[0057] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0058] 1. Low Power Wide Area (LPWA).

[0059] PWA technology is used to meet the communication needs of IoT devices for low power consumption, wide area coverage, and low cost. LPWA technology has a longer communication range, lower power consumption, and lower cost, making it suitable for the large-scale connectivity and low power consumption requirements of IoT applications.

[0060] Existing cellular IoT devices, such as Narrow Band Internet of Things (NB-IoT) devices, will reach the end of their lifespan by the time 6G is deployed. Therefore, 6G presents an opportune time to deploy a new generation of higher-performance, lower-cost, and larger-scale LPWA devices. With the rollout of 6G, the LPWA market is expected to experience strong growth, penetrating a wide variety of commercially valuable application scenarios (such as logistics management, smart homes, and smart cities).

[0061] Existing 4G LPWA solutions, such as NB-IoT, and 4G Enhanced Mobile Broadband (eMBB) are designed as two independent Radio Access Technologies (RATs) and are not well compatible. Because NB-IoT user equipment and eMBB user equipment have significant differences in their physical layers, this not only increases the standardization workload but also raises the cost of NB-IoT user equipment. Furthermore, NB-IoT user equipment requires dedicated NB-IoT base stations, which increases network deployment costs and operational efficiency. When designing 6G LPWA solutions, 6G LPWA and eMBB should be as compatible as possible.

[0062] Correspondingly, on the network side, a single 6G base station will simultaneously serve LPWA and eMBB devices, dynamically optimizing resource allocation for instantaneous service requests. To reduce network deployment and operating costs, future 6G mobile communication systems will consider the organic integration of broadband and narrowband communication as much as possible.

[0063] In some embodiments, LPWA may refer to a type of terminal (UE). This type of terminal (e.g., LPWA UE, IoTDevice) has at least one of the following wireless capabilities limited compared to a normal capability terminal (e.g., eMBB UE): transmission bandwidth capability; RF radio frequency capability; transmit power capability; error detection demodulation / decoding capability, etc.

[0064] In some embodiments, LPWA can refer to a type of terminal feature or feature combination (UE feature, UE feature combination). This type of terminal feature or feature combination includes at least one of the following: Maximum Coverage Extension Level, Network Energy Saving (NES), Power Saving, Small Data Transmission, etc.

[0065] It should be noted that in the embodiments of this application, the description of the terminal can be understood or replaced as device.

[0066] II. NB-IoT / LTE-M Access Denial Mechanism.

[0067] Cell bar based on terminal category: For certain low-end UEs, an access bar mechanism based on UE category has been introduced. For example, if this access bar mechanism is enabled in a cell (SIB1 does not carry category0 allowed), and the UE's access category matches, the UE considers itself to be prohibited from accessing the cell.

[0068] Cell bar based on Coverage Enhancement level (CE-level): Provided the cell access prohibition mechanism is enabled (SIB14 / SIB14-NB carries eab-PerRSRP), the NB-IoT / MTC UE considers itself prohibited from accessing the cell if any of the following conditions are met:

[0069] Condition 1: The eab-PerRSRP configuration value is thresh0, and the UE determines that it is within the enhanced coverage area according to the TS 36.304 protocol.

[0070] Condition 2: The eab-PerRSRP configuration value is thresh1, and the reference signal received power (RSRP) measured by the UE is less than the first threshold (the first configuration value in rsrp-ThresholdsPrachInfoList);

[0071] Condition 3: The eab-PerRSRP configuration value is thresh2, and the RSRP measured by the UE is less than the second threshold (the second configuration value in rsrp-ThresholdsPrachInfoList);

[0072] Condition 4: The eab-PerRSRP configuration value is thresh3, and the RSRP measured by the UE is less than the third threshold (the third configuration value in rsrp-ThresholdsPrachInfoList);

[0073] Based on this, access requests initiated for specific services or specific users can bypass the aforementioned access prohibition mechanism. Specifically, specific services are those that contain exception data from Emergency (eMTC) / Measurement Opportunity (MO) events (NB-IoT), and specific users are those whose AccessClass stored in the Universal Subscriber Identity Module (USIM) falls within the range of 11-15.

[0074] Third, NR introduces a unified access control (UAC) mechanism, which introduces two dimensions for UE: access category (AC) and access identity (AI).

[0075] The access identifier represents the user's identity characteristics and is written in the SIM card, with a value range of 0 to 15. Among them, 4 to 10 are reserved access identifiers.

[0076] The access category represents the service attribute initiated by the UE for access, with a value range of 0 to 63. Among them, 0 to 10 are standardized access categories, 11 to 31 are reserved standardized access categories, and 32 to 63 are access categories that can be defined by the operator.

[0077] The System Information Block (SIB) 1 broadcasts at least one set of access control parameter configurations (including access probability and maximum duration of access prohibition timer). This can be a separate set of access parameters associated with each AC and each PLMN (uac-BarringPerPLMN-List), or a common set of access parameter configurations associated with all ACs and all PLMNs (uac-BarringForCommon), i.e., a common access parameter configuration.

[0078] The UE-side access control check process is a mechanism based on access probability and timers, with the core idea as follows:

[0079] If AC is 0 (Paging triggers access), then the access attempt is considered allowed.

[0080] For other access categories, if SIB1 includes access control configuration, i.e., uac-BarringPerPLMN-List or uac-BarringForCommon, then the access attempt corresponding to the access category AC and access identifier AI is determined to be prohibited or allowed based on the access control configuration; if SIB1 does not include access control configuration, then the access attempt is considered allowed.

[0081] If an access class AC is disabled, the corresponding T390 timer for that access class is started. If the T390 timer times out, the access ban is considered lifted.

[0082] The access prohibition mechanism adopted by NB-IoT / LTE-M is relatively simple, mainly introducing the Cell bar concept based on UE category / CE-level. Considering the trend of unifying the design of LPWA and eMBB air interfaces in future communication systems (such as 6G), from the network side perspective, LPWA and eMBB can be co-located and share the cell's common control channel resources. From the terminal side perspective, any UE (including LPWA UE and eMBB UE) can be served by the same network node, and eMBB UEs, like LPWA UEs, support some basic radio capabilities or features, such as coverage enhancement. Therefore, for 6G communication system design, the need and scenario for network-side load control based on UE category / CE-level still holds, but the following drawbacks exist:

[0083] 1. Regarding capability categories, the current NB-IoT / LTE-M capability categories are mainly classified based on the UE's uplink and downlink peak rates, which is not suitable for defining 6G capability categories under the premise of unified LPWA and eMBB air interface design. Therefore, we hope to implement a unified Cell barred mechanism based on the new 6G capability category framework.

[0084] 2. Currently, NB-IoT / LTE-M / Redcap adopt a "one-size-fits-all" mechanism similar to Cellbarred for UEs at different coverage enhancement levels. If this is directly applied to the 6G air interface design, it will negatively impact eMBB UEs, causing them to be blocked from access for extended periods. Therefore, we are considering a UAC mechanism (based on access probability and access blocking timer) for 6G to ensure that eMBB UEs, even at lower coverage enhancement levels, still have a certain probability of accessing cell services. This would minimize the negative impact on eMBB UEs within the UE-side LPWA and eMBB converged design framework.

[0085] In the design of future communication systems (such as 6G), how to achieve network-side load control and minimize the adverse effects on eMBB UEs to meet the needs of joint access for LPWA UEs and eMBB UEs has become an urgent problem to be solved. To address this, the information transmission method of this application is proposed.

[0086] The information transmission method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0087] Reference Figure 2 This application provides an information transmission method, such as... Figure 2 As shown, the information transmission method provided in this application embodiment includes:

[0088] Step 201: The terminal receives system information of the first cell from the network-side device, the system information carrying at least one of the first parameter configuration and the second parameter configuration;

[0089] Step 202: The terminal performs a first operation based on the system information, the first operation including at least one of the following:

[0090] The first cell is allowed or denied access based on the first parameter configuration.

[0091] The access attempt of the terminal is allowed or denied based on the configuration of the second parameter.

[0092] The first parameter configuration is used to indicate at least one of the information on allowed cell access and information on prohibited cell access via a bitmap or list;

[0093] The second parameter configuration is associated with the first information, which includes the coverage enhancement level.

[0094] In this embodiment of the application, the above-mentioned system information may include SIB1, that is, the above-mentioned first parameter configuration and second parameter configuration can be carried through SIB1.

[0095] Optionally, the first parameter configuration can be used to set whether the first cell is allowed to access or is prohibited from access, thereby flexibly controlling the number of terminals accessing the first cell and improving the communication performance of the terminals.

[0096] It should be noted that when indicating allowed cell access information through bitmaps or lists, the indicated information can be increased by increasing the length of the bitmap or the list, thereby improving the flexibility of indicating allowed and / or prohibited cell access information.

[0097] Optionally, the access attempts of a specified terminal can be allowed or denied through the configuration of the second parameter, thereby controlling the number of terminals accessing the first cell and improving the communication performance of the terminals.

[0098] In this embodiment, a terminal receives system information of a first cell from a network-side device. The system information carries at least one of a first parameter configuration and a second parameter configuration. The terminal performs a first operation based on the system information, the first operation including at least one of the following: determining whether the first cell is allowed or denied access based on the first parameter configuration; and determining whether the terminal's access attempt is allowed or denied based on the second parameter configuration. The first parameter configuration is used to indicate at least one of the information on allowed and denied access cells via a bitmap or list. The second parameter configuration is associated with first information, which includes a coverage enhancement level. Thus, since at least one of the first and second parameter configurations can control terminal access to the cell, the number of terminals accessing the first cell can be controlled, avoiding an excessive number of terminals accessing the cell. Therefore, this embodiment improves the terminal's communication performance.

[0099] Optionally, in some embodiments, determining whether the first cell is allowed or denied access based on the first parameter configuration includes:

[0100] The first cell is allowed or denied access based on the first capability type and the first parameter configuration, where the first capability type is the capability type of the terminal.

[0101] In this embodiment of the application, the first capability type mentioned above can be understood as a capability type defined based on 6G or 7G, or a capability type defined by a future protocol. The capability type can be determined based on one or more parameters, such as at least one of the following: wireless capability information (e.g., duplex mode), service characteristic information (e.g., Small Data Transmission (SDT) service), and terminal characteristic information (e.g., power consumption information). Wherein, a capability type defined based on 6G or 7G, or a capability type defined by a future protocol, means that the aforementioned wireless capability information, service characteristic information, and terminal characteristic information are parameter information defined by 6G, 7G, or a future protocol.

[0102] For example, a first capability type is described as follows: the terminal duplex mode is frequency division duplex, the power consumption is less than or equal to a first value, and it supports SDT services;

[0103] For example, one type of first capability is described as follows: the terminal duplex mode is frequency division duplex, the power consumption is less than or equal to the second value, and it does not support small data packet SDT services.

[0104] Optionally, determining whether the first cell is allowed or denied access based on the first capability type and the first parameter configuration can be understood as determining whether the first capability type is allowed or denied access in the first cell based on the first capability type and the first parameter configuration.

[0105] Optionally, in some embodiments, determining whether the first cell is allowed or denied access based on the first capability type and the first parameter configuration includes:

[0106] If the first capability type meets the first condition, it is determined that the first cell is allowed to access;

[0107] If the first capability type meets the second condition, it is determined that the first cell is prohibited from access;

[0108] The first condition includes:

[0109] The information of the allowed cell indicated by the first parameter configuration is associated with at least one second capability type, and the first capability type is included in the at least one second capability type;

[0110] The information of the prohibited cell indicated by the first parameter configuration is associated with at least one third capability type, and the first capability type is not included in the at least one third capability type;

[0111] The second condition includes:

[0112] The information of the allowed cell indicated by the first parameter configuration is associated with at least one second capability type, which is not included in the at least one second capability type;

[0113] The information of the prohibited cell indicated by the first parameter configuration is associated with at least one third capability type, and the first capability type is included in the at least one third capability type.

[0114] In this embodiment of the application, the aforementioned first parameter configuration can be understood as a cell-barred parameter configuration. For example, the first parameter configuration can be sent via cell-barred parameter configuration signaling. This first parameter configuration describes whether at least one first capability type is allowed or prohibited from accessing the first cell. The information regarding allowed and prohibited cell access can be understood as information regarding whether at least one first capability type is allowed or prohibited from accessing the first cell.

[0115] Optionally, determining that the first cell is allowed to access when the first capability type meets the first condition can be understood as: determining that the first capability type is allowed to access the first cell when the first capability type meets the first condition, or determining that the terminal of the first capability type is allowed to access the first cell.

[0116] It should be noted that "capability type allowed access" usually refers to the network determining whether a device meets the access conditions based on the hardware or software capabilities reported by the terminal device (such as a mobile phone or IoT device), and thus deciding whether to allow the device to connect to the network or use a specific service.

[0117] Optionally, determining that the first cell is prohibited from access when the first capability type meets the second condition can be understood as: determining that the first capability type is prohibited from accessing the first cell when the first capability type meets the second condition, or determining that the terminal of the first capability type is prohibited from accessing the first cell.

[0118] Optionally, the aforementioned at least one second capability type can be understood as a capability type that is allowed to access the first cell. When the first capability type belongs to at least one second capability type, it means that the first capability type is allowed to access the first cell. When a capability type does not belong to at least one second capability type, it means that the first capability type is prohibited from accessing the first cell.

[0119] Optionally, the aforementioned at least one third capability type can be understood as a capability type that is prohibited from accessing the first cell. When the first capability type belongs to at least one third capability type, it means that the first capability type is prohibited from accessing the first cell. When a capability type does not belong to at least one third capability type, it means that the first capability type is allowed to access the first cell.

[0120] Optionally, in some embodiments, the terminal is configured with at least two first capability types, and the step of determining whether the first cell is allowed or denied access based on the first capability type and the first parameter configuration includes:

[0121] Based on the at least two first capability types and the first parameter configuration, it is determined whether the first cell is allowed to access or is prohibited from access.

[0122] Wherein, if a third condition is met, the first cell is determined to be allowed access, and the third condition includes any one of the following:

[0123] Based on the highest level of the first capability type among the at least two first capability types, it is determined that the first cell is allowed to access;

[0124] Based on the lowest level of the first capability type among the at least two first capability types, it is determined that the first cell is allowed to access;

[0125] Based on a first capability type randomly selected from the at least two first capability types, it is determined that the first cell is allowed to access.

[0126] Based on at least one of the at least two first capability types, it is determined that the first cell is allowed to access;

[0127] Wherein, if the fourth condition is met, it is determined that the first cell is prohibited from access, and the fourth condition includes any one of the following:

[0128] Based on the highest level of the first capability type among the at least two first capability types, it is determined that the first cell is prohibited from access;

[0129] Based on the lowest level of the first capability type among the at least two first capability types, it is determined that the first cell is prohibited from access;

[0130] Based on a first capability type randomly selected from the at least two first capability types, it is determined that the first cell is prohibited from access.

[0131] Based on all of the at least two first capability types, it is determined that the first cell is prohibited from access.

[0132] Optionally, the terminal may obtain its first capability type through at least one of the following methods:

[0133] 1. As stipulated in the agreement;

[0134] 2. Terminal pre-configuration (UE pre-configuration);

[0135] 3. Core network configuration, for example, AMF configures the UE via NAS signaling.

[0136] Optionally, when the terminal is configured with at least two first capability types, the first capability type currently used by the terminal can be determined based on the current usage scenario or actively set by the user.

[0137] In this embodiment of the application, satisfying the third condition can be understood as determining that the first cell is allowed access (or that the terminal is allowed access in the first cell) when one or more first capability types are allowed access. Satisfying the fourth condition can be understood as determining that the first cell is prohibited access (or that the terminal is prohibited access in the first cell) when one or more first capability types are prohibited access.

[0138] Optionally, determining whether the first cell is allowed to access or is prohibited from access based on the highest level of the at least two first capability types can be understood as: determining whether the first cell is allowed to access based on the highest level of the at least two first capability types. For example, when the highest level of the first capability type allows access to the first cell, it can be determined that the first cell is allowed to access; when the highest level of the first capability type prohibits access to the first cell, it can be determined that the first cell is prohibited from access.

[0139] Optionally, determining whether the first cell is allowed to access or is prohibited from access based on the lowest level of the at least two first capability types can be understood as: determining whether the first cell is allowed to access based on the lowest level of the at least two first capability types. For example, when the lowest level of the first capability type allows access to the first cell, it can be determined that the first cell is allowed to access; when the lowest level of the first capability type prohibits access to the first cell, it can be determined that the first cell is prohibited from access.

[0140] It should be understood that "highest level" can be interpreted as the highest capability level, and "lowest level" as the lowest capability level. For example, a capability type supporting SDT services has a higher capability level than a capability type that does not support SDT services. Similarly, a capability type supporting full-duplex communication has a higher capability level than a capability type that does not support full-duplex communication. Assume a terminal is configured with a first capability type 1 and a second capability type 2. First capability type 1 is: supports frequency division duplex, power consumption is less than or equal to a first value, and supports SDT services; first capability type 2 is: does not support frequency division duplex, power consumption is less than or equal to a first value, and does not support SDT services. In this case, first capability type 1 can be considered the highest capability level, and first capability type 2 can be considered the lowest capability level.

[0141] Optionally, determining that the first cell is allowed to access based on at least one of the at least two first capability types can be understood as: judging each of the first capability types one by one, if any first terminal capability is allowed to access the first cell, then the first cell is considered to be allowed to access; otherwise, the first cell is considered to be prohibited from access.

[0142] Optionally, determining that the first cell is allowed to access based on all of the at least two first capability types can be understood as: judging each of the first capability types one by one; if all the first capability types are allowed to access the first cell, then the first cell is considered to be allowed to access; otherwise, the first cell is considered to be prohibited from access.

[0143] Optionally, determining that the first cell is prohibited from access based on at least one of the at least two first capability types can be understood as: judging each of the first capability types one by one, if any first terminal capability is prohibited from access in the first cell, then the first cell is considered to be prohibited from access; otherwise, the first cell is considered to be allowed to access.

[0144] Optionally, determining that the first cell is prohibited from access based on all of the at least two first capability types can be understood as: judging each of the first capability types one by one; if all the first capability types are prohibited from access in the first cell, then the first cell is considered to be prohibited from access; otherwise, the first cell is considered to be allowed to access.

[0145] In this embodiment of the application, since the conditions for allowing or prohibiting access to the first cell are clearly defined, the consistency of the terminal and the network side's understanding of allowed and prohibited access is ensured, which facilitates the implementation of the protocol.

[0146] Optionally, in some embodiments, the first capability type is determined based on a first parameter, the information of the allowed access cell includes a second parameter, and the information of the prohibited access cell includes a second parameter;

[0147] The first parameter includes at least one of the following:

[0148] Wireless capability information, which includes at least one of the following: bandwidth supported by the terminal, peak data rate, peak power consumption, radio frequency capability, baseband processing capability, transmit power capability, demodulation capability, decoding capability, duplex mode, and energy efficiency constraints.

[0149] Terminal characteristic information, which includes at least one of the following: bandwidth information, coverage information, power consumption information, energy saving information, and terminal type information of the terminal;

[0150] The service characteristic information includes at least one of the following: Small Data Transmission (SDT) service, enhanced Mobile Broadband (eMBB) service, Ultra-Reliable and Low Latency Communications (URLLC) service, extended reality (XR) service, sensing service, and artificial intelligence (AI) / machine learning (ML) service;

[0151] The second parameter includes at least one of the following:

[0152] Wireless capability information, which includes at least one of the following: bandwidth supported by the terminal, peak data rate, peak power consumption, radio frequency capability, baseband processing capability, transmit power capability, demodulation capability, decoding capability, duplex mode, and energy efficiency constraints.

[0153] Terminal characteristic information, which includes at least one of the following: bandwidth information, coverage information, power consumption information, energy saving information, and terminal type information of the terminal;

[0154] Business characteristic information, which includes at least one of the following: SDT business, eMBB business, URLLC business, XR business, perception business, and AI / ML business.

[0155] It should be understood that the second parameter included in the information allowing or prohibiting access to the cell may be the same as or different from the first parameter used to determine the first capability type. For example, the second parameter included in the information allowing or prohibiting access to the cell may include the first parameter used to determine the first capability type.

[0156] In this embodiment, since the terminal's first capability type, the information on allowed access cells, and the information on prohibited access cells are clearly defined, the consistency of understanding between the terminal and the network-side equipment can be ensured, which facilitates implementation.

[0157] Optionally, in some embodiments, determining whether the terminal's access attempt is allowed or denied based on the second parameter configuration includes:

[0158] The access attempt of the terminal is allowed or denied based on the access information used for the terminal access attempt and the second parameter configuration.

[0159] In this embodiment, the aforementioned second parameter configuration can be understood as a UAC parameter configuration, for example, the second parameter configuration can be sent via UAC parameter configuration signaling. This second parameter configuration may include a first access probability and a maximum access denial duration. The first access probability in the second parameter configuration is used to determine whether to allow the terminal's current access attempt. For example, the terminal can predict the access probability of the current access attempt based on information such as signal quality. When the current access probability is greater than the first access probability, it can be determined that the terminal's access attempt is allowed.

[0160] It should be understood that in this application example, the access attempt or denial of the terminal is determined by the access information based on the terminal's access attempt, thereby controlling each access attempt of the terminal and improving the flexibility of terminal access control.

[0161] Optionally, in some embodiments, the second parameter configuration includes at least one of the following:

[0162] At least one set of first unified access control (UAC) parameter configurations, each set of first UAC parameter configurations being associated with a combination of at least one AC value, at least one PLMN identifier, and at least one value of the coverage enhancement level;

[0163] A second set of UAC parameter configurations, which is a common UAC parameter configuration.

[0164] In this embodiment of the application, a set of first UAC parameter configurations may include M1 AC values, M2 PLMN identifiers, and M3 coverage enhancement level values, where M1, M2, and M3 can be positive integers. In different first UAC parameter configurations, at least one parameter may have a different value.

[0165] Optionally, the access information can be matched with the second parameter configuration. If at least one first UAC parameter configuration does not contain a set of first UAC parameter configurations associated with the access information, the access attempt can be considered permitted. If at least one first UAC parameter configuration contains a set of first UAC parameter configurations associated with the access information, the access attempt can be determined as either prohibited or permitted based on this set of first UAC parameter configurations. Here, the association can be understood as follows: the content contained in the first UAC parameter configuration matches the content contained in the access information. For example, the AC value contained in the first UAC parameter configuration is the same as the AC value corresponding to the terminal's AC; the PLMN contained in the first UAC parameter configuration is the same as the PLMN selected by the terminal or the terminal's serving PLMN; and the coverage enhancement level contained in the first UAC parameter configuration is the same as the coverage enhancement level at which the terminal is located.

[0166] Optionally, if the second parameter configuration includes the at least one set of first unified access control (UAC) parameter configurations (i.e., UAC parameter configurations specific to access information) and the second set of second UAC parameter configurations (i.e., common UAC parameter configurations), the terminal ignores the second set of second UAC parameter configurations and applies the at least one set of first unified access control (UAC) parameter configurations therein. In other words, the common UAC parameter configuration can be overridden by the dedicated UAC parameter configuration.

[0167] Optionally, in some embodiments, the second UAC parameter configuration described above can be applied to all values ​​of the first information. For example, if the first information includes the identifier of the PLMN, then when the network-side device sends the second UAC parameter configuration, it can be assumed that the PLMN of the terminal's current access attempt has an associated set of UAC parameter configurations. As another example, if the first information includes an AC, then when the network-side device sends the second UAC parameter configuration, it can be assumed that the AC of the terminal's current access attempt has an associated set of UAC parameter configurations.

[0168] In this embodiment, by adding a value for the coverage enhancement level to the UAC parameter configuration, the existing related UAC parameter configurations do not need to be adjusted; only the content related to the value of the coverage enhancement level needs to be added. This facilitates the adjustment of the UAC parameter configuration for changes in terminal capability types, and enables unified access control for terminals with different capability types.

[0169] Optionally, in some embodiments, the second parameter configuration includes at least one of the following:

[0170] At least one set of third access control (UAC) parameter configurations, each set of said third UAC parameter configurations being associated with a combination of at least one AC value and at least one identifier of said PLMN;

[0171] A fourth UAC parameter configuration, wherein the fourth UAC parameter configuration is a common UAC parameter configuration;

[0172] The AC and the coverage enhancement level are related.

[0173] In this embodiment of the application, a set of third UAC parameter configurations may include N1 AC values ​​and N2 PLMN identifiers, where N1 and N2 can be positive integers. In different third UAC parameter configurations, at least one parameter may have a different value.

[0174] Optionally, if the second parameter configuration includes at least one set of third unified access control (UAC) parameter configurations (i.e., UAC parameter configurations specific to access information) and also includes one set of fourth UAC parameter configurations (i.e., common UAC parameter configurations), the terminal ignores the fourth set of fourth UAC parameter configurations and applies the at least one set of third unified access control (UAC) parameter configurations therein. In other words, the common UAC parameter configuration can be overridden by the dedicated UAC parameter configuration.

[0175] Optionally, in some embodiments, the AC value is determined based on the coverage enhancement level at which the terminal is located; for example, the AC value can be determined based on the terminal's AC and coverage enhancement level.

[0176] Optionally, the original AC value of 3 (without considering coverage) can be extended by defining multiple coverage enhancement levels (CE-level) and mapping them to different coverage levels.

[0177] For example, in some embodiments, two coverage levels, high and low, can be used. The original AC=3 is extended to AC=3 and AC=11, which correspond to high and low coverage levels, respectively.

[0178] For example, in some embodiments, four coverage levels 0, 1, 2, and 3 can be used, and the original AC=3 can be extended to AC=3, AC=11, AC=12, and AC=13, which correspond to coverage levels 0, 1, 2, and 3, respectively.

[0179] For example, in some embodiments, the four coverage levels 0, 1, 2, and 3 are expanded from AC=3 to AC=3, AC=11, and AC=12. Here, AC=3 is mapped to coverage level 0, AC=11 is mapped to the coverage level range {1,2}, and AC=12 is mapped to coverage level 3.

[0180] In this embodiment of the application, the AC value can be jointly determined based on at least one of the following: terminal-side service information (e.g., whether the terminal is configured or authorized with a specific service, such as latency-tolerant service or high-latency communication service, XR service, Sensing service, etc.), terminal access attempt type (e.g., access attempt triggered by paging process, access attempt triggered by emergency service, access attempt initiated by terminal signaling, access attempt initiated by terminal service data, access attempt triggered by short message service, etc.) and coverage enhancement level.

[0181] Optionally, in some embodiments, the access information includes at least one of the following:

[0182] The terminal's AC;

[0183] The PLMN selected by the terminal or the service PLMN of the terminal;

[0184] The coverage enhancement level at which the terminal is located.

[0185] Optionally, in some embodiments, the Radio Resource Control (RRC) layer of the terminal sends the coverage enhancement level of the terminal to the Non-Access Stratum (NAS) layer of the terminal;

[0186] The NAS layer of the terminal sends the AC of the terminal to the RRC layer of the terminal.

[0187] In this embodiment of the application, the interaction behavior of the RRC layer and the NAS layer can be performed by only one of them, or by both of them. The order of execution is not further limited here.

[0188] For example, in one implementation: the terminal's Radio Resource Control (RRC) layer can first send the coverage enhancement level of the terminal to the terminal's Non-Access Stratum (NAS) layer, and then the terminal's NAS layer can send the terminal's AC value to the terminal's RRC layer. At this time, the AC value sent is determined based on the coverage enhancement level received this time.

[0189] In one implementation: the terminal's NAS layer first sends the terminal's AC value to the terminal's RRC layer, and then the terminal's RRC layer sends the coverage enhancement level of the terminal to the terminal's NAS layer. In this case, the sent AC value is determined based on the most recently received coverage enhancement level. The currently received coverage enhancement level will be used to determine the AC value in future access attempts.

[0190] Optionally, in some embodiments, determining whether the terminal's access attempt is allowed or denied based on the access information used for the terminal's access attempt and the second parameter configuration includes at least one of the following:

[0191] If the second parameter configuration does not include a set of UAC parameter configurations associated with the access information, the terminal determines that the terminal's access attempt is permitted;

[0192] When the second parameter configuration includes a set of UAC parameter configurations associated with the access information, the terminal determines whether its access attempt is allowed or denied based on the set of UAC parameter configurations associated with the access information.

[0193] For example, in some embodiments, the second parameter configuration includes two sets of first UAC parameter configurations. One set of UAC parameter configurations includes: AC value = 3, PLMN identifier = 2, coverage enhancement level = 0, first access probability = 0.5, and maximum access prohibition duration = 5 seconds. The other set of UAC parameter configurations includes: AC value = 3, PLMN identifier = 1, coverage enhancement level = 1, first access probability = 0.6, and maximum access prohibition duration = 5 seconds. Assuming the terminal's access attempt information includes AC = 2, PLMN identifier = 1, and coverage enhancement level = 1, then the second parameter configuration does not contain a first UAC parameter configuration matching the terminal's access attempt information. Assuming the terminal's access attempt information includes AC = 3, PLMN identifier = 1, and coverage enhancement level = 1, then the second parameter configuration contains a set of UAC parameter configurations matching the terminal's access attempt information. In this case, the terminal can estimate the access probability based on current signal strength and other parameters. If the access probability is greater than 0.5, the terminal's access attempt can be considered permitted.

[0194] Optionally, in some embodiments, the method further includes at least one of the following:

[0195] If it is determined that the terminal's access attempt is blocked, the terminal starts an access blocking timer;

[0196] If the access prohibition timer is allowed to time out, the terminal determines that the access prohibition has been lifted.

[0197] Optionally, in some embodiments, each bit in the bitmap is used to indicate whether a capability category is allowed or prohibited from accessing the first cell.

[0198] In this embodiment, each bit in the bitmap represents, in bit order, whether a 6G capability category is allowed or prohibited from accessing the first cell. For example, the bitmap is 32 bits long, and the bits are arranged from lowest to highest to represent whether 6G capability categories 0, 1, 2…31 are allowed or prohibited from accessing the first cell. In some embodiments, each bit is '0' to represent allowed and '1' to represent prohibited, or each bit is '1' to represent allowed and '0' to represent prohibited.

[0199] In this embodiment of the application, since each bit in the bitmap is used to indicate whether a capability category is allowed or prohibited from accessing the first cell, the number of bits in the bitmap can be increased when a capability category is added, thereby improving the flexibility of capability category indication and reducing the need for protocol modifications, making it easier to implement.

[0200] Optionally, in some embodiments, the length of the list is variable, and each entry in the list is associated with an index value, which indicates whether a capability category is allowed or prohibited from accessing the first cell.

[0201] In this embodiment, a List can be used, with a maximum length of 32. Each entry in the List is associated with an index value. The specific index value in the List indicates whether a 6G capability category is allowed or prohibited from accessing the first cell. For example, if the List is configured with index = 0, 1, 2, ..., 10, it means that: if the UE's 6G capability category meets any one of the values ​​in index = 0, 1, 2, ..., 10, the UE is allowed to access the first cell; if the UE's 6G capability category is not in the List, the UE is prohibited from accessing the first cell; or, if the UE's 6G capability category is not in the List, the UE is allowed to access the first cell; if the UE's 6G capability category meets any one of the values ​​in index = 0, 1, 2, ..., 10, the UE is prohibited from accessing the first cell.

[0202] In this embodiment of the application, since each entry in the list is associated with an index value to indicate whether a capability category is allowed or prohibited from accessing the first cell, the number of entries in the list can be increased when a capability category is added, thereby improving the flexibility of capability category indication and reducing the need for protocol modifications, making it easier to implement.

[0203] Reference Figure 3 This application also provides an information transmission method, such as... Figure 3 As shown, the information transmission method includes:

[0204] Step 301: The network-side device sends system information of the first cell to the terminal. The system information carries at least one of a first parameter configuration and a second parameter configuration. The first parameter configuration is used to determine whether the first cell is allowed or denied access, and the second parameter configuration is used to determine whether the terminal's access attempt is allowed or denied.

[0205] The first parameter configuration is used to indicate at least one of the information on allowed cell access and information on prohibited cell access via a bitmap or list;

[0206] The second parameter configuration is associated with the first information, which includes the coverage enhancement level.

[0207] Optionally, the first information may also include at least one of the access class AC and PLMN.

[0208] Optionally, the second parameter configuration includes at least one of the following:

[0209] At least one set of first unified access control (UAC) parameter configurations, each set of first UAC parameter configurations being associated with a combination of at least one AC value, at least one PLMN identifier, and at least one coverage enhancement level value;

[0210] A second set of UAC parameter configurations, which is a common UAC parameter configuration.

[0211] Optionally, the second parameter configuration includes at least one of the following:

[0212] At least one set of third access control (UAC) parameter configurations, each set of said third UAC parameter configurations being associated with a combination of at least one AC value and at least one identifier of said PLMN;

[0213] A fourth UAC parameter configuration, wherein the fourth UAC parameter configuration is a common UAC parameter configuration;

[0214] The AC and the coverage enhancement level are related.

[0215] Optionally, each bit in the bitmap is used to indicate whether a capability category is allowed or prohibited from accessing the cell.

[0216] Optionally, the length of the list is variable, and each entry in the list is associated with an index value, which indicates whether a capability category is allowed or prohibited from accessing the cell. The upper limit of the list length is determined by the number of capability categories.

[0217] To better understand this application, some examples are provided below.

[0218] Example 1: Cell barred mechanism adapted to 6G capability category.

[0219] In this embodiment, the Cell barred mechanism needs to adapt to the classification logic of 6G capability categories to achieve a unified Cell barred mechanism for LPWA and eMBB. Another advantage of this design is that the Cell barred parameter configuration broadcast by the cell (i.e., the first parameter configuration) has forward scalability for 6G air interface signaling. Therefore, when more 6G capability categories are introduced in the future, there is no need to enhance the air interface signaling design; only more parameter values ​​need to be broadcast on the air interface.

[0220] For example, defining a classification description for 6G capability categories. Specifically, a 6G capability category includes an index value and a first parameter associated with that index value. The first parameter may consist of at least one of the following:

[0221] Wireless capability information, which includes at least one of the following: bandwidth supported by the terminal, peak data rate, peak power consumption, radio frequency capability, baseband processing capability, transmit power capability, demodulation capability, decoding capability, duplex mode, and energy efficiency constraints.

[0222] Terminal characteristic information, which includes at least one of the following: bandwidth information, coverage information, power consumption information, energy saving information, and terminal type information of the terminal;

[0223] The service characteristic information includes at least one of the following: small data packet service, enhanced mobile broadband service, low latency and high reliability service, extended reality service, sensing service, and artificial intelligence service.

[0224] Optionally, the terminal may obtain its first capability type through at least one of the following methods:

[0225] Method 1: Agreement;

[0226] Method 2: Terminal pre-configuration;

[0227] Method 3: Core network configuration, for example, AMF configures the UE via NAS signaling.

[0228] Optionally, when more than one method is applied on the UE side, the priority order of how these methods are applied can be specified, for example, method 3 takes precedence over method 2 over method 1.

[0229] In this embodiment, the design of the air interface process includes the following steps:

[0230] Step S1: The UE receives the system information SIB1 of the cell, which may or may not carry the Cell barred parameter configuration (i.e., the first parameter configuration), wherein the Cell barred parameter configuration describes whether at least one 6G capability category is allowed or prohibited from accessing the cell.

[0231] Optionally, the Cell barred parameter can be configured as a Bitmap or a List.

[0232] For example, the Cell barred parameter can be configured as a Bitmap. Each bit in the Bitmap represents, in bit order, whether a 6G capability category is allowed or prohibited from accessing the cell. For example, the Bitmap is 32 bits long, and the bits represent 6G capability categories 0, 1, 2...31 in order from lowest to highest. For example, each bit with a value of '0' represents allowed access and '1' represents prohibited access, or each bit with a value of '1' represents allowed access and '0' represents prohibited access.

[0233] For example, the Cell barred parameter can be configured as a List, with a maximum length of 32. Each entry in the List is associated with an index. The specific index value in the List indicates whether a 6G capability category is allowed or prohibited from accessing the cell. For example, if the List is configured with index = 0, 1, 2, ..., 10, it means that: if the UE's 6G capability category meets any of the values ​​in index = 0, 1, 2, ..., 10, the UE is allowed to access the cell; if the UE's 6G capability category is not in the List, the UE is prohibited from accessing the cell; or, if the UE's 6G capability category is not in the List, the UE is allowed to access the cell; if the UE's 6G capability category meets any of the values ​​in index = 0, 1, 2, ..., 10, the UE is prohibited from accessing the cell.

[0234] Step S2a: If SIB1 does not carry Cell barred parameter configuration, the UE considers itself allowed to access the cell.

[0235] Step S2b: If SIB1 carries the Cell barred parameter configuration, the UE determines whether it is allowed to access the cell (Cell not barred) based on one of the following:

[0236] The UE's capability category appears in the Cell barred parameter configuration, and the Cell barred parameter configuration describes at least one UE's capability category that is allowed to access;

[0237] The UE's capability category does not appear in the Cell barred parameter configuration, and the Cell barred parameter configuration describes that at least one UE's capability category is prohibited from access;

[0238] Alternatively, the UE may determine that it is barred from accessing the cell based on one of the following:

[0239] The UE's capability category appears in the Cell barred parameter configuration, and the Cell barred parameter configuration describes that at least one UE's capability category is prohibited from access;

[0240] The UE's capability category does not appear in the Cell barred parameter configuration, and the Cell barred parameter configuration describes at least one UE's capability category as being allowed access.

[0241] Building upon step 2b, when the number of capability categories configured for the UE exceeds one, one of the following methods is defined:

[0242] The UE determines access based on the lowest-level capability category. If the capability category is not cell-barred, access is considered permitted; otherwise, access is considered prohibited.

[0243] The UE determines access based on the highest-level capability category. If the capability category is not cell-barred, access is considered permitted; otherwise, access is considered prohibited.

[0244] The UE randomly selects a capability category for judgment. If the capability category is not barred by the cell, access is considered allowed; if the capability category is barred by the cell, access is considered prohibited.

[0245] The UE judges each capability category one by one. If any capability category is not cell-barred, access is considered allowed; if all capability categories are cell-barred, access is considered prohibited.

[0246] The UE judges each capability category one by one. If any capability category is cell-barred, access is considered prohibited; if none of the capability categories are cell-barred, access is considered allowed.

[0247] If the UE determines that it is allowed to access the cell and initiates an access attempt, it can further execute the UAC mechanism (i.e., Example 2).

[0248] It should be noted that Implementation Example 2 can be executed independently, based on the Cellbarred mechanism which does not need to be adapted to the 6G capability category, and directly execute the UAC mechanism.

[0249] Example 2: UAC mechanism based on coverage enhancement.

[0250] In this embodiment, the access probability and / or the duration of access denial for the terminal are controlled based on different coverage areas (i.e., coverage enhancement level, CE level), thereby implementing a UAC mechanism for LPWA and eMBB. For example, compared to a terminal in the first coverage level (RSRP1 measured by the UE) and a terminal in the second coverage level (RSRP2 measured by the UE), if RSRP1 is higher than RSRP2, the terminal in the first coverage level will enjoy a higher access probability and / or a shorter access denial duration. This embodiment has two methods:

[0251] Method 1: Enhance SIB1 UAC parameter configuration signaling by introducing a new dimension: per AC, per PLMN, and per CE level (i.e., using AC, PLMN, and CE level as granularities) to associate a set of UAC parameter configurations. The terminal determines which UAC parameter configuration to use for access based on its current CE level. This includes the following steps:

[0252] Step S11: The UE receives SIB1 of the cell, wherein SIB1 carries or does not carry UAC parameter configuration, wherein the UAC parameter configuration (i.e., the second parameter configuration) describes the UAC parameter configuration for access control based on at least one of AC, PLMN, and CE-level. Specifically, it includes at least one of the following configuration methods:

[0253] At least one set of UAC parameter configurations (i.e., the first UAC parameter configuration), wherein each set of UAC parameter configurations is associated with at least one AC value, at least one PLMN identifier and at least one CE-level value;

[0254] A set of UAC parameter configurations (i.e., the second UAC parameter configuration), wherein the set of UAC parameter configurations is shared by at least one of any AC value, any PLMN value, and any CE-level value.

[0255] Each UAC parameter configuration includes at least the probability of access and the maximum duration of access restriction.

[0256] Step S12, the UE obtains access information related to this access attempt, including at least one of the following:

[0257] The UE's access class AC, wherein the AC is provided to the UE's AS layer by the UE's NAS layer, or is determined by the UE's AS layer itself;

[0258] The PLMN selected by the UE or the PLMN provided by the UE's NAS layer to the UE's AS layer;

[0259] The coverage enhancement level (CE-level) of the UE. The CE-level is determined by the UE by measuring the RSRP value of the Uu radio interface. For example, there is a one-to-one correspondence between a Uu RSRP value range and a CE-level value. This correspondence is broadcast through the cell's SIB1. The UE determines its CE-level based on its measured Uu RSRP value and the correspondence broadcast by SIB1.

[0260] Step S12a: If the SIB1 does not carry UAC parameter configuration, the UE considers this access attempt to be allowed.

[0261] Step S12b: If the SIB1 carries UAC parameter configuration, the UE determines whether there is a set of UAC parameter configuration associated with the access information based on the access information related to this access attempt (i.e., at least one of AC, PLMN and CE-level) and the UAC parameter configuration.

[0262] Optionally, if there is no set of UAC parameter configurations associated with the access information, the UE considers the access attempt to be permitted.

[0263] Optionally, if there is a set of UAC parameter configurations associated with the access information, the UE determines whether the corresponding access attempt is prohibited or allowed based on this set of UAC parameter configurations. If it is prohibited, the corresponding access prohibition timer is started. If the access prohibition timer times out, the access prohibition is considered to be lifted (i.e., a new access attempt is allowed).

[0264] Method 2: Without changing the existing SIB1 UAC parameter configuration signaling (one set of UAC parameter configurations per AC per PLMN), more AC values ​​are introduced and mapped to different CE-levels. The terminal determines which set of UAC parameter configurations to use for access based on its current CE-level. Specific steps are described below:

[0265] Step S21: The UE receives SIB1 of the cell, wherein SIB1 carries or does not carry UAC parameter configuration (i.e., second parameter configuration), wherein the UAC parameter configuration describes the UAC parameter configuration for access control based on at least one of AC and PLMN. Specifically, it includes at least one of the following configuration methods:

[0266] At least one set of UAC parameter configurations (i.e., the third UAC parameter configuration), wherein each set of UAC parameter configurations is associated with at least one AC value and at least one PLMN identifier combination;

[0267] A set of UAC parameter configurations (i.e., the fourth UAC parameter configuration), wherein this set of UAC parameter configurations is shared by at least one of any AC and any PLMN.

[0268] Step S22: The UE obtains access information related to this access attempt, including at least one of the following:

[0269] The UE's Access Class (AC) is provided by the UE's NAS layer to the UE's AS layer, or determined by the UE's AS layer itself. The AC value is determined with reference to the UE's Coverage Enhancement Level (CE-level). For example, if the original AC value is 3 (regardless of coverage), due to the introduction of multiple Coverage Enhancement Levels (CE-levels), the original AC value can be extended and mapped to different coverage levels. Example 1: With two coverage levels, high and low, the original AC=3 is extended to AC=3 and AC=11, corresponding to high and low coverage levels respectively. Example 2: With four coverage levels, 0, 1, 2, and 3, the original AC=3 is extended to AC=3, AC=11, AC=12, and AC=13, corresponding to coverage levels 0, 1, 2, and 3 respectively. Example 3: With four coverage levels, 0, 1, 2, and 3, the original AC=3 is extended to AC=3, AC=11, and AC=12. AC=3 maps to coverage level 0, AC=11 maps to the coverage level range {1,2}, and AC=12 maps to coverage level 3.

[0270] The PLMN selected by the UE or the PLMN served, wherein the PLMN is provided to the UE's AS layer by the UE's NAS layer.

[0271] Optionally, before step S21, the UE indicates its current coverage enhancement level (CE-level) to its NAS layer. The CE-level is determined by the RSRP value measured by the UE. For example, there is a one-to-one correspondence between an RSRP range and a CE-level value, and this correspondence is broadcast via the cell's SIB1. The UE determines its current CE-level based on its measured RSRP value and this correspondence broadcast by SIB1. If the UE's current coverage enhancement level (CE-level) has changed since the last indication to the UE's NAS layer, the UE indicates the changed coverage enhancement level (CE-level) again to its NAS layer. That is, the UE ensures that it always indicates the latest coverage enhancement level (CE-level) to its NAS layer.

[0272] Step S23a: If SIB1 does not carry UAC parameter configuration, the UE considers this access attempt to be allowed.

[0273] Step S23b: If the SIB1 carries UAC parameter configuration, the UE determines whether there is a set of UAC parameter configuration associated with the access information based on the access information related to this access attempt (i.e., at least one of AC, PLMN and CE-level) and the UAC parameter configuration.

[0274] Optionally, if there is no set of UAC parameter configurations associated with the access information, the UE considers the access attempt to be permitted.

[0275] Optionally, if there is a set of UAC parameter configurations associated with the access information, the UE determines whether the corresponding access attempt is prohibited or allowed based on this set of UAC parameter configurations. If it is prohibited, the corresponding access prohibition timer is started. If the access prohibition timer times out, the access prohibition is considered to be lifted (i.e., a new access attempt is allowed).

[0276] In the design of future communication systems (such as 6G), this application introduces a unified access control mechanism for LPWA and eMBB design to meet the UAC mechanism adapted to 6G capability categories and coverage enhancement. This mechanism prioritizes eMBB UE access while taking into account access fairness.
