[0025] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art without creative effort regarding the embodiments of this application are within the scope of protection of this application.

[0026] The embodiments of this application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced Long Term Evolution (LTE-A) system, New Radio (NR) system, evolution system of NR system, LTE-based access to unlicensed spectrum (LTE-U) system, NR-based access to unlicensed spectrum (NR-U) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next-generation communication systems, or other communication systems, etc.

[0027] Traditional communication systems typically support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communication but also, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC) communication, and vehicle-to-vehicle (V2V) communication. The embodiments of this application can also be applied to these communication systems.

[0028] Optionally, the communication system in this application embodiment can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, or a standalone (SA) network deployment scenario.

[0029] The embodiments of this application do not limit the spectrum to be applied. For example, the embodiments of this application can be applied to licensed spectrum, unlicensed spectrum, or shared spectrum.

[0030] For example, the communication system 100 used in the embodiments of this application is as follows: Figure 1 As shown. The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal, terminal). The network device 110 can provide communication coverage for a specific geographical area and can communicate with terminal devices located within that coverage area.

[0031] Figure 1 An exemplary embodiment shows a network device and two terminal devices. Optionally, the communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area. This application embodiment does not limit this.

[0032] Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in this embodiment.

[0033] It should be understood that devices with communication functions in the network / system of this application embodiment can be referred to as communication devices. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above, which will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as network controllers, mobility management entities and other network entities. This application embodiment does not limit this.

[0034] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0035] It should be understood that the term "instruction" mentioned in the embodiments of this application can be a direct instruction, an indirect instruction, or an indication of a relationship. For example, A instructing B can mean that A directly instructs B, such as B being able to obtain information through A; it can also mean that A indirectly instructs B, such as A instructing C, so B can obtain information through C; or it can mean that there is a relationship between A and B.

[0036] In the description of the embodiments of this application, the term "correspondence" may indicate that there is a direct or indirect correspondence between two things, or that there is an association between two things, or that there is a relationship of instruction and being instructed, configuration and being configured, etc.

[0037] This application describes various embodiments in conjunction with terminal devices and network devices, wherein: the terminal device may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device, etc. The terminal device may be a station (ST) in a WLAN, a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA) device, handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, and next-generation communication system, such as terminal device in an NR network or terminal device in a future evolved Public Land Mobile Network (PLMN) network, etc.

[0038] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0039] Network devices can be devices used to communicate with mobile devices. Network devices can be access points (APs) in WLANs, base stations (BTSs) in GSM or CDMA, base stations (NodeBs, NBs) in WCDMA, evolved base stations (eNBs or eNodeBs) in LTE, relay stations or access points, or in-vehicle devices, wearable devices, and network devices or base stations (gNBs) in NR networks, or network devices in future evolved PLMN networks, etc.

[0040] In this embodiment, the network device may have mobility characteristics; for example, the network device may be a mobile device. Optionally, the network device may be a satellite or a balloon station. For example, the satellite may be a low Earth orbit (LEO) satellite, a medium Earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. Optionally, the network device may also be a base station located on land, water, or other similar locations.

[0041] In this embodiment, the network device provides services to the cell, and the terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell can be the cell corresponding to the network device (e.g., base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0042] Version 17 (R17) introduced RedCap endpoints, or RedCap devices, for scenarios with lower performance requirements. Examples include, but are not limited to, the following scenarios:

[0043] Scenario 1: Industrial Wireless Sensors. Compared to Ultra-Reliable and Low-Latency Communication (URLLC) terminals, industrial wireless sensors have relatively lower latency and reliability requirements. Furthermore, their device cost and power consumption are lower than URLLC terminals and Enhanced Mobile Broadband (eMBB) terminals.

[0044] Scenario 2: Video surveillance can be used in smart cities, industrial processes, and other similar scenarios. In smart city scenarios, the equipment is mainly used for data collection and processing, thereby enabling more effective monitoring and control of urban resources and providing more efficient services to city residents.

[0045] Scenario 3: Wearables. Examples include, but are not limited to, smartwatches, rings, electronic health devices, and medical monitoring devices. These devices are typically small in size.

[0046] Therefore, the above scenarios may have the following common requirements:

[0047] 1. Equipment cost: Compared with the eMBB terminal of version 15 / 16 (R15 / 16), the requirements for equipment cost and complexity are lower.

[0048] In one possible implementation, the device's bandwidth and receiving antenna can be reduced.

[0049] 2. Equipment size: The equipment size should be relatively small.

[0050] 3. Coverage: The coverage should be comparable to or similar to that of eMBB terminals in R15 / 16. In this case, if coverage loss occurs due to reducing the receiving antenna, bandwidth, power level, or other methods that reduce UE complexity, appropriate compensation is required.

[0051] For the three scenarios mentioned above, as examples rather than limitations, the performance requirements are as follows:

[0052] For Scenario 1: the reliability requirement is 99.99%, the end-to-end latency is 100ms, the bit rate requirement is 2Mbps, the device is stationary, and the battery life is several years. Optionally, for safety-related sensors, the latency requirement can be 5-10ms.

[0053] For scenario 2: the bit rate requirement is 2-4 Mbps, the latency requirement is less than 500 ms, and the reliability requirement is 99.9%-99.9%. Optionally, due to the large uplink traffic, the high-end video rate requirement is 2-4 Mbps.

[0054] For scenario 3: the requirements for access category 4 in the LTE system can be referenced, with a rate requirement of 150Mbps / 50Mbps.

[0055] To perform network-side load control, User-Agent Control (UAC) is introduced. Specifically, network devices can broadcast access control information related to the Access Category and Access Identifier. Furthermore, terminal devices perform ACB (Active Access Control) checks based on the broadcast access control information and their own access category and access identifier to determine whether to allow network access.

[0056] In some cases, the definitions of access identifiers and access categories are shown in Tables 1 and 2.

[0057] Table 1

[0058]

[0059]

[0060] Table 2

[0061]

[0062]

[0063] It should be understood that the configuration of access identifiers and access categories shown in Tables 1 and 2 are merely examples. With the development of standards, the diversification of services, the diversification of scenarios, and other factors, the above examples may be modified, added to, or deleted. This application does not limit this.

[0064] When RedCap terminals are introduced, since they have lower performance requirements, indiscriminately restricting terminal devices from accessing the network via broadcast messages would reduce network performance and affect user experience.

[0065] In view of this, this application proposes an access control scheme that can configure a specific access identifier for RedCap terminals and further configure corresponding access control information for RedCap terminals through broadcast messages, thereby enabling independent access control for RedCap terminals. In other words, it can realize differentiated access control for terminals with different performance requirements, thereby improving network performance and thus enhancing user experience.

[0066] Figure 2 This is a schematic interactive diagram of a wireless communication method 200 according to an embodiment of this application, such as... Figure 2 As shown, the method 200 may include, but is not limited to, the following:

[0067] S210, the network device broadcasts first information, the first information including a list of first access control information sets, the list of first access control information sets including N first access control information sets, the first access control information sets being used for access control of terminal devices with specific access identifiers, wherein N is a positive integer, and the terminal devices with specific access identifiers include degraded capability terminals;

[0068] S220, the terminal device receives the first information.

[0069] Optionally, in some embodiments, the first information may be carried in the Master Information Block (MIB) or the System Information Block (SIB) information, for example, it may be carried in SIB1.

[0070] In other embodiments, the first information may also be carried in other messages or signaling, such as Radio Resource Control (RRC) signaling, Media Access Control (MAC) Element, etc. Hereinafter, the first information is carried by SIB1 as an example, but this application is not limited thereto.

[0071] In some embodiments, the terminal device with the specific access identifier may include a terminal that requires differentiated (or independent) access control, such as a reduced-capability terminal or an enhanced-capability terminal. The enhanced-capability terminal may be a terminal with higher performance requirements than a normal terminal, or a terminal suitable for other new scenarios or new services. Hereinafter, the terminal device with the specific access identifier is a reduced-capability terminal as an example for illustration, but this application is not limited thereto.

[0072] In this embodiment, the reduced-capability terminal is a terminal relative to a regular terminal. The network device can perform unified access control (UAC) on the regular terminal. For example, the regular terminal can be a terminal with access identifiers 1, 2, 11, 12, 13, 14, or 15 in Table 1. Compared to the regular terminal, the reduced-capability terminal has lower performance requirements, and some networks may not provide services to such terminals. Therefore, differentiated access control can be applied to it to improve network performance.

[0073] In some embodiments, the reduced-capability terminal may include terminals from the three scenarios described above, or it may include terminals using machine-type communication (MTC) or evolved machine-type communication (eMTC), narrowband Internet of Things (NB-IoT), etc. These technologies significantly reduce the hardware complexity, data throughput, and processing speed of the terminal. They are also applicable to some lower-requirement smart home, smart city, smart factory, remote monitoring, and smart transportation applications. This application is not limited thereto.

[0074] In some embodiments, the enhanced capability terminal may be a terminal with high performance requirements, such as a terminal applied to key communication technologies. This type of terminal may be an Ultra-Reliable and Low Latency Communication (URLLC) terminal, which is applied to some Internet of Things scenarios that require extremely low latency and extremely high communication reliability, such as video surveillance in smart security, low-latency industrial implementation control, and intelligent driving. This application is not limited to this.

[0075] Optionally, in some embodiments, the specific access identifier can be represented by a reserved value of the access identifier. This method eliminates the need to increase the number of bits occupied by the access identifier. For example, as shown in Table 1, access identifiers 3-10 are reserved values; therefore, one or more of these values ​​can be selected to represent the specific access identifier.

[0076] In other embodiments, the specific access identifier may also be represented by other values ​​that do not conflict with existing access identifiers, and this application is not limited to this. For example, it may be represented by values ​​other than 0-15, such as 16, 20, etc. In this case, the number of bits occupied by the access identifier needs to be increased.

[0077] Optionally, in some embodiments, the number of specific access identifiers is one, that is, all degraded terminals use the same specific access identifier, for example, any one of the access identifier reserved values ​​3-10 is used as the specific access identifier.

[0078] Optionally, in other embodiments, the number of specific access identifiers is multiple, and the multiple specific access identifiers can correspond to multiple types of degraded terminals, with each specific access identifier corresponding to one type of degraded terminal.

[0079] Optionally, the various types of degraded terminals can be categorized based on different performance requirements or different scenarios, and this application does not limit this. By configuring corresponding access identifiers for different types of degraded terminals and further configuring corresponding access control information for each, more refined access control of degraded terminals can be achieved.

[0080] As an example, the various types of reduced-capability terminals include three types of reduced-capability terminals, corresponding to the three scenarios mentioned above, or corresponding to three levels of performance requirements, etc.

[0081] In this case, the plurality of access identifiers may include three access identifiers, each indicating one of the three types of degraded terminals. As an example, the three access identifiers may include any three values ​​from access identifier reservation values ​​3-10, such as 3, 4, and 5.

[0082] In this embodiment, the network device may broadcast the first information, which may include access control information for access control of terminal devices with a specific access identifier, i.e., a first access control information set list, denoted as UAC-BarringInfoSetList-v17xy for easy distinction. Optionally, the network device may also broadcast access control information for access control of terminal devices without a specific access identifier, i.e., a second access control information set list, denoted as UAC-BarringInfoSetList for easy distinction.

[0083] It should be understood that if there are more terminal devices that require individual access control, the network device may broadcast more access control information set lists, or if terminal devices that are not specific access identifiers also require more granular access control, the network device may configure multiple second access control information set lists for them, etc., and this application is not limited thereto.

[0084] In some embodiments, the first access control information set list includes N first access control information sets, which are denoted as UAC-BarringInfoSet-v17xy for easy distinction. Each first access control information set includes a set of access control parameters, which are used to determine whether the terminal device with the specific access identifier is allowed to access.

[0085] In other words, the first access control information set list contains access control information applicable to terminal devices with the specific access identifier. By configuring dedicated access control information for terminal devices with the specific access identifier, individual access control for such terminal devices can be achieved. For example, a higher restriction probability and a longer restriction duration can be configured for such terminal devices, thereby prioritizing the access needs of ordinary terminals or terminals with higher performance requirements and improving network performance.

[0086] Optionally, the N first access control information sets can be applied to different situations, such as different access categories or different PLMNs. In other words, network devices can configure corresponding access control information sets for different access categories or PLMNs, which helps meet the needs of different situations.

[0087] In some embodiments, the first access control information set includes first indication information (denoted as uac-BarringForAccessIdentity-v17xy for easy distinction), which is used to indicate control information for the access attempt of the terminal device with the specific access identifier. As an example, the first indication information is used to indicate whether the access attempt of the terminal device with the specific access identifier is restricted.

[0088] Optionally, the first access control information set further includes a restriction factor (denoted as uac-BarringFactor-v17xy for easy distinction) and / or a restriction duration (denoted as uac-BarringTime-v17xy for easy distinction). The first indication information is used to indicate whether the access attempt of the terminal device with the specific access identifier is allowed or restricted by the restriction factor. The restriction factor is used to indicate the probability of being restricted, or the probability of being allowed, etc. The restriction duration is the duration for which the terminal device's access is restricted.

[0089] In some embodiments, the first indication information may be in the form of a bitmap to indicate whether the access attempt of the terminal device of the specific access identifier is allowed or restricted, or whether it is allowed or restricted by the restriction factor.

[0090] As an example, if the number of specific access identifiers is one, the first indication information includes one bit, the value of which is used to indicate whether an access attempt by a terminal device with the specific access identifier is allowed or restricted by the restriction factor.

[0091] As another example, if there are multiple specific access identifiers, the first indication information includes multiple bits, each bit corresponding to one specific access identifier, and the value of each bit is used to indicate whether the access attempt of the terminal device corresponding to the specific access identifier is allowed or restricted by the restriction factor.

[0092] For example, a value of 0 for each bit indicates that the access attempt is allowed, while a value of 1 indicates that it is restricted, requiring further judgment based on a restriction factor. This application does not limit the specific judgment method. As one implementation method, a random number greater than or equal to 0 and less than 1 can be generated. If this random number is less than the restriction factor, access is allowed; otherwise, access is prohibited.

[0093] It should be understood that the above operations are performed when neither the first timer (or T309) nor the second timer (or T302) is running, and the access type of the terminal device is not 0. The first timer is an access prohibition timer; when this first timer is running, the terminal device cannot initiate an access attempt. This first timer can be configured for each access type, meaning each access type can have a corresponding first timer. The second timer is started when the terminal device is denied access by the network; when this second timer is running, the terminal device is not allowed to initiate any further access attempts.

[0094] Optionally, when it is determined that the access attempt is blocked, the terminal device may also generate a random number (denoted as rand) that is greater than or equal to 0 and less than 1, start the first timer, and set the timing of the first timer to (0.7+0.6*rand)*limiting factor. After the first timer expires, the access attempt is initiated again.

[0095] For example, assuming there are three specific access identifiers, namely 3, 4, and 5, the first indication information may include three bits, indicating whether the access attempt of the terminal device with access identifiers 3, 4, and 5 is restricted. If the first indication information is 011, the restriction factor is 0.8, and the access identifier of the terminal device is 5, and the terminal device determines that the access attempt is restricted, it generates a random value. When the random number is greater than 0.8, the access attempt is prohibited; when the random number is less than or equal to 0.8, the access attempt of the terminal device is allowed.

[0096] Optionally, the content of the second access control information set in the second access control information set list can refer to the content of the first access control information set, the difference being the terminal devices corresponding to different access identifiers. For the sake of brevity, this will not be elaborated here.

[0097] Optionally, in some embodiments, the first information further includes a first access control configuration list (denoted as UAC-BarringPerCatList) and / or a second access control configuration list (denoted as UAC-BarringPerPLMN-List). The first access control configuration list is used to indicate the access control information set corresponding to each of the multiple access categories, and the second access control configuration list is used to indicate the access control information set corresponding to each of the multiple public land mobile networks (PLMNs). That is, each access category may be configured with a corresponding access control information set, or each PLMN may be configured with a corresponding access control information set.

[0098] In some embodiments, the first access control configuration list includes a plurality of first access control configurations (denoted as UAC-BarringPerCat), each first access control configuration corresponding to one of the plurality of access categories, and each first access control configuration including at least one access control information set index.

[0099] In some embodiments, the second access control configuration list includes a plurality of second access control configurations (denoted as UAC-BarringPerPLMN), each second access control configuration corresponds to one of the plurality of PLMNs, and each second access control configuration includes at least one access control information set index.

[0100] The following explanation uses the determination of the target access control information of the terminal device based on the first access control configuration list as an example. The method of determining the target access control information of the terminal device based on the second access control configuration list is similar and will not be repeated here.

[0101] Specifically, the terminal device can determine whether to select the target access control information from the first access control information set list or the second access control information set list based on the first access control configuration list and in combination with the terminal device's access identifier and access category.

[0102] Case 1: The access identifier of the terminal device is the specific access identifier, that is, the terminal device is a terminal with reduced capabilities.

[0103] In this case, the terminal device can search for the target access control information set in the first access control information set list.

[0104] Specifically, the terminal device can determine the first access control configuration corresponding to the access category of the terminal device as the target access control configuration in the first access control configuration list. Furthermore, it can search for the access control information set corresponding to the access control information set index in N first access control information sets in the first access control information set list according to the access control information set index included in the target access control configuration, and determine it as the target access control information set.

[0105] Furthermore, the access control information corresponding to the access identifier of the terminal device can be searched in the target access control information set (such as the first indication information, restriction factor, restriction duration, and other parameters mentioned above). Based on this access control information, it can be determined whether the terminal device's access to the network device is permitted or restricted. For specific determination methods, please refer to the relevant description above.

[0106] Optionally, in some embodiments, the first information may further include access type 1 selection assistance information, used to assist in determining whether to perform ACB detection for access type 1 access attempts.

[0107] It should be understood that, in the embodiments of this application, the information included in the first information may be carried by the same first information or by different first information, and this application does not limit this. For example, the first access control configuration list and the first access control configuration list may be carried by the same first information or by different first information.

[0108] As an example, the above information is formatted as follows in SIB1:

[0109]

[0110]

[0111]

[0112] Wherein, SIB1-v17xy-IEs is used to carry the first access control information set list in the embodiments of this application, UAC-BarringInfoSetList-v17xy represents the first access control information set list, UAC-BarringInfoSet-v17xy represents the first access control information set, uac-BarringFactor represents the restriction factor, uac-BarringTime represents the restriction duration, uac-BarringForAccessIdentity-v17xy represents the first indication information, which is a bitmap of K bits, where K is the number of specific access identifiers.

[0113] Optionally, in this embodiment, the access identifier of the terminal device may be obtained from the non-access stratum (NAS) layer of the terminal device. The access category of the terminal device may be obtained from the NAS layer or the access stratum (AS) layer of the terminal device.

[0114] Case 2: The access identifier of the terminal device is not the specific access identifier, that is, the terminal device is not a terminal with reduced capabilities.
