[0005] A wireless local area network (WLAN) can be formed by one or more wireless access points (APs) that provide a shared wireless communication medium for use by multiple client devices, also referred to as wireless stations (STAs). The basic building block of a WLAN conforming to the IEEE (Institute of Electrical and Electronics Engineers) 802.11 standard family is a Basic Service Set (BSS) managed by the AP. Each BSS is identified by a Basic Service Set Identifier (BSSID) advertised by the AP. The AP may periodically broadcast beacon frames to enable any STA within the AP's wireless range to establish or maintain a communication link with the WLAN.

[0006] In some WLANs, two or more wireless devices can exchange signaling to perform sensing between two or more wireless devices and measure the channel impulse response (CIR).

[0024] The following description relates to some specific examples for the purpose of illustrating innovative aspects of the present disclosure. However, those skilled in the art will readily recognize that the teachings of this specification may be applied in a number of different ways. Some or all of the described examples may be implemented in any device, system, or network capable of transmitting and receiving RF (radio frequency) signals in accordance with one or more of the IEEE (Institute of Electrical and Electronics Engineers) 802.11 standards, IEEE 802.15 standards, Bluetooth® standards as defined by the SIG (Bluetooth Special Interest Group), or LTE (Long Term Evolution), 3G, 4G, or 5G (NR (New Radio)) standards published by the 3GPP (3rd Generation Partnership Project). The described examples may be implemented in any device, system, or network capable of transmitting and receiving RF signals according to one or more of the following technologies or techniques: CDMA (code division multiple access), TDMA (time division multiple access), FDMA (frequency division multiple access), OFDMA (orthogonal FDMA), SC-FDMA (single-carrier FDMA), SDMA (spatial division multiple access), RSMA (rate-splitting multiple access), MUSA (multi-user shared access), SU (single-user) MIMO (multiple-input multiple-output) and MU (multi-user)-MIMO.The described examples may also be implemented using other wireless communication protocols or RF signals suitable for use in one or more of a WPAN (wireless personal area network), WLAN (wireless local area network), WWAN (wireless wide area network), WMAN (wireless metropolitan area network), or IoT (internet of things) network.

[0025] Various aspects generally relate to sensing procedures between two wireless devices communicating in ultra-wide bandwidth (UWB) systems. Some aspects relate more specifically to setting up one or more sensing instances or sensing rounds for one or more individual sensing operations. In some implementations, a first wireless device (e.g., a controller, an initiator) may transmit a sensing session setup request frame indicating a set of parameters for one or more sensing instances. The sensing instances may be associated with the operations of the first wireless device in the UWB system. For each sensing instance, the first wireless device may transmit a sensing control information element including at least a common sensing control configuration and a channel impulse response (CIR) report configuration. A common sensing control configuration may include fields specifying the configuration of a sensing operation during a sensing instance (e.g., whether the sensing operation is mono-static, bi-static, or multi-static, whether the transducer is a transmitting device or a receiving device, and other parameters), and a CIR report configuration may specify one or more parameters associated with a CIR report transmitted to a first wireless device at the end of a sensing instance. The first wireless device may participate in one or more individual sensing operations during one or more sensing instances together with at least a second device (e.g., one or more transducers or controllers), which may include communicating one or more CIR reports.

[0026] Specific aspects of the claimed subject matter described in this disclosure may be implemented to realize one or more of the following potential advantages. In some implementations, by supporting a sensing session setup request frame that indicates a set of parameters for sensing instances, the described techniques may be used to support accurate sensing measurements in UWB systems. Additionally, as described herein, the design of information elements for UWB sensing control may enable communication of sensing configuration parameters between UWB devices participating in sensing. This may allow for compressed message sizes based on enabling efficient bit allocation for different features. Furthermore, the described techniques may support sensing control information elements that enable the configuration of sensing operations and CIR reports, which may improve and simplify sensing measurements (specifically, CIR measurements) for UWB devices. Thus, such systems may experience more accurate sensing, higher data rates, and greater spectral efficiency, among other advantages (since wider bandwidth sensing signaling can provide more accurate sensing-related information).

[0027] FIG. 1 illustrates a schematic diagram of an exemplary wireless communication network (100). The wireless communication network (100) may be, among other examples, elements of a 5G (e.g., NR) network, a 4G (e.g., LTE (Long Term Evolution)) network, WAN (wide area network) access points (APs), PAN (personal area network) access points and devices, or UWB devices (e.g., UWB anchors, UWB tags), or may include these. The wireless communication network (100) may include one or more network entities such as a base station, an AP, or a UWB device (110) (illustrated as a BS, AP, or UWB device (110-a), a pico BS, AP, or UWB device (110-b), a femto BS, AP, or UWB device (110-c), and a relay BS, AP, or UWB device (110-d)). A wireless communication network (100) may also include user equipment (UE) (120) or a number of UEs (120) (illustrated as UE (120-a), UE (120-b), UE (120-c), UE (120-d), and UE (120-e). A base station, AP, or UWB device (110) is a network entity that communicates with the UEs (120). A base station (sometimes referred to as BS) may include, for example, an NR base station, an LTE base station, a Node B, (e.g., in 4G) an eNB, (e.g., in 5G) a gNB, and / or a TRP (transmission reception point). Each base station, AP, or UWB device (110) may provide communication coverage for a specific geographical area. In the 3GPP (Third Generation Partnership Project), the term “cell” may refer to a coverage area of ​​a base station, AP, or UWB device (110) and / or a base station subsystem serving such coverage area, depending on the context in which the term is used.

[0028] In some aspects, the term “base station” or “network entity” may refer to an aggregated base station, a disaggregated base station, an integrated access and backhaul (IAB) node, a relay node, and / or one or more of their components. For example, in some aspects, the term “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 aspects, the term “base station” or “network entity” may refer to a single device configured to perform one or more functions such as those described herein in relation to a base station. In some aspects, the term “base station” or “network entity” may refer to a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of a number of different devices (which may be located in the same geographic location or different geographic locations) may be configured to perform at least a part of a function or to replicate the performance of at least a part of a function, and the term “base station” or “network entity” may refer to any one or more of these different devices. In some aspects, the term “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 aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term “base station” or “network entity” may refer to one of the base station functions and not the other. In this way, a single device may include more than one base station.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.” Network entities may include the components described for base stations, APs, or UWB devices (110).

[0029] A base station, AP, or UWB device (110) can provide communication coverage for a macro cell, a pico cell, a femto cell, and / or other types of cells. A macro cell can cover a relatively large geographical area (e.g., a radius of several kilometers) and allow unrestricted access by UEs (120) with service subscriptions. A pico cell can cover a relatively small geographical area and allow unrestricted access by service-subscribed UEs (120). A femto cell can cover a relatively small geographical area (e.g., a home) and allow restricted access by UEs (120) with an association with the femto cell (e.g., UEs (120) within a closed subscriber group (CSG)). A base station for a macro cell may be referred to as a macro base station. A base station for a pico cell may be referred to as a pico base station. A base station for a femto cell may be referred to as a femto base station or a home-in-home base station. In the example illustrated in FIG. 1, a BS, AP, or UWB device (110-a) may be a macro base station, AP, or UWB device for a macro cell (102-a), a BS, AP, or UWB device (110-b) may be a pico base station, AP, or UWB device for a pico cell (102-b), and a BS, AP, or UWB device (110-c) may be a femto base station, AP, or UWB device for a femto cell (102-c). 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.

[0030] In some implementations, the cell does not necessarily have to be fixed, and the geographical area of ​​the cell may be moved according to the location of a mobile base station (e.g., a mobile base station). In some implementations, base stations, APs, or UWB devices (110) may be interconnected to one or more other base stations, APs, or UWB devices (110) or network entities (not shown) within a wireless communication network (100) via various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transmission network.

[0031] A wireless communication network (100) may include one or more relay stations. A relay station is an entity capable of receiving transmissions of data from an upstream station (e.g., a network entity or UE (120)) and transmitting transmissions of data to a downstream station (e.g., a UE (120) or a network entity). A relay station may be a UE (120) capable of relaying transmissions to other UEs (120). In the example illustrated in FIG. 1, a BS, AP, or UWB device (110-d) (e.g., a relay base station) may communicate with the BS, AP, or UWB device (110-a) and the UE (120-d) to facilitate communication between the BS, AP, or UWB device (110-a) (e.g., a macro base station, AP, or UWB device) and the UE (120-d). Base stations that relay communications may be referred to as relay stations, relay base stations, relay units, etc.

[0032] A wireless communication network (100) may be a heterogeneous network including different types of base stations, such as macro base stations, pico base stations, femto base stations, relay base stations, etc. These different types of base stations, different types of APs, or different types of UWB devices may have different transmission power levels, different coverage areas, and / or different effects on interference in the wireless communication network (100). For example, macro base stations, APs, or UWB devices may have high transmission 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 transmission power levels (e.g., 0.1 to 2 watts).

[0033] A network controller (130) may be coupled to or communicate with a set of network entities and may provide coordination and control over these network entities. The network controller (130) may communicate with network entities via a backhaul communication link. Network entities may communicate with each other indirectly or directly via a wireless or wired backhaul communication link.

[0034] UEs (120) may be scattered throughout the wireless communication network (100), and each UE (120) may be fixed or mobile. The UE (120) may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. The UE (120) may be a cellular phone (e.g., a smartphone), a PDA (personal digital assistant), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a WLL (wireless local loop) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., smart watches, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, and / or any other suitable device configured to communicate via a wireless medium. The UE (120) may be capable of UWB communication.

[0035] Some UEs (120) may be considered as machine-type communication (MTC) or eMTC (evolved or enhanced machine-type communication) UEs. MTC UEs and / or eMTC UEs may include robots, drones, remote devices, sensors, meters, monitors, and / or location tags capable of communicating with, for example, a base station, other devices (e.g., remote devices), or some other entity. Some UEs (120) may be considered as Internet-of-Things (IoT) devices and / or implemented as narrowband IoT (NB-IoT) devices. Some UEs (120) may be considered as Customer Premises Equipment. A UE (120) may be contained within a housing that houses the components of the UE (120), such as processor components and / or memory components. In some implementations, processor components and memory components may be coupled together. For example, processor components (e.g., one or more processors) and memory components (e.g., memory) may be operablely coupled, communicably coupled, electronically coupled, and / or electrically coupled.

[0036] Generally, any number of wireless communication networks (100) may be deployed in a given geographical area. Each wireless communication network (100) may support a specific RAT and may operate on one or more frequencies. The RAT may be referred to as radio technology, air interface, etc. The frequency may be referred to as carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some examples, NR or 5G RAT networks may be deployed. In some examples, WANs, PANs, or UWB networks may be deployed.

[0037] In some implementations, two or more UEs (120) (e.g., illustrated as UE (120-a) and UE (120-e)) may communicate directly using one or more sidelink channels (e.g., without using a network entity as an intermediary to communicate with each other). For example, UEs (120) may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and / or a mesh network. In such examples, the UE (120) may perform scheduling operations, resource selection operations, and / or other operations described elsewhere in this specification, such as those performed by a base station, AP, or UWB device (110).

[0038] Devices in a wireless communication network (100) can communicate using an electromagnetic spectrum that can be subdivided into various classes, bands, channels, etc. by frequency or wavelength. For example, devices in a wireless communication network (100) can communicate using one or more operating bands. The UWB frequency bandwidth can be greater than 500 MHz. In 5G NR, two initial operating bands were identified as frequency range designations FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 52.6 GHz). It should be understood that although part of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "Sub-6 GHz" band in various literature and papers. A similar naming issue arises regarding FR2, which is often (interchangeably) referred to as the "millimeter wave" band in literature and papers, despite being different from the EHF (extremely high frequency) band (30 GHz to 300 GHz) identified as the "millimeter wave" band by the ITU (International Telecommunications Union).

[0039] Frequency ranges between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR research has identified the operating band for these mid-band frequencies as the frequency range designation FR3 (7.125 GHz to 24.25 GHz). Frequency bands within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 to mid-band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands were 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.

[0040] With the above examples in mind, unless otherwise specifically stated, it should be understood that the term “sub-6 GHz,” etc., as used herein, may broadly refer to frequencies that may be less than 6 GHz, may be within FR1, or may include intermediate-band frequencies. Additionally, unless otherwise specifically stated, it should be understood that the term “millimeter wave,” etc., as used herein, may broadly refer to frequencies that may include intermediate-band frequencies, may be within FR2, FR4, FR4-a, or FR4-1, and / or FR5, or may be within the EHF band. It is considered that frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and that the techniques described herein are applicable to these modified frequency ranges.

[0041] In some aspects, the responding device (e.g., UE (120), network entity) may include a communication manager (140 or 150). As described in more detail elsewhere in this specification, the communication manager (140 or 150) receives a signal from the initiating device and estimates a channel impulse response (CIR) from the signal, representing signal reflections from one or more objects as a plurality of taps; and may select one or more taps from the plurality of taps based at least partially on a configuration for providing consistent CIR reports. The communication manager (140 or 150) may transmit a CIR report indicating one or more taps to the initiating device.

[0042] In some aspects, the initiating device (e.g., UE (120), network entity) may include a communication manager (140 or 150). As described in more detail elsewhere in this specification, the communication manager (140 or 150) transmits a signal comprising a plurality of packets; and may receive a CIR report for each of the plurality of packets from a responding device. The communication manager (140 or 150) may sort the CIR reports across the plurality of packets to identify a target object, the location of the target object, or the movement of the target object by using one or more tabs within the CIR report for each packet. The communication manager (140 or 150) may perform an action based at least partially on the target object, the location of the target object, or the movement of the target object. Additionally or alternatively, the communication manager (140 or 150) may perform one or more other operations described herein.

[0043] As indicated above, FIG. 1 is provided as an example. Other examples may differ from those described with respect to FIG. 1.

[0044] FIG. 2 illustrates an example (200) in which a network entity (e.g., a base station, AP, or UWB device (110)) communicates with a UE (120) in a wireless communication network (100) according to the present disclosure. In the base station, AP, or UWB device (110), T Dog antennas ( T A set of antennas (234-a to 234-t), such as ≥1), may be mounted on the UE (120). R Dog antennas ( R A set of antennas (252-a to 252-r) such as ≥1) may be installed. The WAN access point may also include components as described for a base station, AP, or UWB device (110), and may also operate according to Institute of Electrical Engineers (IEEE) standards (e.g., IEEE 802).

[0045] In a base station, AP, or UWB device (110), a transmitting processor (220) may receive data intended for a UE (120) (or a set of UEs (120)) from a data source (212). The transmitting processor (220) may select one or more modulation and coding schemes (MCS) for the UE (120) based at least partially on one or more channel quality indicators (CQI) received from the UE (120). The base station, AP, or UWB device (110) may process data for the UE (120) (e.g., encoding and modulation) based at least partially on the selected MCS(s) for the UE (120) and may provide data symbols for the UE (120). The transmitting processor (220) can process system information (e.g., semi-static resource partitioning information) and control information (e.g., CQI requests, grants, and / or upper-layer signaling) and provide overhead symbols and control symbols. The transmitting processor (220) can generate reference symbols for reference signals (e.g., cell-specific reference signal (CRS) or demodulation reference signal (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmitting (TX) MIMO (multiple-input-multiple output) processor (230) can, if applicable, perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, and provide a set of output symbol streams (e.g., TA corresponding set of modems (232) (e.g.,) illustrated as modems (232-a to 232-t) with output symbol streams) T It can be provided to (232 modems). For example, each output symbol stream can be provided to a modulator component (shown as MOD) of a modem (232). Each modem (232) may use an individual modulator component to process an individual output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem (232) may additionally use an individual modulator component to process the output sample stream (e.g., convert to analog, amplify, filter, and / or upconvert) to obtain a downlink signal. The modems (232-a to 232-t) may provide a set of downlink signals (e.g., T A corresponding set of antennas (234) (e.g.,) illustrated as antennas (234-a to 234-t) for the downlink signals) T It can transmit through the antennas.

[0046] In the UE (120), a set of antennas (252) (illustrated as antennas (252-a to 252-r)) can receive downlink signals from a base station, AP, or UWB device (110) and / or other base stations, APs, or UWB devices (110), and a set of received signals (e.g., R A set of modems (254) (e.g.,) described as modems (254-a to 254-r) receiving signals) RIt can be provided to (254) modems. For example, each received signal can be provided to a demodulator component (shown as DEMOD) of a modem (254). Each modem (254) may use an individual demodulator component to condition the received signal (e.g., filtering, amplification, down-conversion, and / or digitization) to acquire input samples. Each modem (254) may use a demodulator component to further process the input samples (e.g., for OFDM) to acquire received symbols. A MIMO detector (256) can acquire received symbols from the modems (254), perform MIMO detection on the received symbols if applicable, and provide the detected symbols. The receiving processor (258) can process the detected symbols (e.g., demodulate and decode), provide the decoded data for the UE (120) to the data sink (260), and provide the decoded control information 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 determine, among other examples, 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 implementations, one or more components of the UE (120) may be contained in the housing (284).

[0047] The network controller (130) may include a communication unit (294), a controller / processor (290), and a memory (292). The network controller (130) may include one or more devices, for example, in a core network. The network controller (130) may communicate with a network entity through the communication unit (294).

[0048] One or more antennas (e.g., antennas (234-a to 234-t) and / or antennas (252-a to 252-r)) may include, among other examples, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays. 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 antenna elements on the same plane, a set of antenna elements on a different plane, and / or one or more antenna elements coupled to one or more transmitting and / or receiving components, e.g., one or more components of FIG. 2.

[0049] On the uplink, in the UE (120), the transmitting processor (264) can receive and process data from the data source (262) and control information from the controller / processor (280) (e.g., reports including RSRP, RSSI, RSRQ, and / or CQI). The transmitting processor (264) can generate reference symbols for one or more reference signals. Symbols from the transmitting processor (264) may be precoded by the TX MIMO processor (266), if applicable, further processed by the modems (254) (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to a network entity. In some implementations, the modem (254) of the UE (120) may include a modulator and a demodulator. In some implementations, the UE (120) includes a transceiver. The transceiver may include any combination of antenna(s) (252), modem(s) (254), MIMO detector (256), receiving processor (258), transmitting processor (264), and / or TX MIMO processor (266). The transceiver may be used by a processor (e.g., controller / processor (280)) and memory (282) to perform aspects of any of the methods described herein (e.g., with reference to FIGS. 3 through 9).

[0050] In a network entity (e.g., base station, AP, or UWB device (110)), uplink signals from a UE (120) and / or other UEs are received by antennas (234), processed by a modem (232) (e.g., a demodulator component shown as a DEMOD of the modem (232)), detected by a MIMO detector (236) if applicable, and further processed by a receiving processor (238) to obtain decoded data and control information transmitted by the UE (120). The receiving processor (238) may provide the decoded data to a data sink (239) and provide the decoded control information to a controller / processor (240). The network entity may include a communication unit (244) and may communicate with a network controller (130) through the communication unit (244). A network entity may include a scheduler (246) for scheduling one or more UEs (120) for downlink and / or uplink communications. In some implementations, the modem (232) of the network entity may include a modulator and a demodulator. In some implementations, the network entity includes a transceiver. The transceiver may include any combination of antenna(s) (234), modem(s) (232), MIMO detector (236), receive processor (238), transmit processor (220), and / or TX MIMO processor (230). The transceiver may be used by a processor (e.g., controller / processor (240)) and memory (242) to perform aspects of any of the methods described herein (e.g., with reference to FIGS. 3 through 9).

[0051] The controller / processor of the network entity of FIG. 2 (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) may perform one or more techniques associated with RF sensing as 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) of FIG. 2 may perform or direct the operations of, for example, the process of FIG. 10 and / or other processes as described in this specification. Memory (242) and memory (282) may store data and program code for the network entity and the UE (120), respectively. In some implementations, memory (242) and / or memory (282) may comprise a non-transient computer-readable medium that stores one or more instructions for wireless communication (e.g., code and / or program code). For example, when one or more instructions are executed by one or more processors of a network entity and / or UE (120) (e.g., directly, or after compiling, converting, and / or interpreting), one or more processors, UE (120), and / or network entity may perform or direct other processes such as the process of FIG. 6, the process of FIG. 7, and / or other processes as described herein. In some implementations, executing instructions may include, among other examples, executing instructions, converting instructions, compiling instructions, and / or interpreting instructions.

[0052] In some aspects, a response device (e.g., UE (120), network entity) comprises means for receiving a signal from a starter device and means for estimating a CIR from the signal, representing signal reflections from one or more objects as a plurality of tabs; means for selecting one or more tabs from the plurality of tabs based at least partially on a configuration for providing consistent CIR reports; and / or means for transmitting a CIR report indicating one or more tabs to the starter device. In some aspects, means for the response device to perform the operations described herein may include, for example, a communication manager (150), a transmission processor (220), a TX MIMO processor (230), a modem (232), an antenna (234), a MIMO detector (236), a reception processor (238), a controller / processor (240), a memory (242), or a scheduler (246). In some aspects, means for the response device to perform the operations described herein may include, for example, one or more of a communication 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).

[0053] In some aspects, an initiating device (e.g., UE (120), network entity) comprises means for transmitting a signal comprising a plurality of packets; means for receiving a CIR report for each of the plurality of packets from a responding device; means for aligning the CIR reports across the plurality of packets to identify a target object, a location of the target object, or a movement of the target object using one or more tabs in the CIR report for each packet; and / or means for performing an action based at least partially on the target object, the location of the target object, or the movement of the target object. In some aspects, the means for the initiating device to perform the operations described herein may include, for example, a communication manager (150), a transmitting processor (220), a TX MIMO processor (230), a modem (232), an antenna (234), a MIMO detector (236), a receiving processor (238), a controller / processor (240), a memory (242), or a scheduler (246). In some aspects, means for the initiation device to perform the operations described herein may include, for example, one or more of a communication 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).

[0054] Although the blocks of FIG. 2 are exemplified as separate components, the functions described above with respect to the blocks may be implemented as a single hardware, software, or combined component, or as various combinations of components. For example, the functions described with respect to the transmit processor (264), receive processor (258), and / or TX MIMO processor (266) may be performed by or under the control of the controller / processor (280).

[0055] As indicated above, FIG. 2 is provided as an example. Other examples may differ from those described with respect to FIG. 2.

[0056] FIG. 3 illustrates an example (300) of RF sensing. RF sensing can be used to identify a target object (310). Example (300) illustrates an example of bi-static unidirectional sensing. An initiating device (320) (e.g., UE (120), network entity) can transmit signals reflected from the target object (310) (e.g., user, other person, body part, animal, robot) and other surfaces. A responding device (330) (e.g., UE (120), network entity) can receive the direct signal and the reflections of the signal. The responding device (330) can estimate the CIR from the signal. While the direct signal can be received, RF sensing can focus on the reflected signals and distinguish the reflected signals from the direct signal by intensity, time, or other information. The CIR can represent or characterize the signal reflections from one or more objects as one or more taps. The tabs may indicate the signal strength of reflected signals received at different points in time (e.g., t0, t1, etc.). As illustrated by reference number (335) in FIG. 3, the response device (330) may generate a CIR report (336) (e.g., a CIR measurement report) containing one or more of the tabs (338). The response device (330) may transmit the CIR report (336) to the initiation device (320), and the initiation device (320) may identify a target object (310) from the tabs (338) of the CIR report (336).

[0057] RF sensing has different requirements than wireless communications. In the IEEE standard 802.15, UWB data communication does not rely on any channel consistency from one packet to the next. However, in the case of UWB ranging, inconsistent channel measurements from one packet to the next can cause CIR reports (336) for multiple packets to appear as random taps. As a result, CIR reports (336) may not be useful for RF sensing applications. RF sensing makes inferences about changes in the environment by measuring changes in wireless channels. If consistent CIR measurements and reporting are not satisfied, the wireless device may determine that the measured and reported changes in the wireless channel are due to changes in the physical environment rather than to the wireless device itself.

[0058] According to the various aspects described herein, the response device (330) may select one or more reference tabs that the initiation device (320) can use to align CIR reports (336) from each of the multiple packets. A tab may refer to an energy rise of the channel impulse response at a certain point in time or at an opportunity to indicate a direct or reflected signal. A tab 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. Alignment of CIR reports may include aligning CIR reports at least in a timely manner. This may include, for example, identifying tabs in the first CIR report (e.g., satisfying thresholds) that appear at the same times or cases as the tabs in the second CIR report so that a tab for a direct or reflected signal in the first CIR report is matched with a tab for the same direct or reflected signal in the second CIR report. By aligning the CIR reports, the initiation device (320) can better identify the target object (310), the movement of the target object (310), or other attributes of the target object (310). The initiation device (320) can take more appropriate action with better identification of the target object (310) and conserve processing resources and signaling resources. For example, among other RF sensing uses, the initiation device can better detect the location of a body part of a user (e.g., a person, a robot, an autonomous device), detect user activity (e.g., gestures or breathing patterns of a person or animal), identify objects near the user, or detect the movement of objects around the user.

[0059] As illustrated in the example (300) of FIG. 3, the initiating device (320) can transmit a signal, and the responding device (330) can receive reflections of the signal from one or more objects including the target object (310).

[0060] In some aspects, the response device (330) may be configured to select one or more reference points to be provided in the CIR report (336) (e.g., by the initiation device (320), by another device, or at production). The reference point may be the earliest tap, the strongest tap, the center of mass of the taps, the packet detection time, or any other specific tap or time point. The response device (330) may use a configuration to provide consistent CIR reports. Consistent CIR reports may be CIR reports that work together to provide accurate RF sensing information for objects. Consistent CIR reports may include CIR reports having information (e.g., taps, reference points) that the initiation device can use to align the CIR reports in time to match reflected signals to objects over time in order to identify objects when movement is involved. The configuration can specify which tabs to select for the CIR report, including how many tabs exist before or after a reference point or how long they are before or after the reference point, in order to collect the tabs.

[0061] FIG. 4 illustrates an example (400) of a PPDU available for communications between UWB devices. UWB wireless devices (e.g., including an initiator and one or more transponders) can communicate in UWB systems using relatively low power, which can be useful for applications such as security ranging, sensing (e.g., presence detection), and high-data-rate communications, among other applications.

[0062] In some implementations, the initiator may transmit different frame structures (e.g., PPDUs) for UWB communications, wherein the frame structures may include different fields used for specific functions. For example, such PPDUs may include different combinations of a SYNC field, a start of frame delimiter (SFD) field, one or more physical layer (PHY) fields, a PHY payload field, a scrambled timestamp sequence (STS) field, or a sensing (SENS) field.

[0063] A SYNC field included at the beginning of a UWB packet (also referred to as a frame or PPDU described herein) may be used for synchronization between wireless devices (a starter and one or more transceivers). Additionally, the UWB packet may include an SFD field for time-stamping the transmission, which may be useful for ranging. In some implementations, the UWB packet may include one or more PHR fields (e.g., PHR1, PHR2, PHR fields) capable of providing PHY information (e.g., information regarding the payload) to one or more transceivers. Additionally or alternatively, the UWB packet may include a PHY payload field, a STS (scrambled timestamp sequence) field, or both. The PHY payload field may carry actual data (e.g., data bits), timestamp information, or other data. The STS field may provide additional information that can improve the accuracy of ranging measurements. Additionally, the SENS field of a UWB packet can provide an appropriate sequence and waveform for high-quality RF sensing. In some implementations, the UWB packet may include both a payload and SENS fields.

[0064] In some implementations, UWB packets may include a SENS field for scheduling and controlling sensing sessions between wireless devices. Sensing may occur in a mono-static, bi-static, or multi-static manner. For example, in a mono-static sensing operation (an example described herein with reference to FIG. 3), a single wireless device (e.g., a wireless device acting as an initiator and a transceiver) transmits a UWB frame, receives a reflection of the UWB packet from an object (e.g., a target or a reflector), and can estimate the characteristics of the object (e.g., movement, presence or absence of the object, how far the object is located from the wireless device, and other characteristics).

[0065] Alternatively, in a bi-static or multi-static sensing operation, two or more wireless devices may participate in the sensing operation. In such implementations, the first wireless device may be an initiator and the second wireless device may be a transceiver, or the second wireless device may be an initiator and the first wireless device may be a transceiver. For example, as an initiator, the first wireless device may transmit a UWB packet that may be reflected from an object for reception by the second wireless device as a transceiver, so that the second wireless device can estimate the characteristics of the object using sensing.

[0066] FIG. 3 illustrates a number of examples of PPDUs for sensing in a UWB system. For example, a dynamic data mode packet may include a SYNC field, an SFD field, a PHR 1 field, a PHR 2 field, and a PHY payload. STS packet configuration 0 may include a SYNC field, an SFD field, a PHY field, and a PHY payload field. STS packet configuration 1 may include a SYNC field, an SFD field, an STS field, a PHR field, and a PHY payload field. STS packet configuration 2 may include a SYNC field, an SFD field, a PHR field, a PHY payload field, and an STS field. STS packet configuration 3 may include a SYNC field, an SFD field, and an STS field. Additionally, sensing packet configuration 0 may include a SYNC field, an SFD field, and a SENS field. Sense packet configuration 1 may include a SYNC field, an SFD field, a SENS field, a PHR field, and a PHY payload field. Detect packet configuration 2 may include a SYNC field, an SFD field, a PHR field, a PHY payload field, and a SENS field. Other PPDUs or UWB packet formats may be supported.

[0067] FIG. 5 illustrates an example of a diagram (500) supporting RF sensing control for a UWB system according to some aspects of the present disclosure. The diagram (500) may be implemented to implement or facilitate aspects of a WLAN (100). For example, the diagram (500) illustrates communication between a wireless device (502) and a wireless device (504) via a communication link (506), and the wireless device (502) and the wireless device (504) may each be an example of a STA or AP as illustrated in FIG. 1 and described with reference thereto. In some implementations, the wireless device (502) and the wireless device (504) may support one or more signaling or messaging designs to support a sensing measurement procedure in a UWB system (using a bandwidth of approximately 500 MHz). In some aspects, the wireless device (502) may be an initiating wireless device or an initiating STA (ISTA) (also referred to herein as a controller), and the wireless device (504) may be a responding wireless device or a responding STA (RSTA) (also referred to herein as a controlled device). Alternatively, the wireless device (504) may be an ISTA, and the wireless device (502) may be an RSTA. Additionally, although referred to as an ISTA or RSTA, such a role of an ISTA or RSTA may be taken by either a STA or an AP.

[0068] Wireless devices can communicate in UWB systems using relatively low power, which may be useful for applications such as security ranging, sensing (e.g., presence detection), and high-data-rate communications, among other applications. As described in the specification with reference to FIG. 4, a wireless device (502) or a wireless device (504) may transmit different frame structures for UWB communications, wherein the frame structures may include different fields used for specific functions.

[0069] In some implementations, UWB packets may include a SENS field for scheduling and controlling sensing sessions between wireless devices. Sensing may occur in a mono-static, bi-static, or multi-static manner. For example, in a mono-static sensing operation, a single wireless device (e.g., a wireless device (502) acting as an initiator and transceiver) transmits a UWB frame, receives a reflection of the UWB packet from an object (e.g., a target or a reflector), and can estimate the characteristics of the object (e.g., movement, presence or absence of the object, how far the object is located from the wireless device, and other characteristics). Alternatively, in a bi-static or multi-static sensing operation, two or more wireless devices may participate in the sensing operation. In such implementations, the wireless device (502) may be an initiator and the wireless device (504) may be a transceiver, or the wireless device (504) may be an initiator and the wireless device (502) may be a transceiver. For example, as an initiator, the wireless device (502) may transmit a UWB frame that can be reflected from an object for reception by the wireless device (504) as a transceiver, so that the wireless device (504) can estimate the characteristics of the object using sensing. To perform sensing, the wireless device (504) may measure a CIR that can indicate channel behavior. That is, because an object or any other reflector between the wireless devices may be added to the CIR of the channel, the wireless device (504) may measure the CIR to understand the environment and changes in the environment, including object movement, object ranges, and other environmental information.

[0070] To support the sensing measurement procedure, wireless device (502) and wireless device (504) may participate in the setup of a sensing session, one or more sensing measurement instances (e.g., sensing rounds or measurement rounds), and the termination of the sensing session. During the session setup, wireless device (502) (initiator or controller) may transmit a sensing session setup request frame to wireless device (504) (responder or controlled). The sensing session setup request frame may indicate a set of parameters for one or more sensing instances of the sensing session (e.g., sensing time instances or sensing rounds). In some implementations, the set of parameters may indicate, among other parameters, the RF channel, frequency, time duration, and packet type for which the wireless devices will perform sensing. Additionally, the sensing session setup request frame may indicate the roles of wireless device (502) and wireless device (504), which may be established before the sensing session is initiated. For example, a detection session setup request frame can indicate which wireless devices are ISTAs or RSTAs.

[0071] A wireless device (504) may transmit a sensing session setup response frame (also referred to herein as a feedback frame) to a wireless device (502) that accepts or rejects a set of parameters indicated in a sensing session setup request frame. For example, if the wireless device (504) accepts the set of parameters, the sensing session setup response frame may include an acknowledgment (ACK) to indicate acceptance, and the wireless devices may proceed to the sensing measurement phase of the sensing session. Alternatively, if the wireless device (504) rejects the set of parameters, the sensing session setup response frame may indicate rejection and indicate a second set of operation parameters provided by the wireless device (504). The wireless devices (504) may continue to transmit these sensing session setup request and response frames until they agree to the set of parameters.

[0072] Wireless devices may initiate a sensing measurement phase of a sensing operation based on agreeing on a set of parameters. The sensing measurement phase may include one or more sensing instances (also referred to herein as sensing measurement instances) capable of performing one or more individual sensing operations, which may include the wireless devices performing CIR measurements of a waveform. Thus, a wireless device (504) (transponder) may generate one CIR measurement per sensing instance. In this way, if wireless devices intend to perform sensing over a period of time to detect some activity or presence of some objects, wireless device (502) and wireless device (504) may utilize a certain number of sensing measurement instances to accurately measure CIR over time.

[0073] Each detection instance may include a detection control phase (508), a detection phase (510), and a detection measurement report phase (512). Additionally, wireless devices (502) and (504) may follow a detection round / block structure similar to that for a ranging operation for a detection operation. The detection round / block structure may be based on a detection block that may include a quantity of N-1 detection rounds (such as detection round 0, detection round 1, detection round 2, detection round 3, ..., detection round N-1). Each detection round may include a quantity of M-1 detection slots (e.g., detection round 0 may include detection slot 0, detection slot 1, detection slot 2, detection slot 3, ..., detection slot M-1). Based on the detection round / block structure, a detection instance may occur during one detection round (i.e., the time duration of one detection round may be the same as the time duration of one detection instance). In such implementations, wireless devices may use detection slots for specific functions during a detection instance including during a detection control phase (508), a detection phase (510), and a detection measurement report phase (512).

[0074] During the detection control phase (508), the wireless device (502) and the wireless device (504) may update a set of parameters configured via a detection session setup request frame for a specific detection instance. For example, the wireless devices may use the detection control phase (508) of the detection instance to update the channel, packet, or other parameters for which a detection operation will be performed during the detection instance. During the detection control phase (508) for each of one or more detection instances, the wireless device (502) may transmit a detection control information element (514) to configure parameters for the detection instance.

[0075] To display the sensing control information element (514), the wireless device (502) (controller or initiator) may transmit the application control (AC) information element to the wireless device (504) during the sensing control phase (508) of each active sensing instance (sensing round). The AC information element may include a set of fields spanning two octets (also referred to herein as information elements), and the set of fields constitutes a ranging operation, data communication, sensing operation, or time difference on arrival (TdoA) operation in each instance. For example, the AC information element may include a content control field indicating which content will be included in the AC information element, and a session identifier (ID) field indicating an ID associated with the ranging, data communication, sensing, or TdoA session (operation). Additionally or alternatively, the AC information element may include block, round, and slot duration fields. If AC information is associated with a sensing session, for example, such fields may indicate the duration (time) of sensing blocks, sensing rounds, and sensing slots for a sensing instance.

[0076] Additionally, the AC information element may include a set of variable-bit control information elements that allow wireless devices to display or change parameters for ranging, data communication, sensing, or TdoA sessions. For example, the AC information element may include a ranging control information element, a data communication control information element, a sensing control information element (514), and a TdoA information element.

[0077] The detection control information element (514) may display a set of fields including a common detection control presence field (516), a CIR report parameters presence field (518), a frequency stitching parameters presence field (520), a common detection control configuration field (522), a CIR report parameters configuration field (524), and a frequency stitching parameters configuration field (526). The common detection control presence field (516), the CIR report parameters presence field (518), and the frequency stitching parameters presence field (520) may use a 1-bit flag to indicate the presence of the common detection control configuration field (522), the CIR report parameters configuration field (524), and the frequency stitching parameters configuration field (526), ​​respectively. Additional details regarding the common detection control configuration field (522), the CIR report parameters configuration field (524), and the frequency stitching parameters configuration field (526) are illustrated by FIGS. 6 through 9 and described with reference thereto.

[0078] After the detection control phase (508), the wireless device (502) and the wireless device (504) may enter the detection phase (510) of the detection instance. The detection phase may begin when the wireless device (502) transmits a physical layer packet (e.g., PPDU) of the physical layer packet format type agreed upon during the detection control phase (508). The wireless device (502) may transmit a packet (e.g., a sequence of waveforms) that is reflected from an object or target and can be received by the wireless device (504) in a bi-static or multi-static system or by the wireless device (502) in a mono-static system. The transceiver wireless device (502) or the wireless device (504) may estimate the CIR (or otherwise measure the channel) during the detection phase (510).

[0079] After receiving the packet, the wireless device (502) or the wireless device (504) may re-report the CIR to the wireless device (502) (initiator) during the detection measurement report phase (512). The wireless device (502) or the wireless device (504) may transmit the CIR report via in-band or out-of-band methods. Additionally, the wireless devices may support two types of detection measurement reports, including a MAC layer management entity report used to transmit detection measurement results to the application layer of the first wireless device, and an over-the-air CIR measurement report.

[0080] FIG. 6 illustrates an example of a control diagram (600) that supports RF sensing control for a UWB system according to some aspects of the present disclosure. The control diagram (600) may represent an example of a common sensing control configuration field (522) described herein with reference to FIG. 5 and may support a set of fields related to a sensing instance of a sensing operation in a UWB system. For example, for each sensing instance (sensing round) of a sensing operation, a wireless device (502) and a wireless device (504) may display a common sensing control configuration field in a sensing control information element (514) during a sensing control phase (508).

[0081] In some aspects, the common sensing control configuration field may include a set of fields that constitute one or more parameters of a sensing instance, regardless of the simplicity or complexity of individual sensing operations. The common sensing control configuration field may include a sensing mode field (602) (e.g., 1 bit), a responder role field (604) (e.g., 1 bit), a sensing packet format field (606) (e.g., up to 2 bits), and a reserved field (608) (e.g., up to 3 bits). The sensing mode field (602) may be a 1-bit field indicating whether the sensing operation in a given sensing instance is mono-static, bi-static, or multi-static. A mono-static detection operation may include one transducer (wireless device (502) or wireless device (504)), a bi-static detection operation may include two transducers (wireless device (502) and wireless device (504)), and a multi-static detection operation may include more than two transducers (wireless device (502), wireless device (504), and additional STAs or APs).

[0082] The transponder role field (604) may be a 1-bit field indicating whether the transponder is a transmitter (indicated by a bit having a value of 0) or a receiver (indicated by a bit having a value of 1). That is, since an initiator (e.g., a controller) can initiate a sensing session and the transponder (e.g., a controlled entity) can coordinate with the initiator to participate in the sensing session, the transponder may be a transmitter (e.g., a wireless device (502)) or a receiver (e.g., a wireless device (504)). In this way, the roles of transmitter and receiver are independent of the roles of initiator and transponder in the UWB sensing operation, and therefore, the transponder role field (604) within the common sensing control configuration field may indicate whether the transponder corresponds to a transmitter or a receiver. Additionally, the common sensing control configuration field may be transponder-specific. That is, the wireless device (502) can transmit a common detection control configuration field in a MAC frame associated with the MAC address of a specific transceiver so that each transceiver can receive information regarding its own detection mode, transceiver role, and other information.

[0083] In some aspects, wireless devices may use different types of packets for sensing operations. The sensing packet format field (606) of the common sensing control configuration field may indicate which physical layer packet format (e.g., PPDU or other types of packets or waveforms) will be used to perform sensing during a specific sensing instance. The packet type may correspond to the type of physical layer packet format or waveform that the transmitter transmits over-the-air during the sensing instance for measurement. The reserved field (608) of the common sensing control configuration field may include one or more reserved bits for future use.

[0084] FIG. 7 illustrates an example of a control diagram (700) that supports RF sensing control for a UWB system according to some aspects of the present disclosure. The control diagram (700) may represent an example of a CIR report parameter configuration field (524) described herein with reference to FIG. 5 and may support a set of fields related to a CIR report associated with a sensing instance (sensing round) of a sensing operation in a UWB system. For example, for each sensing instance of a sensing operation, a wireless device (502) and a wireless device (504) may display a CIR report parameter configuration field in a sensing control information element (514) during a sensing control phase (508). The CIR report parameter configuration field may display parameters that the wireless device (502) or the wireless device (504) can use to transmit a CIR report for the corresponding sensing instance.

[0085] The CIR report parameter configuration field may include a set of parameters (configuration) for generating and transmitting a CIR measurement report corresponding to a detection instance when requested by an initiator. For example, the CIR report parameter configuration field may include a CIR field (702) that specifies the quantity of bits (the number of CIR I / Q (in-phase / quadrature) bits) that the wireless device can use to report CIR measurements. Additionally or alternatively, the CIR report parameter configuration field may include one or more 1-bit fields indicating whether to process the CIR before communicating in the CIR report. For example, fields (708), (710), and (712) may indicate processing the CIR report to generate range, velocity, and angle-of-arrival (AOA) for each object or target, respectively. If a bit in any of these fields has a value of 1, the wireless device may process the CIR accordingly (instead of reporting unprocessed CIR measurements).

[0086] In some implementations, the wireless device may report a set of CIR measurements over time by representing CIR in a bitmap. Therefore, the CIR report parameter configuration field may include a bitmap mode field (706) of up to two bits indicating a bitmap mode associated with the bitmap. Bitmap mode 0 may indicate that the initiator will select a bitmap from a predefined subset of bitmaps, bitmap mode 1 may indicate that the initiator will select a bitmap from a configuration not specific to a predefined subset of bitmaps, and bitmap mode 2 may indicate that the transceiver will select a bitmap and report the selected bitmap to the initiator. Additional details regarding bitmap mode 0 indicated in the bitmap mode field (706) are illustrated by FIG. 8 and described with reference thereto.

[0087] In some aspects, the CIR report parameter configuration field may include a bitmap length field (704), a bitmap offset field (714), a bitmap sub-window length field (716), a bitmap gap field (718), a bitmap field (720), or any combination thereof, which may include variable quantities of bits. Each of these bitmap-related fields may be included in the CIR report parameter configuration field based on which bitmap mode is displayed in the bitmap mode field (706). For example, if the bitmap mode field (706) displays bitmap mode 0, the initiator may display a selected bitmap from a predefined subset of bitmaps using the bitmap length field (704), the bitmap offset field (714), the bitmap sub-window length field (716), the bitmap gap field (718), or a combination thereof (and the bitmap field (720) may be excluded from the CIR report parameter configuration field). That is, bitmaps within a predefined subset may have known lengths, gaps, and other configured values. Thus, by indicating such values ​​in the fields of the CIR report parameter configuration fields, the initiator can define a selected bitmap. Additional details regarding an example of a selected bitmap are illustrated by FIG. 8 and described with reference thereto.

[0088] If the bitmap mode field (706) indicates bitmap mode 1, the initiator may use the bitmap field (720) to indicate a bitmap excluded from a predefined subset of bitmaps. That is, instead of indicating values ​​associated with a known bitmap through the bitmap length field (704), bitmap offset field (714), bitmap sub-window length field (716), bitmap gap field (718), or a combination thereof, the initiator may explicitly indicate a selected bitmap using a variable number of bits within the bitmap field (720) (and the aforementioned fields may be excluded from the CIR report parameter configuration fields).

[0089] FIG. 8 illustrates an example of a diagram (800) supporting RF sensing control for a UWB system according to some aspects of the present disclosure. The diagram (800) may illustrate bitmap configurations (802-a) and bitmap configurations (802-b) capable of representing examples of bitmaps (also referred to herein as CIR bitmaps) selected from a predefined subset of bitmaps for bitmap mode 0, as described herein with reference to FIG. 7. In some implementations, for each sensing instance (sensing round) of a sensing operation, a wireless device (502) or a wireless device (504) may transmit a CIR report to display one or more CIR measurements, wherein the CIR report may be formatted as a bitmap.

[0090] As described in this specification, wireless device (502) and wireless device (504) may participate in a set of sensing operations over time to acquire sensing measurements. For example, wireless device (504) may acquire one CIR measurement (also referred to as a CIR tab in this specification) per sensing instance, and thus, wireless device (504) may use multiple sensing instances to acquire multiple CIR tabs over time. Wireless device (504) may transmit a CIR report to wireless device (502) upon request, and the CIR report may display CIR tabs based on a CIR bitmap. The CIR bitmap may be a sequence of 1s and 0s having a duration of the sensing window duration. In the CIR bitmap, 1 may indicate that the corresponding tab will be reported, and 0 may indicate that the corresponding tab will be excluded from the report. In other words, the CIR bitmap can indicate which CIR measurements will be included in the CIR report and which CIR measurements can be omitted from the CIR report.

[0091] To limit the test burden for the required CIR report bitmap mode (bitmap mode 0 if the initiator specifies the bitmap), wireless devices may support specific bitmap configurations (e.g., bitmap configuration (802-a) and bitmap configuration (802-b)). For example, the CIR bitmap is M = Can have a length of {32, 64, 128, 256} bits (1s and 0s). For each CIR bitmap, the same length L = {16, 32, … , M There can exist two strings of 1s having { / 2}. That is, length L The strings are of length MSmaller sensing sub-windows within a larger sensing window can be represented. As described herein with reference to FIG. 7, the length M can correspond to the bitmap length field (704), and the length L It can correspond to the bitmap sub-window length field (716). That is, the bitmap sub-window length field (716) is a larger window length M It can indicate the lengths of smaller interest sub-windows within. Additionally, gaps between strings of 1s. G may exist, and this About It can be expressed as. For example, the bitmap composition (802-a) is a gap It can correspond to, and the bitmap configuration (802-b) is gap It can correspond to. That is, the bitmap gap field (718) is the length of the gap between smaller sub-windows. L It can display. Note that wireless devices may support different bitmap configurations.

[0092] In the example of FIG. 8, the wireless device (504) is M A CIR report of CIR can be generated with a duration of (e.g., 32 tabs). However, the wireless device (504) may not intend to report all the tabs for the entire duration (some data may not be interesting or valuable, and the report may be too long for efficient transmission). Therefore, bitmap configurations (802-a) and CIR bitmaps can enable the wireless device (504) to report CIR for specific parts of the detection window related to the wireless device (502).

[0093] As described with reference to FIG. 7, the bitmap mode field (706) of the CIR report parameter configuration field may indicate bitmap mode 0 (the initiator will select a bitmap from a predefined subset of bitmaps). For the bitmap configuration (802-a) (corresponding to the bitmap selected by the initiator), the bitmap length field (704) of the CIR report parameter configuration field is length M It can display, and the bitmap sub-window length field (716) is length L It can display, and the bitmap gap field (718) is gap It can be indicated, wherein any CIR tabs measured during a gap can be excluded from the CIR report. That is, the CIR report includes tabs during durations (804-a) and (804-b) (distributed across the detection window) and can exclude tabs during gaps (806-a) and (806-b) (distributed across the detection window). Similarly, for the bitmap configuration (802-b), the bitmap length field (704) is length M It can display, and the bitmap sub-window length field (716) is length L It can display, and the bitmap gap field (718) is gap It can display. Therefore, the CIR report can include taps for durations (804-c) and (804-d) (at the beginning and end of the detection window) and exclude taps for a gap (806-c) (in the middle of the detection window).

[0094] FIG. 9 illustrates an example of a control diagram (900) that supports RF sensing control for a UWB system according to some aspects of the present disclosure. The control diagram (900) may be an example of a frequency stitching parameter configuration field (526) described herein with reference to FIG. 5 and may support a set of fields related to performing frequency stitching for UWB sensing. For each sensing instance (sensing round) of a sensing operation, the wireless device (502) and the wireless device (504) may display a frequency stitching parameter presence field in the sensing control information element (514) during the sensing control phase (508).

[0095] The frequency stitching parameter presence field may indicate a set of control parameters for frequency stitching in UWB detection in fields of bits of variable quantities. Frequency stitching may involve combining a number of consecutive channels (approximately four channels of up to 2 GHz) to perform UWB detection and is optional for UWB detection (therefore, the frequency stitching parameter presence field may be excluded from the detection control information element (514) for detection operations without frequency stitching). For example, the frequency stitching parameter presence field may include a field (902) indicating a base channel number or a channel number. Additionally or alternatively, the frequency stitching parameter presence field may indicate a field (904) indicating a carrier frequency grid configuration ID, a field (906) indicating an aggregated bandwidth associated with frequency stitching, and a field (908) containing one or more reserved bits for future use.

[0096] Using frequency stitching, wireless devices may be allowed to have 25%, 50%, or 75% overlap configurations, which can be enabled by defining the carrier frequency grid identified in the field (904) as 124.8 MHz. Wireless devices may use a single configuration method for both overlapped and non-overlapping carrier frequency grids. For example, carrier frequency configuration ID 0 may indicate no overlap, carrier frequency configuration ID 1 may indicate a 124.8 MHz carrier frequency grid, carrier frequency configuration ID 2 may indicate a 249.6 MHz carrier frequency grid, and carrier frequency configuration ID 3 may indicate a 374.4 MHz carrier frequency grid. Additionally, for carrier frequency configuration IDs 0, 1, 2, and 3, the total bandwidth configuration (corresponding to the number of transmissions) may be 500 MHz, 1 GHz, 1.5 GHz, or 2 GHz, respectively.

[0097] FIG. 10 illustrates an example of a signal diagram (1000) that supports RF sensing control for a UWB system according to some aspects of the present disclosure. The signal diagram (1000) may be implemented to implement or facilitate the implementation of any one or more examples and aspects of WLAN (100), or examples (200, 300, 400) and diagrams (500, 600, 700, 800, or 900). For example, the signal diagram (1000) illustrates communication between a wireless device (502) and a wireless device (504), which may be examples of corresponding devices described herein. The wireless device (502) and the wireless device (504) may be examples of two STAs, two APs, or one STA and one AP. Additionally, the wireless device (502) may be an example of a controller (also referred to as an initiator in this specification), and the wireless device (504) may be an example of a controlled object (also referred to as a responder in this specification).

[0098] In the following description of the signal diagram (1000), operations may be performed (e.g., reporting or providing) in a different order than the illustrated order, or operations performed by exemplary devices may be performed in different orders or at different times. For example, certain operations may also be omitted from the signal diagram (1000), or other operations may be added to the signal diagram (1000). Additionally, some operations or signaling may be illustrated as occurring at different times for the purposes of discussion, but these operations may actually occur simultaneously.

[0099] In 1005, a wireless device (502) (e.g., a first wireless device, an initiator, a controller) may transmit a sensing session setup request frame to a wireless device (504) (e.g., a second wireless device, a transponder, a controlled device) indicating a set of parameters for one or more sensing instances (sensing rounds), wherein one or more sensing instances are associated with the operation of the wireless device (502) with at least one wireless device (504) (at least one transponder) in an ultra-wideband system.

[0100] In 1010, the wireless device (502) may transmit a sensing control information element to the wireless device (504) and for each of one or more sensing instances, at least including a common sensing control configuration and a CIR report configuration. The common sensing control configuration may include one or more parameters for configuring a specific sensing instance. For example, the common sensing control configuration may include, among other parameters, indicating whether the sensing operation is mono-static, bi-static, or multi-static, and whether the wireless device (504) (transmitter) is a transmitter or a receiver. The CIR report configuration may indicate one or more parameters for configuring a CIR report. For example, the CIR report configuration may indicate a CIR bitmap for determining which CIR measurements will be included in the CIR report or excluded from the CIR report. Additionally, the sensing control information element may include 1-bit fields indicating the presence of the common sensing control configuration and the CIR report configuration in the sensing control information element.

[0101] In 1015 and 1020, the wireless device (502) and the wireless device (504) may participate in one or more individual sensing operations during one or more sensing instances. For example, during each sensing instance, the wireless device (502) may transmit a physical layer packet (e.g., PPDU). The packet may be reflected from an object or target and received by the wireless device (504), which can measure the CIR.

[0102] In 1025, the wireless device (502) may receive a CIR report from the wireless device (504) according to the CIR report configuration. The CIR report may include, for example, CIR values ​​per detection instance based on a CIR bitmap. In some implementations, the wireless device (502) may transmit the CIR report as an over-the-air CIR report or a MAC layer management entity report.
