[0120] Scenario 6: Terminal A transmission and terminal B reception (or UE A transmission and B reception, i.e., UE-UE bistatic). Terminal A transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, terminal B receives and measures the reflected / scattered wave.

[0121] FIG. 1C is a schematic diagram of a sensing scenario, according to an embodiment of the present disclosure. FIG. 1D is a schematic diagram of another sensing scenario, according to an embodiment of the present disclosure.

[0122] In a network environment, when a terminal device transmits a sensing reference signal (S-RS) based on UE monostatic sensing, taking FIG. 1C as an example, for a target with a shorter distance, the S-RS propagation path is relatively shorter; for a target with a longer distance, the S-RS propagation path is relatively longer. In another scenario, the terminal device is under the coverage of a base station device, and transmits an S-RS based on TRP-UE bistatic sensing, taking FIG. 1D as an example, for a position closer to the cell center, that is, closer to the base station device, the S-RS propagation path is relatively shorter; for a target farther away from the base station device, the S-RS propagation path is relatively longer.

[0123] Therefore, in actual sensing services, the UE or the TRP may exist sensing for targets with different distances, which may cause different distance lengths of the propagation paths of the sensing signals. On the premise of maintaining sensing accuracy, different lengths of cyclic prefix (CP) are suitable for different sensing distances. For a long CP, better anti-time delay expansion and anti-multipath interference capabilities can be provided, which means that the device can sense targets with a farther distance. In addition, from the perspective of combining sensing and communication, the sensitivity of communication and sensing to the CP is different, and the distance of the propagation path of the communication signal and the propagation path of the sensing signal is not always the same. Therefore, in the related art, the mechanism of uniformly configuring the CP in the same time slot cannot meet the new integrated sensing and communication requirements.

[0124] Therefore, the embodiment of the present disclosure provides a communication method, a terminal determines the CP length corresponding to the time domain symbol in the first time domain resource, and transmits and / or receives a sensing signal through the first time domain resource, which can improve the transmission and / or reception efficiency of the sensing resource, thereby improving the sensing communication efficiency.

For example, the network device 102 can determine the first information according to the second information, and determine the CP length through the first information.

[0129] For example, the second information can be assistance information, which can also be referred to as UE assistance information. For example, the first information can be CP configuration information.

[0130] For example, the terminal 101 sends the assistance information to the network device 102, and the network device 102 can determine the CP configuration information according to the assistance information, and the CP corresponding length can be determined through the CP configuration information.

[0131] For example, the terminal 101 sends the assistance information to the network device 102, and the network device 102 determines the configuration information of the first time domain resource according to the assistance information. The configuration information of the first time domain resource can include the CP configuration information, and the CP length corresponding to the CP in the first time domain resource can be determined through the CP configuration information.

[0134] In some embodiments, step S2101 is optional, and can be omitted or replaced in different embodiments.

[0135] In step S2102, the network device 102 sends the first information to the terminal 101.

[0136] In some embodiments, the terminal 101 receives the first information sent by the network device 102. The first information is used to determine the CP length.

[0138] In some embodiments, the network device 102 can determine the first information according to the second information sent by the terminal 101, and send the determined first information to the terminal 101.

[0139] For example, the first information can be CP configuration information, or other information used to determine the CP length.

[0140] In some embodiments, the network device 102 can determine the CP configuration information and send the determined CP configuration information to the terminal 101.

[0141] In some embodiments, the network device 102 can determine the CP configuration information according to the assistance information sent by the terminal 101, and send the determined CP configuration information to the terminal 101.

[0142] In some embodiments, the CP configuration information sent by the network device 102 to the terminal 101 can be included in the configuration information of the first time domain resource. That is, the network device 102 can determine the configuration information of the first time domain resource, and the CP configuration information is included in the configuration information of the first time domain resource.

[0143] In some embodiments, the first time domain resource is configured by the network device. The network device can configure the first time domain resource through third signaling, and the third signaling includes at least one of downlink control information (DCI), media access control-control element (MAC CE), and radio resource control (RRC) signaling.

[0144] In some embodiments, the first time domain resource can be used for transmitting a sensing signal. Wherein, the transmission can include sending and / or receiving. The first time domain resource used for transmitting a sensing signal can be that the first time domain resource is used for sending and / or receiving a sensing signal. That is, the first time domain resource can be used for sending a sensing signal, the first time domain resource can also be used for receiving a sensing signal, and the first time domain resource can also be used for both sending and receiving a sensing signal.

[0145] In some embodiments, the first time domain resource can be used for sending and / or receiving a communication signal.

[0146] In some embodiments, the first time domain resource can be used for sending and / or receiving a sensing signal and / or a communication signal.

[0147] For sensing services, the network device 102 and the terminal 101 jointly complete sensing signal transmission and reception, or the network device 102 configures the first time domain resource for the terminal 101, and the terminal 101 itself completes sensing signal transmission and reception, or the network device 102 configures the first time domain resource for the terminal 101, and multiple terminal devices complete sensing signal transmission and reception. For communication services, the network device 102 and the terminal 101 jointly complete communication signal transmission and reception.

[0148] In some embodiments, the CP configuration information can include CP indirect configuration information and CP direct configuration information. The CP indirect configuration information and the CP length have a mapping relationship, and the CP length can be determined through the CP indirect configuration information and the mapping relationship. The CP length can be directly determined through the CP direct configuration information.

[0149] In some embodiments, the CP length and the first information have a mapping relationship. The first information includes at least one of the following: a service type; a target distance; and a target range.

[0150] The service type can include a sensing service and a communication service, and the service type can also include different types of sensing services, such as a service with a long sensing distance and a service with a short sensing distance. The target distance can be a sensing distance and / or a communication distance, and the target range refers to a sensing range and / or a communication range.

[0151] In some embodiments, the network device indicates / configures the indirect related configuration of the CP, and the terminal determines the CP length of the time domain symbol in the first time domain resource. The related configuration includes at least one of the following: a service type, a target distance, and a target range.

[0152] In some embodiments, the protocol predefines at least one of the following rules: a mapping relationship between the CP length and a sensing service; and a mapping relationship between the CP length and a target distance / range.

[0153] Optionally, the mapping relationship can be determined by a mapping table predefined by the protocol. The mapping table can include at least one of the following: μ, a subcarrier spacing, a service type, a distance range, and different types of CPs. μ represents a related parameter of the subcarrier spacing, for example, μ is 0 representing 15 kHz, and μ is 1 representing 30 kHz. The different types of CPs can include at least one of the following: a normal CP (NCP), an extended CP (ECP), a long CP (LCP), and an extended long CP (ELCP).

[0154] In some embodiments, the mapping relationship between the CP length and the service type can be determined by the protocol, for example, by Table 1. Under the premise of the same subcarrier spacing size, LCP>ECP>NCP in Table 1. For example, the network device indicates through the DCI that the service currently scheduled in the first time domain resource is a sensing service, and the CP length is confirmed as the length corresponding to LCP.

[0155] Table 1

[0156] In some embodiments, the mapping relationship between the CP length and the target distance can be determined by a protocol, for example, by Table 2. In Table 2, under the same subcarrier spacing size, ELCP > LCP > ECP > NCP. For example, the network device indicates through the DCI that the target distance of the sensing service currently scheduled in the first time domain resource is greater than 500, and the CP length is confirmed as the length corresponding to ELCP.

[0157] Table 2

[0158] It can be understood that the data in the above table is only an example, and in the actual sensing and communication process, the data in the mapping table can be set according to the actual situation, and the present disclosure does not limit this.

[0159] In some embodiments, the CP length is determined based on the first information, and the first information includes at least one of the following: CP length; CP length index; CP type; offset from anchor CP; offset from anchor SCS; ratio to anchor CP; and CP distribution pattern in consecutive time domain symbols.

[0160] In some embodiments, the network device indicates / configures the direct related configuration of the CP, and then the terminal determines the CP length of the time domain symbol in the first time domain resource. The direct configuration includes at least one of the following: CP length, CP length index, CP type, offset from baseline CP, offset from baseline SCS, ratio to baseline CP, and CP pattern in a period of consecutive time domain symbols.

[0161] The CP length can be an absolute CP length (for example, 33.33us) or a relative length (for example, 10% of the time domain symbol).

[0162] The CP length index refers to the index value corresponding to the CP length. For example, the index value 0 corresponds to the CP length of 33.33us, and the index value 1 corresponds to the CP length of 66.66us.

[0163] The CP type refers to the type of the CP. For example, NCP, ECP, LCP, ELCP, etc. In the case of the same SCS, the length size relationship corresponding to different CP types is: NCP < ECP < LCP < ELCP.

[0164] The offset from the baseline CP refers to the offset value from the anchor CP. The protocol predefines that the anchor CP corresponds to the offset value 0, the first CP corresponds to the offset value 1, the second CP corresponds to the offset value 2, and so on. The anchor CP can be a configured CP for communication service or a determined CP for CP length.

[0165] Wherein, the offset from baseline SCS refers to the offset value from the anchor SCS. The protocol predefines that the anchor SCS corresponds to the offset value 0, the first SCS corresponds to the offset value 1, the second SCS corresponds to the offset value 2, and so on. The anchor SCS can be the SCS configured for communication service, or the SCS with a determined SCS size. The CP on the symbol corresponding to different SCS is not the same. The baseline SCS corresponds to the CP value on the baseline SCS. By the offset value corresponding to different SCS, the CP value corresponding to SCS is determined.

[0166] Wherein, the ratio to baseline CP refers to the multiple compared with the anchor CP, and the ratio is a natural number greater than 0. The anchor CP can be the CP configured for communication service, or the CP with a determined CP length.

[0167] Wherein, the CP pattern of consecutive time domain symbols refers to the distribution pattern of time domain symbols of two different types of CP (for example, normal CP and enhanced CP) in consecutive time domain symbols. The number of consecutive time domain symbols can be any positive integer, for example, 4, 5, 6, 7, 8, 10, 12, 16, 20, 32, etc. For example, taking the number 4 as an example, the normal CP is NCP, and the corresponding time domain symbol is indicated by 1; the enhanced CP is LCP, and the corresponding time domain symbol is indicated by 0. Then 1010 represents that the CP length of the first time domain symbol is NCP, the CP length of the second time domain symbol is LCP, 1010 represents that the CP length of the third time domain symbol is NCP, and 1010 represents that the CP length of the fourth time domain symbol is LCP.

[0168] Step S2103, the terminal 101 determines the CP length.

[0169] In some embodiments, the terminal 101 determines the CP length of the time domain symbol in the first time domain resource.

[0170] In some embodiments, the terminal 101 determines the CP length of the time domain symbol in the first time domain resource according to the CP configuration information sent by the network device 102.

[0171] In some embodiments, when the first information includes at least one of the service type, the target distance, and the target range, the terminal determines the CP length according to the mapping relationship between the first information and the CP length.

[0172] For example, when the first information includes the service type, the terminal can determine the CP type corresponding to the service type included in the first information according to Table 1, and determine the CP length according to the CP type.

[0173] For example, the first information includes a target distance, and the terminal can determine the CP length corresponding to the target distance included in the first information according to Table 2, and determine the CP length according to the CP type.

[0174] In some embodiments, the first information includes at least one of the CP length; the CP length index; the CP type; the offset from the anchor CP; the offset from the anchor SCS; the ratio to the anchor CP; and the distribution pattern of the CP in the consecutive time domain symbols, and the terminal directly determines the CP length according to the first information.

[0175] For example, the first information indicates that the CP length is 66.66us, and the terminal determines that the CP length of the time domain symbol in the first time domain resource is 66.66us.

[0176] For example, the communication CP is the anchor CP, the first information indicates that the offset from the baseline CP is 2, and the terminal determines that the CP of the time domain symbol in the first time domain resource is the second CP.

[0177] For example, the first information indicates that the CP pattern is 1010 (the normal CP is NCP, and the corresponding time domain symbol is indicated by 1; the enhanced CP is LCP, and the corresponding time domain symbol is indicated by 0); and the terminal determines that the first time domain resource includes 4 time domain symbols, 1010 represents that the CP length of the first time domain symbol is NCP, 1010 represents that the CP length of the second time domain symbol is LCP, 1010 represents that the CP length of the third time domain symbol is NCP, and 1010 represents that the CP length of the fourth time domain symbol is LCP.

[0178] For example, the communication CP is the anchor CP, the first information indicates that the offset from the baseline CP is 2 and the CP pattern is 1010. The terminal determines that the first time domain resource is 4 time domain symbols, the CP of the first time domain symbol is the anchor CP, the CP of the second time domain symbol is the second CP, the CP of the third time domain symbol is the anchor CP, and the CP of the fourth time domain symbol is the second CP.

[0179] In step S2104, the network device 102 sends the first signaling to the terminal 101.

[0180] In some embodiments, the terminal 101 receives the first signaling sent by the network device 102.

[0181] The first signaling is used to activate the first time domain resource.

[0182] In some embodiments, the communication and / or sensing service is transmitted on the first time domain resource, which is configured by the network device. The network device configures the first time domain resource through third signaling, which includes at least one of but is not limited to DCI, MAC CE, and RRC signaling. Further, the network device activates the first time domain resource configured by the third signaling through first signaling, which includes at least one of but is not limited to DCI, MAC CE, and RRC signaling.

[0183] At step S2105, the network device 102 sends the second signaling to the terminal 101.

[0184] In some embodiments, the terminal 101 receives the second signaling sent by the network device 102.

[0185] The second signaling is used to deactivate the first time domain resource.

[0186] In some embodiments, the network device deactivates the first time domain resource configured by the third signaling through the second signaling, which includes at least one of but is not limited to DCI, MAC CE, and RRC signaling.

[0187] In some embodiments, the first time domain resource is used to transmit and / or receive a sensing signal, which is used to obtain sensing measurement data, and the sensing measurement data is used to determine a sensing measurement result. The sensing signal can include a sensing reference signal (sensing RS).

[0188] For example, the terminal sends a sensing RS to the network device based on the first time domain resource; the network device performs measurement based on the sensing RS to obtain a sensing measurement result, and sends the sensing measurement result to the terminal.

[0189] For another example, the network device sends a sensing RS to the terminal based on the first time domain resource; the terminal performs measurement based on the sensing RS to obtain sensing measurement data, and sends the sensing measurement data to the network device; the network device obtains a sensing measurement result based on the sensing measurement data, and sends the sensing measurement result to the terminal.

[0190] For another example, the terminal sends a sensing RS to another terminal based on the first time domain resource, and the other terminal receives the sensing RS and performs measurement based on the sensing RS to obtain a sensing measurement result.

[0191] In some embodiments, step S2104 and step S2105 can be both performed, only one of them can be performed, or both of them can be omitted. For example, the network device 102 sends the first signaling to the terminal 101. For another example, the network device 102 sends the second signaling to the terminal 101. For yet another example, the network device 102 sends the first signaling to the terminal 101, and the network device 102 sends the second signaling to the terminal 101.

[0197] In some embodiments, step S2102 is optional, and one or more of the steps can be omitted or replaced in different embodiments.

[0198] In some embodiments, other optional implementations described before or after the description corresponding to FIG. 2A can be referred to.

[0199] FIG. 2B is an interaction schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2B, the embodiments of the present disclosure relate to a communication method, and the above method includes:

[0204] In some embodiments, the CP configuration information can include CP indirect configuration information and CP direct configuration information. The CP indirect configuration information and the CP length have a mapping relationship, and the CP length can be determined through the CP indirect configuration information and the mapping relationship.

[0208] In some embodiments, the CP length is determined based on a predefined rule, and the predefined rule includes a mapping relationship between the CP length and third information; the third information includes at least one of the following: a target distance; a service type; a terminal device moving speed.

[0209] In some embodiments, the terminal can determine the CP length based on the predefined rule.

[0210] In some embodiments, the protocol binds the CP length and the target distance. For example, when the target measurement distance is <50m, a first CP is used, and when the target measurement distance is >50m, a second CP is used.

[0211] In some embodiments, the protocol pre-defines the CP length to be bound to a service type. For example, a first CP is used when a communication service is used, and a second CP is used when a sensing service is used.

[0212] In some embodiments, the protocol pre-defines the CP length to be bound to a terminal device speed. For example, a first CP is used when the terminal device speed is < 120 km / h, and a second CP is used when the terminal device speed is > 120 km / h.

[0213] The first CP and the second CP correspond to different CP lengths respectively, and the CP length of the first CP is smaller than the CP length of the second CP. The lengths of the first CP and the second CP can be pre-defined.

[0214] In step S2202, the terminal 101 sends first information to the network device 102.

[0215] The first information is used to determine the CP length.

[0216] In some embodiments, after the terminal 101 determines the first information (for example, CP configuration information), the terminal 101 can send the first information to the network device 102, so as to realize information synchronization between the terminal and the network device.

[0221] In some embodiments, when the CP configuration information includes at least one of a service type, a target distance, and a target range, the terminal determines the CP length according to a mapping relationship between the CP configuration information and the CP length.

[0222] For example, when the CP configuration information includes a service type, the terminal can determine the CP type corresponding to the service type included in the CP configuration information according to Table 1, and determine the CP length according to the CP type.

[0223] For example, when the CP configuration information includes a target distance, the terminal can determine the CP length corresponding to the target distance included in the CP configuration information according to Table 2, and determine the CP length according to the CP type.

[0226] The communication method provided by the embodiments of the present disclosure can improve the transmission efficiency of the sensing resource, and thus improve the sensing communication efficiency, by determining the CP length corresponding to the time domain symbol in the first time domain resource by the terminal, since the CP length is determined by the CP configuration information, and the CP configuration information is related to the sensing service, and the sensing signal is transmitted and / or received through the first time domain resource.

For example, step S2201 can be implemented as an independent embodiment, steps S2201+S2202 can be implemented as an independent embodiment, and steps S2201+S2203 can be implemented as an independent embodiment, but are not limited thereto.

[0244] In some embodiments, for the terminal self-initiated self-received sensing scenario, the terminal 101 can send and receive sensing signals. For example, the terminal 101 sends a sensing signal to a sensing target, and the terminal 101 receives a sensing signal returned from the sensing target. The sensing signal can include a sensing reference signal.

[0245] In step S2304, the terminal 101 sends a sensing signal to the network device 102.

[0475] In some embodiments, the communication and / or sensing service is transmitted on the first time domain resource, which is configured by the network device. The network device configures the first time domain resource through first signaling, which includes at least one of DCI, MAC CE, and RRC signaling.

[0476] In some embodiments, the specific configuration method includes at least one of the following methods.

[0477] In some embodiments, the network device indicates / configures the indirect correlation configuration of the CP through the first signaling, and then determines the CP length of the time domain symbol in the first time domain resource. The correlation configuration includes at least one of the service type, the target distance of the probe, and the target range of the probe.

[0478] In some embodiments, the protocol predefines at least one of the following rules:

[0479] The mapping relationship between the CP length and the sensed service;

[0480] The mapping relationship between the CP length and the target distance / range of the probe.

[0481] Optionally, the mapping relationship can be determined by a protocol predefined mapping table. The actual mapping table contains elements including at least one of μ, subcarrier spacing, service type, distance range, and different types of CP.

[0482] In one implementation, the protocol determines the mapping relationship between the CP length and the sensed service through a second mapping table, specifically as shown in Table 1, under the premise of the same subcarrier spacing size, LCP>ECP>NCP. For example, the base station device indicates through DCI that the service currently scheduled on the first time domain resource is a sensing service, and then the CP length is confirmed based on LCP.

[0483] In one implementation, the protocol determines the mapping relationship between the CP length and the target distance X of the probe through a first mapping table, specifically as shown in Table 2, under the premise of the same subcarrier spacing size, ELCP>LCP>ECP>NCP. For example, the base station device indicates through DCI that the target distance of the sensing service currently scheduled on the first time domain resource is greater than 500, and then the CP length is confirmed based on ELCP.

[0484] The above implementation is only for example.

[0485] In some embodiments, the network device indicates / configures the direct related configuration of CP through the first signaling, and then determines the CP length of the time domain symbol in the first time domain resource. The direct configuration includes at least one of the CP length, the CP length index, the CP type, the baseline CP offset, the baseline SCS offset, the baseline CP ratio, and the CP in a certain CP pattern of a certain continuous time domain symbol.

[0486] The CP length can be an absolute CP length (for example, 33.33us) or a relative CP length (for example, 10% of the time domain symbol).

[0487] The CP length index refers to the index value corresponding to the CP length. For example, the index value 0 corresponds to the CP length of 33.33us, and the index value 1 corresponds to the CP length of 66.66us.

[0488] The CP type refers to the type of CP. For example, NCP, ECP, LCP, ELCP, and the like. In the case of the same SCS, NCP<ECP<LCP<ELCP.

[0489] The baseline CP offset refers to the offset value of the anchor CP. The protocol predefines that the anchor CP corresponds to the offset value 0, the first CP corresponds to the offset value 1, the second CP corresponds to the offset value 2, and the like.

The continuous time domain symbol can be any positive integer, and typical values are 4, 5, 6, 7, 8, 10, 12, 16, 20, 32, etc. For example, taking 4 as an example, the normal CP is NCP, and the corresponding time domain symbol is indicated by 1; the enhanced CP is LCP, and the corresponding time domain symbol is indicated by 0. Then 1010 represents that the CP length of the first time domain symbol is NCP, 1010 represents that the CP length of the second time domain symbol is LCP, 1010 represents that the CP length of the third time domain symbol is NCP, and 1010 represents that the CP length of the fourth time domain symbol is LCP.

[0493] In an implementation manner, the base station device indicates that the CP length value is 66.66us, and the CP length of each time domain symbol in the first time domain resource in this configuration is 66.66us.

[0494] In an implementation manner, the communication CP is an anchor CP, and when the base station device indicates that the baseline CP offset value is 2, the CP of each time domain symbol in the first time domain resource in this configuration is the second CP.

[0495] In an implementation manner, the base station device indicates that the CP pattern is 1010, and the first time domain resource in this configuration is also 4 time domain symbols, the normal CP is NCP, and the corresponding time domain symbol is indicated by 1; the enhanced CP is LCP, and the corresponding time domain symbol is indicated by 0.

The CP of the first time domain symbol in the first time domain resource in this configuration is an anchor CP, the CP of the second time domain symbol is a second CP, the CP of the third time domain symbol is an anchor CP, and the CP of the fourth time domain symbol is a second CP.

[0497] The above implementation manners are only examples.

[0504] Optionally, the mapping relationship can be determined by a protocol pre-defined mapping table. The actual mapping table contains elements including at least one of μ, subcarrier spacing, service type, distance range, and different types of CP.

[0505] Further, the network device activates the indirect related configuration of CP through the second signaling, thereby determining the CP length of the time domain symbol in the first time domain resource.

[0506] In one implementation, the base station device configures the communication service corresponding to NCP and the sensing service corresponding to LCP through RRC signaling. When the base station device triggers and activates through MAC CE, the CP of the time domain symbol of the first time domain resource corresponding to the activated communication service is NCP, and the CP of the time domain symbol of the first time domain resource corresponding to the sensing service is LCP.

The protocol predefines that the anchor CP corresponds to the offset value 0, the first CP corresponds to the offset value 1, the second CP corresponds to the offset value 2, and so on.

[0513] The baseline CP ratio refers to the multiple compared with the anchor CP, which is a natural number greater than 0. The anchor CP can be the CP of the configured communication service, or the CP with a specified CP length.

[0514] The CP pattern in a segment of continuous time domain symbols refers to the distribution pattern of normal CP and enhanced CP time domain symbols in continuous time domain symbols. The continuous time domain symbols can be any positive integer, and typical values are 4, 5, 6, 7, 8, 10, 12, 16, 20, and 32. For example, taking 4 as an example, the normal CP is NCP, and the corresponding time domain symbol is indicated by 1. The enhanced CP is LCP, and the corresponding time domain symbol is indicated by 0. Then 1010 represents that the CP length of the first time domain symbol is NCP, 1010 represents that the CP length of the second time domain symbol is LCP, 1010 represents that the CP length of the third time domain symbol is NCP, and 1010 represents that the CP length of the fourth time domain symbol is LCP.

[0516] In one implementation, the base station device is configured by RRC signaling, and the sensing service corresponds to a CP length of 66.66us. When the base station device is triggered and activated by the MAC CE, the CP length of the time domain symbol of the first time domain resource of the activated sensing service is 66.66us.

[0517] Based on the above, further, the network device deactivates the first time domain resource configured by the first signaling through the third signaling, which includes at least one of DCI, MAC CE, and RRC signaling.

[0518] In some embodiments, the communication and / or sensing service is transmitted on the first time domain resource, which is configured by the network device. Further, the CP-related configuration in the first time domain resource configuration is reported to the network device by the terminal device through the fourth signaling, which includes at least one of UCI, MAC CE, and RRC signaling.

[0519] The specific configuration method includes at least one of the following methods.

[0524] Optionally, the mapping relationship can be determined by the protocol pre-defined mapping table. The actual mapping table contains elements including at least one of the following: subcarrier spacing, service type, distance range, and different types of CP.

[0525] In one implementation, the protocol determines the mapping relationship between the CP length and the sensing service through the second mapping table, specifically as shown in Table 1, under the premise of the same subcarrier spacing size, LCP>ECP>NCP. For example, the UE device indicates through the UCI that the service currently scheduled in the first time domain resource is a sensing service, and the CP length is confirmed based on LCP.

[0526] In one implementation, the protocol determines the mapping relationship between the CP length and the target distance X of the probe through the first mapping table, as shown in Table 2. Under the premise of the same subcarrier spacing size, ELCP > LCP > ECP > NCP. For example, the UE device indicates through the UCI that the target distance of the sensing service currently scheduled in the first time domain resource is greater than 500, and the CP length is confirmed as ELCP based.

[0527] The above implementation is only for example.

[0535] The CP in the CP pattern of a continuous time domain symbol refers to the distribution pattern of normal CP and enhanced CP in the time domain symbol. The continuous time domain symbol can be any positive integer, and typical values are 4, 5, 6, 7, 8, 10, 12, 16, 20, 32. For example, taking 4 as an example, the normal CP is NCP, and the corresponding time domain symbol is indicated by 1; the enhanced CP is LCP, and the corresponding time domain symbol is indicated by 0.
