Description

Beam measurement method and communication device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on January 26, 2024, with application number 202410121915.1, and priority to the Chinese patent application entitled “A Beam Measurement Method and Communication Device”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a beam measurement method and a communication device. Background Art

[0003] Network devices and terminal devices require beam alignment for subsequent data transmission. However, to maintain beam alignment between the network and terminal devices, the terminal device must measure the beam based on reference signals sent by the network device and report the measurement results to the network device, which then indicates the serving beam. Furthermore, to ensure mobility support, this process typically needs to be continuous, resulting in extremely high indication overhead. Summary of the Invention

[0004] The present application provides a beam measurement method and a communication device, thereby reducing the indication overhead of real-time beam measurement to improve communication efficiency.

[0005] In a first aspect, a beam measurement method is provided. The method can be performed by an apparatus (e.g., a communication device). The apparatus can be a device (e.g., a terminal device or a network device), or a component of a device (e.g., a chip or a chip system or a circuit), which is not limited in this application. The following description mainly uses a communication device as an example.

[0006] The method may include: receiving first indication information, the first indication information indicating a first range within a candidate position set, the candidate position set including multiple candidate positions, the multiple candidate positions corresponding one-to-one to multiple beams; performing beam measurement on the beams corresponding to the candidate positions within the first range; and sending the results of the beam measurement.

[0007] Based on the above solution, the beam to be measured can be indicated by indicating a range (such as the first range) in the candidate position set. Specifically, there are multiple candidate positions in the candidate position set, each corresponding to a beam. In this way, by indicating a range, all beams within the range can be indicated. Compared with indicating each beam individually, the above solution can reduce indication overhead.

[0008] In combination with the first aspect, in certain implementations of the first aspect, in a perception scenario, the communication device determines a beam to be measured within a first range based on a perception result.

[0009] Based on the above solution, the communication device performs beam measurement based on the perception results of the reflector, avoiding the problem of excessive overhead caused by measuring all beams, thereby improving communication efficiency.

[0010] In combination with the first aspect, in some implementations of the first aspect, the method further includes: receiving a reference signal, where the reference signal is sent using a beam within the first range.

[0011] Based on the above solution, the communication device receives the reference signal sent based on the beam within the first range, thereby improving communication efficiency.

[0012] In conjunction with the first aspect, in certain implementations of the first aspect, the method further includes: receiving second indication information, the second indication information indicating a candidate position set, wherein the candidate position set indicates at least one parameter of the beam.

[0013] It should be understood that the candidate position set may indicate a greater or lesser number of parameters.

[0014] Based on the above solution, the communication device determines a candidate position set by receiving the second indication information. The communication device can determine a first range based on the candidate position set and the first indication information, thereby determining the beam to be measured.

[0015] In combination with the first aspect, in certain implementations of the first aspect, the intervals between every two adjacent candidate positions in the candidate position set are the same; or, the candidate positions in the candidate position set are uniformly distributed.

[0016] Based on the above scheme, the candidate positions in the candidate position set are uniformly distributed, which not only makes it possible to discretize the relevant parameters of the beam through the candidate position set, but also because the candidate positions are uniformly distributed, the content of the indication can be simplified when indicating the first range, thereby reducing the indication overhead during the beam measurement process.

[0017] In combination with the first aspect, in some implementations of the first aspect, the candidate position set is used to represent at least one parameter of different beams, where different beams have different beam widths.

[0018] In combination with the first aspect, in certain implementations of the first aspect, the candidate position set has numbers that correspond one-to-one to the candidate positions, and the first indication information indicates the set of candidate position numbers within the first range in the candidate position set, wherein the specific method of numbering the candidate positions is not limited.

[0019] In another possible implementation, the first indication information includes at least one of the following:

[0020] (1) the number of the starting candidate position in the first range, the number of the ending candidate position in the first range; or

[0021] (2) The number of the starting candidate position in the first range, and the number of candidate positions in the first range.

[0022] Based on the above scheme, the first indication information can indicate the number of the candidate positions within the first range. For example, by indicating the number and quantity of the starting position, the communication device can determine all the candidate positions within the first range based on the indication, that is, determine the corresponding beam to be measured within the first range.

[0023] In combination with the first aspect, in some implementations of the first aspect, the first range is a circle, and the first indication information includes the center position and / or radius of the circular first range.

[0024] In another possible implementation, the first range is a square, and the first indication information includes at least one of the following: the position of a corner of the square, the length of the square, the width of the square, the center position of the length of the square, and the center position of the width of the square.

[0025] It should be understood that the first range determined by the communication device according to the first indication information can be a variety of shapes such as circle, square, ellipse, parallelogram, etc., and this application does not limit this.

[0026] Based on the above scheme, the first indication information can indicate the shape, position and size of the first range. For example, by indicating the center and radius of the circular first range, the communication device can determine all candidate positions within the first range based on the indication, that is, determine the corresponding beam to be measured within the first range.

[0027] In combination with the first aspect, in certain implementations of the first aspect, after the communication device determines the first range according to the first indication information, it numbers the candidate positions within the first range. This application does not specifically limit the specific numbering method.

[0028] Based on the above solution, the communication device numbers the candidate positions within the first range, that is, numbers the beams to be measured corresponding to the candidate positions within the first range, thereby reducing signaling overhead during the communication process.

[0029] In conjunction with the first aspect, in certain implementations of the first aspect, the candidate position set is used to mark spatial angle information of a beam, where the spatial angle information of the beam is used to determine the spatial angle of the beam. That is, each candidate position in the candidate position set corresponds to at least one parameter of a beam, where the at least one parameter includes a zenith angle and / or an azimuth angle.

[0030] Based on the above solution, the candidate position set is used to discretize the spatial angle information of the beam, while reducing the subsequent indication overhead of the first range.

[0031] In combination with the first aspect, in certain implementations of the first aspect, the result of the beam measurement includes at least one of the following: the candidate position number corresponding to the beam within the first range, the number of the beam measurement resource corresponding one-to-one to the beam within the first range, and the signal strength of the beam within the first range.

[0032] Based on the above solution, the communication device reports the result of beam measurement of the beam to be measured corresponding to the candidate position within the first range, thereby reducing signaling overhead and reporting overhead.

[0033] In combination with the first aspect, in certain implementations of the first aspect, the measurement resources in the beam measurement resource set are numbered, and this application does not limit the specific numbering method.

[0034] In combination with the first aspect, in certain implementations of the first aspect, the communication device determines the number of beam measurement resources based on the number of candidate positions within the first range.

[0035] Based on the above solution, the communication device configures beam measurement resources for the beams to be measured corresponding to the candidate positions within the first range and numbers them, and selects transmission based on the number during the communication process, thereby reducing signaling overhead.

[0036] In a second aspect, a beam measurement method is provided, which can be performed by an apparatus (e.g., a communication apparatus). The apparatus can be a device (e.g., a terminal device or a network device), or a component of a device (e.g., a chip or a chip system or a circuit), which is not limited in this application.

[0038] In combination with the second aspect, in certain implementations of the second aspect, in a perception scenario, the communication device determines a beam to be measured within the first range based on a perception result.

[0039] In combination with the second aspect, in some implementations of the second aspect, the method further includes: sending a reference signal using a beam within the first range.

[0040] In conjunction with the second aspect, in certain implementations of the second aspect, the method further includes: sending second indication information, where the second indication information indicates a set of candidate positions, wherein the set of candidate positions indicates at least one parameter of the beam.

[0041] It should be understood that the candidate position set may indicate a greater or lesser number of parameters.

[0042] In combination with the second aspect, in certain implementations of the second aspect, the intervals between every two adjacent candidate positions in the candidate position set are the same; or, the candidate positions in the candidate position set are uniformly distributed.

[0043] In combination with the second aspect, in certain implementations of the second aspect, the candidate position set is used to represent at least one parameter of different beams, where different beams have different beam widths.

[0044] In combination with the second aspect, in certain implementations of the second aspect, the candidate position set configured by the communication device has numbers that correspond one-to-one to the candidate positions, and the first indication information indicates the set of candidate position numbers within the first range in the candidate position set, wherein the specific method of numbering the candidate positions is not limited.

[0046] (1) The number of the starting candidate position in the first range, and the number of the ending candidate position in the first range;

[0047] (2) The number of the starting candidate position in the first range, and the number of candidate positions in the first range.

[0048] In combination with the second aspect, in some implementations of the second aspect, the first range is a circle, and the first indication information includes the center position and / or radius of the circular first range.

[0050] It should be understood that the first range determined by the indication parameter configured by the communication device can be a variety of shapes such as circle, square, ellipse, parallelogram, etc., and this application does not limit this.

[0051] In combination with the second aspect, in certain implementations of the second aspect, after the communication device determines the first range based on the beam to be measured, it numbers the candidate positions within the first range. This application does not specifically limit the specific numbering method.

[0052] In conjunction with the second aspect, in certain implementations of the second aspect, the candidate position set is used to label spatial angle information of a beam, where the spatial angle information of the beam is used to determine the spatial angle of the beam. That is, each candidate position in the candidate position set corresponds to at least one parameter of a beam, where the at least one parameter includes a zenith angle and / or an azimuth angle.

[0053] In combination with the second aspect, in certain implementations of the second aspect, the result of the beam measurement includes at least one of the following: the candidate position number corresponding to the beam within the first range, the number of the beam measurement resource corresponding one-to-one to the beam within the first range, and the signal strength of the beam within the first range.

Satellites can also refer to non-ground base stations or non-ground devices.

[0087] The method in the embodiment of the present application can also be applied to scenarios where network devices and terminal devices have perception capabilities.

[0088] With the increase in business demand and the improvement of communication equipment capabilities, in some wireless communication systems, such as the next generation of wireless communication systems (for example, the sixth generation of mobile communication technology), network equipment and terminal devices will have sensing capabilities, including self-transmitting and self-receiving modes and other-transmitting and self-receiving modes. Based on this, network equipment and terminal devices can obtain parameters such as delay, power, angle of departure (AOD), and angle of arrival (AOA) of each path from the network device to the terminal device, and can also obtain information such as the position and orientation of reflectors within the current cell range.

For the sake of convenience of description, the terminal device will be taken as an example for description below.

[0090] It should be understood that in some scenarios, a UE can also be used to act as a base station. For example, a UE can act as a scheduling entity that provides sidelink signals between UEs in scenarios such as V2X, D2D, or P2P.

[0099] First, a communication system applicable to an embodiment of the present application is briefly introduced with reference to FIG1 as follows.

[0100] Figure 1 shows a schematic diagram of a wireless communication system applicable to an embodiment of the present application. As shown in Figure 1, the wireless communication system includes a wireless access network 100. The wireless access network 100 can be a wireless access network in a future communication network, or a traditional (e.g., 5G, 4G, 3G, or 2G) wireless access network. One or more terminal devices (such as terminal device 111, terminal device 112, terminal device 113, and terminal device 114) can be connected to each other or to one or more network devices (such as network device 120) in the wireless access network 100. As shown in Figure 1, there may be reflectors (such as reflector #1 and reflector #2) between the terminal device and the network device. As an example, beam #1 and beam #2 are beams that do not pass through reflectors, and beam #3, beam #4, and beam #5 are beams based on the perception results of effective reflectors.

[0101] FIG1 is only a schematic diagram. The wireless communication system may further include other devices, such as core network devices, wireless relay devices and / or wireless backhaul devices, which are not shown in FIG1 .

[0102] Figure 2 shows a schematic diagram of beam measurement based on sensing results according to an embodiment of the present application. As shown in Figure 2 , based on the sensing results of reflector 230, when network device 210 and terminal device 220 perform beam measurement, measurements are performed on beams 241, 242, and 243 that pass through reflector 230. Measurements are not performed on beams 240 and 244 that do not pass through reflector 230.

[0103] To facilitate understanding of the embodiments of the present application, a brief explanation of the terms involved in the present application is given.

[0104] 1. Beam: It can be understood as a spatial filter or spatial parameters. The beam used to send signals can be called a transmission beam (Tx beam), which can be a spatial domain transmit filter or spatial transmit parameters (spatial Tx parameters), or a spatial transmission angle (such as azimuth, zenith angle) or a spatial transmission angle range (such as azimuth center angle and offset, azimuth uncertainty, azimuth protection range, zenith center angle and offset, zenith angle uncertainty, zenith angle protection range), etc.; the beam used to receive signals can be called a reception beam (Rx beam), which can be a spatial domain receive filter or spatial receive parameters (spatial Rx parameters), or a spatial reception angle (such as azimuth, zenith angle) or a spatial reception angle range (such as azimuth center angle and offset, azimuth uncertainty, azimuth protection range, zenith center angle and offset, zenith angle uncertainty, zenith angle protection range), etc.

[0105] The technology for forming the beam may be a beamforming technology or other technology. For example, the beamforming technology may specifically be a digital beamforming technology, an analog beamforming technology, or a hybrid digital / analog beamforming technology. A transmit beam may refer to the distribution of signal strength in different directions in space after the signal is transmitted by the antenna, and a receive beam may refer to the distribution of signal strength in different directions in space of the wireless signal received from the antenna. The beamforming technology of the present application may be implemented based on a power amplifier made of new materials, or based on a new antenna architecture, such as a new hybrid phased array and lens antenna technology.

[0106] In the 5G-NR protocol, a beam can be a spatial filter. However, it should be understood that this application does not exclude the possibility of defining other terms in future protocols to express the same or similar meanings.

[0107] 2. Antenna panel: Also referred to as a panel. Each antenna panel can be configured with one or more receive beams and one or more transmit beams. Therefore, an antenna panel can also be considered a beam group. Communication devices, such as terminal devices or network equipment, can receive signals using the receive beams on the antenna panel and transmit signals using the transmit beams on the antenna panel.

[0108] In an embodiment of the present application, for a terminal device, panels can be distinguished by uplink reference signal resources. The uplink reference signal can be a sounding reference signal (SRS). By way of example and not limitation, one antenna panel can correspond to one SRS resource set identifier (ID). That is, one SRS resource set ID can be used to indicate one terminal device panel.

[0109] For network devices, the network devices may be distinguished by a panel ID, for example, a transmission configuration indicator (TCI) may be used to indicate the panel ID.

[0110] 3. Quasi-co-location (QCL): Also known as quasi-colocation. Antenna ports with a QCL relationship will experience the same or similar channel parameters, or the channel parameters experienced by one antenna port can be used to determine the channel parameters experienced by another antenna port with a QCL relationship, or, alternatively, the difference in channel parameters experienced by the two antenna ports is less than a certain threshold.

[0111] An antenna port (also referred to as a port) refers to a transmitting antenna identified by a receiving device, or a spatially distinguishable transmitting antenna. Each virtual antenna can be configured with an antenna port. Each virtual antenna can be a weighted combination of multiple physical antennas, and each antenna port can correspond to a reference signal port.

[0112] The channel parameters may include one or more of the following: delay spread, Doppler spread, Doppler shift, average delay, average gain, and spatial reception parameters. The spatial reception parameters may include, for example, angle of arrival, average AOA, AOA spread, angle of departure, average angle of departure AOD, AOD spread, receive antenna spatial correlation parameter, transmit antenna spatial correlation parameter, transmit beam, receive beam, and resource identifier.

[0113] The above-mentioned angles can be decomposition values ​​of different dimensions, or a combination of decomposition values ​​of different dimensions. The above-mentioned antenna ports are antenna ports with different antenna port numbers, and / or antenna ports with the same antenna port number that send or receive information at different times and / or frequencies and / or code domain resources, and / or antenna ports with different antenna port numbers that send or receive information at different times and / or frequencies and / or code domain resources. The above-mentioned resource identifier can be used to indicate an identifier on a resource. The resource identifier may, for example, include a CSI-RS resource identifier, an SRS resource identifier, a resource identifier of a synchronization signal / synchronization signal block, a resource identifier of a preamble sequence transmitted on a physical random access channel (PRACH), or a demodulation reference signal (DMRS) resource identifier.

[0114] In the 5G-NR protocol, QCL relationships can be divided into the following four types based on different parameters:

[0115] Type A: Doppler shift, Doppler spread, average delay, delay spread;

[0116] Type B: Doppler shift, Doppler spread;

[0117] Type C: Doppler shift, average delay;

[0118] Type D: space receiving parameters.

[0119] The QCLs described in the embodiments of this application are Type D QCLs. Unless otherwise specified, the QCLs herein are understood to be Type D QCLs, i.e., QCLs defined based on spatial reception parameters. However, it should be understood that this application does not preclude the possibility of defining other terms in future protocols to express the same or similar meanings.

[0120] When the QCL relationship refers to a QCL relationship of type D: the QCL relationship between a port of a downlink signal and a port of a downlink signal, or between a port of an uplink signal and a port of an uplink signal, can be that the two signals have the same AOA or AOD, which is used to indicate that they have the same receive beam or transmit beam. For another example, for the QCL relationship between a downlink signal and an uplink signal, or between the ports of an uplink signal and a downlink signal, the AOA and AOD of the two signals can have a corresponding relationship, or the AOD and AOA of the two signals can have a corresponding relationship, that is, beam reciprocity can be used to determine the uplink transmit beam based on the downlink receive beam, or to determine the downlink receive beam based on the uplink transmit beam.

[0121] The signal transmitted on the port with a spatial QCL relationship can also have a corresponding beam, and the corresponding beam includes at least one of the following: the same or similar receiving beam, the same or similar transmitting beam, a transmitting beam corresponding to the receiving beam (corresponding to a scenario with beam reciprocity), and a receiving beam corresponding to the transmitting beam (corresponding to a scenario with beam reciprocity).

[0122] Signals transmitted on ports with a spatial QCL relationship can also be understood as signals received or transmitted using the same spatial filter. The spatial filter can be at least one of the following: precoding, antenna port weight, antenna port phase shift, and antenna port amplitude gain.

[0123] The signal transmitted on the port with a spatial QCL relationship can also be understood as having a corresponding beam pair link (BPL), and the corresponding BPL includes at least one of the following: the same downlink BPL, the same uplink BPL, the uplink BPL corresponding to the downlink BPL, and the downlink BPL corresponding to the uplink BPL.

[0124] Therefore, the spatial reception parameter (ie, QCL of type D) may be understood as a parameter for indicating directional information of a reception and / or transmission beam.

[0125] 4. Beam pair link (BPL): The pairing relationship between a transmit beam and a receive beam, also known as the pairing relationship between a spatial transmit filter and a spatial receive filter. Transmitting signals between transmit and receive beams that have a beam pairing relationship can achieve greater beamforming gain.

[0126] In one possible implementation, the transmitting end may send a reference signal by beam scanning, and the receiving end may also receive the reference signal by beam scanning. Specifically, the transmitting end may form beams with different directivities in space by beamforming, and may poll on multiple beams with different directivities to transmit the reference signal through beams with different directivities, so that the power of the reference signal in the direction pointed by the transmitting beam can be maximized. The receiving end may also form receiving beams corresponding to different spatial directions and directivities by beamforming, and may poll on multiple beams with different directivities to receive the reference signal through beams with different directivities, so that the power of the reference signal received by the receiving end can be maximized in the direction pointed by the receiving beam.

[0127] By traversing each transmit beam and receive beam, the receiver can perform channel measurements based on the received reference signal and report the measurement results to the transmitter. For example, the receiver can report reference signal resources with higher reference signal received power (RSRP) to the transmitter, such as reporting the identifier of the reference signal resource, so that the transmitter can use the beam pairing relationship with better channel quality to transmit and receive signals when transmitting data or signaling.

[0128] 5. Reference Signal (RS) and Reference Signal Resource (RS Resource): Reference signals can be used for channel measurement, channel estimation, or beam quality monitoring. Reference signal resources can be used to configure reference signal transmission properties, such as time-frequency resource location, port mapping, power factor, and scrambling code. Transmitting devices can send reference signals based on reference signal resources, and receiving devices can receive reference signals based on reference signal resources.

[0129] The reference signals involved in the embodiments of the present application may include, for example, a channel state information reference signal (CSI-RS), a synchronization signal block (SSB), and a sounding reference signal. Correspondingly, reference signal resources may include CSI-RS resources, SSB resources, and SRS resources.

[0130] To distinguish different reference signal resources, each reference signal resource may correspond to a reference signal resource identifier, such as a CSI-RS resource indicator (CRI), an SSB resource indicator (SSBRI), or an SRS resource index (SRI).

[0131] It should be noted that the above-mentioned SSB resources can also be understood as synchronization signal / physical broadcast channel block (SS / PBCH block) resources. In the embodiments of the present application, for the convenience of distinction and explanation, unless otherwise specified, SSB resources and SS / PBCH block resources can have the same meaning, and SSB resources and SS / PBCH block resources can have the same meaning. In addition, in some cases, SSB can also refer to SSB resources. Therefore, the SSB resource identifier can sometimes also be referred to as the SSB identifier (SSB index).

[0132] It should be understood that the reference signals and corresponding reference signal resources listed above are only exemplary and should not constitute any limitation to this application. This application does not exclude the possibility of defining other reference signals in future protocols to achieve the same or similar functions.

[0133] In the configuration signaling of the reference signal resource, different time domain behaviors can be indicated by different time domain behavior parameters. As an example and not a limitation, the time domain behaviors may include periodic, semi-persistent (SP), and aperiodic (AP).

[0134] For example, based on different time domain behaviors, CSI-RS may include periodic CSI-RS, aperiodic CSI-RS, and semi-persistent CSI-RS. Based on different time domain behaviors, SRS may also include periodic SRS, aperiodic SRS, and semi-persistent SRS.

[0135] 6. Transport Configuration Indicator (TCI) Status: This indicates the QCL relationship between two reference signals. The TCI status allows the terminal device to determine the receive beam for a downlink signal or downlink channel.

[0136] Each TCI state may include a reference signal resource identifier. The reference signal resource identifier may be, for example, at least one of the following: a non-zero power (NZP) channel state information reference signal (CSI-RS) resource identifier (NZP-CSI-RS-ResourceId) or an SSB index (SSB-Index).

[0137] It should be noted that the reference signal resource identifier in each TCI state indicates the reference signal resource used in the beam training process. Since during the beam training process, the network device can send reference signals through different transmit beams based on different reference signal resources, the reference signals sent through different transmit beams can be associated with different reference signal resources; the terminal device can receive reference signals through different receive beams based on different reference signal resources, so the reference signals received through different receive beams can also be associated with different reference signal resources. Therefore, during the beam training process, the terminal device can maintain the corresponding relationship between the reference signal resource identifier and the receive beam, and the network device can maintain the corresponding relationship between the reference signal resource identifier and the transmit beam. Through the reference signal resource identifier, a pairing relationship between the receive beam and the transmit beam can be established.

[0138] In the subsequent communication process, the terminal device can determine the receiving beam based on the TCI state indicated by the network device, and the network device can determine the transmitting beam based on the same TCI state.

[0139] It should be understood that the information included in the TCI status listed here is only an example and should not constitute any limitation to this application. For example, the TCI status may also include the serving cell index (ServeCellIndex), the bandwidth part (BWP) identifier (ID), etc. Since the embodiments of this application do not involve serving cells and BWP, they are not described in detail.

[0140] 7. Spatial relation (SR): Also known as uplink TCI (UL TCI), similar to the TCI described above, spatial relation can be used by terminal devices to determine the transmit beam of uplink signals or uplink channels.

[0141] Each spatial relationship may include a reference signal resource identifier, where the reference signal resource identifier may be, for example, any one of the following: an SSB index (SSB-Index), a non-zero power CSI-RS reference signal resource identifier (NZP-CSI-RS-ResourceId), and an SRS resource identifier (SRS-ResourceId).

[0142] The reference signal resource identifier (RSRI) refers to the reference signal resource used during beam training. A spatial relationship is used to determine a transmit beam. The terminal device can maintain the correspondence between the RSI and the transmit beam during beam training, and the network device can maintain the correspondence between the RSI and the receive beam during beam training. The RSI can be used to establish a pairing between the transmit and receive beams.

[0143] In the subsequent communication process, the terminal device can determine the transmission beam based on the spatial relationship indicated by the network device, and the network device can determine the receiving beam based on the same spatial relationship.

[0144] In addition, each spatial relationship may also include power control information. The power control information may include, for example, at least one of the following: expected receive power, a path loss reference signal, and a path loss compensation parameter. The terminal device may determine the transmit power to use for transmitting uplink signals based on the power control information.

[0145] It should be understood that the information included in the spatial relationships listed here is only an example and should not constitute any limitation to this application. For example, the spatial relationship may also include the serving cell index (ServeCellIndex), the bandwidth part (band width part, BWP) identifier (ID), etc. Since the embodiments of this application do not involve serving cells and BWP, they are not described in detail here.

[0146] The terminal device and the network device can achieve beam alignment between the terminal device and the network device through information exchange. The terminal device can perform beam measurement based on the reference signal sent by the network device (for example, SSB or channel state information reference signal (CSI-RS)), and report the reference signal number and beam quality information corresponding to one or more beams (for example, reference signal receive power (RSRP) or signal to interference plus noise ratio (SINR)). The network device can indicate to the terminal device the reference signal resource number corresponding to the service beam and / or the reference signal resource number corresponding to the service beam and the QCL relationship of the reference signal resource number corresponding to the measurement beam, for subsequent data transmission. In order to ensure the beam alignment state between the network device and the terminal device, the information exchange between the above-mentioned terminal device and the network device is usually continuous.

[0147] Furthermore, current wireless communication systems are incorporating higher-frequency spectrum resources, such as millimeter-wave and terahertz bands, to meet growing communication demands. Typically, wireless signals experience greater path loss at higher frequencies, which reduces their range. In millimeter-wave and terahertz bands, beamforming technology can be used to focus signal energy within a specific angle range, thereby increasing wireless signal coverage.

[0148] Before introducing the solution of this application, the following points are explained.

[0149] (1) In this application, “indication” may include direct indication, indirect indication, explicit indication, and implicit indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0150] In this application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each information agreed in advance (for example, stipulated by the protocol), thereby reducing the indication overhead to a certain extent. In addition, the information to be indicated can be sent together as a whole, or it can be divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different.

[0151] (2) In this application, "sending" and "receiving" indicate the direction of signal transmission. For example, "sending information to XX" can be understood as the destination of the information being XX, which can include direct sending through the air interface, and also include indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as the source of the information being YY, which can include direct receiving from YY through the air interface, and also include indirect receiving from YY through the air interface from other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, sending and receiving can be carried out between devices, for example, between a network device and a terminal device, or can be carried out within a device, for example, sending or receiving between components, modules, chips, software modules or hardware modules within the device through a bus, a line or an interface.

[0152] (3) In the various embodiments of this application, unless otherwise specified or there is a logical conflict, the terms and / or descriptions between different embodiments are consistent and can be referenced by each other. The technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.

[0153] (4) In this application, the terms "first" and "second" are used for convenience of description only and are not intended to limit the scope of the embodiments of this application. They are not used to describe the order or precedence of features. It should be understood that the terms described in this manner may be interchangeable, where appropriate, to describe solutions other than the embodiments of this application.

[0154] The method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings. The embodiment provided by the present application can be applied to the communication system shown in FIG1 above without limitation.

[0155] In the following embodiments, terminal devices and network devices are used as examples for illustrative description.

[0156] The terminal device can be replaced by a component of the terminal device (such as a chip or circuit), or a network device, or a component of the network device (such as a chip or circuit). The network device can be replaced by a component of the network device (such as a chip or circuit), or a terminal device, or a component of the terminal device (such as a chip or circuit).

[0157] Figure 3 shows a schematic diagram of a communication method provided by an embodiment of the present application. The method 300 shown in Figure 3 may include the following steps.

[0158] Optionally, method 300 includes step S301.

[0159] S301, the network device sends indication information #A (i.e., an example of second indication information), and accordingly, the terminal device receives indication information #A.

[0160] As an example, the indication information #A is carried in any of the following: radio resource control (RRC) signaling, system message (eg, master information block (MIB) or system information block (SIB)).

[0161] The indication information #A indicates a candidate position set, which includes multiple candidate positions. Each candidate position corresponds to a plurality of beams. That is, each candidate position corresponds to one beam, and different candidate positions correspond to different beams, such as beams at different angles.

[0162] As an example, the candidate position set may be a candidate angle set.

[0163] The candidate location set may also be referred to as a location set, or as a spatial grid, or as a grid, or as a network, or as a spatial grid, and there is no limitation on the naming. Below, it is uniformly described as a spatial grid, and the candidate locations in the candidate location set are referred to as grid points.

[0164] Optionally, the spatial grid can be in the form of coordinates. For example, the spatial grid is a two-dimensional coordinate, and the horizontal coordinate and vertical coordinate of the spatial grid can be the beam angle information of the beam. The beam angle information can also be called beam angle range information or angle range information, etc. For example, the horizontal coordinate of the spatial grid is a first parameter and the vertical coordinate is a second parameter, wherein the first parameter is the zenith angle of the beam and the second parameter is the azimuth angle; or, the first parameter is the azimuth angle and the second parameter is the zenith angle. The zenith angle can represent the angle between the straight line direction from the network device to the terminal device and the direction perpendicular to the terminal device; the azimuth angle can represent the horizontal angle between the straight line direction from the terminal device to the network device and the reference direction.

[0165] The embodiments of the present application are mainly illustrated using the first parameter and the second parameter as examples, which are not limited thereto. For example, a greater or lesser number of parameters may be indicated in the spatial grid.

[0166] The network side may configure and / or indicate the spatial grid, or the spatial grid may be predefined by the protocol, which is not limited in the embodiments of the present application.

[0167] In one possible implementation, the spatial grid is uniform. For example, indication information #A indicates a uniform spatial grid, meaning that the spatial grid indicated by indication information #A is a uniform spatial grid. In a uniform spatial grid, the intervals between adjacent grid points are the same, or the grid points in the uniform spatial grid are evenly distributed.

[0168] It should be understood that the intervals between every two adjacent grid points in the uniform spatial grid are the same, that is, the intervals between the values ​​of two adjacent first parameters in the spatial grid are the same, and the intervals between the values ​​of two adjacent second parameters in the spatial grid are the same.

[0169] In another possible implementation, the spatial grid is non-uniform. For example, indication information #A indicates a non-uniform spatial grid, meaning that the spatial grid indicated by indication information #A is a non-uniform spatial grid. In the non-uniform spatial grid, the intervals between adjacent grid points are different, or the grid points in the non-uniform spatial grid are non-uniformly distributed.

[0170] It should be understood that the intervals between each two adjacent grid points in the non-uniform spatial grid are different, that is, the intervals between the values ​​of two adjacent first parameters in the spatial grid are not exactly the same, and / or the intervals between the values ​​of two adjacent second parameters in the spatial grid are not exactly the same.

[0171] Figure 4 shows a schematic diagram of a spatial grid provided by an embodiment of the present application. As shown in Figure 4 , it is assumed that the horizontal coordinate is the azimuth angle and the vertical coordinate is the zenith angle.

[0172] As shown in Figure 4(a), the spatial grid is uniform, meaning that the intervals between adjacent azimuth angles are the same, and the intervals between adjacent zenith angles are also the same. Assuming the azimuth angle range is [-40, 40], with a step size of 5, the horizontal axis includes 17 values; assuming the zenith angle range is [100, 128], with a step size of 4, the vertical axis includes 8 values. Based on the set values ​​of the azimuth and zenith angles, grid points within the uniform spatial grid can be formed. At least one of the zenith angle and azimuth angle of the beam corresponding to different grid points may be different.

[0173] It should be understood that the uniform spatial grid shown in (a) in Figure 4 is only an example. The specific selection of horizontal or vertical coordinate parameters, the azimuth or zenith angle value range and the step size can be configured by the network device according to the actual beam coverage range, coverage distance or antenna scale. The embodiments of the present application do not impose any restrictions on this.

[0174] As shown in (b) of FIG4 , the spatial grid is a non-uniform spatial grid, that is, the intervals between two adjacent azimuth angles are not completely the same, and the intervals between two adjacent zenith angles are not completely the same.

[0175] In one possible implementation, a non-uniform spatial grid is used in scenarios where network devices use narrow beams to cover cell edges and wide beams to cover cell centers. Specifically, the non-uniform spatial grid is used to indicate at least one parameter of different beams, where different beams refer to beams of varying widths.

[0176] It should be understood that the non-uniform spatial grid shown in (b) of Figure 4 is only an example. The specific parameter selection of the horizontal or vertical coordinate can be configured by the network device according to the actual application scenario, actual beam coverage range, coverage distance or antenna scale. The embodiments of the present application do not limit this.

[0177] S302, the network device sends indication information #B (an example of first indication information), and accordingly, the terminal device receives indication information #B.

[0178] The indication information #B indicates the beam range to be measured (or simply referred to as the beam range, which is an example of the first range), so that the terminal device determines the same beam range as the network side according to the indication information #B. The beam range includes one or more beams.

[0179] FIG5 shows a schematic diagram of indicating a beam range using a uniform spatial grid as an example according to an embodiment of the present application. The following describes how the indication information #B indicates a beam range in conjunction with FIG5 .

[0180] Method 1: The indication information #B includes relevant parameters indicating the beam range.

[0181] As an example, method 1 can be applied to the case of a uniform spatial grid.

[0182] In one possible implementation, the beam range is circular, and the indication information #B sent by the network device includes relevant parameters of the circle. Therefore, the terminal device determines the circle based on the received indication information #B, and further determines the beam to be measured within the circle.

[0183] Exemplarily, the relevant parameters of the circle include at least one of the following: the position of the center of the circle, and the radius (or offset).

[0184] For example, the indication information #B includes the center position of the circle and the radius, wherein the center position of the circle can be used to determine the center position of the circular beam range, and the radius can be used to determine the size of the circular beam range.

[0185] As shown in Figure 5 (a), the beam range is the range indicated by the dotted line. The network device indicates to the terminal device the center position of the beam range, namely the center angle, namely the center azimuth angle and center zenith angle, as well as the radius. The terminal device then receives the instruction information #B and, based on the instruction information #B, determines the same circular beam range as that on the network device side in the uniform spatial grid. It then determines the beam within this circular beam range, which is the beam to be measured.

[0186] As an example, the number of bits occupied by the center position (such as the center angle) and the radius may satisfy formulas (1)-(3).

[0187] in, To round up.

[0188] In another possible implementation, the beam range is a square, and the indication information #B sent by the network device includes relevant parameters of the square. Therefore, the terminal device determines the square based on the received indication information #B, and further determines the beam to be measured within the square.

[0189] For example, the parameters related to the square include at least one of the following: the position of a corner of the square, the length of the square, the width of the square, the center position of the long side of the square, and the center position of the wide side of the square. For ease of understanding, an exemplary explanation is given in the following manner.

[0190] Method 1

[0191] For example, the indication information #B includes the starting position of the square, the length of the square, and the width of the square, wherein the starting position of the square is used to determine the position of the square beam range, and the length of the square and the width of the square are used to determine the size of the square beam range.

[0192] As shown in Figure 5(b), the beam range is the range indicated by the dotted line. The network device indicates to the terminal device the azimuth and zenith starting angles of the square beam range, as well as the width and length of the square beam range. The terminal device then receives instruction information #B and, based on instruction information #B, determines the same square beam range as that on the network device side within the uniform spatial grid. It then determines the beam within this square beam range, which is the beam to be measured.

[0193] As an example, the number of bits occupied by the position of a corner of a square (such as the azimuth starting angle and the zenith starting angle), the width of the square (such as the width of the square in the azimuth direction) and the length of the square (such as the length of the square in the zenith direction) can satisfy formulas (4)-(7).

[0194] in, To round up.

[0195] Method 2

[0196] For example, the indication information #B includes the center position of the length of the square, the offset of the length of the square, the center position of the width of the square, and the offset of the width of the square.

[0197] When used to express parameters related to a square, the offset refers to half the length of one of the sides of the square.

[0198] As shown in Figure 5 (c), the beam range is the range indicated by the dotted line. The network device indicates to the terminal device the zenith center angle, the offset from the zenith center angle in the direction of the zenith center angle, the azimuth center angle, and the offset from the azimuth center angle in the direction of the azimuth center angle. The terminal device then receives instruction information #B and, based on instruction information #B, determines the same square beam range as that on the network device side within the uniform spatial grid. It then determines the beam within this square beam range, which is the beam to be measured.

[0199] The calculation method of the number of bits occupied by the relevant parameters will not be repeated here.

[0200] Optionally, the shape of the beam range indicated by the indication information #B can also be an ellipse, a parallelogram, or the like. This embodiment of the present application does not limit this. The beam range indicated by the indication information #B only needs to include all beams to be measured.

[0201] Optionally, each grid point within the beam range has a corresponding number. For example, the grid points within the beam range can be numbered first, and then the beam range can be indicated using method 1. The numbering of the grid points can also be called an index. As an example, the grid points can be numbered sequentially from 0 or other numerical values ​​in the order of horizontal coordinates and then vertical coordinates; or the grid points can be numbered sequentially from 0 or other numerical values ​​in the order of vertical coordinates and then horizontal coordinates. This is explained below with reference to Figure 6.

[0202] FIG6 shows an example diagram of numbering grid points within a circular beam range using a uniform spatial grid as an example, provided by an embodiment of the present application.

[0203] In a possible implementation, the network device is configured with a uniform spatial grid as shown in FIG6 , where the range indicated by the dotted line is the beam range, and the grid points within the beam range are numbered.

[0204] Optionally, the grid points within the beam range are numbered along the azimuth angle first and then along the zenith angle. As shown in FIG6 , the grid point number set within the beam range is {0, 1, 2, …, 20}.

[0205] In another possible implementation manner, the terminal device numbers the grid points within the beam range to obtain a set of grid point numbers within the beam range.

[0206] It should be understood that the spatial grid can also indicate fewer or more parameters. For different situations, there are more options for specific numbering methods, which are not limited in the embodiments of the present application.

[0207] Method 2: The indication information #B indicates the number of the grid point within the beam range.

[0208] In a possible implementation, the indication information #B includes the numbers of each grid point within the beam range.

[0209] In another possible implementation, the indication information #B includes at least one of the following:

[0210] (1) The number of the starting grid point within the beam range, and the number of the ending grid point within the beam range; or,

[0211] (2) The number of the starting grid point within the beam range and the number of grid points within the beam range.

[0212] Through at least one of the above items, the numbers of the grid points within the beam range can be obtained.

[0213] As an example, method 2 can be applied to both uniform and non-uniform spatial grids.

[0214] FIG7 shows a schematic diagram of indicating a beam range using a uniform spatial grid as an example provided by an embodiment of the present application. Method 2 is described below in conjunction with FIG7 .

[0215] Assume that the grid points are numbered first along the azimuth direction and then along the zenith angle direction.

[0216] In one possible embodiment, after the network device determines the beam range in the spatial grid in step S302, it directly sends the numbers of the grid points in the beam range to the terminal device, that is, the indication information #B includes the numbers of all grid points in the beam range, that is, the indication information #B includes {21,22,23,37,38,39,40,41,54,55,56,57,58,71,72,73,74,75,89,90,91}.

[0217] In another possible implementation, the indication information #B includes the number 21 of the starting grid point within the beam range and the number 91 of the ending grid point; or, the indication information #B includes the number 21 of the starting grid point within the beam range and the number of grid points within the beam range 21.

[0218] S303, the network device sends a reference signal, and correspondingly, the terminal device receives the reference signal.

[0219] The reference signal may also be called a pilot or a pilot sequence, and may be used for channel estimation in a communication system.

[0220] Specifically, after determining the beam range, the network device sends multiple reference signals based on the beam within the beam range; accordingly, the terminal device receives the reference signals sent by the network device and performs beam measurement.

[0221] Based on this solution, the network device sends a reference signal for the beam to be measured within the beam range, reducing communication overhead. The terminal device receives the reference signal sent by the network device and performs beam measurement, improving the efficiency of beam measurement.

[0222] S304: The terminal device determines beam measurement resources.

[0223] Specifically, the terminal device determines the beam measurement resource based on the received reference signal.

[0224] Optionally, the beam measurement resources include time-frequency resources.

[0225] The grid points within the beam range should correspond one-to-one to the beam measurement resources, that is, the number of grid points within the beam range is the number of beam measurement resources, denoted as N, where N is an integer.

[0226] In one possible implementation, the numbering method of the beam measurement resources can refer to the numbering method of the grid points within the beam range as shown in Figure 6, so that the grid point numbers within the beam range correspond one-to-one to the beam measurement resource numbers.

[0227] It should be understood that numbering the beam measurement resources can also be understood as a beam measurement resource configuration index, or adding indication information to the beam measurement resources. The embodiments of the present application do not limit the specific method of marking the beam measurement resources.

[0228] S305, the terminal device sends the beam measurement result, and correspondingly, the network device receives the beam measurement result.

[0229] Specifically, the terminal device reports the determined beam measurement resources as the result of the beam measurement.

[0230] In addition, the results of the beam measurement also include at least one of the following: the grid point number corresponding to the beam within the beam range determined by the network device or the terminal device, the number of the beam measurement resource determined by the terminal device that corresponds one-to-one to the beam within the beam range, and the signal strength of the beam in the corresponding direction obtained after the terminal device performs beam measurement on the beam within the beam range.

[0231] Optionally, the result of the beam measurement includes determined time-frequency resources.

[0232] Exemplarily, the i-th time-frequency resource is located at the i+offset-th OFDM symbol, where i=0, ..., N-1, where N is the number of beam measurement resources and offset is the offset in the time domain. As an example, offset can be 0.

[0233] Optionally, the result of the beam measurement includes a bit width, where the bit width represents the number of bits occupied by the transmission beam measurement resources.

[0234] For example, the bit width satisfies formula (8):

[0235] in, To round up, N is the number of beam measurement resources.

[0236] For ease of understanding, several possible application scenarios of the application method 300 are introduced below.

[0237] Figure 8 is a schematic diagram of configuring beam measurement resources based on a uniform spatial grid and a circular beam range in a perception scenario provided by an embodiment of the present application.

[0238] As shown in (a) of Figure 8 , the network device 810 configures or predefines a uniform spatial grid, and the uniform spatial grid can indicate beam angle information. The network device 810 can send indication information #A to the terminal device 820 to indicate the uniform spatial grid.

[0239] In a possible implementation, as shown in (a) of FIG8 , based on the fact that the reflecting surface of the effective reflector is circular, the network device 810 and the terminal device 820 measure the beam based on the sensing result.

[0240] The network device 810 determines a beam range in the uniform spatial grid according to the beam to be measured, such as the range indicated by the dotted line in the uniform spatial grid in FIG8(a).

[0241] Network device 810 sends indication information #B, which includes the center position (i.e., the center azimuth angle and the center zenith angle) and the radius. The beam range determined based on indication information #B includes all beams to be measured. The specific method for determining the relevant parameters is not further described here.

[0242] The network device 810 transmits a reference signal using a beam within the beam range.

[0243] The terminal device 820 can determine the same beam range as the network side based on the indication information #A and the indication information #B, and perform beam measurement based on the reference signal sent by the network device 810.

[0244] Network device 810 and terminal device 820 number the grid points within the beam range using the same numbering method (e.g., first the horizontal coordinate and then the vertical coordinate, or first the vertical coordinate and then the horizontal coordinate). The numbering order is first along the azimuth direction and then along the zenith angle direction. The output grid point number set is {0, 1, 2, 3, 4, 5, ..., 20}, that is, the output grid point set includes N grid points, where N is an integer, and in this case, N is 21. The numbering method can be instructed by network device 810 to terminal device 820 or predefined.

[0245] (b) in FIG8 shows a schematic diagram of the terminal device 820 determining the beam measurement time-frequency resources, and numbering the beam measurement time-frequency resources. The numbering method can refer to the method of numbering the grid points within the beam range shown in FIG6 , which will not be repeated here.

[0246] The grid point numbers within the beam range correspond one-to-one to the beam measurement time-frequency resources. That is, the number of grid points N within the beam range is the number of beam measurement time-frequency resources. For example, the 21 grid points within the beam range shown in Figure 8(a) correspond to the 21 beam measurement time-frequency resources shown in Figure 8(b).

[0247] The terminal device 820 reports the beam measurement result.

[0248] Figure 9 is a schematic diagram of configuring beam measurement resources based on a uniform spatial grid and a square beam range in a perception scenario provided by an embodiment of the present application.

[0249] As shown in (a) of Figure 9 , the network device 910 configures or predefines a uniform spatial grid, and the uniform spatial grid can indicate beam angle information. The network device 910 can send indication information #A to the terminal device 920 to indicate the uniform spatial grid.

[0250] In a possible implementation, as shown in (a) of FIG9 , based on the fact that the reflecting surface of the effective reflector is square, the network device 910 and the terminal device 920 measure the beam based on the sensing result.

[0251] The network device 910 determines a beam range in the uniform spatial grid according to the beam to be measured, such as the range indicated by the dotted line in the uniform spatial grid in FIG9 (a).

[0252] Network device 910 sends indication information #B. Indication information #B includes the position of a corner of the square (e.g., the azimuth starting angle and the zenith starting angle), the width of the square (the width of the square in the azimuth direction), and the length of the square (the length of the square in the zenith direction). The beam range determined according to indication information #B includes all beams to be measured. The specific method for determining the relevant parameters is not further described here.

[0253] The network device 910 transmits a reference signal using a beam within the beam range.

[0254] The terminal device 920 can determine the same beam range as the network side based on the indication information #A and the indication information #B, and perform beam measurement based on the reference signal sent by the network device 910.

[0255] Network device 910 and terminal device 920 number the grid points within the beam range using the same numbering method (e.g., first the horizontal coordinate and then the vertical coordinate, or first the vertical coordinate and then the horizontal coordinate). The numbering order is first along the azimuth direction and then along the zenith angle direction. The output grid point number set is {0, 1, 2, 3, 4, 5, ..., 14}, that is, the output grid point set includes N grid points, where N is an integer, and in this case, N is 15. The numbering method can be instructed by network device 910 to terminal device 920 or predefined.

[0256] (b) in FIG9 shows a schematic diagram of the terminal device 920 determining the beam measurement time-frequency resources, and numbering the beam measurement time-frequency resources. The numbering method can refer to the method of numbering the grid points within the beam range shown in FIG6 , which will not be repeated here.

[0257] It should be understood that the grid point numbers within the beam range correspond one-to-one to the beam measurement time-frequency resources, that is, the number of grid points N within the beam range is the number of beam measurement time-frequency resources. For example, the 15 grid points within the beam range shown in Figure 9 (a) correspond to the 15 beam measurement time-frequency resources shown in Figure 9 (b).

[0258] The terminal device 920 reports the beam measurement result.

[0259] Figure 10 is a schematic diagram of configuring beam measurement resources based on a uniform spatial grid in a perception scenario provided by an embodiment of the present application.

[0260] In one possible implementation, as shown in FIG10( a ), network device 1010 configures or predefines a uniform spatial grid, which can indicate beam angle information. The network device numbers all grid points in the uniform spatial grid and then sends indication information #A to terminal device 1020 to indicate the uniform spatial grid.

[0261] In a possible implementation, as shown in (a) of FIG8 , based on the fact that the reflecting surface of the effective reflector is circular, the network device 1010 and the terminal device 1020 measure the beam based on the sensing result.

[0262] The network device 1010 determines a beam range in the uniform spatial grid according to the beam to be measured, such as the range indicated by the dotted line in the uniform spatial grid in FIG10( a ).

[0263] The network device 1010 sends an instruction message #B, which includes:

[0264] {21,22,23,37,38,39,40,41,54,55,56,57,58,71,72,73,74,75,89,90,91}.

[0265] The indication information #B includes the numbers of all beams to be measured, that is, the indication information #B includes a set of N grid point numbers, where N is an integer, and here N is 21.

[0266] The network device 1010 transmits a reference signal using a beam within the beam range.

[0267] The terminal device 1020 can determine the same beam range as the network side based on the indication information #A and the indication information #B, and perform beam measurement based on the reference signal sent by the network device 1010.

[0268] (b) in Figure 10 shows a schematic diagram of the terminal device 1020 determining the beam measurement time-frequency resources, and numbering the beam measurement time-frequency resources. The numbering method can refer to the method of numbering the grid points within the beam range shown in Figure 6, which will not be repeated here.

[0269] It should be understood that the grid point numbers within the beam range correspond one-to-one to the beam measurement time-frequency resources, that is, the number of grid points N within the beam range is the number of beam measurement time-frequency resources. For example, the 21 grid points within the beam range shown in Figure 10 (a) correspond to the 21 beam measurement time-frequency resources shown in Figure 10 (b).

[0270] The terminal device 1020 reports the beam measurement result.

[0271] Figure 11 is a schematic diagram of configuring beam measurement resources based on a non-uniform spatial grid and a circular beam range in a perception scenario provided by an embodiment of the present application.

[0272] In a possible implementation, the network device 1110 uses a narrow beam to cover the cell edge and a wide beam to cover the cell center.

[0273] Based on this beam arrangement, as shown in FIG11( a ), network device 1110 configures or predefines a non-uniform spatial grid, which may indicate beam angle information. Network device 1110 may send indication information #A to terminal device 1120 to indicate the non-uniform spatial grid.

[0274] In one possible implementation, as shown in (a) in FIG11 , the network device 1110 pre-configures the first and second parameters (i.e., the zenith angle and the azimuth angle) of all beams. Based on the circular reflecting surface of the effective reflector, the network device 1110 and the terminal device 1120 measure the beams based on the perception results, and do not measure the beams that do not pass through the reflector.

[0275] The network device 1110 determines the beam range in the spatial grid according to the beam to be measured, as shown in the range indicated by the dotted line in the non-uniform spatial grid in (a) of Figure 11. It can be seen that the beam range is circular, where the grid points outside the beam range correspond to beams that do not pass through reflectors.

[0276] Network device 1110 sends indication information #B, which includes the center position (i.e., the center azimuth angle and the center zenith angle) and the radius. The beam range determined based on indication information #B includes all beams to be measured. The specific method for determining the relevant parameters is not further described here.

[0277] The network device 1110 transmits a reference signal using a beam within the beam range.

[0278] The terminal device 1120 can determine the same beam range as the network side based on the indication information #A and the indication information #B, and perform beam measurement based on the reference signal sent by the network device 1110.

[0279] Network device 1110 and terminal device 1120 number the grid points within the beam range using the same numbering method (e.g., first the horizontal coordinate and then the vertical coordinate, or first the vertical coordinate and then the horizontal coordinate). The numbering order is first along the azimuth direction and then along the zenith angle direction. The output grid point number set is {0, 1, 2, 3}, that is, the output grid point set includes N grid points, where N is an integer, and N is 4 in this case. The numbering method can be instructed by network device 1110 to terminal device 1120 or predefined.

[0280] (b) in Figure 11 shows a schematic diagram of determining the beam measurement time-frequency resources based on the grid points within the beam range. The beam measurement time-frequency resources are numbered. The numbering method can refer to the method of numbering the grid points within the beam range shown in Figure 6, which will not be repeated here.

[0281] The grid point numbers within the beam range correspond one-to-one to the beam measurement time-frequency resources. That is, the number of grid points N within the beam range is the number of beam measurement time-frequency resources. For example, the four grid points within the beam range shown in Figure 11(a) correspond to the four beam measurement time-frequency resources shown in Figure 11(b).

[0282] The terminal device 1120 reports the beam measurement result.

[0283] FIG12 is a schematic diagram of configuring beam measurement resources based on a spatial position grid and a circular beam range, provided in an embodiment of the present application.

[0284] As shown in (a) of FIG. 12 , the network device 1210 configures or predefines a spatial location grid, and the spatial location grid may indicate ground locations covered by the beam.

[0285] Optionally, based on the ground position assumption, the horizontal coordinate of the spatial position grid is the X-axis, the vertical coordinate is the Y-axis, and the grid points in the spatial position grid are evenly distributed.

[0286] It should be understood that the uniform spatial position grid shown in (a) of Figure 12 is only an example. The specific setting of the horizontal or vertical coordinate, the value range of the X-axis and the Y-axis, and the step size can be configured by the network device 1210 according to the actual beam coverage range, coverage distance or antenna scale. The embodiment of the present application does not limit this.

[0287] The network device 1210 sends indication information #A to the terminal device 1220 to indicate the uniform spatial position grid.

[0288] In one possible implementation, as shown in (a) in FIG12 , the network device 1210 pre-configures the ground position information of all beams. Based on the fact that the reflecting surface of the effective reflector is circular, the network device 1210 and the terminal device 1220 measure the beams based on the perception results, and do not measure the beams that do not pass through the reflector.

[0289] The network device 1210 determines the beam range in the uniform spatial position grid based on the beam to be measured, as shown in the range indicated by the dotted line in the uniform spatial position grid in (a) of Figure 12. It can be seen that the beam range is circular, where the grid points outside the beam range correspond to beams that do not pass through reflectors.

[0290] Network device 1210 sends indication information #B, which includes the center position (i.e., the center X-axis position and the center Y-axis position) and the radius. The beam range determined based on indication information #B includes all beams to be measured. The specific method for determining the relevant parameters is not further described here.

[0291] The network device 1210 transmits a reference signal using a beam within the beam range.

[0292] The terminal device 1220 can determine the same beam range as the network side based on the indication information #A and the indication information #B, and perform beam measurement based on the reference signal sent by the network device 1210.

[0293] Network device 1210 and terminal device 1220 number the grid points within the beam range using the same numbering method (e.g., first the horizontal coordinate and then the vertical coordinate, or first the vertical coordinate and then the horizontal coordinate). The numbering order is first along the X-axis and then along the Y-axis. The output grid point number set is {0, 1, 2, 3, 4, 5, ..., 9}, that is, the output grid point set includes N grid points, where N is an integer, and in this case, N is 10. The numbering method can be instructed by network device 1210 to terminal device 1220 or predefined.

[0294] (b) in Figure 12 shows a schematic diagram of determining the beam measurement time-frequency resources based on the grid points within the beam range. The beam measurement time-frequency resources are numbered. The numbering method can refer to the method of numbering the grid points within the beam range shown in Figure 6, which will not be repeated here.

[0295] The grid point numbers within the beam range correspond one-to-one to the beam measurement time-frequency resources. That is, the number of grid points N within the beam range is the number of beam measurement time-frequency resources. For example, the 10 grid points within the beam range shown in Figure 12(a) correspond to the 10 beam measurement time-frequency resources shown in Figure 12(b).

[0296] In another possible implementation, the network device configures a non-uniform spatial position grid for the terminal device, that is, the horizontal coordinate is set as the X-axis and the vertical coordinate is set as the Y-axis based on the ground position, and the grid points in the spatial position grid are non-uniformly distributed.

[0297] The terminal device 1220 reports the beam measurement result.
