Description

Technical Field

[0001] The present application relates to the field of communication technology, and more specifically, to a communication method and a communication device. Background Art

[0002] In the process of the fifth generation mobile communication system (5G) evolving into 5G-Advanced (5G-A), communication and perception integration technology is considered to be one of the key technologies that can expand the business capabilities of mobile communication networks. This technology aims to integrate wireless communication and perception functions into the same system, and build the ability to detect, track and image targets by utilizing the various propagation characteristics of wireless signals, so that communication and perception capabilities can be integrated into one network to achieve harmonious coexistence and even mutual benefit.

[0003] In the perception scenario, the access network equipment sends perception signals based on the configured perception resources. However, the requirements of the perception service may change. For example, there are usually two perception modes in the perception scenario based on the service requirements: detection mode and tracking mode. The detection mode is to perform all-round perception of the entire perception range, while the tracking mode is to detect specific targets in certain specific areas.

[0004] Therefore, there is an urgent need for a communication method that can adapt to changes in perception service requirements and improve perception performance. Summary of the invention

[0005] The present application provides a communication method and a communication device, which can adapt to changes in perception service requirements and improve system perception capabilities.

[0006] In a first aspect, a communication method is provided, which can be executed by an access network device, or by a chip or circuit configured in the access network device, or by a logic module or software that can implement all or part of the functions of the access network device. This application does not limit this.

[0007] The method includes: sending first indication information, the first indication information is used to indicate N first resources, the N first resources belong to M first resources; sending a perception signal, the perception signal is carried by the N first resources, wherein N and M are positive integers, and N is less than or equal to M.

[0008] In the present application, the M first resources can be used to implement other functions such as positioning, and can also be used for perception.

[0009] In the present application, the M first resources may be perception resources corresponding to the first perception service demand, and the N first resources may be perception resources corresponding to the second perception service demand.

[0010] For example, the first perceived service requirement may correspond to a detection mode, and the second perceived service requirement may correspond to a tracking mode.

[0011] In a perception scenario, the service requirements of the perception service may change, and the perception resources used by the access network device may also change accordingly. In this technical solution, the access network device can indicate N first resources to the terminal device, and send a perception signal to the terminal device based on the N first resources. This allows the terminal device to receive the perception signal based on the perception resources (N first resources) indicated by the access network device. When the perception requirements used by the access network device change, for example, when switching from detection mode to tracking mode, the perception resources in the tracking mode can be dynamically indicated to the terminal device, so that the terminal device can select a suitable beam for reception under the current perception service. This improves perception performance.

[0012] In combination with the first aspect, in certain implementations of the first aspect, the N first resources are any N first resources among the M first resources; or, the N first resources are N first resources among the M first resources whose first resource indexes range from 0 to N-1; or, the N first resources are N first resources among the M first resources whose first resource indexes range from MN to M-1; or, the N first resources are N first resources among the M first resources whose first resource indexes range from 0 to m-1 and whose first resource indexes range from M-(Nm) to M-1, where m is a positive integer, and m is greater than 0 and m is less than N; or, the N first resources are N first resources among the M first resources whose first resource indexes are continuous; or, the N first resources are composed of first resources in L first resource groups, the first resources in the L first resource groups belong to the M first resources, and the first resource indexes in each of the L first resource groups are continuous.

[0013] In this technical solution, the N first resources can be continuous resources among the M first resources, or can be discontinuous resources among the M first resources. When the resource indexes are continuous, the indication overhead is small, which facilitates the reservation of continuous resources and implementation. When the resource indexes are discontinuous, the indication method is more flexible and adaptable to more scenarios.

[0014] It should be understood that when indicating N consecutive perception resources, the resource index is determined according to the order of the time domain resource positions indicated by the specific resource, and the beam index is a consecutive number from the smallest to the largest scanning angle or from the largest to the smallest. If the arrangement of both is unordered, they can be indicated by a bit map.

[0015] In combination with the first aspect, in some implementations of the first aspect, the first indication information is used to indicate indexes of the N first resources.

[0016] In combination with the first aspect, in certain implementations of the first aspect, the first indication information includes the index of the N first resources; or, the first indication information includes the value of N; or, the first indication information includes at least two of the values ​​of N, the value of m, or the value of Nm; or, the first indication information includes the minimum value of the index of the first resource among the N first resources, the maximum value of the index of the first resource, or at least two of the values ​​of N; or, the first indication information includes the value of L and the minimum value of the first resource index in each first resource group, the maximum value of the first resource index, or at least two of the values ​​of the number of first resources in the first resource group.

[0017] In this technical solution, the first indication information can indicate N first resources in different ways. The indication ways are flexible and applicable to a variety of scenarios.

[0018] In combination with the first aspect, in some implementations of the first aspect, the method also includes sending second indication information, where the second indication information is used to indicate the M first resources.

[0019] In combination with the first aspect, in some implementations of the first aspect, the method also includes sending third indication information, where the third indication information is used to indicate an index of a reference signal associated with at least one first resource among the N first resources.

[0020] In this technical solution, the association relationship between at least one of the N first resources and the beam may change. The access network device dynamically indicates the changed association relationship to the UE through the index of the reference signal, so that the UE can select a suitable beam for reception when the perception demand changes, thereby improving the perception performance and achieving flexible indication with low indication overhead.

[0021] In combination with the first aspect, in some implementations of the first aspect, the first indication information is carried in a media access control control element or downlink control information.

[0022] In combination with the first aspect, in some implementations of the first aspect, the perception signal is at least one of a positioning reference signal, a phase tracking reference signal, a sounding reference signal, a demodulation reference signal, and a channel state information reference signal.

[0023] In this technical solution, the perception signal can reuse the existing reference signal, with small protocol changes, low implementation complexity and stronger feasibility.

[0024] In a second aspect, a communication method is provided, which can be executed by a terminal device, or by a chip or circuit configured in the terminal device, or by a logic module or software that can implement all or part of the functions of the terminal device. This application does not limit this.

[0026] In the present application, the M first resources can be used to implement other functions such as positioning, and can also be used for perception.

[0027] In the present application, the M first resources may be perception resources corresponding to the first perception service demand, and the N first resources may be perception resources corresponding to the second perception service demand.

[0028] For example, the first perceived service requirement may correspond to a detection mode, and the second perceived service requirement may correspond to a tracking mode.

[0029] In the perception scenario, the business requirements of the perception service may change, and the perception resources used by the access network device may also need to change. In this technical solution, the terminal device can receive M first resources and N first resources sent by the access network device, and receive the perception signal sent by the access network device based on the N first resources. When the perception resources used by the access network device change, for example, when switching from the detection mode to the tracking mode, the perception resources in the tracking mode can be dynamically indicated to the terminal device, so that the terminal device can select the appropriate perception resources for reception under the current perception service, the indication is flexible, and the indication overhead can be saved.

[0031] In this technical solution, the N first resources can be continuous resources among the M first resources, or can be discontinuous resources among the M first resources. When the resource indexes are continuous, the indication overhead is small, which facilitates the reservation of continuous resources and implementation. When the resource indexes are discontinuous, the indication method is more flexible and adaptable to more scenarios.

[0032] In combination with the second aspect, in some implementations of the second aspect, the first indication information indicates indexes of the N first resources.

[0033] In combination with the second aspect, in certain implementations of the second aspect, the first indication information includes the index of the N first resources; or the first indication information includes the value of N; or the first indication information includes at least two of the values ​​of N, m, or Nm; or the first indication information includes the minimum value of the index of the first resource among the N first resources, the maximum value of the index of the first resource, or at least two of the values ​​of N; or the first indication information includes the value of L and the minimum value of the first resource index in each first resource group, the maximum value of the first resource index, or at least two of the values ​​of the number of first resources in the first resource group.

[0034] In this technical solution, the terminal device can determine N first resources based on different indication methods of the first indication information. The indication method is flexible and applicable to a variety of scenarios.

[0035] In combination with the second aspect, in certain implementations of the second aspect, third indication information is received; and an index of a reference signal associated with at least one of the N first resources is determined based on the third indication information.

[0036] In this technical solution, the association relationship between perception-related resources and beams changes. The terminal device determines the beam associated with the perception resource based on the index of the reference signal associated with the perception resource indicated by the access network device, so that the UE can select appropriate perception resources for reception in the tracking state, realizing flexible indication with low indication overhead.

The network device 110 can be a network device in cell #1, or the network device 110 can serve a terminal device (such as terminal device 120) in cell #1.

[0096] It should be noted that a cell can be understood as an area within the coverage range of wireless signals of network equipment.

[0097] It should be understood that Figure 1 The simplified schematic diagram is provided for ease of understanding. The wireless communication system 100 may also include other network devices or other terminal devices. Figure 1 The embodiments of the present application can be applied to any communication scenario in which a transmitting device and a receiving device communicate with each other.

[0098] In order to facilitate understanding of the embodiments of the present application, the terms involved in the embodiments of the present application are briefly explained below.

[0099] 1. Perception: In the field of communications, perception refers to obtaining information about the surrounding environment through a perception network, such as target positioning, target imaging, target detection, and target tracking. This perception information can be used to optimize and improve the communication system, such as avoiding obstacles and improving communication quality. Perception can also be used for channel modeling and signal analysis of wireless communication systems to better understand and optimize communication performance.

[0100] 2. Self-perception: In this application, self-perception refers to the perception measurement of the perception target by receiving the perception signal emitted by itself. For example, in wireless communication, self-perception can include the perception of the wireless channel, the perception of the transmission power, the perception of the signal quality, etc. For example, the transmitter transmits a perception signal, and the perception signal is received by the transmitter after being reflected by the perception target. The transmitter can obtain the distance of the perception target based on the transmission time and reception time of the perception signal. Self-perception technology has applications in many fields, such as smart transportation, smart cities, smart homes, etc. Self-perception can also be called a single-station perception mode. From the perspective of the perception signal process, the perception station must both send a perception signal and receive the signal reflected by the perception signal on the target surface. Therefore, the single-station perception mode is also called a self-transmitting and self-receiving mode.

[0101] 3. Perception with separate transceiver: In this application, perception with separate transceiver refers to performing the two functions of receiving and sending independently. Perception with separate transceiver can achieve better signal reception and transmission effects, and can also reduce system complexity and improve system stability. For example, a perception system with separate transceiver includes two parts: a transmitter and a receiver. The transmitter is responsible for transmitting a perception signal, which is received by the receiver after being reflected by the perception target. The receiver processes the perception signal to obtain information about the perception target. Perception technology with separate transceiver is used in many fields, such as wireless communication, satellite communication, radar, etc. This technology can improve the transmission efficiency and reliability of the communication system, and can also reduce the complexity and cost of the system. Perception with separate transceiver can also be called a dual-station perception mode. From the perspective of the perception signal process, the transmitter and receiver of the perception signal are two different devices. From the perspective of the perception signal process, after the perception site A sends the perception signal, the signal reflected on the target surface is received by the perception site B. Therefore, the dual-station perception mode is also called the A send B receive mode.

[0102] It can be understood that in a single-station perception scenario, the access network device can send and receive signals by itself, or the terminal device can send and receive signals by itself. In a dual-station perception scenario, the access network device A can send and the access network device B can receive signals, the access network device can send and the UE can receive signals, the UE can send and the access network device can receive signals, or UE#1 can send and the access network device can receive signals.

[0103] Figure 2 It is a schematic diagram of a perception scenario applicable to an embodiment of the present application.

[0104] in, Figure 2 (a) shows a sensing scenario in which access network device A transmits and receives the sensing signal on its own. Access network device A transmits a sensing signal, and access network device A receives a reflected signal generated when the sensing signal encounters a target in the environment, thereby sensing information such as the position and speed of the target. Figure 2 (b) shows a perception scenario where access network device A sends and receives signals from access network device B. Access network device A transmits a perception signal, and access network device B receives a reflection signal generated when the perception signal encounters a target in the environment, and then access network device B perceives information such as the position and speed of the target. Figure 2 (c) shows the perception scenario of access network device A sending and receiving by terminal device. Access network device A transmits a perception signal, and the terminal device receives a reflection signal generated by the perception signal encountering a target in the environment, and then the terminal device perceives information such as the position and speed of the target.

[0105] in, Figure 2 (d) shows a UE self-transmitting and self-receiving perception scenario, where UE#1 transmits a perception signal, and UE#1 receives a reflected signal generated when the perception signal encounters a target in the environment, thereby perceiving information such as the position and speed of the target. Figure 2 (e) shows the perception scenario of UE#1 sending and receiving access network devices. UE#1 transmits a perception signal, and access network device B receives a reflection signal generated by the perception signal encountering a target in the environment, and then access network device B perceives the target's position, speed and other information. Figure 2 (f) shows the perception scenario of UE#1 sending and UE#2 receiving. UE#1 transmits a perception signal, and UE#2 receives a reflection signal generated by the perception signal encountering a target in the environment, and then UE#2 perceives the target's position, speed and other information.

[0106] The above perception scenarios are merely illustrative and do not limit the embodiments of the present application.

[0107] In this application, the sensed target includes various tangible objects in the environment that can reflect electromagnetic waves, such as mountains, forests, or buildings, and can also include movable objects such as vehicles, drones, pedestrians, and terminal devices. The sensed target can also be called a target, a detected target, a sensed object, a detected object, or a sensed device, etc., which is not limited in the embodiments of this application.

[0108] In the perception scenario, the business requirements of the perception service may change. For example, the perception area changes. In this case, it is necessary to perceive the perception target in a specific area. For another example, the perception target moves. In this case, it is necessary to perceive the target area of ​​the perception target. For another example, the perception target changes. In this case, it is necessary to perceive a specific perception target. When the business requirements of the perception service change, the perception resources used by the access network equipment may also change accordingly. In other words, different perception resources can be used to execute perception services with different requirements. Therefore, changes in perception requirements may also be reflected in changes in perception resources.

[0109] In the present application, the access network device may determine the perception resources to be used based on the perception requirements. After the perception requirements change, the perception resources used by the access network device may also change based on the current perception requirements. In other words, the access network device may use different perception resources for different perception requirements. Changes in perception requirements can be reflected as changes in the perception area or changes in the perception target. For example, the perception requirement is to perform all-round perception of the target area. At this time, the access network device can use all configured perception resources. When the perception requirement changes to perception of a part of the target area, the access network device can use part of the configured perception resources.

[0110] In this application, the change of the sensing requirement can also be reflected as the change of the sensing mode, and different sensing modes correspond to different sensing resources. In other words, different sensing modes correspond to different sensing requirements, and different sensing requirements can use different sensing resources.

[0111] Exemplarily, in the embodiment of the present application, the switching of the sensing mode is explained by taking the switching between the detection mode and the tracking mode as an example. Among them, the detection mode corresponds to the sensing demand before the change, and the tracking mode corresponds to the sensing demand after the change. The embodiment of the present application does not limit this.

[0112] In this application, the detection mode is to perform all-round perception of the entire perception range, while the tracking mode is to detect specific targets in certain specific areas.

[0113] It should be understood that the detection mode and tracking mode described below are merely exemplary illustrations of changes in business requirements. In addition, the embodiments of the present application do not limit the terms of the detection mode and tracking mode.

[0114] Figure 3 A schematic diagram of a detection mode and a tracking mode is shown. This scenario takes the access network device's self-transmission and self-reception as an example. During the detection process, the access network device will use the initially configured four beams to scan and complete the full range detection of the detection area. For example, Figure 3, beam #1, beam #2, beam #3 and beam #4 are shown in FIG. Further, when switching to the tracking mode, the access network device selects some beams, such as Figure 3 As shown in the figure, beam #2 and beam #3 are only scanned during the tracking process to enhance the perception in a partial area.

[0115] Among them, the access network equipment sends perception signals based on perception resources. When switching between detection mode and tracking mode, due to the different requirements of the two processes, the beams used by the access network equipment and the perception resources associated with them may also change. At this time, it is necessary to dynamically indicate the perception resources to the UE to enable the UE to select the appropriate receiving beam according to the specified perception resources.

[0116] Exemplarily, a positioning reference signal (PRS) can be used as a perception signal. The access network device configures a PRS resource set, which is a set of PRS resources of a TRP. The access network device can use the beam associated with the PRS resource to send the PRS signal. The PRS signal supports flexible configuration in the time domain and also supports configuration of different bandwidths in the frequency domain. In the scenario where PRS resources are multiplexed for perception, the access network device can use the configured PRS resources for perception. Since the PRS resources used by the access network device will change in different perception modes, the corresponding beam information associated with the PRS resources may also change. At this time, the UE needs to be informed of the changed PRS resource information so that the UE can select the optimal receiving beam according to the PRS resources used.

[0117] In view of this, an embodiment of the present application provides a communication method, which can dynamically indicate the perception resources corresponding to the perception service demand when the perception service demand changes.

[0118] The communication method provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings. The embodiment provided by the present application can be applied to the above Figure 1 The communication system shown is not limited.

[0119] The solution of this application is described in detail below.

[0120] Figure 4 4 is a schematic flow chart of a communication method 400 provided in an embodiment of the present application. For ease of description, the method 400 is exemplarily described below by taking the interaction between an access network device and a terminal device as an example. It can be understood that the terminal device can be a component of the terminal device (such as a chip or circuit), or the access network device can also be a component of the network device (such as a chip or circuit), without limitation.

[0121] In the present application, the access network device configures M first resources to the UE, and the M first resources can be used for perception and other functions such as positioning.

[0122] Exemplarily, the M first resources may be resources configured by the access network device in the initial state. For example, the access network device may configure M PRS resources through RRC signaling, and the M PRS resources may be used to implement the positioning function and may also be used for sensing. The resource may be used to send at least one of a positioning reference signal, a phase tracking reference signal, a sounding reference signal, a demodulation reference signal, a channel state information reference signal, etc. The embodiments of the present application are not limited to this.

[0123] In the detection mode, the access network device sends a sensing signal based on the beam corresponding to the index of the reference signal associated with the M first resources; when the access network device switches to the tracking mode, the access network device can configure some or all of the M first resources to the UE. The specific method includes the following steps:

[0124] S410, the access network device sends first indication information.

[0125] The first indication information is used to indicate N first resources, where the N first resources belong to M first resources.

[0126] In a possible implementation, before sending the first indication information, the access network device sends the second indication information to the UE to indicate M first resources. The M first resources can be used to implement other functions such as positioning, and can also be used for perception. This application does not limit this.

[0127] Correspondingly, the UE receives the second indication information, determines M first resources according to the second indication information, the indexes of the reference signals associated with the M first resources correspond to different beams, and receives the perception signal based on the M first resources.

[0128] In the present application, M first resources can be understood as perception resources corresponding to the first perception service demand, and N first resources can be understood as perception resources corresponding to the second perception service demand. In other words, when the perception service demand switches from the first perception service demand to the second perception service demand, the perception resources used by the access network device need to be switched from M first resources to N first resources.

[0129] An optional understanding is that the M first resources can be understood as sensing resources for a first area, and the N first resources can be understood as sensing resources for a second area, and the second area belongs to the first area.

[0130] An optional understanding is that M first resources are used in the detection mode, and N first resources are used in the tracking mode.

[0131] In the present application, the M first resources may be indicated by using M indexes. The M indexes may start from index 0, index 1, or index 2, which is not limited in the present embodiment.

[0132] Exemplarily, in this embodiment, the indexes of the M first resources are {0, 1, 2, ..., M-2, M-1}.

[0133] In the present application, N first resources belong to M first resources. The relationship between the N first resources and the M first resources is explained as an example below.

[0134] In a possible implementation, the N first resources are any N first resources among the M first resources.

[0135] In this implementation, one approach is that the first indication information includes indexes of any N first resources among the M first resources.

[0136] In this implementation, one method is that the first indication information includes M bits, the M bits correspond to M first resources, and each bit can represent two states: the first resource corresponding to the bit belongs to the N first resources, or the first resource corresponding to the bit does not belong to the N first resources.

[0137] Table 1 below shows the state of the first resource indicated by the i-th bit among the M bits.

[0138] Table 1

[0139] The value of the i-th bit meaning 0 The i-th resource belongs to one of N resources 1 The i-th resource does not belong to one of the N resources

[0140] Among them, the i-th bit in the M bits can take a value of 0 or 1. When the i-th bit is 0, the first resource corresponding to index i does not belong to the N first resources. When the i-th bit is 1, the first resource corresponding to index i belongs to the N first resources. The opposite is also possible.

[0141] Based on the above Table 1, a specific example is given.

[0142] Figure 5 A schematic diagram of a resource indication method is shown. When M is equal to 8, the first field includes 8 bits. If the state indicated by the 8 bits is 01100110, it means that among the 8 first resources, the first resources with indexes 1, 2, 5, and 6 are used in the tracking mode, and the first resources with indexes 0, 3, 4, and 7 are not used in the tracking mode, or in other words, they do not belong to the N first resources. Figure 5 As shown in , among the 8 first resources, the first resources with indexes of 1, 2, 5, and 6 are used in the tracking mode, that is, the first field indicates the 4 first resources with indexes of 1, 2, 5, and 6.

[0143] Table 1 and Figure 5 This is only an illustrative description and does not limit the embodiments of the present application.

[0144] In a possible implementation, the N first resources are N first resources whose first resource indexes range from 0 to N-1 among the M first resources.

[0145] An optional understanding is that the N first resources are the first N consecutive first resources among the M first resources. In other words, the N first resources are the consecutive N resources among the M first resources with indexes starting from 0, that is, the first resources with indexes {0, 1, 2, ..., N-2, N-1}.

[0146] In this implementation, the first indication information includes the value of N, where N is a positive integer less than or equal to M.

[0147] Exemplarily, the first indication information includes a first field, where the first field includes X bits. The states of the X bits may indicate the value of N.

[0148] Table 2 below provides examples of values ​​of the state indication N through X bits.

[0149] Table 2

[0150]

[0151]

[0152] When M is equal to 9, X may be 4 bits, and the 4 bits may indicate the value of N. For example, as shown in Table 2, state 0000 indicates that the value of N is 1, state 0001 indicates that the value of N is 2, state 0010 indicates that the value of N is 3, state 0011 indicates that the value of N is 4, state 0100 indicates that the value of N is 5, state 0101 indicates that the value of N is 6, state 0110 indicates that the value of N is 7, state 0111 indicates that the value of N is 8, state 1000 indicates that the value of N is 9, and states 1001, 1010, 1011, 1100, 1101, 1110, and 1111 indicate reserved states.

[0153] Based on the above Table 2, a specific example is given.

[0154] Figure 6 A schematic diagram of a resource indication method is shown. When M is equal to 9, the first field indicated by the first indication information includes 4 bits, and the state of the 4 bits is 0010, then it can be determined that the value of N is 3, that is, the first 3 first resources among the M first resources are used for tracking mode, in other words, the first resources with indexes from 0 to 2 are used for tracking mode.

[0155] Table 2 and Figure 6 This is only an illustrative description and does not limit the embodiments of the present application.

[0156] In a possible implementation, the N first resources are N first resources whose first resource indexes range from MN to M-1 among the M first resources.

[0157] An optional understanding is that the N first resources are the last N consecutive first resources among the M first resources. In other words, the N first resources are the consecutive N resources among the M first resources indexed starting from MN, that is, the first resources indexed as {MN, M-N+1,…, M-2, M-1}.

[0158] In this implementation, the first indication information includes the value of N, where N is a positive integer less than or equal to M.

[0159] Exemplarily, the first indication information includes a first field,

[0160] Table 1 below shows the state of the first resource indicated by the i-th bit among the M bits. The states of the X bits may indicate the value of N.

[0161] Table 3 below provides examples of values ​​of the X-bit state indication N.

[0162] Table 3

[0163] Value The value of N 0000 1 0001 2 0010 3 0011 4 … … 0111 8 1000 9 1001 Reserve … … 1111 Reserve

[0164] When M is equal to 9, X may be 4 bits, and the 4 bits may indicate the value of N. For example, as shown in Table 2, state 0000 indicates that the value of N is 1, state 0001 indicates that the value of N is 2, state 0010 indicates that the value of N is 3, state 0011 indicates that the value of N is 4, state 0100 indicates that the value of N is 5, state 0101 indicates that the value of N is 6, state 0110 indicates that the value of N is 7, state 0111 indicates that the value of N is 8, state 1000 indicates that the value of N is 9, and states 1001, 1010, 1011, 1100, 1101, 1110, and 1111 indicate reserved states.

[0165] Based on the above Table 3, a specific example is given.

[0166] Figure 7A schematic diagram of a resource indication method is shown. When M is equal to 9, the first field indicated by the first indication information includes 4 bits, and the state of the 4 bits is 0010, then it can be determined that the value of N is 3, that is, the last 3 first resources among the M first resources are used for tracking mode, in other words, the first resources with indexes 6 to 8 are used for tracking mode.

[0167] Table 3 and Figure 7 This is only an illustrative description and does not limit the embodiments of the present application.

[0168] In one possible implementation, the N first resources are N first resources whose first resource indexes range from 0 to m-1 and whose first resource indexes range from M-(Nm) to M-1 among the M first resources, where m is a positive integer, and m is greater than 0 and m is less than N.

[0169] An optional understanding is that the N first resources include two parts, one part is the first m first resources among the M first resources, and the other part is the last Nm first resources among the M first resources. In other words, the N first resources include resources distributed in the first part of the M first resources and resources distributed in the last part of the M first resources, that is, the first resources indexed as {0, 1, ..., m-2, m-1, M-(Nm), M-(Nm)+1, ..., M-2, M-1}.

[0170] In this implementation, the first indication information includes at least two of the values ​​of N, the values ​​of m, or the values ​​of Nm.

[0171] Exemplarily, the first indication information includes a first field and a second field, and the first field and the second field are respectively used to indicate two values ​​among the values ​​of N, the value of m, or the value of Nm, where m is a positive integer greater than 0 and less than N.

[0172] The first field or the second field includes X bits, The state of the X bits may indicate any one of the values ​​of N, m, or Nm.

[0173] Table 4 below provides examples of indicating the value of N, the value of m, or the value of Nm through the status of X bits.

[0174] Table 4

[0175] Value N / m / Nm value 000 1 001 2 010 3 011 4 … … 111 8

[0176] Wherein, when M is equal to 8, the first field or the second field may include 3 bits, and the 3 bits may indicate any one of the values ​​of N, m, or Nm. For example, as shown in Table 4, state 000 indicates that the value of N, m, or Nm is 1, state 001 indicates that the value of N, m, or Nm is 2, state 010 indicates that the value of N, m, or Nm is 3, state 011 indicates that the value of N, m, or Nm is 4, and state 111 indicates that the value of N, m, or Nm is 8.

[0177] It should be noted that the value of m or the value of Nm indicated by the first field or the second field is less than or equal to the indicated value of N.

[0178] Based on the above Table 4, a specific example is given.

[0179] Figure 8 A schematic diagram of a resource indication method is shown. When M is equal to 8, the 3 bits included in the first field indicated by the first indication information are used to indicate the value of N, and the 3 bits included in the second field indicated by the first indication information are used to indicate the value of m. The state of the first field is 101, and the state of the second field is 001, then the value of N is 6, and the value of m is 2, that is, the first 2 first resources and the last 4 first resources among the M first resources are used for tracking mode, in other words, the first resources with indexes from 0 to 1 and the first resources with indexes from 4 to 7 are used for tracking mode.

[0180] Table 4 and Figure 8 This is only an illustrative description and does not limit the embodiments of the present application.

[0181] In a possible implementation, the N first resources are N first resources with consecutive first resource indexes among the M first resources.

[0182] An optional understanding is that the N first resources are N consecutive first resources among the M first resources. In other words, the N first resources are N consecutive resources starting from any index among the M first resources.

[0183] In this implementation, the first indication information includes a minimum value of an index of a first resource among N first resources, a maximum value of an index of the first resource, or at least two values ​​of N, where N is a positive integer less than or equal to M.

[0184] Exemplarily, the first indication information includes a first field and a second field, and the first field or the second field includes X bits. The state of the X bits may indicate a minimum value of the index of the first resource, a maximum value of the index of the first resource, or a value of N.

[0185] Table 5 below gives an example of indicating the minimum value of the index of the first resource or the maximum value of the index of the first resource through the states of X bits.

[0186] Table 5

[0187] Value The minimum value of N resource indexes / the maximum value of N resource indexes 000 0 001 1 010 2 011 3 … … 111 7

[0188] Among them, when M is equal to 8, the first field or the second field may include 3 bits, and the 3 bits may indicate the minimum value of the index of the first resource among the N first resources or the maximum value of the index of the first resource. For example, as shown in Table 5, state 000 indicates that the minimum value of the index of the first resource among the N first resources or the maximum value of the index of the first resource is 0, state 001 indicates that the minimum value of the index of the first resource among the N first resources or the maximum value of the index of the first resource is 1, state 010 indicates that the minimum value of the index of the first resource among the N first resources or the maximum value of the index of the first resource is 2, state 011 indicates that the minimum value of the index of the first resource among the N first resources or the maximum value of the index of the first resource is 3, and state 111 indicates that the minimum value of the index of the first resource among the N first resources or the maximum value of the index of the first resource is 7.

[0189] Table 6 below provides examples of values ​​of the X-bit state indication N.

[0190] Table 6

[0191] Value The value of N 000 1 001 2 010 3 011 4 … … 111 8

[0192] When M is equal to 8, the first field or the second field may include 3 bits, and the 3 bits may indicate the value of N. For example, as shown in Table 6, state 000 indicates that the value of N is 1, state 001 indicates that the value of N is 2, state 010 indicates that the value of N is 3, state 011 indicates that the value of N is 4, state 100 indicates that the value of N is 5, state 101 indicates that the value of N is 6, state 110 indicates that the value of N is 7, and state 111 indicates that the value of N is 8.

[0193] It should also be noted that the maximum value of the index of the first resource indicated by the first indication information cannot be smaller than the minimum value, and the maximum value and minimum value of the index of the indicated first resource can be equal, in which case N is equal to 1.

[0194] Based on the above Table 5, a specific example is given.

[0195] Fig. 9A schematic diagram of a resource indication method is shown. When M is equal to 8, the 3 bits included in the first field indicated by the first indication information are used to indicate the minimum value of the index of the first resource, and the 3 bits included in the second field indicated by the first indication information are used to indicate the maximum value of the index of the first resource. The state of the first field is 001, and the state of the second field is 101. The minimum value of the index of the first resource is 1, and the maximum value of the index of the first resource is 4. Then N is equal to 3, that is, 3 first resources among the M first resources are used for tracking mode. In other words, the first resources with indexes of 2 to 4 are used for tracking mode.

[0196] Table 5, Table 6 and Fig. 9 This is only an illustrative description and does not limit the embodiments of the present application.

[0197] In this solution, the indicated N sensing resources are N continuous resources, the indication overhead is small, and it is convenient to reserve continuous resources.

[0198] It should be understood that when indicating N consecutive perception resources, the resource index is determined according to the order of the time domain resource positions indicated by the specific resource. At the same time, the beam index is a consecutive number from the smallest to the largest scanning angle or from the largest to the smallest. If the arrangement of both is unordered, it can be indicated by a bit map. The method of indication by bit map is more flexible and can adapt to more scenarios.

[0199] In one possible implementation, the N first resources are composed of first resources in L first resource groups, the first resources in the L first resource groups belong to the M first resources, and the first resource index in each of the L first resource groups is continuous.

[0200] An optional understanding is that in the tracking mode, multiple targets can be tracked. Assuming that L targets need to be tracked, one or multiple consecutive resources can be configured from the M first resources to form a resource group for each tracking target, that is, the L first resource groups correspond to the L targets respectively, and the first resources in the L first resource groups constitute N first resources. In other words, the N first resources are multiple groups of first resources among the M first resources, wherein each group of first resources may include one first resource or multiple consecutive first resources, and each group of first resources is used to sense one target.

[0201] In this implementation, the first indication information is used to indicate the value of L and at least two of the minimum value of the first resource index in each first resource group, the maximum value of the first resource index, or the value of the number of first resources in the first resource group.

[0202] Exemplarily, the first indication information includes a first field and a second field, and the number of bits contained in the first field or the second field can be determined according to the L first resource groups to be indicated and the value of M. The first field or the second field can be composed of L identical fields, each field is used to indicate the minimum value of the first resource index in the corresponding first resource group, the maximum value of the first resource index, or one of the values ​​of N, and the L fields are respectively used to indicate the minimum value of the first resource index in the L resources, the maximum value of the first resource index, or one of the values ​​of N.

[0203] Tables 7 and 8 below provide examples of indicating the minimum value and the maximum value of the first resource index in the corresponding resource group through fields, respectively.

[0207] Value meaning 010100 The maximum value of the first resource group index is 2, and the maximum value of the second resource group index is 4 011101 The maximum value of the first resource group index is 3, and the maximum value of the second resource group index is 5 100110 The maximum value of the first resource group index is 4, and the maximum value of the second resource group index is 6 100111 The maximum value of the first resource group index is 4, and the maximum value of the second resource group index is 7 … …

[0208] When M is equal to 8, assuming that two first resource groups need to be indicated, each field includes The relevant indication of the sth first resource group occupies bits, that is, the first 3 bits indicate the first resource group, and the last 3 bits indicate the second resource group. For example, as shown in Table 10, the state of the first field indicates the minimum value of the index of the two resource groups. Specifically, the state 000010 indicates that the minimum value of the index of the first resource of the first resource group is 0, and the minimum value of the index of the first resource of the second resource group is 2; the state 001011 indicates that the minimum value of the index of the first resource of the first resource group is 1, and the minimum value of the index of the first resource of the second resource group is 3; the state 010100 indicates that the minimum value of the index of the first resource of the first resource group is 2, and the minimum value of the index of the first resource of the second resource group is 4; the state 011110 indicates that the minimum value of the index of the first resource of the first resource group is 3, and the minimum value of the index of the first resource of the second resource group is 6; for another example, as shown in Table 11, the state of the second field indicates the maximum value of the index of the two resource groups. Specifically, state 010100 indicates that the maximum value of the index of the first resource of the first resource group is 2, and the maximum value of the index of the first resource of the second resource group is 4; state 011101 indicates that the maximum value of the index of the first resource of the first resource group is 3, and the maximum value of the index of the first resource of the second resource group is 5; state 100110 indicates that the maximum value of the index of the first resource of the first resource group is 4, and the maximum value of the index of the first resource of the second resource group is 6; state 100111 indicates that the maximum value of the index of the first resource of the first resource group is 4, and the maximum value of the index of the first resource of the second resource group is 7.

[0209] It should be noted that the minimum value of the index of the first resource of the resource group indicated by the first field must be less than or equal to the maximum value of the index of the first resource of the resource group indicated by the second field.

[0210] Based on the above Tables 7 and 8, a specific example is given.

[0211] Fig.10A schematic diagram of a resource indication method is shown. When M is equal to 8 and L is equal to 2, the 6 bits included in the first field indicated by the first indication information are used to indicate the minimum value of the index of the first resource of the first resource group and the minimum value of the index of the first resource of the second resource group, and the 6 bits included in the second field indicated by the first indication information are used to indicate the maximum value of the index of the first resource of the second resource group and the maximum value of the index of the first resource of the second resource group. If the state of the first field is 000100, then the minimum value of the index of the first resource of the first resource group is 0, and the minimum value of the index of the first resource of the second resource group is 4. If the state of the second field is 010101, then the maximum value of the index of the first resource of the first resource group is 2, and the minimum value of the index of the first resource of the second resource group is 5, that is, the index of the first resource included in the first resource group is {0, 1, 2}, and the index of the first resource included in the second resource group is {4, 5}. In other words, the first resources with indexes 0 to 2 and the first resources with indexes 4 to 5 are used to track two sensing targets respectively.

[0212] In a possible implementation, the first indication information includes a first field, the first field includes M bits, the M bits correspond to M first resources, and each bit can represent two states: the first resource corresponding to the bit belongs to the N first resources, or the first resource corresponding to the bit does not belong to the N first resources. The indication method is consistent with the meaning in Table 1 above. For example, when the indicated state is 11101100, assuming that state 1 indicates that the indicated resource belongs to the N selected resources, then the resource usage and Fig.10 Consistent.

[0213] In a possible implementation, the resources in the above L first resource groups constitute N first resources, and the first indication information may include L fields, each field being used to indicate the first resource included in the corresponding resource group.

[0214] For example, the first indication information includes L fields, and each field includes the index of the first resource in the corresponding resource group.

[0215] Tables 7, 8 and Fig.10 This is only an illustrative description and does not limit the embodiments of the present application.

[0216] In a possible implementation, the first indication information is used to indicate indexes of N first resources.

[0217] In this implementation manner, the first indication information indicates indexes of N first resources among the M first resources.

[0218] Exemplarily, the first indication information includes a first field, which is composed of N identical fields, each field is used to indicate the index of N resources, then the field includes bits.

[0219] The following is given in Table 12 bits indicate N instances of the first resource.

[0220] Table 9

[0221] Value meaning 000010 The first resource has an index of 0, and the second resource has an index of For 2 001011 The first resource index is 1, the second resource index is For 3 010100 The first resource index is 2, the second resource index is For 4 011110 The first resource index is 3, the second resource index is For 6 … …

[0222] Among them, when M=8, N=2, this field has a total of 6 bits, and the first three bits and the last three bits indicate the indexes of the two first resources respectively. As shown in Table 12 above, when the 6-bit state is 000010, the first resource index is 0, and the second resource index is 2, when the 6-bit state is 001011, the first resource index is 1, and the second resource index is 3, when the 6-bit state is 010100, the first resource index is 2, and the second resource index is 4, when the 6-bit state is 011110, the first resource index is 3, and the second resource index is 6.

[0223] Based on the above Table 9, a specific example is given.

[0224] Fig.11 A schematic diagram of a resource indication method is shown. When M=8 and N=2, the first field includes 6 bits. If the state indicated by the 6 bits is 001011, it means that among the 8 first resources, the first resources with indexes 0 and 2 are used for tracking mode, such as Fig.11 As shown in , among the 8 first resources, the first resources with indexes 0 and 2 are used for tracking mode, that is, the first field indicates the 2 first resources with indexes 0 and 2.

[0225] Table 9 and Fig.11 This is only an illustrative description and does not limit the embodiments of the present application.

[0226] The above method of indicating N first resources is merely an exemplary description and is not limited to this in the embodiments of the present application.

[0227] Based on the above technical solution, when the business requirements of the perception service change, the access network equipment can dynamically indicate the corresponding perception resources to the UE, so that the UE can select appropriate resources to receive the perception signal under the current business requirements. In addition, the perception resources can be indicated in different ways to achieve flexible indication and low indication overhead.

[0228] In the present application, the association relationship between the perception resources and the beam may change, that is, during the tracking phase, the index of the reference signal associated with the N first resources may change, and the same resource will be sent through different beams (different from the initially associated beams), so it is necessary to further notify the UE of the index of the reference signal associated with the selected N resources.

[0229] It should be understood that the index of the reference signal associated with each first resource corresponds to a beam, and the access network device sends a perception signal based on the beam corresponding to the index of the reference signal associated with the first resource. When the beam associated with the first resource changes, the index of the reference signal associated with the first resource also changes. Therefore, it is necessary to send the index of the reference signal associated with at least one of the N first resources to the UE, and the UE can receive the perception signal on the corresponding beam.

[0230] In a possible implementation, the access network device sends third indication information to the UE, where the third indication information is used to indicate an index of a reference signal associated with at least one first resource among the N first resources.

[0231] Exemplarily, the third indication information includes a first field, which includes bits, where Q is an optional reference signal index.

[0232] For example, when M=8 and N=2, that is, 2 first resources are selected from 8 first resources for sending in the tracking phase, the optional reference signal index sequence length is 64, that is, Q=64. At this time, the field includes 12 bits, the first 6 bits indicate the index of the reference signal associated with the first resource of the 2 first resources, and the last 6 bits indicate the index of the reference signal associated with the second first resource of the 2 resources.

[0233] Based on the above technical solution, when the association relationship between perception-related resources and beams is changed, the terminal device determines the beam associated with the perception resource according to the index of the reference signal associated with the perception resource indicated by the access network device, so that the UE can select appropriate perception resources to receive perception signals according to the current business needs, thereby achieving flexible indication with low indication overhead.

[0234] S420, the access network device sends a perception signal.

[0235] Among them, the perception signal is carried by N first resources.

[0236] The UE receives first indication information, where the first indication information indicates N first resources.

[0237] The UE can determine N first resources based on the first indication information, and receive a first signal based on the N first resources, where the first signal is a perception signal sent by the network device.

[0238] In the present application, the UE can determine the indexes of the N first resources based on the first indication information; or determine the value of N based on the first indication information; or determine at least two of the values ​​of N, m, or Nm based on the first indication information; or determine the minimum value of the index of the first resource among the N first resources, the maximum value of the index of the first resource, or at least two of the values ​​of N based on the first indication information; or determine the value of L and the minimum value of the first resource index in each first resource group, the maximum value of the first resource index, or at least two of the values ​​of the number of first resources in the first resource group based on the first indication information.

[0239] The specific determination method can be based on the table example in the above step S410, which will not be repeated here.

[0240] In the present application, the first indication information may be carried in downlink control information (DCI) signaling or a media access control (MAC) layer control element and sent by an access network device to a UE.

[0241] In the present application, when multiplexing PRS signals for perception, after the access network device configures resources through RRC signaling, the access network device sends a PRS signal, and enters the detection mode at this time; after switching to the tracking mode, the access network device sends indication information to indicate the PRS resources used by the UE, and the access network device continues to send PRS signals for perception.

[0242] The above indication information is also applicable to the scenario of multiplexing SRS signals for perception. After the access network device configures resources through RRC signaling, the UE sends SRS signals and enters the detection mode at this time; after switching to the tracking mode, the access network device sends indication information to indicate the SRS resources used by the UE, and the UE continues to send SRS signals for perception. The specific implementation method can refer to the above step S410, which will not be repeated here.
