[0002] Wireless communication technology is driving the world toward an increasingly interconnected and networked society. In recent years, the Internet of Things (IoT) has garnered significant attention in the field of wireless communication. The expectation is for more interconnected "things" to improve productivity and increase the comfort of life. Further reducing the size, complexity, and power consumption of IoT devices could enable the deployment of hundreds of billions or even trillions of IoT devices across a wide range of applications, adding value throughout the value chain. However, powering all IoT devices with batteries that require regular and / or manual replacement or charging is quite challenging, leading to high maintenance costs, serious environmental problems, and even security risks in some use cases, such as wireless sensors in the power and oil industries.
[0003] Some Ambient Internet of Things (AIoT) user equipment (UEs) may be battery-free devices (without energy storage capacity) or devices with limited energy storage that do not require periodic and / or manual replacement or charging. Several issues / challenges exist related to AIoT UEs. One issue / challenges might include how to efficiently determine paging IDs for a single AIoT UE or a group of AIoT UEs. Another issue / challenges might include how to efficiently page a large number of AIoT UEs when they need to be paged. Yet another issue / challenges might include how to determine paging resources for a single IoT UE or a group of AIoT UEs.
[0004] This disclosure describes various embodiments of an AIoT UE performing a mobility termination (MT) procedure, which solves at least one of the problems / challenges mentioned above, and provides improvements in the field of wireless communication technology and enhances its efficiency and performance. Summary of the Invention
[0005] This document relates to methods, systems, and apparatuses for wireless communication, and more specifically, to methods, systems, and apparatuses for performing Mobile-Terminated (MT) procedures on Ambient Internet of Things (AIoT) user equipment (UE). Various embodiments in this disclosure can improve resource utilization efficiency, enhance coverage, and / or improve the throughput and / or reliability of UE transmissions.
[0006] In one embodiment, this disclosure describes a method for wireless communication. The method includes: an Ambient Internet of Things (AIoT) User Equipment (UE) receiving a first paging message from a base station, wherein the first paging message includes at least one of the following: a complete logical AIoT UE identifier (ID), a first partial logical AIoT UE ID, a first mask number of bits or a number of bits for the logical AIoT UE ID, a first mask code for the logical AIoT UE ID, a paging destination indication, a number of paging subgroups, a paging subgroup ID, a paging area code, or a paging cell identifier; based on the first paging message, the AIoT UE determining whether it has been paged; and in response to determining that the AIoT UE has been paged, the AIoT UE performing an action corresponding to the paging destination indication.
[0007] In another embodiment, this disclosure describes a method for wireless communication.

[0019] This disclosure describes a method and apparatus for an environmental Internet of Things (AIoT) user equipment (UE) to perform a mobility termination (MT) process.
[0020] In recent years, the Internet of Things (IoT) has attracted widespread attention in the field of wireless communication. It is anticipated that more "things" will be interconnected to improve productivity and increase the comfort of life. Further reducing the size, complexity, and power consumption of IoT devices could enable the deployment of hundreds of billions or even trillions of IoT devices for a wide range of applications, adding value throughout the value chain. However, powering all IoT devices with batteries that require regular and / or manual replacement or charging is quite challenging, leading to high maintenance costs, serious environmental problems, and even security risks in some use cases, such as wireless sensors in the power and oil industries.
[0021] In some implementations, most existing wireless communication devices are powered by batteries that require manual replacement or charging. Automation and digitalization across various industries have opened up numerous new markets that demand new IoT technologies to support battery-free devices with no energy storage capabilities or energy storage devices that do not require manual replacement or charging. Such devices must be relatively small in size to reflect the effectiveness of the target use case.
[0022] In some implementations, considering the limited size and complexity required for practical applications with battery-less devices lacking energy storage capacity or with limited energy storage that does not require manual replacement or charging, the output power of energy harvesters is typically from 1 µW to several hundred µW. Some existing cellular devices, with peak power consumption exceeding 10 mW, may not work well with energy harvesting. Some existing barcode and / or radio frequency identification (RFID) devices have low power consumption, but their limited reading range of a few meters often requires handheld scanning, leading to labor-intensive and time-consuming operations, or requires RFID entry / exit gates, resulting in high deployment costs. Furthermore, the lack of interference management schemes can lead to severe interference and capacity issues between RFID readers, especially in dense deployments. Therefore, for some IoT devices (e.g., RFID), it may be difficult to support large-scale networks with seamless coverage.
[0023] In some implementations, ambient-powered IoT can be used to address at least one of the aforementioned difficulties / problems; and some issues / challenges related to ambient IoT UEs include, for example, how to efficiently determine a paging ID for a single AIoT UE or a group of AIoT UEs; how to efficiently page a large number of AIoT UEs when paging is required; and / or how to determine paging resources for a single IoT UE or a group of AIoT UEs.
[0024] This disclosure describes various embodiments for performing a mobility termination (MT) procedure on an AIoT UE, which solves at least one of the problems / challenges mentioned above, and provides improvements in the field of wireless communication technology and enhances its efficiency and performance.

The IMEI or EPC may not include location information (e.g., Mobility Management Entity Code (MMEC) and Access and Mobility Management Function (AMF) identifiers), which is inconvenient for the network to locate the registration node of a roaming UE. 3. For AIoT UEs, both UE-specific paging (e.g., checking the status of a UE or changing its configuration) and group paging (e.g., triggering group inventory or triggering multiple UEs to report their status) are necessary; however, the IMEI or EPC is not suitable for group paging.
[0059] In some embodiments, to solve at least one of the above problems / difficulties, a logical UE identifier (e.g., TAG ID and / or Temporary Mobile Subscriber Identity (TMSI)) can be assigned to each AIoT UE (e.g., user TAG). The logical UE ID can consist of at least one of the following information. 1. The core network node identifier registered by the UE, such as the MMEC or AMF identifier. 2. The user code, assigned or authorized by the operator, used to identify the user to which the UE or user tag belongs (e.g., a user or a company, etc.). 3. The device code, assigned or authorized to identify the user's device. 4. The 5G Short-Temporary Mobile Subscription Identifier (5G-S-TMSI) part and the device code part, where the 5G-S-TMSI is the NAS identifier of the user and the device code is used to identify the user's device. For the same type of UE usage, the same core network node identifier, the same user code, and / or the same 5G-S-TMSI, the device code is usually encoded by a consecutive serial number.
[0060] In some embodiments, the structure of the logical UE identifier can be as follows: <MMEC or AMF identifier><user code><device code> or <5G-S-TMSI><device code>. As a non-limiting example, when MMEC = 1001, user code = 234567, and device code = 80001, the logical UE ID is: 100123456780001.
[0061] In some embodiments, the logical AIoT UE identifier can be assigned by the operator and / or the user when the UE or TAG is activated (e.g., written and stored in the UE or USIM) or when the UE registers to the core network (e.g., through the registration process, attachment process, etc.). In some embodiments, the logical AIoT UE ID can be updated by the operator and / or the user, or the logical AIoT UE ID can be triggered by the UE mobility through TAU (Tracking Area Update), LAC (Location Area Update process, etc.). In some embodiments, the logical AIoT UE ID can be used for UE-specific paging, UE group paging, and / or UE identification in the initial access process (e.g., in the contention-based access process).
[0062] In some embodiments, when paging a specific UE, the complete logical AIoT UE identifier may be included in the paging message to identify the UE. As a non-limiting example, when paging a specific AIoT UE with MMEC = 1001, user code = 234567, and device code = 80001, its complete logical AIoT UE identifier (100123456780001) is included in the paging message from the RAN to one or more AIoT UEs including the specific AIoT UE. The paging message may be a paging from the CN to the RAN, or a paging from the RAN to the UE.
[0063] In some embodiments, when paging a group of UEs, partial bits or partial digits of the logical AIoT UE identifier may be included in the paging message to identify the group of UEs. When paging all UEs of a user, only <MMEC or AMF identifier><user code> or <5G-S-TMSI> is included in the paging message to identify all UEs of the user. When paging some UEs of a user, <MMEC or AMF identifier><user code><partial bits or partial digits of the device code> or <5G-S-TMSI><partial bits or partial digits of the device code> may be included in the paging message to identify the paged UEs of the user. The paging message may be a paging from the CN to the RAN, or a paging from the RAN to the UE.
[0064] In some embodiments, when the RAN and / or UE receives the logical AIoT UE identifier in the paging message, it matches the received logical UE identifier with its own stored logical UE identifier to determine whether it is paged. When the RAN and / or UE receives partial bits or partial digits of the logical UE identifier included in the paging message, it matches the received partial bits or partial digits of the logical UE identifier with the corresponding most significant bits (MSB) of its own stored logical UE identifier to determine whether it belongs to the paged group of UEs (or to determine whether the paged group of UEs includes this UE). In some embodiments, when the RAN and / or UE receives partial bits or partial digits of the logical UE identifier included in the paging message, the paging message also contains the paging group identifier length or the number of valid bits (or digits) of the logical UE identifier for paging, to indicate how many most significant bits (or digits) of the logical UE identifier should be matched to determine whether the UE is paged (including UE-specific paging or group paging).
[0065] As a non-limiting example, with MMEC=1001, user code=234567, and device code=80000 to 89999, when paging all AIoT UEs of the user with user code=234567, the paging message may include a paging ID (or part or part of the logical AIoT UE identifier), for example, 1001234567; when paging the first 100 UEs of the user with user code=234567 (e.g., the UEs with the smallest device codes (80000-80099)), the paging message may include a paging ID (or part or part of the logical AIoT UE identifier), such as 1001234567800. The paging message can be a paging from the CN to the RAN, or a paging from the RAN to the UE.
[0066] In some implementations, when paging a group of AIoT UEs, a logical AIoT UE identifier and a mask code can be included in the paging message to identify the group of AIoT UEs. The mask code indicates which bits or numbers should be ignored during the bit / digit matching process to determine whether an AIoT UE is being paged (including UE-specific paging or group paging). When determining whether a UE is being paged, only the bits or numbers in the logical AIoT UE identifier that are not masked (i.e., not ignored) are compared with the corresponding bits or numbers in the logical AIoT UE identifier. When they match, the AIoT UE determines that it belongs to the paged AIoT UE group and / or that the AIoT UE is being paged.
[0067] As a non-limiting example, when the paging UE ID is 100123456780001 and the mask code is 10012345678**** (indicating that the last 4 bits are masked) is included in the paging message, the AIoT UE can only match 10012345678 (i.e., masking the last 4 bits of the paging UE ID) with the highest 11 bits of its ID to determine whether it belongs to the paging AIoT UE group and / or whether the AIoT UE is being paged. In this example, the paging group can include 10,000 UEs.
[0068] In some implementations, an AIoT UE can be assigned a logical UE identifier and one or more UE paging group identifiers.
[0069] In some implementations, the total number of UEs in a UE paging group can be included in the paging message from the CN to the RAN (e.g., nodeB), so that the RAN can decide to paging the group of UEs based on factors such as network load. In some implementations, when an AIoT UE receives a paging message (including group paging), it can trigger random access (e.g., 16-bit (or more) random numbers or pseudo-random numbers (RN16) or more) or UL information transmission.
[0070] In some implementations, where a paging group contains a large number of UEs, the network may wish to divide them into several paging subgroups for paging to avoid subsequent signaling congestion caused by paging all UEs as a single large group.
[0071] In some implementations, paging subgroups can be implemented using any of the following methods.
[0072] One approach may be to divide a paging group into multiple paging subgroups using the paging group identifier length or the number of valid bits (or digits) of the logical UE identifier. When the paging group identifier length or the number of valid bits of the logical UE identifier increases by 1, the paging group may be divided into two subgroups; and / or for decimal logical UE identifiers, when the paging group identifier length or the number of valid bits of the logical UE identifier increases by 1, the paging group may be divided into 10 subgroups.
[0073] As a non-limiting example, with MMEC=1001, user code=234567, and device code=80000 to 89999, when the core network decides to page the first 100 UEs (e.g., those with the smallest device code) of the user with user code=234567, it includes paging ID 1001234567800 in the paging message from CN to RAN. When the RAN decides to divide the paging into 10 subgroups for paging UEs, it can include paging IDs 10012345678000, 10012345678001, ..., 10012345678009 in the paging message from RAN to UE for subgroup paging. Each subgroup can include 10 AIoT UEs.
[0074] Alternatively, the paging message can include the number of paging subgroups and the paging subgroup identifier for subgroup purposes. When the UE determines that it is being group-paging, it further determines whether it is included in the paging subgroups contained in the paging message as follows: When the paging message includes the number of paging subgroups and the paging subgroup identifier: the UE determines that it belongs to that paging subgroup when the logical UE identifier MOD_paging_subgroup_number = paging_subgroup_ID, where "MOD" is the remainder of the division operation. When the paging message includes the number of paging subgroups and the paging subgroup identifier, the UE determines that it is being paged only if it belongs to both the paging group and the paging subgroup.
[0075] Alternatively, the number of paging subgroups can be set to the AIoT UE via common signaling (e.g., System Information Block (SIB)). Different paging frequency resources and / or paging time domain resources correspond to different paging subgroup identifiers. The UE can monitor its paging subgroups on its frequency paging resources and / or time domain paging resources. For example, the UE can monitor paging on a paging frequency, where the paging frequency resource index = logical UE identifier MOD number of paging subgroups.
[0076] In some implementations, the network may need to inventory mobile UEs (e.g., triggering newly accessed UEs in the cell to report their status). Paging messages may include a cell identifier and / or a paging reason (e.g., mobile UE inventory, mobile UE status reporting, newly accessed UE status reporting in the cell). When a paging message is received, newly accessed UEs in the cell (e.g., determined by a cell identifier that differs from the cell identifier in the UE's most recent status report) should report their status.
[0077] In some implementations, the network may need to count inactive UEs (e.g., triggering uncounted UEs to report their status). Paging messages may include the duration of the inactivity period and / or a paging reason (e.g., inactive UE count, inactive UE status reporting, uncounted UE status reporting, etc.). When a paging message is received, UEs that have not yet been counted (e.g., determined by not having reported their status) or UEs that were not counted during the most recent inactivity period should report their status or count information.
[0078] In some embodiments, the logical UE identifier in the paging message may also be replaced by the physical device ID, such as the Electronic Product Code (EPC), Permanent Equipment Identifier (PEI), IoT device identifier, or a portion of the bits or numbers of the physical device ID.
[0079] Example Set II This disclosure describes various embodiments for performing MT procedures on an AIoT UE, particularly embodiments related to the paging resource configuration and / or selection of the AIoT UE.
[0080] In some implementations, AIoT UEs may typically operate only within a limited bandwidth (e.g., 200 kHz), and there may be a large number of AIoT UEs in the network. For a large number of AIoT UEs operating simultaneously, multiple carrier frequencies can be used in the AIoT network to achieve high capacity. The AIoT UE needs to determine the paging carrier frequency. In some implementations, frequency scanning (e.g., scanning all RF channels to find the used frequencies and / or cells) may not be supported when the AIoT UE may only support backscatter transmission (e.g., no active RF components for transmission). In some implementations, the AIoT UE can use one of the following methods to determine the paging carrier frequency.
[0081] In one approach, when a UE or TAG is generated, activated, or registered to the network (e.g., written and stored in the UE or USIM), an initial paging carrier frequency is assigned by the operator, and the UE defaults to camp on the initially assigned carrier frequency and monitors for paging. In some implementations, the operator may be a network or UE administrator; or the operator may be a remote application.
[0082] Alternatively, the paging carrier frequency can be updated via UE-specific signaling, such as AS signaling (e.g., MAC CE or RRC messages) or NAS signaling. After the update, the UE monitors for paging on the updated carrier frequency.
[0083] Alternatively, the RAN can broadcast public signaling (e.g., SIB) that includes paging carrier frequency information. The paging carrier frequency information can include one or more paging carrier frequencies. The UE monitors paging on the paging frequency, where the paging frequency index equals the logical UE identifier (MOD) multiplied by the number of paging subgroups.
[0084] Example Set III This disclosure describes various embodiments for performing MT procedures on an AIoT UE, particularly embodiments related to paging information of the AIoT UE.
[0085] In some implementations, for at least one AIoT UE, paging can have different purposes, and paging information can include paging purpose / reason involving at least one of the following: triggering inventory (e.g., reporting the status of the UE); sending downlink information to the UE (e.g., writing or updating certain parameters or information to the UE); triggering UE positioning; commanding the UE to do something (e.g., wiping an unused UE to reclaim configured resources); and / or triggering access (e.g., triggering interactive communication between the UE and the network).
[0086] In some implementations, since different paging purposes may lead to different UE behaviors and different subsequent procedures, when the network sends a paging message to at least one AIoT UE, the paging message may include a paging reason to indicate the paging purpose. The paging reason may include at least one of the purposes / reasons mentioned above, such as inventory, location, access, erasure, DO-DTT, DT, etc.
[0087] In some implementations, when paging is used to send downlink information to the UE (e.g., to write or update certain parameters or information to the UE), the paging message may also include NAS data or NAS PDU for the downlink information.
[0088] Example Set IV This disclosure describes various embodiments for performing MT procedures on an AIoT UE, particularly embodiments related to the contention resolution process of an AIoT UE.
[0089] In some implementations, for MT procedures (e.g., paging procedures, paging-triggered procedures, or paging-triggered procedures), when the paging message includes a UE identifier, the UE identifier can be determined using a contention-resolved ID (including partial UE identifier bits or partial UE identifier digits) in the first uplink transmission and / or subsequent downlink transmissions. The partial UE identifier bits or partial UE identifier digits can be the least significant bit or least significant digit of the UE identifier.
[0090] In some implementations, when the RAN (e.g., NodeB) sends a paging message including the complete UE identifier, a first part of the UE identifier bits (e.g., the most significant bit or the leftmost bit) or a first part of the UE identifier bits (e.g., the most significant bit or the leftmost digit), the NodeB can receive a first uplink transmission including a second part of the UE identifier bits (e.g., the least significant bit or the rightmost bit) or a second part of the UE identifier bits (e.g., the least significant bit or the rightmost digit); and the NodeB can determine that the UE has been identified or acknowledged by the UE, and can send subsequent downlink transmissions to the UE, including a third part of the UE identifier bits or a third part of the UE identifier bits, wherein the third part of the UE identifier bits or a third part of the UE identifier bits is the same as the second part of the UE identifier bits or a second part of the UE identifier bits, or the tail bit of the second part of the UE identifier bits, or a second part of the UE identifier bits.
[0091] In some implementations, when the UE sends a first uplink transmission including a second part of the UE identifier bits or a second part of the UE identifier digits, and receives a subsequent downlink transmission including a third part of the UE identifier bits or a third part of the UE identifier digits, the UE can determine that the UE has been identified or acknowledged by the NodeB, and can perform subsequent UE-specific transmissions and / or receptions, wherein the third part of the UE identifier bits or the third part of the UE identifier digits is the same as the second part of the UE identifier bits or the second part of the UE identifier digits, or is the tail bit of the second part of the UE identifier bits or the second part of the UE identifier digits.
