Background
In conventional mobile communication, when scheduling uplink communication resources and downlink data channel resources, separate control signaling is usually used for indication.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a perception measurement system.
In conventional mobile communication, when scheduling uplink communication resources and downlink data channel resources, separate control signaling is usually used for indication. For example, for a 5G system, the uplink communication Resource (PUSCH channel Resource, Physical uplink shared channel) between a terminal and a base station is indicated by DCI (Downlink Control information) format 0_0/0_1/0_2 in dynamic scheduling, and is indicated by higher layer RRC (Radio Resource Control) signaling BWP _ uplink modified based on the periodic scheduling of configuration grant. Downlink communication resources (PDSCH Channel resources, Physical Downlink Shared Channel) from the base station to the terminal are indicated by DCI format 1_0/1_1/1_2, and Semi-persistent SPS (Semi-persistent scheduling) scheduling is indicated by higher layer RRC signaling BWP _ Downlink dedicated and is activated/deactivated by Physical layer DCI. Reference Signal resources (such as downlink CSI-RS and uplink SRS, wherein CSI-RS is a channelstatic information-Reference Signal, a channel information Reference Signal, and SRS is sounding symbol, a Reference Signal) for uplink and downlink channel measurement also include three scheduling modes, i.e., periodic, semi-static periodic and non-periodic. In the same manner as the indication manner of the uplink and downlink data Channel resources, the periodic uplink and downlink reference signal resources are indicated by using different RRCIE at the high layer, the semi-static aperiodic mac ce (Media Access Control Channel Element) is activated by using different MACCE, and the non-periodic uplink and downlink reference signal resources are indicated by using the same or different DCI. Different from the indication of uplink and downlink data channel resources, the indication signaling overhead of the reference signal resources is low, so that the non-periodic uplink and downlink reference signal resources can be indicated in the same DCI.
As shown in fig. 1, for sensing based on mobile communication signals, if a base station wants to sense information related to non-communication targets in paths between terminals and between terminals, it is generally required that the base station sends information to the terminals for sensing the non-communication targets in a downlink path, the terminals send information to the base station for sensing the non-communication targets in an uplink path, and the terminals send information to surrounding terminals for sensing the non-communication targets in a sideline path. Because a communication link between a base station and a terminal does not have reciprocity generally in an FDD mode, sensing measurement of a bidirectional path can acquire richer path information, and the extraction of environmental characteristics in the path is facilitated. Therefore, in mobile communication signal sensing, downlink from the base station to the terminal and uplink from the terminal to the base station need to be configured simultaneously for sensing measurement resources.
If the existing resource allocation mode is adopted, the main problems exist: (1) if the uplink and downlink sensing measurement is carried out based on the data channel resources, the physical layer DCI is not supported to dynamically schedule the uplink and downlink sensing measurement resources at the same time. (2) if the uplink and downlink sensing measurement is performed based on the reference signal resource, when the reference signal resource is measured based on the RRC high-level signaling or the mac ce activated periodic uplink and downlink, the PDSCH channel resource needs to be scheduled to carry the RRC high-level signaling or the mac ce, and the mac ce signaling is needed when the semi-static reference signal resource is deactivated, which is not beneficial to the rapid periodic uplink and downlink measurement. And when the DCI-triggered uplink and downlink measurement reference signal resources are used, only aperiodic measurement is supported, and periodic test is not supported. (3) The sensing measurement requirement between the sidelink is not considered, and the base station is not supported to trigger the measurement requirement of the measurement path between the terminal and the terminal while triggering the measurement requirement of the uplink or downlink path.
Fig. 2(a) is a flowchart of an embodiment of the present application method, fig. 2(b) is a schematic diagram of a first corresponding relationship of the embodiment of the present application method, fig. 2(c) is a schematic diagram of a cell common multicast DCI of the embodiment of the present application method, and fig. 2(d) is a schematic diagram of a second corresponding relationship of the embodiment of the present application method, which may be used for sensing measurement.
As an embodiment of the invention, a method for scheduling uplink and downlink sensing resources specifically comprises the following steps of 101-102:
step 101, designing a new downlink control signaling (DCI) for simultaneously indicating the location of the uplink sensing measurement resource and the location of the downlink sensing measurement resource.
In step 101, the uplink sensing measurement resource corresponds to an uplink data channel resource, and the downlink sensing measurement resource corresponds to a downlink data channel resource, or the uplink sensing measurement resource corresponds to an uplink reference signal resource and the downlink sensing measurement resource corresponds to a downlink reference signal resource.
Preferably, the uplink data Channel may correspond to a PDSCH (Physical Downlink Shared Channel), and the Downlink data Channel may correspond to a PUSCH. The uplink reference signal may correspond to a downlink CSI-RS, and the downlink reference signal may correspond to an SRS.
In step 101, the first downlink control signaling is used to indicate the location of the uplink data channel resource and the location of the downlink data channel resource at the same time. Specifically, if the uplink and downlink sensing measurement resources correspond to uplink and downlink data channel resources, the time-frequency positions occupied by the uplink data channel resources and the downlink data channel resources are indicated in the first downlink control signaling at the same time. The uplink and downlink data channel resources may be dynamically scheduled resources or activated semi-static periodic uplink and downlink data channel resources configured in a higher layer.
In step 101, a first corresponding relationship exists between the uplink data channel resource location and the downlink data channel resource location, and when the first downlink control signaling indicates one of the uplink data channel resource location and the downlink data channel resource location, the other is also correspondingly indicated.
The first corresponding relationship is shown in fig. 2(b), and in order to save signaling overhead, the corresponding relationship between the downlink data channel resource location and the uplink data channel resource location may be configured at a high level. When the first downlink control signaling indicates the downlink data channel resource therein, it means that the corresponding uplink data channel resource is indicated at the same time. Or when the uplink data channel resource is indicated through the first downlink control signaling, it means that the corresponding downlink data channel resource is indicated at the same time.
Further, 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 resources having the first correspondence are indicated by the first downlink control signaling, if the configured information field value is 1, it indicates that the corresponding uplink data channel resources are indicated at the same time, and if the configured information field value is 0, it indicates that the corresponding uplink data channel resources are not indicated at the same time. Or when the uplink data channel resources having the first corresponding relationship are indicated through the first downlink control signaling, if the value of the configured information domain is 1, it indicates that the corresponding downlink data channel resources are indicated at the same time, and if the value of the configured information domain is 0, it indicates that the corresponding downlink data channel resources are not indicated at the same time.
It should be noted that, in this embodiment of the present invention, a first corresponding relationship is not triggered by setting the configured information field to be 0, and a first corresponding relationship is triggered by setting the configured information field to be 1. The first corresponding relationship may also be triggered by the configured information domain value being 0, and the first corresponding relationship is not triggered by the configured information domain value being 1, where the first corresponding relationship is not specifically limited by the information domain value and whether the first corresponding relationship is triggered.
Further, the first corresponding relationship is configured through a high layer, and the first corresponding relationship is a corresponding relationship between periodic resources or non-periodic resources. Specifically, the high layer configures a periodic data channel resource including information such as a resource period, a slot position, a symbol position occupied in a slot, a frequency domain resource position, and the like. The high layer configures an aperiodic data channel resource comprising information such as a time slot position, a symbol position occupied in a time slot, a frequency domain resource position and the like, wherein the time slot position can be determined by using a time slot offset K, and if n time slots offset by K time slots of a time slot where a downlink control signaling is received are the aperiodic data channel resource position. When the first corresponding relation between the uplink data channel resources and the downlink data channel resources is configured by the high layer, the uplink data channel resources and the downlink data channel resources which are specially used for sensing and measuring the first corresponding relation can be configured, for example, N uplink data channel resources and corresponding N downlink data channel resources are configured; or configuring a corresponding relation table to associate and correspond the P uplink data channel resources and Q downlink data channel resources configured by the high layer.
It should be noted that K represents a time slot offset, N represents a time slot in which a received downlink control signaling is located, N represents the number of uplink data channel resources in one configuration mode and also represents the number of downlink data channel resources in the configuration, P represents the number of uplink data channel resources in another configuration mode, and Q represents the number of downlink data channel resources in the another configuration mode.
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. And indicating the data channel resource corresponding to which one of the one-to-one correspondence, the one-to-many correspondence, the many-to-one correspondence or the many-to-many correspondence is specifically triggered in the first downlink control signaling.
Optionally, to save signaling, the uplink data channel resource location and the downlink data channel resource location are configured by a high-level signaling, and the first downlink control signaling indicates an uplink data channel resource identifier and/or a downlink data channel resource identifier. That is, the uplink data channel resource position and/or the downlink data channel resource position are configured by the high-level signaling, and the first downlink control signaling only indicates the identifier of the data channel resource. For example, when the position of the downlink data channel resource is indicated by the first downlink control signaling, the first downlink control signaling simultaneously includes a field for indicating an uplink data channel resource identifier P (P is greater than or equal to 0 and less than or equal to P-1) to indicate the position of the uplink data channel resource indicated at the same time. When the position of the uplink data channel resource is indicated through the first downlink control signaling, the first downlink control signaling simultaneously comprises a domain for indicating a downlink data channel resource identifier Q (Q is more than or equal to 0 and less than or equal to Q-1) for indicating the simultaneously indicated position of the downlink data channel resource.
Optionally, in order to reduce fragmentation of resources, the data channel resources for sensing measurement and the data channel resources for communication occupy different frequency bands.
In step 101, the uplink data channel resource location and the downlink data channel resource location are indicated simultaneously through the first corresponding relationship and the data channel resource identifier configured in the higher layer. When the first downlink control signaling needs to indicate the uplink data channel resource location and the downlink data channel resource location at the same time, and when the uplink or downlink data channel resource is indicated at the same time through the first corresponding relationship or the data channel resource identifier configured by the higher layer based on the signaling saving method, if the higher layer only configures part of the information of the data channel resource, the rest information can be further indicated in the first downlink control signaling. For example, the higher layer configuration only indicates the frequency domain resource position of the data channel and the occupied symbol position in one slot, and the slot position of the data channel may be further indicated in the first downlink control signaling.
In step 101, the second downlink control signaling is used to indicate the semi-static periodic uplink reference signal resource location and the downlink reference signal resource location at the same time. And the third downlink control signaling is used for indicating the position of the non-periodic uplink reference signal resource and the position of the downlink reference signal resource at the same time.
If the uplink sensing measurement resource corresponds to an uplink reference signal resource and the downlink sensing measurement resource corresponds to a downlink reference signal resource, then activating a high-level configured semi-static periodic uplink reference resource and a downlink reference resource simultaneously in a second downlink control signaling or adopting a third downlink control signaling to indicate an aperiodic uplink reference resource and a downlink reference resource simultaneously, wherein the second downlink control signaling is UE-level dedicated DCI or cell-level common multicast DCI, and the third downlink control signaling is cell-level common multicast DCI.
As shown in fig. 2(c), the UE-level dedicated DCI is a dedicated DCI transmitted to the UE and only includes control signaling for the UE, and the cell-level common multicast DCI is a common DCI transmitted to a plurality of UEs and includes control signaling for the plurality of UEs.
The second downlink control signaling may indicate the corresponding activated periodic uplink reference resource and activated downlink reference resource. The uplink reference resource and the downlink reference resource can be indicated by means of a corresponding reference resource set identifier or a corresponding resource identifier. When the second downlink control signaling adopts cell-level common 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 multiple indication blocks (blocks), each indication Block includes indicated semi-static periodic uplink and downlink reference resources, and a start position of each UE in the indication Block corresponding to the indication information is given by higher layer configuration information. Or, the second downlink control signaling includes a cell-level common downlink reference resource and a plurality of indication blocks, each indication block includes an uplink reference resource indicated to the UE, and a starting position of each UE in the indication block corresponding to the indication information is given by the high-layer configuration information.
In step 101, the second 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 a plurality of indication blocks (blocks), each indication Block includes an indicated aperiodic uplink and downlink reference resource, and each UE is given by high layer configuration information at a start position of the indication Block corresponding to the indication information. Or, the third downlink control signaling includes a cell-level common downlink reference resource and a plurality of indication blocks, each indication block includes an uplink reference resource indicated to the UE, and a starting position of each UE in the indication block corresponding to the indication information is given by the high-layer configuration information.
That is, when the second downlink control signaling and the third downlink control signaling are cell-level common multicast DCI, the DCI information formats thereof are shown in table 1 below:

102, designing a new downlink control signaling (DCI) for simultaneously indicating a position of a side-line sensing measurement resource and a position of an uplink sensing measurement resource, or the position of the side-line sensing measurement resource and the position of the downlink sensing measurement resource, or the position of the side-line sensing measurement resource and the position of the uplink sensing measurement resource and the position of the downlink sensing measurement resource.
In step 102, the side row, uplink and downlink sensing measurement resources correspond to side row, uplink and downlink data channel resources, respectively, or correspond to side row, uplink and downlink reference signal resources, respectively.
It should be noted that the side row refers to a terminal and a communication link between terminals. The sidelink data channel, the uplink data channel, and the downlink data channel may correspond to a psch (physical sidelink shared channel), a PDSCH (physical side link control channel), and a PUSCH, respectively. The side-row, uplink, and downlink reference signals may correspond to side-row CSI-RS and downlink CSI-RS and SRS, respectively.
In step 102, the fourth downlink control signaling is configured to indicate the position of the sidelink data channel resource and the position of the uplink data channel resource, or the position of the sidelink data channel resource and the position of the downlink data channel resource, or the position of the sidelink data channel resource and the position of the uplink data channel resource and the position of the downlink data channel resource at the same time.
That is, if the side row, uplink and downlink sensing measurement resources correspond to the side row, uplink and downlink data channel resources, the time-frequency positions occupied by the side row and uplink, or the side row and downlink, or the side row and uplink and downlink data channel resources are indicated in the fourth downlink control signaling at the same time. The resources of the sideline data channel, the uplink data channel and the downlink data channel can be dynamic scheduling resources or activated semi-static periodic data channel resources configured by a high layer.
In step 102, a first corresponding relationship exists between the uplink data channel resource location and the downlink data channel resource location, a second corresponding relationship exists between the uplink data channel resource location and the sideline data channel resource location, a third corresponding relationship exists between the downlink data channel resource location and the sideline data channel resource location, a fourth corresponding relationship exists between the sideline data channel resource location and the uplink data channel resource location and the downlink data channel resource location, and when the fourth downlink control signaling indicates one of the uplink data channel resource location, the downlink data channel resource location, and the sideline data channel resource location, the other one or both are also correspondingly indicated.
As shown in fig. 2(d), in order to save signaling overhead, the corresponding relationship between the resources of the sideline data channel, the downlink data channel and the uplink data channel can be configured at a high level. The corresponding relationship includes four kinds: and the corresponding relation between side row and uplink, side row and downlink, side row and uplink and downlink, and uplink and downlink data channel resources. When the fourth downlink control signaling indicates the downlink data channel resources therein, it means that the corresponding uplink and/or sidelink data channel resources are indicated at the same time. Or when the fourth downlink control signaling indicates the uplink data channel resources therein, it indicates that the corresponding downlink, and/or sideline data channel resources are indicated at the same time. Or when the fourth downlink control signaling indicates the sideline data channel resource, it indicates that the corresponding downlink and/or uplink data channel resource is indicated at the same time.
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 is triggered is indicated by the information field.
An information field may be configured and utilized in the fourth downlink control signaling to indicate whether to trigger the first to fourth mapping relationships. Similarly to step 101, an information field is configured for the first downlink control signaling, and the meaning of the specific value mode expression of the information field in the fourth downlink control signaling is shown in the following tables 2 to 4:
TABLE 2 the fourth DCI indicates the corresponding relationship trigger information field value under the condition of downlink data channel resource
Figure BDA0003591846690000131
Table 3 corresponding relation trigger information field value under the condition that the fourth DCI indicates the uplink data channel resource
Figure BDA0003591846690000132
TABLE 4 corresponding relationship trigger information field dereferencing under the condition that the fourth DCI indicates a side-row data channel resource
Figure BDA0003591846690000141
It should be noted that, the above tables 2 to 4 exemplify whether the fourth downlink control signaling triggers the first to third corresponding relationships, and whether the fourth corresponding relationship is triggered may also be judged by the information domain value of the fourth downlink control signaling.
For example, the fourth downlink control signaling is configured to indicate the position of the sidelink data channel resource and the position of the uplink data channel resource at the same time, and an information field is configured in the fourth downlink control signaling, where the information field is used to indicate whether to trigger the second corresponding relationship. When the value of the information domain is the first value in table 2, activating corresponding uplink data channel resources and sideline data channel resources, and triggering a second corresponding relationship; when the value of the information field is the second value in table 2, activating the corresponding uplink data channel resource, not activating the corresponding side data channel resource, and not triggering the second corresponding relationship; 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 side 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 side data channel resource is not activated, and the second corresponding relationship is not triggered.
The meanings of tables 3 and 4 are similar to those of table 2 and are not repeated here.
Further optionally, the first to fourth correspondences are all one-to-one, one-to-many, many-to-one, or many-to-many correspondences. Namely the corresponding relation between the positions of the sideline data channel resources and the uplink and downlink data channel resources, wherein the corresponding relation between the uplink data channel resources and the sideline data channel resources is one-to-one, one-to-many, many-to-one or many-to-many; the corresponding relation between the downlink data channel resources and the side 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. And indicating the data channel resource corresponding to which one of the multiple corresponding relations among one-to-one, one-to-many, many-to-one or many-to-many is specifically triggered in the fourth downlink control signaling.
Further, the first to third correspondences are configured by a high level, and the first to third correspondences are periodic or aperiodic correspondences. For example, the high layer configures the periodic or non-periodic corresponding relationship of the resources of the sidelines, the uplink and the downlink data channels. Specifically, the high layer configures a periodic data channel resource including information such as a resource period, a slot position, a symbol position occupied in a slot, a frequency domain resource position, and the like. The high layer configures a non-periodic data channel resource including information such as a time slot position, a symbol position occupied in a time slot, a frequency domain resource position, and the like, wherein the time slot position can be determined by using a time slot offset K, and if a time slot n at which a downlink control signaling is received is offset by K time slots, the non-periodic data channel resource position is the non-periodic data channel resource position. When the high layer configures the corresponding relation among the resources of the side row, the uplink data channel and the downlink data channel, the resources of the side row, the uplink data channel and the downlink data channel which are specially used for sensing and measuring and have the corresponding relation can be configured.
In step 102, the uplink data channel resource location, the downlink data channel resource location, and the side data channel resource location are configured by a high-level signaling, and the fourth downlink control signaling indicates an uplink data channel resource identifier, a downlink data channel resource identifier, and/or a side data channel identifier.
In order to save signaling, the resource positions of the sideline, uplink and/or downlink data channels are configured through high-level signaling, and the fourth downlink control signaling only indicates the identification of the data channel resource. For example, P uplink data channel resources, Q downlink data channel resources, and R side data channel resources already configured by the higher layer, when the downlink data channel resources are indicated by the fourth downlink control signaling, the fourth downlink control signaling simultaneously includes a field for indicating a side data channel resource identifier R (R is greater than or equal to 0 and less than or equal to R-1), and/or an uplink data channel resource identifier P (P is greater than or equal to 0 and less than or equal to P-1), so as to indicate the side and/or uplink data channel resources indicated at the same time. When the uplink data channel resource is indicated through the fourth DCI, the fourth downlink control signaling simultaneously comprises a field for indicating a side row data channel resource identifier R (R is more than or equal to 0 and less than or equal to R-1), and or indicating a downlink data channel resource identifier Q (Q is more than or equal to 0 and less than or equal to Q-1) for indicating the side row and or the downlink data channel resource indicated simultaneously. When the side data channel resource is indicated through the fourth DCI, the fourth downlink control signaling simultaneously comprises a domain for indicating an uplink data channel resource identifier P (P is more than or equal to 0 and less than or equal to P-1), and or indicating a downlink data channel resource identifier (P is more than or equal to 0 and less than or equal to P-1) for indicating the uplink and or downlink data channel resource indicated simultaneously.
Note that R represents the number of sidelink data channel resources.
In step 102, the positions of the resources of the sidelines and the uplink data channel, or the positions of the resources of the sidelines and the downlink data channel, or the positions of the resources of the sidelines, the uplink and the downlink data channel are indicated at the same time through the first to the fourth corresponding relations and the data channel resource identifier configured at the high layer.
When the fourth downlink control signaling needs to indicate the resources of the side row, the uplink and/or the downlink data channel at the same time, and when the data channel resource identifier configured through the corresponding relationship or the high layer is used to indicate the resources of the side row, the uplink and/or the downlink data channel at the same time based on the signaling saving method, if the high layer is configured with only part of the information of the data channel resources, the rest information can be further indicated in the fourth downlink control signaling. For example, the higher layer configuration only indicates the frequency domain resource position of the data channel and the symbol position occupied in one slot, the slot position of the data channel may be further indicated in the DCI.
In step 102, the fifth downlink control signaling is used to indicate the position of the sidelink reference resource and the position of the uplink reference resource, or the position of the sidelink reference resource and the position of the downlink reference resource, or the position of the sidelink reference resource and the position of the uplink reference resource and the position of the downlink reference resource at the same time.
And if the side row, uplink and downlink sensing measurement resources correspond to the side row, uplink and downlink reference signal resources, indicating the side row, uplink and/or downlink reference resources in the fifth downlink control signaling at the same time. The fifth downlink control signaling may indicate the corresponding side row and uplink reference resource identifier or resource set identifier simultaneously, may also indicate the corresponding side row and downlink reference resource identifier or resource set identifier simultaneously, and may also indicate the corresponding side row, uplink and downlink reference resource identifier or resource set identifier simultaneously.
Specifically, the multicast DCI includes multiple indication blocks (blocks), each indication Block includes indicated sideline, uplink and/or downlink reference resources, and each UE gives a start position corresponding to indication information in the indication Block through high-layer configuration information. Or, the fifth downlink control signaling includes a cell-level common downlink reference resource and a plurality of indication blocks, each indication block includes a sideline and an uplink reference resource indicated to the UE, and a start position of each UE in the indication block corresponding to the indication information is given by the high-layer configuration information. When the fifth DCI is a cell-level common multicast DCI, the information format thereof is shown in table 5 below:

It should be noted that the side-line sensing measurement resource also includes a side-line sensing measurement resource in a self-sending and self-receiving mode of the terminal, that is, the terminal receives a side-line sensing measurement signal sent by itself. And at the moment, the other terminals in the side row perception measurement signals sent by the terminal to the other terminals comprise the terminal.
A method for scheduling uplink and downlink sensing resources comprises the following steps 201-202:
step 201, using a new downlink control signaling to indicate at least two of the following three sensing measurement resource locations simultaneously: an uplink sensing measurement resource position, a downlink sensing measurement resource position and a side-line sensing measurement resource position; the sensing measurement resource corresponds to a data channel resource or a reference signal resource.

Step 203, the base station sends a downlink sensing measurement signal to the terminal.
If the downlink control signaling indicates the resource of the downlink sensing measurement signal (which may be a data channel resource or a reference signal resource) in step 202, the base station sends the corresponding downlink sensing measurement signal to the terminal according to the indication.
For example, if the base station sends a first downlink control signaling to the terminal in step 202, and the first downlink control signaling indicates a downlink sensing measurement resource, in step 203, the base station sends a downlink sensing measurement signal occupying the indicated downlink sensing measurement resource to the terminal; if the base station sends the second downlink control signaling or the third downlink control signaling to the terminal in step 202, and the second downlink control signaling or the third downlink control signaling indicates the downlink sensing measurement resource, the base station sends a downlink sensing measurement signal occupying the indicated downlink sensing measurement resource to the terminal in step 203.
For another example, if the fourth downlink control signaling sent by the base station to the terminal in step 202 includes the downlink sensing measurement resource indication, the base station sends a downlink sensing measurement signal occupying the indicated downlink sensing measurement resource to the terminal in step 203. If the fifth downlink control signaling sent by the base station to the terminal in step 202 includes the downlink sensing measurement resource indication, in step 203, the base station sends a downlink sensing measurement signal occupying the indicated downlink sensing measurement resource to the terminal.
