Description

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

[0001] This disclosure claims priority to Chinese Patent Application No. 202411590642.1, filed with the Chinese Patent Office on November 8, 2024, 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 concepts of Low Power Wake-up Signal (LP-WUS) and Low Power Wake-Up Receiver (LP-WUR) to further reduce terminal energy consumption based on relevant energy-saving technologies. When there is no service transmission at the base station and terminal, the power-consuming main radio (MR) is turned off, while the LP-WUR device is turned on to receive the low-power signal sent by the base station. When there is service transmission, the base station activates the main radio through LP-WUS to complete the service transmission. This can significantly save the terminal's power consumption when there is no service transmission.

[0049] The following is a brief explanation of the relevant concepts mentioned in this disclosure.

[0050] I. LP-WUS Signal Generation

[0051] The LP-WUS research project focuses on a method for generating LP-WUS based on the superposition of Orthogonal Frequency Division Multiplexing (OFDM) waveforms and On-Off Keying (OOK) waveforms. The OOK waveform requires the standardization of both the OOK-1 and OOK-waveforms. The OOK waveform carries the 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 this conference.

[0052] OOK-1 waveform: One OFDM symbol corresponds to a single-bit. The method of mapping LP-WUS to a subcarrier (SC) is as follows:

[0053] OOK=1 means that all SCs are used for modulation;

[0054] OOK=0 means that all SCs have zero power (from the baseband perspective).

[0055] 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.

[0056] II. Wake-up Signal Generation Method

[0057] In Radio Resource Control (RRC) Idle / Inactive (RRC_IDLE / INACTIVE) mode, DCI 2_7 is a downlink control signal generated based on OFDM signals. The wake-up indication field in the signal, based on a bitmap, simultaneously indicates whether multiple terminal groups are awake and receiving paging messages at the paging opportunity (PO) location. In RRC_CONNECTED mode, DCI 2_6 is a downlink control signal generated based on OFDM signals. The wake-up indication field in the signal, based on a bitmap, simultaneously indicates whether multiple terminals are in DRX active state to receive downlink data.

[0058] When designing LP-WUS jointly generated by OOK and OFDM, the following problems need to be solved:

[0059] 1) The LP-WUS signal simultaneously instructs N groups (N>=1) of receivers to wake up. Each group of receivers may contain both OFDM and OOK receivers. It is necessary to design a method for generating the joint LP-WUS signal that can simultaneously carry the wake-up information of both OFDM and OOK receivers.

[0060] 2) OFDM sequences are superimposed on a single OOK ON symbol for transmission. The number of OFDM sequences is insufficient to carry all the information carried by LP-WUS. A single OFDM sequence can only carry part of the wake-up information carried by LP-WUS. The design of the information carried by OFDM sequences and how OFDM-based LP-WUS can obtain all the information carried by LP-WUS need to be studied.

[0061] The embodiments disclosed herein can also solve the above-mentioned problems.

[0062] 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.

[0063] 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 a user equipment (UE), such as a mobile phone, tablet 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 base station using 5G or later versions of mobile communication technology (e.g., gNB, 5G NR NB), 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.

[0064] This disclosure provides an information acquisition and transmission method, apparatus, terminal, and network device to accurately acquire wake-up indication information and / or transmission indication information.

[0065] 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.

[0066] As shown in Figure 1, this embodiment of the present disclosure provides an information acquisition method, executed by a terminal, including:

[0069] Step S102: Receive a first signal based on the generated information and / or sequence mapping relationship;

[0072] In some embodiments, the first signal can be understood as a signal carrying target indication information.

[0073] It should be noted that, in this embodiment of the present disclosure, the first signal is received based on the generation information and / or sequence mapping relationship of the first sequence and the second sequence, and wake-up indication information and / or transmission indication information are obtained; thereby, the wake-up indication information and / or transmission indication information can be obtained accurately, ensuring communication reliability.

[0074] In some embodiments, the generation information and / or sequence mapping relationship of the target sequence may be predefined by the protocol and / or sent to the terminal by the network device. Specifically, the network device may send the generation information and / or sequence mapping relationship of the target sequence to the terminal through at least one of Radio Resource Control (RRC) signaling, System Information Block (SIB, for example, SIB X) signaling, downlink data, and downlink control signals.

[0075] In some embodiments, under one implementation, the first signal in this disclosure embodiment may be the LP-WUS of the wake-up terminal.

[0076] In some embodiments, in one implementation, the first signal is generated jointly by the first sequence and the second sequence as follows: the first signal is generated by scrambling the first sequence to at least one target position of the second sequence;

[0077] The target location includes at least one of the following:

[0078] The OOK symbol represents the resource location that is ON, at least one frequency point of FSK, at least one phase of QPSK, the resource location where the information bit is 1, the resource location where the encoded transmission bit is 1 (the encoding can be Manchester encoding or other encoding methods), and the resource location where the transmission bit is 1.

[0079] In some embodiments, in another implementation, a first signal is associated with at least one first sequence set, the first sequence set including at least one first sequence, the at least one first sequence being scrambled at at least one target location of a second sequence.

[0080] It should be noted that a first signal associated with at least one first sequence set may be pre-agreed and / or configured by the network device.

[0081] In some embodiments, the sequence type of the first sequence in the first sequence set includes at least one of the following: ZC sequence, GOLD sequence, M sequence, Walsh sequence, and other random sequence.

[0082] In some embodiments, under one implementation method, the specific implementation of obtaining the target indication information includes:

[0083] By receiving at least one of the following: the first sequence determined by the first sequence, the first sequence in the first sequence set, and the first sequence transmission resource location, the target indication information carried by the first signal is obtained.

[0084] The first sequence transmission resource location includes at least one of the following: at least one target location where the first sequence is scrambled to the second sequence, the time domain resource location where the first sequence is located, and the frequency domain resource location where the first sequence is located.

[0085] It should be noted that the target indication information carried by the first signal is determined by at least one of the following: the first sequence set information, the first sequence in the first sequence set, and the location of the first sequence transmission resource.

[0086] In some embodiments of this disclosure, the following situations may exist:

[0088] In this case, the target indication information can be determined by at least one of the following: a first sequence set, a first sequence in the first sequence set, the time domain resource location of the first sequence, and the frequency domain resource location of the first sequence.

[0089] Scenario 2: The first sequence set and at least one target position scrambled from the first sequence to the second sequence jointly carry all the target indication information;

[0090] In this case, the target indication information can be determined by at least one of the following: a first sequence set, a first sequence in the first sequence set, or a target position of the first sequence scrambled to the second sequence.

[0091] In some embodiments, the first sequence set and at least one first sequence in the first sequence set mentioned in this disclosure may be configured and / or pre-agreed upon by a network device.

[0092] In some embodiments, under one implementation, the first sequence set satisfies at least one of A11-A13:

[0093] A11. At least one first sequence set carries target indication information for at least one terminal group, and the first sequence and / or the first sequence transmission resource location in the first sequence set carries target indication information for at least one terminal in the terminal group.

[0094] It should be noted that this approach can be understood as corresponding to scenario one above, where the first sequence set independently carries all the target indication information. In this case, the first sequence set carries the target indication information of the terminal group, and at least one of the first sequence, the time-domain resource location of the first sequence, and the frequency-domain resource location of the first sequence carries the target indication information of the terminals within the terminal group.

[0095] In some embodiments, for a first signal associated with a first sequence set, the generation information of the first sequence in the first sequence set is related to at least one of the following: the encoding information of the second sequence, the number of terminals associated with the target object, the number of terminal groups associated with the target object, the type of the first signal, the sequence information of the second sequence, the waveform information of the second sequence, the number of the first sequence, the terminal index, the terminal group index, the paging opportunity (PO) index, the paging frame (PF) index, the cell index, the transmission resource location of the first sequence, the time domain resource location of the first sequence, and the frequency domain resource location of the first sequence.

The waveform information of the second sequence includes, but is not limited to, at least one of the following: OOK waveform, FSK waveform, QPSK waveform, M value, waveform type (e.g., OOK type), and subcarrier spacing (SCS).

[0098] A12. At least one first sequence set, at least one first sequence in at least one first sequence set, and at least one of the first sequence transmission resource locations carry target indication information of the second sequence, wherein the target indication information of the second sequence includes at least one of the following: terminal index, terminal group index, code point value of the second sequence, total number of second sequences, total number of target indication information of the second sequence, payload size of the second sequence, and index information of the second sequence.

[0099] In some embodiments, for a first signal associated with a first sequence set, the generation information of the first sequence in the first sequence set is related to at least one of the following: the encoding information of the second sequence, the sequence information of the second sequence, the cell index (in some embodiments, the cell index can be understood as the index of the cell currently being communicated by the terminal), the time domain resource location of the second sequence, the frequency domain resource location of the second sequence, and the index information of the second sequence.

[0100] It should be noted that, in this case, since the first sequence carries the target indication information of the second sequence, the generation information of the first sequence is determined based on the relevant information of the second sequence. This relevant information refers to at least one of the following: the encoding information of the second sequence, the sequence information of the second sequence, the cell index, the time domain resource location of the second sequence, the frequency domain resource location of the second sequence, and the index information of the second sequence.

[0101] In some embodiments, for a first signal associated with multiple first sequence sets, the first sequence set carries first indication information of a second sequence, at least one first sequence in the first sequence set carries second indication information of the second sequence, the first indication information and the second indication information are used to determine the target indication information of the second sequence, and the generation information of the first sequence is related to the reception information of the first sequence set, the carrying information of the first sequence set, and at least one of the first sequences in the first sequence set;

[0102] The received information includes at least one of the following: a set index, the association between the target locations of the first sequence set and the second sequence; the first indication information of the second sequence is determined based on at least one of the following: the number of terminals associated with the target object, the number of terminal groups associated with the target object, the code point value of the second sequence, the index information of the second sequence, the number of the first sequence set, and the transmission resource location of the first sequence; the second indication information of the second sequence is determined based on at least one of the following: the number of terminals associated with the target object, the number of terminal groups associated with the target object, the code point value of the second sequence, the index information of the second sequence, the number of the first sequence set, the number of first sequences in the first sequence set, and the transmission resource location of the first sequence.

[0103] The information carried by the first sequence set refers to the first indication information of the second sequence.

[0104] The target object includes at least one of the following: a second sequence, a first sequence, and a first signal.

[0105] In this case, the target indication information is further divided into first indication information and second indication information, and different indication information is carried through sets and sequences.

[0106] A13. A first sequence set is associated with information of at least one second sequence segment, wherein a second sequence segment contains a second sequence of K3 bits, where K3 is greater than or equal to 1;

[0107] It should be noted that in this case, the second sequence is segmented, including multiple second sequence segments, and each first sequence set is associated with information from one or more second sequence segments.

[0108] In some embodiments, for a first signal associated with a first sequence set, the generation information of the first sequence in the first sequence set is related to at least one of the sequence information of the second sequence segment corresponding to the transmission resource location of the first sequence, the index of the second sequence segment corresponding to the transmission resource location of the first sequence, the time domain resource location of the second sequence, and the frequency domain resource location of the second sequence.

[0109] In some embodiments, for a first signal associated with multiple first sequence sets, the first sequence set carries second sequence segmentation index information, the first sequence in the first sequence set is associated with sequence information within the second sequence segment, and the generation information of the first sequence is related to at least one of the second sequence segmentation index information, the association relationship between the first sequence set and the target position of the second sequence.

[0110] In some embodiments, it should also be noted that, in the case where one first signal is associated with multiple sets of first sequences, the first sequences are mapped sequentially to the target positions of the second sequences according to the size of the index of the first sequence sets.

[0111] In some embodiments, it should also be noted that, in the case where one first signal is associated with multiple first sequence sets, the received information of the first sequence sets is determined by at least one of the following:

[0112] The sequence information of the second sequence, the number of first sequence sets associated with the first signal, the type of the first signal, the terminal index, and the terminal group index.

[0113] For example, a set index can be determined by at least one of the following:

[0114] Set index = ceil((number of terminals associated with the first signal + 1) / K1);

[0115] Set index = ceil(A / K1);

[0116] Set index = A mod K1;

[0117] Set index = A mod K1+1;

[0118] Set index = (number of terminals associated with the first signal + 1) mod K1;

[0119] Set index = (number of terminals associated with the first signal + 1) mod K1 + 1;

[0120] In some embodiments, ceil(*) is a rounding function, A represents the code point information of the second sequence, such as the code point value; K1 represents the number of first sequence sets associated with a first signal.

[0121] In some embodiments, for the implementations of A11-A13 described above, the terminal determines the index of the first sequence in the first sequence set associated with the first signal based on at least one of the following:

[0122] The first sequence set includes the number of first sequences, the sequence information of the second sequence, the number of terminal groups associated with the first signal, the number of bits of the symbol corresponding to the target waveform carried by an OFDM symbol, the cell index, the transmission resource location of the first sequence, the time domain resource location of the second sequence, and the frequency domain resource location of the second sequence.

[0123] For example, the index of the first sequence can be determined by at least one of the following:

[0124] The index of the first sequence in the set = (the number of terminals associated with the first signal + 1) mod K2;

[0125] The index of the first sequence in the set is A mod K2.

[0126] The index of the first sequence in the set = (the number of terminals associated with the first signal + 1) mod K2 + 1;

[0127] The index of the first sequence in the set = A mod K2+1;

[0128] Where K2 represents the number of first sequences contained in the first sequence set.

[0129] In some embodiments, under one implementation, the carrying information of the first sequence set is used to determine at least one of the following:

[0130] The first sequence generates cyclic shift, base sequence index information, initial value, scrambling code information, and the location of the first sequence transmission resources.

[0131] In some embodiments, under one implementation, the target position of scrambling K1 and / or K2 and / or the first sequence to the second sequence is determined by at least one of the following:

[0132] B11. Network equipment configuration and / or protocol agreement;

[0133] In this case, the target position of scrambling K1 and / or K2 and / or the first sequence to the second sequence can be directly indicated to the terminal by the network device; or it can be agreed upon by the protocol, that is, the protocol agrees on the value of K1 and / or K2 and / or the target position of scrambling the first sequence to the second sequence, where there can be multiple values ​​of K1 and K2, and when there are multiple values, they correspond to different values ​​of M.

[0134] B12. Determined based on configuration parameters, wherein the configuration parameters include at least one of the following: the number of bits of the symbol corresponding to the target waveform carried by an OFDM symbol, the length of the first sequence, the length of the second sequence, the length of the first signal, the coding rate, the number of terminals associated with the target object, the number of terminal groups associated with the target object, the number of sequences in a first sequence set, the number of terminals associated with a first sequence set, the number of terminal groups associated with a first sequence set, the target position of scrambling the first sequence to the second sequence, the number of times the first sequence is repeatedly transmitted, and the generator polynomial of the first sequence;

[0135] The target object includes at least one of the following: a second sequence, a first sequence, and a first signal.

[0136] In some embodiments, under one implementation, the determination based on configuration parameters includes at least one of the following:

[0137] B121. The number of bits of the symbol corresponding to the target waveform carried by an OFDM symbol and the length of the first signal are determined.

[0138] For example, K1 and / or K2 are determined by the length / M of the first signal, where M represents the number of bits of the symbol corresponding to the target waveform carried by an OFDM symbol.

[0139] For example, the value of K2 is determined based on the bit length of M and LP-WUS (e.g., the total number of codepoint values) and the value of K1, i.e., K2 = bit length of LP-WUS / M / K1.

[0140] B122. Based on the number of bits of the symbol corresponding to the target waveform carried by an OFDM symbol, different values ​​of the number of bits of the symbol corresponding to the target waveform carried by an OFDM symbol correspond to the number of first sequence sets associated with different first signals and / or the number of first sequences contained in the first sequence set.

[0141] This situation can be understood as the number of first sequence sets associated with the first signal and / or the number of first sequences contained in the first sequence set being determined by the number of bits of the symbol corresponding to the target waveform carried by an OFDM symbol.

[0142] B123, determined based on at least one of the following: the number of terminals associated with the target object, the terminal group associated with the target object, the number of terminals associated with a first sequence set, and the number of terminal groups associated with a first sequence set;

[0143] For example: K1 = the number of terminals associated with the first signal or the number of terminals associated with a first sequence set; K2 is determined based on the number of terminals associated with a first sequence set, for example, K2 = the number of terminals associated with a first sequence set or K2 = the number of terminals associated with a first sequence set + 1;

[0144] B124. The number of terminals associated with the target object, the number of terminal groups associated with the target object, and the number of bits of the symbol corresponding to the target waveform carried by an OFDM symbol are determined.

[0145] In some embodiments, K1 and K2 can be determined jointly using both protocol conventions and configuration parameter-based methods; for example, the protocol conventions stipulate that the value of K1 is the same as M, i.e., K1 = M, and the value of K2 is determined based on the number of sequences in the first sequence set and M, i.e., K2 = number of sequences in the first sequence set / M.

[0146] In some embodiments, under one implementation, the sequence mapping relationship of the first sequence is determined by at least one of the following:

[0147] The transmitted bit values ​​of the second sequence, the generator polynomial of the first sequence, the number of bits of the symbol corresponding to the target waveform carried by an OFDM symbol, and the transmission resource location of the first sequence.

[0148] For example, the sequence mapping relationship of the first sequence can be determined using Formula 1 and Formula 2.

[0149] Formula 1, X (k,l) (n)=f(n1)*g u,v (n); Formula 2,

[0150] Among them, X (k,l) (n) represents the sequence mapped on the target resource element (RE), the position of the target RE is determined based on k and l, n is the nth bit of the sequence, f(n1) represents the number of transmitted bits in the second sequence, and g u,v (n) represents the generator polynomial of the first sequence, k represents the carrier or RE index, l represents the OFDM symbol index; n1 = n / (number of valid REs of the first signal / M); q is the cyclic shift value.

[0151] In some embodiments, the meanings of u and v can be expressed in one of the following ways:

[0152] Method 1: u is the index of the first sequence set, and v is the index of the first sequence in the first sequence set;

[0153] Method 2: g u,v(n) is the generator polynomial of the ZC sequence, u is the ZC base sequence index, v is the subsequence index of the base sequence, and the value of u is determined by at least one of the following: the number of ZC base sequences, K1, K2, terminal index, and terminal group index; v can be determined based on one or more of the following: terminal index, K1, K2, terminal group index, the target position of the first sequence scrambling to the second sequence, the time domain resource position of the first sequence (e.g., may include but is not limited to slot index, symbol index, etc.), and M.

[0154] The following example illustrates the specific application of this embodiment, using the first sequence as a sequence generated from an OFDM waveform and the second sequence as a sequence generated from an OOK waveform, with the base station transmitting wake-up indication information to the terminal.

[0155] Application Scenario 1: The first sequence set carries the wake-up indication information of the terminal group.

[0156] Specifically, the main implementation process includes:

[0157] Step S111: The terminal obtains the generation information and / or sequence mapping relationship of the first sequence and the second sequence, and obtains wake-up indication information.

[0158] In some embodiments, a first sequence and a second sequence generate an LP-WUS carrying wake-up indication information; an LP-WUS is associated with at least one set of first sequences, and at least one first sequence in the first sequence set is scrambled at at least one target position of the second sequence;

[0159] In some embodiments, the target location includes at least one of the following: a resource location indicated by an OOK symbol, at least one frequency point of FSK, at least one phase of QPSK, a resource location with an information bit of 1, a resource location with a transmitted bit of 1 after encoding, and a resource location with a transmitted bit of 1.

[0160] In some embodiments, a target location of a second sequence is associated with at least one set of first sequences, and a first sequence from the first set of first sequences is scrambled at the target location of the second sequence.

[0161] In some embodiments, the first sequence set and at least one first sequence in the first sequence set may be pre-configured by the base station and / or pre-defined by the protocol.

[0162] In some embodiments, LP-WUS can be configured by the base station and / or predefined by the protocol with K1 (K1>=1) sets of first sequences. Each set of first sequences contains K2 first sequences, and each first sequence carries wake-up indication information for at least one terminal or terminal group. The generation information of the first sequences, the method of carrying the wake-up indication information, and the sequence mapping method are as follows:

[0163] Specifically, the method for determining K1 and / or K2 includes:

[0164] Method 1: The base station displays the instruction via configuration information;

[0165] Specifically, the base station displays at least one of the following related information: set index information, number of sequences in the set (K2), number of bits of OOK symbols carried by an OFDM symbol (hereinafter represented by M), number of associated OOK ONs, number of repeated transmissions of the first sequence, and length of the first sequence.

[0166] In particular, if LP-WUS is associated with only one set of first sequences, the base station configuration information can be configured to specify only the number of first sequences associated with LP-WUS.

[0167] Method 2: Determine the values ​​of K1 and / or K2 based on the predefined protocol. There can be multiple values ​​for K1 and K2, and when there are multiple values, they correspond to different values ​​of M.

[0168] Method 3: Based on M, the length of LP-WUS (e.g., the total number of codepoint values), K1 determines K2. For example, K2 = length of LP-WUS / M / K1.

[0169] Method 4: Based on the number of terminal groups associated with LP-WUS, the number of terminal groups associated with a first sequence set determines K1, for example, K1 = number of terminal groups associated with LP-WUS / number of terminals associated with a first sequence set; K2 is determined based on the number of terminal groups associated with a first sequence set, for example, K2 = number of terminal groups associated with a first sequence set or K2 = number of terminal groups associated with a first sequence set + 1;

[0170] Method 5: The value of K1 is predefined to be the same as that of M (K1 = M). The value of K2 is determined based on the base station configuration information or the number of sequences in the first sequence set predefined by the protocol and M. For example, K2 = number of sequences in the first sequence set / M.

[0171] Specifically, at least one first sequence set carries wake-up indication information for at least one terminal group, and the first sequence in the first sequence set carries wake-up indication information for at least one terminal within this terminal group, including the following two schemes:

[0172] Option 1: One LP-WUS is associated with a first sequence set (K1=1), and the relevant information of the first sequence and / or the frequency domain resource location of the first sequence and / or the time domain resource location of the first sequence together carry the terminal group information indicated by the LP-WUS;

[0173] In some embodiments, the relevant information of the first sequence includes, but is not limited to: the index information of the first sequence set in which the sequence is located, the initial value of the first sequence generation, the base sequence expression of the first sequence generation, the length of the first sequence, the cyclic shift value of the first sequence generation, the index information of the base sequence of the first sequence generation, and at least one of the scrambling sequences in the first sequence generation.

[0174] One LP-WUS is associated with K2 first sequences. The first sequences are sequentially scrambled at the target positions of the second sequences. The method for carrying wake-up indication information and scrambling the second sequences can be one of the following:

[0175] Method 1: A first sequence carries wake-up indication information for floor (number of terminal groups associated with LP-WUS / K2) or ceil (number of terminal groups associated with LP-WUS / K2). At the target position of each second sequence, the first sequence carrying the wake-up indication information is scrambled in sequence. The same first sequence or different first sequences can be transmitted at each target position.

[0176] Method 2: The number of terminal groups associated with LP-WUS is divided into K2 terminal group sets. Each terminal group set contains floor(number of terminal groups associated with LP-WUS / K2) or ceil(number of terminal groups associated with LP-WUS / K2) terminal groups. A first sequence carries the wake-up indication information of the terminal groups under a terminal group set. At the target position of each second sequence, the first sequence carrying the wake-up indication information is scrambled in sequence. At each target position, the same first sequence can be transmitted (the woken-up terminal groups belong to the same terminal group set), or different first sequences can be transmitted (the woken-up terminal groups belong to different terminal group sets).

[0177] Method 3: The number of terminal groups associated with LP-WUS is divided into P terminal group sets. Each terminal group set is associated with at least one target location of a second sequence (e.g., the resource location of an OOK ON symbol). The first sequence scrambled at the target location of the second sequence carries wake-up indication information of at least one terminal group in the terminal group set. The value of P can be configured by the base station and / or predefined by the protocol. In some embodiments, the value of P can be related to at least one of the following: the length of the second sequence, the total number of codepoints in the second sequence, the number of terminal groups indicated by LP-WUS, the coding rate of the second sequence, the number of first sequences in the first sequence set, the length of the first sequence, and the value of M.

[0178] Method 4: K2 first sequences each carry wake-up indication information for K2 terminal groups. The wake-up indication information for the remaining terminal groups associated with LP-WUS is determined based on the time resource location and / or the frequency resource location of the second sequence and / or the first sequence.

[0179] Method 5: K2 first sequences respectively carry the status information of wake-up indication information of K2 terminals or terminal groups. The status information of the wake-up indication information is related to at least one of the following: terminal index, terminal group index, terminal wake-up status (wake-up or sleep), and wake-up information level (terminal level, terminal group level, Common).

[0180] Option 2: One LP-WUS is configured with multiple (K1>1) first sequence sets. The first sequence set and / or the resource location associated with the first sequence set and / or the second sequence resource associated with the first sequence set carry wake-up indication information. The first sequence in the first sequence set, the target location of the first sequence scrambled to the second sequence, the time domain resource location of the first sequence, and the frequency domain resource location of the first sequence carry terminal wake-up indication information within the terminal group.

[0181] In some embodiments, the K1 first sequence sets may be configured by the base station and / or pre-agreed upon by the protocol.

[0182] In some embodiments, the set index and terminal index of the first sequence set associated with the LP-WUS transmitted by the base station, K1, the type of LP-WUS (e.g., it can be terminal-specific, terminal-group-specific, or terminal-common), the terminal group index, the target location for scrambling the first sequence to the second sequence, and at least one of the time-domain resource location and the frequency-domain resource location of the first sequence are related. Specifically, the first sequence set index can be determined in the following manner:

[0183] Method 1: The set index of the first sequence set = floor(terminal index / K1) or floor(terminal index / K1)+1 or Ceil(terminal index / K1) or Ceil(terminal index / K1)-1;

[0184] Method 2: The set index of the first sequence set = floor(target position of the first sequence to the second sequence / K1) or floor(target position of the first sequence to the second sequence / K1) + 1 or Ceil(target position of the first sequence to the second sequence / K1) or Ceil(target position of the first sequence to the second sequence / K1) - 1;

[0185] Method 3: The set index of the first sequence set = floor(OFDM symbol position of the first sequence / K1) or floor(OFDM symbol position of the first sequence / K1)+1 or Ceil(OFDM symbol position of the first sequence / K1) or Ceil(OFDM symbol position of the first sequence / K1)-1; the generation information of the first sequence in the set and the number of sequences in the set K2, the terminal group index, the terminal index, the length of the first sequence, the number of bits M of the OOK symbols carried by one OFDM symbol, the cell index, the transmission resource position of the first sequence, the target position of the first sequence scrambling the second sequence, the time resource position information of the first sequence, and the frequency domain resource position information of the first sequence are related to at least one of the following:

[0186] In some embodiments, the first sequence may be mapped sequentially to the target positions of the second sequence based on the sequence set index.

[0187] In some embodiments, the time-frequency resource mapping relationship of the first sequence and / or LP-WUS can be based on the following formula X (k,l) (n)=f(n1)*g u,v (n) Sure.

[0188] Step S112: The terminal receives the first sequence and / or the second sequence carried by the first signal and obtains wake-up indication information.

[0189] Application Scenario 2: At least one first sequence set, at least one first sequence from at least one first sequence set, and at least one item from the first sequence transmission resource location carry wake-up indication information for the second sequence.

[0190] Specifically, the main implementation process includes:

[0191] Step 211: The terminal obtains the generation information and / or sequence mapping relationship of the first sequence and the second sequence, and obtains wake-up indication information.

[0192] In some embodiments, a first sequence and a second sequence generate an LP-WUS carrying wake-up indication information; a wake-up signal is associated with at least one set of first sequences, and at least one first sequence in the set of first sequences is scrambled at at least one target location of the second sequence;

[0193] In some embodiments, the target location includes at least one of the following: a resource location indicated by an OOK symbol, at least one frequency point of FSK, at least one phase of QPSK, a resource location with an information bit of 1, a resource location with a transmitted bit of 1 after encoding, and a resource location with a transmitted bit of 1.

[0194] In some embodiments, a target location of a second sequence is associated with at least one set of first sequences, and a first sequence from the first set of first sequences is scrambled at the target location of the second sequence.

[0195] In some embodiments, the first sequence set and at least one first sequence in the first sequence set may be pre-configured by the base station and / or pre-defined by the protocol.

[0196] In some embodiments, LP-WUS can be configured by the base station and / or predefined by the protocol with K1 (K1>=1) sets of first sequences. Each set of first sequences contains K2 first sequences, and each first sequence carries partial information of the codepoint indicated by the second sequence. The generation information of the first sequence, the method of carrying wake-up indication information, and the sequence mapping method are as follows:

[0197] Specifically, the method for determining K1 and / or K2 includes:

[0198] Method 1: The base station displays the instruction via configuration information;

[0199] Specifically, the base station displays at least one of the following related information: set index information, number of sequences in the set (K2), number of bits M of OOK symbols carried by an OFDM symbol, number of associated OOK ONs, number of repeated transmissions of the first sequence, and length of the first sequence.

[0200] In particular, if LP-WUS is associated with only one set of first sequences, the base station configuration information can be configured to specify only the number of first sequences associated with LP-WUS.

[0201] Method 2: Determine the values ​​of K1 and / or K2 based on the predefined protocol. There can be multiple values ​​for K1 and K2, and when there are multiple values, they correspond to different values ​​of M.

[0202] Method 3: Based on M, the bit length of LP-WUS (e.g., the total number of codepoint values), K1 determines K2. For example, K2 = bit length of LP-WUS / M / K1.

[0203] Method 4: Based on the number of terminal groups associated with LP-WUS, the number of terminal groups associated with a first sequence set determines K1, for example, K1 = number of terminal groups associated with LP-WUS / number of terminals associated with a first sequence set; K2 is determined based on the number of terminal groups associated with a first sequence set, for example, K2 = number of terminals associated with a first sequence set or K2 = number of terminal groups associated with a first sequence set + 1;

[0204] Method 5: The value of K1 is predefined to be the same as that of M (K1 = M). The value of K2 is determined based on the base station configuration information or the number of sequences in the first sequence set predefined by the protocol and M. For example, K2 = number of sequences in the first sequence set / M.

[0205] Specifically, at least one first sequence carrying at least one second sequence of wake-up indication information includes the following two schemes:

[0206] Option 1: An LP-WUS signal is configured with a first sequence set (K1=1). The relevant information of the first sequence and / or the target position of the first sequence scrambled to the second sequence and / or the frequency domain resource position of the first sequence and / or the time domain resource position of the first sequence together carry the wake-up indication information carried by the second sequence.

[0207] In some embodiments, the relevant information of the first sequence includes, but is not limited to: the index information of the first sequence set in which the sequence is located, the initial value of the first sequence generation, the base sequence expression of the first sequence generation, the length of the first sequence, the cyclic shift value of the first sequence generation, the index information of the base sequence of the first sequence generation, and at least one of the scrambling sequences in the first sequence generation.

[0208] The wake-up indication information carried by the second sequence includes, but is not limited to, at least one of the following: codepoint value, total number of codepoints, sequence index corresponding to the codepoint, and codepoint generation information (including, but not limited to, at least one of the following: initial value of sequence generation, cyclic shift value of sequence, base sequence index of sequence generation, and length of sequence).

[0209] In some embodiments, one LP-WUS is associated with K2 first sequences, and the first sequences are sequentially scrambled at target positions of the second sequences. The method for carrying wake-up indication information and scrambling the second sequences can be one of the following:

[0210] Method 1: A sequence carries wake-up information for floor (second sequence code point information / K2) or ceil (second sequence code point information / K2) terminal groups. At each target position of the second sequence, a first sequence carrying wake-up indication information is scrambled in sequence. The same first sequence or different first sequences can be transmitted at each target position. The second sequence code point information can be codepoint_value or the total number of codepoints.

[0211] Method 2: The codepoint information associated with LP-WUS is divided into K2 codepoint sets. Each codepoint set contains floor (total number of second sequence codepoints / K2) or ceil (total number of second sequence codepoints / K2) terminal groups. One sequence is associated with wake-up indication information under one terminal group. At the target position of each second sequence, the first sequence carrying the wake-up indication information is scrambled in sequence. The same first sequence can be transmitted at each target position, or different first sequences can be transmitted.

[0212] Method 3: K2 first sequences each carry the information carried by the code points of K2 second sequences. The indication information carried by the remaining (K3-K2) code points of the second sequence is determined based on the second sequence, where all the indication information of the second sequence is carried by K3 code points.

[0213] Option 2: One LP-WUS is configured with multiple (K1>1) first sequence sets, each first sequence set carrying first indication information of a second sequence, and at least one first sequence in the first sequence set carrying second indication information of the second sequence, wherein the first indication information and the second indication information are used to determine the wake-up indication information of the second sequence.

[0214] In some embodiments, the K1 first sequence sets may be configured by the base station and / or pre-agreed upon by the protocol.

[0215] In some embodiments, the second sequence carries first indication information and the second indication information is related to the code point information of the second sequence. The explanation in Detail Scheme 1 will not be repeated here.

[0216] In some embodiments, the set index of the first sequence set associated with the LP-WUS transmitted by the base station, determined by the terminal, can be determined based on at least one of the following: terminal index, K1, type of LP-WUS (subgroup-specific, subgroup-set-specific, or Common), codepoint_value, and total number of codepoints.

[0217] The set index of the first sequence set = floor(codepoint_value / K1) or floor(codepoint_value / K1)+1 or Ceil(codepoint_value / K1) or Ceil(codepoint_value / K1)-1 or floor(codepoint_index / K1) or floor(codepoint_index / K1)+1 or Ceil(codepoint_index / K1)-1.

[0218] In some embodiments, the generation information of the first sequence (index information, cyclic shift information, base sequence index, initial value of sequence generation) is related to at least one of the following: the number of sequences K2 in the first sequence set, the terminal group index, the terminal index, the sequence length, the number of bits M of the OOK symbol carried by one OFDM symbol, the cell index, the target position of the first sequence scrambling to the second sequence, the time resource location information of the first sequence, the frequency domain resource location information of the first sequence, and the second indication information of the second sequence terminal.

[0219] For example, the generation information of the first sequence = the codepoint_value of the first sequence mod K2 or the codepoint_value of the first sequence mod K2+1 or the codepoint_index of the first sequence mod K2 or the codepoint_index of the first sequence mod K2+1;

[0220] In some embodiments, the first sequence may be mapped sequentially to the target positions of the second sequence based on the sequence set index.

[0221] In some embodiments, the time-frequency resource mapping relationship of the first sequence and / or LP-WUS signal can be based on the following formula X. (k,l) (n)=f(n1)*g u,v (n) Sure.

[0222] Step 211: The terminal receives the first sequence and / or the second sequence carried by the first signal and obtains wake-up indication information.

[0223] Application Scenario 3: The first sequence set is associated with information from at least one second sequence segment.

[0224] Specifically, the main implementation process includes:

[0225] Step 311: The terminal obtains the generation information and / or sequence mapping relationship of the first sequence and the second sequence, and obtains wake-up indication information.

[0226] In some embodiments, a first sequence and a second sequence generate an LP-WUS carrying wake-up indication information; a wake-up signal is associated with at least one set of first sequences, and at least one first sequence in the set of first sequences is scrambled at at least one target location of the second sequence;

[0227] In some embodiments, the target location includes at least one of the following: a resource location indicated by an OOK symbol, at least one frequency point of FSK, at least one phase of QPSK, a resource location with an information bit of 1, a resource location with a transmitted bit of 1 after encoding, and a resource location with a transmitted bit of 1.

[0228] In some embodiments, a target location of a second sequence is associated with at least one set of first sequences, and a first sequence from the first set of first sequences is scrambled at the target location of the second sequence.

[0229] In some embodiments, the first sequence set and at least one first sequence in the first sequence set may be pre-configured by the base station and / or pre-defined by the protocol.

[0230] In some embodiments, LP-WUS may be configured by the base station and / or the protocol may predefine K1 (K1>=1) sets of first sequences, each set of first sequences containing K2 first sequences, and the first sequences in the set of first sequences are associated with sequence information within the second sequence segment.

[0231] In some embodiments, the first sequence set carries one or more OOK sequence segment index information (LP-WUS includes K OOK sequence segments, the number of segments can be related to M), an OOK sequence segment includes K1 OOK symbols, and an LP-WUS can be configured with one or more first sequence sets.

[0232] Specifically, it includes the following two options:

[0233] Option 1: One LP-WUS configuration is a first sequence set, which carries the segmentation index information of the second sequence;

[0234] In some embodiments, the number of segments in LP-WUS can be configured by the base station or predefined by the protocol; in some embodiments, the number of segments in LP-WUS can be determined based on one of the following rules:

[0235] Rule 1: Based on M, it can be the bit length of LP-WUS / M, where M=1 means no segmentation and M=2 means segmentation;

[0236] Rule 2: The number of terminals is determined based on the size of the first sequence set and the number of terminals indicated by LP-WUS. It can be ceil((N_subgroup+N2) / size of the first sequence set), where N_subgroup represents the number of terminals, N2 is determined based on predefined rules or protocol conventions, and N2 is related to the sequence type of the first sequence. This sequence type can be terminal-specific and / or terminal group-specific and / or common to all terminals.

[0237] Example 1: If the first sequence only carries wake-up indication information for Subgroup specific and Common, then N2 = 1;

[0238] Example 2: If the first sequence carries wake-up indication information for Subgroup specific, Subgroup set specific and Common, then N2 = 1 + number of subgroup sets or N2 = 1 + 2^number of subgroup sets.

[0239] In some embodiments, the ON / OFF pattern information within the segment is carried on the OOK ON symbol contained in OOK Segment#i (0<=i<=K-1);

[0240] For example, LP-WUS is configured with Manchester coding or other coding, and the information carried by the segment and the OOK before encoding is related; (segment overlaid is repeated on multiple ONs on a single segment in the encoded sequence), where Seq_1 to 4 can come from the same set of first sequences or from different sets of first sequences, as shown in Table 1:

[0241] Table 1. Correspondence between segmented index and ON / OFF pattern information.

[0242] For example, LP-WUS does not have Manchester coding configured. The second sequence carries the wake-up terminal index. An OOK segment contains some index bits. The first sequence carries some subgroup index information contained in the Overlaid OOK segment. (If Manchester coding is not used when transmitting the index, the number of 0s and 1s is related to the wake-up information and multiple segments are not required.) As shown in Table 2, Seq_1 to 3 can come from the same set of first sequences or from different sets of first sequences.

[0243] Table 2. Correspondence between Terminal Index, Segment Index, and OFDM Segment

[0244] For example, if LP-WUS is not configured with Manchester coding, the terminal obtains wake-up indication information based on the resource location of the second sequence scrambled by the first sequence and / or the first sequence and / or the set of the first sequences, as shown in Table 2.

[0245] For example, a 4-bit second sequence is divided into two segments, each consisting of a 2-bit second sequence. The correspondence between the information of each second sequence segment and the first sequence is shown in Tables 3 and 4.
