The following describes in detail a wake-up signal detection method provided in the embodiments of this application by using some embodiments and application scenarios thereof with reference to the accompanying drawings.
As shown in
In some embodiments, that the receiving end (such as a terminal) determines the sampling rate includes: the receiving terminal determines the sampling rate from a sampling rate set; where the sampling rate set includes a plurality of sampling rates.
In this embodiment, the receiving end may select the sampling rate according to a reception requirement, such as a sensitivity requirement and a power consumption requirement. Certainly, the receiving end may, for example, determine the sampling rate in other ways, for example, determining the sampling rate according to an indication of the sending end (such as a network-side device). In this example, the sending end may directly indicate the sampling rate.
In some embodiments, that the receiving end determines the sampling rate from the sampling rate set includes that the receiving end determines the sampling rate from the sampling rate set based on at least one of the following:
In some embodiments, the sampling rate in the sampling rate set is a divisor (approximate divisor) or multiple (approximate multiple) of a sampling rate used for sending a wake-up signal by the sending end, so that the sampling rate determined by the receiving end from the sampling rate set may meet at least one of the following requirements: 1) advance agreement is not required between the receiving end and the sending end; 2) no notification from the sending end is required; and 3) the receiving end does not need to notify the sending end.
In some embodiments, feature sequences included in the plurality of feature sequence sets have different lengths, for example, the plurality of feature sequence sets are feature sequence set 1, feature sequence set 2 and feature sequence set 3. The feature sequence set 1 includes a plurality of feature sequences with a length of 16, the feature sequence set 2 includes a plurality of feature sequences with a length of 8, and the feature sequence set 3 includes a plurality of feature sequences with a length of 4.
In some embodiments, the plurality of feature sequence sets respectively correspond to different sampling rates. In this embodiment, for example, the sampling rate determined by the terminal may be positively correlated with the length of the feature sequence included in the feature sequence set. For example, when the sampling rate determined by the terminal is s1, the terminal determines the feature sequence set 1 in this step; when the sampling rate determined by the terminal is s2, the terminal determines the feature sequence set 2 in this step; and when the sampling rate determined by the terminal is s3, the terminal determines the feature sequence set 3 in this step; where s1>S2>S3.
In some embodiments, each feature sequence set in the plurality of feature sequence sets includes a plurality of feature sequences, where each feature sequence in the plurality of feature sequences meets a requirement of maximizing a peak-to-side lobe ratio or a requirement of minimizing a maximum sidelobe value. In this embodiment, each feature sequence meets the requirement of maximizing the peak-to-side lobe ratio or the requirement of minimizing the maximum sidelobe value, that is, for the receiving end, the wake-up signal may be correctly detected by using a specified feature sequence in any one of the plurality of feature sequence sets.
In this step, the receiving end may monitor the wake-up signal based on the first feature sequence and the sampling rate determined in S202.
In some embodiments, before S206, the method further includes: the receiving end determines the first feature sequence from the feature sequence set based on a feature value.
In some embodiments, the feature value is determined according to one of the following: 1) being determined by the receiving end based on identification information of the receiving end; and 2) being indicated by a sending end.
In the wake-up signal detection method provided in this embodiment of this application, the receiving end determines the sampling rate, determines the feature sequence set matching with the sampling rate from a plurality of feature sequence sets based on the sampling rate, and monitors the wake-up signal based on the first feature sequence in the feature sequence set. The receiving end can determine the feature sequence set matching with the sampling rate from the plurality of feature sequence sets, which helps the receiving end to detect the wake-up signal so as to be correctly woken up, thus improving the communication performance.
The following describes in detail the wake-up signal detection method provided in this embodiment of this application with reference to several specific embodiments.
An embodiment of this application provides a wake-up signal detection method, so that the receiving end may implement compatibility of multi-sampling rate and low power consumption, and this embodiment includes the following steps.
In some embodiments, the sampling rate used by the receiving end does not need to be agreed between the receiving end and the sending end in advance, or the sending end does not need to notify the receiving end in advance.
In some embodiments, the receiving end may determine, according to its own judgment, which sampling rate to be used, for example, determining the sampling rate based on one or more of the following conditions: receiving sensitivity; a strength of a received signal; and quality of a received beacon signal (beacon or Keep-alive).
The feature sequence set group includes a plurality of feature sequence sets corresponding to the plurality of feature sequence sets described in S204.
In this embodiment, for example, the receiving end determines the feature value based on its own terminal identification (User Equipment_Identity Document, UE_ID), where for the feature value, refer to serial numbers in the first column in Table 1 below.
In this embodiment, for nother example, the receiving end is a terminal, and the feature value is pre-assigned by the network-side device.
It can be understood that in this step, the receiving end may monitor the wake-up signal based on the feature sequence Mi,q and the sampling rate si determined in step 1.
This embodiment may be combined with Embodiment 1, and this instance is mainly a detailed description of some details in Embodiment 1.
In this embodiment, the network-side device may assign a feature value q to the receiving end, and the receiving end (terminal) may determine, according to the receiving requirement such as sensitivity and power consumption, whether to select the following M16,j, M8,j or M4,j to monitor the wake-up signal.
M16,j, M8,j or M4,j are predefined sequences, which are used for different sampling rates respectively.
The sending end (such as the network-side device) may send the sequences based on a predefined sampling rate, for example, always making combination based on a feature sequence corresponding to a maximum sampling rate (M16,j in the following table); and the receiving end can correctly detect the wake-up signal regardless of whether M16,j, M8,j or M4,j is used.
When sampling is performed at a downsampling rate here, a sampling manner or an energy accumulation manner may be selected.
For example, when the sampling manner is adopted, in a case that the sampling rate is half of the original, sample values of original even-numbered or odd-numbered sampling points are sampled (as shown in Table 3). When the energy accumulation manner is used, in a case that the sampling rate is half of the original, an amplitude value of each sample point after downsampling may be determined based on a multi-amplitude value (as shown in Tables 1 and 2).
As mentioned above, the wake-up signal can be correctly detected by the receiving end regardless of whether M16,j, M8,j or M4,j is used. The following provides description by using a row with the serial number 1 in Table 1 (sampling is performed in an energy accumulation manner) as an example.
If the sending end sends a wake-up signal based on M16,j, namely, a feature sequence 1 of 0000011001101011:
Assuming that the receiving end performs monitoring based on M16,j, namely, a feature sequence 1 of 0000011001101011, it is obvious that the wake-up signal can be detected.
Assuming that the receiving end performs monitoring based on M8,j, namely, a feature sequence 2 of 00111112, every two bits in the feature sequence 1 may correspond to one bit in the feature sequence 2. For example, the first two bits 00 in the feature sequence 1 correspond to the first bit 0 in the feature sequence 2; the third and fourth bits 00 in the feature sequence 1 correspond to the second bit 0 in the feature sequence 2; the fifth and sixth bits 01 in the feature sequence 1 correspond to the third bit 1 in the feature sequence 2; . . . . In this way, the receiving end can correctly detect the wake-up signal.
Assuming that the receiving end performs monitoring based on M4,j, namely, a feature sequence 3 of 0223, every four bits in the feature sequence 1 may correspond to one bit in the feature sequence 3. For example, the first four bits 0000 in the feature sequence 1 correspond to the first bit 0 in the feature sequence 3; the fifth to eighth bits 0110 in the feature sequence 1 correspond to the second bit 2 in the feature sequence 3; the ninth to twelfth bits 0110 in the feature sequence 1 correspond to the third bit 2 in the feature sequence 3; . . . . In this way, the receiving end can correctly detect the wake-up signal.
In addition, the feature sequence set groups shown in Table 1, Table 2 or Table 3 may be predefined, for example, being specified in the protocol; or may be configured by the sending end for the receiving end. For example, the sending end may configure the feature sequence set group including multiple rows and columns shown in Table 1 for the receiving end. For another example, based on the feature value of the receiving end, the sending end merely configures a feature sequence set group of a specific row for the receiving end, where the feature sequence set group includes a plurality of feature sequences with different lengths. For example, based on the feature value 1 of the receiving end, the sending end merely configures for the receiving end a feature sequence similar to 0000011001101011; and based on 0000011001101011, the receiving end may independently determine the feature sequence 00111112 corresponding to M8,j and the feature sequence 0223 corresponding to M4,j.
As mentioned above, the wake-up signal can be correctly detected by the receiving end regardless of whether M16,j, M8,j or M4,j is used. The following provides description by using a row with the serial number 1 in Table 3 (sampling is performed in a sampling manner) as an example.
If the sending end sends a wake-up signal based on M23,j, namely, a feature sequence 1 of 00111000000101011011011:
Assuming that the receiving end performs monitoring based on M23,j, namely, a feature sequence 1 of 00111000000101011011011, it is obvious that the wake-up signal can be detected.
Assuming that the receiving end monitors a wake-up signal based on M11,j, namely, a feature sequence 2 of 01000111011, each even-numbered bit in the feature sequence 1 may correspond to one bit in the feature sequence 2. For example, the second bit in the feature sequence 1 corresponds to the first bit in the feature sequence 2; the fourth bit in the feature sequence 1 corresponds to the second bit in the feature sequence 2; . . . . In this way, the receiving end can correctly detect the wake-up signal.
Assuming that the receiving end monitors a wake-up signal based on M6,jj, namely, a feature sequence 3 of 000101, the 2nd, 6th, 10th, 14th, 18th, and 22nd bits in the feature sequence 1 correspond to the 1st, 2nd, 3rd, 4th, 5th, and 6th bits in the feature sequence 3 respectively. That is, every four bits in the feature sequence 1 correspond to one bit in the feature sequence 3. In this way, the receiving end can correctly detect the wake-up signal.
This embodiment may be combined with Embodiment 1, and this instance is mainly a detailed description of some details in Embodiment 1.
In this embodiment, the feature sequences in Mi={Mi,j|Mi,0, Mi,1, Mi,2, . . . } meet some characteristics to improve robustness of monitoring, for example, meeting the requirement of maximizing a peak-to-side lobe ratio or the requirement of minimizing a maximum sidelobe value.
For the receiving end based on signal energy monitoring, the peak-to-side lobe ratio may be obtained based on the following formula: considering one binary sequence α1, α1, . . . αN, the peak-to-side lobe ratio F may be defined as:
The method of minimizing a maximum sidelobe value is to meet a requirement that the maximum sidelobe value is the smallest.
The receiving end that performs monitoring based on signal energy may select the method of minimizing a maximum sidelobe value from all possible sequences, which may be obtained based on the following formula: considering one binary sequence α1, α1, . . . αN, the maximum sidelobe value may be defined as:
maxi|γi|, where

The feature sequence set matching with the sampling rate can be determined from the plurality of feature sequence sets, which helps the receiving end to detect the wake-up signal so as to be correctly woken up, thus improving the communication performance.
In some embodiments, in an embodiment, the feature sequence set includes a plurality of feature sequences, and each feature sequence in the plurality of feature sequences meets a requirement of maximizing a peak-to-sidelobe ratio or a requirement of minimizing a maximum sidelobe value.
