[0074] There are two types of time domain resource allocation methods for PDSCH: Mapping Type A and Mapping Type B. The time domain resources in these two mapping types are determined by the starting symbol position S value and the symbol length L value. Mapping Type A can allocate more time domain symbols (3 to 14), but the starting symbol position can only be the first 4 symbols of each time slot. Mapping Type A is mainly used in Enhanced Mobile Broadband (eMBB) scenarios; in Mapping Type B, the starting symbol can appear at any position in the first 13 symbols of each time slot, but the minimum symbol length can be 2, so Mapping Type B is also called Mini Slot. Mapping Type B is mainly used in Ultra-Reliable Low-Latency Communication (URLLC) scenarios.
[0075] There are two frequency domain resource allocation methods for PDSCH: Resource Allocation Type 0 and Resource Allocation Type 1. Resource Allocation Type 0 uses a bitmap to specify the location of frequency domain resource blocks (RBs), with each bit representing a resource block group (RBG). Resource Allocation Type 1 uses the same method as bandwidth part (BWP) frequency domain resource allocation, specifying the starting RB position value and the number of consecutive RBs.
[0076] Through the above-mentioned time domain resource configuration and frequency domain resource configuration, the time-frequency resource position occupied by PDSCH with RB as the granularity can be obtained. When performing PDSCH resource mapping, special attention should be paid to avoiding the following resource elements (RE) in special predetermined positions: Demodulation Reference Signal (DMRS), Channel State Information-Reference Signal (CSI-RS), Phase Tracking Reference Signal (PT-RS), Timing Reference Signal (TRS), Synchronization Signal (SS) / PBCH Physical Broadcast Channel (PBCH), Control Resource Set / Control Resource Set (CORESET), Physical Downlink Control Channel (PDCCH), etc.
[0077] Integrated communication and perception technology enables communication systems to acquire sensing capabilities, enabling them to perceive targets not already on the network. For example, sensing algorithms can be used to obtain location information (including distance and angle) between the target and the base station. To integrate this capability into mobile communication systems, base stations must transmit sensing signals simultaneously with data signals. These sensing signals may share PDSCH resources with data signals and other reference signals.
[0078] As shown in Figure 1, whether using collaborative or independent sensing, the PDSCH of the transmitting base station (base station A) needs to carry both the data signal sent to the user and the sensing signal used to detect the target. For users, if they also have sensing needs, they can use this sensing signal for sensing. If the user only has communication needs, the sensing signal is useless and should be removed before data demodulation to improve rate matching, data demodulation accuracy, and processing efficiency. Therefore, the base station should notify the user of the time-frequency location of the sensing signal at the RE granularity level and inform the user whether to avoid or remove the sensing signal during data processing. Existing solutions lack notification of the user to avoid the REs occupied by the sensing signal during PDSCH scheduling, which can lead to inaccurate rate matching and, consequently, the inability to properly demodulate the data signal.
[0079] Based on this, in various embodiments of the present disclosure, a first communication device sends first information to a second communication device, and the second communication device receives the first information sent by the first communication device; wherein the first information is used to indicate whether to avoid a first resource or whether to use a perception signal carried on the first resource, and the first resource represents the resource occupied by the perception signal configured by the first communication device. It can be seen that in the embodiments of the present disclosure, the first communication device can inform the second communication device whether to avoid the first resource or use the perception signal carried on the first resource through the first information, thereby avoiding the problem of inaccurate rate matching caused by the second communication device not eliminating the perception signal or not eliminating the resources occupied by the perception signal when the first communication device is configured with the resource occupied by the perception signal, thereby improving the accuracy and processing efficiency of the demodulated data signal.
[0080] The present disclosure will be described in further detail below with reference to the accompanying drawings and embodiments.
[0081] The present disclosure provides a resource scheduling method, which is applied to a first communication device, which can be understood as a network device or a base station, and can configure the resources occupied by the sensing signal on the PDSCH, such as RE. As shown in Figure 2, the method includes:
[0082] Step 201: Send first information to a second communication device.
[0083] The first information is used to indicate whether to avoid the first resource, or to indicate whether to use the perception signal carried on the first resource, and the first resource represents the resource occupied by the perception signal configured by the first communication device.
[0084] Here, the first communication device sends the first information to the second communication device when the resources occupied by the perception signal (first resources) are configured. The second communication device can be a terminal or a base station, and the base station can also be understood as a network device. The first information is carried in signaling, messages or control information supported by both the first communication device and the second communication device. For example, when the second communication device is a terminal, the first information can be carried in downlink control information (Downlink Control Information, DCI) or a media access control (Media Access Control, MAC) control unit (Control Element, CE). When the second communication device is a base station, the first information can be sent through Xn interface signaling.
[0085] The first resource may be an RE occupied by a sensing signal on a PDSCH. Avoiding the first resource may be understood as avoiding the first resource during rate matching and / or data demodulation. Using the sensing signal carried on the first resource may be understood as using the sensing signal carried on the first resource when performing sensing measurement and estimation.
[0086] In one embodiment, when the first communication device and the second communication device perform cooperative perception, the first information is used to indicate the use of a perception signal carried on a first resource; or
[0087] When the first communication device and / or the second communication device is in an independent perception mode, or the second communication device does not have perception capability or has no perception requirement, the first information is used to indicate avoiding or not using the first resource, or indicating not using the perception signal carried on the first resource.
[0088] Here, when a first communication device and a second communication device perform cooperative sensing, the second communication device needs to perform sensing measurement and estimation based on the sensing signal sent by the first communication device. Therefore, the first information is used to indicate the use of the sensing signal carried on the first resource, or the first information is used to indicate the use of the sensing signal carried on the first resource when performing sensing measurement and estimation, so as to receive and process the sensing signal carried on the first resource, thereby performing sensing measurement and estimation using the sensing signal. The cooperative sensing between the first communication device and the second communication device can be described as the first communication device and the second communication device being in a cooperative sensing mode.
[0089] When the first communication device and / or the second communication device is in an independent perception mode, or the second communication device does not have the perception capability or has no perception requirement, the second communication device does not need the first resource or does not need to use the perception signal carried on the first resource to perform perception measurement and estimation, or only has communication requirements. For the second communication device, the perception signal carried on the first resource is a useless signal. Therefore, the first information is used to indicate avoiding or not using the first resource, or to indicate not using the perception signal carried on the first resource, so that the second communication device can remove the first resource or perception signal before performing data demodulation and / or rate matching to improve the rate matching degree or the correctness of rate matching, thereby improving the accuracy of data demodulation and processing efficiency.
[0090] In actual application, before executing step 201, the first communication device may further configure PDSCH resources and configure resources occupied by various signals on the PDSCH in the following manner.
[0091] When a first communication device and a second communication device operate in a cooperative sensing mode (also known as a collaborative sensing mode), and the second communication device is a terminal, the first communication device obtains a channel quality indicator (CQI) measured by the second communication device and the sensing requirements of the second communication device; based on the CQI and the sensing requirements of the second communication device, the first communication device configures PDSCH resources and the resources occupied by each signal on the PDSCH, for example, respectively configuring the resources occupied by the three signals of data signal, communication reference signal, and sensing reference signal. The PDSCH resources include at least one of the time domain resources, frequency domain resources, and spatial beams of the PDSCH.
[0092] When the first communication device and the second communication device operate in a collaborative sensing mode (the first communication device and the second communication device perform collaborative sensing), and the second communication device is a base station, the first communication device obtains the CQI and the sensing capability information of the second communication device, and configures the resources of the PDSCH and the resources occupied by each signal on the PDSCH according to the sensing capability information of the second communication device, for example, respectively configuring the resources occupied by the three signals of data signal, communication reference signal, and sensing reference signal. The way in which the first communication device obtains the CQI can be measured by a terminal accessing the first communication device, or measured by the second communication device, or measured by the first communication device, which is not limited in the embodiments of the present disclosure.
[0093] When the first communication device operates in an independent sensing mode, a CQI and sensing capability information of the first communication device are obtained, and based on the CQI and the sensing capability information of the first communication device, PDSCH resources and resources occupied by various signals on the PDSCH are configured, for example, resources occupied by a data signal, a communication reference signal, and a sensing reference signal are respectively configured. The CQI is measured by the first communication device or a terminal accessing the first communication device.
[0094] An optional configuration method for the resources occupied by the signal is as follows:
[0095] First, configure the time domain resource type, starting symbol position S value, and symbol length L value of the entire PDSCH; under the corresponding time domain resource type, configure the starting position and continuous number of RBs; configure beam resources, which include the direction and shape of the spatial beam.
[0096] Secondly, configure the starting position of the RE occupied by the communication reference signal, the comb type, the symbol period, etc., where the comb type includes the comb type of the time domain and / or frequency domain. The comb type of the time domain can be understood as the time domain density, and the comb type of the frequency domain can be understood as the frequency domain density.
[0097] Then, configure the starting position of the RE occupied by the perception reference signal, the comb type, the symbol period, etc.
[0098] Finally, the remaining resources of the PDSCH are allocated to data signals.
[0099] To facilitate the second communication device to avoid the first resource or use the perception signal carried by the first resource, in one embodiment, the first information includes at least one of the following:

[0102] A second identifier, where the second identifier represents an identifier or index of a perception signal pattern configured by the first communication device.
[0103] Here, the first identifier can enable the second communication device to know whether the first resource or the perception signal needs to be removed, the first quantity can help the second communication device perform rate matching, and the second identifier can indicate which perception signal pattern the first communication device configures on the PDSCH. The perception signal pattern refers to a pattern of the perception signal, which is used to indicate which REs carry the perception signal, so that the second communication device can determine the time-frequency position of the perception signal.

[0106] The first communication device may also indicate to the second communication device the location of the RE occupied by the sensing signal, so that the second communication device can accurately avoid the RE occupied by the sensing signal. Based on this, in one embodiment, the method further includes:
[0107] Sending second information to the second communication device; wherein,
[0108] The second information is used to indicate the location of the first resource, where the first resource is based on RE granularity.
[0109] Here, when the second communication device is a terminal, the second information can be carried in the radio resource control (RRC) signaling, for example, the setting information unit (IE) carried in the RRC signaling, and the setting IE can be PDSCH-Config; when the second communication device is a base station, the second information can be carried in the Xn interface signaling, for example, the setting IE carried in the Xn interface signaling, and the setting IE can be RESOURCE STATUS RESPONSE.

[0117] In order to facilitate the second communication device to know the location of the RE occupied by the perception signal, in one embodiment, the third information includes the starting position information, the time domain density and frequency domain density of the perception signal, and the second quantity; wherein,
[0118] The starting position information is used to indicate the position of the first RE occupied by the perception signal; the second number represents the number of symbols occupied by the perception signal.
[0119] Here, the time domain density of the perception signal can be understood as the comb type of the time domain of the perception signal; the frequency domain density of the perception signal can be understood as the comb type of the frequency domain of the perception signal.
[0120] The starting position information can be represented by sensing-InitialPosition, that is, the position of the first RE occupied by the sensing signal on the PDSCH can be given by sensing-InitialPosition; the value type of sensing-InitialPosition is ENUMERATED, and the value range can be {pos0, pos1, pos2, pos3}.
[0121] The frequency domain density of the perception signal can be represented by sensing-FrequencyDensity, which is an INTEGER value in the range of (0, ..., 11). The time domain density of the perception signal can be represented by sensing-Time Density, which is an INTEGER value in the range of (0, ..., 13).
[0122] The second quantity can be represented by sensing-MaxLength, the value type is INTEGER, and the value range can be (1,…,13).
[0123] It should be noted that when the first communication device is in independent perception mode, after sending PDSCH, the first communication device can also receive the echo signal and perform perception measurement and estimation based on the echo signal; the echo signal is a signal obtained by the perception signal carried on the PDSCH after being reflected by the perception target.
[0124] Correspondingly, the embodiment of the present disclosure further provides a resource scheduling method, which is applied to a second communication device, which can be a terminal or a base station, and the base station can also be understood as a network device. As shown in Figure 3, the method includes:

[0147] It should be noted that when the first communication device and the second communication device perform collaborative perception, after the second communication device receives the PDSCH and the first information sent by the first communication device, it can also receive the echo signal and perform perception measurement and estimation based on the echo signal; the echo signal is a signal obtained by the perception signal carried on the PDSCH after being reflected by the perception target.
[0148] The present disclosure will be further described in detail below in conjunction with application examples.
[0149] Application Example 1
[0150] Application example 1 is applicable to the following application scenarios: the first communication device and the second communication device perform collaborative perception, the terminal has no perception requirement, the first communication device sends first information and second information to the second communication device, and the second information is used to indicate the position of the first resource in a specific pattern of the perception signal. The position of the first resource can be understood as the position of the RE occupied by the perception signal.
[0151] For example, the first communication device is base station A, and the second communication device includes base station B and a terminal. The resource scheduling method of application example 1 includes:
[0152] Step 1: Base station A obtains the CQI measured by the terminal accessing base station A, and obtains the sensing capability information of base station B.
[0153] Step 2: Base station A configures PDSCH resources and the resources occupied by each signal on the PDSCH according to the CQI and the sensing capability information of base station B, and indicates the PDSCH resources to the terminal and base station B.
[0154] Here, PDSCH resources include at least one of the PDSCH's time domain resources, frequency domain resources, and spatial beams. Figure 4 shows an example of PDSCH resource configuration, illustrating the REs occupied by reference signals, sensing signals, and data signals on the PDSCH. In Figure 4, the PDSCH occupies 11×12=132 REs. The grids marked with D in the PDSCH represent REs occupied by DMRS, and the number of REs occupied by DMRS on the PDSCH in Figure 4 is 24. The grids marked with P represent REs occupied by PT-RS, and the number of REs occupied by PT-RS is 5. The grids marked with T represent REs occupied by TRS, and the number of REs occupied by TRS is 6. The grids marked with CSI-RS in Figure 4 represent REs occupied by CSI-RS, and the number of REs occupied by CSI-RS is 8. The grids marked with S represent REs occupied by sensing signals, and the number of REs occupied by sensing signals on the PDSCH in Figure 4 is 22. Blank grids represent REs occupied by data signals.
[0155] Step 3: Base station A sends a physical downlink control channel (PDCCH) to the terminal, and sends PDSCH, first information, and second information to the terminal and base station B; the first information is used to indicate whether to avoid the first resource, or whether to use the perception signal carried on the first resource. The first resource represents the resource occupied by the perception signal configured by base station A; the second information is used to indicate the location of the first resource, and the first resource is granular with RE.
[0156] Here, the first information includes a first identifier, a first quantity, and a second identifier. The first identifier is used to indicate whether to avoid the first resource or whether to use the perception signal carried on the first resource; the first quantity represents the number of REs occupied by the first resource, that is, the number of REs occupied by the perception signal on the PDSCH, and the first quantity is 22. The second identifier represents the identifier or index of the perception signal pattern configured by base station A; the identifier or index of the perception signal pattern is used to indicate a specific pattern of the perception signal, that is, a specific perception signal pattern.
[0157] The second information includes at least one third information. The second information sent by base station A to the terminal may include only the third information, and the second information sent by base station A to base station B may include the third information and a third identifier. The third information includes starting position information, the time domain density and frequency domain density of the sensing signal, and a second quantity. The starting position information indicates the position of the first RE occupied by the sensing signal, and the second quantity represents the number of symbols occupied by the sensing signal.
[0158] It should be noted that since the terminal has no perception needs but only communication needs, the first information sent by base station A to the terminal is used to indicate avoiding the first resource or not using the perception signal carried on the first resource; base station B has perception needs, therefore, the first information sent by base station A to base station B is used to indicate the use of the perception signal carried on the first resource.
[0159] The first information sent by base station A to the terminal can be carried in DCI, and the second information sent by base station A to the terminal can be carried in RRC signaling. For example, base station A can add Sensing Exclusion Indicator = '1' and Sensing RE Number = 22 in DCI format 1_0 or 1_1 or 1_2. Sensing Exclusion Indicator = '1' indicates avoiding the first resource or not using the sensing signal carried on the first resource. Sensing RE Number = 22 indicates that the first number is 22. Base station A can indicate the position of the RE occupied by the sensing signal in the setting IE in the RRC signaling. The setting IE can be PDSCH-Config; the setting IE can include the following information: sensing-type 'type1', sensing-InitialPosition(4,1), sensing-FrequencyDensity 1, sensing-TimeDensity 8, and sensing-MaxLength2.
[0160] Sensing-type 'type1' indicates the sensing type is type 1, which indicates cooperative sensing or collaborative sensing. Sensing-InitialPosition(4,1) indicates that the position of the first RE occupied by the sensing signal on the PDSCH is pos0 in {pos0,pos1,pos2,pos3}. Sensing-FrequencyDensity 1 indicates that the frequency domain density of the sensing signal is one sensing signal per one RE. Sensing-TimeDensity 8 indicates that the time domain density of the sensing signal is one sensing signal per eight symbols. Sensing-MaxLength 2 indicates that the number of symbols occupied by the sensing signal is two.
[0161] Step 4: The terminal receives the PDSCH, PDCCH, first information, and second information sent by base station A. Based on the first information, the terminal determines that the terminal needs to avoid the first resource, and the number of REs for carrying perception signals that need to be avoided is 22. Based on the first information and the second information, the terminal determines a third number, where the third number represents the number of REs used to transmit data signals.
[0162] Here, the third quantity in, Indicates the number of subcarriers in a physical resource block (PRB); Indicates the number of symbols allocated to PDSCH in a time slot; Indicates the number of REs occupied by DMRS on PDSCH; Indicates the number of REs occupied by PT-RS on PDSCH; Indicates the number of REs occupied by CSI-RS on PDSCH; Indicates the number of REs occupied by TRS on PDSCH; Indicates the number of REs occupied by the sensing signal on the PDSCH.
[0163] The terminal locates the positions of the REs occupied by the sensing signal and other non-data signals indicated by the second information, removes the sensing signal based on the positions of the REs occupied by the sensing signal, and removes other non-data signals based on the positions of the REs occupied by other non-data signals; and performs rate matching and data demodulation based on the third number and the positions of the REs occupied by the data signal. Other non-data signals refer to non-data signals other than the sensing signal, including DMRS, PT-RS, CSI-RS, and TRS. The third number is used for rate matching, and the positions of the REs occupied by the data signal are used for data demodulation.
[0164] Step 5: Base station B receives the PDSCH, the first information, and the second information sent by base station A; determines, based on the first information, that base station B needs to use the perception signal carried on the first resource; based on the second information, receives the echo signal of the perception signal carried on the first resource of the PDSCH, and performs perception measurement and estimation based on the received echo signal.
[0165] Application Example 2
[0166] The application scenario applicable to Application Example 2 is: the first communication device performs independent perception, and the first communication device sends first information and second information to the second communication device, where the second information is used to indicate the position of the first resource in all possible patterns of the perception signal. The position of the first resource can be understood as the position of the RE occupied by the perception signal.
[0167] The following description takes the first communication device as base station A and the second communication device as a terminal as an example. The resource scheduling method of application example 2 includes:
[0168] Step 1: Base station A obtains the CQI measured by the terminal and obtains the sensing capability information of base station A.
[0169] Step 2: Base station A configures PDSCH resources and resources occupied by various signals on the PDSCH according to the CQI and the sensing capability information of base station A, and indicates the PDSCH resources to the terminal.
[0170] Here, PDSCH resources include at least one of the PDSCH's time domain resources, frequency domain resources, and spatial beams. Figure 5 shows an example of PDSCH resource configuration, illustrating the REs occupied by reference signals, sensing signals, and data signals on the PDSCH. In Figure 5, the PDSCH occupies 11×12=132 REs. The grids marked with D in the PDSCH represent REs occupied by DMRS, and the number of REs occupied by DMRS on the PDSCH in Figure 5 is 24. The grids marked with P represent REs occupied by PT-RS, and the number of REs occupied by PT-RS is 5. The grids marked with T represent REs occupied by TRS, and the number of REs occupied by TRS is 6. The grids marked with CSI-RS in Figure 5 represent REs occupied by CSI-RS, and the number of REs occupied by CSI-RS is 8. The grids marked with S represent REs occupied by sensing signals, and the number of REs occupied by sensing signals on the PDSCH in Figure 5 is 12. Blank grids represent REs occupied by data signals.
[0171] Step 3: Base station A sends PDCCH, PDSCH, first information and second information to the terminal; the first information is used to indicate whether to avoid the first resource, or whether to use the perception signal carried on the first resource, and the first resource represents the resource occupied by the perception signal configured by base station A; the second information is used to indicate the location of the first resource, and the first resource is in RE granularity.
[0172] Here, the first information includes a first identifier, a first quantity, and a second identifier. The first identifier is used to indicate whether to avoid the first resource or whether to use the perception signal carried on the first resource. The first quantity represents the number of REs occupied by the first resource, that is, the number of REs occupied by the perception signal on the PDSCH, and the first quantity is 12. The second identifier represents the identifier or index of the perception signal pattern configured by base station A.
[0173] The second information includes a third identifier, N third information and N second identifiers; the third identifier is used to indicate that the perception mode is collaborative perception; the second identifier and the third information have a corresponding relationship; the third information represents the location information of the first resource; the second identifier represents the identifier or index of the perception signal pattern configured by base station A; N is a positive integer.
[0174] Since the terminal has no perception requirements but only communication requirements, the first information sent by base station A to the terminal is used to instruct it to avoid the first resource or not use the perception signal carried on the first resource. The first information can be carried in DCI, and the second information can be carried in RRC signaling.
[0175] For example, base station A adds Sensing Exclusion Indicator = '1', Sensing RE Number = 12, and Sensing Pattern ID = 'pattern2' in DCI format 1_0, 1_1, or 1_2. Sensing RE Number = 12 indicates that the first number is 12; Sensing Pattern ID = 'pattern2' indicates that the index or identifier of the sensing signal pattern configured by base station A is pattern2.
[0176] Base station A can indicate all possible patterns of the sensing signal and the locations of the REs occupied by the sensing signal in a configuration IE in RRC signaling. There are two possible patterns for the sensing signal: pattern 1 and pattern 2. Pattern 1 is the pattern of the sensing signal shown in Figure 4, and pattern 2 is the pattern of the sensing signal shown in Figure 5. The configuration IE can be PDSCH-Config. The configuration IE can include the following information: sensing-type 'type2', sensing-FrequencyDensity 2, and sensing-TimeDensity 6.
[0177] Sensing-type 'type2' indicates the sensing type is type 2, which indicates independent sensing. Sensing-FrequencyDensity 2 indicates that the frequency domain density of the sensing signal is one per two REs. Sensing-TimeDensity 6 indicates that the time domain density of the sensing signal is one per six symbols.
[0178] Step 4: The terminal receives the PDSCH, PDCCH, first information, and second information sent by base station A. Based on the first information, the terminal determines that the terminal needs to avoid the first resource, and the number of REs for carrying perception signals that need to be avoided is 12. Based on the first information and the second information, the terminal determines a third number, where the third number represents the number of REs used to transmit data signals.
[0179] Here, the third quantity 24-5-8-6-12=77. Among them, Indicates the number of subcarriers in a PRB; Indicates the number of symbols allocated to PDSCH in a time slot; Indicates the number of REs occupied by DMRS on PDSCH; Indicates the number of REs occupied by PT-RS on PDSCH; Indicates the number of REs occupied by CSI-RS on PDSCH; Indicates the number of REs occupied by TRS on PDSCH; Indicates the number of REs occupied by the sensing signal on the PDSCH.
[0180] Step 5: Base station A receives the echo signal of the sensing signal carried on the first resource of the PDSCH, and performs sensing measurement and estimation according to the received echo signal.
[0181] Application Example 3
[0182] Application example three is applicable to the following application scenarios: the first communication device and the second communication device perform collaborative perception, and the terminal also has perception needs. The first communication device sends first information and second information to the second communication device. The second information is used to indicate the position of the first resource in a specific pattern of the perception signal. The position of the first resource can be understood as the position of the RE occupied by the perception signal.
[0183] For example, the first communication device is base station A, and the second communication device includes base station B and a terminal. The resource scheduling method of application example three includes:
[0184] Step 1: Base station A obtains the CQI measured by the terminal accessing base station A, and obtains the sensing capability information of base station B.
[0185] Step 2: Base station A configures PDSCH resources and the resources occupied by each signal on the PDSCH according to the CQI and the sensing capability information of base station B, and indicates the PDSCH resources to the terminal and base station B.
[0186] Among them, step 2 in application example 3 is the same as step 2 in application example 1. Please refer to the relevant description above and it will not be repeated here.
[0187] Step 3: Base station A sends PDCCH to the terminal, and sends PDSCH, first information and second information to the terminal and base station B; the first information is used to indicate whether to avoid the first resource, or whether to use the perception signal carried on the first resource, and the first resource represents the resource occupied by the perception signal configured by base station A; the second information is used to indicate the location of the first resource, and the first resource is based on RE granularity.
[0188] It should be noted that the difference between step 3 in application example three and step 3 in application example one is that the terminal also has perception requirements, so the first information sent by base station A to the terminal is used to indicate the use of the perception signal carried on the first resource.
[0189] The first information sent by base station A to the terminal may be carried in DCI. For example, base station A adds Sensing Exclusion Indicator = '0' and Sensing RE Number = 22 in DCI format 1_0, 1_1 or 1_2. Sensing Exclusion Indicator = '0' indicates that the sensing signal carried on the first resource is used.
[0190] Step 4: The terminal receives the PDSCH, PDCCH, first information and second information sent by base station A; receives the echo signal of the perception signal carried on the first resource of the PDSCH according to the second information, and performs perception measurement and estimation based on the received echo signal; determines the third number and the position of the RE occupied by the data signal according to the first information and the second information, and the third number is 67; performs rate matching and data demodulation according to the third number and the position of the RE occupied by the data signal.
[0191] Step 5: Base station B receives the PDSCH, the first information, and the second information sent by base station A; determines, based on the first information, that base station B needs to use the perception signal carried on the first resource; based on the second information, receives the echo signal of the perception signal carried on the first resource of the PDSCH, and performs perception measurement and estimation based on the received echo signal.
