[0001] This patent application claims priority from Greek Patent Application No. 20220100044, entitled "RADIO FREQUENCY SENSING WITH CHANNEL IMPULSE RESPONSE", filed on January 18, 2022, which is assigned to the assignee of this application. The disclosure of the prior application is considered a part of this patent application and is incorporated herein by reference.

[0002]

[0002] Aspects of the present disclosure generally relate to wireless communication and pertain to techniques and apparatus for radio frequency sensing using channel impulse response.

Background Art

[0003]

[0003] Wireless communication systems are widely deployed to provide a variety of telecommunication services such as telephone, video, data, messaging, and broadcast. Typical wireless communication systems can utilize multiple access technologies that enable communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of extensions to the Universal Mobile Telecommunications System (UMTS) mobile standard published by the Third Generation Partnership Project (3GPP). Other technologies may include ultra-wideband (UWB) technology.

[0004]

[0004] A wireless network may include one or more base stations that support communication relating to a single user equipment (UE) or multiple UEs. The UE can communicate with the base station via downlink and uplink communications. "Downlink" (or "DL") refers to the communication link from the base station to the UE, and "uplink" (or "UL") refers to the communication link from the UE to the base station.

[0005]

[0005] The above-mentioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different UEs to communicate at the city, national, regional, and / or global scales. New Radio (NR), sometimes referred to as 5G, is a set of extensions to the LTE mobile standard published by 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, enhancing service, utilizing new spectra, using orthogonal frequency division multiplexing (OFDM) with cyclic prefixes (CP) on the downlink, and CP-OFDM and / or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM, DFT-s-OFDM) on the uplink, as well as by better integrating with other open standards that support beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to grow, further improvements in LTE, NR, and other radio access technologies remain valuable. [Overview of the Initiative]

DETAILED DESCRIPTION OF THE INVENTION

[0018]

[0025] Various aspects of the present present present are more fully described below with reference to the accompanying drawings. However, the disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. It is to be understood by those skilled in the art that the scope of the disclosure, whether implemented in isolation from any other aspect of the disclosure or in combination with any other aspect of the disclosure, is intended to encompass any aspect of the disclosure disclosed herein. For example, any number of aspects described herein may be used to implement an apparatus or perform a method. Note that the scope of the disclosure is intended to encompass apparatus or methods practiced using other structures, functionality, or structures and functionality in addition to or other than the various aspects of the disclosure described herein. It is to be understood that any aspect of the disclosure disclosed herein can be embodied by one or more elements of the claims.

[0019]

[0026] Next, some aspects of a telecommunications system are presented while referring to various devices and techniques. These devices and techniques are described in the context of embodiments for implementing the following inventions and are shown in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or as software depends on the specific application and the design constraints imposed on the overall system.

[0020]

[0027] Aspects may be described herein using terms generally associated with 5G or New Radio (NR) radio access technology (RAT), but aspects of the disclosure can be applied to other RATs such as 3G RAT, 4G RAT, and / or RATs after 5G (e.g., 6G).

[0021]

[0028] UWB technology allows for the transmission of signals with wide bandwidths (e.g., >500 MHz). The signal energy can be transmitted without interference from narrowband carriers within the same frequency band. UWB can be used for low-energy, short-range applications, such as ranging. UWB is currently divided into channels 1-15, spanning frequencies from approximately 3.5 GHz to 4.5 GHz and 6.5 GHz to 10 GHz.

[0022]

[0029] Figure 1 shows an example of a wireless network 100 as described herein. The wireless network 100 may be or may include elements of a 5G (e.g., NR) network, a 4G (e.g., Long-Term Evolution (LTE)) network, a wide area network (WAN) access point (AP), a personal area network (PAN) access point and device, or a UWB device (e.g., a UWB anchor, a UWB tag), among other examples. The wireless network 100 may include one or more network entities, for example, base stations, APs, or UWB devices 110 (indicated as BS, AP, or UWB device 110a, picoBS, AP, or UWB device 110b, femtoBS, AP, or UWB device 110c, and relay BS, AP, or UWB device 110d). The wireless network 100 may also include one user equipment (UE) 120 or multiple UEs 120 (represented as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e). A base station, AP, or UWB device 110 is a network entity that communicates with the UEs 120. A base station (sometimes called a BS) may include, for example, an NR base station, an LTE base station, a node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), and / or a transmit / receive point (TRP). Each base station, AP, or UWB device 110 can provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” may, depending on the context in which the term is used, refer to the coverage area of ​​a base station, AP, or UWB device 110 and / or the base station subsystems providing service to this coverage area.

[0023]

[0030] In some embodiments, the terms “base station” or “network entity” may refer to an aggregated base station, a non-aggregated base station, an integrated access and backhaul (IAB) node, a relay node, and / or one or more components thereof. For example, in some embodiments, “base station” or “network entity” may refer to a central unit (CU), a distributed unit (DU), a radio unit (RU), a near-real-time (Near-RT) RAN intelligent controller (RIC), or a non-real-time (Non-RT) RIC, or a combination thereof. In some embodiments, the terms “base station” or “network entity” may refer to a single device configured to perform one or more functions, such as the functions described herein with respect to a base station. In some embodiments, the terms “base station” or “network entity” may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of several different devices (which may be located in the same or different geographical locations) may be configured to perform at least a portion of a function, or to replicate the performance of at least a portion of a function, and the terms “base station” or “network entity” may refer to any one or more of those different devices. In some embodiments, the terms “base station” or “network entity” may refer to one or more virtual base stations and / or one or more virtual base station functions. For example, in some embodiments, two or more base station functions may be instantiated on a single device. In some embodiments, the terms “base station” or “network entity” may refer to one of the base station functions and not another. Thus, a single device may contain two or more base stations. WAN access points, PAN access points, UWB devices (e.g., UWB anchors, UWB tags, or other forms of UWB-enabled devices), and UWB access points may also be referred to as “network entities.”The network entity may include the components described with respect to the base station, AP, or UWB device 110.

[0024]

[0031] A base station, AP, or UWB device 110 can provide communication coverage for macrocells, picocells, femtocells, and / or other types of cells. A macrocell can cover a relatively large geographical area (e.g., a radius of several kilometers) and may enable unrestricted access by UEs 120 subscribing to the service. A picocell can cover a relatively small geographical area and may enable unrestricted access by UEs 120 subscribing to the service. A femtocell can cover a relatively small geographical area (e.g., a home) and may enable limited access by UEs 120 associated with a femtocell (e.g., UEs 120 within a closed subscriber group, CSG). A base station for a macrocell is sometimes called a macro base station. A base station for a picocell is sometimes called a pico base station. A base station for a femtocell is sometimes called a femto base station or home base station. In the embodiment shown in Figure 1, the BS, AP, or UWB device 110a may be a macro base station, AP, or UWB device for macrocell 102a, the BS, AP, or UWB device 110b may be a pico base station, AP, or UWB device for picocell 102b, and the BS, AP, or UWB device 110c may be a femto base station, AP, or UWB device for femtocell 102c. A base station may support one or more (e.g., three) cells. A network entity may be a macro base station, a pico base station, or a femto base station.

[0025]

[0032] In some embodiments, cells may not necessarily be fixed, and the geographical area of ​​a cell may move according to the location of a mobile base station (e.g., a mobile base station). In some embodiments, base stations, APs, or UWB devices 110 may interconnect with each other and / or with one or more other base stations, APs, or UWB devices 110 or network entities (not shown) within the wireless network 100, through various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.

[0026]

[0033] The wireless network 100 may include one or more relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a network entity or UE 120) and send data transmissions to a downstream station (e.g., a UE 120 or a network entity). A relay station may also be a UE 120 that can relay transmissions to other UE 120s. In the embodiment shown in Figure 1, a BS, AP, or UWB device 110d (e.g., a relay base station) can communicate with a BS, AP, or UWB device 110a (e.g., a macro base station, AP, or UWB device) and a UE 120d to facilitate communication between the BS, AP, or UWB device and the UE 120d. A base station that relays communications may be called a relay station, relay base station, or repeater.

[0027]

[0034] The wireless network 100 may be a heterogeneous network including different types of base stations, such as macro base stations, pico base stations, femto base stations, and relay base stations. These different types of base stations, different types of APs, and different types of UWB devices may have different transmit power levels, different coverage areas, and / or different effects on interference within the wireless network 100. For example, macro base stations, APs, or UWB devices may have high transmit power levels (e.g., 5 to 40 watts), while pico base stations, APs, or UWB devices, femto base stations, APs, or UWB devices, and relay base stations, APs, or UWB devices may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0028]

[0035] The network controller 130 may be coupled to a set of network nodes or communicate with a set of network entities and may provide coordination and control for these network entities. The network controller 130 can communicate with network entities via backhaul communication links. Network entities may communicate with each other directly or indirectly via wireless or wired backhaul communication links.

[0029]

[0036] UE120 may be distributed across the entire wireless network 100, and each UE120 may be fixed or mobile. UE120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE120 can be cellular telephones (e.g., smartphones), personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, laptop computers, cordless phones, wireless local loop (WLL) stations, tablets, cameras, gaming devices, netbooks, smartbooks, ultrabooks, medical devices, biometric devices, wearable devices (e.g., smartwatches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart rings or smart bracelets)), entertainment devices (e.g., music devices, video devices, and / or satellite radios), vehicle components or sensors, smart meters / sensors, industrial manufacturing equipment, global positioning system devices, and / or any other suitable devices configured to communicate via a wireless medium. The UE 120 may be capable of UWB communication.

[0030]

[0037] Some UE120s may be considered machine-type communication (MTC) UEs, or evolved or enhanced machine-type communication (eMTC) UEs. Examples of MTC UEs and / or eMTC UEs include robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with base stations, other devices (e.g., remote devices), or any other entities. Some UE120s may be considered Internet-of-Things (IoT) devices and / or implemented as NB-IoT (narrowband IoT) devices. Some UE120s may be considered customer premises equipment. A UE120 may be contained within a housing that accommodates its components, such as processor components and / or memory components. In some embodiments, the processor components and memory components may be coupled to each other. For example, processor components (e.g., one or more processors) and memory components (e.g., memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0031]

[0038] In general, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 may support a specific RAT and can operate on one or more frequencies. RAT is sometimes called a wireless technology, air interface, etc. Frequencies are sometimes called carriers, frequency channels, etc. To avoid interference between wireless networks of different RATs, each frequency may support a single RAT in a given geographical area. In some cases, NR networks or 5G RAT networks can be deployed. In some cases, WAN, PAN, or UWB networks can be deployed.

[0032]

[0039] In some embodiments, two or more UE120s (for example, shown as UE120a and UE120e) can communicate directly using one or more sidelink channels (for example, without using network entities as a medium for communication with each other). For example, the UE120s may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such embodiments, the UE120s can perform scheduling operations, resource selection operations, and / or other operations described elsewhere in this specification as being performed by base stations, APs, or UWB devices 110.

[0033]

[0040] Devices in wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various classes, bands, channels, etc., depending on the frequency or wavelength. For example, devices in wireless network 100 may communicate using one or more operating bands. The UWB frequency bandwidth may be greater than 500 MHz. In 5G NR, two initial operating bands are identified as frequency range designations FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 52.6 GHz). Although a portion of FR1 is higher than 6 GHz, it should be understood that FR1 is often referred to (interchangeably) as the "sub-6 GHz" band in various documents and papers. A similar nomenclature issue may arise with respect to FR2, which is often referred to (interchangeably) as the "millimeter wave" band in documents and papers, even though it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) which is identified by the International Telecommunication Union (ITU) as the "millimeter wave" band.

[0034]

[0041] The frequencies between FR1 and FR2 are often referred to as intermediate band frequencies. Recent 5G NR research identifies the operating band for these intermediate band frequencies as frequency range designation FR3 (7.125 GHz to 24.25 GHz). The frequency bands falling within FR3 may inherit the FR1 and / or FR2 characteristics, and thus, in effect, the features of FR1 and / or FR2 can be extended to the intermediate band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0035]

[0042] With the above examples in mind, unless otherwise specified, terms such as “sub-6GHz” may, when used herein, broadly refer to frequencies that may be below 6GHz, within FR1, or include intermediate band frequencies. Furthermore, unless otherwise specified, terms such as “millimeter wave” may, when used herein, broadly refer to frequencies that may include intermediate band frequencies, within FR2, FR4, FR4-a or FR4-1, and / or FR5, or within the EHF band. The frequencies included within these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are intended to be applicable to those modified frequency ranges.

[0036]

[0043] In some embodiments, the responding device (e.g., UE 120, network entity) may include a communications manager 140 or 150. As will be described in more detail elsewhere in this specification, the communications manager 140 or 150 may receive a signal from the initiating device, estimate from that signal a channel impulse response (CIR) representing signal reflections from one or more objects as multiple taps, and select one or more taps from the multiple taps, at least in part on a configuration for providing a consistent CIR report. The communications manager 140 or 150 may send a CIR report to the initiating device indicating one or more taps.

[0037]

[0044] In some embodiments, the initiating device (e.g., UE 120, network entity) may include a communications manager 140 or 150. As described in more detail elsewhere in this specification, the communications manager 140 or 150 may transmit a signal containing multiple packets and receive a CIR report from a responding device for each of the multiple packets. The communications manager 140 or 150 may align the CIR reports across multiple packets by using one or more taps in the CIR report for each packet to identify a target object, the location of the target object, or the movement of the target object. The communications manager 140 or 150 may take action based at least in part on the target object, the location of the target object, or the movement of the target object. In addition or alternatively, the communications manager 140 or 150 may perform one or more other actions described herein.

[0038]

[0045] As shown above, Figure 1 is provided as an example. Other embodiments may differ from those described with respect to Figure 1.

[0039]

[0046] Figure 2 shows an embodiment 200 of a network entity (e.g., a base station, AP, or UWB device 110) communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station, AP, or UWB device 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≧1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≧1). A WAN access point may also include components as described for the base station, AP, or UWB device 110 and may operate in accordance with an Institute of Electrical Engineers (IEEE) standard (e.g., IEEE 802).

[0040]

[0047] In a base station, AP, or UWB device 110, the transmit processor 220 can receive data from a data source 212 that is intended for a UE 120 (or a set of UE 120s). The transmit processor 220 may select one or more modulation and coding schemes (MCSs) for the UE 120, at least in part, based on one or more channel quality indicators (CQIs) received from the UE 120. The base station, AP, or UWB device 110 can process (e.g., encode and modulate) data relating to the UE 120, at least in part, based on the MCS(s) selected for the UE 120, and can provide data symbols relating to the UE 120. The transmit processor 220 can process system information and control information (e.g., CQI requests, authorizations, and / or upper-layer signaling) (e.g., relating to semi-static resource partitioning information (SRPI)), and can provide overhead symbols and control symbols. The transmit processor 220 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may, where applicable, perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) designated as modems 232a to 232t.For example, each output symbol stream may be provided to a modulator component (indicated as MOD) of modem 232. Each modem 232 may use its respective modulator component to process its respective output symbol stream for the purpose of acquiring an output sample stream (e.g., for OFDM). Each modem 232 may further use its respective modulator component to process the output sample stream for the purpose of acquiring a downlink signal (e.g., convert to analog, amplify, filter, and / or upconvert). Modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) indicated as antennas 234a to 234t.

[0041]

[0048] In UE120, a set of antennas 252 (indicated as antennas 252a to 252r) can receive downlink signals from base stations, APs or UWB devices 110 and / or other base stations, APs or UWB devices 110, and can provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) indicated as modems 254a to 254r. For example, each received signal may be provided to a demodulator component of a modem 254 (indicated as DEMOD). Each modem 254 may use its respective demodulator component to adjust the received signal for the purpose of acquiring an input sample (e.g., filtering, amplification, downconverting, and / or digitizing). Each modem 254 may also use its demodulator component to further process the input sample (e.g., for OFDM) for the purpose of acquiring a received symbol. A MIMO detector 256 may acquire a received symbol from a modem 254, perform MIMO detection on the received symbol where applicable, and provide the detected symbol. The receiving processor 258 can process the detected symbols (e.g., demodulate and decode), provide the decoded data to the UE 120 to the data sink 260, and provide the decoded control and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may, among other examples, determine the reference signal received power (RSRP) parameter, the received signal strength indicator (RSSI) parameter, the reference signal received quality (RSRQ) parameter, and / or the CQI parameter. In some embodiments, one or more components of the UE 120 may be contained within the housing 284.

[0042]

[0049] The network controller 130 may include a communication unit 294, a controller / processor 290, and memory 292. The network controller 130 may include, for example, one or more devices in the core network. The network controller 130 may communicate with network entities via the communication unit 294.

[0043]

[0050] One or more antennas (for example, antennas 234a-234t and / or antennas 252a-252r) may include, or be contained within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, among other examples. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include one or more antenna elements (in a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and / or one or more antenna elements coupled to one or more transmitting and / or receiving components, such as one or more components in Figure 2.

[0044]

[0051] On the uplink, in the UE120, the transmit processor 264 can receive and process data from the data source 262 and control information (for reporting, including RSRP, RSSI, RSRQ, and / or CQI) from the controller / processor 280. The transmit processor 264 can generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may, where applicable, be precoded by the TX MIMO processor 266, further processed by the modem 254 (for DFT-s-OFDM or CP-OFDM), and transmitted to the network entity. In some embodiments, the modem 254 of the UE120 may include a modulator and a demodulator. In some embodiments, the UE120 includes a transceiver. The transceiver may include any combination of antennas 252, modems 254, MIMO detectors 256, a receive processor 258, a transmit processor 264, and / or the TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform any of the methods described herein (for example, with reference to Figures 3 to 9).

[0045]

[0052] In a network entity (e.g., a base station, AP, or UWB device 110), uplink signals from UE 120 and / or other UEs are received by antenna 234, processed by modem 232 (e.g., a demodulator component of modem 232, indicated as DEMOD), detected by MIMO detector 236 where applicable, and further processed by a receiving processor 238 to obtain decoded data and control information transmitted by UE 120. The receiving processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. The network entity may also include a communication unit 244, which can communicate with the network controller 130 via the communication unit 244. The network entity may also include a scheduler 246 for scheduling one or more UE 120 for downlink and / or uplink communication. In some embodiments, the modem 232 of the network entity may include a modulator and a demodulator. In some embodiments, the network entity includes a transceiver. The transceiver may include any combination of an antenna(s) 234, a modem(s) 232, a MIMO detector 236, a receiving processor 238, a transmitting processor 220, and / or a TX MIMO processor 230. The transceiver may be used by a processor (e.g., a controller / processor 240) and memory 242 to perform any aspect of the methods described herein (for example, with reference to Figures 3 to 9).

[0046]

[0053] The controller / processor of the network entity (e.g., the controller / processor 240 of the base station, AP, or UWB device 110), the controller / processor 280 of the UE 120, and / or any other component(s) in Figure 2 may perform one or more techniques associated with RF sensing, as will be described in more detail elsewhere in this specification. For example, the controller / processor 240 of the base station, AP, or UWB device 110, the controller / processor 280 of the UE 120, and / or any other component(s) in Figure 2 may perform or direct the operation of, for example, process 600 in Figure 6, process 700 in Figure 7, and / or other processes as described herein. Memories 242 and 282 may store data and program code for the network entity and the UE 120, respectively. In some embodiments, memories 242 and / or 282 may include a non-temporary computer-readable medium for storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when one or more instructions are executed by one or more processors of the network entity and / or UE120 (e.g., directly or after compilation, translation, and / or interpretation), one or more processors, UE120, and / or the network entity can be instructed to perform or direct the operation of, for example, process 600 in Figure 6, process 700 in Figure 7, and / or other processes described herein. In some embodiments, executing an instruction may include, among other examples, executing the instruction, translating the instruction, compiling the instruction, and / or interpreting the instruction.

[0047]

In some embodiments, the means for the response device to perform the operations described herein may include, for example, one or more of the following: a communications manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receiving processor 258, a transmitting processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0048]

In some embodiments, the means for causing the initiating device to perform the operations described herein may include, for example, one or more of the following: communications manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.

For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0050]

[0057] As shown above, Figure 2 is provided as an example. Other embodiments may differ from those described with respect to Figure 2.

[0051]

[0058] Figures 3 and 4 show an example of RF sensing 300 according to this disclosure.

[0052]

[0059] RF sensing may be used to identify a target object 310. Example 300 illustrates an example of bistatic unidirectional sensing. An initiating device 320 (e.g., UE 120, a network entity) may transmit a signal reflected from the target object 310 (e.g., a user, another person, a body part, an animal, a robot) and other surfaces. A responding device 330 (e.g., UE 120, a network entity) may receive the direct signal and the reflected signal. The responding device 330 may estimate the CIR from the signal. While the direct signal may be received, the RF sensing may focus on the reflected signal and may distinguish the reflected signal from the direct signal by intensity, time, or other information. The CIR can represent or characterize signal reflections from one or more objects as one or more taps. The taps may indicate the signal intensity of the reflected signal received at different points in time (e.g., t0, t1, etc.). As shown in Figure 3 and reference no. 335, the response device 330 may generate a CIR report 336 (e.g., a CIR measurement report) that includes one or more of the taps 338. As shown in Figure 4 and reference no. 340, the response device 330 may send the CIR report 336 to the initiating device 320. As shown in reference no. 345, the initiating device 320 can identify the target object 310 from the taps 338 of the CIR report 336.

[0053]

[0060] RF sensing has different requirements than wireless communication. According to IEEE standard 802.15, UWB data communication does not depend on channel consistency from one packet to the next. However, in UWB ranging, if channel measurements from one packet to the next are inconsistent, the CIR report 336 for multiple packets may appear as random taps. As a result, the CIR report 336 may not be useful for RF sensing applications. RF sensing infers environmental changes by measuring changes in the wireless channel. If consistent CIR measurements and reports are not met, a wireless device may conclude that the measured and reported changes in the wireless channel are due to changes in the physical environment and not the wireless device itself.

[0054]

[0061] As shown above, Figures 3 and 4 are provided as examples. Other embodiments may differ from those described with respect to Figures 3 and 4.

[0055]

[0062] Figure 5 shows an example of how to align CIR reports 500 as described in this disclosure.

[0056]

[0063] According to various embodiments described herein, the response device 330 may select one or more reference taps from each of several packets that the initiating device 320 can use to match the CIR report 336. A tap may refer to an energy rise in the channel impulse response at a point in time or opportunity that may indicate a direct or reflected signal. A tap may appear for detected energy that is not part of the direct or reflected signal and may be due to interference energy or other noise. Matching the CIR report may include matching the CIR report at least temporally. This may include, for example, identifying taps in the first CIR report (e.g., satisfying a threshold) that occur at the same time or opportunity as a tap in the second CIR report, such that a tap for a direct or reflected signal in the first CIR report matches a tap for the same direct or reflected signal in the second CIR report. By matching the CIR report, the initiating device 320 can better identify the target object 310, the movement of the target object 310, or other characteristics of the target object 310. The initiation device 320 can take more appropriate action using better identification of the target object 310, thereby saving processing and signaling resources. For example, among other RF sensing applications, the initiation device can better detect the location of body parts of a user (e.g., a human, robot, or autonomous device), detect user activity (e.g., human or animal gestures or breathing patterns), identify objects near a user, or detect the movement of objects around a user.

[0057]

[0064] As shown in Example 300 in Figures 3 and 4, the initiating device 320 may transmit a signal, and the responding device 330 may receive reflections of the signal from one or more objects, including the target object 310. Example 500 in Figure 5 shows the matching of CIR feedback for more accurate RF sensing, starting with the generation of CIR feedback by the responding device 330.

[0058]

[0065] In some embodiments, the responding device 330 may be configured (e.g., by the initiating device 320, by another device, or at manufacture) to select one or more reference points to be provided for the CIR report 336. The reference points may be the earliest tap, the strongest tap 502, the centroid of a tap, the packet detection time, or any other designated tap or point in time. The responding device 330 may use configurations to provide a consistent CIR report. A consistent CIR report may be a set of CIR reports that work together to provide accurate RF sensing information about an object. A consistent CIR report may include a CIR report with information (e.g., taps, reference points) that the initiating device can use to temporally align the CIR report to match reflected signals to an object over time in order to identify the object when it is in motion. The configuration may specify which taps to select for the CIR report, including how many taps to select before or after a reference point to collect the taps, or for how long to select before or after a reference point.

[0059]

[0066] In Example 500, as shown by reference no. 505, the responding device 330 may select the strongest tap 502 from among the taps relating to the transmitted signal packet. In some embodiments, the responding device 330 may select n strongest taps, where n is a configurable parameter that may be specified and adjusted at least in part on sensing conditions.

[0060]

[0067] In some embodiments, as indicated by reference no. 510, the response device 330 may select a tap that satisfies a tap threshold 512 (e.g., minimum RSRP). This may be done in addition to selecting the strongest tap 502. By specifying the selection of stronger taps, non-critical taps can be eliminated, thereby reducing signaling overhead.

[0061]

[0068] In some embodiments, the response device 330 may select all taps between the earliest tap that satisfies the threshold 512 and the latest tap that satisfies the threshold 512. This allows for the provision of additional context or additional reference taps for alignment for some reflected signals without significantly increasing signaling overhead.

[0062]

[0069] In some embodiments, as shown by reference no. 515, the response device 330 may select a tap that falls within a time window 516 of a specified duration. The duration is the preceding duration value (t) of the reference tap (t0) (e.g., the strongest tap 502). lead ) and the lagging duration value t lag The duration can be specified by (for example, in the settings). The duration may be a fixed length. In some embodiments, the duration may be large enough to capture important CIR taps expected for the RF sensing application, and the duration may be adjusted depending on the RF sensing conditions or RF application. For example, if the line of sight between the initiating device 320 and the responding device 330 is not obstructed, the strongest tap 502 may be close to the first tap. Thus, the window may be determined to be asymmetrical with respect to the strongest tap 502. The settings can specify how many taps to report before or after a reference point such as the strongest tap 502. In short, as shown by reference no. 520, the responding device 330 can generate a CIR report 336 using settings for a consistent CIR report to select the taps to include in the CIR report 336, as described with respect to Figure 5.

[0063]

[0070] In some embodiments, the CIR feedback sampling rate may vary to identify and select taps. For example, the feedback sampling rate is a multiple of the UWB chip rate (e.g., 499.2 MHz), and may be, for example, the chip rate, twice the chip rate, or four times the chip rate.

[0064]

[0071] In some embodiments, depending on the range under coverage, the response device 330 may determine the number of taps to use based at least in part on the delay spread to cover the area divided by the chip rate (and scaling factor). For example, 10-meter (m) pass coverage may use 17 taps at a chip rate of 2 nanoseconds (ns), or 34 taps at twice the chip rate, 1 ns.

[0065]

[0072] In some embodiments, the setting may specify the format for CIR values ​​in the CIR report. The setting may specify that the CIR report should include amplitude and phase (e.g., pole domain) for each tap or other CIR value. The setting may specify that the CIR report should include in-phase and orthogonal (IQ) values ​​or other CIR values ​​for each tap.

[0066]

[0073] In some embodiments, CIR values ​​may be compressed for CIR reporting. This may include normalizing tap amplitudes to the amplitude of the strongest tap. The CIR report may include a normalization factor. The CIR report may include differential IQ values, which may include variations in IQ values ​​across packets. In some embodiments, the size of the CIR report may be based at least in part on the amount of bits assigned to each tap in the CIR report, the sensing range under coverage, and the CIR sampling rate.

[0067]

[0074] As shown in reference number 525, the responding device 330 may send a CIR report to the initiating device 320. The responding device 330 may send multiple CIR reports relating to multiple packets, each CIR report relating to one or more packets. As shown by reference number 530, the initiating device 320 may coordinate the CIR reports to identify at least the target object 310. The initiating device 320 may coordinate the CIR reports to identify other objects. By associating taps in the CIR reports with the target object 310, the target object 310's location, the target object 310's movement, or other characteristics of the target object 310 (either alone or in relation to other objects), the initiating device 320 may identify the target object 310, its location, its movement, or other characteristics of the target object 310 (either alone or in relation to other objects). Coordinating the CIR reports helps the initiating device 320 determine which taps in each CIR report correspond to other taps in other CIR reports.

[0068]

[0075] For example, initiating device 320 may receive four CIR reports for four packets, among other CIR reports. Example 500 shows reports 532, 534, 536, and 538. Without a suitable reference point for each report, a tap in one report would not be associated with a tap in another report, resulting in inconsistency between CIR reports. RF sensing would be limited. However, in some embodiments, each report may have a reference point 540. In Example 500, the reference point is, for example, the strongest tap 502 in each CIR. While the reports in Example 500 show multiple taps, in some embodiments, reports may include fewer, stronger taps, or taps between specified taps.

[0069]

[0076] The initiating device 320 can use the reference point 540 to align reports and identify signals corresponding to the same object across reports / packets. Using signals that match the object, the initiating device 320 can identify the object, the object's location, the object's movement, other characteristics of a particular object (including the target object 310), or characteristics of the environment surrounding the object.

[0070]

[0077] As shown by reference no. 545, the initiating device 320 can perform actions based at least in part on the target object 310, the location of the target object 310, the movement of the target object 310, or other characteristics of the target object 310. Such actions may include sending communications to the target object 310, sending communications to another device that uses an application related to the target object 310, using information about the target object 310 in an application (e.g., a sensing application, a health application, a medical application, a gaming application, an industrial application), sending notifications about the target object 310, initiating movement caused by the target object 310, and so on.

[0071]

[0078] In Example 500, the initiating device 320 can transmit a signal to the responding device 330 and collect the reflected signal. However, in other scenarios, the initiating device 320 and the responding device 330 may be in the same location or may be the same device.

[0072]

[0079] In some embodiments, the response device 330 may have multiple antennas, each of which may receive signal reflections. The response device 330 may generate a CIR report for each antenna. The response device 330 may transmit separate CIR measurement reports for each antenna in one or more CIR reports. This may involve defining a window around the reference point of each antenna. If the reference points differ for different antennas, the response device 330 may report the relative offset between the reference taps selected to be reported.

[0073]

[0080] In some embodiments, the response device 330 may use a single window determined for all of the multiple antennas. The reference point for the window may include a reference point for a first antenna (or any designated antenna) among the multiple antennas. The reference point may include a reference point based on a synthesized CIR measurement report. The response device 330 may generate a synthesized CIR measurement report by compensating for hardware delay differences between antennas and then adding the tap amplitudes in the time domain.

[0074]

[0081] By using settings for consistent CIR reporting and aligning the CIR reports, the device can improve the accuracy and functionality of RF sensing.

[0075]

[0082] As shown above, Figure 5 is provided as an example. Other embodiments may differ from those described with respect to Figure 5.

[0076]

[0083] Figure 6 shows an exemplary process 600 performed by, for example, a response device according to the present disclosure. The exemplary process 600 is an example in which a response device (e.g., response device 330) performs an operation associated with RF sensing.

[0077]

[0084] As shown in Figure 6, in some embodiments, process 600 may include receiving a signal from the initiating device (block 610).

[0078]

[0085] As shown in Figure 6, in some embodiments, process 600 may include estimating a CIR from the signal, where the signal reflections from one or more objects are represented as multiple taps (block 620).

[0079]

[0080]

[0087] As further shown in Figure 6, in some embodiments, process 600 may include sending a CIR report to the initiating device indicating one or more taps (block 640).
