[0043] The embodiments of this disclosure will be described in detail below with reference to the accompanying drawings and examples.

[0044] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0045] The methods and embodiments provided in this disclosure can be executed in a computer device or similar computing device. Taking a computer device as an example, FIG1 is a hardware structure block diagram of a computer device for the communication parameter sending and receiving method of this disclosure. As shown in FIG1, the computer device may include one or more (only one is shown in FIG1) processors 102 (processor 102 may include, but is not limited to, processing devices such as microprocessors MCUs or programmable logic devices) and a memory 104 for storing data. The computer device may also include a transmission device 106 for communication functions and an input / output device 108. It will be understood by those skilled in the art that the structure shown in FIG1 is only illustrative and does not limit the structure of the computer device. For example, the computer device may also include more or fewer components than shown in FIG1, or have a different configuration than shown in FIG1.

[0046] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the communication parameter sending and receiving method in this embodiment. The processor 102 executes various functional applications and single-board matching by running the computer program stored in the memory 104, thus implementing the above-described method. The memory 104 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to computer devices via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0047] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by a communication provider for the computer equipment. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module used for wireless communication with the Internet.

[0048] This embodiment provides a method for sending communication parameters on the aforementioned computer device. Figure 2 is a flowchart of the method for sending communication parameters according to an embodiment of this disclosure. As shown in Figure 2, the method is applied to a control node (UE), and the process includes the following steps:

[0049] Step S202: Send a synchronization signal block SSB to the member UE, wherein the SSB is used to determine the time-frequency resources of the feedback resources and the time-frequency resources carrying the communication parameters.

[0050] Step S204: Receive communication parameter request information from the member UE on the time-frequency resources of the feedback resource;

[0051] Step S206: Send the corresponding communication parameters to the member UE on the time-frequency resources carrying the communication parameters.

[0052] The SSB in this embodiment may specifically include multiple synchronization sequences, a broadcast channel, and is also used for time slot synchronization and symbol synchronization with member UEs.

[0053] Through the above steps S202 to S206, the problem that member UEs cannot directly obtain necessary system communication parameters from the base station in the SL network composed of the control node and member UEs in the related technology can be solved, so that member UEs can obtain communication parameters from the control node UE.

[0054] Figure 3 is a schematic diagram of the control node UE and member UEs according to an embodiment of this disclosure. As shown in Figure 3, in sidelink communication, when there is a service transmission requirement between user equipments (UEs), the service data between UEs does not pass through the network side, that is, it does not pass through the cellular link between the UE and the base station for forwarding. Instead, it is directly transmitted from the data source UE to the target UE through the sidelink. In industrial field network scenarios, under the coverage of the base station, there are both directly connected UEs and some remote UEs. The remote UEs are directly connected to the control node UE. The small network composed of member UEs and control node UEs can be called a micronet. In the micronet, only the control node UE needs to be connected to the base station, and other UEs only need to establish a connection with the control node UE to realize communication between UEs or between UEs and the base station. This technology can reduce the burden on the cellular network, reduce the battery power consumption of user equipment, well meet the requirements of high data rate services and proximity services, and also support direct communication between devices in scenarios without network coverage, which can meet the low latency and high reliability communication requirements in industrial field networks.

[0055] This not only ensures synchronization between the control node and member UEs but also efficiently directs resource allocation information, reducing additional control signaling transmissions. It is particularly suitable for networks with large-scale IoT devices, improving network response speed and resource utilization efficiency. Through explicit time-frequency resource allocation, member UEs can send request information at specified times and frequencies, avoiding resource conflicts and enhancing communication reliability, especially in scenarios with high-density device deployments, such as smart cities and industrial automation. Precise resource positioning enables the control node to send communication parameters to member UEs in a timely and accurate manner, optimizing the data transmission process, which is beneficial for applications with high real-time requirements, such as telemedicine and autonomous driving.

[0056] Furthermore, step S202 above may specifically include: sending SSBs to member UEs at preset time intervals, wherein some or all of the SSBs are used to determine the time-frequency resources for feedback resources and the time-frequency resources carrying communication parameters. Periodic SSB transmission ensures continuous network synchronization and resource allocation continuity, making it suitable for dynamic network environments that require frequent updates to communication parameters, such as mobile networks and drone networks.

[0057] Figure 4 is a flowchart of a communication parameter transmission method according to an optional embodiment of the present disclosure. As shown in Figure 4, the above method further includes at least one of the following:

[0058] Step S402: The time-frequency resource location of the feedback resource is indicated by the SSB.

[0059] Step S404: The location of the time-frequency resource carrying the communication parameters is indicated by the SSB.

[0060] This additional information provides member UEs with more detailed resource location information, reducing the time and energy consumption of member UEs in resource search. Especially in energy-constrained devices, such as wearable devices and sensor nodes, it can significantly extend the device's battery life.

[0061] Further, step S402 can specifically include: if there is only one feedback resource, the time-domain and frequency-domain resource locations of the feedback resource are indicated through the PSBCH (Physical Sidelink Broadcast Channel) of the SSB; if there are multiple feedback resources, the time-domain and frequency-domain resource locations of the first feedback resource are indicated through the PSBCH channel of the SSB, and the time-domain and frequency-domain resource locations of the other feedback resources are determined according to the predefined time-domain and frequency-domain intervals between feedback resources and the time-domain and frequency-domain resource locations of the first feedback resource. This method of indicating resource locations enables member UEs to quickly locate feedback resources, especially when there are a large number of feedback resources, improving the flexibility and efficiency of resource allocation. It is suitable for scenarios involving parallel processing of multiple services, such as multimedia conferencing and multi-user games.

[0062] Further, indicating the time-domain resource location of the feedback resource via the PSBCH channel of the SSB can specifically include at least one of the following: indicating the time slot index of the feedback resource relative to the SSB time slot via the PSBCH channel of the SSB, wherein the starting symbol position of the feedback resource within the time slot is a predefined position within the time slot, and the time-domain duration of the feedback resource is a predefined length; indicating the time slot index of the feedback resource relative to the SSB and the starting symbol position within the time slot via the PSBCH channel of the SSB, wherein the time-domain duration of the feedback resource is a predefined length; indicating the symbol offset of the starting symbol of the feedback resource within the time slot relative to the time slot via the SSB, wherein the time slot location of the feedback resource is determined based on the SSB's reception processing time and the SSB time slot, and the time-domain duration of the feedback resource is a predefined length; indicating the feedback resource via the SSB... The system indexes feedback resources within the source's time slots, where the time slot location of the feedback resource is determined based on the SSB's reception processing time and the SSB time slot. The correspondence between the feedback resource index and the feedback resources within the time slot is a predefined correspondence. The PSBCH channel of the SSB indicates the relative displacement of the feedback resource's initial frequency domain location relative to a reference frequency domain location determined by the SSB. The frequency domain resource location of the feedback resource is determined based on the initial frequency domain location and the frequency domain size of the feedback resource, where the frequency domain size is a predefined size. The time-frequency resources of the feedback resource are within a predefined resource window, where the resource size is a predefined size. The predefined resource window includes N candidate resource locations, and the PSBCH channel of the SSB indicates the target candidate resource location. The predefined resource window includes both time domain and frequency domain ranges. Detailed time domain resource indication makes resource allocation more precise, reduces the search range of member UEs in the time domain, and improves communication timeliness. This is of significant value for applications requiring precise time synchronization, such as industrial control in Time-Sensitive Networks (TSNs). Precise indication of frequency domain resources optimizes spectrum utilization, especially in scenarios where spectrum resources are scarce, such as spectrum-sharing networks, 5G and future 6G networks, effectively avoiding spectrum waste and improving network capacity.

[0063] In one embodiment, the method further includes: if there are multiple feedback resources, indicating the feedback type on each feedback resource through the PSBCH channel of the SSB, wherein the feedback type corresponds to a specific set of devices or a specific set of services; or, the feedback type on each feedback resource determined by the PSBCH channel of the SSB is predefined, wherein the feedback type corresponds to a specific set of devices or a specific set of services. This indication of feedback types enables the network to prioritize resource allocation according to different device or service requirements, enhancing the network's intelligence and adaptability, and providing strong support for scenarios requiring differentiated services, such as high-definition video streaming, virtual reality (VR), and augmented reality (AR) applications.

[0064] In this embodiment of the disclosure, step S304 may specifically include at least one of the following: when the communication parameters at the physical layer only include a data channel, the time-frequency resource location of the data channel carrying the communication parameters is indicated through the broadcast channel of the SSB; when the communication parameters at the physical layer only include a control channel, the time-frequency resource location of the control channel carrying the communication parameters is indicated through the broadcast channel in the SSB, and the control channel is used to carry the communication parameters; when the communication parameters at the physical layer include both a control channel and a data channel, the time-frequency resource location of the control channel is indicated through the broadcast channel in the SSB, and the control channel is used to determine the time-frequency resource location of the data channel carrying the communication parameters. These resource indications for carrying communication parameters ensure efficient transmission of data and control information, reduce transmission latency, and have significant effects on scenarios requiring rapid response, such as emergency services and real-time communication.

[0065] Furthermore, indicating the time-frequency resource location of the data channel carrying communication parameters via the SSB's broadcast channel specifically includes: indicating the relative time slot index and relative frequency domain index of the time-frequency resource location of the communication parameters relative to the time-frequency resource location of a specific feedback resource determined according to the SSB; or, indicating the relative time slot index and relative frequency domain index of the time-frequency resource location of the communication parameters relative to the time-frequency resource location of the SSB. This indication of relative location simplifies the resource location process, reduces the computational complexity of resource search for member UEs, and can significantly reduce power consumption and processing latency for devices with limited computing power, such as Internet of Things (IoT) devices and edge computing nodes.

[0066] Furthermore, the above method also includes at least one of the following: determining the time-frequency resource location of the feedback resource for receiving communication parameter request information using the time-frequency resource location of the SSB and a first predefined rule; determining the time-frequency resource location carrying communication parameters using the time-frequency resource location of the SSB and a second predefined rule; and determining the time-frequency resource location carrying communication parameters using the time-frequency resource location of the feedback resource determined by the SSB and a third predefined rule. The application of these predefined rules makes the resource allocation process more automated and standardized, reduces the complexity of network configuration, and provides convenience for networks that require rapid deployment and large-scale expansion, such as massive MIMO systems and cloud radio access networks (C-RAN).

[0067] In one embodiment, determining the time-frequency resource location of the feedback resource based on the time-frequency resource location of the SSB and a first predefined rule may specifically include: determining the time slot location of the feedback resource based on the SSB's reception processing time and time slot, wherein the time slot symbol position within the time slot is a predefined position; and determining the frequency domain range of the feedback resource based on the SSB's frequency domain range and the first predefined rule. This resource location based on reception processing time and frequency domain range ensures timely resource allocation and effective spectrum utilization, providing a better user experience for scenarios requiring high bandwidth and low latency, such as high-definition video transmission and online games.

[0068] Furthermore, the frequency domain location of the feedback resource can be one of the following: a predefined feedback resource location among all candidate feedback resources within the frequency domain range of the feedback resource; any feedback resource location among all candidate feedback resources within the frequency domain range of the feedback resource; or, within the frequency domain range of the feedback resource, the frequency domain resource location is determined based on at least one of the following: the control node ID carried in the SSB, the number of candidate feedback resources within the frequency domain range of the feedback resource, the number of RBs within the frequency domain range of the feedback resource, the member UE ID, the member UE group ID, and the service ID. The feedback resource occupies K physically contiguous PRBs, or K logically contiguous PRBs. This flexible frequency domain resource location method can adapt to the spectrum requirements of different devices and services, enhancing the flexibility and scalability of the network, and is of great significance for spectrum resource management, especially in dynamic spectrum allocation and network slicing technologies.

[0069] In another embodiment, determining the time-frequency resource location of the feedback resource for receiving communication parameter request information using the time-frequency resource location of the SSB and a first predefined rule includes: if there is only one feedback resource, determining the time-domain and frequency-domain resource locations of the feedback resource using the time-frequency resource location of the SSB and the first predefined rule; if there are multiple feedback resources, determining the time-domain and frequency-domain resource locations of the first feedback resource using the time-frequency resource location of the SSB and the first predefined rule, and determining the time-domain and frequency-domain resource locations of other feedback resources according to the predefined time-domain and frequency-domain intervals between feedback resources and the time-domain and frequency-domain resource locations of the first feedback resource, wherein the other feedback resources are the feedback resources other than the first feedback resource among the multiple feedback resources. This resource determination method based on the time-frequency resource location of the SSB simplifies the resource allocation algorithm and improves the efficiency of resource allocation. For scenarios that need to handle a large number of device requests, such as large-scale IoT deployments and smart city management, it can significantly improve the network's processing capacity and response speed.

[0070] Furthermore, determining the time-frequency resource location carrying communication parameters through the time-frequency resource location of the SSB and the second predefined rule can specifically include: determining multiple candidate resource locations of the target channel carrying communication parameters within the resource window based on the time-frequency resource range of the SSB, wherein the target channel is one of the following: a data channel carrying communication parameters, a control channel carrying communication parameters, or a control channel corresponding to the data channel carrying communication parameters; or determining the time-frequency resource location of the target channel carrying communication parameters based on the reference time-domain resource location, reference frequency-domain resource location, predefined time-domain size, and predefined frequency-domain size determined by the time-frequency resource location of the SSB, wherein the target channel is one of the following: a data channel carrying communication parameters, a control channel carrying communication parameters, or a control channel corresponding to the data channel carrying communication parameters. This resource location determination based on the time-frequency resource range and predefined rules ensures reliable transmission of communication parameters, reduces transmission errors, and provides necessary guarantees for scenarios requiring high reliability, such as remote surgery and autonomous driving.

[0071] Further, determining multiple candidate resource positions of the target channel carrying communication parameters within the resource window based on the time-frequency resource range of the SSB may specifically include: obtaining the starting time-domain position M and the ending time-domain position N, the starting frequency-domain position P and the ending frequency-domain position Q of the resource window, wherein the time-domain resource size of the target channel is a, and the frequency-domain resource size is b; determining the starting time-domain positions of the candidate resource positions as M, M+a-1, M+2a-1, ..., M+na-1, and determining the starting frequency-domain positions of the candidate resource positions as P, P+b-1, P+2b-1, ..., P+mb-1, wherein M+na-1 is less than or equal to N, P+mb-1 is less than or equal to Q, and m and n are non-negative integers; or determining the starting time-domain positions of the candidate resource positions as M, M+1, M+2, ..., N-a+1, and determining the starting frequency-domain positions of the candidate resource positions as P, P+1, P+2, ..., Q-b+1.

[0072] The communication parameter transmission method of this disclosure, through the Synchronization Signal Block (SSB), not only achieves synchronization between the control node (UE) and member UEs, but also further indicates feedback resources and time-frequency resources carrying communication parameters, thereby simplifying the resource allocation process and improving communication efficiency. This method is particularly suitable for large-scale device networking scenarios, effectively reducing control signaling overhead, improving network resource utilization efficiency, and providing member UEs with a flexible and efficient communication parameter request and reception mechanism. Through predefined rules and SSB indications, member UEs can quickly locate feedback resources and communication parameter carrying resources, reducing unnecessary search time and enhancing the overall system performance. Furthermore, this method supports multi-service parallel processing, enabling priority allocation of resources according to different device and service requirements, improving network intelligence and adaptability. In practical applications, this method can significantly improve network response speed, resource utilization efficiency, and user experience, especially in scenarios such as the Internet of Things (IoT), industrial automation, high-definition video streaming, virtual reality and augmented reality applications, emergency services, and real-time communication, where its advantages are more pronounced. For the future development of 5G and 6G networks, this method provides an effective resource allocation and management strategy, contributing to the construction of more efficient, intelligent, and flexible communication networks.

[0073] This embodiment also provides a method for receiving communication parameters running on the aforementioned computer device. Figure 5 is a flowchart of the method for receiving communication parameters according to an embodiment of this disclosure. As shown in Figure 5, the method is applied to a member UE, and the process includes the following steps:

[0074] Step S502: Receive the synchronization signal block SSB sent by the control node UE, wherein the SSB is used to determine the time-frequency resources of the feedback resources and the time-frequency resources carrying the communication parameters;

[0075] Step S504: Feed back communication parameter request information to the control node UE on the time-frequency resources of the feedback resources;

[0076] Step S506: Receive communication parameters sent by the control node UE on the time-frequency resources carrying the communication parameters.

[0077] Through the above steps S502 to S506, the problem that member UEs cannot directly obtain necessary system communication parameters from the base station in the SL network composed of the control node and member UEs in the related technology can be solved, so that member UEs can obtain communication parameters from the control node UE.

[0078] Member UEs can quickly and accurately determine the resources for feedback and reception communication parameters, thereby improving communication efficiency and resource utilization. This approach is particularly effective in large-scale Internet of Things (IoT) networks, enabling efficient communication between devices and reducing resource conflicts.

[0079] Figure 6 is a flowchart of a communication parameter receiving method according to an embodiment of the present disclosure. As shown in Figure 6, the method further includes at least one of the following:

[0080] S602 determines the time-frequency resource location of the feedback resource through the instruction of SSB;

[0081] S604 determines the location of time-frequency resources carrying communication parameters through the SSB instruction.

[0082] Through steps S602 to S604, member UEs can flexibly adjust resource locations according to SSB instructions to adapt to different network environments and service requirements. In dynamic network environments, such as mobile networks or high-density user scenarios, this method can dynamically allocate resources, improving communication flexibility and reliability.

[0083] In this embodiment of the disclosure, step S602 may specifically include: if there is only one feedback resource, determining the time-domain and frequency-domain resource positions of the feedback resource through the indication of the PSBCH channel of the SSB; if there are multiple feedback resources, determining the time-domain and frequency-domain resource positions of the first feedback resource through the indication of the PSBCH channel of the SSB, and determining the time-domain and frequency-domain resource positions of the other feedback resources according to the predefined time-domain and frequency-domain intervals between feedback resources and the time-domain and frequency-domain resource positions of the first feedback resource. This method can ensure the orderly allocation of multiple feedback resources, avoid resource overlap, and is suitable for multi-service scenarios, such as network environments where video streaming, voice calls, and data transmission occur simultaneously, ensuring the communication quality of different services.

[0084] In one embodiment, determining the time-domain resource location of the feedback resource via the indication of the PSBCH channel of the SSB specifically includes at least one of the following: determining the time slot index of the feedback resource relative to the SSB time slot via the indication of the PSBCH channel of the SSB, wherein the starting symbol position of the feedback resource within the time slot is a predefined position within the time slot, and the time-domain duration of the feedback resource is a predefined length; determining the time slot index of the feedback resource relative to the SSB and the starting symbol position within the time slot via the indication of the PSBCH channel of the SSB, wherein the time-domain duration of the feedback resource is a predefined length. The method involves several steps: First, the initial symbol offset of the feedback resource within its time slot is determined by the SSB (Service Subscriber Block) indication. The time slot position of the feedback resource is determined based on the SSB's reception processing time and the SSB time slot itself. The duration of the feedback resource in the time domain is a predefined length. Second, the relative displacement of the feedback resource's initial frequency domain position to a reference frequency domain position determined by the SSB is indicated by the SSB's PSBCH channel. The frequency domain resource position of the feedback resource is determined based on its initial frequency domain position and its frequency domain size, which is also predefined. These time domain resource indication rules enable member UEs to accurately determine the time domain position of the feedback resource, avoiding wasted time domain resources and improving their utilization efficiency. In high-bandwidth scenarios, such as 5G or future 6G networks, this method effectively supports high-speed data transmission and reduces latency. This method of determining the frequency domain resource position simplifies the frequency domain resource allocation process, avoids conflicts, and is suitable for scenarios with limited spectrum resources, such as network deployments in urban centers, ensuring the effective utilization of spectrum resources.

[0085] Furthermore, in this embodiment of the present disclosure, the time-frequency resources of the feedback resources are within a predefined resource window. The resource size of the feedback resources is a predefined size, and the predefined resource window includes N candidate resource locations. The target candidate resource location is determined by the indication of the PSBCH channel of the SSB. The predefined resource window includes both a time domain range and a frequency domain range. The use of the predefined resource window and candidate resource locations makes resource allocation more orderly, reduces resource search time, is suitable for scenarios with strict resource management, and ensures the security and timeliness of communication.

[0086] Furthermore, if there are multiple feedback resources, the feedback type on each feedback resource is determined by the indication of the PSBCH channel of the SSB. The feedback type corresponds to a specific set of devices or a specific set of services. Alternatively, the feedback type on each feedback resource determined by the PSBCH channel of the SSB is predefined, where the feedback type corresponds to a specific set of devices or a specific set of services. This indication or predefinition of feedback types enables the network to allocate appropriate feedback resources according to different device or service requirements, enhancing the network's intelligence and service adaptability. In intelligent transportation systems, this method can effectively distinguish the feedback needs of vehicles and pedestrian devices, optimize resource allocation, and improve traffic safety.

[0087] In this embodiment of the disclosure, step S504 may specifically include: determining the relative time slot index and relative frequency domain index of the time-frequency resource location of the communication parameters relative to the time-frequency resource location of a specific feedback resource determined according to the SSB, through the indication of the broadcast channel of the SSB; or, determining the relative time slot index and relative frequency domain index of the time-frequency resource location of the communication parameters relative to the time-frequency resource location of the SSB, through the indication of the broadcast channel of the SSB. This relative indication of the time-frequency resource location allows the carrying resources of the communication parameters to be flexibly adjusted according to the feedback resources, making it suitable for scenarios with dynamically changing resources, such as UAV networks or satellite communications, ensuring accurate transmission of communication parameters and improving communication flexibility.

[0088] In one embodiment, determining the time-frequency resource location of the feedback resource based on the time-frequency resource location of the SSB and a first predefined rule includes: determining the time slot location of the feedback resource based on the SSB's reception processing time and time slot, wherein the time slot symbol position within the time slot is a predefined position; and determining the frequency domain range of the feedback resource based on the SSB's frequency domain range and the first predefined rule. This feedback resource determination method based on the SSB's time-frequency resource location and predefined rules simplifies the resource allocation algorithm and improves the efficiency of resource allocation.

[0089] Furthermore, if the feedback resource occupies K PRBs in the frequency domain, the frequency domain location of the feedback resource is one of the following: a predefined feedback resource location among all candidate feedback resources within the frequency domain range of the feedback resource; any feedback resource location among all candidate feedback resources within the frequency domain range of the feedback resource; or, within the frequency domain range of the feedback resource, the frequency domain resource location is determined based on at least one of the following: the control node ID carried in the SSB, the number of candidate feedback resources within the frequency domain range of the feedback resource, the number of RBs within the frequency domain range of the feedback resource, the member UE ID, the member UE group ID, and the service ID. The feedback resource occupies K physically contiguous PRBs and K logically contiguous PRBs. This method of determining the frequency domain resource location considers the influence of multiple factors, enabling more refined resource management. It is suitable for scenarios with diverse frequency domain resource requirements, such as virtual reality (VR) or augmented reality (AR) applications, ensuring that the frequency domain resource requirements of different applications are met.

[0090] In another embodiment, determining the time-frequency resource location of the feedback resource for receiving communication parameter request information using the time-frequency resource location of the SSB and a first predefined rule may specifically include: if there is only one feedback resource, determining the time-domain and frequency-domain resource locations of the feedback resource using the time-frequency resource location of the SSB and the first predefined rule; if there are multiple feedback resources, determining the time-domain and frequency-domain resource locations of the first feedback resource using the time-frequency resource location of the SSB and the first predefined rule, and determining the time-domain and frequency-domain resource locations of other feedback resources according to the predefined time-domain and frequency-domain intervals between feedback resources and the time-domain and frequency-domain resource locations of the first feedback resource, wherein the other feedback resources are the feedback resources other than the first feedback resource among the multiple feedback resources. This rule-based feedback resource determination method makes resource allocation more orderly and predictable, and is suitable for network planning and optimization scenarios, such as network capacity planning or network performance optimization, effectively avoiding resource conflicts and improving the overall network performance.

[0091] Furthermore, determining the time-frequency resource location carrying communication parameters through the time-frequency resource location of the SSB and a second predefined rule includes: determining multiple candidate resource locations of the target channel carrying communication parameters within the resource window based on the time-frequency resource range of the SSB, wherein the target channel is one of the following: a data channel carrying communication parameters, a control channel carrying communication parameters, or a control channel corresponding to the data channel carrying communication parameters; or determining the time-frequency resource location of the target channel carrying communication parameters based on the reference time-domain resource location, reference frequency-domain resource location, predefined time-domain size, and predefined frequency-domain size determined by the time-frequency resource location of the SSB, wherein the target channel is one of the following: a data channel carrying communication parameters, a control channel carrying communication parameters, or a control channel corresponding to the data channel carrying communication parameters. This rule-based method for determining the carrier resource ensures reliable transmission of communication parameters and is suitable for scenarios with high reliability requirements, such as industrial automation or telemedicine, ensuring the accuracy and timeliness of data transmission and improving the communication quality of critical services.

[0092] Further, determining multiple candidate resource positions of the target channel carrying communication parameters within the resource window based on the time-frequency resource range of the SSB can specifically include: obtaining the starting time-domain position M and the ending time-domain position N, the starting frequency-domain position P and the ending frequency-domain position Q of the resource window, where the time-domain resource size of the target channel is a and the frequency-domain resource size is b; determining the starting time-domain positions of the candidate resource positions as M, M+a-1, M+2a-1, ..., M+na-1, and determining the starting frequency-domain positions of the candidate resource positions as P, P+b-1, P+2b-1, ..., P+mb-1, where M+na-1 is less than or equal to N, P+mb-1 is less than or equal to Q, and m and n are non-negative integers; or determining the starting time-domain positions of the candidate resource positions as M, M+1, M+2, ..., N-a+1, and determining the starting frequency-domain positions of the candidate resource positions as P, P+1, P+2, ..., Q-b+1.

[0093] The communication parameter receiving method of this disclosure is not only applicable to traditional cellular networks, but also to future scenarios such as connected vehicles, smart homes, and smart cities. Through SSB indication and predefined rules, member UEs can automatically and quickly determine the resources for feedback and carrying communication parameters, reducing network control signaling overhead and improving network flexibility and communication efficiency. In multi-UE or multi-service scenarios, this method can effectively distinguish and manage the feedback and parameter transmission of different UEs or services, enhancing the system's scalability and adaptability, and providing technical assurance for the efficient operation of future networks. Furthermore, this method also considers the determination of resource windows and candidate resource locations, enabling dynamic adjustment of resource allocation strategies according to actual network needs, ensuring reliable transmission of communication parameters, improving user experience and network performance, and laying the foundation for building a more intelligent, efficient, and reliable future network.

[0094] Figure 7 is a schematic diagram of information interaction between the control node UE and member UE according to an embodiment of the present disclosure. As shown in Figure 7, the time-frequency resource location of the feedback resource PSFCH (Physical sidelink feedback channel) is indicated in the SSB transmitted by the control node UE. UEs that need to receive SL communication parameter messages feed back communication parameter request information on the feedback resource. After receiving the request information, the control node sends the communication parameter information corresponding to the communication parameter request information to the member UE. The communication parameter information is carried on the SL physical data sharing channel.

[0095] The UE that sends feedback information attempts to receive the communication parameter information. Furthermore, if the member UE fails to receive the communication parameter information, the member UE continues to send feedback communication parameter request information on the feedback resource indicated by the next SSB until it is received correctly.

[0096] Specifically, determining the location of PSFCH can include: explicitly indicating the time-frequency resource location of one or more PSFCH resources in the communication parameter information of the master information block in the SSB; or implicitly determining the time-frequency resource location of one or more PSFCHs based on the time-frequency resource location of the SSB and predefined parameters.

[0097] Furthermore, the determination of time-frequency resources for SL communication parameters may specifically include: the communication parameter information in the SSB explicitly indicating or implicitly determining the time-frequency resource location of the control information of the communication parameter information, and the communication parameter control information indicating the time-frequency resource location of the communication parameter data information; the communication parameter information in the SSB explicitly indicating or implicitly determining the time-frequency resource location of both the control information and data information of the communication parameter information; the communication parameter information in the SSB explicitly indicating or implicitly determining the time-frequency resource location of the data information of the communication parameter information; implicitly determining the time-frequency resource location of the control information of the communication parameter message based on the PSFCH resource location determined by the SSB and predefined parameters; and implicitly determining the time-frequency resource location of the data information of the communication parameter message based on the PSFCH resource location determined by the SSB and predefined parameters.

[0098] The following section provides a detailed explanation of how to determine the feedback resource PSFCH (Physical Side Link Feedback Channel) using specific examples.

[0099] In an exemplary embodiment, the SSB explicitly indicates the location of the PSFCH resource. Figure 8 is a schematic diagram of PSBCH channel indication according to an embodiment of the present disclosure. As shown in Figure 8, the PSBCH channel of the SSB explicitly indicates, specifically, the following:

[0100] Slot position: Explicitly indicates the slot index of the PSFCH slot relative to the SSB. The symbol position within the slot is one or more predefined positions. The time domain duration of the PSFCH is a predefined length.

[0101] Frequency domain resource location: Explicitly indicates the relative displacement of the starting frequency domain location of the PSFCH with respect to a reference frequency domain of the SSB. The frequency domain size of the PSFCH is a predefined setting.

[0102] Alternatively, the time-domain indication method can be to directly indicate the slot index of the PSFCH slot relative to the SSB and the symbol position within the slot.

[0103] In another exemplary embodiment, the SSB explicitly indicates the location of the PSFCH resource. Figure 9 is a second schematic diagram of PSBCH channel indication according to an embodiment of the present disclosure. As shown in Figure 9, the PSBCH channel of the SSB explicitly indicates, specifically, the following:

[0104] Time slot location: Assuming the SSB's reception processing time is K time slots and the SSB is located in time slot n, then the PSFCH is located in time slot n+K+1.

[0105] Symbol position within a time slot: SSB indicates the offset of the starting symbol of the PSFCH resource within the PSFCH time slot relative to the symbol of that time slot.

[0106] Frequency domain resource location: Explicitly indicates the relative displacement of the starting frequency domain location of the PSFCH with respect to a reference frequency domain of the SSB. The frequency domain size of the PSFCH is a predefined setting.

[0107] In another exemplary embodiment, the resource location of the PSFCH is implicitly determined, specifically including:

[0108] Time slot location: Assuming the SSB's reception processing time is K time slots and the SSB is located in time slot n, then the PSFCH is located in time slot n+K+1.

[0109] Location of time-frequency resources within a time slot:

[0110] Symbol position within a time slot: the predetermined position;

[0111] Frequency domain location: The frequency domain range of the PSFCH is determined based on the frequency domain range of the SSB. One example is that the frequency domain range of the PSFCH is the same as that of the SSB. Assuming that the PSFCH occupies 1 PRB in the frequency domain, the frequency domain location of the PSFCH can be one of the following:

[0112] Predefined positions within the PSFCH frequency domain;

[0113] Any random position within the PSFCH frequency domain;

[0114] Within the PSFCH frequency domain, the PRB whose ID of the control node UE carried in the SSB is modulo the number of resources in the PSFCH frequency domain is used as the starting PRB of the PSFCH.

[0115] Within the PSFCH frequency domain, the resource whose ID of the control node UE carried in the SSB is modulo the number of RBs in the PSFCH frequency domain is taken as the frequency domain resource location of the PSFCH.

[0116] For Examples 1 to 3 above, one or more PSFCH resources can be implicitly or explicitly determined by at least one of the three methods above. If there are multiple PSFCH resources, the location of the first PSFCH resource is determined first by the above method, and then the locations of the remaining PSFCH resources are determined according to the predefined time-domain interval and frequency-domain interval between PSFCH resources.

[0117] Figure 10 is a schematic diagram of multiple PSFCH resources according to an embodiment of the present disclosure. As shown in Figure 10, if multiple PSFCH resources are determined by SSB, PSFCH resources at different locations can correspond to different SL communication parameter information requests; or PSFCH resources at different locations can correspond to communication parameter message request resources of different types of UEs; or PSFCH resources at different locations can correspond to different SL communication parameter information of different types of UEs.

[0118] The determination of communication parameter resource locations will be explained in detail below with specific examples.

[0119] In one exemplary embodiment, the location of communication parameter resources is explicitly indicated. The communication parameter information at the physical layer only includes the data channel, and the time-frequency resource location information of the data channel carrying the communication parameter information is explicitly indicated in the broadcast channel of the SSB.

[0120] Figure 11 is a schematic diagram of the location of communication parameter resources according to an embodiment of the present disclosure. As shown in Figure 11, the relative time slot index and the relative frequency domain index within the time slot are indicated in the SSB broadcast channel.

[0121] The relative slot index of the communication parameter data is indicated relative to the slot n of the SSB;

[0122] The relative frequency domain index within a time slot is indicated relative to a certain frequency domain position of the SSB (the first PRB of the SSB);

[0123] The duration of the communication parameters in the time domain is a predefined length, and the duration in the frequency domain is also a predefined length.

[0124] In another exemplary embodiment, a transmission time window for communication parameter messages is predefined. Assuming the window length is m time slots and the time slot where PSFCH is located is time slot L, then the transmission time window for communication parameter messages is [L+1,L+m].

[0125] The frequency range of the communication parameter transmission is determined based on the frequency position of the SSB. For example, if the frequency range of the SSB is RBk to RBk+j-1 (a total of j PRBs), then the frequency position of the communication parameter is determined to be RBk to RBk+2*j-1 (a total of 2*j PRBs). Assuming the communication parameter message frequency domain requires P PRBs, then the frequency range of the communication parameter transmission can be determined as follows: Candidate resources for communication parameter messages, for the control node UE in each time slot within the time window [L+1,L+m]. One or more candidate resources for communication parameters are determined on the candidate resources for transmitting communication parameter messages, and the member UE blindly checks the communication parameter messages on these candidate resources.

[0126] When the physical layer only contains the data channel, the time-frequency resource location of the data channel carrying the communication parameter information can also be determined based on the reference time domain location, reference frequency domain location, predefined time domain size, and predefined frequency domain size determined by the time-frequency resource location information of the SSB.

[0127] Figure 12 is a second schematic diagram of indicating the location of communication parameter resources according to an embodiment of the present disclosure. As shown in Figure 12, the communication parameter information includes a control channel and a data channel at the physical layer. The time-frequency resource location information of the control channel carrying the communication parameter information is explicitly indicated in the broadcast channel of the SSB. The time-frequency resource location of the communication parameter information data channel is further determined based on the indicated control channel.

[0128] The communication parameter information at the physical layer includes control channels and data channels. The time-frequency resource location information of the control channel carrying the communication parameter information is determined based on the reference time domain location, reference frequency domain location, predefined time domain size, and predefined frequency domain size determined by the time-frequency resource location information of the SSB. Furthermore, the time-frequency resource location of the communication parameter information data channel is determined based on the determined control channel.

[0129] When the communication parameter message includes the control channel and the data channel of the communication parameters, the transmission time window of the communication parameter message is predefined. Assuming the window length is m time slots and the time slot where PSFCH is located is time slot L, then the transmission time window of the communication parameter message is [L+1,L+m].

[0130] The frequency domain range of the communication parameter control channel transmission is determined based on the frequency domain position of the SSB. For example, if the frequency domain range of the SSB is RBk to RBk+j-1 (a total of j PRBs), then the frequency domain position of the communication parameter is determined to be RBk to RBk+2*j-1 (a total of 2*j PRBs). Assuming the frequency domain of the communication parameter message control channel requires P' PRBs, then the frequency domain range of the communication parameter message control channel can be determined... Candidate resources for the control channel of a communication parameter message, for the control node UE in each time slot within the time window [L+1,L+m]. One or more candidate control channels for communication parameter messages are determined on the resources of the candidate control channels for transmitting communication parameter messages. The resources of the data channels for the further communication parameter messages are indicated in the control channels of the communication parameter messages.

[0131] Member UEs blindly check the communication parameter message control channel on these candidate control channel resources, and further determine the communication parameter messages carried in the communication parameter data channel.

[0132] The control node periodically sends SSB information, and implicitly or explicitly indicates a PSFCH resource in some or all of the SSBs. The control node receives the PSFCH. When it receives the feedback information, the control node sends the corresponding SL communication parameter information to the member UE on the communication parameter time-frequency resource that is implicitly determined or explicitly indicated.

[0133] Figure 13 is a schematic diagram of the control node UE periodically sending SSB according to an embodiment of the present disclosure. As shown in Figure 13, the control node periodically sends SSB information, and implicitly or explicitly indicates two PSFCH resources in some or all of the SSBs. The control node receives the information on the PSFCH. After receiving the feedback information on the two PSFCH resources respectively, the control node sends the corresponding SL communication parameter information to the member UE on the communication parameter time-frequency resources that are implicitly determined or explicitly indicated.

[0134] Figure 14 is a schematic diagram of a member UE periodically receiving an SSB according to an embodiment of the present disclosure. As shown in Figure 14, the member UE blindly detects the SSB of the control node, determines the resources and synchronization timing of the SSB, and further determines the PSFCH feedback resources. The member UE sends communication parameter request information on the corresponding PSFCH feedback resources and receives communication parameter information on the determined communication parameter resources.

[0135] The communication parameter information shall include at least one of the following: configuration information for discontinuous reception DRX, synchronization source information, clock information, communication carrier configuration information, communication BWP configuration information, communication resource pool configuration information, TDD-DL-UL pattern information, and channel measurement feedback information.

[0136] Multiple communication parameter messages for different purposes can be multiplexed on the physical transmission channel. These messages can correspond to the same UE or different UEs. The physical transmission channel for communication parameters can be unicast, multicast, or broadcast.

[0137] The control node UE periodically sends SSB information on the SL link. The SSB can indicate whether there is a communication parameter feedback resource PSFCH and a communication parameter message to be sent after this SSB.
