Description

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

[0001] This disclosure claims priority to Chinese Patent Application No. 202510108605.0, 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 can receive wake-up information and / or cell index information carried by signals generated from at least one of the following waveforms in a low-power state: 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).

[0047] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0048] The terms “first,” “second,” etc., used in this disclosure and in the claims are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this disclosure described herein may be implemented, for example, in sequences other than those illustrated or described herein.

[0049] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship. In this disclosure, the term "multiple" refers to two or more objects, and other quantifiers are similar.

[0050] In this disclosure, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0051] The following is a brief explanation of the relevant concepts mentioned in this disclosure.

[0052] I. Generation of Low-Power Wake-up Signal (LP-WUS)

[0053] The LP-WUS research project focuses on the generation of LP-WUS and Low Power Synchronizing (LP-SS) signals based on Orthogonal Frequency Division Multiplexing (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 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 the conference.

[0054] OOK-1 waveform: One OFDM symbol corresponds to a single-bit. The method of mapping LP-WUS to a subcarrier (SC) is as follows:

[0055] OOK=1 means that all SCs are used for modulation;

[0056] OOK=0 means that all SCs have zero power (from the baseband perspective).

[0057] 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.

[0058] II. Time-Frequency Mapping Method for NR Signals

[0059] The time-frequency mapping rule for NR signals generates a fixed-length sequence based on the size of the signal transmission resources. This sequence is then sequentially mapped onto the resource elements (REs) of the transmission resources according to predefined mapping rules. The time-frequency mapping rule is related to the frequency domain RE location of the transmission resource containing the signal, the time domain location within a slot on the OFDM symbol, and the signal transmission power.

[0060] The NR system lacks a time-frequency mapping rule for sequences jointly generated from OOK and OFDM waveforms. The time-frequency resource location in the joint waveform mapping depends not only on the transmission resource location but also on the information transmitted with both the OOK waveform and the OFDM sequence. The following issues need to be considered when designing the sequence generation rule:

[0061] 1) When an LP-WUS signal carries OFDM sequences that transmit different information and are repeatedly transmitted, it is necessary to study how to determine the location of the time-frequency resources mapped to the repeated transmission sequences and the location of the time-frequency resources mapped to the OFDM sequences that transmit different information.

[0062] 2) When the OOK waveform parameter M>1, some REs on an OFDM symbol have a fixed input power of 0. If we want to ensure that the low power signal transmission power remains unchanged, the transmission power is dynamically adjusted based on different M values ​​and encoding methods. How to design the power allocation factor in the time-frequency mapping relationship needs to be studied.

[0063] To address the above issues, this disclosure proposes a time-frequency resource mapping method applicable to low-power wake-up signals and low-power synchronization signals, which can at least determine the time-frequency resource location and the power allocation factor of each RE based on at least one OFDM sequence carried by LP-WUS or LP-SS.

[0064] 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.

[0065] 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.

[0066] This disclosure provides an information acquisition and transmission method, apparatus, terminal, and network device to accurately acquire wake-up information and / or cell index-related information.

[0067] 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.

[0068] As shown in Figure 1, this embodiment of the present disclosure provides an information acquisition method, executed by a terminal, including:

[0069] Step S101: Obtain the resource mapping relationship of the target sequence carried by the first signal;

[0070] Step S102: Receive the first signal at the resource location where the first signal's listening opportunity is located, according to the resource mapping relationship;

[0071] Step S103: Based on the first signal, obtain target information, the target information including: wake-up information and / or cell index related information;

[0072] The target sequence includes at least one of the following: a first sequence and a second sequence; the first sequence is a sequence generated based on a target waveform or a target modulation method, the target waveform includes at least one of the following: OOK waveform, FSK waveform, QPSK waveform, and the target modulation method includes at least one of the following: OOK modulation, FSK modulation, QPSK modulation; the second sequence is a sequence generated by at least one of OFDM waveform, CDM waveform, TDM waveform, and NOMA waveform.

[0073] It should be noted that, according to the resource mapping relationship of the target sequence carried by the first signal, the first signal is received at the resource location where the first signal is being monitored, and wake-up information and / or cell index related information are obtained; thereby, the wake-up information and / or cell index related information can be accurately obtained, ensuring communication reliability.

[0074] In some embodiments, the first signal can be understood as a signal carrying target information.

[0075] In some embodiments, under one implementation, the first signal in this disclosure embodiment can be either LP-WUS or LP-SS for waking up the terminal.

[0076] In some embodiments, under one implementation, the resource mapping relationship satisfies at least one of A11-A13:

[0077] A11. A listening opportunity includes at least one resource location, and a resource location carries a first sequence of bits and / or a second sequence of bits.

[0078] In some embodiments, a listening opportunity includes M×P resource locations, where P is the number of time units of the resource on which the listening opportunity persists; M is the number of bits of the target symbol transmitted per time unit of the resource or the number of bits of the first sequence transmitted per time unit of the resource; for example, if the second sequence is a sequence generated by an OFDM waveform, the time unit of the resource may refer to an OFDM symbol; if the second sequence is a sequence generated by a CDM waveform, the time unit of the resource may refer to a CDM symbol; if the second sequence is a sequence generated by a TDM waveform, the time unit of the resource may refer to a TDM symbol; if the second sequence is a sequence generated by a NOMA waveform, the time unit of the resource may refer to a NOMA symbol. For example, M is the number of bits of the target symbol transmitted per OFDM symbol or the number of bits of the first sequence transmitted per OFDM symbol; P is the number of OFDM symbols on which the listening opportunity persists.

[0079] In some embodiments, the target symbol mentioned in this disclosure includes, but is not limited to, at least one of the following: OOK symbol, FSK symbol, and QPSK symbol.

[0080] A12. An eavesdropping opportunity is divided into X resource groups, and each resource group includes Y resources. Each resource group transmits at least one first sequence and / or at least one second sequence after encoding at least one bit. X and Y are integers greater than or equal to 1.

[0081] In some embodiments, the temporal duration of the resource listening opportunity is a resource group, and the values ​​of X and Y are related to information of at least one first sequence; for example, the value of X is related to the waveform parameters of the target waveform (e.g., waveform parameter M), and the value of Y is related to L, where L is the length of the encoded first sequence or the length of the first sequence; for example, the value of X is equal to the waveform parameters of the target waveform, for example, Y = M, where M is the number of bits of the target symbol transmitted on an OFDM symbol or the number of bits of the first sequence transmitted on an OFDM symbol.

[0082] In some embodiments, the first bit of the first sequence is mapped onto a resource group, the value of X is related to L and / or R, Y is related to R, and R is the encoding rate of the first sequence; for example, Y = 1 / R; for example, X = L × R.

[0083] In some embodiments, the mapping method between the second sequence and the X resource groups includes at least one of A121-A122:

[0084] A121. A second sequence that maps the same information within a resource group, and a second sequence that maps different information between different resource groups, wherein the second sequence carries information of a first sequence of Q bits mapped on the resource group, where Q is an integer greater than or equal to 1;

[0085] In some embodiments, the information of the first sequence includes at least one of the following:

[0086] The wake-up information of the terminal, the wake-up information of the terminal group, the wake-up information of at least one terminal, the terminal associated with the first sequence or the indication information of the terminal, and the sequence representation numerical information of the first sequence, wherein the numerical information is at least 1 bit of decimal numerical information represented by the first sequence (e.g., 00-0, 01-1, 10-3, 11-4).

[0087] In some embodiments, the information of the second sequence referred to in this disclosure includes at least one of the following:

[0088] Encoding method, code rate, sequence length, at least one sequence generation parameter, number of terminals or number of terminal groups associated with the sequence.

[0089] In other words, in this case, all second sequences with the same information are mapped to the same resource group, while the second sequences mapped in different resource groups are different. For example, if there is at least one second sequence 1, at least one second sequence 2, and at least one second sequence 3, and there are a total of 3 resource groups, then resource group 1 maps to at least one second sequence 1, resource group 2 maps to at least one second sequence 2, and resource group 3 maps to at least one second sequence 3.

[0090] A122. A second sequence of different information is mapped within a resource group, and the second sequence of different information is repeatedly transmitted among X resource groups;

[0091] In other words, in this case, the second sequences mapped within the same resource group are different, and all the second sequences are mapped repeatedly in different resource groups; for example, if there are 2 second sequences 1, 2 second sequences 2 and 2 second sequences 3, and there are a total of 2 resource groups, then resource group 1 maps to 1 second sequence 1, 1 second sequence 2 and 1 second sequence 3, and resource group 2 maps to 1 second sequence 1, 1 second sequence 2 and 1 second sequence 3.

[0092] A13. At least one second sequence and at least one first sequence generate a time-domain sequence and / or frequency-domain sequence of the first signal based on a matching rule;

[0093] In some embodiments, the matching rule includes: a first sequence of length L2 bits and at least one second sequence of length L1 bits are expanded into a joint sequence of length L2 × L1 bits by a predefined rule, where L1 and L2 are integers greater than or equal to 1;

[0094] Wherein, L2 is related to at least one of the following: the number of bits of the target symbol transmitted in a time unit of a resource, the number of bits of the first sequence transmitted in a time unit of a resource, L3, R, and the number of terminals or terminal groups indicated by the first signal; L3 is the time domain duration of the resource; and R is the coding rate of the first sequence.

[0095] In some embodiments, the predefined rules include: each bit in the first sequence is expanded into an L1-bit sequence, the position of bit value 0 is expanded into an L1-bit all-zero sequence, and the position of bit value 1 is expanded into an L1-bit second sequence.

[0096] In some embodiments, the first sequence includes K1×K2 bits with a value of 1, which are expanded into K1×K2 second sequences according to the expansion rule. The K1 second sequences transmit different information, and the K2 second sequences transmit the same information. That is, K2 is the number of times the second sequence is repeated.

[0097] The expansion rule includes one of A131 and A132:

[0098] A131. The first bit position corresponding to the first sequence with a bit value of 1 is first expanded into K1 second sequences in sequence, and the remaining bit positions corresponding to the first sequence with a bit value of 1 are repeated K2-1 times.

[0099] This can be understood as follows: first, the bit position with the first bit value of 1 is expanded into K1 second sequences, and the subsequent bit positions with the first bit value of 1 are expanded by repeating the previous K1 sequences.

[0100] A132. The position of the Hth bit with a value of 1 in the first sequence is repeatedly extended to the ath second sequence, where H takes the value from K2×a to K2×(a+1)-1 and a takes the value from 0 to K1-1; or, H takes the value from K2×(a-1) to K2×a-1 and a takes the value from 1 to K1.

[0101] This situation can be understood as the bit position where each bit value is 1 is repeatedly extended by a second sequence.

[0102] In some embodiments, under one implementation, the resource mapping relationship is associated with at least one of the following:

[0103] At least one first sequence, at least one second sequence, information of the first sequence, information of the second sequence, index of the resource location in the listening opportunity, waveform parameters of the target waveform, encoding method, code rate, transmit power factor, resource group index, time-domain resource location of the listening opportunity, frequency-domain resource location of the listening opportunity, time-domain index, frequency-domain index, port number, and subcarrier spacing (SCS).

[0104] In some embodiments, the waveform parameters include, but are not limited to, at least one of the following: OOK type, M, Discrete Fourier Transform (DFT) size, Least Squares (LS) size, and SCS.

[0105] In some embodiments, for A11 above, the resource mapping relationship is related to at least one of the following:

[0106] At least one first sequence, at least one second sequence, information of the first sequence, information of the second sequence, index of the resource location in the listening opportunity, time domain index, frequency domain index, port number, SCS, and transmit power factor.

[0107] In some embodiments, for A12 above, the resource mapping relationship is associated with at least one of the following:

[0108] At least one first sequence, at least one second sequence, information of the first sequence, information of the second sequence, resource group index, waveform parameters of the target waveform, encoding method, code rate, transmit power factor, time domain index, frequency domain index, port number, and SCS.

[0109] In some embodiments, under one implementation, the time-domain location and / or frequency-domain location corresponding to the target resource index is associated with at least one of the following:

[0110] The time-domain location index of the listening opportunity, the frequency-domain location index of the listening opportunity, the target resource index, the number of bits of the target symbol transmitted in a time unit of a resource, and the number of bits of the first sequence transmitted in a time unit of a resource;

[0111] The target resource index can be any one of the following: the index of the listening opportunity, the index of the listening opportunity group, or the index within the listening opportunity group.

[0112] It should be noted that the target resource index ranges from 0 to M×P-1 or from 1 to M×P.

[0113] In some embodiments, under one implementation, for A11 and A12 above, a first sequence of the i-th or i+1-th bit is transmitted on resource index i, and / or, the one listening opportunity includes a second sequence mapped to the same and / or different resource locations; i is an integer greater than or equal to 0.

[0114] In some embodiments, under one implementation, the one listening opportunity includes a second sequence mapped to the same and / or different resource locations, including at least one of the following:

[0115] B11, A second sequence is repeatedly mapped to a resource location in at least one first sequence where the bit information value is 1;

[0116] For example, for A11, in this case, it refers to a second sequence repeatedly mapped to all resource locations that map specific first sequence bit information across M×P resource locations, as detailed in Expression 1:

[0117] Expression 1

[0118] Where k' = 1, 2, 3...; b(k') is the second sequence, a(i) is the value of the i-th bit of the first sequence, and β... LP The transmit power factor for the time-frequency mapping of the signal can be predefined or derived based on the target waveform configuration. For example, when M=1, β LP =β1, when M>1, β LP=β1×2; β1 is a pre-configured power value or a power offset value based on a reference signal, which can be one of LP-SS or Synchronization Signal and PBCH block (SSB); This represents the mapping sequence on the RE; k is the RE index information, l is the time unit index information, p is the port number, and μ is related to the SCS (SCS is 2). μ • 15 [kHz], u = 0 corresponds to SCS = 15 kHz, u = 1 corresponds to SCS = 30 kHz; and so on.

[0119] B12 and K1 second sequences transmitting different information are mapped to K2×K1 resource locations. The resource location is the resource location where the bit information in the first sequence is 1 or the target symbol in the first sequence represents an enabled resource location. K1 and K2 are integers greater than or equal to 1, and K2 represents the number of times the mapping is repeated.

[0120] For A11, K2×K1 is less than or equal to M×P.

[0121] In some embodiments, the K1 second sequences carrying different information are repeatedly mapped to resource locations of K2×K1 bit information mapped to the first sequences, including at least one of the following:

[0122] B121. First map K1 different second sequences once, then repeat the mapping K2-1 times for K1 different second sequences.

[0123] In this case, different second sequences are mapped first, and then the second sequences are mapped repeatedly.

[0124] B122. First, map the a-th second sequence K2 times, then map the (a+1)-th second sequence K2 times, where a = 1 to K1 or a = 0 to K1-1.

[0125] It should be noted that in this case, the K1 second sequences that transmit different information are mapped to resource locations where the bit information in the first sequence is 1 or where the target symbol in the first sequence represents an enabled resource location.

[0126] B13. A second sequence is repeatedly mapped in at least one first sequence to a target symbol representing an open resource location, the target symbol including at least one of the following: OOK symbol, FSK symbol, QPSK symbol;

[0127] For example, a second sequence repeatedly maps OOK symbols to open resource locations in at least one first sequence.

[0128] B14 and K1 second sequences transmitting different information are mapped to K1×K3+K4 resource locations. The resource location is the resource location where the bit information in the first sequence is 1 or the target symbol in the first sequence represents an enabled resource location. K1, K3, and K4 are integers greater than or equal to 1. K3 is the number of times at least one of the K1-K4 second sequences is repeatedly transmitted. The K4 second sequences are repeatedly transmitted K3+1 times.

[0129] B15 and K1 second sequences transmitting different information are mapped to K1+K5 resource locations. The resource location is the resource location where the bit information in the first sequence is 1 or the target symbol in the first sequence indicates that the resource is enabled. K1 and K5 are integers greater than or equal to 1. K5 is the number of times at least one of the K1 second sequences is repeatedly transmitted or the number of second sequences that are repeatedly transmitted among the K1 second sequences.

[0130] In some embodiments, under one implementation, the method further includes:

[0133] This can be understood as the transmission power factor being configured through configuration information sent by the network device.

[0134] D12. The transmit power factor on each RE is determined based on the transmit power offset of the reference signal and the power of the reference signal in the configuration information.

[0135] This situation can be understood as the network device not directly configuring the transmit power factor, but determining it through the transmit power offset and power of the reference signal configured in the configuration information.

[0138] D13. Determine the transmit power factor on each RE based on the reference power, the waveform parameters of the target waveform, and the coding information of the target waveform;

[0139] This situation can be understood as follows: the network device does not configure the transmission power factor; the terminal determines the transmission power factor by using the reference power, the waveform parameters of the target waveform, and the encoding information of the target waveform.

[0140] In some embodiments, under one implementation, the method further includes:

[0179] Step S12: The terminal determines the resource mapping relationship between the first sequence and the second sequence carried by LP-WUS;

[0180] In some embodiments, a listening opportunity (MO) is divided into M×P resources, where M is the number of bits of an OOK symbol transmitted on an OFDM symbol or the number of bits of an OOK sequence transmitted on an OFDM symbol; and P is the number of OFDM symbols that the listening opportunity continues for. One resource transmits 1 bit of a first sequence (abbreviated as OOK sequence) and / or one second sequence (OFDM sequence).

[0181] In some embodiments, the resource mapping relationship is associated with at least one of the following:

[0182] At least one first sequence, at least one second sequence, information of the first sequence, information of the second sequence, index of the resource location in the listening opportunity, and transmit power factor.

[0183] In some embodiments, the resource index i = 0 to M×P-1 or 1 to M×P, and the time-domain position and / or frequency-domain position corresponding to the resource index i are related to at least one of the time-domain position of MO, frequency-domain position, resource index i, the number of bits of the target symbol transmitted on an OFDM symbol, and the number of bits of the first sequence transmitted on an OFDM symbol.

[0184] The OFDM symbol position l corresponding to resource index i is: l = l0 + f(i), where l0 is the starting OFDM symbol position in the time slot where MO is located, and the value can be 0 to 13 or 1 to 14; f(i) is related to at least one of M, P, and predefined value G, and the relationship can be one or more of the following: rounding down, rounding up, modulo, addition, subtraction, multiplication, and division.

[0185] f(i) can be one of the following: f(i) = i - 1;

[0186] Where i = 1 to L1 or 0 to L1-1, L1 is the bit length after bit encoding of the OOK waveform or the transmission bit length. L1 can be determined by the base station or based on the information bit length, coding rate, M, and time domain duration. L1 = L2 / R, where L2 is the information bit length and R is the coding rate. Alternatively, L1 = M × L, where L is the time domain duration, which can be the number of OFDM symbols.

[0187] The frequency domain position k corresponding to resource index i is: Where k0 is the starting frequency domain position of MO, and g(i), t(i) are one or more of the following operations: rounding up M, P, first signal bandwidth XRB, DFT / LS size, modulo, addition, subtraction, multiplication, and division.

[0188] g(i) can be one of the following; g(i) = imod(N) × W × X / M; g(i) = imod(N) × L DFT / LS / M;

[0189] Where W represents the number of REs contained in an RB.

[0190] t(i) can be one of the following: t(i) = (imod(N) + 1) × W × X / M; t(i) = (imod(N) + 1) × L DFT / LS / M.

[0191] The first sequence (OOK sequence) transmitting the i-th or i+1-th bit on resource index i, and the second sequence (OFDM sequence) mapping the same or different on M×P resources, are divided into the following two cases:

[0192] Case 1: A second sequence is repeatedly mapped to all resource locations in M×P resources that map specific first sequence bit information. The expression can be one of the following:

[0193] Where, k'=1,2,3……; i=1~M×P;

[0194] Where, k'=1,2,3……; i=0~M×P-1;

[0195] Where b(k') is the second sequence, a(i) is the i-th bit of the first sequence, and β LP The transmit power factor for the time-frequency mapping of the signal can be predefined or configured based on the OOK waveform. M-related factors are used, such as β when M=1. LP =β1, when M>1, βLP = β1 × 2; β1 is a pre-configured power value or a power offset value based on a reference signal, and the reference signal can be one of LP-SS and SSB.

[0196] Case 2: K1 second sequences (OFDM sequences) that transmit different information are respectively repeatedly mapped to the resource positions that map specific first sequence bit information of K2 × K1 (K1 × K2 < M × P), and the mapping relationship can be one of the following methods:

[0197] Method 1: First map the sequences that transmit different information, and then transmit repeatedly. For example, the time-frequency mapping rule of 4 actual mapped resource positions is as follows:

[0198] where k' = 1, 2, 3...; Or i = 1 to M × P; i is the resource index, b y (k′) is an OFDM sequence, and there are a total of K1 sequences that transmit different information. k is the RE index information, l is the OFDM index information, p is the port number, and μ is related to SCS (SCS is 2 μ ·15 [kHz], u = 0 corresponds to SCS = 15 kHz, u = 1 corresponds to SCS = 30 kHz; and so on); β LP is the power factor of the signal time-frequency mapping, which can be predefined or configured based on the OOK waveform related to M. a(i) is the value of the i-th bit of the first sequence, and β LP is the transmission power factor of the signal time-frequency mapping, which can be predefined or derived based on the OOK waveform configuration. The reference signal can be one of LP-SS and SSB;

[0199] For example, in FIG. 2, taking M = 2 and P = 4 as an example, there are a total of 8 candidate OFDM scrambling opportunities. The OOK waveform uses 1 / 2 Manchester coding. For 4 actual mapped resource positions, if K1 = 2, then K2 = 2. The first OFDM sequence and the second OFDM sequence are sequentially mapped to 2 of the 4 candidate opportunities among the first 4 candidate opportunities. Among them, the different filled boxes in the first 4 columns in FIG. 2 represent different candidate opportunities, and the first OFDM sequence and the second OFDM sequence are sequentially mapped in the same mapping manner as the first 4 candidate opportunities for the last 4 candidate opportunities.

[0200] Method 2: First map one second sequence that transmits K2 identical information, and then map another second sequence, and so on; the time-frequency mapping rule is as follows: 2]

[0201] where k' = 1, 2, 3...; or i = 1 to M×P; i is the resource index, b y (k′) is an OFDM sequence, with a total of K1 sequences transmitting different information. k is the RE index information, l is the OFDM index information, p is the port number, and u is related to the SCS; β LP The power factor for the time-frequency mapping of the signal can be predefined or configured based on the OOK waveform. M-related factors, such as β when M=1. LP =β1, when M>1 β LP =β1×2; β1 is a pre-configured power value or a power offset value based on a reference signal, which can be one of LP-SS or SSB.

[0202] Step S13: The terminal receives LP-WUS and obtains wake-up information and / or cell index related information.

[0203] Application Scenario 2: Base station and terminal transmission of LP-WUS, using the aforementioned A12

[0204] Specifically, the main implementation process includes:

[0205] Step S21: The base station sends configuration information to at least one terminal to indicate a first signal to the terminal for waking it up;

[0206] It should be noted that the first signal is LP-WUS.

[0207] In some embodiments, the generation sequence of the first signal consists of a first sequence (hereinafter referred to as the OOK sequence) generated based on the OOK waveform and / or at least one second sequence (hereinafter referred to as the OFDM sequence) generated based on the OFDM waveform.

[0208] In some embodiments, the configuration information includes at least one of E21-E23:

[0209] E21 and OOK waveform configuration information include at least one of the following:

[0210] E211, OOK waveform types, such as OOK-1, OOK-2, OOK-4, etc.;

[0211] E212, the number of bits M of OOK symbols transmitted on an OFDM symbol;

[0212] E213, DFT / LS size.

[0213] E22, Generation information of the first sequence and / or the second sequence, the generation information including at least one of the following:

[0214] E221. Sequence type, which may include one of the following: M sequence, GOLD sequence, ZC sequence, Walsh sequence, Hardmard sequence, and PN sequence;

[0215] E222, Sequence generating polynomial;

[0216] E223, Sequence generation parameters: CS, root, initial sequence value;

[0217] E224, Sequence length;

[0218] E225, Encoding method: Manchester encoding, RM encoding;

[0219] E226, Encoding Rate.

[0220] E23. Time-frequency resource configuration information of the first signal, which includes at least one of the following:

[0221] E2301, Cycle;

[0222] E2302, Offset within the period;

[0223] E2303, offset from the target resource location, which can be: PO, PEI-O, or the start position of the DRX activation period;

[0224] E2304, Number of resource groups;

[0225] E2305, The number of resources within a resource group;

[0226] E2306, Duration;

[0227] E2307, Number of transmissions within one cycle;

[0228] E2308, Number of repeated transmissions;

[0229] E2309, bandwidth;

[0230] E2310, Starting frequency domain position;

[0231] E2311, Termination frequency domain position;

[0232] E2312, Protective belt spacing.

[0233] Step S22: The terminal determines the resource mapping relationship between the first sequence and the second sequence carried by LP-WUS;

[0234] An MO can be divided into X resource groups, and each resource group includes Y resources. Within a resource group, at least one bit first sequence (OOK sequence) and / or at least one second sequence (OFDM sequence) are transmitted. The resource group division method and the corresponding resource mapping relationship include one of the following methods:

[0235] Method 1: One OFDM symbol constitutes one resource group. The value of X is the same as the value of the OOK waveform parameter M, and the value of Y is the same as L (L represents the length of the encoded first sequence or the length of the first sequence). The resource mapping relationship is related to at least one of the following: at least one first sequence, at least one second sequence, information of the first sequence, information of the second sequence, resource group index, waveform parameters of the target waveform, encoding method, encoding rate, and transmission power factor.

[0236] Specifically, it can be:

[0237] For example, in the resource index (x, y), x takes values ​​from 0 to L-1 or 1 to L, and y takes values ​​from 0 to M-1 or 1 to M; the OFDM symbol index corresponding to the resource index (x, y) is l = l0 + x or l = l0 + x - 1, and the corresponding frequency domain position k is... or

[0238] For example, the resource index (x, y) maps to the OOK sequence information of the f(x, y) bit, where the sequence can be 0 or 1, and the relationship between f(x, y) and x, y can be one of the following: f(x, y) = x × M + y; f(x, y) = x × M + y - 1; f(x, y) = x × M + y + 1; f(x, y) = (x - 1) × M + y; f(x, y) = (x - 1) × M + y - 1; f(x, y) = (x - 1) × M + y + 1.

[0239] For example, the resource index (x, y) maps an OFDM sequence to the position where the OOK sequence bit is 1, and the number of OFDM sequences mapped is K1×K2, where K1 is the number of OFDM sequences transmitting different information and K2 is the number of OFDM sequences transmitting the same information. The time-frequency mapping relationship of OFDM sequences can be divided into the following two cases:

[0240] Scenario 1: First map K1 OFDM sequences that transmit different information, then repeat the mapping K2 times. The time-frequency mapping relationship can be one of the following:

[0241] Where k' = 1, 2, 3, ..., L1; or b t(k′) represents the OFDM sequence, where t takes values ​​from 0 to K1-1 or 1 to K1, corresponding to K1 OFDM sequences transmitting different information. L1 is the length of an OFDM sequence, configured by the base station or determined based on predefined rules. These predefined rules are related to at least one of the following: LP-WUS bandwidth x1 RB, M, DFT / LS size, and G (number of zeros padded, which can be 0 or other predefined values). For example, L1 = 12 × x1 / MG or DFT size / MG or LS size / MG. R is the OOK sequence coding rate. k is the RE index information, l is the OFDM index information, p is the port number, and μ is related to SCS (SCS is 2). μ • 15 [kHz], u = 0 corresponds to SCS = 15 kHz, u = 1 corresponds to SCS = 30 kHz; and so on; β LP The transmit power factor for the time-frequency mapping of the signal can be predefined or configured based on the OOK waveform. M-related factors are used, such as β when M=1. LP =β1, when M>1, β LP =β1×2; β1 is a pre-configured power value or a power offset value based on a reference signal, which can be one of LP-SS or SSB.

[0242] Scenario 2: Each OFDM sequence transmitting different information is first mapped K2 times and then mapped to the OFDM sequence transmitting different information. The time-frequency mapping relationship can be one of the following:

[0243] Where k' = 1, 2, 3, ..., L1; or b t (k′) represents the OFDM sequence, where t takes values ​​from 0 to K1-1 or 1 to K1, corresponding to K1 OFDM sequences transmitting different information; L1 is the length of an OFDM sequence, configured by the base station or determined based on predefined rules, which are related to at least one of the following: LP-WUS bandwidth X1 RB, M, DFT / LS size, G (number of zeros padded, which can be 0 or other predefined values); for example, L1 = 12 × X1 / MG or DFT size / MG or LS size / MG; R is the OOK sequence coding rate; k is the RE index information, l is the OFDM index information, p is the port number, μ is related to SCS; β LP The transmit power factor for the time-frequency mapping of the signal can be predefined or configured based on the OOK waveform. M-related factors are used, such as β when M=1. LP =β1, when M>1, β LP =β1×2; β1 is a pre-configured power value or a power offset value based on a reference signal, which can be one of LP-SS or SSB.

[0244] Method 2: The resource mapped to the first 1 bit of the OOK sequence is a resource group (Y = 1 / R, where R is the coding rate of the OOK sequence), then the number of resource groups X is L×R; the resource mapping relationship is related to at least one of the following: at least one first sequence, at least one second sequence, information of the first sequence, information of the second sequence, resource group index, waveform parameters of the target waveform, coding method, coding rate, and transmission power factor.

[0245] Specifically, it can be:

[0246] For example, in the resource index (x, y), x takes values ​​from 0 to L×M×R⁻¹ or 1 to L×M×R, and y takes values ​​from 0 to 1 / R⁻¹ or 1 to 1 / R; the OFDM symbol index corresponding to the resource index (x, y) is l = l₀ + g(x, y), and the corresponding frequency domain position k is... or or

[0247] g(x,y) can be one of the following:

[0248] U(x,y) can be one of the following: U(x,y)=(x / R+y)mod M; U(x,y)=(x / R+y)modM+1; U(x,y)=((x-1) / R+y)modM; U(x,y)=((x-1) / R+y)modM+1.

[0249] For example, the 1 / R bit sequence after encoding the OOK information sequence of the xth bit is mapped on the xth resource group. The encoding sequence and encoding rules are related: Manchester encoding with a 1 / 2 code rate. A resource group includes 2 resources. OOK information bit 1 corresponds to encoded bit 01, and OOK information bit 0 corresponds to encoded bit 10. The 2 bits of information after encoding are mapped to all REs corresponding to the 2 resources in sequence.

[0250] For example, the resource index (x, y) maps the position where the OOK sequence encoding bit is 1 to the OFDM sequence. The time-frequency mapping relationship of the OFDM sequence can be divided into one of the following cases:

[0251] Scenario 1: A resource group has only one OFDM sequence mapping position (Manchester coding at 1 / 2 code rate). The OFDM sequence mapping position within the group is based on the fact that the position of bit 1 in the OOK encoded sequence is the same. X resource groups transmit K1×K2 OFDM sequences. This can be done by transmitting different sequences first and then repeating them. For example, it can be one of the following:

[0252] Where k' = 1, 2, 3, ..., L1; t = x mod K1 or t = x mod K1+1.

[0253] Alternatively, it can involve transmitting the same sequence repeatedly followed by different sequences. For example, it could be one of the following:

[0254] Where k' = 1, 2, 3, ..., L1; or

[0255] Where a(x,y) is the value of the y-th bit after encoding the x-th information bit of the OOK sequence; b t (k′) represents the OFDM sequence, where t takes values ​​from 0 to K1-1 or 1 to K1, corresponding to K1 OFDM sequences transmitting different information. L1 is the length of an OFDM sequence, configured by the base station or determined based on predefined rules. The predefined rules are related to at least one of the following: LP-WUS bandwidth x1 RB, M, DFT / LS size, and G (number of zeros padded, which can be 0 or other predefined values). For example, L1 = 12 * x1 / MG or DFT size / MG or LS size / MG. R is the OOK sequence coding rate. k is the RE index information, l is the OFDM index information, p is the port number, and μ is related to SCS (SCS is 2). μ • 15 [kHz], u = 0 corresponds to SCS = 15 kHz, u = 1 corresponds to SCS = 30 kHz; and so on; β LP The transmit power factor for the time-frequency mapping of the signal can be predefined or configured based on the OOK waveform. M-related factors are used, such as β when M=1. LP =β1, when M>1, β LP =β1×2; β1 is a pre-configured power value or a power offset value based on a reference signal, which can be one of LP-SS or SSB.

[0256] Scenario 2: There are multiple OFDM sequence mapping locations on a set of resources. OFDM sequences are repeatedly mapped within a resource group; different OFDM sequences are mapped within different resource groups; or OFDM sequences are repeatedly mapped within different resource groups; or different OFDM sequences are mapped within the same resource group.

[0257] Step S23: The terminal receives LP-WUS and obtains wake-up information and / or cell index related information.

[0258] Application Scenario 3: Base station and terminal transmission of LP-WUS, using the aforementioned A13

[0259] Specifically, the main implementation process includes:

[0260] Step S31: The base station sends configuration information to at least one terminal to indicate a first signal to the terminal for waking it up;

[0261] It should be noted that the first signal is LP-WUS.

[0262] The configuration information can be found in the detailed descriptions of Application Case 1 and Application Case 2, and will not be repeated here.

[0263] Step S32: The terminal determines the resource mapping relationship between the first sequence and the second sequence carried by LP-WUS;

[0264] An MO carries an L-bit OOK sequence and K1×K2 OFDM sequences, which are then matched to generate a time-domain sequence and / or frequency-domain sequence of a first signal. The matching rules include: the first sequence of length L2 bits and at least one second sequence of length L1 bits are expanded into a joint sequence of length L2×L1 bits by a predefined rule, where L1 and L2 are integers greater than or equal to 1; the predefined rules include: each bit in the first sequence is expanded into a sequence of length L1 bits, the positions with a bit value of 0 are expanded into a sequence of all 0 bits of length L1 bits, and the positions with a bit value of 1 are expanded into the second sequence of length L1 bits.

[0265] The first sequence includes K1×K2 bit positions with a value of 1 or OOK symbols indicating enabled bit positions. According to the expansion rules, they are expanded into K1×K2 second sequences. The K1 second sequences transmit different information, and the K2 second sequences transmit the same information.

[0266] The first sequence includes K1×K3+K4 bit positions (or resource positions) with a bit value of 1 or OOK symbol indicating an open bit position. According to the expansion rules, they are expanded into K1×K3+K4 second sequences. K1 second sequences transmit different information, K3 is the number of times at least one of the K1-K4 second sequences is repeatedly transmitted, and K4 second sequences are repeatedly transmitted K3+1 times.

[0267] The first sequence includes K1+K5 bit positions with a value of 1 or OOK symbols indicating enabled bit positions. According to the expansion rules, each of the K1 second sequences is expanded into K1+K5 second sequences. The K1 second sequences transmit different information, and K5 is the number of times at least one of the K1 second sequences is repeatedly transmitted or the number of times the second sequence is repeatedly transmitted among the K1 second sequences.

[0268] The expansion rules include one of the following:

[0269] The first bit position corresponding to the first sequence with a value of 1 is first expanded into K1 second sequences, and the remaining bit positions corresponding to the first sequence with a value of 1 are repeated K2-1 times.

[0270] The position of the Hth bit of the first sequence that is 1 is repeatedly extended to the ath second sequence, where H takes the value from K2×a to K2×(a+1)-1 and a takes the value from 0 to K1-1; or, H takes the value from K2×(a-1) to K2×a-1 and a takes the value from 1 to K1.

[0271] Based on the above rules, a joint sequence of length L×L1 bits is obtained. Since the rule of applying the frequency domain first and then the time domain is applied to the resources of LP-WUS, the rule can be:
