[0001] (Cross - reference to Related Applications) This disclosure is based on Chinese Patent Application CN202210591046.X, titled "System Information Transmission, Wireless Communication System Access Method and Apparatus", filed on May 27, 2022. This disclosure claims the priority of the said patent application, and its content is incorporated herein by reference in its entirety. (Technical Field) Embodiments of this disclosure relate to the field of communications. Specifically, they relate to system information transmission, wireless communication system access methods and apparatuses.

Background Art

[0002] The large-scale commercialization of the 5th Generation Mobile Communication System (5G) and New Radio (NR) is accelerating the transformation of the economy and society towards digitalization, networking, and intelligence, and is promoting networks to usher in a new era of the Internet of Everything (IoE). The rapidly emerging application needs in areas such as smart cities, smart transportation, and smart industrial production are continuously strengthening the development trends of differentiated network equipment capabilities, diversified network functions, and intelligent network management and control, further accelerating the arrival of the 6th Generation Mobile Communication System (6G), where everything is smartly connected. In a 5G NR system, system information is transmitted via the Physical Broadcast Channel (PBCH) in the Synchronization Signal / Physical Broadcast Channel Block (SSB) as a Master Information Block (MIB), and then via the Physical Downlink Shared Channel (PDSCH) as a System Information Block (SIB). Here, the SIB can be divided into multiple blocks, each carrying different system information.

[0003] Typical 6G application scenarios, such as smart cities, smart transportation, and smart homes, involve a large number of highly differentiated smart automation devices, leading to increasingly stringent communication requirements for extremely low latency, extremely high reliability, ultra-wide bandwidth, and massive access volume. Furthermore, smart automation applications demand high precision and high resolution in sensing capabilities. In other words, in the 6G era, the variety of terminals accessing the system will be enormous, and broadcasting system information using such MIB+SIB methods in NR will have a serious impact on the system's spectral efficiency and increase the burden on terminals. This is because different types of terminals require different levels and frequencies of system information, and the rapid increase in the number of wireless communications and sensing devices will exacerbate the contradiction between the unlimited growth of service demand and finite wireless resources and computing power. On the other hand, realizing the 6G vision requires closed-loop information flow processing from acquiring sensing information about the environment, interacting with and sharing information, and smart information processing to layer-by-layer distribution of control information (including control information for the communication network and control commands for application execution devices). Conventional wireless network architectures and related technologies are already struggling to meet the ongoing application needs of the Beyond 5G (5G and Beyond, B5G) / 6G era. There is an urgent need to develop new network architectures and enable technologies that efficiently utilize resources and differentiate the application of smart adapters, and to propose system information transmission methods tailored to the type of terminal. [Overview of the Initiative] [Problems that the invention aims to solve]

Embodiments for Carrying Out the Invention

[0012] Hereinafter, with reference to the drawings, embodiments of the present disclosure will be described in detail together with embodiments. In addition, terms such as "first", "second", etc. in the specification, claims, and above-mentioned drawings of the present disclosure are for distinguishing similar objects and do not necessarily need to explain a specific order or sequence.

[0013] Embodiments of the methods provided in the embodiments of this disclosure can be executed in a mobile second node, a computer second node, or a similar computing device. Taking execution in a mobile second node as an example, Figure 1 is a hardware structure block diagram of a mobile second node of the system information transmission method in an embodiment of this disclosure. As shown in Figure 1, the mobile second node may include one or more (only one is shown in Figure 1) processors 102 (the processors 102 may include, but are not limited to, processing devices such as a microprocessor MCU or a programmable logic circuit FPGA), and a memory 104 for storing data, wherein the mobile second node may further include transmission equipment 106 and input / output equipment 108 for communication functions. Those skilled in the art will understand that the structure shown in Figure 1 is illustrative and does not limit the structure of the mobile second node. For example, the mobile second node may further include more or fewer components than those shown in Figure 1, or may have a different configuration than that shown in Figure 1.

[0014] Memory 104 can be used to store computer programs such as application software and modules like computer programs corresponding to the system information transmission method of the embodiments of the present disclosure. The processor 102 executes the computer programs stored in the memory 104 to execute various functional applications and data processing, that is, to implement the above method. The memory 104 may include a 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 memories. In some examples, the memory 104 may further include a memory installed remotely with respect to the processor 102, and these remote memories can be connected to the mobile second node via a network. Examples of the above network include, but are not limited to, the Internet, intranet, local area network, mobile communication network, and combinations thereof.

[0015] The transmission device 106 is used to receive or transmit data via a network. Specific examples of the above network may include a wireless network provided by the communication provider of the mobile second node. In one example, the transmission device 106 includes a network adapter (abbreviated as NIC, Network Interface Controller) that can communicate with the Internet by connecting to other network devices via a base station. In one example, the transmission device 106 may be a radio frequency (RF) module for communicating with the Internet in a wireless manner.

[0016] The embodiments of this disclosure can be implemented using the system network architecture shown in Figure 2, which includes a terminal, a basic network, conventional network 1 (e.g., a 5G NR system), conventional network 2 (e.g., a 4G NB-IoT network), and two sets of user-centric custom networks (including user-centric network 1 and user-centric network 2), where the basic network supports multiple different types of networks (i.e., conventional network 1, conventional network 2, user-centric network 1, and user-centric network 2). First, the terminal accesses the basic network, and then the basic network selects a network that matches the accessed terminal according to information such as the terminal type, and then transmits system information according to a specific method.

[0017] This embodiment provides a system information transmission method that can be executed on the above-described mobile second node or system network architecture. Figure 3 is a flowchart of the system information transmission method according to the embodiment of this disclosure, and as shown in Figure 3, the flow is as follows: Step S302 divides the system information block of a wireless communication system that supports multiple different types of networks into a first set including a basic system information block and at least one second set including at least one of the system information blocks corresponding to at least one type of network and at least one system information block corresponding to a second node of at least one type. Step S304 includes the first node transmitting first system information, which includes at least one system information block in the second set, to the second node via a downlink channel.

[0018] The above steps divide the system information block of the wireless communication system into a first set and at least one second set, and the first node transmits the first system information to the second node via the downlink channel. Here, the wireless communication system supports multiple different types of networks and solves the problem of the lack of a system information transmission method tailored to the type of terminal, thereby achieving the effect of efficiently utilizing wireless communication system resources.

[0019] As a person skilled in the art will see, the entity performing the above steps may be, but is not limited to, a base station, a mobile second node, a terminal, etc.

[0020] As will be apparent to those skilled in the art, the first node and the second node involved in the above steps are both demonstrative nouns, where the first node may be a base station or network side, and the second node may be a terminal or other system or device capable of implementing the above method, and are not limited thereto.

[0021] As a person skilled in the art will see, the basic system information block relating to the above steps refers to system information necessary for different types of terminals (or mobile second nodes, etc.) to access the wireless communication system, where the network that follows the instructions of the basic system information block may also be called the basic network, and the basic network may be an existing type of network or a custom network, and the function of the basic network is to allow different types of terminals to access the wireless communication system first in order to subsequently receive system information blocks in the second set and assign them to different networks suitable for the terminal type.

[0022] In one exemplary embodiment, the multiple different types of networks may include at least one of existing networks and custom networks.

[0023] Here, when the first node searches for a network that matches the second node, it first searches the existing network. If the search fails, that is, if no network matching the second node is found in the existing network, the first node needs to construct a new network, i.e., a custom network that matches the second node. In the subsequent system information transmission process, when matching a new second node or third node, etc., with the network within the first node, the first node similarly searches the existing network. The existing network at this time includes the initial existing network and the custom network constructed thereafter. If none of these networks match the new second node, the first node needs to construct a new network.

[0024] Here, the existing network may be a network in which a 4G LTE network architecture, a 4G NB-IoT network architecture, a 4G MTC network architecture, a 5G NR network architecture, etc., is pre-configured / stored. The custom network may be a communication network built to meet the communication needs of one or more specific types of terminals, or it may be a communication network constructed by adjusting the configuration of an existing network based on a conventional network to meet the communication needs of one or more specific types of terminals.

[0025] The meaning of matching to the second node as described above may be matching to the type of the second node, or it may be matching to the network type required for the second node.

[0026] Here, the first system information relating to the above embodiment is obtained from a first system information block set, and the first system information block set is included in at least the system information blocks in the second set, and the first system information block set may further include the basic system information blocks in the first set. Furthermore, when the first system information block set is divided into one or more subsets, the first system information is at least one of those subsets. Furthermore, the method of dividing the first system information block set into subsets may be a method of dividing by information such as terminal type and service type requested by the terminal. Furthermore, the method of dividing the first system information block set into subsets may be a method by which the first node (which may be the network side) transmits to the second node (which may be the terminal), or a method by which it is stored in the second node (which may be the terminal) in the default configuration.

[0027] In one exemplary embodiment, the step of a first node of a wireless communication system transmitting first system information to a second node via a downlink channel includes, if a first condition is met, the first node transmitting first system information to the second node via a downlink channel.

[0028] Here, the first condition includes at least one of the following: the first node detects uplink information transmitted by the second node on an uplink channel; the first node detects that the detection result of the uplink information transmitted by the second node on an uplink channel is greater than or equal to a threshold; and the first node receives first system information transmission request information from the second node.

[0029] In one exemplary embodiment, the first node of the wireless communication system transmits at least one of the following to the second node via the downlink channel: the transmission start time, transmission period, and transmission frequency of the first system information.

[0030] Here, the transmission start time, transmission cycle, and transmission frequency of the first system information may be transmitted to the second node simultaneously with the first system information, or the transmission start time, transmission cycle, and transmission frequency of the first system information may be transmitted after the transmission of the first system information is completed. Furthermore, as will be apparent to those skilled in the art, the downlink channel for transmitting the transmission start time, transmission cycle, and transmission frequency of the first system information and the downlink channel for transmitting the first system information may be the same downlink channel or different downlink channels, and are not limited thereto.

[0031] In one exemplary embodiment, a first node of a wireless communication system transmits first system information to a second node via a downlink channel, and further includes the step of the first node receiving uplink information transmitted by the second node via an uplink channel if the second node satisfies a second condition, the second condition including at least one of the following: the second node failed to receive first system information matching it; the second node failed to receive first system information matching it transmitted by the first node within a specified period after transmitting uplink information; the second node received a basic system information block in a first set, and the basic system information block does not indicate transmission resource configuration information corresponding to first system information matching it; the second node enters a connected state from an idle state; and the update time for the system resource block of the second node arrives. Figure 4 is a flowchart of a system information transmission method according to an embodiment of the present disclosure, and as shown in Figure 4, the flow includes, Step S402 divides the system information block of a wireless communication system that supports multiple different types of networks into a first set containing basic system information blocks and at least one second set containing system information blocks, Step S404, in which the first node of the wireless communication system transmits first system information, including at least one system information block in the second set, to the second node via a downlink channel, The procedure includes step S406, in which the first node receives uplink information transmitted by the second node via an uplink channel if the second node satisfies a second condition.

[0032] In one exemplary embodiment, after the second node accesses the wireless communication system in accordance with the basic system information block of the first set, the first node receives the first information reported by the second node. Furthermore, the first node receiving the first information reported by the second node occurs before the first node transmits the first system information to the second node via the downlink channel.

[0033] In one exemplary embodiment, after the first node receives first information reported by the second node, the first node further searches for a network matching the second node from a plurality of different types of networks according to the first information, if a network matching the second node is found, transmits the configuration information of the network to the second node via the first system information, and if no network matching the second node is found, the first node constructs a custom network matching the second node. Figure 5 is a flowchart of a system information transmission method according to an embodiment of the present disclosure, and as shown in Figure 5, the flow includes, Step S502, in which the second node accesses the wireless communication system according to the basic system information block of the first set, Step S504, in which the first node receives first information reported by the second node, The first node searches for a network matching the second node from the plurality of different types of networks according to the first information, and if a network matching the second node is found, transmits the configuration information of the network to the second node, and if no network matching the second node is found, the first node constructs a custom network matching the second node, the step S506.

[0034] In one exemplary embodiment, the first information includes at least one of the following: the service type required by the second node, the functionality of the second node that requires support from the first node, hardware configuration information of the second node, the coding and decoding scheme required by the second node, the receiver detection algorithm required by the second node, and the communication protocol version information supported by the second node.

[0035] In one exemplary embodiment, before the first node constructs a custom network that matches the second node, the first node further includes the steps of: transmitting second information to the second node in a first system which is a network indicated according to the basic system information block of the first set; and the first node receiving response information from the second node to the second information. Figure 6 is a flowchart of the construction of a custom network according to an embodiment of the present disclosure, and as shown in Figure 6, the flow is as follows: Step S602, in which the first node does not search for a network matching the second node from multiple different types of networks according to the first information, Step S604, in which the first node transmits second information to the second node in a first system which is a network instructed according to the basic system information block of the first set, The first node receives response information from the second node for the second information, S606, and the process includes these steps.

[0036] In one exemplary embodiment, the second information includes at least one of the following: instruction information for the custom network construction, latency information for the custom network construction, and payment information for the custom network construction.

[0037] Another embodiment of the present disclosure provides a wireless communication system access method that can be performed on the above-described mobile second node or system network architecture, where Figure 7 is a flowchart of the wireless communication system access method according to an embodiment of the present disclosure, and as shown in Figure 7, the flow is as follows: Step S702, in which the first subnode of the wireless communication system receives third information transmitted by the second subnode, The process includes step S704, in which the first subnode detects the third information and, if the third condition is met, the first subnode establishes a connection with the second subnode.

[0038] In one exemplary embodiment, the third information includes at least one of whether the second subnode allows other subnodes to establish a connection with it, and whether the second subnode accesses the wireless communication system.

[0039] In one exemplary embodiment, the third condition includes at least one of the following: the detection result of the third information is greater than or equal to a threshold; and the second subnode has accessed the wireless communication system.

[0040] In one exemplary embodiment, after a first subnode of a wireless communication system receives third information transmitted by a second subnode, the first subnode further detects the third information and, if a fourth condition is met, receives fourth information transmitted by the second subnode. Figure 8 is a flowchart of a wireless communication system access method according to an embodiment of the present disclosure, and as shown in Figure 8, the flow is as follows: Step S802, in which the first subnode of the wireless communication system receives third information transmitted by the second subnode, Step S804, in which the first subnode detects the third information and satisfies the third condition, the first subnode establishes a connection with the second subnode, The process includes step S806, in which the first subnode detects the third information and, if the fourth condition is met, the first subnode receives the fourth information transmitted by the second subnode.

[0041] In one exemplary embodiment, the fourth condition includes at least one of the following: the identity information of the first subnode is authenticated and / or authorized and / or registered by the wireless communication system; and the wireless communication system permits the second subnode to transmit some or all of the system information of the wireless communication system on behalf of the first subnode.

Figure 9 is a flowchart of a wireless communication system access method according to an embodiment of the present disclosure, and as shown in Figure 9, the flow is as follows: Step S902, in which the first subnode of the wireless communication system receives third information transmitted by the second subnode, Step S904, in which the first subnode detects the third information and satisfies the third condition, the first subnode establishes a connection with the second subnode, Step S906, if the first subnode detects the third information and satisfies the fourth condition, the first subnode receives the fourth information transmitted by the second subnode. The process includes step S908, in which the first subnode initiates a random access flow in accordance with the fourth information.

[0044] In one exemplary embodiment, the first subnode receives fourth information transmitted by the second subnode, and then the first subnode further receives fifth information transmitted by the second subnode, and the first subnode transmits uplink information in accordance with the fifth information.

Thus, the disclosure is not limited to any particular combination of hardware and software.

[0064] To enable those skilled in the art to better understand the technical solutions of this disclosure, specific scenario examples are described below.

[0065] In a 5G NR system, SSB can be transmitted using a multi-beam method, meaning that SSB information can be transmitted in different beam directions, allowing a terminal to receive the TRP (Transmit-Receive Point, a new term for 5G base stations) synchronization signal / physical broadcast channel block (SSB). Here, SSB includes the primary synchronization signal (PSS), the secondary synchronization signal (SSS), and the physical broadcast channel (PBCH).

[0066] In the scene embodiment of this disclosure, in order to clearly illustrate the technical solution, the first node of the above embodiment is replaced on the network side (base station), the second node is replaced at the terminal, the first subnode is replaced with a first type terminal, and the second subnode is replaced with a second type terminal. As those skilled in the art will see, this is merely one embodiment and does not specifically limit the methods and apparatus related to the above embodiment. In the process of actually operating and implementing the above, the actual entity of the node may be any system or apparatus capable of realizing the execution of the above method.

[0067] (Scene Example 1) Figure 15 is a flowchart of a user-type based network architecture configuration method according to a scene embodiment of this disclosure, and as shown in Figure 15, the flow is as follows: Step 1502: The network side transmits first system configuration information, or the configuration information of the first system is stored on the terminal and network sides in a standard default configuration. Step 1504 completes reporting to the network side first information, which includes, after the terminal accesses the first system according to the first system configuration information, the service type required by the terminal (including access time delay requirements, peak rate requirements, average rate requirements, etc.), terminal functions that require support from the network side, terminal hardware configuration information (including maximum transmit power requirements, antenna configuration information, etc.), encoding and decoding methods required by the terminal, receiver detection algorithms required by the terminal, and (wireless and / or wired) communication protocol version information supported by the terminal. Step 1506, after the network side receives the first information, completes the selection of a system to be assigned to the terminal, following the principles that (1) first, the network side finds a conventional architecture / system that matches the first information of the UE from the conventional architecture / systems it supports, and transmits the configuration information of the corresponding conventional architecture / system to the terminal, and (2) if there is no conventional architecture / system that meets the terminal's needs, a new architecture / system must be built to support the terminal's needs. Step 1508, in which the network side needs to transmit second information to the terminal in the first system when it is necessary to build a new architecture / system to support the terminal's needs, the second information is (1) Instructions for a new architecture / system, (2) Latency delay information for new architectures / systems, (3) Step 1508, which includes at least one of the payment information for the new architecture / system, The process includes step 1510, in which the network side, after receiving confirmation information for the terminal's second information, constructs a new architecture / system and transmits the configuration information of the new architecture / system to the terminal.

[0068] The steps outlined above will be described below, along with specific implementation plans. A single wireless system has one basic network and a large number of different types of terminals. The types of terminals in this embodiment include a first type terminal (high data transmission rate requirements, low transmission delay requirements), a second type terminal (low data transmission rate requirements, high transmission delay requirements), and a third type terminal (ultra-high data transmission rate requirements, ultra-low transmission delay requirements, 24-hour continuous service guarantee). These three types of terminals first connect to the system via the basic network in the system and transmit their needs to the network side.

[0069] The network side assigns terminals to the network that best matches their needs, according to their requirements. As shown in the diagram below, this system includes conventional network 1 (e.g., a 5G NR system), conventional network 2 (a 4G NB-IoT network), and two sets of custom networks centered around users.

[0070] Type 1 terminals (high data transmission rate requirements, low transmission delay requirements) are assigned to the 5G NR system. The network side transmits configuration information for the 5G NR system to the Type 1 terminals via the basic network. After receiving the configuration information for the 5G NR system, the Type 1 terminals attempt to access the 5G NR system.

[0071] The second type of terminal (with low data transmission rate requirements and high transmission delay requirements) is assigned to the 4G NB-IoT system. The network side transmits the configuration information of the 4G NB-IoT system to the second type of terminal via the basic network. After the second type of terminal receives the configuration information of the 4G NB-IoT system, it attempts to access the 4G NB-IoT system.

[0072] For a third type of terminal (requiring ultra-high data transmission rate, ultra-low transmission delay, and 24-hour service guarantee), if the system does not have a network capable of supporting the needs of the third type of terminal, the system sends custom network request information to the third type of terminal, and this custom network request information also includes custom network latency information and custom network cost information. After the third type of terminal confirms the custom network request information sent by the system, the system sends system configuration information for the custom network to the third type of terminal, and after the third type of terminal receives the system configuration information, it attempts to access the system.

[0073] (Scene Example 2) Figure 16 is a flowchart of a system information transmission method according to a scene embodiment of the present disclosure, and as shown in Figure 16, the method includes steps 1602 to 1606.

[0074] In step 1602, multiple system information blocks in the wireless communication system are divided into at least two sets.

[0075] In a wireless communication system, system information consists of a plurality of system information blocks, and these plurality of system information blocks are divided into at least two sets, and the system information blocks in set 1 (i.e., basic system information blocks, which include some shared configuration information in the system) are transmitted periodically, and the transmission period is configured by the network side or a default configuration is used. System information blocks in the other set (e.g., system information specific to a different type of terminal) are transmitted using a transmission method in which the network side transmits first system information to the terminal via the downlink channel if the first condition is met, where the first condition is: The network side detected the uplink information transmitted by the terminal on the uplink channel. The network side detects whether the detection result corresponding to the uplink information transmitted by the terminal on the uplink channel is above a threshold, and the detection result includes the Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indicator (RSSI), Signal to Noise Ratio (SNR), etc. This includes at least one of the following: the network side receiving first system information transmission request information sent by the terminal.

[0076] Here, the first system information is obtained from a first system information block set, where the first system information block set is obtained from at least the system information blocks of the other sets, where the first system information block set may further include the system information blocks of set 1. Furthermore, when the first system information block set is divided into one or more subsets, the first system information is at least one of those subsets. Furthermore, the method of dividing the first system information block set into subsets may be a method of division based on information such as terminal type and service type requested by the terminal. Furthermore, the method of dividing the first system information block set into subsets may be transmitted to the terminal by the network side, or it may be stored in the terminal using a default configuration.

[0077] Here, a mapping relationship exists between an uplink channel resource (an uplink channel resource includes at least a time-frequency resource, and if the uplink information transmitted on the uplink channel is a reference sequence, the uplink channel resource further includes reference sequence information) and a subset of a first system information block set, namely, M (where M is 1 or more) subsets of the first system information block set can constitute N (where N is 1 or more) sets of uplink channel resources, meaning that any terminal requesting these M subsets of the first system information block set can transmit over the N sets of uplink channel resources.

[0078] Here, a mapping relationship exists between the downlink channel resources and the subsets of the first system information block set, namely, M (where M is 1 or more) subsets of the first system information block set can constitute K (where K is 1 or more) sets of downlink channel resources, meaning that any terminal requesting these M subsets of the first system information block set can receive the corresponding first system information on the K sets of downlink channel resources.

[0079] In step 1604, the start time, transmission period, and transmission frequency of the first system information transmission are similarly transmitted by the network side via the downlink channel.

[0080] In step 1606, if the second condition is met, the terminal transmits uplink information on the uplink channel resource. The second condition is: The device was unable to receive the system information required for this device type. The terminal failed to receive the necessary system information transmitted by the network within one time window after the terminal transmitted uplink information on the uplink channel, and the length of the time window may be configured by the network or set by default, and the start position of the time window may be after the terminal has finished transmitting uplink information and after one time interval has passed, and the time interval may be set by the network or set by default. After the terminal receives the system information block in set 1, the resource configuration information that specifies the system information required for the terminal type is not present in the system information block in set 1. The device transitions from an idle state (RRC_IDLE mode) to a connected state (RRC_CONNECTED mode). This includes at least one of the following: the terminal system update time arrives (also known as the system update timer timeout, i.e., the time when the network side needs to send system information).

[0081] The steps outlined above will be explained below, along with specific implementation plans. In this implementation plan, the downlink channel in step 1602 is Msg2 during random access. The uplink channel is Msg1 during random access.

[0082] In this proposed implementation, a mapping relationship exists between random access resources (random access channel (PRACH) time-frequency resources and random access sequence (preamble) resources) and the system information block sets required by different types of terminals. A terminal selects the corresponding PRACH resource and preamble according to the system information block set required by its type. The terminal then transmits a random access signal. After receiving the random access signal, the network carries the system information required by the terminal in Msg2. Here, the system information includes at least the system bandwidth, system operating frequency, and the subcarrier spacing used by the system.

[0083] (Scene Example 3) Figure 17 is a flowchart of a method for accessing a terminal support system according to a scene embodiment of the present disclosure, and as shown in Figure 17, the method includes steps 1702 to 1708.

[0084] In step 1702, the first terminal detects first information transmitted by the second terminal, wherein the first information includes at least one of the following: that another terminal has detected the presence of the second terminal; whether the second terminal permits the other terminal to establish a connection with it; and whether the second terminal has already accessed the wireless communication system.

[0085] In step 1704, if the first terminal has detected the first information and the first condition is met, the first terminal establishes a connection with the second terminal. Here, the first condition is: At least one of the following is true: the RSRP / RSRQ / RSSI / SNR obtained by detecting the first information is greater than or equal to a threshold set by the first terminal, and the second terminal is a terminal that has already accessed the wireless communication system.

[0086] In step 1706, if the second condition is met, the second terminal transmits the second information to the first type terminal. Hereinafter, the second condition includes that the identity information of the first terminal has already been authenticated / authorized by the wireless communication system, and that the wireless communication system permits the second terminal to transmit some or all of the system information of the wireless communication system to the first terminal.

[0087] Here, the second information includes some or all system information of the wireless communication system accessed by the second terminal, timing advance information of the second terminal in the wireless communication system, distance information from the second terminal to the TRP, transmission power information of the second terminal, and identity authentication information of the second terminal in the wireless communication system.

[0088] In step 1708, after receiving the second information, the first terminal transmits a random access signal in the random access channel resource indicated by the system information therein to initiate a random access flow.

[0089] (Scene Example 4) Figure 18 is a flowchart of a method for accessing a terminal support system according to a scene embodiment of the present disclosure, and as shown in Figure 18, the method includes steps 1802 to 1810.

[0090] Steps 1802-1806, like steps 1702-1706, will not be explained in detail here.

[0091] In step 1808, the second terminal transmits third information to the first type terminal. The third information includes at least one of uplink data channel scheduling information and non-conflicting random access channel configuration information.

[0092] In step 1810, if the third information is scheduling information for an uplink data channel, the first terminal transmits uplink data to the TRP according to the resources indicated in the scheduling information. Here, the uplink data includes establishing a connection for the request information, and, if the third information is non-conflicting random access channel configuration information, the first terminal initiating a non-conflicting random access flow according to the resources indicated in the non-conflicting random access channel configuration information.
