[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to and the benefit of Greek Patent Application No. 20210100173, entitled “BEAM-SPECIFIC MOTION STATE DETECTION CONFIGURATION AND REPORTING,” filed on March 18, 2021, which is assigned to the assignee of the present application and is expressly incorporated herein by reference in its entirety.

[0002] The subject matter disclosed herein relates to user equipment motion state detection, and more particularly, to determining and reporting user equipment motion state based on beam-specific information. [Background technology]

[0003] Motion state information of a user equipment (UE), such as a cellular phone, may be useful or necessary for several applications, including navigation, direction finding, cell selection, and asset tracking. The motion of the UE may be determined based on information collected from various systems. For example, a radio detection and ranging (RADAR, also called radar or radar) system may be used to determine the motion state of the device based on a radio frequency (RF) signal reflected by the device. In a wireless network (e.g., a cellular network implemented according to 4G (also called fourth generation) Long Term Evolution (LTE) radio access or 5G (also called fifth generation) "New Radio" (NR)), a base station may transmit an RF signal used for radar, the RF signal may be reflected by the UE, and the reflected signal may be received by the base station. Information about the reflection may be compared with information about the originally transmitted RF signal to determine the motion state of the UE. Improvements in determining and reporting motion state information are desirable. Summary of the Invention [Means for solving the problem]

[0004] A base station or other device configured for beamforming transmits RF signals along a transmit beam and receives RF signals along a receive beam. Each beam has an orientation associated with the device, and the RF signals along the beam travel to and from the device along a direction associated with the orientation of the beam. A device supporting motion detection services transmits a reference signal for radar along one or more transmit beams, and reflections of the reference signal are acquired by the device or another device along one or more receive beams. A motion state metric is determined based on the acquired reflections, and the motion state metric is reported to a radar server of the wireless network to determine the motion state of the UE. The reflected radar reference signal is received along one or more receive beams or initially transmitted along one or more transmit beams, and the motion state metric is associated with the receive beam or transmit beam. The device's reporting of the motion state metric, or the radar server's determination of the motion state from the motion state metric, is based on the receive beam or transmit beam.

[0005] In one implementation, a method for supporting motion detection services in a wireless network includes obtaining one or more reflections of a signal transmitted by a first device, the signal being associated with one or more beams of the first device, determining one or more motion state metrics based on the one or more reflections, and providing a motion state report to a network entity in the wireless network, the motion state report including the one or more motion state metrics.

[0006] In one implementation, a device configured to support a motion detection service in a wireless network includes at least one transceiver, at least one memory, and at least one processor coupled to the at least one transceiver and the at least one memory. The at least one processor is configured to cause the device to obtain, via the at least one transceiver, one or more reflections of a signal transmitted by a first device, where the signal is associated with one or more beams of the first device, determine, via the at least one processor, one or more motion state metrics based on the one or more reflections, and provide, via the at least one transceiver, a motion state report to a network entity in the wireless network. The motion state report includes the one or more motion state metrics.

[0007] In one implementation, a non-transitory computer-readable medium stores instructions that, when executed by at least one processor of a device configured to support motion detection services in a wireless network, cause the device to obtain, via the at least one transceiver, one or more reflections of a signal transmitted by a first device, where the signal is associated with one or more beams of the first device, determine, via the at least one processor, one or more motion state metrics based on the one or more reflections, and provide, via the at least one transceiver, a motion state report to a network entity in the wireless network, the motion state report including the one or more motion state metrics.

[0008] In one implementation, a device for supporting motion detection services in a wireless network includes means for obtaining one or more reflections of a signal transmitted by a first device, the signal being associated with one or more beams of the first device, means for determining one or more motion state metrics based on the one or more reflections, and means for providing a motion state report to a network entity in the wireless network, the motion state report including the one or more motion state metrics.

[0012] Aspects of the present disclosure are provided in the following description and associated drawings, which are directed to various examples provided for illustrative purposes. Alternative aspects may be devised without departing from the scope of the present disclosure. Additionally, well-known elements of the present disclosure will not be described in detail or will be omitted so as not to obscure the relevant details of the present disclosure.

[0013] The words "exemplary" and / or "example" are used herein to mean "serving as an example, instance, or illustration." Any aspect described herein as "exemplary" and / or "example" should not necessarily be construed as preferred or advantageous over other aspects. Similarly, the term "aspects of the present disclosure" does not require that all aspects of the present disclosure include the described feature, advantage or mode of operation.

[0014] Those skilled in the art will appreciate that the information and signals described below may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referred to throughout the following description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof, depending in part on the particular application, in part on the desired design, in part on the corresponding technology, etc.

[0015] Further, many aspects are described in terms of sequences of actions to be performed, for example, by elements of a computing device. It will be recognized that the various actions described herein can be performed by specific circuitry (e.g., an application specific integrated circuit (ASIC)), by program instructions being executed by one or more processors, or by a combination of both. Additionally, the sequences of actions described herein can be considered to be fully embodied in any form of non-transitory computer-readable storage medium storing a corresponding set of computer instructions that, when executed, will cause or instruct the associated processor of the device to perform the functionality described herein. Thus, various aspects of the present disclosure may be embodied in a number of different forms, all of which are contemplated to be within the scope of the claimed subject matter. In addition, for each of the aspects described herein, the corresponding form of any such aspect may be described herein, for example, as "logic configured to" perform the described actions.

[0016] The terms "user equipment (UE)" and "base station" as used herein are not intended to be specific or otherwise limited to any particular radio access technology (RAT) unless otherwise stated. In general, a UE may be any wireless communication device (e.g., a mobile phone, a router, a tablet computer, a laptop computer, a tracking device, a wearable (e.g., a smart watch, smart glasses, an augmented reality (AR) / virtual reality (VR) headset, etc.), a vehicle (e.g., an automobile, a motorcycle, a bicycle, etc.), an Internet of Things (IoT) device, etc.) used by a user to communicate over a wireless communication network. A UE may be mobile or may be stationary (e.g., at some times) and may communicate with a radio access network (RAN). The term "UE" as used herein may be referred to interchangeably as an "access terminal" or "AT", "client device", "wireless device", "subscriber device", "subscriber terminal", "subscriber station", "user terminal" or UT, "mobile terminal", "mobile station", "mobile device", or variations thereof. In general, a UE may communicate with a core network via a RAN, through which the UE may be connected to external networks, such as the Internet, and to other UEs. Of course, other mechanisms for connecting to the core network and / or the Internet are also possible for a UE, such as via a wired access network, a Wireless Local Area Network (WLAN) network (e.g., based on IEEE 802.11, etc.), etc.

[0017] A base station may operate according to one of several RATs in communication with a UE depending on the network in which the base station is deployed and may alternatively be referred to as an access point (AP), network node, Node B, evolved Node B (eNB), New Radio (NR) Node B (also referred to as gNB), etc. Additionally, in some systems, the base station may simply provide edge node signaling functionality, while in other systems, the base station may provide additional control and / or network management functionality. A communication link through which a UE may send signals to a base station is referred to as an uplink (UL) channel (e.g., reverse traffic channel, reverse control channel, access channel, etc.). A communication link through which a base station may send signals to a UE is referred to as a downlink (DL) or forward link channel (e.g., paging channel, control channel, broadcast channel, forward traffic channel, etc.). A communication link through which a UE signals to another UE is referred to as a sidelink (SL) or sidelink channel. As used herein, the term Traffic Channel (TCH) can refer to either a UL / reverse traffic channel, a DL / forward traffic channel, or a SL traffic channel.

[0018] The term "base station" may refer to a single physical transmit / receive point (TRP), sometimes referred to as a transmit / receive point, or multiple physical TRPs that may or may not be collocated. For example, when the term "base station" refers to a single physical TRP, the physical TRP may be an antenna of the base station corresponding to a cell of the base station. When the term "base station" refers to multiple collocated physical TRPs, the physical TRP may be an array of antennas of the base station (e.g., as in a multiple-input multiple-output (MIMO) system or when the base station employs beamforming). When the term "base station" refers to multiple non-collocated physical TRPs, the physical TRPs may be a distributed antenna system (DAS) (a network of spatially separated antennas connected to a common source via a transport medium) or a remote radio head (RRH) (a remote base station connected to a serving base station). Alternatively, the non-collocated physical TRPs may be a serving base station that receives measurement reports from the UE and a neighboring base station whose reference radio frequency (RF) signal the UE is measuring.

[0019] Radar solutions for motion detection may be specified in the 3rd Generation Partnership Project (3GPP®) set of standards for LTE (4G) and New Radio (NR) for fifth generation (5G), the Institute of Electrical and Electronics Engineers (IEEE) set of standards for wireless local area networks (WLANs), or other standardization bodies for wireless communications. Radar solutions may employ a radar server to support determining a motion state of a UE in a wireless network (e.g., a cellular network). The radar server may be part of or accessible from a serving network or a home network for the UE, or may simply be accessible via the Internet or via a local intranet. When motion detection services of the UE are required, the radar server may indicate the RF signals to be used for motion detection and the motion state metrics to be determined and provided to the radar server. The radar server may also track motion state information obtained for the UE in the wireless network, which may be used for cell selection, positioning, or other services of the wireless network for the UE. Although the radar server is described as performing certain operations, such operations may be performed by any suitable network entity (such as a core network device, a base station, a location server, or other suitable device of a wireless network).

[0020] The radar server (or other suitable network entity) and the base station (e.g., gNodeB (gNB)) may exchange messages to (i) configure the base station or UE to transmit signals defined for motion detection, (ii) configure the base station or UE to receive reflections of the transmitted signals, (iii) configure the base station or UE to generate motion state metrics from the received reflections, and (iv) enable the radar server (or other suitable network entity) to obtain the motion state metrics from the base station (which may be determined by the base station or obtained from the UE).

[0021] Base stations in a wireless network may be configured for beamforming. In this way, the transmit or receive beams of the base station are focused in a general direction to the base station. Focusing the beams allows the range in the direction to the device to be increased without increasing the power of the transmitted signal. Radar signals may be transmitted along one or more transmit beams, or reflections of the radar signals may be received along one or more receive beams for motion detection services. When reflections of signals are received along multiple receive beams, or the received reflections are from signals transmitted along multiple transmit beams, differences in orientation between the beams may cause differences in the motion measurements between the beams. For example, when determining the motion measurements includes measuring a phase difference between an originally transmitted signal and a reflected signal obtained, the phase difference for signals transmitted or received along a beam substantially parallel to the UE's axis of movement is greater than the phase difference for signals transmitted or received along a beam substantially perpendicular to the UE's axis of movement. In another example, a beam oriented to one side of a device may not include a transmitted signal or a received signal reflected by an object if the object is located on the other side of the device. Multiple motion state metrics associated with different beams may be used by a network entity (e.g., a radar server) to determine the overall motion state of the UE.

[0022] An extension of measuring and reporting motion state metrics in the presence of beamforming is desirable. As mentioned above, one of the limitations in motion detection services in the presence of beamforming is the variation of motion measurements based on different beams. For example, depending on which transmit beam transmits the original signal or which receive beam receives the reflection, the reflection may have a different phase or may be received at a different time.

[0023] Thus, as described herein, an extension is described for determining motion state metrics and reporting motion state metrics for a network entity (e.g., a radar server) to determine an overall motion state of a UE. In one implementation, a device acquires one or more reflections of a signal transmitted by a first device. The first device may be a base station (such as a gNB) or a UE that transmits a radar reference signal determined by the network entity (e.g., a radar server) to be used to determine the motion state of the UE. The device acquiring the reflections may be a base station, a UE, or a neighboring UE. If the first device is a base station, the reflections may be from the UE. If the first device is a UE, the reflections may be from objects in the UE's environment. The device acquiring the one or more reflections determines one or more motion state metrics (such as an indication of a phase difference associated with an originally transmitted signal and the acquired reflections as defined by the network entity (e.g., a radar server)) associated with one or more beams of the first device. If the device and the first device are the same device (such as a base station or UE that both transmits signals and obtains reflections), the one or more beams may include one or more transmit beams, or the one or more beams may include one or more receive beams. The device also provides a motion state report to a network entity in the wireless network. If the device is a base station, the network entity may be a radar server or another component of a core network communicatively coupled to the radar server. If the device is a UE or a neighboring UE, the network entity may be a base station or a relay UE. A suitable network entity of the wireless network (e.g., a radar server) determines the motion state of the UE based on one or more motion state metrics included in the motion state report.The motion state may include an indication of the location of the UE, the speed, velocity, or other degree of motion of the UE, or a range of motion associated with the UE (such as ranges of "no motion," "slow motion," or "fast motion" based on thresholds associated with the degree of motion and the range of motion).

[0024] 1 illustrates an exemplary wireless communication system 100. The wireless communication system 100 (which may also be referred to as a wireless wide area network (WWAN) or a wireless network (e.g., a cellular network)) may include various base stations 102, which may be referred to herein as gNBs 102 or other types of NBs, and various UEs 104. The base stations 102 may include macrocell base stations (high-power wireless base stations) and / or small cell base stations (low-power wireless base stations). In an aspect, the macrocell base stations may include eNBs, where the wireless communication system 100 corresponds to an LTE network, or gNBs, where the wireless communication system 100 corresponds to a 5G network, or a combination of both, and the small cell base stations may include femtocells, picocells, microcells, etc.

[0025] The base stations 102 may collectively form a RAN and may interface with a core network 170 (e.g., Evolved Packet Core (EPC) or Next Generation Core (NGC)) through the backhaul links 122, and with one or more radar servers 172 through the core network 170. In addition to other functions, the base stations 102 may perform functions related to one or more of forwarding user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection setup and release, load balancing, distribution for non-access stratum (NAS) messages, NAS node selection, synchronization, RAN sharing, Multimedia Broadcast Multicast Services (MBMS), subscriber and equipment tracking, RAN Information Management (RIM), paging, positioning, and distribution of alert messages. The base stations 102 may communicate with each other directly or indirectly (e.g., through EPC / NGC) via backhaul links 134, which may be wired or wireless.

[0026] The base stations 102 may wirelessly communicate with the UEs 104. Each of the base stations 102 may provide communication coverage to a respective geographic coverage area 110. In an aspect, one or more cells may be supported by the base station 102 in each coverage area 110. A "cell" is a logical communication entity used for communication with a base station (e.g., over some frequency resources called a carrier frequency, component carrier, carrier, band, etc.) and may be associated with an identifier (e.g., physical cell identifier (PCID), virtual cell identifier (VCID)) to distinguish cells operating over the same or different carrier frequencies. In some cases, different cells may be configured according to different protocol types (e.g., machine type communication (MTC), narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB), or others) that may provide access for different types of UEs. In some cases, the term "cell" may also refer to a geographic coverage area (eg, a sector) of a base station, so long as the carrier frequency is detectable and usable for communication within some portion of the geographic coverage area 110.

[0027] The geographic coverage areas 110 of neighboring macrocell base stations 102 may overlap partially (e.g., in handover regions), but some of the geographic coverage areas 110 may be significantly overlapped by larger geographic coverage areas 110. For example, a small cell base station 102' may have a coverage area 110' that significantly overlaps with the coverage area 110 of one or more macrocell base stations 102. A network that includes both small cell base stations and macrocell base stations may be referred to as a heterogeneous network. A heterogeneous network may also include a Home eNB (HeNB), which may serve a restricted group called a Closed Subscriber Group (CSG).

[0028] The communication link 120 between the base station 102 and the UE 104 may include UL (also referred to as reverse link) transmissions from the UE 104 to the base station 102, and / or downlink (DL) (also referred to as forward link) transmissions from the base station 102 to the UE 104. The communication link 120 may use MIMO antenna techniques, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link 120 may be over one or more carrier frequencies. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​than UL).

[0029] The small cell base station 102' may operate in a licensed and / or unlicensed frequency spectrum. When operating in an unlicensed frequency spectrum, the small cell base station 102' may employ LTE or 5G technology and may use the same 5 GHz unlicensed frequency spectrum used by WLAN APs. A small cell base station 102' employing LTE / 5G in an unlicensed frequency spectrum may extend coverage to and / or increase capacity of an access network. LTE in an unlicensed spectrum may be referred to as LTE Unlicensed (LTE-U), Licensed Assisted Access (LAA), or MulteFire.

[0030] The wireless communication system 100 may further include a mmW base station 180 that may operate in millimeter wave (mmW) and / or sub-mmW frequencies in communication with the UE 182. Extremely High Frequency (EHF) is a portion of RF in the electromagnetic spectrum. EHF has a range of 30 GHz to 300 GHz and a wavelength between 1 millimeter and 10 millimeters. Radio waves in this band may be referred to as millimeter waves. Sub-mmW may extend down to frequencies of 3 GHz with wavelengths of 100 millimeters. The Super High Frequency (SHF) band extends between 3 GHz and 30 GHz and is also referred to as centimeter waves. Communications using mmW / sub-mmW radio frequency bands have high path losses and relatively short distances. The mmW base station 180 and the UE 182 may utilize beamforming (transmit and / or receive) over the mmW communication link 184 to compensate for the extremely high path losses and short distances. It will be appreciated that in alternative configurations, one or more base stations 102 may also transmit using mmW or sub-mmW and beamforming. Therefore, it should be appreciated that the above illustrations are merely illustrative and should not be construed as limiting the various aspects disclosed herein.

[0031] Transmit beamforming is a technique for focusing an RF signal in a particular direction. Traditionally, when a network node (e.g., a base station) broadcasts an RF signal, it broadcasts it in all directions (omnidirectionally). With transmit beamforming, the network node determines where a given target device (e.g., UE) is located (relative to the transmitting network node) and projects a stronger downlink RF signal in that particular direction, thereby providing a faster and more powerful RF signal (in terms of data rate) to the receiving device. To vary the directionality of the RF signal when transmitting, the network node can control the phase and relative amplitude of the RF signal at each of one or more transmitters broadcasting the RF signal. For example, the network node may use an array of antennas (called a "phased array" or "antenna array") that creates beams of RF waves that can be "steered" to point in different directions without actually moving the antennas. In particular, RF current from a transmitter is fed to each antenna with the proper phase relationship so that the radio waves from the separate antennas add together to enhance radiation in the desired direction while canceling out radiation in undesirable directions.

[0032] In receive beamforming, a receiver uses receive beams to amplify RF signals detected on a given channel. For example, the receiver can increase the gain setting and / or adjust the phase setting of an array of antennas in a particular direction to amplify (e.g., increase the gain level of) the RF signals received from that direction. Thus, when a receiver is said to beamform in some direction, it means that the beam gain in that direction is larger than the beam gains along other directions, or that the beam gain in that direction is the largest compared to the beam gains in that direction of all other receive beams available to the receiver. This results in a stronger received signal strength (e.g., Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference and Noise Ratio (SINR), etc.) of the RF signals received from that direction.

[0033] In 5G, the frequency spectrum in which the wireless nodes (e.g., base station 102 / 180, UE 104 / 182) operate is divided into multiple frequency ranges, namely, FR1 (450 MHz to 6000 MHz), FR2 (24250 MHz to 52600 MHz), FR3 (above 52600 MHz), and FR4 (between FR1 and FR2). In a multi-carrier system such as 5G, one of the carrier frequencies is called the "primary carrier" or "anchor carrier" or "primary serving cell" or "PCell", and the remaining carrier frequencies are called the "secondary carrier" or "secondary serving cell" or "SCell". In carrier aggregation, the anchor carrier is the carrier that operates on the primary frequency (e.g., FR1) utilized by the UE 104 / 182 and on the cell in which the UE 104 / 182 either performs an initial radio resource control (RRC) connection establishment procedure or initiates an RRC connection re-establishment procedure. The primary carrier carries all common and UE-specific control channels. The secondary carrier is a carrier operating on a second frequency (e.g., FR2) that may be configured once an RRC connection is established between the UE 104 and the anchor carrier and may be used to provide additional radio resources. Since both the primary uplink carrier and the primary downlink carrier are typically UE-specific, the secondary carrier may contain only the necessary signaling information and signals, e.g., signaling information and signals that are UE-specific may not be present in the secondary carrier. This means that different UEs 104 / 182 in a cell may have different downlink primary carriers. The same applies to the uplink primary carrier. The network can change the primary carrier of any UE 104 / 182 at any time. This is done, for example, to balance the load on different carriers.Since a "serving cell" (whether a PCell or an SCell) corresponds to a carrier frequency / component carrier over which several base stations are communicating, terms such as "cell", "serving cell", "component carrier", and "carrier frequency" can be used interchangeably.

[0034] For example, still referring to FIG. 1, one of the frequencies utilized by the macrocell base station 102 may be an anchor carrier (or, "PCell"), and the other frequencies utilized by the macrocell base station 102 and / or the mmW base station 180 may be secondary carriers ("SCells"). Simultaneous transmission and / or reception of multiple carriers allows the UE 104 / 182 to significantly increase its data transmission and / or reception rates. For example, two aggregated 20 MHz carriers in a multi-carrier system would theoretically lead to a two-fold increase in data rate (i.e., 40 MHz) compared to the data rate achieved by a single 20 MHz carrier.

[0035] The wireless communication system 100 may further include one or more UEs that indirectly connect to one or more communication networks via one or more device-to-device (D2D) peer-to-peer (P2P) links. In the example of FIG. 1, the UE 164 has a D2D P2P link 192 with one of the UEs 104 connected to one of the base stations 102. The link 192 may be used to indirectly obtain wireless connectivity for D2D communication between the UEs 104 and 164 without using the base station 102. In some implementations, the link 192 is a sidelink (SL) between the UEs 104 and 164. In one example, the D2D P2P link 192 may be supported with any well-known D2D RAT, such as LTE Direct (LTE-D), WiFi Direct (WiFi-D), Bluetooth®, etc.

[0036] The wireless communications system 100 may include a UE 164, which may communicate with a macrocell base station 102 via communications link 120 and / or with an mmW base station 180 via an mmW communications link 184. For example, the macrocell base station 102 may support a PCell and one or more SCells for the UE 164, and the mmW base station 180 may support one or more SCells for the UE 164.

[0037] The radar server 172 may include one or more radar servers that will configure the wireless network to support motion detection services based on radar technology. The radar server 172 determines which signal resources will be used for radar, and the radar server 172 indicates to the base station 102 (and via the base station to the UE) the signal resources to be used. As used herein, a signal resource may be any suitable frequency or time domain portion of a signal. A signal for radar may include any suitable reference signal (RS) or data signal. In some implementations, the radar server 172 determines one or more radar RS resources to include one or more of a DL channel state information RS (DL-CSI-RS), a DL positioning reference signal (DL-PRS, which may be indicated by a location server coupled to the core network 170), a synchronization signal block (SSB, each SSB is associated with a particular transmission beam of the base station transmitting the radar RS), a UE-to-UE SL-SSB (each SL-SSB is associated with a particular transmission beam of the UE transmitting the radar RS), a SL-CSI-RS, or a SL-PRS. The radar server 172 also determines and manages motion state information for one or more UEs 104 in the wireless network 100. For example, motion state metrics for the UEs 104 are reported to the radar server 172 by the base stations 102 via the core network 170. The radar server 172 may determine or store a motion state for the UE 104 from the obtained motion state metrics. The motion state may be any suitable indication of the UE's motion. As mentioned above, the motion state may include speed, velocity, acceleration, or another suitable indication of motion. The motion state may include a value to indicate a range of motion or a particular amount of motion. The motion state may be used to configure cell selection, handover, beamforming, positioning, or other aspects of the wireless network 100. The radar server 172 also indicates what motion state metrics are to be reported to the radar server 172.As mentioned above, although operations herein are described as being performed by radar server 172 for clarity, one or more operations may be performed by another suitable network entity (such as a base station, a location server, or another suitable network entity). Thus, radar server as used herein may refer to any suitable network entity for performing the described operations.

[0038] 2 shows a block diagram of a design 200 of a base station 102 and a UE 104, which may be one of the base stations and one of the UEs in FIG. 1. Design 200 shows communication between a base station 102 and a UE 104 for the following illustrated example in describing aspects of the disclosure, although the communication may be between two UEs 104 over an SL (such as a UE communicating with a relay UE), two base stations 102, or other devices in wireless network 100. With reference to design 200, base station 102 may be equipped with T antennas 234a-t and UE 104 may be equipped with R antennas 252a-r, where in general T≧1 and R≧1.

[0039] In the base station 102, the transmit processor 220 may receive data for one or more UEs from a data source 212, may select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, may process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and may provide data symbols to all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, higher layer signaling, etc.) and may provide overhead and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively. According to various aspects described in more detail below, synchronization signals can be generated using location coding to convey additional information.

[0040] At the UE 104, the antennas 252a-252r may receive downlink signals from the base station 102 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a-254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a-254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols and may provide decoded data for the UE 104 to a data sink 260 and may provide decoded control and system information to the controller / processor 280. The channel processor may determine a reference signal received power (RSRP), a received signal strength indicator (RSSI), a reference signal received quality (RSRQ), a channel quality indicator (CQI), etc. In some aspects, one or more components of the UE 104 may be included within a housing.

[0041] On the uplink, at the UE 104, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, CQI, etc.) from the controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a-254r, and transmitted to the base station 102. At the base station 102, uplink signals from the UE 104 and other UEs may be received by the antennas 234, processed by a demodulator 232, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by the UE 104. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to the controller / processor 240. The base station 102 may include a communication unit 244 via which it may communicate to other devices (such as core network components).

[0042] The controller / processor 240 of the base station 102, the controller / processor 280 of the UE 104, and / or any other components of FIG. 2 may perform one or more techniques related to performing motion detection services, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 102, the controller / processor 280 of the UE 104, and / or any other components of FIG. 2 may perform or direct operations of, for example, the illustrated and / or described processes and / or other processes as described herein. The memory 242 and the memory 282 may store data and program codes for the base station 102 and the UE 104, respectively. In some aspects, the memory 242 and / or the memory 282 may comprise a non-transitory computer-readable medium that stores one or more instructions for wireless communication. For example, the one or more instructions, when executed by one or more processors of the base station 102 and / or the UE 104, may perform or direct operations of a process as described herein. The scheduler 246 may schedule the UE for data transmission on the downlink and / or uplink. In some implementations, the scheduler may be used by the UE 104 for data transmission on the sidelink.

[0043] As noted above, Figure 2 is provided as an example. Other examples may differ from those described with respect to Figure 2 (such as communications between two UEs or other types of devices in a wireless network).

[0044] In the frequency domain for uplink, downlink, or sidelink transmission, the available bandwidth may be divided into uniformly spaced orthogonal subcarriers (also called "tones" or "bins"). For example, for a regular length cyclic prefix (CP) using 15 kHz spacing, the subcarriers may be grouped into groups of 12 subcarriers. A resource of one OFDM symbol length in the time domain and one subcarrier in the frequency domain is called a resource element (RE). Each grouping of 12 subcarriers and 14 OFDM symbols is called a resource block (RB), and in the above example, the number of subcarriers in a resource block is:

[0045]

number

[0046] For a given channel bandwidth, the number of available resource blocks on each channel, also called the transmission bandwidth configuration, may be written as:

[0047]

number

[0048] For example, for a 3 MHz channel bandwidth in the above example, the number of available resource blocks on each channel is

[0049]

number

[0050] It should be noted that a frequency component of a resource block (eg, 12 subcarriers) is called a physical resource block (PRB).

[0051] A collection of resource elements used for a radar-based motion detection service may be referred to as a “radar resource.” When the resource elements are from one or more reference signals, the collection of resource elements may be referred to as a “radar RS resource.” A collection of resource elements may span multiple PRBs in the frequency domain and one or more symbols within or across a slot in the time domain. A base station or a UE may transmit a radar resource (such as a radar RS resource) for use in a motion detection service. For example, an indication of one or more radar RS resources to be used may be received at a communication unit 244 of the base station 102 from a radar server 172. In some implementations, the base station 102 may configure itself to transmit one or more radar RS resources over a downlink. In some implementations, the base station 102 may indicate one or more radar RS resources to one or more UEs 104, which may transmit one or more radar RS resources over a sidelink.

[0052] 3 illustrates a UE 300, an example of a UE 104 capable of supporting motion detection services in a wireless network (such as the cellular network 100). For example, the UE 300 may be configured to transmit and / or receive one or more radar RS resources and / or generate one or more motion state metrics to be reported to the radar server 172. The UE 300 includes a computing platform including at least one processor 310, a memory 311 including software (SW) 312, one or more sensors 313, a transceiver interface 314 for a transceiver 315, a user interface 316, and a camera 318. The processor 310, the memory 311, the sensor 313, the transceiver interface 314, the user interface 316, and the camera 318 may be communicatively coupled to each other by a bus 320 (which may be configured for optical and / or electrical communication, for example). One or more of the illustrated devices (e.g., camera 318, and / or one or more of sensors 313, etc.) may be omitted from UE 300, or UE 300 may include additional devices (e.g., a positioning system receiver (such as a Global Navigation Satellite System (GNSS) or Global Positioning System (GPS) receiver and processing components) that are not illustrated. Processor 310 may include one or more intelligent hardware devices, e.g., a central processing unit (CPU), a microcontroller, an application specific integrated circuit (ASIC), etc. Processor 310 may comprise multiple processors, including application processor 330, digital signal processor (DSP) 331, modem processor 332, video processor 333, and / or sensor processor 334. One or more of processors 330-334 may comprise multiple devices (e.g., multiple processors). For example, sensor processor 334 may comprise a processor for, e.g., radar, ultrasonic, and / or lidar, etc. The modem processor 332 may support dual SIM / dual connectivity (and even more SIMs).For example, one SIM (Subscriber Identity Module or Subscriber Identification Module) may be used by an original equipment manufacturer (OEM) and another SIM may be used by an end user of the UE 300 for connectivity. The memory 311 is a non-transitory storage medium that may include random access memory (RAM), flash memory, disk memory, and / or read-only memory (ROM), etc. The memory 311 stores the software 312, which may be processor-readable processor-executable software code including instructions that, when executed, are configured to cause the processor 310 to operate as a special-purpose computer programmed to perform various functions described herein. Alternatively, the software 312 may not be directly executable by the processor 310, but may be configured, for example, when compiled and executed, to cause the processor 310 to operate as a special-purpose computer to perform various functions described herein. Although the description may only refer to the processor 310 performing functions, this includes other implementations, such as when the processor 310 executes software and / or firmware. The description may refer to the processor 310 performing a function as shorthand for one or more of the processors 330-334 performing the function. The description may refer to the UE 300 performing a function as shorthand for one or more suitable components of the UE 300 performing the function. The processor 310 may include a memory having stored instructions in addition to and / or in place of the memory 311. The functionality of the processor 310 is described more fully below.

[0053] The configuration of UE 300 shown in FIG. 3 is an example and not a limitation of the present disclosure, including the claims, and other configurations may be used. For example, an exemplary configuration of a UE includes one or more of processors 330-334 of processor 310, memory 311, and wireless transceiver 340. Other exemplary configurations include one or more of processors 330-334 of processor 310, memory 311, and wireless transceiver 340, as well as one or more of sensors 313, user interface 316, camera 318, and / or wired transceiver 350.

[0054] The UE 300 may include a modem processor 332 that may be capable of performing baseband processing of signals received and downconverted by the transceiver 315. The modem processor 332 may perform baseband processing of signals to be upconverted for transmission by the transceiver 315. Also or alternatively, the baseband processing may be performed by the processor 330 and / or the DSP 331, although other configurations may be used to perform the baseband processing.

[0055] The UE 300 may include sensors 313, which may include one or more of various types of sensors, such as, for example, one or more inertial sensors, one or more barometric sensors, one or more magnetometers, one or more environmental sensors, one or more optical sensors, one or more weight sensors, and / or one or more radio frequency (RF) sensors. An inertial measurement unit (IMU) may comprise, for example, one or more accelerometers (e.g., collectively responsive to acceleration of the UE 300 in three dimensions) and / or one or more gyroscopes capable of detecting motion, including rotation, of the UE 300. The sensors 313 may include one or more magnetometers for determining orientation (e.g., relative to magnetic north and / or true north), which may be used for any of a variety of purposes, for example, to support one or more compass applications. The environmental sensors may include, for example, one or more temperature sensors, one or more barometric pressure sensors, one or more ambient light sensors, one or more camera imagers, and / or one or more microphones, etc. The sensors 313 may generate analog and / or digital signals, representations of which may be stored in memory 311 and processed by the DSP 331 and / or the processor 330, for example, in support of one or more applications, such as applications directed to positioning and / or navigation operations.

[0056] The sensors 313 may be used in relative location measurements, relative location determination, motion determination, and the like. Information detected by the sensors 313 may be used for motion detection, relative displacement, dead reckoning, sensor-based location determination, and / or sensor-assisted location determination. The IMU may be configured to provide measurements on the direction of motion and / or speed of motion of the UE 300, which measurements may be used in relative location determination. For example, one or more accelerometers and / or one or more gyroscopes of the IMU may detect linear acceleration and rotational velocity of the UE 300, respectively. The linear acceleration and rotational velocity measurements of the UE 300 may be integrated over time to determine an instantaneous direction of motion and displacement of the UE 300. The instantaneous direction and displacement of motion may be integrated to track the location of the UE 300. For example, a reference location of UE300 may be determined for a certain moment in time, and measurements from the accelerometer and gyroscope taken after this moment in time may be used in dead reckoning to determine the current location of UE300 based on the movement (direction and distance) of UE300 relative to the reference location.

[0057] The magnetometer may determine magnetic field strength in different directions, which may be used to determine an orientation of the UE 300. For example, the orientation may be used to provide a digital compass for the UE 300. The magnetometer may be a two-dimensional magnetometer configured to detect and provide an indication of magnetic field strength in two orthogonal dimensions. Alternatively, the magnetometer may be a three-dimensional magnetometer configured to detect and provide an indication of magnetic field strength in three orthogonal dimensions. The magnetometer may provide a means for sensing the magnetic field and providing an indication of the magnetic field, for example, to the processor 310.

[0058] The air pressure sensor may determine air pressure, which may be used to determine the UE 300's altitude within a building or current floor level. For example, differential pressure readings may be used to detect when the UE 300 changes floor levels, as well as the number of floors that are being changed. The air pressure sensor may provide a means for sensing air pressure and providing an indication of the air pressure, for example, to the processor 310.

[0059] The transceiver 315 may include a wireless transceiver 340 and a wired transceiver 350 configured to communicate with other devices over wireless and wired connections, respectively. For example, the wireless transceiver 340 may include a transmitter 342 and a receiver 344 coupled to one or more antennas 346 to transmit (e.g., on one or more uplink channels and / or one or more sidelink channels) and / or receive (e.g., on one or more downlink channels and / or one or more sidelink channels) wireless signals 348 and convert signals from the wireless signals 348 to wired (e.g., electrical and / or optical) signals and from the wired (e.g., electrical and / or optical) signals to the wireless signals 348. Thus, the transmitter 342 may include multiple transmitters, which may be separate or combined / integrated components, and / or the receiver 344 may include multiple receivers, which may be separate or combined / integrated components. The wireless transceiver 340 may be configured to communicate signals (e.g., with a base station and / or one or more other devices) according to various radio access technologies (RATs), such as 5G New Radio (NR), Global System for Mobiles (GSM), Universal Mobile Telecommunications System (UMTS), Advanced Mobile Phone System (AMPS), Code Division Multiple Access (CDMA), Wideband CDMA (WCDMA), Long Term Evolution (LTE), LTE Direct (LTE-D), 6GPP LTE-V2X (PC5), IEEE 802.11 (including IEEE 802.11p), WiFi, WiFi Direct (WiFi-D), Bluetooth, Zigbee, etc. The New Radio may use mm-wave and / or sub-6 GHz frequencies. The wired transceiver 350 may include a transmitter 352 and a receiver 354 configured for wired communication. The transmitter 352 may include multiple transmitters, which may be separate components or combined / integrated components, and / or the receiver 354 may include multiple receivers, which may be separate components or combined / integrated components.The wired transceiver 350 may be configured for optical and / or electrical communication, for example. The transceiver 315 may be communicatively coupled to the transceiver interface 314, for example, by an optical and / or electrical connection. The transceiver interface 314 may be at least partially integrated with the transceiver 315. In some implementations, the transceiver 315 does not include the wired transceiver 350.

[0060] The antenna 346 may include an antenna array, which may be capable of receive beamforming or transmit beamforming, for example, by increasing the gain setting and / or adjusting the phase setting of the array of antennas in a particular direction to amplify (e.g., to increase the gain level) an RF signal received from or transmitted toward that direction. The antenna 346 may further include multiple antenna panels, each capable of beamforming. The antenna 346 may be adapted, for example, to select one or more antennas to control receiving a beam transmitted from a base station or another UE or transmitting a beam toward a base station or another UE. For example, to reduce power consumption, a reduced number of beams or a single beam may be selected, for example, for receiving a wide beam, and an increased number of antennas in the antenna array may be selected when the transmit beam is relatively narrow. Conversely, the antenna 346 may be configured to transmit a wide beam or a relatively narrow beam.

[0061] The user interface 316 may comprise one or more of several devices, such as, for example, a speaker, a microphone, a display device, a vibrating device, a keyboard, a touch screen, etc. The user interface 316 may include any two or more of these devices. The user interface 316 may be configured to allow a user to interact with one or more applications hosted by the UE 300. For example, the user interface 316 may store in the memory 311 a representation of an analog and / or digital signal to be processed by the DSP 331 and / or the processor 330 in response to an action from the user. Similarly, an application hosted on the UE 300 may store in the memory 311 a representation of an analog and / or digital signal to present an output signal to the user. The user interface 316 may include audio input / output (I / O) devices, such as, for example, a speaker, a microphone, digital-to-analog circuitry, analog-to-digital circuitry, an amplifier, and / or gain control circuitry (including any two or more of these devices). Other configurations of audio I / O devices may be used. Additionally or alternatively, the user interface 316 may include one or more touch sensors that respond to contact and / or pressure, for example, on a keyboard and / or touch screen of the user interface 316 .

[0062] The UE 300 may include a camera 318 for capturing still or video images. The camera 318 may comprise, for example, an imaging sensor (e.g., a charge-coupled device or CMOS imager), a lens, analog-digital circuitry, a frame buffer, etc. Additional processing, conditioning, encoding, and / or compression of signals representing the captured images may be performed by the general-purpose processor 330 and / or the DSP 331. Also or alternatively, conditioning, encoding, compression, and / or manipulation of signals representing the captured images may be performed by a video processor 333. The video processor 333 may decode / decompress stored image data, for example, for presentation on a display device (not shown) of the user interface 316.

[0063] The memory 311 may store software 312, including executable program code or software instructions that, when executed by the processor 310, may cause the processor 310 to operate as a special-purpose computer programmed to perform the functions disclosed herein. As illustrated, the memory 311 may include one or more components or modules that may be implemented by the processor 310 to perform the functions disclosed. Although the components or modules are illustrated as software 312 in the memory 311 executable by the processor 310, it should be understood that the components or modules may be stored in another computer-readable medium or may be dedicated hardware either within the processor 310 or external to the processor. Several software modules and data tables may reside in the memory 311 and be utilized by the processor 310 to manage both the communications and functionality described herein. It should be appreciated that the organization of the contents of the memory 311 as illustrated is only an example, and thus the functionality of the modules and / or data structures may be combined, separated, and / or structured in different ways depending on the implementation.

[0064] The memory 311 may include a motion detection (MD) module 372 that, for example, when implemented by the one or more processors 310, configures the one or more processors 310 to participate in a motion detection session for a UE in a wireless network, e.g., the motion of the UE 300 or the motion of a neighboring UE, as described herein. For example, the one or more processors 310 may be configured to participate in the MD session by performing one or more of: transmitting one or more radar RS resources via one or more transmit beams, receiving reflections of the one or more radar RS resources via one or more receive beams, measuring UE motion information (e.g., the motion of the UE 300 or the motion of a neighboring UE) based on the received reflections, generating a motion status report including one or more motion status metrics based on the measured motion information, or transmitting the motion status report to a base station (e.g., a gNB) or relay UE (with the report ultimately provided to a radar server coupled to the core network). Although the MD session module 372 is shown as being software contained within memory 311, the MD session module 372 may be a hardware module, a software module, or a combination of hardware and software. For example, a module may include one or more application specific integrated circuits (ASICs), executable code, or a combination of both.

The base station 400 includes a computing platform including at least one processor 410, a memory 411 including software (SW) 412, and a transceiver 415. The processor 410, the memory 411, and the transceiver 415 may be communicatively coupled to each other by a bus 420 (e.g., may be configured for optical and / or electrical communication). One or more of the illustrated devices may be omitted from the base station 400, or the base station 400 may include one or more devices not illustrated. The processor 410 may include one or more intelligent hardware devices, such as a central processing unit (CPU), a microcontroller, an application specific integrated circuit (ASIC), etc. The processor 410 may comprise multiple processors (e.g., including one or more of an application processor, a DSP, a modem processor, a video processor, and / or a sensor processor, similar to those illustrated in FIG. 3). The memory 411 is a non-transitory storage medium that may include random access memory (RAM), flash memory, disk memory, and / or read-only memory (ROM), etc. The memory 411 stores the software 412, which may be processor-readable, processor-executable software code that includes instructions that, when executed, are configured to cause the processor 410 to operate as a special-purpose computer programmed to perform various functions described herein. Alternatively, the software 412 may not be directly executable by the processor 410, but may be configured, for example, when compiled and executed, to cause the processor 410 to operate as a special-purpose computer to perform various functions described herein.

The processor 410 may include memory having stored instructions in addition to and / or in place of the memory 411. The functionality of the processor 410 is described more fully below.

[0066] The transceiver 415 may include a wireless transceiver 440 and a wired transceiver 450 configured to communicate with other devices over wireless and wired connections, respectively. For example, the wireless transceiver 440 may include a transmitter 442 and a receiver 444 coupled to one or more antennas 446 to transmit and / or receive wireless signals 448 (e.g., on one or more uplink channels and / or one or more downlink channels) and convert signals from the wireless signals 448 to wired (e.g., electrical and / or optical) signals and from the wired (e.g., electrical and / or optical) signals to the wireless signals 448. The antenna 446 is one or more antenna arrays capable of beamforming and transmitting and receiving beams, including beams used in transmitting or receiving signals (including radar RS resources) to support motion state detection of UEs in a wireless network. The transmitter 442 may include multiple transmitters, which may be separate components or combined / integrated components, and / or the receiver 444 may include multiple receivers, which may be separate components or combined / integrated components. The wireless transceiver 440 may be configured to communicate signals (e.g., with the UE 300, one or more other UEs, and / or one or more other devices) according to various radio access technologies (RATs), such as 5G New Radio (NR), GSM (Global System for Mobile), UMTS (Universal Mobile Telecommunications System), AMPS (Advanced Mobile Phone System), CDMA (Code Division Multiple Access), WCDMA (Wideband CDMA), LTE (Long Term Evolution), LTE Direct (LTE-D), 6GPP LTE-V2X (PC5), IEEE 802.11 (including IEEE 802.11p), WiFi, WiFi Direct (WiFi-D), Bluetooth, Zigbee, etc. The wired transceiver 450 may include a transmitter 452 and a receiver 454 configured for wired communication, for example, to send communications to the radar server 172 and receive communications from the radar server 172.The transmitter 452 may include multiple transmitters, which may be separate components or combined / integrated components, and / or the receiver 454 may include multiple receivers, which may be separate components or combined / integrated components. The wired transceiver 450 may be configured for optical and / or electrical communications, for example.

[0067] 4 is an example and not a limitation of the present disclosure, including the claims, and other configurations may be used. For example, the description herein describes the base station 400 as being configured to or performing certain functions, but one or more of these functions may be performed by the radar server 172 and / or the UE 300.

[0068] The memory 411 may store software 412, including executable program code or software instructions that, when executed by the processor 410, may cause the processor 410 to operate as a special-purpose computer programmed to perform the functions disclosed herein. As illustrated, the memory 411 may include one or more components or modules that may be implemented by the processor 410 to perform the functions disclosed. Although the components or modules are illustrated as software 412 in the memory 411 executable by the processor 410, it should be understood that the components or modules may be stored in another computer-readable medium or may be dedicated hardware either within the processor 410 or external to the processor. Several software modules and data tables may reside in the memory 411 and be utilized by the processor 410 to manage both the communications and functionality described herein. It should be appreciated that the organization of the contents of the memory 411 as illustrated is only an example, and thus the functionality of the modules and / or data structures may be combined, separated, and / or structured in different ways depending on the implementation.

[0069] The memory 411 may include a motion detection (MD) session module 472 that, for example, when implemented by the processor 410, configures the processor 410 to engage in a motion detection session for the UE as described herein. For example, the one or more processors 410 may configure the base station 400 to indicate to one or more UEs 104 one or more radar RS resources to be used for motion state detection, to transmit resources, to transmit one or more radar RS resources, to receive reflections of the one or more radar RS resources, to determine one or more motion measurements of the UE based on the reflections, to generate a motion state report including one or more motion state metrics based on the one or more motion measurements, to provide a report to the radar server 172 (e.g., via one or more core network components), to obtain a report from the UE 104, to relay the obtained report to the radar server 172, or to generate an aggregate report from multiple reports or motion state metrics provided to the radar server 172. Although the MD session module 472 is shown as being software contained within memory 411, the MD session module 472 may be a hardware module, a software module, or a combination of hardware and software. For example, a module may include one or more application specific integrated circuits (ASICs), executable code, or a combination of both.

[0070] With regard to radar-based motion state metrics and motion state identification, a standalone radar system determines a phase offset between a transmitted radar signal and a received reflection of the radar signal. The phase offset (also called phase difference) is related to the round trip time (RTT) of the radar signal and indicates the depth of the object from the transmitter and receiver. The multiple depths over time indicate the motion state of the object (such as speed, velocity, or other suitable degree of motion). Due to phase corruption from sampling frequency offset (SFO), carrier frequency offset (CFO), or random timing synchronization errors from devices in the wireless network 100, it may be difficult to determine the phase offset using a single chain device in the wireless network 100 (such as one chain of base stations 104 or UEs 102 separately). To compensate for the corruption in determining the phase offset based on a single chain, other chains of the multi-chain device may be used to determine the phase offset between the chains. Since the above corruption of the phase is common across all chains, the phase offset between the chains may be used to remove any corruption to the phase of a single chain.

[0071] To remove corruption to the phase exclusively in a single chain device (or without using other chains in a multi-chain device), a phase offset may be determined between adjacent tones. For example, one or more radar RS resources may be associated with a defined tone of the RS, and a phase offset between the defined tones (or other adjacent tones) in the RS may be determined. The phase offset between the tones may be used to remove any corruption to the phase of a single chain for a radar RS resource, since the above corruption of phase affects the tones as well. A motion state based on measurements between tones may be based on comparing a baseline (BL) measurement of the tone with a motion detection (MD) measurement of the tone. A BL measurement refers to measuring the phase of the tone when the environment of the device performing the measurement is static (no movement around the device). A MD measurement refers to measuring the phase of the tone during when a motion state is to be identified. Note that the phase may refer to the phase of the channel frequency response (CFR). The motion state may be for the device itself or for a UE in the device's environment.

[0072] In one example of calculating BL measurements for an exemplary array of tones [t1, tN], a phase array for multiple packets of a signal including tones [tone(1), tone(N)] is determined for multiple sensing packets. The phase array for the i-th sensing packet in a moving window over the sensing packets is shown below in equation (1). Δij = |phase(tone(j))-phase(tone(j+1))|, for integer j ∈ [1,N-1], PA(i)=[Δi1,Δi2,...,Δi(N-1)] (1)

[0073] The BL metric g may be the average of the phase array over the sensing packet, as shown in equation (2) below.

[0074]

number

[0075] However, M BL is the number of sensing packets used for the BL measurement.

[0076] For the MD measurement of objects based on the BL metric g, a certain number M MD In one example of calculating the MD measurement value, the MD metric f(t) is the average of the phase array over the sensing packets for the MD measurement, as shown in equation (3) below:

[0077]

number

[0078] The motion state (sometimes called the motion degree) may be the distance between the BL metric g and the MD metric f(t). For example, the mean square error (MSE) may be determined between the metrics, as shown in Equation (4) below.

[0079]

number

[0080] The motion degree is an indication of the motion of the UE (such as the speed of the UE), with a higher number indicating a higher speed of the UE. In this manner, the device obtains radar RS resource reflections, determines a motion degree based on the reflections, and determines a motion state metric based on the motion degree (the motion state metric is included in a report to the radar server 172). In some implementations, the motion degree is the motion state metric reported to the radar server 172. In this manner, the report includes the determined motion degree. In some implementations, the motion state metric is an indication that the motion degree is within a range of motion degrees. For example, a "no motion" range may be associated with a motion degree from 0 to a first threshold, a "slow motion" range may be associated with a motion degree from the first threshold to a second threshold, and a "fast motion" range may be associated with a motion degree from and beyond the second threshold. In this manner, the device compares the motion degree to a threshold associated with the range to identify a range, and the motion state metric is an indication of the identified range. Although phase difference is shown as an exemplary motion measurement, the device may determine other suitable motion measurements (such as timing difference or frequency offset), and the reported motion state metric or metrics may be based on the motion measurement or metrics. Exemplary motion state metrics may include or be indicative of one or more of a device Doppler shift measurement, a device Doppler spread measurement, a device speed measurement, or a device velocity measurement.

[0081] Types of radar systems include monostatic radar systems and multistatic radar systems. A monostatic radar system includes one device that both transmits radar signals and receives reflections of radar signals. A monostatic radar system may be for identifying a motion state of a transmitting / receiving device or for identifying objects in the environment of the transmitting / receiving device. A multistatic radar system includes a system having a receiving device different from the transmitting device. For example, one or more transmitting devices transmit radar signals and one or more separate receiving devices receive reflections of the radar signals from objects. An exemplary multistatic radar system is a bistatic radar system with one transmitting device transmitting and one receiving device receiving, although there may be any number of transmitting or receiving devices. A multistatic radar system may be for identifying a motion state of objects reflecting radar signals.

[0082] The wireless network 100 may be configured for monostatic radar and / or multistatic radar (such as bistatic radar). For a monostatic radar example, a base station 102 (such as a gNB) may be configured to transmit one or more radar RS resources indicated by a radar server 172 and receive reflections of the one or more radar RS resources. In another example, a UE 104 may be configured to transmit one or more radar RS resources indicated by a radar server 172 (which may be indicated to the UE 104 by a serving base station 102 to the UE 104) and receive reflections of the one or more radar RS resources. For a multistatic radar example, a base station 102 may transmit one or more radar RS resources and one or more UEs 104 or different base stations 102 may receive reflections of the one or more radar RS resources. For the illustrated example, the radar RS resources may be transmitted or received via a downlink, uplink, or sidelink for the device.

[0083] As the radar RS resources are indicated by the radar server 172, the radar RS resources are known across the transmitting and receiving devices used for motion detection services. With the radar RS resources to be used defined across the devices, the receiving device of the reflection can determine the motion measurements and motion status metrics of the motion status report to be provided to the radar server 172. The receiving device generates the motion status report and provides the report to a network entity (which may be the radar server 172 or a component communicatively coupled to the radar server 172, such as a base station, a relay UE, or a core network component). For example, if the receiving device is a UE 104, the report is provided by the UE 104 to the base station 102 (such as a gNB) during UL transmission or to the relay UE 104 during SL transmission (with the relay UE 104 providing the report to the base station 102). If the receiving device is a base station 102 (such as a gNB), the report is provided by the base station 102 to the radar server 172 or a core network component communicatively coupled to the radar server 172.

[0084] A transmitting device or a receiving device for a motion detection service in a wireless network may be configured for beamforming. For example, the antenna arrays 234a-234t may be configured for beamforming at the base station 102, and / or the antenna arrays 252a-252r may be configured for beamforming at the UE 104. In this manner, one or more of the signals for the motion detection service (such as one or more radar RS resources) are transmitted via one or more transmit beams and / or received via one or more receive beams. The transmitted signal or the received reflection is associated with one or more transmit beams or receive beams, and the motion status metric determined by the receiving device is associated with one or more beams. For example, a set of radar RS resources may be transmitted via two different transmit beams. When the set of radar RS resources via the two different transmit beams is reflected by an object and received by the receiving device, the reflections associated with the different transmit beams may differ from each other based on being transmitted via the different transmit beams. Similarly, when the reflections are received via two different receive beams of the receiving device, the reflections associated with the different receive beams may differ from each other based on being received via the different receive beams.

[0085] FIG. 5 illustrates a flow chart for an example method 500 for supporting motion detection services in a wireless network. The example method 500 may be performed by any suitable device of a wireless network (e.g., a cellular network), such as the base station 102 or 400 shown in FIG. 1 and FIG. 4 or the UE 104 or 300 shown in FIG. 1 and FIG. 3, as well as the disclosed implementations. For example, a device that may perform one or more operations in the method 500 may include at least one transceiver (such as one or more wireless transceivers and / or one or more wired transceivers), at least one memory, and at least one processor coupled to the at least one transceiver and the at least one memory. Referring to the UE 300 as an example device, the at least one transceiver may include the transceiver 315 or the wireless transceiver 340, the at least one memory may include the memory 311, and the at least one processor may include the processor 310, or one or more of the processors 330-334. Referring to base station 400 as an exemplary device, the at least one transceiver may include a transceiver 415 or a wireless transceiver 440, the at least one memory may include a memory 411, and the at least one processor may include a processor 410.

[0086] In block 502, the device obtains one or more reflections of a signal transmitted by the first device, the signal being associated with one or more beams of the first device. The means for obtaining one or more reflections of the signal transmitted by the first device may include at least one transceiver (such as a wireless transceiver) of the device. As described above, the signal may be transmitted via one or more transmit beams of the first device. Also or alternatively, if the device performing the method 500 is a first device (such as a monostatic radar), the one or more reflections may be received via one or more receive beams. The one or more beams of the first device may include one or more transmit beams and / or one or more receive beams. The UE means for receiving one or more reflections may include a transceiver 315 and one or more processors 310 having dedicated hardware or implementing executable code or software instructions 312 in a memory 311, such as the MD session module 372 in the UE 300 shown in FIG. 3. The base station means for receiving one or more reflections may include a transceiver 415 and one or more processors 410 having dedicated hardware or implementing executable code or software instructions 412 in a memory 411, such as the MD session module 472 in the base station 400 shown in FIG. 4.

[0087] In block 504, the device determines one or more motion state metrics based on the one or more reflections. The means for determining one or more motion state metrics may include at least one processor of the device. The signal is associated with one or more beams of the first device, and one or more motion state metrics are associated with the one or more beams of the first device. The UE means for determining one or more motion state metrics may have dedicated hardware or include one or more processors 310 implementing executable code or software instructions 312 in memory 311, such as the MD session module 372 in the UE 300 shown in FIG. 3. The base station means for determining one or more motion state metrics may have dedicated hardware or include one or more processors 410 implementing executable code or software instructions 412 in memory 411, such as the MD session module 472 in the base station 400 shown in FIG. 4.

[0088] In block 506, the device provides a motion state report to a network entity in the wireless network. The means for providing the motion state report may include at least one transceiver of the device. The motion state report includes one or more motion state metrics. The UE means for providing the motion state report may include a transceiver 315 and one or more processors 310 having dedicated hardware or implementing executable code or software instructions 312 in memory 311, such as the MD session module 372 in the UE 300 shown in FIG. 3. The base station means for providing the motion state report may include a transceiver 415 and one or more processors 410 having dedicated hardware or implementing executable code or software instructions 412 in memory 411, such as the MD session module 472 in the base station 400 shown in FIG. 4. The motion state may be determined by a radar server 172 coupled to the core network 170 based on one or more motion state metrics obtained by the radar server 172. In some implementations, the motion state of the UE is based on one or more motion state metrics included in the motion state report.

[0089] In some implementations, if the beam or beams associated with the motion state metric or metrics include one or more receive beams, the motion state metric or metrics may be associated with measurements of quasi-co-location (QCL) information related to the one or more receive beams. For example, the motion state metric or metrics may be associated with QCL type D information measured from reflections. QCL information refers to characteristics of symbols or resources via one beam (which may be measured at a first set of antenna ports) that can be inferred from symbols or resources via the other beam (which may be measured at a second set of antenna ports). QCL type D information refers to spatial receive parameters as defined in Technical Specification (TS) 38.214 of Release 15 of the 3GPP® set of standards. Other parameters that may be related to the motion state metric may be associated with other types of QCL information (e.g., QCL type A, B, or C information, which may include Doppler shift, Doppler spread, or delay spread).

[0090] In some implementations, the propagation delay may be determined based on a known distance between the base station and the reference base station. For example, the known distance between the base station and the reference base station may be determined based on known positions of the base station and the reference base station. In another example, the base station may further perform a wireless ranging procedure involving the reference base station, and the known distance between the base station and the reference base station is determined based on the wireless ranging procedure.

[0091] In some implementations, a first device transmitting a signal may transmit one or more radar RS resources. If the one or more radar RS resources are transmitted via one or more transmit beams of the first device, each radar RS resource is associated with a particular transmit beam. For example, if the radar RS resources include DL-CSI-RS, the DL-CSI-RS may be transmitted using one, two, four, eight, or more orthogonal antenna ports of a base station configured for one or more transmit beams. If the radar RS resources include DL-PRS, the location server may indicate the transmit beam of the base station for transmitting the DL-PRS (wherein the base station may act as a transmit / receive point (TRP) for position location). If the radar RS resources include SSBs (such as DL-SSBs or SL-SSBs), each SSB is associated with a particular transmit beam. If the radar RS resources include SL-CSI-RS or SL-PRS, each may be associated with a transmit beam of the UE as described above with respect to DL-CSI-RS and DL-PRS, respectively. In this manner, the radar server 172 may indicate which radar RS resources are to be used, and a device receiving one or more reflections of the radar RS resources may determine which transmit beam to use in transmitting the radar RS resources based on the particular radar RS resources indicated. The indication from the radar server 172 may be provided to the device by any suitable device in the wireless network 100 (e.g., a base station 102 or relay UE 104 to another UE 104, or a core network component to the base station 102). In some implementations, the indication may include instructions to associate a set of radar RS resources with a particular transmit beam (based on a particular physical layer (PHY) channel or time window indicated by the radar server 172 or determined by the transmitting device as described herein, or an explicit transmit beam indicated in the instructions, etc.).It should be noted that the receiving device may determine one or more receive beams based on which antenna port receives one or more reflections of the radar RS resource.

[0092] Similarly or alternatively to a particular radar RS resource being associated with a particular transmit beam, the transmission on a particular transmit beam may be during a particular time window. For example, the transmission via one or more transmit beams may be time division multiplexed (TDM). The radar server 172 may indicate the time at which the radar RS resource is to be transmitted, which may be within a time window associated with the transmission via a particular transmit beam. In some implementations, the time may be within a time window associated with the receive beam of the receiving device. For the time domain window, any suitable type of signal or resource may be used for transmission, including a physical downlink shared channel (PDSCH), a physical downlink control channel (PDCCH), a physical sidelink shared channel (PSSCH), a physical sidelink control channel (PSCCH), a CSI-RS, a tracking reference signal (TRS), a synchronization signal block (SSB), a DL-PRS, a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), or a sounding RS (SRS). In some implementations, different slots may be associated with different beams and therefore different motion state metrics. For example, a first beam may be associated with a first set of one or more slots, and a second beam may be associated with a second set of one or more slots. The receiving device may determine a first motion state metric associated with the first set of one or more slots (associated with the first beam) and may determine a second motion state metric associated with the second set of one or more slots (associated with the second beam). In this manner, a time window may include multiple consecutive symbols of a transmitted or received signal. In some implementations, a time window may include multiple non-consecutive symbols within a slot of a transmitted or received signal (such as a first and second portion of a symbol of a slot separated by one or more symbols, where the first and second portions are transmitted via the same transmit beam).

[0093] The transmit beam may be associated with one or more physical layer (PHY) channels of the transmitting device. In this manner, different transmit beams may be associated with different PHY channels. The receiving device receives one or more reflections at one or more carrier frequencies. The one or more PHY channels of the transmitting device may be determined based on the one or more carrier frequencies, and the transmit beam may be determined based on the one or more PHY channels.

[0094] The motion state report may include one or more motion state metrics and an association of the motion state metrics to one or more beams. The association may include an indication of one or more receive beams (such as QCL type D information), an indication of one or more determined transmit beams, an indication of one or more radar RS resources measured in the reflection (which may indicate the transmit beam used), an indication of one or more time windows associated with the reflection (which may indicate the transmit beam used), an indication of one or more PHY channels (such as one or more carrier frequencies that identify channels associated with the transmit beam used), or any combination of the above indications. The association to one or more beams may include indicating a beam index for each associated beam.

[0095] As discussed above with respect to the phase offset for the motion measurements, determining the motion measurements of the UE may be based on BL measurements of radar RS resources during a time when the environment of the transmitting device and the environment of the receiving device are static. For example, reflections of a set of radar RS resources transmitted along a first beam may be received at the receiving device when the environment is static (which may be in a test environment or an environment being controlled to generate the BL motion measurements), and the BL motion measurements may be determined from the received reflections (such as the BL motion metric g as described above for a particular transmit beam). Thus, the BL motion measurements are associated with no motion occurring in the environment of the first device. When the motion state of the UE is to be determined, another set of radar RS resources may be transmitted along the first beam at a different time, and reflections may be received at the receiving device. The receiving device may determine a first motion measurement (such as the metric f(t) as described above for a particular transmit beam) based on the received reflections. The receiving device may then determine a difference between the BL motion measurement and the first motion measurement. The motion state metric in the report to the radar server 172 may be the difference associated with the particular transmit beam.

[0096] With respect to the motion measure with reference to the time window, the receiving device determining the motion measure may include measuring a variation in amplitude of the signal transmitted during the time window, measuring a variation in received signal strength (RSS) of the signal transmitted during the time window, measuring a variation in phase of the signal transmitted during the time window, determining a quantized channel Doppler response based on a measured Doppler shift from the signal transmitted during the time window, or any combination of the above.

[0097] In determining the one or more motion state metrics, the receiving device may determine one or more motion measurements and may determine one or more motion state metrics based on the one or more motion measurements. In some implementations, the motion state metric included in the report may be the motion measurement determined by the receiving device. For example, the determined motion degree (as shown in Equation 4 above) may be the determined motion measurement, and the motion state metric in the report may be the motion degree. In some implementations, the motion measurement may be compared to one or more thresholds, and the motion state metric is an indication of the comparison result. For example, the motion degree may be compared to thresholds associated with ranges of no motion, slow motion, and fast motion, as described above. The motion state metric of the report may indicate into which range the motion degree falls based on the comparison.

[0098] As described above, the motion state report may indicate an association of one or more motion state metrics to one or more transmit beams, one or more receive beams, one or more radar RS resources, one or more time windows, one or more PHY channels, or any combination of the above. If the indicated association is to one or more time windows, the association may be to a start time and an end time of a time window associated with a transmit beam (or a receive beam). If the association is to one or more PHY channels, the association may be to a start and an end of a frequency domain window for transmitting the radar RS resource. The association to one or more time windows may include a window identifier (ID). For example, the radar server 172 may indicate a time window using a window ID, with each of the one or more time windows being associated with a different window ID. As described above, each time window is associated with a transmit beam based on a configuration of the transmit resources of the transmitting device (e.g., a particular antenna port). The association indicated in the report may include a window ID.

[0099] Motion measurements and motion state metrics may be determined for a particular transmit or receive beam. In this manner, a first motion state metric may be determined for a first beam, and the first motion state report includes a first motion state metric associated with the first beam. In some implementations, a second motion state metric may be determined for a second beam. The first motion state report may be a joint report including a second motion state metric associated with the second beam. In some implementations of the joint report, the device may determine that the first motion state metric and the second motion state metric are included in the joint report. In some implementations of the joint report, the device may receive a motion state report from another device, and the device may include the motion state metric from the received motion state report in the joint report. For example, a relay UE or a base station (e.g., a gNB) may receive a report from one or more other UEs and may combine the motion state metric from the received report into a joint report (which may or may not include one or more motion state metrics determined by the device). In this manner, any number of motion state metrics from any number of devices may be included in a motion state report to the radar server 172. In some implementations of the integrated report, the motion state metric may be a statistical value related to the motion measurement. For example, an example motion state metric may include a motion measurement average, a motion measurement median, or another statistical value or distribution measured over multiple instances of the motion measurement (e.g., over different time instances). In some implementations of the integrated motion state report, the integrated motion state report may include multiple other motion state reports received from other devices and / or generated by the device generating the integrated motion state report.

[0100] Also or alternatively, the second motion state report may include a second motion state metric associated with the second beam. In this way, different motion state reports may be used to report motion state metrics associated with different beams. In some implementations, the motion state report or motion state metric may be used as a BL report or metric. Subsequent reports or metrics may indicate a difference from the BL. For the above example, the first motion state report includes the first motion state metric. The device generating the second motion state report may determine a difference between the first motion state metric and the second motion state metric, and the second motion state report may include the determined difference to indicate the second motion state metric. Also or alternatively, any other suitable indication of the motion state metric may be included in the motion state report.

[0101] A motion measure may be determined for a reflection associated with each of a plurality of transmit and / or receive beams. As a result, a plurality of motion measures are determined. The number of motion measures increases as the number of beams increases. Each beam is oriented in a unique manner with respect to the device. For example, a particular transmit beam may be associated with a particular direction of travel of a transmission via the transmit beam, and a particular receive beam may be associated with a particular direction of travel of a signal received via the receive beam. The motion measures associated with a particular beam are associated with the movement of an object along a direction associated with the beam. For example, a device may receive a first set of reflections of radar RS resources transmitted via a first transmit beam for a UE traveling along a direction that matches the orientation of the first transmit beam, and the device may receive a second set of reflections of radar RS resources transmitted via a second transmit beam for the UE (where the orientation of the second transmit beam is orthogonal to the UE's direction of travel rather than the orientation of the first transmit beam). The device may determine a first motion measure for the UE associated with the first transmit beam, and the device may determine a second motion measure for the UE associated with the second transmit beam. The first motion measurement is greater (such as a larger phase offset, a larger Doppler shift, or a larger Doppler spread) than the second motion measurement because the UE's motion is more consistent with the orientation of the first transmit beam than with the orientation of the second transmit beam. In this manner, the device may determine multiple motion measurements that vary based on the orientation of the beam associated with the motion measurement and the UE's motion being measured.

[0102] In some implementations, the device may filter one or more motion measurements from being used to generate a motion state metric, or the device may filter one or more motion state metrics from being included in a motion state report. For example, a motion state report may be specified to include a certain number of motion state metrics (such as one, two, four, or any other suitable number). The number of motion state metrics to be included may be indicated by the radar server 172. The device may include a motion state metric associated with a maximum motion measurement value (indicating a maximum motion of the UE in an associated direction) up to the number of motion state metrics in the report along with one or more associations (such as a beam index associated with each motion state metric). For example, if the motion state report is to include one motion state metric, the device may determine the motion state metric based on the maximum motion measurement value. In this manner, the motion state report includes the determined motion state metric for the maximum motion measurement value and an association to one or more parameters (e.g., a beam index for a transmit beam or a receive beam).

[0103] As mentioned above, the device performing method 500, including receiving the reflections, may be the same device that transmits (in the case of a monostatic radar system) or a different device from the device that transmits (in the case of a multistatic radar system). The receiving device may be a base station (e.g., a gNB) (which may be the same device that transmits). Also or alternatively, the receiving device may be a UE (which may be the same device or a different device from the transmitting device). If the receiving device is a UE, the UE may be measuring its own motion or may be measuring the motion of a neighboring UE. If the receiving device is a base station (e.g., a gNB), the base station (e.g., a gNB) may be measuring the motion of the UE.

[0104] One or more configurations for motion detection services, such as configurations of beam indexes, radar RS resources to measure, time domain windows to measure, or frequency bands to measure, may be indicated by the radar server 172 to the base station 102. The base station 102 may indicate the one or more configurations to one or more UEs 104 to perform operations for motion detection (such as transmitting or receiving radar RS resources). Transmission from the base station 102 to the UEs 104 may be via broadcast or groupcast messages (e.g., including a radar-specific system information block (SIB) or a positioning SIB containing radar-specific information), or any suitable unicast message.

[0105] The motion state metrics in one or more motion state reports may be used by the radar server 172 in any suitable manner. In some implementations, the motion state metrics may be used by the radar server 172 to determine a location or trajectory of the UE based on a beam associated with the motion state metrics. In some implementations, the motion state metrics may be used to determine candidate base stations 102 for handover or handover criteria, or to determine criteria for cell selection. The UE-specific information determined by the radar server 172 may also remain in the radar server 172 for later use in one or more wireless network operations.

[0107] Some portions of the detailed description contained herein are presented in terms of algorithms or symbolic representations of operations on binary digital signals stored in a memory of a specific apparatus or a dedicated computing device or platform. In the context of this particular specification, the term specific apparatus or the like includes a general purpose computer that, when programmed, should perform certain operations according to instructions from program software. Algorithmic descriptions or symbolic representations are examples of techniques used by those skilled in the signal processing or related arts to convey the substance of their work to others skilled in the art. An algorithm is here, and generally, considered to be a self-consistent sequence of operations or similar signal processing that leads to a desired result. In this context, operations or processing involve physical manipulations of physical quantities. Usually, but not necessarily, such quantities may take the form of electrical or magnetic signals that can be stored, transferred, combined, compared, or otherwise manipulated. It has proven convenient at times, primarily for reasons of common usage, to refer to such signals as bits, data, values, elements, symbols, characters, terms, numbers, values, or the like. It should be understood, however, that all of these or similar terms are to be associated with the appropriate physical quantities and are merely convenient labels. Unless otherwise indicated, and as will be apparent from the description herein, it will be appreciated that throughout this specification, descriptions utilizing terms such as "processing," "computing," "calculating," "determining," and the like refer to the actions or processes of a particular apparatus, such as a special purpose computer, a special purpose computing apparatus, or a similar special purpose electronic computing device.
