INTERFERENCE MEASUREMENT AND REPORTING FOR AMBIENT WIRELESS DEVICES
[0001] FIELD OF TECHNOLOGY
[0002] The present disclosure relates to wireless communication, including interference measurement and reporting for ambient wireless devices.BACKGROUND
[0003] 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 network nodes, each supporting wireless communication for communication devices, which may be known as user equipment (UE) .SUMMARY
[0004] The described techniques relate to improved methods, systems, devices, and apparatuses that support interference measurement and reporting for ambient wireless devices. For example, the described techniques provide for a first wireless communications device, such as a user equipment (UE) , to measure cross-link interference (CLI) within networks supporting ambient Internet of Things (A-IoT) devices. For example, a network node may transmit a message to configure a UE with one or more CLI measurement resources that may be a subset of one or more uplink frequency division duplex (UL-FDD) resources, one or more downlink (DL) FDD (DL-FDD) resources, one or more time division duplex (TDD) resources, or any combination thereof. The UE may perform one or more CLI measurements using the resources to record interference from different devices at an ambient link between the UE and an A-IoT device for which the UE is configured as a reader. The UE may transmit a measurement report indicating the measured CLI, and the network node may schedule or adjust one or more communications (e.g., or communications parameters) based on the report to reduce, mitigate, or prevent CLI at the UE, which may improve a quality of one or more communications. In some examples, the UE may indicate a capability to measure CLI in FDD or TDD. Further, a network node may communicate ambient link resources with another network node to avoid collision between cells. Additional communications may also be supported by a network to facilitate CLI for FDD configurations, including CLI measurement activation indications between UEs and network nodes, as well as occasion activation communications between readers and A-IoT devices to reduce reflected interference.

[0049] Some wireless communications systems may include one or more Internet of Things (IoT) devices, including ambient Internet of things (A-IoT) devices which may harvest energy from different ambient resources. For example, a wireless communication device, such as a user equipment (UE) , may function as a reader of an A-IoT device (e.g., a tag) by transmitting a continuous wave or carrier wave (CW) that the A-IoT device may use to power a response backscatter signal. UEs may further receive in downlink or transmit in uplink via a Uu channel with a network node. In a time division duplex (TDD) configured network, however, simultaneous uplink (UL) communications from one UE may interfere with downlink communications at another UE, which may be referred to as cross-link interference (CLI) . In a frequency division duplex (FDD) configuration, CLI may be avoided via separation of UL and downlink (DL) transmissions. However, in networks supporting A-IoT devices, an ambient link (e.g., link with an A-IoT device) of a reader UE may experience CLI from transmitting devices in UL (e.g., UEs) or in DL (e.g., base stations) as a network node may not be aware of one or more ambient communications. UL transmissions from one or more UEs sent to a network node may also trigger additional backscatter communications from nearby A-IoT devices, causing reflection, or propagation, of CLI to the reader UE. Although CLI may be defined for measurement in TDD configurations, such measurement may not yet be defined in relation to FDD configurations for A-IoT networks, which may result in wasted resources and poor quality in communications.
[0050] Techniques described herein enable the measurement of CLI within networks supporting IoT devices, including A-IoT devices. For example, a network node may configure a UE with one or more CLI measurement resources, where the resources may be a subset of one or more UL-FDD, DL-FDD, or TDD resources. In some cases, the resources may be a subset of one or more ambient link resources of an UL-FDD spectrum for A-IoT device communication. The UE may perform one or more CLI measurements to record interference from different devices received via the configured measurement resources. After the UE transmits a report of the measured CLI, a network node may schedule or adjust one or more communications to reduce CLI at the UE, improving a quality of one or more communications. In some examples, the UE may indicate a capability to measure CLI in FDD. Further, a network node may communicate ambient link resources with another network node to avoid collision between cells. Additional communications may also be supported by a network to facilitate CLI for FDD configurations, including CLI measurement activation indications between UEs and network nodes, as well as on and off configuration communications between readers and A-IoT devices to reduce CLI caused by reflection.
[0051] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further illustrated by and described with reference to wireless communications systems, resource diagrams, and process flows that relate to interference measurement and reporting for ambient wireless devices. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to interference measurement and reporting for ambient wireless devices.
[0052] FIG. 1 shows an example of a wireless communications system 100 that supports interference measurement and reporting for ambient wireless devices 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 nodes 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.
[0053] The network nodes 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 node 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 nodes 105 and UEs 115 may wirelessly communicate via communication link (s) 125 (e.g., a radio frequency (RF) access link) . For example, a network node 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network node 105 may establish the communication link (s) 125. The coverage area 110 may be an example of a geographic area over which a network node 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs) .
[0054] 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 nodes 105) , as shown in FIG. 1.
[0055] 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 node 105 (e.g., any network node 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 node 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 node 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 node 105, and the third node may be a network node 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 node 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network node 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 node 105 also discloses that a first node is configured to receive information from a second node.
[0056] In some examples, network nodes 105 may communicate with a core network 130, or with one another, or both. For example, network nodes 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 nodes 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 nodes 105) or indirectly (e.g., via the core network 130) . In some examples, network nodes 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.
[0057] One or more of the network nodes 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 node 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 node (e.g., a network node 105 or a single RAN node, such as a base station 140) .
[0058] In some examples, a network node 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 nodes (e.g., network nodes 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 node 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 nodes 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network nodes 105 may be located in distributed locations (e.g., separate physical locations) . In some examples, one or more of the network nodes 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) ) .
[0059] 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 adaption 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 nodes (e.g., one or more of the network nodes 105) that are in communication via such communication links.
[0060] 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 nodes 105 (e.g., network nodes 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 node 105 or base station 140 (such as a donor network node 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.
[0061] 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 node 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) .
[0062] 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 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.
[0063] 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 nodes 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.
[0064] The UEs 115 and the network nodes 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 FDD and TDD component carriers. Communication between a network node 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network node 105. For example, the terms “transmitting, ” “receiving, ” or “communicating, ” when referring to a network node 105, may refer to any portion of a network node 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 nodes, such as one or more of the network nodes 105) .
[0065] In some examples, such as in a carrier aggregation configuration, a carrier may have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute RF channel number (EARFCN) ) and may be identified according to a channel raster for discovery by the UEs 115. A carrier may be operated in a standalone mode, in which case initial acquisition and connection may be conducted by the UEs 115 via the carrier, or the carrier may be operated in a non-standalone mode, in which case a connection is anchored using a different carrier (e.g., of the same or a different RAT) .
[0066] The communication link (s) 125 of the wireless communications system 100 may include downlink transmissions (e.g., forward link (FL) transmissions) from a network node 105 to a UE 115, uplink transmissions (e.g., return link transmissions) from a UE 115 to a network node 105, or both, among other configurations of transmissions. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode) .
[0067] A carrier may be associated with a particular bandwidth of the RF spectrum and, in some examples, the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system 100. For example, the carrier bandwidth may be one of a set of bandwidths for carriers of a particular RAT (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz) ) . Devices of the wireless communications system 100 (e.g., the network nodes 105, the UEs 115, or both) may have hardware configurations that support communications using a particular carrier bandwidth or may be configurable to support communications using one of a set of carrier bandwidths. In some examples, the wireless communications system 100 may include network nodes 105 or UEs 115 that support concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating using portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.
[0068] 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 (RE) 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 RE 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 REs (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.
[0069] The time intervals for the network nodes 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) .
[0070] 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.
[0071] 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) ) .
[0072] 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) .
[0073] A network node 105 may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a network node 105 (e.g., using a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID) , a virtual cell identifier (VCID) ) . In some examples, a cell also may refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) over which the logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the network node 105. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with coverage areas 110, among other examples.
[0074] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by the UEs 115 with service subscriptions with the network provider supporting the macro cell. A small cell may be associated with a network node 105 operating with lower power (e.g., a base station 140 operating with lower power) relative to a macro cell, and a small cell may operate using the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to the UEs 115 with service subscriptions with the network provider or may provide restricted access to the UEs 115 having an association with the small cell (e.g., the UEs 115 in a closed subscriber group (CSG) , the UEs 115 associated with users in a home or office) . A network node 105 may support one or more cells and may also support communications via the one or more cells using one or multiple component carriers.
[0075] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT) , enhanced mobile broadband (eMBB) ) that may provide access for different types of devices.
[0076] In some examples, a network node 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 node (e.g., a network node 105) . In some other examples, overlapping coverage areas, such as a coverage area 110, associated with different technologies may be supported by different network nodes (e.g., the network nodes 105) . The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network nodes 105 support communications for coverage areas 110 (e.g., different coverage areas) using the same or different RATs.
[0077] Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communications (e.g., a mode that supports one-way communication via transmission or reception, but not transmission and reception concurrently) . In some examples, half-duplex communications may be performed at a reduced peak rate. Other power conservation techniques for the UEs 115 may include entering a power saving deep sleep mode when not engaging in active communications, operating using a limited bandwidth (e.g., according to narrowband communications) , or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type that is associated with a defined portion or range (e.g., set of subcarriers or resource blocks (RBs) ) within a carrier, within a guard-band of a carrier, or outside of a carrier.
[0078] 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.
[0079] 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 node 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 node 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network node 105 or may be otherwise unable to or not configured to receive transmissions from a network node 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 node 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 node 105.
[0080] In some systems, a D2D communication link 135 may be an example of a communication channel, such as a sidelink communication channel, between vehicles (e.g., UEs 115) . In some examples, vehicles may communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these. A vehicle may signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information relevant to a V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure, such as roadside units, or with the network via one or more network nodes (e.g., network nodes 105, base stations 140, RUs 170) using vehicle-to-network (V2N) communications, or with both.
[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 nodes 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, the 2.4 GHz band, the 60 GHz band, the 3.6 GHz band, and / or the 900 MHz band. The unlicensed spectrum may also include other frequency bands. While operating using unlicensed RF spectrum bands, devices such as the network nodes 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 node 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 node 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 node 105 may be located at diverse geographic locations. A network node 105 may include an antenna array with a set of rows and columns of antenna ports that the network node 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] The network nodes 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords) . Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) , for which multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO) , for which multiple spatial layers are transmitted to multiple devices.
[0086] 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 node 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) .
[0087] The wireless communications system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. An RLC layer may perform packet segmentation and reassembly to communicate via logical channels. A MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer also may implement error detection techniques, error correction techniques, or both to support retransmissions to improve link efficiency. In the control plane, an RRC layer may provide establishment, configuration, and maintenance of an RRC connection between a UE 115 and a network node 105 or a core network 130 supporting radio bearers for user plane data. A PHY layer may map transport channels to physical channels.
[0088] The UEs 115 and the network nodes 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly via a communication link (e.g., the communication link (s) 125, a D2D communication link 135) . HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC) ) , forward error correction (FEC) , and retransmission (e.g., automatic repeat request (ARQ) ) . HARQ may improve throughput at the MAC layer in relatively poor radio conditions (e.g., low signal-to-noise conditions) . In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific slot for data received via a previous symbol in the slot. In some other examples, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.
[0089] 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 node 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.
[0090] Some IoT devices may be A-IoT devices which may harvest energy from different ambient resources, where “ambient” may refer to a support for energy harvesting of ambient resources. For example, A-IoT devices may include circuitry that may harvest energy from an FL transmission or CW from a reader, and may use the harvested energy for transmitting a BL transmission, or backscatter signal. A backscatter signal may refer to a reflection of the CW in a same spectrum as that of the CW.Some A-IoT devices may be low power devices (e.g., a radio frequency identification (RFID) device) with limited functionality, and may function using harvested energy without use of a local power source or local power storage. Other limited functions may include limited mobility (e.g., no cell selection or reselection) and lack of HARQ processes or automatic repeat request (ARQ) processes. Additionally, or alternatively, some A-IoT devices may include some higher functionality, and may support local power storage, higher power constraints, or have a larger coverage compared to lower power devices. A-IoT devices may be read by a variety of readers. For example, a network node 105 (e.g., a base station) may function as a reader of, and directly communicate with, one or more A-IoT devices in the wireless communications system 100. Additionally, or alternatively, a UE 115 may function as a reader (e.g., a reader UE) of one or more A-IoT devices. A reader UE 115 may also act as an intermediate node under network control, and may communicate messaging between a network node 105 and one or more A-IoT devices.
[0091] The wireless communications system 100 may in some cases support coexistence between ambient links (e.g., FL or CW and BL between one or more UEs 115, network nodes 105, and A-IoT devices) and Uu links (e.g., UL and DL between network nodes 105 and UEs 115) . For example, an in-band operation of ambient IoT may involve a network node 105 configuring resources for ambient link communications and transmitting a grant to a UE reader to schedule one or more messages, including scheduling an FL message, a BL message, an UL message, or any combination thereof (e.g., with a preamble and a control message or command, FL data, BL data, etc. ) for transmission of A-IoT communications via FDD-UL, or FDD-DL resources, or both (e.g., frequency bands or spectrums) . Based on the grant, the UE 115 may also perform one or more communications with A-IoT devices using at least a subset of the configured FDD-UL resources. For example, the UE 115 may transmit a CW using a first band of the configured resources, and may receive a BL communication via a double sideband (DSB) communication including two frequency bands around the CW band.
[0092] Coexistence between Uu and A-IoT communications in FDD or TDD configurations may also introduce additional interference in the wireless communications system 100. For example, a victim device, such as a UE 115, may experience CLI from one or more aggressor devices, including other UEs 115 transmitting in UL to the network node or other UE readers transmitting a CW or a forward link (FL) to A-IoT devices in the FDD-UL resources, or network nodes 105 transmitting in DL to other UEs and or other UE readers transmitting a CW or an FL to A-IoT devices in the FDD-DL resources. In some examples, a UE 115 communicating in Uu with a network node 105 may not experience interference from one or more A-IoT devices (e.g., of a reader UE 115) due to separate coverage of A-IoT devices, and short range of IoT backscatter communications. Additionally, or alternatively, a reader UE 115 may experience interference on a backscatter link (BL) from a nearby A-IoT device. For example, communication from a UE 115 or network node 105 may introduce a small amount of interference due to a distance from a reader UE 115, but may be close enough to an A-IoT device to trigger backscatter communication interference (e.g., reflection link interference) to the reader. A reader UE 115 may in some cases rely on a network node 105 (e.g., a base station) to schedule separate resources when experiencing a relatively high level of interference. However, a reader UE 115 may lack a configuration for measuring CLI to the ambient link communications in FDD-DL / FDD-UL configurations, and so a network node 105 may be unaware of interference at one or more reader UEs 115.
[0093] As described herein, the wireless communications system 100 may support performing CLI measurements for communications involving one or more A-IoT devices. For example, a wireless communication device, such as a network node 105 (e.g., a base station, a network node) , may configure one or more devices, such as UEs 115, with CLI measurement resources, where the resources may be a subset of one or more FDD-UL resources, or FDD-DL resources, or both. The configured resources may in some cases be a subset of resources configured for ambient link communications between one or more UEs 115 or network nodes 105 and one or more A-IoT devices. Using the configured resources, a UE 115 may perform one or more CLI measurements (e.g., physical layer measurements) to record CLI from different devices. For example, the UE 115 may perform measurements to determine CLI caused by one or more UEs 115 in UL, one or more network nodes 105 in DL, or one or more interfering backscatter communications from other A-IoT devices. The UE 115 may transmit a measurement report, and the network node 105 may schedule one or more communications to reduce CLI at the UE based on CLI measurements included in the report to improve a quality of communications.
[0094] FIG. 2 shows an example of a wireless communications system 200 that supports interference measurement and reporting for ambient wireless devices in accordance with one or more aspects of the present disclosure. In some examples, the wireless communications system 200 may implement or be implemented by aspects of the wireless communications system 100. For example, the wireless communications system 200 may include one or more UEs 115, such as a UE 115-a and a UE 115-b, and one or more network nodes, including a network node 105-a, which may each be examples of UEs 115, network nodes 105, or other receiving and transmitting devices described with respect to FIG. 1. In some cases, the wireless communications system 200 may support CLI measurement for communications involving one or more ambient wireless devices, including A-IoT devices 205.
[0095] For example, the UE 115-a may act as an intermediate node under network control, and may communicate messaging between the network node 105-a and one or more A-IoT device 205. For example, the UE 115-a may share a communications link 210-a with the network node 105-a, including a UL communications link 211 and a DL communications link 212. The UE 115-a may also be configured as a reader of an A-IoT device 205-a, and may share a communications link 210-b with the A-IoT device 205-a. For example, the communications link 210-a may be an example of an ambient link, where the UE 115-a transmit a signal 213, which may be an example of a CW or an FL. The A-IoT device 205-a may also transmit a backscatter communication as a reflection of the CW from the reader or a local CW inside the A-IoT device 205-a via a BL 214. In some examples, transmission to or from A-IoT devices 205, including backscatter communications and CWs, may occur in a same UL or DL spectrum shared by one or more UEs 115. For example, ambient link communications may occur in a subset of an FDD-UL spectrum for an FDD configuration.
[0096] Devices of the wireless communications system 200 may experience CLI between devices with different resource configurations. For example, in a TDD configuration, the UE 115-a may receive a message 207-a in one or more TDD-DL resources (e.g., time slots, durations) according to a first configuration, where the message 207-a in such an example may be a DL message. The UE 115-b may also transmit a message 207-b in one or more TDD-UL resources according to a second configuration. In some cases, the network node 105-a may support full duplex communications, and may both receive and transmit at the same time (e.g., in at least partially overlapping time resources) . In full duplex, the UE 115-a (e.g., a victim device) may receive an UL transmission from the UE 115-b (e.g., an aggressor device) as CLI if an UL symbol (i.e., interfering symbol) of the UE 115-b collides with a DL symbol of the UE 115-a. For example, one or more UL time slots for the message 207-b may overlap with the one or more DL time slots for the message 207-a.
[0097] A victim UE 115 may in some cases include signaling and procedures to measure CLI from an aggressor UE 115. For example, the UE 115-a may measure CLI if a network has configured one or more CLI measurement resources in a DL BWP. CLI measurement may be configured as a layer-3 (L3) measurement (similar to radio resource management (RRM) measurement for mobility in a multi-cell scenario) . CLI measurement metrics may include sounding reference signal (SRS) reference signal receive power (SRS-RSRP) and CLI receive signal strength indicator (CSI-RSSI) measurements, where both event triggered (e.g., Event 11) and periodic reporting may be supported. In some cases, signaling used at the UE 115-a to measure CLI from the UE 115-b may be non-dedicated messaging (e.g., UE 115-b may be unaware of UE 115-a and of measurements of its UL signaling) . In some examples, measuring CLI in TDD-DL resources (or other TDD resources) may allow the network node 105-a to reschedule one or more resources to save energy and improve resource management in TDD-DL resources (or other TDD resources) .
[0098] In some cases, the wireless communications system 200 may support an FDD configuration, in which the network node 105-a may separate FDD-DL and FDD-UL resources (e.g., frequency bands, frequency ranges) to be independent, which may reduce or remove CLI. However, interference may be introduced in one or more ambient links (e.g., for an FDD-UL spectrum) of an FDD system supporting A-IoT device 205. For example, the UE 115-a (e.g., a reader UE) may communicate with the A-IoT device 205-a via the BL 214 to receive an ambient (e.g., backscatter) communication. However, the network node 105-a may be unaware of the ambient communication, and may schedule the UE 115-b to receive or transmit messages (e.g., the message 207-b via a communications link 210-c) using one or more of the same or overlapping resources (e.g., time resources, frequency resources, or both) . In some cases, the UE 115-b may be within a range (e.g., proximity) of the UE 115-a, resulting in the message 207-b also being received as CLI at the UE 115-a via a communications link 210-d between the UE 115-a and the UE 115-b. The UE 115-a may in some cases be unable to receive the message 207-b (e.g., via the BL 214) due to CLI. Unlike in TDD, the UE 115-a may lack a configuration for measuring CLI in FDD communications, leading to wasted ambient link resources and wasted A-IoT energy (e.g., of the UE 115-a and A-IoT device 205-a) .
[0099] As described herein, the wireless communications system 200 may support methods to enable a reader UE 115 to measure and report interference (e.g., CLI) from one or more proximate UEs 115 in an FDD-UL spectrum, as well as in other resources including in FDD-DL and TDD configurations. For example, the network node 105-a(e.g., a base station or gNB) may configure one or more CLI measurement resources for the UE 115-a. To configure measurement resources, the network node 105-a may transmit a message 215 to the UE 115-a that may indicate a set of resources for one or more communications links 210. In some cases, the set of resources may include FDD-UL resources, FDD-DL resources, ambient link resources, or any combination thereof. Additionally, or alternatively, the network node 105-a may transmit a control signal 220 (e.g., RRC, DCI) to indicate one or more measurement resources for an interference measurement procedure involving one or more of the communications links 210 of the UE 115-a. In some examples, the control signal may be transmitted separately from the message 215. Additionally, or alternatively, the control signal 220 (or contents of the control signal 220) may be transmitted together with the message 215 as part of a same message.
[0100] The control signal 220 may indicate one or more CLI measurement objects (e.g., via a MeasObjectCLI parameter) to be configured to the UE 115-a. Additionally, or alternatively, the control signal 220 may indicate one or more CLI measurement resources via a configuration parameter for indicating CLI measurement resources for ambient link in FDD-UL spectrum (e.g., within a CLI-ResourceConfig field) . Measurement resources may in some cases be configured for measuring SRSs, receive signal strength indicator (RSSI) values of one or more signals, or both. For example, the control signal my indicate an SRS-ResourceConfigCLI parameter or an RSSI-ResourceConfigCLI parameter for indicating SRS or RSSI resources, respectively. The CLI resources may in some cases be a subset of the set of resource configured by the message 215 (e.g., a subset of FDD-UL resources) . Additionally, or alternatively, a refBWP parameter under SRS-ResourceConfigCLI may indicate an UL BWP ID or dedicated ambient link BWP ID (e.g., AL-BWP ID) in an FDD-UL spectrum corresponding to an UL BWP configuration or ambient link BWP configuration. The control signal 220 may also indicate a startPRB parameter and an nrofPRBs, which may indicate a starting PRB or one or more RBs of an active DL BWP, respectively. Additionally, or alternatively, RSSI-ResourceConfigCLI may indicate one or more RBs of an active UL BWP or active ambient link BWP for performing one or more CLI measurements.
[0101] In some examples, for BL reception at a reader UE, such as the UE 115-a, the CLI measurement resources may be configured as a subset of ambient link resources for FL (e.g., CWs) and BL in an FDD-UL spectrum. The control signal 220 may also indicate the subset of ambient link resources if one or more ambient link resources are configured at the UE 115-a (e.g., an ambient link BWP) , or may indicate a subset of UL resources for an FDD-UL BWP if dedicated ambient link resources are not configured. In some cases, the one or more parameters described herein and included in the control signal 220 may be similar to one or more corresponding parameters for TDD configurations, but may instead be defined for FDD configurations, for ambient link communications with A-IoT devices 205, or both.
[0102] The UE 115-a may use the one or more measurement resources to perform CLI measurements. For example, the UE 115-a may utilize FDD-UL resources associated with the communications link 210-d to measure CLI interference from the UE 115-b. In some cases, such measurements may involve measuring an RSRP of one or more SRSs received via the communications link 210-d. Additionally, or alternatively, the measurements may involve measuring an RSSI of one or more signals received from the UE 115-b. In some cases, the UE 115-b may be configured with resources for both SRS and RSSI measurements. If SRS resources may not be overlapped with ambient link resources, the UE 115-a may in some cases support CLI-RSSI and refrain from performing SRS measurements. In some cases, the CLI measurement resources may be scheduled or configured to overlap with DL measurement resources in active DL BWP, or to be separate from DL measurement resources based on a UE capability to perform DL measurement concurrently with CLI measurement or separately.
[0103] The UE 115-a may transmit a measurement report 225 to indicate the one or more measurements to the network node 105-a. In some examples, CLI measurement reporting in UL spectrum may be configured to include reporting that is periodic (e.g., via RRC) or event-triggered (e.g., via a trigger DCI from the network node 105-arequesting a report) . CLI measurement may also be configured to be periodic or event-triggered. Additionally, or alternatively, a CLI measurement quality configuration may be based on L3 filtering, where an L3 filter coefficient may be configured by gNB and indicated to the UE 115-a (e.g., in the control signal 220) . In L3 filtering, an RSRP (e.g., of an SRS) or RSSI measurement may be a result of L3 level measurement, where L3 filtering may filter out one or more results. The L3 filter coefficient may also be different than another L3 filter coefficient for one or more DL CLI measurements, for example, for TDD, or if configured for FDD ambient link networks. In some examples, the network node 105-a may utilize the CLI measurements reported by the UE 115-a to reduce interference. For example, the network node 105-a may transmit a message 230 scheduling one or more uplink transmissions with the UE 115-a (e.g., via a grant in the message 230) , where the network node 105-a may perform scheduling to avoid collision between UE 115-b communications and ambient link communications at the UE 115-a. The network node 105-a may also transmit one or more messages to interfering UEs, such as the UE 115-b, to adjust scheduling.
[0104] To save resources as well as reduce UE power use resulting from CLI measurement and reporting, the network node 105-a may activate (e.g., turn on) or deactivate (e.g., turn off) one or more CLI measurement resources via indications to the UE 115-a (e.g., via a control signal 235) . The CLI resources may be deactivated in some cases in presence of little CLI at the UE 115-a, and reallocated to one or more devices to improve resource usage efficiency. The control signal 235 may in some cases be a MAC-CE, or DCI message. Additionally, or alternatively, the UE 115-a may transmit a request to activate or deactivate CLI measurement (e.g., in FDD-UL spectrum for potential interfering UEs) via a control signal 240. In some examples, the UE 115-a may transmit, via the control signal 240, a request to deactivate CLI if the UE 115-a is connected to a low quantity of A-IoT devices, or to no A-IoT devices, to save power. Additionally, or alternatively, the UE 115-a may transmit the control signal 240 indicating a request to activate CLI if the UE 115-a is connected to one or more A-IoT devices (e.g., the A-IoT device 205-a) but is unable to receive one or more BL transmissions. For example, the UE 115-a may miss one or more backscatter communications, and may transmit the control signal 240 in response.
[0105] In some examples, if CLI is a result of a UE 115 from a different cell thana cell including the UE 115-a (e.g., an inter-cell UE) , the network node 105-a may exchange ambient link resources allocated for the UE 115-a with a network node 105 of the neighboring cell. For example, the network node 105-a may transmit a message including one or more fields indicating the resources, and may perform scheduling to avoid collision with UL transmissions of the UE 115 of the other cell. In some examples, the UE 115-a may transmit a capability message 245 to indicate a capability of the UE 115-a to perform CLI measurements in FDD. Notably, the message may indicate TDD and FDD differentiation. The capability message 245 may also indicate support for CLI-RSSI or SRS-RSRP measurements, and whether the UE 115-a supports simultaneous DL reception in FDD-DL and CLI measurement in FDD-UL.
[0106] FIG. 3 shows an example of a wireless communications system 300 that supports interference measurement and reporting for ambient wireless devices in accordance with one or more aspects of the present disclosure. In some examples, the wireless communications system 300 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications system 200, or both. For example, the wireless communications system 300 may include a network node 105-b and a UE 115-c, where the UE 115-c may be configured as a reader for an A-IoT device 305-a. The UE 115-c may share a communications link 310-a with the A-IoT device 305-a and a communications link 310-b with the network node 105-b. In some cases, the wireless communications system 300 may support CLI measurement for communications involving one or more A-IoT devices 305 as described herein, including reflected interference (e.g., reflection link interference) .
[0107] For example, an aggressor UE 115, such as a UE 115-d, may be above a threshold distance from the UE 115-c, which may be a victim UE, resulting in interference (e.g., direct link interference) via a communications link 310-c from transmitting a message 307-a that may be below a threshold at the UE 115-c and may have little impact on communications. However, the UE 115-c may experience interference from one or more A-IoT devices. For example, the UE 115-c may be closer and within a range of an A-IoT device 305-b than to the UE 115-d, and in some cases may be a reader for the A-IoT device 305-b via a communications link 310-d. The UE 115-d may transmit the message 307-a to the network node 105-a via a communication link 310-e (e.g., an UL signal in FDD-UL spectrum) , which may also be received at the A-IoT device 305-b via a communications link 310-f if the A-IoT device 305-b is within a range of the UE 115-d. The reception may trigger the A-IoT device 305-b to reflect a corresponding BL transmission to the UE 115-c via the communications link 310-d, which may represent reflection link interference in one or more resources shared by the UE 115-b and the UE 115-d.
[0108] Additionally, or alternatively, BL reflections from the A-IoT device 305-b may cause interference in resources supported at the UE 115-c but not at the UE 115-d. For example, the UE 115-c may transmit an UL message 307-b, including a preamble 308-a and a control message 309-a. At a later time, the UE 115-c may transmit a signal 313-a to the A-IoT device 305-a, which may be a FL transmitted using first frequency resources or a CW transmitted using neighboring frequency resources. The UE 115-c may also receive backscatter communications from the A-IoT device 305-a via a BL 314-a using the neighboring frequency resources. At a same time or overlapping time period, the UE 115-d may transmit the message 307-a using a different set of frequency resources than the signal 313-a and the BL 314-a. The A-IoT device 305-b may receive and reflect the message 307-a in the form of a message 307-c via a BL 314-b (e.g., a backscatter communication) . However, the reflection may result in an offset in the BL causing CLI. Thus, even though the frequency resources in which the message 307-a is transmitted may be different than those in which the UE 115-c is receiving the BL 314-a, the offset may cause frequency resources in which the message 307-c is transmitted to overlap with the BL 314-a transmission.
[0109] As described herein, the UE 115-c may be configured to measure the reflection link interference triggered the UE 115-a UL message 307-a. For example, the UE 115-c may receive second information indicating a one or more second measurement resources associated with a frequency offset in relation to the first measurement resources. In some cases, the UE 115-c may receive the second information in a control signal 320 also indicating one or more first measurement resources. Additionally, or alternatively, the UE 115-c may transmit a message 350 via a signal 313-b (e.g., an FL, a CW) indicating one or more occasions for the A-IoT device 305-b to activate or deactivate based on the frequency shift and a likelihood of reflection link interference during a transmission occasion. In some cases, such techniques may be further described with respect to FIG. 4.
[0110] FIG. 4 shows an example of a resource diagram 400 that supports interference measurement and reporting for ambient wireless devices in accordance with one or more aspects of the present disclosure. In some examples, the resource diagram 400 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications system 200, the wireless communications system 300, or any combination thereof. For example, the resource diagram 400 may illustrate a resource allocation for one or more communications between the UE 115-c, the UE 115-d, the A-IoT device 305-a, and the A-IoT device 305-b to avoid reflected interference.
[0111] In some examples, for the CLI measurement in FDD-UL spectrum, the UE 115-c may be configured with CLI-SRS resources (e.g., one or more first measurement resources) together with additional CLI double sideband (DSB) RS resources (e.g., one or more second measurement resources) . For example, the UE 115-c may receive the control signal 320, which may indicate resources 405-a as well as one or more resources 405-b, one or more resources 405-c, or both. In some cases, the control signal 320 may indicate a parameter SRS-Resource configured in a parameter SRS-ResourceConfigCLI to be used to measure the CLI of UL transmissions from the UE 115-b, which may correspond to the one or more resources 405-a. Additionally, or alternatively, the control signal may indicate a frequency shift 410 with respect to the one or more resources 405-a. In some cases, the frequency shift 410 may be added to SRS-Resource in a field or parameter value to indicate the CLI-DSB-RS resources to be used to measure a BL UL signal from the A-IoT device 305-b. In some examples, the value of frequency shift 410 would may have a same value as that of a BL configuration for the A-IoT device 305-b to be received by the UE 115-c. Additionally, or alternatively, the control signal 320 may explicitly indicate one or more of the resources 405-a, 405-b, and 405-c. In some examples, the one or more resources 405-a, 405-b, and 405-c may include one or more occasions 415, which may correspond to one or more REs.
[0112] In some examples, the UE 115-c may configure the A-IoT device 305-b to be activated (e.g., on) or deactivated (e.g., off) to improve resource and power savings. For example, in the message 350, the UE 115-c may indicate one or more occasions 415 for which the A-IoT device 305-b is activated, or A-IoT “ON” occasions, for transmitting a BL signal. During A-IoT ON occasions, the CLI-RSRP on the CLI-DSB-RS resources, or resources 405-b and 405-c, in FDD-UL may include the interference of BL triggered by the UL of aggressor UE. The message 350 may also indicate one or more occasions 415 for which the A-IoT device is deactivated, or A-IoT “OFF” occasions. During the A-IoT OFF occasions, the CLI-RSRP on the CLI-DSB-RS resources in FDD-UL may lack reflection link interference as the A-IoT device may not be activated and may be unable to reflect UL or other transmissions. In some examples, the CLI-DSB-RS resources in different A-IoT ON or OFF occasions may be separately filtered by using configured L3-filtering. Notably, the UE 115-a may configure ON / OFF occasions based on when the UE 115-a may communicate with the A-IoT device 305-b, and thus may save resources and energy during occasions where the A-IoT device 305-b is turned off and not communicating.
[0113] In some examples, additional parameters may be defined or updated to support resources for CLI measurements and reflection link interference measurements described with respect to FIGs. 2 and 3. For example, the control signal 320 may indicate one or more of SRS-ResourceId, RSSI-ResourceId, measResultCLI, FilterConfigCLI, CLI-PeriodicalReportConfig, and CLI-EventTriggerConfig parameters. Additionally, or alternatively, the UE 115-c may report CSI related to the resources 405-a, 405-b, and 405-c separately or within a same measurement report. Further, the UE 115-c may measure CLI-RSRP measurements including RSRP on the CLI-SRS (e.g., resources 405-a) and RSRP on the CLI-DSB-RS resources (e.g., resources 405-b and 405-c) .
[0114] Although the methods described herein may in some cases be described with reference to FDD-UL communication resources, or FDD-UL BWP configured for a UE, such methods may be utilized for any combination of resources. For example, one or more measurement resources (e.g., 405-a, 405-b, or 405-c) may include resources for ambient links in FDD-UL, for ambient links in FDD-DL, or for ambient links in TDD communications. Notably, the UE 115-c may receive measurement resources for ambient links in FDD-UL to measure CLI from UL signaling in Uu links (e.g., UE 115-b transmission in UL) to A-IoT ambient links (e.g., A-IoT UL or BL) at UE 115-a. Resources may also be indicated for ambient links in FDD-DL to measure CLI from DL signaling in Uu links (e.g., DL transmissions from the network node 105-a) . Resources may also be indicated for ambient links in TDD to measure CLI in TDD from Uu links (e.g., in UL) or other links. Resources in FDD-UL, FDD-DL, and TDD may also be indicated for measuring CLI between two ambient links, such as for measuring reflection link interference, or measuring CLI caused by other CW or FL or BL communications. The methods described herein with respect to FIGs. 1–5 may also be performed by additional devices (in addition to UEs 115, network nodes 105, and A-IoT devices) to measure additional types of interference.
[0115] FIG. 5 shows an example of a process flow 500 that supports interference measurement and reporting for ambient wireless devices in accordance with one or more aspects of the present disclosure. In some examples, the process flow 500 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications system 200, the wireless communications system 300, the resource diagram 400, or any combination thereof. For example, the process flow 500 may include one or more UEs 115, including a UE-e and a UE-f, one or more network nodes, including a network node 105-c, and one or more A-IoT devices (e.g., A-IoT devices) , including A-IoT devices 505-a and 505-b. In some cases, the UE 115-e may be configured as a reader for and may share an ambient link with the A-IoT device 505-a, the A-IoT device 505-b, or both.
[0116] In the following description of the process flow 500, the operations may be performed (such as reported or provided) in a different order than the order shown, or the operations performed by the example devices may be performed in different orders or at different times. Some operations also may be omitted from the process flow 500, or other operations may be added to the process flow 500. Further, although some operations or signaling may be shown to occur at different times for discussion purposes, these operations may actually occur at the same time or at least partially concurrently.
[0117] At 510, the UE 115-e (e.g., a first wireless communication device) may optionally transmit, and the network node 105-c (e.g., a second wireless communication device, a fourth wireless communication device) may optionally obtain (e.g., receive directly or via another component or device) a capability message. In some examples, the capability message may indicate a capability of the UE 115-e to perform CLI measurement using a set of resources.
[0118] At 515, the UE 115-e may receive, and the network node 105-c may output (e.g., transmit directly or via another component or device) a message that indicates a set of resources for the UE 115-e. In some cases, the set of resources may be configured for a first communications link between the UE 115-e and a second wireless communication device, or for a second communications link between the UE 115-e and a third wireless communication device, or both. For example, the first communications link may be between the UE 115-e and the network node 105-c (e.g., the second wireless communication device) and the second communications link may be between the UE 115-e and the A-IoT device 505-a (e.g., the third wireless communication device) . Additionally, or alternatively, the first communications link may be between the UE 115-e and the UE 115-f (e.g., second communications device) . By way of another example, the first communications link may instead be between the UE 115-e and a first ambient wireless device, such as the A-IoT device 505-a, where the A-IoT device 505-b may be a second ambient wireless device connected with the UE 115-e.
[0119] In some examples, the message or resources may be based on the capability message at transmitted at 510.

[0124] At 535, the UE 115-e may optionally transmit a second message indicating one or more first durations associated with an ambient device being activated, or one or more second durations associated with an ambient wireless device being deactivated, or a combination thereof. For example, may transmit the second message to the A-IoT device 505-b to configure one or more on or off occasions to avoid reflected interference from the A-IoT device 505-b.
[0125] At 540, the UE 115-e may perform, as part of the CLI measurement procedure, one or more CLI measurements via the one or more measurement resources. For example, the UE 115-e may measure CLI in a link with the UE 115-f (FDD-UL resources) , may measure CLI in a link with the network node 105-c (FDD-DL resources) , or may measure reflection link interference in a link with the A-IoT device 505-b. In some cases, the UE 115-e may experience CLI from one or more of the UE 115-f, the network node 105-c, the A-IoT device 505-b, or any combination thereof at an ambient link with the A-IoT device 505-a. In some examples, the one or more CLI measurements may be performed based on the second control signal received at 525. Additionally, or alternatively, the one or more CLI measurements may be based on the filter coefficient.
[0126] In some examples, the one or more measurement resources and the one or more CLI measurements may be associated with one or more RSRP measurements, or with one or more RSSI measurements, or a combination thereof.
[0127] At 545, the UE 115-e may transmit, and the network node 105-c may obtain, a measurement report indicating the one or more CLI measurements.
[0128] At 550, the network node 105-c may optionally communicate a third message with a fifth wireless communication device indicating the one or more measurement resources for the CLI measurement procedure.

[0267] As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of” or “one or more of” ) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C) . Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on. ”
[0268] As used herein, including in the claims, the article “a” before a noun is open-ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns.

For example, if a claim recites “a component” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “a component” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent reference to a component introduced with the article “a” using the terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components, ” and referring to “the component” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ” Similarly, subsequent reference to a component introduced as “one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ”
[0269] The term “determine” or “determining” encompasses a variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database, or another data structure) , ascertaining, and the like. Also, “determining” can include receiving (e.g., receiving information) , accessing (e.g., accessing data stored in memory) , and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.
[0270] In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label or other subsequent reference label.
[0271] 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.
[0272] The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure.
