The actual scrambling method is an XOR operation of the WUR scrambling sequence and the bit sequence to be scrambled; or other logical operations such as the same OR, AND, or the like. The scrambling of the information bits in the wake-up radio frame is not to satisfy the requirements of the traditional communication system for Peak to Average Power Ratio (PAPR), but to encrypt or partially encrypt the information bits in the radio frame. Prevent WUR-STA from being awake maliciously. Among them, the basic principle of preventing malicious wake-up is that WUR-STA may not correctly acquire wake-up information or instructions in a wake-up radio frame scrambled using other scrambling sequences (ie, non-WUR scrambling sequences). To avoid triggering the operation of waking up the main module in the WUR-STA.

After ending the operation of scrambling the wake-up radio frame, the AP sends the target WUR-STA (or is directed to the target WUR-STA, that is, it needs to perform a Beam-forming (BF) operation before the transmission to improve the reception. At the same time of gain, some important information is also prevented from being eavesdropped; wherein the information required to implement the BF operation can be obtained from the stored channel information or obtained by the sounding channel to wake up the wireless frame.

After receiving the wake-up radio frame, the WUR-STA performs a second scrambling operation (ie, descrambling code) on the wake-up radio frame using the AP distribution or the pre-agreed WUR scrambling code sequence. After the real wake-up information is obtained, the corresponding operation is performed according to the instruction of the transmitted information.

In this embodiment, considering the simplicity of the description, only the WUR scrambling code sequence and the scrambling operation are taken as an example to illustrate how to prevent malicious wake-up from a third party, other sequences satisfying the physical layer encryption requirements and encryption or equivalently regarded as encryption. The operation is also within the scope of the embodiment.

Application example 2

When the STA closes the main module, the WUR module is turned on, and the sleep state is entered, the authorized AP (hereinafter referred to as AP) sends the updated WUR scrambling code sequence to the WUR-STA using the wake-up radio frame. After receiving the WUR scrambling sequence, the WUR-STA starts the main module to send an acknowledgement frame to the AP, and after ending the sending of the acknowledgement frame, closes the main module while keeping the WUR module in the on state, and enters the sleep state again. Alternatively, in the case where the WUR-STA has a transmission capability (ie, the main module is not used to transmit an acknowledgment frame), the WUR-STA transmits an acknowledgment frame to the AP in a signal form different from the WLAN radio frame (eg, in the form of a wake-up radio frame).

The modulation mode in which the AP sends the wake-up radio frame may be different from the modulation mode of the acknowledgement frame replied by the WUR-STA. For example, the AP uses a multi-carrier (MC) modulation + simple digital modulation (eg, OFDM + OOK) modulation to wake up the radio frame, and the WUR-STA uses single carrier modulation or single carrier modulation + simple digital modulation (eg, , FM+OOK) Modulation confirmation frame. Among them, multi-carrier modulation includes OFDM, etc.; single-carrier modulation includes amplitude modulation (AM), frequency modulation (FM), and equalization; simple digital modulation includes On-off Keying (OOK) and amplitude keying (Amplitude Shift Keying, ASK), Frequency Shift Keying (FSK), Phase Shift Keying (PSK), etc.

Application example 3

Before the main module enters the sleep state period, the station STA uses the main module to send a WLAN radio frame carrying the WUR scrambling code sequence (for scrambling the wake-up radio frame) to the authorized AP (hereinafter referred to as AP). After receiving the WLAN radio frame, the AP sends an acknowledgement frame to the station STA. Or, after the STA STA turns off the main module and turns on the WUR module to enter the sleep state period (that is, becomes WUR-STA), when the WUR-STA has the transmission capability (that is, the main module is not used to send the confirmation frame), WUR- The STA sends a wake-up radio frame carrying the WUR scrambling sequence to the AP. After receiving the above-mentioned wake-up radio frame, the AP sends an acknowledgement frame to the WUR-STA to complete the update or initial distribution of the WUR scrambling sequence.

Application example 4

The authorized AP (hereinafter referred to as the AP) sends a wake-up radio frame to the WUR-STA to wake up multiple target WUR-STA sites in which the main module is in the closed state. The method that may be used includes: wake-up identification information carrying multiple different WUR-STAs in the wake-up radio frame; or a wake-up identification information for simultaneously waking up multiple WUR-STAs (for example, a broadcast identifier, ie, at Some or all of the WUR-STA sites in the sleep state perform the wake-up master module operation after receiving the identity. The wakeup identification information includes at least one of the following: a MAC address, an association ID, a partial association ID, or other similar information used to identify the site.

The AP may use one or more of the following frame formats to implement the sending of the multi-STA site wake-up radio frame, and the wake-up radio frame sent to the multi-STA station carries the wake-up identification information of multiple different WUR-STAs.

The first type of wake-up radio frame format: traditional preamble + WUR preamble + first load + WUR preamble + second load + ... + WUR preamble + Nth load, as shown in Figure 9a.

The second wake-up radio frame format: traditional preamble + WUR preamble + first load + second load + ... + Nth load, as shown in Figure 9b.

The third type of wake-up radio frame format: traditional preamble + WUR preamble + K ₁ load + WUR preamble + K ₂ loads +... + WUR preamble + K _n loads, K ₁ + K ₂ +... + K _n = N, as shown in Figure 9c.

The fourth wake-up radio frame format: WUR preamble + first load, WUR preamble + second load, ..., WUR preamble + Nth load respectively occupy different sub-frequency resources in the traditional preamble frequency resource, as shown in Figure 9d Show.

The fifth wake-up radio frame format: the traditional preamble and the WUR preamble occupy the same frequency resource, and the first load, the second load, ..., the Nth load respectively occupy different frequency resources occupied by the traditional preamble and the WUR preamble Sub-frequency resources, as shown in Figure 9e.

Wherein, '+' indicates a combination in time; variables K ₁ to K _n , N are positive integers, and N represents the number of STA stations carried by the wake-up radio frame, and the i-th load includes the second i-th load for waking up Wakeup information of the wireless device, i=1~N.

The role of the traditional preamble is compatible with WLAN devices, that is, to protect the wake-up radio frames from interference by traditional WLAN devices.

If the above frame format is applied, the WUR-STA first needs to detect or match a specific synchronization sequence in the WUR preamble (for a WUR device that does not have the transmission capability, it is not necessary to detect whether the legacy preamble exists), if the synchronization sequence is detected , indicating that the currently received radio frame is a wake-up radio frame; otherwise, the detecting operation is continued. After detecting the wake-up radio frame, the WUR-STA needs to continue to detect whether the current wake-up radio frame contains the identification information of the site, for example, a MAC address. If the identification information is detected, then the site is the target site and needs to perform corresponding operations, such as waking up the main module of the site. If the identification information of the site is not detected in the current wake-up radio frame, then the site is not the target site. In this case, the WUR-STA needs to return to the beginning of the detection process after the end of the identification information retrieval process, that is, re-enter the process of detecting the synchronization sequence in the WUR preamble.

A single STA station transmission is a special case of this embodiment, and will not be further elaborated here. Awakening some or all of the WUR-STAs using broadcast means that all target WUR-STAs are aware of the scrambling code sequence used by the AP to transmit the broadcast wake-up radio frame (if the scrambled mode is used to encrypt the transmitted information). The learned manner includes: pre-defining the scrambling code sequence of the broadcast mode (this method may require the WUR-STA to first obtain a real wake-up message using a predefined scrambling code sequence, and determine whether the current wake-up radio frame is a broadcast wake-up radio frame); or Before sending a broadcast wake-up radio frame, when there are different target stations using different scrambling code sequences, the AP needs to make the target station use the same scrambling code sequence through the update operation. Other encryption methods and so on, no longer give detailed examples.

Application example 5

The WUR-STA performs BF operation on the receiving side to receive the wake-up radio frame, and the wake-up radio frame from the unlicensed AP direction is automatically filtered, which suppresses the possibility that the unauthorized device malicious wake-up operation succeeds to some extent. After the filtering operation is completed, the WUR-STA starts the detection process of waking up the radio frame and carrying the STA site identification information. For detailed detection steps, refer to the related content in the application example 4.

Sex. Therefore, it is an effective solution to meet the requirements of power saving, energy and information security.
