It should be noted that in this application embodiment, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0029] To better understand the solutions of the embodiments of this application, the following will be introduced first:

[0030] WUR beacon

[0031] In the existing Wireless Fidelity (WiFi) scenario, a low-power wake-up receiver can be used, such as Figure 1b As shown in the figure, the low-power wake-up receiver includes two parts: a main receiver and a wake-up receiver. The main receiver is used for data transmission and reception, and the wake-up receiver is used to wake up the main receiver. Before being woken up, the main receiver is in a closed state and does not perform data transmission and reception. The wake-up receiver receives a wake-up signal sent by a sending end (for example, an AP), and the wake-up signal can be an On-Off Keying (OOK) modulated signal, so that the wake-up receiver can detect the wake-up signal in an envelope detection manner, and the power consumption can be reduced to the order of several hundred microwatts, greatly reducing the power consumption of the user.

[0032] In order to keep the low-power wake-up receiver and the AP synchronized, a WUR beacon signal is periodically sent to transmit time information, as shown in Figure 1c The type dependent control of the WUR beacon MAC frame carries [5:16] 12-bit information in the Timing Synchronization Function (TSF) clock (timer) of the AP, and after the user receives the 12-bit information, the user updates the local TSF timer according to the time update criterion, so as to achieve the purpose of synchronization with the AP. The sending period and the offset of the sending starting position of the WUR beacon are indicated by an operation element sent by the AP, the period is the minimum TSF time unit number between two beacon sending times, and the starting position is the TSF time unit number offset relative to TSF0. When CSMA deferrals occur, the WUR beacon will be delayed in the current period, but will still be sent at the position determined by the sending period and the sending starting position of the WUR beacon in the subsequent period.

[0033] The WUR beacon signal is also used as a link maintenance signal. When a station (STA) does not receive the WUR beacon signal for a period of time, the STA must perform WUR search or switch to the mode of waking up the main communication module. When the wake-up signal is configured with a DRX period, that is, the wake-up signal is woken up to listen to the wake-up signal according to the DRX period, the wake-up signal is also used as a link maintenance signal. In the DRX period in which the wake-up signal is not sent, the AP can send a WUR beacon to serve as a link maintenance signal. The time during which the link maintenance signal is not received is determined by the user.

[0034] 5G RLM measurement

[0035] 5G NR terminal needs to measure downlink quality on Radio Link Monitoring Reference Signal (RLM-RS) resources and compare the measurement results with two thresholds Q out and Q in . RLM-RS resources can be all Synchronization Signal Block (SSB), or all Channel-State Information reference Signal (CSI-RS), or a mixture of SSB and CSI-RS. Q out and Q in are threshold values based on assumed PDCCH transmission parameters according to given BLER, Qout is defined as a threshold for which downlink cannot be reliably received, corresponding to out-of-sync block error rate (BLERout), and Qin is defined as a threshold for which downlink can be reliably received, corresponding to in-sync block error rate (BLERin).

[0036] 5G NR terminal measures link quality on configured RLM-RS resources every indication period and compares with Q out and Q in , when the link quality measured on all configured RLM-RS resources is worse than Q out , it reports out-of-sync to high layer, when the link quality measured on at least RLM-RS resources is better than Q in , it reports in-sync to high layer. High layer starts T310 timer when it receives N310 consecutive out-of-sync indications, and stops T310 timer when it receives N311 consecutive in-sync indications and T310 timer is running. When T310 timer expires, it is considered that radio link failure occurs and needs to be reselected.

[0037] The prior art determines the link quality by whether a link maintenance signal such as a WUR beacon signal and a WUR wake-up signal is received within a period of time. Since the access is competed in a CSMA manner, the number of beacon signals and WUR signals sent within a period of time cannot be accurately determined even if a signal period is configured, that is, when the AP fails to compete for the sending resource and the link quality is poor, both can cause the maintenance signal to be unable to be received. Therefore, the time accumulation method can only determine the link quality to a certain extent. In 5G NR, the link quality is measured on RLM-RS resources and compared with thresholds Q out and Q in The method can more accurately determine the link quality. However, considering that the low-power wake-up receiver uses envelope detection to detect signals to reduce power consumption, the signal-to-noise ratio or signal-to-interference noise ratio cannot be directly measured in the manner of measuring the link quality on RLM-RS resources in NR. On the other hand, in order to reduce the power consumption of the low-power wake-up signal, the OOK modulation manner is generally used, and the PDCCH is not sent. Therefore, when the low-power wake-up signal is introduced into the mobile communication system, the link monitoring manner of RLM in 5G NR cannot be directly used.

[0038] The method and device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings and specific embodiments and application scenarios.

[0039] Referring to Figure 2a The embodiments of the present application provide a method for determining the wake-up link quality. The execution subject of the method can be a terminal, and the specific steps include

[0040] Step 201: The terminal acquires a wake-up link quality indicator.

[0041] Step 202: In a case where the relationship between the wake-up link quality indicator and a preset threshold meets a preset condition, the wake-up link quality is determined, and a state switching operation is performed.

[0042] The wake-up link quality indicator is used to determine the case where the terminal receives a wake-up signal from a sending terminal.

[0043] In the embodiments of the present application, the sending terminal can be a network device such as a base station, and the sending terminal can be another terminal. The specific type of the sending terminal is not limited in the embodiments of the present application.

[0044] Specifically, the terminal in the embodiments of the present application can be a mobile terminal applied to an NR system, and the specific structure can be as follows Figure 2bAs shown in the figure, the terminal comprises two modules, a first module is a main communication module for transmitting and receiving mobile communication data, and a second module is a low-power wake-up receiver module for receiving a wake-up signal. When the main communication module does not receive and transmit data for a period of time, it enters a closed or sleep state. When the second module detects a wake-up signal sent by the sending end and the wake-up signal contains information of the receiving end, the first module is triggered to wake up, and the first module enters a working state to receive and transmit data. When the first module is not woken up by the second module, it is in a closed or sleep state and does not receive and transmit data.

[0045] The relationship between the wake-up link quality index and the preset threshold satisfies a preset condition, which can be that the wake-up link quality index is greater than the preset threshold, or that the wake-up link quality index is less than the preset threshold, or that the wake-up link quality index is greater than or equal to the preset threshold, or that the wake-up link quality index is less than or equal to the preset threshold.

[0046] In the embodiments of the present application, the terminal takes the case of receiving a wake-up signal from the sending end as a wake-up link quality index, determines the wake-up link quality, and performs a state switching operation, which can more effectively identify the cases of good and poor link quality, and this method can be better applied to envelope detection of a low-power wake-up receiver.

[0047] In a possible implementation, the wake-up link quality index comprises one or more of the following:

[0048] (1) the number of times that the terminal continuously satisfies a first condition within a preset time period;

[0049] (2) the number of times that the terminal continuously satisfies a second condition within a preset time period;

[0050] (3) the proportion of times that the terminal satisfies the first condition within a preset time period;

[0051] (4) the proportion of times that the terminal satisfies the second condition within a preset time period;

[0052] The first condition is that the terminal successfully receives a preamble sequence from the sending end, the second condition is that the terminal fails to receive the preamble sequence from the sending end, the proportion of times that the terminal satisfies the first condition is the proportion of times that the terminal satisfies the first condition in the total number of times that the sending end sends a wake-up signal, and the proportion of times that the terminal satisfies the second condition is the proportion of times that the terminal satisfies the second condition in the total number of times that the sending end sends a wake-up signal.

[0053] In a possible implementation, the state switching operation comprises any one of the following:

[0054] (1) waking up a main receiver;

[0055] (2) closing a main receiver;

[0056] (3) Turn off the wake-up receiver.

[0057] In a possible implementation, the preset threshold is a threshold configured by a high layer signaling of the network side, or a threshold preconfigured by the network side.

[0058] In a possible implementation, the preamble sequence is a periodic sequence or a non-periodic sequence, i.e., the sending and receiving of the preamble sequence can be periodic or non-periodic.

[0059] In a possible implementation, the preamble sequence is a common preamble sequence for detection of multiple or multiple groups of terminals, i.e., the common preamble sequence is used for detection of all receiving terminals (the terminal as an execution subject in the embodiment of the application is the receiving terminal).

[0060] In the case where the preamble sequence is a periodic sequence, the period of the preamble sequence is the sending period of the common preamble sequence.

[0061] In a possible implementation, the preamble sequence is a dedicated preamble sequence for detection of one or one group of terminals, i.e., the dedicated preamble sequence is used for detection of a specified receiving terminal.

[0062] In the case where the preamble sequence is a periodic sequence, the period of the preamble sequence is the sending period of the wake-up signal corresponding to the one or one group of terminals.

[0063] The scheme of the application will be described in detail below in the case where the preamble sequence is a common preamble sequence and a dedicated preamble sequence:

[0064] In the case where the preamble sequence is a common preamble sequence, the method flow is as follows:

[0065] (1) The sending terminal periodically or non-periodically sends the preamble sequence, which is used for monitoring of the wake-up link quality by multiple or multiple groups of receiving terminals.

[0066] (2.1) The receiving terminal counts the number of continuously detected common preamble sequences in a period of time, which is marked as low-power wake-up signal link quality indicator one, and is compared with the first threshold. If the number is greater than the first threshold, it is determined that the quality meets the condition.

[0067] (2.2) The receiving terminal counts the number of detected common preamble sequences in a period of time, and divides the number by the total number L of common preamble sequences sent by the sending terminal in the period of time to obtain a proportion, which is marked as low-power wake-up signal link quality indicator two, and is compared with the second threshold. If the number is greater than the second threshold, it is determined that the quality meets the condition.

[0068] (2.3) The receiver counts the number of consecutive failed common preamble sequences within a certain period of time and marks them as the low-power wake-up signal link quality index three. It compares the index with the third threshold. If the index is less than the third threshold, it is judged that the quality meets the condition.

[0069] (2.4) The receiver counts the number of times the common preamble sequence fails to be detected within a certain period of time, divides it by the total number of times the transmitter sends the common preamble sequence L within that period of time to obtain a ratio, which is marked as the low-power wake-up signal link quality index four. It is compared with the fourth threshold. If it is less than the fourth threshold, it is judged that the quality meets the condition.

[0070] When periodically sending / receiving preamble sequences, the low-power wake-up signal link quality metrics may include one or more of the four metrics described in (2.1) to (2.4) above.

[0071] When transmitting / receiving preamble sequences aperiodically, the low-power wake-up signal link quality index can be index one or / and index three.

[0072] (3.1) When the low-power wake-up signal link quality index is compared with the threshold and it is determined that the link quality meets the reliability transmission, the state switches to turn off the main receiver or continues to remain in the state of turning off the main receiver.

[0073] (3.2) When the low-power wake-up signal link quality index is compared with the threshold and it is determined that the link quality does not meet the reliability transmission requirement, the state is switched to wake up the master receiver. The wake-up receiver can also be turned off at the same time.

[0074] When periodically sending / receiving a preamble sequence, a time window is used to represent a period of time, such as... Figure 3 As shown, a time window contains L preamble sequence periods, and the starting point of the time window used for statistics at time tn by the receiver is t. n-(L-1) The end point of the time window is t n The receiver at time t n+1 The starting point of the time window used for statistics is t. n-L The end point of the time window is t n+1 .

[0075] Multiple receivers or groups of receivers are configured to receive a common preamble sequence in both the time and frequency domains, wherein the time domain location includes one or more of the following configurations:

[0076] (1) Period: The period for receiving the common preamble sequence;

[0077] (2) Receive the starting position offset of the common preamble sequence.

[0078] The leader sequence is a dedicated leader sequence, and the method flow is as follows:

[0079] (1) The sending end periodically or non-periodically sends a preamble sequence for one or a group of receivers to monitor the wake-up link quality.

[0080] (2.1) The receiver counts the number of consecutively successfully detected common preamble sequences within a certain period of time and marks them as the low-power wake-up signal link quality index one. It is compared with the first threshold. If it is greater than the first threshold, it is judged that the quality meets the condition.

[0081] (2.2) The receiver counts the number of times the common preamble sequence is successfully detected within a certain period of time, divides it by the total number of times the common preamble sequence is sent by the transmitter within that period of time to obtain a ratio, which is marked as the low-power wake-up signal link quality index two. It is compared with the second threshold, and if it is greater than the second threshold, it is judged that the quality meets the condition.

[0082] (2.3) The receiver counts the number of consecutive failed detections of the common preamble sequence within a certain period of time and marks it as the low-power wake-up signal link quality index three. It compares it with the third threshold. If it is less than the third threshold, it is judged that the quality meets the condition.

[0083] (2.4) The receiver counts the number of times the common preamble sequence fails to be detected within a certain period of time, divides it by the total number of times the common preamble sequence sent by the transmitter within that period of time to obtain a ratio, which is marked as the low-power wake-up signal link quality index four. It is compared with the fourth threshold, and if it is less than the fourth threshold, it is judged that the quality meets the condition.

[0084] When periodically sending / receiving preamble sequences, the low-power wake-up signal link quality metrics may include one or more of the four metrics described in (2.1) to (2.4) above.

[0085] When transmitting / receiving preamble sequences aperiodically, the low-power wake-up signal link quality index can be index one or / and index three.

[0086] (3.1) When the low-power wake-up signal link quality index is compared with the threshold and it is determined that the link quality meets the reliability transmission, the state switches to turn off the main receiver or continues to remain in the state of turning off the main receiver.

[0087] (3.2) When the low-power wake-up signal link quality index is compared with the threshold and it is determined that the link quality does not meet the reliability transmission requirement, the state is switched to wake up the master receiver. The wake-up receiver can also be turned off at the same time.

[0088] During periodic transmission, the transmitter sends a wake-up signal or preamble sequence in each DRX cycle, which is used by one or a group of receivers to monitor the wake-up link quality, such as... Figure 3 As shown, a time window contains L' DRX cycles, and the receiver at time t n The starting point of the time window used for statistics is t.n-(L’-1) , the end of the time window is t n , the receiving end receives the wake-up signal at time t n+1 , the start of the time window for statistics is t n-L’ , the end of the time window is t n+1 The wake-up signal contains a preamble sequence and data. The preamble sequence can be used to distinguish different receiving ends or groups of receiving ends, and the data carries other information of the wake-up signal. The sending end only sends the preamble sequence in the DRX cycle without sending the wake-up signal, and can use a preamble sequence different from the wake-up signal to distinguish, such as using a common preamble sequence or other sequences.

[0089] A receiving end or a group of receiving ends is configured with the time and frequency domain positions of receiving the wake-up signal, wherein the time domain position includes one or more of the following configurations:

[0090] (1) DRX cycle: cycle of receiving the wake-up signal;

[0091] (2) starting position offset of receiving the wake-up signal;

[0092] (3) offset in the DRX cycle of receiving the wake-up signal

[0093] (4) size of the time window of receiving the wake-up signal;

[0094] The receiving end only wakes up to listen to the wake-up signal at each of the above configured time domain resource positions.

[0095] The scheme of the present application is described below in combination with specific embodiments:

[0096] In this embodiment, the sending end is a base station, and the receiving ends are users (i.e., terminals), which are respectively users 1-8. Users 1-4 form a user group, which is identified as user group 1, and users 5-8 form another user group, which is identified as user group 2. In actual applications, the sending end and the receiving end can also be users.

[0097] The base station configures the time and frequency domain positions of the wake-up signal for user group 1 through high layer signaling of the main communication module, such as RRC signaling, wherein the time domain position includes one or more of the following configurations:

[0098] (1) DRX cycle: cycle of receiving the wake-up signal;

[0099] (2) starting position offset of receiving the wake-up signal;

[0100] (3) offset in the DRX cycle of receiving the wake-up signal

[0101] (4) size of the time window of receiving the wake-up signal;

[0102] User group 2 is not configured with the related configuration of wake-up signal, so the users in user group 1 listen to the wake-up signal according to the DRX cycle, and the users in user group 2 continuously listen to the wake-up signal.

[0103] It is assumed that users 1 and 4 in user group 1 and users 5 and 6 in user group 2 have no data reception and transmission in the main communication module for a period of time, so the users close or sleep the main communication module, and listen to the wake-up signal through the low-power wake-up receiving module. Users 1 and 4 listen to the wake-up signal according to the DRX cycle, that is, wake up to listen to the dedicated preamble sequence and subsequent data in each DRX cycle, and the low-power wake-up receiving module is also in a sleep state at the rest of the time, thereby saving power. Users 5 and 6 continuously listen to the wake-up signal.

[0104] The base station configures the time and frequency domain positions of the received common preamble sequence for multiple receiving ends or multiple groups of receiving ends through the high-level signaling of the main communication module, such as RRC signaling, wherein the time domain position includes one or more of the following configurations:

[0105] (1) Period - the period of receiving the common preamble sequence,

[0106] (2) Starting position offset of receiving the common preamble sequence;

[0107] The base station periodically transmits the common preamble sequence, and users 5 and 6 detect the common preamble sequence at time t n The starting point of the time window for statistics is t n-(L-1) , and the ending point of the time window is t n .

[0108] Users 5 and 6 count the number of continuously detected successful common preamble sequences in a period of time, and mark it as low-power wake-up signal link quality indicator one, which is compared with the first threshold. If it is greater than the first threshold, it is judged that the quality meets the condition.

[0109] Users 5 and 6 count the number of detected successful common preamble sequences in a period of time, divide it by the total number L of common preamble sequences sent by the sending end in the period of time, and obtain a proportion, which is marked as low-power wake-up signal link quality indicator two, which is compared with the second threshold. If it is greater than the second threshold, it is judged that the quality meets the condition.

[0110] Users 5 and 6 count the number of continuously detected failed common preamble sequences in a period of time, and mark it as low-power wake-up signal link quality indicator three, which is compared with the third threshold. If it is less than the third threshold, it is judged that the quality meets the condition.

[0111] The user 5 and 6 count the number of common preamble sequences detected in a period of time, divide the number by the total number L of common preamble sequences sent by the sending end in the period of time to obtain a proportion, marked as the fourth low-power wake-up signal link quality indicator, and compare the fourth low-power wake-up signal link quality indicator with the fourth threshold, and if the fourth low-power wake-up signal link quality indicator is less than the fourth threshold, it is determined that the quality meets the condition.

[0112] When the preamble sequence is periodically sent / received, the low-power wake-up signal link quality indicator can include one or more of the above four indicators.

[0113] When the preamble sequence is non-periodically sent / received, the low-power wake-up signal link quality indicator can be the first indicator or / and the third indicator.

[0114] When the low-power wake-up signal link quality indicator is compared with the threshold, it is determined that the link quality meets the reliable transmission, and the state is switched to the closed main receiver or continues to stay in the closed main receiver.

[0115] When the low-power wake-up signal link quality indicator is compared with the threshold, it is determined that the link quality does not meet the reliable transmission, and the state is switched to the wake-up main receiver, and the wake-up receiver can also be closed at the same time.

[0116] It is assumed that the dedicated preamble sequences used by the user group 1 are sequences 1 and 2, wherein the sequence 1 is used to indicate that there is no data load after the sequence, and the low-power wake-up receiving module can directly enter the sleep state after receiving the sequence, and the sequence 1 can adopt the same sequence as the common preamble sequence. The sequence 2 is used to indicate that there is data load after the sequence, and after receiving the data and decoding to determine the wake-up user identifier, the low-power wake-up receiving module of the user whose identifier is contained in the data load triggers the main communication module to wake up and enter the working state, and the low-power wake-up receiving modules of other users enter the sleep state.

[0117] The base station sends the preamble sequence 1 or 2 in each DRX cycle of the user group 1, and when the sequence 2 is sent, the data load is also sent at the same time, the users 1 and 4 count the number of common preamble sequences detected in a period of time, divide the number by the total number L of common preamble sequences sent by the sending end in the period of time to obtain a proportion, mark the proportion as the first low-power wake-up signal link quality indicator, and compare the first low-power wake-up signal link quality indicator with the first threshold, and if the first low-power wake-up signal link quality indicator is greater than the first threshold, it is determined that the quality meets the condition.

[0118] The users 1 and 4 count the number of common preamble sequences detected in a period of time, divide the number by the total number L of common preamble sequences sent by the sending end in the period of time to obtain a proportion, mark the proportion as the second low-power wake-up signal link quality indicator, and compare the second low-power wake-up signal link quality indicator with the second threshold, and if the second low-power wake-up signal link quality indicator is greater than the second threshold, it is determined that the quality meets the condition.

[0119] The users 1 and 4 count the number of common preamble sequences detected in a period of time, divide the number by the total number L of common preamble sequences sent by the sending end in the period of time to obtain a proportion, mark the proportion as the second low-power wake-up signal link quality indicator, and compare the second low-power wake-up signal link quality indicator with the second threshold, and if the second low-power wake-up signal link quality indicator is greater than the second threshold, it is determined that the quality meets the condition.

[0120] User 1 and 4 in a period of time statistics detection failure of the common preamble sequence, divided by the total number of common preamble sequence L sent by the terminal in the end of the time to get a proportion, marked as low power wake-up signal link quality indicator four, with the fourth threshold to do comparison, less than the fourth threshold is judged as quality meet the conditions.

[0121] Periodic transmission / reception preamble sequence, low power wake-up signal link quality indicator can contain one or more of the above four.

[0122] Non-periodic transmission / reception preamble sequence, low power wake-up signal link quality indicator can be index one or / and index three.

[0123] When the low power wake-up signal link quality indicator is compared with the threshold, it is determined that the link quality meets the reliable transmission, and the state is switched to close the main receiver or continue to stay in the closed main receiver.

[0124] When the low power wake-up signal link quality indicator is compared with the threshold, it is determined that the link quality does not meet the reliable transmission, and the state is switched to wake up the main receiver, and the wake-up receiver can also be closed at the same time.
