Abstract
Description
Wireless sensing method and device Technical Field
[0001] The embodiments of the present application relate to the field of communications, and more specifically, to a method and device for wireless sensing. Background Art
[0002] In the New Radio (NR) system, targets can be detected and estimated based on perception signals. The existence of the target can be determined, and information such as its speed, distance, and direction of arrival angle can be estimated. Specifically, the network needs to semi-statically configure the resource on which the perception receiver performs measurements in a time interval (gap). The perception receiver measures the perception signal based on the configured time interval (gap), and data cannot be sent or received during the time interval (gap). However, since the perception receiver does not know when the perception transmitter sends the perception signal, it can only assume that the perception receiver performs perception signal measurements at the corresponding time interval (gap) after receiving the semi-static time interval (gap) configuration sent by the network. This may result in additional power consumption at the perception receiver and also lead to throughput performance loss at the perception receiver.

[0061] To facilitate a better understanding of the embodiments of the present application, the network architecture related to the present application is described.
[0062] Figure 2 is a schematic diagram of a network architecture provided by an embodiment of the present application. As shown in Figure 2, the 5G network architecture released by the 3rd Generation Partnership Project (3GPP) standard group includes:
[0063] Terminal equipment (UE), access network supporting 3GPP technology (including radio access network, RAN or access network, AN), user plane function (UPF) network element, access and mobility management function (AMF) network element, session management function (SMF) network element, policy control function (PCF) network element, application function (AF) network element, data network (DN) network element, network slice selection function (NSSF) network element, authentication server function (AUSF) network element, unified data management function (UDM) network element.
[0064] Those skilled in the art will appreciate that the 5G network architecture shown in FIG2 does not constitute a limitation on the 5G network architecture. In specific implementations, the 5G network architecture may include more or fewer network elements than shown, or may combine certain network elements. It should be understood that in FIG2, the AN or RAN is represented by (R)AN.
[0065] Access network equipment is the device that allows UEs to access the network architecture wirelessly. It is primarily responsible for radio resource management, quality of service (QoS) management, data compression, and encryption on the air interface side. Examples include NodeBs, evolved eNodeBs, base stations in 5G mobile communication systems or new radio (NR) communication systems, and base stations in future mobile communication systems.
[0066] The UPF, AMF, SMF, and PCF network elements are the network elements of the 3GPP core network (referred to as core network elements). The UPF network element can be called the user plane function network element, which is mainly responsible for the transmission of user data. The other network elements can be called the control plane function network elements, which are mainly responsible for authentication, authorization, registration management, session management, mobility management, and policy control to ensure the reliable and stable transmission of user data.
[0067] The UPF network element can be used to forward and receive data from the terminal. For example, the UPF network element can receive service data from the data network and transmit it to the terminal through the access network device; the UPF network element can also receive user data from the terminal through the access network device and forward it to the data network. Among them, the transmission resources allocated and scheduled by the UPF network element for the terminal are managed and controlled by the SMF network element. The bearer between the terminal and the UPF network element may include: the user plane connection between the UPF network element and the access network device, and the establishment of a channel between the access network device and the terminal. Among them, the user plane connection is a quality of service (QoS) flow that can be established between the UPF network element and the access network device to transmit data.
[0068] The AMF network element can be used to manage the terminal's access to the core network, such as terminal location update, network registration, access control, terminal mobility management, terminal attachment and detachment, etc. The AMF network element can also provide control plane storage resources for the session while providing services for the terminal's session, to store the session identifier, the SMF network element identifier associated with the session identifier, etc.
[0069] The SMF network element can be used to select a user plane network element for the terminal, redirect the user plane network element for the terminal, allocate an Internet Protocol (IP) address to the terminal, establish a bearer (also called a session) between the terminal and the UPF network element, modify and release the session, and control QoS.
[0070] The PCF network element is used to provide policies to the AMF network element and the SMF network element, such as QoS policy and slice selection policy.
[0071] The AF network element is used to interact with the 3GPP core network elements to support application-affected data routing, access network exposure functions, and interact with the PCF network elements for policy control.
[0072] DN network elements can provide data services to users on networks such as IP Multimedia Service (IMS) and the Internet. DNs can contain multiple application servers (ASs) that provide different application services, such as carrier services, Internet access, or third-party services. ASs can implement AF functions.
[0073] The NSSF network element is used for network slice selection and supports the following functions: selecting a set of network slice instances to serve the UE; determining the allowed network slice selection assistance information (NSSAI) and, when necessary, determining the mapping to the contracted single network slice selection assistance information (Single-Network Slice Selection Assistance Information, S-NSSAI); determining the configured NSSAI and, when necessary, determining the mapping to the contracted S-NSSAI; determining the set of AMFs that may be used to query the UE, or determining a list of candidate AMFs based on the configuration.
[0074] The AUSF network element is used to receive the request from the AMF to authenticate the terminal, request the key from the UDM, and then forward the issued key to the AMF for authentication processing.
[0075] UDM includes functions such as the generation and storage of user contract data, management of authentication data, and supports interaction with external third-party servers.
[0076] The network elements in Figure 2 can be network components in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (such as a cloud platform). It should be noted that the network architecture shown in Figure 2 is only an example of the network elements included in the entire network architecture. In the embodiments of the present application, the network elements included in the entire network architecture are not limited.
[0077] In order to facilitate a better understanding of the embodiments of the present application, the perceptions related to the present application are explained.
[0078] The radio electromagnetic wave signals used by cellular networks can not only be used for wireless data transmission and communication, but also have environmental perception capabilities, such as user motion or gesture recognition, breathing monitoring, terminal movement speed measurement, environmental imaging, and weather monitoring. With the official commercialization of fifth-generation mobile communication systems (5G) technology, communication is becoming possible not only between people but also between objects and between people. In Beyond 5G (B5G) / 6G, people are placing higher demands on end-to-end information processing capabilities, hoping to achieve mutual awareness of each other's status while communicating. This has led to the concept of integrated perception and communication. Communication signals sent by base stations or terminals are used to detect and estimate targets. While enabling communication, it is possible to determine the target's presence and estimate information such as its speed, distance, and direction of incoming waves. Therefore, in the future, cellular networks can be considered not only for communication and data transmission, but also for acquiring perception information.
[0079] Supporting perception capabilities in the B5G network can be achieved by adding a perception control network element or a perception function network element to the network architecture shown in Figure 2 and designing the corresponding perception process, thereby supporting the perception function in the 3GPP network. Specifically, Figure 3 is a flowchart of a possible control of the access network device or UE to perform UE-level perception operations. When the application sends a perception request for the target UE to the core network of the 3GPP network, the core network selects the correct access network device or auxiliary UE through the perception control network element or the AMF network element, and triggers the ability to perform perception-related wireless measurements, starts the measurement of the perception signal and generates the perception result.
[0080] The main wireless sensing modes of synaesthesia integration are as follows:
[0081] 1) Base station echo sensing (single gNB autonomous sensing): The base station sends a sensing signal and receives an echo signal.
[0082] 2) Inter-base station sensing (gNB-gNB sensing): Base station B receives the sensing signal sent by base station A;
[0083] 3) Air interface uplink perception (UE-gNB uplink perception): The base station receives the perception signal sent by the terminal;
[0084] 4) Air interface downlink perception (UE-gNB downlink perception): The terminal receives the perception signal sent by the base station;
[0085] 5) Terminal echo perception (single UE autonomous transmission and reception): The terminal sends a perception signal and receives an echo signal;
[0086] 6) Inter-terminal perception (UE-UE perception): Terminal B receives the perception signal sent by terminal A.
[0087] To facilitate a better understanding of the embodiments of the present application, the multi-point collaborative perception related to the present application is explained.
[0088] Communication and perception integration mainly uses the communication signals sent by base stations or terminals to detect and estimate targets. While being able to communicate, it can determine whether the target exists and estimate its speed, distance, incoming wave direction angle and other information.
[0089] Target perception through a single base station or terminal is subject to certain limitations. This is primarily due to the limited coverage of the base station or terminal, or the hardware processing capabilities of the base station or terminal. Furthermore, the complex mobile communication environment, with multipath and obstruction issues in signal propagation, can also affect perception performance.
[0090] Taking into account the networking characteristics of mobile communication networks, that is, the existence of multiple communication nodes and the ability for communication and collaboration between multiple nodes, it is possible to consider using multi-node collaboration in mobile communication networks to improve perception performance, including improving coverage and overcoming obstructions; saving network / terminal energy consumption; supporting mobility; improving perception accuracy; enhancing the integrity of perception information; and meeting diverse perception quality of service (QoS).
[0091] Multi-site cooperative sensing primarily studies how multiple sensing nodes (base stations or UEs) collaborate to improve sensing performance. Multipoint refers to the presence of multiple sensing links, meaning at least multiple sensing signal transmitting nodes or multiple sensing signal receiving nodes. A single sensing link consisting of one transmitting node and one receiving node is not covered by multipoint cooperative sensing. As shown in Figure 4, although there are two signaling nodes, there is only one sensing link, which is single-site sensing. As shown in Figure 5, there are two sensing links, which represents a multipoint sensing mode, or multipoint cooperative sensing.
[0092] To facilitate a better understanding of the embodiments of the present application, the sidelink (SL) transmission related to the present application is explained.
[0093] The vehicle-to-everything (V2X) system is a SL transmission technology based on device-to-device (D2D) communication. Unlike traditional NR systems where communication data is received or sent by base stations, the communication data in the V2X system uses direct terminal-to-terminal communication, resulting in higher spectrum efficiency and lower transmission latency.
[0094] The transmission of communication data requires time-frequency resources to carry it. Therefore, how terminals determine reasonable time-frequency resources through resource allocation algorithms to avoid mutual interference is one of the important research topics of New Radio-Vehicle to Everything (NR-V2X). In NR-V2X, there are two resource allocation modes. One is that the terminal determines the transmission resources based on the network's scheduling or configuration, called Mode 1, which includes dynamic scheduling and side-by-side configuration authorization schemes. The other is that the terminal autonomously selects transmission resources from the network-configured or pre-configured resource pool, called Mode 2, which includes basic resource reservation, resource selection algorithms, and re-evaluation and resource pre-emption mechanisms.
[0095] For Mode 1, the sidelink transmission resources of the vehicle terminal are allocated by the base station, and the vehicle terminal transmits data on the sidelink based on the resources allocated by the base station. The base station can allocate resources for a single transmission to the terminal, or it can allocate resources for semi-static transmission to the terminal. Figure 6 shows the process of a dynamic resource allocation method, in which the network schedules sidelink transmission (such as the Physical Sidelink Shared Channel (PSSCH) or the Physical Sidelink Control Channel (PSCCH)), the receiver performs sidelink Hybrid Automatic Repeat reQuest (HARQ) feedback via the Physical Sidelink Feedback Channel (PSFCH), and the transmitter reports HARQ feedback to the network.
[0096] In Mode 2, the terminal relies on resource listening or random selection to select time-frequency resources from a network-configured or pre-configured resource pool for transmitting sidelink data. Therefore, Mode 2 resource allocation should more accurately be described as resource selection, as shown in Figure 7. The vehicle-mounted terminal obtains a set of available transmission resources from the resource pool by listening, and the terminal randomly selects a resource from this set to transmit sidelink data. Due to the periodic nature of services in the Internet of Vehicles system, the terminal typically adopts a semi-static transmission method. That is, once the terminal selects a transmission resource, it will continue to use this resource for multiple transmission cycles, thereby reducing the probability of resource reselection and resource conflicts. The terminal will carry information about the reserved resources for the next transmission in the control information of this transmission, so that other terminals can determine whether the resource is reserved and used by the user by detecting the user's control information, thereby reducing resource conflicts.
[0097] In LTE V2X, sidelink (SL) transmissions can use a dedicated carrier or share a carrier with the uplink (UL). When the SL and UL share a carrier, SL transmissions can only use uplink transmission resources, such as uplink subframes in a time division duplexing (TDD) system or uplink carriers in a frequency division duplexing (FDD) system. UL transmissions cannot use downlink resources to avoid interference with terminals.
[0098] In the NR system, NR-Uu supports a flexible time slot structure, that is, a time slot can include at least one of downlink symbols, uplink symbols and flexible symbols, and the number of downlink symbols, uplink symbols and flexible symbols is configurable. Among them, the flexible symbol represents an uncertain transmission direction. This can achieve more flexible scheduling and reduce the uplink or downlink transmission delay. In actual applications, the transmission direction represented by the flexible symbol can be changed through configuration information or downlink control information (Downlink Control Information, DCI). For example, the flexible symbol is changed to a downlink symbol through DCI, or the flexible symbol is changed to an uplink symbol through DCI. For another example, the transmission direction is implicitly determined by configuration information, for example, the transmission of the synchronization signal block (Synchronization Signal Block, SSB) is configured on the flexible symbol, then it can be determined that the flexible symbol represents the downlink transmission. When the sideline transmission system can share a carrier with the cellular system, the sideline transmission can only use the uplink transmission resources of the cellular system. In NR-V2X, it is supported to use part of the time domain symbols in the time slot for sidelink transmission, that is, part of the symbols in a time slot that are semi-statically configured as uplink are used for sidelink transmission. In addition, considering that automatic gain control (AGC) symbols and guard period (GP) symbols are required in sidelink transmission, if the number of uplink symbols available for sidelink transmission is small, after removing the AGC symbols and GP symbols, the remaining symbols may not be able to accommodate the PSSCH and the corresponding demodulation reference signal (DMRS). Therefore, the time domain symbols occupied by the sidelink transmission in NR-V2X are at least 7 (including GP symbols). When the sidelink transmission system uses a dedicated carrier, there is no problem of sharing transmission resources with other systems, and all symbols in the time slot can be configured to be used for sidelink transmission.
[0099] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.
[0100] As shown in Figure 4, the sensing transmitter (STx gNB) sends a sensing signal, and the sensing receiver (SRx UE) receives the reflected signal, which is the signal obtained by reflecting the sensing signal from the sensed object. The sensing receiver (SRx UE) needs to report the measured transmission signal to the network, and the network performs sensing calculations based on the collected measurement results. The sensing receiver (SRx UE) reports the measurement results according to relevant preparation criteria.
[0101] The network semi-statically configures the resource intervals (gap intervals) at which the SRx UE performs measurements. The SRx UE then measures transmitted signals based on these configured gaps. Since the SRx UE does not know when the STx gNB transmits sensing signals, it cannot perform sensing actions. Therefore, it assumes that the SRx UE performs transmit signal measurements during the corresponding gaps after receiving the semi-static gap configuration from the network. This semi-statically configured gap configuration causes the SRx UE to perform measurements, resulting in additional power consumption and throughput loss for the SRx UE (data cannot be sent or received during the gaps).
[0102] Based on the above problems, this application proposes a wireless perception solution, which introduces trigger information for perception measurement based on perception measurement configuration information, so that perception measurement can be performed at the appropriate time, reducing the power consumption of perception measurement and improving the throughput of the perception receiving end.
[0103] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.
[0104] FIG8 is a schematic flowchart of a wireless sensing method 200 according to an embodiment of the present application. As shown in FIG8 , the wireless sensing method 200 may include at least part of the following contents:
[0105] S210, the second communication device sends first information; wherein the first information includes triggering information for performing perception measurement based on perception measurement configuration information;
[0106] S220: The first communication device receives the first information.
[0107] In the embodiment of the present application, trigger information for performing perception measurement based on perception measurement configuration information is introduced, so that perception measurement can be performed at an appropriate time, which reduces the power consumption of perception measurement and improves the throughput of the perception receiving end.
[0108] In the embodiment of the present application, the perceived object may be a vehicle, pedestrian, equipment, object, etc., and what needs to be perceived is a certain feature of the perceived object, such as speed, direction, distance, etc.
[0109] In some embodiments, the first communication device may be a perception receiving end (i.e., a device that receives a perception signal). In the embodiments of the present application, the first communication device performs perception measurements, specifically, the perception measurements may be performed on the perception signal sent by the perception sending end, or on the reflection signal of the perception signal sent by the perception sending end by the perceived object.
[0110] In some embodiments, the second communication device may be a perception sending end (i.e., a device that sends a perception signal), or may not be a perception sending end (i.e., a device that sends a perception signal), and this embodiment of the present application does not limit this.
[0111] In the embodiment of the present application, the perception receiving end may also be referred to as a perception signal receiving end or a perception signal receiving device, and the perception sending end may also be referred to as a perception signal sending end or a perception signal sending device.
[0112] In some embodiments, the first communication device may be a terminal device, and the second communication device may be a network device.
[0113] In some embodiments, the first communication device may be a terminal device, and the second communication device may be another terminal device.
[0114] In some embodiments, the perception measurement configuration information may be information semi-statically configured by the network device. For example, the perception measurement configuration information may be semi-statically configured time interval (gap) information, whereby perception measurements may be performed within the time interval (gap), perception signals may be received within the time interval (gap), and data may not be sent or received within the time interval (gap).
[0115] In some embodiments, the sensing measurement configuration information includes at least one of the following: sensing reference signal configuration, a time interval (gap) that requires measurement, and specifically, within the time interval (gap), the sensing receiving end needs to disconnect current data transmission and reception (if any).
[0116] In some embodiments, the sensing transmitter can send the sensing signal based on certain conditions, such as based on a sensing service request at the application layer. The network configures the resources used by the sensing transmitter to send the sensing signal. In addition, the network device can also configure the sensing reference signal configuration and the transmission method of the sensing signal.
[0117] In some embodiments, the perception reference signal may be a physical layer reference signal. Optionally, the perception reference signal includes, but is not limited to, at least one of the following: a channel state information reference signal (CSI-RS), a downlink positioning reference signal (DL PRS), a positioning sounding reference signal (SRS), and a sidelink positioning reference signal (SL PRS).
[0118] In some embodiments, the perception reference signal may be a reference signal specifically designed for perception. Optionally, the perception reference signal may include, but is not limited to, at least one of the following: a frequency modulation continuous wave (FMCW), a linear frequency modulation signal or a chirp signal, or an orthogonal time-frequency space (OTFS).
[0119] In an embodiment of the present application, after the first communication device (such as the perception receiving end) receives the perception measurement configuration information, in order to ensure the data transmission and reception performance of the first communication device (such as the perception receiving end) (frequent measurements will result in frequent interruptions of data transmission and reception) and save power consumption as much as possible (frequent measurements will result in reduced power consumption), it is assumed that the first communication device (such as the perception receiving end) does not start the corresponding perception measurement, that is, it only receives the perception measurement configuration information but does not immediately perform the perception measurement according to the perception measurement configuration information.
[0120] In some embodiments, the first information is carried through layer 1 or layer 2 signaling, for example, the first information is carried through downlink control information (DCI) or a media access control control element (MAC CE).
[0121] In some embodiments, the trigger information is used to instruct the first communications device to perform relevant information of the perception measurement.
[0122] In some embodiments, the trigger information is used to instruct the first communications device whether to perform perception measurement.
[0123] In some embodiments, when the trigger information is used to instruct the first communications device to perform perception measurements, the trigger information is further used to instruct or configure at least one of the following:
[0124] The starting time information of the perception measurement, the starting conditions of the perception measurement, the duration information of the perception measurement, the stopping time information of the perception measurement, the stopping conditions of the perception measurement, and the number of perception measurements.
[0125] In some embodiments, when the trigger information is used to instruct the first communications device to perform perception measurement, the trigger signal is further used to activate a timer associated with the perception measurement, or the trigger signal is further used to activate measurement criteria associated with the perception measurement.
[0126] In some embodiments, the timer is agreed upon by a protocol, or the timer is configured by a network device. Optionally, the timer is semi-statically configured by the network device, or the timer is dynamically configured by the network device. For example, the network device configures the timer via Radio Resource Control (RRC).
[0127] In some embodiments, the measurement rule is agreed upon by a protocol, or the measurement rule is configured by a network device. Optionally, the measurement rule is semi-statically configured by the network device, or the measurement rule is dynamically configured by the network device. For example, the network device configures the measurement rule via RRC.
[0128] In some embodiments, when the trigger information is also used to activate a timer associated with the perception measurement, the first communication device performs the perception measurement according to the perception measurement configuration information within the effective time of the timer, and the first communication device stops measuring the perception signal after the timer expires or the first communication device stops performing the perception measurement when the timer times out.
[0129] In some embodiments, the timer starts when the first communication device receives the first information, or the timer starts before the first time interval to be measured configured by the perception measurement configuration information, or the timer starts within a first time period after the first communication device receives the first information.
[0130] In some embodiments, the first duration is agreed upon by a protocol, or the first duration is indicated or configured by the trigger information.
[0131] In some embodiments, the measurement rules include:
[0132] The first communications device starts a perception measurement at a first time interval to be measured configured in the perception measurement configuration information, and stops the perception measurement after performing M measurements, where M is a positive integer; or
[0133] If the first perception measurement strength is not reached after N consecutive measurements based on the perception measurement configuration information, the first communication device stops performing the perception measurement, where N is a positive integer.
[0134] In some embodiments, the first perception measurement strength is agreed upon by a protocol, or the first perception measurement strength is indicated or configured by the trigger information.
[0135] In some embodiments, the trigger information is determined based on at least one of the following:
[0136] The timing of sending the perception signal, the time-frequency resources occupied by the perception signal, and the related configuration of the perception reference signal.
[0137] Specifically, the second communication device may determine the trigger information based on at least one of a sending timing of the perception signal, a time-frequency resource occupied by the perception signal, and a related configuration of the perception reference signal.
[0138] In some embodiments, the first information is a perception trigger signal, that is, the second communication device can be a perception trigger device. In other words, the perception trigger device sends a perception trigger signal, wherein the perception trigger signal includes trigger information for performing perception measurement based on perception measurement configuration information.
[0139] In some embodiments, when the first information is a perception trigger signal, before sending the first information, the second communication device receives second information, wherein the second information is used to indicate at least one of the following: a timing for sending the perception signal, time-frequency resources occupied by the perception signal, and a related configuration of a perception reference signal; and the second communication device determines the trigger information based on the second information.
[0140] In some embodiments, the second information is directly sent by the device that sends the perception signal, or the second information is sent by the device that sends the perception signal through a third communication device.
[0141] For example, the second communication device (such as a base station) sends a perception trigger signal, and the perception sending end (another base station or UE) sends a perception signal. That is, if the perception trigger signal and the sending node of the perception signal are not the same node, the two nodes need to interact with certain information (such as the sending timing of the perception signal, the time-frequency resources occupied by the perception signal, the relevant configuration of the perception reference signal, etc.), so that the second communication device can start the measurement of the perception signal according to the perception trigger signal before the perception sending end sends the perception signal. Among them, the information of different nodes (such as the sending timing of the perception signal, the time-frequency resources occupied by the perception signal, the relevant configuration of the perception reference signal, etc.) can be exchanged directly between the two nodes, or can be centrally coordinated and controlled by a network in the network.
[0142] In some embodiments, the first information is a perception signal, that is, the second communication device may be a perception sending end. In other words, the perception sending end sends a perception signal, wherein the perception signal includes triggering information for performing perception measurement based on perception measurement configuration information.
[0143] For example, the trigger information and the perception signal both come from the same node, such as the same base station or UE. In this scenario, the trigger information and the perception signal are combined into one message. That is, the perception transmitter does not need to send the trigger information and the perception signal separately. Upon receiving this message, the perception receiver measures the perception signal according to the instructions in the trigger information, such as starting or stopping the measurement of the perception signal.
[0144] In some embodiments, the first information is perception measurement configuration information, that is, the second communication device may be a network device. In other words, the network device sends perception measurement configuration information, wherein the perception measurement configuration information includes triggering information for performing perception measurement based on the perception measurement configuration information.
[0145] For example, the trigger information received by the first communication device (perception receiving end) may also come from network configuration information, such as contained in perception measurement configuration information. The perception measurement configuration information itself is trigger information. When the first communication device receives the perception measurement configuration information, it starts the perception signal measurement, and the corresponding measurement behavior (number of measurements, duration, etc.) is determined by the perception measurement configuration information. In this implementation, the first communication device cannot know when the perception sending end initiates the transmission of the perception signal. The first communication device only needs to start / stop the measurement of the potential perception signal according to the perception measurement configuration information.
[0146] Therefore, in an embodiment of the present application, trigger information for performing perception measurement based on perception measurement configuration information is introduced, so that perception measurement can be performed at an appropriate time, reducing power consumption of perception measurement and improving throughput of the perception receiving end.
