TECHNICAL FIELD

[0003] The present application belongs to the technical field of wireless communication, and specifically relates to a method and apparatus for determining a low power consumption sequence, a communication device, and a readable storage medium. BACKGROUND

[0004] In related technologies, a terminal (User Equipment, UE) opens a low power consumption receiving module to listen to a low power wake up signal (Low Power Wake Up Signal, LP-WUS, which can also be referred to as a wake up signal) and closes a main communication module in an energy saving state. When there is downlink data, the network sends the LP-WUS to the terminal. After the terminal listens to the LP-WUS through the low power consumption receiving module, the terminal triggers the main communication module to switch from off to on through a series of judgments. The LP-WUS adopts an On-Off Keying (OOK) waveform based on an Orthogonal Frequency Division Multiplexing (OFDM) architecture. The time domain signal of the traditional OOK waveform is a square wave, but after frequency domain transformation, the spectrum is a sinc function, which is easily affected by channel frequency selective fading. Therefore, in related technologies, a superposition sequence is multiplied in the time domain to ensure the frequency domain flatness of the transmitted waveform, so as to improve the reception performance. In addition, different superposition sequences can be used to carry different information (for OFDM receivers), so as to improve the transmission rate. However, how to generate the superposition sequence of the low power consumption signal has not been determined.

[0005] In related technologies, the network can send a low power synchronization signal (Low Power Synchronization Signal, LP-SS) to the terminal. The LP-SS is a periodic signal, which is used to indicate time information, for synchronization and / or frequency offset correction. The LP-SS is also an OOK waveform. How to generate the binary transmission sequence of the LP-SS has not been determined. SUMMARY

It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0040] In order to better understand the embodiments of the present application, the following technical points are introduced first.

[0041] 1.1 Low-power receiver

[0042] The low-power receiver, also known as a low-power wake-up receiver (LP-WUR) or an almost zero-power wake-up receiver (AZP-WUR). The basic working principle of the LP-WUR is that the receiving end includes a first module and a second module. As shown in FIG. 2, the first module is a main communication module for transmitting and receiving mobile communication data, and the second module is a low-power receiving module (also known as a low-power wake-up receiving module) for receiving a wake-up signal. The terminal opens the low-power receiving module to listen to the low-power wake-up signal (LP-WUS, which can also be referred to as a wake-up signal) and closes the main communication module in the energy-saving state. When there is downlink data, the network will send a wake-up signal to the terminal. After the terminal listens to the wake-up signal through the low-power receiving module, the main communication module is triggered from off to on through a series of judgments, and at this time the low-power receiving module enters the off / sleep state from the working state. The low-power wake-up receiving module can be continuously opened or intermittently opened, and can receive the low-power wake-up signal when opened.

[0043] 1.2 Low-power wake-up signal

[0044] In order to reduce the receiving activity of the terminal in the standby state, so that the radio frequency (RF) and baseband (MODEM) modules are truly closed to greatly reduce the power consumption of communication reception, a near "zero" power receiver (also known as a low-power wake-up receiver or the above low-power receiving module) can be introduced in the receiving module of the terminal to achieve this. This near "zero" power receiver does not require complex RF module signal detection (such as amplification, filtering, quantization, etc.) and modem (MODEM) signal processing, but only relies on passive matching filtering and small power signal processing.

[0045] On the base station side, by triggering the wake-up signal (LP-WUS) on demand, the near "zero" power receiver can learn the activation announcement to trigger a series of processes inside the terminal, such as turning on the radio frequency transceiver and baseband processing modules.

[0046] This wake-up signal (LP-WUS) is usually some simple on-off keying (OOK) signal, and the time domain pattern of the on-off keying signal is shown in FIG. 3, so that the receiver can learn the wake-up announcement through simple energy detection and subsequent possible sequence detection and identification processes. In addition, while the terminal turns on the low-power wake-up receiver to receive the wake-up signal, the main receiver module (i.e., the above communication module) can maintain a lower power consumption level to work, thereby achieving power saving through receiving the wake-up signal.

[0047] The reception of the low-power wake-up signal can be applied to terminals in the radio resource control idle / inactive (RRC_idle / inactive) state, and can also be applied to terminals in the radio resource control connected (RRC_connected) state, thereby achieving terminal energy saving.

[0048] 1.3 OOK waveform generation method based on OFDM architecture

[0049] The OOK waveform of the low-power signal is generated based on the orthogonal frequency division multiplexing (OFDM) architecture, and the main design idea is to not change the base station transmitting architecture in related technologies, so that appropriate data is sent on the OFDM subcarriers to make it present a square wave signal in the time domain, and the generation framework is shown in FIG. 4.

[0050] The multi-carrier OOK waveform based on the OFDM architecture can be divided into the following four types:

[0051] a) OOK-1

[0052] Please refer to FIG. 5, OOK-1 is mainly that one OFDM symbol carries one bit information, when transmitting bit1, the corresponding symbol in the frequency domain transmits data, and when transmitting bit0, the corresponding symbol in the frequency domain transmits nothing. In order to improve the transmission rate, it is necessary to increase the subcarrier space (SCS), and the data in the frequency domain can be a ZC sequence, a quadrature amplitude modulation (QAM) signal, etc. to ensure the flatness of the frequency domain signal. Assuming that no power pooling is performed between symbols, nothing is transmitted on the OFDM symbol without transmitting bits, and there will be a certain power loss.

[0053] The following is a description of OOK1:

[0054] Option OOK-1: A single bit in one OFDM symbol, the subcarriers (SCs) of the LP-WUS are:

[0055] OOK=1 indicates that all SCs are modulated.

[0056] OOK=0 indicates that all SCs are zero power (from the baseband point of view).

[0057] b) OOK-2

[0058] Please refer to FIG. 6, the OOK-2 waveform is somewhat similar to frequency-shift keying (FSK), mainly dividing multiple segments in the frequency domain, each segment carries one bit, when transmitting bit1, the corresponding segment transmits data, and when transmitting bit0, the corresponding segment transmits nothing. The data in the frequency domain can be a ZC sequence, a QAM signal, etc. to ensure the flatness of the frequency domain signal. Assuming that no power pooling is performed within the symbol, nothing is transmitted on the segment without transmitting bits, and there will be a certain power loss.

[0059] The following is a description of OOK2:

[0060] Option OOK-2: Frequency-domain parallel M-bit OOK.

[0061] The N SCs of the LP-WUS are further divided into M segments (M=2 in the figure), and there can be guard bands between and / or around them.

[0062] OOK = 1 means all SCs in the segment are modulated.

[0063] OOK = 0 means all SCs in the segment are zero power (from baseband perspective).

[0064] OOK-2 can be received using an agreed receiver architecture with OOK with parallel envelope detection.

[0065] c) OOK-3

[0066] Please refer to FIG. 7, the OOK-3 scheme is divided into multiple segments in the frequency domain, then part of the tones on each segment are modulated, and the corresponding tones are taken out by the Goertzel receiver at the receiving end and demodulated.

[0067] The following is a description for OOK3:

[0068] Option OOK-3: Multi-tone on-off keying.

[0069] The N SCs of the LP-WUS are divided into L segments (L = 2 in the figure), there are no guard-bands between segments, but there can be around.

[0070] OOK = 1 means 1 subcarrier per segment (known by the UE) is modulated, the rest of the SCs are zero power (from baseband perspective).

[0071] OOK = 0 means all SCs in all segments are zero power (from baseband perspective).

[0072] d) OOK-4

[0073] OOK-4 waveform is a flexible one among several OOK waveforms, which can control the transmission rate by adjusting the number of bits transmitted within an OFDM symbol. There are two ways to generate OOK-4, one is to use Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT-S-OFDM) to generate, and the other is to use Least Square (LS) to generate. The idea of DFT-S-OFDM is to generate the desired waveform in the time domain first, and the number of sampling points of the time domain waveform is equal to the number of WUS Resource Elements (REs). Then the frequency domain information is obtained by Discrete Fourier Transform (DFT), and then the frequency domain information is put into the corresponding WUS RE. The least square method is also to deduce the frequency domain waveform from the desired time domain waveform. It mainly uses Fast Fourier Transform (FFT) matrix and ideal time domain waveform to optimize the input frequency domain sequence X.

[0074] The following is a description of OOK4:

[0075] Option OOK-4: Convert M-bit OOK in time domain.

[0076] The N SCs of OOK-4 are generated by transformation (DFT / LS).

[0077] N' samples are generated from M bits.

[0078] Signal modification (Signal modification) can be used or not used.

[0079] Truncation or other additional modifications can be used or not used. If not used, N is the same as N'.

[0080] N' can be different from K (number of subcarriers).

[0081] A simple example: for the generation of OOK-4, assuming that one OFDM symbol transmits 4 OOK symbols (chips, or blocks), such as [1 0 1 0], that is, on off on off chips. The first step is to up-sample the information bit [1 0 10], for example, if the WUS bandwidth is 144 RE, a 144-point time-domain waveform [1(1), 1(2), …, 1(36), 0(1), …, 0(36), 1, 1(1), …, 1(36), 0(1), …, 0(36)] is generated. At this time, the time-domain signal is a square wave, and if a discrete Fourier transform (DFT) is performed on the time-domain signal, the corresponding frequency-domain signal is a sinc function, and the anti-frequency selective fading performance is poor. In related technologies, the 'on' chip of the time-domain signal can be multiplied by an overlaid sequence to change the phase, so that the frequency spectrum becomes flat. For an OOK receiver, only energy detection can detect the on off on off pattern, and the overlaid sequence cannot be detected. For an OFDM receiver, the overlaid sequence on each on chip can be correlated to obtain better reception performance or higher rate by overlaying different overlaid sequences.

[0082] It should be noted that the names of OOK-1, OOK-2, OOK-3 and OOK-4 are only for illustration, and other names can be used in the protocol.

[0083] The determination method, device and communication equipment of the low-power sequence provided in the embodiments of the present application will be described in detail in combination with the drawings and some embodiments and application scenarios.

[0084] Please refer to FIG. 9, the determination method of the low-power sequence provided in the embodiments of the present application includes:

[0085] Step S1: A first device determines a low-power sequence, wherein the low-power sequence is obtained by a first sequence and a preset sequence variation mode, and the low-power sequence is a binary transmission sequence of a low-power signal or an overlaid sequence of the low-power signal.

[0086] In the embodiments of the present application, the determination method of the binary transmission sequence of the low-power signal or the overlaid sequence is determined, so that the network side device and the terminal side have a consistent understanding of the binary transmission sequence of the low-power signal or the overlaid sequence, the detection complexity of the terminal side for the low-power signal is reduced, and the detection performance of the low-power signal is improved.

[0087] Optionally, the first device can be a network side device (such as a base station) or a terminal.

[0088] Optionally, the low-power sequence can also be referred to as a sequence of a low-power signal.

[0089] Optionally, the low-power signal can be an LP-WUS or an LP-SS. The LP-WUS is a non-periodic signal used to wake up a main communication module (or main receiver) of a terminal, and the LP-SS is a periodic signal used to indicate time information for synchronization and / or frequency offset correction of a low-power receiving module (or low-power receiver).

[0090] Optionally, if the low-power signal is an LP-WUS, the low-power sequence can be a superposition sequence of the LP-WUS.

[0091] Optionally, if the low-power signal is an LP-SS, the low-power sequence can be a binary transmission sequence of the LP-SS.

[0092] In some embodiments, optionally, the preset sequence variation mode includes at least one of sequence truncation, cyclic shift extension length, sequence zero padding, sequence repetition, cyclic shift, phase rotation, bipolar variation, and directly using the first sequence as the low-power sequence. In the embodiments of the application, at least one of the plurality of sequence variation modes can be used as needed to obtain a low-power sequence, thereby improving flexibility.

[0093] The sequence truncation refers to truncating a sequence of length X to a sequence of length Y, where X is greater than Y. The truncation can be performed by deleting part of the sequence from the front or the back of the entire sequence.

[0094] The cyclic shift extension length can be to copy the first X bits of the sequence after the last bit or copy the last X bits of the sequence before the first bit to extend the length of the sequence by X bits.

[0095] The sequence zero padding can be to pad X zeros before the first bit (i.e., the beginning of the sequence) and / or after the last bit (i.e., the end of the sequence) to extend the length of the sequence by X bits.

[0096] The sequence repetition can be to repeat the entire sequence X times, for example, to repeat the sequence [a b c d] as [a b c d a b c d], or to repeat each bit in the sequence X times, for example, to repeat the sequence [a b c d] as [a a b b c c d d].

[0097] The cyclic shift (CS) can be to shift the first X bits of the sequence to after the last bit or to shift the last X bits of the sequence to before the first bit. After the cyclic shift, the length of the sequence remains unchanged.

[0098] The phase rotation is to multiply the sequence by a phase to obtain a new sequence.

[0099] The bipolar change refers to changing the polarity of the values in the sequence, for example, changing 0 to -1 or 0 to 1 or 1 to -1.

[0100] Optionally, the preset sequence change mode is configured by a network side device or predefined by a protocol.

[0101] In some embodiments, optionally, the first sequence is determined by first information, and the first information includes at least one of the following: a length of the low-power consumption sequence, a resource mapping manner of the low-power consumption sequence, a type of the first sequence, a length of the first sequence, and a sequence root of the first sequence.

[0102] The resource mapping manner of the low-power consumption sequence can include whether the low-power consumption sequence is time domain mapping or frequency domain mapping. If it is time domain mapping, the resource mapping manner can further indicate a time domain before DFT mapping. If it is frequency domain mapping, the resource mapping manner can further indicate a frequency domain before Inverse Fast Fourier Transform (IFFT) mapping.

[0103] Optionally, the first information is configured by a network side device or predefined by a protocol.

[0104] In some embodiments, optionally, at least one of the length of the low-power consumption sequence and the resource mapping manner of the low-power consumption sequence is determined by second information, and the second information includes at least one of the following: a transmission rate of the low-power consumption signal, a number of OOK chips of the low-power consumption signal in one OFDM symbol, a bandwidth of the low-power consumption signal, a subcarrier spacing, a generation manner of the low-power consumption signal, and a waveform of the low-power consumption signal.

[0105] The generation manner of the low-power consumption signal can be, for example, whether to contain DFT (containing DFT can be understood as OOK-4 waveform).

[0106] The waveform of the low-power consumption signal can be, for example, OOK-1 or OOK-4.

[0107] In some embodiments, optionally, the type of the first sequence is determined by third information, and the third information includes at least one of the following: a transmission rate of the low-power consumption signal, a number of OOK chips of the low-power consumption signal in one OFDM symbol, a generation manner of the low-power consumption signal, and a waveform of the low-power consumption signal.

[0108] In some embodiments, optionally, the type of the first sequence comprises at least one of the following: a ZC sequence, an M sequence, a Gold sequence, a Secondary Synchronization Signal (SSS) sequence, a Primary Synchronization Signal (PSS) sequence, a Computer Search sequence. In the embodiments of the present application, the type of the first sequence is various, and at least one type can be selected as needed to obtain a low-power consumption sequence, thereby improving flexibility.

[0109] In some embodiments, optionally, when the type of the first sequence is a ZC sequence, the length of the first sequence is a prime number closest to the length of the low-power consumption sequence (a prime number refers to a natural number greater than 1, which has no other factors except 1 and itself). For example, the length of the low-power consumption sequence is 66, and a first sequence with a length of 65 can be selected.

[0110] In some embodiments, optionally, when the type of the first sequence is a ZC sequence, the sequence roots of the first sequence comprise at least one combination pair in a sequence root combination pair, and each combination pair comprises two sequence root values whose sum is equal to the length of the first sequence.

[0111] Because the length of the first sequence and the sequence roots are not co-prime, the autocorrelation of the ZC sequence will be poor, and when the sequence roots of two ZC sequences are not co-prime, the cross-correlation of the two ZC sequences will be poor. Therefore, in some embodiments, optionally, the sequence root values in the combination pair are co-prime with the length of the first sequence, and the two sequence root values in each combination pair are co-prime, so as to improve the autocorrelation of the ZC sequence and the cross-correlation of the two ZC sequences.

[0112] In some embodiments, optionally, the length of the first sequence is 33, and the sequence root combination of the first sequence comprises at least one of the following: {1, 32}, {2, 31}, {4, 29}, {5, 28}, {7, 26}, {8, 25}, {10, 23}, {13, 20}, {14, 19}, {16, 17};

[0113] The length of the first sequence is 33, and the sequence root combination of the first sequence can be represented by the following table:

[0114] In some embodiments, optionally, the length of the first sequence is 31, and the sequence root combination of the first sequence comprises at least one of the following: {1, 30}, {2, 29}, {3, 28}, {4, 27}, {5, 26}, {6, 25}, {7, 24}, {8, 23}, {9, 22}, {10, 21}, {11, 20}, {12, 19}, {13, 18}, {14, 17}, {15, 16};

[0230] The determination method of the low-power sequence of the embodiments of the present application will be described below by way of example in combination with specific application scenarios.

[0231] Embodiment one of the present application:

[0232] In this embodiment, the low-power signal is an LP-WUS, which is transmitted using an OOK-4 waveform, the OOK-4 waveform is generated using a DFT-S-OFDM manner, the low-power sequence is a superposition sequence, and a first sequence used to generate the superposition sequence is a ZC sequence.

[0233] For example, it is assumed that a WUS RE (i.e., the bandwidth of a low-power signal) = 132, one OFDM symbol transmits four OOK chips, for example, [1 0 1 0], i.e., four chips of on off on off, the OOK-4 waveform is generated using a DFT-S-OFDM manner, and the resource mapping manner of the superposition sequence is the time domain, and the on chip in the time domain needs to be generated into a superposition sequence of a corresponding size. The base station or the terminal obtains first information such as the length of the superposition sequence, the resource mapping manner of the superposition sequence, the number of superposition sequences, the type of the first sequence, the length of the first sequence, and the sequence root index according to configuration information, determines the first sequence according to the first information, and generates the superposition sequence according to the first sequence.

[0234] The method of generating the superposition sequence by the base station or the terminal will be described in detail below.

[0235] 1: determine the length of the superposition sequence and the resource mapping manner of the superposition sequence.

[0236] The base station or the terminal can determine the length of the superposition sequence and the resource mapping manner of the superposition sequence (time domain mapping, for example, mapping to the time domain before DFT, or frequency domain mapping, for example, mapping to the frequency domain before Inverse Fast Fourier Transform (IFFT)) according to the second information. The second information includes at least one of the following: the transmission rate of the low-power signal, the number M of OOK chips within one OFDM symbol, the bandwidth of the low-power signal, the subcarrier spacing (SCS), the generation manner of the low-power signal (for example, whether to contain DFT, which can be understood as whether it is an OOK-4 waveform), and the transmission waveform of the low-power signal (such as OOK-4).

[0237] The base station can also directly indicate the resource mapping manner of the superposition sequence or the length of the superposition sequence by signaling. For example, the base station indicates that the resource mapping manner of the superposition sequence is time domain mapping, upsampling on the information bit [1 0 1 0] (which can indicate that the number M of OOK chips within one OFDM symbol is 4), and the upsampling is 132 samples (the bandwidth of the low-power signal = 132 RE), so the sample point size of each OOK chip can be calculated as 132 / 4 = 33 (that is, the length of each on chip is calculated). If the superposition sequence is superimposed on each on chip, the length of the superposition sequence = 33; if the superposition sequence is superimposed on all on chips in one OFDM symbol, the length of the superposition sequence = 66; if the superposition sequence is superimposed on all chips in one OFDM symbol, the length of the superposition sequence = 132.

[0238] 2: determine the type of the first sequence, the length of the first sequence, and the sequence root index.

[0239] Optionally, the type of the first sequence can be predefined by a protocol or configured by a network.

[0240] Optionally, the type of the first sequence can also be determined by third information, which includes at least one of the following: the transmission rate of the low-power signal, the number of OOK chips of the low-power signal within one OFDM symbol, the generation manner of the low-power signal, and the waveform of the low-power signal. For example, if the number M of OOK chips of the low-power signal within one OFDM symbol is 1, the first sequence is M or a gold sequence. If M > 1, the first sequence is a ZC sequence.

[0241] If the type of the first sequence predefined by the protocol or configured by the network is ZC sequence, if the length of the first sequence indicated by the base station is 33, the sequence root table corresponding to the length N = 33 of the ZC sequence is queried, and the specific sequence root is determined according to the sequence root index i, for example, the sequence root index i = 2, and the sequence root u = {4, 29} of the ZC sequence is determined. It should be noted that in the table of the length of the ZC sequence = 33, the sequence roots less than 33 are not listed, but some sequence roots are removed, because when the length of the first sequence and the sequence root are not co-prime, the autocorrelation of the ZC sequence will be poor, and when the sequence roots of two ZC sequences are not co-prime, the cross-correlation of the two ZC sequences will be poor, so when the length of the ZC sequence is 33 = 3 * 11, the sequence roots with common factors of 3 and 11 are removed.

[0242] In some embodiments, if the length of the indicated superposition sequence is 66 and the length of the first sequence is 65 (the length of the first sequence is less than 66 in the case that the length of the superposition sequence is greater than the length of the first sequence, and the length of the first sequence can also be other lengths less than 66), the sequence root table corresponding to the length N = 65 of the ZC sequence is determined, and the specific sequence root is determined according to the sequence root index i.

[0243] Based on the determined sequence root, the first sequence can be generated according to the generation formula of the ZC sequence:

[0244] wherein, ZC u (i) is the first sequence, u is the sequence root, and N is the length of the ZC sequence.

[0245] 3: Determine a preset change mode.

[0246] In some embodiments, when the length of the superposition sequence is equal to the length of the first sequence, the generated first sequence can be directly used as the superposition sequence.

[0247] In some embodiments, when the length of the superposition sequence is greater than the length of the first sequence, the generated first sequence can be extended to the appropriate superposition sequence by cyclic shift, for example, the length of the first sequence is 65 and the length of the superposition sequence is 66, the first bit of the first sequence can be cyclically shifted to the last bit, and the length is changed to 66.

[0248] In some embodiments, for example, the length of the first sequence is 33 and the length of the superposition sequence is 66, the first sequence can be repeated to change the length to 66, and there are two operation modes for the repetition, for example, mode 1: the sequence [a b c d] is repeated as [a a b b c c d d], and mode 2: the sequence [a b c d] is repeated as [a b c d a b c d].

[0249] In some embodiments, different superposition sequences can also be generated according to the number of superposition sequences required.

[0250] If multiple different superposition sequences are to be generated, the different superposition sequences represent different information, and the different superposition sequences can be determined in the following ways:

[0251] a) In the process of generating different superposition sequences, different sequence roots are used to generate first sequences, for example, the base station or the UE determines the first sequence root u = 4 used to generate the first sequence according to the sequence root index i, and determines the second sequence root u = 29 in the combined pair as the other sequence root used to generate the first sequence;

[0252] b) The generated superposition sequences are cyclically shifted, for example, a 16-bit cyclic shift is performed on a superposition sequence with a length of 33;

[0253] c) The first sequences are cyclically shifted, a 32-bit cyclic shift is performed on a first sequence with a length of 65 to obtain a new first sequence, and different superposition sequences are generated according to the two first sequences;

[0254] d) If multiple superposition sequences are required, the base station or the UE can generate multiple first sequences according to different sequence roots + different cyclic shifts, and the size and number of cyclic shifts are predefined by the protocol or configured by the network. For example, a first sequence is generated using the sequence root corresponding to the first index, and different cyclic shifts are performed on the first sequence to obtain different low-power consumption sequences. If the number of low-power consumption sequences obtained is not enough, a new first sequence is generated using the sequence root corresponding to the second index, and different cyclic shifts are performed on the new first sequence to obtain different low-power consumption sequences until the number of low-power consumption sequences meets the requirement. Alternatively, the second index is the first index plus 1, of course, the second index can also be determined in other ways, which are not limited by the present application. For example, if 4 superposition sequences (with a length of 33) are to be generated, the network indicates the sequence root u = 4, the number of cyclic shifts is 2, and the cyclic shift size is CS = 0 and CS = 16. First, 2 superposition sequences are generated using u = 4, CS = 0 and u = 4, CS = 16, then another sequence root u = 29 is determined according to the combined pair of u = 4, and u = 29, CS = 0 and u = 29, CS = 16 are combined with the cyclic shift to generate another 2 superposition sequences.

[0255] It should be noted that the above three processes for determining the related parameters do not have a specific order, i.e., the base station or the UE does not have to determine the parameters in a specific order. Embodiment two of the present application:

[0256] In this embodiment, the low-power signal is an LP-WUS, transmitted using an OOK-1 waveform, and the low-power sequence is a superposition sequence. The first sequence used to generate the superposition sequence is a ZC sequence.

[0257] The base station or terminal determines the length of the superposition sequence and the resource mapping manner of the superposition sequence, the number of superposition sequences, the type of the first sequence, the sequence length of the first sequence, the sequence root index, and other first information according to the configuration information, determines the first sequence according to the first information, and generates the superposition sequence according to the first sequence.

[0258] The method for the base station or terminal to generate the superposition sequence is described in detail below.

[0259] 1. Determine the length of the superposition sequence and the resource mapping manner of the superposition sequence.

[0260] Since the low-power signal in this embodiment uses an OOK-1 waveform, the indicated resource mapping manner of the superposition sequence is the frequency domain, and the length of the superposition sequence is the same size as the bandwidth. Assuming that the WUS RE (i.e., the bandwidth of the low-power signal) = 132, one OFDM symbol transmits one OOK chip (M = 1) at this time, and the length of the superposition sequence = 132.

[0261] 2. Determine the type of the first sequence, the length of the first sequence, and the sequence root index.

[0262] Assuming that the indicated type of the first sequence is a ZC sequence and the indicated length of the first sequence is N = 131, the ZC sequence corresponding sequence root table will be determined according to the length of the first sequence at this time, and the specific sequence root will be determined according to the indicated sequence root index i, for example, the sequence root u = {2, 129} of the ZC sequence is obtained by querying the table when the indicated sequence root index i = 1, and the corresponding first sequence can be generated according to the generation formula of the ZC sequence.

[0263] Assuming that the indicated length of the first sequence is N = 127, the ZC sequence corresponding sequence root table will be determined according to the length of the first sequence at this time, and the specific sequence root will be determined according to the indicated sequence root index i, for example, the sequence root u = {2, 125} of the ZC sequence when the sequence root index i = 1.

[0264] The corresponding first sequence can be generated according to the formula of the ZC sequence:

[0265] wherein ZC u (i) is the first sequence, u is the sequence root, and N is the length of the ZC sequence.

[0266] 3. Determine the preset change manner.

[0267] In some embodiments, when the length of the superposition sequence is greater than the length of the first sequence, the generated first sequence can be extended in length by cyclic shift to generate a proper superposition sequence, for example, the length of the first sequence is 131 and the length of the superposition sequence is 132, the first sequence can be cyclically shifted to the last bit of the first bit of the sequence to change to 132 long.

[0268] In some embodiments, the superposition sequence of 132 long can also be generated by the operation of cyclic shift extension and 0 padding, for example, the first sequence of 127 long is first cyclically shifted to 128 long, and then 0 is padded at the beginning and end of 2 to change to a superposition sequence of 132 long.

[0269] In some embodiments, different superposition sequences can also be generated according to the number of superposition sequences required.

[0270] Suppose multiple different superposition sequences are to be generated, different superposition sequences represent different information, and different superposition sequences can be determined in the following ways:

[0271] a) Different sequence roots are used to generate the first sequence in the process of generating different superposition sequences, for example, the base station or UE determines the first sequence root u=129 used to generate the first sequence according to the sequence root index i, and determines the second sequence root u=2 used to generate the first sequence as another sequence root in the combined pair;

[0272] b) Cyclic shift is performed on the generated superposition sequence, for example, cyclic shift of 66 bits is performed on the superposition sequence of 132 long;

[0273] c) Cyclic shift is performed on the first sequence, cyclic shift of 66 bits is performed on the first sequence of 131 long to obtain a new first sequence, and different superposition sequences are generated according to the two first sequences;

[0274] d) Phase rotation is performed on the generated superposition sequence, for example, a new superposition sequence is obtained by multiplying a phase on the superposition sequence of 132 long;

[0275] e) If multiple superposition sequences are needed, the base station or UE can compose multiple first sequences according to different sequence roots + different cyclic shifts, the size and number of cyclic shifts are predefined by the protocol or configured by the network. For example, first, a first sequence is generated by using a sequence root corresponding to a first index, different low-power consumption sequences are obtained by performing different cyclic shifts on the first sequence, if the number of obtained low-power consumption sequences is not enough, new first sequences are generated by using a sequence root corresponding to a second index, different low-power consumption sequences are obtained by performing different cyclic shifts on the new first sequences, until the number of low-power consumption sequences meets the requirement. Alternatively, the second index is the first index plus 1, of course, the second index can also be determined in other ways, which is not limited in the application. For example, if 4 superposition sequences (length 132) are to be generated, the network indicates that the sequence root u = 2, the number of cyclic shifts is 4, and the size of the cyclic shift is CS = 0, CS = 33, CS = 66 and CS = 99, at this time, 4 superposition sequences can be generated by (u = 2, CS = 0), (u = 2, CS = 33), (u = 2, CS = 66) and (u = 2, CS = 66), which already meets the number requirement of superposition sequences.

[0276] It should be noted that the above three processes of determining the three related parameters 1, 2 and 3 do not have a sequence limitation, that is, the base station or UE does not limit the order of determining the above parameters.

[0277] Embodiment three of the application:

[0278] In this embodiment, the low-power consumption signal is LP-WUS, and the first sequence used to generate the superposition sequence is the PSS or SSS sequence.

[0279] Suppose the length of the superposition sequence is 33, the first sequence is the PSS sequence or the SSS sequence, and the length of the first sequence N = 127. At this time, the length of the first sequence is greater than the length of the superposition sequence, if the corresponding superposition sequence is to be generated, the sequence truncation operation needs to be performed on the first sequence, for example, the superposition sequence is generated by intercepting the numbers of 0-32 of the PSS sequence.

[0280] Suppose the length of the superposition sequence is 128, if the corresponding superposition sequence is to be generated, the cyclic shift length extension operation or the 0 padding operation needs to be performed on the first sequence to generate the 128-length superposition sequence.

[0281] For the PSS sequence, there are only 3 different sequences, the sequence root, that is, the PSS generation formula in can be configured by the network or predefined by the protocol.

[0282] For the SSS sequence, different first sequences can be generated according to and . and The network configuration or protocol can be predefined.

[0283] The generation formula of the PSS sequence can be as follows:

[0284] d PSS (n) = 1 - 2x(m), where,

[0285] wherein d PSS (n) is the PSS sequence; x(i+7) = (x(i+4) + x(i)) mod 2; [x(6) x(5) x(4) x(3) x(2) x(1) x(0)] = [1 1 1 0 1 1 0].

[0286] The generation formula of the SSS sequence can be as follows: d SSS (n) = [1 - 2x0((n+m0) mod 127)] [1 - 2x1((n+m1) mod 127)]

[0287] wherein d SSS (n) is the SSS sequence; x0(i+7) = (x0(i+4) + x0(i)) mod 2 x1(i+7) = (x1(i+1) + x1(i)) mod 2; [x0(6) x0(5) x0(4) x0(3) x0(2) x0(1) x0(0)] = [0 0 0 0 0 0 1] [x1(6) x1(5) x1(4) x1(3) x1(2) x1(1) x1(0)] = [0 0 0 0 0 0 1].

[0288] Suppose that multiple different Zadoff-Chu sequences are to be generated, and the different Zadoff-Chu sequences represent different information. The different Zadoff-Chu sequences can be determined in the following manner:

[0289] a) Different cyclic shifts and sequence truncations are performed on the first sequence, for example, different cyclic shifts of size CS = 0 / 32 / 64 / 96 are performed on a PSS or SSS sequence of length 127, and then sequence truncation is performed on the cyclically shifted PSS or SSS sequence, for example, the numbers from 0 to 32 are taken, to obtain multiple first sequences, and the different Zadoff-Chu sequences are obtained according to the multiple first sequences.

[0290] b) Different Zadoff-Chu sequences are generated by performing cyclic shifts on the Zadoff-Chu sequence, for example, a cyclic shift of 16 bits is performed on a Zadoff-Chu sequence of length 33 that has already been generated, to obtain different Zadoff-Chu sequences.

[0293] Embodiment four of the present application:

[0294] In this embodiment, the low-power signal is LP-WUS, and the first sequence used to generate the superposition sequence is an M sequence or a gold sequence.

[0295] Suppose that if the first sequence is an M sequence, the length of the superposition sequence M = 33, the length of the M sequence closest to the length of the superposition sequence is selected as the length of the first sequence, the length of the first sequence is 31, the polynomial order n = 5, and there are 6 candidate polynomials, which are [x^5+x^2+1,x^5+x^3+1,x^5+x^3+x^2+x^1+1,x^5+x^4+x^2+x^1+1,x^5+x^4+x.^3+x^1+1,x^5+x^4+x^3+x^2+1]. The initial state of the polynomial is the default value, for example, the default value is 1, and the 31-long M sequence can be generated according to the above information, the first and second bits can be extended to the tail by cyclic shift, or the M sequence can be changed to 33 long by filling 0, and then the bipolar change is used to change the 0 and 1 bits to -1 and 1, at this time a complete superposition sequence is generated.

[0296] Similarly, if the first sequence is a gold sequence, the corresponding sequence root is c init Different c init will generate different first sequences, and the length of the gold sequence is predefined by the network configuration or the protocol (for example, the default c init = 1), and suppose that the length of the first sequence is greater than the length of the superposition sequence, then the sequence truncation operation needs to be performed on the first sequence, and the truncation start position can be predefined by the network configuration or the protocol. For example, a 128-long gold sequence is generated, and the numbers from 32 to 64 bits are truncated.

[0297] The generation formula of the gold sequence can be as follows: c(n) = (x1(n+N C + x2(n+N Cx2(n+31) = (x2(n+3) + x2(n+2) + x2(n+1) + x2(n)) mod 2

[0298] where c(n) is a Gold sequence, n = 0, 1,..., M PN -1, N C = 1600, the first m-sequence x1(n) should be initialized as x1(0) = 1, x1(n) = 0, n = 1, 2,..., 30, and the initialization of the second m-sequence x2(n) is determined by The value depends on the application of the sequence.

[0299] Suppose that multiple different superposition sequences are to be generated, different superposition sequences represent different information, and different superposition sequences can be determined in the following ways:

[0300] a) Different cyclic shifts are performed on the first sequence, for example, for an m-sequence, different assignments can be made to the initial state to control the cyclic shift of the first sequence, or the generated first sequence is cyclically shifted, both of which can be used;

[0301] b) The superposition sequence is cyclically shifted to generate different superposition sequences, for example, a 33-bit superposition sequence is generated, and a 16-bit cyclic shift is performed to obtain different superposition sequences.

[0302] c) Different sequence truncations are performed on the first sequence to generate different superposition sequences, assuming that the generated M or Gold sequence is longer than the superposition sequence, this scheme can be used, and the starting position of the sequence truncation can be configured by the network or predefined by the protocol.

[0303] d) Different polynomials or c init Different first sequences are generated, and different superposition sequences are generated according to different first sequences, for an m-sequence, different first sequences can be generated by different polynomials, and different polynomial tables can be as shown in Table 10; for a Gold sequence, different first sequences can be generated by different c init .

[0305] Embodiment five of the present application:

[0306] In this embodiment, the low-power signal is an LP-SS, the first sequence is a Computer Search sequence, and the gold sequence or m-sequence.

[0307] Low Power Synchronization Signal (LP-SS) is mainly used for synchronization of signals, which is sent by base station to terminal. The binary transmission sequence of LP-SS searched by terminal should ensure good autocorrelation, and the cross-correlation of LP-SS sequence of other cells should also be good. The indexes of autocorrelation mainly include: minimizing side lobe (or trough), and / or minimizing secondary peak in detection window, and the indexes of cross-correlation include: minimizing maximum peak in detection window. When searching LP-SS sequence, it is also necessary to ensure the balance of 0 and 1 in symbol or the number of 0 or 1 in each symbol (for the transmission scheme of OOK chip number M>1 of low power signal in one OFDM symbol), if it is M=1 transmission scheme, it is necessary to ensure the balance of 0 and 1 in the whole sequence. According to the above criteria, LP-SS sequence is searched to obtain sequence group meeting synchronization performance, each sequence group contains four sequences (Seq) (corresponding to four cells respectively), and different sequences are used for adjacent cells of target cell.

[0308] The LP-SS sequence can be Computer Search sequence, gold sequence or M sequence.

[0309] If the LP-SS sequence is Computer Search sequence, the terminal needs to traverse all possible sequence groups, and then search according to the above index requirements.

[0310] For example, the length of LP-SS sequence is 8 (applicable to M=1), and the searched sequence group can be shown in Table 11.

[0311] Table 11

[0312] For example, the length of LP-SS sequence is 12 (applicable to M=2 or M=1 or M=4), and the searched sequence group can be shown in Table 12.

[0313] Table 12

[0314] For example, the length of LP-SS sequence is 8 (applicable to M=2 or M=1 or M=4), and the searched sequence group can be shown in Table 13.

[0315] Table 13

[0316] For example, the length of LP-SS sequence is 16 (applicable to M=1 or M=4), and the searched sequence group can be shown in Table 14.

[0317] Table 14

[0318] For example, the length of LP-SS sequence is 28 (M=1 or M=4 is applicable), the searched sequence groups can be shown in Table 15:

[0319] Table 15

[0320] For example, the length of LP-SS sequence is 32 (M=1 or M=4 is applicable), the searched sequence groups can be shown in Table 16:

[0321] Table 16

[0322] In some embodiments, the sequence group of low power consumption sequence can be determined according to the first condition, assuming that the first condition includes: the length of LP-SS sequence is 32, M=1, then the sequence group of low power consumption sequence can be one of the sequence groups in Table 16.

[0323] In some embodiments, the first condition can further include: the time accuracy required by low power consumption sequence, if the required time accuracy is high, a sequence group with larger sequence length can be selected, if the required time accuracy is low, a sequence group with smaller sequence length can be selected.

[0324] If the LP-SS sequence is gold sequence, the corresponding LP-SS sequence can be generated according to its C init and the length of gold sequence (the length of gold sequence is larger than the length of LP-SS sequence), for example, the length of LP-SS sequence is 16, then a 128-length gold sequence can be generated, and the required LP-SS sequence can be obtained by cyclic shift, truncation and / or different C init If it is M sequence, different M sequences can be generated according to different orders and polynomials, and then the required LP-SS sequence can be obtained by sequence truncation.

[0325] In some embodiments, the length of LP-SS sequence and / or the sequence group number and / or the cell number (assuming that the sequence type has been defined by the protocol) can be obtained according to network configuration or protocol predefinition, so as to select the sequence group, and then obtain the target LP-SS sequence from the sequence group; or the type of first sequence, for example, gold sequence, can be obtained according to network configuration or protocol predefinition, then the gold sequence can be generated according to the length of gold sequence, and the LP-SS sequence meeting the length requirement of LP-SS sequence can be obtained by cyclic shift and sequence truncation.

[0326] Suppose the LP-SS sequence sent by the base station is [1 0 1 0 1 0 1 0], and the receiving end changes the local LP-SS sequence to [1 -1 1 -1 1 -1 1 -1] when generating the local LP-SS sequence, so that the wave trough beside the maximum wave peak becomes smaller.

[0327] Suppose the sending sequence is [1 0 1 0 1 0 1 0], and the local LP-SS sequence generated by the receiving end is [1 0 1 0 1 0 1 0], and the correlation result is shown in FIG. 10.

[0328] Suppose the LP-SS sequence sent by the base station is [1 0 1 0 1 0 1 0], and the local LP-SS sequence generated by the receiving end is [1 -1 1 -1 1 -1 1 -1], and the correlation result is shown in FIG. 11.

[0329] As can be seen from the two autocorrelation results, when the local LP-SS sequence becomes [1, -1], the maximum wave peak of the autocorrelation result does not change, but the wave trough beside the maximum wave peak changes from 0 to [-4, -3], which is conducive to the synchronization detection of the sequence.
