Description
Technical Field
[0001] The present application relates to the field of mobile communication technology, and in particular to a method and device for configuring edge link awareness resources. Background Art
[0002] The integration of communication and perception is an important technical direction for the future development of wireless communications. On the one hand, the communication module and the perception module can share the hardware for signal transmission and reception to save hardware overhead, and on the other hand, the function of perceiving the communication environment can be realized. It is an important perception scenario that the source terminal sends a perception signal to multiple surrounding destination terminals for perception measurement by multiple destination terminals, or multiple destination terminals provide measurement feedback to the source terminal to support the source terminal in obtaining channel environment information. The prior art does not support the terminal sending perception signals or reference signals to multiple terminals at the same time, and does not support periodic reference signal transmission, which limits the terminal from quickly obtaining surrounding channel environment information, and the uplink reference signal sent by the terminal to the base station cannot be used for the channel measurement between the terminal and the terminal side.

[0050] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.
[0051] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.
[0052] First embodiment:
[0053] Figure 1 The flowchart of the embodiment of the method of the present application.
[0054] The embodiment of the present invention provides a side link sensing resource configuration method, which can be used for side link channel measurement, and includes the following steps 101 to 103:
[0055] Step 101: Perception signal resource configuration information is used to configure one or more perception signal resource information.
[0056] In step 101, the perception signal resource configuration information is sent to the source terminal through the base station, that is, the source terminal obtains the perception resource configuration information from the base station side, the source terminal is a terminal that needs to send a perception signal to a destination terminal, and can select to receive and obtain the destination terminal side link feedback measurement result; the destination terminal is a terminal designated by the source terminal that needs to receive the perception signal sent by the source terminal, and can select to feed back the propagation environment measurement result based on the perception signal to the source terminal.
[0057] Preferably, the destination terminal may be one or more.
[0058] In step 101, the type of the perception signal resource configuration information includes uplink perception signal resource configuration information and / or side link perception signal resource configuration information.
[0059] The uplink perception signal resource configuration information is used to configure one or more uplink perception signal resource information, and transmit the uplink perception signal on the resource corresponding to each of the uplink perception signal resource information. The uplink perception signal resource configuration information is the full set or subset of the uplink perception signal resource configuration configured by the base station for the source terminal, that is, the base station configures one or more uplink perception signal resource sets for the source terminal, and the source terminal selects some or all of the uplink perception signal resource sets included in the uplink perception signal resource configuration information to notify the destination terminal. The uplink perception signal resource set includes one or more uplink perception signal resource information, and each uplink perception signal resource information includes the time-frequency resource location, periodicity and other information of the resource.
[0060] The side link sensing signal resource configuration information is used to configure one or more side link sensing signal resource information. The side link sensing signal resource configuration information is one or more side link sensing signal resource sets acquired by the source terminal, the side link sensing signal resource set includes one or more side link sensing signal resource information, each side link sensing signal resource information includes the time-frequency resource location, periodicity and other information of the resource, and the one or more side link sensing signal resource sets acquired by the source terminal are allocated and acquired by the base station.
[0061] In step 101, if the perception signal resource configuration information includes uplink perception signal resource configuration information, the uplink perception signal resource configuration information supports uplink and side link channel measurement; otherwise, if the perception signal resource configuration information does not include uplink perception signal resource configuration information, the uplink perception signal resource configuration information only supports uplink channel measurement.
[0062] Furthermore, the type of the uplink perception signal resource configuration information is periodic, semi-persistent or dynamic, and the uplink perception signal corresponding to the uplink perception signal resource configuration information occupies an uplink resource pool. The uplink resource pool is an uplink time-frequency resource composed of one or more uplink time-frequency resource units.
[0063] Furthermore, the type of the side link perception signal resource configuration information is periodic, semi-continuous or dynamic, and the side link perception signal corresponding to the side link perception signal resource configuration information occupies a side link resource pool based on base station scheduling. The side link resource pool is a side link time-frequency resource composed of one or more side link time-frequency resource units.
[0064] In step 101, the type and manner of the perception signal resource configuration information indicated by the base station to the source terminal, and the type and manner of the perception signal resource configuration information indicated by the source terminal to the destination terminal, have the following six corresponding combinations.
[0065] Method 1: The type of perception signal resource configuration information indicated by the base station to the source terminal is periodic, which is periodic uplink perception signal resource configuration information; the method in which the base station indicates the periodic uplink perception signal resource configuration information to the source terminal is by using downlink high-level signaling indication (Uu-RRC); the source terminal indicates to the destination terminal that the type of perception signal resource configuration information is the full set or a subset of the periodic uplink perception resource configuration information, and the method in which the source terminal indicates the perception signal resource configuration information to the destination terminal is by using side link high-level signaling (PC5-RRC); the resource pool occupied by the perception signal is an uplink resource pool.
[0066] For the above-mentioned method 1, it is necessary to further explain that when the base station configures the periodic uplink perception signal resource for the source terminal, it can indicate that the resource attribute is only uplink measurement, or supports uplink and side link measurement, and the source terminal sends the periodic uplink perception signal resource configuration information corresponding to the attribute supporting uplink and side link measurement to the destination terminal. Among them, indicating that the attribute of the periodic uplink perception signal resource is supporting uplink and side link measurement is mainly to avoid the base station from allocating uplink resources to other terminals in the time slot corresponding to the uplink perception signal resource, and reducing the conflict between the destination terminal receiving and detecting the uplink perception signal of the source terminal and the destination terminal sending the uplink resource.
[0067] The source terminal sends the side link high-layer signaling (PC5-RRC) corresponding to the configuration information to the destination terminal, and the resources carrying the PC5-RRC signaling are allocated by the base station or acquired by the destination terminal through autonomous listening.
[0068] Further optionally, if the source terminal and the destination terminal are both within the coverage of the base station, the base station obtains information about the source terminal and the destination terminal, and the base station can use a first downlink signaling (such as RRC) in a multicast manner to simultaneously indicate the periodic uplink perception signal resource configuration information to the source terminal and the destination terminal. The first downlink signaling can carry a source terminal identifier to clearly indicate the periodic uplink perception signal resource configuration for the source terminal to send the perception signal; the base station can also indicate the periodic uplink perception signal resource configuration information of the source terminal to the source terminal and the destination terminal respectively in a unicast manner.
[0069] Mode 2: The type of the perception signal resource configuration information indicated by the base station to the source terminal is semi-persistent, which is semi-persistent uplink perception signal resource configuration information; the way in which the base station indicates the perception signal resource configuration information to the source terminal is to first use downlink high-layer signaling to indicate the semi-persistent uplink perception signal resource configuration information, and then use DCI (downlink control information) or MAC CE (Media Access Control control element) to activate or deactivate; the type of the perception signal resource configuration information indicated by the source terminal to the destination terminal is a subset or a full set of the semi-persistent uplink perception signal resource configuration information indicated by the base station to the source terminal; the way in which the source terminal indicates the perception signal resource configuration information to the destination terminal is to first use side link high-layer signaling (PC5-RRC) to indicate the semi-persistent uplink perception signal resource configuration information, and then use SCI (sidelink control information) or MAC CE to activate or deactivate; the resource pool occupied by the perception signal is an uplink resource pool.
[0070] Regarding the above-mentioned method 2, it needs to be further explained that when the base station configures the semi-continuous uplink perception signal resources for the source terminal, it can indicate that the resource attribute is only for uplink measurement, or supports uplink and side link measurement. The source terminal sends the semi-continuous uplink perception signal resource configuration information corresponding to the attribute supporting uplink and side link measurement to the destination terminal.
[0071] Further optionally, when the base station activates or deactivates the semi-persistent uplink sensing resources to the source terminal, the base station may carry one or more resource set identifiers of the activated or deactivated semi-persistent uplink sensing resources (i.e., the first activation or deactivation resource set identifier) in the DCI or MAC CE to indicate which semi-persistent uplink sensing resource set is activated or deactivated, and the first activation or deactivation resource set identifier may be indicated in the signaling of the base station indicating the side link transmission resources to the source terminal. For example, when the base station indicates the side link transmission resources to the source terminal using the DCI, the first activation or deactivation resource set identifier is also carried in the DCI.
[0072] When the source terminal uses SCI or MAC CE to activate or deactivate semi-persistent uplink perception resource configuration for the destination terminal, the resources carrying SCI or MAC CE are allocated by the base station or acquired by the destination terminal through autonomous listening.
[0073] Further optionally, when the source terminal uses SCI to activate or deactivate the semi-persistent uplink sensing resource configuration, the corresponding activated or deactivated semi-persistent uplink sensing resource set identifier (i.e., the third activated or deactivated resource set identifier, which is the first activated or deactivated resource set identifier corresponding to the semi-persistent uplink sensing resource supporting uplink and side link measurement) can be carried using the newly defined SCI format, or the field is placed in the existing SCI format indication. Further optionally, SCI can be detected using a newly defined RNTI different from SL-RNTI and SL-CS-RNTI.
[0074] Further optionally, if the source terminal and the destination terminal are both within the coverage of the base station, the base station obtains information about the source terminal and the destination terminal, and the base station can use a first downlink signaling (such as RRC) to indicate the semi-persistent uplink perception signal resource configuration information to the source terminal and the destination terminal at the same time by multicast, and or use a second downlink signaling (such as DCI or MAC CE) to indicate the resource set identifier of the activated or deactivated semi-persistent uplink perception resource to the source terminal and the destination terminal at the same time. A new multicast DCI or a new RNTI can be newly designed, which is dedicated to supporting multiple terminals to obtain uplink perception signal resource configuration and activation information supporting uplink and side link detection, and the source terminal identifier can be carried in the signaling to clearly indicate the semi-persistent uplink perception signal resource configuration information for the source terminal to send the perception signal.
[0075] If the source terminal and the destination terminal are both within the coverage of the base station, the base station obtains information about the source terminal and the destination terminal, and the base station may also indicate the semi-continuous uplink perception signal resource configuration information and or its corresponding activation or deactivation information of the source terminal to the source terminal and the destination terminal respectively through unicast.
[0076] Mode 3: The type of perception signal resource configuration information indicated by the base station to the source terminal is dynamic, that is, dynamic uplink perception signal resource configuration; the way in which the base station indicates the perception signal resource configuration information to the source terminal is by using DCI indication; the type of perception signal resource configuration information indicated by the source terminal to the destination terminal is dynamic uplink perception signal resource configuration information indicated by the base station to the source terminal; the way in which the source terminal indicates the perception signal resource configuration information to the destination terminal is by using SCI indication; the resource pool occupied by the perception signal is an uplink resource pool.
[0077] For mode 3, it is necessary to further explain that when the base station indicates the dynamic uplink perception signal resource to the source terminal, it can further indicate that the attribute of the resource is only uplink measurement, or supports uplink and side link measurement; if it supports uplink and side link measurement, and the time t1 when the source terminal sends the uplink perception signal using the indicated resource and the time t2 when the source terminal indicates the uplink perception signal resource to the destination terminal satisfy the relationship: t1-t2 is not less than the first time interval G, the source terminal indicates the dynamic uplink perception signal resource configuration information to the destination terminal using SCI. The dynamic uplink perception signal resource indication can be carried using the newly defined SCI format, or the field can be placed in the existing SCI format indication, and the SCI can be detected using a newly defined RNTI that is different from SL-RNTI and SL-CS-RNTI.
[0078] Further optionally, the dynamic uplink perception signal resource configuration information indicated by the base station to the source terminal may be indicated in the signaling by which the base station indicates the side link transmission resources to the source terminal.
[0079] Further optionally, if the source terminal and the destination terminal are both within the coverage of the base station, the base station learns the information of the source terminal and the destination terminal, and the base station can use the first downlink signaling (such as DCI) in a multicast manner to simultaneously indicate the dynamic uplink perception signal resource configuration information to the source terminal and the destination terminal. The first downlink signaling can carry the source terminal identifier to clearly indicate the uplink perception signal resource configuration for the source terminal to send the perception signal; the base station can also indicate the dynamic uplink perception signal resource configuration information of the source terminal to the source terminal and the destination terminal respectively in a unicast manner.
[0080] Mode 4: The type of perception signal resource configuration information indicated by the base station to the source terminal is periodic, that is, periodic side link perception signal resource configuration information; the way in which the base station indicates the perception signal resource configuration information to the source terminal is by using downlink high-level signaling indication (Uu-RRC); the type of perception signal resource configuration information indicated by the source terminal to the destination terminal is the periodic side link perception signal resource configuration information indicated by the base station to the source terminal; the way in which the source terminal indicates the perception signal resource configuration information to the destination terminal is by using side link high-level signaling (PC5-RRC); the perception signal occupied resource pool is a side link resource pool based on base station scheduling.
[0081] Further optionally, if the source terminal and the destination terminal are both within the coverage of the base station, the base station obtains information about the source terminal and the destination terminal, and the base station can use a first downlink signaling (e.g., RRC) in a multicast manner to simultaneously indicate the periodic edge link perception signal resource configuration information to the source terminal and the destination terminal. The first downlink signaling can carry a source terminal identifier to clearly indicate the edge link perception signal resource configuration information for the source terminal to send a perception signal. The base station can also indicate the periodic edge link perception signal resource configuration information of the source terminal to the source terminal and the destination terminal in a unicast manner.
[0082] Mode 5: The type of perception signal resource configuration information indicated by the base station to the source terminal is semi-persistent, that is, semi-persistent side link perception signal resource configuration information; the way in which the base station indicates the perception signal resource configuration information to the source terminal is to first use downlink high-level signaling to indicate the semi-persistent side link perception signal resource configuration information, and then use DCI or MAC CE to activate or deactivate; the type of perception signal resource configuration information indicated by the source terminal to the destination terminal is the semi-persistent side link perception signal resource configuration information indicated by the base station to the source terminal; the way in which the source terminal indicates the perception signal resource configuration information to the destination terminal is to first use side link high-level signaling (PC5-RRC) to indicate the semi-persistent side link perception signal resource configuration information, and then use SCI or MAC CE to activate or deactivate; the perception signal occupied resource pool is an side link resource pool based on base station scheduling.
[0083] Further optionally, when the base station activates or deactivates the semi-persistent side link perception resources to the source terminal, the resource set identifier (i.e., the second activation or deactivation resource set identifier) of the activated or deactivated semi-persistent side link perception resources may be carried in the DCI or MAC CE to indicate which semi-persistent side link perception resource set is activated or deactivated, and the second activation or deactivation resource set identifier may be indicated in the signaling of the side link transmission resources indicated by the base station to the source terminal. For example, when the base station indicates the side link transmission resources to the source terminal using the DCI, the second activation or deactivation resource set identifier is carried in the DCI at the same time.
[0084] Further optionally, when the source terminal uses SCI to activate or deactivate the semi-continuous uplink perception resource configuration, the corresponding activated or deactivated semi-continuous side link perception resource set identifier (i.e., the second activation or deactivation resource set identifier) can be carried using a newly defined SCI format, or the field can be placed in the existing SCI format indication. The SCI can be detected using a newly defined RNTI that is different from SL-RNTI and SL-CS-RNTI.
[0085] Further optionally, if the source terminal and the destination terminal are both within the coverage of the base station, the base station obtains information about the first terminal and the destination terminal, and the base station can use a first downlink signaling (e.g., RRC) in a multicast manner to simultaneously indicate the semi-persistent side link perception signal resource configuration information to the source terminal and the destination terminal, and then use a second downlink signaling to simultaneously indicate to the source terminal and the destination terminal to activate or deactivate the semi-persistent side link perception signal resource configuration. The source terminal identifier can be carried in the first downlink, so that the side link perception signal resource configuration clearly indicated is used for the source terminal to send a perception signal. In addition, the base station can also indicate the semi-persistent side link perception signal resource configuration information of the source terminal, and or the corresponding activation or deactivation information, to the source terminal and the destination terminal respectively in a unicast manner.
[0086] Mode 6: The type of perception signal resource configuration information indicated by the base station to the source terminal is dynamic, that is, dynamic side link perception signal resource configuration information; the way in which the base station indicates the perception signal resource configuration information to the source terminal is by using DCI indication; the type of perception signal resource configuration information indicated by the source terminal to the destination terminal is dynamic side link perception signal resource configuration information indicated by the base station to the source terminal; the way in which the source terminal indicates the perception signal resource configuration information to the destination terminal is by using SCI indication; the perception signal occupied resource pool is a side link resource pool based on base station scheduling.
[0087] For mode 6, it should be further explained that when the source terminal indicates the dynamic side link perception signal resource to the destination terminal, the dynamic side link perception signal resource indication can be carried by using the newly defined SCI format, or the field can be placed in the existing SCI format indication. Further optionally, the SCI can be detected by a newly defined RNTI different from SL-RNTI and SL-CS-RNTI.
[0088] Further optionally, the dynamic side link perception signal resource configuration information indicated by the base station to the source terminal may be indicated in the signaling by which the base station indicates the side link transmission resources to the source terminal.
[0089] Further optionally, if the source terminal and the destination terminal are both within the coverage of the base station, the base station learns the information of the source terminal and the destination terminal, and the base station can use the first downlink signaling (such as DCI) to indicate the dynamic side link perception signal resource configuration information to the source terminal and the destination terminal at the same time by multicast; the source terminal identifier can be carried in the first downlink signaling to clearly indicate the side link perception signal resource configuration for the source terminal to send the perception signal. In addition, the base station can also indicate the dynamic side link perception signal resource configuration of the source terminal to the source terminal and the destination terminal respectively by unicast.
[0090] In step 101, in the above-mentioned methods 1 to 6, further optionally, the source terminal reports to the base station the device identification information of the destination terminal that receives and detects the uplink / side link perception signal, so as to avoid the base station allocating uplink / side link resources to the destination terminal in the time slot corresponding to the uplink / side link perception signal resources, thereby reducing the conflict between the destination terminal receiving and detecting the uplink / side link perception signal of the first terminal and the destination terminal sending the uplink / side link resources.
[0091] In step 101, in the above-mentioned methods 1 to 6, it is further optional that the source terminal and the destination terminal are within the coverage of the base station. Generally, the channel quality of the communication link between the source terminal, the destination terminal and the base station can be used to determine whether they are within the coverage of the base station. For example, if the signal-to-noise ratio SNR is used to measure the channel quality, if the SNR is higher than a certain threshold, it can be determined that it is within the coverage of the base station.
[0092] In step 101, in the above-mentioned methods 1 to 6, it should be further explained that the first downlink signaling and the second downlink signaling may be carried by signaling of different types and formats in different methods. For example, in method 1, the first downlink signaling may be a high-layer signaling, and in method 6, the first downlink signaling may be a physical layer signaling. For the convenience of description, the first downlink signaling and the second downlink signaling are used uniformly to describe.
[0093] Step 102: Transmit a sensing signal that can be used for side link channel measurement on a resource corresponding to each sensing signal resource information.
[0094] In step 102, the source terminal transmits a perception signal that can be used by the destination terminal to perform side link channel measurement on a resource corresponding to each of the perception signal resource information.
[0095] In step 102, the perception signal includes an uplink perception signal and / or a side link perception signal, the uplink perception signal resource information corresponds to the uplink perception signal, and the side link perception signal resource information corresponds to the side link perception signal.
[0096] In step 102, the perception signal may be a reference signal or a dedicated signal designed for perception (e.g., radar) detection; the uplink perception signal may be an uplink reference signal (SRS) or a perception signal designed for uplink or side link channel propagation environment detection; the side link perception signal may be a side link channel state information reference signal (SL-CSI-RS) or a perception signal designed for side link or uplink propagation environment detection.
[0097] In step 102, if the type of the uplink perception signal resource configuration information is periodic, the source terminal will periodically send an uplink perception signal on a corresponding resource according to the uplink perception signal resource information; if the type of the uplink perception signal resource configuration information is semi-continuous, then within the interval of activating and deactivating the uplink perception signal resource by the base station, the uplink perception signal resource information is used to periodically send an uplink perception signal on a corresponding resource; if the type of the uplink perception signal resource configuration information is dynamic, then after the base station indicates the uplink perception signal resource by dynamic signaling, the uplink perception signal resource information is used to send an uplink perception signal on a corresponding resource.
[0098] If the type of the side link perception signal resource configuration information is periodic, the source terminal will periodically send the side link perception signal on the corresponding resource according to the side link perception signal resource information; if the type of the side link perception signal resource configuration information is semi-continuous, then in the interval of activating and deactivating the side link perception resource by the source terminal, the side link perception signal resource information is used to periodically send the side link perception signal on the corresponding resource; if the type of the side link perception signal resource configuration information is dynamic, then after the source terminal indicates the side link perception signal resource by dynamic signaling, the side link perception signal resource information is used to send the side link perception signal on the corresponding resource. The resource pool corresponding to the side link perception signal resource allocated by the base station, or the resource pool corresponding to the side link perception signal sent by the source terminal, is the side link resource pool allocated based on the base station.
[0099] In step 102, for mode 4 in step 101, it is further explained that the resource pool based on base station scheduling can be configured to be shared or not shared with the resource pool based on terminal autonomy. When the source terminal sends the edge link perception signal, the corresponding SCI indicates the time-frequency resource position and period occupied by the periodic edge link perception signal, and a field in the SCI indicates the number of continuous periods, and a value of the field indicates that the terminal will continue to send the periodic edge link perception signal.
[0100] Further optionally, if the resource pool based on base station scheduling and the terminal autonomous resource pool are configured not to be shared, then after the source terminal indicates the periodic edge link perception signal resource configuration information to the destination terminal, after the source terminal receives ACK feedback from the destination terminal for the information, the source terminal does not send the corresponding SCI when using the periodic edge link perception signal resources to send the perception signal.
[0101] In step 102, for mode 5 in step 101, it is further explained that the side link resource pool based on base station scheduling can be configured to be shared or not shared with the resource pool based on terminal autonomy. When the terminal sends the side link perception signal, the corresponding SCI indicates the time-frequency resource position and period occupied by the periodic side link perception signal, and a field in the SCI indicates the number of continuous periods.
[0102] Further optionally, if the resource pool based on base station scheduling and the terminal autonomous resource pool are configured not to be shared, after the source terminal instructs the destination terminal to activate the semi-persistent edge link perception signal resource configuration information, and after the source terminal receives the ACK feedback from the destination terminal for the information, the source terminal does not send the corresponding SCI when sending the perception signal using the semi-persistent edge link perception signal resources.
[0103] If the resource pool based on base station scheduling and the terminal autonomous resource pool are configured not to be shared, then after the base station instructs the destination terminal to activate the semi-persistent edge link perception signal resource configuration information, and after the base station receives the ACK feedback from the destination terminal for the information, the base station can further send confirmation information to the source terminal that the destination terminal has correctly received the activation semi-persistent edge link perception signal resource configuration information. When the source terminal uses the periodic edge link perception signal resource to send the perception signal, it does not send the SCI accordingly.
[0104] If the source terminal and the destination terminal are both within the coverage of the base station, and if the resource pool based on base station scheduling and the terminal autonomous resource pool are configured not to be shared, then after the base station indicates the periodic edge link perception signal resource configuration information to the destination terminal, after the base station receives the ACK feedback of the destination terminal for the information, the base station can further send confirmation information to the source terminal that the destination terminal has correctly received the periodic edge link perception signal resource configuration information, and the source terminal does not send SCI when using the periodic edge link perception signal resource to send the perception signal. Step 103: When the source terminal indicates the perception signal resource configuration information to the destination terminal, it also indicates whether measurement feedback is required.
[0105] In step 103, when the source terminal indicates the uplink / side link perception signal resource configuration information to the destination terminal, it also indicates whether measurement feedback is required, that is, if measurement feedback is required, the destination terminal sends the perception measurement result to the source terminal after receiving the measurement perception signal.
[0106] It should be noted that step 103 is an optional step in the first embodiment.
[0107] An embodiment of the present invention provides a side link perception resource configuration method, which supports a source terminal to send a perception signal to multiple destination terminals at the same time, and supports a terminal to measure a side link channel based on an uplink reference signal, thereby reducing resource overhead and improving resource utilization efficiency.

[0113] Step 202: Send the entire set or a subset of the perception signal resource configuration information through the source terminal.
[0114] In step 202, the whole set or a subset of the perception signal resource configuration information is sent to the destination terminal through the source terminal. It should be noted that the destination terminal may be one or more than one. If there are multiple destination terminals, after the destination terminal completes the perception signal resource configuration, the source terminal may simultaneously send the perception signal to the destination terminal.
[0115] In step 202, if the perception signal resource configuration information sent by the base station to the source terminal is uplink perception signal resource configuration information, then the perception signal resource configuration information sent by the source terminal to the destination terminal is a subset or a full set of the uplink perception signal resource configuration information; if the perception signal resource configuration information sent by the base station to the source terminal is side link perception signal resource configuration information, then the perception signal resource configuration information sent by the source terminal to the destination terminal is the side link perception signal resource configuration information.
[0116] In step 202, it should be noted that if the source terminal and the destination terminal are both within the coverage of the base station, the base station may directly send the perception signal resource configuration information to the source terminal and the destination terminal in a multicast or unicast manner.
[0117] In step 202, when both the source terminal and the destination terminal obtain resource configuration information for sending the perception signal, the source terminal uses the perception signal resource to send the perception signal, and the destination terminal receives and detects the perception signal.
