Description

Technical Field

[0001] This application relates to the field of communication network technology, and in particular to signal transmission methods, signal reception methods, communication devices, and storage media. Background Technology

[0002] For 5G systems, in addition to latency, reliability, and availability, the energy efficiency of terminal equipment (UE) is also crucial. Currently, 5G devices may require charging weekly or daily depending on individual usage. Typically, 5G devices consume tens of milliwatts of power in radio resource control (RRC) idle / inactive states and hundreds of milliwatts in RRC connected states. Therefore, extending battery life is essential for improving energy efficiency and enhancing user experience.

[0003] Since power consumption depends on the configured wake-up cycle length, such as the paging cycle, a low-power wake-up (LP-WUS) mechanism is introduced to meet battery life requirements. This mechanism involves the user using a separate receiver to receive the LP-WUS signal, which is then used to wake up the main radio for data transmission and reception. When the UE does not detect the LP-WUS signal, the main receiver remains in deep sleep, further reducing terminal power consumption.

[0004] However, the use of an ultra-low power wake-up LP-WUS mechanism affects the detection performance of the LP-WUS signal. Furthermore, frequency shift further significantly impacts LP-WUS signal detection. Therefore, improving LP-WUS signal detection performance while minimizing the impact of frequency shift on detection performance during LP-WUS signal reception is a pressing issue.

[0036] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0038] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0039] In the description of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more.

[0040] As in the background technology, in order to meet the requirements of battery life, an ultra-low power wake-up LP-WUS mechanism is introduced. That is, the user uses a separate receiver to receive the LP-WUS signal and wakes up the main radio device to perform data transmission and data reception. When the UE does not detect the LP-WUS signal, the main receiver is in a deep sleep state, thereby further reducing the power consumption of the terminal.

[0041] However, the use of an ultra-low power wake-up LP-WUS mechanism affects the detection performance of the LP-WUS signal. Furthermore, frequency shift further significantly impacts LP-WUS signal detection. Therefore, improving LP-WUS signal detection performance while minimizing the impact of frequency shift on detection performance during LP-WUS signal reception is a pressing issue.

[0042] To address the aforementioned technical problems, embodiments of this application provide a signal transmission method and a signal reception method. The approach involves: a signal transmitting end transmitting a first signal, which carries first data information; wherein the first signal may occupy at least one time-domain symbol; correspondingly, a signal receiving end receiving the first signal and acquiring the first data information carried in the first signal. It is understood that by carrying the first data information in the first signal, the first data information can be embodied in at least one time-domain symbol. In this way, when receiving a detection signal, the signal receiving end can reduce the impact of frequency domain offset on detection performance, thereby improving signal detection performance.

[0043] The technical solutions provided in this application can be applied to various mobile communication networks, such as 5G New Radio (NR) mobile communication networks, future mobile communication networks, or multiple communication convergence systems, etc. This application does not limit them.

[0044] The network architecture of the mobile communication network (including but not limited to 3G, 4G, 5G, and future mobile communication networks) in this application embodiment may include at least a first communication node and a second communication node. It should be understood that, in this example, in the downlink, the first communication node may be a network-side device (e.g., including but not limited to a base station), and the second communication node may be a terminal-side device (e.g., including but not limited to a terminal). Of course, in the uplink, the first communication node may also be a terminal-side device, and the second communication node may also be a network-side device. In device-to-device communication between the two communication nodes, both the first and second communication nodes can be a base station or a terminal. The first and second communication nodes may be referred to as the first node and the second node, respectively.

[0045] For example, taking the first communication node as the base station and the second communication node as the terminal, Figure 1 This diagram illustrates a network architecture of a mobile communication network according to an embodiment of this application. Figure 1 As shown, the mobile communication network includes base station 110 and terminal 120.

[0046] In some embodiments, base station 110 is used to provide wireless access services to multiple terminals. Specifically, a base station provides a service coverage area (also known as a cell). Terminals entering this area can communicate with the base station via wireless signals to receive the wireless access services provided by the base station.

[0047] In some embodiments, base station 110 may be a base station in Long Term Evolution (LTE), Long Term Evolution Advanced (LTEA), or an evolved Node B (eNB or eNodeB), a base station device in a 5G network, or a base station in a future communication system, etc. The base station may include various network-side devices such as macro base stations, micro base stations, home base stations, wireless remote extensions, reconfigurable intelligent surfaces (RIS), routers, wireless fidelity (WIFI) devices, etc.

[0048] In some embodiments, terminal 120 can be a device with wireless transceiver capabilities, which can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on water (such as on ships); and it can also be deployed in the air (e.g., on airplanes, balloons, and satellites). The terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc. The embodiments of this application do not limit the application scenarios. The terminal may also be referred to as user, UE, access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication device, UE agent, or UE device, etc., and the embodiments of this application are not limited to these terms.

[0049] It should be noted that, Figure 1 This is just an example framework diagram. Figure 1 The number of devices included and the names of each device are unlimited, except for... Figure 1 In addition to the devices shown, the communication system may also include other devices, such as core network equipment.

[0050] The application scenarios of the embodiments in this application are not limited. The system architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided by the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this application are also applicable to similar technical problems.

[0051] Figure 2 This is a flowchart illustrating the data processing flow between the sending and receiving ends. (Example) Figure 2 As shown, the transmitting end processes the source (i.e., the data to be transmitted) through source coding, channel coding, modulation, and resource mapping, and then sends the resulting signal to the receiving end. Upon receiving this signal, the receiving end performs resource demapping, demodulation, channel decoding, and source decoding to obtain the destination (i.e., the reconstructed source).

[0052] The signal transmission method and signal reception method provided in the embodiments of this application will be described in detail below. For example, the signal transmission method and signal reception method provided in the embodiments of this application can be applied to, for example... Figure 1 The mobile communication network shown.

[0053] like Figure 3 As shown, the signal transmission method and signal reception method provided in this application embodiment may include the following steps:

[0054] S101, The first communication node sends a first signal. Correspondingly, the second communication node receives the first signal.

[0055] For example, the first signal mentioned above can be an LP WUS signal. It is understood that using the ultra-low power wake-up mechanism LP WUS signal can reduce energy consumption.

[0056] The first signal occupies at least one time-domain symbol in the time domain.

[0057] For example, the time-domain symbols described above may include any one of the following: on-off keying (OOK) symbols, multi-carrier OOK (MC-OOK) symbols, frequency-shift keying (FSK) symbols, multi-carrier FSK (MC-FSK) symbols, and orthogonal frequency division multiplexing (OFDM) symbols. In some embodiments, the time-domain symbols described above are preferably OFDM symbols.

[0058] In some embodiments, the first signal carries first data information.

[0059] For example, the first data information may include at least one of the following: source information, cyclic redundancy check (CRC) bits, and padding bits.

[0060] The padding bits are used to fill in missing bits when the amount of the first data information is less than the default or configured amount. For example, suppose the first data information... The quantity is bits, the default number is L B ,like Then the first data information It also includes The padding bits. These padding bits can be filled with some default values.

[0061] In some embodiments, the first signal carrying first data information includes: the first signal carrying at least one second data information generated from the first data information.

[0062] The aforementioned second data information includes at least one second sub-data information; each second sub-data information is transmitted within at least one time-domain symbol.

[0063] For example, the time-frequency resources corresponding to each second sub-data information occupy the same frequency domain resource location; or, the frequency domain resources occupied by the time-frequency resources corresponding to each second sub-data information are independently configured; or, the frequency domain resource location occupied by the time-frequency resources corresponding to each second sub-data information is indicated by information. For example, the base station can indicate the specific frequency domain resource location by information; or, determine the specific frequency domain resource location according to the default configuration; or, determine the specific frequency domain resource location according to the frequency hopping rule and in combination with the information sent by the base station.

[0064] In some embodiments, the aforementioned second data information is generated in the following manner:

[0065] Method 1: Generate the second data information through the following steps a1-a3.

[0066] Step a1: Perform a first operation on the first data information to obtain the third data information.

[0067] For example, suppose the first data information can be represented as: Then, performing the first operation on the first data information yields the third data information as follows: The length of the third data information is L. C Bit.

[0068] For example, the first operation described above may include at least one of the following: bit-level repetition, encoding, modulation, interleaving, adding padding bits, and adding CRC bits.

[0069] Here, performing bit-level repetition on the first data information means repeating each bit of the first data information.

[0070] For example, suppose the first data information It can be represented as: Length L B Bits. Then for the first data information Performing bit-level repetition operations includes: repetitive operations on the first data information. b i Repeat R0 times to generate data of length R0. It can be represented as: Where 0≤i≤L B -1.

[0071] For example, the above encoding may include at least one of the following: Manchester encoding, Miller encoding, Pulse interval encoding (PIE), bi-phase space coding (also known as FM0 encoding), Reed-Muller (RM) encoding, and Polar encoding, etc.

[0072] Interleaving is used to separate consecutive bits in a message and send them in a non-sequential manner.

[0073] Adding padding bits refers to adding padding bits to the first data information.

[0074] Adding CRC bits refers to adding CRC bits to the first data information. For example, adding CRC bits can be implemented in the following ways:

[0075] When the source information is 2 bits, the CRC selects from [2, 4, 6, 8] bits.

[0076] When the source information is 4 bits, the CRC selects from [4, 6, 8, 10] bits.

[0077] When the source information is 6 bits, the CRC selects from [4, 6, 8, 10, 12] bits.

[0078] When the source information is 8 bits, the CRC selects from [4, 6, 8, 10, 12, 14, 16] bits.

[0079] When the source information is 10 bits, the CRC selects from [6, 8, 10, 12, 14, 16] bits.

[0080] When the source information is 12 bits, the CRC selects from [6, 8, 10, 12, 14, 16] bits.

[0081] When the source information is 14 bits, the CRC selects from [6, 8, 10, 12, 14, 16] bits.

[0082] When the source information is 16 bits, the CRC selects from [8, 10, 12, 14, 16, 18, 20, 22, 24] bits.

[0083] When the source information is 18 bits, the CRC selects from [8, 10, 12, 14, 16, 18, 20, 22, 24] bits.

[0084] When the source information is 20 bits, the CRC selects from the [8, 10, 12, 14, 16, 18, 20, 22, 24] bits.

[0085] When the source information is 22 bits, the CRC selects from [8, 10, 12, 14, 16, 18, 20, 22, 24] bits.

[0086] When the source information is 24 bits, the CRC selects from [8, 10, 12, 14, 16, 18, 20, 22, 24] bits.

[0087] When the source information is 36 bits, the CRC selects from [8, 10, 12, 14, 16, 18, 20, 22, 24, 32, 36, 48] bits.

[0088] When the source information is 48 bits, the CRC selects from [8, 10, 12, 14, 16, 18, 20, 22, 24, 32, 36, 48] bits.

[0089] Step a2: Divide the third data information into at least one third sub-data information.

[0090] The third sub-data information includes multiple data elements read consecutively in the third data information.

[0091] It is understood that a third sub-data information can be considered as a data block, including all or part of the data information in the third data information. For example, when the third data information is divided into multiple third sub-data information, the content of each third sub-data information is different, and the collection of multiple third sub-data information constitutes the complete third data information; when the third data information is divided into a single third sub-data information, that third sub-data information includes all the data information of the third data information.

[0092] For example, the third sub-data information with index i in at least one third sub-data information can be represented as follows: Length is Bits. Where i is an integer, and 0≤i≤I-1, where I is an integer greater than or equal to 1. It can be seen that when the value of i is 0, the number of third sub-data information is 1, that is, the third sub-data information is the third data information.

[0093] In some embodiments, the third sub-data information can be carried as a sequence. For example, suppose the third sub-data information... If the length is 4, then it can be passed through 4. 2 =16 sequences to carry different values ​​of the third sub-data information.

[0094] Step a3: For each third sub-data information, repeat the third sub-data information R1 times to obtain the second data information, where R1 is a positive integer.

[0095] It is understandable that the third sub-data information is repeated once, that is, the third sub-data information is sent once in the first signal.

[0096] In Method 1, the third sub-data information is the aforementioned second sub-data information. That is, a third sub-data information can be transmitted within at least one time-domain symbol.

[0097] For example, the second data information formed by repeating the third sub-data information R1 times can be: in, It can be represented as: in, The length is in, It can be transmitted in R1 time-domain symbols. The frequency domain resources occupied by the R1 time-domain symbols are in the same position; or, The frequency domain resources occupied in the R1 time-domain symbols are configured independently, or, The location of the frequency domain resources occupied in R1 time domain symbols can be indicated by information.

[0098] Method 2: Generate the second data information through the following steps b1-b2.

[0099] Step b1: Perform the first operation on the first data information to obtain the third data information.

[0100] For example, the specific implementation of step b1 above can be found in step a1 above, and will not be repeated here.

[0101] Step b2: Repeat the third data information R1 times to obtain the second data information, where R1 is a positive integer.

[0102] In Method 2, the third data information is the aforementioned second sub-data information. That is, a third data information can be transmitted within at least one time-domain symbol.

[0103] For example, the second data information formed by repeating the third data information R1 times can be: in, can be represented as: in, The length is in, It can be transmitted in R1 time-domain symbols. The frequency domain resources occupied by the R1 time-domain symbols are in the same position; or, The frequency domain resources occupied in the R1 time-domain symbols are configured independently, or, The location of the frequency domain resources occupied in R1 time domain symbols can be indicated by information.

[0104] Method 3: Generate the second data information through the following steps c1-c2.

[0105] Step c1: Divide the first data information into at least one first sub-data information.

[0106] The first sub-data information includes multiple consecutive data elements in the first data information.

[0107] It is understood that a first sub-data information can be considered as a data block, including all or part of the data information in the first data information. For example, when the first data information is divided into multiple first sub-data information, the content of each first sub-data information is different, and the collection of multiple first sub-data information constitutes the complete first data information; when the first data information is divided into a single first sub-data information, that first sub-data information includes all the data information of the first data information.

[0108] For example, the first sub-data information with index i in at least one first sub-data information can be represented as follows: Length is Where i is an integer, and 0≤i≤I-1, I is an integer greater than or equal to 1. It can be seen that when the value of i is 0, the number of the first sub-data information is 1, that is, the first sub-data information is the first data information.

[0109] In some embodiments, the first sub-data information can be carried as a sequence. For example, suppose the first sub-data information... If the length is 4, then it can be passed through 4. 2 =16 sequences to carry different values ​​of the first sub-data information.

[0110] Step c2: For each first sub-data information, repeat the first sub-data information R1 times to obtain the second data information, where R1 is a positive integer.

[0111] In Method 3, the aforementioned first sub-data information is the same as the aforementioned second sub-data information. That is, a first sub-data information can be transmitted within at least one time-domain symbol.

[0112] For example, the second data information formed by repeating the first sub-data information R1 times can be... in, can be represented as: in, The length is in, It can be transmitted in R1 time-domain symbols. The frequency domain resources occupied by the R1 time-domain symbols are in the same position; or, The frequency domain resources occupied in the R1 time-domain symbols are configured independently; or, The location of the frequency domain resources occupied in R1 time domain symbols is indicated by information.

[0113] For example, such as Figure 4 As shown, assuming R1 is 4, the second data information can be represented as follows: Then the second data information It can be transmitted across four time-domain symbols (e.g., OFDM symbols), occupying resources 0, 1, 2, and 3 respectively. Specifically, resource 0 is in OFDM symbol 0, resource 1 in OFDM symbol 1, resource 2 in OFDM symbol 2, and resource 3 in OFDM symbol 3. If the first communication node does not support frequency hopping, the four resources can occupy the same positions in the four OFDM symbols. If the first communication node supports frequency hopping, the positions of the four resources in the four OFDM symbols can be determined by the frequency hopping rules.

[0114] Method 4: Generate the second data information through the following steps d1-d2.

[0115] Step d1: Perform the first operation on each bit in the first data information to obtain the fourth data information.

[0116] Suppose the first data information can be represented as: Performing the first operation on each bit of the first data information means, for the first data information b i Perform the first operation to obtain the fourth data information. Fourth data information It can be represented as Fourth data information The length is bits; where 0 ≤ i ≤ L B -1.

[0117] For example, the first operation described above may include at least one of the following: bit-level repetition, encoding, modulation, interleaving, adding padding bits, and adding CRC bits.

[0118] For example, when the above encoding includes Manchester encoding and the code rate is 1 / 4, when the first data information b i When b = 0,i Data information generated by Manchester encoding [1 0 10]. When the first data information b i When b = 1, i Data information generated through Manchester encoding [0 1 0 1].

[0119] Step d2: Repeat the fourth data information R1 times to obtain the second data information, where R1 is a positive integer.

[0120] In Method 4, the aforementioned fourth data information is the aforementioned second sub-data information. That is, a fourth data information can be transmitted within at least one time-domain symbol.

[0121] It should be noted that the execution order of steps d1 and d2 is not limited in the embodiments of this application. For example, method four can also be implemented as follows: for each bit in the first data information, repeat the bit R1 times; then perform the first operation on each repeated bit to obtain the fourth data information.

[0122] For example, the second data information obtained by repeating the fourth data information R1 times can be: in, It can be represented as: in,

[0123] For example, assuming R1 is 4, then the second data information It can be represented as Then the second data information It can be transmitted over four time-domain symbols (e.g., OFDM symbols), occupying resources 0, 1, 2, and 3 respectively. Specifically, resource 0 is in OFDM symbol 0, resource 1 is in OFDM symbol 1, resource 2 is in OFDM symbol 2, and resource 3 is in OFDM symbol 3.

[0124] like Figure 5 As shown, if the first communication node does not support frequency hopping, the four resources can occupy the same position of the frequency domain resources in the four OFDM symbols.

[0125] like Figure 6 As shown, if the first communication node supports frequency hopping, the position of the frequency domain resources occupied by the four resources in the four OFDM symbols can be configured independently, or a frequency domain frequency hopping pattern can be adopted.

[0126] In some embodiments, one data element in the second data information corresponds to a sequence. For example, the sequence may be a scrambling sequence, a PN sequence, or a ZC sequence.

[0127] In some embodiments, each data element in the second data information corresponds to the same sequence. For example, the sequence can be a scrambling sequence, a PN sequence, or a ZC sequence.

[0128] In some embodiments, the data elements with a value of 1 in the second data information correspond to the same sequence. For example, the above sequence can be a scrambling sequence, a PN sequence, or a ZC sequence.

[0129] In some embodiments, the data elements at the same position in the fourth data information of the repeated R1 in the second data information correspond to the same sequence. For example, the above sequence can be a scrambling sequence, a PN sequence, or a ZC sequence.

[0130] For example, when using Manchester encoding with a code rate of 1 / 4, if the first data information b i When b = 0, i Data information generated by Manchester encoding [1 0 1 0]. When the first data information b i When b = 1, i Data information generated through Manchester encoding [0 1 01]. In this embodiment of the application, the first data information is used. b i =1, the fourth data information generated by encoding Let's take [0 1 0 1] as an example for explanation.

[0131] Assuming the fourth data information When the number of repetitions R1 is 4, the second data information is formed. The expression is:

[0132]

[0133] In this embodiment, the second data information It can be transmitted within MC-OOK based LP-WUS symbols. Each LP-WUS symbol carries the second data information. If one of the data elements is a LP-WUS symbol, then a total of 16 LP-WUS symbols are needed to carry the second data information.

[0134] For example, the time-domain resources corresponding to 4 MC-OOK based LP-WUS symbols can be contained in one OFDM symbol, then 16 MC-OOK based LP-WUS symbols correspond to 4 OFDM symbols. For example, The first (0 1 0 1) bearer is transmitted in OFDM symbol 0 and occupies resource 0; the second (0 1 0 1) bearer is transmitted in OFDM symbol 1 and occupies resource 1; the third (0 1 0 1) bearer is transmitted in OFDM symbol 2 and occupies resource 2; the fourth (0 1 0 1) bearer is transmitted in OFDM symbol 3 and occupies resource 3. Resources 0, 1, 2, and 3 occupy the same frequency domain resources.

[0135] For example, the second data information The sequence of data elements configured in same.

[0136] For example, the second data information The sequence configured for data elements with '1' in the middle. same.

[0137] For example, the second data information The fourth data information in R1 In, the sequence of data elements configured at the same position. Same. For example, The sequence corresponding to the first data element 0 in the first (0 1 0 1) is the same as the sequence corresponding to the first data element 0 in the second (0 1 0 1).

[0138] For example, the second data information The fourth data information in R1 In the configuration sequence, data elements at the same position and whose data element is '1' are considered. Same. For example, The sequence corresponding to the second data element 1 in the first (0 1 0 1) is the same as the sequence corresponding to the second data element 1 in the second (0 1 0 1).

[0139] In some embodiments, the time-domain expression of the MC-OOK based LP-WUS symbol can be generated according to steps e1-e6.

[0140] Step e1: Assume an OFDM symbol includes M MC-OOK based LP-WUS symbols, and assume the data information transmitted on the M OOK symbols is S. M Then define S M=[s0,s1,s2,s3,…,s M-1 The length is M bits, where M is an integer greater than or equal to 1.

[0141] For example, in the above embodiments, S M =[s0,s1,s2,s3,…,s M-1 ] = [0 1 0 1]. Where M = 4.

[0142] Step e2: Transfer data information S M Convert to data information Q K Among them, Q K The length is K bits, where K is greater than or equal to M.

[0143] As one possible implementation, the data information S can be processed according to the following formula (1). M Convert to data information Q K .

[0144]

[0145] Where M*A=K.

[0146] Among them, sequence It can be configured according to actual needs, 0≤i≤M-1.

[0147] Where K is the number of OFDM subcarriers configured in the frequency domain for MC-OOK based LP-WUS symbols.

[0148] As another possible implementation, the data information S can be processed according to the following formula (2). M Convert to data information Q K .

[0149]

[0150] Where A0+A1+…+A i +…+A M-1 =K.

[0151] Among them, sequence It can be configured according to actual needs, 0≤i≤M-1.

[0152] Where K is the number of OFDM subcarriers configured in the frequency domain for MC-OOK based LP-WUS symbols.

[0153] It is understandable that the above formulas (1) and (2) are only for generating data information Q. K The two example methods are illustrated below. In other embodiments, other methods may also be used to generate the data information Q.K This application does not limit the scope of the embodiments.

[0154] Step e3, as Figure 7 As shown, the data information Q K After K-point Discrete Fourier Transform (DFT) or Fast Fourier Transform (FFT), the data information D is obtained. K = [d0,d1,d2,d3,…,d K-1 ].

[0155] Step e4, as Figure 7 As shown, the data information D K The data is filled into the K OFDM subcarriers corresponding to LP-WUS in the frequency domain.

[0156] Step e5, as follows Figure 7 As shown, for the padding data on N subcarriers, an N-point inverse discrete fourier transform (IDFT) or inverse fast fourier transform (IFFT) operation is performed to obtain time-domain data T with N sampling points. N = [t0,t1,t2,t3,…,t N-1 ].

[0157] It is understandable that, since the system's frequency domain bandwidth includes K OFDM subcarriers occupied by LP-WUS, other subcarriers can be filled with other data information. Therefore, when the system's frequency domain bandwidth includes N OFDM subcarriers, the time domain data T of N sampling points can be obtained by executing the above step e5. N .

[0158] Step e6: Determine the time-domain expression of the MC-OOK based LP-WUS symbol.

[0159] In some embodiments, when no other data is being transmitted in the system besides LP-WUS, T is determined. N =[t0,t1,t2,t3,…,t N-1 ] represents the sampling point data of M OOK time-domain symbols.

[0160] For example, such as Figure 8 As shown, where [t0,t1,t2,t3,…,t] N / M-1 ] represents the sampling point data of the first OOK time-domain symbol out of M OOK time-domain symbols, [t N / M,t N / M+1 ,…,t 2N / M-1 ] represents the sampling point data of the second OOK time-domain symbol out of M OOK time-domain symbols, and so on, [t (M-1)N / M ,t (M-1)N / M+1 ,…,t N-1 ] represents the sampling point data of the Mth OOK time-domain symbol out of M OOK time-domain symbols.

[0161] In some embodiments, when there is other data transmission in the system besides LP-WUS, T is determined. N =[t0,t1,t2,t3,…,t N-1 ] is the superposition expression of time-domain symbolic sampling point data of LP-WUS and other data.

[0162] Among them, the sampling point data of the first OOK time-domain symbol out of the M OOK time-domain symbols is contained in [t0, t1, t2, t3, ..., t N / M-1 The sampling data of the second OOK time-domain symbol out of M OOK time-domain symbols is contained in [t]. N / M ,t N / M+1 ,…,t 2N / M-1 In [t], and so on, the sampling point data of the Mth OOK time-domain symbol out of M OOK time-domain symbols is included in [t]. (M-1)N / M ,t (M-1)N / M+1 ,…,t N-1 ]middle.

[0163] In some embodiments, the time-domain data T of N sampling points N =[t0,t1,t2,t3,…,t N-1 Before transmission, a cyclic prefix (CP) operation needs to be performed, which involves adding a cyclic prefix to the time-domain data T of N sampling points. N N at the tail cp The time-domain data T, which is copied from the information of one sampling point to N sampling points, is... N The head is removed, forming (N+N) cp The time-domain data of (N+N) sampling points, and then these (N+N) cp The time-domain data of ) sampling points are sent out.

[0164] In some embodiments, the first signal carries at least one second data information, including: the first signal carries at least one fifth data information, each fifth data information being obtained by repeating a second data information R2 times, where R2 is a positive integer.

[0165] For example, in a fifth data information, the time-frequency resources corresponding to each second data information occupy the same frequency domain resource position in the frequency domain; or, the frequency domain resource positions corresponding to each second data information are configured independently; or, the frequency domain resource positions corresponding to each second data information are indicated by information.

[0166] For example, regarding the second data information Repeat R2 times to obtain the fifth data information in,

[0167] It can be represented as: in, The length is

[0168] For example, such as Figure 9 As shown, assuming R1 is 4, the second data information obtained through method one, method two, or method three is... It can be represented as Assuming R² is 2, the fifth data information obtained by repeating the second data information twice can be represented as follows:

[0169] Among them, the fifth data information The first second data information in It is transmitted over four time-domain symbols (e.g., OFDM symbols), occupying resources 0, 1, 2, and 3 respectively (each resource is used to transmit one). In this diagram, resource 0 is in OFDM symbol 0, resource 1 is in OFDM symbol 1, resource 2 is in OFDM symbol 2, and resource 3 is in OFDM symbol 3. The four resources can occupy the same frequency domain resources in the four OFDM symbols.

[0170] Fifth data information The second data information in It is transmitted over four OFDM symbols, occupying resources 4, 5, 6, and 7 respectively (each resource is used to transmit one). In this context, resource 4 is in OFDM symbol 4, resource 5 is in OFDM symbol 5, resource 6 is in OFDM symbol 6, and resource 7 is in OFDM symbol 7. The four resources can occupy the same frequency domain position in the four OFDM symbols, but their positions must correspond to the fifth data information. The first second data information in The frequency domain locations they occupy in the frequency domain resources are different.

[0171] For example, such as Figure 10As shown, assuming R1 is 4, the second data information obtained through method four above... It can be represented as

[0172] Assuming R² is 2, the fifth data information obtained by repeating the second data information twice can be represented as follows:

[0173] Among them, the fifth data information The first second data information in It is transmitted over four time-domain symbols (e.g., OFDM symbols), occupying resources 0, 1, 2, and 3 respectively (each resource is used to transmit one). In this diagram, resource 0 is in OFDM symbol 0, resource 1 is in OFDM symbol 1, resource 2 is in OFDM symbol 2, and resource 3 is in OFDM symbol 3. The four resources can occupy the same frequency domain resources in the four OFDM symbols.

[0174] Fifth data information The second data information in It is transmitted over four OFDM symbols, occupying resources 4, 5, 6, and 7 respectively (each resource is used to transmit one). In this context, resource 4 is in OFDM symbol 4, resource 5 is in OFDM symbol 5, resource 6 is in OFDM symbol 6, and resource 7 is in OFDM symbol 7. The four resources can occupy the same frequency domain position in the four OFDM symbols, but their positions must correspond to the fifth data information. The first second data information in The locations of the frequency domain resources are different.

[0175] In some embodiments, the first signal carries at least one second data information, including: the first signal carries sixth data information, the sixth data information is obtained by repeating the seventh data information R3 times, and the seventh data information is composed of at least one second data information; or, the seventh data information is composed of at least one fifth data information, where R3 is a positive integer.

[0176] For example, in a sixth data information, the time-frequency resources corresponding to each seventh data information occupy the same frequency domain resource position in the frequency domain; or, the frequency domain resource positions corresponding to each seventh data information are configured independently; or, the frequency domain resource positions corresponding to each seventh data information are indicated by information.

[0177] For example, at least one second data information The seventh data information formed by the merger It can be represented as: Among them, the seventh data information The length is: Bit.

[0178] For example, at least one fifth data information The merger constitutes the seventh data information It can be represented as: Among them, the seventh data information The length is Bit.

[0179] For example, the seventh data information The sixth data information obtained by repeating R3 times It can be represented as:

[0180] For ease of understanding, the data rights management information provided in the embodiments of this application will be described below using different scenarios as examples.

[0181] It is understood that in the signal transmission and signal reception methods provided in this application embodiment, the signal transmitting end transmits a first signal and carries first data information in the first signal; wherein, the first signal may occupy at least one time domain symbol (e.g., an OFDM symbol); wherein, in this application embodiment, the first data information may undergo first operations, block division, repetition, etc., to reduce the impact of frequency domain offset on detection performance, and the first data information may be transmitted on at least one time domain symbol, and different methods may be used to configure the frequency domain resources occupied by the first data information. Thus, when the signal receiving end receives the detection signal, it can effectively reduce the impact of frequency domain offset on detection performance.

[0182] Scenario 1: The first signal carries the fifth data information. First, the second data information is generated based on the method described in step three above. Then, the second data information is repeated R2 times to obtain the fifth data information.

[0183] The following embodiments use the LP-WUS signal as the first signal for illustration.

[0184] For example, in scenario one, the signal transmission method provided in this application embodiment can be implemented as follows:

[0185] Step f1: Construct the first data information.

[0186] Wherein, the length L of the first data information B The first data information is 8 bits. It can be represented as: B LB =[b0,b1,b2,b3,b4,b5,b6,b7].

[0187] Step f2: Transfer the first data information It is divided into two data blocks, each block containing the first data information. The data consists of 4 bits.

[0188] It is understandable that the aforementioned Block is the first sub-data information in Method 3.

[0189] For example, suppose the data information included in the Block with index i can be represented as follows: Length is Bits. Therefore, in this embodiment, the first block can be represented as... The second block can be represented as

[0190] In some embodiments, data information in a block Transmitted in an OFDM symbol.

[0191] In some embodiments, the sequence can be used to carry out the data. For example, in this embodiment of the application, the length of the data information in each block is 4 bits, which can be achieved through 4 2 = 16 sequences to carry Different values ​​of .

[0192] Step f3: Data information in each block Data information Repeat R1 times to obtain the second data information. R1 is a positive integer.

[0193] For example, if R1 = 4, then the above second data information It can be represented as in, include: and

[0194] Step f4: Transfer the second data information Repeat R2 times to obtain the fifth data information.

[0195] For example, if R2 = 2, then the fifth data information It can be represented as in, include: and

[0196] Step f5: Transmit the fifth data information in the LP-WUS signal.

[0197] For example, such as Figure 11 As shown, The first one in Transmitted across four OFDM symbols, occupying resources 0, 1, 2, and 3 respectively. Specifically, resource 0 is in OFDM symbol 0, resource 1 in OFDM symbol 1, resource 2 in OFDM symbol 2, and resource 3 in OFDM symbol 3. The four resources can occupy the same frequency domain resources in the four OFDM symbols. The second one Transmission occurs across four OFDM symbols, occupying resources 4, 5, 6, and 7 respectively. Specifically, resource 4 is in OFDM symbol 4, resource 5 in OFDM symbol 5, resource 6 in OFDM symbol 6, and resource 7 in OFDM symbol 7. The four resources can occupy the same frequency domain resources across the four OFDM symbols, but... The first one in The frequency domain locations they occupy in the frequency domain resources are different.

[0198] The first one in The signal is transmitted across four OFDM symbols, occupying resources 8, 9, 10, and 11 respectively. Specifically, resource 8 is in OFDM symbol 14, resource 9 in OFDM symbol 15, resource 10 in OFDM symbol 16, and resource 11 in OFDM symbol 17. The four resources can occupy the same frequency domain resources in the four OFDM symbols. The second one Transmitted across four OFDM symbols, occupying resources 12, 13, 14, and 15 respectively. Resource 12 is in OFDM symbol 21, resource 13 in OFDM symbol 22, resource 14 in OFDM symbol 23, and resource 15 in OFDM symbol 24. The four resources can occupy the same frequency domain resources in the four OFDM symbols, but... The first one in The frequency domain locations they occupy in the frequency domain resources are different.

[0199] Scenario 2: The first signal carries the sixth data information. First, second data information is generated based on the method described in step 3 above. Then, at least one of the second data information is used to construct the seventh data information. This seventh data information is repeated R3 times to obtain the sixth data information.

[0200] For example, in scenario two, the signal transmission method provided in this application embodiment can be implemented as follows:

[0201] Step g1: Construct the first data information.

[0202] Wherein, the length L of the first data information B The first data information is 8 bits. It can be represented as:

[0203] Step g2: Transfer the first data information It is divided into two data blocks, each block containing the first data information. The data consists of 4 bits.

[0204] For example, the first block can be represented as The second block can be represented as

[0205] In some embodiments, data information in a block Transmitted in an OFDM symbol.

[0206] In some embodiments, the sequence can be used to carry out the data. For example, in this embodiment of the application, the length of the data information in each block is 4 bits, which can be achieved through 4 2 = 16 sequences to carry Different values ​​of .

[0207] Step g3: Data information in each block Data information Repeat R1 times to obtain the second data information. R1 is a positive integer.

[0208] For example, if R1 = 4, then the above second data information It can be represented as: and

[0209] Step g4: From at least one second data information The combined data constitutes the seventh data information P. LP .

[0210] For example, the above seven data information It can be represented as:

[0211] Step g5: Transfer the seventh data information Repeat R3 times to obtain the sixth data information. Where R3 is a positive integer.

[0212] For example, R3 can be 2, then the sixth data information It can be represented as:

[0213]

[0214] Step g6: Transmit the sixth data information carried in the LP-WUS signal.

[0215] For example, such as Figure 12 As shown, the sixth data information The first one in In Transmission occurs across four OFDM symbols, occupying resources 0, 1, 2, and 3 respectively. Specifically, resource 0 is in OFDM symbol 0, resource 1 in OFDM symbol 1, resource 2 in OFDM symbol 2, and resource 3 in OFDM symbol 3. The positions of the frequency domain resources occupied by these four resources across the four OFDM symbols can be determined by the frequency domain frequency hopping rules. The signal is transmitted across four OFDM symbols, occupying resources 4, 5, 6, and 7 respectively. Specifically, resource 4 is in OFDM symbol 4, resource 5 in OFDM symbol 5, resource 6 in OFDM symbol 6, and resource 7 in OFDM symbol 7. The positions of the frequency domain resources occupied by these four resources across the four OFDM symbols can be determined by the frequency domain frequency hopping rules.

[0216] Sixth Data Information The second one In Transmitted across four OFDM symbols, occupying resources 8, 9, 10, and 11 respectively. Specifically, resource 8 is in OFDM symbol 14, resource 9 in OFDM symbol 15, resource 10 in OFDM symbol 16, and resource 11 in OFDM symbol 17. The location of these four resources within the four OFDM symbols can be determined by frequency hopping rules. The second... In The signal is transmitted across four OFDM symbols, occupying resources 12, 13, 14, and 15 respectively. Specifically, resource 12 is in OFDM symbol 21, resource 13 in OFDM symbol 22, resource 14 in OFDM symbol 23, and resource 15 in OFDM symbol 24. The positions of the frequency domain resources occupied by these four resources across the four OFDM symbols can be determined by the frequency domain frequency hopping rules.

[0217] In some embodiments, for the first In And the second middle The same frequency hopping rules can be used; or, each frequency hopping rule can be configured independently.

[0218] For example, if the first In And the second middle Using the same frequency hopping rule, resources 0 and 8 occupy the same frequency resource positions, resources 1 and 9 occupy the same frequency resource positions, resources 2 and 10 occupy the same frequency resource positions, and resources 3 and 11 occupy the same frequency resource positions.

[0219] For example, if the first In And the second middle Using the same frequency hopping rule, the frequency resource interval between resource 0 and resource 1 is the same as the frequency resource interval between resource 8 and resource 9, the frequency resource interval between resource 1 and resource 2 is the same as the frequency resource interval between resource 9 and resource 10, and the frequency resource interval between resource 2 and resource 3 is the same as the frequency resource interval between resource 10 and resource 11. Furthermore, the frequency resource locations occupied by resource 0 and resource 8 can be the same or different.

[0220] In some embodiments, for the first In And the second middle The same frequency hopping rules can be used; or, each frequency hopping rule can be configured independently.

[0221] For example, if the first In And the second middle Using the same frequency hopping rule, resources 4 and 12 occupy the same frequency resource positions, resources 5 and 13 occupy the same frequency resource positions, resources 6 and 14 occupy the same frequency resource positions, and resources 7 and 15 occupy the same frequency resource positions.

[0222] For example, if the first In And the second middle Using the same frequency hopping rule, the frequency resource interval between resources 4 and 5 is the same as that between resources 12 and 13, the frequency resource interval between resources 5 and 6 is the same as that between resources 13 and 14, and the frequency resource interval between resources 6 and 7 is the same as that between resources 14 and 15. Furthermore, the frequency resource locations occupied by resources 4 and 12 can be the same or different.

[0223] Scenario 3: The first signal carries the sixth data information. First, second data information is generated based on the above-mentioned method 4. Then, at least one of the second data information is used to construct the seventh data information. The seventh data information is repeated R3 times to obtain the sixth data information.

[0224] For example, in scenario three, the signal transmission method provided in this application embodiment can be implemented as follows:

[0225] Step h1: Construct the first data information.

[0226] Wherein, the length L of the first data information B The first data information is 16 bits. It can be represented as: Where b0, b1, b2, b3, b4, b5, b6, b7 are source information bits, while b8, b9, b1, b2, b3, b4, b5, b6, b7 are source information bits. 10 ,b 11 ,b 12 ,b 13 ,b 14 ,b 15 For CRC bits.

[0227] Step h2, for the first data information Each bit b in i Manchester encoding is performed to obtain the fourth data information.

[0228] For example, the Manchester encoding has a code rate of 1 / 4. When the first data information... b i When b = 0, i Data information generated by Manchester encoding [1 0 1 0]. When the first data information b i When b = 1, i Data information generated through Manchester encoding [0 1 0 1].

[0229] For example, the first data information Each bit b in i Fourth data information generated by Manchester encoding It can be represented as Among them, data information And its length is 4 bits.

[0230] Step h3: Transfer data information Repeat R1 times to obtain the second data information, where R1 is a positive integer.

[0231] For example, R1 can be 2, then the second data information It can be represented as

[0232] Step h4: Combine different second data information The merger constitutes the seventh data information

[0233] For example, It can be represented as

[0234] Step h5: Transfer the seventh data information The sixth data information obtained by repeating R3 times

[0235] For example, R3 can be 2, then the sixth data information It can be represented as:

[0236]

[0237] For example, R3 seventh data information The location of the frequency domain resources occupied in an OFDM symbol can be configured.

[0238] Step h6: Transfer the sixth data information It is transmitted in MC-OOK based LP-WUS symbols.

[0239] For example, the resources occupied by M (for example, M=8) MC-OOK based LP-WUS symbols are included in one OFDM symbol. The time-domain expression of the M OOK symbols can be generated by the methods provided in steps e1-e6 above.

[0240] For example, based on the data information sent on the M OOK symbols in step e1 above, S M Define S M =[s0,s1,s2,s3,…,s M-1 ], and its length is M = 8. For example Figure 13 As shown in this embodiment, the data information transmitted on resource 0 in OFDM symbol 0 is: Right now Then, based on steps e1-e6 above, generate time-domain expressions for M = 8 OOKsymbols.

[0241] The data information transmitted on resource 1 in OFDM symbol 1 is: Right now Then, based on steps e1-e6 above, the time-domain expressions for M = 8 OOK symbols are generated.

[0242] Similarly, the data information transmitted on resource 15 in OFDM symbol 24 is... Right now Then, following steps e1-e6 above, the time-domain expressions for the M=8 OOK symbols are generated.

[0243] Similarly, the data information transmitted on resource 16 in OFDM symbol 28 is... Right now Then, following steps e1-e6 above, the time-domain expressions for the M=8 OOK symbols are generated.

[0244] Similarly, the data information transmitted on resource 17 in OFDM symbol 29 is... Right now Then, following steps e1-e6 above, the time-domain expressions for the M=8 OOK symbols are generated.

[0245] Similarly, the data information transmitted on resource 31 in OFDM symbol 52 is... Right now Then, following steps e1-e6 above, the time-domain expressions for the M=8 OOK symbols are generated.
