[0054] In some wireless communications systems, one or more wireless devices may leverage (e.g., use or rely at least in part on) ambient radio waves to power one or more components of the wireless devices. For example, a wireless device may power one or more components of the wireless device by harvesting ambient energy from various radio waves received at the wireless device. Such a wireless device may use ambient energy harvesting instead of or in addition to a battery or a direct power source. In some systems, such a wireless device may be referred to or understood as an ambient device, such as an ambient internet of things (A-IoT) device. In some deployments, A-IoT devices may additionally support wireless backscattering to convey information to a reader device. Wireless backscattering may refer to a mechanism according to which an A-IoT device may receive a wireless signal and “backscatter” (e.g., transmit or reflect) the wireless signal with additional information. To convey information to a reader device via a backscattered signal, a backscattering A-IoT device may modulate or encode a received wireless signal such that the backscattered signal may be a modulated or encoded version of the received wireless signal. The component (s) of the A-IoT device that the A-IoT device uses for modulating or encoding the received wireless signal may be powered by energy harvested from ambient radio waves, the received wireless signal, or any combination thereof.
[0055] In some cases, A-IoT devices may use a continuous wave (CW) sinusoidal signal for one or both of ambient energy harvesting or wireless backscattering. For example, a wireless device may transmit a CW signal and an A-IoT device may use the CW signal to power one or more components of the A-IoT device or to perform wireless backscattering, or both. Such a wireless device that functions or operates as the CW emitter device may be positioned at various locations within a wireless network, including within or outside of a topology associated with a reader device or a controller of the reader device. In accordance with a CW emitter device being potentially outside of a topology associated with a reader device or a controller of the reader device, scenarios may arise in which a network entity is not aware of which devices within a network are (or could be) CW emitter devices. Without knowledge of which devices are (or could be) CW emitter devices, the network entity may be unable to control or coordinate interference or power control mechanisms, which may lead to relatively high interference conditions or relatively short battery lives, degrading overall system performance. Thus, some systems may benefit from additional mechanisms according to which a network entity is able to identify which devices within a system are or could function / operate as CW emitter devices.
[0056] Various aspects relate generally to CW emitter identification in A-IoT systems or deployments. Some aspects more specifically relate to one or more signaling mechanisms according to which a first wireless device may indicate, to a second wireless device, whether the first wireless device is a CW emitter device, with a CW emitter device being a device that is at least capable of transmitting (e.g., emitting) a CW signal. The first wireless device may indicate whether the first wireless device is a CW emitter device in one or more of various ways. In some aspects, the one or more signaling mechanisms that the first wireless device and the second wireless device use to communicate information indicative of whether the first wireless device is a CW emitter device may be associated with (e.g., depend on) a capability or mode of the first wireless device. For example, the first and second wireless devices may leverage one or more signaling mechanisms from a first set of signaling mechanisms in scenarios in which the first wireless device is associated with a first capability or mode and may leverage one or more signaling mechanisms from a second set of signaling mechanisms in scenarios in which the first wireless device is associated with a second capability or mode. In some examples, such a first capability or mode may be a “high-end” capability or mode and such a second capability or mode may be a “low-end” capability or mode.
[0057] In accordance with the first wireless device indicating whether the first wireless device is a CW emitter device (or, in other words, a “CW emitter” ) , the first wireless device and the second wireless device may selectively communicate (e.g., transmit or receive) control information associated with an emission of a CW signal from the first wireless device. For example, if the first wireless device is a CW emitter device, the second wireless device may transmit control information associated with CW emissions to the first wireless device. Otherwise, if the first wireless device is not a CW emitter device, the second wireless device may refrain from transmitting control information associated with CW emissions to the first wireless device. In some aspects, the second wireless device may be a network entity (e.g., a gNB or a base station, among other example network entities) or any other device associated with controlling at least CW emissions within a network including the first wireless device.
[0058] Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, by enabling or facilitating identification of CW emitter devices within a network, CW emissions throughout the network may be coordinated or controlled to mitigate (or avoid) high interference conditions and to extend an operational lifetime (e.g., a battery life) of the CW emitter devices. For example, in accordance with obtaining information indicative of which devices are or function / operate as CW emitter devices, a network entity may schedule CW emitters to operate at one or more specific times or at one or more specific power levels, or to transmit CW signals via one or more specific time-frequency resources, to achieve a target wireless backscattering performance, mitigate interference, or avoid an excess operational burden at the CW emitters. Further, by achieving such benefits, relatively more wireless communication systems may be able to deploy A-IoT devices with supporting CW emitter devices, which may enable such systems to utilize low-maintenance, low-complexity, low-cost, and low-power (e.g., self-powered) devices to support various applications and deployment scenarios.
[0059] Aspects of the disclosure are initially described in the context of wireless communications systems. Additionally, aspects of the disclosure are further illustrated by and described with reference to network topologies, a signaling diagram, and process flows. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to A-IoT CW emitter identification.
[0060] FIG. 1 shows an example of a wireless communications system 100 that supports A-IoT CW emitter identification in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more devices, such as one or more network devices (e.g., 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.
[0061] 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 communication link (s) 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 the communication link (s) 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) .
[0062] 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 in the wireless communications system 100 (e.g., other wireless communication devices, including UEs 115 or network entities 105) , as shown in FIG. 1.
[0063] 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.
[0064] In some examples, network entities 105 may communicate with a core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via backhaul communication link (s) 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 backhaul communication link (s) 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 the 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 link (s) 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) or 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.
[0065] One or more of the network entities 105 or network equipment 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 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 one network entity (e.g., a network entity 105 or a single RAN node, such as a base station 140) .
[0066] 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 multiple network entities (e.g., network entities 105) , such as an integrated access and 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) , such as a CU 160, a distributed unit (DU) , such as a DU 165, a radio unit (RU) , such as an RU 170, a RAN Intelligent Controller (RIC) , such as an RIC 175 (e.g., a Near-Real Time RIC (Near-RT RIC) , a Non-Real Time RIC (Non-RT RIC) ) , a Service Management and Orchestration (SMO) system, such as an SMO system 180, 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 of the 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) ) .
[0067] 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, or 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 adaptation protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 (e.g., one or more CUs) may be connected to a DU 165 (e.g., one or more DUs) or an RU 170 (e.g., one or more RUs) , or some combination thereof, and the DUs 165, RUs 170, or both may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by 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 multiple different RUs, such as an RU 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 a DU 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to an RU 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 (e.g., one or more of the network entities 105) that are in communication via such communication links.
[0068] In some wireless communications systems (e.g., the 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 of the network entities 105 (e.g., network entities 105 or IAB node (s) 104) may be partially controlled by each other. The IAB node (s) 104 may be referred to as a donor entity or an IAB donor. A DU 165 or an RU 170 may be partially controlled by a CU 160 associated with a network entity 105 or base station 140 (such as a donor network entity or a donor base station) . The one or more donor entities (e.g., IAB donors) may be in communication with one or more additional devices (e.g., IAB node (s) 104) via supported access and backhaul links (e.g., backhaul communication link (s) 120) . IAB node (s) 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DUs 165) of a coupled IAB donor. An IAB-MT may be equipped with 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 IAB node (s) 104 used for access via the DU 165 of the IAB node (s) 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB node (s) 104 may include one or more DUs (e.g., DUs 165) that support communication links with additional entities (e.g., IAB node (s) 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., the IAB node (s) 104 or components of the IAB node (s) 104) may be configured to operate according to the techniques described herein.
[0069] 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 test 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., components such as an IAB node, a DU 165, a CU 160, an RU 170, an RIC 175, an SMO system 180) .
[0070] 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, vehicles, or meters, among other examples.
[0071] The UEs 115 described herein may be able to communicate with various types of devices, such as UEs 115 that may sometimes operate 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.
[0072] The UEs 115 and the network entities 105 may wirelessly communicate with one another via the communication link (s) 125 (e.g., one or more access links) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined PHY layer structure for supporting the communication link (s) 125. For example, a carrier used for the communication link (s) 125 may include a portion of an RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information) , control signaling 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, such as one or more of the network entities 105) .
[0073] 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.
[0074] 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) .
[0075] 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, such as the wireless communications system 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.
[0076] 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) ) .
[0077] 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 UEs 115 (e.g., one or more UEs) or may include UE-specific search space sets for sending control information to a UE 115 (e.g., a specific UE) .
[0078] 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, such as the coverage area 110. In some examples, coverage areas 110 (e.g., different coverage areas) associated with different technologies may overlap, but the coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., a network entity 105) . In some other examples, overlapping coverage areas, such as a coverage area 110, associated with different technologies may be supported by different network entities (e.g., the network entities 105) . The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 support communications for coverage areas 110 (e.g., different coverage areas) using the same or different RATs.
[0079] 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.
[0080] In some examples, a UE 115 may be configured to support communicating directly with other UEs (e.g., one or more of the UEs 115) via a device-to-device (D2D) communication link, such as a 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 one or more of the 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.
[0081] 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.
[0082] 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 one hundred 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.
[0083] 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) RAT, 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.
[0084] 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.
[0085] 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) .
[0086] Some UEs 115, such as MTC or IoT devices, may be relatively 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.
[0087] In some wireless communication systems, such as the wireless communications system 100, one or more wireless devices may support A-IoT technologies. As described herein, a wireless device may be any device capable of transmitting or receiving wireless signaling, in addition to or as an alternative from transmitting or receiving wired signaling. A-IoT technologies may include or be associated with one or both of signal backscattering and ambient energy harvesting. A wireless device may perform or facilitate signal backscattering by reflecting or retransmitting a signal via one or more antennas or panels of the wireless device. Such a wireless device may reflect or retransmit a CW signal and, in some cases, may add, embed, encode, or modulate additional information into the reflected or retransmitted CW signal. Additionally, or alternatively, a wireless device may leverage or use ambient energy harvesting to power or charge one or more components of the wireless device by harvesting energy from ambient radio waves. Such a wireless device may harvest energy from ambient radio waves in accordance with receiving the ambient radio waves via one or more antennas or panels of the wireless device.
[0088] A-IoT devices may have or support one or more components or functionalities depending on a device type. In some examples, an A-IoT device may include a passive radio. Such an A-IoT device may support backscatter communication, may have zero or a relatively small amount of energy storage, may use RF signaling as an energy source, and may not perform transmit signal amplification. In some other examples, an A-IoT device may include an energy harvesting component, an energy storage component, and a low complexity semi-passive radio. Such an A-IoT device may support backscatter communication, may have a relatively small amount of energy storage, may use RF signaling as an energy source, and may sometimes perform transmit signal amplification. In some other examples, an A-IoT device may include an energy harvesting component, an energy storage component, and a low complexity active radio. Such an A-IoT device may support one or both of backscatter communication or active transmission and reception, may have a relatively medium amount of energy storage, may use RF signaling or solar radiation as an energy source, and may perform transmit signal amplification.
[0089] In some aspects, various wireless devices (e.g., one or more network entities 105 or UEs 115, or any combination thereof) , may support one or more signaling mechanisms according to which a device is able to indicate whether the device is or functions / operates as a CW emitter device. The device may indicate whether the device is or functions / operates as a CW emitter device via one or more explicit indications or via one or more implicit indications, or any combination thereof. Further, the device may indicate support or capability for CW emission via one or more of various types of signaling, including RRC signaling or A-IoT signaling, among other examples.
[0090] FIG. 2 shows example network topologies 200 and 201 that support A-IoT CW emitter identification in accordance with one or more aspects of the present disclosure. The network topologies 200 and 201 may implement or be implemented to realize one or more aspects of the wireless communications system 100. For example, the network topologies 200 and 201 illustrate wireless communications (e.g., wireless signaling) between various wireless communication devices, including devices as illustrated by and described with reference to FIG. 1. The network topologies 200 and 201 may be examples of A-IoT topologies, which may differ from RFID reader + tag topologies (with an RFID tag being associated with a simple structure, an envelope detector, and a carrier wave reflected / backscattered from a reader device) .
[0091] In accordance with the network topology 200, a network entity 105 may communicate with an A-IoT device 205 (e.g., a tag, such as an A-IoT tag) via a downlink 210 and an uplink 215. For example, the network topology 200 may be associated with a gNB –tag interface. In accordance with the network topology 201, a network entity 105 may communicate with a wireless device 220 (e.g., a UE 115) via a Uu link 225 and the wireless device 220 may communicate with an A-IoT device 205 (e.g., a tag, such as an A-IoT tag) via a forward link 230 and a backscatter link 235 (which may collectively be referred to as A-IoT links or channels) . For example, the network topology 201 may be associated with a gNB –UE –tag topology including a UE –tag interface (with the wireless device 220, such as the UE 115, operating as a reader device) . A Uu link may be associated with one or more of a physical downlink control channel (PDCCH) , a physical uplink control channel (PUCCH) , a physical downlink shared channel (PDSCH) , a physical uplink shared channel (PUSCH) , and an OFDM waveform. An A-IoT link or channel may be associated with a relatively simpler waveform and a relatively simpler format, such as one or more of a physical reader-to-device channel (PRDCH) or a physical device-to-reader channel (PDRCH) on-off keying (OOK) channel.
[0092] The forward link 230 and the backscatter link 235 may be different than sidelinks in accordance with communication via the backscatter link 235 being backscattered or reflected signaling (e.g., backscattered or reflected versions of the signaling sent via the forward link 230) . For example, signaling from an A-IoT device 205 may be understood as a transmission (e.g., an uplink transmission) that is backscattered on a carrier wave provided externally. In some scenarios, an A-IoT device 205 may lack support for RRC states, may lack mobility functions (e.g., at least no cell selection / re-selection -like function) , or may refrain from performing procedures associated with hybrid automatic repeat request (HARQ) or automatic repeat request (ARQ) . In some examples, an A-IoT device 205 may support energy harvesting and energy storage, in addition to backscatter communication.
[0093] FIG. 3 shows example network topologies 300, 301, 302, and 303 that support A-IoT CW emitter identification in accordance with one or more aspects of the present disclosure. The network topologies 300, 301, 302, and 303 may implement or be implemented to realize one or more aspects of the wireless communications system 100 or the network topologies 200 and 201. For example, each of the network topologies 300, 301, 302, and 303 illustrate communication between various wireless devices including one or more of a network entity 105, a UE 115, an A-IoT device 205, and a wireless device 305.
[0094] The network topologies 300 and 301 illustrate example topologies in which a CW emitter is inside of or within the topology (e.g., within a topology associated with a network entity 105) . In other words, in the network topologies 300 and 301, a network entity 105 or a UE 115 controlled by the network entity 105 may be a CW emitter (e.g., a device that performs a CW emission 320) . For example, in accordance with the network topology 300, a network entity 105 may perform a reader-to-device transmission 310 and a CW emission 320. In such examples, the CW emission 320 and a device-to-reader backscatter 315 may be located in one or more downlink resources or one or more uplink resources. For further example, in accordance with the network topology 301, a network entity 105 and a UE 115 may perform Uu communication 325 and the UE 115 may perform a reader-to-device transmission 310 and a CW emission 320. In such examples, the CW emission 320 and a device-to-reader backscatter 315 may be located in one or more uplink resources.
[0095] The network topologies 302 and 303 illustrate example topologies in which a CW emitter is outside of or external to the topology (e.g., outside of a topology associated with a network entity 105) . In other words, in the network topologies 302 and 303, a wireless device 305 may be or operate as the CW emitter device (e.g., the device that performs the CW emission 320) . For example, in accordance with the network topology 302, a network entity 105 may perform a reader-to-device transmission 310 and a wireless device 305 may perform a CW emission 320. In such examples, the CW emission 320 and a device-to-reader backscatter 315 may be frequency division duplexed in one or more uplink resources. For further example, in accordance with the network topology 303, a network entity 105 and a UE 115 may perform Uu communication 325, the UE 115 may perform a reader-to-device transmission 310, and a wireless device 305 may perform a CW emission 320. In such examples, the CW emission 320 and a device-to-reader backscatter 315 may be frequency division duplexed in one or more uplink resources or frequency division duplexed in one or more downlink resources.
[0096] In each of the network topologies 300, 301, 302, and 303, an A-IoT device 205 may receive a reader-to-device transmission 310 and a CW emission 320 and perform a device-to-reader backscatter 315 in association with (e.g., based on) receiving one or both of the reader-to-device transmission 310 and the CW emission 320. In some aspects, the A-IoT device 205 may use a CW (e.g., a CW emission 320) to perform the device-to-reader backscatter 315 (e.g., a device-to-reader transmission) . The A-IoT device 205 may use the CW emission 320 for one or both of backscattering and energy harvesting. In some aspects, the A-IoT device 205 may use energy harvested from the CW emission 320 to perform the device-to-reader backscatter 315, potentially among other energy sources (e.g., a battery or other RF signaling from devices within the system) . Additionally, or alternatively, the A-IoT device 205 may use energy harvested from the CW emission 320 to activate the A-IoT device 205 (e.g., to activate and power one or more components of the A-IoT device 205) and receive a reader-to-device transmission 310. In some aspects, additional CW emissions for RF energy harvesting (e.g., CW emissions in addition to a CW emission 320 for backscattering) may be used by the A-IoT device 205 for such an activation of the A-IoT device 205 and reception of the reader-to-device transmission 310.
[0097] In some scenarios, there may be a small frequency shift for a device-to-reader backscatter 315. In other words, the A-IoT device 205 may apply or cause a frequency shift when performing a device-to-reader backscatter 315. In such scenarios, a device may perform a CW emission 320 for backscattering in a same or similar spectrum as the device-to-reader backscatter 315. In some aspects, the CW emission 320 for backscattering may use a single-tone or a multi-tones waveform to facilitate interference cancellation, such as to facilitate relatively easier interference cancellation. Additionally, or alternatively, if the wireless device 305 uses a same antenna or panel for RF energy harvesting and reception of a reader-to-device transmission 310, a device may perform a CW emission 320 for energy harvesting in a same or similar spectrum as the reader-to-device transmission 310. In some aspects, a CW emission 320 for energy harvesting may use a same waveform as a reader-to-device transmission 310 for efficient power conversion.
[0098] Some networks may benefit from network control of one or more CW emitters, such that interference is controlled and such that sufficient RF energy is available at suitable times. In examples in which a CW emitter device is controlled by a network entity 105, the CW emitter device may be referred to or understood as a network controlled CW transmitter or energizer. Various scenarios may arise in which a network entity 105 is unable to identify or locate a CW emitter, as CW emitters may support varying levels of capability and may be present inside or outside of a topology associated with the network entity 105. Accordingly, in some implementations, one or more wireless devices may support or implement one or more configuration-or signaling-based mechanisms according to which a wireless device may convey information indicating whether the wireless device is or operates as a CW emitter.
[0099] Further, in some scenarios, a network entity 105 may control a CW emitter via wireless signaling, such as via an A-IoT channel or link. In scenarios in which the network entity 105 controls the CW emitter via an A-IoT channel or link, other A-IoT devices (which may be unintended receivers) may receive or “overhear” the control signaling, prompting those A-IoT devices to (unnecessarily) wake up and active one or more components. Accordingly, in some implementations, one or more wireless devices may support or implement one or more configuration-or signaling-based mechanisms according to which an A-IoT device is able to differentiate between control signaling associated with (e.g., intended for) a CW emitter and control signaling associated with (e.g., intended for) the A-IoT device.
[0100] Further, while the network topologies 300, 301, 302, and 303 are illustrated and described separately for purpose of example, the described techniques may be applicable to deployment scenarios involving any combination of aspects or devices from one or more of the network topologies 300, 301, 302, and 303. For example, the described techniques may be applicable to deployment scenarios involving two or more of a network entity 105, a UE 115, and a wireless device 305 performing CW emissions 320 or deployment scenarios involving two or more of a network entity 105, a UE 115, and a wireless device 305 performing reader-to-device transmissions 310, or any combination thereof. Further, a network controlled CW emitter may include a CW emitter that is controlled by a network entity 105 or by a UE 115, or both.
[0101] FIG. 4 shows an example signaling diagram 400 that supports A-IoT CW emitter identification in accordance with one or more aspects of the present disclosure. The signaling diagram 400 may implement or be implemented to realize one or more aspects of the wireless communications system 100, the network topologies 200 and 201, or the network topologies 300, 301, 302, and 303. For example, the signaling diagram 400 illustrates communication between a wireless device 405-a and a wireless device 405-b, each of which may be an example of any wireless device illustrated by and described with reference to FIGs. 1–3.
[0102] The wireless device 405-a or the wireless device 405-b may be a network entity 105, a UE 115, a wireless device 220, or a wireless device 305. In examples in which the wireless device 405-a is a UE 115, the wireless device 405-a may be an example of or otherwise referred to as an intermediate node, such as a full duplex UE 115. A full duplex UE 115 may be relatively more complex than a device that exclusively operates as a CW emitter, as a full duplex UE 115 may operate as a UE 115 and as a CW emitter (at the same time or at different times) . The wireless device 405-a and the wireless device 405-b may communicate via a communication link 410 (e.g., an uplink, a reverse link, or a backscatter link, among other examples) and a communication link 415 (e.g., a downlink or a forward link, among other examples) .
[0103] In some implementations, the wireless device 405-a may transmit, to the wireless device 405-b, a message 420 indicating whether the wireless device 405-a is a CW emitter device within a network of one or more devices (such as the A-IoT device 205) associated with ambient energy harvesting or wireless backscattering. For example, the wireless device 405-a may include or convey a CW emitter device indicator 425 within or via the message 420, the CW emitter device indicator 425 indicating whether the wireless device 405-a is a CW emitter. In other words, the wireless device 405-a may provide, indicate, or otherwise convey the CW emitter device indicator 425 within or via the message 420 in accordance with whether the wireless device 405-a performs or is capable of performing a CW emission 430 (which may be an example of a CW emission 320 as illustrated by and described with reference to FIG. 3) to facilitate energy harvesting or wireless backscattering at an A-IoT device 205 (or multiple A-IoT devices 205) .
[0104] The wireless device 405-a may transmit the message 420 via various types of signaling. In some examples, the wireless device 405-a may transmit the message 420 via a type of signaling in accordance with a capability or mode of the wireless device 405-a. For example, the wireless device 405-a may transmit the message 420 via a first type of signaling in accordance with the wireless device 405-a being a “high end” device or a device otherwise operating in a “high end” mode. Additional details relating to various examples of such a first type of signaling are illustrated by and described herein, including with reference to FIG. 5. For further example, the wireless device 405-a may transmit the message 420 via a second type of signaling in accordance with the wireless device 405-a being a “low end” device or a device otherwise operating in a “low end” mode. Additional details relating to various examples of such a second type of signaling are illustrated by and described herein, including with reference to FIG. 6.
[0105] In some implementations, the wireless device 405-a may additionally provide, indicate, or convey, via one or both of the message 420 or a message 435 (e.g., a second or separate message) , capability information 440 associated with the CW emission 430 by the wireless device 405-a. Generally, the CW emitter device indicator 425 may indicate whether the wireless device 405-a is a CW emitter and the capability information 440 (e.g., device ability or capability) may indicate radio-related ability or capability information. The wireless device 405-a may provide, indicate, or convey the capability information 440 in examples in which the wireless device 405-a is a CW emitter device (and is at least capable of performing the CW emission 430) . Otherwise, in examples in which the wireless device 405-a is not a CW emitter device (and does not capable of performing a CW emission 430) , the wireless device 405-a may refrain from transmitting the capability information 440.
[0106] The wireless device 405-a may transmit the message 420 and the message 435 via a same type of signaling or may transmit the message 420 and the message 435 via different types of signaling. For example, the wireless device 405-a may transmit both the message 420 and the message 435 via an A-IoT link or channel or may transmit the both the message 420 and the message 435 via a Uu link or channel. Additionally, or alternatively, the wireless device 405-a may transmit the message 420 via an A-IoT link or channel and may transmit the message 435 via a Uu link or channel (such as via RRC signaling) , or vice versa.
[0107] The capability information 440 may include any CW emitter related information. For example, the capability information 440 may include time domain capability information associated with the CW emission 430 by the wireless device 405-a. In such examples, the wireless device 405-a may indicate a switch delay among different bands or subcarriers for the CW emission 430. Additionally, or alternatively, the capability information 440 may include frequency domain capability information associated with the CW emission 430 by the wireless device 405-a. In such examples, the wireless device 405-a may indicate support for the CW emission 430 in one or both of an uplink band or a downlink band, support for one or both of single or multi-tones for the CW emission 430, or an upper limit quantity of multi-tones for the CW emission 430. The wireless device 405-a may indicate (as part of indicating support for multi-tones for the CW emission 430) support for one or both of a contiguous set of subcarriers / tones (e.g., subcarrier 1, subcarrier 2, subcarrier 3) or a discrete set of subcarriers / tones (e.g., subcarrier 1, subcarrier 4, subcarrier 7) .
[0108] Additionally, or alternatively, frequency domain capability information may include an indication of a waveform associated with the CW emission 430. For example, the wireless device 405-a may indicate support for OOK 1 or OOK 4 (e.g., Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing-OOK (DFT-S-OFDM-OOK) ) . In other words, more generally, the wireless device 405-a may indicate a type of OOK supported by the wireless device 405-a for the CW emission 430. Additionally, or alternatively, the wireless device 405-a may indicate whether the CW emission 430 by the wireless device 405-a is modulated or unmodulated and, if modulated, an overlayed sequence associated with the CW emission 430. The overlayed sequence may be an m-sequence, a Zadoff Chu sequence, a gold sequence, a random sequence, or a muti-sine sequence, among other examples. In some aspects, a muti-sine sequence may indicate that a phase for each subcarrier is the same or is increasing pi by each subcarrier.
[0109] Additionally, or alternatively, the capability information 440 may include power domain capability information associated with the CW emission 430 by the wireless device 405-a. In such examples, the wireless device 405-a may indicate one or both of an upper limit transmit power and a lower limit transmit power associated with the CW emission 430. In some examples, the wireless device 405-a may indicate the power domain capability information by indicating a capability of the wireless device 405-a to perform the CW emission 430 while satisfying one or more specific spectrum constraints at a specified or specific frequency band (e.g., as denoted by an NR band number) or at a specified or specific frequency (e.g., as denoted by an absolute radio frequency channel number (ARFCN) ) . For example, the wireless device 405-a may indicate a CW tone with a target transmit power Z decibel milliwatts (dBm) , with leakage / emission lower than X decibel (dB) with frequency separation from the CW tone ≥ Y kilohertz (kHz) at the specified or specific frequency band (e.g., as denoted by the NR band number) or at the specified or specific frequency (e.g., as denoted by the ARFCN) .
[0110] Additionally, or alternatively, the capability information 440 may include spatial domain capability information associated with the CW emission 430 by the wireless device 405-a. In such examples, the wireless device 405-a may indicate a geo-location of the wireless device 405-a. Additionally, or alternatively, the wireless device 405-a may indicate, via the capability information 440, whether the wireless device 405-a (which may, by default, transmit a CW without information contained) is able to exclusively operate as a CW-emitter or can additionally transmit / receive modulated (information carried) A-IoT signaling (e.g., as a reader or an intermediate UE 115) . Additionally, or alternatively, the wireless device 405-a may indicate, via the capability information 440, a duplexing capability of the wireless device 405-a (e.g., whether the wireless device 405-a supports full duplex or half duplex) .
[0111] Additionally, or alternatively, the wireless device 405-a may indicate, via the capability information 440, whether the wireless device 405-a is able to transmit / receive OFDM signals via a main radio of the wireless device 405-a (e.g., the wireless device 405-a may indicate a generation or a generational compatibility of the wireless device 405-a) . Additionally, or alternatively, the wireless device 405-a may indicate, via the capability information 440, whether the wireless device 405-a is able to simultaneously transmit NR uplink signaling and transmit a reader-to-device CW in the same or different frequency bands. Additionally, or alternatively, the wireless device 405-a may indicate, via the capability information 440, whether the wireless device 405-a is able to simultaneously receive NR downlink signaling and transmit a reader-to-device CW in the same or different frequency bands.
[0112] Additionally, or alternatively, the wireless device 405-a may indicate, via the capability information 440, whether the wireless device 405-a is a battery-driven equipment or an energy harvesting-based device. Additionally, or alternatively, the wireless device 405-a may indicate, via the capability information 440, whether the wireless device 405-a is able to perform the CW emission 430 for one or both of a backscatter link (e.g., for backscattering) or for energy harvesting. In such examples, the wireless device 405-a may indicate whether the wireless device 405-a supports different waveforms for energy harvesting and for wireless backscattering (as the wireless device 405-a may transmit different waveforms for energy harvesting and for a reader-to-device CW) .
[0113] The wireless device 405-b may selectively transmit, and the wireless device 405-a may selectively receive, control information 445 associated with an emission of a CW (e.g., a CW emission 430) from the wireless device 405-a in accordance with the message 420 indicating whether the wireless device 405-a is a CW emitter device (and in accordance with the capability information 440 of the wireless device 405-a) . For example, the wireless device 405-b may transmit the control information 445 to the wireless device 405-a in scenarios in which the wireless device 405-a is a CW emitter device. Alternatively, the wireless device 405-b may refrain from transmitting the control information 445 to the wireless device 405-a in scenarios in which the wireless device 405-a is not a CW emitter device. In examples in which the control information 445 is transmitted, the control information 445 may include information associated with (controlling) the CW emission 430 by the wireless device 405-a. For example, the control information 445 may include information indicative of one or more time windows within which the wireless device 405-a is to perform the CW emission 430, one or more time windows within which the wireless device 405-a is to refrain from performing the CW emission 430, one or more transmit powers to use for the CW emission 430, one or more frequency resources to use for the CW emission 430, one or more modulation sequences to use for the CW emission 430, one or more waveforms to use for the CW emission 430, or any combination thereof.
[0114] In some implementations, the wireless device 405-b may transmit the control information 445 in a manner to facilitate CW emitter message identification by one or more other devices (including, for example, the A-IoT device 205) . For example, the wireless device 405-b may transmit the control information 445 via an A-IoT link or channel (such that CW emitters may be controlled by the network via an A-IoT link or channel) and the wireless device 405-b may employ one or more mechanisms to facilitate an “early drop” of the control information 445 (or of a message or packet carrying the control information 445) by one or more unintended receivers of the control information 445. In other words, to avoid a false wake up of one or more A-IoT devices, the wireless device 405-b may support mechanisms according to which an A-IoT device is able to identify whether a message (from the network) is for an A-IoT CW emitter device or for another A-IoT device (e.g., a backscattering device or, generally, a non-CW emitter device) .
[0115] In some examples, to facilitate identification of different types of A-IoT messages (e.g., A-IoT (control) messages intended for CW emitters and A-IoT (control) messages intended for other A-IoT devices, such as backscattering devices or A-IoT tags) , the wireless device 405-b may use different preambles (or, generally, different start indicators or indicators present relatively early within a message) for the different types of A-IoT messages. For example, the wireless device 405-b may use a first set of one or more preambles for forward link CW emitter control messages and a second set of one or more preambles for other forward link A-IoT device messages. Additionally, or alternatively, to facilitate identification of different types of A-IoT messages, the wireless device 405-b may differentiate CW emitter control messages and other IoT device messages by L1 identifier (L1-ID) . For example, the wireless device 405-b may use a first set of one or more L1-IDs for CW emitter control messages and may use a second set of one or more L1-IDs for other A-IoT device messages. In some aspects, the wireless device 405-b may define a group ID for CW emitters or may define non-overlapping L1-ID code domains between A-IoT devices and CW emitters.
[0116] Additionally, or alternatively, to facilitate identification of different types of A-IoT messages, the wireless device 405-b may use different time-frequency resources for A-IoT device messages and CW emitter messages. In some of such examples, CW emitters may use a different A-IoT forward link subband as compared to other A-IoT devices. Additionally, or alternatively, the wireless device 405-b may transmit CW emitter control messages when A-IoT devices are configured, signaled, or indicated to be off (e.g., in examples in which duty-cycled monitoring is configured or indicated to A-IoT tags) . Additionally, or alternatively, the wireless device 405-b may configure or indicate different (e.g., separate) resource pools for CW emitters and other A-IoT devices. For example, CW emitters may use a dedicated resource pool configuration (as signaled or indicated by the wireless device 405-b) and the wireless device 405-b may transmit control messages intended for CW emitters via time-frequency resources of the dedicated resource pool.
[0117] FIG. 5 shows example process flows 500, 501, 502, and 503 that support A-IoT CW emitter identification in accordance with one or more aspects of the present disclosure. The process flows 500, 501, 502, and 503 may implement or be implemented to realize one or more aspects of the wireless communications system 100, the network topologies 200 and 201, the network topologies 300, 301, 302, and 303, or the signaling diagram 400.
[0118] The process flows 500, 501, 502, and 503 may illustrate communication between the wireless device 405-a and the wireless device 405-b in examples in which the wireless device 405-a is a “high end” device or in a “high end” mode, such as in examples in which the wireless device 405-a supports a (nearly) full NR protocol and functions such as NR random access channel (NR-RACH) or radio resource management, among other examples. In such examples, the wireless device 405-a may transmit a message indicating whether the wireless device 405-a is a CW emitter device via RRC signaling.
[0119] Alternative examples of the following may be implemented. Some steps are performed in a different order than described or are not performed at all. In some implementations, steps may include additional features not mentioned below, or further steps may be added. Further, although example devices are shown performing the operations of the process flows 500, 501, 502, and 503, some aspects of some operations also may be performed by one or more other wireless communication devices without exceeding the scope of the present disclosure. Further, while the process flows 500, 501, 502, and 503 are illustrated and described separately for purpose of example, the described techniques may be applicable to signaling mechanisms or sequences involving any combination of aspects from one or more of the process flows 500, 501, 502, and 503.
[0120] In accordance with the process flow 500, at 505, the wireless device 405-b may transmit a capability enquiry message to the wireless device 405-a. In some aspects, the capability enquiry message may be a UECapabilityEnquiry message. At 510, the wireless device 405-a may transmit a capability information message to the wireless device 405-b. The capability information message, which may be an example of the message 420 or the message 435, may be a UECapabilityInformation message. The wireless device 405-a may transmit the capability information message (e.g., the UECapabilityInformation message) via UE assistance information, such that UE assistance information may include CW emitter information. The wireless device 405-a may transmit the capability information message in association with (e.g., responsive to) receiving the capability enquiry message from the wireless device 405-b.
[0121] In accordance with the process flow 501, at 515, the wireless device 405-a and the wireless device 405-b may communicate (e.g., transmit or receive) one or more messages associated with an RRC reconfiguration at the wireless device 405-a. For example, the one or more messages may be associated with an RRCReconfiguration procedure between the wireless device 405-a and the wireless device 405-b. At 520, the wireless device 405-a may transmit an assistance information message to the wireless device 405-b. The assistance information message, which may be an example of the message 420 or the message 435, may be a UEAssistanceInformation message. In such examples, UE assistance information may include CW emitter information. The wireless device 405-a may transmit the assistance information message in association with (e.g., responsive to) communicating the one or more messages associated with the RRC reconfiguration with the wireless device 405-b.
[0122] In accordance with the process flow 502, at 525, the wireless device 405-a and the wireless device 405-b may communicate (e.g., transmit or receive) one or more random access messages. The random access messages may include a message 1 (msg1) , a message 2 (msg2) , a message 3 (msg3) , a message 4 (msg4) , or any combination thereof. Additionally, or alternatively, the random access messages may include a message A (msgA) , a message B (msgB) , or both. In some aspects, the random access messages may be associated with an establishment of an RRC connection between the wireless device 405-a and the wireless device 405-b. At 530, the wireless device 405-a may transmit a random access message to the wireless device 405-b. The random access message, which may be an example of the message 420 or the message 435, may be a message 5 (msg5) or a message C (msgC) . In such examples, random access signaling may include CW emitter information (e.g., NR RACH for CW emitters) . The wireless device 405-a may transmit the random access message in association with (e.g., responsive to) communicating the one or more random access messages with the wireless device 405-b.
[0123] In accordance with the process flow 503, at 535, the wireless device 405-b may transmit an uplink resource assignment to the wireless device 405-a. In some aspects, the wireless device 405-b may transmit the uplink resource assignment in association with an establishment of an RRC connection between the wireless device 405-a and the wireless device 405-b. At 540, the wireless device 405-a may transmit a setup complete message to the wireless device 405-b. The setup complete message, which may be an example of the message 420 or the message 435, may be an rrcSetupComplete message. The wireless device 405-a may transmit the setup complete message in association with (e.g., responsive to) receiving the uplink resource assignment (associated with the establishment of the RRC connection) from the wireless device 405-b.
[0124] FIG. 6 shows example process flows 600, 601, and 602 that support A-IoT CW emitter identification in accordance with one or more aspects of the present disclosure. The process flows 600, 601, and 602 may implement or be implemented to realize one or more aspects of the wireless communications system 100, the network topologies 200 and 201, the network topologies 300, 301, 302, and 303, or the signaling diagram 400.
[0125] The process flows 600, 601, and 602 may illustrate communication between the wireless device 405-a and the wireless device 405-b in examples in which the wireless device 405-a is a “low end” device or in a “low end” mode, such as in examples in which the wireless device 405-a supports a relatively simple protocol (e.g., an A-IoT protocol) . For example, the wireless device 405-a may be an active A-IoT device or another type of device operating in a low power mode, such as to extend a battery life or otherwise reduce power consumption at the wireless device 405-a. In such examples, the wireless device 405-a may transmit a message indicating whether the wireless device 405-a is a CW emitter device via an A-IoT link or channel (or via other signaling that is otherwise associated with an A-IoT protocol) .
[0126] Alternative examples of the following may be implemented. Some steps are performed in a different order than described or are not performed at all. In some implementations, steps may include additional features not mentioned below, or further steps may be added. Further, although example devices are shown performing the operations of the process flows 600, 601, and 602, some aspects of some operations also may be performed by one or more other wireless communication devices without exceeding the scope of the present disclosure. Further, while the process flows 600, 601, and 602 are illustrated and described separately for purpose of example, the described techniques may be applicable to signaling mechanisms or sequences involving any combination of aspects from one or more of the process flows 600, 601, and 602.
[0127] In accordance with the process flow 600, the wireless device 405-a and the wireless device 405-b may support CW emitter identification during or as part of a CW emitter random access procedure (e.g., during or within one or more steps of a four-step procedure) . At 605, the wireless device 405-b may transmit a trigger message. The trigger message may be associated with triggering or initiating the random access procedure between the wireless device 405-a and the wireless device 405-b. In some implementations, the trigger message may include information indicating that the wireless device 405-b is querying CW emitters (e.g., devices other than A-IoT devices, such as other than passive A-IoT devices) in coverage of the wireless device 405-b. In other words, the trigger message may exclusively query or trigger CW emitters to perform the random access procedure such that CW emitters may perform or participate in the random access procedure initiated by the trigger message and other devices (e.g., A-IoT devices) may refrain from performing or participating in the random access procedure initiated by the trigger message.
[0128] In some examples, the trigger message (e.g., a forward link trigger message) may include one or more bits or fields to indicate a device type queried by the trigger message. In such examples, the trigger message may explicitly indicate the device type (e.g., CW emitter or A-IoT device) queried by the trigger message. Additionally, or alternatively, the trigger message may implicitly indicate a device type queried by the trigger message. For example, the trigger message may include a preamble or delimiter that implicitly indicates the device type queried by the trigger message. In such examples, a first set of one or more preambles or delimiters may indicate that the trigger message queries CW emitters and a second set of one or more preambles or delimiters may indicate that the trigger message queries other devices (e.g., A-IoT devices) .
[0129] At 610, the wireless device 405-a may transmit an A-IoT msg1 to the wireless device 405-b in association with receiving the trigger message. In some implementations, the wireless device 405-a may transmit the A-IoT msg1 in accordance with the wireless device 405-a being associated with a device type queried by the trigger message. In such implementations, the A-IoT msg1 may (implicitly) indicate that the wireless device 405-a is a CW emitter in examples in which the trigger message queries CW emitters. Accordingly, the A-IoT msg1 may be an example of the message 420.
[0130] At 615, the wireless device 405-b may transmit an A-IoT msg2 to the wireless device 405-a in association with receiving the A-IoT msg1. At 620, the wireless device 405-a may transmit an A-IoT msg3 in association with receiving the A-IoT msg2. At 625, in some examples, the wireless device 405-b may transmit an A-IoT msg4 (e.g., an acknowledgment (ACK) ) .
[0131] In some implementations, one or both of the A-IoT msg1 and the A-IoT msg3 may indicate whether the wireless device 405-a is a CW emitter (such that one or both of the A-IoT msg1 and the A-IoT msg3 may be an example of the message 420) . In such implementations, the A-IoT msg1 or the A-IoT msg3 may indicate whether the wireless device 405-a is a CW emitter via an explicit indication or via an implicit indication. In some examples, the A-IoT msg1 or the A-IoT msg3 may indicate whether the wireless device 405-a is a CW emitter in accordance with a code domain indication. For example, a device hardware identifier of the wireless device 405-a may indicate whether the wireless device 405-a is a CW emitter and the A-IoT msg1 or the A-IoT msg3 may include or be associated with a sequence or indication corresponding to the device hardware identifier of the wireless device 405-a. Additionally, or alternatively, A-IoT msg1 or the A-IoT msg3 may indicate whether the wireless device 405-a is a CW emitter in accordance with time-frequency domain indication. For example, CW emitters may use different (backscatter link) time-frequency resources than other devices (e.g., non-CW emitters) . In such examples, the wireless device 405-a may transmit the A-IoT msg1 or the A-IoT msg3 via a specific time-frequency resource to indicate whether the wireless device 405-a is a CW emitter (with, for example, a first set of time-frequency resources corresponding to (being used by) CW emitters and a second set of time-frequency resources corresponding to (being used by) non-CW emitters) .
[0132] In accordance with the process flow 601, the wireless device 405-a and the wireless device 405-b also may support CW emitter identification during or as part of a CW emitter random access procedure (e.g., during or within one or more steps of a two-step procedure) . At 630, the wireless device 405-b may transmit a trigger message. The trigger message may be associated with triggering or initiating the random access procedure between the wireless device 405-a and the wireless device 405-b. In some implementations, the trigger message may include information indicating that the wireless device 405-b is querying CW emitters, as described with reference to the trigger message transmitted at 605.
[0133] At 635, the wireless device 405-a may transmit an A-IoT msgA in association with receiving the trigger message. In some implementations, the wireless device 405-a may transmit the A-IoT msgA in accordance with the wireless device 405-a being associated with a device type queried by the trigger message. In such implementations, the A-IoT msgA may (implicitly) indicate that the wireless device 405-a is a CW emitter in examples in which the trigger message queries CW emitters. In some implementations, the A-IoT msgA may indicate whether the wireless device 405-a is a CW emitter in accordance with a code domain indication or a time-frequency domain indication, as described with reference to the A-IoT msg1 transmitted at 610 and the A-IoT msg3 transmitted at 620. In either or both implementations, the A-IoT msgA may be an example of the message 420. At 640, in some examples, the wireless device 405-b may transmit an A-IoT msgB (e.g., an ACK) .
[0134] In accordance with the process flow 602, the wireless device 405-a and the wireless device 405-b also may support CW emitter identification after CW emitter random access. For example, at 645, the wireless device 405-a and the wireless device 405-b may communicate (e.g., transmit or receive) one or more A-IoT random access messages (e.g., one or more of A-IoT msg1 / 2 / 3 / 4 or one or more of A-IoT msgA / B) . At 650, in association with communicating the one or more A-IoT random access messages, the wireless device 405-b may transmit a trigger message. The trigger message may solicit from or query the wireless device 405-a for device capability information, including information indicative of whether the wireless device 405-a is a CW emitter. At 655, the wireless device 405-a may transmit capability information to indicate whether the wireless device 405-a is a CW emitter. In other words, the wireless device 405-a may transmit device capability information via an A-IoT (backscatter) link or channel to indicate whether the wireless device 405-a is a CW emitter. The wireless device 405-a may transmit the capability information via a message requested by the trigger message, with such a message requested by the trigger message being an example of the message 420 or the message 435.
