The small cell here can include: Metro cell, Micro cell, Pico Cells, Femto cells, etc. These small cells have the characteristics of small coverage and low transmit power, and are suitable for providing high-rate data transmission services.

In version 17 (R17), RedCap terminals, or RedCap devices, are introduced for scenarios with lower performance requirements. For example, but not limited to the following scenarios:

Scenario 1: Industrial Wireless Sensors. Compared with Ultra-Reliable and Low Latency Communication (URLLC) terminals, industrial wireless sensors have relatively low latency and reliability. In addition, the equipment cost and power consumption are also lower than URLLC terminals and Enhanced Mobile Broadband (eMBB) terminals.

Scenario 2: Video surveillance, which can be used for video surveillance in scenarios such as smart cities and industrial processes. In the smart city scenario, the equipment is mainly used for data collection and processing, which can realize more effective monitoring and control of urban resources, and provide more effective services to urban residents.

Scenario 3: Wearables. Examples include but are not limited to smart watches, rings, electronic health equipment, medical monitoring equipment, etc. The size of these devices is usually small.

Therefore, the above scenarios can have the following common requirements:

1. Equipment cost. Compared with version 15/16 (R15/16) eMBB terminals, the requirements for equipment cost and complexity are lower.

In one possible implementation, the bandwidth of the device and the receiving antenna can be reduced.

2. Equipment size, smaller equipment size is required.

3. Coverage, which requires coverage equivalent to or similar to that of R15/16 eMBB terminals. In this case, if the receiving antenna is lowered, the bandwidth is lowered, the power level is lowered, or the complexity of the UE is reduced to cause coverage loss, corresponding compensation is required.

For the above three scenarios, as an example and not a limitation, the performance requirements are as follows:

For scenario 1: The reliability requirement is 99.99%, the end-to-end delay 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 delay requirement can be 5-10 ms.

For scenario 2: The bit rate requirement is 2-4Mbps, the delay requirement is less than 500ms, and the reliability requirement is 99.-99.9%. Optionally, since the uplink traffic is relatively large, the high-end video rate is required to be 2-4 Mbps.

For scenario 3: You can refer to the requirements of access category 4 in the LTE system, and the rate requirement is 150Mbps/50Mbps.

In order to perform load control on the network side, UAC is introduced. Specifically, the network device can broadcast the access control information related to the access category (Access Caegory) and the access identifier (Access Identify). Further, the terminal device can broadcast the access control information according to the broadcast access control information and its own access category. Perform ACB detection with the access identifier to determine whether to allow access to the network.

In some cases, the definitions of access identifier and access category are shown in Table 1 and Table 2.

Table 1

Table 2

It should be understood that the configuration of access identifiers and access categories illustrated in Table 1 and Table 2 are only examples. With the development of standards, the diversification of services, the diversification of scenarios and other factors, the above examples can also be performed. Modifications, additions or deletions are not limited in this application.

In the case of the introduction of the RedCap terminal, since the RedCap terminal has lower performance requirements, in this case, if the terminal device is indiscriminately restricted from accessing the network through a broadcast message, the network performance will be reduced and the user experience will be affected.

In view of this, this application proposes an access control scheme, which can configure a specific access identifier for the RedCap terminal, and further configure corresponding access control information for the RedCap terminal through a broadcast message, thereby enabling independent access to the RedCap terminal Control, in other words, can achieve differentiated access control for terminals with different performance requirements, thereby improving network performance and thus improving user experience.

FIG. 2 is a schematic interaction diagram of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG. 2, the method 200 may include but is not limited to the following content:

S210. The network device broadcasts first information, where the first information includes a first access control information set list, the first access control information set list includes N first access control information sets, and the first access The access control information set is used for access control of terminal equipment with a specific access identifier, where the N is a positive integer, and the terminal equipment with the specific access identifier includes a terminal with reduced capability;

S220: The terminal device receives the first information.

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

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 Control Element (MAC) CE), etc., in the following, the first information is carried through SIB1 as an example for description, but the present application is not limited to this.

In some embodiments, the terminal device with the specific access identifier may include a terminal that requires differentiated (or independent) access control, for example, a terminal with reduced capability, or a terminal with enhanced capability. The terminal with enhanced capability may, for example, For terminals with higher performance requirements compared to ordinary terminals, or terminals suitable for other new scenarios or new services, the following takes the specific access identification terminal device as a terminal with reduced capabilities as an example. The application is not limited to this.

In the embodiment of the present application, the reduced-capacity terminal is a terminal relative to a normal terminal, and the network device may perform unified access control (UAC) on the normal terminal. For example, the normal terminal may be a table Terminals whose access identifiers in 1 are 1, 2, 11, 12, 13, 14, and 15. Compared with the ordinary terminals, the reduced-capacity terminals have lower performance requirements, and some networks may not provide services for such terminals. Therefore, differentiated access control can be performed on them to improve network performance.

In some embodiments, the reduced capability terminal may include the terminals in the foregoing three scenarios, or may also include machine type of communication (MTC) or evolved machine type of communication (eMTC). ), terminals in the Narrow Band Internet of Things (NB-IoT), etc. The terminals compared with these technologies greatly reduce the hardware complexity, data throughput and processing speed of the terminal. It is also suitable for some low-demand smart homes, smart cities, smart factories, remote monitoring, and smart transportation application scenarios. This application is not limited to this.

In some embodiments, the enhanced capability terminal may be, for example, a terminal with higher performance requirements, for example, a terminal applied to a key communication technology. This type of terminal may be, for example, NR high-reliability low-latency communication (Ultra- Reliable and Low Latency Communication (URLLC) terminals, used in some IoT scenarios that require extremely low latency and extremely high communication reliability, such as video surveillance in smart security, low latency industrial implementation control, smart driving, etc. , This application is not limited to this.

Optionally, in some embodiments, the specific access identifier may be represented by a reserved value of the access identifier. In this manner, there is no need to increase the number of bits occupied by the access identifier. For example, as shown in Table 1, the access identifiers 3-10 are reserved values. Therefore, one or more of the values can be selected to represent the specific access identifier.

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

Optionally, in some embodiments, the number of the specific access identifier is one, that is, all terminals with reduced capabilities use the same specific access identifier, for example, any one of the reserved access identifier values 3-10 The value is used as the specific access identifier.

Optionally, in other embodiments, the number of the specific access identifiers is multiple, and the multiple specific access identifiers may correspond to multiple types of reduced-capacity terminals, and each specific access identifier corresponds to A type of reduced capacity terminal.

Optionally, the multiple types of reduced-capability terminals may be divided based on different performance requirements or based on different scenarios, which is not limited in this application. By configuring corresponding access identifiers for different types of terminals with reduced capabilities, and further configuring corresponding access control information respectively, more refined access control for terminals with reduced capabilities can be achieved.

As an example, the multiple types of reduced-capacity terminals include three types of reduced-capacity terminals, respectively corresponding to the three scenarios described above, or corresponding to three levels of performance requirements, and so on.

In this case, the multiple access identifiers may include three access identifiers, respectively indicating the three types of reduced-capability terminals. As an example, the three access identifiers may include any three of the access identifier reserved values 3-10, for example, 3, 4, and 5.

In the embodiment of the present application, the network device may broadcast the first information, and the first information may include access control information used for access control of a terminal device with a specific access identifier, that is, the first access The control information set list is marked as UAC-BarringInfoSetList-v17xy for easy distinction. Optionally, the network device may also broadcast access control information used for access control of terminal devices with no specific access identification, that is, a second access control information set list, which is denoted as UAC-BarringInfoSetList for easy distinction. .

It should be understood that if there are more types of terminal devices that require separate access control, the network device may also broadcast more lists of access control information sets, or if terminal devices with no specific access identification also require more refined access For access control, the network device may also configure multiple second access control information set lists, etc., and the application is not limited to this.

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, where each first access control information set It includes a set of access control parameters, and the set of access control parameters is used to determine whether the terminal device with the specific access identifier is allowed to access.

That is, the first access control information set list is the access control information applicable to the terminal equipment of the specific access identifier, and the terminal equipment of the specific access identifier is configured with special access control information It can realize individual access control to such terminal equipment. For example, a higher restriction probability, a longer restriction duration, etc. can be configured for such terminal devices, so that the access requirements of ordinary terminals or terminals with higher performance requirements can be guaranteed first, and network performance can be improved.

Optionally, the N first access control information sets may be applicable to different situations, for example, different access categories, or different PLMNs. In other words, network equipment can configure corresponding access control information sets for different access categories or PLMNs, which is beneficial to meet the needs of different situations.

In some embodiments, the first access control information set includes first indication information (for easy distinction, it is recorded as uac-BarringForAccessIdentity-v17xy), and the first indication information is used to indicate the status of the specific access identifier The control information of the access attempt of the terminal device. As an example, the first indication information is used to indicate whether the access attempt of the terminal device of the specific access identifier is restricted.

Optionally, the first access control information set further includes a restriction factor (denoted as uac-BarringFactor-v17xy for ease of distinction) and/or restriction duration (denoted as uac-BarringTime-v17xy for ease of distinction), so 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, and so on. The restricted duration is the duration during which the terminal device is restricted from accessing.

In some embodiments, the first indication information may use a bitmap to indicate whether the access attempt of the terminal device with the specific access identifier is allowed or restricted, or is allowed or subject to the Restriction factor restriction.

As an example, the number of the specific access identifier is one. In this case, the first indication information includes one bit, and the value of the one bit is used to indicate the status of a terminal device of the specific access identifier. Whether the access attempt is allowed or restricted by the restriction factor.

As another example, there are multiple specific access identifiers. In this case, the first indication information includes multiple bits, and each bit corresponds to one specific access identifier. The value 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.

For example, when the value of each bit is 0, it means that the access attempt is allowed, and the value of 1 is that it is restricted, and it needs to be further combined with restriction factor judgment. This application does not limit the specific judgment method. As an implementation manner, a random number greater than or equal to 0 and less than 1 can be generated. If the random number is less than the restriction factor, it means that access is allowed, otherwise it means that access is prohibited.

It should be understood that the foregoing operation is performed when neither the first timer (or T309) nor the second timer (or T302) timer is running, and the access type of the terminal device is not 0. Wherein, the first timer is an access prohibition timer. When the first timer is running, the terminal device cannot initiate an access attempt. The first timer may be configured for each access type, that is, each The access type can be configured with the corresponding first timer. The second timer is started when the terminal device is denied access by the network. When the second timer is running, the terminal device is not allowed to initiate an access attempt.

Optionally, when judging that the access attempt is barred from access, the terminal device may also generate a random number greater than or equal to 0 and less than 1 (denoted as rand), start the first timer, and set the The timing of the first timer is set to (0.7+0.6*rand)*limiting factor, and an access attempt is initiated after the first timer expires.

For example, assuming that the number of the specific access identifiers is three, namely 3, 4, and 5, the first indication information may include three bits to indicate the terminal devices of the access identifiers 3, 4, and 5, respectively. Whether the access attempts are restricted. If the first indication information is 011, the restriction factor is 0.8, and the access identifier of the terminal device is 5, the terminal device determines that the access attempt is restricted, and then generates a random value. When the random number is greater than 0.8, access Attempts are forbidden, and when the random number is less than or equal to 0.8, the access attempt of the terminal device is allowed.

Optionally, the content of the second access control information set in the second access control information set list may refer to the content of the first access control information set, and the difference lies in the terminals corresponding to different access identifiers. The equipment, for the sake of brevity, will not be repeated here.

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 access category in the multiple access categories, and the second access control configuration list is used to indicate multiple public land mobile networks The access control information set corresponding to each PLMN in the PLMN. In other words, each access category can be configured with a corresponding access control information set, or each PLMN can be configured with a corresponding access control information set.

In some embodiments, the first access control configuration list includes multiple first access control configurations (denoted as UAC-BarringPerCat), and each first access control configuration corresponds to one of the multiple access categories For one access category, each first access control configuration includes at least one access control information set index.

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

Hereinafter, the description will be given by taking the determination of the target access control information of the terminal device according to the first access control configuration list as an example, and the manner of determining the target access control information of the terminal device according to the second access control configuration list is similar , I won’t repeat it here.

Specifically, the terminal device may determine whether it is in the first access control information set list or the second access control information list according to the first access control configuration list in combination with the access identifier and the access category of the terminal device. The target access control information is determined in the set list.

Case 1: The access identifier of the terminal device is the specific access identifier, that is, the terminal device is a reduced-capacity terminal.

In this case, the terminal device may search for the target access control information set in the first access control information set list.

Specifically, the terminal device may determine in the first access control configuration list that the first access control configuration corresponding to the access category of the terminal device is the target access control configuration, and further may be based on the target access control configuration. Access control information set index included in the control configuration, search for N access control information sets corresponding to the access control information set index in the first access control information set list in the first access control information set list, Determine it as the target access control information set.

Further, the access control information corresponding to the access identifier can be searched in the target access control information set according to the access identifier of the terminal device (the first indication information, restriction factor, restriction duration as described above) And other parameters), and determine whether the terminal device is allowed or restricted to access the network device according to the access control information. Refer to the previous description for the specific judgment method.

Optionally, in some embodiments, the first information may further include access type 1 selection auxiliary information, which is used to assist in determining whether to perform ACB detection for an access attempt of access type 1.

It should be understood that, in the embodiment of the present application, the above-mentioned information included in the first information may be carried by the same first information, or may also be carried by different first information, which is not limited in this application. For example, the first access control configuration list and the first access control configuration list may be carried by the same first information as the first access control information set list, or may also be carried by different first information. .

As an example, the format of the above information in SIB1 is as follows:

Wherein, the SIB1-v17xy-IEs are used to carry the first access control information set list in the embodiment 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 barring factor, uac-BarringTime represents the barring duration, uac-BarringForAccessIdentity-v17xy represents the first indication information, it is a bitmap of K bits, and K is a specific access The number of identifiers.

Optionally, in the embodiment of the present application, 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 (Access Stratum, AS) layer of the terminal device.

Case 2: The access identifier of the terminal device is not the specific access identifier, that is, the terminal device is not a reduced-capacity terminal.

In this case, the terminal device may search for the target access control information set in the second access control information set list. The specific implementation is similar to case 1, and will not be repeated here.

Therefore, in the embodiment of the present application, by configuring the access control information applicable to the terminal device with the specific access identifier, the terminal device with the specific access identifier can perform access control based on the corresponding access control information. It is helpful to realize differentiated management of access control for terminal devices with different performance requirements, improve network performance, and further enhance user experience.
