Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to communication methods and related devices. Background Art

[0002] Perception technology is a technology for detecting, tracking and imaging targets. It sends radio waves in a specific direction through the transmitter. When the radio waves hit the target surface, they form reflected radio waves. The receiver processes the received reflected radio waves to obtain information such as the target's position, speed, shape and type.

[0003] The higher the perception accuracy and resolution, the better. Therefore, how to achieve high-precision and high-resolution perception is a technical problem that needs to be solved urgently. Summary of the Invention

[0004] This application provides a communication method and related devices that help improve perception accuracy and perception resolution.

[0005] In a first aspect, the present application provides a communication method, which is applied to a first communication device. The method includes: sending first information indicating a first frequency domain resource, the first frequency domain resource corresponding to the same spatial domain processing parameter; and sending or receiving a first signal on the first frequency domain resource.

[0006] In this method, a first communication device indicates to a second communication device via first information which frequency domain resources correspond to the same spatial processing parameters, and transmits signals on these frequency domain resources corresponding to the same spatial processing parameters, so that the second communication device can learn which frequency domain resources correspond to the same spatial processing parameters and thus perform joint perception based on the signals on these frequency domain resources with the same spatial processing parameters. Because joint perception based on the signals on the frequency domain resources with the same spatial processing parameters can improve perception accuracy and resolution, this method helps improve perception accuracy and resolution.

[0007] From another perspective, the first communication device indicates to the second communication device through the first information which frequency domain resources correspond to the same spatial domain processing parameters, and sends signals on these frequency domain resources corresponding to the corresponding spatial domain processing parameters, providing technical support or the possibility of implementation for high-precision perception and high-resolution perception.

[0008] In some possible implementations, the first frequency domain resource belongs to the second frequency domain resource. Sending or receiving the first signal on the first frequency domain resource includes: sending or receiving the first signal on the second frequency domain resource, wherein the first signal and the signal carried on the first frequency domain resource correspond to the same spatial domain processing parameters.

[0009] In this method, a first communication device indicates to a second communication device via first information which frequency domain resources on the second frequency domain resources correspond to the same spatial processing parameters, and transmits signals on these frequency domain resources corresponding to the same spatial processing parameters, so that the second communication device can learn which frequency domain resources correspond to the same spatial processing parameters, thereby enabling joint perception based on the signals on the frequency domain resources with the same spatial processing parameters. Because joint perception based on the signals on the frequency domain resources with the same spatial processing parameters can improve perception accuracy and resolution, this method helps improve perception accuracy and resolution.

[0010] From another perspective, the first communication device indicates to the second communication device through the first information which frequency domain resources on the second frequency domain resources correspond to the same spatial domain processing parameters, and sends signals on these frequency domain resources corresponding to the corresponding spatial domain processing parameters, providing technical support or the possibility of implementation for high-precision perception and high-resolution perception.

[0011] In this method, a first communication device indicates to a second communication device, via first information, which frequency domain resources on the second frequency domain resources correspond to the same spatial processing parameters, so that the second communication device can determine which frequency domain resources should correspond to the same spatial processing parameters when transmitting signals on the second frequency domain resources. Furthermore, the first communication device receives signals on these frequency domain resources corresponding to the corresponding spatial processing parameters, thereby receiving signals on frequency domain resources corresponding to the same spatial processing parameters. In this way, when the first communication device performs joint perception based on the signals on these frequency domain resources with the same spatial processing parameters, perception accuracy and resolution can be improved. Therefore, this method helps improve perception accuracy and resolution.

[0012] From another perspective, the first communication device indicates to the second communication device through the first information which frequency domain resources on the second frequency domain resources correspond to the same spatial domain processing parameters, and receives signals on these frequency domain resources corresponding to the corresponding spatial domain processing parameters, providing technical support or the possibility of implementation for high-precision perception and high-resolution perception.

[0013] In some possible implementations, the method further includes: sending second information, where the second information indicates a second frequency domain resource, that is, the second frequency domain resource is a resource configured by the first communication device for the second communication device through the indication information.

[0014] In some possible implementations, the second frequency domain resource may be a predetermined, pre-specified, or predefined frequency domain resource. In a second aspect, the present application provides a communication method, which is applied to a second communication device. The method includes: receiving first information indicating a first frequency domain resource, the first frequency domain resource corresponding to the same spatial processing parameter; and receiving or sending a first signal on the first frequency domain resource.

[0015] In this method, after the second communication device learns which frequency domain resources correspond to the same spatial domain processing parameters, it can, when perception is required, perform joint perception based on the signals on these frequency domain resources corresponding to the same spatial domain processing parameters, thereby improving perception accuracy and resolution. From another perspective, the second communication device receives the first information and, based on the signals on the frequency domain resources indicated by the first information, provides technical support for high-precision and high-resolution perception.

[0016] In this method, the second communication device learns which frequency domain resources correspond to the same spatial domain processing parameters and transmits signals using the same spatial domain processing parameters on these frequency domain resources. This allows the first communication device, when perception is required, to perform joint perception based on the signals on these frequency domain resources corresponding to the same spatial domain processing parameters, thereby improving perception accuracy and resolution. From another perspective, the second communication device receives the first information and transmits signals using the same spatial domain processing parameters on the frequency domain resources indicated by the first information, providing technical support for high-precision and high-resolution perception.

[0017] In some possible implementations of the second aspect, the first frequency domain resource belongs to a second frequency domain resource. Receiving or sending a first signal on the first frequency domain resource includes: receiving or sending a first signal on the second frequency domain resource, wherein signals in the first signal carried on the first frequency domain resource correspond to the same spatial domain processing parameters.

[0018] In this method, after the second communication device learns which frequency domain resources in the second frequency domain resources correspond to the same spatial domain processing parameters, it can, when perception is required, perform joint perception based on the signals on these frequency domain resources corresponding to the same spatial domain processing parameters, thereby improving perception accuracy and resolution. From another perspective, the second communication device receives the first information and, based on the signals on the frequency domain resources indicated by the first information, provides technical support for high-precision and high-resolution perception.

[0019] In this method, the second communication device learns which frequency domain resources in the second frequency domain resources correspond to the same spatial domain processing parameters and uses the same spatial domain processing parameters to send signals on these frequency domain resources. This allows the first communication device to perform joint perception based on the signals on these frequency domain resources corresponding to the same spatial domain processing parameters when perception is required, thereby improving perception accuracy and perception resolution. From another perspective, the second communication device receives the first information and sends signals using the same spatial domain processing parameters on the frequency domain resources indicated by the first information, providing technical support for high-precision and high-resolution perception.

[0020] In some possible implementations of the second aspect, the method further includes: receiving second information, where the second information indicates a second frequency domain resource, that is, the second frequency domain resource is a resource configured by the first communication device for the second communication device through the indication information.

[0021] In some possible implementations, the second frequency domain resource may be a predetermined, pre-specified, or pre-defined frequency domain resource.

[0022] In the methods of the first aspect and the second aspect, the first frequency domain resources corresponding to the same spatial domain processing parameters may include: the first frequency domain resources corresponding to the same beam, or the first frequency domain resources corresponding to the same precoding.

[0023] In some possible implementations, when receiving a first signal on a second frequency domain resource, the method includes: performing sensing based on the signal received on the first frequency domain resource.

[0024] In this implementation, the second communication device receives signals on frequency domain resources with the same spatial domain processing parameters, and can achieve joint perception by processing the received signals.

[0025] In some possible implementations, the first frequency domain resource belongs to the second frequency domain resource, including: the second frequency domain resource includes N frequency domain resource units, N is a positive integer, and the first frequency domain resource includes M frequency domain resource units in the second frequency domain resource, M is a positive integer less than or equal to N.

[0026] Optionally, the frequency domain resource unit is a resource group, or the frequency domain resource unit is a resource block.

[0027] In some possible implementations, the first information indicates a first frequency domain resource, including: the first information includes a first field, the first field includes N bits, the N bits correspond one-to-one to the N frequency domain resource units, the values ​​of the M bits of the N bits that correspond one-to-one to the M frequency domain resource units are first values, and the values ​​of other bits of the N bits other than the M bits are second values.

[0028] In some possible implementations, the first frequency domain resource includes S frequency domain resource sets, each of the S frequency domain resource sets includes at least one frequency domain resource unit, and the frequency domain resource units included in each frequency domain resource set are continuous in the frequency domain, and S is a positive integer.

[0029] When the first frequency domain resource includes S frequency domain resource sets, in some implementations, the first information indicates the first frequency domain resource, including: the first information includes S sub-information, the S sub-information corresponds one-to-one to the S frequency domain resource sets, and each sub-information in the S sub-information indicates a frequency domain resource unit in the corresponding frequency domain resource set.

[0030] As an example, each sub-information indicates a frequency domain resource unit in a corresponding frequency domain resource set, including: each sub-information includes the number of each frequency domain resource unit in the corresponding frequency domain resource set. This indication method can most flexibly indicate each frequency domain resource set.

[0031] As another example, each sub-information indicates a frequency domain resource unit in a corresponding frequency domain resource set, including: each sub-information includes at least two of the following information: the number of the starting frequency domain resource unit in the corresponding frequency domain resource set, the number of frequency domain resource units, or the number of the ending frequency domain resource unit. This indication method can achieve a compromise between indication flexibility and indication information overhead.

[0032] For example, each sub-information includes the number of the starting frequency domain resource unit in the corresponding frequency domain resource set and the number of frequency domain resource units in the corresponding frequency domain resource set.

[0033] For another example, each sub-information includes the number of the starting frequency domain resource in the corresponding frequency domain resource set and the number of the ending frequency domain resource in the corresponding frequency domain resource set.

[0034] Each sub-information includes the number of the ending frequency domain resource unit in the corresponding frequency domain resource set and the number of frequency domain resource units in the corresponding frequency domain resource set.

[0035] In some possible implementations, the first information and the second information are carried in the same indication information. For example, the first information and the second information are carried in the same downlink control information (DCI) or the same radio resource control (RRC) signaling. Carrying the first information and the second information in the same indication information can reduce the time delay for the two indication information to take effect.

[0036] In some possible implementations, the first information and the second information are carried in different indication information. In this implementation, the indication method of the first information and the second information is more flexible.

[0037] In one implementation, the first information and the second information are carried in different types of indication information. For example, the first information is carried in DCI and the second information is carried in RRC signaling; or, the first information is carried in RRC signaling and the second information is carried in DCI. This implementation allows network devices to retain implementation freedom and reduces timing constraints on the network devices sending indication information.

[0038] In another implementation where the first information and the second information are carried in different indication messages, the first information and the second information are carried in the same type of indication message, but they are not carried in the same indication message. For example, the first information is carried in a first DCI and the second information is carried in a second DCI; or the first information is carried in a first RRC signaling and the second information is carried in a second RRC signaling. This implementation can reserve implementation freedom for network devices and reduce the timing constraints on the network devices sending indication information.

It should be understood that each module or unit can implement the corresponding function by executing a computer program.

In the embodiments of the present application, only the device for implementing the functions of the network device is used as an example to illustrate, and does not constitute a limitation on the solutions of the embodiments of the present application.

[0073] To facilitate understanding of the communication method provided in the embodiments of the present application, the system architecture and application scenarios of the communication method provided in the embodiments of the present application are described below. It is understood that the system architecture and application scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions provided in the embodiments of the present application.

[0074] Figure 1 FIG. 1 is a schematic diagram of the architecture of the communication system 1000 used in the embodiment of the present application. Figure 1 As shown, the communication system includes a network device 110 and at least one terminal device (such as Figure 1 120a-120g in FIG). While communicating, the network devices and terminal devices in this communication system can also sense objects that do not have communication capabilities. These sensed targets include, but are not limited to, mobile targets such as vehicles, low-altitude drones, and pedestrians, as well as stationary objects in the environment, such as buildings and the ground.

[0075] Figure 1 The dashed line represents perception, and the solid line represents communication. The technical principles of perception differ somewhat from those of communication. Communication involves the transmitter modulating information onto radio waves and transmitting them to the receiver, which then demodulates the signal carried on the radio waves to retrieve the information. Perception, on the other hand, requires the transmitter to send radio waves in a specific direction. When these waves strike the target surface, they reflect back, which the receiver then receives and processes to obtain information such as the target's location, velocity, and type.

[0076] Perception can generally be divided into two modes: single-station perception and dual-station perception. Figure 2 The figure is a schematic diagram of two perception modes. The vehicle is the perceived target, and the arrow in the solid line points to the receiving end of the perception signal.

[0077] Figure 2 The perception mode shown, where Figure 2 (a) and (b) in the figure show single-station sensing. In single-station sensing, the transmitter and receiver of the sensing signal are the same device. That is, the sensing station must both send the sensing signal and receive the signal reflected by the sensing signal on the target surface. Therefore, the single-station sensing mode is also called the self-transmitting and self-receiving mode. Figure 2 (c) to (f) in the figure show dual-station sensing. In dual-station sensing, the transmitter and receiver of the sensing signal are two different devices. That is to say, after sensing station A sends the sensing signal, the signal reflected by the target surface is received by sensing station B. Therefore, the dual-station sensing mode is also called A transmit B receive mode.

[0078] In the embodiments of this application, beamforming refers to a special directional transmission or reception effect created by a transmitter or receiver of a network device or terminal device using an antenna array, much like a flashlight focusing light in a single direction to form a beam. Transmitting and receiving signals in the form of beamforming can effectively increase the signal's transmission distance.

[0079] Furthermore, the beam may be a wide beam, a narrow beam, or other types of beams. The beam forming technology may be a beamforming technology or other technologies. The beamforming technology may specifically be a digital beamforming technology, an analog beamforming technology, or a hybrid digital / analog beamforming technology.

[0080] A beam is a communication resource. Beams correspond to resources, and different beams can send the same or different information. In other words, different resources can send the same or different information. During data transmission, beam information is indicated by its corresponding resource. For example, a network device indicates a transmission configuration indication-state (TCI-state) through the TCI field in the downlink control information (DCI). The terminal device determines the beam to use for the data corresponding to the reference resource based on the reference resource contained in the TCI-state.

[0081] Multiple beams with the same or similar communication characteristics can be considered as a single beam. A beam corresponds to one or more antenna ports and is used to transmit data channels, control channels, and sounding signals. The one or more antenna ports corresponding to a beam can also be considered as an antenna port set. The beam used to transmit signals can be called a transmission beam (Tx beam), and can be called a spatial domain transmission filter or spatial transmission parameter; the beam used to receive signals can be called a reception beam (Rx beam), and can be called a spatial domain receive filter or spatial receive parameter.

[0082] The transmit beam may refer to the distribution of signal strength in different directions in space after the signal is transmitted by the antenna, and the receive beam may refer to the distribution of signal strength in different directions in space of the wireless signal received from the antenna.

[0083] Beams can be categorized as the transmit and receive beams of network devices, and the transmit and receive beams of terminal devices. A network device's transmit beam describes the device's transmit-side beamforming information, while a network device's receive beam describes the device's receive-side beamforming information. A terminal device's transmit beam describes the device's transmit-side beamforming information, while a terminal device's receive beam describes the device's receive-side beamforming information. In other words, beams can be used to describe beamforming information.

[0084] Optionally, the beam may also correspond to a spatial filter (or spatial domain filter) or a spatial domain transmission filter.

[0085] Among them, the receiving beam can be equivalent to a spatial transmission filter, a spatial domain transmission filter, a spatial domain receiving filter, and a spatial receiving filter; the transmitting beam can be equivalent to a spatial domain filter, a spatial domain transmission filter, a spatial domain transmitting filter, and a spatial transmitting filter. The information of spatial related parameters can be equivalent to a spatial filter (spatial domain transmission / receive filter). Optionally, the spatial filter generally includes a spatial transmitting filter and / or a spatial receiving filter. The spatial filter can also be referred to as a spatial domain transmitting filter, a spatial domain receiving filter, a spatial transmission filter, a spatial domain transmission filter, etc. Among them, the receiving beam on the terminal device side and the transmitting beam on the network device side can be a downlink spatial filter, and the transmitting beam on the terminal device side and the receiving beam on the network device side can be an uplink spatial filter.

[0086] For precoding, in a multi-antenna system, for a transmitter with a antennas and a receiver with b antennas, the channel model can be expressed as:

[0087] r=Hs+n0;

[0088] Where r is the received signal vector after passing through the channel; s is the transmitted signal vector at the transmitter; H is the b×a-order channel coefficient matrix for the channel; and n0 is the additive noise vector. It should be noted that for a=1 and b=1, meaning both the transmitter and receiver have a single antenna, H can also represent a 1×1 channel coefficient matrix.

[0089] In precoding, the transmitter can optimize the spatial characteristics of the transmitted signal vector s based on the channel coefficient matrix H. This allows the spatial distribution of the transmitted signal vector s to match the channel coefficient matrix H. This effectively reduces the reliance on the receiver algorithm and simplifies the receiver algorithm. Precoding can effectively improve system performance.

[0090] Precoding can be done using either linear or nonlinear methods. Due to complexity and other factors, only linear precoding is generally considered in current wireless communication systems. After precoding, the channel model of the MIMO signal can be expressed as:

[0091] r=HWs+n0;

[0092] Where W is the precoding matrix.

[0093] In a multi-user MIMO (MU-MIMO) system, the receiver cannot estimate the channel for signals sent to other devices. Therefore, transmitter precoding can effectively suppress multi-user interference. Therefore, it is beneficial for the system if the transmitter knows the channel coefficient matrix and uses appropriate precoding to process it.

[0094] In addition, in a precoding scheme, the precoding matrix W and the channel coefficient matrix H jointly determine the equivalent channel coefficient matrix (e.g., H·W), which in turn determines channel characteristics. Furthermore, in some cases, the precoding matrix W can be derived from the channel coefficient matrix H. For example, the precoding matrix W can be a matrix obtained by a transformation of the channel coefficient matrix H.

[0095] Considering that precoding and beamforming are similar in technical principles, the embodiments of the present application uniformly use beam to describe precoding and beamforming, respectively.

[0096] In an embodiment of the present application, precoding or beamforming is performed in the frequency domain with resource groups (RGs) as the granularity, wherein a resource group consists of at least two resource blocks (RBs). The power in the frequency domain in an RG is equal, and for different RGs in the frequency domain, independent precoding or beamforming is used, that is, different RGs have different beams.

[0097] Figure 3 This is a schematic diagram illustrating the correspondence between resource groups and beams in an embodiment of the present application. Resource blocks numbered #1 and #2 in the frequency domain form a resource group, using beam 1. Resource blocks numbered #3 and #4 form a resource group, using beam 2. Resource blocks numbered #5 and #6 form a resource group, using beam 3. Beam 1, beam 2, and beam 3 can be the same or different.

[0098] The transmitting end may use the same beam to send the perception signal on multiple frequency domain resources, and the receiving end may receive the perception signal and perform perception on these multiple frequency domain resources using the same beam.

[0099] However, for signal beamforming schemes that use resource groups as the granularity, even if the beams on multiple resource groups are the same, the receiver cannot know that the beams of the signals on different resource groups are the same, and thus cannot jointly perceive the signals of different resource groups, resulting in low perception accuracy.

[0100] To this end, the present application provides a new technical solution, in which a communication terminal sends information to a communication peer to indicate whether the spatial processing parameters corresponding to the frequency domain resources are the same, or in other words, a communication terminal indicates to the communication peer which frequency domain resources correspond to the same spatial processing parameters, so that the communication peer can know which frequency domain resources use the same spatial processing parameters, so that the communication peer can use the same spatial processing parameters on these frequency domain resources to send signals or perform joint perception based on the signals on these frequency domain resources, thereby improving perception accuracy. The spatial processing parameters may include beams or precoding.

[0101] The communication method proposed in this application will be introduced below in conjunction with specific embodiments. Figure 4 This is a schematic flow chart of a communication method provided in one embodiment of the present application. Figure 4 As shown, the method may include S410 and S420.

[0102] S410: A first communication device sends first information and second information to a second communication device, where the first information indicates a first frequency domain resource, and the second information indicates a second frequency domain resource, the first frequency domain resource belonging to the second frequency domain resource, and the first frequency domain resource corresponds to the same spatial domain processing parameter. Accordingly, the second communication device receives the first information and the second information.

[0103] In this embodiment, the first communication device may be a network device or a terminal device. Figure 2 The sending end of the signal shown can be either a network device or a terminal device.

[0104] In this embodiment, the second communication device may be a network device or a terminal device. Figure 2 The receiving end of the signal shown can be either a network device or a terminal device.

[0105] In this embodiment, the first communication device sends first information and second information to the second communication device, the first information indicates the first frequency domain resources, the second information indicates the second frequency domain resources, the first frequency domain resources belong to the second frequency domain resources, and the first frequency domain resources correspond to the same spatial domain processing parameters. It can be understood that: the first communication device indicates to the second communication device which frequency domain resources in the second frequency domain resources use the same spatial domain processing parameters, and these frequency domain resources that use the same spatial domain processing parameters are called first frequency domain resources.

[0106] The first frequency domain resources corresponding to the same spatial domain processing parameters may include: the first frequency domain resources corresponding to the same beam, or the first frequency domain resources corresponding to the same precoding.

[0107] In the embodiments of the present application, because a beam is a communication resource and different beams can be considered different resources, there is a one-to-one correspondence between frequency domain resources and beams. That is, one frequency domain resource corresponds to one beam, and different frequency domain resources correspond to multiple beams. These multiple beams can be completely identical, partially identical, or completely different. The term "identical beam" refers to a beam with identical or similar communication characteristics.

[0108] In the embodiment of the present application, precoding is a method for optimizing the spatial characteristics of a signal. Completely identical, partially identical, or completely different precoding methods can be used on different frequency domain resources. Therefore, the first frequency domain resource corresponding to the same precoding here refers to precoding using the same method.

[0109] In some implementations, that the first frequency domain resource belongs to the second frequency domain resource may include: the first frequency domain resource includes all or part of the frequency domain resources in the second frequency domain resource.

[0110] In this embodiment, the first frequency domain resource belongs to the second frequency domain resource, including: the second frequency domain resource includes N frequency domain resource units, N is a positive integer, and the first frequency domain resource includes M frequency domain resource units in the second frequency domain resource, M is a positive integer less than or equal to N.

[0111] It is understood that when the first frequency domain resource includes M frequency domain resource units, the first frequency domain resource corresponding to the same spatial domain processing parameter may include: the M frequency domain resource units corresponding to the same spatial domain processing parameter. For example, the M frequency domain resource units correspond to the same beam, or the M frequency domain resource units correspond to the same precoding.

[0112] In this embodiment, the frequency domain resource unit may be an RG or an RB.

[0113] As an example, a signal sent by a first communications device to a second communications device occupies a certain carrier bandwidth in the frequency domain, but not the entire carrier bandwidth. The carrier bandwidth includes P resource blocks, where P is a positive integer greater than 2. In other words, the second frequency domain resources are the frequency domain resources occupied by the signal sent by the first communications device to the second communications device, that is, a subset of the resource blocks in the carrier bandwidth. For example, the first communications device is a network device, and the second communications device is a terminal.

[0114] As an example, the second frequency domain resources are frequency domain resources occupied by downlink signals scheduled by the network device, which may be one or more frequency domain resource blocks or one or more frequency domain resource groups.

[0115] In some implementations of this embodiment, the first information and the second information are carried in the same indication information. For example, the first information and the second information are carried in the same DCI or the same radio resource control (RRC) signaling.

[0116] In some possible implementations, the first information and the second information are carried in different indication information. In this implementation, the indication method of the first information and the second information is more flexible.

[0117] In one implementation manner in which the first information and the second information are carried in different indication information, the first information and the second information are carried in different types of indication information. For example, the first information is carried in DCI and the second information is carried in RRC signaling; or the first information is carried in RRC signaling and the second information is carried in DCI.

[0118] In another implementation manner in which the first information and the second information are carried in different indication information, the first information and the second information are carried in the same type of indication information, but the first information and the second information are not carried in the same indication information. For example, the first information is carried in a first DCI and the second information is carried in a second DCI; or the first information is carried in a first RRC signaling and the second information is carried in a second RRC signaling.

[0119] When the first information and the second information are carried in different indication information, in some implementations, the second information may be sent before the first information.

[0120] Optionally, the second frequency domain resource in this embodiment may be a predetermined, pre-specified, or pre-defined frequency domain resource.

[0121] In this embodiment, the first frequency domain resource may be a frequency domain resource used for sensing, that is, the signal transmitted on the first frequency domain resource may be used for sensing. It is understood that the signal transmitted on the first frequency domain resource may also be used for communication.

[0122] In some implementations, a bitmap may be used to indicate which resources in the second frequency domain resources belong to the first frequency domain resources, or in other words, a bitmap may be used to indicate which resources in the second frequency domain resources are included in the first frequency domain resources. This indication method is simple and convenient.

[0123] The first information indicates the first frequency domain resource. In some implementations, the first information includes a first field, and the first field carries the first information. For example, the first field is a bitmap field, and the bitmap field includes N bits, and the N bits correspond one-to-one to N frequency domain resource units (i.e., resource blocks) in the second frequency domain resource.

[0124] It can be understood that the N bits correspond one-to-one to the N frequency domain resource units, which means that each bit is used to indicate whether the corresponding frequency domain resource unit belongs to the first frequency domain resource.

[0125] Among these N bits, the frequency domain resource units corresponding to the bits with the same bit value and the specified value belong to the first frequency domain resources, or in other words, the frequency domain resource units corresponding to the bits with the same bit value and the specified value correspond to the same beam or precoding.

[0126] As an example, the first value is "1" and the second value is "0". That is, the frequency domain resource unit corresponding to the bit with the bit value of "1" in the bitmap belongs to the first frequency domain resource, and the frequency domain resource unit corresponding to the bit with the bit value of "0" in the bitmap does not belong to the first frequency domain resource.

[0127] As another example, the first value is "0" and the second value is "1." That is, the frequency domain resource unit corresponding to the bit with the bit value "1" in the bitmap belongs to the first frequency domain resource, and the frequency domain resource unit corresponding to the bit with the bit value "0" in the bitmap does not belong to the first frequency domain resource.

[0128] For example, for a 20MHz system bandwidth, the number of resource blocks corresponding to a 15kHz subcarrier spacing is 52, and the bitmap field is 52 bits. Among them, the resource blocks corresponding to the bits with a bit value of "1" are resource blocks that can be used for perception, and the bit value of "0" indicates that the corresponding resource blocks are not available for perception. It can be understood that for resource blocks indicated as available for perception, the second communication device can understand that these resource blocks correspond to the same beam or precoding.

[0129] In some possible implementations, the first frequency domain resource includes S frequency domain resource sets, each of the S frequency domain resource sets includes at least one frequency domain resource unit, and the frequency domain resource units included in each frequency domain resource set are continuous in the frequency domain, and S is a positive integer.

[0130] In other words, the M frequency domain resource units in the first frequency domain resource can be divided into S frequency domain resource sets, each frequency domain resource set contains at least one frequency domain resource unit, and the frequency domain resource units in each frequency domain resource set are continuous.

[0131] It can be understood that, generally, any two frequency domain resource sets in the S frequency domain resource sets do not contain the same frequency domain resource units, or in other words, each frequency domain resource unit in the M frequency domain resource units belongs to a frequency domain resource set of the S frequency domain resource sets.

[0132] The first information indicates the first frequency domain resource. In some implementations of this embodiment, the first information includes S sub-information, and these S sub-information correspond one-to-one to S frequency domain resource sets. Each sub-information in the S sub-information indicates the frequency domain resource unit in the corresponding frequency domain resource set, wherein each sub-information includes the number of each frequency domain resource unit in the corresponding frequency domain resource set.

[0133] Each sub-information indicates a frequency domain resource unit in a corresponding frequency domain resource set, which can be understood as: each sub-information is used to identify which frequency domain resource units in the second frequency domain resources belong to the frequency domain resource units in the corresponding frequency domain resource set.

[0134] When each sub-information indicates a frequency domain resource unit in a corresponding frequency domain resource set, as a first example, each sub-information indicates a frequency domain resource unit in a corresponding frequency domain resource set, including: each sub-information contains the number of each frequency domain resource unit in the corresponding frequency domain resource set.

[0135] As an example, the number of the frequency domain resource unit may be the number of the frequency domain resource unit in the N frequency domain resource units.

[0136] When each sub-information includes the number of each frequency domain resource unit in the corresponding frequency domain resource set, as an example, the first information includes multiple resource indication version (RIV) fields, each RIV field indicating multiple consecutive frequency domain resource blocks. RIV can be understood as the number of multiple consecutive resource blocks.

[0137] When each sub-information indicates a frequency domain resource unit in a corresponding frequency domain resource set, as a second example, each sub-information includes at least two of the following information: the number of the starting frequency domain resource unit in the corresponding frequency domain resource set, the number of frequency domain resource units, or the number of the ending frequency domain resource unit.

[0138] In some implementations, each sub-information may include: the number of the starting frequency domain resource in the corresponding frequency domain resource set and the number of frequency domain resource units in the corresponding frequency domain resource set.

[0139] When each sub-information may include the number of the starting frequency domain resource in the corresponding frequency domain resource set and the number of frequency domain resource units in the corresponding frequency domain resource set, as an example, the first information includes multiple indication tuples, wherein each tuple includes the starting resource block number and the number of consecutive resource blocks. For example, the system bandwidth includes 52 resource blocks, and the first information includes two tuples, wherein the first tuple is {0,20}, that is, the first information indicates 20 consecutive resource blocks starting from the resource block numbered 0; the second tuple is {30,22}, then the first information indicates 22 consecutive resource blocks starting from the resource block numbered 30 as frequency domain resource blocks that can be used for perception, and the remaining unindicated resource blocks in the 52 resource blocks are frequency domain resource blocks that cannot be used for perception.

[0140] In some implementations, each sub-information may include: the number of the starting frequency domain resource in the corresponding frequency domain resource set and the number of the ending frequency domain resource in the corresponding frequency domain resource set.

[0141] When each sub-information may include the number of the starting frequency domain resource in the corresponding frequency domain resource set and the number of the ending frequency domain resource in the corresponding frequency domain resource set, as an example, the first information includes multiple indication tuples, wherein each tuple includes the starting resource block number and the ending resource block number. For example, the system bandwidth includes 52 resource blocks, and the first information includes two tuples, wherein the first tuple is {0,20}, that is, the first information indicates 21 resource blocks numbered 0 to 20; the second tuple is {30,51}, then the first information indicates that 22 resources numbered 30 to 51 are available frequency domain resource blocks, and the remaining unindicated resource blocks in the 52 resource blocks are frequency domain resource blocks that cannot be used for perception.

[0142] S420: The first communication device sends a first signal to the second communication device on the second frequency domain resource, wherein the signals in the first signal carried on the first frequency domain resource correspond to the same spatial domain processing parameters. Accordingly, the second communication device receives the first signal on the second frequency domain resource.

[0143] In this embodiment, the first communication device indicates to the second communication device which frequency domain resources (first frequency domain resources) in the second frequency domain resources correspond to the same spatial domain processing parameters, and when sending signals on the second frequency domain resources, the signals on these frequency domain resources (first frequency domain resources) correspond to the same spatial domain processing parameters, which provides technical support or possibility for the second communication device to perform joint perception based on the signals on these frequency domain resources corresponding to the same spatial domain processing parameters when perception is needed.

[0144] Optionally, this embodiment may further include S430, that is, the second communication device performs perception based on the signal carried on the first frequency domain resource.

[0145] It can be understood that after the second communication device receives the first signal on the second frequency domain resource, it can learn based on the first information that the signal carried on the first frequency domain resource corresponds to the same spatial processing parameters, or it can learn based on the first information that the signal carried on the first frequency domain resource can be used for perception, and perform joint perception based on the signal carried on the first frequency domain resource, thereby improving the perception accuracy and perception resolution performance.

[0147] S510: A first communications device sends first information and second information to a second communications device, where the first information indicates a first frequency domain resource and the second information indicates a second frequency domain resource, wherein the first frequency domain resource belongs to the second frequency domain resource and the first frequency domain resources correspond to the same spatial processing parameters. Accordingly, the second communications device receives the first information and the second information.

[0148] This step may refer to S410 and will not be described in detail here.

[0149] S520: The second communication device sends a first signal to the first communication device on the second frequency domain resource, wherein the signals in the first signal carried on the first frequency domain resource correspond to the same spatial domain processing parameters.

[0150] This step can refer to S420 and will not be described in detail here. For example, the first communication device and the second communication device in S420 can be exchanged to obtain the implementation method of S520.

[0151] In this embodiment, the first communication device indicates to the second communication device which frequency domain resources (first frequency domain resources) in the second frequency domain resources correspond to the same spatial domain processing parameters, and when receiving signals on the second frequency domain resources, makes the signals on these frequency domain resources (first frequency domain resources) correspond to the same spatial domain processing parameters, providing technical support or possibility for the first communication device to perform joint perception based on the signals on these frequency domain resources corresponding to the same spatial domain processing parameters when perception is needed.

[0152] Optionally, this embodiment may further include S530, that is, the first communication device performs perception based on the signal carried on the first frequency domain resource.

[0153] It can be understood that after the first communication device receives the first signal on the second frequency domain resource, it can learn based on the first information that the signal carried on the first frequency domain resource corresponds to the same spatial processing parameters, or it can learn based on the first information that the signal carried on the first frequency domain resource can be used for perception, and perform joint perception based on the signal carried on the first frequency domain resource, thereby improving the perception accuracy and perception resolution performance.
