Description

Technical Field

[0001] The present application relates to the field of mobile communication technologies, and in particular to a method and device for scheduling uplink and downlink sensing resources. Background Art

[0002] In traditional mobile communications, when scheduling uplink communication resources and downlink data channel resources, separate control signaling is usually used for indication. For perception based on mobile communication signals, if the base station wants to perceive the relevant information of non-communication targets in the path between the terminal and the terminal, it is usually necessary for the base station to send information to the terminal for non-communication target perception in the downlink path, the terminal to send information to the base station for non-communication target perception in the uplink path, and the terminal to send information to surrounding terminals for non-communication target perception in the side path. Since the communication link between the base station and the terminal is usually not reciprocal in FDD (frequency division duplex) mode, the perception measurement of the two-way path can obtain richer path information, which is conducive to the extraction of environmental features in the path. Therefore, in the perception based on mobile communication signals, it is necessary to simultaneously configure the downlink from the base station to the terminal and the uplink from the terminal to the base station for perception measurement resources.

[0044] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0046] Figure 1 Schematic diagram of the perception measurement system structure.

[0047] In traditional mobile communications, when scheduling uplink communication resources and downlink data channel resources, separate control signaling is usually used for indication. For example, for 5G systems, the uplink communication resources (PUSCH channel resources, Physical uplink shared channel) between the terminal and the base station are dynamically scheduled by DCI (Downlink control information) format 0_0 / 0_1 / 0_2, and the periodic scheduling based on configuration authorization is indicated by the high-level RRC (Radio Resource Control) signaling BWP_UplinkDedicated. The downlink communication resources (PDSCH channel resources, Physical Downlink Shared Channel) between the base station and the terminal are indicated by DCI format 1_0 / 1_1 / 1_2, and the semi-persistent SPS (Semi-Persistent Scheduling) scheduling is indicated by the high-level RRC signaling BWP_DownlinkDedicated and activated / deactivated by the physical layer DCI. The reference signal resources for uplink and downlink channel measurement (such as downlink CSI-RS and uplink SRS, where CSI-RS stands for Channel State Information-Reference Signal and SRS stands for Sounding Reference Symbol) also include three scheduling methods: periodic, semi-static periodic, and aperiodic. Similar to the indication method of uplink and downlink data channel resources, periodic uplink and downlink reference signal resources are indicated by different RRC IEs in the upper layer, semi-static and aperiodic are activated by different MAC CEs (Media Access Control Channel Elements), and aperiodic uplink and downlink reference signal resources are indicated by the same or different DCIs. Unlike the indication of uplink and downlink data channel resources, since the indication signaling overhead of reference signal resources is relatively small, aperiodic uplink and downlink reference signal resources can be indicated in the same DCI.

[0048] like Figure 1As shown, for perception based on mobile communication signals, if the base station wants to perceive relevant information about non-communication targets in the path between the base station and the terminal and between the terminals, the base station usually needs to send information to the terminal for non-communication target perception in the downlink path, the terminal sends information to the base station for non-communication target perception in the uplink path, and the terminal sends information to surrounding terminals for non-communication target perception in the side path. Since the communication link between the base station and the terminal is usually not reciprocal in FDD mode, perception measurement of the bidirectional path can obtain richer path information, which is conducive to the extraction of environmental features in the path. Therefore, in perception based on mobile communication signals, it is necessary to simultaneously configure the downlink from the base station to the terminal and the uplink from the terminal to the base station for perception measurement resources.

[0049] If the existing resource configuration method is adopted, the main problems are: (1) If uplink and downlink perception measurements are performed based on data channel resources, physical layer DCI is not supported to dynamically schedule uplink and downlink perception measurement resources at the same time. (2) If uplink and downlink perception measurements are performed based on reference signal resources, when periodic uplink and downlink measurement reference signal resources are activated based on RRC high-level signaling or MAC CE, PDSCH channel resources need to be scheduled to carry RRC high-level signaling or MAC CE, and MAC CE signaling is required at the same time when semi-static reference signal resources are deactivated, which is not conducive to fast periodic uplink and downlink measurements. When uplink and downlink measurement reference signal resources are triggered based on DCI, only non-periodic measurements are supported, and periodic tests are not supported. (3) The perception measurement requirements between side links are not considered, and the base station does not support triggering the measurement requirements of the measurement path between terminals when triggering the uplink or downlink path measurement requirements.

[0050] Figure 2(a) is a flow chart of an embodiment of the method of the present application, Figure 2(b) is a first correspondence diagram of an embodiment of the method of the present application, Figure 2(c) is a cell public multicast DCI diagram of an embodiment of the method of the present application, and Figure 2(d) is a second correspondence diagram of an embodiment of the method of the present application, which can be used for perception measurement.

[0051] As an embodiment of the present invention, a method for scheduling uplink and downlink sensing resources specifically includes the following steps 101 to 102:

[0052] Step 101: Design a new downlink control signaling (DCI) to indicate both uplink sensing measurement resource locations and downlink sensing measurement resource locations.

[0053] In step 101, the uplink sensing measurement resources correspond to uplink data channel resources and the downlink sensing measurement resources correspond to downlink data channel resources, or the uplink sensing measurement resources correspond to uplink reference signal resources and the downlink sensing measurement resources correspond to downlink reference signal resources.

[0054] Preferably, the uplink data channel may correspond to PDSCH (Physical Downlink Shared Channel), and the downlink data channel may correspond to PUSCH. The uplink reference signal may correspond to downlink CSI-RS, and the downlink reference signal may correspond to SRS.

[0055] In step 101, the first downlink control signaling is used to simultaneously indicate the location of uplink data channel resources and the location of downlink data channel resources. Specifically, if the uplink and downlink sensing measurement resources correspond to uplink and downlink data channel resources, respectively, the time-frequency locations occupied by the uplink and downlink data channel resources are simultaneously indicated in the first downlink control signaling. The uplink and downlink data channel resources can be dynamically scheduled resources or activated semi-static periodic uplink and downlink data channel resources configured by a higher layer.

[0056] In step 101, there is a first correspondence between the uplink data channel resource position and the downlink data channel resource position. When the first downlink control signaling indicates one of the uplink data channel resource position and the downlink data channel resource position, the other one is also indicated accordingly.

[0057] The first correspondence is shown in Figure 2(b). To save signaling overhead, a higher-level configuration can be used to correspond between downlink data channel resource locations and uplink data channel resource locations. When a downlink data channel resource is indicated via the first downlink control signaling, the corresponding uplink data channel resource is also indicated. Alternatively, when an uplink data channel resource is indicated via the first downlink control signaling, the corresponding downlink data channel resource is also indicated.

[0058] Furthermore, an information field is configured in the first downlink control signaling, and whether the first corresponding relationship is triggered is indicated by the information field. Specifically, when the downlink data channel resource with the first corresponding relationship is indicated by the first downlink control signaling, the configured information field has a value of 1, which indicates that the corresponding uplink data channel resource is indicated at the same time; if the configured information field has a value of 0, it indicates that the corresponding uplink data channel resource is not indicated at the same time. Or when the uplink data channel resource with the first corresponding relationship is indicated by the first downlink control signaling, the configured information field has a value of 1, which indicates that the corresponding downlink data channel resource is indicated at the same time; if the configured information field has a value of 0, it indicates that the corresponding downlink data channel resource is not indicated at the same time.

[0059] It should be noted that, as in the embodiments of the present invention, the first correspondence relationship may not be triggered by configuring the information field with a value of 0, and the first correspondence relationship may be triggered by configuring the information field with a value of 1. Alternatively, the first correspondence relationship may be triggered by configuring the information field with a value of 0, and the first correspondence relationship may be not triggered by configuring the information field with a value of 1. The information field value and whether the first correspondence relationship is triggered are not specifically limited.

[0060] Furthermore, the first corresponding relationship is configured by a high-level layer, and the first corresponding relationship is a corresponding relationship between periodic resources or non-periodic resources. Specifically, the high-level layer configures a periodic data channel resource including information such as resource period, time slot position, symbol position occupied within a time slot, and frequency domain resource position. The high-level layer configures a non-periodic data channel resource including information such as time slot position, symbol position occupied within a time slot, and frequency domain resource position, wherein the time slot position can be determined using a time slot offset K. For example, the time slot n where the downlink control signaling is received is offset by K time slots, which is the position of the non-periodic data channel resource. When the high-level layer configures the first corresponding relationship between uplink and downlink data channel resources, it can configure uplink and downlink data channel resources dedicated to sensing and measuring the first corresponding relationship, for example, configuring N uplink data channel resources and corresponding N downlink data channel resources; it can also configure a corresponding relationship table to associate the P uplink data channel resources and Q downlink data channel resources that the high-level layer has configured.

[0061] It should be noted that K represents the time slot offset, n represents the time slot in which the received downlink control signaling is located, N represents the number of uplink data channel resources under one configuration mode, and also represents the number of downlink data channel resources under the configuration, P represents the number of uplink data channel resources under another configuration mode, and Q represents the number of downlink data channel resources under the other configuration mode.

[0062] Further optionally, the first correspondence is a one-to-one, one-to-many, many-to-one, or many-to-many correspondence. That is, one uplink data channel resource location may correspond to multiple downlink data channel resource locations, or one downlink data channel resource location may correspond to multiple uplink data channel resource locations, or multiple uplink data channel resource locations may correspond to multiple downlink data channel resource locations. The first downlink control signaling indicates which of the multiple correspondences among the one-to-one, one-to-many, many-to-one, or many-to-many correspondences specifically triggers the corresponding data channel resource.

[0063] Optionally, to save signaling, the uplink data channel resource location and the downlink data channel resource location are configured through higher-layer signaling, and the first downlink control signaling indicates the uplink data channel resource identifier and / or the downlink data channel resource identifier. That is, the uplink data channel resource location and / or the downlink data channel resource location are configured through higher-layer signaling, and the first downlink control signaling only indicates the identifier of the data channel resource. For example, if the higher layer has configured P uplink data channel resources and Q downlink data channel resources, when the downlink data channel resource location is indicated through the first downlink control signaling, the first downlink control signaling also includes a field for indicating the uplink data channel resource identifier p (0≤p≤P-1), which is used to indicate the uplink data channel resource location indicated at the same time. When the uplink data channel resource location is indicated through the first downlink control signaling, the first downlink control signaling also includes a field for indicating the downlink data channel resource identifier q (0≤q≤Q-1), which is used to indicate the downlink data channel resource location indicated at the same time.

[0064] Optionally, to reduce resource fragmentation, data channel resources used for sensing measurement and data channel resources used for communication occupy different frequency bands.

[0065] In step 101, the uplink data channel resource position and the downlink data channel resource position are simultaneously indicated through the first corresponding relationship and the data channel resource identifier configured by the higher layer. When the first downlink control signaling needs to simultaneously indicate the uplink data channel resource position and the downlink data channel resource position, when based on the above-mentioned signaling saving method, the data channel resource identifier configured by the first corresponding relationship or the higher layer is used to simultaneously indicate the uplink or downlink data channel resource, if the higher layer only configures part of the information of the data channel resource, the remaining information can be further indicated in the first downlink control signaling. For example, if the higher layer configuration only indicates the frequency domain resource position of the data channel and the symbol position occupied within a time slot, the time slot position of the data channel can be further indicated in the first downlink control signaling.

[0066] In step 101, the second downlink control signaling is used to simultaneously indicate the semi-static periodic uplink reference signal resource location and the downlink reference signal resource location. The third downlink control signaling is used to simultaneously indicate the aperiodic uplink reference signal resource location and the downlink reference signal resource location.

[0067] If the uplink perception measurement resource corresponds to the uplink reference signal resource, and the downlink perception measurement resource corresponds to the downlink reference signal resource, the semi-static periodic uplink reference resource and downlink reference resource configured by the higher layer are simultaneously activated in the second downlink control signaling, or the third downlink control signaling is used to simultaneously indicate the non-periodic uplink reference resource and downlink reference resource, where the second downlink control signaling is UE-level dedicated DCI or cell-level public multicast DCI, and the third downlink control signaling is cell-level public multicast DCI.

[0068] As shown in Figure 2(c), the UE-level dedicated DCI is a dedicated DCI sent to the UE, which only includes control signaling for the UE, and the cell-level public multicast DCI is a public DCI sent to multiple UEs, which includes control signaling for multiple UEs.

[0069] The second downlink control signaling may indicate the corresponding activated periodic uplink reference resources and downlink reference resources. The uplink reference resources and downlink reference resources may be indicated by means of corresponding reference resource set identifiers or resource identifiers. When the second downlink control signaling adopts the cell-level public multicast DCI, the second downlink control signaling may include semi-static periodic uplink and downlink reference resources indicating multiple UEs. Specifically, the second downlink control signaling includes a plurality of indicator blocks (Blocks), each indicator block includes the indicated semi-static periodic uplink and downlink reference resources, and the starting position of the corresponding indication information of each UE in the indicator block is given by the high-level configuration information. Alternatively, the second downlink control signaling includes the cell-level public downlink reference resources, and a plurality of indicator blocks, each indicator block includes the uplink reference resources indicated to the UE, and the starting position of the corresponding indication information of each UE in the indicator block is given by the high-level configuration information.

[0070] In step 101, the third downlink control signaling may indicate corresponding aperiodic uplink and downlink reference resources, or uplink and downlink resource set identifiers. Specifically, the third downlink control signaling includes multiple indicator blocks (Blocks), each indicator block includes indicated aperiodic uplink and downlink reference resources, and the starting position of the corresponding indication information for each UE in the indicator block is given by high-level configuration information. Alternatively, the third downlink control signaling includes cell-level common downlink reference resources and multiple indicator blocks, each indicator block includes uplink reference resources indicated to the UE, and the starting position of the corresponding indication information for each UE in the indicator block is given by high-level configuration information.

[0071] That is, when the second downlink control signaling and the third downlink control signaling are cell-level common multicast DCI, the DCI information format thereof is shown in Table 1 below:

[0072] Table 1 Public multicast DCI format

[0073]

[0074] Step 102: Design a new downlink control signaling (DCI) for simultaneously indicating the sidelink sensing measurement resource location and the uplink sensing measurement resource location, or the sidelink sensing measurement resource location and the downlink sensing measurement resource location, or the sidelink sensing measurement resource location, the uplink sensing measurement resource location, and the downlink sensing measurement resource location.

[0075] In step 102, the sidelink, uplink and downlink sensing measurement resources correspond to sidelink, uplink and downlink data channel resources, or correspond to sidelink, uplink and downlink reference signal resources, respectively.

[0076] It should be noted that sidelink refers to the communication link between terminals. Sidelink, uplink, and downlink data channels can correspond to the PSSCH (physical sidelink shared channel), PDSCH, and PUSCH, respectively. Sidelink, uplink, and downlink reference signals can correspond to the sidelink CSI-RS and downlink CSI-RS and SRS, respectively.

[0077] In step 102, the fourth downlink control signaling is used to simultaneously indicate the sidelink data channel resource location and the uplink data channel resource location, or the sidelink data channel resource location and the downlink data channel resource location, or the sidelink data channel resource location and the uplink data channel resource location and the downlink data channel resource location.

[0078] That is, if the sidelink, uplink, and downlink sensing measurement resources correspond to sidelink, uplink, and downlink data channel resources, then the time-frequency positions occupied by the sidelink and uplink, or sidelink and downlink, or sidelink, uplink, and downlink data channel resources are simultaneously indicated in the fourth downlink control signaling. The sidelink, uplink, and downlink data channel resources may be dynamically scheduled resources or activated semi-static periodic data channel resources configured by a higher layer.

[0079] In step 102, there is a first correspondence between the uplink data channel resource position and the downlink data channel resource position, a second correspondence between the uplink data channel resource position and the sidelink data channel resource position, a third correspondence between the downlink data channel resource position and the sidelink data channel resource position, and a fourth correspondence between the sidelink data channel resource position, the uplink data channel resource position, and the downlink data channel resource position. When the fourth downlink control signaling indicates one of the uplink data channel resource position, the downlink data channel resource position, and the sidelink data channel resource position, the other one or two are also indicated accordingly.

[0080] As shown in Figure 2(d), in order to save signaling overhead, the correspondence between the sidelink, downlink and uplink data channel resources can be configured at a high level. There are four types of correspondence: the correspondence between sidelink and uplink, sidelink and downlink, sidelink and uplink and downlink, and uplink and downlink data channel resources. When the downlink data channel resource is indicated by the fourth downlink control signaling, it means that the corresponding uplink and / or sidelink data channel resources are indicated at the same time. Or when the uplink data channel resource is indicated by the fourth downlink control signaling, it means that the corresponding downlink and / or sidelink data channel resources are indicated at the same time. Or when the sidelink data channel resource is indicated by the fourth downlink control signaling, it means that the corresponding downlink and / or uplink data channel resources are indicated at the same time.

[0081] In step 102, an information field is configured in the fourth downlink control signaling, and whether the first corresponding relationship, the second corresponding relationship, the third corresponding relationship and / or the fourth corresponding relationship are triggered is indicated through the information field.

[0082] The fourth downlink control signaling may be configured with an information field to indicate whether the first to fourth correspondences are triggered. Similar to configuring an information field for the first downlink control signaling in step 101, the specific value representation of the information field in the fourth downlink control signaling is shown in Tables 2 to 4 below:

[0083] Table 2 Corresponding relationship trigger information field values ​​when the fourth DCI indicates downlink data channel resources

[0084]

[0085] Table 3 Corresponding relationship trigger information field values ​​when the fourth DCI indicates uplink data channel resources

[0086]

[0087] Table 4 Corresponding relationship trigger information field values ​​when the fourth DCI indicates sidelink data channel resources

[0088]

[0089] It should be noted that Tables 2 to 4 above illustrate whether the fourth downlink control signaling triggers the first to third correspondences. Whether the fourth correspondence is triggered can also be determined by the value of the information field of the fourth downlink control signaling.

[0090] For example, the fourth downlink control signaling is used to simultaneously indicate the location of the sidelink data channel resource and the location of the uplink data channel resource. An information field is configured in the fourth downlink control signaling, and the information field is used to indicate whether the second corresponding relationship is triggered. When the value of the information field is the first value in Table 2, the corresponding uplink data channel resource and the sidelink data channel resource are activated, and the second corresponding relationship is triggered; when the value of the information field is the second value in Table 2, the corresponding uplink data channel resource is activated, the corresponding sidelink data channel resource is not activated, and the second corresponding relationship is not triggered; when the value of the information field is the third value in Table 3, the corresponding uplink data channel resource is not activated, the corresponding sidelink data channel resource is activated, and the second corresponding relationship is not triggered; when the value of the information field is the fourth value in Table 2, the corresponding uplink data channel resource is not activated, the corresponding sidelink data channel resource is not activated, and the second corresponding relationship is not triggered.

[0091] The meanings of Table 3 and Table 4 are similar to those of Table 2 and are not repeated here.

[0092] Further optionally, the first to fourth corresponding relationships are all one-to-one, one-to-many, many-to-one, or many-to-many corresponding relationships. That is, the corresponding relationship between the sidelink, uplink and downlink data channel resource positions, the corresponding relationship between the uplink data channel resources and the sidelink data channel resources is one-to-one, one-to-many, many-to-one, or many-to-many; the corresponding relationship between the downlink data channel resources and the sidelink data channel resources is one-to-one, one-to-many, many-to-one, or many-to-many; the corresponding relationship between the uplink data channel resources and the downlink data channel resources is one-to-one, one-to-many, many-to-one, or many-to-many. The fourth downlink control signaling indicates which of the multiple corresponding relationships among one-to-one, one-to-many, many-to-one, or many-to-many corresponds to the data channel resource that is specifically triggered.

[0093] Furthermore, the first to third correspondences are configured by the high-level layer, and the first to third correspondences are periodic or non-periodic correspondences. For example, the high-level layer configures periodic or non-periodic correspondences between sidelink, uplink, and downlink data channel resources. Specifically, the high-level layer configures a periodic data channel resource including information such as resource period, time slot position, symbol position occupied within a time slot, and frequency domain resource position. The high-level layer configures a non-periodic data channel resource including information such as time slot position, symbol position occupied within a time slot, and frequency domain resource position, wherein the time slot position can be determined using a time slot offset K. For example, the time slot n where the downlink control signaling is received is offset by K time slots, which is the non-periodic data channel resource position. When the high-level layer configures the correspondence between the sidelink, uplink, and downlink data channel resources, it can configure sidelink, uplink, and downlink data channel resources dedicated to sensing and measuring the correspondence.

[0094] In step 102, the uplink data channel resource position, downlink data channel resource position and sidelink data channel resource position are configured through high-layer signaling, and the fourth downlink control signaling indicates the uplink data channel resource identifier, downlink data channel resource identifier and / or sidelink data channel identifier.

[0095] To save signaling, the sidelink, uplink, and / or downlink data channel resource locations are configured through higher-layer signaling, and the fourth downlink control signaling only indicates the identifier of the data channel resource. For example, if the higher layer has already configured P uplink data channel resources, Q downlink data channel resources, and R sidelink data channel resources, when the downlink data channel resources are indicated through the fourth downlink control signaling, the fourth downlink control signaling also includes a field for indicating the sidelink data channel resource identifier r (0≤r≤R-1) and / or the uplink data channel resource identifier p (0≤p≤P-1) to indicate the sidelink and / or uplink data channel resources indicated simultaneously. When the uplink data channel resources are indicated through the fourth DCI, the fourth downlink control signaling also includes a field for indicating the sidelink data channel resource identifier r (0≤r≤R-1) and / or the downlink data channel resource identifier q (0≤q≤Q-1) to indicate the sidelink and / or downlink data channel resources indicated simultaneously. When the sidelink data channel resource is indicated by the fourth DCI, the fourth downlink control signaling also includes a field for indicating the uplink data channel resource identifier p (0≤p≤P-1) and or indicating the downlink data channel resource identifier (0≤p≤P-1), to indicate the uplink and or downlink data channel resources indicated simultaneously.

[0096] It should be noted that R represents the number of sidelink data channel resources.

[0097] In step 102, the sidelink and uplink data channel resource positions, or the sidelink and downlink data channel resource positions, or the sidelink, uplink and downlink data channel resource positions are simultaneously indicated through the first to fourth correspondences and the data channel resource identifier configured by the higher layer.

[0098] When the fourth downlink control signaling needs to simultaneously indicate the sidelink, uplink, and / or downlink data channel resources, and when, based on the above-mentioned signaling saving method, the data channel resource identifier configured by the corresponding relationship or the higher layer is used to simultaneously indicate the sidelink, uplink, and / or downlink data channel resources, if the higher layer only configures part of the information of the data channel resources, the remaining information can be further indicated in the fourth downlink control signaling. For example, if the higher layer configuration only indicates the frequency domain resource position of the data channel and the symbol position occupied within a time slot, the time slot position of the data channel can be further indicated in the DCI.

[0099] In step 102, the fifth downlink control signaling is used to simultaneously indicate the sidelink reference resource location and the uplink reference resource location, or the sidelink reference resource location and the downlink reference resource location, or the sidelink reference resource location, the uplink reference resource location and the downlink reference resource location.

[0100] If the sidelink, uplink, and downlink sensing measurement resources correspond to sidelink, uplink, and downlink reference signal resources, the sidelink, uplink, and / or downlink reference resources are simultaneously indicated in the fifth downlink control signaling. The fifth downlink control signaling may simultaneously indicate the corresponding sidelink and uplink reference resource identifiers or resource set identifiers, may also simultaneously indicate the corresponding sidelink and downlink reference resource identifiers or resource set identifiers, and may also simultaneously indicate the corresponding sidelink, uplink, and downlink reference resource identifiers or resource set identifiers.

[0101] Specifically, the multicast DCI includes multiple indicator blocks (Blocks), each of which includes indicated sidelink, uplink, and / or downlink reference resources, and the starting position of the corresponding indication information for each UE in the indicator block is given by high-level configuration information. Alternatively, the fifth downlink control signaling includes cell-level common downlink reference resources and multiple indicator blocks, each of which includes sidelink and uplink reference resources indicated to the UE, and the starting position of the corresponding indication information for each UE in the indicator block is given by high-level configuration information. When the fifth DCI is a cell-level common multicast DCI, its information format is shown in Table 5 below:

[0103]

[0104] Figure 3 This is a method flow embodiment of the present application method for a network device, which can be used in network devices such as base stations.

[0105] It should be noted that the sidewalk sensing measurement resources also include sidewalk sensing measurement resources in the terminal self-transmitting and self-receiving mode, that is, the terminal receives the sidewalk sensing measurement signal sent by itself. In this case, the other terminal in the sidewalk sensing measurement signal sent by the terminal to other terminals includes the terminal itself.

[0106] A method for scheduling uplink and downlink sensing resources includes the following steps 201-202:

[0107] Step 201: Use a new downlink control signaling to simultaneously indicate at least two of the following three types of sensing measurement resource locations: an uplink sensing measurement resource location, a downlink sensing resource location, and a sidelink sensing measurement resource location; the sensing measurement resources correspond to data channel resources or reference signal resources.

[0108] In step 201, the uplink sensing measurement resource position corresponds to the uplink data channel resource position, the downlink sensing resource measurement position corresponds to the downlink data channel resource position, and the sidelink sensing measurement resource position corresponds to the sidelink data channel resource position, or the uplink sensing measurement resource position corresponds to the uplink reference signal resource position, the downlink sensing resource measurement position corresponds to the downlink reference signal resource position, and the sidelink sensing measurement resource position corresponds to the sidelink reference signal resource position.

[0109] In step 201, the designed new downlink control signaling is one or more of the first to fifth downlink control signaling in steps 101 to 102.

[0110] In step 201, the new downlink control signaling format is preconfigured for the base station and the terminal at the same time.

[0111] Step 202: The base station sends downlink control signaling to the terminal.

[0112] The downlink control signaling is a new downlink control signaling defined in step 201, and includes at least one of the first downlink control signaling, the second downlink control signaling, the third downlink control signaling, the fourth downlink control signaling and the fifth downlink control signaling in step 101.

[0113] Step 203: The base station sends a downlink perception measurement signal to the terminal.

[0114] If the downlink control signaling in step 202 indicates the resource of the downlink perception measurement signal (which may be a data channel resource or a reference signal resource), the base station sends the corresponding downlink perception measurement signal to the terminal according to the instruction.

[0115] For example, if in step 202, the base station sends a first downlink control signaling to the terminal, and the first downlink control signaling indicates a downlink perception measurement resource, then in step 203, the base station sends a downlink perception measurement signal to the terminal to occupy the indicated downlink perception measurement resource; if in step 202, the base station sends a second downlink control signaling or a third downlink control signaling to the terminal, and the second downlink control signaling or the third downlink control signaling indicates a downlink perception measurement resource, then in step 203, the base station sends a downlink perception measurement signal to the terminal to occupy the indicated downlink perception measurement resource.

[0116] For another example, if the fourth downlink control signaling sent by the base station to the terminal in step 202 includes a downlink perception measurement resource indication, then in step 203, the base station sends a downlink perception measurement signal to the terminal to occupy the indicated downlink perception measurement resource. If the fifth downlink control signaling sent by the base station to the terminal in step 202 includes a downlink perception measurement resource indication, then in step 203, the base station sends a downlink perception measurement signal to the terminal to occupy the indicated downlink perception measurement resource.

[0117] Figure 4 This is a method flow embodiment of the present application method used in a terminal device, which can be used in a terminal device.

[0118] A method for scheduling uplink and downlink sensing resources includes the following steps 301-302:

[0119] Step 301: Use a new downlink control signaling to simultaneously indicate at least two of the following three types of sensing measurement resource locations: an uplink sensing measurement resource location, a downlink sensing resource location, and a sidelink sensing measurement resource location; the sensing measurement resources correspond to data channel resources or reference signal resources.

[0120] In step 301, the uplink sensing measurement resource position corresponds to the uplink data channel resource position, the downlink sensing resource measurement position corresponds to the downlink data channel resource position, and the sidelink sensing measurement resource position corresponds to the sidelink data channel resource position, or the uplink sensing measurement resource position corresponds to the uplink reference signal resource position, the downlink sensing resource measurement position corresponds to the downlink reference signal resource position, and the sidelink sensing measurement resource position corresponds to the sidelink reference signal resource position.

[0121] In step 301, the designed new downlink control signaling is one or more of the first to fifth downlink control signaling in steps 101 to 102.

[0122] In step 301, the new downlink control signaling format is preconfigured for the base station and the terminal at the same time.

[0123] Step 302: The terminal receives downlink control signaling sent by the base station.

[0124] The downlink control signaling is a new downlink control signaling defined in step 302 .

[0125] Step 303: The terminal sends an uplink sensing measurement signal to the base station, or the terminal sends a sidelink sensing measurement signal to other terminals.

[0126] If the downlink control signaling in step 302 indicates an uplink perception measurement resource (which may be a data channel resource or a reference signal resource), the terminal sends an uplink perception measurement signal occupying the indicated uplink perception measurement resource to the base station according to the indication.

[0127] If the downlink control signaling in step 302 indicates the resources of the sidewalk sensing measurement signal (which may be data channel resources or reference signal resources), the terminal sends the sidewalk sensing measurement signal occupying the indicated sidewalk sensing measurement resources to other terminals according to the instruction.
