[0035] For the convenience of understanding, some contents related to the embodiments of the present application are described as follows:
[0036] I. NR beam management
[0037] The idle frequency bands of mobile communication networks are increasingly reduced, and the use of frequency bands is gradually developing towards high frequencies, such as millimeter wave (mmWave) promoted by 5G NR and terahertz (THz) promoted by 6G, which have a large number of available resources. However, higher frequencies mean greater transmission loss, so beam management technology is used in NR. In mobile communication networks, both the base station and the UE can use beamforming to form beams with narrow lobe widths. The purpose of beam management is to obtain and maintain a set of base station-UE beam pairs that can be used for downlink (DL) and uplink (UL) transmission / reception to improve the performance of the link. Beam management includes the following aspects: beam scanning, beam measurement, beam reporting, beam indication, and beam failure recovery.
[0038] In the downlink beam management process, beam scanning is divided into P1, P2 and P3 stages, wherein:
[0039] P1 stage: the base station (gNB) and the UE scan simultaneously, the beam of the gNB is wide, and the reference signal is a synchronization signal block (SSB).
[0040] P2 stage: the UE fixes the receiving beam, the base station scans the narrow beam, and the reference signal is a channel state information reference signal (CSI-RS);
[0041] P3 stage: the gNB fixes the transmitting beam (narrow beam), and the UE scans the narrow beam, which is a self-behavior of the UE, and the gNB needs to cooperate with the fixed beam transmission.
[0042] In the above three processes, P1 must be executed, and P2 and P3 are not necessarily executed. On the basis of P1, if there is a higher requirement for the service, the P2 process can be executed; if the terminal capability is available and the base station believes that the service performance can be further improved, the P3 process can be executed. P1 process usually only depends on SSB, P3 process cannot use SSB because it needs to fix the gNB transmitting beam, and should use CSI-RS, and P2 process can be based on SSB or CSI-RS.
[0043] The beam scanning of uplink beam management is based on sounding reference signals (SRS). Similar to downlink, it can be divided into U1, U2 and U3 stages, wherein:
[0044] U1 stage: gNB scans UE's transmit beam to determine UE's optimal transmit beam, while scanning TRP's receive beam to determine gNB's optimal receive beam (this process is optional);
[0045] U2 stage: gNB scans TRP's receive beam to determine the optimal receive beam, while UE's transmit beam is fixed;
[0046] U3 stage: gNB selects the optimal UE transmit beam by scanning UE's transmit beam, while the optimal receive beam is determined;
[0047] Uplink beam management can be completed by configuring dedicated SRS resources, or based on beam reciprocity, the best downlink transmit beam is used to determine the best uplink transmit beam.
[0048] In the idle state and initial access process, the downlink mainly relies on SSB, and the best SSB is selected by measuring the reference signal received power (RSRP) of the SSB beam scanning process. One SSB corresponds to one beam, and a group of SSBs used for beam scanning form a synchronization signal (SS) burst set. The maximum number of SSBs in a SS burst set is related to the frequency band, and the maximum number of SSBs in a millimeter wave frequency band is 64; the uplink mainly relies on PRACH, and PRACH has a mapping relationship with SSB. When initially accessing, the UE will first select the physical random access channel (PRACH) resource associated with the best SSB to send message 1 (MSG1). The base station determines the SSB beam selected by the UE according to the received UE uplink PRACH resource position, and sends downlink RAR and subsequent signaling on this SSB beam.
[0049] In the connected state, the downlink mainly relies on CSI-RS, and the base station configures one or more groups of CSI-RS for beam management to perform beam scanning. The UE obtains the layer 1 reference signal received power (L1-RSRP) result by measuring the CSI-RS, and reports the measurement results of different CSI-RS. The base station selects the CSI-RS beam with the strongest L1-RSRP to perform downlink channel transmission; the uplink mainly relies on SRS, and the multiple resource sets of SRS for beam management correspond to the UE's transmit panel (TX Panel), and each SRS resource in the resource set corresponds to a beam.
[0050] If the current user control channel reception quality is lower than a certain threshold due to occlusion, the UE initiates a beam failure recovery process. Beam failure detection is mainly based on base station configured SSB or CSI-RS reference signals. If the UE detects the number of failures within the failure detection timer duration is greater than or equal to the maximum number of failures parameter, it triggers the beam failure recovery process, and the TRP receives the uplink recovery request signal through the receiver beam scanning. The UE will reselect a new SSB corresponding beam according to the beam recovery parameter configuration, and initiate a random access process on the PRACH resource for beam recovery to reestablish a new beam pair with the base station and restore transmission.
[0051] II. Wireless sensing technology based on Fresnel region
[0052] With the rapid development of mobile communication networks and the Internet of Things, the types of wireless sensing methods are also increasing. The most common sensor-based sensing, such as smoke sensors, cameras / infrared sensors, and invasive sensors in the medical field, can achieve specific purpose sensing for specific scenarios. For user electronic product terminals, there are also some sensing applications, such as gesture recognition sensing for mobile phones or other electronic terminals, which can use infrared sensing or ultrasonic sensing. In recent years, wireless signal-based sensing research has also gradually increased. Compared with dedicated sensor sensing, wireless signal sensing has the advantages of simple equipment, low cost, non-invasive, and strong privacy. For example, wireless sensing based on WiFi signals can achieve home behavior monitoring, fall detection, intrusion detection, motion recognition, and daily activity route tracking. Currently, wireless sensing is mainly divided into two major representative directions in principle, one is wireless sensing based on pattern recognition, and the other is wireless sensing based on the Fresnel model. The basic principle of wireless sensing based on pattern recognition is to try to use machine learning / artificial intelligence technology for pattern recognition and classification, i.e., to establish a one-to-one mapping relationship between wireless sensing received signals and sensing target dynamics. However, due to the existence of multipath in wireless propagation, which in turn causes complex small-scale fading, this type of wireless sensing often has poor reproducibility in different environments and large sensing errors; the second type of wireless sensing based on the Fresnel region, the basic principle is to estimate and analyze the changes in wireless signal amplitude and phase caused by the sensing target cutting the Fresnel region, to achieve the dynamics of the target. This sensing method tries to reveal the relationship between the dynamics of the sensing target and the changes in wireless signal amplitude and phase from the wireless signal propagation mechanism, so it has strong interpretability and sensing accuracy.
[0053] When a transmitter and a receiver transmit wireless signals, a series of Fresnel zones of different sizes are formed. A Fresnel zone is an ellipsoidal zone with the transmitter and the receiver as the focal points. The propagation path of a reflection point on the ellipsoidal surface of a Fresnel zone differs from the direct path between the transmitter and the receiver by an integer multiple of a half wavelength of the signal. For example, the first ellipsoidal surface from the inside outward, the reflection path thereon differs from the direct path by one half wavelength, and this region is referred to as the first Fresnel zone. The region further outward, the reflection path differs from the direct path by two half wavelengths (i.e., one wavelength), and this region is referred to as the second Fresnel zone. The third...nth Fresnel zone can be obtained in the same way.
[0054] The environment between the transmitter TX and the receiver RX has multipath propagation, which can be divided into static paths and dynamic paths caused by the motion of the sensing target. When an object cuts through a Fresnel zone, the amplitude of the dynamic path can be approximately regarded as constant, but its phase changes, which eventually causes the amplitude of the overall channel vector composed of the channel vector of the static paths and the channel vector of the dynamic paths to change.
[0055] Based on the above principle, future electronic terminals, including mobile phone terminals and other electronic terminals such as electronic watches, various furniture controllers, etc., can all use the wireless signals in the environment for gesture recognition and sensing. The most common wireless signals in the environment include mobile network signals such as LTE and 5G downlink signals. The sensing terminal estimates the CSI according to the downlink channel to perform gesture recognition and motion sensing.
[0056] Since most wireless sensing scenarios based on the Fresnel zone model have wireless signals with wavelengths on the order of centimeters, and the communication signals often have a certain bandwidth, the wavelengths of different subcarrier frequencies within the bandwidth are slightly different. Therefore, the sensing terminal can often achieve action recognition on the scale of centimeters or even smaller. However, there is a serious defect in this sensing method at present, that is, the accuracy of gesture or action recognition is significantly affected by the position of the user in the Fresnel zone. As shown in Figure 2 When the user (i.e., the sensing target) is located between the base station and the sensing terminal, the user's gesture / action is likely to be in the first Fresnel zone, the diffraction and refraction of the signal are serious, the CSI signal pattern is not reproducible, and accurate gesture / action recognition cannot be performed in this area. When the user is near the extension line of the base station to the sensing terminal, the boundaries of different Fresnel zones are almost equally spaced, the CSI signal pattern is highly reproducible, the recognition accuracy is high, and therefore gesture / action recognition should be performed in this area as much as possible. For convenience of description, this area is referred to as the "first area" in this application; when the user is in the transition area between the above two areas, the recognition accuracy is not high, and therefore gesture / action recognition should be performed in this area as little as possible. For convenience of description, this area is referred to as the "second area" in this application. Figure 4As shown, the fluctuation mode of the CSI signal is easily affected by the orientation of the human body when making gestures / motions, and the CSI patterns of different orientations differ greatly, so try not to make gestures / motions in this area for gesture / motion recognition. For this reason, the scheme of the present application is proposed.
[0057] The perception measurement method provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings, some embodiments and application scenarios.
[0058] With reference to Figure 5 The perception measurement method provided by the embodiments of the present application includes:
[0059] Step 501, a first perception device determines a target beam meeting a target quality of service requirement, the target quality of service requirement being a perception quality of service requirement or a communication and perception quality of service requirement.
[0060] Step 502, the first perception device performs a perception service or a communication and perception service based on the target beam.
[0061] In the embodiments of the present application, the first perception device can be a terminal or a network side device, and the network side device can be a base station. The target quality of service requirement can be determined by a protocol or a network side device, and can also be provided by a perception service demander. The perception service demander refers to a device that proposes a perception requirement, for example, a terminal, a network side device or a third party application server, which is not limited further herein. The target beam meeting the target quality of service requirement can be understood as that when measurement is performed based on the target beam, a first measurement quantity associated with the perception quality of service can meet a preset perception quality of service (QoS) requirement, or a communication and perception QoS requirement of the first measurement quantity associated with the perception quality of service and a second measurement quantity associated with the communication QoS.
[0062] Optionally, the target beam includes at least one of a receiving beam and a transmitting beam, and in the case of the target beam including the receiving beam and the transmitting beam, the target beam can also be referred to as a target beam pair. The communication and perception service can also be referred to as a communication and perception integrated service, that is, simultaneously including a perception service and a communication service.
[0063] It should be understood that after the first perception device determines the target beam, in the process of performing the perception service, the target beam can be used for receiving the perception signal, or the target beam can be used for transmitting the perception signal, or the target beam can be used for transmitting and receiving the perception signal, so that the perception measurement can be realized based on the perception signal. In the process of performing the common perception service, the target beam can be used for receiving the common perception integrated signal, or the target beam can be used for transmitting the common perception integrated signal, or the target beam can be used for transmitting and receiving the common perception integrated signal, so that the common perception integrated measurement can be realized based on the common perception integrated signal.
[0064] Optionally, the above-mentioned perception service can be gesture, expression and body movement perception, recognition, etc. The measurement quantity in the perception service can be obtained at the UE, or can be obtained at the gNB; the conversion of the measurement quantity to the perception result can be performed at the UE, or can be performed at the gNB, or can be performed at the core network device. According to different situations, the execution of the perception service can use one of the following methods:
[0065] I. If the perception measurement quantity, including the first measurement quantity and the Doppler frequency measurement quantity, etc., is obtained at the UE, and the conversion of the perception measurement quantity to the perception result is performed at the UE, the downlink perception beam is used. At this time, the following process can be performed: 1. The UE can send a perception start indication message to the gNB (the best downlink beam index information of the gNB can be sent at the same time, and the best downlink beam is understood as the downlink beam in the target beam), and optionally, the UE starts a perception service timer; 2. After receiving the perception start indication message, the gNB sends the first signal to the UE using the best downlink beam, and optionally, the gNB starts a perception service counter; 3. The UE converts the perception measurement quantity to the perception result; optionally, the UE can send a measurement completion indication message to the gNB after completing the perception measurement quantity measurement. The function of the perception service timer is to set the maximum time of the perception service, which is started by the conversion of the perception measurement quantity to the perception result. The function of the perception service counter is to set the maximum number of times of transmitting the perception signal, which is started by the perception signal transmitter.
[0066] Two, if the acquisition of the perception measurement is performed at the gNB, the conversion of the perception measurement to the perception result is performed at the UE, and an uplink perception beam is used. At this time, the following procedures can be performed: 1. The UE sends a perception start indication message to the gNB. Optionally, the gNB can send a response message to the UE indicating that the perception service can be performed after preparation (the best uplink beam index information of the UE can be sent at the same time, and the best uplink beam can be understood as an uplink beam in the target beam). Optionally, the UE starts a perception service timer; 2. The UE sends a first signal to the gNB using the best uplink beam. Optionally, the UE starts a perception service counter; 3. The gNB sends the perception measurement obtained by uplink measurement to the UE. Optionally, the gNB can send a measurement completion indication message to the UE after completing the perception measurement; 4. The UE converts the perception measurement to the perception result.
[0067] Three, if the acquisition of the perception measurement is performed at the UE, the conversion of the perception measurement to the perception result is performed at the gNB, and a downlink perception beam is used. At this time, the following procedures can be performed: 1. The gNB sends a perception start indication message to the UE. Optionally, the UE can send a response message to the gNB indicating that the perception service can be performed after preparation (the best downlink beam index information of the gNB can be sent at the same time); optionally, the gNB starts a perception service timer; 2. The gNB sends a first signal to the UE using the best downlink beam. Optionally, the gNB starts a perception service counter; optionally, the UE can send a measurement completion indication message to the gNB after completing the perception measurement; 3. The UE reports the perception measurement obtained by downlink measurement to the gNB. Optionally, the UE can send a measurement completion indication message to the gNB after completing the perception measurement; 4. The gNB converts the perception measurement to the perception result.
[0068] Four, if the acquisition of the perception measurement and the conversion of the perception measurement to the perception result are performed at the gNB, and an uplink perception beam is used. At this time, the following procedures can be included: 1. The gNB sends a perception start indication message to the UE (the best uplink beam index information of the UE can be sent at the same time); optionally, the gNB starts a perception service timer; 2. The UE sends a first signal to the gNB using the best uplink beam; optionally, the UE starts a perception service counter; 3. The gNB converts the perception measurement obtained by uplink measurement to the perception result; optionally, the gNB can send a measurement completion indication message to the UE after completing the perception measurement.
[0069] V. If the conversion of the perception measurement quantity to the perception result is performed at the core network device, the node obtaining the perception measurement quantity is the UE or the gNB, and a corresponding downlink or uplink perception beam is used. At this time, the following processes can be included: 1. The core network device sends a perception start indication message to the gNB and / or the UE; optionally, the core network device starts a perception service timer; 2. One of the gNB or the UE uses the best downlink or uplink perception beam to send a first signal to the other party, and optionally, the first signal sender starts a perception service counter; 3. The first signal sender sends the perception measurement quantity obtained by measuring the first signal to the core network; optionally, the first signal receiver can send a measurement completion indication message to the first signal sender after completing the perception measurement quantity measurement; 4. The core network device completes the conversion of the perception measurement quantity to the perception result.
[0070] In the embodiments of the present application, by determining a target beam that meets the target service quality requirement, the perception service is performed based on the target beam, so that the target service quality requirement can be effectively guaranteed, and the perception performance is improved.
[0071] It should be noted that the perception service demander can send a perception demand to the core network device (such as a perception network function or a perception network element) to trigger the performance of the corresponding perception-related operation. According to whether the perception demand and the communication demand are initiated at the same time, there can be two cases. Case one: no communication service is performed in advance, and the perception service or the communication-perception service is directly initiated, for example, the perception service or the communication-perception service is performed for the first time, which is similar to the initialization access, no beam management is performed, and the perception service beam management needs to be performed to obtain a target beam that meets the target service quality requirement. Case two: the communication service is performed, and the perception service or the communication-perception service is initiated subsequently. Since the communication service has been performed, the beam management of the communication has been completed, and the first perception device has obtained the best communication beam, which is referred to as a first beam below. The first beam can include at least one of a transmission beam and a reception beam. In addition, the case where the communication service has been performed but the beam management process has not been performed can also be understood as belonging to case one, for example, a broadcast service.
[0072] For the above different cases, the way of determining the target beam that meets the perception demand is different. For example, in some embodiments, the first perception device determining the target beam that meets the perception demand includes:
[0073] The first perception device performs beam scanning using a first signal to obtain a target beam that meets the target service quality requirement, and the first signal includes at least one of a dedicated perception signal, a communication-perception integrated signal, and a reference signal.
[0074] Optionally, the above perception requirement can include at least one of the following: a target service quality requirement, a perception action type, a minimum (or maximum) duration of a single perception action, an average duration of a single perception action, a standard deviation of duration, a minimum number of repetitions of a perception action, and a maximum number of repetitions of a perception action. The target service quality requirement can include a perception service or common perception service type, a perception service or common perception service priority, a perception detection probability, a perception false detection probability, a perception identification accuracy requirement, a perception resolution requirement, a perception error requirement, a perception delay budget, a maximum perception range requirement, a continuous perception capability requirement, a perception update frequency requirement, and a communication QoS (when performing common perception integrated services), etc. The communication QoS can include a communication delay budget and a false alarm rate, etc. The perception action type can include gesture recognition, limb action recognition, and expression recognition, etc.
[0075] In the embodiments of the present application, both case one and case two can be applicable, i.e. whether to perform beam management for communication or not, directly perform beam management for perception service or common perception service to obtain a target beam satisfying the target service quality requirement. Only case one can also be applicable, i.e. only in the case of not performing beam management for communication, directly perform beam management for perception service or common perception service to obtain a target beam satisfying the target service quality requirement.
[0076] It should be understood that the above special perception signal and common perception integrated signal can be a newly designed special signal, and the above reference signal can be an LTE reference signal or an NR reference signal. If the NR reference signal is used, the downlink reference signal can be an SSB, a CSI-RS, a downlink positioning reference signal (DL-PRS), or a phase-tracking reference signal (PT-RS), etc. which can be configured in time domain. The uplink reference signal can be an SRS or an UL-SRS, etc. which can be configured in time domain.

When the first sensing device is a judgment node (i.e., capable of judging whether the first beam satisfies the target service quality requirement), the first sensing device can judge whether the first beam satisfies the target service quality requirement based on the first measurement result; if the first sensing device is not a judgment node (i.e., does not have the judgment capability), the first sensing device can report the first measurement result to the judgment node, and then determine whether the first beam satisfies the target service quality requirement according to the judgment result returned by the judgment node. The judgment node can be a base station or a core network device, which is not limited herein.
[0089] It should be understood that, assuming that the first sensing device is a base station and the second sensing device is a terminal in the embodiments of the present application, the above beam measurement can be understood as uplink beam measurement.
[0090] Optionally, the above-mentioned second signal and the above-mentioned first signal can both be understood as signals for sensing, the difference being that the two are used in different sensing measurement stages. The above-mentioned second signal and the first signal can be the same or different, and no further limitation is made herein.
[0091] Optionally, in some embodiments, the first sensing device performs beam measurement of the first beam, and determining whether the first beam meets the target quality of service requirement comprises:

[0098] Further, in some embodiments, the index of the first beam can be stored in case the first beam does not satisfy the target quality of service requirement, so that the communication can be resumed on the best communication beam after the execution of the sensing service or the common sensing service is finished, thereby improving the reliability of the communication and further reducing the signaling overhead. Whether to store the index of the first beam can be determined by the core network device or the base station, and in addition, the location where the index of the first beam is stored can also be the core network device or the base station.

[0106] The first measurement result is a sensing quality of service related measurement result, and the second measurement result is a communication quality of service related measurement result.
[0107] In the embodiments of the present application, the transmitting device of the first signal can be a second sensing device or other sensing device participating in sensing cooperation, which is understood as a device that does not perform sensing measurement, for example, can be a base station or a terminal, and is only used for transmitting the first signal. Specifically, the first sensing device can be understood as a receiving device of the first signal, and the process of beam sweeping between the transmitting device and the receiving device of the first signal can be set according to actual needs.
[0108] Optionally, assuming that the first sensing device is a terminal and the sending device is a base station, the first beam sweeping can be understood as a downlink beam sweeping. Assuming that the first sensing device is a base station and the sending device is a terminal, the first beam sweeping can be understood as an uplink beam sweeping. Assuming that the first sensing device is a terminal and the sending device is a terminal, the first beam sweeping can be understood as a beam sweeping of a sidelink. Of course, in other embodiments, the first sensing device and the sending device can both be base stations.
[0109] Optionally, in some embodiments, the first sensing device performs the beam sweeping using the first signal, and obtaining the target beam satisfying the target service quality requirement includes:
[0110] The first sensing device performs a second beam sweeping using the first signal;
[0111] The first sensing device determines the target beam satisfying the target service quality requirement according to second target information sent by a second sensing device;
[0112] The second target information is fourth measurement results measured by the second sensing device based on the second beam sweeping or beam information of a target beam satisfying the target service quality requirement determined by the second sensing device based on the fourth measurement results;
[0113] The first sensing device sends the first signal during the second beam sweeping.
[0114] Optionally, the fourth measurement results satisfy at least one of the following:
[0115] In a case where the first sensing device performs sensing services based on the target beam, the fourth measurement results include first measurement results, or the fourth measurement results include first measurement results and second measurement results;
[0116] In a case where the first sensing device performs sensing services based on the target beam, the fourth measurement results include first measurement results and second measurement results;
[0117] The first measurement quantity is a sensing service quality related measurement quantity, and the second measurement quantity is a communication service quality related measurement quantity.
[0118] In the embodiments of the present application, the first sensing device can be understood as the sending device of the first signal, the receiving device of the first signal can be the second sensing device, and the process of beam sweeping between the sending device and the receiving device of the first signal can be set according to actual needs.
[0119] Optionally, assuming the first sensing device is a terminal and the second sensing device is a base station, the above-mentioned second beam sweeping can be understood as uplink beam sweeping. Assuming the first sensing device is a base station and the second sensing device is a terminal, the above-mentioned second beam sweeping can be understood as downlink beam sweeping, and assuming the first sensing device is a terminal and the second sensing device is a terminal, the above-mentioned second beam sweeping can be understood as beam sweeping of a sidelink. Of course, in other embodiments, the first sensing device and the second sensing device can both be base stations.
[0120] It should be understood that the downlink beam sweeping can include three stages S1, S2 and S3:
[0121] S1 stage: the base station and the terminal sweep at the same time, the beam of the base station can be wider, and a newly designed sensing / interception integrated signal or SSB, etc. can be used. The simultaneous sweeping refers to that the base station can be fixed with different beams in turn, and the terminal sweeps the beams in turn when the base station is fixed with the beams; or the terminal can be fixed with different beams, and the base station sweeps the beams in turn when the terminal is fixed with the beams; until all possible beam pairs are traversed;
[0122] S2 stage: the terminal fixes the receiving beam, and the base station sweeps the narrow beam, which can use a newly designed sensing / interception integrated signal, or CSI-RS, or DL-PRS, etc.
[0123] S3 stage: the base station fixes the transmitting beam (narrow beam), and the terminal sweeps the narrow beam, and the terminal beam sweeping is a self-action, and the base station needs to cooperate with the fixed beam transmission.
[0124] Among them, the S1 stage is necessary, and the S2 and S3 are not necessary. On the basis of S1, if there is a higher requirement for the service, the S2 process can be performed; if the terminal narrow beam sweeping capability is possessed and the base station believes that the service performance can be further improved, the S3 process can be performed. It should be pointed out that the terminal performs beam sweeping, which can not only improve the sensing signal-to-noise ratio, but also suppress the interference (i.e. suppress the interference brought by other dynamic multi-paths in the environment).
[0125] The above-mentioned uplink beam sweeping includes three stages V1, V2 and V3, wherein:
[0126] V1 stage: the base station and the terminal sweep at the same time, and the optimal transmitting beam of the terminal and the optimal receiving beam of the base station are determined;
[0127] V2 stage: the base station sweeps the receiving beam of the TRP under the condition that the transmitting beam of the terminal is fixed, and the optimal receiving beam is determined;
[0128] V3 stage: the base station selects the optimal terminal transmitting beam by scanning the terminal transmitting beam on the premise of determining the optimal receiving beam.
[0129] It should be understood that when the beam consistency between the base station and the terminal is met, only uplink beam scanning or only downlink beam scanning can be performed. The beam consistency can be understood as that the transmitting beam and the receiving beam are completely reciprocal. In actual application, there can be inconsistency between the downlink beam and the uplink beam of the base station or the terminal, that is, the downlink optimal direction is not necessarily the uplink optimal direction (or the uplink optimal direction is not necessarily the optimal downlink direction).
[0130] Optionally, in the downlink beam scanning or the uplink beam scanning, the gNB can indicate the beam switching behavior of the UE through a DCI message, and inform the UE of the beam scanning behavior of the gNB side. The DCI message can include at least one of the following:
[0131] UE beam scanning start indication: that is, the gNB indicates that the UE can start beam scanning;
[0132] UE beam scanning sequence indication: that is, the gNB indicates the UE beam scanning sequence (which can be a series of beam indexes), and the UE beam scanning sequence corresponding to each gNB camping beam can be the same or different;
[0133] UE beam camping time indication: that is, the UE camping beam duration is indicated;
[0134] UE beam scanning stop indication: that is, the gNB indicates that the UE can end beam scanning;
[0135] gNB beam scanning start indication: that is, the gNB informs the UE that it starts beam scanning;
[0136] gNB beam scanning sequence indication: that is, the gNB tells the UE its beam scanning sequence (which can be a series of beam indexes), and the gNB beam scanning sequence corresponding to each UE camping beam can be the same or different;
[0137] gNB beam camping time indication: that is, the gNB informs the UE of its beam camping duration;
[0138] UE beam scanning stop indication: that is, the gNB informs the UE that it stops beam scanning.
[0139] Optionally, in the synchronization stage, the base station uses SSB, but after synchronization, both CSI-RS and SSB are used for beam scanning.
[0140] Optionally, in some embodiments, the first measurement quantity includes at least one of the following:
[0141] Channel state information (CSI) time series, CSI sample number, CSI time series smooth mean square error, CSI time series signal-to-interference-plus-noise ratio, CSI time series autocorrelation peak difference, CSI time series cycle standard deviation, CSI time series cycle variance, CSI time series amplitude standard deviation, CSI time series amplitude variance, and CSI time series reproducibility evaluation index.
[0142] Optionally, in some embodiments, the second measurement quantity can include at least one of: RSRP, received signal strength indication (RSSI), signal-to-noise ratio (SNR), and signal-to-noise and interference ratio (SINR).
[0143] It should be noted that, when the target beam is determined based on beam scanning, the target beam can be any one of the beams that meet the target service quality requirement, or can be the best perceived beam that meets the target service quality requirement. For example, in some embodiments, taking a base station and a terminal as perceived devices, the measurement and beam selection method can be at least one of the following methods:
[0144] Method 1: Based on downlink and / or uplink beam scanning, the scanning process simultaneously measures the first measurement quantity and the related measurement quantity (i.e., the second measurement quantity) that can indicate the received signal power, and after a round of scanning measurement (the scanning order is determined by the scanning party) is completed in a certain order, the base station best perceived beam is determined based on the measurement results.
[0145] Method 2: Based on downlink and / or uplink beam scanning, the scanning process simultaneously measures the first measurement quantity and the second measurement quantity, and scans and measures in a certain order (the scanning order is determined by the scanning party). Once the obtained measurement quantity meets the target service quality requirement, the beam pair is immediately selected, and the beam scanning is stopped.
[0146] Method 3: If the previous communication process has been established, it means that the beam scanning and measurement of the communication process have been performed. At this time, the current communication beam (i.e., the first beam) can be used as the starting scanning beam for the two nearest beam pairs, and the first measurement quantity on other beam pairs is measured in turn from near to far. Once the obtained first measurement quantity meets the target service quality requirement, the beam pair is immediately selected, and the beam scanning is stopped. In this way, the scanning time can be reduced, and the system resources and signaling overhead can be reduced.
[0147] Method 4: If the previous communication process has been established, it means that the beam scanning and measurement of the communication flow have been performed, at this time, the original several beam pairs of the communication beam pair which are better in the second measurement result can be used as candidate beam pairs, the first measurement is measured on these several beams, and finally the best beam pair is determined from the above candidate beams. The several beams which are better in the second measurement result can be obtained according to the previous communication (SSB or CSI-RS) beam scanning. Among them, the candidate beam pair does not include the first beam.
[0148] Optionally, if only downlink beam scanning is performed based on uplink and downlink beam consistency, the UE performs measurement of the first measurement, determines the best beam pair based on the measurement result, and reports the best downlink transmission beam to the gNB; if only uplink beam scanning is performed based on uplink and downlink beam consistency, the gNB performs measurement of the first measurement, determines the best beam pair based on the measurement result, and issues the best uplink transmission beam to the UE; if both downlink and uplink beam scanning are performed, the UE reports the best downlink transmission beam to the gNB, and the gNB issues the best uplink transmission beam to the UE.
[0149] Further, based on the beam scanning of the first signal, at least one of the following can be obtained:
[0150] The frequency domain position corresponding to the first signal meeting the target service quality requirement;
[0151] The time domain position corresponding to the first signal meeting the target service quality requirement;
[0152] The antenna or antenna port corresponding to the first signal meeting the target service quality requirement.
[0153] For example, the receiving end of the first signal can determine at least one of the following:
[0154] The index of the CSI (or received signal) frequency domain RE (or subcarrier) or resource block (Resource Block, RB) meeting the current service QoS (or perception quality requirement);
[0155] The time domain sampling slot index, or burst index, or equivalent time domain information (such as starting timestamp or starting time sampling point index) capable of indicating the CSI (or received signal) meeting the current service QoS (or perception quality requirement) of the CSI (or received signal) meeting the current service QoS (or perception quality requirement);
[0156] an antenna or antenna port index corresponding to a CSI (or received signal) satisfying a current service QoS (or perceived quality requirement), or equivalent information capable of associating the CSI (or received signal) satisfying the current service QoS (or perceived quality requirement) with the antenna / antenna port.
[0157] Optionally, before the first perception device performs beam sweeping on the first signal to obtain a target beam satisfying the target service quality requirement, the method further comprises:
[0158] The first perception device obtains perception parameter configuration information corresponding to the target service quality requirement, the perception parameter configuration information being used to configure transmission information of the first signal.
[0159] Optionally, the first perception device obtaining the perception parameter configuration information corresponding to the target service quality requirement comprises any one of the following:
[0160] The first perception device determines the perception parameter configuration information based on the target service quality requirement.
[0161] The first perception device receives the perception parameter configuration information sent by a target device based on the target service quality requirement, the target device being a core network device or a second perception device associated with the first perception device.
[0162] In the embodiments of the present application, the core network device can send the perception requirement to the perception device corresponding to the perception service or the general perception service, such as gNB and UE, and the gNB and UE can determine the perception parameter configuration according to the perception requirement. Optionally, the core network device can also directly send the perception parameter configuration information to the gNB or and / or UE. For example, the core network device can send the perception parameter configuration information to the base station, and the base station continues to send the perception parameter configuration information to the UE.
[0163] Optionally, in some embodiments, the perception parameter configuration information comprises at least one of the following: the first signal, frequency domain configuration parameters, time domain configuration parameters, spatial domain configuration parameters, and power configuration parameters.
[0164] The frequency domain configuration parameters can include a frequency domain span (pattern) of the first signal. If it is a uniform comb distribution, the starting index, interval, and other information of the corresponding resource element (RE) should be included; if it is a non-uniform distribution, all RE index information should be included.
[0165] The time domain configuration parameter can include a time domain pattern of the first signal. If it is a uniform comb distribution, the starting index, interval, and the like of the corresponding RE should be included; if it is a non-uniform distribution, all RE index information should be included. The time domain configuration parameter can also include the burst period of the first signal, the number of bursts, the burst duration of the first signal, and the time domain interval of the signal within the signal burst.
[0166] The spatial domain configuration parameter can include an antenna port index for sensing, an antenna index, an antenna spacing, and the number of antennas, and the like.
[0167] The power configuration parameter can include minimum transmit power, average transmit power, and maximum peak-to-average power ratio, and the like.
[0168] Optionally, in some embodiments, the sensing parameter configuration information at least meets at least one of the following:
[0169] The frequency domain configuration parameter needs to meet the delay (distance) sensing performance requirement of the sensing service or the common sensing service, and / or ensure that a sufficient number of CSI (or received signal) measurement samples meeting the target service quality requirement can be provided in the frequency domain;
[0170] The time domain configuration parameter needs to meet the Doppler sensing performance requirement of the sensing service or the common sensing service, and / or can ensure that a sufficient number of CSI (or received signal) measurement samples meeting the sensing target service quality requirement can be provided in the time domain, and / or ensure that a preset number of sensing measurement measurements can be completed on each scanning beam;
[0171] The spatial domain configuration parameter needs to meet the beam width requirement of the sensing service or the common sensing service.
[0172] The power configuration parameter needs to meet the SNR requirement of the sensing service or the common sensing service.
[0173] Optionally, in some embodiments, in the case that the first sensing device does not obtain a target beam meeting the target service quality requirement by performing beam scanning using the first signal, the method further includes:
[0174] The first sensing device outputs reminding information according to the beam scanning output, and the reminding information is used to prompt to change the angle of the sensing target relative to the first sensing device.
[0175] In the embodiments of the present application, the core network device or the gNB cooperates with the UE to instruct the UE to change its orientation / position. In some embodiments, the reminding information includes angle adjustment information of the sensing target relative to the first sensing device, and the angle adjustment information is determined based on the optimal communication beam of the first sensing device.
[0176] For example, in some embodiments, it is assumed that the UE does not have beamforming / beam scanning capability or has poor capability (omni-directional transceiver), and cannot find the best direction by itself beam scanning. At this time, the UE indicates that the user holds the UE and changes the orientation (or changes the position relative to the terminal), and then indicates to the gNB, based on the current gNB downlink / uplink beam pair, to measure the first measurement quantity. The UE indicates the user (i.e., the perception target) to select the final orientation according to the downlink / uplink beam measurement result.
[0177] In some embodiments, it is assumed that the UE has beamforming / beam scanning capability, and is based on the known best communication beam index (including uplink and / or downlink) of itself. The user is instructed to change the orientation (or change the position relative to the terminal) according to the beam index of itself. After changing the orientation, the UE can update the beam so that the updated beam direction is approximately the same as the original best communication beam direction, so as to improve the perception performance.
[0178] It should be understood that the adjustment of the user to the specified area can be achieved by the interaction between the UE and the user. The final result of changing the orientation / position is that the user (perception gesture / action performer) falls into the first area (the best perception area); if the target service quality requirement cannot be met by changing the orientation, it is considered that the current conditions do not meet the requirements of the perception service or the inter-sensing service.
[0179] Optionally, in some embodiments, before the first perception device performs beam scanning using the first signal to obtain a target beam satisfying the target service quality requirement, the method further comprises:
[0180] The first perception device sends perception capability information to a target device, and the perception capability information is used to determine a beam scanning manner;
[0181] The target device is a core network device or a second perception device associated with the first perception device, and the beam scanning manner includes at least one of a first beam scanning and a second beam scanning; in the process of the first beam scanning, the first signal is received by the first perception device; in the process of the second beam scanning, the first signal is transmitted by the first perception device.
[0182] Optionally, in some embodiments, the perception capability information includes beamforming capability information of the first perception device or beam scanning capability information of the first perception device.
[0183] Further, in some embodiments, the perception capability information further includes perception configuration parameter information, and the perception parameter configuration information is used to configure transmission information of the first signal.
[0184] In the embodiments of the present application, the core network device and / or the base station associated with the sensing terminal instructs the UE to report the sensing capability information. Optionally, the UE can report its own sensing capability information to the associated gNB and the core network device. Optionally, the gNB can also report its own sensing capability information to the core network device.
[0185] The core network device can determine whether to use downlink beam sweeping, uplink beam sweeping, or both uplink and downlink beam sweeping between the gNB and the UE according to the sensing capability information of the gNB and the UE.
[0186] The gNB determines whether to use downlink beam sweeping, uplink beam sweeping, or both uplink and downlink beam sweeping between the gNB and the UE according to the sensing capability information of the gNB and the UE.
[0187] It should be noted that when the wireless channel between the gNB and the UE changes, such as beam blocking occurs, it will cause beam failure. The sensing beam failure detection is determined based on the measurement result of the current target beam, such as when the first measurement quantity and / or the second measurement quantity continuously fall below a certain preset threshold within a certain preset time, it is determined as beam failure. In the case of judging beam failure, beam recovery can be performed based on at least one of the following methods:
[0188] Only partial beam failure including the current sensing beam, the other sensing beam satisfying the target service quality requirement can be selected based on the historical measurement result of the first measurement quantity;
[0189] Only partial beam failure including the current sensing beam, the sensing beam management can be re-performed to obtain the current optimal sensing beam;
[0190] All sensing beams fail, but the original best communication beam pair is available, switch back to the communication beam, and trigger the UE to output a reminder information to remind to change the angle of the sensing target relative to the first sensing device;
[0191] All sensing beams and the original best communication beam pair fail, re-initiate the communication beam management process, preferentially guarantee communication, and if there is still a sensing service or a common sensing service demand, trigger the UE to output a reminder information to remind to change the angle of the sensing target relative to the first sensing device.
[0192] Further, the conversion node of the measurement quantity to the sensing result sends the sensing result to the sensing demand side. The conversion node can be a terminal, a base station or a core network device. In addition, after the sensing service or the common sensing service ends, the communication service can be switched. Taking the sensing service as an example, the condition for switching back to the communication service can include one of the following:
[0193] The sensing demand direction core network device sends an end sensing service request, and the core network device informs the base station and / or the terminal to end the sensing service or switch back to the communication service;
[0194] The sensing service timer of the base station reaches a preset waiting time, or the sensing service counter of the base station reaches a maximum counting value; the base station informs the terminal and the core network device to end the sensing service or switch back to the communication service;
[0195] The sensing service timer of the terminal reaches a preset waiting time, or the sensing service counter of the terminal reaches a maximum counting value. The terminal informs the base station and the core network device to end the sensing service or switch back to the communication service.
[0196] Optionally, if the communication service is switched back, the base station and the terminal can switch back to the best communication beam pair according to the best communication beam pair index stored previously; optionally, if the original best communication beam pair cannot meet the communication QoS requirement due to channel change, the communication beam management process can be performed again.
[0197] In order to better understand the present application, the following is described through some specific examples.
[0198] Embodiment one: improve the gesture recognition performance of a mobile phone terminal.
[0199] For example, the gesture recognition performance of a mobile phone terminal can be improved. Figure 6As shown, assuming one UE in the network needs to conduct gesture recognition service (at this time the sensing terminal is a sensing-capable mobile phone). After the sensing service request is initiated, the network can determine the best beam pair between the gNB and the UE through the above method provided by the present application, so that the user falls into the above first area. Specifically, it can be achieved through downlink and uplink beam scanning and measurement, or through downlink (or uplink) beam scanning and measurement combined with beam consistency. Generally speaking, the base station has more antennas, so it can form narrower scanning beams. During the beam scanning process, the base station will stay on each beam for a certain period of time to complete the beam measurement. The best beam pair is determined based on the first measurement quantity combined with the second measurement quantity. Assuming downlink beam scanning and measurement, the gNB repeatedly transmits the first signal multiple times using the current beam within the beam stay time of the beam measurement process. During the beam measurement process, the first measurement quantity is caused by user action, but not necessarily by the gesture action the user wants to perform in the sensing service. For example, during the beam measurement process, the mobile phone application software instructs the user to adopt a certain fixed gesture, such as instructing the user to continuously draw "∞" in a space at an appropriate distance from the mobile phone, and the subsequent actual sensing service is to write Arabic numerals in the space, and the mobile phone senses the gesture and recognizes the written numerals; during the beam measurement process, the user can also not make a fixed gesture, and the mobile phone measures the user's breathing or heartbeat by receiving the first signal reflected by the user's body, and obtains the first measurement quantity result of the beam measurement, which can also reflect the sensing performance of the current beam pair, helping to determine the best beam pair.
[0200] Alternatively, the gNB scans and measures different direction beams in sequence. For beam 1 of the gNB, the direction is directly opposite the UE, which is the best uplink / downlink beam of the base station during pure communication service, but due to the relative position relationship of gNB-UE-user, the area where the user is located is not the best sensing area of the UE at this time; for beam 2, the user is between mirror gNB 2 and UE at this time, in the Fresnel zone of mirror gNB 2-UE, the sensing performance is the worst; for beam 3, the UE is in the best sensing area (i.e. the first area) corresponding to mirror gNB 1-UE, the sensing performance is the best at this time.
[0201] When conducting gesture recognition sensing service, the mobile phone can use pattern recognition or machine learning algorithms based on the downlink CSI time series or the time series of received signals, combined with the pre-acquired gesture data set in the application server database, to achieve user gesture recognition.
[0202] Embodiment two: determine the best beam pair by combining the first measurement quantity and the second measurement quantity.
[0203] As Figure 7As shown, it is assumed that one UE in the network needs to perform breathing + heartbeat awareness service (for example, the awareness terminal is a mobile phone with awareness function). After downlink / uplink beam scanning and beam measurement, there can be multiple candidate downlink transmission and / or uplink reception beams whose corresponding first measurement quantities all meet the awareness QoS requirements. For example, beam 4 and beam 5 in the figure can both make the user fall into the first area. At this time, the measurement quantity (the second measurement quantity) of the traditional communication beam management, such as the RSRP measurement result, can be comprehensively judged to determine the optimal downlink / uplink beam. Although the first measurement quantity measurement result of beam 4 in the figure can meet the awareness QoS requirements, because the corresponding signal propagation path is longer, the corresponding RSRP measurement result is relatively poor compared with the RSRP measurement result of beam 5, and therefore the optimal downlink / uplink beam at the gNB side is determined as beam 5.
