[0003] The following content relates to wireless communication, including environmental Internet of Things (IoT) tag information indication. Background Technology

[0004] 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).

[0005] In some cases, wireless communication systems may include one or more devices with energy harvesting (EH) capabilities, such as environmental Internet of Things (IoT) tag devices, capable of wireless power transfer. Such EH-capable devices may be powered by reader wireless devices to transmit data generated by the EH-capable devices (e.g., sensor data, location data, tracking data, etc.). Summary of the Invention

[0006] The described technology relates to improved methods, systems, devices, and apparatuses for supporting the indication of information from environmental Internet of Things (IoT) tags. For example, the described technology provides a device with energy harvesting (EH) capability, such as an environmental IoT tag, for conveying an information indicator indicating the status of the EH-capable device, the status of data generated by the EH-capable device, or both.

For example, the EH-capable device may send a response message in response to the query command, the response message including an identifier of the EH-capable device, at least a portion of the data generated by the EH-capable device, and the information indicator. The information indicator may indicate the number of segments associated with the data (e.g., if the EH-capable device generates more data than permitted by the query command), a trigger for conveying the information indicator, parameters of the data (e.g., the type of data, the size of the data), or any combination thereof, and other examples.

[0049] In some wireless communication systems, devices with energy harvesting (EH) capabilities (such as environmental Internet of Things (IoT) devices) can use backscatter communication techniques to communicate with reader wireless devices. For example, an EH-capable device can modulate an event signal transmitted by a reader wireless device to convey information to that device while simultaneously harvesting energy from the event signal (e.g., to support subsequent communication). Such event signals may include a query command that the reader wireless device can send to one or more EH-capable devices. The query command may include a request for one or more EH-capable devices to send a response message in response to the query command, the response message including data generated by the EH-capable device (e.g., enriched data). In some cases, the EH-capable device receiving the query command may lack the energy to respond to the reader wireless device, may generate more data than the number of bits permitted by the query command, may generate additional data after the response message is sent, or any combination thereof. However, the EH-capable device may be unable to indicate such information to the reader wireless device, thus limiting the communication capabilities of the EH-capable device.

[0050] To support the synchronization of the status of an EH-capable device or data generated by such a device between an EH-capable device and a reader wireless device, the EH-capable device may include an information indicator with a response message to the reader wireless device. For example, in response to a group query from the reader wireless device, the EH-capable device may send a response message including an identifier of the EH-capable device, at least a portion of the data generated by the EH-capable device in response to the query command, and an information indicator associated with the EH-capable device. In some cases, the information indicator may indicate the transmission status of the data. For example, the information indicator may indicate the number of segments associated with the data based on the size of the data and the number of bits granted by the query command. In such cases, the reader wireless device may send (e.g., device-specific) one or more subsequent query commands, thereby granting the EH-capable device transmission resources for the corresponding segments of data to be transmitted via one or more subsequent response messages. Additionally or alternatively, the information indicator may indicate a trigger for sending the information indicator to an EH-enabled device, information associated with data (e.g., the type or size of the data), a request for transmission resources to communicate the data, or any combination thereof. By communicating the information indicator, EH-enabled devices can improve data communication with reader wireless devices.

[0051] The various aspects of this disclosure are first described in the context of a wireless communication system. These aspects are further illustrated and described by way of process flow. The various aspects of this disclosure are further illustrated and described by way of device diagrams, system diagrams, and flowcharts relating to environmental IoT tag information indication.

[0052] Figure 1 An example of a wireless communication system 100 indicated by IoT tag information supporting one or more aspects of this disclosure is shown. The wireless communication 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 communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro 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.

[0053] 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 one or more communication links 125 (e.g., radio frequency (RF) access links). 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 one or more communication links 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).

[0054] 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 Some example UE 115s are illustrated herein. The UE 115 described herein can be able to support various types of devices (such as, e.g., ...). Figure 1 It communicates with other UEs (115 or network entity 105) as shown.

[0055] As described herein, nodes of the wireless communication system 100 (which may be referred to as network nodes or wireless nodes) may be network entity 105 (e.g., any network entity described herein), UE 115 (e.g., any UE described herein), 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. Alternatively, a node may be network entity 105. Furthermore, a first node may be configured to communicate with a second or 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.

[0056] 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 one or more backhaul communication links 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 links 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. Backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, fiber optic links), one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 can communicate with core network 130 via communication link 155.

[0057] One or more network entities in network entity 105 described herein 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 that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as base station 140).

[0058] 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 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, network entity 105 may include one or more of the following: 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, a non-real-time RIC), a service management and orchestration (SMO) 180 system, or any combination thereof. 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 105 in a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0059] 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, and 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 higher protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionalities and signaling (e.g., Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). CU 160 can connect to one or more DU 165 or RU 170, and one or more DU 165 or RU 170 can 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 each can be at least partially controlled by CU 160. Additionally or alternatively, a protocol stack functional split can be employed between DU 165 and RU 170, such that DU 165 can support one or more layers of the protocol stack, and RU 170 can support one or more different layers of the protocol stack. DU 165 can support one or more different cells (e.g., via one or more RU 170). 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 different 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 one or more DU 165 via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to one or more 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 the corresponding network entities 105 communicating via such communication links.

[0060] In a wireless communication system (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 105 (e.g., IAB node 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DU 165s or one or more RU 170s may be partially controlled by one or more CU 160s associated with donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (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 a DU 165 of a coupled IAB donor. The IAB-MT may include 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 a DU 165 that supports 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., one or more IAB nodes 104 or components of IAB node 104) may be configured to operate according to the techniques described herein.

[0061] In the context of applying the techniques described herein to a decomposed RAN architecture, one or more components of the decomposed RAN architecture can be configured to support environmental IoT tag information indication as 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., IAB node 104, DU 165, CU 160, RU 170, RIC 175, SMO 180).

[0062] 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 a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. 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, meters, etc.

[0063] The UE 115 described herein can communicate with various types of devices, such as other UEs 115 that sometimes act as relays, network entities 105, and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc. Figure 1 As shown.

[0064] UE 115 and network entity 105 can wirelessly communicate with each other via one or more communication links 125 (e.g., 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 physical 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 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 coordinating carrier operation, 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 may be configured with 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, CU160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities 105).

[0065] 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, in which case 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 may 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.

[0066] The time interval for network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period. seconds, of which It can represent the supported subcarrier spacing, and This can represent the supported Discrete Fourier Transform (DFT) size. The time interval of the 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).

[0067] 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 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.

[0068] 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)).

[0069] 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 multiple UEs 115, and a UE-specific search space set used to transmit control information to a specific UE 115.

[0070] 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 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, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 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 radio access technologies to provide coverage for various coverage areas 110.

[0071] Some UE 115 devices (such as MTC or IoT devices) can be 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 entity 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 UE 115 devices 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 geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial toll collection.

[0072] 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 involve concurrent transmission and reception). In some examples, half-duplex communication can be performed at a reduced peak rate. Other power-saving techniques for UE 115s 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.

[0073] 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 or 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 prioritization of 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.

[0074] In some examples, UE 115 may be configured to support direct communication with other UE 115s via device-to-device (D2D) communication link 135 (e.g., according to peer-to-peer (P2P), D2D, or sidelink protocols). In some examples, one or more UE 115s performing D2D communication in a group 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 UE 115s in such a 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, the group of UE 115s communicating via D2D communication may support a one-to-many (1:M) system, where each UE 115 transmits to each of the other UE 115s in the group. In some examples, network entity 105 may facilitate the scheduling of resources used for D2D communication. In other examples, D2D communication may be performed between UEs 115 without involving network entity 105.

[0075] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-vehicle (V2X) communication, vehicle-to-vehicle (V2V) communication, or a combination of these. Vehicles may signal information related to traffic conditions, signal control, weather, safety, emergencies, or any other information relevant to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., network entity 105, base station 140, RU 170) using vehicle-to-network (V2N) communication, or both.

[0076] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 may 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 delivered through the user plane entity, which provides IP address allocation and other functions. The user plane entity may 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.

[0077] 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 100 km).

[0078] Wireless communication system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology. 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 bands may be combined with component carriers operating with licensed bands based on carrier aggregation configurations (e.g., LAA). Operation using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0079] 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.

[0080] 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).

[0081] In some examples of the wireless communication system 100, UE 115 may be an example of an EH-capable device, such as an environmental IoT device. In some cases, an EH-capable device may be an example of an ultra-low complexity and ultra-low power device (e.g., offering several orders of magnitude lower complexity and power consumption compared to other low-complexity devices such as enhanced MTC (eMTC) devices or narrowband IoT (NB-IoT) devices). For example, such an EH-capable device may not be able to perform energy storage (e.g., a Type A battery-free device that relies on the availability of an external power source) or may support limited energy storage (e.g., a Type B battery-free device that supports super-capacity or regular capacity, which does not require manual replacement or charging). In some cases, an EH-capable device (which may be referred to as a tag, backscatter UE (BUE), or passive UE (PUE)) may be a passive device (e.g., not equipped with active RF components) and may perform data transmission by modulating event RF signals transmitted by a reader wireless device (e.g., an environmental transmitter such as another UE 115 or network entity 105). For example, devices with EH capabilities can use ambient RF signals as a resource for backscatter communication, for energy harvesting, or both. RFID communication can be an example of environmental IoT communication using battery-free technology. However, such RFID communication may have a limited read range (e.g., a few meters) compared to other IoT devices using active backscatter, which poses challenges in supporting large-scale deployment of RFID tags and providing RFID tag coverage.

[0082] In some examples, an EH-capable device can use backscatter communication techniques to transmit data to a reader wireless device via a backscatter link (e.g., performing information transmission using antenna modulation without active RF generation). In some such examples, an EH-capable device can tune the antenna's reflection coefficient by switching between a set of impedances (e.g., a given set of impedances), allowing the EH-capable device to backscatter different amounts of event signals. For example, if the EH-capable device uses binary phase-shift keying (BPSK) modulation, it can switch the antenna's load impedance between a relatively high impedance and a relatively matched load. Thus, the EH-capable device can reflect all the power of the event signal back to the reader (e.g., when a relatively high impedance is applied), or it can collect the power of the event signal (e.g., when a relatively matched load is applied) to indicate a binary value back to the reader. In some cases, the frequency of impedance switching can be based on the data rate of communication between the EH-capable device and the reader.

[0083] In some cases, a reader wireless device may send a query command to an EH-enabled device (or a group of EH-enabled devices including that EH-enabled device), requesting a response from the EH-enabled device. Such a response message may include the identifier of the EH-enabled device and data generated by the EH-enabled device in response to the query command (e.g., enriched data such as sensor data, location data, temperature data, etc.). However, in some examples, the EH-enabled device may lack the power to properly convey the response message, the data may exceed the number of bits allowed by the query command, the EH-enabled device may generate additional data or any combination thereof after sending the response message. In such examples, the EH-enabled device may be unable to indicate such information to the reader wireless device, which may limit the ability of the EH-enabled device to fully convey data to the reader wireless device.

[0084] To support the synchronization of the status of an EH-enabled device or data generated by such a device between an EH-enabled device and a reader wireless device, the EH-enabled device may include an information indicator with a response message to the reader wireless device. In some cases, the information indicator may indicate the transmission status of data. For example, the information indicator may indicate the number of segments associated with the data based on the data size and the number of bits granted in the query command (e.g., for data of size N bits and a query command granting M bits, the EH-enabled device may indicate the number of segments associated with the data). (Segment). In such cases, the reader wireless device may send (e.g., specific to EH-capable devices) one or more subsequent query commands, thereby granting transmission resources for the corresponding segment to be used by the EH-capable device to transmit data via one or more subsequent response messages. Additionally or alternatively, the information indicator may indicate a trigger for sending the information indicator to an EH-capable device, information associated with the data (e.g., the type or size of the data), a request for transmission resources to communicate the data, or any combination thereof.

[0085] Figure 2 An example of a wireless communication system 200 indicating supporting environment IoT tag information according to one or more aspects of this disclosure is shown. The wireless communication system 200 may implement, or be implemented by, one or more aspects of the wireless communication system 100. For example, the wireless communication system 200 may include a reader wireless device 205, which may be a reference... Figure 1 Examples of network entity 105 or UE 115 described. Additionally, the wireless communication system 200 may include an EH-enabled device 210, which may be a reference device. Figure 1An example of the described UE 115. In some cases, the wireless communication system 200 may support multi-round data communication between the reader wireless device 205 and the EH-capable device 210 via a backscatter link. For example, as part of multiple tag access procedures between the reader wireless device 205 and the EH-capable device 210, the reader wireless device 205 may send one or more query commands 215 to the EH-capable device 210, and the EH-capable device 210 may send one or more response messages 220 (e.g., tag response messages) in response to the corresponding query command 215.

[0086] As described herein, the EH-capable device 210 can be an example of an environmental IoT device (e.g., a passive device without active RF components). Thus, the EH-capable device 210 can perform wireless communication with a reader wireless device 205 using backscattering techniques, which may include modulating event signals from the reader wireless device 205, such as a query command 215. To facilitate such backscattering communication, the EH-capable device 210 may include an antenna 240, an energy harvesting component 245, and a set of one or more impedances 250. The EH-capable device 210 can tune the reflection coefficient of the antenna 240 by switching on the set of one or more impedances 250, which can cause the EH-capable device 210 to reflect a variable amount of power from the event signal. For example, when using BPSK modulation, the EH-capable device 210 can switch between a first impedance 250 (e.g., Z1 or a relatively high impedance) and a second impedance 250 (e.g., Z...). N The load impedance of antenna 240 can be switched between (or a relatively matched load). Thus, device 210 with EH capability can reflect all the power of the event signal back to reader wireless device 205, or can collect the power of the event signal (e.g., using energy harvesting component 245) to indicate a binary value (e.g., 0, 1, or a combination thereof) back to reader wireless device 205.

[0087] In some examples, reader wireless device 205 may send a query command 215 (e.g., an initial group query) to a group of devices including device 210 with EH capability (e.g., via broadcast, groupcast, or unicast). The query command 215 may request device 210 with EH capability to respond to reader wireless device 205 using data generated by device 210 with EH capability (e.g., enriched data such as sensor data, location data, temperature data, etc.). In response to query command 215, device 210 with EH capability may send a response message 220, which may include device ID 225 (e.g., an identifier of device 210 with EH capability), data segment 230 (e.g., at least a portion of the data generated by device 210 with EH capability, data packets), information indicator 235, or any combination thereof.

[0088] In some cases, the EH-enabled device 210 may send the response message 220 in one or more data packets. For example, the EH-enabled device 210 may send the response message 220 as a first data packet including device ID 225 and data segment 230, and a second data packet including an information indicator 235 (e.g., separate from the first data packet). Alternatively, the EH-enabled device 210 may send the response message 220 as a single data packet including device ID 225, data segment 230, and information indicator 235 (e.g., information indicator 235 piggybacked on device ID 225 and data segment 230). Alternatively, the EH-enabled device 210 may send the response message 220 as a data packet including device ID 225 and data segment 230, and may include the information indicator 235 in a header or subheader associated with the data packet (e.g., if the information indicator 235 uses a relatively small number of bits).

[0089] Information indicator 235 may indicate the transmission status of data generated by EH-capable device 210, the status of EH-capable device 210, or both. In a non-limiting example, the information included in information indicator 235 may be codewords (with a specific size) that can be decrypted or interpreted by referring to a predetermined table configured to include a list of different possible codewords mapped to their associated representations or indications. Prior to deployment, this predetermined table may be pre-configured (e.g., pre-loaded) in both reader wireless device 205 and EH-capable device 210. As an example, information indicator 235 may be triggered by EH-capable device 210 for transmission to reader wireless device 205. Triggering of transmission information indicator 235 may be due to the energy level at EH-capable device 210 failing to meet an energy threshold (e.g., EH-capable device 210 lacks the energy or resources to transmit data), the data size exceeding a size threshold (e.g., the data is too large to be transmitted during a tag access process), or both. Additionally or alternatively, the trigger may be due to the EH-capable device 210 expecting to generate additional data after sending the corresponding response message 220, the EH-capable device 210 identifying (e.g., sending with the corresponding response message 220) data segment 230 as the last segment of data generated by the EH-capable device 210, the EH-capable device 210 determining whether new data is available for transmission (e.g., no new sensor measurement has been identified since the previous query command 215), the EH-capable device 210 identifying auxiliary information for the EH-capable device 210 (e.g., the amount of time, duration, or time interval for the EH-capable device 210 to collect energy between consecutive response messages 220), or any combination thereof. In some examples, the trigger for the transmission information indicator 235 may be an indication that no new data is available (e.g., for a sensor, if a new measurement has not been prepared since the last read). The information indicator 235 may be part of a tag response message or a tag information indicator (e.g., in the absence of a tag response message). In some cases, the information indicator 235 may be included as part of the tag response message, or as a separate part of the tag access, or as tag access header / subheader information.

[0090] For example, information indicator 235 may indicate the reason for tagging (e.g., lack of energy / resources, expectation of more enriched data, etc.). In some examples, information indicator 235 may indicate one or more parameters of subsequent enriched data (e.g., upcoming measurements that the EH-capable device 210 has not yet performed). For example, information indicator 235 may indicate the type of subsequent enriched data (e.g., sensed data, location data, temperature data, etc.), the size of the subsequent enriched data, or both, which may enable the EH-capable device 210 to transmit subsequent enriched data after completing one or more measurements (e.g., in a subsequent response message 220). Additionally or alternatively, information indicator 235 may indicate a request for transmission resources (e.g., expected backscatter link resources) for the EH-capable device 210 to transmit subsequent enriched data. In such examples, if information indicator 235 requests resources for a large amount of enriched data, reader wireless device 205 may grant relatively large transmission resources to the EH-capable device 210 to transmit the enriched data via query command 215.

[0091] For example, information indicator 235 may indicate the number of data segments 230 associated with data generated by device 210 with EH capability, as referenced below. Figure 3 Further description. In some examples, the EH-capable device 210 may use information indicator 235 to indicate the remaining number of data segments 230 in each successive response message 220. Alternatively, the EH-capable device 210 may use information indicator 235 to indicate the total number of data segments 230 only in the first (e.g., initial) response message 220.

[0092] In some cases, reader wireless device 205 may send one or more follow-up query commands 215 to device 210 with EH capability based on receive information indicator 235. For example, after receiving a response message 220 in response to group query command 215 from device 210 with EH capability, reader wireless device may send follow-up query command 215 specific to device 210 with EH capability. In some cases, reader wireless device 205 may modify or adjust one or more transmission parameters for follow-up query command 215 based on information indicator 235 included in response message 220. For example, if information indicator 235 indicates that a relatively large number of data segments 230 are available for transmission by device 210 with EH capability, reader wireless device 205 may adjust network switching (e.g., adjust the number of expected transmissions or data segments) to improve the power supply to device 210 with EH capability, increase the power supplied to device 210 with EH capability (e.g., when reader wireless device 205 provides a continuous waveform for backscattering to device 210 with EH capability, for example, if the number of expected transmissions or segments based on information indicator 235 is high), or both, to support communication of data segments 230.

[0093] For example, reader wireless device 205 can modify or adjust subsequent query commands 215 based on one or more prior information indicators 235 (e.g., the information history of EH-capable device 210) provided by EH-capable device 210. For instance, reader wireless device 205 can identify a threshold number of prior information indicators 235 sent by EH-capable device 210 indicating multiple data segments 230 to be sent by EH-capable device 210, and can configure one or more subsequent query commands 215 to grant EH-capable device 210 greater transmission resources (e.g., to support sending multiple data segments 230 with fewer tag access procedures). Also, reader wireless device 205 can identify a threshold number of prior information indicators 235 sent by EH-capable device 210 indicating that EH-capable device 210 has not yet generated new data, and can adjust the periodic reading interval for accessing EH-capable device 210 (e.g., transmitting query commands 215 less frequently). Additionally or alternatively, if the reader wireless device 205 receives from the EH-capable device 210 an information indicator 235 indicating that the corresponding data segment 230 (e.g., included in a response message 220 containing data segment 230) is the last data segment 230 or an information indicator 235 indicating that the EH-capable device 210 has not yet generated new data, the reader wireless device 205 may avoid transmitting the subsequent query command 215.

[0094] By including the information indicator 235 in the response message 220, backscatter communication between the reader wireless device 205 and the EH-enabled device 210 can be improved due to dynamic indication of the status of the data generated by the EH-enabled device 210, the status of the EH-enabled device 210, or both.

[0095] Figure 3 An example of a process flow 300 indicating supporting environment IoT tag information according to one or more aspects of this disclosure is shown. Process flow 300 may implement one or more aspects of wireless communication systems 100 and 200, or be implemented by such one or more aspects. For example, process flow 300 may illustrate communication between a reader wireless device 305 and a device 310 with EH capability, which may be a reference. Figure 1 and Figure 2 Examples of corresponding devices described. In some cases, process flow 300 may support a multi-round tag access process for an EH-capable device 310 to send data to a reader wireless device 305 using backscatter communication technology. For example, the EH-capable device 310 may send one or more response messages to the reader wireless device 305, the one or more response messages including data segments and information indicators indicating the number of data segments generated by the EH-capable device 310 for transmission. Alternative examples of the following may be implemented, some of which may be performed in a different order than described or not performed at all. In some cases, the process may include additional features not mentioned below, or additional processes may be added.

[0096] At 315, the reader wireless device 305 may send a query command (e.g., a first query command) to a group of EH-capable devices, including EH-capable device 310. In some cases, the query command may request EH-capable device 310 to respond to the query command using data generated by EH-capable device 310 (e.g., enriched data measured by EH-capable device 310). In some cases, the query command may be an example of a group query command (e.g., for multiple EH-capable devices including EH-capable device 310) or it may be a dedicated query command (e.g., dedicated to EH-capable device 310).

[0097] At 320, the EH-capable device 310 may send a response message (e.g., a first response message) to the reader wireless device 305 in response to a query command. This response message may include an identifier of the EH-capable device 310, a data packet including at least a portion of the data generated by the EH-capable device 310, and an information indicator associated with the EH-capable device 310 indicating the transmission status of the data. As described herein, the information indicator may include indications to: a trigger for sending the information indicator, the energy state of the EH-capable device 310, the type of data, the size of the data, a request for transmission resources for transmitting the data, or any combination thereof.

[0098] Additionally or alternatively, the information indicator may indicate the number of at least two data segments. For example, a response message may include a first data segment of at least two segments and an information indicator indicating the remaining number of at least two segments (or an indication of the total remaining bits). Alternatively, the information indicator may indicate the total number of at least two segments (e.g., indicating the remaining number of segments only in the initial response message). In some cases, the device 310 with EH capability may determine the number of the at least two segments based on the size of the data and the number of bits granted by the query command. For example, the query command may grant the device 310 with EH capability a transmission resource (e.g., a continuous wave for backscattering by the device 310 with EH capability) with the number of bits available for the device 310 to send a response message. Thus, if the device 310 with EH capability has generated more data than the number of bits available for transmission, the device 310 with EH capability may calculate the number of data segments based on the size of the transmission resource (e.g., dividing the data size by the number of bits in the transmission resource).

[0099] At 325, the reader wireless device 305 may modify one or more transmission parameters for subsequent query commands based on an information indicator provided by the EH-capable device 310. For example, in response to an information indicator indicating multiple data segments, the reader wireless device 305 may increase the size of subsequent transmission resources granted to the EH-capable device 310.

[0100] At 330, the reader wireless device 305 may send a second query command to the EH-capable device 310 based on receiving a response message from the EH-capable device 310. In some cases, the second query command may be specific to the EH-capable device 310 (e.g., a non-group query) and may be modified according to an information indicator provided by the EH-capable device 310 at 325 (i.e., the second query command is configured and sent using one or more modified transmission parameters). For example, the second query command may grant the EH-capable device 310 a second transmission resource for transmitting a second segment of the at least two data segments, and the second transmission resource may be greater than the transmission resource granted by the first query (e.g., because the EH-capable device 310 transmits multiple data segments).

[0101] At 335, the EH-enabled device 310 may, in response to receiving a second query command, send a second response message to the reader wireless device within a second transmission resource (e.g., during a period). In some cases, the second response message may include a second data segment and a second information indicator that may include the data. For example, the second information indicator may indicate the remaining number of data segments after sending the second data segment (e.g., if the EH-enabled device 310 indicates the remaining number of data segments in each response message). In some examples, the remaining number of data segments may vary between consecutive response messages due to the EH-enabled device 310 generating additional data, a change in the size of the transmission resource granted (e.g., an increase), or both. For example, if the EH-enabled device 310 generates additional data between response message transmissions (e.g., due to the arrival of new measurement data), the number of data segments may be increased compared to a previous response message, or if the reader wireless device 305 increases the size of the granted transmission resource, the number of data segments may be decreased compared to a previous response message.

[0102] At 340, reader wireless device 305 and EH-enabled device 310 can perform one or more subsequent tag access procedures (e.g., communication of query commands and corresponding response messages). For example, reader wireless device 305 can continue to grant transmission resources to EH-enabled device 310 based on the number of at least two data segments indicated by EH-enabled device 310.

[0103] In some cases, if the EH-enabled device 310 indicates the remaining number of data segments in each response message, the reader wireless device 305 can update the expected number of query commands after receiving each response message. As an example, a first query command may grant the EH-enabled device 310 500 bits of transmission resources. If the EH-enabled device 310 generates 1200 bits of data, it may transmit 500 bits of data within the transmission resources in the response message and may indicate the remaining number of two data segments via an information indicator (e.g., expecting to use two additional 500-bit resources to transmit the remaining 700 bits). In some cases, the reader wireless device 305 may send a second query command that grants the EH-enabled device 310 a second transmission resource of 600 bits (e.g., increased due to the EH-enabled device 310 generating multiple data segments). The EH-capable device 310 can transmit 600 bits of data in a second response message within a second transmission resource, and can indicate the remaining amount of a data segment (e.g., for transmitting the last 100 bits of data) via an information indicator. The reader wireless device 305 can send a third query command that grants the EH-capable device 310 a third transmission resource of 500 bits (e.g., reduced due to a smaller grant size satisfying the last segment). In some cases, the EH-capable device 310 can generate additional data after transmitting the second response message, and can indicate the increased number of data segments in the third response message. For example, the EH-capable device 310 can identify 2000 bits of data for transmission, transmit 500 bits of data in a third response message within a third transmission resource, and can indicate the total number of four data segments via an information indicator (e.g., calculated based on a current grant size of 500 bits and three remaining data segments). Reader wireless device 305 and device 310 with EH capability can continue to perform such communication until device 310 with EH capability has successfully delivered all data segments in the data segment (e.g., until the information indicator indicates the last data packet).

[0104] In some other cases, if the EH-enabled device 310 only indicates the number of data segments in the initial response message, the reader wireless device 305 may expect to send a number of query commands corresponding to the number of data segments. As an illustrative example, the first query command may grant the EH-enabled device 310 500 bits of transmission resources. If the EH-enabled device 310 generates 1200 bits of data, it may send 500 bits of data in the response message within the transmission resources and may indicate the number of two data segments via an information indicator (e.g., expecting to use two additional 500-bit resources to send the remaining 700 bits). In such examples, the reader wireless device 305 may expect to send two additional query commands to the EH-enabled device 310. For example, an EH-enabled device 310 may transmit a 500-bit data segment within a second transmission resource granted by the reader wireless device 305, and a 200-bit data segment within a third transmission resource granted by the reader wireless device 305 (e.g., with optional padding bits used to fill the grant). In such a scenario, if the EH-enabled device 310 generates additional data between consecutive response messages, the reader wireless device 305 and the EH-enabled device 310 may initiate another series of tag access procedures to convey the additional data (e.g., because the reader wireless device 305 is unaware of the additional data).

[0105] At 345, the EH-enabled device 310 may send a final response message to the reader wireless device 305. For example, this final response message may include a data segment and an information indicator (e.g., a last packet indication) identifying the data segment as the last of at least two segments. In some examples, the reader wireless device 305 may avoid transmitting subsequent query commands based on receiving the information indicator. For example, the reader wireless device 305 may continue to grant permission to the EH-enabled device 310 to transmit data segments until it receives an information indicator indicating the last data segment (e.g., the number of data segments is auxiliary information for the reader wireless device).

[0106] At 350, the reader wireless device 305 can perform tag information reassembly on data segments received from the EH-capable device 310. For example, the reader wireless device 305 can aggregate multiple data segments received from the EH-capable device 310 into a single message, which includes enriched data measured by the EH-capable device 310.

[0107] Figure 4An example of a process flow 400 indicating supporting environment IoT tag information according to one or more aspects of this disclosure is shown. Process flow 400 may implement, or be implemented by, one or more aspects of wireless communication systems 100 and 200 and process flow 300. For example, process flow 400 may display signaling between reader wireless device 405 and device 410 with EH capability, which may be referenced... Figures 1 to 3 Examples of corresponding devices described. In some cases, process flow 400 may support an EH-enabled device 410 sending an information indicator with a response message to a reader wireless device 405 to notify the reader wireless device 405 of the transmission status of data generated by the EH-enabled device 410. Alternative examples of the following may be implemented, some of which may be performed in a different order than described or not performed at all. In some cases, the process may include additional features not mentioned below, or additional processes may be added.

[0108] At 415, the reader wireless device 405 may send a first query command to the EH-capable device 410, which requests the EH-capable device 410 to respond to the first query command. In some cases, the reader wireless device 405 may send the first query command as a group query command to a group of EH-capable devices including the EH-capable device 410, or it may send the first query command as a dedicated query command (e.g., dedicated to the EH-capable device 410).

[0109] At 420, the EH-enabled device 410 may send a response message to the reader wireless device 405 in response to a first query command. This response message may include an identifier of the EH-enabled device 410, a data packet including at least a portion of the data generated by the EH-enabled device 410 in response to the first query command for transmission to the reader wireless device 405, and an information indicator associated with the EH-enabled device 410. In some examples, the EH-enabled device 410 may send the response message as a first packet including the identifier of the EH-enabled device 410 and the data packet, and a second packet including the information indicator (e.g., separate from the first packet). Alternatively, the EH-enabled device 410 may send the response message as including the identifier of the EH-enabled device 410, the data packet, and the information indicator (e.g., piggybacked on the tag response). For example, a device 410 with EH capability may send a response message as a packet that includes the identifier of the device 410 with EH capability and a data packet, and may include an information indicator in the header or subheader associated with the data packet (e.g., if the information indicator uses a relatively small number of bits).

[0110] In some cases, the information indicator may indicate the data transmission status, the status of the EH-capable device 410, or both. For example, the EH-capable device 410 may be triggered to transmit information to the reader wireless device 405. Such triggering may be due to the energy level at the EH-capable device 410 failing to meet an energy threshold (e.g., the EH-capable device 410 lacks the energy or resources to transmit data), the data size exceeding a size threshold (e.g., the data is too large to be transmitted during a tag access process), or both. Additionally or alternatively, the triggering may be due to the EH-capable device 410 generating additional data after transmitting a response message, the EH-capable device 410 identifying a portion of the data as the last segment of data generated by the EH-capable device 410, the EH-capable device 410 determining whether new data is available for transmission, the EH-capable device 410 identifying auxiliary information for the EH-capable device 410 (e.g., the time, duration, or interval at which the EH-capable device 410 collects energy), or any combination thereof.

[0111] Additionally or alternatively, the information indicator may indicate the number of at least two segments of data. For example, a device 410 with EH capability may identify that the number of bits granted by the first query command is less than the size of the data generated by the device 410 with EH capability. In some cases, the device 410 with EH capability may send at least two segments of data via multiple response messages (e.g., in some cases including an initial response message, and in some other cases not including an initial response message), wherein each of the multiple response messages may indicate the corresponding remaining number of the at least two segments. Alternatively, the device 410 with EH capability may indicate the number of the at least two segments only in a first (e.g., initial) response message (e.g., subsequent response messages may not include an indication of the remaining segments).

[0112] At 425, the reader wireless device 405 may modify one or more transmission parameters for sending the second query command based on a received information indicator. For example, the reader wireless device 405 may modify or adjust the network switching and power supply scheme for the EH-capable device 410, the transmission power of the second query command, the number of bits granted for the second query command, the periodic reading interval of the EH-capable device 410, or any combination thereof. For example, if the expected number of transmissions or segments increases or exceeds based on a received information indicator, the reader wireless device 405 may adjust the power supply scheme. In another example, if an EH-capable device 410 typically needs to transmit multiple segments due to insufficient resources, the reader wireless device 405 may increase the amount of resources (e.g., quantity, number) by the future granted size based on a request for more resources based on an information indicator. In another example, if an EH-capable device 410 (e.g., a sensor) typically indicates no new data via an information indicator, the reader wireless device 405 may reduce the periodic reading interval of that particular EH-capable device 410.

[0113] At 430, the reader wireless device 405 may send a second query command to the EH-capable device 410 based on the received information indicator. In some cases, based on the received information indicator at 425, the second query command may be specific to the EH-capable device 410 (i.e., configured and sent using one or more modified transmission parameters), and transmission resources (e.g., the number of bits associated with a continuous waveform backscattered by the EH-capable device 410) may be granted to the EH-capable device 410.

[0114] At 435, the EH-enabled device 410 may send a second response message to the reader wireless device 430 within the transmission resources granted by the second query command. For example, if the EH-enabled device 410 indicates at least two segments of data, the EH-enabled device 410 may send the first segment of the at least two segments in the second response message. In some cases, the second response message may include an information indicator that may include the remaining number of data segments, the data transmission status, the status of the EH-enabled device 410, or any combination thereof.

[0115] At 440, reader wireless device 405 may send a third query command to device 410 with EH capability based on receiving the second response message. In some cases, reader wireless device 405 may perform similar modifications to the one performed at 425 for subsequent query commands. In some cases, the third query command may include permission for the transmission of a second segment of at least two segments of data.

[0116] At 445, the EH-enabled device 410 may send a third response message to the reader wireless device 405 within the transmission resource granted by the third query command. In some cases, the EH-enabled device 410 may send the second segment of at least two data segments within the transmission resource. In some cases, the third response message may include an information indicator that indicates the second segment is the last segment of the at least two segments. For example, the EH-enabled device 410 may use the information indicator to notify the reader wireless device 405 that the data generated by the EH-enabled device 410 has been successfully delivered. It should be noted that any number of tag access procedures (e.g., query command and corresponding response message) may occur between the second and third response messages to facilitate communication of any number of data segments.

[0117] Figure 5 A block diagram 500 is shown of a device 505 indicated by supporting environment IoT tag information according to one or more aspects of this disclosure. Device 505 may be an example of various aspects of UE 115 as described herein. Device 505 may include a receiver 510, a transmitter 515, and a communication manager 520. Device 505, or one or more components of device 505 (e.g., receiver 510, transmitter 515, and communication manager 520), may include at least one processor that may be coupled to at least one memory to individually or jointly support or implement the described technologies. Each of these components may communicate with each other (e.g., via one or more buses).

[0118] Receiver 510 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 environmental IoT tag information indication). This information may be transmitted to other components of device 505. Receiver 510 may utilize a single antenna or a collection of multiple antennas.

[0119] Transmitter 515 may provide components for transmitting signals generated by other components of device 505. For example, transmitter 515 may transmit 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 environmental IoT tag information indication). In some examples, transmitter 515 may be co-located with receiver 510 in a transceiver module. Transmitter 515 may utilize a single antenna or a collection of multiple antennas.

[0120] The communication manager 520, receiver 510, transmitter 515, or various combinations thereof, or various components thereof, may be examples of components used to perform various aspects of environmental IoT tag information indication as described herein. For example, the communication manager 520, receiver 510, transmitter 515, or various combinations thereof, or components thereof, may be able to perform one or more of the functions described herein.

[0121] In some examples, the communication manager 520, receiver 510, transmitter 515, 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 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 device, 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).

[0122] Additionally or alternatively, the communication manager 520, receiver 510, transmitter 515, or various combinations or components thereof may be implemented in code executed by at least one processor (e.g., implemented as communication management software). If implemented in code executed by at least one processor, the functionality of the communication manager 520, receiver 510, transmitter 515, or various combinations or components thereof may be performed by a general-purpose processor, DSP, CPU, GPU, NPU, ASIC, FPGA, microcontroller, or any combination of these or other programmable logic devices (e.g., configured as or otherwise individually or jointly to support components for performing the functions described in this disclosure).

[0123] In some examples, the communication manager 520 may be configured to use or otherwise cooperate with the receiver 510, transmitter 515, or both to perform various operations (e.g., receiving, acquiring, monitoring, outputting, transmitting). For example, the communication manager 520 may receive information from the receiver 510, transmit information to the transmitter 515, or be integrated in combination with the receiver 510, transmitter 515, or both to acquire information, output information, or perform various other operations as described herein.

[0124] The communication manager 520 may support wireless communication according to examples disclosed herein. For example, the communication manager 520 may be capable of, configured to, or operable to support components for receiving a first query command from a reader wireless device, the first query command including a request for one or more EH-capable devices to respond to the first query command. The communication manager 520 may be capable of, configured to, or operable to support components for sending a first response message in response to receiving the first query command, the first response message including an identifier of the EH-capable device, a data packet, and an information indicator associated with the EH-capable device, the data packet including at least a portion of data generated by the EH-capable device in response to the first query command for transmission to the reader wireless device, the information indicator indicating the transmission status of the data. The communication manager 520 is capable of, configured to, or operable to support components for receiving a second query command from the reader wireless device based on the transmission of the first response message, the second query command including permission based on the transmission status of the data transmitted via the first response message, wherein the permission indicates one or more transmission resources provided by the reader wireless device.

[0125] By including or configuring a communication manager 520 according to an example as described herein, device 505 (e.g., at least one processor that controls or otherwise couples to receiver 510, transmitter 515, communication manager 520, or a combination thereof) can support techniques for improving environmental IoT tag access by including information indicators that indicate the data status of the tag, thereby enabling the tag to successfully communicate a relatively large amount of data.

[0126] Figure 6 A block diagram 600 is shown of a device 605 indicating a supporting environment IoT tag information according to one or more aspects of this disclosure. Device 605 may be an example of aspects of device 505 or UE 115 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, and communication manager 620), may include at least one processor that may be coupled to at least one memory to support the described technologies. Each of these components may communicate with each other (e.g., via one or more buses).

[0127] 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 environmental IoT tag information indication).

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.

[0234] As used herein, the word "or" in a list of items (e.g., a list of items accompanied by phrases such as "at least one of" or "one or more of") in the claims indicates an inclusive list, such that a list of at least one of, for example, A, B, or C means 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".

[0235] 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".

[0236] The term "determine" encompasses a variety of actions, and therefore, "determine" can include calculation, computation, processing, derivation, investigation, lookup (such as by searching in a table, database, or other data structure), identification, and similar actions. Furthermore, "determine" can include receiving (e.g., receiving information), accessing (e.g., accessing data stored in memory), etc. Moreover, "determine" can include parsing, acquiring, selecting, choosing, creating, and other similar actions.

[0237] 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 can be applied to any of the similar components having the same first reference numeral, regardless of the second reference numeral or other subsequent reference numerals.

[0238] 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 cases, known structures and devices are shown in block diagram form to avoid obscuring the concept of the described examples.

[0239] 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.
