AI Technical Summary
Current techniques do not effectively support ambient Internet of Things (AIoT) device access and data reporting, particularly in wireless communications systems.
A query and response technique is implemented, where a reader wireless device transmits a first query message to energize AIoT devices, and upon receiving a first response message indicating a preamble for access, the device transmits a second query message for resource allocation, allowing the AIoT device to respond with an identifier and data using the allocated resource.
This technique enables efficient AIoT device access and data reporting by establishing a clear query and response mechanism for resource allocation, improving communication reliability and resource utilization in wireless communications systems.

These systems may be capable of supporting communication with multiple users by sharing the 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-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 spread orthogonal frequency division multiplexing (DFT-S-OFDM) . A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE) .SUMMARY

[0042] Some wireless communications systems may include ambient internet of things (AIoT) devices. AIoT devices may include various passive devices capable of energy harvesting by receiving power from transmissions by other devices. For instance, a radio reference (RF) source device or a reader wireless device may communicate with one or more AIoT devices, which may be referred to as tags, passive user equipment (PUEs) , or backscatter UEs (BUEs) . In some examples, the RF source device or reader wireless device may be a network entity or a user equipment (UE) . The reader wireless device may transmit a carrier wave, and the AIoT device may harvest energy from the transmitted carrier wave. Additionally, after harvesting sufficient power, the AIoT device may transmit data to the reader wireless device via a backscatter link to the reader wireless device. One problem for the communication between the reader wireless device and the AIoT device is the procedure and signaling for AIoT device access and data reporting. Current techniques may not support AIoT device access and data reporting.
[0043] Techniques for AIoT device access and data reporting may include a query and response convention. For example, the reader wireless device may transmit a first query message for energizing one or more AIoT devices within a coverage range of the reader wireless device. In some examples, the first query message may include wake up signaling, such as low power wake up signaling. An AIoT device that harvests sufficient energy from the first query message may transmit, to the reader wireless device, a first response message indicating a preamble for AIoT device access. In some examples, the first response message may include information indicating a class, a capacity, an energy status, and data requirement of the AIoT device. In some examples, the first response message is one of a group of predefined preamble messages, and each of the predefined preamble messages may indicate a class of the AIoT device, a capability of the AIoT device, an energy status, a data requirement, or a combination thereof.
[0044] The reader wireless device, in response to receiving the first response message from the AIoT device, may transmit a second query message to the AIoT device, and the second query message may indicate a resource allocation. In some examples, the reader wireless device may retransmit the second query message to the AIoT device after a defined duration of time. The AIoT device, in response to receiving the second query command, may transmit a second response message indicating an AIoT device identifier and data using a resource of the resource allocation. In some examples, the second response message may include information indicating a class, a capacity, an energy status, and data requirement of the AIoT device. In some examples, the reader wireless device may transmit an additional query command indicating a second resource allocation based on information of the second response message.
[0045] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are also described in context of a process flow and a resource allocation diagram. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques for AIoT device access and data reporting.
[0046] FIG. 1 shows an example of a wireless communications system 100 that supports techniques for AIoT device access and data reporting in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0047] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via one or more communication links 125 (e.g., a radio frequency (RF) access link) . For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs) .
[0048] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various types of devices, such as other UEs 115 or network entities 105, as shown in FIG. 1.
[0049] As described herein, a node of the wireless communications system 100, which may be referred to as a network node, or a 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, an apparatus, a device, a 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 a UE 115. As another example, a node may be a 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 a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network entity 105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.
[0050] In some examples, network entities 105 may communicate with the core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., in accordance with an S1, N2, N3, or other interface protocol) . In some examples, network entities 105 may communicate with one another via a backhaul communication link 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network entities 105) or indirectly (e.g., via a core network 130) . In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol) , or any combination thereof. The backhaul communication links 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link) , one or more wireless links (e.g., a radio link, a wireless optical link) , among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.
[0051] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB) , a 5G NB, a next-generation eNB (ng-eNB) , a Home NodeB, a Home eNodeB, or other suitable terminology) . In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140) .
[0052] In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) , which may be configured to utilize a protocol stack that is physically or logically distributed among two or more network entities 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, a network entity 105 may include one or more of a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN Intelligent Controller (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) 180 system, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations) . In some examples, one or more network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0053] The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3) , layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaption protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 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 the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU 165 and an RU 170 such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (e.g., via one or more RUs 170) . In some cases, a functional split between a CU 160 and a DU 165, or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170) . A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to one or more DUs 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to one or more RUs 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface) . In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that are in communication via such communication links.
[0054] In wireless communications systems (e.g., wireless communications system 100) , infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130) . In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as a donor entity or an IAB donor. One or more DUs 165 or one or more RUs 170 may be partially controlled by one or more CUs 160 associated with a donor network entity 105 (e.g., a donor base station 140) . The one or more donor network entities 105 (e.g., IAB donors) may be in communication with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120) . IAB nodes 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by DUs 165 of a coupled IAB donor. An IAB-MT may include an independent set of antennas for relay of communications with UEs 115, or may share the same antennas (e.g., of an RU 170) of an IAB node 104 used for access via the DU 165 of the IAB node 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB nodes 104 may include DUs 165 that support communication links with additional entities (e.g., IAB nodes 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream) . In such cases, one or more components of the disaggregated RAN architecture (e.g., one or more IAB nodes 104 or components of IAB nodes 104) may be configured to operate according to the techniques described herein.
[0055] In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support techniques for AIoT device access and data reporting as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., IAB nodes 104, DUs 165, CUs 160, RUs 170, RIC 175, SMO 180) .
[0056] A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples.
[0057] The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.
[0058] The UEs 115 and the network entities 105 may wirelessly communicate with one another via one or more communication links 125 (e.g., an access link) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for a communication link 125 may include a portion of a RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information) , control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub- entity) of a network entity 105. For example, the terms “transmitting, ” “receiving, ” or “communicating, ” when referring to a network entity 105, may refer to any portion of a network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105) .
[0059] Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM) ) . In a system employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both) , such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam) , and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.
[0060] The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of Ts=1 / (Δfmax·Nf) seconds, for which Δfmax may represent a supported subcarrier spacing, and Nf may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms) ) . Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023) .
[0061] Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communications systems 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., Nf) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.
[0062] A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI) . In some examples, the TTI duration (e.g., a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) ) .
[0063] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET) ) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs) ) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to multiple UEs 115 and UE-specific search space sets for sending control information to a specific UE 115.
[0064] In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, the overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.
[0065] Some UEs 115, such as MTC or IoT devices, may be low cost or low complexity devices and may provide for automated communication between machines (e.g., via Machine-to-Machine (M2M) communication) . M2M communication or MTC may refer to data communication technologies that allow devices to communicate with one another or a network entity 105 (e.g., a base station 140) without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application program that uses the information or presents the information to humans interacting with the application program. 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 business charging.
[0066] The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC) . The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication 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 prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.
[0067] In some examples, a UE 115 may be configured to support communicating directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., in accordance with a peer-to-peer (P2P) , D2D, or sidelink protocol) . In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of a network entity 105 (e.g., a base station 140, an RU 170) , which may support aspects of such D2D communications being configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may support a one-to-many (1: M) system in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity 105.
[0068] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.
[0069] The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from 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 the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.
[0070] The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) radio access technology, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA) . Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
[0071] A network entity 105 (e.g., a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entity 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations 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, antennas or antenna arrays associated with a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.
[0072] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .
[0073] The wireless communications system 100 may include AIoT devices. AIoT devices may include various passive devices capable of energy harvesting by receiving power from transmissions by other devices. For instance, a radio reference (RF) source device or a reader wireless device may communicate with one or more AIoT devices, such as tags. In some examples, the RF source device or reader wireless device may be a network entity 105 or a UE 115. The reader wireless device may transmit a carrier wave, and the AIoT device may harvest energy from the transmitted carrier wave. Additionally, after harvesting sufficient power, the AIoT device may transmit data to the reader wireless device via a backscatter link to the reader wireless device. One problem for the communication between the reader wireless device and the AIoT device is the procedure and signaling for AIoT device access and data reporting. Current techniques may not support AIoT device access and data reporting.
[0074] Techniques for AIoT device access and data reporting may include a query and response technique. For example, the reader wireless device may transmit a first query message for energizing one or more AIoT devices within a coverage range of the reader wireless device. In some examples, the first query message may include wake up signaling, such as low power wake up signaling. An AIoT device that harvests sufficient energy from the first query message may transmit, to the reader wireless device, a first response message indicating a preamble for AIoT device access. In some examples, the first response message may include information indicating a class, a capacity, an energy status, and data requirement of the AIoT device. In some examples, the first response message is one of a group of predefined preamble messages, and each of the predefined preamble messages may indicate a class of the AIoT device, a capability of the AIoT device, an energy status, a data requirement, or a combination thereof.
[0075] The reader wireless device, in response to receiving the first response message from the AIoT device, may transmit a second query message to the AIoT device, and the second query message may indicate a resource allocation. In some examples, the reader wireless device may retransmit the second query message to the AIoT device after a defined duration of time. The AIoT device, in response to receiving the second query command, may transmit a second response message indicating an AIoT device identifier and data using a resource of the resource allocation. In some examples, the second response message may include information indicating a class, a capacity, an energy status, and data requirement of the AIoT device. In some examples, the reader wireless device may transmit an additional query command indicating a second resource allocation based on information of the second response message.
[0076] FIG. 2 shows an example of a wireless communications system 200 that supports techniques for AIoT device access and data reporting in accordance with one or more aspects of the present disclosure. The wireless communications system 200 may implement aspects of or may be implemented by aspects of the wireless communications system 100. For example, the wireless communications system 200 includes a UE 115-a, which may be an example of a UE 115 as described herein. The wireless communications system 200 may also include a network entity 105-a, which may be an example of a network entity 105 as described herein. The wireless communications system 200 also includes an AIoT device 205-a and an AIoT device 205-b.
[0077] The AIoT device 205-a may communicate with the network entity 105-a using a communication link 125-b, and the UE 115-a may communicate with the network entity 105-a using a communication link 125-a. The communication link 125-b may be an example of an NR or LTE link between the AIoT device 205-a and the network entity 105-a. The communication link 125-a may be an example of an NR or LTE link between the UE 115-a and the network entity 105-a. The communication link 125-a and the communication link 125-b may include bi-directional links that enable both uplink and downlink communications. For example, the AIoT device 205-a may transmit uplink signals (e.g., uplink transmissions) , such as uplink control signals or uplink data signals, to the network entity 105-a using the communication link 125-b and the network entity 105-a may transmit downlink signals (e.g., downlink transmissions) , such as downlink control signals or downlink data signals, to the AIoT device 205-a using the communication link 125-b. The UE 115-a may transmit uplink signals (e.g., uplink transmissions) , such as uplink control signals or uplink data signals, to the network entity 105-a using the communication link 125-a and the network entity 105-a may transmit downlink signals (e.g., downlink transmissions) , such as downlink control signals or downlink data signals, to the UE 115-a using the communication link 125-a.
[0078] The AIoT device 205-a may communicate with the UE 115-a using communication link 135-a, and the AIoT device 205-b may communicate with the UE 115-a using communication links 135-b, which may be examples of a communication link 135 as described herein. For example, the communication link 135-a and the communication link 135-b may be a sidelink communication link and may support bidirectional communications between the AIoT device 205-a and the UE 115-a and the AIoT device 205-b and the UE 115-a.
[0079] The AIoT device 205-a and the AIoT device 205-b may be examples of ultra-low complexity and ultra-low power devices providing complexity and power consumption orders of magnitude lower than existing enhanced Machine Type Communication (eMTC) devices and narrow band internet of things (NB-IoT) devices. One example of the AIoT device 205-a and the AIoT device 205-b may be a type A battery-less device with no energy storage capability that may be completely dependent on the availability of an external source of energy. Another example of the AIoT device 205-a and the AIoT device 205-b may be a type B device with limited energy storage capability, such as super capacity or conventional capacity that does not have to be replaced or recharged manually.
[0080] In some examples, the AIoT device 205-a and the AIoT device 205-b may be a device known as a tag, a backscatter UE (BUE) or a passive UE (PUE) that is a passive device without active RF components. The PUE may perform data transmission based on modulating the incident RF signals emitted by an ambient transmitter, such as UE 115-a or network entity 105-a. The ambient RF signals may serve as a signal resource for backscattering and as energy resources for harvesting. A radio frequency identification device (RFID) is an example of an existing battery-less technology with a reading range of a few meters.
[0081] In some examples, the AIoT device 205-a and the AIoT device 205-b may harvest energy from different sources, such as a dedicated RF source, an ambient RF source, or environmental conditions such as solar energy. In some examples, the UE 115-a may be the RF source for the AIoT device 205-a and the AIoT device 205-b, and the network entity 105-a may be the RF source for the AIoT device 205-a. The UE 115-a may transmit a carrier wave to the AIoT device 205-a and the AIoT device 205-b, and the AIoT device 205-a and the AIoT device 205-b may harvest energy from the carrier wave transmitted by the UE 115-a. The network entity 105-a may transmit a carrier wave to the AIoT device 205-a, and the AIoT device 205-a may harvest energy from the carrier wave.
[0082] In some examples, the UE 115-a may be a reader of the AIoT device 205-a and the AIoT device 205-b, and the network entity 105-a may be a reader for the AIoT device 205-a. The reader wireless device (e.g., UE 115-a and network entity 105-a) may perform a signaling procedure for AIoT device (e.g., AIoT device 205-a and AIoT device 205-b) access and for data reporting from the AIoT device (e.g., AIoT device 205-a and AIoT device 205-b) to the reader wireless device (e.g., UE 115-a and network entity 105-a) . The AIoT device 205-a and the AIoT device 205-b may be within a coverage area 240 of the UE 115-a to receive energy from the UE 115-a. In some cases, the AIoT device may be called a tag, the AIoT device access may be called tag access, and the AIoT device reporting may be called tag data reporting. In some examples, the signal procedure for the AIoT device access phase and for data reporting phase may include a query and response model with multiple rounds of query messages transmitted by the reader wireless device and multiple response messages transmitted by the AIoT device. In some cases, power boosting and query message repetition may be enabled during tag access and data reporting.
[0083] Referring to FIG. 2, the UE 115-a, performing as the reader, may transmit a first query message 215-a to the AIoT device 205-a via link 135-a, and the AIoT device 205-a may transmit a first response message 220-a to the UE 115-a. In response to receiving the first response message 220-a, the UE 115-a may transmit one or more second query messages 225-a to the AIoT device 205-a via link 135-a, and the AIoT device 205-a may transmit one or more second first response messages 230-a to the UE 115-a. Similarly, the UE 115-a, performing as the reader, may transmit a first query message 215-b to the AIoT device 205-b via link 135-b, and the AIoT device 205-b may transmit a first response message 220-b to the UE 115-a. In response to receiving the first response message 220-b, the UE 115-a may transmit one or more second query messages 225-b to the AIoT device 205-b via link 135-b, and the AIoT device 205-b may transmit one or more second first response messages 230-b to the UE 115-a. In some cases, the network entity 105-a, performing as the reader, may transmit a first query message 215-c to the AIoT device 205-a via link 125-a, and the AIoT device 205-a may transmit a first response message 220-c to the network entity 105-a. In response to receiving the first response message 220-c, the network entity 105-a may transmit one or more second query messages 225-c to the AIoT device 205-a via link 125-b, and the AIoT device 205-a may transmit one or more second first response messages 230-c to the network entity 105-a. In some cases, the network entity 105-a may transmit a query message 210, to the UE 115-a via the link 125-a, informing the UE 115-a to perform as a reader, and the UE 115-a may transmit a message 235 indicating AIoT data to the network entity 105-a via the link 125-a.
[0084] FIG. 3 shows an example of a process flow 300 that supports techniques for AIoT device access and data reporting in accordance with one or more aspects of the present disclosure. In some examples, the process flow 300 may implement or be implemented by aspects of the wireless communications systems 100 and 200 as described with reference to FIGs. 1 and 2, respectively. For example, the process flow 300 may be implemented by a network entity 105-b, which may be an example of the network entities 105 as described with reference to FIGs. 1 and 2. The process flow 300 may be implemented by an AIoT device 205-c, which may be an example of the AIoT device 205-a and the AIoT device 205-b as described with reference to FIG. 2. The process flow 300 may be implemented by a reader wireless device 305, which may be an example of the network entities 105 and the UEs 115 as described with reference to FIGs. 1 and 2, respectively, or some other wireless device. The example with the network entity 105 as the reader may be call topology one, and the example with the UE 115 as the reader may be called topology two.
[0085] In some examples, the operations illustrated in process flow 300 may be performed by hardware (e.g., including circuitry, processing blocks, logic components, and other components) , code (e.g., software executed by a processor) , or any combination thereof. Alternative examples of the following may be implemented, where some steps are performed in a different order than described or are not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added.
[0086] At 310, the reader wireless device 305 may receive, from the network entity 105-b, a query message or query command to inform the reader wireless device 305 to query AIoT devices. In some examples, the query message, received the by the reader wireless device 305 from the network entity 105-b, may inform the reader wireless device 305 to transmit a first query message, as described herein, to one or more AIoT devices within a coverage area of the reader wireless device 305. In some examples, the query message received by the reader wireless device 305 from the network entity 105-b may include a resource configuration for the reader wireless device 305 to communicate with the one or more AIoT devices. For example, the network entity 105-b may preconfigure the reader wireless device 305 for communication with the AIoT devices. In some examples, the query message may be a paging-like message.
[0087] At 315, the reader wireless device 305 may transmit a first query message or first query command associated with energizing to one or more AIoT devices (e.g., the AIoT device 205-c) within a coverage range of the reader wireless device 305. In some examples, the first query message may include a wake-up like signal, such as low power wake up signaling (LP-WUS) . The first query message may be an energy source for the AIoT devices (e.g., AIoT device 205-c) within the coverage range of the reader wireless device 305. The AIoT devices (e.g., AIoT device 205-c) within the coverage range of the reader wireless device 305 may harvest energy from the first query message to be energized into an operating state.
[0088] At 320, the reader wireless device 305 may receive, from the AIoT device 205-c of the one or more AIoT devices, a first response message indicating a preamble for AIoT device access. The AIoT device 205-c may harvest sufficient energy from the first query message and successfully received the first query message. In some cases, a set of AIoT devices may each harvest enough energy and successfully receive the first query message and transmit the first response message. The first response message may also be considered as an initial tag response. The first response message may indicate a tag preamble-like message for AIoT device access and for congestion avoidance. In some cases, the first response message may be similar or analogous to a message one (msg1 or msgA) physical random access channel (PRACH) preamble transmitted by a UE to initiate the random access process for connecting to a network entity via a Uu interface. The first response message may be similar to the PRACH preamble because the purpose of first response message (e.g., tag preamble-like message) is the same as purpose of the PRACH preamble. That is, the purpose of the first response message may be for tag access, congestion avoidance, and for the reader wireless device to detect the AIoT device. The first response message may be different from the PRACH preamble. For example, a waveform of the first response message and a possible sequence / length of the first response message may be different from a waveform and a sequence / length of the legacy PRACH preamble. Additionally, the whole physical channel of the first response message may be different from the physical channel of the legacy PRACH preamble.
[0089] In some examples, the preamble of the first response message may indicate a class of the AIoT device 205-c, a capability of the AIoT device 205-c, an energy status of the AIoT device 205-c, a data requirement or combination thereof. In some examples, the first response message may be one of a group of predefined preamble messages. Each of the predefined preamble messages may indicate a class of the AIoT device 205-c, a capability of the AIoT device 205-c, an energy status of the AIoT device 205-c, a data requirement or combination thereof.
[0090] At 325, the reader wireless device 305 may transmit, to the AIoT device 205-c in response to receiving the first response message, a second query message or command indicating a resource allocation. In some examples, the reader wireless device 305 may allocate the resources to the detected AIoT devices (e.g., AIoT device 205-c) whose tag preamble-like has been successfully received by reader wireless device 305. The resource may be pre-configured by the network entity 105-b. The resources may be allocated to the detected AIoT devices and congestion avoidance may be considered. In some cases, the resource allocation may be a contention-free resource or a contention-based resource. In some cases, the second query message may be similar or analogous to a message two (msg2) of the random access channel (RACH) procedure received by a UE as part of the random access process for connecting to a network entity via a Uu interface. The second query message may be similar to the message two of the RACH procedure because the purpose of second query message is the same as purpose of the PRACH preamble. That is, the purpose of the second query message may be to allocate the resource for the AIoT device to report AIoT data similar as the resource allocation function of the uplink grant in the message two random access response (RAR) of the RACH procedure. The second query message may be different from the message two of the RACH procedure as the AIoT does not have the random access response message. The resource allocation of the second query message may be different from the format of the uplink grant in the message two RAR.
[0091] At 330, the AIoT device 205-c may transmit, to the reader wireless device 305, a second response message indicating an AIoT device identifier and AIoT device data. The second response message is transmitted on a resource corresponding to the resource allocation. In some examples, the second response message includes indication information indicating a class of the AIoT device 205-c, a capability of the AIoT device 205-c, an energy status of the AIoT device 205-c, a data requirement or combination thereof.
[0092] At 335, the reader wireless device 305 may transmit, to the AIoT device 205-c a query message or command indicating a resource allocation. In some examples, the reader wireless device 305 may retransmit the second query message based on a failure of the reader wireless device 305 to receive the second response message. In some cases, the reader wireless device 305 may retransmit the second query message after a defined duration of time. In some examples, the reader wireless device 305 may transmit a query message indicating a second resource allocation based on the indication information received in the second response message.
[0093] At 340, the AIoT device 205-c may transmit, to the reader wireless device 305 a response message indicating an AIoT device identifier and AIoT device data using a resource of the resource allocation included in the query message at 335. In some examples, response message includes indication information indicating a class of the AIoT device 205-c, a capability of the AIoT device 205-c, an energy status of the AIoT device 205-c, a data requirement or combination thereof.
[0094] At 345, the reader wireless device 305 may transmit, to the AIoT device 205-c, a query message or command indicating a resource allocation for tag data reporting.
[0095] At 350, the AIoT device 205-c may transmit, to the reader wireless device 305 a response message indicating an AIoT device identifier and AIoT device data using a resource of the resource allocation included in the query message. In some examples, response message includes indication information indicating a class of the AIoT device 205-c, a capability of the AIoT device 205-c, an energy status of the AIoT device 205-c, a data requirement or combination thereof.
[0096] Together, the first query message at 315, the first response message at 320, the second query message at 325, and the second response message at 330 may be considered as the AIoT device access phase or tag access phase. Together, the query message at 335 and the response message may be considered as the AIoT device data reporting phase or tag data reporting phase. The query message at 345 and the response message at 350 may be considered as the AIoT device data reporting phase or tag data reporting phase. In the data reporting phase, the reader wireless device 305 may transmit multiple rounds of query messages for large AIoT data. The AIoT device 205-c may use tag information to indicate the tag data requirements in the response message. The reader wireless device 305 may provide the resource allocation to the AIoT device 205-c based on the tag data requirements. The query message or command at 315, 325, 335 and 345 may indicate actions to the AIoT device 205-c, such as wake-up of the first query message at 315, resource allocation of the second query message at 325, report tag data of the query messages at 335 and 345. The query messages may include field that indicates the action command.
[0097] At 355, the reader wireless device 305 may transmit, to the network entity 105-b, the AIoT device 205-c data. In some examples, the reader wireless device 305 may reassemble the AIoT device data or tag data as UE data prior to transmitting to the network entity 105-b. In some cases, the reader wireless device 305 may transmit, to the network entity 105-b, the AIoT device data from several AIoT devices to the network entity, and the respective AIoT device data may be associated with the respective AIoT device identifier.
[0098] In some examples, the reader wireless device 305 may determine a quantity of AIoT devices within the coverage range of the reader wireless device 305 in response to receiving a quantity first response messages from the one or more AIoT devices. The reader wireless device 305 may determine the resource allocation for the second query message and the data reporting query messages based on the quantity of AIoT devices. For example, the quantity of detected AIoT devices may affect the contention-based resource allocation. The second query message in the tag access phase and the query message in the tag data reporting phase may indicate the resource allocation to the detected or selected AIoT devices. The reader wireless device 305 may allocate the resources, provided by the network entity 105-b, to the detected or selected AIoT devices in the tag access phase and the tag data reporting phase. In the tag data reporting phase, in each query message, the reader wireless device 305 may indicate the resource for AIoT data reporting. The allocated resource may be contention-based resource configured for a set of detected or selected AIoT devices or may be contention-free resource associated to one of the AIoT devices to avoid congestion. If the quantity of detected or selected AIoT devices is large, such as larger than the available resources, the reader wireless device 305 may configure contention-based resources for the AIoT devices without associating a resource to one of the AIoT devices. If the quantity of detected or selected AIoT devices is equal to or less than the quantity of available resources, the reader wireless device 305 may configure contention-free resources for the AIoT devices. The contention-free resource may be more efficient for fast AIoT data delivery. The contention-free resource is associated to one of the selected identified AIoT devices.
[0099] FIG. 4 shows an example of a resource allocation diagram 400 that supports techniques for AIoT device access and data reporting in accordance with one or more aspects of the present disclosure. In some examples, the resource allocation diagram 400 may implement or be implemented by aspects of the wireless communications systems 100 and 200 as described with reference to FIGs. 1 and 2, respectively. For example, the resource allocation diagram 400 may be implemented by a reader wireless device, which may be an example of the reader wireless device as described with reference to FIG. 2.
[0100] In some examples, the resource allocation diagram 400 includes a resource 405-a, a resource 405-b, a resource 405-c, a resource 405-d, a resource 405-e, and a resource 405-f. The resource 405-a, the resource 405-b, the resource 405-c, the resource 405-d, the resource 405-e, and the resource 405-f may represent the resource configuration indicated by the network entity 105-b to the reader wireless device 305. In some examples, the reader wireless device 305 may associate a contention-free resource (e.g., resource 405-a) to the AIoT device 205-c, and the reader wireless device 305 may associate a contention free resource (e.g., resource 405-d) to another detected AIoT device. In another example, the reader wireless device 305 may associate the contention-based resources (e.g., resource 405-a, resource 405-b, resource 405-c, resource 405-d, resource 405-e, and resource 405-f) to detected AIoT devices. The contention-based resource allocation may allow the AIoT device 205-c to select one of the resources from the pool of resources (e.g., resource 405-a, resource 405-b, resource 405-c, resource 405-d, resource 405-e, and resource 405-f) shared with other AIoT devices.
[0101] In some examples, the reader wireless device 305 may determine the quantity of AIoT devices within the coverage range of the reader wireless device 305 in response to receiving the quantity first response messages from the one or more AIoT devices. For example, the reader wireless device 305 may detect three AIoT devices (e.g., tag1, tag2 and tag2) . For the second query message, the reader wireless device 305 may determine a resource allocation 410 with a first contention-free resource associated to tag1, a second contention-free resource associated to tag2, a third contention-free resource associated to tag3 and the remaining resources being contention-based resources.
[0102] In some cases, the reader wireless device 305 may assign the dedicated resource to the AIoT device 205-c for the tag response message. If the AIoT device 205-c indicates additional data to report during the query session via the response message, the reader wireless device 305 may assign a dedicated resource to the AIoT device 205-c for the response message providing the data. In some cases, the reader wireless device 305 may assign the resource in time division multiplexing (TDM) , frequency division multiplexing (FDM) and space division multiplexing (SDM) means to the AIoT device 205-c. For example, the resource allocated to AIoT device 205-c may be distributed in a time domain to reduce collisions when multiple AIoT devices respond with the response messages in the allocated resource. In another example, the resource allocated to AIoT device 205-c may be frequency shifted in backscatter for AIoT data reporting. The resource configuration in terms of time, frequency or beam domain may be provided by the network entity 105-b as the resource pre-configuration.
[0103] In some examples, the AIoT device 205-c may implicitly indicate its class, capability, energy status, data requirement or combination thereof using the preamble or preamble-like of the first response message. In some examples, the first response message may be one of a group of predefined preamble messages. Each of the predefined preamble messages may indicate the class, the capability, the energy status, the data requirement, or a combination thereof. In some cases, the AIoT device 205-c may be configured with a partitioning pool of predefined preamble or preamble-like message. The preamble messages may be group-based and may be configured by network entity 105-b. The AIoT device may select which groups of preamble messages to implicitly indicate its class, capability, energy status, data requirement or combination thereof. In some cases, the AIoT devices that indicate the advanced capability may be assigned a dedicated resource with frequency shift in backscatter or more resource (e.g., longer time slot) for larger AIoT data reporting.
[0104] In some cases, the implicit indication may be served as early indication for improved resource allocation from reader wireless device 305. The preamble or preamble-like group may be based on different AIoT data sizes, whether the AIoT device supports frequency shift in backscatter, whether the AIoT device supports multi- slot transmission, or whether the AIoT device is an active or passive AIoT. For example, if the AIoT device has a potential large amount AIoT data to be sent to the reader wireless device 305, the AIoT device may select the preamble or preamble-like group associated with the large AIoT data size.
[0105] In some cases, the reader wireless device 305 may not be able to determine whether all AIoT devices in the coverage area have completed their respective data reporting. The reader wireless device 305 may be unable to determine which AIoT devices in the coverage area may have data to report. Additionally, the AIoT devices may be in an instantaneous bad radio condition which causes less harvested energy and erroneous transmission. In some examples, autonomous transmission of the query messages may help the AIoT devices to harvest the power, to acquire the resource and to recover the failed transmission. A timer (e.g., query message retransmission timer) may be introduced to control the query message auto-transmission in tag data reporting phase. When the second query message is sent, the query retransmission timer may start. The reader wireless device 305 may decide whether to transmit additional query messages after the second query message has been transmitted. For example, the AIoT device 205-c may indicates in the second response message or later response messages that more pending AIoT data is to be sent by using the tag information indication. In some cases, a quantity of AIoT devices may indicate more pending data to send by using tag information indication in the second response message or later response messages. When the query retransmission timer expires, the reader wireless device 305 may autonomously transmit the query command indicating the resource allocation.
