It can be understood that the above function modules can be network elements in a hardware device, software function modules running on a special hardware, or virtualized function modules instantiated on a platform (for example, a cloud platform).
[0050] In a mobile communication system, there are scenarios that are difficult for a device to perceive, for example, there is an obstruction in the environment around the device, causing the communication signal to be unable to cover the area behind the obstruction, so the device is difficult to perceive the information of objects or environment in the area. Based on this, the embodiments of the present application propose a technical solution of completing perception by means of other devices, that is, one communication device instructs another communication device to perform a perception operation, and the perception of the area that cannot be covered by the communication signal is realized by the cooperation of the two communication devices.
[0051] The embodiments of the present application relate to a first communication device and a second communication device, the first communication device is used to send first information to the second communication device to instruct the second communication device to perform a perception operation, and the second communication device is used to perform the perception operation according to the instruction. Wherein, the first communication device and the second communication device can be network side devices or terminals. The network side device can have various types, including but not limited to at least one of the following: base station, reconfigurable intelligent surface, repeater / relay, satellite, TRP, etc. The terminal can have various types, including but not limited to at least one of the following: user equipment (UE), smart phone, smart watch, helmet, CPE, object with tag, reduced capability / RedCap device, etc.
[0052] The embodiments of the present application do not limit the state of the first communication device and the second communication device, including but not limited to at least one of the following: connected state, idle state, inactive state. In addition, in the following embodiments, one first communication device instructs one second communication device as an example. However, in actual application, one first communication device can instruct one or more second communication devices, or multiple first communication devices can instruct one or more second communication devices, and the principle is the same, which will not be repeated here.
[0053] The perception triggering method and the communication device provided by the embodiments of the present application will be described in detail in combination with the drawings and some embodiments and application scenarios.
[0054] FIG. 2 shows a flowchart of a sensing triggering method according to an embodiment of the present application. The method 200 can be performed by a first communication device. In other words, the method can be performed by software or hardware installed on the first communication device. As shown in FIG. 2, the method can include the following steps.
[0055] S202: The first communication device sends first information to a second communication device, where the first information is used to instruct the second communication device to perform a sensing operation.
[0056] In an embodiment, the first information can include first indication information or first signaling.
[0057] In an embodiment of the present application, the second communication device can be a communication device with sensing capability, which can perform a sensing operation under the instruction of the first information. In some scenarios, if the second communication device is difficult to sense or lacks sensing, the first communication device can reselect another communication device as the second communication device, thereby initiating the instruction to perform sensing.
[0058] In an embodiment of the present application, the sensing operation can be performed in multiple sensing manners, including but not limited to any one of the following manners: active sensing, passive sensing, and interactive sensing. The active sensing refers to sensing by using reflection signals such as echoes of self-transmitted signals, where the transceiver is located at the same position and can use different antennas, and this manner can sense environmental information around the device. The passive sensing refers to sensing by a receiver using wireless signals transmitted by a transmitter, where the transceiver is located at different positions, for example, base station A senses environmental information between base station A and base station B by receiving wireless signals from base station B. The interactive sensing refers to interaction between a sensor and a sensed object, where the subject, time, frequency, format, etc. of electromagnetic wave transmission are agreed upon to assist in the sensing process.
[0059] In an embodiment of the present application, the sensing operation can be a sensing operation for a target area, where the target area is a non-sensing area of the first communication device and a sensing area of the second communication device. The non-sensing area can be an area that the device itself cannot sense, and the sensing area can be an area that the device itself can sense.
[0060] For example, the first communication device is a base station, and there is a high-rise building around the base station. The area behind the building cannot be covered by the communication signal of the base station, and thus is a non-sensing area of the base station. If a terminal can sense the area, the area is a sensing area of the terminal.
[0061] It should be noted that the parameters contained in the sensing resources used by the second communication device when performing the sensing operation can be sent by the first communication device or can be pre-configured by the network side, and the specific configuration is not limited.
[0062] In the embodiment of the present application, the step S202 can further include: selecting the second communication device according to the auxiliary information by the first communication device. The auxiliary information includes at least one of the following: timing advance (TA), location information, measurement result of a preset reference signal of the second communication device, and capability reported by the second communication device.
[0063] For example, there are terminal A and terminal B around the first communication device, and the measurement result of the preset reference signal of terminal B is higher than that of terminal A. Then, the first communication device can select terminal B as the second communication device, and initiate the indication.
[0064] In the embodiment of the present application, the first information can be indicated in different ways in different scenarios, which include but are not limited to any one of the following:
[0065] The first scenario: the first communication device is a network side device, the second communication device is a terminal, and the first information is used to activate or trigger the second communication device to perform the sensing operation.
[0066] The second scenario: the first communication device and the second communication device are both network side devices, and the first information is used to request, suggest or trigger the second communication device to perform the sensing operation.
[0067] The third scenario: the first communication device and the second communication device are both terminals, and the first information is used to request or suggest the second communication device to perform the sensing operation.
[0068] The fourth scenario: the first communication device is a terminal, the second communication device is a network side device, and the first information is used to request or suggest the second communication device to perform the sensing operation.
[0069] In the embodiment of the present application, the activated corresponding sensing operation can be a periodic sensing operation, and the triggered corresponding sensing operation can be a one-off sensing operation. After the request or suggestion is initiated, the second communication device can accept the request or suggestion, or can not accept the request or suggestion, which is not limited in the embodiment.
[0070] In one implementation, the step S202 can further include: receiving the sensing result sent by the second communication device by the first communication device; or, receiving the periodically sent sensing result by the first communication device. This scenario belongs to the scenario that the second communication device can complete the sensing and send the sensing result to the first communication device. In actual application, there can also be a scenario that the second communication device does not send the sensing result, for example, the second communication device refuses to perform the sensing operation or cannot complete the sensing operation due to moving out of the sensing area. Then, the first communication device can re-initiate the process of selecting a new second communication device and giving the sensing indication, which is not described here.
[0071] In addition, it is worth mentioning that in the scenario where the second communication device performs the sensing operation but does not return the sensing result, although the first communication device does not receive the sensing result, the second communication device can use the sensing result to improve its own communication quality, for example, the second communication device can determine the communication parameters such as the beam or precoding vector used according to the sensing result, so as to improve the communication quality of the second communication device through the first communication device instructing the second communication device to perform the sensing operation.
[0072] In another implementation, the step S202 can further include that the first communication device sends second information to the second communication device, and the second information is used to instruct the second communication device to stop the sensing operation. In an implementation, the second information can include second indication information or second signaling. Exemplarily, the first communication device is a network side device, the second communication device is a terminal, and the second information is used to deactivate the sensing operation of the second communication device.
[0073] In an implementation, the first information is also used to instruct the second communication device to receive the sensing signal. Correspondingly, the method can further include that the first communication device sends third information to a third communication device, and the third information is used to instruct the third communication device to send the sensing signal.
[0074] Among them, the scenarios involving the third communication device can be various, including but not limited to any one of the following:
[0075] The second communication device and the third communication device are both terminals; or,
[0076] The second communication device is a terminal, and the third communication device is a network side device; or,
[0077] The second communication device is a network side device, and the third communication device is a terminal; or,
[0078] The second communication device and the third communication device are both network side devices.
[0079] In the embodiments of the present application, the first information can include preset direction information or omnidirectional information, the preset direction information includes: a Transmission Configuration Indication (TCI) state number or an ordering direction of the TCI state number. Among them, the TCI state number is used to instruct to perform the sensing operation according to the corresponding direction, the ordering direction is used to instruct to determine the direction corresponding to the next TCI state number according to the ordering direction and perform the sensing operation according to the direction, and the omnidirectional information is used to instruct to perform the omnidirectional sensing operation according to the counterclockwise direction or the clockwise direction.
[0080] The method provided in the embodiments of the present application can further include the following steps before or after the step S202: the first communication device sends fourth information to the second communication device, and the fourth information is used to inform the second communication device to perform the sensing operation or stop the sensing operation. The notification can be a one-time action or a periodic action, and the specific implementation is not limited.
[0081] The first communication device can send the fourth information in multiple scenarios, including but not limited to any one of the following scenarios:
[0082] The first communication device is a network-side device, and the second communication device is a terminal; or
[0083] The first communication device and the second communication device are both network-side devices; or
[0084] The first communication device is a terminal, and the second communication device is a network-side device.
[0085] The method provided in the embodiments of the present application can be used to send the first information from the first communication device to the second communication device, and the first information is used to instruct the second communication device to perform the sensing operation. For a scenario that is difficult for the first communication device to sense, the first communication device can trigger the second communication device to assist it to complete the sensing. For a scenario that lacks sensing of the second communication device, the triggering of the first communication device can make the second communication device perform the sensing operation. Whether it is a difficult-to-sense scenario or a lack-of-sensing scenario, a solution is provided.
[0086] FIG. 3 shows a flowchart of a sensing triggering method provided in the embodiments of the present application, and the method 300 can be performed by a first communication device. As shown in FIG. 3, the method can include the following steps.
[0087] S302: The first communication device sends first information to the second communication device, and the first information is used to instruct the second communication device to perform the sensing operation.
[0088] In an implementation, the first information can include first indication information or first signaling.
[0089] In the embodiments of the present application, the first communication device can select the second communication device according to the assistance information. The assistance information can be in multiple forms, including but not limited to at least one of the following forms: timing advance (TA), location information, a measurement result of a preset reference signal of the second communication device, and a capability reported by the second communication device.
[0090] In an implementation, the sensing operation can be a sensing operation for a target area, and the target area is a non-sensing area of the first communication device and a sensing area of the second communication device.
[0091] S304: The first communication device receives the sensing result sent by the second communication device, or receives the sensing result periodically sent by the second communication device.
[0092] The second communication device can perform a one-time sensing operation after receiving the indication of the first communication device, or can also perform a periodic sensing operation. In the case of performing a periodic sensing operation, the second communication device can send the sensing result to the first communication device after each time of performing the sensing operation, or can also send all the sensing results to the first communication device together after performing the sensing operation multiple times, and the embodiment does not make specific limitation on this.
[0093] S306: The first communication device sends second information to the second communication device, and the second information is used to instruct the second communication device to stop the sensing operation.
[0094] In an implementation, the second information can include second indication information or second signaling.
[0095] In an implementation, the first communication device is a network side device, and the second communication device is a terminal. The above step S306 can specifically include: the first communication device sends second information to the second communication device, and the second information is used to deactivate the sensing operation of the second communication device.
[0096] For example, the base station instructs the UE to perform the sensing operation on the target area due to the existence of an obstacle. When the base station finds that the UE moves and may not be able to sense the target area, the base station can instruct the UE to stop performing the sensing operation on the target area.
[0097] The above method provided by the embodiment of the application, by the first communication device sending the first information to instruct the second communication device to perform the sensing operation, receiving the sensing result sent by the second communication device, and sending the second information to instruct the second communication device to stop the sensing operation, not only realizes triggering the second communication device to assist the first communication device to complete the sensing operation, but also realizes triggering the second communication device to stop the sensing operation, and the control is more flexible and efficient.
[0098] FIG. 4 shows a flowchart of a sensing triggering method provided by an embodiment of the application. The method 400 can be performed by a first communication device. As shown in FIG. 4, the method can include the following steps.
[0099] S402: The first communication device sends first information to the second communication device, and the first information is used to instruct the second communication device to receive a sensing signal and perform a sensing operation.
[0100] In an implementation, the first information can include first indication information or first signaling.
[0101] S404: The first communication device sends third information to the third communication device, where the third information is used to instruct the third communication device to send the sensing signal.
[0102] In the embodiments of the present application, the first communication device can select the third communication device according to the auxiliary information. The auxiliary information includes, but is not limited to, at least one of the following: TA, Reference Signal Received Power (RSRP), etc. For example, the first communication device can select a device with TA within the indicated range, or a device with RSRP greater than a specified threshold, as the third communication device, which is not described in detail here.
[0103] In the embodiments of the present application, the role of the third communication device is to send the sensing signal, while the second communication device undertakes the main work of sensing, not only receiving the sensing signal but also performing the sensing operation, and thus obtaining the sensing result. This way of cooperating with the second communication device and the third communication device to complete the sensing operation together can be called a Bistatic sensing mode, and there can be many applicable scenarios, including but not limited to any of the following:
[0104] The first scenario: the second communication device and the third communication device are both terminals.
[0105] The second scenario: the second communication device is a terminal, and the third communication device is a network side device.
[0106] The third scenario: the second communication device is a network side device, and the third communication device is a terminal.
[0107] The fourth scenario: the second communication device and the third communication device are both network side devices.
[0108] In the embodiments of the present application, sending and receiving the sensing signal can also be completed by one device itself, and this sensing mode can be called a Monostatic sensing mode, and the applicable scenarios include but are not limited to any of the following: a network side device transmits and receives the sensing signal, or a terminal transmits and receives the sensing signal.
[0109] In the embodiments of the present application, due to the limitation of the capability of the second communication device, there can be a case where the second communication device can both send and receive the sensing signal, and there can also be a case where the second communication device can only receive the sensing signal but cannot send the sensing signal. For the first case, the second communication device can independently complete the sensing operation, i.e., the Monostatic sensing mode. For the second case, the first communication device will select the third communication device and instruct it to send the sensing signal, so as to be able to cooperate with the second communication device to complete the sensing operation, i.e., the Bistatic sensing mode.
[0110] For example, the second communication device is a base station, and has the capability of sending and receiving sensing signals, the first communication device does not need to select and instruct the third communication device to assist in completing sensing, and the sensing operation is completed by the second communication device independently. For another example, the second communication device is a terminal, and has the capability of receiving sensing signals, but does not have the capability of sending sensing signals, the first communication device needs to select the third communication device, such as a base station, and instruct it to send sensing signals, so that the terminal can complete the sensing operation in cooperation.
[0111] FIG. 5 shows a schematic diagram of a double-base sensing scenario provided by the embodiment of the present application. In FIG. 5a, the second communication device and the third communication device are both terminals, the terminal on the left side, that is, the third communication device, sends sensing signals, and the terminal on the right side, that is, the second communication device, receives sensing signals. In FIG. 5b, the second communication device is a terminal, and the third communication device is a network-side device, the network-side device on the left side, that is, the third communication device, sends sensing signals, and the terminal on the right side, that is, the second communication device, receives sensing signals. In FIG. 5c, the second communication device is a network-side device, and the third communication device is a terminal, the terminal on the left side, that is, the third communication device, sends sensing signals, and the network-side device on the right side, that is, the second communication device, receives sensing signals. In FIG. 5d, the second communication device and the third communication device are both network-side devices, the network-side device on the left side, that is, the third communication device, sends sensing signals, and the network-side device on the right side, that is, the second communication device, receives sensing signals.
[0112] FIG. 6 shows a schematic diagram of a single-base sensing scenario provided by the embodiment of the present application. In FIG. 6a, the network-side device itself sends sensing signals and receives sensing signals, and in FIG. 6b, the terminal itself sends sensing signals and receives sensing signals.
[0113] In the embodiment of the present application, whether it is a double-base sensing mode or a single-base sensing mode, a suitable mode can be selected according to an actual scenario, for example, a plurality of factors such as whether there is an obstruction around, the distance between devices, or the capability of the device, and the embodiment is not limited in this regard.
[0114] The above method provided by the embodiment of the present application is that the first communication device instructs the second communication device to receive sensing signals and perform sensing operations by sending first information, and instructs the third communication device to send sensing signals by sending third information, which realizes a solution of giving an instruction by one device and receiving and sending sensing signals by the other two devices, and can be applied to a scenario in which one device cannot complete sensing itself. In addition, the embodiment of the present application also provides a single-base sensing solution, which can be applied to a scenario in which one device can complete sensing itself.
[0115] FIG. 7 shows a flow diagram of a method for triggering sensing according to an embodiment of the present application. The method 700 can be performed by a second communication device. As shown in FIG. 7, the method can include the following steps.
[0116] At S702, the second communication device receives first information sent by the first communication device, the first information being used to instruct the second communication device to perform a sensing operation.
[0117] In an embodiment, the first information can include first indication information or first signaling.
[0118] In an embodiment of the present application, the sensing operation can be a sensing operation for a target area, the target area being a non-sensing area of the first communication device and a sensing area of the second communication device.
[0119] In an embodiment, the first information can be used to suggest the second communication device to perform the sensing operation. Accordingly, the method can further include, after S702, that the second communication device performs the sensing operation and sends a sensing result to the first communication device, or the second communication device refuses to perform the sensing operation.
[0120] In an embodiment, after receiving the first information, the second communication device can accept the suggestion of the first communication device, i.e., perform the sensing operation and send the sensing result, or the second communication device can not accept the suggestion of the first communication device, i.e., refuse to perform the sensing operation. The second communication device can select one of the two ways according to needs, and the present embodiment does not limit the selection.
[0121] For example, if the current state of the second communication device is suitable for sensing, the second communication device can accept the suggestion of the first communication device. If the second communication device is about to leave the sensing area and cannot complete the sensing or will affect the sensing accuracy, the second communication device can refuse the suggestion of the first communication device.
[0122] The method provided by the embodiments of the present application can be used to receive, by a second communication device, first information sent by a first communication device, the first information being used to instruct the second communication device to perform a sensing operation. For a scene difficult for the first communication device to sense, the first communication device can trigger the second communication device to assist the first communication device to complete the sensing. For a scene lacking sensing by the second communication device, the second communication device can be triggered by the first communication device to perform the sensing operation. Solutions are provided for both the scene difficult to sense and the scene lacking sensing.
[0123] FIG. 8 shows a flow diagram of a method for triggering sensing according to an embodiment of the present application. The method 800 can be performed by a second communication device. As shown in FIG. 8, the method can include the following steps.
[0124] S802: The second communication device receives first information sent by the first communication device, and the first information is used to instruct the second communication device to perform a sensing operation.
[0125] In an implementation, the first information can include first indication information or first signaling.
[0126] S804: The second communication device performs the sensing operation and sends a sensing result to the first communication device.
[0127] In an implementation, the first information can be used to activate, request or suggest the second communication device to perform the sensing operation. Accordingly, the step S804 can specifically include that the second communication device periodically performs the sensing operation and sends the sensing result to the first communication device.

Not only the second communication device assists the first communication device to complete the sensing operation, but also the first information and the second information can be used to control the second communication device to start the sensing operation and stop the sensing operation, and the control is more flexible and efficient.
[0133] FIG. 9 shows a flow diagram of a sensing triggering method provided by the embodiments of the present application, and the method 900 can be performed by the second communication device. As shown in FIG. 9, the method can include the following steps.
[0134] S902: The second communication device receives first information sent by the first communication device, and the first information is used to instruct the second communication device to receive a sensing signal and perform a sensing operation.
[0135] In an implementation, the first information can include first indication information or first signaling.
[0136] S904: The second communication device receives the sensing signal sent by the third communication device, generates a sensing result according to the sensing signal, and sends the sensing result to the first communication device.
[0137] The third communication device is a device indicated by the first communication device for sending the sensing signal.
[0138] In the embodiments of the present application, the sensing operation is completed by the second communication device and the third communication device in cooperation, that is, the dual-base sensing mode. The applicable scenarios can be various, including but not limited to any one of the following:
[0139] The first scenario: the second communication device and the third communication device are both terminals.
[0140] The second scenario: the second communication device is a terminal, and the third communication device is a network side device.
[0141] The third scenario: the second communication device is a network side device, and the third communication device is a terminal.
[0142] The fourth scenario: the second communication device and the third communication device are both network side devices.
[0143] Of course, in addition to the above-mentioned dual-base sensing mode, the embodiments of the present application can also adopt a single-base sensing mode, that is, the sending and receiving of the sensing signal are both completed by the same device. The applicable scenarios include but are not limited to any one of the following: a network side device transmits and receives the sensing signal, or a terminal transmits and receives the sensing signal. Whether it is a dual-base sensing mode or a single-base sensing mode, a suitable mode can be selected according to the actual scenario, such as referring to whether there is an obstruction around, the distance or the ability of the device, and other factors. The embodiments do not make specific limitations.
[0144] The above-mentioned method provided by the embodiments of the present application, after the second communication device receives the first information sent by the first communication device, receives the sensing signal sent by the third communication device and performs the sensing operation, generates the sensing result and sends it to the first communication device, realizes the solution of giving an indication by one device and transmitting and receiving the sensing signal by the other two devices, which can be applicable to the scenario that one device cannot complete the sensing itself. In addition, the embodiments of the present application also provide a single-base sensing solution, which can be applicable to the scenario that one device can complete the sensing itself.
[0145] FIG. 10 shows a flowchart of a sensing triggering method provided by the embodiments of the present application. The method 1000 can be executed by the second communication device. As shown in FIG. 10, the method can include the following steps.
[0146] S1002: The second communication device receives first information sent by the first communication device, the first information being used to instruct the second communication device to perform a sensing operation, and the first information including preset direction information or omnidirectional information.
[0147] In the embodiments of the present application, the first information can include first indication information or first signaling. The preset direction information includes a TCI state number or a sorting direction of the TCI state number.
[0148] The TCI state number is used to indicate that the sensing operation is performed in a corresponding direction. The sorting direction is used to indicate that the direction corresponding to the next TCI state number is determined according to the sorting direction, and the sensing operation is performed in the direction. The omnidirectional information is used to indicate that the omnidirectional sensing operation is performed in a counterclockwise direction or a clockwise direction.
[0149] In the embodiments of the present application, the TCI state number has a one-to-one correspondence with the direction. If the first information includes the TCI state number, the direction corresponding to the TCI state number can be determined according to the TCI state number, and then the sensing operation can be performed in the direction.
[0150] In the case where there are multiple TCI state numbers, the TCI state numbers can be sorted in ascending order or descending order according to the size of the numbers. If the first information includes the sorting direction of the TCI state number, i.e., the ascending direction or the descending direction, the direction corresponding to the next TCI state number can be determined according to the sorting direction, and then the sensing operation can be performed in the direction. In this case, the sensing direction can be obtained without carrying the TCI state number in the first information, which can save resource overhead and improve transmission efficiency.
[0151] For example, the TCI state numbers are sorted in ascending order as follows: TCI state number 1, TCI state number 2, and TCI state number 3, corresponding to direction 1, direction 2, and direction 3, respectively. If the TCI state number is specified in the ascending order in the first information, the sensing direction is direction 1 if the second communication device performs sensing for the first time, the sensing direction is direction 2 if the second communication device performs sensing for the second time, and the sensing direction is direction 3 if the second communication device performs sensing for the third time, so that the direction of each sensing can be directly determined, and the first communication device does not need to notify the direction of each sensing operation, which is high in sensing efficiency and saves overhead, and is suitable for a periodic sensing method and easy to avoid interference with communication signals.
[0152] S1004: The second communication device performs the sensing operation according to the preset direction information or the omnidirectional information.
[0153] In the embodiments of the present application, the omnidirectional information corresponds to two scenarios, one is counterclockwise direction perception, and the other is clockwise direction perception. The second communication device can perform the perception operation according to the omnidirectional information in the counterclockwise direction or in the clockwise direction, and the embodiments do not make specific limitations on this.
[0154] Whether it is counterclockwise or clockwise, the second communication device performing omnidirectional perception operation can include multiple perception actions, rotating a fixed angle every fixed time, until completing 360° direction perception. For example, the second communication device can rotate 15° every 5ms in the counterclockwise direction or in the clockwise direction, until rotating a full circle to complete 360° direction perception. In this way, the second communication device can directly determine the direction of each perception, without the first communication device informing the direction of each perception operation, the perception efficiency is high, the overhead is saved, and it is suitable for periodic perception method, and easy to avoid interference with communication signals.
[0155] S1006: The second communication device sends the perception result to the first communication device.
[0156] The perception result obtained by the second communication device includes the perception result of the preset direction or the omnidirectional perception result. If the preset direction perception operation is performed and it is periodic perception, the perception result of this time can be sent to the first communication device after each perception operation is performed, or the multiple perception results can be sent to the first communication device after multiple perception operations are performed, and the embodiments do not make specific limitations on this.
[0157] FIG. 11 shows a scene diagram of the preset direction perception and the omnidirectional perception provided by the embodiments of the present application. FIG. 11a is a preset direction perception scene, and the first communication device can initiate three indications carrying TCI state number 1, TCI state number 2 and TCI state number 3 respectively. After receiving the first information, the second communication device can determine the corresponding direction according to the TCI state number currently carried in the first information, and then complete the perception operation according to the direction. The second communication device can complete three times of perception operation in the corresponding direction according to the three received TCI state numbers. FIG. 11b is an omnidirectional perception scene, and the first communication device can carry omnidirectional information in the first information. After receiving the indication, the second communication device can perform omnidirectional perception operation in the counterclockwise direction or in the clockwise direction. The first information can also carry a TCI state number to determine the starting perception direction, and the second communication device can start 360° perception operation from the starting perception direction.
[0158] The above method provided by the embodiments of the present application, after the second communication device receives the first information sent by the first communication device, the second communication device performs the sensing operation according to the preset direction information or the omnidirectional information in the first information, and sends the sensing result to the first communication device, so that the second communication device completes the sensing operation according to the indicated direction, and the sensing accuracy and the accuracy of sensing control can be improved. Moreover, for a scene that is difficult for the first communication device to sense, the first communication device can trigger the second communication device to assist it to complete the sensing, and for a scene that lacks sensing of the second communication device, the second communication device can be triggered by the first communication device to perform the sensing operation, and a solution is provided for both the scene that is difficult to sense and the scene that lacks sensing.
[0159] FIG. 12 shows a flowchart of a sensing triggering method provided by the embodiments of the present application, the method 1200 can be executed by the second communication device, wherein the first communication device can be a network side device, and the second communication device can be a terminal. As shown in FIG. 12, the method can include the following steps.
[0160] S1202: The second communication device receives fourth information sent by the first communication device, the fourth information is used to inform the second communication device to perform the sensing operation or stop the sensing operation by the first communication device, and the sensing resource of the first communication device overlaps with the communication resource of the second communication device.
[0161] S1204: In the case that the fourth information is used to inform the second communication device to perform the sensing operation by the first communication device, the second communication device determines that the first communication device starts to perform the sensing operation after a preset time length, and stops the receiving operation in the communication resource.
[0162] In the embodiments of the present application, the sensing resource of the first communication device overlaps with the communication resource of the second communication device, including partial overlap or complete overlap. The resources involved include but are not limited to at least one of the following: time domain resource, frequency domain resource or space domain resource. Whether it is partial overlap or complete overlap, it represents that there is resource conflict, therefore, the second communication device can perform corresponding actions to avoid signal interference.
[0163] The above step S1204 belongs to the scene that the first communication device performs the sensing operation, therefore, the second communication device can stop the receiving operation in the communication resource in the process of sensing of the first communication device, so as to avoid the occurrence of data loss due to signal interference.
[0164] S1206: In the case that the fourth information is used to inform the second communication device to stop the sensing operation by the first communication device, the second communication device determines that the first communication device starts to stop the sensing operation after a preset time length, and starts to perform the receiving operation in the communication resource.
[0165] The step S1206 belongs to a scenario that the first communication device performs a stop sensing operation, for example, the first communication device has completed sensing and informs the second communication device through the fourth information. In this scenario, no resource conflict will be generated, and therefore, the second communication device can start performing the receiving operation on the communication resource after the first communication device stops the sensing operation, thereby resuming data communication.
[0166] In the embodiments of the present application, the preset time length can be pre-configured by the network side device or the terminal and notified to the opposite party, and the preset time length represents a time interval between receiving the fourth information and starting or stopping the sensing operation. The second communication device can determine when to perform the subsequent action according to the preset time length.
[0167] FIG. 13 shows a diagram of sensing resource and communication resource conflict provided by the embodiments of the present application. Referring to FIG. 13, the sensing resource of node A (such as a base station) partially overlaps with the communication resource of device B (such as a terminal), for example, the frequency domain resource overlaps. Taking the case that node A informs device B that node A is about to perform a sensing operation or stop the sensing operation as an example. The scenario of FIG. 13a is that node A informs device B that node A is about to perform a sensing operation. After device B receives the notification message, it is determined that node A starts to perform the sensing operation after the preset time length, and therefore, device B stops performing the receiving operation on the communication resource after the preset time length. The sensing operation of node A can be a periodic sensing operation, for example, the sensing operation is performed once in each sensing period. Correspondingly, device B can stop performing the receiving operation on the communication resource each time node A starts to perform the sensing operation, thereby avoiding resource conflict. The scenario of FIG. 13b is that node A informs device B that node A is about to stop the sensing operation. After device B receives the notification message, it is determined that node A starts to stop the sensing operation after the preset time length, and therefore, device B starts to perform the receiving operation on the communication resource after the preset time length. The sensing operation of node A can be a periodic sensing operation, for example, the sensing operation is performed once in each sensing period. Correspondingly, device B can start to perform the receiving operation on the communication resource each time node A stops performing the sensing operation, thereby avoiding resource conflict.
[0168] The method provided in the embodiments of the present application can make the second communication device learn the occupation or release of the sensing resource of the first communication device in time, because the sensing resource of the first communication device overlaps with the communication resource of the second communication device. Therefore, the second communication device determines that the first communication device starts to perform the sensing operation after a preset time length, and stops performing the receiving operation on the communication resource, and determines that the first communication device starts to stop the sensing operation after the preset time length, and starts to perform the receiving operation on the communication resource, thereby avoiding the interference of the normal communication in the sensing area, preventing the resource conflict, releasing the sensing resource for the normal communication service transmission in time, and further achieving the effect of better assisting the communication and improving the communication performance.
[0169] FIG. 14 shows a flow diagram of a sensing triggering method provided in the embodiments of the present application. The method 1400 can be performed by the second communication device. The first communication device can be a terminal, and the second communication device can be a network side device. As shown in FIG. 14, the method can include the following steps.
[0170] S1402: The second communication device receives fourth information sent by the first communication device. The fourth information is used to inform the second communication device to perform the sensing operation by the first communication device. The sensing resource of the first communication device overlaps with the communication resource of the second communication device.
[0171] In the embodiments of the present application, the sensing resource of the first communication device overlaps with the communication resource of the second communication device, including partial overlap or complete overlap. The resource involved includes but is not limited to at least one of the following: time domain resource, frequency domain resource or space domain resource. Whether it is partial overlap or complete overlap, it represents that there is a resource conflict, and therefore the second communication device can perform corresponding scheduling to avoid signal interference.
[0172] S1404: The second communication device determines that the first communication device starts to perform the sensing operation after a preset time length, and schedules the non-overlapping communication resource or does not schedule the overlapping communication resource for communication.
[0173] For example, the space domain resource of the first communication device is beam A, which overlaps with the space domain resource of the second communication device. Therefore, the second communication device can use the non-overlapping space domain resource beam C to communicate, or can also not schedule the overlapping beam A to communicate. It should be noted that the beam overlap in the embodiments of the present application means that the two beams have strong interference, and are not orthogonal or quasi-orthogonal.
[0174] In the embodiments of the present application, the preset time length can be preconfigured by the first communication device or the second communication device and notified to the other party, the preset time length represents a time interval between receiving the fourth information and starting the sensing operation, and the second communication device can determine when to perform the subsequent action according to the preset time length.
[0175] In an implementation, in the case where the overlapping resource is a spatial domain resource, the non-overlapping communication resource scheduled by the second communication device can be orthogonal spatial domain resources.
[0176] FIG. 15 shows a schematic diagram of the conflict between the sensing resource and the communication resource according to an embodiment of the present application. Referring to FIG. 15, the sensing resource of device A (such as a terminal) partially overlaps with the communication resource of node B (such as a base station), for example, the spatial domain resources overlap. Taking the case where device A notifies node B that device A is about to perform a sensing operation as an example. After receiving the notification message, node B determines that device A starts to perform the sensing operation after a preset time length, and therefore, node B schedules non-overlapping communication resources or does not schedule overlapping communication resources for communication after the preset time length. The sensing operation of device A can be a periodic sensing operation, as shown in the figure, device A performs the sensing operation using beam A in the first sensing period, and device A performs the sensing operation using beam B in the second sensing period. Correspondingly, node B can schedule the current non-overlapping beam C for communication or not schedule the current overlapping beam A for communication when device A starts to perform the sensing operation for the first time. Node B can schedule the current non-overlapping beam D for communication or not schedule the current overlapping beam B for communication when device A starts to perform the sensing operation for the second time, thereby avoiding interference to device A. The beam C is orthogonal to the beam A, and the beam D is orthogonal to the beam B, which can ensure that the resource conflict is avoided.
[0177] The above method provided by the embodiments of the present application can receive the fourth information sent by the first communication device by the second communication device, the fourth information is used to notify the second communication device to perform the sensing operation by the first communication device, the sensing resource of the first communication device overlaps with the communication resource of the second communication device, the second communication device determines that the first communication device starts to perform the sensing operation after a preset time length, and then schedules the non-overlapping communication resource or does not schedule the overlapping communication resource for communication, thereby avoiding signal interference and preventing resource conflict.
[0178] The above various method embodiments provided by the present application give a flexible method for the first communication device to activate, deactivate, request, suggest or trigger the second communication device to perform or stop the sensing operation, which can adapt to different scenarios, especially can realize coordination with the communication signal and avoid interference between the sensing and the communication signal, which is very beneficial to the sensing integration.
