Description

Technical Field

[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 hereby incorporated by reference in its entirety into this disclosure. (Technical Field) Embodiments of this disclosure relate to the field of communications, specifically to system information transmission, wireless communication system access methods and apparatuses.

Background Art

[0002] With the large-scale commercialization of the 5th Generation Mobile Communication System (5G) and New Radio (NR), the transformation towards the digitalization, networking, and intelligentization of the economic society has been accelerated, promoting the network into a new era of the Internet of Everything (IoE) where all things are connected to the Internet. Due to the application needs in aspects such as the rapidly emerging smart cities, smart transportation, and smart industrial production, the development trends of the differentiation of network device capabilities, the diversification of network functions, and the intelligentization of network management and control are continuously strengthened, further promoting the arrival of the 6th Generation Mobile Communication System (6G) where all things are smartly connected. In the 5G NR system, system information transmits the Master Information Block (MIB) via the Physical Broadcast Channel (PBCH) in the Synchronization Signal / Physical Broadcast Channel Block (SSB), and then conveys the System Information Block (SIB) via the Physical Downlink Shared Channel (PDSCH). Here, the SIB can be divided into multiple blocks that carry different system information respectively.

[0003] In typical application scenarios of 6G, such as smart cities, smart transportation, and smart homes, there are a large number of smart automation devices with highly differentiated capabilities, and the communication requirements for extremely low latency, extremely high reliability, ultra-wide bandwidth, a huge amount of access, etc. become more stringent. Due to the application of the smart automation type, requirements for sensing capabilities, such as high precision and high resolution, are also demanded. That is to say, in the 6G era, the types of terminals accessing the system will be extremely numerous. Using the MIB+SIB method like NR to broadcast system information will not only seriously affect the spectral efficiency of the system but also increase the burden on the terminals. This is because the details and frequencies of system information required by different types of terminals are different. With the rapid increase in the number of wireless communication and sensing devices, the contradiction between the infinite growth of service demand and the limited wireless resources and computing capabilities becomes increasingly prominent. On the other hand, the realization of the 6G vision requires closed-loop information flow processing from the acquisition of sensing information about the environment, information interaction and sharing, smart information processing to the layer-by-layer distribution of control information (including control information for communication networks and control commands for application execution devices). Conventional wireless network architectures and related technologies already have difficulty meeting the application needs that continue to occur in the Beyond5G (5G and Beyond, B5G) / 6G era. It is urgent to develop new network architectures and enabling technologies that can efficiently utilize resources and have differentiated applications of smart adapters, and it is necessary to propose a system information transmission method adapted to the type of terminal.

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 examples. Note that 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] Examples of the method provided in the embodiments of the present disclosure can be executed in a mobile second node, a computer second node, or a similar computing device. Taking the execution in the mobile second node as an example, FIG. 1 is a hardware structure block diagram of the mobile second node of the system information transmission method in the embodiments of the present disclosure. As shown in FIG. 1, the mobile second node may include one or more (only one is shown in FIG. 1) processors 102 (the processor 102 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic circuit FPGA), and a memory 104 for storing data. Here, the above-mentioned mobile second node may further include a transmission device 106 and an input / output device 108 for communication functions. Those skilled in the art will understand that the structure shown in FIG. 1 is merely exemplary and does not limit the structure of the above-mentioned mobile second node. For example, the mobile second node may further include more or fewer components than those shown in FIG. 1, or may have a different configuration from that shown in FIG. 1.

[0014] The 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 memories, 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 a communication provider of the mobile second node. In one example, the transmission device 106 includes a network interface controller (abbreviated as NIC) 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] Embodiments of the present disclosure can be implemented in the system network architecture shown in FIG. 2. As shown in FIG. 2, the system network architecture includes a terminal, a basic network, a conventional network 1 (e.g., a 5G NR system), a conventional network 2 (e.g., a 4G NB-IoT network), and a custom network centered around two sets of users (including a user-centered network 1 and a user-centered network 2). Here, the basic network supports a plurality of different types of networks (i.e., the conventional network 1, the conventional network 2, the user-centered network 1, and the user-centered 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 in a specific manner.

[0017] In this embodiment, a system information transmission method that can be executed by the above mobile second node or system network architecture is provided. FIG. 3 is a flowchart of the system information transmission method according to an embodiment of the present disclosure. As shown in FIG. 3, the flow includes: Step S302 of dividing the system information block of a wireless communication system that supports a plurality of different types of networks into a first set including a basic system information block and at least one second set including at least one system information block corresponding to at least one type of the network and at least one system information block corresponding to at least one type of the second node; Step S304 of the first node transmitting first system information including at least one system information block in the second set to the second node via a downlink channel.

[0018] By the above steps, the system information block of the wireless communication system is divided 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 a plurality of different types of networks, solving the problem of the related art that there is no system information transmission method adapted to the type of terminal, and achieving the effect of efficiently utilizing the resources of the wireless communication system.

[0019] As those skilled in the art will understand, the execution subject of the above steps may be, but is not limited to, a base station, a mobile second node, a terminal, etc.

[0020] As those skilled in the art will understand, the first node and the second node involved in the above steps are both indicative nouns. Here, the first node may be a base station or a network side, etc., and the second node may be a terminal or a system or device that can implement the execution of the other method, etc., and is not limited here.

[0021] As those skilled in the art will understand, the basic system information block involved in the above steps refers to the system information necessary for different types of terminals (or mobile second nodes, etc.) to access the wireless communication system. Here, the network following the instruction of the basic system information block may also be called a basic network. The basic network may be an existing type of network or a custom network. The function of the basic network is to first allow different types of terminals to access the wireless communication system in order to receive the system information blocks within the second set subsequently and allocate them to different networks suitable for the terminal type.

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

[0023] Here, when the first node searches for a network that matches the second node, it first searches in the existing network. If the search fails, that is, if a network that matches the second node cannot be found in the existing network, the first node needs to construct a new network, that is, a custom network that matches the second node. In the subsequent system information transmission process, when matching a new second node or a third node, etc. with the network in the first node, the first node similarly searches in the existing network. The existing network at this time includes the initial existing network and the custom network constructed later. If there is no network that matches the new second node in any of these networks, 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. are pre-configured / stored. The custom network may be a communication network constructed to meet the communication needs of one or more specific types of terminals, or it may be a communication network configured by adjusting the configuration of the existing network based on a conventional type of network to meet the communication needs of one or more specific types of terminals.

[0025] The meaning of matching the above-mentioned second node may be to match the type of the second node, or it may be to match the network type required by the second node.

[0026] Here, the first system information related to the above embodiments is obtained from a set of first system information blocks, and the set of first system information blocks includes at least the system information blocks within the second set. The set of first system information blocks may further include the basic system information blocks within the first set. Furthermore, when the set of first system information blocks is divided into one or more subsets, the first system information is at least one of the subsets. Furthermore, the division method of the set of first system information blocks into subsets may be a method of dividing according to information such as terminal type and service type applied for by the terminal. Furthermore, the division method of the set of first system information blocks into subsets may be a method in which the first node (which may be on the network side) transmits to the second node (which may be a terminal), or a method of being stored in the second node (which may be a terminal) in the default configuration.

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

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

[0030] Here, these pieces of information such as the transmission start time, transmission period, and transmission frequency of the first system information may be transmitted to the second node simultaneously with the first system information, or after the transmission of the first system information is completed, the transmission start time, transmission period, and transmission frequency of the first system information may be transmitted. Further, as will be understood by those skilled in the art, the downlink channel for transmitting the transmission start time, transmission period, 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 this is not limited herein.

[0031] In an exemplary embodiment, after a first node of a wireless communication system transmits first system information to a second node via a downlink channel, further, the first node receives, via an uplink channel, uplink information transmitted by the second node when the second node satisfies a second condition, where the second condition includes at least one of the following: the second node fails to receive first system information that matches the second node; after the second node transmits uplink information, the second node fails to receive, within a determined period, first system information transmitted by the first node that matches the second node; after the second node receives a basic system information block within a first set, the basic system information block does not indicate transmission resource configuration information corresponding to the first system information that matches the second node; the second node transitions from an idle state to a connected state; and the update time of the system resource block of the second node arrives.

And 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.

[0064] In order for those skilled in the art to better understand the technical solutions of the present disclosure, specific scenario embodiments are described below in combination.

[0065] In the 5G NR system, since the SSB can be transmitted in a multi-beam manner, that is, the SSB information can be transmitted in different beam directions, the terminal receives the Transmit-Receive Point (TRP, a new name for the 5G base station) Synchronization Signal / Physical Broadcast Channel Block (SSB). Here, the SSB includes a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH).

[0067] (Scene Embodiment 1) FIG. 15 is a flowchart of a network architecture configuration method based on user types according to the scene embodiment of the present disclosure. As shown in FIG. 15, the flow includes Step 1502 where the network side transmits the first system configuration information or stores the configuration information of the first system in the terminal and the network side according to the standard default configuration, After the terminal accesses the first system according to the first system configuration information, at least one of the service types required by the terminal (including access time delay requirements, peak rate requirements, average rate requirements, etc.), the functions of the terminal that require network support, the hardware configuration information of the terminal (including maximum transmission power requirements, antenna configuration information, etc.), the encoding and decoding methods required by the terminal, the receiver detection algorithm required by the terminal, and the (wireless and / or wired) communication protocol version information supported by the terminal. Step 1504 of completing the report of the first information to the network side; After the network side receives the first information, (1) First, the network side finds a conventional architecture / system that matches the first information of the UE from the conventional architectures / systems supported by the network side, and transmits the configuration information of the corresponding conventional architecture / system to the terminal. (2) If there is no conventional architecture / system that can meet the needs of the terminal, it is necessary to build a new architecture / system to support the needs of the terminal. According to the principle, step 1506 of completing the selection of the system assigned to the terminal; If it is necessary to build a new architecture / system to support the needs of the terminal, step 1508 in which the network side needs to transmit the second information to the terminal in the first system, and the second information includes: (1) Instruction information indicating the need for a new architecture / system; (2) Waiting time delay information of the new architecture / system; (3) Step 1508 including at least one of the payment information of the new architecture / system; After the network side receives the confirmation information for the second information of the terminal, build a new architecture / system and transmit the configuration information of the new architecture / system to the terminal. Step 1510;

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

[0069] According to the needs of the terminal, the network side assigns it to a network that matches its needs. As shown in the following figure, this system includes a conventional network 1 (such as a 5G NR system), a conventional network 2 (a 4G NB-IoT network), and two sets of custom networks centered on users.

[0070] The first type of terminal (high data transmission rate requirement, low transmission delay requirement) is assigned to the 5G NR system. The network side sends the configuration information of the 5G NR system to the first type of terminal via the basic network. After receiving the configuration information of the 5G NR system, the first type of terminal tries to access the 5G NR system.

[0071] The second type of terminal (low data transmission rate requirement, high transmission delay requirement) is assigned to the 4G NB-IoT system. The network side sends the configuration information of the 4G NB-IoT system to the second type of terminal via the basic network. After receiving the configuration information of the 4G NB-IoT system, the second type of terminal tries to access the 4G NB-IoT system.

[0072] For the third type of terminal (ultra-high data transmission rate requirement, ultra-low transmission delay requirement, 24-hour continuous service guarantee), since there is no network in the system that can support the needs of the third type of terminal, the system sends custom network requirement information to the third type of terminal, and the custom network requirement information further includes, at the same time, custom network waiting time delay information, custom network cost information, etc. After the third type of terminal confirms the custom network requirement information sent by the system, the system sends the configuration information of the custom network system to the third type of terminal. After receiving the configuration information of the system, the third type of terminal attempts to access the system.

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

[0074] In step 1602, at least two sets are divided from a plurality of system information blocks in the wireless communication system.

[0075] In a wireless communication system, system information consists of a plurality of system information blocks. The plurality of system information blocks are divided into at least two sets. Among them, the system information blocks in set 1 (i.e., basic system information blocks, including some shared configuration information in the system) are transmitted in a periodic manner, and the transmission period is configured by the network side or uses the default configuration. The system information blocks in other sets (for example, system information specific to different types of terminals) use the transmission method in which the network side transmits the first system information to the terminal via the downlink channel when the first condition is met. Here, the first condition is The network side detects the uplink information transmitted by the terminal on the uplink channel, The network side detects that the detection result corresponding to the uplink information transmitted by the terminal on the uplink channel is equal to or greater than a threshold value. The detection result includes the received power of the reference signal (Reference Signal Receiving Power, RSRP), the received quality of the reference signal (Reference Signal Receiving Quality, RSRQ), the received signal strength indicator (Received Signal Strength Indicator, RSSI), the signal-to-noise ratio (Signal to Noise Ratio, SNR), etc. It includes at least one of receiving, by the network side, the first system information transmission request information transmitted by the terminal.

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

[0077] Here, there is a mapping relationship between the uplink channel resource (the uplink channel resource includes at least time-frequency resources, and when 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 the first system information block set, that is, M (M is 1 or more) subsets of the first system information block set can constitute N (N is 1 or more) sets of uplink channel resources. That is, the terminals that request these M subsets of the first system information block set can all transmit on the N sets of uplink channel resources.

[0078] Here, there is a mapping relationship between the downlink channel resource and a subset of the first system information block set, that is, M (M is 1 or more) subsets of the first system information block set can constitute K (K is 1 or more) sets of downlink channel resources. That is, the terminals that request these M subsets of the first system information block set can all 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, when the second condition is satisfied, the terminal transmits uplink information on the uplink channel resource. The second condition is that the terminal fails to receive the system information required for this terminal type, The terminal fails to receive the system information required for the terminal sent by the network side within one time window after sending the uplink information on the uplink channel. The length of the time window may be configured by the network side or set by default. The start position of the time window may be at a position after the terminal completes sending the uplink information and after a time interval. The time interval may be set by the network side or set by default. After the terminal receives the system information block in Set 1, the resource configuration information indicating the system information required for the terminal type is not in the system information block in Set 1. The terminal enters the connected state (RRC_CONNECTED mode) from the idle state (RRC_IDLE mode). At least one of the following occurs: the update time of the terminal system arrives (or it is also called the timeout of the system update timer, that is, the time when the network side needs to send system information arrives).

[0081] Hereinafter, in conjunction with specific embodiments, the above steps will be described. In this embodiment, the downlink channel in step 1602 is Msg2 during random access. The uplink channel is Msg1 during random access.

[0082] In this embodiment, there is a mapping relationship between random access resources (physical random access channel (PRACH) time-frequency resources and random access preamble resources) and a set of system information blocks required for different types of terminals. The terminal selects corresponding PRACH resources and corresponding preambles according to the set of system information blocks required for its own type. Then, the terminal transmits a random access signal. After receiving the random access signal, the network side carries the system information required for the terminal in Msg2. Here, the system information includes at least the system bandwidth, system operating frequency, and subcarrier spacing used in the system.

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

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

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

[0087] Here, the second information includes part or all of the system information of the wireless communication system accessed by the second terminal, the timing advance information of the second terminal in the wireless communication system, the distance information from the second terminal to the TRP, the transmission power information of the second terminal, and the 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 resources indicated by the system information among them to start a random access flow.

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

[0090] Steps 1802 to 1806 are the same as steps 1702 to 1706, and detailed descriptions are omitted here.

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

[0092] In step 1810, when the third information is the scheduling information of the uplink data channel, the first terminal transmits uplink data to the TRP according to the resources indicated by the scheduling information. Here, the uplink data includes the connection establishment of the request information, and when the third information is the non-competitive random access channel configuration information, the first terminal starts a non-competitive random access procedure according to the resources indicated by the non-competitive random access channel configuration information.
