Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a synchronization signal mapping method, apparatus, computer device, and storage medium. Background Technology

[0002] When the system's synchronization signal beam covers the terminal, the terminal can achieve connection between the terminal and the system by mapping time-frequency domain resources through the synchronization signal.

[0003] To ensure that the synchronization signal beam can cover more terminals, a reconfigurable smart surface can be deployed, allowing the synchronization signal beam to be reflected through the reconfigurable smart surface, thereby enabling the reflected synchronization signal beam to cover more terminals.

[0004] However, as the number of terminals covered by the synchronization signal beam increases during the above process, the access competition among terminals when mapping synchronization signal time and frequency domain resources also gradually increases, which in turn makes it difficult for some terminals to access the system smoothly. Summary of the Invention

[0005] Therefore, it is necessary to provide a synchronization signal mapping method, apparatus, computer equipment, and storage medium that can ensure smooth access of terminals to the system, addressing the aforementioned technical problems.

[0006] Firstly, this application provides a synchronization signal mapping method. The method includes:

[0007] Based on the reflection of the synchronization signal by the reconfigurable smart surface, the synchronization signal is classified to obtain the classified synchronization signal; the classified synchronization signal includes a first synchronization signal covering the reconfigurable smart surface, and / or a second synchronization signal not covering the reconfigurable smart surface;

[0008] These are time-frequency domain resources mapped to the classified synchronization signals.

[0009] In one embodiment, the synchronization signal is classified based on the reflection of the synchronization signal by the reconfigurable smart surface, resulting in classified synchronization signals, including:

[0010] Synchronization signals are classified based on whether they receive a synchronization signal from a reconfigurable smart surface, resulting in classified synchronization signals.

[0011] In one embodiment, the synchronization signals are classified according to whether a synchronization signal identifier of reconfigurable smart surface feedback is received, resulting in classified synchronization signals, including:

[0012] If a synchronization signal identifier is received from the reconfigurable smart surface, the synchronization signal is identified as the first synchronization signal covering the reconfigurable smart surface.

[0013] If no synchronization signal identifier is received from the reconfigurable smart surface, the synchronization signal is determined to be the second synchronization signal that does not cover the reconfigurable smart surface.

[0014] In one embodiment, the method further includes:

[0015] Send a synchronization signal identifier to the reconfigurable smart surface.

[0016] In one embodiment, mapping time-frequency domain resources to the classified synchronization signals includes:

[0017] Within a synchronization signal mapping cycle, time-frequency domain resources are allocated to the first and second synchronization signals according to preset mapping principles and mapping-related parameters.

[0018] In one embodiment, the preset mapping principle includes at least one of the following:

[0019] Within one synchronization signal mapping cycle, the second synchronization signal is mapped first, and then the first synchronization signal is mapped.

[0020] The mapping of the first and second synchronization signals follows the order of increasing frequency domain first and then increasing time domain.

[0021] The time-frequency domain resources allocated by the first synchronization signal and the time-frequency domain resources allocated by the second synchronization signal do not occupy the same time-domain resources;

[0022] The contention for preambles in the time-frequency domain resources allocated by the first synchronization signal and the time-frequency domain resources allocated by the second synchronization signal are both incremented according to the preamble index value.

[0023] In one embodiment, the mapping-related parameters include: the number of synchronization signals, the number of time-frequency domain resources corresponding to the synchronization signals, the total number of preambles on each time-frequency domain resource corresponding to the synchronization signals, the correspondence between synchronization signals and time-frequency domain resources, and the total number of competing preambles within each synchronization signal.

[0024] Secondly, this application also provides a synchronization signal mapping device. The device includes:

[0025] The classification module is used to classify the synchronization signal according to the reflection of the synchronization signal by the reconfigurable smart surface, and obtain the classified synchronization signal; the classified synchronization signal includes a first synchronization signal covering the reconfigurable smart surface, and / or a second synchronization signal not covering the reconfigurable smart surface;

[0026] The mapping module is used to map time-frequency domain resources to the classified synchronization signals respectively.

[0027] Thirdly, this application also provides a computer device. The computer device includes a memory and a processor, the memory storing a computer program, and the processor executing the computer program to perform the following steps:

[0028] Based on the reflection of the synchronization signal by the reconfigurable smart surface, the synchronization signal is classified to obtain the classified synchronization signal; the classified synchronization signal includes a first synchronization signal covering the reconfigurable smart surface, and / or a second synchronization signal not covering the reconfigurable smart surface;

[0029] These are time-frequency domain resources mapped to the classified synchronization signals.

[0030] Fourthly, this application also provides a computer-readable storage medium. The computer-readable storage medium stores a computer program thereon, which, when executed by a processor, performs the following steps:

[0031] Based on the reflection of the synchronization signal by the reconfigurable smart surface, the synchronization signal is classified to obtain the classified synchronization signal; the classified synchronization signal includes a first synchronization signal covering the reconfigurable smart surface, and / or a second synchronization signal not covering the reconfigurable smart surface;

[0032] These are time-frequency domain resources mapped to the classified synchronization signals.

[0033] Fifthly, this application also provides a computer program product. The computer program product includes a computer program that, when executed by a processor, performs the following steps:

[0034] Based on the reflection of the synchronization signal by the reconfigurable smart surface, the synchronization signal is classified to obtain the classified synchronization signal; the classified synchronization signal includes a first synchronization signal covering the reconfigurable smart surface, and / or a second synchronization signal not covering the reconfigurable smart surface;

[0035] These are time-frequency domain resources mapped to the classified synchronization signals.

[0036] The aforementioned synchronization signal mapping method, apparatus, computer equipment, and storage medium determine the first and second synchronization signals based on the reflection of the synchronization signal by the reconfigurable smart surface, and map time-frequency domain resources for the first and second synchronization signals respectively. Since the above process maps time-frequency domain resources for the first and second synchronization signals separately, compared to the scheme of mapping time-frequency domain resources for all synchronization signals simultaneously, this application maps time-frequency domain resources for each synchronization signal separately, ensuring that each synchronization signal has its own time-frequency domain resources. There is no resource competition between synchronization signals, which improves the flexibility of mapping time-frequency domain resources for synchronization signals. At the same time, it reduces access competition between different terminals, enabling all terminals covered by the synchronization signal beam to successfully access the system.

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0050] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application. In the description of this application, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0051] The synchronization signal mapping method provided in this application can be applied to, for example... Figure 1 In the application environment shown, when the reconfigurable smart surface 102 is deployed within the beam range of the synchronization signal corresponding to the base station 104, it can reflect the beam range of the synchronization signal, such as... Figure 1 In this process, the reconfigurable smart surface 102 reflects the synchronization signal 1. Specifically, based on the reflection of the synchronization signal by the reconfigurable smart surface 102, a first synchronization signal and a second synchronization signal are determined, and time-frequency domain resources are mapped to the first synchronization signal and the second synchronization signal, respectively. The base station 104 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0052] In one embodiment, such as Figure 2 As shown, a synchronization signal mapping method is provided, which can be applied to... Figure 1 Taking a base station as an example, the explanation includes the following steps:

[0053] Step 201: Based on the reflection of the synchronization signal by the reconfigurable smart surface, classify the synchronization signal to obtain the classified synchronization signal.

[0054] The classified synchronization signals include a first synchronization signal covering the reconfigurable smart surface and / or a second synchronization signal not covering the reconfigurable smart surface. Further, the first synchronization signal can be represented as ESSB (Extended Single Side Band) and the second synchronization signal can be represented as NSSB (Normal Single Side Band).

[0055] It should be noted that the reflection of synchronization signals by the reconfigurable smart surface includes both situations where the reconfigurable smart surface reflects the synchronization signal and situations where the reconfigurable smart surface does not reflect the synchronization signal. To further clarify, when the reconfigurable smart surface is deployed within the beam range of a synchronization signal, it can reflect the beam range of that synchronization; when the reconfigurable smart surface is deployed outside the beam range of a synchronization signal, it will not reflect the beam range of that synchronization.

[0056] For example, in one embodiment of this application, such as Figure 3 As shown in the figure, the beam ranges of synchronization signals Q and P are as follows. The reconfigurable smart surface is deployed within the beam range a of synchronization signal Q. Therefore, the reconfigurable smart surface reflects the beam range a of synchronization signal Q, and the reflected range is the beam range b of synchronization signal Q. Since the reconfigurable smart surface is deployed outside the beam range c of synchronization signal P, it will not reflect the beam range c of synchronization signal P.

[0057] This can be understood as follows: when it is necessary to determine the reflection of a synchronization signal by a reconfigurable smart surface, it can be determined whether the deployment location of the reconfigurable smart surface is within the beam range of the synchronization signal; if the deployment location of the reconfigurable smart surface is within the beam range of the synchronization signal, it is determined that the reconfigurable smart surface reflects the synchronization signal; similarly, if the deployment location of the reconfigurable smart surface is outside the beam range of the synchronization signal, it is determined that the reconfigurable smart surface does not reflect the synchronization signal.

[0058] In one embodiment of this application, a synchronization signal identifier can be sent to the reconfigurable smart surface to determine the reflection status of the synchronization signal by the reconfigurable smart surface. Specifically, all synchronization signals are scanned in advance to determine the synchronization signal identifiers of all synchronization signals. The synchronization signal identifier is then sent to the reconfigurable smart surface. If the reconfigurable smart surface is within the beam range of the synchronization signal, it will respond with the synchronization signal identifier; otherwise, it will not respond with the synchronization signal identifier. Therefore, after sending the synchronization signal identifier to the reconfigurable smart surface, the reflection status of the synchronization signal by the reconfigurable smart surface can be determined by judging whether a synchronization signal identifier is received from the reconfigurable smart surface.

[0059] Among them, the synchronization signal identifier refers to the identity identifier corresponding to the synchronization signal, and the identity identifier corresponding to different synchronization signals is different.

[0060] As an example, after sending a synchronization signal identifier to the reconfigurable smart surface, if a synchronization signal identifier is received from the reconfigurable smart surface, it indicates that the deployment location of the reconfigurable smart surface is within the beam range of the synchronization signal. In this case, it is determined that the reconfigurable smart surface reflects the synchronization signal, and therefore, the synchronization signal corresponding to the synchronization signal identifier is determined as the first synchronization signal covering the reconfigurable smart surface. If no synchronization signal identifier is received from the reconfigurable smart surface, it indicates that the deployment location of the reconfigurable smart surface is outside the beam range of the synchronization signal. In this case, it is determined that the reconfigurable smart surface does not reflect the synchronization signal, and therefore, the synchronization signal corresponding to the synchronization signal identifier is determined as the second synchronization signal not covering the reconfigurable smart surface.

[0061] In another embodiment of this application, the deployment location of the reconfigurable smart surface and the beam range of each synchronization signal can be predetermined. Then, based on the deployment location of the reconfigurable smart surface and the beam range of each synchronization signal, it is determined whether a reconfigurable smart surface is deployed within the beam range of the synchronization signal. If a reconfigurable smart surface is deployed within the beam range of the synchronization signal, the synchronization signal with the reconfigurable smart surface deployed within the beam range is taken as the first synchronization signal. Furthermore, the synchronization signal without the reconfigurable smart surface deployed within the beam range is taken as the second synchronization signal.

[0062] Step 202 involves mapping the time-frequency domain resources of the classified synchronization signals.

[0063] It should be noted that, in order to reduce access competition between different terminals and ensure that all terminals covered by the synchronization signal beam can successfully access the system, the classified synchronization signals need to be mapped to time-frequency domain resources in batches according to their categories.

[0064] In one embodiment of this application, if the classified synchronization signal includes a first synchronization signal covering the reconfigurable smart surface and / or a second synchronization signal not covering the reconfigurable smart surface, when it is necessary to map time-frequency domain resources for the synchronization signal, in order to reduce access competition between different terminals, the first synchronization signal can be mapped to time-frequency domain resources first, and then the second synchronization signal can be mapped to time-frequency domain resources.

[0065] In another embodiment of this application, if the classified synchronization signal includes a first synchronization signal covering the reconfigurable smart surface and / or a second synchronization signal not covering the reconfigurable smart surface; when it is necessary to map time-frequency domain resources for the synchronization signal, in order to reduce access competition between different terminals, time-frequency domain resources can be mapped for the second synchronization signal first, and then time-frequency domain resources can be mapped for the first synchronization signal.

[0066] To further explain, when it is necessary to map time-frequency domain resources to the classified synchronization signals, time-frequency domain resources can be allocated to the classified synchronization signals according to the preset mapping principles and the mapping-related parameters of the classified synchronization signals.

[0067] The preset mapping principles may include, but are not limited to: within a synchronization signal mapping period, the mapping order of different types of synchronization signals, the mapping order of the same type of synchronization signals, the time-frequency domain resources allocated to different types of synchronization signals not occupying the same time-frequency domain resources, and the competing preambles in the time-frequency domain resources allocated to different types of synchronization signals all increasing according to the preamble index value, etc.

[0068] Among them, the mapping parameters of the classified synchronization signals may include, but are not limited to: the number of synchronization signals, the number of time-frequency domain resources corresponding to the synchronization signals, the total number of preambles on each time-frequency domain resource corresponding to the synchronization signals, the correspondence between synchronization signals and time-frequency domain resources, and the total number of competing preambles in each synchronization signal.

[0069] The aforementioned synchronization signal mapping method determines the first and second synchronization signals based on the reflection of the synchronization signal by the reconfigurable smart surface, and maps time-frequency domain resources for the first and second synchronization signals respectively. Since the process maps time-frequency domain resources for the first and second synchronization signals separately, this application, compared to the scheme of mapping time-frequency domain resources for all synchronization signals simultaneously, maps time-frequency domain resources for each synchronization signal separately. This ensures that each synchronization signal has its own time-frequency domain resources, eliminating resource competition between synchronization signals, improving the flexibility of mapping time-frequency domain resources for synchronization signals, and reducing access competition between different terminals, allowing all terminals covered by the synchronization signal beam to successfully access the system.

[0070] It should be noted that when classifying synchronization signals, it is possible to determine which synchronization signals are reflected by the reconfigurable smart surface and which are not. Then, the synchronization signals reflected by the reconfigurable smart surface are classified into one type of synchronization signal, and the synchronization signals not reflected by the reconfigurable smart surface are classified into another type of synchronization signal.

[0071] To further explain, when it is necessary to determine whether a certain synchronization signal is reflected by a reconfigurable smart surface, the synchronization signal identifier of the synchronization signal can be sent to the reconfigurable smart surface. Based on whether the synchronization signal identifier is received from the reconfigurable smart surface, the synchronization signal is classified to obtain the classified synchronization signal.

[0072] In one embodiment of this application, if a reconfigurable smart surface is deployed within the beam range of synchronization signal A, and a synchronization signal identifier of synchronization signal B is sent to the reconfigurable smart surface, the reconfigurable smart surface will not respond with a synchronization signal identifier because it is deployed within the beam range of synchronization signal A. If a synchronization signal identifier of synchronization signal A is sent to the reconfigurable smart surface, the reconfigurable smart surface will respond with a synchronization signal identifier of synchronization signal A because it is deployed within the beam range of synchronization signal A. In this case, synchronization signal A and synchronization signal B can be classified into two different types of synchronization signals.

[0073] Among them, the synchronization signal reflected by the reconfigurable smart surface is the first synchronization signal, and the synchronization signal not reflected by the reconfigurable smart surface is the first synchronization signal.

[0074] The aforementioned synchronization signal mapping method classifies synchronization signals by determining whether a synchronization signal identifier is received from the reconfigurable smart surface. This provides the foundation for mapping time-frequency domain resources to the classified synchronization signals, preventing significant access contention between terminals when mapping time-frequency domain resources to all synchronization signals simultaneously.

[0075] In one embodiment, the synchronization signal can be divided into a first synchronization signal and a second synchronization signal based on whether a synchronization signal identifier of the reconfigurable smart surface feedback is received, such as... Figure 4 As shown, the method specifically includes the following:

[0076] Step 401: If a synchronization signal identifier is received from the reconfigurable smart surface, the synchronization signal is determined as the first synchronization signal covering the reconfigurable smart surface.

[0077] It should be noted that by sending a synchronization signal identifier of a certain synchronization signal to the reconfigurable smart surface, if the synchronization signal identifier of the synchronization signal is received back from the reconfigurable smart surface, then the synchronization signal is determined as the first synchronization signal covering the reconfigurable smart surface.

[0078] If the synchronization signal identifier of the synchronization signal is received from the reconfigurable smart surface, it indicates that the reconfigurable smart surface is deployed within the beam range of the synchronization signal.

[0079] For example, when it is necessary to verify whether synchronization signal C is the first synchronization signal, the synchronization signal identifier of synchronization signal C is sent to the reconfigurable smart surface. If no synchronization signal identifier is received from the reconfigurable smart surface, it is determined that synchronization signal C is not the first synchronization signal; if a synchronization signal identifier is received from the reconfigurable smart surface, it is determined that synchronization signal C is the first synchronization signal.

[0080] Step 402: If no synchronization signal identifier is received from the reconfigurable smart surface, the synchronization signal is determined to be the second synchronization signal that does not cover the reconfigurable smart surface.

[0081] It should be noted that if a synchronization signal identifier of a certain synchronization signal is sent to the reconfigurable smart surface, and no synchronization signal identifier of the same synchronization signal is received from the reconfigurable smart surface, then the synchronization signal is determined to be a second synchronization signal that does not cover the reconfigurable smart surface.

[0082] If the synchronization signal identifier of the synchronization signal fed back by the reconfigurable smart surface is not received, it means that the reconfigurable smart surface is deployed outside the beam range of the synchronization signal.

[0083] For example, when it is necessary to verify whether the synchronization signal D is the second synchronization signal, the synchronization signal identifier of the synchronization signal D is sent to the reconfigurable smart surface. If the synchronization signal identifier is received from the reconfigurable smart surface, it is determined that the synchronization signal D is not the second synchronization signal; if the synchronization signal identifier is not received from the reconfigurable smart surface, it is determined that the synchronization signal D is the second synchronization signal.

[0084] The aforementioned synchronization signal mapping method determines whether the reconfigurable smart surface is deployed within the beam range of the synchronization signal by judging whether a synchronization signal identifier fed back from the reconfigurable smart surface is received. This allows the synchronization signal to be divided into a first synchronization signal and a second synchronization signal. Subsequently, time-frequency domain resources are mapped to the synchronization signal in batches using the first and second synchronization signals, improving the flexibility of mapping time-frequency domain resources for the synchronization signal. This reduces access competition between different terminals, ensuring that all terminals covered by the synchronization signal beam can successfully access the system.

[0085] It should be noted that, in order to map the time-frequency domain resources of the first synchronization signal and the second synchronization signal in batches, the following may be included: within a synchronization signal mapping cycle, time-frequency domain resources are allocated to the first synchronization signal and the second synchronization signal according to the preset mapping principle and mapping-related parameters.

[0086] The preset mapping principle includes at least one of the following: within a synchronization signal mapping period, the second synchronization signal is mapped first, followed by the first synchronization signal; the mapping of the first synchronization signal and the mapping of the second synchronization signal are both in the order of increasing frequency domain first and increasing time domain; the time-frequency domain resources allocated to the first synchronization signal and the time-frequency domain resources allocated to the second synchronization signal do not occupy the same time domain resources; the contention preambles in the time-frequency domain resources allocated to the first synchronization signal and the time-frequency domain resources allocated to the second synchronization signal are both in the order of increasing preamble index value.

[0087] The mapping-related parameters include: the number of synchronization signals, the number of time-frequency domain resources corresponding to the synchronization signals, the total number of preambles on each time-frequency domain resource corresponding to the synchronization signals, the correspondence between synchronization signals and time-frequency domain resources, and the total number of competing preambles within each synchronization signal.

[0088] Furthermore, the number of synchronization signals in the mapping-related parameters can be represented as SSB Number, where the number of the first synchronization signal can be represented as ESSB Number; and the number of the second synchronization signal can be represented as NSSB Number.

[0089] Furthermore, the number of time-frequency domain resources corresponding to the synchronization signal in the mapping-related parameters can be represented as msg1-FDM-SSB, where the number of time-frequency domain resources corresponding to the first synchronization signal can be represented as msg1-FDM-ESSB, and the number of time-frequency domain resources corresponding to the second synchronization signal can be represented as msg1-FDM-NSSB.

[0090] Furthermore, the total number of preambles on each time-frequency domain resource corresponding to the synchronization signal in the mapping-related parameters can be expressed as: totalNumberOfRA-Preambles-SSB, where the total number of preambles on each time-frequency domain resource corresponding to the first synchronization signal can be expressed as: totalNumberOfRA-Preambles-ESSB; and the total number of preambles on each time-frequency domain resource corresponding to the second synchronization signal can be expressed as: totalNumberOfRA-Preambles-NSSB.

[0091] Furthermore, the correspondence between the synchronization signal and the time-frequency domain resources in the mapping-related parameters can be expressed as: SSB-perRACH-Occasion, where the correspondence between the first synchronization signal and the time-frequency domain resources can be expressed as: ESSB-perRACH-Occasion; and the correspondence between the second synchronization signal and the time-frequency domain resources can be expressed as: NSSB-perRACH-Occasion.

[0092] Furthermore, the total number of contention preambles within the synchronization signal in the mapping-related parameters can be expressed as: CB - preambles - per - SSB, where the total number of contention preambles within the first synchronization signal can be expressed as: CB - preambles - per - ESSB; and the total number of contention preambles within the second synchronization signal can be expressed as: CB - preambles - per - NSSB. The number of available contention preambles within each time-frequency domain resource is: CB - preambles - per - SSB * max(1, SSB - per RACH - Occasion).

[0093] In one embodiment of this application, when it is necessary to map time-frequency domain resources to eight synchronization signals, the following may be included: the eight synchronization signals are: synchronization signal 0, synchronization signal 1, synchronization signal 2, synchronization signal 3, synchronization signal 4, synchronization signal 5, synchronization signal 6, and synchronization signal 7. Based on the synchronization signal identifiers of the eight synchronization signals received from the reconfigurable smart surface feedback, synchronization signals 3 and 7 are determined to be the first synchronization signals, and synchronization signals 0, 1, 2, 4, 5, and 6 are determined to be the second synchronization signals. Therefore, the eight synchronization signals can be represented as: first synchronization signal 0, first synchronization signal 1, second synchronization signal 0, second synchronization signal 1, second synchronization signal 2, second synchronization signal 3, second synchronization signal 4, and second synchronization signal 5.

[0094] Further explanation: The mapping parameters for the first synchronization signal are as follows: the number of first synchronization signals is 2, the number of time-frequency domain resources corresponding to the first synchronization signal is 4, the total number of preambles on each time-frequency domain resource corresponding to the first synchronization signal is 64, the correspondence between the first synchronization signal and the time-frequency domain resource is 1 / 4, and the total number of contention preambles within each first synchronization signal is 32. The mapping parameters for the second synchronization signal are as follows: the number of second synchronization signals is 6, the number of time-frequency domain resources corresponding to the second synchronization signal is 4, the total number of preambles on each time-frequency domain resource corresponding to the second synchronization signal is 64, the correspondence between the second synchronization signal and the time-frequency domain resource is 1, and the total number of contention preambles within each second synchronization signal is 20.

[0095] The correspondence between the first synchronization signal and the time-frequency domain resources is represented by 1 / 4, with one first synchronization signal corresponding to four time-frequency domain resources. Similarly, the correspondence between the second synchronization signal and the time-frequency domain resources is represented by 1, with one second synchronization signal corresponding to one time-frequency domain resource.

[0096] Based on the aforementioned preset mapping principles and mapping-related parameters, a mapping diagram of the first synchronization signal and the second synchronization signal is constructed, as shown in the figure below. Figure 5 As shown, therefore, according to the mapping diagram, the second synchronization signal is first mapped to the contention preamble in the time-frequency domain resources: 0-19; then the first synchronization signal is mapped to the contention preamble in the time-frequency domain resources: 0-31.

[0097] The above-mentioned synchronization signal mapping method allocates time-frequency domain resources to the first and second synchronization signals by pre-setting mapping principles and mapping-related parameters. This enables the mapping of time-frequency domain resources to synchronization signals in batches, improving the flexibility of mapping time-frequency domain resources to synchronization signals. Consequently, it reduces access competition between different terminals, ensuring that all terminals covered by the synchronization signal beam can successfully access the system.

[0098] In one embodiment, when it is necessary to map time-frequency domain resources for synchronization signals, then as follows: Figure 6 As shown, it may specifically include the following:

[0099] Step 601: Send a synchronization signal identifier to the reconfigurable smart surface.

[0100] Step 602: If a synchronization signal identifier is received from the reconfigurable smart surface, the synchronization signal is determined as the first synchronization signal covering the reconfigurable smart surface.

[0101] Step 603: If no synchronization signal identifier is received from the reconfigurable smart surface, the synchronization signal is determined to be the second synchronization signal that does not cover the reconfigurable smart surface.

[0102] Step 604: Within one synchronization signal mapping cycle, allocate time-frequency domain resources to the first synchronization signal and the second synchronization signal according to the preset mapping principle and mapping-related parameters.

[0103] The aforementioned synchronization signal mapping method determines the first and second synchronization signals based on the reflection of the synchronization signal by the reconfigurable smart surface, and maps time-frequency domain resources for the first and second synchronization signals respectively. Since the process maps time-frequency domain resources for the first and second synchronization signals separately, this application, compared to the scheme of mapping time-frequency domain resources for all synchronization signals simultaneously, maps time-frequency domain resources for each synchronization signal separately. This ensures that each synchronization signal has its own time-frequency domain resources, eliminating resource competition between synchronization signals, improving the flexibility of mapping time-frequency domain resources for synchronization signals, and reducing access competition between different terminals, allowing all terminals covered by the synchronization signal beam to successfully access the system.

[0104] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0105] Based on the same inventive concept, this application also provides a synchronization signal mapping apparatus for implementing the synchronization signal mapping method described above. The solution provided by this apparatus is similar to the implementation described in the above method; therefore, the specific limitations in one or more synchronization signal mapping apparatus embodiments provided below can be found in the limitations of the synchronization signal mapping method described above, and will not be repeated here.

[0106] In one embodiment, such as Figure 7 As shown, a synchronization signal mapping device is provided, including: a classification module 10 and a mapping module 20, wherein:

[0107] The classification module 10 is used to classify the synchronization signal according to the reflection of the synchronization signal by the reconfigurable smart surface, and obtain the classified synchronization signal; the classified synchronization signal includes a first synchronization signal covering the reconfigurable smart surface, and / or a second synchronization signal not covering the reconfigurable smart surface.

[0108] The mapping module 20 is used to map time-frequency domain resources to the classified synchronization signals respectively.

[0109] The aforementioned synchronization signal mapping device determines the first and second synchronization signals based on the reflection of the synchronization signal by the reconfigurable smart surface, and maps time-frequency domain resources for the first and second synchronization signals respectively. Since the process maps time-frequency domain resources for the first and second synchronization signals separately, this application, compared to the scheme of mapping time-frequency domain resources for all synchronization signals simultaneously, maps time-frequency domain resources for each synchronization signal separately.
