[0033] Example Wireless Communication System

It should be noted that Figure 1 Only one of many types and possible arrangements of wireless communication systems is shown; features of the present disclosure may be implemented in any of the various systems as desired.

[0035] like Figure 1As shown, the communication system 100 includes base stations 120A, 120B and terminal devices 110A, 110B to 110N. The base station and the terminal can be configured to communicate through uplink and downlink channels. The base stations 120A and 120B can be configured to communicate with a network 130 (e.g., a core network of a cellular service provider, a telecommunication network such as a public switched telephone network (PSTN), and / or the Internet). Therefore, the base stations 120A and 120B can facilitate communication between the terminal devices 110A to 110N and / or between the terminal devices 110A to 110N and the network 130.

[0036] exist Figure 1 In the present invention, the coverage area of ​​base stations 120A and 120B may be referred to as a cell. Base stations 120A and 120B may operate according to one or more radio access network technologies to provide continuous or nearly continuous communication signal coverage to terminal devices 110A to 110N over a wide geographical area.

[0037] like Figure 1 As shown, the communication system 100 includes a cloud 150 and a mobile edge computing node (MEC) 140.

[0038] In the present disclosure, a base station may be a 5G NR base station or a 5G LTE-A base station, such as a gNB and an ng-eNB. A gNB may provide an NR user plane and control plane protocol terminated with a terminal device; an ng-eNB is a node defined for compatibility with a 4G LTE communication system, which may be an upgrade of an evolved Node B (eNB) of an LTE radio access network, providing an Evolved Universal Terrestrial Radio Access (E-UTRA) user plane and control plane protocol terminated with a UE.

Some of the functions of the base station herein may also be implemented as an entity having a control function for communications in D2D, M2M, and V2X scenarios, or as an entity that plays a role in spectrum coordination in a cognitive radio communication scenario.

[0039] In the present disclosure, a terminal device may have the full breadth of its usual meaning, for example, a terminal device may be a mobile station (MS), a user equipment (UE), etc. The terminal device may be implemented as a mobile phone, a handheld device, a media player, a computer, a laptop, a tablet computer, an on-board unit (OBU) or a vehicle, a road side unit RSU (road side unit), a wearable device, an Internet of Things (IoT) device, or almost any type of wireless device.

For example, the terminal device may be configured to communicate using one or more of GSM, UMTS, CDMA2000, WiMAX, LTE, LTE-A, WLAN, NR, Bluetooth, etc.

[0040] Example beam scanning and pairing process

[0041] High-frequency millimeter wave communication is an important direction for mobile communications. Compared with low-frequency band transmission, millimeter wave has larger path loss and poorer reflection and diffraction capabilities. Therefore, a larger-scale antenna array is usually used to make the beamforming gain greater. Beamforming includes all-digital beamforming. In all-digital beamforming, each antenna in the antenna array has an independent digital link channel, which can control the amplitude and phase of the digital signal at the baseband. Due to the limited size of the millimeter wave antenna array, hybrid beamforming that combines analog beamforming with digital beamforming is more practical in terms of hardware complexity, cost overhead, and power consumption.

[0042] When link transmission is performed through analog beamforming technology, in order to obtain the best beam performance, the transmit / receive beam scanning method is usually used to search for matching transmit / receive beam pairs. The base station can only form a limited number of analog beams at the same time (the number of beams depends on the number of digital ports, and one digital port corresponds to one beam), and the beam width is narrow, usually only covering part of the cell. Therefore, it is necessary to broadcast the initial access synchronization signal, system broadcast message, etc. in the entire cell to cover the entire cell. That is, the formed beams cover different areas of the cell in turn to achieve complete coverage of the cell.

[0043] Figure 2 FIG. 1 shows a schematic diagram of beam scanning and pairing according to an embodiment of the present disclosure. Figure 2In the example, beam scanning and pairing are realized through three processes from P1 to P3. In the P1 process, the base station (for example, any one of 120A and 120B) sends a reference signal through multiple transmit beams to perform beam scanning. The reference signal can be, for example, a channel state information reference signal (CSI-RS) or a synchronization signal block (SSB). These multiple transmit beams are, for example, wide beams with weak directivity and large coverage. Accordingly, the terminal device (for example, any one of 110A to 110N) receives the reference signals sent by the base station through multiple transmit beams through one or more wide receive beams, respectively, and reports the beam scanning results to the base station. For example, the terminal device measures the received power of the reference signals sent through multiple transmit beams, respectively, and reports the transmit beam with the best receiving performance (for example, transmit beam A1 with the highest reference signal received power) to the base station. Accordingly, the base station determines transmit beam A1 as the beam that matches the terminal device; the terminal device uses the receive beam with the best receiving performance (for example, receive beam B1 with the highest reference signal received power) as the beam that matches the base station. The transmitting beam A1 on the base station side and the receiving beam B1 on the terminal device side are paired transmitting and receiving beams. In the P1 process, assuming that the base station side has M transmitting beams and the terminal device side has N receiving beams, it is necessary to send beams M×N times to complete the beam scanning.

[0044] During the P2 process, the base station forms a plurality of narrow beams near the transmit beam A1. For example, forming a plurality of narrow beams near the transmit beam A1 includes forming narrow beams within the coverage range and the adjacent range of the transmit beam A1. The base station sends a reference signal through a plurality of narrow transmit beams so as to perform beam subdivision between the plurality of narrow transmit beams. Accordingly, the terminal device receives the reference signal sent by the base station through the plurality of narrow transmit beams through the wide beam B1, and reports the beam scanning result to the base station. For example, the terminal device measures the received power of the reference signals sent through the plurality of narrow transmit beams respectively, and reports the transmit beam with the best receiving performance (e.g., the transmit beam A2 with the highest received power of the reference signal) to the base station. Accordingly, the base station determines the transmit beam A2 as the beam that matches the terminal device.

[0045] In the P3 process, the base station sends a reference signal through the narrow transmit beam A2 determined in the P2 process. Correspondingly, the terminal device forms multiple narrow beams near the receive beam A1, and receives the reference signal sent by the base station through the narrow transmit beam A2 through multiple narrow receive beams. For example, the terminal device measures the reference signal receiving power through multiple narrow receive beams respectively, and determines the narrow receive beam with the best receiving performance (for example, the narrow receive beam B2 with the highest reference signal receiving power) as the beam that matches the base station. The transmit beam A2 on the base station side and the receive beam B2 on the terminal device side are transceiver beams that are paired with each other.

[0046] In the embodiments of the present disclosure, as an addition or replacement to the traditional reference signal, an Integrated Sensing and Communication (ISAC) signal can be used in beam management. With the help of the sensing measurement capabilities of the base station and the terminal device, the matching transmit and receive beam pairs between the base station and the terminal device can be efficiently determined in a shorter time through fewer beam scans.

[0047] Example Electronic Devices

[0048] Figure 3A An example electronic device that can implement a base station (e.g., base station 120A, 120B) according to an embodiment of the present disclosure is shown. The electronic device 300A may include various units to implement various embodiments of beam management according to the present disclosure. Figure 3A In the example of FIG. 3 , the electronic device 300A includes a transceiver unit 302A and a sensing and processing unit 304A. Various operations described below in conjunction with base stations or beam management may be implemented by units 302A to 304A of the electronic device 300A or other possible units.

[0049] In one embodiment, the transceiver unit 302A may be configured to transmit a synaesthesia integration signal through a first group of multiple transmission beams, and in response to transmitting the synaesthesia integration signal, receive a first group of echo signals corresponding to a terminal device (e.g., any one of the terminal devices 110A to 110N). The sensing and processing unit 304A may be configured to estimate the location of the terminal device based on the first group of echo signals. The transceiver unit 302A may be further configured to send a first notification to the terminal device so that the terminal device can determine a first receiving beam (e.g., beam A1) that matches the base station.

[0050] In one embodiment, the transceiver unit 302A may be configured to establish a beam pair link with a terminal device (e.g., any one of the terminal devices 110A to 110N) using a first transmission beam (e.g., beam B2), and transmit a synaesthesia integration signal at a first transmission frequency through the first transmission beam. The transceiver unit 302A may be further configured to receive a first group of echo signals corresponding to the terminal device in response to transmitting the synaesthesia integration signal. The perception and processing unit 304A may be configured to obtain a mobile state of the terminal device based on the first group of echo signals. The perception and processing unit 304A may be further configured to determine a receiving beam to be tracked of the terminal device (e.g., other beams other than beam B2) based on the mobile state of the terminal device.

[0051] In an embodiment, the electronic device 300A may be implemented at a chip level, or may be implemented at a device level by including other external components (eg, a radio frequency chain, an antenna, etc.) The electronic device 300A may work as a communication device as a whole.

[0052] Figure 3B An example electronic device that can implement a terminal device (e.g., any one of the terminal devices 110A to 110N) according to an embodiment of the present disclosure is shown. The electronic device 300B may include various units to facilitate the implementation of various embodiments of beam management according to the present disclosure. Figure 3B In the example of FIG. 3 , the electronic device 300B includes a transceiver unit 302B and a processing unit 304B. Various operations described below in conjunction with the terminal device or beam management may be implemented by units 302B to 304B of the electronic device 300B or other possible units.

[0053] In one embodiment, the processing unit 304B may be configured to determine a first receiving beam that matches the base station from the first plurality of receiving beams based on a first notification received from the base station (e.g., the base station 120A or 120B). The transceiver unit 302B may be configured to receive the synaesthesia integration signal sent by the base station through the transmission beam through the first plurality of receiving beams. The processing unit 304B may be further configured to verify whether the first receiving beam is the best receiving beam that matches the base station based on a measurement of the synaesthesia integration signal.

[0054] In another embodiment, the transceiver unit 302B may be configured to establish a beam pair link with a base station (e.g., base station 120A or 120B) using a first receiving beam. The processing unit 304B may be configured to initiate or stop sensing of a synaesthesia signal sent by the base station based on a first notification received from the base station. The transceiver unit 302B may be further configured to feed back a sensing result to the base station.

[0055] In an embodiment, the electronic device 300B may be implemented at a chip level, or may be implemented at a device level by including other external components (eg, a radio frequency chain, an antenna, etc.) The electronic device 300B may work as a communication device as a whole.

[0056] It should be understood that the above-mentioned units are only logical modules divided according to the specific functions implemented by them, rather than being used to limit the specific implementation mode, for example, they can be implemented in software, hardware or a combination of software and hardware. In actual implementation, the above-mentioned units can be implemented as independent physical entities, or can also be implemented by a single entity (for example, a processor (CPU or DSP, etc.), an integrated circuit, etc.). Among them, the processing circuit can refer to various implementations of a digital circuit system, an analog circuit system or a mixed signal (a combination of analog and digital) circuit system that performs functions in a computing system. The processing circuit may include, for example, circuits such as an integrated circuit (IC), an application specific integrated circuit (ASIC), a part or circuit of a separate processor core, an entire processor core, a separate processor, a programmable hardware device such as a field programmable gate array (FPGA), and / or a system including multiple processors.

[0057] Perception-Assisted Beam Management

[0058] Figure 4 The example operation of the sensing-assisted beam management according to the embodiment of the present disclosure is shown. Figure 1 The example operation 400 is implemented by a base station 120A, 120B) or an electronic device 300A.

[0059] like Figure 4 As shown, the example operation 400 includes, for example, a base station 120A transmitting a synaesthesia integration signal via a plurality of transmit beams (402), and receiving a synaesthesia integration signal in response to receiving a synaesthesia integration signal from a terminal device (eg, Figure 1 The example operation 400 further includes the base station 120A estimating the position of the terminal device 110A based on the group of echo signals (406).

[0060] It should be understood that through operations 402 to 406, the base station 120A can realize the position perception of the terminal device 110A based on the synaesthesia integration signal. Depending on the transmission beam used by the base station 120A to send the synaesthesia integration signal, the position of the terminal device 110A relative to the base station 120A can be perceived with different accuracy. For example, when using a wider beam (e.g., similar to Figure 2 In the case of using a narrower beam (e.g., similar to beam A1 in FIG. 1 ), base station 120A can sense the approximate location of terminal device 110A. Figure 2In the case of beam A2 in the base station 120A, the base station 120A can perceive the finer position of the terminal device 110A. In one embodiment, the base station 120A can perceive at least one of the distance, speed or angle of the terminal device 110A relative to the base station 120A based on the time delay, Doppler frequency and phase difference information of the group of echo signals. The base station 120A can further estimate the position of the terminal device 110A relative to the base station 120A based on at least one of the distance, speed or angle of the terminal device 110A relative to the base station 120A.

[0061] For example, the location of the terminal device 110A can be estimated by obtaining a radio frequency map of the propagation environment. In high-frequency band scenarios, electromagnetic waves are mainly reflected. The base station 120A can decompose the multipath channel into multiple LOS channels of multiple anchor points. These anchor points are obtained by mirroring the base station 120A as the transmission point TP on the surface of the scatterer on each path. This transmission point can be called a virtual transmission point vTP (Virtual Transmission Point). Taking the co-station for transmission and reception as an example, the base station 120A can measure the time delay t between the transmission wave of the synesthesia integrated signal and the target echo. R , thereby determining the distance between the terminal device 110A as the target and the base station 120A: R = ct R / 2, where the speed of light is c. The target speed measurement mainly utilizes the Doppler effect generated by the movement of the terminal device 110A. The base station 120A can measure the Doppler frequency of the echo signal to estimate the speed of the terminal device 110A, where the Doppler frequency f d =2v / λ, where v is the target speed and λ is the signal wavelength. The target angle measurement is mainly performed by overlapping multiple antenna beams or multiple phase centers, and the angle of the terminal device 110A is measured by the intensity difference between the echoes output by different beams or the phase difference between the multiple phase centers and the output target echoes.

[0062] like Figure 4 As shown, the example operation 400 also includes the base station 120A performing beam management (408) between the base station 120A and the terminal device 110A based on the estimated position of the terminal device 110A. For example, the estimated position of the terminal device 110A can be used to assist in beam scanning or beam tracking processes. In one embodiment, the base station 120A can determine the transmit beam and / or receive beam paired between the base station 120A and the terminal device 110A based on the estimated position of the terminal device 110A, as described in detail below. In another embodiment, the base station 120A can determine the receive beam to be tracked of the terminal device 110A based on the estimated position of the terminal device 110A, as described in detail below.

[0063] Figure 55 shows an example process for beam scanning and pairing according to an embodiment of the present disclosure. The example process 500 may be performed between the base station 120 (or the electronic device 300A) and the terminal device 110 (or the electronic device 300B). For example, the base station 120 may be Figure 1 The terminal device 110 may be any of the base stations 120A and 120B in Figure 1 Any one of the terminal devices 110A to 110N in the embodiment. In an embodiment, the example process 500 can be used to implement the P1 process of beam scanning.

[0064] like Figure 5 As shown, at 502, the base station 120 transmits a synaesthesia integration signal via a first plurality of transmit beams. The first plurality of transmit beams are relatively wide beams, such as Figure 2 In one embodiment, transmitting the synaesthesia integration signal via the first plurality of transmit beams includes transmitting the synaesthesia integration signal only in a single cycle of the first plurality of transmit beams (rather than Figure 2 Send M×N times as in ).

[0065] At 504, in response to sending the synaesthesia integration signal, the base station 120 receives a first group of echo signals corresponding to the terminal device 110. In one embodiment, upon receiving the synaesthesia integration signal, the terminal device 110 may send a confirmation message to the base station 120. For example, the confirmation message may indicate that the synaesthesia integration signal has been received. Upon receiving the confirmation message, the base station 120 identifies the echo signals received within a specific time window before and after receiving the confirmation message as a group of echo signals corresponding to the terminal device 110. For example, depending on actual needs, the size of the time window may be set to 10ms, 20ms, 50ms, 100ms, or 200ms, etc.

[0066] At 506, after receiving the first group of echo signals corresponding to the terminal device 110, the base station 120 estimates the position of the terminal device 110 with a first accuracy based on the sensing. Since the first group of transmission beams is a wider beam, the first accuracy may be relatively low, and the base station 120 thus obtains the approximate position of the terminal device 110. The specific operation of estimating the position of the terminal device 110 can be understood with reference to operation 408. In one embodiment, based on the estimated position of the terminal device 110, the base station 120 can determine a first transmission beam (e.g., a first transmission beam) that matches the terminal device 110 from the first group of multiple transmission beams. Figure 2 The base station 120 may also determine, based on the estimated position of the terminal device 110, a first receiving beam (eg, Figure 2 beam B1 in the image).

[0067] At 508, the base station 120 sends a first notification to the terminal device 110 so that the terminal device 110 can determine the receiving beam that matches the base station 120. In one embodiment, when the base station 120 has determined the first receiving beam that matches the base station 120 on the terminal device 110 side, the base station 120 may indicate the first receiving beam in the first notification. In another embodiment, the base station 120 may indicate the position of the terminal device 110 relative to the base station 120 in the first notification so that the terminal device 110 can determine the first receiving beam that matches the base station 120.

[0068] It should be understood that in the example process 500, the synaesthesia integration signal can be sent only in a single cycle of at least the first group of multiple transmission beams, so that the transmission beam and the receiving beam paired between the base station 120 and the terminal device 110 can be obtained based on the perception of the position of the terminal device 110. Compared with the traditional P1 process that requires the transmission and reception beam scanning, for example, M×N times, the example process 500 is more efficient and can achieve a beam scanning result equivalent to the P1 process in a shorter time with lower processing overhead.

[0069] Figure 6 Another example process for beam scanning and pairing according to an embodiment of the present disclosure is shown. The example process 600 may be performed between the base station 120 (or the electronic device 300A) and the terminal device 110 (or the electronic device 300B). For example, the base station 120 may be Figure 1 The terminal device 110 may be any of the base stations 120A and 120B in Figure 1 Any one of the terminal devices 110A to 110N in. In an embodiment, the example process 600 can be used to implement the P2 and P3 processes of beam scanning.

[0070] like Figure 6 As shown, at 602, the base station 120 transmits the synaesthesia integration signal via a second plurality of transmit beams. The second plurality of transmit beams are narrower beams, such as Figure 2 In one embodiment, the second plurality of transmit beams are formed by the base station 120 near the first transmit beam determined in the example process 500. For example, the second plurality of transmit beams may be formed within the coverage of the first transmit beam or also within the vicinity of the first transmit beam. In one embodiment, sending the synaesthesia integration signal through the second plurality of transmit beams includes sending the synaesthesia integration signal only in a single cycle of the second plurality of transmit beams.

[0071] At 604, in response to sending the synaesthesia integration signal, the base station 120 receives a second group of echo signals corresponding to the terminal device 110. In one embodiment, upon receiving the synaesthesia integration signal, the terminal device 110 sends a confirmation message to the base station 120. For example, the confirmation message may indicate that the synaesthesia integration signal has been received. Upon receiving the confirmation message, the base station 120 identifies the echo signals received within a specific time window before and after receiving the confirmation message as a group of echo signals corresponding to the terminal device 110. For example, depending on actual needs, the size of the time window may be 10ms, 20ms, 50ms, 100ms, or 200ms, etc.

[0072] At 606, after receiving the second group of echo signals corresponding to the terminal device 110, the base station 120 estimates the position of the terminal device 110 with a second accuracy based on the perception. Since the second group of transmit beams is a narrower beam, the second accuracy can be relatively high, and the base station 120 therefore obtains a more precise position of the terminal device 110. The specific operation of estimating the more precise position of the terminal device 110 can be understood with reference to operation 408. In an embodiment, the example process 600 can be performed after estimating the approximate position of the terminal device 110 in the example process 500, so as to re-estimate the more precise position of the terminal device 110. In one embodiment, based on the estimated position of the terminal device 110, the base station 120 can determine a second transmit beam (e.g., a second transmit beam) that matches the terminal device 110 from the second group of multiple transmit beams. Figure 2 The base station 120 may also determine a second receiving beam (e.g., beam A2) on the side of the terminal device 110 that matches the base station 120 based on the estimated position of the terminal device 110. Figure 2 beam B2 in the image).

[0073] In one embodiment, the terminal device 110 can determine the first receiving beam (eg, Figure 2The beam B1 in 604 receives and measures the synaesthesia integration signal sent at 602. For example, the synaesthesia integration signal can be designed to carry a channel state information reference signal CSI-RS or a similar reference signal. The terminal device 110 can measure the reference signal and feedback the corresponding measurement report to the base station 120 for the second group of multiple transmit beams. It should be noted that compared with the base station 120 sensing based on the echo signal received at 604, the measurement of the reference signal carried by the synaesthesia integration signal by the terminal device 110 may take longer. Therefore, the narrower transmit beam matching between the base station 120 side and the terminal device 110 can be determined based on the echo signal first. Afterwards, the base station 120 can verify whether the determined transmit beam is the best beam matching the terminal device 110 based on the measurement report fed back by the terminal device 110, and adjust the matching beam when necessary. This operation is efficient, and can quickly determine the matching transmit beam, and can ensure that the determined transmit beam is the best matching beam.

[0074] At 608, the base station 120 sends a second notification to the terminal device 110, so that the terminal device 110 can determine the receiving beam that matches the base station 120 (eg, Figure 2 In one embodiment, when the base station 120 has determined the second receiving beam on the terminal device 110 side that matches the base station 120, the base station 120 may indicate the second receiving beam in the second notification. In another embodiment, the base station 120 may indicate the position of the terminal device 110 relative to the base station 120 in the second notification, so that the terminal device 110 can determine the second receiving beam that matches the base station 120. It should be noted that since the more precise position of the terminal device 110 is estimated at 606, a narrower receiving beam on the terminal device 110 side that matches the base station 120 can be determined accordingly.

[0075] In one embodiment, after determining the receiving beam that matches the base station 120, the terminal device 110 can additionally measure the reference signal from the base station 120 through its multiple receiving beams, thereby verifying whether the determined matching receiving beam is the best, and can adjust it when necessary. This operation is efficient, and can not only quickly determine the matching receiving beam, but also ensure that the determined receiving beam is the best matching beam.

[0076] It should be understood that in the example process 600, the synaesthesia integration signal can be sent at least only in a single cycle of the second group of multiple transmit beams, so that the narrower transmit beam and receive beam paired between the base station 120 and the terminal device 110 can be obtained based on the perception of the finer position of the terminal device 110. Compared with the traditional P2 and P3 processes, the example process 600 is more efficient and can achieve beam scanning results equivalent to the P2 and P3 processes in a shorter time with lower processing overhead.

[0077] Figure 7 FIG. 2 shows an example of the transmission configuration information TCI state according to an embodiment of the present disclosure. Figure 7 As shown, the TCI state is identified by a TCI state ID and may include, for example, one or two quasi-co-location (QCL) types. For example, the structure of the TCI state may be {source reference signal 1|QCL type 1, source reference signal 2|QCL type 2} or {source reference signal 1|QCL type 1}. The source reference signal may include a CSI-RS or an SSB. In an embodiment of the present disclosure, at least one of QCL type 1 and type 2 is type D. QCL type D indicates that the target reference signal has the same spatial reception parameters as the source reference signal (referSignal) in the TCI state. In one embodiment, the first notification or the second notification in example processes 500 and 600 may include a TCI state.

[0078] In one embodiment, the base station 120 may determine the receiving beam of the terminal device 110 based on the estimated position of the terminal device 110, and the reference signal corresponding to the receiving beam is the target reference signal. Then, the base station 120 may determine the source reference signal having a QCL type D relationship with the target reference signal based on the QCL relationship of each reference signal obtained by a previous beam scanning operation, for example, during random access. Accordingly, after receiving the TCI state, the terminal device 110 may determine the source reference signal and the corresponding spatial reception parameters, and use the spatial reception parameters to configure the antenna array for receiving operation. For example, the terminal device 110 may obtain the spatial reception parameters of the source reference signal based on a previous beam scanning operation.

[0079] In one embodiment, the TCI state may be configured through RRC signaling. The TCI state may also be configured through RRC signaling and activated through MAC-CE. The TCI state may also be configured through RRC signaling, activated through MAC-CE, and indicated through DCI.

[0080] Figure 8 FIG. 8 is a flowchart of an exemplary process for beam tracking according to an embodiment of the present disclosure. The exemplary process 800 may be performed between the base station 120 (or the electronic device 300A) and the terminal device 110 (or the electronic device 300B). For example, the base station 120 may be Figure 1 The terminal device 110 may be any of the base stations 120A and 120B in Figure 1 Any one of the terminal devices 110A to 110N.

[0081] like Figure 8 As shown, at 802, the base station 120 and the terminal device 110 establish a beam pair link through the paired transmit and receive beams determined in the beam scanning. In one embodiment, the paired transmit and receive beams are such as Figure 2 It should be understood that when a beam pair link has been established, the base station 120 and the terminal device 110 need to track the performance of other beams so as to quickly establish a new beam pair link through other beams when the performance of the currently paired narrow beam decreases.

[0082] At 804, the base station 120 transmits the synaesthesia integration signal at a first transmission frequency through the established beam pair link. The first transmission frequency can be a relatively low frequency, so that the base station 120 transmits the synaesthesia integration signal at a period of, for example, 50ms, 100ms, 200ms, or 500ms. At 806, in response to transmitting the synaesthesia integration signal, the base station 120 receives a group of echo signals corresponding to the terminal device 110.

[0083] At 808, based on the group of echo signals, the base station 120 determines the mobile state of the terminal device 110 and the receiving beam to be tracked of the terminal device 110. In one embodiment, the base station 120A may sense at least one of the distance, speed or angle of the terminal device 110A relative to the base station 120A based on the time delay, Doppler frequency and phase difference information of the group of echo signals. The base station 120A may further estimate the mobile state of the terminal device 110A relative to the base station 120A based on at least one of the distance, speed or angle of the terminal device 110A relative to the base station 120A. In one embodiment, the receiving beam to be tracked of the terminal device 110 may be determined based on the mobile state of the terminal device 110.

[0084] Based on the perception of the mobile state of the terminal device 110, the mobile state change rate of the terminal device 110 can be known. In one embodiment, the mobile state change rate may involve the speed and / or acceleration of the terminal device 110. It should be noted that a higher speed means that the position of the terminal device 110 changes faster, and a higher acceleration means that the position change of the terminal device 110 is less stable. Either case may cause the current beam link between the base station 120 and the terminal device 110 to fail. Therefore, it is necessary to track the beam performance between the base station 120 and the terminal device 110 more frequently. Accordingly, when the mobile state change rate is lower than the threshold, the position change of the terminal device 110 is slower. Therefore, operations 802 to 808 can be repeatedly performed to send a synaesthesia integration signal at a lower first frequency and perform beam management. When the mobile state change rate is higher than the threshold, the position change of the terminal device 110 is faster. Therefore, it is necessary to update the mobile state and position information of the terminal device 110 more frequently and more accurately so as to keep tracking the receiving beam of the terminal device 110.

[0085] At 810, in response to determining that the rate of change of the mobile state of the terminal device 110 is higher than the threshold, the base station 120 sends the synaesthesia integration signal at a second transmission frequency. The second transmission frequency is higher than the first transmission frequency, so that the base station 120 sends the synaesthesia integration signal at a period of 20ms, 40ms, 60ms or 80ms, etc. At 812, in response to sending the synaesthesia integration signal, the base station 120 receives a group of echo signals corresponding to the terminal device 110. Due to the higher transmission frequency of the synaesthesia integration signal, the base station 120 can collect the group of echo signals in a shorter time. At 814, based on the group of echo signals, the base station 120 can quickly determine the mobile state of the terminal device 110 and the receiving beam to be tracked of the terminal device 110. Thereafter, based on the relationship between the rate of change of the mobile state of the terminal device 110 and the threshold, it can be selected to send the synaesthesia integration signal at the first frequency or the second frequency.

[0086] Fig. 9 Another example process for beam tracking according to an embodiment of the present disclosure is shown. The example process 900 may be performed between the base station 120 (or the electronic device 300A) and the terminal device 110 (or the electronic device 300B). For example, the base station 120 may be Figure 1 The terminal device 110 may be any of the base stations 120A and 120B in Figure 1 Compared with the example process 800, when the mobile state change rate of the terminal device 110 is higher than the threshold, the example process 900 can more accurately update the mobile state and location information of the terminal device 110 based on the measurement report of the terminal device 110.

[0087] You can refer to Figure 8 Operations 902 to 908 can be understood by referring to operations 802 to 808 in FIG. Fig. 9 As shown, at 910, in response to determining that the rate of change of the mobile state of the terminal device 110 is higher than the threshold, the base station 120 sends a synaesthesia integration signal and a notification message to the terminal device 110. Upon receiving the notification message, at 911, the terminal device 110 may initiate a perception measurement of the synaesthesia integration signal sent by the base station 120, and then feed back the perception measurement result to the base station 120.

[0088] In one embodiment, the terminal device 110 performs perceptual measurement on the synaesthesia integrated signal, including performing multipath measurement on the perceptual signal. Multipath parameter estimation mainly estimates the M main multipath components of each transmit beam received by the terminal device, including the time delay τ j , Doppler f j , channel path coefficient p j and angle of arrival, including elevation and azimuth The parameters are combined into a vector denoted as V j Assume that the transmitted signal on the mth beam is s m(t) , the received signal can be expressed as:

[0089]

[0090] Among them, X j,(m) (t:V (j) ) is the transmitted signal of the jth path. The space generalized alternating algorithm is used to perform iterative optimization estimation by alternately optimizing the delay, Doppler, signal coefficient and arrival angle component on the estimated parameters of each path. For example, the space alternating generalized expectation (SAGE) maximization can be used to reduce the computational complexity. By using alternating optimization on the estimated parameters of each path, the convergence speed of the maximization step is improved.

[0091] At 912, in response to sending the synaesthesia integration signal, the base station 120 receives a group of echo signals corresponding to the terminal device 110. At 913, the base station 120 receives a measurement report from the terminal device 110. At 914, on the one hand, based on the group of echo signals, the base station 120 can determine the mobile state of the terminal device 110 and the receiving beam to be tracked of the terminal device 110. On the other hand, the base station can also determine the mobile state of the terminal device 110 and the receiving beam to be tracked of the terminal device 110 based on the measurement report. In one embodiment, the base station 120 can mutually verify the results determined based on the group of echo signals and the perception measurement report, thereby improving the accuracy of the beam tracking operation.

[0092] When it is determined in 914 that the rate of change of the mobile state of the terminal device 120 is still higher than the threshold, the terminal device 120 may continue to feed back the perception measurement result to the base station 110. Otherwise, at 916, in response to determining that the rate of change of the mobile state of the terminal device 110 is lower than the threshold, the base station 120 sends a synaesthesia integration signal and a notification message to the terminal device 110, so that the terminal device 110 stops the perception measurement of the synaesthesia integration signal sent by the base station 120.

[0093] It should be noted that in the example process 900, the frequency at which the base station 120 sends the synaesthesia integration signal at operation 910 can also be increased, so that the group echo signal can be collected in a shorter time. In such an embodiment, the movement state and location information of the terminal device 110 can be updated more accurately and quickly, so that beam tracking can be performed more accurately and quickly.

[0094] Fig.10 1000 is another example process for beam tracking according to an embodiment of the present disclosure. The example process 1000 may be performed between the base station 120 (or the electronic device 300A), the terminal device 110 (or the electronic device 300B), the access and mobility function (AMF) entity, and the sensing function (SF) entity. For example, the base station 120 may be Figure 1 The terminal device 110 may be any of the base stations 120A and 120B in Figure 1 Any one of the terminal devices 110A to 110N.

[0095] In example processes 800 and 900, the base station 120 processes the sensing data to perform beam tracking. The sensing data may include the sensing data obtained by the base station 120 itself and the sensing data sensed and fed back by the terminal device 110. In example process 1000, the network function entity may assist the base station 120 in processing the sensing data.

[0096] like Fig.10As shown, at 1002, the base station 120 obtains the perception data based on its own perception or based on the feedback of the terminal device 110. At 1004, the base station 110 provides the perception data to the SF entity through the AMF entity. At 1006, the SF entity processes the perception data. In one embodiment, the SF entity can perceive at least one of the distance, speed or angle of the terminal device 110A relative to the base station 120A based on the delay, Doppler frequency and phase difference information of the group of echo signals. The SF entity can further estimate the position of the terminal device 110A relative to the base station 120A based on at least one of the distance, speed or angle of the terminal device 110A relative to the base station 120A. At 1008, the SF entity provides the perception data processing result to the base station 120 through the AMF entity. It should be understood that the SF function is only an example of a perception network element. In different implementations, the SF function can be implemented as a separate entity or implemented together with other entities.

[0097] Fig.11 FIG. 1 shows a first exemplary method for communication according to an embodiment of the present disclosure. The method may be performed by a terminal device (eg, any one of 110A to 110N) or an electronic device 300B. Fig.11 As shown, the method 1100 may include determining a first receiving beam (e.g., beam B2) that matches the base station from a plurality of receiving beams based on a notification received from the base station (e.g., the notification at 608) (box 1102). The method may include receiving, through the plurality of receiving beams, a synaesthesia integration signal sent by the base station through a transmitting beam (box 1104). The method may also include verifying, based on a measurement of the synaesthesia integration signal, whether the first receiving beam (e.g., beam B2) is the best receiving beam that matches the base station (box 1106). Further details of the method may be understood with reference to the description of the terminal device or electronic device 300B above.

[0098] Fig.12 FIG. 2 shows a second exemplary method for communication according to an embodiment of the present disclosure. The method may be performed by a terminal device (eg, any one of 110A to 110N) or an electronic device 300B. Fig.12 As shown, the method 1200 may include establishing a beam pair link with a base station using a first receive beam (e.g., beam B2) (block 1202). The method may include initiating or stopping a perceptual measurement of a synaesthesia signal sent by the base station based on a notification received from the base station (e.g., notifications at 910 and 916) (block 1204). The method may also include feeding back the measurement result to the base station (block 1206). Further details of the method may be understood with reference to the description of the terminal device or electronic device 300B above.

[0099] The above describes each exemplary electronic device and method according to the embodiments of the present disclosure. It should be understood that the operations or functions of these electronic devices can be combined with each other to achieve more or less operations or functions than described. The operating steps of each method can also be combined with each other in any appropriate order to similarly achieve more or less operations than described.

[0101] In addition, it should be understood that the above series of processes and devices can also be implemented by software and / or firmware. In the case of being implemented by software and / or firmware, from a storage medium or a network to a computer with a dedicated hardware structure, such as Fig.13 The general-purpose computer 1300 shown installs programs constituting the software, and when the various programs are installed, the computer can execute various functions and the like. Fig.13 An example block diagram of a computer that can be implemented as a terminal device or a base station according to an embodiment of the present disclosure is shown.

[0102] exist Fig.13 In the embodiment, a central processing unit (CPU) 1301 executes various processes according to a program stored in a read-only memory (ROM) 1302 or a program loaded from a storage section 1308 to a random access memory (RAM) 1303. In the RAM 1303, data required when the CPU 1301 executes various processes and the like is also stored as needed.

[0103] The CPU 1301, the ROM 1302, and the RAM 1303 are connected to each other via a bus 1304. To the bus 1304, an input / output interface 1305 is also connected.

[0104] The following components are connected to the input / output interface 1305: an input section 1306 including a keyboard, a mouse, etc.; an output section 1307 including a display such as a cathode ray tube (CRT), a liquid crystal display (LCD), etc., and a speaker, etc.; a storage section 1308 including a hard disk, etc.; and a communication section 1309 including a network interface card such as a LAN card, a modem, etc. The communication section 1309 performs communication processing via a network such as the Internet.

Alternatively, the storage medium may be the ROM 1302, a hard disk included in the storage section 1308, or the like, in which the program is stored and distributed to the user together with the device containing them.

[0108] The following will refer to Figures 14 to 17 Application examples according to the present disclosure are described.

[0109] Application examples for base stations

[0110] First application example

[0111] Fig.14 14 is a block diagram showing a first example of a schematic configuration of a gNB to which the technology of the present disclosure can be applied. The gNB 1400 includes a plurality of antennas 1410 and a base station device 1420. The base station device 1420 and each antenna 1410 can be connected to each other via an RF cable. In one implementation, the gNB 1400 (or base station device 1420) herein can correspond to the above-mentioned electronic device 300A.

[0112] Each of the antennas 1410 includes a single or multiple antenna elements (such as multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna) and is used for the base station device 1420 to transmit and receive wireless signals. Fig.14 As shown, gNB 1400 may include multiple antennas 1410. For example, multiple antennas 1410 may be compatible with multiple frequency bands used by gNB 1400.

[0113] The base station device 1420 includes a controller 1421 , a memory 1422 , a network interface 1423 , and a wireless communication interface 1425 .

[0114] The controller 1421 may be, for example, a CPU or a DSP, and operates various functions of the higher layers of the base station device 1420. For example, the controller 1421 generates a data packet based on the data in the signal processed by the wireless communication interface 1425, and transmits the generated packet via the network interface 1423. The controller 1421 may bundle data from a plurality of baseband processors to generate a bundled packet, and transmit the generated bundled packet. The controller 1421 may have a logical function to perform the following control: the control may be such as radio resource control, radio bearer control, mobility management, admission control, and scheduling. The control may be performed in conjunction with a nearby gNB or core network node. The memory 1422 includes a RAM and a ROM, and stores programs executed by the controller 1421 and various types of control data (such as a terminal list, transmission power data, and scheduling data).

[0115] The network interface 1423 is a communication interface for connecting the base station device 1420 to the core network 1424. The controller 1421 can communicate with the core network node or another gNB via the network interface 1423. In this case, the gNB 1400 and the core network node or other gNBs can be connected to each other through logical interfaces (such as S1 interfaces and X2 interfaces). The network interface 1423 can also be a wired communication interface or a wireless communication interface for a wireless backhaul line. If the network interface 1423 is a wireless communication interface, the network interface 1423 can use a higher frequency band for wireless communication compared to the frequency band used by the wireless communication interface 1425.

[0116] The wireless communication interface 1425 supports any cellular communication scheme (such as long term evolution (LTE) and LTE-Advanced), and provides wireless connection to a terminal located in the cell of the gNB 1400 via the antenna 1410. The wireless communication interface 1425 may generally include, for example, a baseband (BB) processor 1426 and an RF circuit 1427. The BB processor 1426 may perform, for example, encoding / decoding, modulation / demodulation, and multiplexing / demultiplexing, and perform various types of signal processing of layers (such as L1, medium access control (MAC), radio link control (RLC), and packet data convergence protocol (PDCP)). Instead of the controller 1421, the BB processor 1426 may have part or all of the above-mentioned logical functions. The BB processor 1426 may be a memory storing a communication control program, or a module including a processor configured to execute a program and related circuits. Updating the program may change the function of the BB processor 1426. The module may be a card or a blade inserted into a slot of the base station device 1420. Alternatively, the module may also be a chip mounted on a card or a blade. Meanwhile, the RF circuit 1427 may include, for example, a mixer, a filter, and an amplifier, and transmit and receive wireless signals via the antenna 1410. Fig.14 An example is shown in which one RF circuit 1427 is connected to one antenna 1410 , but the present disclosure is not limited to this illustration, and one RF circuit 1427 may be connected to a plurality of antennas 1410 at the same time.

[0117] like Fig.14 As shown, the wireless communication interface 1425 may include multiple BB processors 1426. For example, the multiple BB processors 1426 may be compatible with multiple frequency bands used by the gNB 1400. Fig.14 As shown, the wireless communication interface 1425 may include multiple RF circuits 1427. For example, the multiple RF circuits 1427 may be compatible with multiple antenna elements. Fig.14 An example is shown in which the wireless communication interface 1425 includes a plurality of BB processors 1426 and a plurality of RF circuits 1427 , but the wireless communication interface 1425 may also include a single BB processor 1426 or a single RF circuit 1427 .

[0118] Second application example

[0119] Fig.1515 is a block diagram showing a second example of a schematic configuration of a gNB to which the technology of the present disclosure can be applied. The gNB 1530 includes a plurality of antennas 1540, a base station device 1550, and an RRH 1560. The RRH 1560 and each antenna 1540 can be connected to each other via an RF cable. The base station device 1550 and the RRH 1560 can be connected to each other via a high-speed line such as an optical fiber cable. In one implementation, the gNB 1530 (or base station device 1550) herein may correspond to the electronic device 300A described above.
