[0024] Figure 1 A schematic diagram of an example communication network 100 in which embodiments of the present disclosure may be implemented is illustrated. Figure 1 As shown, the communication network 100 may include terminal equipment 110, network equipment 120 and core network (CN) 130.

[0025] In some embodiments, communication in communication network 100 may include integrated sensing and communication. In other words, communication network 100 may support wireless sensing functionality. Hereinafter, the term "wireless sensing functionality" is also referred to as "wireless sensing," "wireless sensing technology," "sensing and communication," "radio sensing," or integrated sensing and communication.

[0026] The wireless sensing-enabled communication network 100 can be built with a shared hardware architecture, channel characteristics, and signal processing, and integrate various sensing information, such as sensing data from the environment and radar-based sensing information, as well as communication information, to achieve higher resource efficiency and provide a more intelligent and integrated network solution. The wireless sensing-enabled communication network 100 can be applied to a wider range of scenarios, including smart homes, smart manufacturing, and environmental monitoring.

[0027] To support wireless sensing, terminal device 110 may be communicatively coupled to at least one module, entity, or layer 112 associated with wireless sensing functionality.

[0028] In some embodiments, examples of wireless sensing capabilities may include, but are not limited to: healthcare capabilities, smart home capabilities, blood pressure monitoring, heart rate monitoring, air conditioning control, smart factory capabilities, and smart transportation capabilities.

[0029] In some embodiments, at least one module, entity, or layer 112 may be integrated into the terminal device 110. Alternatively, at least one module, entity, or layer 112 may be physically separated from the terminal device 110.

[0030] In some embodiments, the terminal device 110 supporting wireless sensing may be an updated terminal device with wireless sensing capabilities. In such embodiments, the wireless sensing capability may be implemented without adding new modules. Only the wireless sensing capability is added to a traditional terminal device. In such embodiments, at least one module, entity, or layer 112 may be at least one existing module, entity, or layer in the terminal device. For example, at least one module, entity, or layer 112 may be an existing MAC entity or an existing RRC layer.

[0031] In some embodiments, at least one module, entity, or layer 112 may be at least one new module, entity, or layer.

[0032] Alternatively, in some embodiments, terminal device 110 may be a new, specific-function device dedicated to sensing and communication. The scope of this disclosure is not limited in this respect.

[0033] Similarly, to support wireless sensing capabilities, network device 120 can be communicatively coupled to at least one module, entity, or layer 122. For example, network device 120 can be implemented as a gNB in ​​an NR that supports wireless sensing capabilities.

[0034] In some embodiments, CN 130 may be implemented as a sensing-related CN or an updated CN that supports wireless sensing capabilities.

[0035] In some embodiments, CN 130 may include a node or device that supports wireless sensing capabilities. For example, CN 130 may include an updated Access and Mobility Management (AMF) function that supports wireless sensing capabilities.

[0036] Communication in communication network 100 can conform to any suitable standard, including but not limited to Global System for Mobile Communications (GSM), LTE, LTE Evolution, LTE-A Advanced, Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access (CDMA), GSMEDGE Radio Access Network (GERAN), Machine Type Communication (MTC), etc. Furthermore, communication can be performed according to any generation of communication protocols currently known or to be developed in the future. Examples of communication protocols include, but are not limited to, first-generation (1G), second-generation (2G), 2.5G, 2.75G, third-generation (3G), fourth-generation (4G), 4.5G, fifth-generation (5G), and sixth-generation (6G) communication protocols.

[0037] It should be understood that Figure 1 The number of devices given is for illustrative purposes only and does not constitute any limitation on this disclosure. The communication network 100 may include any suitable number of devices appropriate for implementing embodiments of this disclosure.

[0038] In NR, for access requests triggered by the Non-Access Stratum (NAS) layer of an end device, the NAS layer determines the access category and access identifier(s). Considering the potential architecture with a sensing-related CN or an updated CN or AMF supporting wireless sensing capabilities or devices, wireless sensing-related access attempts may not be triggered by the NAS layer.

[0039] Furthermore, in the traditional context, Next Generation Radio Access Networks (NG-RAN) support overload and access control functions such as Random Access Channel (RACH) backoff, Radio Resource Control (RRC) connection rejection, RRC connection release, and UE-based access prohibition mechanisms. To enable terminal devices to access networks that support wireless sensing, access control procedures should be considered.

[0040] Traditionally, Access Class 3 is used to indicate that an access attempt is for Mobile Origin (MO) signaling, and Access Class 7 is used to indicate that an access attempt is for MO data. If Access Class 3 or Access Class 7 is reused, it becomes impossible to distinguish sensing and communication messages from traditional MO signaling or MO data. When wireless sensing technology is applied in special cases such as healthcare, the data signaling used for wireless sensing functions can be more important and urgent. Therefore, it is best to distinguish this data or signaling from traditional MO signaling or MO data.

[0041] In view of the above, embodiments of this disclosure provide a communication solution. In this solution, a terminal device receives indication information from a network device. Then, the terminal device determines the access control status of the terminal device based on the indication information. The access control is associated with a wireless sensing function supported by the terminal device. In this way, controlled access of a terminal device supporting wireless sensing functionality can be achieved.

[0042] The following will refer to Figures 2 to 5 The principles of this disclosure are described.

[0043] Figure 2 A signaling diagram of an example process 200 for communication according to some embodiments of the present disclosure is illustrated. Reference will be made to this diagram for discussion purposes. Figure 1 Describe process 200. Process 200 may involve terminal device 110 and second network device 120.

[0044] like Figure 2 As shown, the second network device 120 sends instruction information 210 to the terminal device 110. Therefore, the terminal device 110 receives instruction information from the second network device 120.

[0045] In some embodiments, the second network device 120 may broadcast system information, and the system information may include indication information.

[0046] In some embodiments, data or signaling associated with the wireless sensing function arrives at 220.

[0047] Next, a 230 access attempt was triggered.

[0048] In some embodiments, the access attempt may be triggered by at least one module, entity, or layer 112. In such embodiments, at least one module, entity, or layer 112 may determine information related to access control. The information related to access control may be associated with a first set of access control parameters for wireless sensing functionality. Then, at least one module, entity, or layer 112 may provide the access control related information to the access layer (AS) of the terminal device 110.

[0049] Alternatively, in some embodiments, the access attempt may be initiated by at least one module, entity, or layer 112. In such embodiments, at least one module, entity, or layer 112 may determine information related to access control. Furthermore, at least one module, entity, or layer 112 may provide the access control-related information to the NAS layer of the terminal device 110. Subsequently, the NAS layer of the terminal device 110 may trigger an access attempt and provide the access control-related information to the terminal device 110.

[0050] Continue to refer to Figure 2 Terminal device 110 determines the access control status of terminal device 110 based on indication information. Access control is associated with wireless sensing functions supported by terminal device 110.

[0051] In some embodiments, the state of access control may include: access attempt is allowed or access attempt is not allowed. In other words, by determining the state of access control of terminal device 110, terminal device 110 can determine whether the access attempt is allowed or not.

[0052] In some embodiments, the AS layer of terminal device 110 may determine the access control status of terminal device 110 based on indication information.

[0053] In some embodiments, the indication information may include a list of access control parameter sets, and the list may include a first access control parameter set for wireless sensing functions.

[0054] In some embodiments, the terminal device 110 may, for example, receive UAC-BarringInfoSetList Information elements (IEs) are used to receive indication information from network device 120. A list of access control parameter sets can be included in the indication information, for example, as included in... UAC-BarringInfoSetList In Internet Explorer, an access class with access parameters can be accepted based on a set of access control parameters in the access control parameter set. For example, UAC-BarringInfoSetList IE can be defined as follows: UAC-BarringInfoSetList ::= SEQUENCE (SIZE(1..maxBarringInfoSet)) OFUAC-BarringInfoSet UAC-BarringInfoSet ::= SEQUENCE { uac-BarringFactor ENUMERATED {p00, p05, p10, p15,p20, p25, p30, p40, p50, p60, p70, p75, p80, p85, p90, p95}, uac-BarringTime ENUMERATED {s4, s8, s16, s32, s64,s128, s256, s512}, uac-BarringForAccessIdentity BIT STRING (SIZE(7)) } "UAC-BarringInfoSetList" indicates UAC-BarringInfoSetList In Internet Explorer, “UAC-BarringInfoSet” represents the set of access control parameters used for an access class.

[0055] Table 1 provides the following information: UAC-BarringInfoSetList IE field descriptions. Table 1

[0056] In some embodiments, the list of access control parameter sets may include a first access control parameter set for wireless sensing functionality.

[0057] As mentioned above, examples of wireless sensing functions may include, but are not limited to: healthcare functions, smart home functions, blood pressure functions, heart rate functions, and air conditioning control functions.

[0058] In some embodiments, the list of access control parameter sets may include an access control parameter set for each of the wireless sensing functions described above. For example, the list of access control parameter sets may include an access control parameter set for healthcare functions, an access control parameter set for smart home functions, etc.

[0059] As referenced above Figure 2 At least one module, entity, or layer 112 may determine information related to access control. At least one module, entity, or layer 112 may be at least one new module, entity, or layer. Alternatively, at least one module, entity, or layer 112 may be at least one existing module, entity, or layer. In some embodiments, the information related to access control may include at least one of the following: an access category for wireless sensing functions, or an access identifier for wireless sensing functions.

[0060] In some embodiments, information related to access control may be associated with a first set of access control parameters for wireless sensing functions. Therefore, terminal device 110 may use the first set of access control parameters for wireless sensing functions based on the information related to access control. For example, terminal device 110 may determine the first set of access control parameters for wireless sensing functions based on the access category for wireless sensing functions. In other words, terminal device 110 may select the first set of access control parameters from a list of access control parameter sets based on the access category for wireless sensing functions.

[0061] In some embodiments, terminal device 110 may receive from network device 120 association information between access category and first access control parameter set for wireless sensing function.

[0062] In some embodiments, terminal device 110 can receive data from network device 120. UAC- BarringPerCat IE receives the associated information. For example, UAC-BarringPerCat IE can be defined as follows: UAC-BarringPerCat ::= SEQUENCE { accessCategory INTEGER (1..maxAccessCat-1), uac-barringInfoSetIndex UAC-BarringInfoSetIndex } Where "UAC-BarringPerCat" represents the access control parameters used for the access category indicated by the field "accessCategory", where "accessCategory" represents the access category, and "uac-barringInfoSetIndex" represents... uac- BarringInfoSetList Index of access control parameter sets in IE.

[0063] In some embodiments, the access category may include a dedicated access category for wireless sensing functionality. Alternatively, the access identifier may include a dedicated access identifier for wireless sensing functionality, which will be described later with reference to Table 3.

[0064] In such an embodiment, Table 2 provides an example of a mapping table for access categories: Table 2

[0065] As shown in Table 2, a dedicated access category (i.e., 8) is defined for the wireless sensing function. In such an embodiment, the field "accessCategory" in the "UAC-BarringPerCat" IE can be set to "8" so that the "UAC-BarringPerCat" IE is associated with the wireless sensing function. Therefore, "uac-barringInfoSetIndex" indicates... uac- BarringInfoSetList The index of the first access control parameter set associated with the wireless sensing function in IE.

[0066] It should be noted that the Private Access Class is described using "8" as an example. In other embodiments, the Private Access Class can be defined as any suitable value. The scope of this disclosure is not limited in this respect.

[0067] In embodiments where terminal device 110 supports more than one wireless sensing function, a dedicated access class can be defined for each wireless sensing function. For example, a dedicated access class (such as 8) can be defined for the healthcare function, and another dedicated access class (such as 9) can be defined for the smart home function, etc.

[0068] Alternatively, a dedicated access class can be defined for all wireless sensing functions within the wireless sensing functionality.

[0069] In some embodiments, a traditional access class can be defined for a wireless sensing function or all wireless sensing functions within a wireless sensing function. In such embodiments, this can be achieved by adding... uac-BarringInfoSetList A new index for the first access control parameter set associated with wireless sensing functionality in IE is used to update... UAC-BarringPerCat IE. For example, the updated version UAC-BarringPerCat IE can be defined as follows: UAC-BarringPerCat ::= SEQUENCE { accessCategory INTEGER (1..maxAccessCat-1), uac-barringInfoSetIndex UAC-BarringInfoSetIndex uac-barringInfoSetIndex-sensing-F1 UAC-BarringInfoSetIndex } The "uac-barringInfoSetIndex-sensing-F1" indicates uac-BarringInfoSetListThe index of the first access control parameter set in IE. The first access control parameter set is associated with the wireless sensing function.

[0070] Alternatively, in some embodiments, a conventional UAC-BarringPerCat IE can be used. In other words, UAC- BarringPerCat IE does not include the field "uac-barringInfoSetIndex-sensing-F1". In such an embodiment, the first access control parameter set includes at least one dedicated access control parameter for wireless sensing functionality. For example, the above... UAC-BarringInfoSet IE can be updated by adding at least one dedicated access control parameter for wireless sensing functionality. For example, the updated... UAC-BarringInfoSet IE can be defined as follows: UAC-BarringInfoSet ::= SEQUENCE { uac-BarringFactor ENUMERATED {p00, p05, p10, p15,p20, p25, p30, p40, p50, p60, p70, p75, p80, p85, p90, p95}, uac-BarringTime ENUMERATED {s4, s8, s16, s32, s64,s128, s256, s512}, uac-BarringForAccessIdentity BIT STRING (SIZE(7)) uac-BarringFactor-sensing-F1 ENUMERATED {p00, p05, p10, p15, p20,p25, p30, p40, p50, p60, p70, p75, p80, p85, p90, p95}, uac-BarringTime-sensing-F1 ENUMERATED {s4, s8, s16, s32,s64, s128, s256, s512}, uac-BarringForAccessIdentity-sensing-F1 BIT STRING (SIZE(7)) }

[0071] Table 3 provides the following information: UAC-BarringInfoSetList Description of the newly added field in IE. Table 3

[0072] In some embodiments, the indication information received from network device 120 may include at least one of the following: a cell prohibition indication, or a dedicated cell prohibition indication for wireless sensing functions. Hereinafter, the cell prohibition indication is also referred to as a conventional cell prohibition indication.

[0073] In such an embodiment, the terminal device 110 can receive indication information, such as a master information block (MIB) or a system information block (SIB, such as SIB1 and / or SIB2 and / or other SIBs and / or newly added (multiple) SIBs, by receiving system information.

[0074] In some embodiments, a conventional terminal device that does not support wireless sensing can determine the access control status based on a conventional cell prohibition indication. A terminal device 110 that supports wireless sensing can ignore the conventional cell prohibition indication. In other words, the terminal device 110 can determine the access control status solely based on a dedicated cell prohibition indication.

[0075] For example, a conventional cell prohibition indicator can be set to "prohibited" to indicate that the first cell is prohibited, while a dedicated cell prohibition indicator can be set to "not prohibited" to indicate that the first cell is not prohibited. A conventional terminal device can determine that it is not permitted to select, reselect, or access the first cell. A terminal device 110 supporting wireless sensing can determine that it is permitted to select, reselect, or access the first cell.

[0076] In some embodiments, the dedicated cell prohibition indicator can function when the conventional cell prohibition indicator is set to "prohibited". For example, if the cell prohibition indicator indicates that the first cell is not prohibited, the terminal device 110 may not detect the dedicated cell prohibition indicator. If the cell prohibition indicator indicates that the first cell is prohibited, the terminal device 110 can detect the dedicated cell prohibition indicator to determine a first state of access control for the first cell based on the dedicated cell prohibition indicator.

[0077] Alternatively, in some embodiments, a dedicated cell prohibition indicator can function when the conventional cell prohibition indicator is set to "not prohibited". For example, if the cell prohibition indicator indicates that the first cell is not prohibited, the terminal device 110 can detect the dedicated cell prohibition indicator to determine a first state for access control of the first cell based on the dedicated cell prohibition indicator.

[0078] In some embodiments, the indication information received from network device 120 may further include at least one of the following: a cell selection indication indicating whether selection or reselection of cells within the frequency range is permitted, or a dedicated cell selection indication for wireless sensing functions indicating whether selection or reselection of cells within the frequency range is permitted. Hereinafter, the cell selection indication may be referred to as a conventional cell selection indication, and is defined by... intraFreqReselection Indicated. The dedicated cell selection indicator can be provided by... intraFreqReselection-sensing-F1 It means that among them F1 This indicates wireless sensing functionality.

[0079] In some embodiments, if a conventional cell block indication indicates that the first cell is blocked, the terminal device 110 with wireless sensing capabilities can ignore this. intraFreqReselection Or believe intraFreqReselection It is set to "Allow".

[0080] For example, if a traditional cell prohibition indicator specifies that cell number one is prohibited, and intraFreqReselection If set to "disallowed" to indicate that selection or reselection of the second cell is not allowed, terminal device 110 can ignore it. intraFreqReselection Or believe intraFreqReselection It is set to "Allow".

[0081] In some embodiments, if a conventional cell block indication indicates that the first cell is blocked, the terminal device 110 with wireless sensing capabilities can determine the second state of access control for the second cell based solely on a dedicated cell selection indication. The second cell is located on the same frequency as the first cell. In such an embodiment, the terminal device 110 can ignore... intraFreqReselection .

[0082] In some embodiments, terminal device 110 may send an instruction on wireless sensing functionality to network device 120.

[0083] In some embodiments, the indication of wireless sensing functionality may indicate that terminal device 110 is a new specific function terminal device.

[0084] In some embodiments, terminal device 110 may send uplink messages associated with a random access procedure. The uplink messages may include indications of wireless sensing capabilities. For example, the uplink messages may include at least one of the following: Msg1, Msg3, MsgA Physical Uplink Shared Channel (PUSCH), or MsgA Physical Random Access Channel (PRACH).

[0085] In some embodiments, when a random access procedure is initiated, terminal device 110 may select a random access (RA) resource set and initialize one or more parameters for the random access procedure according to the values ​​configured by RRC for the selected random access resource set.

[0086] For example, terminal device 110 can initialize " prach-ConfigurationIndex ", which indicates the set of available PRACH timings for the transmission of the random access preamble for Msg1. If the PRACH timings are shared between the 2-step type and the 4-step RA type, these also apply to MSGA PRACH.

[0087] In some embodiments, for each MSGA, the MAC entity of terminal device 110 may instruct the physical layer of terminal device 110 to send the MSGA using the selected PRACH timing and the associated PUSCH resources of the MSGA.

[0088] In some embodiments, if the uplink message includes Msg3 or MsgA on the PUSCH, the uplink message may include a dedicated Media Access Control (MAC CE) element, which may include an indication of a wireless sensing function. For example, one or more wireless sensing functions supported by terminal device 110 may be indicated in a bitmap within the MAC CE. Alternatively, one or more wireless sensing functions supported by terminal device 110 may be explicitly indicated in the MAC CE and / or the corresponding Logical Channel ID (LCID).

[0089] In some embodiments, network device 120 may configure at least one dedicated RACH resource for wireless sensing functions, function-specific terminals, or function-specific terminals supporting different wireless sensing functions.
