[0140] In some possible implementations, the terminal device can include a wireless communication function device, such as a chip system, a chip, or a chip module. For example, the chip system can include a chip and can also include other discrete devices.

[0141] The terminal device in the embodiments of the present application is a terminal device with sensing capability, for example, a UE with sensing signal receiving and / or transceiving capability, sensing data processing capability, (partial) sensing result calculation capability, and other sensing capabilities.

[0142]

Network device

[0143] The network device is a device with transceiving function. In some schemes, the network device includes an access network device. The access network device is used to communicate with the terminal device, so that the terminal device can access the network. The access network device is also connected with the core network device to realize network interconnection.

[0144] Unless otherwise specified, the network device involved in the present application is an access network device.

[0145] Optionally, the network device can be responsible for radio resource management (RRM), quality of service (QoS) management, data compression and encryption, data transceiving, and the like on the air interface side.

[0146] Optionally, the network device can include a base station (BS) in a communication system or a device deployed in a radio access network (RAN) for providing wireless communication function, i.e., the network device can include a device in the RAN.

[0147] For example, the device in the RAN can include an evolutional node B (eNB or eNodeB) in an LTE communication system, a next generation evolved node B (ng-eNB) in an NR communication system, a next generation node B (gNB) in an NR communication system, a master node (MN) in a dual connectivity architecture, a secondary node (SN) or a second node in a dual connectivity architecture, etc., without specific limitation thereto.

[0148] Optionally, the network device can include a device with a wireless communication function for the terminal device, such as a chip system, a chip, or a chip module. For example, the chip system can include a chip, or can include other discrete devices.

For example, the network device includes a centralized unit (CU) and a distributed unit (DU), such as gNB-CU and gNB-DU. Further, in some embodiments of the present application, the network device can also include an active antenna unit (AAU). Among them, the CU implements part of the functions of the network device, and the DU implements another part of the functions of the network device. For example, the CU is responsible for processing non-real-time protocols and services, implementing the functions of the radio resource control (RRC) layer, the service data adaptation (SDAP) layer, and the packet data convergence (PDCP) layer. The DU is responsible for processing the physical layer protocol and real-time service, and implementing the functions of the radio link control (RLC) layer, the medium access control (MAC) layer, and the physical (PHY) layer. In addition, the AAU can implement part of the physical layer processing function, the radio frequency processing, and the related function of the active antenna. Since the information of the RRC layer will eventually become the information of the PHY layer, or be converted from the information of the PHY layer, under this network deployment, the high-layer signaling (such as RRC signaling) can be considered to be generated by the CU and sent by the DU, or sent by the DU and the AAU together. It can be understood that the network device can include at least one of the CU, the DU, and the AAU. In addition, the CU can be divided into a RAN device, or the CU can be divided into a core network device, which is not limited.

[0157] Optionally, the intelligent module can be a chip or a chip module.

[0158] For example, refer to Figure 1 , Figure 1 A network architecture diagram of a communication system to which embodiments of the present application are applicable is shown. As Figure 1 shown, the communication system 10 can include a network device 110 and a terminal device 120. The terminal device 120 can communicate with the network device 110 in a wireless manner.

[0159] Figure 1 The network architecture of the communication system is only an example, and the network architecture of the communication system of the embodiments of the present application is not limited thereto.

[0160] For example, the communication system 10 can further include a server or other devices.

[0161] For another example, the communication system 10 can include other network devices in addition to the network device 110, such as other access network devices in addition to the network device 110, or a core network device.

[0162] For another example, the communication system 10 can include other terminal devices in addition to the terminal device 120, and the number of terminal devices is not limited herein.

[0163] In some business scenarios, a terminal device can be required to perform sensing measurement based on a sensing reference signal, and the sensing data / result can be required to be transmitted to a network device, so as to facilitate the network device to subsequently instruct the sensing behavior of the terminal device or to perform area-level sensing information merging.

[0164] For example, as shown in Figure 2 , Figure 2 is a scenario diagram provided by an embodiment of the present application. Since the position of the UAV changes during operation, the network device needs to sense the position and speed of the UAV, but due to environmental influence, there can be some blind areas, so it is necessary to select a suitable terminal device to perform measurement based on a sensing reference signal, so as to perform sensing assistance, and the terminal device needs to report the sensing result (i.e., sensing measurement report) to the network device.

[0165] For example, as shown in Figure 2 , when the UAV moves from position 1 to position 2, there can be a position that cannot be sensed by the network device 201 and the network device 202, at which time the terminal device 204 and the terminal device 205 are required to perform measurement based on a sensing reference signal. For example, the terminal device 204 receives the sensing reference signal sent by the network device 201 and performs measurement based on the sensing reference signal, or the terminal device 204 sends the sensing reference signal and receives the echo of the sensing reference signal, and performs measurement based on the sensing reference signal, so as to assist in sensing the position and speed of the UAV, and the terminal device 204 reports the sensing result (i.e., sensing measurement report) to the network device 201. For another example, the terminal device 205 receives the sensing reference signal sent by the network device 202 and performs measurement based on the sensing reference signal, or the terminal device 205 sends the sensing reference signal and receives the echo of the sensing reference signal, and performs measurement based on the sensing reference signal, so as to assist in sensing the position and speed of the UAV, and reports the sensing result (i.e., sensing measurement report) to the network device 202. For another example, when the UAV moves from position 2 to position 3, there can be a position that cannot be sensed by the network device 202 and the network device 203, at which time the terminal device 206 is required to perform measurement based on a sensing reference signal. For example, the terminal device 206 receives the sensing reference signal sent by the network device 203 and performs measurement based on the sensing reference signal, or the terminal device 206 sends the sensing reference signal and receives the echo of the sensing reference signal, and performs measurement based on the sensing reference signal, so as to assist in sensing the position and speed of the UAV, and the terminal device 206 reports the sensing result (i.e., sensing measurement report) to the network device 202 or the network device 203. Further, the network device 201, the network device 202, and the network device 203 transmit the related information of the UAV to the data center, and the data center obtains the position, speed, and other information of the UAV after processing these data.

[0166] Based on this, in the embodiment of the present application, the network device sends the resource configuration information and the reporting configuration information to the terminal device, after the terminal device receives the resource configuration information and the reporting configuration information, the terminal device sends the sensing reference signal according to the resource configuration information and performs the measurement of the sensing reference signal, and performs the reporting of the sensing measurement report according to the reporting configuration information, so as to realize the terminal device sending the sensing reference signal and performing the measurement based on the sensing reference signal.

[0167] The following will take the interaction between the network device and the terminal device as an example to illustrate the communication method of the embodiment of the present application. The terminal device can be a chip, a chip module or a communication module, etc., and the network device can be a chip, a chip module or a communication module, etc.

[0168] Please refer to Figure 3 , Figure 3 is a flow diagram of a communication method provided by the embodiment of the present application, and specifically includes the following steps:

[0169] Step S301: The network device sends the resource configuration information and the reporting configuration information to the terminal device.

[0170] The resource configuration information is used to configure the sensing reference signal resource, and the sensing reference signal resource is used to carry the sensing reference signal. The reporting configuration information is used to configure the reporting of the sensing measurement report, and the sensing measurement report includes the measurement result obtained based on the measurement of the sensing reference signal.

[0171] Correspondingly, the terminal device receives the resource configuration information and the reporting configuration information.

[0172] Optionally, the resource configuration information and the reporting configuration information are carried by high layer signaling (such as RRC signaling, MAC signaling, etc.) / DCI.

[0173] Step S302: The terminal device sends the sensing measurement report to the network device.

[0174] Correspondingly, the network device receives the sensing measurement report.

[0175] In a possible implementation, the terminal device can perform the measurement of the sensing reference signal according to the resource configuration information, and send the sensing measurement report according to the reporting configuration information, so as to realize the terminal device performing the sensing measurement based on the sensing reference signal.

[0176] Optionally, the sensing reference signal is transmitted and received by the terminal device. For example, the terminal device can transmit the sensing reference signal according to the resource configuration information, receive the echo of the sensing reference signal, perform sensing reference signal measurement based on the echo of the sensing reference signal, and transmit the sensing measurement report according to the reporting configuration information, so as to realize the sensing measurement report of the terminal device based on the sensing reference signal.

[0177] Optionally, the sensing reference signal can also be transmitted by the network device and received by the terminal device. For example, the terminal device obtains the resource configuration information and the reporting configuration information configuration, so that the terminal device receives the sensing reference signal transmitted by the network device, performs sensing reference signal measurement based on the sensing reference signal, and transmits the sensing measurement report according to the reporting configuration information, so as to realize that the network device transmits the sensing reference signal, the terminal device receives the sensing reference signal and performs sensing measurement report based on the sensing reference signal. For example, the reporting configuration information is different from the reporting content or the reporting format in the CSI reporting configuration information. For example, the reporting configuration information in the embodiment of the present application can include angle, speed, Doppler value, or time delay value. For another example, the reporting configuration information in the embodiment of the present application reports the measurement result by 1 / 0 format, which represents the presence / absence of the target in the surrounding environment, so as to realize the reporting of the sensing result of the scanning sensing of the target in the surrounding environment.

[0178] Further, after receiving the sensing measurement report, the network device can send an instruction to the terminal device to indicate the sensing behavior of the terminal device or to perform regional level sensing information merging.

[0179] It can be seen that in the present application, the terminal device can transmit the sensing reference signal according to the resource configuration information, and then receive the echo of the sensing reference signal. The resource configuration information is used to configure the sensing reference signal resource. In this way, the terminal device can transmit the sensing reference signal, perform sensing reference signal measurement based on the sensing reference signal, and perform sensing measurement report according to the reporting configuration information, so as to realize the sensing measurement report of the sensing reference signal. Further, the present application can also realize that the network device indicates the sensing behavior of the terminal device or performs regional level sensing information merging.

[0180] In a possible implementation, when the resource configuration information includes multiple resource configurations ResourceConfig and the reporting configuration information includes multiple reporting configurations ReportConfig, a corresponding relationship between the ResourceConfig and the ReportConfig needs to be established. Optionally, the reporting configuration information is associated with the resource configuration information, so that the terminal device can know that the sensing reference signal carried by a resource set Resource set in a certain ResourceConfig needs to be reported by using the information in which ReportConfig to report the measurement obtained sensing measurement report, thereby establishing the corresponding relationship between the ResourceConfig and the ReportConfig.

[0181] The following describes a possible implementation of associating the reporting configuration information with the resource configuration information.

[0182] In an embodiment, the reporting configuration information is associated with the resource configuration information according to an indication of the resource configuration information.

[0183] In a possible implementation, the resource configuration information includes first information, and the first information is used to indicate that the resource configuration information is associated with the reporting configuration information, thereby establishing an association relationship between the resource configuration information and the reporting configuration information.

[0184] See Figure 4 , Figure 4 is a schematic diagram of resource configuration information and reporting configuration information provided by an embodiment of the present application. As shown in Figure 4 , the resource configuration information includes multiple ResourceConfig, for example, ResourceConfig0, ResourceConfig1, and ResourceConfig2, each of which includes a Resource set and associated reporting information Associated report. The reporting configuration information includes multiple ReportConfig, for example, ReportConfig0, ReportConfig1, and ReportConfig2. The Resource set is a configured sensing reference signal resource set, and one Resource set can include multiple sensing reference signal resources. The Associated report is used to indicate the association relationship between the ResourceConfig and the ReportConfig, and the Associated report can be understood as a possible implementation of the first information.

[0185] In Figure 4In the embodiment, the Associated report in the ResourceConfig0 indicates the association between the ResourceConfig0 and the ReportConfig0, and the terminal device can know that the sensing reference signal carried by the Resource set in the ResourceConfig0 needs to be reported by the sensing measurement report obtained by measuring the information in the ReportConfig0. The Associated report in the ResourceConfig1 indicates the association between the ResourceConfig1 and the ReportConfig2, and the terminal device can know that the sensing reference signal carried by the Resource set in the ResourceConfig1 needs to be reported by the sensing measurement report obtained by measuring the information in the ReportConfig2. The Associated report in the ResourceConfig2 indicates the association between the ResourceConfig2 and the ReportConfig1, and the terminal device can know that the sensing reference signal carried by the Resource set in the ResourceConfig2 needs to be reported by the sensing measurement report obtained by measuring the information in the ReportConfig1.

[0186] In another possible implementation, the reporting configuration information is contained in the resource configuration information, so that the reporting configuration information is associated with the resource configuration information, and the association between the resource configuration information and the reporting configuration information is established.

[0187] Please refer to Figure 5 , Figure 5 is another schematic diagram of the resource configuration information and the reporting configuration information provided in the embodiment of the present application.

[0188] As Figure 5 indicates, the resource configuration information includes a plurality of ResourceConfig, for example, ResourceConfig0, ResourceConfig1, and ResourceConfig2, each of which includes a Resource set and a ReportConfig. For example, the ResourceConfig0 includes a Resource set and a ReportConfig0, the ResourceConfig1 includes a Resource set and a ReportConfig2, and the ResourceConfig2 includes a Resource set and a ReportConfig1.

[0189] When the terminal device receives the resource configuration information, it can know that the sensing reference signals carried by the Resource set in the ResourceConfig0 are the sensing measurement reports that need to be reported by the related information in the ReportConfig0. The sensing reference signals carried by the Resource set in the ResourceConfig1 are the sensing measurement reports that need to be reported by the related information in the ReportConfig2. The sensing reference signals carried by the Resource set in the ResourceConfig2 are the sensing measurement reports that need to be reported by the related information in the ReportConfig1.

[0190] In the second implementation, the association between the reporting configuration information and the resource configuration information is indicated by the reporting configuration information.

[0191] In a possible implementation, the reporting configuration information includes second information, and the second information is used to indicate the association between the reporting configuration information and the resource configuration information, so as to establish the association between the resource configuration information and the reporting configuration information.

[0192] Please refer to Figure 6 , Figure 6 is another schematic diagram of the resource configuration information and the reporting configuration information provided by the embodiments of the present application. As shown in Figure 6 , the resource configuration information includes multiple ResourceConfig, for example, ResourceConfig0, ResourceConfig1, and ResourceConfig2, and each ResourceConfig includes a Resource set. The reporting configuration information includes multiple ReportConfig, for example, ReportConfig0, ReportConfig1, and ReportConfig2, and each ReportConfig includes associated resource information Associated resource. The Associated resource is used to indicate the association between the ResourceConfig and the ReportConfig, and the Associated resource can be understood as a possible implementation of the second information. Optionally, the Associated resource can reuse the CSI-ReportConfig indication or the CSI-ResourceConfigId contained in the existing CSI measurement related configuration to establish the association between the ResourceConfig and the ReportConfig.

[0193] InFigure 6 In the embodiment, the Associated resource in the ReportConfig0 indicates the association relationship between the ResourceConfig0 and the ReportConfig0, and the terminal device can know that the perception reference signal carried by the Resourceset in the ResourceConfig0 is the perception measurement report which needs to be reported by measuring the related information in the ReportConfig0. The Associated resource in the ReportConfig1 indicates the association relationship between the ResourceConfig2 and the ReportConfig1, and the terminal device can know that the perception reference signal carried by the Resourceset in the ResourceConfig2 is the perception measurement report which needs to be reported by measuring the related information in the ReportConfig1. The Associated resource in the ReportConfig2 indicates the association relationship between the ResourceConfig1 and the ReportConfig2, and the terminal device can know that the perception reference signal carried by the Resourceset in the ResourceConfig1 is the perception measurement report which needs to be reported by measuring the related information in the ReportConfig2.

[0194] The resource configuration information is specifically described below.

[0195] The resource configuration information is used to configure a sensing reference signal resource. For example, the sensing reference signal resource is used to carry a sensing reference signal, which is a reference signal used for sensing. Optionally, the sensing reference signal can be multiplexed with an existing communication reference signal, or enhanced based on modification of the existing communication reference signal, or can be a newly designed reference signal. The present application takes an uplink sensing reference signal (SRS) as an example for illustrative description. SRS is an important uplink reference signal in a communication system, and is widely used in various functions in a communication system (such as a 5G NR system). For example, for uplink channel estimation; for terminal device sounding process for channel state information (CSI) acquisition of downlink; for uplink beam management; for positioning function; for codebook-based uplink transmission, such as frequency domain scheduling and determination of Rank / precoding matrix indicator (PMI) / modulation coding scheme (MCS); for non-codebook-based uplink transmission, such as frequency domain scheduling and determination of sounding reference signal resource indicator (SRI) / MCS; and the like.

[0196] For example, the sensing reference signal resource is configured by a high-level parameter resource configuration information ResourceConfig.

[0197] For example, ResourceConfig can configure a Resource set, and the Resource set can include the most basic sensing reference signal resource (such as Resource). ResourceConfig can configure one or more Resource sets. Each Resource set can include K (K≥1) sensing reference signal resources.

[0198] For example, the network device sends ResourceConfig to the terminal device through an RRC message. ResourceConfig includes S (S≥1, and S is an integer) resource sets, and each resource set includes K (K≥1, and K is an integer) resources. The terminal device can send SRS on the K resources indicated by the network device.

[0199] In a possible implementation, the resource configuration information includes first time domain behavior information and / or resource location information. For example, the first time domain behavior information is used to configure the time domain behavior of the sensing reference signal resource. The resource location information is used to configure at least one of the time domain resource location, the frequency domain resource location, or the space domain resource location of the sensing reference signal resource.

[0200] For example, the time domain behavior of the sensing reference signal resource includes periodicity, semi-persistence, and aperiodicity. For example, the time domain behavior of the sensing reference signal resource can be indicated by a high-layer parameter (such as a resource type resourceType).

[0201] For example, for the periodic sensing reference signal resource, after the network device configures the information of the periodic sensing reference signal resource and the configuration takes effect, the terminal device sends the sensing reference signal according to the related configuration information at a certain period until the related configuration information is invalidated.

[0202] For example, for the aperiodic sensing reference signal resource, after the network device configures the information of the aperiodic sensing reference signal resource, the terminal device does not immediately send the sensing reference signal, but sends the aperiodic sensing reference signal after receiving the triggering signaling or triggering indication sent by the network device.

[0203] For example, for the semi-persistent sensing reference signal resource, after the network device configures the information of the semi-persistent sensing reference signal resource, the terminal device does not immediately send the sensing reference signal, but sends the semi-persistent sensing reference signal after receiving the activation signaling sent by the network device. For example, once the terminal device triggers the sending of the semi-persistent sensing reference signal, the terminal device periodically sends the sensing reference signal, and stops sending the sensing reference signal after receiving the deactivation signaling sent by the network device.

[0204] The reporting configuration information is described below.

[0205] The reporting configuration information is used to configure the reporting of the sensing measurement report, and the sensing measurement report includes a measurement result obtained based on the sensing reference signal.

[0206] For example, the reporting of the sensing measurement report is configured by using a high-layer parameter sensing reference signal reporting configuration information ReportConfig.

[0207] In a possible implementation, the reporting configuration information includes at least one of second time domain behavior information, first content information, or second content information. For example, the second time domain behavior information is used to configure the time domain behavior of reporting of the perception measurement report. The first content information is used to configure the measurement result required to be carried by the perception measurement report. The second content information is used to configure the reporting format of the measurement result.

[0208] For example, the second content information is used to configure the reporting of the measurement result in the format of 1 / 0, where 1 / 0 represents the presence / absence, to realize the reporting of the perception result of the scanning perception of whether the target exists in the surrounding environment. For another example, the second content information is used to configure the reporting of the measurement result in the format of the identification ID of the perception reference signal plus the time delay between the transmission and reception of the perception reference signal, to realize the reporting of the perception result of the perception of the position movement information of the target.

[0209] Optionally, the embodiment of the present application uses a physical uplink control channel (PUCCH) to carry the reporting of the perception measurement report.

[0210] Optionally, the reporting configuration information can further include the resource used for reporting of the perception measurement report, for example, a PUCCH resource table PUCCH-resourceList. For example, the network device configures the resource used for reporting of the periodic perception measurement report through the reporting configuration information.

[0211] For example, the time domain behavior of reporting of the perception measurement report includes periodicity, aperiodicity, and semi-persistent, for example, the time domain behavior of reporting of the perception measurement report can be indicated by a high-layer parameter (such as a reporting configuration type (reportConfigType)).

[0212] For example, for aperiodic reporting (that is, the time domain behavior of reporting of the perception measurement report is aperiodic), the network device further configures a trigger (for example, a high-layer parameter TriggerState and a high-layer parameter reportTriggerSize) to be used in cooperation with the request field in the DCI.

[0213] For example, for semi-persistent reporting (that is, the time domain behavior of reporting of the perception measurement report is semi-persistent), the network device further sends a MAC CE to activate the semi-persistent reporting of the perception measurement report.

[0214] As a possible implementation, the time domain behavior of the perception reference signal resource and the time domain behavior of reporting of the perception measurement report satisfy a preset rule, which is exemplarily introduced as follows.

[0215] For ease of understanding, Table 1 shows a possible preset rule. As shown in Table 1, the preset rule includes at least one of the following:

[0216] If the time domain behavior of the sensing reference signal resource is aperiodic, the time domain behavior of the reporting of the sensing measurement report is aperiodic,

[0217] If the time domain behavior of the sensing reference signal resource is semi-persistent, the time domain behavior of the reporting of the sensing measurement report is aperiodic or semi-persistent,

[0218] Or, if the time domain behavior of the sensing reference signal resource is periodic, the time domain behavior of the reporting of the sensing measurement report is one of aperiodic, semi-persistent, or periodic.

[0219] Table 1

[0220] Aperiodic reporting Semi-persistent reporting Periodic reporting Aperiodic SRS resource Support Not support Not support Semi-persistent SRS resource Support Support Not support Periodic SRS resource Support Support Support

[0221] For example, periodic reporting, i.e., the time domain behavior of the reporting of the sensing measurement report is periodic, semi-persistent reporting, i.e., the time domain behavior of the reporting of the sensing measurement report is semi-persistent, aperiodic reporting, i.e., the time domain behavior of the reporting of the sensing measurement report is aperiodic. Periodic sensing reference signal resource, i.e., the time domain behavior of the sensing reference signal resource is periodic, semi-persistent sensing reference signal resource, i.e., the time domain behavior of the sensing reference signal resource is semi-persistent, aperiodic sensing reference signal resource, i.e., the time domain behavior of the sensing reference signal resource is aperiodic.

[0222] For example, for periodic reporting, after the network device configures periodic resource configuration information (i.e., the time domain behavior of the sensing reference signal resource is configured as periodic in the resource configuration information) and periodic reporting configuration information (i.e., the time domain behavior of the reporting of the sensing measurement report is configured as periodic in the reporting configuration information) through an RRC message (or RRC signaling), it will take effect immediately. The terminal device periodically transmits the sensing reference signal according to the periodic resource configuration information and periodically transmits the sensing measurement report according to the periodic reporting configuration information, without the need for activating / triggering the transmission of the sensing reference signal and the reporting of the sensing measurement report through MAC CE / DCI.

[0223] For example, for aperiodic reporting, if the network device configures periodic resource configuration information and aperiodic reporting configuration information (i.e., the time domain behavior of the reporting of the sensing measurement report configured in the reporting configuration information is aperiodic) through an RRC message, the sensing reference signal does not need to be activated by DCI, and only the reporting of the sensing measurement report needs to be triggered by DCI. The terminal device periodically transmits the sensing reference signal according to the periodic resource configuration information, and after receiving the DCI, transmits the sensing measurement report through the resource indicated by the DCI. The sensing reference signal resource is activated by the resource configuration information of the sensing reference signal, that is, the transmission of the sensing reference signal is activated by the resource configuration information of the sensing reference signal. The DCI includes a first indication field and a second indication field, the first indication field is used to indicate the resource used for reporting the sensing measurement report, such as PUCCH resource, and the second indication field is used to indicate the first time offset, which is the time offset between the time domain position of the resource used for reporting the sensing measurement report and the time of receiving the DCI. Optionally, the time domain position of the resource used for reporting the sensing measurement report can be the position of the first symbol in the time domain of the resource used for reporting the sensing measurement report. For example, the first time offset is the offset between the position of the last symbol of receiving the DCI and the position of the first symbol in the time domain of the resource used for reporting the sensing measurement report.

[0224] It should be noted that for the DCI, the DCI can be a DCI format 0_1 / 0_2 scrambled by SP-CSI-RNTI (semi-persistent CSI RNTI), and the request field in the DCI can be associated with the corresponding trigger state (TriggerState) by setting the code point, and the TriggerState defines the associated SRS-ReportConfig, so that the aperiodic reporting associated SRS-ReportConfig can be found through the TriggerState. If the request field takes the value 0, it means that the aperiodic reporting is not required to be triggered; if the request field takes the value 1, it means that the aperiodic reporting associated with TriggerState 1 is triggered, and the like.

[0225] Exemplarily, for the non-periodic reporting, if the network device configures the semi-persistent resource configuration information and the non-periodic reporting configuration information through the RRC message, it is required to first activate the sensing reference signal resource through the MAC CE, i.e., to activate the transmission of the sensing reference signal through the MAC CE, and then to activate the reporting of the sensing measurement report through the DCI. The terminal device receives the MAC CE, starts to transmit the sensing reference signal, and after receiving the DCI, transmits the sensing measurement report through the resource indicated by the DCI. The MAC CE is used to activate the sensing reference signal resource, the DCI includes the first indication field and the second indication field, and the first indication field and the second indication field are described above.

[0226] Exemplarily, for the non-periodic reporting, if the network device configures the semi-persistent resource configuration information and the non-periodic reporting configuration information through the RRC message, it is required to first activate the sensing reference signal resource through the MAC CE, i.e., to activate the transmission of the sensing reference signal through the MAC CE, and then to activate the reporting of the sensing measurement report through the DCI. The terminal device receives the MAC CE, starts to transmit the sensing reference signal, and after receiving the DCI, transmits the sensing measurement report through the resource indicated by the DCI. The MAC CE is used to activate the sensing reference signal resource, the DCI includes the first indication field and the second indication field, and the first indication field and the second indication field are described above.

[0227] Exemplarily, for the semi-persistent reporting, if the network device configures the periodic resource configuration information and the semi-persistent reporting configuration information through the RRC message, it is not required to activate the transmission of the sensing reference signal through the first MAC CE, but only to activate the reporting of the sensing measurement report through the second MAC CE. The terminal device periodically transmits the sensing reference signal according to the periodic resource configuration information, and after receiving the second MAC CE, transmits the sensing measurement report through the resource indicated by the second MAC CE. The sensing reference signal resource is activated through the resource configuration information of the sensing reference signal, i.e., the transmission of the sensing reference signal is activated through the resource configuration information of the sensing reference signal, and the second MAC CE is also used to indicate the resource used for reporting the sensing measurement report.

[0228] For example, for semi-persistent reporting, if the network device configures semi-persistent resource configuration information and semi-persistent reporting configuration information through an RRC message, the network device can activate the sensing reference signal resource (i.e., activate the transmission of the sensing reference signal) and the reporting of the sensing measurement report through one MAC CE. The terminal device receives the MAC CE, starts to transmit the sensing reference signal, and transmits the sensing measurement report through the reporting resource indicated by the MAC CE. For example, the MAC CE includes a first field and a second field, the first field is used to activate the sensing reference signal resource, and the second field is used to indicate the resource used for reporting the sensing measurement report, for example, PUCCH resource 1.

[0229] For example, the Resource ID (equivalent to the first field described above) is included in one MAC CE, which is used to indicate the sensing reference signal resource. The MAC CE adds a 1-byte length (equivalent to the second field described above, and optionally, other byte lengths) after the Resource ID, which is used to indicate the resource used for reporting the sensing measurement report. For example, the field is "R R R R S3 S2 S1 S0", and the sensing measurement report can be carried by S0, S1, S2, and S3 in the MAC CE, so as to report the sensing measurement report. In this way, when the terminal device receives the MAC CE, it knows which sensing reference signal resource is used to transmit the sensing reference signal, and needs to receive the echo of the sensing reference signal, perform sensing measurement on the sensing reference signal, and carry the sensing measurement report through the resource used for reporting the sensing measurement report.

[0230] For example, for semi-persistent reporting, if the network device configures semi-persistent resource configuration information (i.e., the time domain behavior of the sensing reference signal resource is configured as semi-persistent in the resource configuration information) and semi-persistent reporting configuration information (i.e., the time domain behavior of the reporting of the sensing measurement report is configured as semi-persistent in the reporting configuration information) through an RRC message, the network device needs to first activate the transmission of the sensing reference signal through a first MAC CE (e.g., MAC CE1), and then activate the reporting of the sensing measurement report through a second MAC CE (i.e., MAC CE2). The terminal device receives the first MAC CE, starts to transmit the sensing reference signal, and receives the second MAC CE, and transmits the sensing measurement report through the reporting resource indicated by the second MAC CE. The first MAC CE is used to activate the sensing reference signal resource, and the second MAC CE is used to indicate the resource used for reporting the sensing measurement report, for example, PUCCH resource 1.

[0231] Optionally, the second MAC CE can distinguish whether the resource is used for reporting the perception measurement report by introducing a new field or a predefined rule.

[0232] For example, the S / C field in the second MAC CE is "R R R R S3 S2 S1 S0", which indicates that the perception measurement report can be carried by S0, S1, S2 and S3, and thus the perception measurement report is reported.

[0233] Optionally, the "R R R R S3 S2 S1 S0" in the second MAC CE is modified to "S7 S6 S5 S4 S3 S2 S1 S0", and the "S / C" field is modified to R, so as to configure multiple resources, so that the second MAC CE can indicate the resource used for reporting the perception measurement report and the resource used for reporting the CSI report. For example, the second MAC CE indicates that the CSI report can be carried by S0, S1, S2 and S3, and thus the CSI report is reported, and the second MAC CE indicates that the perception measurement report can be carried by S4, S5, S6 and S7, and thus the perception measurement report is reported.

[0234] As a possible implementation, the embodiments of the present application unify the reporting of the perception reference signal measurement and the existing CSI measurement reporting process, establish a new measurement reporting framework, so that the newly established measurement reporting framework is not only applicable to the CSI measurement reporting, but also applicable to the perception reference signal measurement reporting.

[0235] For example, please refer to Figure 7 , Figure 7 is a schematic diagram of a measurement reporting framework provided by the embodiments of the present application. As shown in Figure 7As shown, the network device can configure the reporting of the CSI report through the CSI reporting configuration information, configure the CSI-RS resource of the CSI measurement through the CSI resource configuration information, and establish the association (correspondence / mapping) relationship between the CSI-ResourceConfig and the CSI-ReportConfig through the CSI-ResourceConfigId indicated or contained in the CSI-ReportConfig. For example, the CSI-ResourceConfigId indicated or contained in the CSI-ReportConfig0 establishes the association (correspondence / mapping) relationship between the CSI-ResourceConfig0, the CSI-ResourceConfig1, and the CSI-ReportConfig0, so that the CSI carried in the CSI-Resource set in the CSI-ResourceConfig0 and the CSI-ResourceConfig1 is the CSI report that needs to be reported and measured through the related information in the CSI-ReportConfig0. For another example, the CSI-ResourceConfigId indicated or contained in the CSI-ReportConfig1 establishes the association (correspondence / mapping) relationship between the CSI-ResourceConfig1 and the CSI-ReportConfig1, so that the CSI carried in the CSI-Resource set in the CSI-ResourceConfig1 is the CSI report that needs to be reported and measured through the related information in the CSI-ReportConfig1. For another example, the CSI-ResourceConfigId indicated or contained in the CSI-ReportConfig2 establishes the association (correspondence / mapping) relationship between the CSI-ResourceConfig0 and the CSI-ReportConfig2, so that the CSI carried in the CSI-Resource set in the CSI-ResourceConfig0 is the CSI report that needs to be reported and measured through the related information in the CSI-ReportConfig2. In this way, the measurement reporting framework is applicable to the CSI measurement reporting, and the CSI measurement reporting can be achieved.

[0236] As Figure 7As shown, the network device can configure the reporting of the sensing measurement report through reporting configuration information, configure the sensing reference signal resource through resource configuration information, configure the association between the resource configuration information and the reporting configuration information through the aforementioned embodiment one or embodiment two, which will not be described herein. For example, the ReportConfig0 (for the sake of distinction, it can also be referred to as SENS-ReportConfig0 or SRS-ReportConfig0) in the reporting configuration information and the ResourceConfig0 (for the sake of distinction, it can also be referred to as SENS-ResourceConfig0 or SRS-ResourceConfig0) in the resource configuration information establish an association relationship, and the terminal device can know that the sensing reference signal carried in the Resource set (for the sake of distinction, it can also be referred to as SENS-Resource set) in the ResourceConfig0 is the sensing measurement report that needs to be reported through the related information in the ReportConfig0. In this way, the measurement reporting framework is applicable to the sensing reference signal measurement reporting, and the terminal device can send the sensing reference signal and perform measurement reporting based on the sensing reference signal.

[0237] Optionally, the configuration manner of the reporting of the sensing measurement report is the same as or different from the configuration manner of the reporting of the CSI report. For example, the ReportConfig in the reporting configuration information can be multiplexed with the CSI-ReportConfig in the CSI reporting configuration information. For another example, the ReportConfig in the reporting configuration information can be redesigned and different from the CSI-ReportConfig in the CSI reporting configuration information.

[0238] Since the reporting of the aperiodic CSI report needs to be triggered through the DCI, or the reporting of the aperiodic sensing measurement report needs to be triggered through the DCI, the network device needs to configure a trigger (Trigger) to cooperate with the DCI to trigger the reporting of the aperiodic CSI report or the reporting of the aperiodic sensing measurement report. Optionally, the reporting of the sensing measurement report and the reporting of the CSI report are triggered by the network device simultaneously or respectively. For example, the network device can trigger the CSI-ReportConfig1 in the CSI reporting configuration information and the ReportConfig0 in the reporting configuration information through the trigger simultaneously. For another example, the network device can trigger the CSI-ReportConfig1 in the CSI reporting configuration information through a first trigger and trigger the ReportConfig0 in the reporting configuration information through a second trigger.

[0239] The CSI measurement related configuration will be described below.

[0240] CSI can be channel state information used by a terminal device to feed back downlink channel quality to a network device, i.e., the terminal device can feed back downlink channel quality to the network device based on CSI, so that the network device selects a suitable modulation and coding scheme (MCS) for transmission of downlink data, reduces the block error rate (BLER) of downlink data transmission, and performs corresponding beam management, mobility management, adaptation tracking, rate matching, etc.

[0241] Among them, the CSI measurement related configuration can include CSI reporting configuration information and / or CSI resource configuration information, which can be defined by a high layer parameter CSI-MeasConfig (CSI measurement configuration information). Among them, CSI-MeasConfig can indicate (include / configure / carry) the following two high layer parameters: CSI-ResourceConfig (CSI resource configuration information) and CSI-ReportConfig (CSI reporting configuration information).

[0242] CSI-ResourceConfig can be used to configure the resources for CSI measurement, such as CSI-RS. In addition, CSI-ResourceConfig can configure CSI-Resource set.

[0243] The type of CSI-RS resource can be periodic, semi-persistent or aperiodic.

[0244] CSI-ReportConfig can be used to configure the reporting of CSI reporting.

[0245] In addition, since CSI-ReportConfig will indicate or include CSI-ResourceConfigId, through CSI-ResourceConfigId, CSI-ResourceConfig can be associated (correspond / mapped) with CSI-ReportConfig.

[0246] The report configuration type (reportConfigType) in CSI-ReportConfig can be used to indicate the reporting type of CSI reporting. Among them, CSI reporting can be transmitted through PUCCH or physical uplink shared channel (PUSCH).

[0247] In a possible implementation, since the present scheme involves reporting of the perception measurement report, the terminal device needs to report to the network device the total number of report processing units supported by the terminal device. For example, the terminal device sends terminal capability information to the network device, and the network device receives the terminal capability information. Optionally, the terminal capability information includes the total number of report processing units supported by the terminal device. For example, the terminal device can send the terminal capability information to the network device through a high-layer parameter.

[0248] For example, the total number of report processing units supported by the terminal device in the embodiment of the present application is used to represent the number of perception measurement reports and / or CSI reports that can be processed by the terminal device at the same time. For example, the total number of processing units supported by the terminal device includes the total number of report processing units supported by the terminal device for processing the perception measurement report and / or the total number of report processing units supported by the terminal device for processing the CSI report.

[0249] For example, the total number of processing units supported by the terminal device includes the total number of report processing units supported by the terminal device for processing the perception measurement report and / or the total number of report processing units supported by the terminal device for processing the CSI report.

[0250] The occupied report processing unit of the perception measurement report is described in detail as follows.

[0251] For example, the terminal device can report the number of report processing units for simultaneous perception measurement calculation supported by the terminal device through a high-layer parameter.

[0252] It should be noted that the occupied report processing unit of the perception measurement report can represent the capability of the terminal device for processing the perception measurement report. The terminal device has N1 processing units for processing the perception measurement report. It can be understood that the maximum number or total number of processing units supported by the terminal device for processing the perception measurement report is N1.

[0253] The occupied report processing unit of the CSI report is described in detail as follows.

[0254] For example, the terminal device can report the number of report processing units for simultaneous CSI calculation supported by the terminal device through a high-layer parameter.

[0255] It should be noted that the processing units occupied by the CSI report can represent the capability of the terminal device to process the CSI report. The terminal device has N2 processing units for processing the CSI report, which can be understood as the maximum or total number of processing units supported by the terminal device for processing the CSI report.

[0256] As a possible implementation, the reporting of the sensing measurement report and the reporting of the CSI report occupy the same report processing unit. That is, the report processing unit can be used for processing the sensing measurement report or the CSI report. The sum of the number of report processing units occupied by the reporting of the sensing measurement report and the number of report processing units occupied by the reporting of the CSI report is less than or equal to the total number of report processing units supported by the terminal device.

[0257] For example, the terminal capability information sent by the terminal device is that the total number of report processing units supported by the terminal device for processing the sensing measurement report and the CSI report is 4. The terminal device can have at most 4 report processing units for processing the sensing measurement report and at most 4 report processing units for processing the CSI report. The total number of report processing units for processing the sensing measurement report and the CSI report is less than or equal to 4. The network device needs to trigger the reporting within the capability range of the terminal device.

[0258] As a possible implementation, the reporting of the sensing measurement report and the reporting of the CSI report occupy different report processing units. That is, the report processing unit is used for processing the sensing measurement report or the CSI report. The number of report processing units occupied by the reporting of the sensing measurement report is less than or equal to the total number of report processing units supported by the terminal device for processing the sensing measurement report. The number of report processing units occupied by the reporting of the CSI report is less than or equal to the total number of report processing units supported by the terminal device for processing the CSI report.

[0259] For example, the terminal capability information sent by the terminal device is that the total number of report processing units supported by the terminal device for processing the sensing measurement report is 2 and the total number of report processing units supported by the terminal device for processing the CSI report is 2. The terminal device can have at most 2 report processing units for processing the sensing measurement report and at most 2 report processing units for processing the CSI report. The total number of report processing units for processing the sensing measurement report is less than or equal to 2, and the total number of report processing units for processing the CSI report is less than or equal to 2. The network device needs to trigger the reporting within the capability range of the terminal device.

[0260] Since the present application relates to the terminal device sending the sensing reference signal and performing the measurement reporting based on the sensing reference signal, the calculation time of the sensing measurement reporting needs to be redefined.

[0261] As a possible implementation, the calculation time of the sensing measurement reporting is less than the first time delay. The calculation time of the sensing measurement reporting is related to at least one of the following: the time of analyzing the DCI, the time of sending the sensing reference signal, the time of receiving the echo of the sensing reference signal, the time of processing the sensing data, or the time of calculating the sensing measurement reporting. The DCI is used to trigger the reporting of the sensing measurement reporting.

[0262] For example, when the terminal device needs to be self-initiated and self-received and perform the measurement reporting, the calculation time of the sensing measurement reporting is related to the time of sending the sensing reference signal and the time of receiving the echo of the sensing reference signal, and the maximum echo time needs to be considered, which is related to the maximum sensing distance of the sensing reference signal. Optionally, for the scenario that the terminal device is not self-initiated and self-received and performs the measurement reporting, the time of receiving the echo of the sensing reference signal does not need to be considered.

[0263] For example, the first time delay refers to the feedback time delay of the sensing measurement reporting. For example, the first time delay Z = min(n, y). Wherein, Z is the first time delay, min() is the minimum value operation, n is related to the subcarrier spacing configuration, which is configured or indicated by the network or specified by the standard protocol, and y is one or more capabilities reported by the terminal device, which is related to the time of processing the sensing data or the time of calculating the sensing measurement reporting, etc.

[0264] Optionally, if the calculation time of the sensing measurement reporting is greater than the sensing measurement reporting time delay, the terminal device can discard the sensing measurement reporting and not send the sensing measurement reporting.

[0265] The above Figure 3 A variety of possible implementation manners are provided, and the following will be described in combination with Figure 8 The possible implementation of the embodiments of the present application is exemplarily introduced. It should be understood that the logic and terms not explained in the following can be referred to the foregoing Figure 3 introduction. Alternatively, the network device can indicate the terminal device to send the sensing reference signal and perform the measurement reporting based on the sensing reference signal in an explicit manner. For example, please refer to Figure 8 , Figure 8 is a schematic diagram of another communication method provided by the embodiments of the present application, which specifically includes the following steps:

[0266] Step S801: The network device sends first indication information.

[0267] The first indication information is used to indicate, for example, that the terminal device transmits a sensing reference signal and performs measurement and reporting based on the sensing reference signal. Optionally, the first indication information can be carried by an RRC message.

[0268] Correspondingly, the terminal device receives the first indication information.

[0269] In step S802, the network device transmits resource configuration information and reporting configuration information.

[0270] Step S802 is the same as the aforementioned step S301, and reference can be made to the related description above, which will not be repeated here.

[0271] Optionally, the order of step S801 and step S802 is not limited here. For example, step S801 can be performed before step S802, step S801 can be performed after step S802, or step S801 can be performed simultaneously with step S802.

[0272] In step S803, the terminal device transmits a sensing measurement report to the network device.

[0273] Step S803 is the same as the aforementioned step S302, and reference can be made to the related description above, which will not be repeated here.

[0274] Optionally, the first indication information is associated with the resource configuration information and the reporting configuration information. Optionally, the first indication information can be included in the resource configuration information or the reporting configuration information.

[0275] For example, the first indication information is associated with the resource configuration information, and the first indication information is associated with the reporting configuration information. Therefore, after the terminal device receives the first indication information, the resource configuration information and the reporting configuration information, the terminal device can transmit a sensing reference signal according to the resource configuration information, receive a back echo of the sensing reference signal, perform measurement of the sensing reference signal based on the back echo of the sensing reference signal, perform reporting of a sensing measurement report according to the reporting configuration information, thereby realizing that the terminal device transmits a sensing reference signal and performs measurement and reporting based on the sensing reference signal.

[0276] For example, if the terminal device does not receive the first indication information within a first time period, the terminal device receives a sensing reference signal, resource configuration information and reporting configuration information transmitted by the network device, performs measurement and reporting based on the sensing reference signal, and transmits a sensing measurement report to the network device. The first time period can be a pre-set time period, which can be flexibly set according to the use scenario.

[0277] It can be seen that, in the present application, the network device can indicate the terminal device to send the sensing reference signal and report the measurement based on the sensing reference signal through the first indication information, so that the terminal device can send the sensing reference signal according to the resource configuration information sent by the network device, and then receive the echo of the sensing reference signal. In this way, the terminal device can perform the measurement of the sensing reference signal based on the sensing reference signal, and then send the sensing measurement report according to the reporting configuration information, so as to realize the sensing measurement report of the sensing reference signal.

[0278] As a possible implementation, the network device can also implicitly indicate the terminal device to send the sensing reference signal and report the measurement based on the sensing reference signal. For example, after the terminal device receives the resource configuration information and the reporting configuration information, the terminal device obtains the association relationship between the resource configuration information and the reporting configuration information, and the terminal device can know that the sensing reference signal carried by the resource set in a certain ResourceConfig needs to be reported by the sensing measurement report obtained by the measurement through the related information in a ReportConfig, so that the terminal device needs to send the sensing reference signal and report the measurement based on the sensing reference signal.

[0279] For example, the terminal device does not need to receive the explicit first indication information, but only needs to receive the resource configuration information and the reporting configuration information, and the association relationship between the resource configuration information and the reporting configuration information. For example, the terminal device receives the reporting configuration information associated with or contained in the resource configuration information. When the terminal device receives the resource configuration information, the terminal device knows that the sensing reference signal carried by the sensing reference signal resource in the resource configuration information needs to be sent, needs to receive the echo and perform the sensing measurement, and needs to send the sensing measurement report obtained by the measurement through the related information in the reporting configuration information.
