Description

Information acquisition and transmission methods, devices, terminals and network equipment

[0001] This disclosure claims priority to Chinese Patent Application No. 202510108115.0, filed with the Chinese Patent Office on January 23, 2025, entitled "Information Acquisition, Transmission Method, Apparatus, Terminal and Network Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to an information acquisition and transmission method, apparatus, terminal and network equipment. Background Technology

[0003] The research on terminal energy saving proposes the concept of a Low Power Wake-Up Receiver (LP-WUR), which further reduces terminal energy consumption based on existing energy-saving technologies. When neither the base station nor the terminal is transmitting services, the power-intensive main radio (MR) is turned off, while the LP-WUR is activated to receive signals from the base station. When services are being transmitted, the base station activates the MR via relevant signals to complete the transmission. This significantly reduces terminal power consumption when there is no service transmission.

[0004] During LP-WUR activation, the terminal, in a low-power state, can receive at least one of the following signals carried by signals generated from at least one of the following waveforms: On-Off Keying (OOK), Frequency-Shift Keying (FSK), Quadrature Phase Shift Keying (QPSK), Orthogonal Frequency Division Multiplexing (OFDM), Code Division Multiplexing (CDM), Time Division Multiplexing (TDM), and Non-Orthogonal Multiple Access (NOMA).

Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0050] The following is a brief explanation of the relevant concepts mentioned in this disclosure.

[0051] I. Generation of Low-Power Wake-up Signal (LP-WUS)

[0052] The LP-WUS research project focuses on methods for generating LP-WUS and Low Power Synchronizing (LP-SS) signals based on OFDM waveforms superimposed with On-Off Keying (OOK) waveforms. The OOK waveform requires standardization of OOK-1 and OOK-4 waveforms. The OOK waveform carries wake-up indication information for OOK-based LP-WUS. Whether the OFDM sequence can carry OFDM-based LP-WUS wake-up indication information, and if so, how, requires further investigation; no conclusion has been reached at the conference.

[0053] OOK-1 waveform: One OFDM symbol corresponds to a single-bit. The method of mapping LP-WUS to a subcarrier (SC) is as follows:

[0054] OOK=1 means that all SCs are used for modulation;

[0055] OOK=0 means that all SCs have zero power (from the baseband perspective).

[0056] OOK-4 waveform: M-bit OOK-4 is generated in the time domain. The signal needs to undergo DFT / least square transformation before being mapped to N SCs. The OFDM sequence carrying part or all of the LP-WUS indication information is superimposed at the position where the bit value is 1.

[0057] II. The process of generating LP-WUS signals based on OOK-1 / 4 waveforms and OFDM waveforms

[0058] The LP-WUS signal generation sequence is generated by superimposing OFDM waveforms at the OOK ON bit positions. The jointly generated sequence is mapped onto the time-frequency resource positions and then transmitted after undergoing an Inverse Fast Fourier Transform (IFFT). OOK-based LP-WUS acquires the information carried by LP-WUS based on the ON / OFF pattern of the OOK symbols; OFDM-based LP-WUS acquires the information carried by LP-WUS based on the OFDM waveform sequence superimposed at the resource positions mapped by the OOK ON symbols.

[0059] III. Wake-up Signal Generation Method

[0060] In Radio Resource Control (RRC) Idle / Inactive (RRC_IDLE / INACTIVE) mode, the standardized DCI 2_7 is a downlink control signal generated based on OFDM signals. The wake-up indication field in this signal uses a bitmap to simultaneously indicate whether multiple terminal groups are awake and receiving paging messages at the Paging Opportunity (PO) location. In RRC_CONNECTED mode, the standardized DCI 2_6 is also a downlink control signal generated based on OFDM signals. The wake-up indication field in this signal uses a bitmap to simultaneously indicate whether multiple terminals are in Discontinuous Reception (DRX) active state to receive downlink data.

[0061] In New Radio (NR) systems, there are no sequence generation rules based on the joint generation of OOK and OFDM waveforms. Furthermore, the information carrying capacity of the joint waveform is far less than that based on the Physical downlink control channel (PDCCH) and NR sequences (Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), and Channel State Information Reference Signal (CSI-RS)). The following issues need to be considered when designing the aforementioned sequence generation rules:

[0062] 1) LP-WUS: When different listening opportunity (MO) groups transmit wake-up information of different subgroups under a low-power wake-up signal receiving opportunity (LO), the OFDM sequence carries the information of the MO group under LO, as well as the subgroup information associated with the MO group; the mapping relationship between this information and the sequence generator polynomial needs to be established. Based on a specific OFDM sequence generator polynomial, it is necessary to study how to design the parameters that carry the information and the values ​​of the parameters.

[0063] 2) LP-SS: LP-SS is used by LP-WUR to obtain the time and frequency synchronization information of the received LP-WUS. The LP-SS based on the joint waveform carries 2 bits of cell identifier (Cell ID) information. How to design the sequence generator polynomial and how to design the parameters of the generator polynomial to carry part of the Cell ID information need to be studied.

[0064] To address the above issues, this disclosure proposes a sequence generation method and a sequence generation related parameter determination method applicable to low-power wake-up signals and low-power synchronization signals, which can carry at least one of wake-up information, synchronization information, and cell index information.

[0065] The embodiments of this disclosure are described below with reference to the accompanying drawings. The information acquisition, transmission methods, apparatus, terminals, and network devices provided in the embodiments of this disclosure can be applied to wireless communication systems. This wireless communication system can be a system employing fifth-generation (5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art will understand that the 5G NR system is merely an example and not a limitation.

[0066] In some embodiments, the structure of a network system to which this disclosure applies includes a user terminal and a base station. The user terminal can be user equipment (UE), such as a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), or wearable device. It should be noted that this disclosure does not limit the specific type of user terminal. The base station can be a 5G or later version base station (e.g., gNB, 5G NR NB, 6th Generation (6G) base station), or a base station in other communication systems, also referred to as a node B. It should be noted that this disclosure uses a 5G base station as an example only, but does not limit the specific type of base station.

[0067] This disclosure provides an information acquisition and transmission method, apparatus, terminal, and network device to accurately acquire at least one of wake-up information, synchronization information, and cell index information.

[0068] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0069] As shown in Figure 1, this embodiment of the present disclosure provides an information acquisition method, executed by a terminal, including:

[0070] Step S101: Determine the generation sequence of the first signal, the generation sequence including a first sequence generated from a first waveform and / or a second sequence generated from a second waveform;

[0071] Step S102: According to the generated sequence, receive the second sequence and / or the first sequence in the first signal;

[0072] Step S103: Obtain target information according to the second sequence and / or the first sequence, wherein the target information includes at least one of the following: wake-up information, synchronization information, and cell index information;

[0073] The first waveform includes at least one of the following: OOK waveform, FSK waveform, QPSK waveform; the second waveform includes at least one of the following: OFDM waveform, CDM waveform, TDM waveform, NOMA waveform.

[0074] It should be noted that in this embodiment, by receiving a second sequence and / or a first sequence in the first signal according to the determined generation sequence of the first signal, at least one of the wake-up information, synchronization information and cell index information can be obtained; thereby, at least one of the wake-up information, synchronization information and cell index information can be accurately obtained, ensuring communication reliability.

[0075] In some embodiments, the first signal can be understood as a signal carrying target information.

[0076] In some embodiments, under one implementation, the first signal in this disclosure embodiment may be LP-WUS for waking up the terminal, or LP-SS for synchronization and / or radio resource management (RRM) measurement.

[0077] In some embodiments, in one implementation, the first signal carries N1 second sequences, and the N1 second sequences are carried at positions where the bits carried by the first sequence are of the first value;

[0078] Wherein, N1 is an integer greater than or equal to 1; N1 second sequences consist of at least one second sequence that transmits target information of different terminals or terminal groups, and / or at least one second sequence that transmits target information of the same terminal or terminal group.

[0079] It should be noted that, typically, the bits carried by the first sequence are 1 or 0, or 1 or -1. However, in this embodiment, the first value refers to a value of 1, meaning that N1 second sequences are carried at the positions where the bits carried by the first sequence are 1. The N1 second sequences transmit target information of the same terminal or terminal group, and / or transmit target information of different terminals or terminal groups.

[0080] In some embodiments, under one implementation, N1 satisfies at least one of A11-A13:

[0081] A11 and N1 represent the number of times a second sequence is repeatedly transmitted on a first signal;

[0082] In some embodiments, this situation can be understood as N1 second sequences transmitting the target information of the same terminal or terminal group, or it can be understood as N1 second sequences being repeatedly transmitted on the first signal.

[0083] In some embodiments, N1 can be determined based on at least one of the following: network device configuration, protocol agreement, information of a first sequence generated by a first waveform, the number of candidate second sequences representing an enabled resource location association in the symbols corresponding to the first waveform, the number of terminals or terminal groups associated with a first signal eavesdropping opportunity (MO), the number of terminals or terminal groups indicated by a first signal, and information of the second sequence. That is, N1 can be determined by network device configuration and / or protocol agreement, or N1 can be determined by at least one of the following: information of a first sequence generated by a terminal based on the first waveform, the number of candidate second sequences representing an enabled resource location association in the symbols corresponding to the first waveform, the number of terminals or terminal groups associated with a first signal eavesdropping opportunity (MO), the number of terminals or terminal groups indicated by a first signal, and information of the second sequence.

[0084] In some embodiments, the information of the first sequence mentioned in this disclosure includes at least one of the following: the number of bits of the first sequence transmitted in a time unit, the encoding method, the code rate, the sequence length, the sequence type, the sequence generation parameters, and the number of terminals or terminal groups associated with the sequence.

[0085] In some embodiments, for example, if the second sequence is a sequence generated by an OFDM waveform, the time unit may refer to an OFDM symbol; if the second sequence is a sequence generated by a CDM waveform, the time unit may refer to a CDM symbol; if the second sequence is a sequence generated by a TDM waveform, the time unit may refer to a TDM symbol; and if the second sequence is a sequence generated by a NOMA waveform, the time unit may refer to a NOMA symbol. For example, for a second sequence generated by an OFDM waveform, the number of bits of the first sequence transmitted in one time unit refers to the number of bits of the first sequence transmitted in one OFDM symbol.

[0086] For example, N1 = M × R × L, where M is the number of bits of the first sequence transmitted in one time unit; R is the code rate; and L is the number of OFDM symbols occupied by the first signal or the time domain duration of a first signal listening opportunity.

[0087] For example, N1 = R × L1, where L1 is the length of the encoded sequence after the first sequence or the length of the first sequence, and R is the code rate.

[0088] For example, N1 = L2, where L2 is the length of the sequence before encoding the first sequence or the length of the first sequence;

[0089] A12, N1 = K1 × K2, where K1 is the number of second sequences that transmit target information of different terminals or terminal groups, and K2 is the number of second sequences that transmit target information of the same terminal or terminal group, or K2 is the number of times the second sequence is repeatedly transmitted.

[0090] In some embodiments, under one implementation, K1 is determined based on at least one of the following:

[0091] The network device configuration, protocol agreement, the number of candidate second sequences associated with a resource location indicating ON in the symbol corresponding to the first waveform, the number of terminals or terminal groups associated with a first signal listening opportunity MO, the number of terminals or terminal groups indicated by the first signal, the information of the first sequence, and the information of the second sequence.

[0092] For example, if the first waveform is an OOK waveform, the symbol corresponding to the first waveform that indicates the enabled resource location can refer to the OOK ON symbol.

[0093] It should be noted that K1 can be a network device configuration, a protocol specification, or a number of candidate second sequences associated with a resource location indicated by the symbol corresponding to the first waveform, the number of terminals or terminal groups associated with a first signal listening opportunity MO, the number of terminals or terminal groups indicated by the first signal, information of the first sequence, and information of the second sequence.

[0094] In some embodiments, under one implementation, K2 is determined based on at least one of the following:

[0095] Network device configuration, K1, N1, protocol agreement, and first sequence information.

[0096] It should be noted that K2 can be a network device configuration, a protocol specification, or a value determined by the terminal based on at least one of the information in K1, N1, and the first sequence.

[0097] In some embodiments, the information of the second sequence referred to in this disclosure includes at least one of the following:

[0098] Encoding method, bit rate, sequence length, sequence generation parameters, number of terminals or number of terminal groups associated with the sequence.

[0099] A13, N1 = K3 + K4, where K3 is the number of second sequences that transmit target information of different terminals or terminal groups, and K4 is the number of times at least one of the K3 second sequences is repeatedly transmitted or the number of second sequences that are repeatedly transmitted among the K3 sequences.

[0100] In some embodiments, under one implementation, K3 is determined based on at least one of the following:

[0101] The network device configuration, protocol agreement, and symbols corresponding to the first waveform represent the number of candidate second sequences associated with a resource location, the number of terminals or terminal groups associated with an MO, the number of terminals or terminal groups indicated by the first signal, the information of the first sequence, and the information of the second sequence.

[0102] It should be noted that K3 can be a network device configuration, a protocol specification, or a number of candidate second sequences associated with a resource location, a number of terminals or terminal groups associated with an MO, a number of terminals or terminal groups indicated by a first signal, information of the first sequence, and information of the second sequence, as determined by the terminal based on at least one of the following: the number of candidate second sequences associated with a resource location, the number of terminals or terminal groups associated with an MO, information of the first signal, and information of the second sequence.

[0103] In some embodiments, under one implementation, K4 is determined based on at least one of the following:

[0104] Network device configuration, K3, N1, protocol agreement, and first sequence information.

[0105] It should be noted that K4 can be a network device configuration, a protocol specification, or a value determined by the terminal based on at least one of the information in K3, N1, and the first sequence.

[0106] For example, it can include the following two cases:

[0107] Case 1: When K3 is greater than or equal to K4, the K4 second sequences are subsets of the K3 second sequences;

[0108] Case 2: When K3 is less than K4, the second sequences of K3 are repeatedly transmitted floor(K4 / K3) times (K3-K4modK3), and the second sequences of K4modK3 are repeatedly transmitted ceil(K4 / K3) times.

[0109] Floor() is the floor function, and ceil() is the floor function.

[0110] A14, N1 = K5 × K6 + K7, where K5 is the number of second sequences that transmit target information from different terminals or terminal groups, K6 is the number of times the (K5-K7) second sequences are repeatedly transmitted, and K7 second sequences are repeatedly transmitted K6+1 times;

[0111] In some embodiments, under one implementation, K5 is determined based on at least one of the following:

[0112] The network device configuration, protocol agreement, and symbols corresponding to the first waveform represent the number of candidate second sequences associated with a resource location, the number of terminals or terminal groups associated with an MO, the number of terminals or terminal groups indicated by the first signal, the information of the first sequence, and the information of the second sequence.

[0113] In some embodiments, under one implementation, K6 and K7 are determined based on at least one of the following:

[0114] Network device configuration, K5, N1, protocol conventions, the symbol corresponding to the first waveform represents the number of candidate second sequences associated with a resource location, the number of terminals or terminal groups associated with an MO, the number of terminals or terminal groups indicated by the first signal, the generation sequence of the first sequence, and the generation sequence of the second sequence.

[0115] For example, it can include the following two cases:

[0116] Case 3: K6 = floor(N1 / K5), K7 = N1 - K6 × K5; K5 is the number of second sequences that transmit target information from different terminals or terminal groups, K6 is the number of times the second sequences (K5-K7) are repeatedly transmitted, and K7 second sequences are repeatedly transmitted K6+1 times;

[0117] Case 4: K6 = ceil(N1 / K5) - 1, K7 = N1 - K6 × K5; K5 is the number of second sequences that transmit target information from different terminals or terminal groups, K6 is the number of times the second sequences (K5-K7) are repeatedly transmitted, and K7 second sequences are repeatedly transmitted K6+1 times.

[0118] In some embodiments, in one implementation, the second sequence carries target information based on at least one sequence generation parameter.

[0119] In some embodiments, the sequence generation parameters mentioned in this disclosure include one of the following: root, cyclic shift, initial value for sequence generation, sequence generating polynomial, sequence length, and base sequence.

[0120] In some embodiments, under one implementation, the sequence generation parameters are related to at least one of the following:

[0121] The target information category, number of sequence generation parameters, cell identifier, MO index, MO group index, number of paging opportunities (PO) associated with the first signal monitoring opportunity, number of terminal groups under PO, number of terminals indicated by the first signal, number of terminal groups indicated by the first signal, number of MO groups in the same beam direction under the first signal monitoring opportunity, number of MO groups, number of candidate sequence generation parameter values, first information, number of first information associated with MO, number of first information associated with the first signal, and first parameter;

[0122] Wherein, the first parameter satisfies at least one of the following: pre-configured value, protocol agreement, determined based on cell identifier, determined based on target information category; the first information includes one of the following: terminal group index, terminal identifier, code point value carried by the first sequence, and segmented sequence information of at least one first sequence.

[0123] In some embodiments, the target information category includes at least one of the following:

[0124] The target information is terminal group-specific information, meaning that the target information is only applicable to one group of terminals;

[0125] The target information is terminal-specific, meaning that the target information is only applicable to one terminal.

[0126] The target information is common terminal information, meaning that the target information applies to all terminals associated with the first signal, the first sequence, or the second sequence;

[0127] The target information is common information for the terminal group, meaning that the target information applies to all terminal groups associated with the first signal, the first sequence, or the second sequence.

[0128] In some embodiments, the segmented sequence information includes at least one of the following:

[0129] The number of first sequence segments, the number of terminals or terminal groups indicated by a segment sequence, the number of bits in a sequence segment, and the bit value of a sequence segment.

[0130] The generation of the first signal will be explained below under the conditions of A11-A13 described above.

[0131] For A11, a first sequence and K2 or N1 identical second sequences (e.g., for A12, N1 = K2, K1 = 1) generate a joint sequence. The first sequence (ZC sequence, M sequence, GOLD sequence) carries the target information based on at least one sequence generation parameter.

[0132] In some embodiments, when the second sequence carries target information based on only one sequence generation parameter, the sequence generation parameter may be a root, a cyclic shift, an initial value for sequence generation, a sequence generating polynomial, a sequence length, or a base sequence. The sequence generation parameter may be a network device configuration or a protocol agreement, or it may be determined based on at least one of the following: target information category, number of sequence generation parameters, cell identifier, MO index, MO group index, number of paging opportunities (POs) associated with the first signal monitoring opportunity, number of terminal groups under POs, number of terminals indicated by the first signal, number of terminal groups indicated by the first signal, number of MO groups in the same beam direction under the first signal monitoring opportunity, number of MO groups, number of sequence generation parameter values, first information, number of first information associated with MOs, number of first information associated with the first signal, and first parameter.

[0133] For example, in some embodiments, in one implementation, the sequence generation parameters satisfy at least one of the following:

[0134] B11. If the target information is terminal group-specific information or terminal-specific information, the sequence generation parameters are determined based on the first information. If the target information is terminal common information, the sequence generation parameters are determined based on the number of first information associated with MO and / or the first signal.

[0135] For example, if the first information is a terminal group index, and if the target information is terminal group specific information or terminal specific information, the sequence generation parameter = f(terminal group index); if the target information is terminal common information or terminal group common information, the sequence generation parameter = the number of terminal group indices associated with MO or the first signal.

[0136] It should be noted that if the first information is the terminal identifier, then the sequence generation parameter = f(terminal identifier).

[0137] In some embodiments, if the first information is a terminal group index, and if it is terminal group-specific information or terminal-specific information, f(terminal group index) = terminal group index mod N2 or f(terminal group index) = terminal group index mod M1 (in this case, M1 = N2), where M1 is the number of MO groups transmitting different information in the same beam direction under a first signal monitoring opportunity or the number of MO groups under the same beam direction; if it is terminal (group) common information: sequence generation parameter = ceil(number of terminal group indices associated with MO / M1), or, sequence generation parameter = ceil(number of terminal group indices associated with MO / N2), or, sequence generation parameter = ceil(number of terminal group indices associated with MO / M1) + 1, or, sequence generation parameter = ceil(number of terminal group indices associated with MO / N2) + 1, where N2 is the number of possible values ​​for the sequence generation parameter.

[0138] In some embodiments, if the first information is a terminal identifier, and if the target information is terminal group-specific information or terminal-specific information, f(terminal identifier) ​​= terminal identifier mod N2 or f(terminal identifier) ​​= terminal identifier mod M1 (where M1 = N2), M1 is the number of MO groups transmitting different information in the same beam direction under a first signal monitoring opportunity or the number of MO groups in the same beam direction; if it is terminal common information or terminal group common information: sequence generation parameter = ceil(number of terminal group indices associated with MO / M1), or, sequence generation parameter = ceil(number of terminal identifiers associated with MO / N2), or, sequence generation parameter = ceil(number of terminal identifiers associated with MO / M1) + 1, or, sequence generation parameter = ceil(number of terminal identifiers associated with MO / N2) + 1, where N2 is the number of possible values ​​for the sequence generation parameter.

[0139] In some embodiments, in another case, if the first information is a terminal group index, if it is terminal group-specific information or terminal-specific information, f(terminal group index) = terminal group index mod(N2-1) or f(terminal group index) = terminal group index mod(M1-1) (in this case, M1 = N2), where M1 is the number of MO groups transmitting different information in the same beam direction under a first signal listening opportunity or the number of MO groups under the same beam direction; if it is terminal common information: sequence generation parameter = ceil(number of terminal group indices associated with MO / M1), or sequence generation parameter = ceil(number of terminal group indices associated with MO / N2), or sequence generation parameter = ceil(number of terminal group indices associated with MO / M1)+1, or sequence generation parameter = ceil(number of terminal group indices associated with MO / N2)+1.

[0140] In some embodiments, in another case, if the first information is a terminal identifier, if it is terminal group-specific information or terminal-specific information, f(terminal identifier) ​​= terminal group index mod(N2-1) or f(terminal identifier) ​​= terminal identifier mod(M1-1) (in this case, M1 = N2), where M1 is the number of MO groups transmitting different information in the same beam direction under a first signal listening opportunity or the number of MO groups under the same beam direction; if it is terminal common information: sequence generation parameter = ceil(number of terminal identifiers associated with MO / M1), or sequence generation parameter = ceil(number of terminal identifiers associated with MO / N2), or sequence generation parameter = ceil(number of terminal identifiers associated with MO / M1)+1, or sequence generation parameter = ceil(number of terminal identifiers associated with MO / N2)+1.

[0141] B12. If the target information is terminal group-specific information, the sequence generation parameters are determined based on the first information and / or the cell identifier. If the target information is terminal common information, the sequence generation parameters are determined based on the number of first information associated with the MO and / or the first signal and / or the cell identifier.

[0142] For example, if the first information is a terminal group index, and the target information is terminal group-specific information or terminal-specific information, the sequence generation parameter = f(terminal group index) + cell identifier; if the target information is terminal public information, the sequence generation parameter = number of terminal group indices associated with MO + cell identifier.

[0143] For example, if the first information is the terminal group index, and if the target information is terminal group-specific information or terminal-specific information, the sequence generation parameter = f(terminal identifier) ​​+ cell identifier; if the target information is terminal public information, the sequence generation parameter = number of terminal identifiers associated with MO + cell identifier.

[0144] In some embodiments, the specific implementations of f(terminal group index) and f(terminal identifier) ​​can be found in the description in B11 above.

[0145] B13. The sequence generation parameters are determined based on the terminal group index, terminal identifier, the number of sequence generation parameter values, the number of MO groups in the same beam direction under the first signal monitoring opportunity, and / or T. The value of T is related to the target information category.

[0146] For example, if the first information is the terminal group index, the sequence generation parameter = (f(terminal group index) + 1) × T) mod N2, or the sequence generation parameter = (f(terminal group index) + 1) × T) mod M1; when the target information is terminal group specific information or terminal specific information, T = 1, and when the target information is terminal common information or terminal group common information, T = 0.

[0147] For example, if the first information is the terminal group index, the sequence generation parameter = ((f(terminal group index)+1)×T)mod M1, or the sequence generation parameter = ((f(terminal group index)+1)×T)mod M2; when the target information is terminal group-specific information or terminal-specific information, T = cell identifier; when the target information is terminal public information, T = cell identifier+1.

[0148] For example, if the first information is a terminal identifier, the sequence generation parameter = (f(terminal identifier) ​​+ 1) × T) mod N2, or the sequence generation parameter = (f(terminal identifier) ​​+ 1) × T) mod M1; when the target information is terminal group-specific information or terminal-specific information, T = 1, and when the target information is terminal public information or terminal group public information, T = 0.

[0149] For example, if the first information is the terminal identifier, the sequence generation parameter = ((f(terminal identifier)+1)×T)mod M1, or the sequence generation parameter = ((f(terminal identifier)+1)×T)mod M2; when the target information is terminal group-specific information or terminal-specific information, T = cell identifier; when the target information is terminal public information or terminal group public information, T = cell identifier+1.

[0150] B14. The sequence generation parameters are determined based on the cell identifier, the number of MO groups in the same beam direction under the first signal monitoring opportunity, and the number of sequence generation parameter values.

[0151] For example, sequence generation parameter = g(cell identifier) ​​mod(M1×N2);

[0152] In some embodiments, g(cell identifier) ​​= cell identifier mod N4, N4 = 4 or other predefined / configured values;

[0153] In some embodiments, g(cell identifier) ​​= cell identifier mod N4 + N5; N4 and N5 can be predefined or preconfigured.

[0154] In some embodiments, when the second sequence carries target information based on at least two sequence generation parameters, the at least two sequence generation parameters can be at least two of the following: root, cyclic shift, initial value of sequence generation, sequence generating polynomial, sequence length, or base sequence; the sequence generation parameters can be network device configuration or protocol agreement, or, in some embodiments, in one implementation, at least two sequence generation parameters satisfy at least one of the following:

[0155] C11. One or more of the at least two sequence generation parameters are determined based on the cell identifier, and the values ​​of the remaining sequence generation parameters among the at least two sequence generation parameters carry target information.

[0156] C12. At least two sequence generation parameters jointly carry the target information;

[0157] In some embodiments, under one implementation, the at least two sequence generation parameters jointly carry target information, including:

[0158] The value of one or more of at least two sequence generation parameters carries the MO index, and the remaining sequence generation parameters of at least two sequence generation parameters carry the index within the PO associated with the MO of the wake-up terminal group.

[0159] For example, taking the second sequence as an example of generating target information based on two sequence parameters, the two sequence parameters are: root and cyclic shift; in one case, the root carries the MO index, and the cyclic shift carries the index of the terminal group under the PO associated with the MO where the wake-up terminal group is located; in another case, the cyclic shift carries the MO index, and the root carries the index of the terminal group under the PO associated with the MO where the wake-up terminal group is located.

[0160] C13. At least two sequence generation parameters jointly carry cell information.

[0161] For A12, a first sequence and N1 = K1 × K2 (K1 > 1) second sequences are used to generate a joint sequence, where the second sequences carry target information based on at least one sequence generation parameter.

[0162] In this case, the K1 second sequences that transmit different information belong to the same sequence set or are generated based on a set of second sequence configuration parameters, and the information they carry includes at least one of the following:

[0163] The wake-up information of a portion of the terminal or terminal group associated with the first signal;

[0164] The first sequence transmits information in at least one segment;

[0165] The first sequence carries information about a portion of the codepoints;

[0166] Community-level index information.

[0167] In one scenario, N1 second sequences belong to the same set of second sequences. The sequence generation parameters carry target information and are related to at least one of the following: target information category, number of sequence generation parameters, cell identifier, MO index, MO group index, number of paging opportunities (POs) associated with the first signal monitoring opportunity, number of terminal groups under POs, number of terminals indicated by the first signal, number of terminal groups indicated by the first signal, number of MO groups in the same beam direction under the first signal monitoring opportunity, number of MO groups, number of sequence generation parameter values, first information, number of first information associated with MOs, number of first information associated with the first signal, and first parameter. The determination method can be as follows:

[0168] The functional relationship between the sequence generation parameters and the above information is: sequence generation parameters = f(X) mod K1 or sequence generation parameters = g(X) mod K1;

[0169] X can be at least one of the following: terminal group index, code point value carried by the first sequence, or segment sequence information of at least one first sequence.

[0170] The relationship between the functions f(X) and g(X) can be found in the description above, and will not be repeated here.

[0171] In another scenario, the N1 sequences belong to different OFDM sequence sets. The sequence generation parameters carry target information and are related to at least one of the following: target information category, number of sequence generation parameters, cell identifier, MO index, MO group index, number of paging opportunities (POs) associated with the first signal monitoring opportunity, number of terminal groups under POs, number of terminals indicated by the first signal, number of terminal groups indicated by the first signal, number of MO groups in the same beam direction under the first signal monitoring opportunity, number of MO groups, number of sequence generation parameter values, first information, number of first information associated with MOs, number of first information associated with the first signal, and first parameter. The determination method can be as follows:

[0172] The values ​​of the sequence generation parameters for the N1 second sequences are determined based on the configuration parameter set of the K2 OFDM sequence sets, which includes the sequence generation parameters.

[0173] For A13, a first sequence and N1 = K3 + K4 (K3 > 1) or N1 = K5 × K6 + K7 second sequences are used to generate a joint sequence, where the second sequences carry target information based on at least one sequence generation parameter.

[0174] In this case, the K3 and K5 second sequences that transmit different information belong to the same sequence set or are generated based on a set of second sequence configuration parameters, and the information they carry includes at least one of the following:

[0175] The wake-up information of a portion of the terminal or terminal group associated with the first signal;

[0176] The first sequence transmits information from at least one segment;

[0177] The first sequence carries information about a portion of the codepoints;

[0178] Community-level index information.

[0179] In one scenario, N1 sequences belong to the same OFDM sequence set. The sequence generation parameters carry target information and are related to at least one of the following: target information category, number of sequence generation parameters, cell identifier, MO index, MO group index, number of paging opportunities (POs) associated with the first signal monitoring opportunity, number of terminal groups under POs, number of terminals indicated by the first signal, number of terminal groups indicated by the first signal, number of MO groups in the same beam direction under the first signal monitoring opportunity, number of MO groups, number of sequence generation parameter values, first information, number of first information associated with MOs, number of first information associated with the first signal, and first parameter. The determination method is as follows:

[0180] The functional relationship between the sequence generation parameters and the above information is: sequence generation parameters = f(X) mod K1 or sequence generation parameters = g(X) mod K1;

[0181] X can be at least one of the following: terminal group index, code point value carried by the first sequence, or segment sequence information of at least one first sequence.

[0182] The relationship between the functions f(X) and g(X) can be found in the description above, and will not be repeated here.

[0183] In another scenario, the N1 second sequences belong to different sets of second sequences. The sequence generation parameters carry target information and are related to at least one of the following: target information category, number of sequence generation parameters, cell identifier, MO index, MO group index, number of paging opportunities (POs) associated with the first signal monitoring opportunity, number of terminal groups under POs, number of terminals indicated by the first signal, number of terminal groups indicated by the first signal, number of MO groups in the same beam direction under the first signal monitoring opportunity, number of MO groups, number of sequence generation parameter values, first information, number of first information associated with MOs, number of first information associated with the first signal, and first parameter. The determination method is as follows:

[0184] The values ​​of the sequence generation parameters for the N1 second sequences are determined based on the configuration parameter set of the K2 OFDM sequence sets, which includes the sequence generation parameters.

[0185] The following example illustrates the specific application of this embodiment, using the first sequence as the sequence generated by the OOK waveform and the second sequence as the sequence generated by the OFDM waveform, and the base station transmitting wake-up information to the terminal.

[0186] Application Scenario 1: LP-WUS carries OFDM sequences, and the OFDM sequence generation method adopts the A11 method described above.

[0187] Specifically, the main implementation process includes:

[0188] Step S11: The terminal determines the waveform information of the first signal based on the protocol agreement and / or the first configuration information, including the first sequence of OOK waveform generation and / or the second sequence of OFDM waveform generation jointly generating the first signal.

[0189] Specifically, the first signal is LP-WUS.

[0190] In some embodiments, the first configuration information includes at least one of the following: OOK waveform information, OFDM waveform information, information on a first sequence of OOK waveform generation, information on a second sequence of OFDM waveform generation, LP-WUS resource location, and LP-WUS bandwidth.

[0191] In some embodiments, the OOK waveform information includes at least one of the following: OOK waveform type (including OOK-1, OOK-4 or other waveform types), M (M represents the number of OOK chips / bits of an OFDM symbol transmission), and Discrete Fourier Transform (DFT) / Ordinary Least Squares (LS) size (which can be represented by X).

[0192] The information of the first sequence and / or the second sequence includes: M, at least one encoding method (e.g., Manchester coding, RM coding), at least one code rate, sequence type (GOLD sequence, Walsh sequence, ZC sequence, M sequence), sequence length, sequence generation parameters (including but not limited to at least one of the following: cyclic shift (CS), initial value for sequence generation, sequence length, sequence generator polynomial, root, base sequence), and at least one of the following: number of terminals or number of terminal groups associated with the sequence.

[0193] Example 1: The sequence type is ZC sequence, and the sequence generation expression is: s′(n)=Xq ((n+C V )mod B ZC ), n = 0, ..., L ZC -1;

[0194] Among them, C v For cyclic shift, L zc B is the length of the OFDM sequence. zc For less than L zc The largest odd or prime number, where q is the root.

[0195] The LP-WUS sequence is a sequence generated based on a first sequence generated from OOK waveforms and / or a second sequence generated from N1 OFDM waveforms, including one of the following two methods:

[0196] N1 OFDM sequences carry the wake-up information of the same terminal or terminal group, which can also be described as an OFDM sequence being transmitted N1 times on an LP-WUS;

[0197] The terminal determines N1 based on configuration information and / or predefined rules, including one of the following:

[0198] Method 1: Based on base station configuration, that is, the base station directly configures N1, where N1 represents the number of LP-WUS scrambled OFDM sequences or the number of times the OFDM sequence is repeatedly transmitted;

[0199] Method 2: The first sequence generation parameters are determined based on the base station configuration. The first sequence generation parameters include: the waveform parameters of the first sequence, the coding rate of the first sequence, and the sequence length L of the first sequence.

[0200] For example, N1 = M × R × L;

[0201] For example, N1 = M × L;

[0202] For example, N1 = L1 × R;

[0203] For example, N1 = L2;

[0204] Where R is the coding rate, L is the length of time-domain resources occupied by the first signal or the first sequence (e.g., the number of OFDM symbols), M is the waveform parameter of the first sequence, i.e., the number of bits of the first sequence transmitted by one OFDM symbol; L1 is the bit length of the first sequence after encoding or the length of the first sequence; L2 is the bit length of the first sequence before encoding or the length of the first sequence.

[0205] Step S12: The terminal receives at least one OFDM sequence and / or OOK sequence in LP-WUS and obtains wake-up information and / or cell index information (e.g., partial cell index information);

[0206] In some embodiments, the wake-up information includes at least one of the following types:

[0207] Terminal-level wake-up message, waking up a specific terminal;

[0208] Terminal group level wake-up information wakes up a specific terminal group, which can be a terminal group next to a PO or a terminal group determined by other means;

[0209] Public wake-up message, wakes up all terminals or terminal groups that receive this LP-WUS or wakes up all terminals or terminal groups associated with LP-WUS / MO.

[0210] In some embodiments, the terminal obtains wake-up information type and / or wake-up information based on at least one OFDM sequence, the information being carried in the sequence generation parameters of at least one OFDM sequence, including one of the following methods:

[0211] Method 11: The OFDM sequence is based on a sequence generation parameter that carries wake-up information and / or part of the cell index information.

[0212] The OFDM sequence generation parameters include: root, cyclic shift, initial value for sequence generation, sequence generating polynomial, sequence length, and one term in the base sequence;

[0213] The values ​​of the sequence generation parameters are related to at least one of the following: wake-up information category, terminal group index, terminal identifier, number of sequence generation parameter values ​​N2, cell identifier (Cell-ID), MO index, MO group index, number of POs associated with the LP-WUS listening opportunity, number of terminal groups under the PO, and number of MO groups in the same beam direction under the LP-WUS listening opportunity (which can be represented by G). The rules for determining the sequence generation parameters include at least one of the following:

[0214] Rule 1: In one scenario, if the wake-up information is terminal group-specific information, the sequence generation parameter = f(terminal group index); if the wake-up information is terminal common information or terminal group common information, the sequence generation parameter = number of terminal groups associated with MO or LP-WUS + H, where H can be 0 or other integers, and can be base station configuration or protocol agreement. In another scenario, if the wake-up information is terminal-specific information, the sequence generation parameter = f(terminal identifier); if the wake-up information is terminal common information or terminal group common information, the sequence generation parameter = number of terminals associated with MO or LP-WUS + H, where H can be 0 or other integers, and can be base station configuration or protocol agreement.

[0215] The functions f(terminal group index) and f(terminal identifier) ​​can include at least one of the following: round down, round up, modulo, multiplication, addition, and division;

[0216] Example 1: If it is terminal group-specific information or terminal-specific information, f(terminal group index) = terminal group index mod N2 or f(terminal group index) = terminal group index mod G (in this case, G = N2), where G is the number of MO groups in the same beam direction under one LP-WUS listening opportunity; if it is terminal common information or terminal group common information, the sequence generation parameter = ceil(number of terminal groups associated with MO / M1), or the sequence generation parameter = ceil(number of terminal groups associated with MO / N2), or the sequence generation parameter = ceil(number of terminal groups associated with MO / M1) + 1, or the sequence generation parameter = ceil(number of terminal groups associated with MO / N2) + 1.

[0217] Example 2: If it is terminal group-specific information or terminal-specific information, f(terminal identifier) ​​= terminal identifier mod N2 or f(terminal identifier) ​​= terminal identifier mod G (in this case, G = N2), where G is the number of MO groups in the same beam direction under one LP-WUS listening opportunity; if it is terminal common information or terminal group common information, the sequence generation parameter = ceil(number of terminal groups associated with MO / M1), or the sequence generation parameter = ceil(number of terminal groups associated with MO / N2), or the sequence generation parameter = ceil(number of terminal groups associated with MO / M1) + 1, or the sequence generation parameter = ceil(number of terminal groups associated with MO / N2) + 1.

[0218] Rule 2. In one scenario, if the information is terminal group-specific or terminal-specific, the sequence generation parameter = f(terminal group index) + cell identifier; if the information is terminal common information, the sequence generation parameter = number of terminal group indices associated with MO or LP-WUS + cell identifier. In another scenario, if the information is terminal-specific or terminal-specific, the sequence generation parameter = f(terminal identifier) ​​+ cell identifier; if the information is terminal common information or terminal group common information, the sequence generation parameter = number of terminals associated with MO or LP-WUS + cell identifier.

[0219] In some embodiments, the f(terminal group index) and f(terminal identifier) ​​functions may include at least one of the following: round down, round up, modulo, multiplication, addition, and division.

[0220] Rule 3. In one case, the sequence generation parameter = ((f(terminal group index) + 1) × T) mod N2 or the sequence generation parameter = ((f(terminal group index) + 1) × T) mod G. If it is terminal-specific information or terminal group-specific information, T = n1; if it is terminal common information, T = n2. In another case, the sequence generation parameter = ((f(terminal identifier) ​​+ 1) × T) mod N2 or the sequence generation parameter = ((f(terminal identifier) ​​+ 1) × T) mod G. If it is terminal-specific information or terminal group-specific information, T = n1; if it is terminal common information, T = n2.

[0221] In some embodiments, n1 and n2 can be determined by base station configuration or protocol agreement, for example, the protocol agreement may specify n1 = 1 and n2 = 0.

[0222] Rule 4. In one scenario, the sequence generation parameter = ((f(terminal group index) + 1) × T) mod N2 or the sequence generation parameter = ((f(terminal group index) + 1) × T) mod G. If it is terminal group-specific information or terminal-specific information, T = cell identifier; if it is terminal common information, T = cell identifier + 1. In another scenario, the sequence generation parameter = ((f(terminal identifier) ​​+ 1) × T) mod N2 or the sequence generation parameter = ((f(terminal identifier) ​​+ 1) × T) mod G. If it is terminal (group)-specific information or terminal-specific information, T = cell identifier; if it is terminal common information, T = cell identifier + 1.

[0223] Rule 5: Sequence generation parameter = g(cell identifier) ​​mod(G×N2);

[0224] In some embodiments, g(cell identifier) ​​= cell identifier mod N4, N4 = 4 or other predefined / configured values;

[0225] In some embodiments, g(cell identifier) ​​= cell identifier mod N4 + N5; N4 and N5 can be predefined or preconfigured;

[0226] In some embodiments, the g(cell identifier) ​​function may include at least one of the following: rounding down, rounding up, modulo, multiplication, addition, and division.

[0227] Method 12: Wake up information and / or part of cell index information based on the values ​​of one sequence generation parameter (hereinafter referred to as the first parameter) and another sequence generation parameter (hereinafter referred to as the second parameter).

[0228] The first parameter and / or the second parameter include: root, cyclic shift, initial value for sequence generation, sequence generating polynomial, sequence length, and one term in the base sequence;

[0229] The rules for determining the first and second parameters include at least one of the following:

[0230] Method 1: The first parameter is determined based on the cell ID, and the value of the second parameter carries the wake-up information;

[0231] The first parameter = g(cell identifier) ​​= cell identifier mod N4 + N5, where N4 = 4 or other predefined / configured values, and N5 = 0 or other predefined / configured values;

[0232] The method for determining the second parameter is the same as rule one and rule three in method one;

[0233] Method 2: The second parameter is determined based on the Cell ID, and the value of the first parameter carries the wake-up information;

[0234] Method 3: The first and second parameters together carry the wake-up information;

[0235] In some embodiments, the first parameter carries the MO Index, and the second parameter carries the index within the terminal group under the PO associated with the MO where the wake-up terminal group is located;

[0236] In some embodiments, the second parameter carries the MO Index, and the first parameter carries the index within the terminal group under the PO associated with the MO where the wake-up terminal group is located.

[0237] Method 4: The first and second parameters together carry Cell information.

[0238] Step S13: The terminal receives at least one OFDM sequence from LP-WUS. The sequence generation parameters carry one or more of the following: serving cell partial cell index information, terminal group index, and terminal identifier. Then, the terminal is woken up.

[0239] Application Scenario 2: LP-WUS carries OFDM sequences, and the OFDM sequence generation method adopts the A12 method described above.

[0240] Specifically, the main implementation process includes:

[0241] Step S21: The terminal determines the waveform information of the first signal based on the protocol agreement and / or the first configuration information, including the first sequence of OOK waveform generation and / or the second sequence of OFDM waveform generation jointly generating the first signal.

[0242] Specifically, the first signal is LP-WUS.

[0243] In some embodiments, the first configuration information includes at least one of the following: OOK waveform information, OFDM waveform information, information on a first sequence of OOK waveform generation, information on a second sequence of OFDM waveform generation, LP-WUS resource location, and LP-WUS bandwidth.

[0245] In some embodiments, the information of the first sequence and / or the second sequence includes: M, at least one encoding method (e.g., Manchester coding, RM coding), at least one code rate, sequence type (GOLD sequence, Walsh sequence, ZC sequence, M sequence), sequence length, sequence generation parameters (including but not limited to at least one of the following: cyclic shift (CS), initial value for sequence generation, sequence length, sequence generation polynomial, root, base sequence), and at least one of the number of terminals or terminal groups associated with the sequence;

[0246] Example 1: The sequence type is ZC sequence, and the sequence generation expression is: s′(n)=X q ((n+C V )mod B ZC ), n = 0, ..., L ZC -1;

[0247] In some embodiments, the LP-WUS sequence is a sequence generated based on a first sequence generated from OOK waveforms and / or a second sequence generated from N1 OFDM waveforms, including at least one of the following:

[0248] Method 1: The terminal determines N1 based on configuration information and / or predefined rules, including one of the following:

[0249] D11. Based on base station configuration, that is, the base station directly configures N1, where N1 represents the number of LP-WUS scrambling OFDM sequences;

[0250] D12. The first sequence generation parameters based on the base station configuration are determined. The first sequence generation parameters include: first sequence waveform parameters, first sequence coding rate, and first sequence length.

The configuration information is based on at least one configuration in Radio Resource Control (RRC) signaling, System Information Block (SIB, e.g., SIB-X (X = 1, 2, ...)), or Master Information Block (MIB).

[0272] In some embodiments, K1 is the number of OFDM sequences transmitting different terminal wake-up information, and K2 is the number of OFDM sequences of terminals transmitting the same wake-up information or the number of times an OFDM sequence is repeatedly transmitted.

The rules for determining the sequence generation parameters include at least one of the following:

[0278] Rule 1: In one scenario, if the wake-up information is terminal group-specific information or terminal-specific information, the sequence generation parameter = f(terminal group index); if the wake-up information is terminal common information or terminal group common information, the sequence generation parameter = number of terminal groups associated with MO or LP-WUS + H, where H can be 0 or other integers, and can be base station configuration or protocol agreement. In another scenario, if the wake-up information is terminal group-specific information or terminal-specific information, the sequence generation parameter = f(terminal identifier); if the wake-up information is terminal common information or terminal group common information, the sequence generation parameter = number of terminal groups associated with MO or LP-WUS + H, where H can be 0 or other integers, and can be base station configuration or protocol agreement.

[0279] The functions f(terminal group index) and f(terminal identifier) ​​can include at least one of the following: round down, round up, modulo, multiplication, addition, and division;

[0280] Example 1: For example, if it is terminal group-specific information or terminal-specific information, f(terminal group index) = terminal group index mod N2 or f(terminal group index) = terminal group index mod G (in this case, G = N2), where G is the number of MO groups in the same beam direction under one LP-WUS listening opportunity; if it is terminal common information or terminal group common information, sequence generation parameter = ceil(number of terminal groups associated with MO / M1) mod K1, sequence generation parameter = ceil(number of terminal groups associated with MO / N2) mod K1 or sequence generation parameter = (ceil(number of terminal group indices associated with MO / M1) + 1) mod K1, or sequence generation parameter = (ceil(number of terminal group indices associated with MO / N2) + 1) mod K1.

[0281] For example, if it is terminal group-specific information or terminal-specific information, f(terminal identifier) ​​= terminal identifier mod N2 or f(terminal identifier) ​​= terminal identifier mod G (in this case, G = N2), where G is the number of MO groups in the same beam direction under one LP-WUS listening opportunity; if it is terminal common information or terminal group common information, sequence generation parameter = ceil(number of terminal groups associated with MO / M1) mod K1, sequence generation parameter = ceil(number of terminal groups associated with MO / N2) mod K1 or sequence generation parameter = (ceil(number of terminal group indices associated with MO / M1) + 1) mod K1, or sequence generation parameter = (ceil(number of terminal group indices associated with MO / N2) + 1) mod K1.

[0283] For example, if it is terminal group-specific information or terminal-specific information, f(terminal identifier) ​​= terminal identifier mod(N2-1), or f(terminal identifier) ​​= terminal group index mod(M1-1) (in this case, M1 = N2), where M1 is the number of MOs transmitting different information in the same beam direction under one LP-WUS listening opportunity or the number of MOs under the same beam; if it is terminal common information or terminal group common information, the sequence generation parameter = ceil(number of terminal groups associated with MO / M1), or the sequence generation parameter = ceil(number of terminal groups associated with MO / N2), or the sequence generation parameter = ceil(number of terminal groups associated with MO / M1)+1, or the sequence generation parameter = ceil(number of terminal groups associated with MO / N2)+1; if it does not carry wake-up information, the value of the sequence generation parameter is N2 or N1.

[0284] Rule 2: In one scenario, if the information is terminal group-specific or terminal-specific, the sequence generation parameter = f(terminal group index) + cell identifier; if the information is terminal common information or terminal group common information, the sequence generation parameter = number of terminal group indices associated with MO or LP-WUS + cell identifier. In another scenario, if the information is terminal group-specific or terminal-specific, the sequence generation parameter = f(terminal identifier) ​​+ cell identifier; if the information is terminal common information or terminal group common information, the sequence generation parameter = number of terminal group indices associated with MO or LP-WUS + cell identifier.

[0285] In some embodiments, the f(terminal group index) and f(terminal identifier) ​​functions may include at least one of the following: rounding down, rounding up, modulo, multiplication, addition, and division.

[0286] Rule 3: In one case, the sequence generation parameter = ((f(terminal group index) + 1) × T) mod N2 or the sequence generation parameter = ((f(terminal group index) + 1) × T) mod G. If it is terminal group-specific information or terminal-specific information, T = n1; if it is terminal common information or terminal group common information, T = n2. In another case, the sequence generation parameter = ((f(terminal identifier) ​​+ 1) × T) mod N2 or the sequence generation parameter = ((f(terminal identifier) ​​+ 1) × T) mod G. If it is terminal group-specific information or terminal-specific information, T = n1; if it is terminal common information or terminal group common information, T = n2.

[0287] In some embodiments, n1 and n2 can be determined by base station configuration or protocol agreement, for example, the protocol agreement may specify n1 = 1 and n2 = 0.

[0288] Rule 4: In one scenario, the sequence generation parameter = ((f(terminal group index) + 1) × T) mod N2 or the sequence generation parameter = ((f(terminal group index) + 1) × T) mod G. If it is terminal group-specific information or terminal-specific information, T = cell identifier; if it is terminal common information or terminal group common information, T = cell identifier + 1. In another scenario, the sequence generation parameter = ((f(terminal identifier) ​​+ 1) × T) mod N2 or the sequence generation parameter = ((f(terminal identifier) ​​+ 1) × T) mod G. If it is terminal group-specific information or terminal-specific information, T = cell identifier; if it is terminal common information or terminal group common information, T = cell identifier + 1.

[0310] The functional relationship of the OFDM parameter determination rule is the same as that of rules one through five in Method 1. The difference is that the subgroup index in the formula is replaced by the codepoint value carried by the OOK sequence or the OOK sequence information of at least one OOK segment (sequence generation parameter, at least one of the decimal values ​​corresponding to the binary sequence).

[0488] Example 1: The sequence type is ZC sequence, and the sequence generation expression is: s′(n)=X q ((n+C V )mod B ZC ), n = 0, ..., L ZC -1;

[0489] Among them, C v For cyclic shift, Lzc B is the length of the OFDM sequence. zc For less than L zc The largest odd or prime number, where q is the root.

[0490] The LP-SS sequence is a sequence generated based on a first sequence generated from OOK waveforms and / or a second sequence generated from N1 OFDM waveforms, including:

[0491] N1 OFDM sequences carry the same cell partial index information or do not carry information (fixed sequence), which can also be said to be an OFDM sequence repeatedly transmitted N1 times on an LP-WUS signal;

[0492] The terminal determines N1 based on configuration information and / or predefined rules, including one of the following:

[0493] D51. Based on base station configuration, that is, the base station directly configures N1, where N1 represents the number of LP-SS scrambled OFDM sequences or the number of times the OFDM sequence is repeatedly transmitted;

[0494] D52. The first sequence generation related parameters based on the base station configuration are determined. The first sequence generation includes: the waveform parameters of the first sequence, the coding rate of the first sequence, and the sequence length of the first sequence.

[0495] For example, N1 = M × R × L;

[0496] For example, N1 = M × L;

[0497] For example, N1 = L1 × R;

[0498] For example, N1 = L2;

[0499] Where R is the coding rate, L is the length of time-domain resources occupied by the first signal or the first sequence (e.g., the number of OFDM symbols), M is the waveform parameter of the first sequence, i.e., the number of bits of the first sequence transmitted by one OFDM symbol; L1 is the bit length of the first sequence after encoding or the length of the first sequence; L2 is the bit length of the first sequence before encoding or the length of the first sequence.

[0500] Step S52: The terminal receives at least one OFDM sequence and / or OOK waveform sequence from the LP-SS to obtain partial cell index information and / or synchronization information;

[0501] In some embodiments, the terminal obtains partial cell index information and / or synchronization information based on at least one OFDM sequence, wherein the information is carried in the generation parameters of at least one OFDM sequence, including one of the following methods:

[0502] Method 1: OFDM sequence is based on a sequence generation parameter that carries part of the cell index information.

[0503] The OFDM sequence generation parameters include: root, cyclic shift, initial value for sequence generation, sequence generating polynomial, sequence length, and one term in the base sequence;

[0504] The values ​​of the sequence generation parameters are related to at least one of the following: terminal identifier, number of sequence generation parameter values, cell identifier, number of OFDM sequences, and number of OOK sequences. The rules for determining the sequence generation parameters include at least one of the following:

[0505] Rule 1: Sequence generation parameter = f(cell identifier) ​​+ H, where H can be 0 or other integers, and can be base station configuration or protocol agreement;

[0506] The f(cell identifier) ​​function can include at least one of the following: round down, round up, modulo, multiplication, addition, and division;

[0507] Example 1: f(cell ID) = cell ID mod K R or K Q ;

[0508] Among them, K R K is the number of OFDM sequences. Q The number of OOK sequences.

[0509] Method 2: Based on the values ​​of one sequence generation parameter (hereinafter referred to as the first parameter) and another sequence generation parameter (hereinafter referred to as the second parameter), wake-up information and / or part of the cell index information are jointly obtained.

[0510] In some embodiments, the first parameter and / or the second parameter includes: root, cyclic shift, initial value for sequence generation, sequence generating polynomial, sequence length, and one term in the base sequence;

[0511] In some embodiments, the rules for determining the first parameter and the second parameter include at least one of the following:

[0512] Method 1: The first parameter is determined based on the cell identifier, and the value of the second parameter carries the wake-up terminal information;

[0513] The first parameter = g(cell identifier) ​​= cell identifier mod N4 + H1, where N4 = 4 or other predefined / configured values, and H1 = 0 or other predefined / configured values;

[0514] The second parameter = g(cell identifier) ​​= cell identifier mod N5 + H2, where N5 = 4 or other predefined / configured values, and H2 = 0 or other predefined / configured values.

[0515] Step S53: The terminal receives at least one OFDM sequence and / or OOK waveform sequence from the LP-SS to obtain partial index information and / or synchronization information of the serving cell.

[0516] It should be noted that there are no signals generated based on OOK waveforms and OFDM waveforms in the related technologies, and an OFDM signal carries all the target information (wake-up information, synchronization information, cell index information, etc.); in addition, for LP-WUS, the larger M is, the shorter the length of the OFDM sequence scrambled on a single OOK symbol, and the number of sequences that can be generated is insufficient to carry all LP-WUS indication information; the OFDM sequence generation method and the method of carrying the bit at the position of OOK symbol to indicate that the bit is 1 in the embodiments of this disclosure can solve the above-mentioned problems, thereby ensuring communication reliability.
