[0102] Integrated communication and sensing technology, based on integrated design including spectrum resource sharing, integrated air interface, and integrated hardware architecture, as well as multi-point collaboration and intelligent information interaction, enables mobile communication systems to simultaneously possess communication capabilities and sensing capabilities such as positioning, detection, imaging, and recognition. The integrated communication and sensing system includes two operating modes: independent sensing mode and collaborative sensing mode.

[0103] Among them, reference Figure 1 In the independent sensing mode, node A sends a sensing signal and receives the reflected signals of each sensing target to the sensing signal, thereby obtaining the characteristic parameters of the surrounding environment. Based on this, sensing functions such as target detection, localization, recognition, and tracking are realized.

[0104] Reference Figure 2 In the collaborative sensing mode, node A sends a sensing signal and coordinates with node B to receive the reflected signals from each sensing target. Then, through information interaction and information fusion processing, the nodes obtain the environmental feature parameters between them.

[0105] In related technologies, to avoid interference between uplink and downlink signals, adjacent base stations need to unify the cell-level frame structure configuration for communication signals, that is, such as... Figure 3 As shown, the communication downlink of base station A is consistent with the communication downlink of base station B, and the communication uplink of base station A is consistent with the communication uplink of base station B. In practical applications, the cell-level frame structure configuration of the communication signal cannot be modified. For the sensing signal in the above cooperative sensing mode, the sensing downlink of base station A and the sensing uplink of base station B must be configured in pairs. As a result, in the integrated communication and sensing system, the frame structure of the communication signal and the sensing signal cannot be compatible.

[0106] Based on this, in this embodiment of the application, the receiving base station of the sensing signal receives a first configuration, wherein the first configuration includes: the frame structure configuration of the transmitting base station of the sensing signal regarding the sensing signal, and / or, the frame structure configuration of the receiving base station regarding the sensing signal, and the first configuration is configured on the flexible time slots of the frame structure of the communication signal. The above scheme adds the frame structure of the sensing signal to the frame structure of the communication signal, and unifies the frame structure configuration of the sensing signal between the transmitting base station and the receiving base station of the sensing signal, ensuring compatibility between the communication signal and the sensing signal in the integrated communication and sensing system.

[0107] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0108] In this embodiment, the first base station, acting as the receiver of the sensing signal, and the second base station, acting as the transmitter of the sensing signal, are configured with a unified third frame structure. Here, the third frame structure can be understood as the cell-level frame structure time slot configuration of the communication signal. This unifies the frame structure configuration of the communication signal between the first and second base stations. Based on this, this embodiment adds a frame structure configuration for the sensing signal to the frame structure of the communication signal, i.e., the third frame structure, and distributes this frame structure configuration to the first base station. This further unifies the frame structure configuration of the sensing signal between the first and second base stations, thereby ensuring compatibility between the communication signal and the sensing signal in the integrated communication and sensing system.

[0109] In practical applications, the frame structure configuration of the sensing signal can be sent from the second base station to the first base station. Specifically, the second base station can send either the first base station's first frame structure configuration or the second base station's second frame structure configuration to the first base station via the Xn interface or air interface. It should be noted that, since the uplink and downlink of the sensing signal need to be configured in pairs, even if the second base station sends its second frame structure configuration to the first base station, the first base station can still determine its first frame structure configuration based on this characteristic.

[0110] In practical applications, the sensing server can also send the frame structure configuration of the sensing signal to the first base station and the second base station. This frame structure configuration includes: a first frame structure configuration of the sensing signal for the first base station and a second frame structure configuration of the sensing signal for the second base station. Based on the above scheme, this application embodiment provides a configuration method applied to the first base station, referred to below. Figure 4 The method includes:

[0111] Step 401: Receive the first configuration.

[0112] Here, the first configuration includes: the first frame structure configuration of the first base station with respect to the sensed signal, and / or the second frame structure configuration of the second base station with respect to the sensed signal.

[0113] As mentioned above, the first configuration is configured on a flexible time slot of a third frame structure, which characterizes the frame structure of the communication signal.

[0114] In one embodiment, receiving the first configuration includes:

[0115] Receive the first configuration sent by the first node. Here, the first node can be understood as a perception server. Correspondingly, the first configuration includes: the first frame structure configuration and the second frame structure configuration.

[0116] In one embodiment, receiving the first configuration includes:

[0117] The system receives a first configuration sent by the second base station. Correspondingly, the first configuration includes either a first frame structure configuration or a second frame structure configuration.

[0118] Based on the above scheme, this application embodiment also provides a configuration method applied to a second base station, as shown below. Figure 5 The method includes:

[0119] Step 501: Send the first configuration.

[0120] Here, the first configuration includes: the first frame structure configuration of the first base station with respect to the sensed signal, or the second frame structure configuration of the second base station with respect to the sensed signal.

[0121] As mentioned above, the first configuration is configured on a flexible time slot of a third frame structure, which characterizes the frame structure of the communication signal.

[0122] Next, the first configuration will be explained in detail.

[0123] In this embodiment of the application, a frame structure of a sensing signal is added to the frame structure of the communication signal. The corresponding configuration principle includes: configuring the frame structure of the sensing signal on the flexible time slot of the frame structure of the communication signal to ensure compatibility with the uplink and downlink time slots of the communication signal.

[0124] In one embodiment, the first configuration characterizes the frame structure configuration at the time slot level of the sensing signal, and is used to configure the time slot where the sensing signal is located.

[0125] For the frame structure configuration of communication signals, in an uplink / downlink switching cycle, the unconfigured time-domain resources between downlink and uplink transmission resources are flexible resources, including flexible time slots and flexible symbols. Therefore, for the frame structure configuration at the time slot level of sensing signals, based on the configuration principles mentioned above, the frame structure of sensing signals is configured on the flexible time slots of the frame structure of communication signals.

[0126] In one embodiment, the first frame structure configuration includes:

[0127] First time slot offset and number of first time slots.

[0128] The first time slot offset represents the offset relative to the first position, which represents the end position of the uplink and downlink time slot switching cycle of the third frame structure. The first time slot offset is used to indicate the end position of the uplink sensing time slot, and the number of first time slots represents the number of uplink sensing time slots.

[0129] See Figure 6 Example, in Figure 6In one uplink / downlink time slot switching cycle of the cell-level frame structure of the communication signal shown, there are 3 full downlink time slots (time slot 0, time slot 1, and time slot 2) and 3 full uplink time slots (time slot 7, time slot 8, and time slot 9). The downlink resource length of the communication signal is... Figure 6 The uplink resource length of the communication signal, shown as x1+x2, is... Figure 6 The diagram shows y1+y2. For the first base station, in the first frame structure configuration, the first time slot offset us1 = 5, and the number of first time slots us2 = 1. Thus, by offsetting the first time slot by 5 relative to the end position of time slot 9 (i.e., the end position of the uplink / downlink time slot switching cycle of the third frame structure), the end position of the uplink sensing time slot is determined to be the end position of time slot 4. Since the number of first time slots is 1, i.e., the number of uplink sensing time slots is 1, the first base station can thus determine time slot 4 as the uplink time slot for sensing signals.

[0130] Alternatively, in one embodiment, the first frame structure configuration includes:

[0131] Second time slot offset and number of first time slots.

[0132] The second time slot offset represents the offset relative to the second position, which represents the end position of the first full uplink time slot up to the end position of the uplink / downlink time slot switching cycle of the third frame structure. The second time slot offset is used to indicate the end position of the uplink sensing time slot, and the number of the first time slots represents the number of uplink sensing time slots.

[0133] Similarly, see Figure 6 For example, for the first base station, in the first frame structure configuration, the second time slot offset us1 = 3 and the number of first time slots us2 = 1. Thus, by offsetting the second time slot by 3 relative to the end position of time slot 7 (i.e., the end position of the uplink / downlink time slot switching cycle of the third frame structure is the end position of the first full uplink time slot), the end position of the uplink sensing time slot is determined to be the end position of time slot 4. Since the number of first time slots is 1, that is, the number of uplink sensing time slots is 1, the first base station can determine time slot 4 as the uplink time slot of the sensing signal.

[0134] Both of the aforementioned time-slot-level first frame structure configurations enable the first base station to determine the uplink transmission position of the sensing signal within the cell-level frame structure configuration of the communication signal, and the determined uplink transmission position of the sensing signal is the same in both configurations. Based on this, the first base station can receive the echo signal of the sensing signal at this uplink transmission position.

[0135] In one embodiment, the second frame structure configuration includes:

[0136] The offset of the third time slot and the number of second time slots.

[0137] The third time slot offset represents the offset relative to the third position, which represents the starting position of the uplink and downlink time slot switching cycle of the third frame structure. The third time slot offset is used to indicate the starting position of the downlink sensing time slot, and the number of the second time slots represents the number of downlink sensing time slots.

[0138] Similarly, see Figure 6 For example, for the second base station, in the second frame structure configuration, the third time slot offset ds1 = 4 and the number of second time slots ds2 = 1. Thus, by offsetting the third time slot by 4 relative to the starting position of time slot 0 (i.e. the starting position of the uplink and downlink time slot switching cycle of the third frame structure), the starting position of the downlink sensing time slot is determined to be the starting position of time slot 4. Since the number of second time slots is 1, that is, the number of downlink sensing time slots is 1, the second base station can determine time slot 4 as the downlink time slot for sensing signals.

[0139] Alternatively, in one embodiment, the second frame structure configuration includes:

[0140] The fourth time slot offset and the number of second time slots.

[0141] The fourth time slot offset represents the offset relative to the fourth position, which represents the starting position of the last full downlink time slot starting from the starting position of the uplink and downlink time slot switching cycle of the third frame structure. The fourth time slot offset is used to indicate the starting position of the downlink sensing time slot, and the number of the first time slots represents the number of downlink sensing time slots.

[0142] Similarly, see Figure 6 For example, for the second base station, in the second frame structure configuration, the fourth time slot offset ds1 = 2 and the number of second time slots ds2 = 1. Thus, by offsetting the fourth time slot by 2 relative to the starting position of time slot 2 (i.e., the starting position of the last full downlink time slot starting from the starting position of the uplink and downlink time slot switching cycle of the third frame structure), the starting position of the downlink sensing time slot is determined to be the starting position of time slot 4. Since the number of second time slots is 1, that is, the number of downlink sensing time slots is 1, the second base station can determine time slot 4 as the downlink time slot for sensing signals.

[0143] Both of the aforementioned time-slot-level second frame structure configurations enable the second base station to determine the downlink transmission location of the sensing signal within the cell-level frame structure configuration of the communication signal, and the determined downlink transmission location of the sensing signal is the same in both configurations. Based on this, the second base station can complete the transmission of the sensing signal at this downlink transmission location.

[0144] and, Figure 6In the example, the number of downlink sensing time slots is the same as the number of uplink sensing time slots, and both downlink and uplink sensing time slots are located on time slot 4 of the frame structure of the communication signal. Time slot 4 is also a flexible time slot of the frame structure of the communication signal. It can be seen that based on the first frame structure configuration and the second frame structure configuration, the sensing signal and the communication signal are compatible, and the sensing signal achieves unified uplink and downlink configuration.

[0145] In one embodiment, the first configuration represents the frame structure configuration at the symbol level of the sensing signal, used to configure the symbol where the sensing signal is located, and, as described above, in this embodiment of the application, the sensing signal is configured to be transmitted on a flexible time slot of the third frame structure, i.e., the frame structure of the communication signal.

[0146] The following scenario focuses on a single measurement of the sensed signal by the first base station:

[0147] In one embodiment, the sensing signal is transmitted on a flexible time slot adjacent to the full downlink time slot of the third frame structure. Correspondingly, the first frame structure configuration includes: a first downlink communication symbol number, a first flexible symbol number, and a first uplink sensing symbol number; the second frame structure configuration includes: a second downlink communication symbol number and a first downlink sensing symbol number, wherein the first flexible symbol number is equal to the difference between the second downlink communication symbol number and the first downlink symbol number.

[0148] Here, the sensing signal is transmitted on a flexible time slot adjacent to the full downlink time slot of the third frame structure, that is, the sensing signal is transmitted on a flexible time slot immediately following the full downlink time slot of the third frame structure. On this flexible time slot, the number of downlink communication symbols ranges from 0 to 13.

[0149] For example, suppose the number of first downlink communication symbols is x2(b), x2(b) = 1, the number of second downlink communication symbols is x2(a), x2(a) = 4, the number of first flexible symbols is x2(a) - x2(b), x2(a) - x2(b) = 3, the number of first uplink sensing symbols is us2, us2 = 2, and the number of first downlink sensing symbols is ds2, ds2 = 2. Then, referring to... Figure 7For base station A, i.e., the second base station, in the flexible time slot immediately following the full downlink time slot of the third frame structure, the ds2 symbols following the x2(a) downlink communication symbols starting from the start symbol of this flexible time slot are the first downlink sensing symbols, that is, the 5th and 6th symbols are the first downlink sensing symbols. For base station B, i.e., the first base station, in the flexible time slot immediately following the full downlink time slot of the third frame structure, the x2(b) downlink communication symbols following the start symbol of this flexible time slot and the us2 symbols following the x2(a)-x2(b) flexible symbols are the first uplink sensing symbols, that is, the 5th and 6th symbols are the first uplink sensing symbols. Thus, it can be seen that based on the configuration of the first frame structure and the configuration of the second frame structure, the sensing signal and the communication signal are compatible, and the sensing signal achieves symbol-level unified uplink and downlink configuration.

[0150] In another embodiment, the sensing signal is transmitted on a flexible time slot adjacent to the full uplink time slot of the third frame structure. Correspondingly, the first frame structure configuration includes a first number of uplink communication symbols, and the second frame structure configuration includes a second number of uplink communication symbols, wherein the first number of uplink communication symbols is equal to the second number of uplink communication symbols.

[0151] Here, the sensing signal is transmitted on a flexible time slot adjacent to the full uplink time slot of the third frame structure. That is, the sensing signal is transmitted on the flexible time slot immediately preceding the full uplink time slot of the third frame structure. On this flexible time slot, the number of uplink communication symbols ranges from 0 to 13.

[0152] For example, in the first frame structure configuration: the number of first uplink communication symbols is y2(b), y2(b) = 1; in the second frame structure configuration, the number of second uplink communication symbols is y2(a), y2(a) = 1, y2(b) = y2(a). Then, referring to... Figure 8 In the flexible time slot immediately preceding the full uplink time slot in the third frame structure, for the first base station, except for the last y2(a) symbols of this flexible time slot which are uplink communication symbols, all other symbols are used as flexible symbols and can be used to configure uplink sensing symbols. For the second base station, except for the last y2(b) symbols of this flexible time slot which are downlink communication symbols, all other symbols are used as flexible symbols and can be used to configure downlink sensing symbols. It should be noted here that... Figure 8 In this flexible time slot, except for the last symbol, which is the 14th symbol, which is an uplink communication symbol, the remaining symbols from the 1st to the 13th are all used as flexible symbols. Figure 8 The symbols shown in the first to thirteenth sections represent only one example of resource configuration.

[0153] Alternatively, in another embodiment, the first frame structure configuration includes: a first number of uplink communication symbols, and the second frame structure configuration includes: a second number of uplink communication symbols and a second number of flexible symbols, wherein the first number of uplink communication symbols is equal to the sum of the second number of uplink communication symbols and the second number of flexible symbols.

[0154] Here, the sensing signal is transmitted on a flexible time slot adjacent to the full uplink time slot of the third frame structure. That is, the sensing signal is transmitted on the flexible time slot immediately preceding the full uplink time slot of the third frame structure. On this flexible time slot, the number of uplink communication symbols ranges from 0 to 13.

[0155] For example, in the first frame structure configuration: the number of first uplink communication symbols is y2(b), y2(b) = 3; in the second frame structure configuration: the number of second uplink communication symbols is y2(a), y2(a) = 1; the number of second flexible symbols is f2(a), f2(a) = 2; y2(b) = y2(a) + f2(a). Then, referring to... Figure 9 In the flexible time slot immediately preceding the full uplink time slot in the third frame structure, for the first base station, except for the last y2(b) symbols of this flexible time slot which are uplink communication symbols, all other symbols are used as flexible symbols and can be used to configure uplink sensing symbols. For the second base station, except for the last y2(a)+f2(a) symbols of this flexible time slot, all other symbols are used as flexible symbols and can be used to configure downlink sensing symbols. It should be noted here that... Figure 9 In this flexible time slot, except for the last three symbols, the first through tenth symbols are all used as flexible symbols. Figure 9 The symbols shown in the first to tenth sections represent only one example of resource configuration.

[0156] The following scenario focuses on the first base station performing round-trip measurements of the sensed signal, and in this scenario, the time slot after the uplink sensed symbol is not considered:

[0157] In one embodiment, the sensing signal is transmitted on a flexible time slot adjacent to the full downlink time slot in the third frame structure. Correspondingly, the first frame structure configuration includes: a first downlink communication symbol count, a first flexible symbol count, a first uplink sensing symbol count, a first uplink communication symbol count, and a second downlink sensing symbol count; the second frame structure configuration includes: a second downlink communication symbol count, a first downlink sensing symbol count, a second flexible symbol count, and a second uplink sensing symbol count; wherein, the first flexible symbol count is equal to the difference between the second downlink communication symbol count and the first downlink communication symbol count.

[0158] Here, the sensing signal is transmitted on a flexible time slot adjacent to the full downlink time slot of the third frame structure, that is, the sensing signal is transmitted on a flexible time slot immediately following the full downlink time slot of the third frame structure.

[0159] For example, the first frame structure configuration includes: a first downlink communication symbol count x2(b), x2(b) = 2; a first flexible symbol count x2(a) - x2(b), x2(a) - x2(b) = 1; a first uplink sensing symbol count us2, us2 = 2; a first uplink communication symbol count f2(a), f2(a) = 1; and a second downlink sensing symbol count ds3, ds3 = 2. The second frame structure configuration includes: a second downlink communication symbol count x2(a), x2(a) = 3; a first downlink sensing symbol count ds2, ds2 = 2; a first flexible symbol count f2(a), f2(a) = 1; and a second uplink sensing symbol count us3, us3 = 2. Then, referring to... Figure 10 In the flexible time slot immediately following the full downlink time slot of the third frame structure, for the first base station, the first x2(b) + (x2(a) - x2(b)) symbols of the flexible time slot, that is, the two symbols after the first three symbols of the flexible time slot, are uplink sensing symbols. After these two uplink sensing symbols are f2(a) uplink communication symbols, that is, one uplink communication symbol. After this uplink communication symbol, the two symbols are downlink sensing symbols. For the second base station, the first x2(a) symbols of the flexible time slot, that is, the two symbols after the first three symbols of the flexible time slot, are downlink sensing symbols. After these two uplink sensing symbols are f2(a) flexible symbols, that is, one flexible symbol. After this one flexible symbol, the two symbols are uplink sensing symbols.

[0160] In one embodiment, the sensing signal is transmitted on a flexible time slot adjacent to the full uplink time slot of the third frame structure, and a first configuration is used for the first base station to perform round-trip measurements of the sensing signal; correspondingly,

[0161] The first frame structure configuration includes: the number of first uplink communication symbols; the second frame structure includes: the number of second uplink communication symbols; wherein, the number of first uplink communication symbols is equal to the number of second uplink communication symbols.

[0162] Here, the sensing signal is transmitted on the flexible time slot adjacent to the full uplink time slot of the third frame structure, that is, the sensing signal is transmitted on the flexible time slot immediately preceding the full uplink time slot of the third frame structure.

[0163] For example, the first frame structure configuration includes: a first uplink communication symbol count y2(b), y2(b) = 2; the second frame structure configuration includes: a second uplink communication symbol count y2(a), y2(a) = y2(b). Then, referring to... Figure 11In the flexible time slot adjacent to the full uplink time slot of the third frame structure, for the first base station, all symbols except the last y2(b) symbols of the flexible time slot are treated as flexible symbols and can be used to configure uplink sensing symbols or downlink sensing symbols. For the second base station, all symbols except the last y2(a) symbols of the flexible time slot are treated as flexible symbols and can be used to configure downlink sensing symbols or uplink sensing symbols. It should be noted here that... Figure 11 In this flexible time slot, except for the last two symbols, the first through twelfth symbols are all used as flexible symbols. Figure 11 The symbols 1 through 12 shown are merely one example of resource configuration. In practical applications, resource configuration methods from related technologies can be used, such as RRC signaling and semi-static scheduling. Figure 11 The first to 12th symbols in the code are used for resource configuration, and no restrictions are imposed here.

[0164] Alternatively, in one embodiment, the sensing signal is transmitted on a flexible time slot adjacent to the full uplink time slot of the third frame structure, and the first configuration is used for the first base station to perform round-trip measurements of the sensing signal; correspondingly,

[0165] The first frame structure configuration includes: the number of first uplink communication symbols and the number of first flexible symbols; the second frame structure includes: the number of second uplink communication symbols; wherein, the number of second uplink communication symbols is equal to the sum of the number of first uplink communication symbols and the number of first flexible symbols.

[0166] Here, the sensing signal is transmitted on the flexible time slot adjacent to the full uplink time slot of the third frame structure, that is, the sensing signal is transmitted on the flexible time slot immediately preceding the full uplink time slot of the third frame structure.

[0167] For example, the first frame structure configuration includes: a first uplink communication symbol count y2(b), y2(b) = 2, and a first flexible symbol count f2(b), f2(b) = 2; the second frame structure configuration includes: a second uplink communication symbol count y2(a), y2(a) = 4. Then, referring to... Figure 12 In the flexible time slot adjacent to the full uplink time slot of the third frame structure, for the first base station, all symbols except the last y2(b)+f2(b) symbols of the flexible time slot are treated as flexible symbols and can be used to configure uplink sensing symbols or downlink sensing symbols; for the second base station, the last y2(a) symbols of the flexible time slot, and all other symbols, are treated as flexible symbols and can be used to configure downlink sensing symbols or uplink sensing symbols. It should be noted here that... Figure 12 In this flexible time slot, except for the last four symbols, the first through tenth symbols are all used as flexible symbols. Figure 12The symbols 1 through 10 shown are merely one example of resource configuration. In practical applications, resource configuration methods from related technologies can be used, such as RRC signaling, semi-static scheduling, etc. Figure 12 The first to tenth symbols in the code are used for resource configuration, and no specific restrictions are imposed here.

[0168] The following scenario focuses on the first base station performing round-trip measurements of the sensed signal, and in this scenario, the time slot after the uplink sensed symbol is considered:

[0169] In one embodiment, the sensing signal is transmitted on a flexible time slot adjacent to the full downlink time slot of the third frame structure, and a first configuration is used for round-trip measurement of the sensing signal; correspondingly,

[0170] The first frame structure configuration includes: the number of first downlink communication symbols, the number of first flexible symbols, the number of first uplink sensing symbols, the number of second flexible symbols, the number of first uplink communication symbols, and the number of second downlink sensing symbols; the second frame structure configuration includes: the number of second downlink communication symbols, the number of first downlink sensing symbols, the number of third flexible symbols, and the number of second uplink sensing symbols; wherein,

[0171] The number of first flexible symbols is equal to the difference between the number of second downlink communication symbols and the number of first downlink communication symbols; the number of first uplink communication symbols is the difference between the number of third flexible symbols and the number of second flexible symbols.

[0172] Here, the sensing signal is transmitted on a flexible time slot adjacent to the full downlink time slot of the third frame structure, that is, the sensing signal is transmitted on a flexible time slot immediately following the full downlink time slot of the third frame structure. On this flexible time slot, the number of downlink communication symbols ranges from 0 to 13.

[0173] For example, the first frame structure configuration includes: the number of first downlink communication symbols is x2(b), x2(b) = 2; the number of first flexible symbols is x2(a) - x2(b), x2(a) - x2(b) = 2; the number of first uplink sensing symbols is us2, us2 = 1; the number of second flexible symbols is 1; the number of first uplink communication symbols is 1; and the number of second downlink sensing symbols is ds3, ds3 = 1. The second frame structure configuration includes: the number of second downlink communication symbols is x2(a), x2(a) = 4; the number of first downlink sensing symbols is ds2, ds2 = 1; the number of third flexible symbols is 2; and the number of second uplink sensing symbols is 1. Then, referring to... Figure 13For the second base station, in the flexible time slot immediately following the full downlink time slot of the third frame structure, the ds2 symbols following the x2(a) downlink communication symbols starting from the start symbol of the flexible time slot are downlink sensing symbols, i.e., the 5th symbol is a downlink sensing symbol. The 2 symbols following this downlink sensing symbol are flexible symbols, and the 1 symbol following these 2 flexible symbols is an uplink sensing symbol. For the first base station, in the flexible time slot immediately following the full downlink time slot of the third frame structure, the us2 symbols following the x2(b) downlink communication symbols starting from the start symbol of the flexible time slot are uplink sensing symbols, i.e., the 5th symbol is an uplink sensing symbol. The 1 symbol following this uplink sensing symbol is a flexible symbol, the 1 symbol following this 1 flexible symbol is an uplink communication symbol, and the 1 symbol following this uplink communication symbol is an uplink sensing symbol.

[0174] Thus, it can be seen that, based on the first frame structure configuration and the second frame structure configuration, the sensing signal and the communication signal are compatible, and the sensing signal achieves symbol-level uplink and downlink unified configuration.

[0175] In another embodiment, the sensing signal is transmitted on a flexible time slot adjacent to the full uplink time slot of the third frame structure, and a first configuration is used for round-trip measurement of the sensing signal; correspondingly,

[0176] The first frame structure configuration includes: the number of first uplink communication symbols, and the second frame structure configuration includes: the number of second uplink communication symbols, wherein the number of first uplink communication symbols is equal to the number of second uplink communication symbols.

[0177] Here, the sensing signal is transmitted on the flexible time slot adjacent to the full downlink time slot of the third frame structure, that is, the sensing signal is transmitted on the flexible time slot immediately preceding the full uplink time slot of the third frame structure. On this flexible time slot, the number of uplink communication symbols ranges from 0 to 13.

[0178] For example, in the first frame structure configuration: the number of first uplink communication symbols is y2(b), y2(b) = 1; in the second frame structure configuration, y2(a), y2(a) = 1, y2(b) = y2(a). Then, referring to... Figure 14 In the flexible time slots following the full downlink time slots of the third frame structure, for the first base station, all symbols except the last y2(b) symbols of this flexible time slot are treated as flexible symbols and can be used to configure uplink sensing symbols or downlink sensing symbols. For the second base station, all symbols except the last y2(a) symbols of this flexible time slot are treated as flexible symbols and can be used to configure downlink sensing symbols or uplink sensing symbols. It should be noted here that... Figure 14 In this flexible time slot, except for the last symbol, the first through thirteenth symbols are all used as flexible symbols. Figure 14The symbols 1 through 13 shown are merely one example of resource configuration. In practical applications, resource configuration methods from related technologies can be used, such as RRC signaling and semi-static scheduling. Figure 14 The first to thirteenth symbols in the code are used for resource configuration, and no specific restrictions are imposed here.

[0179] Alternatively, in another embodiment, the first frame structure configuration includes: a first number of uplink communication symbols and a first number of flexible symbols, and the second frame structure includes: a second number of uplink communication symbols, wherein the second number of uplink communication symbols is equal to the sum of the first number of uplink communication symbols and the first number of flexible symbols.

[0180] For example, in the first frame structure configuration: the number of first uplink communication symbols is y2(b), y2(b) = 1, and the number of first flexible symbols is f2(b), f2(b) = 2. In the second frame structure configuration, y2(a), y2(a) = y2(b) + f2(b). Then, referring to... Figure 15 In the flexible time slots following the full downlink time slots of the third frame structure, for the first base station, all symbols except the last y2(b)+f2(b) symbols of this flexible time slot are treated as flexible symbols and can be used to configure uplink sensing symbols or downlink sensing symbols. For the second base station, all symbols except the last y2(a) symbols of this flexible time slot are treated as flexible symbols and can be used to configure downlink sensing symbols or uplink sensing symbols. It should be noted here that... Figure 15 In this flexible time slot, except for the last three symbols, the first through eleventh symbols are all used as flexible symbols. Figure 15 The symbols 1 through 11 shown are merely one example of resource configuration. In practical applications, resource configuration methods from related technologies can be used, such as RRC signaling and semi-static scheduling. Figure 15 The first to eleventh symbols in the code are used for resource configuration, and no specific restrictions are imposed here.
