In the embodiment of the present application, only the core network device in the NR system is described as an example, and the specific type of the core network device is not limited.
For ease of understanding, some of the matters related to the embodiments of the present application are described below:
1. communication awareness integration (Integrated Sensing and Communication, ISAC).
Wireless Communication and radar Sensing (C & S) have been developed in parallel, but with limited intersections. They share much in terms of signal processing algorithms, devices, and to some extent system architecture. In recent years, conventional radars are moving toward more general wireless perception. Wireless perception may broadly refer to retrieving information from a received radio signal. For wireless sensing related to the sensing target position, dynamic parameters such as reflection delay, arrival angle, departure angle, doppler and the like of a target signal can be estimated through a common signal processing method; for sensing target physical characteristics, this can be achieved by measuring the natural signal pattern of the device/object/activity. The two sensing modes can be respectively called sensing parameter estimation and pattern recognition. In this sense, wireless sensing refers to more general sensing techniques and applications that use radio signals.
Communication awareness integration may also be referred to as universal awareness integration, ISAC has the potential to integrate wireless awareness into mobile networks, referred to herein as awareness mobile networks (Perceptive Mobile Networks, PMNs). Perceived mobile networks are capable of providing both communication and wireless perceived services and are expected to be a ubiquitous wireless sensing solution due to their large broadband coverage and powerful infrastructure. The perception mobile network can be widely applied to communication and sensing in the fields of traffic, communication, energy, precision agriculture and safety. The sensor network can also provide complementary sensing capability for the existing sensor network, has unique day and night operation function, and can penetrate fog, leaves and even solid objects.
Multiple-Input Multiple-Output (MIMO) radar and high-precision parameter estimation techniques.
MIMO radar can obtain higher detection/estimation resolution, higher maximum identifiable target number, and better clutter suppression capability relative to phased Array (Phase Array) using waveform diversity (Waveform Diversity) and Virtual Array (Virtual Array) characteristics. MIMO radars can be further classified into a centralized MIMO radar (Co-located MIMO Radar) and a distributed MIMO radar (Distributed MIMO Radar) according to antenna deployment locations. The MIMO radar virtual array principle is as follows. Considering the total number of the MIMO radar transmitting array antennas as M, and the position coordinates of each transmitting antenna as x T,m M=0, 1,..m-1, total number of receive array antennas N, each receive antenna coordinate x R,n N=0, 1,..n-1. Assuming that the transmit signals of the transmit antennas are orthogonal, then:
wherein s is m (t) represents the transmission signal of the mth antenna, s k (t) represents the kthTransmitting signal of antenna, delta mk Is a dirac function. At this time, the receiver separates the transmission signals using M matched filters for each reception antenna, so that the receiver obtains NM reception signals in total. Considering 1 far field point target, the target response obtained by the mth matched filter of the nth receive antenna can be expressed as:
Wherein u is t Is 1 unit vector pointing from radar transmitter to point target, alpha (t) And lambda is the carrier frequency wavelength of the transmitted signal and is the reflection coefficient of the point target.
It can be seen that the phase of the reflected signal is determined jointly by the transmitting antenna and the receiving antenna. Equivalently, the target response of equation (2) is exactly the same as that obtained for 1 array with NM antennas, and the equivalent array antenna position coordinates are:
{x T,m +x R,n |m=0,1,...,M-1;n=0,1,...,N-1} (3)
the Array with NM antennas is called Virtual Array (VA). When the MIMO radar is actually deployed, an array comprising NM virtual antennas which are not overlapped with each other can be constructed by reasonably setting the positions of a transmitting array and/or a receiving array and only by N+M physical antennas. Better angular resolution can be obtained because virtual arrays tend to be able to form larger array apertures.
Considering the implementation complexity and hardware cost, most 5G and 6G massive antenna arrays adopt a hybrid array architecture, i.e. one digital channel is individually connected to one physical antenna sub-array (i.e. one group of physical antenna array elements), and the sub-array senses one group of phase shifters to realize analog beamforming. The digital channel is often smaller than the actual number of physical antenna elements. If the traditional high-precision parameter estimation algorithm (such as MUSIC, ESPRIT and the like) is directly adopted, the high-precision angle sensing potential of the large-scale antenna array cannot be fully exerted. Document [4 ] ]An augmented beam domain angle estimation method is provided, which can solveThe above problems. The core idea is as follows. Consider a linear array of N antennas, where consecutive L antennas are a sub-array, connected to one digital channel via a phase shifter, for a total of M digital channels, i.e., n=ml. Let b m For the m-th sub-array, the antenna receives the signal vector r (n) ∈C N×1 Digital channel signal vector z (n) ∈C combined with shaping M×1 The relation of (2) is:
wherein B epsilon CN x M is an analog beamforming matrix. Obviously, the dimension of the received signal vector z (N) is changed from n×1 to m×1 compared to the full digital channel array, and if M is too small, on the one hand, the angular estimation resolution is reduced, and on the other hand, the number of signals that can be estimated is significantly limited. The augmented beam domain estimation method is based on the idea that by changing B, T groups of linearly independent z (n) are generated and spliced together, so that the degrees of freedom of the vector dimension and the correlation matrix of the received signals are further expanded, namely z (n) =B H (n) r (n), the received signal vector is [ z (n), z (n+1),. Z (n+t-1)]The dimension becomes mt×1.
3. New air interface (NR) beam management.
Currently, idle frequency bands of mobile communication networks are increasingly reduced, and there is a situation that the frequency band is gradually developed towards high frequency, such as millimeter wave (mmWave) pushed by 5GNR, and terahertz (THz) pushed by 6G, and these frequency bands have a large amount of available resources. However, higher frequencies mean greater transmission loss, and therefore beam management techniques are used in NR. In a mobile communication network, it is possible for both a base station and a User Equipment (UE) to form a beam with a narrow lobe width using beamforming. The purpose of beam management is to acquire and maintain a set of base station-terminal beam pairs available for Downlink (DL) and Uplink (UL) transmission/reception, thereby improving Link performance. Beam management includes the following aspects: beam scanning, beam measurement, beam reporting, beam indication, beam failure recovery.
In the downlink beam management process, beam scanning is divided into three phases of P1, P2 and P3, wherein:
stage P1: the base station and the terminal scan simultaneously, the beam of the base station is wider, and the reference signal is a synchronization signal block (Synchronization Signal and PBCH block, SSB). The protocol specifies the sending behavior of the base station, but the behavior of the terminal is not specified;
and P2: the terminal fixes the receiving beam, the base station scans the narrow beam, and the reference signal is a channel state information reference signal (Channel State Information Reference Signal, CSI-RS);
and P3: the base station fixes the transmitting beam (narrow beam), the terminal narrow beam scans, the terminal beam scans are self-behavior, the base station needs to cooperate with the fixed beam to send.
Of the three processes described above, P1 must be performed, and P2 and P3 are not required. On the basis of P1, if higher requirements are made of service, a P2 process can be executed; if the terminal capability is available and the base station considers that the service performance can be further improved, a P3 procedure can be performed. The P1 process usually depends on SSB only, the P3 process is not suitable for SSB because the terminal needs to be fixed to transmit beams, and the CSI-RS should be used, and the P2 process can be based on SSB or CSI-RS.
Beam scanning for upstream beam management is based on SRS. Similar to the downstream, it can be divided into stages U1, U2 and U3, wherein:
stage U1: the base station scans the transmitting beam of the terminal to determine the optimal transmitting beam of the UE, and simultaneously scans the receiving beam of the TRP to determine the optimal receiving beam of the base station; (this procedure is optional)
And U2: under the condition that the sending beam of the UE is fixed, the base station scans the receiving beam of the TRP and determines the optimal receiving beam;
and U3: on the premise of determining the optimal receiving beam, the base station selects the optimal UE transmitting beam by scanning the transmitting beam of the terminal;
uplink beam management may be accomplished by configuring dedicated sounding reference signal (Sounding Reference Signal, SRS) resources, or by determining the best uplink transmit beam (direction) from the best downlink transmit beam based on beam reciprocity.
If the receiving quality of the user control channel is lower than a certain threshold due to shielding, the terminal side initiates a beam failure recovery flow. The beam failure detection is mainly based on SSB or CSI-RS reference signals configured at the base station side. And the terminal detects that the number of failures is greater than or equal to the maximum number parameter of failures in the duration of the failure detection timer, triggers a beam failure recovery flow, TRP receives an uplink recovery request signal through receiving end beam scanning, reselects a new SSB corresponding beam according to the parameter configuration of beam recovery, initiates a random access process on a physical random access channel (Physical Random Access Channel, PRACH) resource for beam recovery, reestablishes a new beam pair with a base station, and recovers transmission.
4. And (5) sensing measurement.
In a mobile communication network, a base station (including some 1 or more transmission and reception points (Transmission Reception Point, TRP) on the base station, user Equipment (User Equipment, DMRS), UE (including 1 or more subarrays/panels (panels) on the UE), may be used as a sensing node participating in a sensing/passing integrated service.
Depending on whether the sensing node is the same device, two sensing modes can be divided: a sends out B and receives, A spontaneously self-receives. The A-sending B-receiving means that the sensing node A and the sensing node B are not the same equipment and are separated in physical position; a self-receiving means that the first signal transmission and reception are performed by the same device, and the sensing node a senses by receiving a signal echo transmitted by itself. This patent mainly discusses a transmit-receive sensing mode.
The node that sends and/or receives the first signal is referred to as a sensing node. The node for indicating, scheduling, controlling the Sensing node and calculating the Sensing result may be a certain node in the Sensing node, or may be a device in the core network, for example, a Sensing Function (SF), an access and mobility management Function (Access and Mobility Management Function, AMF), a Sensing application server in the core network, etc.
As 5G and future 6G will increasingly use high-band communications, NR introduces beam management for overcoming high-frequency attenuation, enhancing communication coverage, and guaranteeing communication quality. For a base station or UE with multiple antennas, one digital channel is typically connected to multiple physical antenna elements that produce directional beams using analog beamforming. When the sensing node senses less a priori information about the environment or the sensing traffic is sensing a larger area, a single beam of the above hardware architecture may not cover the sensing target/sensing area. If a wide beam is used to increase perceived coverage, the perceived angular resolution will decrease again due to the increased beam width. Furthermore, since fewer ports are used for beam management (SSB is single port, CSI-RS port number is 1 or 2 (cross polarization)), it is impossible or difficult to achieve high accuracy sensing based on MIMO radar principles.
To this end, the present application provides a sensing node with beam management of at least two ports (or multi-ports) where each port is mapped to a physical antenna/antenna sub-array of different array locations. Multiport aware beam management includes at least: sensing beam scanning, sensing beam measurement, sensing beam reporting/indication, sensing beam failure recovery. And obtaining the optimal sensing beam set of each port based on sensing beam measurement results of at least two ports, and further fully utilizing the array aperture to realize high-precision sensing.
The following describes in detail the perception processing method provided in the embodiments of the present application through some embodiments and application scenarios thereof with reference to the accompanying drawings.
Referring to fig. 2, an embodiment of the present application provides a sensing processing method, as shown in fig. 2, including:

Optionally, after determining the first measurement result, the first device may determine the first beam set, i.e. the beam set satisfying the sensing condition, according to the first measurement result. The at least one beam satisfying the sensing condition may be understood that the sensing measurement quantity corresponding to the at least one beam satisfies the sensing condition, that is, the measurement value of the sensing measurement quantity of the at least one beam is better, and may be used for a subsequent sensing service.

In this embodiment of the present application, because the state of the sensing target/area or the environment where the sensing service is located is changed, if some or all of the beams in the original first beam set do not belong to the best sensing beam any more, the sensing beam needs to be recovered, and the first beam set is determined again based on the first operation. Therefore, according to the embodiment of the application, the perception performance can be further improved.
It should be appreciated that since at least one of the first parameter configuration information and the second parameter configuration information is re-determined, it is necessary to re-perform the perceived beam scanning based on the re-determined first parameter configuration information and second parameter configuration information to re-determine the first beam set.
Optionally, the beam used for sensing beam detection is at least one beam of at least one port in the first set of beams. For example, the first sensing node or the sensing function network element may perform sensing beam detection based on a measurement value of a sensing measurement quantity of the sensing traffic.
Optionally, the decision condition for the perceived beam failure includes:
the measured value of at least one sensing measurement in the first wave beam set is lower than a third preset threshold in a second preset time period, or the times of being lower than the third preset threshold in the second preset time period is larger than the third preset times.
For a better understanding of the present application, the following detailed description is provided by way of some examples.
In some embodiments, the perception processing method provided by the application can realize high-precision recognition and positioning of the perception target. As shown in fig. 3, assuming that the terminal transmits the first signal using a fixed beam, the base station performs beam scanning and beam measurement to identify and locate a certain vehicle. Wherein the identification requires the base station to identify the target vehicle from a plurality of closely spaced vehicles and the positioning can be achieved by angulating and ranging the target. The sensing function network element initially determines the approximate range of beam scanning based on the historical prior information of the sensing target in the sensing request, such as the historical position information of the sensing target or the approximate area where the sensing target is located. The sensing function network element thus determines parameter configuration information of beam scanning and beam measurement, instructs the base station to perform beam scanning and measurement by using 6 ports (B1-B6) as shown in fig. 3 (in this example, it is assumed that each port maps 8 physical antenna elements, including different polarized antennas), and explicitly and/or implicitly indicates information such as the number of beams scanned by each port, precoding/beamforming vectors used by each beam scanning, and the like, and indicates a sensing measurement quantity to be measured in the beam measurement process of each port. The base station obtains the best set of perceived beams for the 6 ports of fig. 3 based on multi-port perceived beam scanning and measurement. Wherein the best perceived beam set for different ports may be different, for example port B1 and port B2 in fig. 3.
In some embodiments, trajectory tracking may be implemented based on the perception processing method provided herein. When the perceived target volume is small, high-precision trajectory perception of the target is necessary. Fig. 4 shows a schematic diagram of a base station and a terminal for tracking a target of an unmanned aerial vehicle. The base station is assumed to send a first signal, the terminal receives and feeds back a sensing result, or the terminal feeds back a measurement quantity, and the sensing result is calculated by the base station or the first device. In the beam management process, the base station and the terminal both perform beam scanning. If the beam measurement is performed at the terminal, the base station or needs to inform the terminal of its own parameter configuration information, including parameter configuration information of the first signal, precoding/beamforming matrixes of 6 ports (B1-B6) of the base station shown in fig. 4, mapping relation between precoding/beamforming vectors of 6 ports and IQ data of the first signal reception signal, the number of scanned beams, and physical antenna information mapped when the 6 ports perform beam scanning.
It should be noted that the first signal type for beam scanning and beam measurement, and their parameter configuration information, may be different from the first signal type and parameter configuration information used for the perceived service. In the beam scanning and beam measurement process, prior information of the general area of the unmanned aerial vehicle may not be obtained, and from the viewpoint of saving the overhead of sensing resources, beam scanning may be performed based on the SSB and/or CSI-RS signals of NR. And after the optimal sensing beam set is obtained, performing high-precision sensing by using the optimal sensing beam set based on other first signals. The other first signals may occupy more resources in the time-frequency domain. The beam scanning and beam measurement can also be different from the antenna ports used for the sensing service, for example, the beam scanning and beam measurement base station side only uses B2, B3, B5 and B6, and the sensing service process can use B1-B6 ports because the array type and array element layout of the physical antenna subarray mapped by the B1 and B4 ports are consistent with those of B2 and B5, wherein the B1 and B4 ports multiplex the precoding/beamforming matrixes of the B2 and B5 ports.
It should be noted that when the position of the unmanned aerial vehicle is moved greatly (for example, from position 1 to position 4 in the figure), a possible part of beams in the original best perceived beam set do not meet the condition as the best perceived beam, and beam recovery is required.
In some embodiments, the perception processing method provided based on the application can be used for perceived area environment reconstruction/object imaging. The embodiment of the application completes the sensing service based on the multiport sensing beam management process. The method is suitable for scenes with larger sensing area range and less possibility of changing the state of the sensing area in a short time, such as three-dimensional reconstruction of environment and imaging of objects. It should be noted that the number of base stations, terminals involved in the awareness may be more than one. When the sensing service is performed, the base station can send a first signal in beam scanning, and the terminal receives the first signal; the terminal may transmit the first signal during beam scanning, and the base station may receive the first signal. In the sensing request, a sensing result calculation node (for example, a sensing function network element) needs to acquire information such as a position of a base station, a terminal, an antenna panel orientation, and the like. Based on multi-port beam measurement, the sensing function network element can obtain information such as an exit angle (comprising an exit azimuth angle and an exit pitch angle), an arrival angle (comprising an arrival azimuth angle and an arrival pitch angle), a time delay, a complex amplitude and the like of the environment reflection paths of each base station or terminal side, and further obtain an environment reconstruction/object imaging result. It should be noted that, the computing node may also be a certain base station participating in sensing, and specific interaction information is not described herein again with reference to the above embodiment according to the difference of the computing nodes.
In some embodiments, the perception processing method provided based on the application can be used for realizing perception auxiliary communication. For example, if the perceived measurement quantity of the beam measurement includes a measurement quantity related to communication, such as the first signal received power, the best communication beam pair of the base station and the terminal can be obtained at the same time. Based on the multi-port known beam management, the primary reflector in the environment can be located. The information of the reflection paths of the sensing targets relative to the departure angles (including departure azimuth angles and departure pitch angles), arrival angles (including arrival azimuth angles and arrival pitch angles), time delay, complex amplitude and the like of the base station and the terminal in the same area and working in the sub 6GHz frequency band can be obtained by combining the position information of the base station and the terminal, and the information can be used for assisting the base station and the terminal in channel estimation and channel prediction. If the perception target is also a terminal for communication, the positioning result can be sent to the base station side for communication with the terminal to assist the terminal to carry out communication beam management, and the optimal communication beam alignment and updating are realized by using lower resource overhead compared with the traditional beam management.
