[0062] The next-generation network (for example, a 6G network) is expected to be a combination of a mobile communication network, a perception network, and a computing power network. In a narrow sense, the perception network refers to a system with the capabilities of target positioning (distance measurement, speed measurement, angle measurement), target imaging, target detection, target tracking, and target identification.

From the perspective of perception applications, perception can include the following categories:
[0063] · Outdoor / wide-area / local-area applications: including smart cities (for example, weather monitoring, etc.), smart transportation / high-speed rail (for example, high-precision map construction, road supervision, intrusion detection, etc.), low-altitude applications (for example, unmanned aerial vehicle monitoring and obstacle avoidance, flight intrusion detection, flight path management, etc.), and the like;

[0065] The above is only exemplary, and provides some categories of perception applications. The application range of perception is not limited to the above examples.
[0066] Wireless communication and sensing are two important applications of modern radio frequency technology. Sensing uses radio waves to detect parameters of the physical environment to achieve environmental sensing such as target positioning, action recognition, and target imaging. Traditional sensing and wireless communication exist independently, and the separate design wastes wireless spectrum and hardware resources. In the B5G and 6G era, communication spectrum moves to millimeter wave, terahertz, and visible light communication. In the future, the spectrum of wireless communication will coincide with the traditional sensing spectrum. The communication-sensing integrated technology integrates wireless communication and sensing functions, which can use wireless resources to achieve sensing functions, use widely deployed cellular networks to achieve larger range sensing services, use base stations and multiple terminals for joint sensing to achieve higher sensing accuracy, and reuse wireless communication hardware modules to achieve sensing functions and reduce costs. In summary, the communication-sensing integrated technology enables future wireless communication systems to have sensing capabilities, providing a foundation for the development of future smart transportation, smart cities, smart factories, and unmanned aerial vehicles.
[0067] FIG. 2 shows a schematic diagram of sensing modes provided by the related art, including the following eight sensing modes: (1) base station self-initiated self-reception sensing: the base station transmits a sensing signal, and the sensing target transmits a reflection signal after receiving the sensing signal; (2) terminal self-initiated self-reception sensing: the terminal transmits a sensing signal, and the sensing target transmits a reflection signal after receiving the sensing signal; (3) base station cooperative sensing: base station A transmits a sensing signal, and the sensing target transmits a reflection signal to base station B after receiving the sensing signal; (4) terminal cooperative sensing: terminal A transmits a sensing signal, and the sensing target transmits a reflection signal to terminal B after receiving the sensing signal; (5) base station-terminal cooperative sensing: the base station transmits a sensing signal, and the sensing target transmits a reflection signal to the terminal after receiving the sensing signal; (6) terminal-base station cooperative sensing: the terminal transmits a sensing signal, and the sensing target transmits a reflection signal to the base station after receiving the sensing signal; (7) sensing signal transmitting node as the sensing target: the terminal transmits a sensing signal, and the base station is the sensing target; (8) sensing signal receiving node as the sensing target: the base station transmits a sensing signal, and the terminal transmits a feedback after receiving the sensing signal, and the terminal is the sensing target.
[0068] The perception signal sending node and the perception signal receiving node can be collectively referred to as a perception node. In the above eight perception modes, there is only a single or a pair of perception nodes. In a wireless communication system, the number of terminals (mobile phones, IoT devices, etc.) is large. When there are multiple perception nodes (i.e., base stations, mobile phones, IoT devices, etc. that can send and / or receive perception signals) around a perceived terminal, multiple perception nodes jointly participating in perception can improve the accuracy of perception and meet more complex perception service requirements to provide richer perception services. When there are multiple perception nodes in the system, a perception control node can be present to control and manage the entire perception service to improve efficiency. The perception control node can be a base station, a terminal, or a core network element.
[0069] FIG. 3 shows a schematic diagram of multiple perception nodes participating in perception according to an example embodiment of the present application. Taking a vehicle-mounted device as a perceived terminal 31 and a terminal or a base station as a perception control node 32 as an example, the perception control node 32 can send a communication signal to the perception node 1 and the perceived terminal 31, and the perception node 1, the perception node 2, and the perception node 3 can send a perception signal to the perceived terminal 31, so that multiple perception nodes jointly participate in perception, improve the accuracy of perception, meet more complex perception service requirements, and provide richer perception services.
[0070] The perception signal power received by the perceived terminal 31 is closely related to the perception signal transmission power, the signal propagation path, and the reflection coefficient of the perception target. If the perception signal power received by the perceived terminal 31 is too low, it will directly affect the perception result. At the same time, the perception signal and the communication signal or other perception signals can share the same time-frequency resource. In this case, the perception signal can interfere with the communication signal. Therefore, the transmission power of the perception signal is an important factor to be considered, which needs to ensure the accuracy of the perception result and avoid interference with the communication signal or other perception signals as much as possible.
[0071] In related technologies, a base station can set a target receiving power for receiving a perception signal according to a requirement to ensure the reception success rate or decoding success rate of the perception signal. A terminal device adjusts the transmission power of the perception signal according to the target receiving power, so that the perception signal power is close to the target receiving power when the perception signal reaches the base station. Further, the base station can instruct the terminal device to adjust the transmission power of the perception signal in real time through downlink control information (DCI), which can better ensure the reception success rate of the perception signal.
[0072] However, the method for determining the transmission power provided in the related art can only be applied to the uplink transmission process in which the terminal device transmits the sensing signal to the base station, and cannot be applied to other types of transmission processes. Based on this, in order to ensure the success rate of receiving the sensing signal in different types of transmission processes, the embodiments of the present application provide a method for determining the transmission power. FIG. 4 shows a flowchart of the method for determining the transmission power provided in an exemplary embodiment of the present application, which is performed by a first sensing node, and the method comprises:
[0073] Step 420: determining the transmission power of the sensing signal based on the first information.

[0077] Optionally, the sensing target comprises at least one of a car, a person, an environment, a tangible entity, and an intangible entity.
[0078] In the case of different sensing targets, the transmission power of the sensing signal is determined according to different sensing targets, which is beneficial to better adapt to the sensing needs of different sensing targets, and sets the corresponding transmission power for each sensing target while ensuring the sensing performance, which is beneficial to save power consumption.

The sensing position comprises at least one of a first position of the sending node, a second position of the sensing target, and a third position of the receiving node of the sensing signal.
[0080] According to different sensing measurements, the sending power of the sensing signal is determined, which is beneficial to timely adjust the sending power of the sensing signal according to the sensing measurement, so as to ensure that the sending power of the sensing signal is adapted to the sensing measurement, and ensure the sensing performance.
[0081] In some embodiments, the first information comprises a beam direction in the sensing process. Optionally, the beam direction comprises a first beam direction for sending the sensing signal and / or a second beam direction for receiving the sensing signal.
[0082] According to the beam direction, the sending power of the sensing signal is determined, which is beneficial to adapt the sending power of the sensing signal to the beam direction, so as to ensure the sensing performance under different beam directions.
[0083] In some embodiments, the first information further comprises open-loop power control information. Optionally, the open-loop power control information comprises at least one of a target receiving power, a path loss adjustment coefficient, a path loss, and a maximum sending power. The target receiving power refers to the power that the receiving node of the sensing signal expects to receive the sensing signal. The path loss refers to the power loss of the sensing signal in the transmission process. The maximum sending power is used to limit the maximum value of the sending power of the sensing signal.
[0084] In some embodiments, the first information further comprises closed loop power control information. Optionally, the closed loop power control information comprises at least one of a closed loop power adjustment step, a number of adjustment steps, and a power adjustment indication. The closed loop power adjustment step is used to indicate an offset value for adjusting the transmission power each time. The number of adjustment steps is used to indicate a number of times for adjusting the transmission power. In the case that the number of adjustment steps is a positive integer, the number of adjustment steps is used to indicate increasing the transmission power; in the case that the number of adjustment steps is a negative integer, the number of adjustment steps is used to indicate decreasing the transmission power. The power adjustment indication is used to indicate increasing the transmission power or decreasing the transmission power, and the increasing or decreasing amplitude is the power adjustment step or an agreed step.
[0085] In some embodiments, the first sensing node is a transmitting node that transmits the sensing signal. Optionally, the first sensing node is any one of a base station, a terminal device, a server, a core network element, and a sensing information collector.
[0086] In some embodiments, the first information is carried in other information received by the first sensing node. That is, the first sensing node needs to receive the other information first, and then obtain the first information from the other information.
[0087] In some embodiments, the first information is carried in configuration information. The configuration information is transmitted by the second sensing node to the first sensing node.

[0089] In some embodiments, the first information is carried in sensing feedback information. The sensing feedback information is transmitted by the second sensing node to the first sensing node. Exemplarily, the sensing feedback information is transmitted by the second sensing node to the first sensing node after receiving the sensing signal, and is used to feed back information related to the sensing result. The sensing feedback information is information used to feed back the sensing signal measurement result.
[0090] In some embodiments, the sensing feedback information is feedback on a preceding sensing signal, and the first information is used to determine the transmission power of a subsequent sensing signal.
[0091] In some embodiments, the second sensing node is a receiving node that receives the sensing signal. Optionally, the second sensing node is any one of a base station, a terminal device, a server, a core network element, and a sensing information collector.
[0092] In some embodiments, the first information is agreed by a communication protocol, or agreed by a pre-defined rule. That is, the first sensing node can directly obtain the first information without obtaining the first information by receiving other information.
[0093] In summary, the method provided by the embodiments provides a method for determining the transmission power of a sensing signal. The transmission power of the sensing signal is determined by using information related to a sensing process, so that the first sensing node can determine the accurate transmission power of the sensing signal based on the method, and then transmit the sensing signal based on the determined transmission power. Since the transmission power of the sensing signal is determined based on the information related to the sensing process, the transmission power of the sensing signal determined based on the method can help to ensure the success rate of receiving the sensing signal and the accuracy of the sensing result.

[0132] Step 421: determining at least one power parameter based on the first information;
[0133] The first information and the power parameter have a corresponding relationship. The corresponding relationship is agreed by the communication protocol, or configured by signaling, or implemented by an algorithm.

[0147] In some embodiments, where the first information comprises a sensing measurement quantity, there is a correspondence between the sensing measurement quantity and the power parameter. The correspondence is agreed by the communication protocol, or configured by signaling, or implemented by an algorithm. Exemplarily, the correspondence between the sensing measurement quantity and the power parameter is shown in Table 3 as follows:
[0148] Table 3
[0149] In some embodiments, the sensing measurement quantity and the power parameter are in one-to-one correspondence. That is, one sensing measurement quantity corresponds to one power parameter. For example, sensing measurement quantity 1 corresponds to power parameter 1.
[0150] In some embodiments, the sensing measurement quantity and the power parameter are in one-to-many correspondence.

[0153] In some embodiments, where the first information comprises a beam direction in a sensing process, there is a correspondence between the beam direction and the power parameter. The correspondence is agreed by the communication protocol, or configured by signaling, or implemented by an algorithm. Exemplarily, the correspondence between the beam direction and the power parameter is shown in Table 4 as follows:

[0159] In some embodiments, the power parameter comprises at least one of: an open loop power parameter; a closed loop power parameter; a target power parameter.
[0160] In some embodiments, the open loop power parameter is a power parameter applicable to an open loop power control, the closed loop power parameter is a power parameter applicable to a closed loop power control, and the target power parameter is a power parameter applicable to a preset power control rule other than the open loop power control and the closed loop power control. The preset power control rule can be referred to as a convention rule.
[0161] In some embodiments, the open loop power parameter comprises at least one of a target received power, a path loss adjustment coefficient, a path loss, and a maximum transmit power. The target received power refers to a power at which a receiving node of the sensing signal expects to receive the sensing signal. The path loss refers to a loss of power of the sensing signal in a transmission process. The maximum transmit power is used to limit a maximum value of the transmit power of the sensing signal.
[0162] In some embodiments, the open loop power parameter is used to instruct the first sensing node to determine the transmit power of the sensing signal based on an open loop power control mechanism. For example, assuming that the target received power is -50dbm, the path loss adjustment coefficient is 0.8, and the path loss is 110db, the transmit power of the sensing signal can be determined as -50dbm+0.8*110db.
[0163] In some embodiments, the closed loop power parameter comprises at least one of a closed loop power adjustment step, a number of adjustment steps, and a power adjustment instruction. The closed loop power adjustment step is used to indicate an offset value for adjusting the transmit power each time. For example, assuming that the closed loop power adjustment step is 2db, the transmit power is increased by 2db each time or decreased by 2db each time. The number of adjustment steps is used to indicate a number of times of adjusting the transmit power. For example, assuming that the number of adjustment steps is 2, the transmit power is increased by 2 times or decreased by 2 times. In the case that the number of adjustment steps is a positive integer, the number of adjustment steps is used to indicate an increase in the transmit power; in the case that the number of adjustment steps is a negative integer, the number of adjustment steps is used to indicate a decrease in the transmit power. The power adjustment instruction is used to indicate an increase in the transmit power or a decrease in the transmit power, and the increase or decrease amplitude is the power adjustment step or a convention step.
[0164] In some embodiments, the closed loop power parameter is used to instruct the first sensing node to determine the transmit power of the sensing signal based on a closed loop power control mechanism.
[0165] In some embodiments, the target power parameter comprises at least one of a minimum transmit power, a maximum transmit power, a power change step, a change time interval, a power boost indication, a power reduction indication. The minimum transmit power refers to a minimum value of the transmit power of the sensing signal. The maximum transmit power refers to a maximum value of the transmit power of the sensing signal. The power change step refers to an offset value of each change of the transmit power of the sensing signal. The change time interval refers to a time interval between the n th change and the n+1 th change. The power boost indication refers to an indication of boosting the transmit power. The power reduction indication refers to an indication of reducing the transmit power.
[0166] By querying the at least one power parameter corresponding to the first information according to the correspondence, it is beneficial to make the transmit power of the sensing signal determined subsequently correspond to the first information. Making the first sensing node able to determine the transmit power of the sensing signal based on the first information is beneficial to further guarantee the success rate of the sensing signal being received, thereby guaranteeing the accuracy of the sensing result.
[0167] Step 422: determining the transmit power of the sensing signal based on the at least one power parameter.
[0168] In some embodiments, the transmit power of the sensing signal is determined based on an open-loop power control mechanism. Based on the at least one power parameter, the transmit power of the sensing signal is determined by using the open-loop power control mechanism.
[0169] In some embodiments, the transmit power of the sensing signal is determined based on the at least one open-loop power parameter determined based on the first information.
[0170] In some embodiments, in the case that the number of the open-loop power parameters determined based on the first information is less than the number of all the open-loop power parameters, the transmit power of the sensing signal is determined based on the at least one open-loop power parameter determined based on the first information and other open-loop power parameters. The other open-loop power parameters are agreed by the communication protocol, configured by signaling, or implemented by an algorithm.
[0171] For example, assuming that all the open-loop power parameters comprise a target receive power, a power adjustment coefficient, and a path loss. The first information determines at least one open-loop power parameter comprising the target receive power. Then the power adjustment coefficient and the path loss can be agreed by the communication protocol, configured by signaling, or implemented by an algorithm.
[0172] In some embodiments, the transmit power of the sensing signal is determined based on a closed-loop power control mechanism. Based on the at least one power parameter, the transmit power of the sensing signal is determined by using the closed-loop power control mechanism.
[0173] In some embodiments, the transmit power of the sensing signal is determined based on the at least one closed-loop power parameter determined based on the first information.
[0174] In some embodiments, in case the number of closed loop power parameters determined by the first information is less than the total number of closed loop power parameters, the transmission power of the sensing signal is determined based on the at least one closed loop power parameter determined by the first information and other closed loop power parameters. The other closed loop power parameters are agreed by the communication protocol, or configured by signaling, or implemented by an algorithm.
[0175] For example, assuming that the total closed loop power parameters include a power adjustment step, a number of adjustment steps, and a power adjustment indication. The first information determines at least one closed loop power parameter including the power adjustment step. The number of adjustment steps and the power adjustment indication can be agreed by the communication protocol, or configured by signaling, or implemented by an algorithm.
[0176] In some embodiments, the transmission power of the sensing signal is determined based on an agreed rule. The transmission power of the sensing signal is determined based on the at least one power parameter using the agreed rule.
[0177] In some embodiments, the transmission power of the sensing signal is determined based on an agreed rule. The transmission power of the sensing signal is determined based on the at least one power parameter using the agreed rule.
[0178] In some embodiments, in case the number of target power parameters determined by the first information is less than the total number of target power parameters, the transmission power of the sensing signal is determined based on the at least one target power parameter determined by the first information and other target power parameters. The other target power parameters are agreed by the communication protocol, or configured by signaling, or implemented by an algorithm.
[0179] For example, assuming that the total target power parameters include a minimum transmission power, a maximum transmission power, a power change step, a change time interval, a power increase indication, and a power decrease indication. The first information determines at least one target power parameter including the minimum transmission power, the maximum transmission power, and the power change step. The change time interval, the power increase indication, and the power decrease indication can be agreed by the communication protocol, or configured by signaling, or implemented by an algorithm.
[0180] In some embodiments, the transmission power of the sensing signal is determined based on at least one target power parameter using an agreed rule 1. For example, the agreed rule 1 includes: starting from the minimum transmission power, every interval of the change time interval, then adjusting the transmission power of the sensing signal according to the power change step until the transmission power of the sensing signal reaches the maximum transmission power, and then adjusting the transmission power of the sensing signal from the maximum transmission power to the minimum transmission power in reverse, or starting from the minimum transmission power again to adjust to the maximum transmission power. The sensing signal transmitted within the change time interval uses the same transmission power.
[0181] In some embodiments, the transmission power of the sensing signal is determined based on the at least one target power parameter according to a predetermined rule 2. For example, the predetermined rule 2 includes: starting from the lowest transmission power, adjusting the transmission power of the sensing signal according to a power variation step each time the sensing signal is transmitted until the transmission power of the sensing signal reaches the highest transmission power, then adjusting the transmission power of the sensing signal from the highest transmission power to the lowest transmission power in reverse, or adjusting the transmission power of the sensing signal from the lowest transmission power to the highest transmission power again. Different transmission power is used each time the sensing signal is transmitted.
[0182] In summary, the method provided by the embodiments can adapt the transmission power of the sensing signal to the first information, so as to better adapt to the requirements of the sensing service and further ensure the success rate of receiving the sensing signal and the accuracy of the sensing result.

[0199] FIG. 11 shows a flowchart of a method for determining sending power according to an example embodiment of the present application, the method being performed by a second sensing node, and the method comprising:
[0200] Step 920: sending an effective range of the first information, the effective range being used to indicate at least one of a time domain resource range and a frequency domain resource range of the sensing signal whose transmission power is determined by the first information.
[0201] In some embodiments, the effective range of the first information is carried in other information received by the first sensing node. That is, the first sensing node needs to receive the other information first, and then obtain the effective range of the first information from the other information.
[0202] In some embodiments, the effective range of the first information is carried in configuration information. The configuration information is sent by the second sensing node to the first sensing node. The configuration information is configuration information about the transmission power of the sensing signal.
[0203] In some embodiments, the effective range of the first information is carried in sensing feedback information.

[0294] In some embodiments, the open-loop power parameter is used to instruct the first sensing node to determine the transmit power of the sensing signal based on an open-loop power control mechanism. For example, assuming that the target received power is -50dbm, the path loss adjustment factor is 0.8, and the path loss is 110db, the transmit power of the sensing signal can be determined as -50dbm±0.8*110db.

For example, assuming that the closed-loop power adjustment step is 2db, the transmit power is increased by 2db each time, or the transmit power is decreased by 2db each time. The number of adjustment steps is used to indicate the number of adjustments of the transmit power. For example, assuming that the number of adjustment steps is 2, it indicates that the transmit power is increased 2 times, or it indicates that the transmit power is decreased 2 times. In the case that the number of adjustment steps is a positive integer, the number of adjustment steps is used to indicate the increase of the transmit power; in the case that the number of adjustment steps is a negative integer, the number of adjustment steps is used to indicate the decrease of the transmit power.

The power change step refers to the offset value of each change of the transmit power of the sensing signal. The change time interval refers to the time interval between the n th change and the n+1 th change. The power increase instruction refers to the instruction of increasing the transmit power. The power decrease instruction refers to the instruction of decreasing the transmit power.
[0298] The determining module 1210 is further configured to determine the transmit power of the sensing signal based on the at least one power parameter.
[0299] In some embodiments, the transmission power of the sensing signal is determined based on an open-loop power control mechanism. The transmission power of the sensing signal is determined based on the at least one power parameter using the open-loop power control mechanism.
[0300] In some embodiments, the transmission power of the sensing signal is determined based on at least one open-loop power parameter determined based on the first information.
[0301] In some embodiments, the transmission power of the sensing signal is determined based on at least one open-loop power parameter determined based on the first information and other open-loop power parameters in case the number of open-loop power parameters determined based on the first information is less than the total number of open-loop power parameters. The other open-loop power parameters are either agreed by the communication protocol, or configured by signaling, or implemented by an algorithm.
[0302] For example, assume that the total open-loop power parameters include target received power, power adjustment coefficient, path loss. The first information determines at least one open-loop power parameter including target received power. Then the power adjustment coefficient, path loss can be either agreed by the communication protocol, or configured by signaling, or implemented by an algorithm.
[0303] In some embodiments, the transmission power of the sensing signal is determined based on a closed-loop power control mechanism. The transmission power of the sensing signal is determined based on the at least one power parameter using the closed-loop power control mechanism.
[0304] In some embodiments, the transmission power of the sensing signal is determined based on at least one closed-loop power parameter determined based on the first information.
[0305] In some embodiments, the transmission power of the sensing signal is determined based on at least one closed-loop power parameter determined based on the first information and other closed-loop power parameters in case the number of closed-loop power parameters determined based on the first information is less than the total number of closed-loop power parameters. The other closed-loop power parameters are either agreed by the communication protocol, or configured by signaling, or implemented by an algorithm.
[0306] For example, assume that the total closed-loop power parameters include power adjustment step, number of adjustment steps, power adjustment indication. The first information determines at least one closed-loop power parameter including power adjustment step. Then the number of adjustment steps, power adjustment indication can be either agreed by the communication protocol, or configured by signaling, or implemented by an algorithm.
[0307] In some embodiments, the transmission power of the sensing signal is determined based on an agreed rule. The transmission power of the sensing signal is determined based on the at least one power parameter using the agreed rule.
[0308] In some embodiments, the transmission power of the sensing signal is determined based on at least one target power parameter using the agreed rule.
[0309] In some embodiments, in case the number of target power parameters determined by the first information is less than the total number of target power parameters, the transmission power of the sensing signal is determined based on the at least one target power parameter determined by the first information and other target power parameters. The other target power parameters are agreed by the communication protocol, or configured by signaling, or implemented by an algorithm.
[0310] For example, assuming that the total target power parameters include the minimum transmission power, the maximum transmission power, the power change step, the change time interval, the power increase indication, and the power decrease indication. The first information determines at least one target power parameter including the minimum transmission power, the maximum transmission power, and the power change step. The change time interval, the power increase indication, and the power decrease indication can be agreed by the communication protocol, or configured by signaling, or implemented by an algorithm.
[0311] In some embodiments, the transmission power of the sensing signal is determined based on the at least one target power parameter by using the agreed rule 1. For example, the agreed rule 1 includes: starting from the minimum transmission power, every interval of the change time interval, the transmission power of the sensing signal is adjusted according to the power change step until the transmission power of the sensing signal reaches the maximum transmission power, and then reversely adjusted from the maximum transmission power to the minimum transmission power, or re-started from the minimum transmission power to the maximum transmission power. The sensing signal transmitted within the change time interval uses the same transmission power.
[0312] In some embodiments, the transmission power of the sensing signal is determined based on the at least one target power parameter by using the agreed rule 2. For example, the agreed rule 2 includes: starting from the minimum transmission power, every time the sensing signal is transmitted, the transmission power of the sensing signal is adjusted according to the power change step until the transmission power of the sensing signal reaches the maximum transmission power, and then reversely adjusted from the maximum transmission power to the minimum transmission power, or re-started from the minimum transmission power to the maximum transmission power. Different transmission power is used for each time the sensing signal is transmitted.
