television, and turning on the power of the water heater. The steps of the specific wake-up method can be as shown in Figure 12:

Step 1: The sender device sends a wake-up packet on the WUR channel, where the wake-up packet includes first information for indicating a behavior that the receiving device needs to perform, and the first information passes the first field. carry. The behavior in Figure 12 is to perform a first action, for example, to close the curtain.

Step 2: After receiving the wake-up packet including the first information, the receiving device wakes up the main radio (at least wakes up its sending function), and performs an action of closing the curtain (performing the first action); then the receiving device is at the main radio.

Optionally, as an embodiment, the first information is a first behavior identifier that is N bits in length. Thus, instead of directly transmitting the content of the behavior that the receiving end device needs to perform, the N-bit identification indication can simplify the wake-up packet. The requesting, the sending end device and the receiving end device store third information for indicating a one-to-one correspondence between a plurality of behavior identifiers having a length of M bits and content of multiple behaviors, the multiple behaviors The first set formed is a complete set of behaviors that the receiving end device served by the transmitting device can perform. Optionally, N=M, where the multiple behavior identifiers with a length of M bits include the first behavior identifier.

It should be understood that the third information may be specified in the protocol, or may be determined by the sending end device and the receiving end device, which is not limited by the embodiment of the present application.

Specifically, the sender device and the receiver device may predefine a mapping table, which is used to indicate a one-to-one correspondence between the M bit behavior identifier and the content of multiple behaviors. The complete set of actions that the receiving device served by the sender device can perform constitutes a set of behaviors. The M bit behavior indicator can define up to 2 ^N different behaviors. For example, in Table 1, 8 bits can be used to define 256 behaviors.

Table 1 mapping table

M bit behavior identifier	Behavioral content
00000000	Wake up the main radio
00000001	Report temperature information
......	......
11111101	Turn on the water heater
11111110	Close the curtain
11111111	Reserved field

The length of the first information carried in the wake-up packet sent by the sending device to the receiving device is N bit. When the sender device wants the receiving device to perform some behavior, the first information is set to a corresponding value (for example, set to 00000001). After receiving the wake-up packet, the receiving device can learn the required behavior and perform corresponding operations according to the corresponding relationship in the mapping table (the corresponding temperature information is reported by 00000001). In the embodiment of the present application, the sending end device indicates the specific behavior content by sending the behavior identifier, and the amount of information is small, which conforms to the simple design principle of the WUP, and can also improve the efficiency of signaling transmission.

Optionally, as another embodiment, the first information is a first behavior identifier that is N bits in length. And storing, by the sending end device and the receiving end device, third information for indicating a one-to-one correspondence between a plurality of behavior identifiers having a length of M bits and content of the plurality of behaviors, where the plurality of behaviors are formed A set is a complete set of behaviors that the receiving end device served by the transmitting end device can perform. Before the receiving end device receives the wake-up packet sent by the sending end device, the method may further include: the receiving end device sending, to the sending end device, a behavior identifier indicating at least one length of N bits and at least one Fourth letter of one-to-one correspondence of behavior identifiers of length M bits And wherein N<M, the second set formed by the at least one behavior identifier corresponding to the N-bit length is a complete set of behaviors that the receiving end device can perform, and the at least one length is N bits. The first behavior identifier is included in the behavior identifier. Correspondingly, before the sending end device generates the wake-up packet, the sending end device may further receive, by the receiving end device, a behavior identifier that indicates at least one length of N bits and at least one behavior identifier that is M bits in length. The fourth information of the correspondence. The sending end device generates the wake-up packet, and the method includes: the sending end device generates the wake-up packet according to the third information and the fourth information.

Specifically, the mapping table shown in Table 1 is stored in the source device and the sink device. The mapping table includes a complete set of different behaviors that all receiving devices in the network may support. In fact, for a receiving device, its specific behavior may be a subset of the corpus. For example, the function of one sensor in the kitchen may be to report temperature information and humidity information, and does not require or support the action of closing the curtain.

The process of configuring and negotiating the behavior mapping of the sender device and the receiver device is given below. Both the sender device and the sink device store the mapping table shown in Table 1. The length of the first information carried in the wake-up packet sent by the sending device to the receiving device is N bit, where N is less than M. Thereby, the number of bits occupied by the first information can be further reduced. The negotiation process between the sender device and the receiver device is as follows.

Step 1: The receiving end device generates an N-M mapping table according to its own executable behavior and the content of Table 1, that is, indicating at least one behavior identifier of length N bits and at least one behavior identifier of length M bits. The fourth information of the correspondence. Among them, the behavior identifier of each N bit represents an action that can be performed by itself. At the same time, the logic control module of its own configuration saves the N-M mapping table in order to perform the execution behavior when receiving an instruction from the transmitting device. For example, when N is 2, the receiving device can configure the 2-bit behavior identifier to: 00 for the behavior to wake up the main radio, 01 for turning on the water heater, 10 for closing the curtain, and 11 for the reserved field. The N-M mapping table generated by the receiving device is: 00 corresponds to 00000000, 01 corresponds to 11111101, 10 corresponds to 11111110, and 11 corresponds to 11111111.

Step 2: At a certain stage after the receiving end device enters the network association phase or the receiving end device enters the network, the receiving end device sends the N-M mapping table (ie, 00 corresponding to 00000000, 01 corresponding to 11111101, 10 corresponding to 11111110, 11 corresponding to 11111111) to The sender device notifies the sender device of the behavior that the receiver device can perform.

Step 3: After receiving the N-M mapping table sent by the receiving device, the sending device queries the M bit behavior identifier in Table 1 to learn the behavior represented by the N bit behavior identifier (00 represents the behavior to wake up the main radio module. , 01 means to open the water heater module, 10 means to close the curtain, 11 is a reserved field), then store the N-M mapping table and configure its own logic control module, so as to send an instruction to the receiving end device to indicate that it performs the corresponding behavior. It should be understood that each receiving device corresponds to its own N-M mapping table. When the transmitting device can communicate with multiple receiving devices, the transmitting device needs to store an N-M mapping table corresponding to each receiving device.

Step 4: After receiving the N-M mapping table, the sending end device may send a mapping confirmation frame to the sending end device to notify the sending end device that the N-M mapping table has been successfully received. It should be understood that step 4 is an optional step.
