Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a beam measurement method and a communication device. Background Art

[0002] The network device and the terminal device need to perform beam alignment for subsequent data transmission. However, in order to maintain the beam alignment state between the network device and the terminal device, the terminal device needs to measure the beam based on the reference signal sent by the network device and report the measurement result to the network device, and the network device indicates the serving beam. In addition, to ensure support for mobility, this process usually needs to be continuously performed. This will bring extremely high indication overhead. Summary of the Invention

[0003] This application provides a beam measurement method and a communication device, so as to reduce the indication overhead of real-time beam measurement and improve communication efficiency.

[0004] In a first aspect, a beam measurement method is provided. This method can be executed by a device (for example, a communication device). The device can be a device (such as a terminal device or a network device), or it can also be a component of the device (such as a chip or a chip system or a circuit). This application does not make any limitation in this regard. Hereinafter, the communication device will be mainly used as an example for illustration.

[0005] The method may include: receiving first indication information, where the first indication information indicates a first range within a candidate position set, the candidate position set includes a plurality of candidate positions, and the plurality of candidate positions correspond to a plurality of beams one by one; performing beam measurement on the beams corresponding to the candidate positions within the first range; and sending the result of the beam measurement.

[0006] Based on the above solution, by indicating a certain range (such as the first range) in the candidate position set, the indication of the beam to be measured can be realized. Specifically, there are a plurality of candidate positions in the candidate position set, and each candidate position corresponds to a beam. In this way, by indicating a range, the beams within this range can be indicated. Compared with indicating each beam, the above solution can reduce the indication overhead.

[0007] In combination with the first aspect, in some implementation manners of the first aspect, in a sensing scenario, the communication device determines the beams to be measured within the first range based on the sensing result.

[0008] Based on the above solution, the communication device performs beam measurement based on the sensing result of the reflector, avoiding the problem of excessive overhead caused by measuring all beams, thereby improving communication efficiency.

[0009] In combination with the first aspect, in some implementations of the first aspect, the method further includes: receiving a reference signal that is transmitted using a beam within a first range.

[0010] Based on the above solution, the communication device receives the reference signal transmitted using the beam within the first range, thereby improving communication efficiency.

[0011] In combination with the first aspect, in some implementations of the first aspect, the method further includes: receiving second indication information that indicates a set of candidate positions. Wherein, the set of candidate positions indicates at least one parameter of the beam.

[0012] It should be understood that the set of candidate positions can indicate a greater or lesser number of parameters.

[0013] Based on the above solution, the communication device determines the set of candidate positions by receiving the second indication information. The communication device can determine the first range based on the set of candidate positions and the first indication information, thereby determining the beam to be measured.

[0014] In combination with the first aspect, in some implementations of the first aspect, the interval between every two adjacent candidate positions in the set of candidate positions is the same; or, the candidate positions in the set of candidate positions are evenly distributed.

[0015] Based on the above solution, the candidate positions in the set of candidate positions are evenly distributed. This can not only discretize the relevant parameters of the beam through the set of candidate positions, but also simplify the indication content when indicating the first range because the candidate positions are evenly distributed, thereby reducing the indication overhead in the beam measurement process.

[0016] In combination with the first aspect, in some implementations of the first aspect, the set of candidate positions is used to represent at least one parameter of different beams, where the different beams have different beam widths.

[0017] In combination with the first aspect, in some implementations of the first aspect, the set of candidate positions is associated with numbers corresponding to the candidate positions one by one. Then the first indication information indicates the set of numbers of the candidate positions within the first range in the set of candidate positions, and the specific manner of numbering the candidate positions is not limited.

[0018] In another possible implementation, the first indication information includes at least one of the following:

[0019] (1) The number of the starting candidate position within the first range, the number of the ending candidate position within the first range; or,

[0020] (2) The number of the starting candidate position within the first range, the number of candidate positions within the first range.

[0021] Based on the above solution, the first indication information may indicate the numbers of candidate positions within the first range. For example, by indicating the number of the starting position and the quantity, the communication device can determine all candidate positions within the first range based on this indication, that is, determine the to-be-measured beam corresponding to the first range.

[0022] Combined with the first aspect, in some implementation manners of the first aspect, if the first range is circular, the first indication information includes the center position and / or radius of the circular first range.

[0023] In another possible implementation manner, if the first range is square, the first indication information includes at least one of the following: the position of one 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.

[0024] It should be understood that the first range determined by the communication device according to the first indication information may be in various shapes such as circular, square, elliptical, parallelogram, etc., and the present application does not make any limitation thereto.

[0025] Based on the above solution, the first indication information may 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 this indication, that is, determine the to-be-measured beam corresponding to the first range.

[0026] Combined with the first aspect, in some implementation manners 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, and the present application does not make any specific limitation to the specific numbering method.

[0027] Based on the above solution, the communication device numbers the candidate positions within the first range, that is, numbers the to-be-measured beams corresponding to the candidate positions within the first range, reducing the signaling overhead in the communication process.

[0028] Combined with the first aspect, in some implementation manners of the first aspect, the candidate position set is used to mark the spatial angle information of the 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, and the at least one parameter includes the zenith angle and / or the azimuth angle.

[0029] Based on the above solution, while discretizing the spatial angle information of the beam by using the candidate position set, the indication overhead for subsequently indicating the first range is reduced.

[0030] In combination with the first aspect, in some implementations of the first aspect, the result of 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 resources corresponding one-to-one to the beams within the first range, and the signal strength of the beams within the first range.

[0031] Based on the above solution, the communication device reports the result of beam measurement on the beam to be measured corresponding to the candidate position within the first range, thereby reducing the signaling overhead and reporting overhead.

[0032] In combination with the first aspect, in some implementations of the first aspect, the numbers of the measurement resources in the beam measurement resource set are numbered, and the present application does not limit the specific numbering method.

[0033] In combination with the first aspect, in some implementations of the first aspect, the communication device determines the number of beam measurement resources according to the number of candidate positions within the first range.

[0034] Based on the above solution, the communication device configures and numbers the beam measurement resources for the beam to be measured corresponding to the candidate position within the first range, and selects to perform transmission based on the number during the communication process, thereby reducing the signaling overhead.

[0035] In a second aspect, a beam measurement method is provided. This method can be executed by a device (for example, a communication device). The device can be a device (such as a terminal device or a network device), or it can also be a component of the device (such as a chip or a chip system or a circuit). The present application does not make a limitation in this regard. Hereinafter, the communication device will be mainly used as an example for illustration.

[0036] The method may include: sending a first indication message, where the first indication message indicates a first range within a candidate position set, the candidate position set includes a plurality of candidate positions, and the plurality of candidate positions correspond one-to-one to a plurality of beams; receiving the result of beam measurement, where the result of beam measurement is determined based on the beams within the first range.

[0037] In combination with the second aspect, in some implementations of the second aspect, in a sensing scenario, the communication device determines the beam to be measured within the first range based on the sensing result.

[0038] In combination with the second aspect, in some implementations of the second aspect, the method further includes: transmitting a reference signal using the beams within the first range.

[0039] In combination with the second aspect, in some implementations of the second aspect, the method further includes: sending a second indication message, where the second indication message indicates the candidate position set. Among them, the candidate position set indicates at least one parameter of the beam.

[0040] It should be understood that the candidate position set may indicate a greater or smaller number of parameters.

[0041] In combination with the second aspect, in some 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 evenly distributed.

[0042] In combination with the second aspect, in some implementations of the second aspect, the candidate position set is used to represent at least one parameter of different beams, where the different beams have different beam widths.

[0043] In combination with the second aspect, in some implementations of the second aspect, if the candidate position set configured by the communication device is provided with numbers corresponding to the candidate positions one by one, the first indication information indicates the set of candidate position numbers within the first range in the candidate position set, where the specific manner of numbering the candidate positions is not limited.

[0044] In another possible implementation, the first indication information includes at least one of the following:

[0045] (1) The number of the starting candidate position within the first range and the number of the ending candidate position within the first range;

[0046] (2) The number of the starting candidate position within the first range and the number of candidate positions within the first range.

[0047] In combination with the second aspect, in some implementations of the second aspect, if the first range is circular, the first indication information includes the center position and / or radius of the circular first range.

[0048] In another possible implementation, if the first range is square, the first indication information includes at least one of the following: the position of one 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.

[0049] It should be understood that the first range determined by the indication parameters configured by the communication device can be various shapes such as circular, square, elliptical, parallelogram, etc., and this application does not limit this.

[0050] In combination with the second aspect, in some 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, and this application does not specifically limit the specific numbering method.

[0051] In combination with the second aspect, in some implementations of the second aspect, the candidate position set is used to mark the spatial angle information of the 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, and the at least one parameter includes the zenith angle and / or the azimuth angle.

[0052] In combination with the second aspect, in some implementations of the second aspect, the result of beam measurement includes at least one of the following: the candidate position number corresponding to the beam within the first range, the number of beam measurement resources corresponding one-to-one to the beams within the first range, and the signal strength of the beams within the first range.

[0053] In combination with the second aspect, in some implementations of the second aspect, the number of candidate positions within the first range is the same as the number of beam measurement resources.

Among them, the satellite can refer to an unmanned aerial vehicle, a hot air balloon, a low-earth orbit satellite, a medium-earth orbit satellite, a geostationary orbit satellite, etc. The satellite can also refer to a non-ground base station or a non-ground device, etc.

[0086] The method in the embodiments of the present application can also be applied to scenarios where the network device and the terminal device have sensing capabilities.

[0087] With the increase in business requirements and the improvement of communication device capabilities, in some wireless communication systems, such as next-generation wireless communication systems (e.g., 6th Generation Mobile Communication Technology), network devices and terminal devices will have sensing capabilities, including self-transmitting and self-receiving modes and other-transmitting and self-receiving modes.

[0098] First, in combination with Figure 1 A communication system applicable to the embodiments of the present application will be briefly introduced as follows.

[0099] Figure 1 A schematic diagram of a wireless communication system applicable to the embodiments of the present application is shown. As Figure 1 shown, the wireless communication system includes a radio access network 100. The radio access network 100 can be a next-generation (e.g., 6G or higher) radio access network or a traditional (e.g., 5G, 4G, 3G, or 2G) radio access network. One or more terminal devices (such as terminal device 111, terminal device 112, terminal device 113, terminal device 114) can be connected to each other or connected to one or more network devices (such as network device 120) in the radio access network 100. As Figure 1 shown, 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 sensing results of effective reflectors.

[0100] Figure 1 This is just a schematic diagram. The wireless communication system may also include other devices, such as core network devices, wireless relay devices, and / or wireless backhaul devices, etc., which are not drawn in Figure 1 it.

[0101] Figure 2 A schematic diagram of beam measurement based on sensing results provided by the embodiments of the present application is shown. As Figure 2 shown, based on the sensing results of reflector 230, when network device 210 and terminal device 220 perform beam measurement, beams 241, 242, and 243 passing through reflector 230 are measured, and beams 240 and 244 not passing through reflector 230 are not measured.

[0102] For ease of understanding the embodiments of the present application, the terms involved in the present application will be briefly described.

[0103] 1. Beam: It can be understood as a spatial filter or spatial parameters. The beam used for transmitting 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 transmit angle (such as azimuth angle, zenith angle) or a spatial transmit angle range (such as azimuth center angle and offset, azimuth angle uncertainty, azimuth angle protection range, zenith center angle and offset, zenith angle uncertainty, zenith angle protection range), etc.; the beam used for receiving 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 receive angle (such as azimuth angle, zenith angle) or a spatial receive angle range (such as azimuth center angle and offset, azimuth angle uncertainty, azimuth angle protection range, zenith center angle and offset, zenith angle uncertainty, zenith angle protection range), etc.

[0104] The technology for forming a beam can be beamforming technology or other technologies. For example, beamforming technology can specifically be digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology, etc. The transmission beam can refer to the distribution of signal strength formed in different directions in space after the signal is transmitted by the antenna, and the reception beam can refer to the distribution of signal strength of the wireless signal received on the antenna in different directions in space. The beamforming technology of this application can be implemented based on a power amplifier of a new material or based on a new antenna architecture, such as new hybrid phased array and lens antenna technology.

[0105] 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 represent the same or similar meanings.

[0106] 2. Antenna panel: Abbreviated as panel. Each antenna panel can be configured with one or more reception beams and one or more transmission beams. Therefore, the antenna panel can also be understood as a beam group. A communication device, such as a terminal device or a network device, can receive signals through the reception beams on the antenna panel and can also transmit signals through the transmission beams on the antenna panel.

[0107] In the embodiments of the present application, for a terminal device, the panels can be distinguished by the resources of the uplink reference signal. The uplink reference signal can be a sounding reference signal (SRS). As an example rather than a limitation, one antenna panel can correspond to one SRS resource set identifier (ID). That is to say, one SRS resource set ID can be used to indicate one terminal device panel.

[0108] For a network device, the network devices can be distinguished by the panel ID. For example, the panel ID can be indicated by a transmission configuration indicator (TCI).

[0109] 3. Quasi-co-location (QCL): Or also known as quasi-same position. Antenna ports with 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 having a QCL relationship with this antenna port. Or, the difference between the channel parameters experienced by two antenna ports is less than a certain threshold.

[0110] Among them, an antenna port can also be simply referred to as a port, which refers to the transmitting antenna recognized by the receiving device, or the transmitting antennas that can be distinguished in space. One antenna port can be configured for each virtual antenna. Each virtual antenna can be a weighted combination of multiple physical antennas, and each antenna port can correspond to a reference signal port.

[0111] The above-mentioned channel parameters can include one or more of the following: delay spread, Doppler spread, Doppler shift, average delay, average gain, and spatial reception parameters. Among them, the spatial reception parameters can include, for example: angle of arrival, average AOA, AOA spread, angle of departure, average angle of departure AOD, AOD spread, receiving antenna spatial correlation parameters, transmitting antenna spatial correlation parameters, transmit beam, receive beam, and resource identifier.

[0112] The above-mentioned angle can be a decomposition value in different dimensions, or a combination of decomposition values in 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 for information transmission or reception within different time and / or frequency and / or code domain resources, and / or antenna ports with different antenna port numbers for information transmission or reception within different time and / or frequency and / or code domain resources. The above-mentioned resource identifier can be used to indicate the identifier on the resource. The resource identifier can include, for example, 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.

[0113] In the 5G-NR protocol, the QCL relationship can be divided into the following four types based on different parameters:

[0114] Type A: Doppler frequency shift, Doppler spread, average delay, delay spread;

[0115] Type B: Doppler frequency shift, Doppler spread;

[0116] Type C: Doppler frequency shift, average delay;

[0117] Type D: Spatial reception parameters.

[0118] The QCL involved in the embodiments of the present application is the QCL relationship of Type D. Unless otherwise specified hereinafter, QCL can be understood as the QCL of Type D, that is, the QCL defined based on spatial reception parameters. However, it should be understood that the present application does not exclude the possibility of defining other terms in future protocols to represent the same or similar meanings.

[0119] When the QCL relationship refers to the QCL relationship of Type D: The QCL relationship between the ports of the downlink signal and the ports of the downlink signal, or between the ports of the uplink signal and the ports of the uplink signal, can be that the two signals have the same AOA or AOD, which is used to represent having the same receiving beam or transmitting beam. Another example is that for the QCL relationship between the downlink signal and the uplink signal or between the ports of the uplink signal and the 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, the beam reciprocity can be utilized to determine the uplink transmission beam according to the downlink receiving beam, or determine the downlink receiving beam according to the uplink transmission beam.

[0120] The signal transmitted on the port with the spatial QCL relationship may also have corresponding beams, and the corresponding beams include at least one of the following: the same or nearly the same receive beam, the same or nearly the same transmit beam, the transmit beam corresponding to the receive beam (corresponding to the scenario with beam reciprocity), and the receive beam corresponding to the transmit beam (corresponding to the scenario with beam reciprocity).

[0121] The signal transmitted on the port with the spatial QCL relationship can also be understood as receiving or transmitting signals using the same spatial filter. The spatial filter can be at least one of the following: precoding, the weights of the antenna port, the phase deflection of the antenna port, and the amplitude gain of the antenna port.

[0122] The signal transmitted on the port with the 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.

[0123] Therefore, the spatial reception parameter (i.e., the QCL of type D) can be understood as a parameter for indicating the direction information of the receive and / or transmit beams.

[0124] 4. Beam pair link (BPL): The pairing relationship between the transmit beam and the receive beam, which can also be referred to as the pairing relationship between the spatial transmit filter and the spatial receive filter. Transmitting signals between the transmit beam and the receive beam with the beam pair relationship can obtain a large beamforming gain.

[0125] In a possible implementation, the sending end can send the reference signal by means of beam scanning, and the receiving end can also receive the reference signal by means of beam scanning. Specifically, the sending end can form beams with different directivities in space through beamforming, and can poll on multiple beams with different directivities to transmit the reference signal through the beams with different directivities, so that the power of the reference signal can reach the maximum in the direction pointed by the transmit beam. The receiving end can also form receive beams corresponding to different spatial directions and directivities through beamforming, and can poll on multiple beams with different directivities to receive the reference signal through the beams with different directivities, so that the power of the reference signal received by the receiving end can reach the maximum in the direction pointed by the receive beam.

[0126] By traversing each transmit beam and receive beam, the receiving end can perform channel measurements based on the received reference signals and report the measurement results to the transmitting end. For example, the receiving end can report the reference signal resources with larger reference signal receiving power (RSRP) to the transmitting end, such as reporting the identifiers of the reference signal resources, so that the transmitting end can use the beam pairing relationship with better channel quality to transmit and receive signals when transmitting data or signaling.

[0127] 5. Reference Signal (RS) and Reference Signal Resource (RS Resource): The reference signal can be used for channel measurement, channel estimation, or beam quality monitoring, etc. The reference signal resource can be used to configure the transmission attributes of the reference signal. For example, time-frequency resource location, port mapping relationship, power factor, and scrambling code, etc. The transmitting end device can transmit the reference signal based on the reference signal resource, and the receiving end device can receive the reference signal based on the reference signal resource.

[0128] The reference signals involved in the embodiments of this application can include, for example, channel state information reference signal (CSI-RS), synchronization signal block (SSB), and sounding reference signal. Correspondingly, the reference signal resources can include CSI-RS resource (CSI-RS resource), SSB resource, and SRS resource (SRS resource).

[0129] To distinguish different reference signal resources, each reference signal resource can correspond to an identifier of the reference signal resource. For example, CSI-RS resource indicator (CRI), SSB resource indicator (SSBRI), and SRS resource index (SRI).

[0130] It should be noted that the above 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 description, without special instructions, the SSB resources and the SS / PBCH block resources may represent the same meaning, and the SSB resources and the SS / PBCH block resources may represent the same meaning. In addition, in some cases, SSB may also refer to the SSB resources. Therefore, the SSB resource identifier is sometimes also referred to as the SSB identifier (SSB index).

[0131] It should be understood that the reference signals and the corresponding reference signal resources listed above are only for illustrative purposes and should not constitute any limitation to the present application. The present application does not exclude the possibility of defining other reference signals in future protocols to achieve the same or similar functions.

[0132] In the configuration signaling of the reference signal resources, different time domain behavior parameters can be used to indicate different time domain behaviors. By way of example and not limitation, the time domain behaviors may include, for example, periodic, semi-persistent (SP), and aperiodic (AP).

[0133] 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.

[0134] 6. Transmission Configuration Indicator (TCI) state: It can be used to indicate the QCL relationship between two reference signals. The TCI state can be used by the terminal device to determine the receiving beam of the downlink signal or the downlink channel.

[0135] Each TCI state may include a reference signal resource identifier. Among them, the reference signal resource identifier may be, for example, at least one of the following: non-zero power (NZP) channel state information (CSI-RS) resource identifier (NZP-CSI-RS-ResourceId) or SSB index (SSB-Index).

[0136] 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 correspondence between the reference signal resource identifier and the receive beam, and the network device can maintain the correspondence between the reference signal resource identifier and the transmit beam. Through the reference signal resource identifier, the pairing relationship between the receive beam and the transmit beam can be established.

[0137] During the subsequent communication process, the terminal device can determine the receive beam based on the TCI state indicated by the network device, and the network device can determine the transmit beam based on the same TCI state.

[0138] It should be understood that the information included in the TCI states listed here is only an example and should not impose any limitation on this application. For example, the TCI state may also include the index of the serving cell (ServeCellIndex), the identifier (ID) of the bandwidth part (BWP), etc. Since the embodiments of this application do not involve serving cells and BWPs, no detailed description is given here.

[0139] 7. Spatial relation (SR): It can also be referred to as uplink TCI (UL TCI). Similar to the TCI introduced above, the spatial relation can be used by the terminal device to determine the transmit beam of the uplink signal or uplink channel.

[0140] Each spatial relation may include a reference signal resource identifier. Among them, the reference signal resource identifier can be, for example, any one of the following: SSB index (SSB-Index), non-zero power CSI-RS reference signal resource identifier (NZP-CSI-RS-ResourceId), and SRS resource identifier (SRS-ResourceId).

[0141] Among them, the reference signal resource identifier refers to the reference signal resource used during beam training. A spatial relationship is used to determine a transmission beam. The terminal device can maintain the correspondence between the reference signal resource identifier and the transmission beam during beam training, and the network device can maintain the correspondence between the reference signal resource identifier and the reception beam during beam training. Through the reference signal resource identifier, the pairing relationship between the transmission beam and the reception beam can be established.

[0142] During 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 reception beam based on the same spatial relationship.

[0143] In addition, each spatial relationship may further include power control information. The power control information may include, for example, at least one of the following: desired received power, path loss reference signal, and path loss compensation parameter. The terminal device can determine the transmission power for transmitting the uplink signal based on the power control information.

[0144] 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 further include the index of the serving cell (ServeCellIndex), the identifier (ID) of the bandwidth part (BWP), etc. Since the embodiments of this application do not involve the serving cell and BWP, no detailed description is given here.

[0145] The beam alignment between the terminal device and the network device can be achieved through information interaction. The terminal device can perform beam measurement based on the reference signal sent by the network device (e.g., SSB or channel state information reference signal (CSI-RS)), and report the reference signal numbers corresponding to one or more beams and the beam quality information (e.g., 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 serving beam and / or the QCL relationship between the reference signal resource number corresponding to the serving beam and the reference signal resource number corresponding to the measurement beam for subsequent data transmission. To ensure the beam alignment state between the network device and the terminal device, the above information interaction between the terminal device and the network device is usually carried out continuously.

[0146] In addition, current wireless communication systems have introduced higher-frequency spectrum resources, such as millimeter wave and terahertz bands, to meet the growing communication demands. Generally, at higher frequency bands, the path loss experienced by wireless signals is relatively large, which affects the coverage distance of wireless signals. In the millimeter wave and terahertz bands, beamforming technology can be used to concentrate the signal energy into a specific angular range, thereby increasing the coverage distance of wireless signals.

[0147] Before introducing the solution of this application, the following points are noted.

[0148] (1) In this application, "indication" may include direct indication, indirect indication, display indication, and implicit indication. When it is described 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.

[0149] In this application, the information indicated by the indication information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated. For example, 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. It can also indirectly indicate the information to be indicated by indicating other information, where there is an association relationship between the other information and the information to be indicated. It can also only indicate a part of the information to be indicated, while the other parts of the information to be indicated are known or pre-agreed. For example, it is also possible to achieve the indication of specific information by relying on the arrangement order of each pre-agreed (such as protocol-defined) information, thereby reducing the indication overhead to a certain extent. In addition, the information to be indicated can be sent as a whole, or divided into multiple sub-information and sent separately, and the sending periods and / or sending timings of these sub-information can be the same or different.

[0150] (2) In this application, "send" and "receive" represent the direction of signal transmission. For example, "sending information to XX" can be understood as the destination of the information is XX, which can include directly sending through the air interface, and also include other units or modules indirectly sending through the air interface. "Receiving information from YY" can be understood as the source of the information is YY, which can include directly receiving from YY through the air interface, and can also include indirectly receiving from YY through the air interface from other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" 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 a device through a bus, trace or interface.

[0151] (3) In various embodiments of the present application, if there is no special description and logical conflict, the terms and / or descriptions between different embodiments are consistent and can be cross-referenced to each other. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0152] (4) In the present application, "first" and "second" are only for the convenience of description and are used to distinguish objects, rather than to limit the scope of the embodiments of the present application. They are not used to describe the order or sequence of features. It should be understood that the objects described in this way can be interchanged under appropriate circumstances so as to be able to describe the solutions other than the embodiments of the present application.

[0153] The method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments provided by the present application can be applied to the communication system shown above Figure 1 without limitation.

[0154] In the following embodiments, the terminal device and the network device are taken as examples for illustrative purposes.

[0155] Among them, the terminal device can be replaced by the components of the terminal device (such as chips or circuits), or the network device, or the components of the network device (such as chips or circuits). The network device can be replaced by the components of the network device (such as chips or circuits), or the terminal device, or the components of the terminal device (such as chips or circuits).

[0156] Figure 3 Fig. shows a schematic diagram of a communication method provided by an embodiment of the present application. Figure 3 The method 300 shown may include the following steps.

[0157] Optionally, the method 300 includes step S301.

[0158] S301, the network device sends indication information #A (i.e., an example of the second indication information), and correspondingly, the terminal device receives the indication information #A.

[0159] As an example, the indication information #A is carried in any one of the following: radio resource control (RRC) signaling, system messages (such as, master information block (MIB) or system information block (SIB)).

[0160] Among them, the indication information #A indicates a set of candidate positions. The set of candidate positions includes multiple candidate positions, and the multiple candidate positions correspond to multiple beams one by one. That is, one candidate position can correspond to one beam, and the beams corresponding to different candidate positions are different. For example, the beams corresponding to different candidate positions have different angles.

[0161] As an example, the set of candidate positions can be a set of candidate angles.

[0162] Among them, the set of candidate positions can also be referred to as a position set, or an airspace grid, or a grid, or a network, or an airspace mesh. There is no limitation on its naming. Hereinafter, it is uniformly described as an airspace grid, and the candidate positions in the set of candidate positions are called grid points.

[0163] Optionally, the airspace grid can be in the form of coordinates. For example, the airspace grid is a two-dimensional coordinate, and the abscissa and ordinate of the airspace grid can be the beam angle information of the beam. This beam angle information can also be referred to as beam angle range information or angle range information, etc. For example, the abscissa of the airspace grid is the first parameter, and the ordinate is the second parameter. Among them, 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. Among them, 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.

[0164] In the embodiments of the present application, the first parameter and the second parameter are mainly used as examples for illustration, and there is no limitation thereto. For example, more or fewer parameters can be indicated in the airspace grid.

[0165] The network side can configure and / or indicate the airspace grid, or the airspace grid can also be predefined by the protocol. The embodiments of the present application do not limit this.

[0166] In a possible implementation, the airspace grid is uniform. For example, the indication information #A indicates a uniform airspace grid, that is, the airspace grid indicated by the indication information #A is a uniform airspace grid. Among them, the intervals between every two adjacent grid points in the uniform airspace grid are the same, or the grid points in the uniform airspace grid are evenly distributed.

[0167] It should be understood that the intervals between every two adjacent grid points in the uniform airspace grid are the same, that is, the value intervals of two adjacent first parameters in the airspace grid are the same, and the value intervals of two adjacent second parameters in the airspace grid are the same.

[0168] In another possible implementation, the spatial grid is non-uniform. For example, the indication information #A indicates a non-uniform spatial grid, that is, the spatial grid indicated by the indication information #A is a non-uniform spatial grid. Among them, the intervals between every two adjacent grid points in the non-uniform spatial grid are different, or the grid points in the non-uniform spatial grid are non-uniformly distributed.

[0169] It should be understood that the intervals between every two adjacent grid points in the non-uniform spatial grid are different, that is, the value intervals of two adjacent first parameters in the spatial grid are not exactly the same, and / or the value intervals of two adjacent second parameters in the spatial grid are not exactly the same.

[0170] Figure 4 The schematic diagram of the spatial grid provided by the embodiment of the present application is shown. As Figure 4 shown in it, it is assumed that the abscissa is the azimuth angle and the ordinate is the zenith angle.

[0171] As Figure 4 shown in (a) of it, the spatial grid is a uniform spatial grid, that is, the intervals between two adjacent azimuth angles are the same, and the intervals between two adjacent zenith angles are also the same. It is assumed that the angle range of the azimuth angle is [-40, 40], the step size is 5, and the abscissa includes 17 values; it is assumed that the angle range of the zenith angle is [100, 128], the step size is 4, and the ordinate includes 8 values. Based on the set values of the azimuth angle and the zenith angle, the grid points in the uniform spatial grid can be formed. At least one of the zenith angle and the azimuth angle corresponding to different grid points may be different.

[0172] It should be understood that Figure 4 the uniform spatial grid shown in (a) of it is only an example, and the specific parameter selection of the abscissa or the ordinate, the value range and the step size of the azimuth angle or the zenith angle can be configured by the network device according to the actual beam coverage range, coverage distance or antenna scale, and the embodiment of the present application does not limit this.

[0173] As Figure 4 shown in (b) of it, the spatial grid is a non-uniform spatial grid, that is, the intervals between two adjacent azimuth angles are not exactly the same, and the intervals between two adjacent zenith angles are also not exactly the same.

[0174] In a possible implementation, the non-uniform spatial grid is applied to the scenario where the network device uses narrow beams to cover the cell edge and wide beams to cover the cell center. That is, the non-uniform spatial grid is used to indicate at least one parameter of different beams, where different beams refer to different beam widths.

[0175] It should be understood that Figure 4The non-uniform spatial domain grid shown in (b) is only an example. For the specific parameter selection of the abscissa or ordinate, the network device can configure it according to the actual application scenario, the actual beam coverage range, the coverage distance, or the antenna scale. The embodiments of the present application do not limit this.

[0176] S302. The network device sends indication information #B (an example of the first indication information). Correspondingly, the terminal device receives the indication information #B.

[0177] Among them, the indication information #B indicates the beam range to be measured (or simply referred to as the beam range, that 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.

[0178] Figure 5 FIG. shows a schematic diagram of indicating the beam range by taking a uniform spatial domain grid as an example provided by the embodiments of the present application. The following combines Figure 5 to introduce the implementation manner of the indication information #B indicating the beam range.

[0179] Method 1: The indication information #B includes relevant parameters indicating the beam range.

[0180] As an example, Method 1 can be applied to the case of a uniform spatial domain grid.

[0181] In a possible implementation manner, 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 according to the received indication information #B, and then determines the beams to be measured within the circle.

[0182] Exemplarily, the relevant parameters of the circle include at least one of the following: the center position, the radius (or referred to as the offset).

[0183] For example, the indication information #B includes the center position and the radius. Among them, the center position 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.

[0184] As Figure 5 shown in (a), the beam range is the range indicated by the dotted line. The network device indicates the center position of the beam range to the terminal device, that is, the central angle, that is, the central azimuth angle and the central zenith angle, and the radius. In this way, when the terminal device receives the indication information #B, it determines the same circular beam range as the network device side in the uniform spatial domain grid according to the indication information #B, and then determines the beams within the circular beam range. The beams within this beam range are the beams to be measured.

[0185] As an example, the number of bits occupied by the center position of the circle (such as the central angle) and the radius can satisfy formulas (1)-(3).

[0186]

[0187]

[0188]

[0189] Among them, is the ceiling function.

[0190] In another possible implementation, the beam range is square, and the indication information #B sent by the network device includes the relevant parameters of the square. Therefore, the terminal device determines the square according to the received indication information #B, and further determines the beams to be measured within the square.

[0191] Exemplarily, the relevant parameters of the square include at least one of the following: the position of one corner of the square, the length of the square, the width of the square, the central position of the length of the square, and the central position of the width of the square. For ease of understanding, an exemplary explanation is given in the following manner.

[0192] Method 1

[0193] For example, the indication information #B includes the starting position of the square, the length of the square, and the width of the square. Among them, the starting position of the square is used to determine the position of the square beam range, and the length and width of the square are used to determine the size of the square beam range.

[0194] As Figure 5 shown in (b) of, the beam range is the range indicated by the dashed line. The network device indicates the starting azimuth angle and starting zenith angle of the square beam range to the terminal device, as well as the width and length of the square beam range. In this way, when the terminal device receives the indication information #B, it determines the same square beam range as on the network device side in the uniform airspace grid, and further determines the beams within the square beam range. The beams within this beam range are the beams to be measured.

[0195] As an example, the number of bits occupied by the position of one corner of the square (such as the starting azimuth angle and starting zenith 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).

[0196]

[0197]

[0198]

[0199]

[0200] Among them, is rounding up.

[0201] Method 2

[0202] For example, the indication information #B includes the central position of the length of the square, the offset of the length of the square, the central position of the width of the square, and the offset of the width of the square.

[0203] When used to represent the relevant parameters of the square, the offset refers to half of a certain side length of the square.

[0204] Such as Figure 5 shown in (c) of, the beam range is the range indicated by the dotted line. The network device indicates the central angle of the zenith angle, the offset of the zenith angle direction from the central angle, the central angle of the azimuth angle, and the offset of the azimuth angle direction from the central angle to the terminal device. In this way, the terminal device receives the indication information #B, determines the same square beam range as that on the network device side in the uniform airspace grid according to the indication information #B, and then determines the beams within the square beam range. The beams within this beam range are the beams to be measured.

[0205] The calculation method of the number of bits occupied by the relevant parameters will not be elaborated here.

[0206] Optionally, the shape of the beam range indicated by the indication information #B can also be an ellipse, a parallelogram, etc. The embodiments of the present application do not limit this. It is only required that all the beams to be measured are included in the beam range indicated by the indication information #B.

[0207] 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. Among them, the number of the grid point can also be called an index. As an example, the grid points can be numbered sequentially starting from 0 or other values in the order of abscissa and then ordinate; or, the grid points can be numbered sequentially starting from 0 or other values in the order of ordinate and then abscissa. The following is combined with Figure 6 for illustration.

[0208] Figure 6 shows an example diagram of numbering the grid points within the circular beam range in the embodiments of the present application using a uniform airspace grid as an example.

[0209] In a possible implementation manner, the network device configures a uniform airspace grid as shown in Figure 6 . The range indicated by the dotted line is the beam range, and the grid points within the beam range are numbered.

[0210] Optionally, the grid points within the beam are numbered first along the azimuth angle and then along the zenith angle. For example, Figure 6 as shown, the set of grid point numbers within the beam can be obtained as {0, 1, 2, …, 20}.

[0211] In another possible implementation, the terminal device numbers the grid points within the beam to obtain the set of grid point numbers within the beam.

[0212] It should be understood that the airspace grid can also indicate a smaller or larger number of parameters. For different situations, there are more choices for the specific numbering method, which is not limited in the embodiments of the present application.

[0213] Method 2: The indication information #B indicates the numbers of the grid points within the beam.

[0214] In one possible implementation, the indication information #B includes the numbers of each grid point within the beam.

[0215] In another possible implementation, the indication information #B includes at least one of the following:

[0216] (1) The number of the starting grid point within the beam, the number of the ending grid point within the beam; or,

[0217] (2) The number of the starting grid point within the beam, the number of grid points within the beam.

[0218] Through the above at least one item, the numbers of each grid point within the beam can be obtained.

[0219] As an example, Method 2 can be applied to both uniform airspace grids and non-uniform airspace grids.

[0220] Figure 7 FIG. shows a schematic diagram of indicating the beam range in the embodiments of the present application taking a uniform airspace grid as an example. The following will introduce Method 2 in combination with Figure 7 to introduce Method 2.

[0221] It is assumed that the grid points are numbered first along the azimuth angle direction and then along the zenith angle direction.

[0222] In one possible way, after the network device determines the beam range in the airspace grid in step S302, it directly sends the numbers of the grid points within the beam to the terminal device, that is, the indication information #B includes the numbers of all grid points within the beam, 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}.

[0223] 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; alternatively, the indication information #B includes the number 21 of the starting grid point within the beam range and the number 21 of the grid points within the beam range.

[0224] S303. The network device sends a reference signal. Correspondingly, the terminal device receives the reference signal.

[0225] The reference signal can also be referred to as a pilot or a pilot sequence, and can be used for channel estimation in a communication system.

[0226] Specifically, after determining the beam range, the network device sends multiple reference signals based on the beams within the beam range; correspondingly, the terminal device receives the reference signals sent by the network device and performs beam measurement.

[0227] Based on this solution, the network device sends reference signals for the beams to be measured within the beam range, thereby reducing communication overhead. And the terminal device receives the reference signals sent by the network device and performs beam measurement, improving the efficiency of beam measurement.

[0228] S304. The terminal device determines beam measurement resources.

[0229] Specifically, the terminal device determines beam measurement resources according to the received reference signals.

[0230] Optionally, the beam measurement resources include time-frequency resources.

[0231] The grid points within the beam range should correspond one-to-one with 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, and N is an integer.

[0232] In one possible implementation, the numbering method of the beam measurement resources can refer to the method of numbering the grid points within the beam range as in Figure 6 such that the numbers of the grid points within the beam range correspond one-to-one with the numbers of the beam measurement resources.

[0233] It should be understood that numbering the beam measurement resources can also be understood as configuring an index for the beam measurement resources, 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.

[0234] S305. The terminal device sends the result of beam measurement. Correspondingly, the network device receives the result of beam measurement.

[0235] Specifically, the terminal device reports the determined beam measurement resources as the result of beam measurement.

[0236] In addition, the result of beam measurement further includes 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 corresponding one-to-one to the beam within the beam range determined by the terminal device, 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.

[0237] Optionally, the result of beam measurement includes the determined time-frequency resource.

[0238] Exemplarily, the i-th time-frequency resource is located in the (i + offset)-th OFDM symbol, where i = 0, …, N - 1, N is the number of beam measurement resources, and offset is the time-domain offset. As an example, offset may be 0.

[0239] Optionally, the result of beam measurement includes the bit width, and the bit width represents the number of bits occupied by transmitting the beam measurement resource.

[0240] Exemplarily, the bit width satisfies formula (8):

[0241]

[0242] where is the ceiling function, and N is the number of beam measurement resources.

[0243] For ease of understanding, several possible application scenarios of application method 300 are introduced below.

[0244] Figure 8 is a schematic diagram of configuring beam measurement resources based on a uniform spatial grid and a circular beam range in a sensing scenario provided by an embodiment of the present application.

[0245] As Figure 8 shown in (a) of, the network device 810 configures or predefines a uniform spatial grid, and this uniform spatial grid can indicate the angle information of the beam. The network device 810 may send indication information #A to the terminal device 820 to indicate this uniform spatial grid.

[0246] In a possible implementation manner, as Figure 8 shown in (a) of, based on the fact that the reflection surface of the effective reflector is circular, the network device 810 and the terminal device 820 measure the beam based on the sensing result.

[0247] The network device 810 determines the beam range in the uniform spatial grid according to the beam to be measured, such as Figure 8 the range indicated by the dotted line in the uniform spatial grid in (a) of. It can be seen that this beam range is circular.

[0248] The network device 810 sends indication information #B, and the indication information #B includes the center position (i.e., the central azimuth angle and the central zenith angle) and the radius. Among them, all the beams to be measured are included in the beam range determined according to the indication information #B. The specific method for determining the relevant parameters will not be elaborated here.

[0249] The network device 810 uses the beams within the beam range to send reference signals.

[0250] The terminal device 820 can determine the same beam range as the network side according to the indication information #A and the indication information #B, and perform beam measurement based on the reference signals sent by the network device 810.

[0251] The network device 810 and the terminal device 820 number the grid points within the beam range based on the same numbering method (such as first the abscissa and then the ordinate, or first the ordinate and then the abscissa). The numbering order is to number along the azimuth angle direction first, 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, N is an integer, and here N is 21. Among them, the numbering method can be indicated by the network device 810 to the terminal device 820, or can be predefined.

[0252] Figure 8 In (b) shows a schematic diagram of the terminal device 820 determining the beam measurement time-frequency resources. The beam measurement time-frequency resources are numbered, and the numbering method can refer to Figure 6 the numbering method of the grid points within the beam range shown in, which will not be elaborated here.

[0253] The grid point numbers within the beam range correspond one-to-one with the numbers of the beam measurement time-frequency resources, that is, the number N of the grid points within the beam range is the number of the beam measurement time-frequency resources. For example Figure 8 the 21 grid points within the beam range shown in (a) in Figure 8 correspond to the 21 beam measurement time-frequency resources shown in (b) in

[0254] The terminal device 820 reports the results of the beam measurement.

[0255] Figure 9 is a schematic diagram of configuring beam measurement resources based on a uniform spatial grid and a square beam range in a sensing scenario provided by an embodiment of the present application.

[0256] Such as Figure 9 shown in (a) in, the network device 910 configures or predefines a uniform spatial grid, and this uniform spatial grid can indicate the angle information of the beam. The network device 910 can send indication information #A to the terminal device 920 to indicate this uniform spatial grid.

[0257] In a possible implementation, as shown in Figure 9 (a) of FIG. [FIGURE NUMBER], the reflecting surface based on the effective reflector is square, and the network device 910 and the terminal device 920 measure the beams based on the sensing results.

[0258] The network device 910 determines the beam range in the uniform spatial grid according to the beam to be measured, such as Figure 9 the range indicated by the dotted line in the uniform spatial grid in (a) of FIG. [FIGURE NUMBER]. It can be seen that this beam range is square.

[0259] The network device 910 sends indication information #B, and the indication information #B includes the position of one corner of the square (such as the starting azimuth angle and the starting zenith angle), the width of the square (the square width in the azimuth direction), and the length of the square (the square length in the zenith direction). Among them, all the beams to be measured are included in the beam range determined according to the indication information #B. The specific method for determining the relevant parameters will not be elaborated here.

[0260] The network device 910 uses the beams within the beam range to send reference signals.

[0261] The terminal device 920 can determine the same beam range as the network side according to the indication information #A and the indication information #B, and perform beam measurement based on the reference signal sent by the network device 910.

[0262] The network device 910 and the terminal device 920 number the grid points within the beam range based on the same numbering method (such as first the abscissa and then the ordinate, or first the ordinate and then the abscissa). The numbering order is to number along the azimuth direction first, and then along the zenith 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. Here, N is 15. Among them, the numbering method can be indicated by the network device 910 to the terminal device 920, or it can be predefined.

[0263] Figure 9 (b) of FIG. [FIGURE NUMBER] shows a schematic diagram of the terminal device 920 determining the beam measurement time-frequency resources. The beam measurement time-frequency resources are numbered, and the numbering method can refer to Figure 6 the numbering method for the grid points within the beam range shown in FIG. [FIGURE NUMBER], which will not be elaborated here.

[0264] It should be understood that the numbering of the grid points within the beam range corresponds one-to-one with the numbering of 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, Figure 9 the 15 grid points within the beam range shown in (a) of FIG. [FIGURE NUMBER] correspond to Figure 9 the 15 beam measurement time-frequency resources shown in (b) of FIG. [FIGURE NUMBER]. Please note that the [FIGURE NUMBER] in the translation should be replaced with the actual figure number in the original patent text.

[0265] The terminal device 920 reports the results of beam measurement.

[0266] Figure 10 It is a schematic diagram of configuring beam measurement resources based on a uniform airspace grid in a sensing scenario provided by an embodiment of the present application.

[0267] In a possible implementation, as shown in (a) of Figure 10 , the network device 1010 configures or pre - defines a uniform airspace grid, and the uniform airspace grid can indicate the angle information of the beam. The network device numbers all the grid points in the uniform airspace grid, and then sends indication information #A to the terminal device 1020 to indicate the uniform airspace grid.

[0268] In a possible implementation, as shown in (a) of Figure 8 , 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.

[0269] The network device 1010 determines the beam range in the uniform airspace grid according to the beam to be measured, such as the range indicated by the dotted line in the uniform airspace grid in (a) of Figure 10 .

[0270] The network device 1010 sends indication information #B, and the indication information #B includes:

[0271] {21, 22, 23, 37, 38, 39, 40, 41, 54, 55, 56, 57, 58, 71, 72, 73, 74, 75, 89, 90, 91}.

[0272] Among them, according to the indication information #B, it includes the numbers of all the beams to be measured. That is, the indication information #B includes N sets of grid point numbers, N is an integer, and here N is 21.

[0273] The network device 1010 uses the beams within the beam range to send reference signals.

[0274] The terminal device 1020 can determine the same beam range as the network side according to the indication information #A and the indication information #B, and perform beam measurement based on the reference signal sent by the network device 1010.

[0275] Figure 10 (b) in Figure 6 shows a schematic diagram of the terminal device 1020 determining the time - frequency resources for beam measurement. The time - frequency resources for beam measurement are numbered, and the numbering method can refer to the method of numbering the grid points within the beam range shown in

[0276] It should be understood that the grid point numbers within the beam range correspond one-to-one with the numbers of the beam measurement time-frequency resources, that is, the number N of grid points within the beam range is the number of beam measurement time-frequency resources. For example Figure 10 the 21 grid points within the beam range shown in (a) of Figure 10 correspond to the 21 beam measurement time-frequency resources shown in (b) of

[0277] The terminal device 1020 reports the results of beam measurement.

[0278] Figure 11 FIG. is a schematic diagram of configuring beam measurement resources based on non-uniform airspace grid and circular beam range in a sensing scenario provided by an embodiment of the present application.

[0279] In a possible implementation, the network device 1110 uses narrow beams to cover the cell edge and wide beams to cover the cell center.

[0280] Based on such beam arrangement, as Figure 11 shown in (a) of, the network device 1110 configures or pre-defines a non-uniform airspace grid, and this non-uniform airspace grid can indicate the angle information of the beam. The network device 1110 can send indication information #A to the terminal device 1120 to indicate this non-uniform airspace grid.

[0281] In a possible implementation, as Figure 11 shown in (a) of, the network device 1110 pre-configures the first parameter and the second parameter (i.e., zenith angle and azimuth angle) of all beams. Based on the fact that the reflecting surface of the effective reflector is circular, the network device 1110 and the terminal device 1120 measure the beams based on the sensing results, and do not measure the beams that do not pass through the reflector.

[0282] The network device 1110 determines the beam range in the airspace grid according to the beam to be measured. As Figure 11 the range indicated by the dotted line in the non-uniform airspace grid in (a) of, it can be seen that this beam range is circular, where the grid points outside the beam range correspond to the beams that do not pass through the reflector.

[0283] The network device 1110 sends indication information #B, and the indication information #B includes the center position (i.e., the center azimuth angle and the center zenith angle) and the radius. Among them, the beam range determined according to the indication information #B includes all beams to be measured. The specific method for determining the relevant parameters will not be elaborated here.

[0284] The network device 1110 uses the beams within the beam range to send reference signals.

[0285] The terminal device 1120 can determine the same beam range as the network side according to the indication information #A and the indication information #B, and perform beam measurement based on the reference signal sent by the network device 1110.

[0286] The network device 1110 and the terminal device 1120 number the grid points within the beam range based on the same numbering method (such as first the abscissa and then the ordinate, or first the ordinate and then the abscissa). The numbering order is to number along the azimuth direction first 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 here N is 4. Among them, the numbering method can be indicated by the network device 1110 to the terminal device 1120 or can be predefined.

[0287] Figure 11 (b) in shows a schematic diagram of determining the beam measurement time-frequency resources based on the grid points within the beam range. Number the beam measurement time-frequency resources, and the numbering method can refer to Figure 6 the numbering method of the grid points within the beam range shown in, which will not be elaborated here.

[0288] The grid point numbers within the beam range correspond one-to-one with the numbers of 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 Figure 11 the 4 grid points within the beam range shown in (a) in correspond to Figure 11 the 4 beam measurement time-frequency resources shown in (b) in.

[0289] The terminal device 1120 reports the results of the beam measurement.

[0290] Figure 12 is a schematic diagram of configuring beam measurement resources based on an airspace position grid and a circular beam range provided by an embodiment of the present application.

[0291] As Figure 12 shown in (a) in, the network device 1210 configures or predefines an airspace position grid, and this airspace position grid can indicate the ground position covered by the beam.

[0292] Optionally, based on the ground position, assume that the abscissa of the airspace position grid is the X-axis and the ordinate is the Y-axis, and the grid points in this airspace position grid are evenly distributed.

[0293] It should be understood that Figure 12 the uniform airspace position grid shown in (a) in is only an example. The specific setting of the abscissa or ordinate, the value range and step size of the X-axis and the Y-axis can be configured by the network device 1210 according to the actual beam coverage range, coverage distance or antenna scale. The embodiments of the present application do not limit this.

[0294] The network device 1210 sends indication information #A to the terminal device 1220 to indicate the uniform airspace position grid.

[0295] In a possible implementation, as Figure 12 shown in (a) of, 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 sensing results, and do not measure the beams that do not pass through the reflector.

[0296] The network device 1210 determines the beam range in the uniform airspace position grid according to the beam to be measured. As Figure 12 shown by the range indicated by the dotted line in the uniform airspace position grid in (a) of, it can be seen that the beam range is circular. Among them, the grid points outside the beam range correspond to the beams that do not pass through the reflector.

[0297] The network device 1210 sends indication information #B, and the indication information #B includes the center position (i.e., the center X-axis position and the center Y-axis position) and the radius. Among them, the beam range determined according to the indication information #B includes all the beams to be measured. The specific method for determining the relevant parameters will not be elaborated here.

[0298] The network device 1210 uses the beams within the beam range to send reference signals.

[0299] The terminal device 1220 can determine the same beam range as the network side according to the indication information #A and the indication information #B, and perform beam measurement based on the reference signal sent by the network device 1210.

[0300] The network device 1210 and the terminal device 1220 number the grid points within the beam range based on the same numbering method (such as first the abscissa and then the ordinate, or first the ordinate and then the abscissa). The numbering order is to number along the X-axis direction first, and then along the Y-axis direction. 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, N is an integer, and here N is 10. Among them, the numbering method can be indicated by the network device 1210 to the terminal device 1220, or can be predefined.

[0301] Figure 12 Shown in (b) of is a schematic diagram for determining the beam measurement time-frequency resources based on the grid points within the beam range. Number the beam measurement time-frequency resources, and the numbering method can refer to Figure 6 the numbering method for the grid points within the beam range shown in, which will not be elaborated here.

[0302] The grid point numbers within the beam range correspond one-to-one with the numbers of the beam measurement time-frequency resources, that is, the number N of grid points within the beam range is the number of beam measurement time-frequency resources. For example, Figure 12 the 10 grid points within the beam range shown in (a) of Figure 12 correspond to the 10 beam measurement time-frequency resources shown in (b) of

[0303] In another possible implementation, the network device configures a non-uniform airspace position grid for the terminal device, that is, based on the ground position, the abscissa is set as the X-axis and the ordinate is set as the Y-axis, and the grid points in this airspace position grid are non-uniformly distributed.

[0304] The terminal device 1220 reports the results of beam measurement.
