[0034] Example Wireless Communication System

[0035] Figure 1 shows an example block diagram of a wireless communication system according to an embodiment of the present disclosure. It should be noted that Figure 1 only shows one of many types and possible arrangements of wireless communication systems; the features of the present disclosure can be implemented in any of the various systems as needed.

[0036] As shown in FIG1 , a communication system 100 includes base stations 120A and 120B and terminal devices 110A, 110B to 110N. The base stations and the terminals may be configured to communicate via uplink and downlink channels. The base stations 120A and 120B may be configured to communicate with a network 130 (e.g., a core network of a cellular service provider, a telecommunications network such as a public switched telephone network (PSTN), and / or the Internet). Thus, the base stations 120A and 120B may facilitate communication between the terminal devices 110A to 110N and / or between the terminal devices 110A to 110N and the network 130.

[0037] 1 , the coverage area of ​​base stations 120A, 120B may be referred to as a cell. Base stations 120A, 120B may operate according to one or more radio access network technologies, thereby providing continuous or nearly continuous communication signal coverage to terminal devices 110A to 110N over a wide geographic area.

[0038] As shown in Figure 1, communication system 100 includes cloud 150 and mobile edge computing (MEC) nodes 140. Cloud 150 can provide services such as IaaS, PaaS, and SaaS to terminal devices through a connection with network 130. Computing resources can be deployed in cloud 150 and MEC 140 to support the computing needs of communication services (such as communication and computing convergence services).

[0039] 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 NR user plane and control plane protocols for termination with terminal devices; an ng-eNB is a node defined for compatibility with 4G LTE communication systems. It may be an upgrade of the evolved Node B (eNB) of the LTE radio access network, providing Evolved Universal Terrestrial Radio Access (E-UTRA) user plane and control plane protocols for termination with UEs. Furthermore, examples of base stations may include, but are not limited to, at least one of a base transceiver station (BTS) and a base station controller (BSC) in a GSM system; at least one of a radio network controller (RNC) and a Node B in a WCDMA system; an access point (AP) in a WLAN or WiMAX system; and corresponding network nodes in future or developing communication systems. Some of the functions of the base station herein may also be implemented as an entity that controls communications in D2D, M2M, and V2X scenarios, or as an entity that performs spectrum coordination in cognitive radio communication scenarios.

[0040] In the present disclosure, terminal devices may have the full breadth of their usual meanings, for example, terminal devices may be mobile stations (MS), user equipment (UE), etc. Terminal devices may be implemented as, for example, mobile phones, handheld devices, media players, computers, laptops, tablet computers, on-board units (OBU) or vehicles, roadside units (RSU), wearable devices, Internet of Things (IoT) devices, or virtually any type of wireless device. In some cases, terminal devices may communicate using multiple wireless communication technologies. For example, terminal devices may be configured to communicate using one or more of GSM, UMTS, CDMA2000, WiMAX, LTE, LTE-A, WLAN, NR, Bluetooth, etc.

[0041] Example beam scanning and pairing process

[0042] High-frequency millimeter-wave communications are a key area of ​​mobile communications. Compared to low-frequency transmission, millimeter-wave transmissions have greater path loss and poorer reflection and diffraction capabilities. Therefore, larger antenna arrays are typically used to maximize beamforming gain. Beamforming includes fully digital beamforming. In this method, each antenna in the array has an independent digital link channel, enabling baseband control of the digital signal's amplitude and phase. Due to the limited size of millimeter-wave antenna arrays, hybrid beamforming—a combination of analog and digital beamforming—is more practical due to factors such as hardware complexity, cost, and power consumption.

[0043] When using analog beamforming for link transmission, to achieve optimal beamforming performance, transmit / receive beam scanning is typically used to search for matching transmit / receive beam pairs. A base station can only form a limited number of analog beams at a time (the number of beams depends on the number of digital ports, with each digital port corresponding to one beam), and these beamwidths are narrow, typically covering only a portion of the cell. Therefore, initial access synchronization signals and system broadcast messages must be broadcast throughout the cell to achieve full cell coverage. In other words, the formed beams sequentially cover different areas of the cell to achieve complete cell coverage.

[0044] Figure 2 shows a schematic diagram of beam scanning and pairing according to an embodiment of the present disclosure. In the example of Figure 2, beam scanning and pairing are implemented 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, and reports the beam scanning results to the base station. For example, the terminal device measures the reference signal reception power sent through multiple transmit beams, and reports the transmit beam with the best reception performance (for example, transmit beam A1 with the highest reference signal reception power) to the base station. Accordingly, the base station determines transmit beam A1 as the matching beam for the terminal device; the terminal device selects the receive beam with the best reception performance (for example, receive beam B1 with the highest reference signal received power) as the matching beam for the base station. The base station's transmit beam A1 and the terminal's receive beam B1 are paired transmit and receive beams. During the P1 process, assuming the base station has M transmit beams and the terminal device has N receive beams, beam scanning requires M x N transmissions.

[0045] During the P2 process, the base station forms multiple narrow beams near the transmit beam A1. For example, forming multiple narrow beams near the transmit beam A1 includes forming narrow beams within the coverage range and adjacent range of the transmit beam A1. The base station sends a reference signal through multiple narrow transmit beams so as to perform beam subdivision between the multiple narrow transmit beams. Accordingly, the terminal device receives the reference signal sent by the base station through the multiple narrow transmit beams through the wide beam B1, and reports the beam scanning results to the base station. For example, the terminal device measures the reference signal reception power sent through the multiple narrow transmit beams respectively, and reports the transmit beam with the best reception performance (e.g., transmit beam A2 with the highest reference signal reception power) to the base station. Accordingly, the base station determines the transmit beam A2 as the beam that matches the terminal device.

[0046] During the P3 process, the base station transmits a reference signal through the narrow transmit beam A2 determined in the P2 process. Accordingly, 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 received power through multiple narrow receive beams respectively, and determines the narrow receive beam with the best reception performance (for example, the narrow receive beam B2 with the highest reference signal received 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 paired transmit and receive beams.

[0047] In embodiments of the present disclosure, Integrated Sensing and Communication (ISAC) signals can be used in beam management in addition to or as an alternative to traditional reference signals. Leveraging the sensory measurement capabilities of base stations and user devices, matching transmit and receive beam pairs between base stations and user devices can be efficiently determined in a shorter time using fewer beam scans.

[0048] Example electronic device

[0049] FIG3A illustrates an example electronic device that can implement a base station (e.g., base stations 120A and 120B) according to embodiments of the present disclosure. Electronic device 300A may include various units to implement various embodiments of beam management according to the present disclosure. In the example of FIG3A , electronic device 300A includes a transceiver unit 302A and a sensing and processing unit 304A. The various operations described below in connection with base stations or beam management may be implemented by units 302A to 304A of electronic device 300A or other possible units.

[0050] In one embodiment, the transceiver unit 302A may be configured to transmit a synaesthesia-integrated signal via a first plurality of transmit beams, and in response to transmitting the synaesthesia-integrated signal, receive a first set of echo signals corresponding to a terminal device (e.g., any 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 set of echo signals. The transceiver unit 302A may further be configured to send a first notification to the terminal device, enabling the terminal device to determine a first receive beam (e.g., beam A1) that matches the base station.

[0051] In one embodiment, the transceiver unit 302A may be configured to establish a beam pair link with a terminal device (e.g., any of the terminal devices 110A to 110N) using a first transmit beam (e.g., beam B2) and transmit a synaesthesia integration signal at a first transmit frequency via the first transmit beam. The transceiver unit 302A may be further configured to receive a first set of echo signals corresponding to the terminal device in response to transmitting the synaesthesia integration signal. The sensing and processing unit 304A may be configured to obtain a mobile state of the terminal device based on the first set of echo signals. The sensing and processing unit 304A may be further configured to determine a receiving beam to be tracked for the terminal device (e.g., a beam other than beam B2) based on the mobile state of the terminal device.

[0052] 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 function as a communication device as a whole.

[0053] FIG3B illustrates an example electronic device that can implement a terminal device (e.g., any of terminal devices 110A to 110N) according to an embodiment of the present disclosure. Electronic device 300B may include various units to facilitate implementation of various embodiments of beam management according to the present disclosure. In the example of FIG3B , electronic device 300B includes a transceiver unit 302B and a processing unit 304B. The various operations described below in conjunction with the terminal device or beam management may be implemented by units 302B to 304B of electronic device 300B or other possible units.

[0054] In one embodiment, processing unit 304B may be configured to determine, based on a first notification received from a base station (e.g., base station 120A or 120B), a first receive beam that matches the base station from a first plurality of receive beams. Transceiver unit 302B may be configured to receive, via the first plurality of receive beams, a synaesthesia signal transmitted by the base station via a transmit beam. Processing unit 304B may be further configured to verify, based on measurements of the synaesthesia signal, whether the first receive beam is the optimal receive beam that matches the base station.

[0055] 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 receive beam. The processing unit 304B may be configured to initiate or stop sensing the synaesthesia signal transmitted by the base station based on the first notification received from the base station. The transceiver unit 302B may be further configured to provide feedback of the sensing result to the base station.

[0056] 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 function as a communication device as a whole.

[0057] It should be understood that the above-mentioned various 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 various units can be implemented as independent physical entities, or they 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), 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.

[0058] Perception-assisted beam management

[0059] FIG4 illustrates example operations of sensing-assisted beam management according to an embodiment of the present disclosure. The example operations 400 may be implemented by a base station (eg, base stations 120A and 120B in FIG1 ) or the electronic device 300A.

[0060] As shown in FIG4 , example operations 400 include, for example, base station 120A transmitting a synaesthesia-integrated signal via multiple transmit beams (402), and receiving a set of echo signals corresponding to a terminal device (e.g., terminal device 110A in FIG1 ) in response to the transmitted synaesthesia-integrated signal (404). It should be noted that in a high-frequency band scenario, the echo signals primarily include reflected signals corresponding to terminal device 110A. Example operations 400 also include base station 120A estimating a location of terminal device 110A based on the set of echo signals (406).

[0061] It should be understood that through operations 402 to 406, base station 120A can achieve location awareness of terminal device 110A based on the synaesthesia signal. Depending on the transmission beam used by base station 120A to send the synaesthesia signal, the location of terminal device 110A relative to base station 120A can be perceived with varying degrees of accuracy. For example, when using a wider beam (e.g., similar to beam A1 in FIG. 2 ), base station 120A can perceive the approximate location of terminal device 110A. When using a narrower beam (e.g., similar to beam A2 in FIG. 2 ), base station 120A can perceive a more precise location of terminal device 110A. In one embodiment, base station 120A can perceive at least one of the distance, velocity, or angle of terminal device 110A relative to base station 120A based on the time delay, Doppler frequency, and phase difference information of the set of echo signals. Base station 120A can further estimate the location of terminal device 110A relative to base station 120A based on at least one of the distance, velocity, or angle of terminal device 110A relative to base station 120A.

[0062] 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 velocity and λ is the signal wavelength. Target angle measurement primarily utilizes overlapping antenna beams or multiple phase centers. The angle of terminal device 110A is measured by measuring the intensity differences between echoes output from different beams or the phase differences between target echoes output from multiple phase centers.

[0063] As shown in FIG4 , example operations 400 also include 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 a beam scanning or beam tracking process. In one embodiment, the base station 120A can determine a transmit beam and / or receive beam to be 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 a receive beam to be tracked for the terminal device 110A based on the estimated position of the terminal device 110A, as described in detail below.

[0064] FIG5 illustrates an example process for beam scanning and pairing according to an embodiment of the present disclosure. Example process 500 may be performed between base station 120 (or electronic device 300A) and terminal device 110 (or electronic device 300B). For example, base station 120 may be any of base stations 120A and 120B in FIG1 , and terminal device 110 may be any of terminal devices 110A to 110N in FIG1 . In an embodiment, example process 500 may be used to implement the P1 process of beam scanning.

[0065] As shown in FIG5 , at 502, the base station 120 transmits a synaesthesia-integrating signal via a first plurality of transmit beams. The first plurality of transmit beams are relatively wide beams, such as beam A1 in FIG2 . In one embodiment, transmitting the synaesthesia-integrating signal via the first plurality of transmit beams includes transmitting the synaesthesia-integrating signal only in a single cycle of the first plurality of transmit beams (rather than M×N cycles as in FIG2 ).

[0066] At 504, in response to transmitting the synaesthesia integration signal, base station 120 receives a first set of echo signals corresponding to terminal device 110. In one embodiment, upon receiving the synaesthesia integration signal, terminal device 110 may send a confirmation message to base station 120. For example, the confirmation message may indicate that the synaesthesia integration signal has been received. Upon receiving the confirmation message, base station 120 identifies the echo signals received within a specific time window before and after receiving the confirmation message as a set of echo signals corresponding to terminal device 110. For example, depending on actual needs, the time window size may be set to 10ms, 20ms, 50ms, 100ms, or 200ms, etc.

[0067] At 506, after receiving the first set 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 perception. Since the first set of transmit beams is a relatively wide beam, the first accuracy may be relatively low, and the base station 120 therefore 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 may determine a first transmit beam (e.g., beam A1 in FIG. 2 ) that matches the terminal device 110 from the first set of multiple transmit beams. The base station 120 may also determine a first receive beam (e.g., beam B1 in FIG. 2 ) on the terminal device 110 side that matches the base station 120 based on the estimated position of the terminal device 110.

[0068] At 508, base station 120 sends a first notification to terminal device 110 to enable terminal device 110 to determine a receive beam that matches base station 120. In one embodiment, if base station 120 has already determined a first receive beam that matches base station 120 on the terminal device 110 side, base station 120 may indicate the first receive beam in the first notification. In another embodiment, base station 120 may indicate the position of terminal device 110 relative to base station 120 in the first notification to facilitate terminal device 110 to determine the first receive beam that matches base station 120.

[0069] It should be understood that in example process 500, the synaesthesia integration signal may be transmitted only in a single cycle of at least the first plurality of transmit beams, thereby obtaining the transmit beam and receive beam paired between base station 120 and terminal device 110 based on the perception of the location of terminal device 110. Compared to the traditional P1 process that requires M×N transmit and receive beam scans, for example, the example process 500 is more efficient and can achieve beam scanning results equivalent to the P1 process in a shorter time and with lower processing overhead.

[0070] FIG6 illustrates another example process for beam scanning and pairing according to an embodiment of the present disclosure. Example process 600 may be performed between base station 120 (or electronic device 300A) and terminal device 110 (or electronic device 300B). For example, base station 120 may be any of base stations 120A and 120B in FIG1 , and terminal device 110 may be any of terminal devices 110A to 110N in FIG1 . In an embodiment, example process 600 may be used to implement the P2 and P3 processes of beam scanning.

[0071] As shown in FIG6 , at 602, base station 120 transmits a synaesthesia-integrating signal via a second plurality of transmit beams. The second plurality of transmit beams are narrower beams, such as beam A2 in FIG2 . In one embodiment, the second plurality of transmit beams are formed by base station 120 near the first transmit beam determined in example process 500 . For example, the second plurality of transmit beams may be formed within the coverage area of ​​the first transmit beam or further within the vicinity of the first transmit beam. In one embodiment, transmitting the synaesthesia-integrating signal via the second plurality of transmit beams includes transmitting the synaesthesia-integrating signal only during a single cycle of the second plurality of transmit beams.

[0072] At 604, in response to transmitting the synaesthesia signal, base station 120 receives a second set of echo signals corresponding to terminal device 110. In one embodiment, upon receiving the synaesthesia signal, terminal device 110 sends a confirmation message to base station 120. For example, the confirmation message may indicate that the synaesthesia signal has been received. Upon receiving the confirmation message, base station 120 identifies the echo signals received within a specific time window before and after receiving the confirmation message as a set of echo signals corresponding to terminal device 110. For example, the time window may be 10ms, 20ms, 50ms, 100ms, or 200ms, depending on actual needs.

[0073] At 606, after receiving the second set of echo signals corresponding to terminal device 110, base station 120 estimates the position of terminal device 110 with a second accuracy based on perception. Because the second set of transmit beams is a narrower beam, the second accuracy can be relatively high, and base station 120 thus obtains a finer position of terminal device 110. The specific operation of estimating the finer position of terminal device 110 can be understood with reference to operation 408. In an embodiment, example process 600 can be performed after estimating the approximate position of terminal device 110 in example process 500 to re-estimate the finer position of terminal device 110. In one embodiment, based on the estimated position of terminal device 110, base station 120 can determine a second transmit beam (e.g., beam A2 in FIG. 2 ) that matches terminal device 110 from the second set of multiple transmit beams. Base station 120 may also determine a second receive beam (e.g., beam B2 in FIG. 2 ) on the terminal device 110 side that matches base station 120 based on the estimated position of terminal device 110.

[0074] In one embodiment, the terminal device 110 can receive and measure the synaesthesia integration signal sent at 602 through the first receiving beam (e.g., beam B1 in FIG. 2 ) determined in the P1 process to match the base station 120. 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 a corresponding measurement report to the base station 120 for the second set of multiple transmit beams. It should be noted that compared to the base station 120 sensing based on the echo signal received at 604, the terminal device 110 may take longer to measure the reference signal carried by the synaesthesia integration signal. Therefore, the narrower transmit beam that matches the terminal device 110 on the base station 120 side can be determined first based on the echo signal. Afterwards, the base station 120 can verify whether the determined transmit beam is the best beam that matches 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 not only quickly determine the matching transmit beam, but also ensure that the determined transmit beam is the best matching beam.

[0075] 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 (e.g., beam B2 in FIG. 2 ). In one embodiment, when the base station 120 has determined the second receiving beam that matches the base station 120 on the terminal device 110 side, 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 that matches the base station 120 on the terminal device 110 side can be determined accordingly.

[0076] In one embodiment, after determining a matching receive beam for base station 120, terminal device 110 can additionally measure a reference signal from base station 120 using its multiple receive beams to verify whether the determined matching receive beam is optimal and make adjustments if necessary. This operation is efficient, allowing for rapid determination of a matching receive beam while ensuring that the determined receive beam is the optimal matching beam.

[0077] It should be understood that in example process 600, the synaesthesia integration signal may be transmitted only in a single cycle of at least the second plurality of transmit beams, thereby obtaining a narrower transmit beam and receive beam paired between base station 120 and terminal device 110 based on the perception of the finer location of terminal device 110. Compared to traditional P2 and P3 processes, example process 600 is more efficient and can achieve beam scanning results equivalent to those of P2 and P3 processes in a shorter time and with lower processing overhead.

[0078] Figure 7 shows an example of the transmission configuration information TCI state according to an embodiment of the present disclosure. As shown in Figure 7, 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 CSI-RS or 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 the example processes 500 and 600 may include a TCI state.

[0079] In one embodiment, the base station 120 may determine the receive beam of the terminal device 110 based on the estimated position of the terminal device 110, and the reference signal corresponding to the receive 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, for example, in a previous beam scanning operation 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 reception 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.

[0080] In one embodiment, the TCI state may be configured via RRC signaling. The TCI state may also be configured via RRC signaling and activated via MAC-CE. The TCI state may also be configured via RRC signaling, activated via MAC-CE, and indicated via DCI.

[0081] FIG8 illustrates an example process for beam tracking according to an embodiment of the present disclosure. Example process 800 may be performed between base station 120 (or electronic device 300A) and terminal device 110 (or electronic device 300B). For example, base station 120 may be any of base stations 120A and 120B in FIG1 , and terminal device 110 may be any of terminal devices 110A to 110N in FIG1 .

[0082] As shown in FIG8 , at 802, base station 120 and terminal device 110 establish a beam pair link using paired transmit and receive beams determined during beam scanning. In one embodiment, the paired transmit and receive beams are narrow beams, such as beams A2 and B2 in FIG2 . It should be understood that once a beam pair link has been established, base station 120 and terminal device 110 need to track the performance of other beams so that a new beam pair link can be quickly established using the other beams if the performance of the currently paired narrow beam degrades.

[0083] At 804, base station 120 transmits a synaesthesia integration signal at a first transmission frequency via the established beam pair link. The first transmission frequency can be a relatively low frequency, allowing base station 120 to transmit the synaesthesia integration signal at a period of, for example, 50 ms, 100 ms, 200 ms, or 500 ms. At 806, in response to transmitting the synaesthesia integration signal, base station 120 receives a set of echo signals corresponding to terminal device 110.

[0084] At 808, based on the set of echo signals, base station 120 determines the mobility state of terminal device 110 and a receive beam to be tracked for terminal device 110. In one embodiment, base station 120A may sense at least one of the distance, velocity, or angle of terminal device 110A relative to base station 120A based on the time delay, Doppler frequency, and phase difference information of the set of echo signals. Base station 120A may further estimate the mobility state of terminal device 110A relative to base station 120A based on at least one of the distance, velocity, or angle of terminal device 110A relative to base station 120A. In one embodiment, a receive beam to be tracked for terminal device 110 may be determined based on the mobility state of terminal device 110.

[0085] Based on the perception of the mobility state of terminal device 110, the rate of change of the mobility state of terminal device 110 can be determined. In one embodiment, the rate of change of the mobility state may relate to the speed and / or acceleration of terminal device 110. It should be noted that a higher speed means faster changes in the position of terminal device 110, while a higher acceleration means less stable changes in the position of terminal device 110. Either situation may cause the current beam link between base station 120 and terminal device 110 to fail. Therefore, more frequent tracking of the beam performance between base station 120 and terminal device 110 is required. Accordingly, when the rate of change of the mobility state is below a threshold, the position of terminal device 110 changes relatively slowly. Therefore, operations 802 to 808 may be repeatedly performed to transmit the synaesthesia integration signal at a lower first frequency and perform beam management. When the rate of change of the mobility state is above the threshold, the position of terminal device 110 changes relatively quickly. Therefore, more frequent and accurate updates of the mobility state and position information of terminal device 110 are required to maintain tracking of the receive beam of terminal device 110.

[0086] At 810, in response to determining that the rate of change in the mobility state of terminal device 110 is greater than a threshold, base station 120 transmits a synaesthesia integration signal at a second transmission frequency. The second transmission frequency is higher than the first transmission frequency, allowing base station 120 to transmit the synaesthesia integration signal at a period of, for example, 20ms, 40ms, 60ms, or 80ms. At 812, in response to transmitting the synaesthesia integration signal, base station 120 receives a set of echo signals corresponding to terminal device 110. Due to the higher transmission frequency of the synaesthesia integration signal, base station 120 can collect this set of echo signals in a shorter period of time. At 814, based on this set of echo signals, base station 120 can quickly determine the mobility state of terminal device 110 and the receiving beam to be tracked by terminal device 110. Thereafter, based on the relationship between the rate of change in the mobility state of terminal device 110 and the threshold, base station 120 can select whether to transmit the synaesthesia integration signal at the first frequency or the second frequency.

[0087] FIG9 illustrates another example process for beam tracking according to an embodiment of the present disclosure. Example process 900 may be performed between base station 120 (or electronic device 300A) and terminal device 110 (or electronic device 300B). For example, base station 120 may be any of base stations 120A and 120B in FIG1 , and terminal device 110 may be any of terminal devices 110A to 110N in FIG1 . Compared to example process 800, example process 900 may more accurately update the mobile state and location information of terminal device 110 based on measurement reports from terminal device 110 when the rate of change of the mobile state of terminal device 110 exceeds a threshold.

[0088] Operations 902 to 908 can be understood with reference to operations 802 to 808 in FIG8 . As shown in FIG9 , at 910 , in response to determining that the rate of change of the mobility state of terminal device 110 is greater than a threshold, base station 120 transmits a synaesthesia integration signal and a notification message to terminal device 110. Upon receiving the notification message, at 911 , terminal device 110 may initiate a perception measurement of the synaesthesia integration signal transmitted by base station 120, and then feed back the perception measurement result to base station 120.

[0089] In one embodiment, the terminal device 110 performs a perceptual measurement on the synaesthesia integrated signal, including performing a multipath measurement on the perceptual signal. The 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 sm (τ) , the received signal can be expressed as:

[0090] Among them, X j,(m) (t:V (j) ) is the transmitted signal of the jth path. A spatial generalized alternating algorithm is used to iteratively optimize the estimated parameters for each path by alternately optimizing the delay, Doppler, signal coefficient, and angle of arrival components. For example, spatial alternating generalized expectation (SAGE) maximization can be used to reduce computational complexity. By alternating optimization of the estimated parameters for each path, the convergence rate of the maximization step is improved.

[0091] At 912, in response to transmitting the synaesthesia integration signal, base station 120 receives a set of echo signals corresponding to terminal device 110. At 913, base station 120 receives a measurement report from terminal device 110. At 914, based on the set of echo signals, base station 120 is able to determine the mobility state of terminal device 110 and the receive beam to be tracked by terminal device 110. Furthermore, the base station can also determine the mobility state of terminal device 110 and the receive beam to be tracked by terminal device 110 based on the measurement report. In one embodiment, base station 120 can mutually verify the results determined based on the set of echo signals and the perceptual measurement report, thereby improving the accuracy of the beam tracking operation.

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

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

[0094] FIG10 illustrates another example process for beam tracking according to an embodiment of the present disclosure. Example process 1000 may be performed between base station 120 (or electronic device 300A), terminal device 110 (or electronic device 300B), an access and mobility function (AMF) entity, and a sensing function (SF) entity. For example, base station 120 may be any of base stations 120A and 120B in FIG1 , and terminal device 110 may be any of terminal devices 110A to 110N in FIG1 .

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

[0096] As shown in Figure 10, at 1002, base station 120 obtains perception data based on its own perception or feedback from terminal device 110. At 1004, base station 110 provides the perception data to the SF entity via the AMF entity. At 1006, the SF entity processes the perception data. In one embodiment, the SF entity may perceive at least one of the distance, velocity, or angle of terminal device 110A relative to base station 120A based on the time delay, Doppler frequency, and phase difference information of the set of echo signals. The SF entity may further estimate the position of terminal device 110A relative to base station 120A based on at least one of the distance, velocity, or angle of terminal device 110A relative to base station 120A. At 1008, the SF entity provides the results of the perception data processing to base station 120 via the AMF entity. It should be understood that the SF function is only one example of a perception network element. In different implementations, the SF function may be implemented as a standalone entity or in conjunction with other entities.

[0097] Figure 11 shows a first example method for communication according to an embodiment of the present disclosure. The method can be performed by a terminal device (e.g., any one of 110A to 110N) or an electronic device 300B. As shown in Figure 11, 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 can be understood with reference to the description above regarding the terminal device or electronic device 300B.

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

[0099] The above describes various exemplary electronic devices and methods 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 implement more or fewer operations or functions than described. The operational steps of each method can also be combined with each other in any appropriate order to similarly implement more or fewer operations than described.

In addition, it should be understood that the above-mentioned series of processes and devices may also be implemented by software and / or firmware.

[0101] In addition, it should be understood that the above series of processes and devices can also be implemented through software and / or firmware. In the case of implementation through software and / or firmware, the program constituting the software is installed from a storage medium or network to a computer with a dedicated hardware structure, such as the general-purpose computer 1300 shown in Figure 13. When the various programs are installed, the computer can perform various functions, etc. Figure 13 shows 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.

[0102] 13 , 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 one another via a bus 1304. An input / output interface 1305 is also connected to the bus 1304.

[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 a ROM 1302, a hard disk included in the storage section 1308, or the like, in which the programs are stored and distributed to users together with the device containing them.

[0108] Application examples according to the present disclosure will be described below with reference to FIG. 14 to FIG. 17 .

[0109] Application examples for base stations

[0110] First application example

[0111] FIG14 is a block diagram illustrating a first example of a schematic configuration of a gNB to which the techniques of this disclosure may be applied. gNB 1400 includes multiple antennas 1410 and a base station device 1420. Base station device 1420 and each antenna 1410 may be connected to each other via an RF cable. In one implementation, gNB 1400 (or base station device 1420) may correspond to electronic device 300A described above.

[0112] Each antenna 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 base station device 1420 to transmit and receive wireless signals. As shown in Figure 14, 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 DSP, and operates various higher-layer functions of the base station device 1420. For example, the controller 1421 generates data packets based on the data in the signal processed by the wireless communication interface 1425 and transmits the generated packets via the network interface 1423. The controller 1421 may bundle data from multiple baseband processors to generate bundled packets and transmit the generated bundled packets. The controller 1421 may have logic functions for performing control such as radio resource control, radio bearer control, mobility management, admission control, and scheduling. This control may be performed in conjunction with a nearby gNB or core network node. The memory 1422 includes RAM and ROM and stores programs executed by the controller 1421 and various types of control data (such as terminal lists, 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 gNB can be connected to each other via a logical interface (such as an S1 interface and an X2 interface). The network interface 1423 can also be a wired communication interface or a wireless communication interface for wireless backhaul. If the network interface 1423 is a wireless communication interface, the network interface 1423 can use a higher frequency band for wireless communication than 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 connectivity to terminals located in the cell of the gNB 1400 via the antenna 1410. The wireless communication interface 1425 may typically include, for example, a baseband (BB) processor 1426 and RF circuitry 1427. The BB processor 1426 can perform various signal processing functions, such as encoding / decoding, modulation / demodulation, and multiplexing / demultiplexing, and performs various types of signal processing for layers such as Layer 1 (L1), Medium Access Control (MAC), Radio Link Control (RLC), and Packet Data Convergence Protocol (PDCP). In place of the controller 1421, the BB processor 1426 may perform some or all of the aforementioned logical functions. The BB processor 1426 may be a memory storing communication control programs, or a module including a processor configured to execute programs and associated circuitry. Program updates can modify the functionality of the BB processor 1426. This module may be a card or blade inserted into a slot in the base station device 1420. Alternatively, it may be a chip mounted on the card or blade. Meanwhile, the RF circuit 1427 may include, for example, a mixer, a filter, and an amplifier, and transmits and receives wireless signals via the antenna 1410. Although FIG14 shows an example in which one RF circuit 1427 is connected to one antenna 1410, the present disclosure is not limited to this illustration, and one RF circuit 1427 may be connected to multiple antennas 1410 at the same time.

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

[0118] Second application example

[0119] FIG15 is a block diagram illustrating a second example of a schematic configuration of a gNB to which the techniques of this disclosure can be applied. A gNB 1530 includes multiple 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.

[0120] Each antenna 1540 includes a single or multiple antenna elements (such as multiple antenna elements included in a MIMO antenna) and is used for RRH 1560 to transmit and receive wireless signals. As shown in Figure 15, gNB 1530 may include multiple antennas 1540. For example, multiple antennas 1540 may be compatible with multiple frequency bands used by gNB 1530.

[0121] Base station device 1550 includes a controller 1551, a memory 1552, a network interface 1553, a wireless communication interface 1555, and a connection interface 1557. Controller 1551, memory 1552, and network interface 1553 are the same as controller 1421, memory 1422, and network interface 1423 described with reference to FIG.

[0122] The wireless communication interface 1555 supports any cellular communication scheme (such as LTE and LTE-Advanced) and provides wireless communication to terminals located in the sector corresponding to the RRH 1560 via the RRH 1560 and the antenna 1540. The wireless communication interface 1555 may generally include, for example, a BB processor 1556. The BB processor 1556 is identical to the BB processor 1426 described with reference to FIG. 14 , except that the BB processor 1556 is connected to the RF circuit 1564 of the RRH 1560 via the connection interface 1557. As shown in FIG. 15 , the wireless communication interface 1555 may include multiple BB processors 1556.
