[0001] The following relates to wireless communications, including techniques for identifying and mitigating cross link interference (CLI) in internet of things (IoT) scenarios.BACKGROUND
[0002] Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power) . Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal FDMA (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) . A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE) .SUMMARY

[0057] Some wireless communications systems may support internet-of-things (IoT) devices in which the IoT device may receive carrier waves (CW) (e.g., to power the IoT device) , forward link (FL) data, or both, and may transmit (e.g., or reflect) backscatter link (BL) data. However, in some cases, the IoT device may experience cross link interference (CLI) due to uplink transmissions by one or more UEs. That is, the uplink transmissions performed by the one or more UEs may interfere with FL link data to be received by the IoT device. In such cases, the one or more UEs may be one or more UEs located within a threshold proximity to the IoT device, may be a UE communicating with the IoT device, or both. Further, the IoT device may not be capable of measuring or reporting the CLI, such that neither the IoT device nor a wireless device communicating with the IoT device may be capable of mitigating the CLI experienced by the IoT device.
[0058] Accordingly, techniques described herein may enable a network entity to determine one or more UEs causing CLI at the IoT device, which may be referred to as aggressor UEs, and reschedule the one or more aggressor UEs to mitigate the CLI. For example, the network entity may identify (e.g., detect) that an IoT device may be experiencing CLI (e.g., based on network implementation) . Thus, to identify one or more aggressor UEs causing the CLI, the network may transmit, to multiple UEs, a control message indicating one or more resources used by the IoT device to transmit BL, which may be referred to as BL resources. Each of the multiple UEs may measure the one or more BL resources to generate one or more channel quality metrics (e.g., may measure the one or more channel quality metrics via the one or more BL resources) and may transmit, to the network entity, a report indicative of the one or more channel quality metrics. Thus, the network entity may determine one or more aggressor UEs from the multiple UEs based on the report channel quality metrics and may reschedule the one or more aggressor UEs to mitigate the CLI.
[0059] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are then described in the context of tone allocations and a process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques for identifying and mitigating CLI in IoT scenarios.
[0060] FIG. 1 shows an example of a wireless communications system 100 that supports techniques for identifying and mitigating CLI in IoT scenarios 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] UEs 115 may be dispersed throughout the wireless communications system 100, and each UE 115 may be stationary or mobile. A UE 115 may also 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. A UE 115 may be a device such as a cellular phone, a smart phone, a personal digital assistant (PDA) , a multimedia / entertainment device (e.g., a radio, a MP3 player, or a video device) , a camera, a gaming device, a navigation / positioning device (e.g., GNSS (global navigation satellite system) devices based on, for example, GPS (global positioning system) , Beidou, GLONASS, or Galileo, or a terrestrial-based device) , a tablet computer, a laptop computer, a netbook, a smartbook, a personal computer, a smart device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, virtual reality goggles, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet) ) , a drone, a robot / robotic device, a vehicle, a vehicular device, a meter (e.g., parking meter, electric meter, gas meter, water meter) , a monitor, a gas pump, an appliance (e.g., kitchen appliance, washing machine, dryer) , a location tag, a medical / healthcare device, an implant, a sensor / actuator, a display, or any other suitable device configured to communicate via a wireless or wired medium. In some examples, a UE 115 may also refer to a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or an MTC device, or the like, which may be implemented in various articles such as appliances, drones, robots, vehicles, meters, or the like.
[0063] Some UEs 115, such as MTC or IoT devices, may be low cost or low complexity devices, and may provide for automated communication between machines (e.g., via Machine-to-Machine (M2M) communication) . M2M communication or MTC may refer to data communication technologies that allow devices to communicate with one another or a base station 105 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 that information to a central server or application program that can make use of the information or present the information to humans interacting with the program or application. Some UEs 115 may be designed to collect information or enable automated behavior of machines. 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. In an aspect, techniques disclosed herein may be applicable to MTC or IoT UEs. MTC or IoT UEs may include MTC / enhanced MTC (eMTC, also referred to as CAT-M, Cat M1) UEs, NB-IoT (also referred to as CAT NB1) UEs, as well as other types of UEs. eMTC and NB-IoT may refer to future technologies that may evolve from or may be based on these technologies. For example, eMTC may include FeMTC (further eMTC) , eFeMTC (enhanced further eMTC) , and mMTC (massive MTC) , and NB-IoT may include eNB-IoT (enhanced NB-IoT) , and FeNB-IoT (further enhanced NB-IoT) .
[0064] Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power) . A wireless network, for example a wireless local area network (WLAN) , such as a Wi-Fi (e.g., Institute of Electrical and Electronics Engineers (IEEE) 802.11) network may include an access point (AP) that may communicate with one or more wireless or mobile devices. The AP may be coupled to a network, such as the Internet, and may enable a mobile device to communicate via the network (or communicate with other devices coupled to the access point) . A wireless device may communicate with a network device bi-directionally. For example, in a WLAN, a device may communicate with an associated AP via downlink (e.g., the communication link from the AP to the device) and uplink (e.g., the communication link from the device to the AP) . A wireless personal area network (PAN) , which may include a Bluetooth connection, may provide for short range wireless connections between two or more paired wireless devices. For example, wireless devices such as cellular phones may utilize wireless PAN communications to exchange information such as audio signals with wireless headsets. Components within a wireless communication system may be coupled (for example, operatively, communicatively, functionally, electronically, and / or electrically) to each other.
[0065] 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.
[0066] 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.
[0067] 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) .
[0068] 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) ) .
[0069] 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.
[0070] 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.
[0071] 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) .
[0072] 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.
[0073] 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.
[0074] 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) .
[0075] 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.
[0076] 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) .
[0077] 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.
[0078] 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) ) .
[0079] 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) .
[0080] 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.
[0081] 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.
[0082] 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.
[0083] 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.
[0084] 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.
[0085] 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.
[0086] 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.
[0087] 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) .
[0088] In some cases, wireless devices of the wireless communications system 100, such as a UE 115, a network entity 105, or both, may support measurement of CLI. For example, a UE 115 may support Layer 3 CLI measurement to identify (e.g., characterize) interference (e.g., long-term interference) between nearby UEs 115 around a cell boundary (e.g., due to a semi-static nature of the CLI) . In some cases, the UE 115 may support one or more types of CLI measurments, such as sounding reference signal (SRS) reference signal received power (RSRP) , CLI reference signal strength indicator (RSSI) , or both. In such cases, to enable CLI measurement, the UE 115, which may be a victim UE 115 (e.g., experiencing the CLI) and the network entity 105 may perform a CLI mitigation procedure in which the network entity 105 may indicate to (e.g., configure) one or more CLI resources to the victim UE 115, the victim UE 115 may measure RSRP, RSSI, or both, associated with the CLI resources, and the victim UE 115 may report the measured RSRP, RSSI, or both, to the network entity 105. Thus, the network entity 105 may identify one or more aggressor UEs 115 causing the CLI at the victim UE 115 (e.g., a source of CLI) and may reschedule one or more resources associated with the one or more aggressor UEs 115 to reduce (e.g., degrade) or remove the CLI. For example, the network entity 105 may configure the victim UE 115 and the one or more aggressor UEs 115 in different resources (e.g., TDD, FDD, or the like thereof) . In such cases, the CLI mitigation procedure may be transparent to the one or more aggressor UE 115 due to the measurements being performed by the victim UE 115
[0089] Some wireless communications systems, such as the wireless communications system 100, may support IoT devices, in which the IoT device 205 may receive CW signals, FL signals, or both, from a network node, such as a UE 115 or a network entity 105, and may transmit (e.g., or reflect) BL signals to the network node. In some cases, to support IoT signaling (e.g., CW signals, FL signals, BL signals, or any combination thereof) , the network node may communicate Uu signaling via a first spectrum (e.g., Uu spectrum, NR spectrum) and may communicate IoT signaling via a second spectrum (e.g., separate spectrums for the IoT signaling and the Uu signaling to avoid impacts between the IoT signaling and the Uu signaling) . In some other cases, the network node (e.g., the UE 115) may communicate both CW signals / FL signals and uplink signals in a same spectrum (e.g., the first spectrum) , where the CW signals / FL signals may be allocated with one or more fixed tones (e.g., IoT tones) . In such cases, if both CW signals / FL signals and the uplink signals are transmitted from the network node (e.g., a same UE 115) , the CW signals / FL signals and the uplink signals may share a same transmit transceiver. However, in such cases, the uplink signals may cause CLI in reception of the CW signals / FL signals by the IoT device. In some other cases, the network node (e.g., the network entity 105) may communicate both CW signals / FL signals and downlink signals in a same spectrum (e.g., the first spectrum) . In such cases, the downlink signals may cause CLI in reception of the CW signals / FL signals by the IoT device. In some other cases, the CW signals / FL signals may be configured with a hopping pattern to achieve diversity gain, robust performance, or both. However, in such cases, the hopping may dynamically conflict with uplink signals (e.g., by the UE 115) or downlink signals (e.g., by the network entity 105) .
[0090] In some cases, the wireless communications system 100 may support techniques to enable a network entity 10 to determine one or more UEs 115 causing CLI at the IoT device, which may be referred to as aggressor UEs 115, and reschedule the one or more aggressor UEs 115 to mitigate the CLI. For example, the network entity 105 may identify (e.g., detect) that an IoT device may be experiencing CLI (e.g., based on network implementation) . Thus, to identify one or more aggressor UEs 115 causing the CLI, the network may transmit, to multiple UEs 115, a control message indicating one or more resources used by the IoT device to transmit BL, which may be referred to as BL resources. Each of the multiple UEs 115 may measure the one or more BL resources to generate one or more channel quality metrics (e.g., may generate the one or more channel quality metrics based on measuring the one or more BL resources) and may transmit, to the network entity 105, a report indicative of the one or more channel quality metrics. Thus, the network entity 105 may determine one or more aggressor UEs 115 from the multiple UEs 115 based on the report channel quality metrics and may reschedule the one or more aggressor UEs 115 to mitigate the CLI.
[0091] FIGs. 2A and 2B each show an example of a wireless communications system 200 (e.g., a wireless communications system 200 a and a wireless communications system 200 b) that supports techniques for identifying and mitigating CLI in IoT scenarios in accordance with one or more aspects of the present disclosure. In some cases, the wireless communications systems 200 may implement or be implemented by aspects of the wireless communications system 100. For example, the wireless communications systems 200 may include one or more UEs 115 (e.g., a UE 115-a, a UE 115-b, and a UE 115-c) and one or more network entities 105 (e.g., a network entity 105-a and a network entity 105-b) , which may be examples of the corresponding devices as described herein.
[0092] Some wireless communications systems, such as the wireless communications system 200-a and the wireless communications system 200-b, may support IoT devices 205, such as an IoT device 205-a and an IoT device 205-b, in which the IoT device 205 may receive CW 225 (e.g., CW signaling to power the IoT device 205) , FL 220 (e.g., FL data, FL signaling) , or both, from a network node (e.g., a UE 115 or a network entity 105) and may transmit (e.g., or reflect) BL 215 (e.g., BL data, BL signaling) to the network node. In some cases, the network node may transmit the CW 225 (e.g., backscattering CW 225) to enable the IoT device 205 to transmit the BL 215 and, in some other cases, the network node may transmit the CW 225 (e.g., energy-transfer CW 225) to provide energy to the IoT device 205. Additionally, or alternatively, one or more of the IoT devices 205 may be ambient IoT devices 205 that may be capable of operating using ambient energy (e.g., without a conventional power source) , such as radio waves (e.g., CW) , light, motion, heat, or the like thereof.
[0093] In some cases, an IoT device 205 may communicate with a single wireless device, such as a UE 115 or a network entity 105. For example, as depicted in FIG. 2A, the IoT device 205-a may transmit BL 215-ato the network entity 105-a and may receive FL 220-a, CW 225-a, or both, from the network entity 105-a. In such cases, the network entity 105-a may operate in a full duplex mode relative to the IoT device 205-a(e.g., the IoT device 205-a may both transmit signaling to and receive signaling from the network entity 105-a) . Similarly, as depicted in FIG. 2B, the IoT device 205-b may transmit BL 215-b to the UE 115-b and may receive FL 220-b, CW 225-b, or both, from the UE 115-b. In such cases, the UE 115-b may operate in a full duplex mode relative to the IoT device 205-b (e.g., the IoT device 205-b may both transmit signaling to and receive signaling from the UE 115-b) .
[0094] In some other cases, an IoT device 205 may communicate with multiple wireless devices, such as one or more UEs 115, one or more network entities 105, or both. In such cases, each wireless device of the multiple wireless devices may operate in a half-duplex mode relative to the IoT device 205. For example, (e.g., not depicted) , an IoT device 205 may receive FL 220, CW 225, or both, from a UE 115 and may transmit BL 215 to a network entity or, alternatively, the IoT device 205 may receive the FL 220, the CW 225, or both, from the network entity 105 and may transmit the BL 215 to the UE 115. In some cases, the multiple wireless devices may establish a communication link (e.g., Uu link) between themselves. In some cases (e.g., mmWave) , the CW 225 may be associated with (e.g., communicated via) a narrow directional beam to provide increase power gain (e.g., as compared to a broader beam) to enable energy harvesting in the IoT device 205. Additionally, the narrow directional beam may reduce interference caused by the CW 225.
[0095] Additionally, or alternatively, an IoT device 205 may communicate directly with a network entity 105 or indirectly via a UE 115. For example, in some cases, as depicted in FIG. 2A, the IoT device 205-a may communicate directly (e.g., and bidirectionally) with the network entity 105-a. In some other cases, as depicted in FIG. 2B, the IoT device 205-b may communicate with the UE 115-b, which may operate as an intermediate node (e.g., an intermediate UE 115) between the IoT device 205-b and the network entity 105-b. In either cases, uplink 210 (e.g., uplink signaling, uplink transmissions, uplink messages) communicated by one or more UEs 115 may cause interference, such as CLI 230, in FL 220. That is, uplink 210 transmitted by one or more UEs 115 may interfere with FL 220 received (e.g., or to be received) by an IoT device 205, such that the IoT device 205 may be unable to successfully receive the FL 220 (e.g., degrading FL reception performance in the IoT device 205-a) .
[0096] In some cases, the CLI 230 may be intra-cell CLI 230 (e.g., intra-cell interference) between uplink 210 and FL 220. For example, as depicted in FIG. 2A, one or more first resources associated with uplink 210-a may conflict (e.g., at least partially overlap with) one or more second resources associated with the FL 220-a, the CW 225-a, or both, such that transmission of the uplink 210-a by the UE 115-a may result in CLI 230-a at the IoT device 205-a during reception of the FL 220-a. Similarly, as depicted in FIG. 2B, one or more third resources associated with uplink 210-c may conflict (e.g., at least partially overlap with) one or more fourth resources associated with the FL 220-b, the CW 225-b, or both, such that transmission of the uplink 210-b by the UE 115-c may result in CLI 230-c at the IoT device 205-b during reception of the FL 220-b (e.g., degrading FL reception performance in the IoT device 205-b) .
[0097] Additionally, or alternatively, the CLI 230 may be due to one or more intra-UE collisions between uplink 210 and FL 220 (e.g., at an intermediate UE 115) . For example, as depicted in FIG. 2B, the UE 115-b may be an intermediate UE 115-b between the IoT device 205-b and the network entity 105-b. Thus, when one or more fifth resources associated with uplink 210-b conflict with (e.g., at least partially overlap with, are the same as) one or more sixth resources associated with the FL 220-b, the CW 225-b, or both, transmission of the uplink 210-b by the UE 115-b may result in CLI 230-b at the IoT device 205-b during reception of the FL 220-b (e.g., degrading the FL reception performance in the IoT device 205-b) . However, in some cases, the one or more fifth resources (e.g., CLI source) and the one or more sixth resources (FL source) may be scheduled (e.g., managed) by the UE 115-b, such that the UE 115-b may perform one or more CLI mitigation techniques (e.g., UE-self implementation can avoid or remove impacts of the CLI 230-b) .
[0098] Conversely, for intra-cell CLI 230, FL 220 and uplink 210 (e.g., resulting in CLI 230) may be associated with two different wireless devices (e.g., two separate nodes) . That is, the uplink 210 may be transmitted by a UE 115 that is not transmitting the FL 220 received by an IoT device 205. For example, as depicted in FIG. 2A, the UE 115-a may transmit the uplink 210-a (e.g., resulting in the CLI 230-a) but the IoT device 205-a may receive the FL 220-a from the network entity 105-a (e.g., the UE 115-a and the network entity 105-a may be separate nodes) . Similarly, as depicted in FIG. 2B, the UE 115-c may transmit the uplink 210-c (e.g., resulting in the CLI 230-c) but the IoT device 205-b may receive the FL 220-b from the network entity 105-b (e.g., the UE 115-c and the network entity 105-b may be separate nodes) . Thus, in either case, the UE 115 (e.g., the UE 115-a or the UE 115-c) may be unable to perform one or more CLI mitigation techniques to mitigate the respective CLI 230.
[0099] Additionally, in such case, the IoT devices 205 may be unable to perform a CLI mitigation procedure (e.g., when the IoT devices 205 are victim devices) . That is, the IoT devices 205 may be unable to receive configuration information (e.g., a Layer 3 resource configuration) indicating CLI one or more resources (e.g., CLI RSRP or Cli RSSI resources) due to a complexity of the configuration information. Additionally, or alternatively, the IoT devices 205 may not be capable of performing CLI measurements (e.g., RSSI measurements, RSRP measurements) , nor reporting the CLI measurements. Thus, the IoT device 205 may experience degraded performance due to CLI.
[0100] Accordingly, techniques described herein may enable a network entity 105, such as the network entity 105-a or the network entity 105-b, to determine one or more aggressor UEs 115, such as the UE 115-a, the UE 115-c, the UE 115-b, or any combination thereof, causing CLI 230 at an IoT device 205, such as the IoT device 205-a or the IoT device 205-b, and reschedule the one or more aggressor UEs 115 to mitigate the CLI 230. For example, as described further with reference to FIG. 3, the network entity 105 may identify that an IoT device 205 may be experiencing CLI 230 (e.g., based on network implementation) . Thus, to identify one or more aggressor UEs 115 causing the CLI 230, the network 105 may transmit, to multiple UEs 105, a control message indicating one or more resources used by the IoT 205 device to transmit BL 215, which may be referred to as BL resources. Each of the multiple UEs 115 may measure the one or more BL resources to generate one or more channel quality metrics and may transmit, to the network entity 105, a report indicative of the one or more channel quality metrics. Thus, the network entity 105 may determine one or more aggressor UEs 115 from the multiple UEs 115 based on the report channel quality metrics (e.g., and based on channel reciprocity) and may reschedule the one or more aggressor UEs 115 to mitigate the CLI 230.
[0101] FIG. 3 shows an example of a wireless communications system 300 that supports techniques for identifying and mitigating CLI in IoT scenarios in accordance with one or more aspects of the present disclosure. In some cases, the wireless communications system 300 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications systems 200, or both. For example, the wireless communications system 300 may include one or more UEs 115 (e.g., a UE 115-d and a UE 115-e) and one or more network entities 105, which may be examples of the corresponding devices as described herein.
[0102] In some cases, as described with reference to FIGs. 2A and 2B, the wireless communications system 300 may support techniques to enable a network entity 105 to determine one or more aggressor UEs 115 causing CLI 330 at an IoT device 305 and reschedule the one or more aggressor UEs 115 to mitigate the CLI 330. For example, in some cases, the IoT device 305 may communicate (e.g., with a UE 115 or a network entity 105) FL, CW, and BL 315 via a first spectrum (e.g., NR spectrum) , where the first spectrum is also used by one or more UEs 115, such as the UE 115-d, the UE 115-e, and the UE 115-f, to perform uplink transmissions (e.g., Uu uplink transmissions) , such that the uplink transmissions performed by at least a subset of the one or more UEs 115 may cause CLI 330 in the FL and CW communicated by the IoT device 305 (e.g., FL and CW reception) . In other words, IoT tones used for communication of the FL and CW may be within an uplink BWP (e.g., within an uplink spectrum) , such that reception of FL by the IoT device 305 may be impacted by uplink signals transmitted by the one or more UEs 115.
[0103] Thus, the network entity 105 may determine one or more aggressor UEs 115 from the one or more UEs 115 sharing the first spectrum with the IoT device 305. For example, based on channel reciprocity, if one UE 115 detects a large (e.g., exceeding a threshold) receive power strength from the IoT device 305, the IoT device 305 may also detect the receive power strength (e.g., as CLI 330) from the UE 115 when there is a conflict between uplink resources used by the UE 115 and IoT tones used by the IoT device 305 (e.g., IoT CW and FL tones) . Thus, based on the channel reciprocity, to estimate CLI 330 experienced by the IoT device 305, and to identify a source of the CLI 330, the IoT device 305 may transmit a signal and candidate aggressors UEs 115 may estimate the receive power.
[0104] For example, as depicted in FIG. 3, the UE 115-d, the UE 115-e, and the UE 115-f may be located within a threshold proximity to the IoT device 305, such that the UE 115-d, the UE 115-e, and the UE 115-f may be candidate aggressor UEs 115. In such cases, each of the candidate aggressor UEs 115 may additionally be associated with one or more uplink resources that conflict with one or more IoT tones associated with the IoT device 305.
[0105] Additionally, a network entity 105 (e.g., communicating with the candidate aggressor UEs 115) may identify (e.g., detect or determine via network implementation) that the IoT device 305 may be experiencing CLI 330 (e.g., interference exceeding a threshold interference) during FL reception, CW reception, or both (e.g., via the one or more IoT tones) . For example, the network entity 105 may identify a periodical failure pattern of IoT communications (e.g., FL reception, CW reception, or both) and may determine that the IoT device 305 is experiencing CLI 330 based on the periodical failure pattern. As such, the network entity 105 may trigger interference management for the IoT device 305 by transmitting, to each of the candidate aggressor UEs 115, a control message indicating (e.g., configuring) one or more resources associated with a BL communication link of the IoT device 305 (e.g., between the IoT device 305 and the network entity 105) , which may be referred to as BL resources (e.g., BL tones) . That is, the one or more BL resources (e.g., one or more BL tones) may be used by the IoT device 305 to transmit BL 315 to the network entity 105.
[0106] In some cases, the network entity 105 may additionally indicate one or more receive beams associated with each candidate aggressor UE 115 with which each candidate aggressor UE 115 is to measure the BL via the one or more BL resources (e.g., CLI resources) . In some other cases, each candidate aggressor UE 115 may measure the BL via the one or more BL resources using a respective transmit beam. In such cases (e.g., based on channel reciprocity) , CLI 330 experienced by the IoT device 305 may be based on transmission of uplink signaling by a candidate aggressor UE 115 such that, to align the channel reciprocity, the candidate aggressor UE 115 may measure the BL via the one or more BL resources using a transmit beam used to transmit the uplink signaling.
[0107] Thus, each of the candidate aggressor UEs 115 may measure BL 315 transmitted by the IoT device 305 via the one or more BL resources (e.g., in the one or more BL tones) to generate one or more channel quality metrics, such as RSSI, RSRP, or both, and may report an indication of the one or more channel quality metrics to the network entity 105. For example, the UE 115-d may measure a large RSRP (e.g., relative to the UE 115-e and the UE 115-f) which may indicate that uplink signals transmitted by the UE 115-d may cause strong CLI 330-a (e.g., relative to the UE 115-e and the UE 115-f) at the IoT device 305 when the uplink signals transmitted by the UE 115-d conflict (e.g., at least partially overlap) with FL reception, CW reception, or both, by the IoT device 305. Conversely, each of the UE 115-e and the UE 115-f may measure a small RSRP (e.g., relative to the UE 115-d) or may be incapable of measuring the BL 315 in the one or more BL resources which may indicate uplink signals transmitted by the UE 115-e and the UE 115-f may cause weak CLI 330-b and CLI 330-c (e.g., relative to the UE 115-e and the UE 115-f) , respectively, or no CLI 330-b and CLI 330-c, respectively, at the IoT device 305 when the uplink signals transmitted by the UE 115-e and the UE 115-f conflict with FL reception, CW reception, or both, by the IoT device 305.
[0108] Additionally, the candidate aggressor UEs 115 (e.g., the UE 115-d, the UE 115-e, and the UE 115-f) may report an indication of the generated channel quality metrics (e.g., the measured RSRPs) to the network entity 105, such that the network entity 105 may determine which of the candidate aggressor UEs 115 are aggressor UEs 115 causing CLI 330 (e.g., CLI 330 exceeding a threshold CLI) at the IoT device 305. In some cases, each of candidate aggressor UEs 115 may transmit a CLI report (e.g., Layer 1 CLI report) indicative of the one or more respective channel quality metrics. Additionally, or alternatively, the CLI report may indicate one or more CLI metrics generated (e.g., determined) based on the respective channel quality metrics, as described further with reference to FIG. 4. Additionally, in some cases, transmission of the CLI report may be event triggered. For example, a candidate aggressor UE 115 may transmit a CLI report indicative of CLI 330 based on the CLI 330 exceeding the threshold CLI.
[0109] In some cases, the network entity 105 may identify that the UE 115-d is the aggressor UE 115 based on one or more uplink resource associated with communication of uplink signaling by the UE 115-d conflicting (e.g., at least partially overlapping) with one or more FL resources associated with FL reception by the IoT device 305 and based on the CLI 330-a (e.g., the UE 115-d detecting a strong power in the one or more BL resources) . In such cases, based on identifying that the UE 115-d is the aggressor UE 115, the network entity may reschedule one or more uplink resources associated with the UE 115-d (e.g., that conflict with one or more CW resources, one or more FL resources, or both, associated with the IoT device 305) to remove or degrade the CLI 330-a. Conversely, in some other cases, the network entity 105 may identify that the UE 115-d is not the aggressor UE 115 based on no resources associated with communication of uplink signaling by the UE 115-d conflicting with one or more FL resources associated with FL reception by the IoT device 305 (e.g., the one or more resources associated with the UE 115-d are independent from the one or more FL resources) despite the CLI 330-a (e.g., even though the UE 115-d detected the strong power in the one or more BL resources) .
[0110] In some cases, the candidate aggressor UEs 115 (e.g., the UE 115-d, the UE 115-e, and the UE 115-f) may be UEs 115 associated with one or more uplink resources that conflict (e.g., at least partially overlap) with one or more CW resources, one or more FL resources, or both, associated with the IoT device 305 (e.g., IoT FL tones, IoT CW tones, or both) , may be UEs 115 scheduled in a same cell as the IoT device 305, may be UEs 115 within the threshold proximity of the IoT device 305, may be UEs 115 within a second threshold proximity of an intermediate UE 115 communicating with the IoT device 305, or any combination thereof. In such cases, the network entity 105 may group the candidate aggressor UEs 115 and may configure one or more control information bits (e.g., DCI bits) to schedule the group of candidate aggressor UEs 115 and to indicate which UEs 115 of the group of candidate aggressor UEs 115 are to be triggered for measurement of the one or more BL resources.
[0111] Additionally, as described previously, the one or more BL resources indicated to the candidate aggressor UEs 115 may be for measurement (e.g., RSSI measurement, RSRP measurement, or both) of the BL 315 transmitted by the UE 115 to the network entity 105. In other words, the candidate aggressor UEs 115 may not (e.g., may refrain from) perform BL decoding of the BL 315. Additionally, or alternatively, as described with reference to FIG. 4, the control message (e.g., transmitted by the network entity 105) indicating the one or more BL resources (e.g., BL tones) may include configuration information (e.g., a BL resource configuration) indicating any combination of one or more resource block (RB) indices, a tone index (e.g., if a single tone is configured for the BL 315) , a tone index list (e.g., if multiple tones are configured for the BL 315) , and one or more tone hopping patterns (e.g., if hopping is enable in different slots) . In some cases, the control message may be a MAC-CE message while, in some other cases, the control message may be an RRC message.
[0112] FIG. 4 shows an example of tone allocations 400 (e.g., a tone allocation 400-a, a tone allocation 400-b, and a tone allocation 400-c) that supports techniques for identifying and mitigating CLI in IoT scenarios in accordance with one or more aspects of the present disclosure. In some cases, the tone allocations 400 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications systems 200, the wireless communications system 300, or any combination thereof. For example, the tone allocations 400 may be implemented by one or more UEs 115 and one or more network entities 105, which may be examples of the corresponding devices as described herein.
[0113] As described with reference to FIG. 3, a network entity 105 may transmit a control message indicating one or more BL tones 410 (e.g., one or more BL resources) associated with an IoT device during which multiple candidate aggressor UEs 115 are to measure one or more channel quality metrics. For example, as depicted in the tone allocation 400-a, the network entity 105 may transmit a control message indicating a BL tone 410-a (e.g., tone 6) in an RB 405-a, a BL tone 410-b (e.g., tone 3) in an TB 405-b, a BL tone 410-c (e.g., tone 10) in an TB 405-c, and a BL tone 410-d (e.g., tone 3) in an RB 405-d. Thus, each of the multiple candidate aggressor UEs 115 may measure the one or more channel quality metrics associated with BL transmitted in each BL tone 410 and may transmit a report indicative of the one or more channel quality metrics to the network entity, such that the network entity 105 may identify one or more aggressor UEs 115 from the multiple candidate aggressor UEs 115 based on the channel quality metrics report by the candidate aggressor UEs 115. In such cases, the aggressor UEs 115 may be associated with CLI experienced by (e.g., at) the IoT device during reception of CW, reception of FL, or both.
[0114] In some cases, when the CW is transmitted to enable the IoT device 205 to transmit BL (e.g., is backscattering CW) , the CW (e.g., and FL) and the BL may share a same set of one or more tones. Thus, to enable candidate aggressor UEs 115 to measure the one or more channel quality metrics in the one or more BL tones 410, the network entity 105 may disable CW transmissions, FL transmissions, or both, to the IoT device (e.g., by one or more UEs 115, one or more network entities 105, or both) during the one or more BL tones 410 to support the measurement of the one or more channel quality metrics being based on BL transmitted via the one or more BL tones 410 (e.g., and not also based on other signaling transmitted by the one or more UEs 115, the one or more network entities 105, or both) . In some other cases, when the CW is transmitted to provide energy to the IoT device (e.g., is energy-transfer CW) , the CW (e.g., and FL) and the BL may be associated with different tones. Thus, the network entity 105 may not disable may disable CW transmissions, FL transmissions, or both, to the IoT device during the one or more BL tones 410.
[0115] In some cases, the one or more channel quality metrics may be RSRP. Thus, to measure (e.g., generate, determine) the RSRP to report to the network entity 105, a candidate aggressor UE 115 may measure a first signal power (e.g., P1) via a BL tone 410, such as a BL tone 410-e in an RB 405-e, and may measure a second signal power (e.g., P2) via a blank tone 415, such as a blank tone 415-a in the RB 405-a, and may generate the RSRP based on a difference between the first signal power and the second signal power (e.g., RSRP=P1-P2) . In such cases, the network entity 105 may indicate, via the control message indicating the one or more BL tones 410, one or more blank tones 415 (e.g., blank resources) , where each blank tone 415 of the one or more blank tones 415 is associated with a BL tone 410 of the one or more BL tones 410 (e.g., are in a same RB 405, such as the RB 405-e) and where no BL signals are transmitted by the IoT device in the one or more blank tones 415.
[0116] In some examples, the RSRP to reported to the network entity 105 may be based on multiple RBs 405. For example, as depicted in the tone allocation 400-a, the network entity 105 may configure a BL tone 410 (e.g., tonej) in each RB 405 of multiple RBs 405 for BL transmission with hopping and may configure other tones (e.g., all other tones) in each RB 405 as blank tones 415. Thus, a candidate aggressor UE 115 may calculate the RSRP according to the following Equation 1:
[0117] where Pj may represent a signal power of the tonej and Pindex may represent a signal power of the blank tones 415. Additionally, “mean” may indicate an average value of the different between Pj and across multiple RBs 405 (e.g., slots) .
[0118] In some cases, one or more blank tones 415 in an RB 405 may within a threshold tone proximity of a BL tone 410 in the RB 405 such that the one or more blank tones 415 and the BL tone 410 may be associated with same background interference and noise. In some cases (e.g., FDD pattern) , as depicted in the tone allocation 400-b, the one or more blank tones 415 may be other unused tones in an RB 405. For example, the BL tone 410-e (e.g., tone 6) and the blank tone 415-a (e.g., tone 6) in the RB 405-e may be associated with the same background interference and noise.
[0119] In some other cases, as depicted in the tone allocation 400-c, the one or more blank tones 415 may be a same tone in other adjacent slots. For example, a BL tone 410-f (e.g., tone 6) in an RB 405-f, a blank tone 415-b (e.g., tone 6) in an RB 405-g, a BL tone 410-g (e.g., tone 6) in an RB 405-h, and a blank tone 415-c (e.g., tone 6) in an RB 405-j may be associated with the same background interference and noise. In such cases, the network entity 105 may disable BL in the RB 405-g and the RB 405-j based on the RB 405-g and the RB 405-j including blank tones 415 and may enable BL in the RB 405-f and the RB 405-h based on the RB 405-f and the RB 405-h including BL tones 410.
[0120] In some other examples, the one or more channel quality metrics may be RSSI. In such cases, CLI experience by the IoT device (e.g., indicated by RxPowerUE→IoT (dB) ) may be calculated according to the following Equation 2:
[0121] RxPowerUE→IoT (dB) =TxPowerUE-PathlossUE→IoT-others (2)
[0122] where TxPowerUE may represent a transmit power of a candidate aggressor UE 115, PathlossUE→IoT may represent a pathloss from the candidate aggressor UE 115 to the IoT device, and others may represent other sources of interference.
[0123] Additionally, RSSI measured by the candidate aggressor UE 115 (e.g., indicated by RxPowerIoT→UE (dB) ) may be calculated according to the following Equation 3:
[0124] RxPowerIoT→UE (dB) =TxPowerIoT-PathlossIoT→UE-others (3)
[0125] where TxPowerIoT may represent a transmit power of the IoT device, PathlossIoT→UEmay represent a pathloss from the IoT device to the candidate aggressor UE 115, and others may represent the other sources of interference.
[0126] Thus, the CLI experience by the IoT device may also be calculated (e.g., by the network entity 105, a candidate aggressor UE 115, or both) according to the following Equation 4:
[0127]
[0128] Thus, the network entity 105 (e.g., or a candidate aggressor UE 115) may calculate the CLI experienced by the IoT device (e.g., RxPowerUE→IoT (dB) ) based on the transmit power of the candidate aggressor UE 115 (e.g., TxPowerUE) , the transmit power of the IoT device (e.g., TxPowerIoT) , and the RSSI measured by the candidate aggressor UE 115 (e.g., RxPowerIoT→UE) . In such cases, the transmit power (e.g., assumed transmit power, dynamically power controlled transmit power) of the candidate aggressor UE 115 may be reported to the network entity 105 by the candidate aggressor UE 115. Additionally, in some cases (e.g., the IoT device is associated with a dedicated transmit power provided by energy transfer CW) , the IoT device may determine (e.g., self-determine) and report the transmit power of the IoT device to the network entity via BL. In some other cases (e.g., the IoT device is associated with a backscattered transmit power provided by backscattering CW) , the transmit power of the IoT device may be a constant (e.g., defined) value or may be estimated according to the following Equation 5:
[0129] TxPowerIot=TxPowerCW-PathlossCW-BackscatterLossIoT (5)
[0130] where TxPowerCW may represent a transmit power associated with CW (e.g., the backscattering CW) , PathlossCW may represent a pathloss associated with the CW, and BackscatterLossIoT may represent a backscatter loss associated with the IoT device.
[0131] Additionally, or alternatively, the candidate aggressor UE 115 may calculate the CLI experienced by the IoT device (e.g., RxPowerUE→IoT (dB) ) according to Equation 4 and may report the calculated CLI (e.g., rather than or in combination with the RSSI measured by the candidate aggressor UE 115) . In such cases, the candidate aggressor UE 115 may be aware of the transmit power of the IoT device (e.g., TxPowerIoT) based on signaling from the IoT device, signaling from the network entity 105, the constant value, the value estimated according to Equation 5, or any combination thereof.
[0132] FIG. 5 shows an example of a process flow 500 that supports techniques for identifying and mitigating CLI in IoT scenarios in accordance with one or more aspects of the present disclosure. In some cases, the process flow 500 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications systems 200, the wireless communications system 300, the tone allocations 400, or any combination thereof. For example, the process flow 500 may include one or more UEs 115 (e.g., a UE 115-g and a UE 115-g) and one or more network entities 105 (e.g., a network entity 105-c and a network entity 105-d) , which may be examples of the corresponding devices as described herein. In the following description of the process flow 500, the operations between wireless devices (e.g., an IoT device, the UE 115-g, the UE 115-h, the network entity 105-c, and the network entity 105-d) may be communicated in a different order than the example order shown, or the operations performed by the wireless devices may be performed in different orders or at different times. Some operations may also be omitted from the process flow 500, and other operations may be added to the process flow 500.
[0133] In some cases, at 510, the network entity 105-c may detect (e.g., estimate) interference experienced by an IoT device 505 during FL reception, CW reception, or both (e.g., in a backscatter communication link with the IoT device 505) . Additionally, or alternatively, the network entity 105-c may detect a failure in communications with the IoT device 505 which may indicate the IoT device 505 is experiencing (e.g., is subject to) interference.
[0134] At 515, the network entity 105-c may transmit, to each candidate aggressor UE 115 in a set of candidate aggressor UEs 115, such as the UE 115-g and the UE 115-h, a first control message (e.g., RRC message, MAC-CE message) indicative of configuration information for generating (e.g., measuring) one or more channel quality metrics (e.g., RSRP, RSSI, or both) associated with the backscatter communication link between the IoT device 505 and the network entity 105-c (e.g., based on detecting the interference) . In such cases, the configuration information may be indicative of one or more first resources (e.g., BL resources, BL tones) associated with the backscatter communication link. Additionally, in some cases, the network entity 105-c may transmit the configuration information indicative of the one or more first resources to one or more additional network devices, such as the network entity 105-d, to indicate to the one or more additional network devices to refrain from communicating (e.g., transmitting) during the one or more first resources.
[0135] In some cases, to each candidate aggressor UE 115 in the set of candidate aggressor UEs 115 may receive the first control message based on one or more respective third resources associated with transmissions by a respective candidate aggressor UE 115 at least partially overlapping with one or more fourth resources associated with receptions by the IoT device 505, based each candidate aggressor UE 115 and the IoT device 505 communicating with the network entity 105-c (e.g., a same cell) , based on a respective first proximity of each candidate aggressor UE 115 to the IoT device 505, based on a respective second proximity of each candidate aggressor UE 115 to an additional UE 115 communicating with the IoT device 505, or any combination thereof. Additionally, or alternatively, the set of candidate aggressor UEs 115 may be associated with a group, such that the first control message includes an indication of the group.
[0136] In some examples, the configuration information may indicate the one or more first resources via any combination of one or more RB indices, one or more tone indices, one or more tone index lists, one or more tone hopping patterns, or any combination thereof.
[0137] Thus, in some cases, at 520, the network entity 105-d may disable transmissions during the one or more first resources.
[0138] At 525, each candidate aggressor UE 115 from the set of candidate aggressor UEs 115 may generate the one or more channel quality metrics based on measuring the one or more first resources associated with the backscatter communication link (e.g., based on receiving the first control message) . For example, at 525-a, the UE 115-g may measure the one or more first resources to generate one or more first channel quality metrics and, at 525-b, the UE 115-h may measure the one or more first resources to generate one or more second channel quality metrics. Additionally, each candidate aggressor UE 115 from the set of candidate aggressor UEs 115 may refrain from decoding the one or more first resources based on the one or more first resources being for measuring the one or more channel quality metrics.
[0139] In some cases, each candidate aggressor UE 115 from the set of candidate aggressor UEs 115 may measure a first signal power associated with the one or more first resources, may measure a second signal power associated with one or more second resources, and may calculate a difference between the first signal power and the second signal power, where the one or more channel quality metrics are based on the difference. In such cases, the one or more second resources may be free from transmissions by the IoT device 505, may be indicated via the configuration information, or both. In some examples, the one or more first resources may be associated with one or more first tones in a first RB and the one or more second resources may be associated with one or more second tones in the first RB. In some other examples, the one or more first resources may be associated with the one or more first tones in the first RB and the one or more second resources may be associated with the one or more first tones in a second RB. In such cases, the second RB may be an RB in which no signaling is communicated by the candidate aggressor UEs 115, the IoT device 505, one or more additional wireless devices, or any combination thereof.
[0140] Additionally, or alternatively, each candidate aggressor UE 115 from the set of candidate aggressor UEs 115 may measure the one or more first resources via a respective first beam, where the configuration information is indicative of the first beam, where the first beam is a respective transmit beam associated with each candidate aggressor UE 115, or both
[0141] At 530, each candidate aggressor UE 115 from the set of candidate aggressor UEs 115 may transmit, to the network entity 105-c, a report indicative of the one or more respective channel quality metrics. For example, at 530-a, the UE 115-g may transmit a first report indicative of the one or more first channel quality metrics and, at 530-b, the UE 115-g may transmit a second report indicative of the one or more second channel quality metrics. In some cases, each candidate aggressor UE 115 from the set of candidate aggressor UEs 115 may transmit the respective report based on one or more trigger events. For example, the one or more trigger events many include the one or more channel quality metrics exceeding a threshold.
[0142] Thus, the network entity 105-c may identify one or more aggressor UEs 115, such as the UE 115-g, from the set of candidate aggressor UEs 115 based on the one or more respective channel quality metrics associated with each candidate aggressor UE 115 from the set of candidate aggressor UEs 115 and, at 535, may transmit, to each of the one or more aggressor UEs 115 and based on the one or more respective channel quality metrics, a second control message rescheduling one or more second resources allocated to each of the one or more aggressor UEs 115.
[0143] In some cases, each of the one or more aggressor UEs 115 may receive the second control message based on a CLI metric associated with the respective aggressor UE 115 exceeding a threshold, based on the CLI metric being greatest out of multiple CLI metrics associated with the set of candidate aggressor UEs 115, or both. In such cases, the CLI metric may be based on the one or more channel quality metrics, a first transmit power of the IoT device 505, and a second transmit power of the respective aggressor UE 115. Additionally, or alternatively, each of the one or more aggressor UEs 115 may receive the second control message based on one or more respective third resources associated with transmissions by a respective aggressor UE 115 at least partially overlapping with one or more fourth resources associated with receptions by the IoT device 505.

The device 905 may be an example of or include components of a device 605, a device 705, or a UE 115 as described herein. The device 905 may communicate (e.g., wirelessly) with one or more other devices (e.g., network entities 105, UEs 115, or a combination thereof) . The device 905 may include components for bi-directional voice and data communications including components for transmitting and receiving communications, such as a communications manager 920, an input / output (I / O) controller, such as an I / O controller 910, a transceiver 915, one or more antennas 925, at least one memory 930, code 935, and at least one processor 940.

[0286] The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration” and not “preferred” or “advantageous over other examples. ” The detailed description includes specific details for the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some figures, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.
