Description

Processing method, intelligent terminal and storage medium Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a processing method, an intelligent terminal, and a storage medium. Background Art

[0002] In some implementations, the S-SS (Sidelink Synchronization Signal) / PSBCH (Physical Sidelink Broadcast Channel) block is mapped to 11 consecutive physical resource blocks. However, in unlicensed spectrum, regulations stipulate that each transmission must occupy at least 80% of the bandwidth in the frequency domain, namely the OCB (Occupied Channel Bandwidth) requirement. The bandwidth of the carrier in unlicensed spectrum is 20MHz, which corresponds to 106 physical resource blocks at a 15kHz SCS (Sub-Carrier Spacing) and 51 physical resource blocks at a 30kHz SCS. Obviously, continuing to use the mapping method of 11 consecutive physical resource blocks cannot meet regulatory requirements.

[0003] In addition, regulatory regulations limit the transmit power within a 1MHz bandwidth of the spectrum, for example, to 10dB / MHz. Using 11 consecutive physical resource blocks for mapping will reduce the transmit power of the S-SS / PSBCH block, thus affecting coverage.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art.

[0087] It should be noted that, in this document, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0088] It should be understood that although the terms "first," "second," "third," etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are used solely to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the term "if," as used herein, may be interpreted as "upon," "when," or "in response to a determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context indicates otherwise. It should be further understood that the terms "comprising" and "including" indicate the presence of the recited features, steps, operations, elements, components, items, types, and / or groups, but do not preclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, types, and / or groups. The terms "or," "and / or," "including at least one of the following," etc., as used herein, may be interpreted as inclusive, meaning any one or any combination. For example, “comprising at least one of the following: A, B, C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”; and for another example, “A, B or C” or “A, B and / or C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”. An exception to this definition will occur only when a combination of elements, functions, steps or operations are inherently mutually exclusive in some manner.

[0089] It should be understood that, although the various steps in the flowchart in the embodiment of the present application are shown in sequence according to the indication of the arrows, these steps are not necessarily performed in sequence in the order indicated by the arrows. Unless clearly stated herein, the execution of these steps is not strictly limited in order, and they can be performed in other orders. Moreover, at least a portion of the steps in the figure may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and their execution order is not necessarily performed in sequence, but can be performed in turn or alternately with at least a portion of other steps or sub-steps or stages of other steps.

[0090] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to the determination" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)," depending on the context.

[0091] It should be noted that in this article, step codes such as S110 and S120 are used for the purpose of expressing the corresponding content more clearly and concisely, and do not constitute a substantial limitation on the order. Those skilled in the art may execute S120 first and then S110 during specific implementation, but these should all be within the scope of protection of this application.

[0092] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0093] In the subsequent description, the use of suffixes such as "module", "component" or "unit" to represent elements is only for the purpose of facilitating the description of the present application and has no specific meaning.

It will be understood by those skilled in the art that, in addition to components specifically used for mobile purposes, the configuration according to the embodiments of the present application can also be applied to fixed-type terminals.

[0096] Please refer to FIG1 , which is a schematic diagram of the hardware structure of a mobile terminal for implementing various embodiments of the present application. The mobile terminal 100 may include components such as an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (Audio / Video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and / or a power supply 111. Those skilled in the art will appreciate that the mobile terminal structure shown in FIG1 does not limit the mobile terminal. The mobile terminal may include more or fewer components than shown, or may combine certain components, or arrange the components differently.

[0097] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0098] The RF unit 101 can be used to send and receive signals during information transmission or calls. It can also receive downlink information from the base station and pass it to the processor 110 for processing. It can also send uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and more. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication. The above-mentioned wireless communications can use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution) and 5G, etc.

[0099] WiFi is a short-range wireless transmission technology. A mobile terminal, through WiFi module 102, enables users to send and receive emails, browse web pages, and access streaming media, providing wireless broadband Internet access. Although FIG1 illustrates WiFi module 102, it is understood that it is not a required component of the mobile terminal and can be omitted as needed without altering the essence of the invention.

[0100] The audio output unit 103 can convert audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Furthermore, the audio output unit 103 can also provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, or the like.

[0101] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos captured by an image capture device (e.g., a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 106. The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0102] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor and / or other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured in the mobile phone, such as fingerprint sensor, pressure sensor, iris sensor, molecular sensor, gyroscope, barometer, hygrometer, thermometer, infrared sensor, etc., they will not be described in detail here.

Optionally, the user input unit 107 may include a touch panel 1071 and / or other input device 1072. The touch panel 1071, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by the user using a finger, stylus, or any other suitable object or accessory on or near the touch panel 1071) and drive corresponding connected devices according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 110. It can also receive commands sent by the processor 110 and execute them. In addition, the touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and / or surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072. Optionally, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power keys, etc.), a trackball, a mouse, a joystick, etc., and the specifics are not limited here.

[0105] Optionally, the touch panel 1071 may overlay the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. The processor 110 then provides a corresponding visual output on the display panel 1061 based on the type of touch event. Although in FIG1 , the touch panel 1071 and the display panel 1061 are shown as two separate components to implement the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 may be integrated to implement the input and output functions of the mobile terminal, which is not limited to this specific embodiment.

Furthermore, memory 109 may include high-speed random access memory and non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage device.

[0108] Processor 110 is the control center of the mobile terminal, connecting all components of the mobile terminal using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 109 and / or accessing data stored in memory 109, it executes various functions of the mobile terminal and processes data, thereby providing overall monitoring of the mobile terminal. Processor 110 may include one or more processing units; preferably, processor 110 may integrate an application processor and a modem processor. Optionally, the application processor primarily processes the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 110.

[0109] The mobile terminal 100 may also include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 through a power management system, thereby implementing functions such as managing charging, discharging, and / or power consumption management through the power management system.

[0117] Although the above introduction is made using the LTE system as an example, those skilled in the art should know that this application is not only applicable to the LTE system, but can also be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA and / or future new network systems (such as 5G), etc., which are not limited here.

[0118] Based on the above-mentioned mobile terminal hardware structure and / or communication network system, various embodiments of the present application are proposed.

[0119] In some implementations, the sidelink synchronization information block is mapped to 11 consecutive physical resource blocks (PRBs). However, in unlicensed spectrum, regulations require that each transmission occupy at least 80% of the frequency bandwidth, i.e., the channel bandwidth. The carrier bandwidth in unlicensed spectrum is 20 MHz, which corresponds to 106 PRBs for a 15 kHz SCS and 51 PRBs for a 30 kHz SCS. Clearly, continuing to use 11 consecutive PRBs for mapping will not meet regulatory requirements.

[0120] In addition, regulatory regulations limit the transmit power at 1MHz, for example, 10dB / MHz. Using 11 consecutive physical resource blocks will reduce the transmit power of the S-SS / PSBCH block, thus affecting coverage.

[0121] The technical solution provided in this application is intended to solve the above technical problems.

[0122] The main idea of ​​the present application is that the synchronization signal may contain at least one kind of information, for example, the first information is used for automatic gain control estimation, and / or for carrying the physical broadcast channel and / or demodulation reference signal; the second information is used to carry the main synchronization sequence; the third information is used to carry the auxiliary synchronization sequence; the fourth information is used to carry the physical broadcast channel and / or demodulation reference signal. The present application adjusts the distribution position of the physical resource blocks mapped by various information in the frequency domain and / or the sequence length used by the synchronization sequence, so that the bandwidth range occupied by the synchronization signal in frequency meets the regulatory requirements (such as OCB>80%). In addition, the bandwidth increase can also correspondingly increase the transmission power of the synchronization signal, thereby helping to improve the signal coverage effect.

[0123] It can be understood that the processing steps of the processing method in this application can be implemented by a terminal device.

[0137] Optionally, the primary synchronization sequence is continuously mapped from the 3rd subcarrier to the 129th subcarrier of the primary isochronous signal block.

[0138] Optionally, all subcarriers of the primary synchronization block of the symbol where the primary synchronization sequence is located are set to 0 except for the subcarriers occupied by the primary synchronization sequence.

[0155] Optionally, in actual implementation, a combination may be performed according to actual conditions to obtain a synchronization signal, as shown in Table 1 below.

[0156] Table 1

[0157]

[0158] For example, for combination example A1, the synchronization signal may include the first information, the second information, and the third information, but not the fourth information.

[0159] For another example, for combination example A2, the synchronization signal may include the first information, the second information, and the fourth information, but not the third information.

[0160] For example, for combination example A3, the synchronization signal may include the first information, the third information, and the fourth information, but not the second information.

[0161] For another example, for combination example A4, the synchronization signal may include the second information, the third information, and the fourth information, but not the first information.

[0162] For another example, for combination example A5, the synchronization signal may include first information, second information, third information and fourth information.

[0163] Through the combined solution, the first device can determine or generate multiple synchronization signals containing different information contents, so as to better synchronize information with the second device.

[0164] The above examples are only for reference. In order to avoid redundancy, they will not be listed one by one here. In actual development or application, they can be flexibly combined according to actual needs, but any combination belongs to the technical solution of this application and is covered within the scope of protection of this application.

[0165] S120: The first device sends a synchronization signal.

[0166] Optionally, after determining or generating the synchronization signal, the first device sends the synchronization signal to the second device that needs to perform synchronization processing.

[0167] It can be understood that the number of the second devices can be one or more, and this embodiment does not limit this.

[0168] S130. The second device receives a synchronization signal, where the synchronization signal includes at least one of the first information, the second information, the third information, and the fourth information.

[0169] S140: The second device performs processing according to the synchronization signal.

[0170] Optionally, after receiving the synchronization signal sent by the second device, the second device performs information synchronization processing with the first device according to the synchronization signal.

[0171] In this embodiment, the first device determines or generates a synchronization signal and sends it to the second device. After receiving the synchronization signal, the second device performs information synchronization processing according to the synchronization signal. The synchronization signal includes at least one of the first information, the second information, the third information and the fourth information, thereby ensuring information synchronization between terminal devices.

[0172] For ease of understanding, the technical solution of the present application is explained below by taking the case where the synchronization signal includes the first information, the second information, the third information and the fourth information at the same time as an example.

[0173] When the first device and the second device transmit information, various information in the synchronization signal is mapped to the physical resource blocks in the frequency domain. In order to ensure that the bandwidth range occupied by the synchronization signal in frequency meets regulatory requirements (such as OCB>80%), and secondly, to increase the transmission power of the synchronization signal, this embodiment adjusts the distribution position of the physical resource blocks to which various information is mapped in the frequency domain and / or the sequence length used by the synchronization sequence. The following is a specific embodiment:

[0174] Example 1

[0175] The physical resource blocks mapped by the first information are non-continuously distributed in the frequency domain, and the physical resource blocks mapped by the second information, the third information and the fourth information are continuously distributed in the frequency domain.

[0176] Optionally, the physical resource blocks mapped by the first information are non-continuously distributed in the frequency domain, and specifically can be mapped to the physical resource blocks in an equally spaced manner. The equally spaced physical resource blocks can be understood as a comb structure in the frequency domain. The comb structure is called interleaving, and the entire carrier bandwidth or resource pool is divided into several interleavings. Optionally, the number of interleavings is negatively correlated with the subcarrier spacing. For example, when the subcarrier spacing is 15kHz, it is divided into 10 interleavings, and when the subcarrier spacing is 30kHz, it is divided into 5 interleavings. Therefore, for a subcarrier spacing of 15 / 30kHz, each 10th / 5th resource block belongs to the same interleaving.

[0177] Optionally, the spacing distance between physical resource blocks is negatively correlated with the subcarrier spacing.

[0178] For example, if the subcarrier spacing is 15 kHz, the spacing between physical resource blocks is 10, and if the subcarrier spacing is 30 kHz, the spacing between physical resource blocks is 5. Here, a resource block to which information is mapped and subsequent unmapped consecutive resource blocks can be regarded as an "interlace".

[0179] Optionally, the first information may occupy at least one interlace.

[0180] Optionally, the first information may occupy 10, 11 or other numbers of physical resource blocks.

[0181] For example, Figure 4 is a schematic diagram of the synchronization signal provided in an embodiment of the present application. As shown in Figure 4, the synchronization signal occupies 13 symbols in the time domain, that is, it is located in the first 13 symbols of a time slot. It can be understood that the last symbol of a time slot carrying the synchronization signal serves as a protection interval.

[0182] Optionally, with reference to Figure 4, in the synchronization signal, the first symbol is used to represent the first information, that is, used as AGC, and / or used to carry the physical broadcast channel and / or the demodulation reference signal, the second and third symbols are used to represent the second information, that is, used to carry the primary synchronization sequence S-PSS, the fourth and fifth symbols are used to represent the third information, that is, used to carry the secondary synchronization sequence S-SSS, and the sixth to thirteenth symbols are used to represent the fourth information, that is, used to carry the physical broadcast channel and / or the demodulation reference signal. Optionally, the primary synchronization sequence carried on the second and third symbols is the same, and the secondary synchronization sequence carried on the fourth and fifth symbols is the same.

[0183] Optionally, referring to FIG4 , the first information may be mapped to physical resource blocks at equal intervals in the frequency domain, and the second information, the third information and the fourth information may be mapped to at least one continuous physical resource block in the frequency domain.

[0184] Optionally, the starting distribution position of at least one consecutive physical resource block mapped in the frequency domain by the second information, the third information and the fourth information is the same in the frequency domain, and the starting distribution position is the same as the distribution position of any physical resource block mapped by the first information.

[0185] For example, the starting distribution position of at least one continuous physical resource block mapped in the frequency domain by the second information, the third information and the fourth information in FIG4 is the same as the distribution position of the fifth physical resource block mapped by the first information.

[0186] Optionally, the starting position of each physical resource block is configured and / or pre-configured by higher layer signaling.

[0187] Optionally, the starting position of each interlace is configured and / or pre-configured by higher layer signaling.

[0188] This example adjusts the distribution position of the physical resource blocks mapped by the first information in the frequency domain so that the bandwidth range occupied by the synchronization signal in frequency meets regulatory requirements (such as OCB>80%). In addition, the increase in bandwidth can also correspondingly increase the transmission power of the synchronization signal, thereby helping to improve the signal coverage effect.

[0189] Example 2

[0190] The physical resource blocks mapped by the fourth information are non-continuously distributed in the frequency domain, and the physical resource blocks mapped by the first information, the second information and the third information are continuously distributed in the frequency domain.

[0191] Optionally, the physical resource blocks mapped by the fourth information are non-continuously distributed in the frequency domain, and specifically can be mapped to the physical resource blocks in an equally spaced manner. The equally spaced physical resource blocks can be understood as a comb structure in the frequency domain. The comb structure is called interleaving, and the entire carrier bandwidth or resource pool is divided into several interleavings. Optionally, the number of interleavings is negatively correlated with the subcarrier spacing. For example, when the subcarrier spacing is 15kHz, it is divided into 10 interleavings, and when the subcarrier spacing is 30kHz, it is divided into 5 interleavings. Therefore, for a subcarrier spacing of 15 / 30kHz, each 10th / 5th resource block belongs to the same interleaving.

[0192] Optionally, the spacing distance between physical resource blocks is negatively correlated with the subcarrier spacing.

[0193] For example, Figure 5 is another schematic diagram of the synchronization signal provided in an embodiment of the present application. As shown in Figure 5, in the synchronization signal, the fourth information can be mapped to the physical resource block in an equally spaced manner in the frequency domain, and the second information, the third information and the first information are mapped to at least one continuous physical resource block in the frequency domain.

[0194] Optionally, the starting distribution positions of at least one consecutive physical resource block mapped by the second information, the third information and the first information in the frequency domain are the same, and the starting distribution position is the same as the distribution position of any physical resource block mapped by the fourth information.

[0195] For example, the starting distribution position of at least one continuous physical resource block mapped in the frequency domain by the second information, the third information and the first information in FIG5 is the same as the distribution position of the fifth physical resource block mapped by the fourth information.

[0196] Optionally, the starting position of each physical resource block is configured and / or pre-configured by higher layer signaling.

[0197] Optionally, the starting position of each interlace is configured and / or pre-configured by higher layer signaling.

[0198] This example adjusts the distribution position of the physical resource blocks mapped by the fourth information in the frequency domain so that the bandwidth range occupied by the synchronization signal in frequency meets regulatory requirements (such as OCB>80%). In addition, the increase in bandwidth can also correspondingly increase the transmission power of the synchronization signal, thereby helping to improve the signal coverage effect.

[0199] Example 3

[0200] The physical resource blocks mapped by the first information and the physical resource blocks mapped by the fourth information are non-continuously distributed in the frequency domain; the physical resource blocks mapped by the second information and the third information are continuously distributed in the frequency domain.

[0201] Optionally, the physical resource blocks mapped by the first information and the physical resource blocks mapped by the fourth information are non-continuously distributed in the frequency domain, and specifically may be mapped to the physical resource blocks in an equally spaced manner. The equally spaced physical resource blocks may be understood as a comb structure in the frequency domain. The comb structure is called an interlace, and the entire carrier bandwidth or resource pool is divided into several interlaces. Optionally, the number of interlaces is negatively correlated with the subcarrier spacing, for example, when the subcarrier spacing is 15kHz, it is divided into 10 interlaces, and when the subcarrier spacing is 30kHz, it is divided into 5 interlaces. Therefore, for a subcarrier spacing of 15 / 30kHz, each 10th / 5th resource block belongs to the same interlace.

[0202] Optionally, the spacing distance between physical resource blocks is negatively correlated with the subcarrier spacing.

[0203] For example, Figure 6 is another schematic diagram of the synchronization signal provided in an embodiment of the present application. As shown in Figure 6, in the synchronization signal, the first information and the fourth information can be mapped to the physical resource blocks in an equally spaced manner in the frequency domain, and the second information and the third information are mapped to at least one continuous physical resource block in the frequency domain.

[0204] Optionally, when the physical resource blocks mapped by the first information and the fourth information are equally spaced in the frequency domain, the distribution positions of the physical resource blocks mapped by the first information and the physical resource blocks mapped by the fourth information are the same.

[0205] Optionally, the starting distribution position of at least one continuous physical resource block mapped by the second information and the third information in the frequency domain is the same in the frequency domain, and the starting distribution position is the same as the distribution position of any physical resource block mapped by the fourth information or the first information.

[0206] For example, the starting distribution position of at least one continuous physical resource block mapped in the frequency domain by the second information and the third information in FIG6 is the same as the distribution position of the fifth physical resource block mapped by the first information and the fourth information.

[0207] Optionally, the starting position of each physical resource block is configured and / or pre-configured by higher layer signaling.

[0208] Optionally, the starting position of each interlace is configured and / or pre-configured by higher layer signaling.

[0209] This example adjusts the distribution positions of the physical resource blocks mapped by the first information and the fourth information in the frequency domain so that the bandwidth range occupied by the synchronization signal in frequency meets regulatory requirements (such as OCB>80%). In addition, the increase in bandwidth can also correspondingly increase the transmission power of the synchronization signal, thereby helping to improve the signal coverage effect.

[0210] Example 4

[0211] The physical resource blocks mapped by the first information, the second information and the third information are continuously distributed in the frequency domain, and the physical resource blocks mapped by the fourth information are frequency-hopping distributed in the frequency domain. Optionally, frequency-hopping distribution means that the content contained in the fourth information is distributed in different positions in the frequency domain.

[0212] Optionally, to implement frequency hopping distribution, the fourth information includes at least two sub-information at different time domain locations, for example, first sub-information and second sub-information at different time domain locations. For another example, first sub-information, second sub-information, and third sub-information at different time domain locations may be included.

[0214] For example, Figure 7 is another schematic diagram of the synchronization signal provided by an embodiment of the present application. As shown in Figure 7, in the synchronization signal, the first information, the second information and the third information are mapped to at least one continuous physical resource block in the frequency domain, the physical resource blocks mapped by the first sub-information in the fourth information are continuously distributed at the first frequency domain position in the frequency domain, and the physical resource blocks mapped by the second sub-information are continuously distributed at the second frequency domain position in the frequency domain.

[0215] Optionally, the first frequency domain position includes a first end of the frequency domain, such as the top of the frequency domain in Figure 7, and the second frequency domain position includes a second end of the frequency domain opposite to the first end, such as the bottom of the frequency domain in Figure 7.

[0216] Optionally, the first frequency domain position and / or the second frequency domain position is configured and / or pre-configured by higher layer signaling.

[0217] Optionally, the starting position of each physical resource block is configured and / or pre-configured by higher layer signaling.

[0218] Optionally, the starting position of each frequency hopping resource is configured and / or pre-configured by higher layer signaling.

[0219] This example adjusts the distribution position of the physical resource blocks mapped by the fourth information in the frequency domain so that the bandwidth range occupied by the synchronization signal in frequency meets regulatory requirements (such as OCB>80%). In addition, the increase in bandwidth can also correspondingly increase the transmission power of the synchronization signal, thereby helping to improve the signal coverage effect.

[0221] The physical resource blocks mapped by the first information are non-continuously distributed in the frequency domain, the physical resource blocks mapped by the second information and the third information are continuously distributed in the frequency domain, and the physical resource blocks mapped by the fourth information are frequency-hoppingly distributed in the frequency domain. Optionally, the frequency-hopping distribution means that the content contained in the fourth information is distributed at different positions in the frequency domain.

[0222] Optionally, the physical resource blocks mapped by the first information are non-continuously distributed in the frequency domain, and specifically can be mapped to the physical resource blocks in an equally spaced manner. The equally spaced physical resource blocks can be understood as a comb structure in the frequency domain. The comb structure is called interleaving, and the entire carrier bandwidth or resource pool is divided into several interleavings. Optionally, the number of interleavings is negatively correlated with the subcarrier spacing. For example, when the subcarrier spacing is 15kHz, it is divided into 10 interleavings, and when the subcarrier spacing is 30kHz, it is divided into 5 interleavings. Therefore, for a subcarrier spacing of 15 / 30kHz, each 10th / 5th resource block belongs to the same interleaving.

The starting distribution position of at least one continuous physical resource block mapped by the second information and the third information in the frequency domain is the same in the frequency domain, and the starting distribution position is the same as the distribution position of the 5th physical resource block mapped by the first information.

[0228] 8 , the physical resource blocks mapped by the first sub-information in the fourth information are continuously distributed at first frequency domain positions in the frequency domain, and the physical resource blocks mapped by the second sub-information are continuously distributed at second frequency domain positions in the frequency domain.

[0234] This example adjusts the distribution positions of the physical resource blocks mapped by the first information and the fourth information in the frequency domain so that the bandwidth range occupied by the synchronization signal in frequency meets regulatory requirements (such as OCB>80%). In addition, the increase in bandwidth can also correspondingly increase the transmission power of the synchronization signal, thereby helping to improve the signal coverage effect.

[0237] Optionally, the physical resource blocks mapped by the first information, the second information, the third information, and the physical resource blocks mapped by the fourth information are non-continuously distributed in the frequency domain, and specifically may be mapped to the physical resource blocks in an equally spaced manner. The equally spaced physical resource blocks can be understood as a comb structure in the frequency domain. The comb structure is called interleaving, and the entire carrier bandwidth or resource pool is divided into several interleavings. Optionally, the number of interleavings is negatively correlated with the subcarrier spacing, for example, when the subcarrier spacing is 15kHz, it is divided into 10 interleavings, and when the subcarrier spacing is 30kHz, it is divided into 5 interleavings. Therefore, for a subcarrier spacing of 15 / 30kHz, each 10th / 5th resource block belongs to the same interleaving.
