Description

Technical Field

[0001] The following content relates generally to wireless communication, and more specifically to technologies for paging Ambient Internet of Things (AIoT) devices in wireless communication systems. Background Technology

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-A Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each supporting wireless communication for communication devices, which may be referred to as User Equipment (UE). Summary of the Invention

[0003] The described technology relates to improved methods, systems, devices, and apparatuses for supporting techniques for paging wireless devices (e.g., Ambient Internet of Things (AIoT) devices) via reader devices in wireless communication systems. For example, the described technology enables one or more network devices in a wireless communication system to assist in tracking, locating, waking up, or communicating with AIoT and other wireless devices in an ambient computing environment. Such an ambient computing environment can utilize wireless devices (such as AIoT devices) to acquire information from their surroundings and provide intelligent services to users. Wireless devices can interact with one or more other devices in the ambient computing environment to provide services such as location tracking services, communication services, or identification services. For example, a wireless device can interact with a network device (such as a reader device) that can detect or read one of the wireless devices. The reader device can transmit a signal to the detected wireless device, triggering the wireless device to wake up and transmit contextual information (such as location, positioning, or other data) about the wireless device to the reader device, which may be relevant to the service to be provided. The reader device can then communicate the contextual information to one or more other network devices to facilitate the provision of services.

[0027] Various aspects of this disclosure relate to techniques for paging wireless devices (e.g., Ambient Internet of Things (AIoT) devices) via reader devices in wireless communication systems. For example, the described techniques provide means for waking up one or more wireless devices (such as AIoT devices) in an ambient computing environment to trigger wireless device wake-up. For instance, the ambient computing environment may include one or more wireless devices (e.g., AIoT devices) that interact with one or more other devices (such as one or more reader devices capable of reading wireless devices) to facilitate the provisioning of services (such as location tracking services, communication services, or identification services). The reader device may then communicate with one or more network devices (such as base stations) to further facilitate service provisioning. In some cases, the wireless device may be in a sleep state and may need to be woken up to provide services.

[0028] The aspects of this disclosure are first described in the context of a wireless communication system. These aspects are further illustrated by apparatus diagrams, system diagrams, and flowcharts relating to the technology used for paging AIoT devices in a wireless communication system, and are described with reference to these diagrams.

[0029] Figure 1An example of a wireless communication system 100 supporting techniques for paging AIoT devices in a wireless communication system, according to one or more aspects of this disclosure, is illustrated. The wireless communication system 100 may include one or more devices, such as one or more network devices (e.g., network entity 105), one or more user equipment (UE) 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-APro network, a New Radio (NR) network, or a network operating under other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein. As described herein, the term "paging" may refer to paging or enhanced paging in LTE, NR, or 6G systems, dedicated paging designed in a wireless system (e.g., an AIoT system), or a similar paging method using other terms (e.g., query) for similar purposes.

[0030] Network entity 105 may be distributed across a geographical area to form wireless communication system 100, and may include devices employing different forms or having different capabilities. In various examples, network entity 105 may be referred to as a network element, mobility element, radio access network (RAN) node, or network equipment, etc. In some examples, network entity 105 and UE 115 may wirelessly communicate via communication link 125 (e.g., a radio frequency (RF) access link). For example, network entity 105 may support coverage area 110 (e.g., a geographical coverage area) within which UE 115 and network entity 105 may establish communication link 125. Coverage area 110 may be an example of a geographical area within which network entity 105 and UE 115 may support the transmission of signals according to one or more radio access technologies (RATs).

[0031] UE 115 can be distributed throughout the coverage area 110 of wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. UE 115 can be devices in different forms or with different capabilities. Figure 1 Examples of UE 115 are illustrated herein. The UE 115 described herein may be able to support communication with various types of devices in the wireless communication system 100 (e.g., other wireless communication devices, including UE 115 or network entity 105), such as... Figure 1 As shown.

[0032] As described herein, a node in the wireless communication system 100 (which may be referred to as a network node or wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, apparatus, device, computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be UE 115. As another example, a node may be network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be UE 115. In another aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different from these examples. Similarly, references to UE 115, network entity 105, device, equipment, computing system, etc., may include disclosures of UE 115, network entity 105, device, equipment, computing system, etc., as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that a first node is configured to receive information from a second node.

[0033] In some examples, network entity 105 may communicate with core network 130, communicate with each other, or both. For example, network entity 105 may communicate with core network 130 via backhaul communication link 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, network entities 105 may communicate with each other directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130) via backhaul communication link 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, network entities 105 may communicate with each other via midhaul communication link 162 (e.g., according to midhaul interface protocol) or fronthaul communication link 168 (e.g., according to fronthaul interface protocol) or any combination thereof. The backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be one or more wired links (e.g., electrical links, fiber optic links) or one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof, or may include one or more wired links (e.g., electrical links, fiber optic links) or one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 may communicate with the core network 130 via communication link 155.

[0034] One or more network entities or network equipment described herein as network entity 105 or network equipment may include or be referred to as base station 140 (e.g., transceiver base station, radio base station, NR base station, access point, radio transceiver, node B, eNodeB (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), 5G NB, next-generation eNB (ng-eNB), home node B, home evolution node B, or other suitable terms). In some examples, network entity 105 (e.g., base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture that may be configured to utilize a protocol stack physically or logically integrated within a single network entity (e.g., network entity 105 or a single RAN node, such as base station 140).

[0035] In some examples, network entity 105 may be implemented in a decomposed architecture (e.g., a decomposed base station architecture, a decomposed RAN architecture) that can be configured to utilize protocol stacks physically or logically distributed across multiple network entities (e.g., network entity 105) such as an Integrated Access Backhaul (IAB) network, an Open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a Virtualized RAN (vRAN) (e.g., a Cloud RAN (C-RAN)). For example, network entity 105 may include one or more of the following: a Central Unit (CU) such as CU 160, a Distributed Unit (DU) such as DU 165, a Radio Unit (RU) such as RU 170, a RAN Intelligent Controller (RIC) such as RIC 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a Service Management and Orchestration (SMO) system such as SMO system 180, or any combination thereof. RU 170 may also be referred to as a radio headend, intelligent radio headend, remote radio headend (RRH), remote radio unit (RRU), or transmit / receive point (TRP). One or more components of network entity 105 in a decomposed RAN architecture may be co-located, or one or more components of network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities in network entity 105 of a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0036] The functional splitting among CU 160, DU 165, and RU 170 is flexible and can support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a protocol stack functional splitting can be used between CU 160 and DU 165, allowing CU 160 to support one or more layers of the protocol stack, and DU 165 to support one or more different layers of the protocol stack. In some examples, CU 160 can host upper protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionality and signaling (e.g., Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). CU 160 (e.g., one or more CUs) may connect to DU 165 (e.g., one or more DUs) or RU 170 (e.g., one or more RUs) or a combination thereof, and DU 165, RU 170, or both may host lower protocol layers, such as Layer 1 (L1) (e.g., Physical (PHY) layer) or L2 (e.g., Radio Link Control (RLC) layer, Medium Access Control (MAC) layer) functionality and signaling, and may each be at least partially controlled by CU 160. Additionally or alternatively, a protocol stack functional split may be employed between DU 165 and RU 170, such that DU 165 may support one or more layers of the protocol stack, and RU 170 may support one or more different layers of the protocol stack. DU 165 may (e.g., via one or more different RUs, such as RU 170) support one or more different cells. In some cases, functional decomposition between CU 160 and DU 165, or between DU 165 and RU 170, can be performed within the protocol layer (e.g., some functions of the protocol layer can be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer can be performed by a different one of CU 160, DU 165, or RU 170). CU 160 can be further functionally decomposed into CU control plane (CU-CP) functions and CU user plane (CU-UP) functions. CU 160 can be connected to DU 165 via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to RU 170 via fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, the midhaul communication link 162 or the fronthaul communication link 168 may be implemented based on the interfaces (e.g., channels) between the layers of the protocol stack, which are supported by corresponding network entities (e.g., one or more network entities in network entity 105) that communicate via such communication links.

[0037] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access can support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities of network entity 105 (e.g., network entity 105 or IAB node 104) may be partially controlled by each other. IAB node 104 may be referred to as a donor entity or IAB donor. DU 165 or RU 170 may be partially controlled by CU 160 associated with network entity 105 or base station 140 (such as a donor network entity or donor base station). One or more donor entities (e.g., IAB donors) may communicate with one or more additional devices (e.g., IAB node 104) via supported access and backhaul links (e.g., backhaul communication link 120). IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DU 165) of a coupled IAB donor. The IAB-MT may be equipped with a separate set of antennas for relaying communication with UE 115, or may share the same antennas (e.g., those of RU 170) for access to IAB node 104 via DU 165 of IAB node 104. (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, IAB node 104 may include one or more DUs (e.g., DU 165) that support communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., IAB node 104, or components of IAB node 104) may be configured to operate according to the techniques described herein.

[0038] When the techniques described herein are applied in the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture can be configured to support the tests described herein. For example, some operations described as being performed by UE 115 or network entity 105 (e.g., base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., components such as IAB node, DU 165, CU 160, RU 170, RIC 175, SMO system 180).

[0039] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other suitable term, wherein “device” may also be referred to as a unit, station, terminal, or client, etc. UE 115 may also include or be referred to as personal electronic devices, such as cellular phones, personal digital assistants (PDAs), multimedia / entertainment devices (e.g., radios, MP3 players, or video devices), cameras, gaming devices, navigation / positioning devices (e.g., GNSS (Global Navigation Satellite System) devices based on, for example, GPS (Global Positioning System), BeiDou, GLONASS, or Galileo, or terrestrial devices), tablet computers, laptop computers, netbooks, smartbooks, personal computers, smart devices, wearable devices (e.g., smartwatches, smart clothing, smart glasses, virtual reality goggles, smart wristbands, smart jewelry (e.g., smart rings, smart bracelets)), drones, robots / robotic devices, vehicles, vehicle equipment, meters (e.g., parking timers, electricity meters, gas meters, water meters), monitors, air pumps, electrical appliances (e.g., kitchen appliances, washing machines, dryers), location tags, medical / healthcare devices, implants, sensors / actuators, displays, or any other suitable device configured to communicate via wireless or wired media. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, IoT device, Internet of Things (IoE) device, or machine-type communication (MTC) device, etc., which may be implemented in various items such as appliances, vehicles, or meters, etc.

[0040] The UE 115 described herein can communicate with various types of devices, such as other UEs 115 that sometimes operate as repeaters, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown.

[0041] UE 115 and network entity 105 can wirelessly communicate with each other via communication link 125 (e.g., one or more access links) using resources associated with one or more carriers. The term "carrier" can refer to a set of RF spectrum resources having a defined PHY layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the RF spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR). Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operation for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured using multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers. Communication between network entity 105 and other devices can refer to communication between these devices and any part of network entity 105 (e.g., entity, sub-entity). For example, the terms “send,” “receive,” or “communicate” when referring to network entity 105 can refer to any part of the RAN’s network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities, such as one or more network entities in network entity 105).

[0042] The signal waveform transmitted via a carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the decoding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high modulation scheme order correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0043] The time interval for network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, which can be, for example, the sampling period. seconds, in response It can represent the supported subcarrier spacing, and The supported Discrete Fourier Transform (DFT) size can be represented. Time intervals for communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0044] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems, such as wireless communication system 100, time slots may be further divided into multiple micro-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., The duration of a symbol period is associated with a (number) sampling period. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0045] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0046] Depending on the technology, carriers can be used to multiplex physical channels for communication. One or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used, for example, to multiplex physical control channels and physical data channels for signaling via a downlink carrier. The control region (e.g., control resource set (CORESET)) of the physical control channel can be defined by a set of symbol periods and can extend across the system bandwidth of the carrier or a subset of that bandwidth. One or more control regions (e.g., CORESET) can be configured for a set of UEs 115. For example, one or more UEs in UE 115 can monitor or search for control regions to obtain control information based on one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a concatenated manner. The aggregation level of control channel candidates can refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space set may include a common search space set configured to transmit control information to UE 115 (e.g., one or more UEs), or it may include a UE-specific search space set configured to transmit control information to UE 115 (e.g., a particular UE).

[0047] In some examples, network entity 105 (e.g., base station 140, RU 170) may be mobile, and thus provide communication coverage to mobile coverage areas (such as coverage area 110). In some examples, coverage areas 110 associated with different technologies (e.g., different coverage areas) may overlap, but coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., network entity 105). In some other examples, overlapping coverage areas (such as coverage area 110) associated with different technologies may be supported by different network entities (e.g., network entity 105). The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 use the same or different RATs to support communication to coverage areas 110 (e.g., different coverage areas).

[0048] Some UEs 115 (such as MTC or IoT devices) can be relatively low-cost or low-complexity devices and can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with network entities 105 (e.g., base station 140) without human intervention. In some examples, M2M communication or MTC may include communication from devices with integrated sensors or meters to measure or acquire information and relay such information to a central server or application that uses the information or presents it to people interacting with the application. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based service charging. In one respect, the technologies disclosed herein are applicable to MTC or IoT UEs. MTC or IoT UE can include MTC / enhanced MTC (eMTC, also known as CAT-M, Cat M1) UE, NB-IoT (also known as CAT NB1) UE, and other types of UE. eMTC and NB-IoT can refer to future technologies that can evolve from or are based on these technologies. For example, eMTC can include FeMTC (further eMTC), eFeMTC (further enhanced eMTC), and mMTC (massive MTC), while NB-IoT can include eNB-IoT (enhanced NB-IoT) and FeNB-IoT (further enhanced NB-IoT).

[0049] Some UE 115s can be configured to operate in a power-saving mode, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but does not transmit and receive concurrently). In some examples, half-duplex communication can be performed at a reduced peak rate. Other power-saving techniques for UE 115 may include entering a power-saving deep sleep mode when not engaged in active communication, operating with limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UE 115s can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a carrier's guard band, or outside a carrier.

[0050] Wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communication may include private or group communication and may be supported by one or more services, such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritizing services, and such services may be used for public safety or general business applications. The terms “ultra-reliable,” “low-latency,” and “ultra-reliable low-latency” are used interchangeably herein.

[0051] In some examples, UE 115 may be configured to support direct communication with other UEs (e.g., one or more UEs in UE 115) via a device-to-device (D2D) communication link (such as D2D communication link 135) (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group performing D2D communication may be within the coverage area 110 of network entity 105 (e.g., base station 140, RU 170), which may support aspects of such D2D communication configured (e.g., scheduled by network entity 105). In some examples, one or more UEs 115 in this group may be outside the coverage area 110 of network entity 105, or may otherwise be unable or not configured to receive transmissions from network entity 105. In some examples, a group of UEs 115 communicating via D2D communication can support a one-to-many (1:M) system, in which each UE 115 transmits to one or more UEs in the group. In some examples, network entity 105 can facilitate the scheduling of resources used for D2D communication. In some other examples, D2D communication can be performed between UEs 115 without involving network entity 105.

[0052] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function (UPF)) for routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by network entity 105 (e.g., base station 140) associated with core network 130. User IP packets can be transferred through user plane entities, which provide IP address allocation and other functions. User plane entities can connect to one or more network operator IP services 150. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0053] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the area from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) band or decimeter band because the wavelength range is approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves are sufficient to penetrate structures so that macrocells can provide service to UE 115 located indoors. Compared to communication using smaller frequencies and longer wavelengths in the lower frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, communication using UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers).

[0054] Wireless communication system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may employ licensed assisted access (LAA), LTE-Unlicensed (LTE-U) RAT, or NR technology using unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating with unlicensed RF spectrum, devices such as network entity 105 and UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation using unlicensed frequency bands may be based on carrier aggregation configurations combined with component carriers operating with licensed frequency bands (e.g., LAA). Operation using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0055] Network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some examples, the antennas or antenna arrays associated with network entity 105 may be located at different geographical locations. Network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that network entity 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may include one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.

[0056] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., network entity 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating along a specific orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each of these antenna elements may be defined by a beamforming weight set associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device or relative to some other orientation).

[0057] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or PDCP layer can be IP-based. The RLC layer performs packet segmentation and reassembly for transmission via logical channels. The MAC layer performs priority processing and multiplexing of logical channels to transport channels. The MAC layer can also implement error detection, error correction, or both to support retransmission and improve link efficiency. In the control plane, the RRC layer can provide the establishment, configuration, and maintenance of RRC connections between the UE 115 and network entity 105 or core network 130 supporting user plane data radio bearers. The PHY layer maps transport channels to physical channels.

[0058] Some wireless communication systems may include, operate within, or be integrated with an environmental computing environment. Such environmental computing environments can utilize connected wireless devices (such as AIoT devices) to acquire information from their surroundings and provide intelligent services to users. In some cases, the wireless devices included in an environmental computing environment may include devices with energy harvesting (EH) capabilities (e.g., radio frequency identification (RFID) tags), devices without EH capabilities, battery-powered devices, or other wireless devices. Wireless devices may interact with one or more other devices in the environmental computing environment to provide services, such as location tracking services. For example, wireless devices may interact with network devices (such as reader devices) that can detect or read wireless devices. In some cases, the reader device may be UE 115 or network entity 105 (such as base station 140). The reader device may communicate with one or more other network devices (such as one or more other network entities 105) to provide services. In some cases, network entity 105 may command the reader device to wake up (e.g., page) one or more wireless devices to trigger a transition from an idle or inactive state to an awake state in order to provide services.

[0059] Figure 2 An example of a portion of a wireless communication system 200, which supports techniques for paging AIoT devices in a wireless communication system according to one or more aspects of this disclosure, is shown.

[0060] The wireless communication system 200 may include network entity 130-a, network entity 105-a, one or more reader devices 250 (e.g., UE reader device 250-a and base station reader device 250-b), and one or more wireless devices 215 (e.g., wireless devices 215-a, 215-b, 215-c, and 215-d). Network entity 130-a may be as shown in the reference. Figure 1 The example described is the core network 130 or network entity 105. Network entity 105-a and base station reader device 250-b can be as shown in the reference. Figure 1 The network entity 105 or base station 140 described is an example. The UE reader device 250-a can be as shown in the reference. Figure 1 Example of UE115 described. Network entity 130-a, network entity 105-a, UE reader device 250-a, base station reader device 250-b, and one or more wireless devices 215 can communicate using communication links (such as communication links 125-a, 125-b, 125-c, 125-d, 125-e, 125-f, 125-g, and 125-h).

[0061] In some cases, network entity 130-a may provide services such as location tracking services associated with one or more wireless devices 215. In some cases, it may be necessary to locate one or more of the wireless devices 215. For example, wireless device 215 may be a low-power, low-complexity AIoT device, such as a tag (e.g., a radio frequency ID (RFID) tag) attached to a suitcase, pet, a set of keys, or other item, and network entity 130-a may facilitate the provision of location tracking services for tracking the location of wireless device 215.

[0062] Compared to other user equipment (such as UE 115), wireless device 215 can have minimal circuitry and processing power, and can be smaller and cheaper than previous generations of IoT devices (such as Narrowband (NB)-IoT, Long Term Machine Type Evolution (LTE-M), and Enhanced Reduced Capability (eRedCap) IoT devices). These devices can also have minimal power storage capacity, and in some cases, the primary power source for such devices can be radio waves transmitted from signals (e.g., continuous wave or NR signals) from another device (such as a reader device, e.g., reader device 250). In some cases, wireless device 215 can employ technology similar to passive UHF RFID. Therefore, in some cases, due to its low power, low complexity, and limited processing capabilities, wireless device 215 may not support certain standard features or functionalities compared to other user equipment or IoT devices. Additionally, different wireless devices 215 can have different capabilities or support different functions. For example, in some cases, wireless device 215 may be a first type of wireless device 215 (e.g., device type 1) or a second type of wireless device 215 (e.g., device type 2).

[0063] The first type of wireless device 215 (e.g., device type 1) may be a wireless device with the ability to store a limited amount of energy but may not be able to generate signals independently. Instead, the first type of wireless device 215 may be an EH-capable device that uses backscattering to transmit one or more signals based on a received signal (e.g., radio waves). For example, the first type of wireless device 215 may collect energy received from radio waves transmitted by a signal transmitted by a reader device 250. The first type of wireless device 215 may use the collected energy to perform backscattering to send one or more signals back to the reader device 250 or another device that transmitted the initial signal, such as by receiving the signal through reflection. These wireless devices 215 may have a peak power consumption of approximately 1 µW.

[0064] The second type of wireless device 215 (e.g., device type 2) may have the ability to store more energy than the first type of wireless device 215. This type of device can be further classified into various subtypes. For example, a first subtype of the second type of wireless device 215 may include energy storage, may have an initial sampling frequency offset (SFO) of up to 10X (e.g., 10 times) parts per million (ppm), and may communicate based on backscattering on an external carrier. This type of wireless device may have neither downlink amplification nor uplink amplification capabilities, and the device's uplink transmission may be backscattered on an externally provided carrier. A second subtype of the second type of wireless device 215 may include energy storage, may also have an initial SFO of up to 10X ppm, and may communicate based on an internally generated carrier. This type of wireless device may additionally have downlink amplification capabilities or uplink amplification capabilities. Therefore, the device's uplink transmission may be generated independently by the device or may be backscattered on an externally provided carrier. These wireless devices 215 may have peak power consumption of less than a few hundred µW.

[0065] In some cases, network entity 130-a may locate or track wireless device 215 with the assistance of one or more reader devices 250. Reader device 250 may refer to devices associated with network entity 130-a that can be used to detect or read one or more wireless devices in wireless device 215. For example, reader device 250 may be UE reader device 250-a or base station reader device 250-b. Network entity 130-a may communicate with UE reader device 250-a via network entity 105-a, and UE reader device 250-a may be connected through network entity 105-a. For example, network entity 130-a may transmit a control signal (in some cases, the control signal may be a paging signal or a paging-like signal) to network entity 105-a, which instructs network entity 105-a to command one or more UE reader devices 250-a to track or locate one or more wireless devices in wireless device 215. Additionally or alternatively, network entity 130-a may communicate directly with base station reader device 250-b and may directly transmit control signals (in some cases, the control signals may be paging signals or similar signals) to base station reader device 250-b, which command base station reader device 250-b to track one or more wireless devices in wireless device 215.

[0066] In some cases, network entity 130-a may wish to track or locate a specific wireless device 215, for example, to locate a wireless device 215-a attached to a lost suitcase. In other cases, network entity 130-a may wish to track or locate multiple wireless devices 215, for example, to receive location or other contextual information about multiple wireless devices 215. Locating multiple wireless devices 215 can allow those wireless devices to be inventoried by the reader device 250 that locates them. This can facilitate tracking and locating a specific wireless device 215 at a later time. For example, when reader device 250 locates wireless device 215, reader device 250 can collect information associated with the located wireless device 215 (such as identification and location information associated with reader device 250 and wireless device 215) and send that information to network entity 130-a or an AIoT server. Network entity 130-a or the AIoT server can store an inventory record from each reader device 250. In this manner, when a specific wireless device 215 needs to be located, network entity 130-a can query inventory records to identify the last known reader device 250 that located (or inventoried) the specific wireless device 215. Network entity 130-a can then target one or more of the known reader devices 250 that located the specific wireless device 215 to command them to locate the specific wireless device 215 again. In some cases, the last known reader device may also be referred to as known reader device 250 or reader device 250 known to network entity 130-a. Known reader device 250 (or reader device 250 known to network entity 130-a) may include the last known reader device 250 that has been inventoried (e.g., located, detected, read) the specific wireless device 215, and in some cases, may additionally include other reader devices 250 that have previously inventoried the specific wireless device 215.

[0067] In some instances, network entity 130-a may additionally or alternatively target other reader devices 250 to locate a specific wireless device 215. For example, network entity 130-a may target neighboring reader devices 250 of a known reader device 250. When the known reader device is a base station reader device 250-b, the neighboring reader device 250 may be a UE reader device 250-a controlled by or registered at the known base station reader device 250-b, or it may be another base station reader device 250-b located near the known base station reader device 250-b. When the known reader device is a UE reader device 250-a, the neighboring reader device 250 may be another UE reader device 250-a located in the same cell as the known UE reader device 250-a or registered at the same base station. In other instances, network entity 130-a may target a reader device 250 that is in the same device paging area or tracking area as a known reader device 250 that previously located a specific wireless device 215. Network entity 130-a may manage to limit the device paging area or may reuse the tracking area. In other instances, network entity 130-a may target a UE reader device 250-a associated with one or more base stations of a known UE reader device 250-a. For example, an AIoT paging may be transmitted to one or more such base stations, which may then send the AIoT paging to one or more UE reader devices 250-a.

[0068] When identifying a specific reader device 250 for use in tracking or locating one or more wireless devices among wireless devices 215, network entity 130-a may transmit a signal to reader device 250 instructing it to page one or more wireless devices 215 to trigger wake-up and the transmission of their identification information and other contextual information (such as location information). In some cases, such as when the reader device is a UE reader device 250-a, network entity 130-a may transmit signals to reader device 250 via an intermediate network entity (such as network entity 105-a associated with UE reader device 250-a). For example, network entity 130-a may send a signal to network entity 105-a instructing the managed UE reader device 250-a to page one or more wireless devices to trigger wake-up.

[0069] The signal transmitted from network entity 130-a or network entity 105-a to reader device 250, in which reader device 250 pages one or more wireless devices 215 to trigger wake-up, can be a control signal, such as a first control signal 210 (e.g., a first control signal 210-a from network entity 105-a to UE reader device 250-a or a first control signal 210-b from network entity 130-a to base station reader device 250-b). In some embodiments, the signaling layer of the first control signal 210 can be application layer signaling when the signaling is triggered by an AIoT server, or a NAS signal when the signaling is triggered by network entity 130-a (e.g., by an AIoT controller at the core network). In some embodiments, the control signaling can be RRC signaling, such as when sent to UE reader device 250-a with an RRC connection.

[0070] Upon receiving the first control signal 210, the reader device 250 may send a second control signal 220 (e.g., a second control signal 220-a from UE reader device 250-a or a second control signal 220-b from base station reader device 250-b) to one or more wireless devices such as those indicated by the first control signal 210, such as a reader-to-device (R2D) paging signal (also known as a query command).

[0071] One or more wireless devices 215 may receive the second control signal 220-b and may send an acknowledgment message or feedback 230 (e.g., feedback 230-a sent to UE reader device 250-a or feedback 230-b sent to base station reader device 250-b) back to reader device 250. In some cases, feedback 230 may include identification information associated with wireless device 215, contextual information associated with wireless device 215 (such as location information), or a combination thereof.

[0072] In response to receiving feedback 230 from wireless device 215, reader device 250 may send a response message 240 (e.g., response message 240-a from UE reader device 250-a or response message 240-b from base station reader device 250-b) to network entity 105-a or network entity 130-a (response message 240-a may additionally be sent from network entity 105-a to network entity 130-a). Response message 240 may include identification or contextual information transmitted in the feedback 230 from wireless device 215, and in some cases, may additionally include contextual information (such as location information) associated with reader device 250. If feedback 230 is not received within a predetermined time period, response message 240 may include a failure message indicating that wireless device 215 cannot be located. Based on response message 240, network entity 130-a can provide an indication to an AIoT service (such as tracking or location service) of the location of a specific paged wireless device 215 or an indication that the wireless device 215 cannot be located.

[0073] Figure 3 An example of a signal flow 300 supporting a technology for paging AIoT devices in a wireless communication system, according to one or more aspects of this disclosure, is shown.

[0074] In some respects, signal flow 300 can achieve, as referenced separately Figure 1 and Figure 2 The described aspects of wireless communication system 100 or wireless communication system 200, or aspects implemented by these aspects. Signal flow 300 may exemplify the signal flow between wireless device 315, reader device 350, and network entity 305. Wireless device 315 may be as described in reference... Figure 2 An example of a wireless device in the described wireless device 215. Reader device 350 may be as shown in the reference. Figure 2 Examples of UE reader devices 250-a or base station reader devices 250-b described herein. Network entity 305 may be as shown in the reference. Figure 2 Examples of network entity 130-a (such as when reader device 350 is a base station reader device) or network entity 105-a (such as when reader device 350 is a UE reader device).

[0075] Network entity 305 can send a first control signal 310 to reader device 350. The first control signal 310 can be as shown in the reference... Figure 2An example of the described first control signal 210. The first control signal 310 can be sent from network entity 305 to reader device 350 to command reader device 350 to page one or more target wireless devices (such as one or more wireless devices 315) to trigger a wake-up at wireless device 315. For example, network entity 305 can receive instructions or requests from an AIoT service to locate one or more specific wireless devices 315 (e.g., one or more AIoT devices) or to communicate with them. Network entity 305 can identify one or more reader devices 350 as targets to assist in locating one or more wireless devices 315. For example, network entity 305 can query an AIoT server to identify which reader devices have inventoried one or more wireless devices 315, such as the last known reader device that has inventoried one or more wireless devices 315 (or other reader devices associated with such devices), such as references. Figure 2 As described. The first control signal 310 may be sent to one or more reader devices among the identified reader devices, such as reader device 350. For example, if wireless device 1 and wireless device 2 are to be located, and if the last known reader device for wireless device 1 is reader device A and reader device B, and if the last known reader device for wireless device 2 is reader device B, then network entity 305 may send the first control signal 310 with an indication of paging wireless device 1 to reader device A, and may send the first control signal 310 with an indication of paging wireless device 1 and wireless device 2 to reader device B.

[0076] The first control signal 310 may be similar to a paging signal typically sent from a network entity to a UE to trigger UE wake-up. However, according to the aspects described herein, the first control signal 310 may be enhanced (e.g., relative to a conventional paging signal) to include additional information elements. For example, conventionally, a paging signal from a network entity to a UE may include information identifying the specific UE being paged (such as a unique identifier associated with the UE). In this way, when the UE receives the paging signal, the UE can recognize that the paging signal is intended for the UE, and the UE can wake up its radio components or receiver to receive upcoming data messages (such as a request for an RRC connection). However, according to the aspects described herein, because the first control signal 310 transmitted from network entity 305 to reader device 350 is not intended to trigger wake-up or become an RRC connection at reader device 350 itself, the first control signal 310 may include additional information elements to notify reader device 350 that reader device 350 will instead page one or more radio devices 315 to trigger device wake-up. Therefore, the first control signal 310 may include information identifying one or more radio devices 315 to be paged.

[0077] The identification information included in the first control signal 310 may include an indication of an identifier (e.g., reader ID) associated with the reader device 350 to which the first control signal 310 is transmitted, and an identifier (e.g., wireless device ID, such as AIoT device ID) associated with one or more wireless devices 315 that are the target for locating and triggering wake-up. In some implementations, the identifier (e.g., wireless device ID) associated with one or more wireless devices 315 may be an Electronic Product Code (EPC), a unique ID assigned by network entity 305 or by the AIoT server, a unique ID assigned by the PHY layer (such as a Radio Network Temporary Identifier (RNTI)), a group ID associated with wireless device 315, a device type ID associated with wireless device 315 (such as device type 1 or device type 2), a corresponding L1-ID of wireless device 315, or any other identifier associated with wireless device 315. In some cases, the one or more wireless devices 315 identified in the first control signal 310 may be based on requirements from application functions (such as AIoT services) or from network entity 305 (such as criterion filters).

[0078] When reader device 350 receives the first control signal 310, it can initially check the identification information included in the first control signal 310 to obtain a reader ID associated with it, thereby confirming that the first control signal 310 is for reader device 350. If the reader ID in the first control signal 310 matches the identification information associated with reader device 350, reader device 350 can further check the identification information included in the first control signal 310 to obtain one or more wireless device IDs. If the identification information does not include a wireless device ID, reader device 350 can confirm that the first control signal 310 is intended as a paging message for reader device 350 (such as a message indicating an upcoming event for reader device 350). However, if the identification information includes one or more wireless device IDs, this can instruct reader device 350 that the first control signal 310 is instead intended as an instruction for reader device 350 to page the indicated wireless device 315.

[0079] Based on the determination that the first control signal 310 is intended as an instruction for the reader device 350 to page one or more indicated wireless devices 315, the reader device 350 may send a second control signal 320 (e.g., an R2D paging signal) to the indicated wireless devices 315. The second control signal 320 may include identification information (such as a wireless device ID) of the paged one or more wireless devices 315. In some cases, the second control signal 320 may be referred to as a unicast query command or a multicast query command.

[0080] One or more wireless devices among the wireless devices 315 to which the second control signal 320 is sent can detect or receive the second control signal 320. When a wireless device 315 detects the second control signal 320, it can be triggered to wake up and check the identification information (such as a wireless device ID) included in the second control signal 320. If the identification information associated with the wireless device 315 matches one of the wireless device IDs in the second control signal 320, the wireless device 315 can perform an inventory process. The inventory process may involve the wireless device 315 transmitting feedback 330 to the reader device 350 in response to receiving the second control signal 320, and in some cases, the inventory process may be performed based on one or more parameters included in the second control signal 320. For example, in some cases, the wireless device 315 may be an EH-capable device that can collect (or, in some cases, store) energy from the received second control signal 320 output by the reader device 350. For example, when the wireless device 315 is an EH-enabled device, upon receiving the second control signal 320, the wireless device 315 can use the energy from the received signal to send one or more backscattered signals, including feedback 330, back to the reader device 350 (or different reader devices). In other cases, the wireless device 315 may be a device without EH capability or a battery-powered device, and may send backscattered or non-backscattered signals, including feedback 330, to the reader device 350 (or to different reader devices) in response to receiving the second control signal 320.

[0081] Feedback 330 may include an indication of identification information for wireless device 315, may include an ACK message, and may additionally or alternatively include contextual information associated with wireless device 315. Contextual information may be information associated with providing an AIoT service that initially triggered or requested paging of wireless device 315, or information necessary to provide an AIoT service that initially triggered or requested paging of wireless device 315. For example, contextual information may include information collected from receivers or sensors located at wireless device 315, such as location or positioning information associated with wireless device 315, environmental information associated with the surrounding environment of wireless device 315, or other information that wireless device 315 may be able to collect from the environment computing environment. After sending feedback 330, wireless device 315 may access reader device 350 or use reader device 350 to perform its own positioning.

[0082] In response to receiving feedback 330 from one or more wireless devices 315, reader device 350 may send a response message 340 to network entity 305. The response message 340 may be in response to a first control signal 310 sent from network entity 305 to reader device 350 indicating that one or more wireless devices 315 should be paged.

[0083] If reader device 350 has located each of the indicated wireless devices 315, response message 340 may be a success message that includes a list of identification information for wireless devices 315 (e.g., a list of wireless device IDs) and relevant contextual information (such as location or positioning information) transmitted in feedback 330 from each wireless device 315. For example, response message 340 may include the wireless device ID associated with wireless device 315 and contextual information associated with wireless device 315 (such as location or positioning). In some cases, response message 340 may additionally include contextual information (such as location or positioning information) associated with reader device 350. That is, in some cases, one or more wireless devices in wireless devices 315 may not have the ability to independently collect contextual information (e.g., may not be able to independently determine their own location), or the collected contextual information may be less accurate due to the low complexity and processing power of wireless device 315. Therefore, contextual information associated with reader device 350 can be used to determine, approximate, or supplement the contextual information associated with wireless device 315. For example, the location or position of the reader device 350 can be combined with the distance of the wireless device 315 from the reader device 350 (such as by measuring the signal strength of the signal from the wireless device 315, including the feedback 330) to determine the location or position of the wireless device 315.

[0084] If the reader device 350 has found some, but not all, of the indicated wireless devices 315 (e.g., indicated in the first control signal 310), the response message 340 may be a success message indicating a list of identification information (e.g., a list of wireless device IDs) of the found wireless devices 315 and relevant context information associated with the found wireless devices 315 or context information associated with the reader device 350. In some cases, the reader device 350 may additionally and optionally send a response message 340, which may be a failure message including a list of the indicated wireless devices 315 that were not found.

[0085] If the reader device 350 has not yet found the indicated wireless device 315 (e.g., indicated in the first control signal 310), the response message 340 may be a failure message indicating no identification information for the wireless device, since the list of wireless devices 315 may be known to the network entity 305.

[0086] In some cases, reader device 350 may monitor for feedback 330 from wireless device 315 for a predetermined period of time before determining that a failure message has been sent. For example, if no feedback 330 is received within the predetermined period of time, response message 340 may include a failure message indicating that wireless device 315 could not be located. If any wireless device 315 is found, reader device 350 may provide feedback indicating that a found wireless device 315 was found within a timer. If no wireless device 315 is found and reader device 350 does not provide feedback before the timer expires, network entity 305 may determine that reader device 350 did not find any wireless device 315 due to the timer expiring.

[0087] In some cases, if wireless device 315 is not located, network entity 305 may adjust the reader devices 350 selected for locating wireless device 315, and a first control signal 310 may be transmitted to the set of these new reader devices 350. For example, initially, network entity 305 may select reader devices 350 that are known to have already been inventoried of wireless device 315. If these reader devices 350 are not used to locate wireless device 315, network entity 305 may select reader devices 350 that are adjacent to the known reader devices, and the first control signal 310 may be transmitted to those reader devices 350. If these reader devices 350 are not used to locate wireless device 315, network entity 305 may select reader devices 350 that are adjacent to the adjacent reader devices of the known reader devices (e.g., reader devices such as those in the same device paging or tracking area), and the first control signal 310 may be transmitted to those reader devices 350. If these reader devices 350 are not used to locate the wireless device 315, the network entity 305 can expand the device paging area and transmit the first control signal 310 to the reader devices 350 within the expanded paging area. If these reader devices 350 are not used to locate the wireless device 315, the network entity 305 can select UE reader devices 350 managed by a network entity associated with a known UE reader device and transmit the first control signal 310 to those reader devices 350 (or to a network entity for transmission to the UE reader device). If these reader devices 350 are not used to locate the wireless device 315, the network entity 305 can transmit the first control signal 310 to neighboring network entities of the known base station reader device 350.

[0088] Based on the received response message 340, network entity 305 can provide the requesting AIoT service with an indication of the location of wireless device 315 or an indication that one or more wireless devices 315 cannot be located. In some cases, network entity 305 can determine failure when no response is received after a duration (e.g., response timeout) or when network entity 305 receives failure feedback from some readers or up to all readers. In some cases, network entity 305 can monitor response messages 340 from reader devices 350 for a predetermined period of time before determining failure. For example, if no response message 340 is received within the predetermined period of time, network entity 305 can determine failure, for example, when one or more wireless devices 315 cannot be located. If a response message 340 is received within the predetermined period of time but does not indicate the identification information of one or more wireless devices 315, network entity 305 can determine failure for the one or more wireless devices 315 that were not indicated.

[0089] Figure 4 An example of a signal flow 400 supporting a technique for paging AIoT devices in a wireless communication system, according to one or more aspects of this disclosure, is shown. In some aspects, the signal flow 400 may implement as described in reference respectively. Figure 1 , Figure 2 and Figure 3 The described aspects of wireless communication system 100, wireless communication system 200, or signal flow 300, or implementations thereof, are described. Signal flow 400 may exemplify the signal flow between wireless device 415, reader device 450, and network entity 405. Wireless device 415 may be as described in references to... Figure 2 and Figure 3 An example of one of the wireless devices described in wireless device 215 or wireless device 315. Reader device 450 may be as shown in the reference. Figure 2 and Figure 3 Examples of UE reader device 250-a, base station reader device 250-b, or reader device 350 described herein. Network entity 405 may be as shown in the reference. Figure 2 and Figure 3 Examples of network entity 130-a (such as when reader device 450 is a base station reader device), network entity 105-a (such as when reader device 450 is a UE reader device), or network entity 305.

[0090] Network entity 405 can send a first control signal 410 to reader device 450. The first control signal 410 can be, as referred to respectively... Figure 2 and Figure 3Examples of the described first control signal 210 or first control signal 310. Specifically, the first control signal 410 may be similar to the first control signal 310, but may be further enhanced to include a paging or wake-up reason. The paging or wake-up reason may include an indication that the first control signal 410 intends to cause the reader device 450 to page the wireless device 415 included in the identification information of the first control signal 410. For example, the paging or wake-up reason may indicate "AIoT paging" or "AIoT wake-up". In some cases, the paging or wake-up reason may include an indication of the service that caused the paging (e.g., an AIoT service), or may additionally or alternatively include other information associated with the first control signal 410.

[0091] In this scenario, when reader device 450 receives the first control signal 410, it can initially check the wake-up reason to determine whether the first control signal is intended to cause it to page one or more wireless devices. If the wake-up reason indicates "AIoT paging" or "AIoT wake-up," or if the reason for providing the first control signal 410 is another indication to wake up a device different from reader device 450, reader device 450 can further check the identification information included in the first control signal 410. That is, reader device 450 can check the identification included in the first control signal 410 to obtain the reader ID associated with it, thereby confirming that the first control signal 410 is for reader device 450. If the reader ID in the first control signal 410 matches the identification information associated with reader device 450, reader device 450 can further check the identification information included in the first control signal 410 to obtain one or more wireless device IDs associated with the one or more wireless devices 415 that reader device 450 wants to page. If the wake-up reason does not indicate "AIoT paging" or "AIoT wake-up", or if the reason for providing the first control signal 410 is another indication to wake up a device different from the reader device 450, then the reader device 450 can confirm that the first control signal 410 is used to page the reader device 450, and can proceed without further checking the identification information of one or more wireless device IDs in the first control signal 410.

[0092] Then, the reader device 450 may send a second control signal 420 (e.g., an R2D paging signal) to one or more wireless devices 415 indicated in the first control signal 410. The second control signal 420 may include identification information (such as a wireless device ID) of the paged one or more wireless devices 415, and may also include the paging reason included in the first control signal 410.

[0093] One or more wireless devices in wireless device 415 can detect or receive the second control signal 420. When wireless device 415 detects the second control signal 420, wireless device 415 can be triggered to wake up and check the wake-up reason and identification information (such as wireless device ID) included in the second control signal 420. For example, if the wake-up reason indicates "AIoT paging" or "AIoT wake-up," or if providing the reason for the second control signal 420 is another indication to wake up the wireless device, then wireless device 415 can then confirm whether the identification information associated with wireless device 415 matches one of the wireless device IDs in the second control signal 420. If the identification information matches, wireless device 415 can perform an inventory process. The inventory process may involve wireless device 415 transmitting feedback 430 to reader device 450 in response to receiving the second control signal 420, and may be performed based on a specific wake-up reason included in the second control signal 420 or based on one or more other parameters included in the second control signal 420. Feedback 430 may include indications of identification information for wireless device 415, and may additionally or alternatively include contextual information associated with wireless device 415.

[0094] In response to receiving feedback 430 from one or more wireless devices 415, reader device 450 may send a response message 440 to network entity 405. The response message 440 may be in response to a first control signal 410 sent from network entity 405 to reader device 450 indicating that one or more wireless devices 415 should be paged. Figure 3 The described success or failure message, and can be categorized by about Figure 3 The method described is used to determine this.

[0095] Based on the received response message 440, network entity 405 can provide the requesting AIoT service with an indication of the location of wireless device 415 or an indication that one or more wireless devices 415 cannot be located.

[0096] Figure 5 An example of a signal flow 500 supporting a technique for paging AIoT devices in a wireless communication system, according to one or more aspects of this disclosure, is shown. In some aspects, the signal flow 500 may implement as described in reference respectively. Figure 1 , Figure 2 , Figure 3 and Figure 4 The described wireless communication system 100, wireless communication system 200, signal flow 300, or signal flow 400 are aspects of, or are implemented by, these aspects. Signal flow 500 may exemplify the signal flow between wireless device 515, reader device 550, and network entity 505. Wireless device 515 may be as described in references to, respectively. Figure 2 , Figure 3 and Figure 4 An example of one of the described wireless devices, wireless device 215, wireless device 315, or wireless device 415. Reader device 550 may be as described in the reference. Figure 2 , Figure 3 and Figure 4 Examples of UE reader device 250-a, base station reader device 250-b, reader device 350, or reader device 450 described herein. Network entity 505 may be as shown in the reference. Figure 2 , Figure 3 and Figure 4 Examples of network entity 130-a (such as when reader device 550 is a base station reader device), network entity 105-a (such as when reader device 550 is a UE reader device), network entity 305, or network entity 405.

[0097] Network entity 505 can send a first control signal 510 to reader device 550. The first control signal 510 can be, as referred to respectively... Figure 2 , Figure 3 and Figure 4 Examples of the described first control signal 210, first control signal 310, or first control signal 410. Specifically, the first control signal 510 may be similar to the first control signal 310 and the first control signal 410, except that the first control signal 510 may include a wake-up reason but may not include any wireless device ID. That is, in this example, there may not be a request to locate or track a specific wireless device, and instead, network entity 505 may instruct one or more reader devices in reader devices 550 to count the wireless devices 515 approaching reader device 550. In such cases, identification information may include the identifier of reader device 550 (e.g., reader device ID) but not any identifier of the wireless device. Alternatively, the identification information may include the identifier of reader device 550 (e.g., reader device ID) and a special device identification value (such as "0000000000" or "999999999") or a special flag. Additionally or alternatively, in such cases, the wake-up reason may include an indication that the first control signal 510 intends to cause the reader device 550 to count all wireless devices 515 in the vicinity of the reader device 550. For example, the wake-up reason may indicate "No AIoT Device ID" or "Paging without any ID", or may include other information to indicate that the first control signal 510 intends to cause the reader device 550 to count all wireless devices 515 in the vicinity of the reader device 550 (such as an indication of "AIoT Paging").

[0098] In this scenario, when reader device 550 receives the first control signal 510, reader device 550 can initially check the wake-up reason to determine whether the first control signal is intended to cause reader device 550 to page one or more specific wireless devices or to inventory all wireless devices 515 near reader device 550. If the wake-up reason indicates "No AIoT Device ID" or "Paging without any ID," or another indication that the first control signal 510 is intended to cause reader device 550 to inventory all wireless devices 515 near reader device 550 (e.g., "AIoT Paging"), then reader device 550 can further check the identification information included in the first control signal 510. That is, reader device 550 can check the identification included in the first control signal 510 to obtain the reader ID associated with reader device 550, thereby confirming that the first control signal 510 is used for reader device 550. If the reader ID in the first control signal 510 matches the identification information associated with the reader device 550, the reader device 550 can send a second control signal 520 (e.g., an R2D paging signal, also known as a query, which can be broadcast by default) to all wireless devices 515 near the reader device 550 to trigger an inventory process at those wireless devices 515. Therefore, when network entity 505 includes a paging or wake-up reason in the first control signal 510 indicating that the first control signal 510 is intended to cause the reader device 550 to page the wireless devices 515, if the identification information does not include the wireless device ID, the reader device 550 can confirm that the first control signal 510 is intended as a paging message for all wireless devices 515 near the reader device 550.

[0099] The second control signal 520 may not include identification information (such as a wireless device ID) or may include a specific device ID value. When the second control signal 520 does not include identification information, it may include a wake-up reason indicated in the first control signal 510, so that the wireless device 515 receiving the control signal 520 will know to perform the inventory process, even though there is no indication of a matching wireless device ID in the identification information of the second control signal 520. For example, if the second control signal 520 does not include a wake-up reason, when the wireless device 515 compares the identification information included in the second control signal 520 with its own identification information and does not find a matching identification information (e.g., no matching wireless device ID is found), the wireless device 515 may not realize that the second control signal 520 is intended for itself. Therefore, even when network entity 505 does not include a wake-up reason in the first control signal 510 (such as when network entity 505 may only include a specific device ID value as an indication to perform an inventory of all wireless devices 515 near reader device 515), reader device 550 can also include a wake-up reason in the second control signal 520 indicating that all nearby wireless devices 515 will be inventoried. By providing a wake-up reason in the second control signal 520, wireless device 515 can perform the inventory process without checking identification information (e.g., wireless device ID) used to identify wireless device 515.

[0100] Therefore, one or more wireless devices among the wireless devices 515 near the reader device 550 can detect or receive the second control signal 520. When a wireless device 515 detects the second control signal 520, the wireless device 515 can be triggered by a wake-up reason included in the second control signal 520. If the wake-up reason indicates "No AIoT Device ID" or "Paging without any ID" or another indication from the second control signal 520 to count all wireless devices 515 near the reader device 550, the wireless device 515 can perform an inventory process. The inventory process may involve the wireless device 515 transmitting feedback 530 to the reader device 550 in response to receiving the second control signal 520, and may be performed based on a specific wake-up reason included in the second control signal 520 or based on one or more other parameters included in the second control signal 520. The feedback 530 may include an indication of identification information for the wireless device 515, and may additionally or alternatively include contextual information associated with the wireless device 515.

[0101] In response to receiving feedback 530 from one or more wireless devices 515, reader device 550 may send a response message 540 to network entity 505. The response message 540 may respond to a first control signal 510 sent from network entity 505 to reader device 550 instructing the counting of wireless devices 515 near reader device 550. In some cases, the response message 540 may be about... Figure 3 The described success or failure message, and can be categorized by about Figure 3 The method described is used to determine this. In other cases, since a particular wireless device 515 is not the target of paging, the response message 540 may only include a list of the found wireless devices 515, relevant context information, and optionally context information of the reader device 550. Based on the received response message 540, the network entity 505 may have the inventory information stored, such as at the network entity 505 or at an AIoT server.

[0102] Figure 6 A block diagram 600 illustrates a device 605 supporting techniques for paging AIoT devices in a wireless communication system, according to one or more aspects of this disclosure. Device 605 may be an example of aspects of a UE 115, network entity 105, or base station 140 as described herein. Device 605 may include a receiver 610, a transmitter 615, and a communication manager 620. Device 605, or one or more components of device 605 (e.g., receiver 610, transmitter 615, communication manager 620), may include at least one processor that may be coupled to at least one memory to individually or jointly support or implement the described techniques. Each of these components may communicate with each other (e.g., via one or more buses).

[0103] Receiver 610 may provide components for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to technologies used for paging AIoT devices in wireless communication systems). The information may be passed to other components of device 605. Receiver 610 may utilize a single antenna or a collection of antennas.

[0104] Transmitter 615 may provide components for transmitting signals generated by other components of device 605. For example, transmitter 615 may transmit information associated with various information channels, such as control channels, data channels, and information channels related to technologies used for paging AIoT devices in wireless communication systems, including packets, user data, control information, or any combination thereof. In some examples, transmitter 615 may be co-located with receiver 610 in a transceiver module. Transmitter 615 may utilize a single antenna or a collection of multiple antennas.

[0105] The communication manager 620, receiver 610, transmitter 615, or various combinations or components thereof may be examples of components used to perform various aspects of the techniques described herein for paging AIoT devices in a wireless communication system. For example, the communication manager 620, receiver 610, transmitter 615, or various combinations or components thereof may be able to perform one or more of the functions described herein.

[0106] In some examples, the communication manager 620, receiver 610, transmitter 615, or various combinations or components thereof may be implemented in hardware (e.g., in communication management circuitry). The hardware may include at least one of the following: a processor, digital signal processor (DSP), central processing unit (CPU), graphics processing unit (GPU), neural processing unit (NPU), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA), or other programmable logic device, microcontroller, discrete gate or transistor logic component, discrete hardware component, or any combination thereof, configured as or otherwise individually or collectively to support components for performing the functions described herein. In some examples, at least one processor and at least one memory coupled to said at least one processor may be configured to perform one or more of the functions described herein (e.g., instructions stored in at least one memory are executed individually or collectively by one or more processors).

[0107] Additionally or alternatively, the communication manager 620, receiver 610, transmitter 615, or various combinations or components thereof may be implemented in code (e.g., as communication management software) executed by at least one processor (e.g., referred to as processor executable code). If implemented in code executed by at least one processor, the functionality of the communication manager 620, receiver 610, transmitter 615, or various combinations or components thereof may be performed by any combination of a general-purpose processor, DSP, CPU, GPU, NPU, ASIC, FPGA, microcontroller, or these or other programmable logic devices (e.g., configured as or otherwise individually or collectively to support components for performing the functions described in this disclosure).

[0108] In some examples, the communication manager 620 may be configured to use a receiver 610, a transmitter 615, or both, or otherwise cooperate with them to perform various operations (e.g., receiving, acquiring, monitoring, outputting, transmitting). For example, the communication manager 620 may receive information from the receiver 610, transmit information to the transmitter 615, or be integrated in combination with the receiver 610, the transmitter 615, or both to acquire information, output information, or perform various other operations as described herein.

[0109] The communication manager 620 can support wireless communication according to examples disclosed herein. For example, the communication manager 620 is capable of, configured to, or operable to support components for receiving a first control signal from a network entity, wherein the first control signal instructs a reader device to wake up one or more wireless devices different from the reader device. The communication manager 620 is capable of, configured to, or operable to support components for sending a second control signal to one or more wireless devices, the second control signal including identification information associated with one or more wireless devices, a wake-up reason, or both. The communication manager 620 is capable of, configured to, or operable to support components for sending a response message to a network entity after sending the second control signal.

[0110] By including or configuring a communication manager 620 according to an example as described herein, device 605 (e.g., controlling receiver 610, transmitter 615, communication manager 620, or a combination thereof, or at least one processor otherwise coupled to them) can support techniques for improving communication reliability and enhancing coordination between devices.

[0111] Figure 7 A block diagram 700 illustrates a device 705 supporting techniques for paging AIoT devices in a wireless communication system, according to one or more aspects of this disclosure. Device 705 may be an example of aspects of device 605 or UE 115 as described herein. Device 705 may include a receiver 710, a transmitter 715, and a communication manager 720. Device 705, or one or more components of device 705 (e.g., receiver 710, transmitter 715, communication manager 720), may include at least one processor that may be coupled to at least one memory to support the described techniques. Each of these components may communicate with each other (e.g., via one or more buses).

[0112] Receiver 710 may provide components for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to technologies used for paging AIoT devices in wireless communication systems). The information may be passed to other components of device 705. Receiver 710 may utilize a single antenna or a collection of antennas.

[0113] Transmitter 715 may provide components for transmitting signals generated by other components of device 705.

[0163] While aspects of LTE, LTE-A, LTE-A Pro, or NR systems may be described for illustrative purposes, and the terms LTE, LTE-A, LTE-A Pro, or NR may be used in most of the description, the techniques described herein are also applicable to networks outside of LTE, LTE-A, LTE-A Pro, or NR networks. For example, the techniques described are applicable to a variety of other wireless communication systems, such as Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, and other systems and radio technologies not explicitly mentioned herein.

A general-purpose processor may be a microprocessor, but in alternative embodiments, a processor may be any processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors combined with a DSP core, or any other such configuration). Any function or operation described herein that can be performed by a processor may be performed by multiple processors capable of performing the described function or operation individually or jointly.

[0166] The functionality described herein can be implemented using hardware, software (e.g., executed by a processor), or any combination thereof. Software should be broadly interpreted as instructions, instruction sets, code, code segments, program code, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, or functions, whether referred to as software, firmware, middleware, microcode, hardware description languages, or other terms. When implemented using software executed by a processor, the functionality can be stored as one or more instructions or code on a computer-readable medium or transmitted using one or more instructions or code on a computer-readable medium. Other examples and specific implementations are within the scope of this disclosure and the appended claims. For example, due to the nature of software, the functionality described herein can be implemented using software, hardware, hardwired (e.g., executed by a processor), or any combination thereof. Features implementing the functionality can also be physically located in various locations, including portions distributed such that the functionality is implemented at different physical locations.

[0167] Computer-readable media includes both non-transitory computer storage media and communication media, encompassing any medium that facilitates the transfer of a computer program from one location to another. Non-transitory storage media can be any available medium accessible by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, phase-change memory, compact disc (CD) ROM or other optical disc storage devices, magnetic disk storage devices or other magnetic storage devices, or any other non-transitory medium that can be used to carry or store desired program code components in the form of instructions or data structures, and accessible by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. Furthermore, any connection is appropriately referred to as computer-readable media. For example, if software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included within the definition of computer-readable media. As used herein, disks and optical discs include CDs, laser discs, optical discs, digital multifunction discs (DVDs), floppy disks, and Blu-ray discs. Disks can magnetically reproduce data, and optical discs can optically reproduce data using lasers. Combinations of the above are also included within the scope of computer-readable media. Any function or operation described herein that can be performed by memory can be performed by multiple memories capable of performing the described function or operation individually or jointly.

[0168] As used herein (including in the claims), the word "or" in an enumeration of items (e.g., including enumerations of items ending with phrases such as "at least one of..." or "one or more of...") indicates an inclusive enumeration, such that an enumeration of at least one of, for example, A, B, or C means, for example, A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Furthermore, as used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, an example step described as "based on condition A" could be based on both condition A and condition B without departing from the scope of this disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "at least partially based on". As used herein, when the term "and / or" is used in a list of two or more items, it means that any one of the listed items may be used alone, or any combination of two or more of the listed items may be used. For example, if a composition is described as containing components A, B and / or C, the composition may contain A alone; B alone; C alone; a combination of A and B; a combination of A and C; a combination of B and C; or a combination of A, B and C.

[0169] As used herein, including in claims, the article “a” preceding a noun is open-ended and is understood to refer to “at least one” or “one or more” of those nouns. Therefore, the terms “a,” “at least one,” “one or more,” and “at least one of one or more” are interchangeable. For example, where a claim enumerates “components” performing one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “component” having a characteristic or performing a function may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent references to a component introduced with the article “a” using the terms “the” or “the” can refer to any or all of the one or more components. For example, a component introduced with the article “a” can be understood to mean “one or more components,” and subsequent reference to “the component” in a claim can be understood as equivalent to referring to “at least one of the one or more components.” Similarly, subsequent references to a component introduced with the terms “the” or “the” as “one or more components” can refer to any or all of the one or more components. For example, reference to "the one or more components" in the subsequent claims can be understood as equivalent to reference to "at least one of the one or more components".

[0170] The terms "determine" or "identify" encompass a variety of actions, and therefore, "determine" or "identify" can include calculation, computation, processing, derivation, investigation, lookup (such as by searching in a table, database, or other data structure), ascertainment, etc. Additionally, "determine" or "identify" can include receiving (such as receiving information or signaling, e.g., receiving information or signaling for determination, receiving information or signaling for identification), accessing (such as accessing data in memory or accessing information), etc. Furthermore, "determine" or "identify" can include parsing, obtaining, selecting, choosing, creating, and other similar actions.

[0171] In the accompanying drawings, similar components or features may have the same reference numerals. Furthermore, various components of the same type can be distinguished by adding a dash after the reference numeral and a second reference numeral to differentiate between similar components. If only the first reference numeral is used in the description, the description applies to any of the similar components having the same first reference numeral, regardless of the second reference numeral or other subsequent reference numerals.

[0172] The description herein, illustrated with reference to the accompanying drawings, describes an example configuration and does not represent all achievable examples or those within the scope of the claims. The term "example" as used herein means "serving as an example, instance, or illustration," not "preferred" or "advantageous over other examples." The detailed description includes specific details used to provide an understanding of the described techniques. However, these techniques can be practiced without these specific details. In some of the drawings, known structures and devices are shown in block diagram form to avoid obscuring the concept of the described examples.

[0173] The description herein is provided to enable those skilled in the art to implement or use this disclosure. Various modifications to this disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the scope of this disclosure. Therefore, this disclosure is not limited to the examples and designs described herein, but should be granted the widest scope consistent with the principles and novel features disclosed herein.
