Description

Power allocation method and apparatus

[0001] The present application claims priority from the Chinese patent application No. 202410472809.8 filed on April 18, 2024, and entitled "Power allocation method and apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the field of communication, in particular to a power allocation method and apparatus. BACKGROUND

[0003] In the process of the evolution of the 5th generation (5G) mobile communication system to 5G-advanced (5G-A) technology, communication and perception integrated technology is considered as one of the key technologies that can expand the business capabilities of mobile communication networks. The core idea of this technology is to add perception capabilities to the mobile communication network to build the ability to detect and image targets, so that the two capabilities of communication and perception can coexist in harmony, even mutual benefit.

[0004] The technical principle of perception is different from that of communication. In communication, the sending end modulates information on radio waves and sends it to the receiving end, and the receiving end demodulates the signal carried on the radio wave to obtain the information. In perception, the sending end sends radio waves in a specific direction, and when the radio waves irradiate the target surface, they will form reflected waves, and the receiving end receives the reflected waves and processes them to obtain information such as the position, speed, and type of the target.

[0005] At present, when the sending end sends signals for perception, a fixed power allocation method is usually used in the frequency domain, resulting in poor flexibility of power allocation. SUMMARY

[0006] The present application provides a power allocation method and apparatus, which can improve the flexibility of power allocation.

[0007] In a first aspect, a power allocation method is provided. The method can be performed by a RAN node, or by a component of the RAN node, such as a processor, a chip, or a chip system of the RAN node, or by a logic module or software that can implement all or part of the functions of the RAN node. The method comprises determining a power allocation manner corresponding to a first signal, and transmitting indication information indicating the power allocation manner corresponding to the first signal. The power allocation manner is one of at least two power allocation manners. The at least two power allocation manners include at least one of a first power allocation manner, a second power allocation manner, a third power allocation manner, a fourth power allocation manner, a fifth power allocation manner, or a sixth power allocation manner. The power allocation manner is used to determine the power corresponding to a frequency domain resource unit in a bandwidth occupied by the first signal. The first signal is a reference signal, or a signal carried in a data channel or a control channel.

[0008] Based on the scheme, when transmitting a signal, the RAN node can indicate one of the at least two power allocation manners, so that the transceiver can determine the power corresponding to each frequency domain resource unit based on the power allocation manner indicated by the RAN node, and then transmit or receive the signal according to the power corresponding to each frequency domain resource unit. Since multiple power allocation manners are provided, the RAN node can flexibly select a power allocation manner suitable for the current signal transmission, thereby improving the flexibility and rationality of power allocation, and further improving the sensing performance and / or communication performance based on the rational power allocation.

[0009] In a possible design, the method further comprises receiving or transmitting the first signal according to the power allocation manner corresponding to the first signal.

[0010] In a possible design, the method further comprises transmitting second indication information indicating a power allocation granularity corresponding to the first signal. The power allocation granularity corresponding to the first signal is one of at least two power allocation granularities, and the at least two power allocation granularities include at least one of a subcarrier, a subcarrier group, a resource block, or a resource block group. The first signal is a reference signal, or a signal carried in a data channel or a control channel.

[0011] Based on the possible design, when transmitting a signal, the RAN node can indicate one of at least two power allocation granularities, so that the transceiver can determine the power corresponding to each subcarrier in the bandwidth occupied by the signal based on the power allocation granularity indicated by the RAN node, and transmit or receive the signal according to the power corresponding to each subcarrier. Since the present application provides multiple power allocation granularities, the RAN node can flexibly select the power allocation granularity suitable for the current signal transmission, improve the flexibility and rationality of power allocation, and improve the sensing performance and / or communication performance based on reasonable power allocation.

[0012] In a second aspect, a power allocation method is provided. The method can be executed by a terminal, or by a component of the terminal, such as a processor, a chip, or a chip system of the terminal, or by a logic module or software that can implement all or part of the functions of the terminal. The method includes receiving indication information indicating a power allocation manner corresponding to a first signal, and transmitting or receiving the first signal according to the indication information. The power allocation manner is one of at least two power allocation manners. The at least two power allocation manners include at least one of a first power allocation manner, a second power allocation manner, a third power allocation manner, a fourth power allocation manner, a fifth power allocation manner, or a sixth power allocation manner. The power allocation manner is used to determine the power corresponding to a frequency domain resource unit in the bandwidth occupied by the first signal. The first signal is a reference signal, or a signal carried in a data channel or a control channel. The technical effects brought by the second aspect can refer to the technical effects brought by the first aspect, which will not be repeated here.

[0013] In a possible design, transmitting or receiving the first signal according to the indication information includes determining the power allocation manner corresponding to the first signal according to the indication information, and transmitting or receiving the first signal according to the power allocation manner corresponding to the first signal.

[0014] In a possible design, the method further includes receiving second indication information indicating a power allocation granularity corresponding to the first signal. The power allocation granularity corresponding to the first signal is one of at least two power allocation granularities, and the at least two power allocation granularities include at least one of the following: a subcarrier, a subcarrier group, a resource block, or a resource block group. The first signal is a reference signal, or a signal carried in a data channel or a control channel.

[0015] In a possible design of the first aspect or the second aspect, the first power allocation manner includes: from an edge frequency domain resource unit of the first bandwidth to a center frequency domain resource unit of the first bandwidth, the power corresponding to the frequency domain resource units decreases in turn, and the power corresponding to the frequency domain resource units to which the power is allocated is the same; or the second power allocation manner includes: from the edge frequency domain resource unit to the center frequency domain resource unit, the power corresponding to the frequency domain resource units increases in turn, and the power corresponding to the first frequency domain resource unit is the first power; or the third power allocation manner includes: from the edge frequency domain resource unit to the center frequency domain resource unit, the power corresponding to the frequency domain resource units increases in turn, and the power corresponding to the first frequency domain resource unit is the second power; or the fourth power allocation manner includes: from the edge frequency domain resource unit to the center frequency domain resource unit, the power corresponding to the frequency domain resource units decreases in turn, and the power corresponding to the second frequency domain resource unit is the third power; or the fifth power allocation manner includes: from the edge frequency domain resource unit to the center frequency domain resource unit, the power corresponding to the frequency domain resource units decreases in turn, and the power corresponding to the second frequency domain resource unit is the fourth power; or the sixth power allocation manner includes: the power corresponding to the frequency domain resource unit is related to the channel quality corresponding to the frequency domain resource unit. The first frequency domain resource unit and the second frequency domain resource unit are frequency domain resource units in the first bandwidth, the first power and the second power are different, and the third power and the fourth power are different.

[0016] In a possible design of the first aspect or the second aspect, the first power allocation manner further includes: there is a frequency domain resource unit in the first bandwidth to which the power is not allocated.

[0017] Based on the possible design, multiple power allocation manners can be provided, and thus the RAN node can flexibly select a power allocation manner suitable for current signal transmission according to characteristics of different power allocation manners, thereby improving flexibility and rationality of power allocation. For example, based on the first power allocation manner, power is preferentially allocated to the edge frequency domain resource unit, which can maximize sensing accuracy and sensing resolution. Based on the second power allocation manner, sensing false alarm rate can be reduced. Based on the third power allocation manner, a better compromise between sensing accuracy / sensing resolution and false alarm rate can be achieved, that is, while ensuring sensing accuracy / sensing resolution, a lower false alarm rate can be maintained. Based on the fourth power allocation manner, a better compromise between sensing accuracy / sensing resolution and spectrum efficiency can be achieved, that is, while ensuring sensing accuracy / sensing resolution, spectrum efficiency can be ensured. Based on the fifth power allocation manner, a better compromise between sensing accuracy / sensing resolution, false alarm rate, and spectrum efficiency can be achieved, that is, while ensuring sensing accuracy / sensing resolution, a lower false alarm rate and higher spectrum efficiency can be ensured. Based on the sixth power allocation manner, a higher power can be allocated to a frequency domain resource unit with better channel quality, thereby improving spectrum efficiency.

[0018] With reference to the first aspect or the second aspect, in a possible design, when the first signal is a reference signal for sensing, the at least two power allocation manners include at least one of a first power allocation manner, a second power allocation manner, or a third power allocation manner.

[0019] Based on the possible design, when the first power allocation manner is a high-accuracy / high-resolution power allocation manner, the second power allocation manner is a low-false-alarm-rate power allocation manner, and the third power allocation manner is a power allocation manner that balances sensing accuracy / resolution and false-alarm rate, the three power allocation manners can all guarantee good sensing performance. Therefore, when the first signal is a reference signal for sensing, using one of the three power allocation manners for power allocation can guarantee sensing performance.

[0020] With reference to the first aspect or the second aspect, in a possible design, when the first signal is carried in a data channel or a control channel, the at least two power allocation manners include at least one of a fourth power allocation manner, a fifth power allocation manner, or a sixth power allocation manner.

[0021] Based on the possible design, when the fourth power allocation manner is a power allocation manner that balances sensing accuracy / resolution and spectral efficiency, the fifth power allocation manner is a power allocation manner that balances sensing accuracy / resolution, false-alarm rate, and spectral efficiency, and the sixth power allocation manner is a high-spectral-efficiency power allocation manner, the fourth power allocation manner and the fifth power allocation manner can guarantee good sensing performance and communication performance, and the sixth power allocation manner can guarantee good communication performance. Therefore, when the first signal is carried in a data channel or a control channel, the first signal can be used for sensing and communication, or can be used for communication, and thus using one of the three power allocation manners for power allocation can guarantee sensing performance and communication performance, or can guarantee communication performance.

[0022] With reference to the first aspect or the second aspect, in a possible design, the power allocation manner corresponds to at least one power allocation coefficient set, and the power allocation coefficient set includes a plurality of power allocation coefficients, where the power allocation coefficients are used to determine power corresponding to a frequency domain resource unit in the first bandwidth.

[0023] With reference to the first aspect or the second aspect, in a possible design, the indication information indicates the power allocation manner corresponding to the first signal, including: the indication information indicates an index of the power allocation manner corresponding to the first signal; or the indication information indicates a power allocation coefficient set corresponding to the power allocation manner corresponding to the first signal.

[0024] In a possible design of the first aspect or the second aspect, the second indication information indicates the power allocation granularity corresponding to the first signal, including: the second indication information indicates a type of the power allocation granularity corresponding to the first signal; and / or, the second indication information indicates a value of the power allocation granularity corresponding to the first signal.

[0025] In a possible design of the first aspect or the second aspect, the second indication information is carried in a first field. When the first field is set to a first value, the type of the power allocation granularity corresponding to the first signal is subcarrier; or, when the first field is set to a second value, the type of the power allocation granularity corresponding to the first signal is subcarrier group; or, when the first field is set to a third value, the type of the power allocation granularity corresponding to the first signal is resource block; or, when the first field is set to a fourth value, the type of the power allocation granularity corresponding to the first signal is resource block group.

[0026] In a possible design of the first aspect or the second aspect, the second indication information indicates the power allocation granularity corresponding to the first signal, including: the second indication information indicates a number of resource blocks occupied by the first signal, and the number of resource blocks occupied by the first signal is associated with the power allocation granularity corresponding to the first signal.

[0027] Based on this possible design, the power allocation granularity corresponding to the first signal can be determined based on the number of resource blocks occupied by the first signal. Since the RAN node needs to schedule resource blocks to transmit the first signal when the first signal is transmitted, the scheduling information of the first signal can be reused to indicate the power allocation granularity corresponding to the first signal, thereby saving signaling overhead.

[0028] In a possible design of the first aspect or the second aspect, the second indication information indicates the power allocation granularity corresponding to the first signal, including: the second indication information indicates a signal type of the first signal, and the signal type of the first signal is associated with the power allocation granularity corresponding to the first signal. The signal type of the first signal includes at least one of the following: a reference signal, a signal carried in a data channel, or a signal carried in a control channel.

[0029] Based on this possible design, the power allocation granularity corresponding to the first signal can be determined based on the signal type of the first signal. Since the RAN node can indicate the signal type of the first signal when scheduling transmission of the first signal, the scheduling information of the first signal can be reused to indicate the power allocation granularity corresponding to the first signal, thereby saving signaling overhead.

[0030] In a possible design of the first aspect or the second aspect, when the number of resource blocks occupied by the first signal is greater than or equal to a fifth value, the power allocation granularity corresponding to the first signal is 2 resource blocks; when the number of resource blocks occupied by the first signal is less than the fifth value and greater than or equal to a sixth value, the power allocation granularity corresponding to the first signal is 1 resource block; when the number of resource blocks occupied by the first signal is less than the sixth value and greater than or equal to a seventh value, the power allocation granularity corresponding to the first signal is 0.5 resource block; and when the number of resource blocks occupied by the first signal is less than the seventh value, the power allocation granularity corresponding to the first signal is 1 subcarrier.

[0031] In a possible design of the first aspect or the second aspect, when the signal type of the first signal is a signal carried in a data channel or a control channel, the power allocation granularity corresponding to the first signal is 2 resource blocks; when the signal type of the first signal is a reference signal and the reference signal is used for sensing and communication, the power allocation granularity corresponding to the first signal is 1 resource block; and when the signal type of the first signal is a reference signal and the first signal is dedicated for sensing, the power allocation granularity corresponding to the first signal is 0.5 resource block.

[0068] In a wireless communication system, a sending end modulates information on a radio wave and sends it to a receiving end, and the receiving end demodulates the signal carried on the radio wave to obtain the information. Generally, according to the difference between the sending end and the receiving end, the communication can be divided into different types. For example, sending information from a network device to a terminal device is called downlink communication, and sending information from a terminal device to a network device is called uplink communication.

[0069] There can be multiple duplex modes in a wireless communication system. For example, in a long term evolution (LTE), long term evolution advanced (LTE-A) communication system and a new radio (NR) system, the duplex mode can be divided into a frequency division duplex (FDD) mode and a time division duplex (TDD) mode. For a wireless communication system working in a TDD mode, the downlink carrier and the uplink carrier are carriers of the same carrier frequency; for a wireless communication system working in an FDD mode, the downlink carrier and the uplink carrier can be carriers of different carrier frequencies.

[0070] In addition, the multiple access mode adopted by the wireless communication system is usually an orthogonal frequency division multiplexing access (OFDMA) mode. The main feature is to divide the transmission resources into mutually orthogonal resource elements (REs), and the signals sent by the sending end are transmitted to the receiving end on the REs. Since the different REs are mutually orthogonal, the receiving end can receive the signals on each RE separately.

[0071] The technical principle of sensing is different from communication. Sensing refers to detecting the parameters of a target in a physical environment, such as the position of the target, the speed of the target, etc. In sensing, the sending end sends radio waves in a specific direction, and when the radio waves irradiate the surface of the target, reflected waves are formed. The receiving end receives the reflected waves and processes them to obtain information such as the position, speed, and type of the target. Sensing can also be referred to as detection.

[0072] Generally, sensing modes can be divided into self-sending and self-receiving sensing modes and self-sending and other-receiving sensing modes. In the self-sending and self-receiving sensing mode, the sending end and the receiving end of the sensing signal are the same device, i.e., the sensing station both sends the sensing signal and receives the signal reflected by the sensing signal on the surface of the target. In the self-sending and other-receiving sensing mode, the sending end and the receiving end of the sensing signal are different devices, i.e., sensing station A sends the sensing signal, and sensing station B receives the signal reflected by the sensing signal on the surface of the target.

[0073] The integration of sensing and communication is driven by future business needs and technology development trends. With the integration of sensing and communication, future base stations and terminals will have both communication and sensing capabilities. For example, future base stations will have the ability to monitor the status of targets (such as low-altitude flying objects, traffic flow, and hot human flow) in the coverage area, detect, locate, and identify targets. In addition, they can also have the ability to measure the real-time state of the natural environment, weather, etc. in the coverage area.

[0074] Future terminals will be upgraded to intelligent agents, and the capabilities of unmanned vehicles, drones, robots, and other intelligent devices will continue to improve. Intelligent agents may need to identify the pose, motion, and expression of people, enhance human-computer interaction, and identify the motion state between multiple intelligent agents to improve intelligent collaboration. Further, intelligent agents may need to identify the attributes inside the human body, inside products, and inside articles to provide remote, AI-based unmanned physical examination, quality inspection, and security inspection services. These services further drive the integration of intelligent agent sensing and communication, not only improving the information interaction capabilities between intelligent agents and between intelligent agents and systems, but also reducing the size, power consumption, and cost of intelligent agent hardware devices, thereby promoting the popularization of new services.

[0075] The sixth generation (6G) wireless network faces the future, and the communication ability and the sensing ability will be symbiotic, evolving into the "integrated sensing and communication" technology direction, giving the 6G network the ability to sense the physical world at all times and everywhere, fully satisfying the intercommunication of multi-dimensional senses, and effectively supporting the wide-area expansion of communication ability, opening up the application space beyond traditional mobile communication networks.

[0076] For example, integrated sensing and communication (ISAC) is a typical architecture of the integration of sensing and communication. ISAC provides high-quality communication and high-precision sensing functions by sharing software and hardware resources in the same system, reduces costs, and improves system performance. Among them, the communication function can be understood as traditional data transmission, etc., and the sensing function includes ranging, speed measurement, angle measurement, imaging, detection, etc.

[0077] Currently, when the sending end transmits a signal for sensing, a fixed power allocation method is usually used in the frequency domain. For example, as shown in FIG. 1, taking the horizontal axis as power and the vertical axis as frequency domain resource units as an example, when transmitting a signal for sensing on frequency domain resource unit #1 to frequency domain resource unit #6, each frequency domain resource unit is allocated equal power.

[0078] However, a single fixed power allocation method will usually result in impaired sensing performance under different circumstances. Based on this, the present application provides a power allocation method. In this method, when transmitting a signal, the network can indicate one of at least two power allocation methods, so that the sending and receiving ends can transmit and receive signals based on the power allocation method indicated by the network. Since multiple power allocation methods are provided, the network can flexibly select the appropriate power allocation method for current signal transmission, improving the flexibility and rationality of power allocation, and thus improving the sensing performance based on reasonable power allocation.

[0079] The technical scheme of the embodiment of the present application can be used in various communication systems, which can be a third generation partnership project (3GPP) communication system, for example, a long term evolution (LTE) system, a fourth generation (4G) system such as a new radio (NR) system, a 5G system, a system of mixed networking of LTE and 5G, a non-terrestrial network (NTN), or other next-generation communication systems such as a 6G communication system. The communication system can also be a non-3GPP communication system, which is not limited.

[0080] The technical solutions of the embodiments of the present application can be applied to various scenarios, such as a scenario of terminal-to-network communication, or a scenario of terminal-to-terminal direct communication such as device-to-device (D2D), machine-to-machine (M2M), vehicle-to-everything (V2X) communication, or a scenario of perception or integrated communication and perception.

[0081] In some possible implementations, in various scenarios where the present application is applicable, a perception transmitter transmits a signal for perception, the signal generates a return signal through target reflection, a perception receiver receives the return signal, and then perceives the position, speed, and other information of the target. The target can include but is not limited to mobile targets such as vehicles, low-altitude drones, and pedestrians, and can also include stationary objects in the environment such as buildings and the ground.

[0082] For example, after the perception receiver receives the return signal, a receive sequence is obtained based on the return signal, a correlation operation is performed on the receive sequence and a local sequence, and the position, speed, and other information of the target are perceived according to the result of the correlation operation. The local sequence is a sequence used to generate the transmitted signal. The local sequence can be indicated by the perception transmitter to the perception receiver.

[0083] The correlation operation can be understood as a processing process between two sequences, including multiplication and addition operations between different elements of the two sequences. The correlation operation includes autocorrelation and cross-correlation. In addition, in the case of considering Doppler frequency offset, the autocorrelation of the sequence can also be called self-fuzziness, and the cross-correlation between the sequences can also be called cross-fuzziness. The correlation operation result of the sequence can be understood as a fuzziness function, and perception can be performed based on the correlation information of the main lobe and the side lobe of the fuzziness function.

[0084] As a possible implementation, the signal can be used only for perception, for example, the signal can be a reference signal dedicated to perception. At this time, the signal can also be called a perception signal, a detection signal, a linear frequency modulation signal, a radar signal, a radar perception signal, a radar detection signal, or an environmental perception signal, etc.

[0085] The sensing signal can be an orthogonal frequency division multiplexing (OFDM) signal modulated with a specific sequence on subcarriers. The specific sequence can be any one of a Zadoff-Chu sequence (ZC sequence), a pseudo-random sequence, a predefined sequence, and the like. The pseudo-random sequence can include any one of a maximum length linear feedback shift register sequence (m-sequence), a Gold sequence, and the like. The predefined sequence can be a random data symbol, for example, a random data symbol modulated by quadrature phase shift keying (QPSK), 16 quadrature amplitude modulation (QAM), or the like.

[0086] As another possible implementation, the signal can be used for sensing and communication, i.e., the signal is used for both communication and sensing. In this case, the signal can also be referred to as a communication-sensing fusion signal. The signal used for communication can be understood as carrying communication data or a communication reference signal sequence that needs to be transmitted between communication devices. For example, the signal can be a reference signal in communication (also referred to as a communication reference signal or a communication reference signal sequence), or a signal carried in a data channel or a control channel (also referred to as communication data).

[0087] The data channel can include, but is not limited to, a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), and the like. The control channel can include, but is not limited to, a physical downlink control channel (PDCCH), a physical uplink control channel (PUCCH), and the like.

[0088] The sensing scene or the communication-sensing integrated scene can be divided into six scenes as shown in FIGS. 2 to 4 according to the sensing mode. FIGS. 2 to 4 take a vehicle as an example, and the target can also be other objects, which are not limited.

[0089] Referring to FIG. 2, in scenario 1, the sending end and the receiving end of the signal are the same radio access network (RAN) node; in scenario 2, the sending end and the receiving end of the signal are the same terminal. Exemplarily, in scenario 1 and scenario 2, the signal can be a sensing signal.

[0090] Referring to FIG. 3, in scenario 3, the sending end of the signal is a RAN node A, and the receiving end is another RAN node B. It is worth noting that the target in the environment and the RAN node B can be the same device or different devices. For example, when the target in the environment and the RAN node B are the same device, the signal sent by the RAN node A can be a sense-fusion signal, that is, the RAN node A sends the sense-fusion signal for sensing, and the sense-fusion signal also carries the communication data or the communication reference sequence that the RAN node A needs to transmit to the RAN node B. When the target in the environment and the RAN node B are not the same device, the signal sent by the RAN node A can be a sensing signal.

[0091] In scenario 4, the sending end of the signal is a terminal A, and the receiving end is another terminal B. It is worth noting that the target in the environment and the terminal B can be the same device or different devices. For example, when the target in the environment and the terminal B are the same device, the signal sent by the terminal A can be a sense-fusion signal, that is, the terminal A sends the sense-fusion signal for sensing, and the sense-fusion signal also carries the communication data or the communication reference sequence that the terminal A needs to transmit to the terminal B. When the target in the environment and the terminal B are not the same device, the signal sent by the terminal A can be a sensing signal. In addition, the terminal A can also simultaneously send a communication signal to the terminal B in a frequency division multiplexing or space division multiplexing manner. The communication signal can refer to a signal transmitted between communication devices for communication.

[0092] Referring to FIG. 4, in scenario 5, the sending end of the signal is a RAN node, and the receiving end is a terminal. It is worth noting that the target in the environment and the terminal can be the same device or different devices. For example, when the target in the environment and the terminal are the same device, the signal sent by the RAN node can be a sense-fusion signal, that is, the RAN node sends the sense-fusion signal for sensing, and the sense-fusion signal also carries the communication data or the communication reference sequence that the RAN node needs to transmit to the terminal. When the target in the environment and the terminal are not the same device, the signal sent by the RAN node can be a sensing signal. In addition, the RAN node can also simultaneously send a communication signal to the terminal in a frequency division multiplexing or space division multiplexing manner.

[0093] In scenario 6, the terminal is the sending end of the signal, and the RAN node is the receiving end. It is worth noting that the target in the environment and the RAN node can be the same device or different devices. For example, when the target in the environment and the RAN node are the same device, the signal sent by the terminal can be a sense-fusion signal, that is, the terminal sends a sense-fusion signal for sensing, and the sense-fusion signal also carries communication data or a communication reference sequence that the terminal needs to transmit to the RAN node. When the target in the environment and the RAN node are not the same device, the signal sent by the terminal can be a sensing signal. In addition, the terminal can also send a communication signal at the same time by using frequency division multiplexing or space division multiplexing, and communicate with the RAN node.

[0094] In a possible implementation, the RAN node can be deployed in a RAN. The RAN can be a 3GPP related cellular system, such as a 4G, 5G mobile communication system, or a future-oriented evolved system (such as a 6G mobile communication system). The RAN can also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (CRAN), or a WiFi system. The RAN can also be a communication system that combines two or more of the above systems.

[0095] The RAN node, which can also be referred to as an access network device, a RAN entity, or an access node, etc., constitutes part of the communication system and helps the terminal to realize wireless access.

[0096] In a possible scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. The RAN node can be a macro base station, a micro base station or an indoor station, a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in the V2X technology can be a road side unit (RSU). All or part of the functions of the RAN node in this application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform). The RAN node in this application can also be a logical node, a logical module or software that can realize all or part of the functions of the RAN node.

[0097] In another possible scenario, a terminal is assisted by multiple RAN nodes to implement wireless access, and different RAN nodes respectively implement part of functions of a base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0098] In different systems, the CU (or CU-CP and CU-UP), DU, or RU can also have different names, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the convenience of description, the CU, CU-CP, CU-UP, DU, and RU are taken as examples for description in this application. Any one of the CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0099] A terminal can also be referred to as a terminal device, a UE mobile station, a mobile terminal, etc. The terminal can be widely applied to various scenarios, such as device-to-device (D2D) communication, V2X communication, machine-type communication (MTC), internet of things (IOT), virtual reality, augmented reality, industrial control, automatic driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. Embodiments of this application do not limit the device form of the terminal.

[0101] It should be noted that in the following embodiments of the present application, the message names between each execution subject, the names of each parameter, or the names of each information, etc. are only an example, and in other embodiments, they can also be other names, and the method provided by the present application does not make specific limitations on this.

[0102] It can be understood that in the embodiments of the present application, the execution subject can be a terminal or a RAN node, and the terminal or the RAN node can perform part or all of the steps in the embodiments of the present application. These steps or operations are only examples, and the embodiments of the present application can also perform other operations or variations of various operations. In addition, each step can be executed in a different order according to the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application are executed.

[0103] It can be understood that the RAN node or the terminal is taken as an example of the execution subject in the present application, but the present application does not limit the interactive execution subject. For example, the method executed by the RAN node in the present application can also be executed by a module (such as a chip, a chip system, or a processor) applied to the RAN node, and can also be implemented by a logical node, a logical module or software capable of implementing all or part of the RAN node function; the method executed by the terminal in the present application can also be executed by a module (such as a chip, a chip system, or a processor) applied to the terminal, and can also be implemented by a logical node, a logical module or software capable of implementing all or part of the terminal function.

[0104] In addition, "sending information" in the present application can be understood as one device sending information to another device, or can also be understood as one logical module in a device sending information to another logical module. For example, "the RAN node sending information" can be understood as the RAN node sending information to another device (such as a terminal), or can be understood as a logical module 1 (such as a processing module) in the RAN node sending information to a logical module 2 (such as a transceiver module) in the RAN node.

[0105] In the present application, "receiving information" can be understood as a device receiving information from another device, or can also be understood as a logical module in a device receiving information from another logical module. For example, "terminal receiving information" can be understood as the terminal receiving information from another device (such as a RAN node), or can be understood as a logical module 1 (such as a processing module) in the terminal receiving information from a logical module 2 (such as a transceiver module) in the terminal.

[0106] In the present application, "sending information to (for example, a terminal)" or related illustrations in the drawings can be understood as that the destination of the information is the terminal. It can include directly or indirectly sending information to the terminal. "Receiving information from (for example, a RAN node)" or "receiving information from (for example, a RAN node)" or "receiving information sent by (for example, a RAN node)", or related illustrations in the drawings can be understood as that the source of the information is the RAN node, and can include directly or indirectly receiving information from the RAN node. The information between the source and the destination of the information sending can be processed as necessary, for example, format change, etc., but the destination can understand the valid information from the source. Similar expressions in the present application can be similarly understood, and will not be repeated here.

[0107] In order to facilitate the understanding of the scheme of the present application, before introducing the power allocation method provided by the present application, the sensing performance, communication performance and six power allocation modes provided by the present application are first described below.

[0108] In a possible implementation, the sensing performance mainly includes one or more of sensing accuracy, sensing resolution and false alarm rate. The communication performance mainly includes spectrum efficiency and coverage performance.

[0109] The sensing accuracy is mainly used to represent the deviation between the sensing result of the target and the ideal true result. Taking distance sensing as an example, if the distance between the sensed target and the sensing device is obtained as 6 meters (meter, m) through sensing, and the true situation is that the distance between the sensed target and the sensing device is 5 m, then the sensing error and the sensing accuracy are 1 m. Wherein, the sensing device can be understood as a device performing sensing.

[0110] The sensing resolution is mainly used to represent the minimum ability to distinguish two different targets. Taking distance sensing as an example, a distance resolution of 1 m can be understood as that when the distance between two sensed targets is greater than 1 m, the sensing device can distinguish that there are two targets; when the distance between two sensed targets is less than 1 m, the sensing device cannot distinguish that there are two targets.

[0111] The false alarm rate is mainly used to represent the performance of falsely deciding a false target in the case of no target.

[0112] Spectrum efficiency is mainly used to characterize the utilization efficiency of spectrum by communication. Coverage performance is mainly used to characterize the utilization efficiency of power by communication.

[0113] In a possible implementation, the present application provides a first power allocation manner, a second power allocation manner, a third power allocation manner, a fourth power allocation manner, a fifth power allocation manner and a sixth power allocation manner. In each of the six power allocation manners, the power corresponding to all frequency domain resource units in the bandwidth is not completely the same, that is, at least two different powers exist in the power corresponding to all frequency domain resource units. The six power allocation manners are described below respectively.

[0114] 1. The first power allocation manner:

[0115] The first power allocation manner includes: from the edge frequency domain resource unit of the bandwidth to the center frequency domain resource unit of the bandwidth, the power allocation priority of the frequency domain resource unit decreases in turn.

[0116] As a possible implementation, the bandwidth refers to the bandwidth occupied by the to-be-sent signal or the bandwidth scheduled by the RAN node to carry the to-be-sent signal.

[0117] As a possible implementation, the type of the frequency domain resource unit can be a subcarrier, a subcarrier group, a resource block (RB) or a resource group (RG). The subcarrier group includes at least two subcarriers, and the RG includes at least two RBs.

[0118] As a possible implementation, the edge frequency domain resource unit of the bandwidth is the frequency domain resource unit with the lowest or highest frequency in the bandwidth. The frequency can be the lowest frequency or the highest frequency or the center frequency of the frequency domain resource unit.

[0119] As a possible implementation, the center frequency domain resource unit of the bandwidth is the frequency domain resource unit located in the middle of the bandwidth. In the case where the bandwidth includes an even number of frequency domain resource units, there are two center frequency domain resource units; in the case where the bandwidth includes an odd number of frequency domain resource units, there is one center frequency domain resource unit.

[0120] For example, if the bandwidth includes 6 frequency domain resource units, and the 6 frequency domain resource units are numbered as #1-#6 in the order of frequency from low to high, the edge frequency domain resource units are frequency domain resource unit #1 and frequency domain resource unit #6, and the center frequency domain resource units are frequency domain resource unit #3 and frequency domain resource unit #4. Alternatively, if the bandwidth includes 7 frequency domain resource units, and the 7 frequency domain resource units are numbered as #1-#7 in the order of frequency from low to high, the edge frequency domain resource units are frequency domain resource unit #1 and frequency domain resource unit #7, and the center frequency domain resource units are frequency domain resource unit #4.

[0121] As a possible implementation, in the first power allocation manner, there are frequency domain resource units to which no power is allocated. For example, the frequency domain resource units to which no power is allocated are not edge frequency domain resource units.

[0122] As a possible implementation, in the first power allocation manner, the power corresponding to the frequency domain resource units to which power is allocated is the same; or the power corresponding to the frequency domain resource units to which power is allocated is different, for example, the power corresponding to two frequency domain resource units symmetric about the center frequency domain resource unit to which power is allocated is the same, and the power corresponding to two frequency domain resource units asymmetric about the center frequency domain resource unit to which power is allocated is different.

[0123] Optionally, in the embodiments of the present application, two frequency domain resource units symmetric about the center frequency domain resource unit can be understood as: the difference between the index of the frequency domain resource unit A and the index of the center frequency domain resource unit is the same as the difference between the index of the frequency domain resource unit B and the index of the center frequency domain resource unit; or it can also be understood as: the difference between the frequency of the frequency domain resource unit A and the frequency of the center frequency domain resource unit is the same as the difference between the frequency of the frequency domain resource unit B and the frequency of the center frequency domain resource unit. The frequency of the frequency domain resource unit can be the lowest frequency, the highest frequency or the center frequency of the frequency domain resource unit.

[0124] For example, assuming that the bandwidth includes 6 frequency domain resource units, and the 6 frequency domain resource units are sequentially numbered as #1-#6 in the order of frequency from low to high, and that frequency domain resource unit #1, frequency domain resource unit #2, frequency domain resource unit #5, and frequency domain resource unit #6 are allocated power, and that frequency domain resource unit 3 and frequency domain resource unit 4 are not allocated power, as shown in (a) of FIG. 5, the power corresponding to frequency domain resource unit #1, frequency domain resource unit #2, frequency domain resource unit #5, and frequency domain resource unit #6 can be the same; or, as shown in (b) of FIG. 5, frequency domain resource unit #1 and frequency domain resource unit #6 are symmetric about the center frequency domain resource, and the power corresponding to the two can be the same (denoted as power 1), frequency domain resource unit #2 and frequency domain resource unit #5 are symmetric about the center frequency domain resource, and the power corresponding to the two can be the same (denoted as power 2), and power 1 and power 2 can be different. The dashed line indicates that no power is allocated.

[0125] As a first possible implementation, the power allocation priority of the frequency domain resource units decreases in turn from the edge frequency domain resource unit of the bandwidth to the center frequency domain resource unit of the bandwidth, which can also be understood as: starting from the edge frequency domain resource unit of the bandwidth, the frequency domain resource units are sequentially allocated power in the order of increasing or decreasing frequency, until the power allocation is complete.

[0126] For example, assuming that the bandwidth includes 6 frequency domain resource units, and the 6 frequency domain resource units are sequentially numbered as #1-#6 in the order of frequency from low to high, the power can be allocated first to frequency domain resource unit #1 and frequency domain resource unit #6, then to frequency domain resource unit #2 and frequency domain resource unit #5, and so on, until the power allocation is complete. The power corresponding to frequency domain resource unit #1 and frequency domain resource unit #6 can be the same, and the power corresponding to frequency domain resource unit #2 and frequency domain resource unit #5 can be the same. The power corresponding to frequency domain resource unit #1 and frequency domain resource unit #2 can be the same or different.

[0127] Optionally, each frequency domain resource unit can correspond to a power threshold, which can be understood as an upper limit of the power value. When power is allocated based on the first power allocation mode, the power value allocated to the frequency domain resource unit with the highest priority can be the same as the power threshold corresponding to the frequency domain resource unit. For the frequency domain resource unit with the next highest priority, if the remaining power value is greater than or equal to the power threshold corresponding to the frequency domain resource unit, the power value allocated to the frequency domain resource unit can be the same as the power threshold corresponding to the frequency domain resource unit; if the remaining power value is less than the power threshold corresponding to the frequency domain resource unit, the power value allocated to the frequency resource unit is the remaining power value. The power thresholds corresponding to different resource units can be the same or different, and are not limited.

[0128] For example, if the bandwidth includes 6 frequency domain resource units, and the 6 frequency domain resource units are numbered in the order of low to high frequency as #1-#6, the frequency domain resource unit #1 and the frequency domain resource unit #6 can be first allocated the power equal to the corresponding power threshold. When allocating power to the frequency domain resource unit #2 and the frequency domain resource unit #5, if the remaining power is greater than or equal to the sum of the corresponding power thresholds of the two, the power allocated to the two is the same as the corresponding power threshold; if the remaining power is less than the sum of the corresponding power thresholds of the two, the power allocated to the two is less than the corresponding power threshold. After the power is allocated to the frequency domain resource unit #2 and the frequency domain resource unit #5, if there is still remaining power, the power is allocated to other frequency domain resource units until the power allocation is completed.

[0129] As a second possible implementation, the power allocation priority of the frequency domain resource units decreases in turn from the edge frequency domain resource units of the bandwidth to the center frequency domain resource units of the bandwidth, which can also be understood as: when the power allocated to the frequency domain resource units is the same, the number N of the frequency domain resource units to which the power can be allocated is first determined, and then the N frequency domain resource units include N1 frequency domain resource units starting from the frequency domain resource unit with the lowest frequency on the edge and N2 frequency domain resource units starting from the frequency domain resource unit with the highest frequency on the edge.

[0130] Wherein, N1+N2=N. When N is even, N1=N2=N / 2. When N is odd, Or, Or, Or,

[0131] For example, if the bandwidth includes 6 frequency domain resource units, and the 6 frequency domain resource units are numbered in the order of low to high frequency as #1-#6, the number N of the frequency domain resource units to which the power can be allocated is 4, then the frequency domain resource unit #1, the frequency domain resource unit #6, the frequency domain resource unit #2 and the frequency domain resource unit #5 are allocated to the power, and the power of the four is the same.

[0132] Based on the first power allocation method, the power is preferentially allocated to the edge frequency domain resource units, which can make the main lobe width of the signal ambiguity function the narrowest. Since the main lobe width is usually narrower, the perception accuracy / resolution is higher, so the method can maximize the perception accuracy and perception resolution. Therefore, the first power allocation method can also be called a high-precision / high-resolution power allocation method.

[0133] 2. Second power allocation method:

[0134] The second power allocation manner includes: from the edge frequency domain resource unit of the bandwidth to the center frequency domain resource unit of the bandwidth, the power corresponding to the frequency domain resource unit increases in turn. Wherein, the implementation of the bandwidth, the edge frequency domain resource unit and the center frequency domain resource unit can refer to the related description in the first power allocation manner, and will not be described here.

[0135] As a possible implementation, in the case that there are multiple center frequency domain resource units in the bandwidth, the power corresponding to the multiple center frequency domain resource units is the same.

[0136] As a possible implementation, the power corresponding to the two frequency domain resource units symmetrical about the center frequency domain resource unit is the same. Alternatively, the power corresponding to the two frequency domain resource units symmetrical about the center frequency domain resource unit is different. The implementation of the two frequency domain resource units symmetrical about the center frequency domain resource unit can refer to the related description in the first power allocation manner, and will not be described here.

[0137] For example, as shown in (a) of FIG. 6, the bandwidth includes 6 frequency domain resource units, and the 6 frequency domain resource units are sequentially numbered as #1-#6 in the order of frequency from low to high, the center frequency domain resource units are frequency domain resource unit #3 and frequency domain resource unit #4, the power corresponding to the two is the same, frequency domain resource unit #1 and frequency domain resource unit #6 are symmetrical about the center frequency domain resource, the power corresponding to the two can be the same (denoted as power 1), frequency domain resource unit #2 and frequency domain resource unit #5 are symmetrical about the center frequency domain resource, the power corresponding to the two can be the same (denoted as power 2), and power 1 is less than power 2.

[0138] Alternatively, as shown in (b) of FIG. 6, the center frequency domain resource units are frequency domain resource unit #3 and frequency domain resource unit #4, the power corresponding to the two is the same, the power corresponding to frequency domain resource unit #2 is greater than the power corresponding to frequency domain resource unit #1, and the power corresponding to frequency domain resource unit #5 is greater than the power corresponding to frequency domain resource unit #6. The power corresponding to frequency domain resource unit #1 and frequency domain resource unit #6 is different, and the power corresponding to frequency domain resource unit #2 and frequency domain resource unit #5 is different.

[0139] As a possible implementation, from the edge frequency domain resource unit of the bandwidth to the center frequency domain resource unit of the bandwidth, the power corresponding to the frequency domain resource unit increases in turn, which can also be understood as: for the frequency domain resource unit with a frequency higher than the center frequency domain resource unit, the higher the frequency, the lower the corresponding power, and the lower the frequency, the higher the corresponding power; for the frequency domain resource unit with a frequency lower than the center frequency domain resource unit, the higher the frequency, the higher the corresponding power, and the lower the frequency, the lower the corresponding power.

[0140] Based on the second power allocation manner described above, the frequency domain resource units located in the middle of the bandwidth are allocated higher power, and the frequency domain resource units located at the edge of the bandwidth are allocated lower power, which can make the peak-to-sidelobe ratio of the ambiguity function of the signal as low as possible, thereby reducing the false alarm rate of perception. Therefore, the second power allocation manner can also be referred to as a low false alarm rate power allocation manner.

[0141] 3. A third power allocation manner:

[0142] The third power allocation manner includes that the power corresponding to the frequency domain resource units increases successively from the edge frequency domain resource units of the bandwidth to the center frequency domain resource units of the bandwidth. That is, the third power allocation manner is similar to the second power allocation manner, and the difference between the two is that the power corresponding to the same frequency domain resource unit is different when the second power allocation manner and the third power allocation manner are respectively used for power allocation.

[0143] Taking any frequency domain resource unit (denoted as a first frequency domain resource unit) in the bandwidth as an example, when the second power allocation manner is used for power allocation, the power corresponding to the first frequency domain resource unit is a first power; when the third power allocation manner is used for power allocation, the power corresponding to the first frequency domain resource unit is a second power. The first power and the second power are different. The remaining implementation of the third power allocation manner can refer to the related description of the second power allocation manner, and will not be described here.

[0144] For example, for the first frequency domain resource unit, the first power allocated by the second power allocation manner is greater than a first threshold, and the second power allocated by the third power allocation manner is less than the first threshold.

[0145] As a possible implementation, the difference between the third power allocation manner and the second power allocation manner is that when the second power allocation manner is used for power allocation, the difference between the maximum power and the minimum power among the powers corresponding to all frequency domain resource units included in the bandwidth is less than a second threshold, and when the third power allocation manner is used for power allocation, the difference between the maximum power and the minimum power among the powers corresponding to all frequency domain resource units included in the bandwidth is greater than the second threshold.

[0146] Based on the third power allocation manner described above, the main lobe of the ambiguity function of the signal can be relatively narrow while the peak-to-sidelobe ratio is also relatively low, thereby realizing a better compromise between the perception accuracy / perception resolution and the false alarm rate, that is, the perception accuracy / perception resolution can be guaranteed while maintaining a relatively low false alarm rate. Therefore, the third power allocation manner can also be referred to as a power allocation manner for compromising between the perception accuracy / resolution and the false alarm rate.

[0147] 4. A fourth power allocation manner:

[0148] The fourth power allocation manner includes: from the edge frequency domain resource unit of the bandwidth to the center frequency domain resource unit of the bandwidth, the power corresponding to the frequency domain resource unit decreases in turn. Wherein, the implementation of the bandwidth, the edge frequency domain resource unit and the center frequency domain resource unit can refer to the related description in the first power allocation manner, and will not be described here.

[0149] As a possible implementation, in the case that there are multiple center frequency domain resource units in the bandwidth, the power corresponding to the multiple center frequency domain resource units is the same.

[0150] As a possible implementation, the power corresponding to the two frequency domain resource units symmetrical about the center frequency domain resource unit is the same. Alternatively, the power corresponding to the two frequency domain resource units symmetrical about the center frequency domain resource unit is different. The implementation of the two frequency domain resource units symmetrical about the center frequency domain resource unit can refer to the related description in the first power allocation manner, and will not be described here.

[0151] For example, as shown in (a) of FIG. 7, the bandwidth includes 6 frequency domain resource units, and the 6 frequency domain resource units are sequentially numbered as #1-#6 in the order of frequency from low to high, the center frequency domain resource units are frequency domain resource unit #3 and frequency domain resource unit #4, the power corresponding to the two is the same, frequency domain resource unit #1 and frequency domain resource unit #6 are symmetrical about the center frequency domain resource, the power corresponding to the two can be the same (denoted as power 1), frequency domain resource unit #2 and frequency domain resource unit #5 are symmetrical about the center frequency domain resource, the power corresponding to the two can be the same (denoted as power 2), and power 1 is greater than power 2.

[0152] Alternatively, as shown in (b) of FIG. 7, the center frequency domain resource units are frequency domain resource unit #3 and frequency domain resource unit #4, the power corresponding to the two is the same, the power corresponding to frequency domain resource unit #2 is less than the power corresponding to frequency domain resource unit #1, and the power corresponding to frequency domain resource unit #5 is less than the power corresponding to frequency domain resource unit #6. The power corresponding to frequency domain resource unit #1 and frequency domain resource unit #6 is different, and the power corresponding to frequency domain resource unit #2 and frequency domain resource unit #5 is different.

[0153] As a possible implementation, from the edge frequency domain resource unit of the bandwidth to the center frequency domain resource unit of the bandwidth, the power corresponding to the frequency domain resource unit decreases in turn, which can also be understood as: for the frequency domain resource unit with a frequency higher than the center frequency domain resource unit, the higher the frequency, the higher the corresponding power, and the lower the frequency, the lower the corresponding power; for the frequency domain resource unit with a frequency lower than the center frequency domain resource unit, the higher the frequency, the lower the corresponding power, and the lower the frequency, the higher the corresponding power.

[0154] Based on the fourth power allocation manner described above, the frequency domain resource units located in the middle of the bandwidth are allocated lower power, and the frequency domain resource units located at the edge of the bandwidth are allocated higher power, which can make the main lobe width of the ambiguity function of the signal relatively narrow, and the distortion of the signal is relatively small, thereby realizing a better compromise between the perception accuracy / perception resolution and the spectrum efficiency, that is, while ensuring the perception accuracy / perception resolution, the spectrum efficiency can be ensured. Therefore, the fourth power allocation manner can also be referred to as a power allocation manner for compromising the perception accuracy / resolution and the spectrum efficiency.

[0155] 5. A fifth power allocation manner:

[0156] The fifth power allocation manner includes: from the edge frequency domain resource units of the bandwidth to the center frequency domain resource units of the bandwidth, the power corresponding to the frequency domain resource units decreases in turn. That is, the fifth power allocation manner is similar to the fourth power allocation manner, and the difference between the two is that: for the same frequency domain resource unit, when the fourth power allocation manner and the fifth power allocation manner are used for power allocation respectively, the power corresponding to the frequency domain resource unit is different.

[0157] Taking any frequency domain resource unit (denoted as a second frequency domain resource unit) in the bandwidth as an example, when the fourth power allocation manner is used for power allocation, the power corresponding to the second frequency domain resource unit is a third power; when the fifth power allocation manner is used for power allocation, the power corresponding to the second frequency domain resource unit is a fourth power. The third power and the fourth power are different. The remaining implementation of the fifth power allocation manner can refer to the related description of the fourth power allocation manner, and will not be described here.

[0158] Based on the fifth power allocation manner described above, the main lobe width of the ambiguity function of the signal can be relatively narrow and the peak side lobe can be relatively low, while the distortion of the signal is relatively small, thereby realizing a better compromise between the perception accuracy / perception resolution, the false alarm rate and the spectrum efficiency, that is, while ensuring the perception accuracy / perception resolution, a lower false alarm rate and a higher spectrum efficiency can be ensured. Therefore, the fifth power allocation manner can also be referred to as a power allocation manner for compromising the perception accuracy / resolution, the false alarm rate and the spectrum efficiency.

[0159] 6. A sixth power allocation manner:

[0160] The sixth power allocation manner includes: the power corresponding to the frequency domain resource unit is related to the channel quality corresponding to the frequency domain resource unit. For example, the channel quality corresponding to the frequency domain resource unit can be understood as: the quality of the channel that the frequency domain resource unit will experience.

[0161] As a possible implementation, the power corresponding to a frequency domain resource unit is positively correlated with the channel quality corresponding to the frequency domain resource unit. For example, if the channel quality corresponding to a frequency domain resource unit is better, the power corresponding to the frequency domain resource unit is larger; if the channel quality corresponding to a frequency domain resource unit is worse, the power corresponding to the frequency domain resource unit is smaller or 0.

[0162] For example, if the bandwidth includes 6 frequency domain resource units, and the 6 frequency domain resource units are sequentially numbered as #1-#6 in the order of frequency from low to high, and the channel quality corresponding to the 6 frequency domain resource units satisfies: frequency domain resource unit #4>frequency domain resource unit #6>frequency domain resource unit #5=frequency domain resource unit #2>frequency domain resource unit #1>frequency domain resource unit #3, the power corresponding to the 6 frequency domain resource units can be as shown in FIG. 8. Referring to FIG. 8, the power corresponding to frequency domain resource unit #4>the power corresponding to frequency domain resource unit #6>the power corresponding to frequency domain resource unit #5=frequency domain resource unit #2>frequency domain resource unit #1>frequency domain resource unit #3.

[0163] Based on the sixth power allocation mode, a higher power is allocated to a frequency domain resource unit with better channel quality based on the channel quality corresponding to the frequency domain resource unit, which can improve the spectrum efficiency. Therefore, the sixth power allocation mode can also be referred to as a power allocation mode with high spectrum efficiency.

[0164] In a possible implementation, each power allocation mode can correspond to at least one power allocation coefficient set. The power allocation coefficient set includes a plurality of power allocation coefficients, and the power allocation coefficient can be used to determine the power corresponding to the frequency domain resource unit. The power allocation coefficient is a real number.

[0165] It can be understood that, in the case that a power allocation mode corresponds to a plurality of power allocation coefficient sets, it is indicated that a plurality of power combinations can be determined based on the power allocation mode. Subsequently, a suitable power combination can be selected from the plurality of power combinations according to actual conditions.

[0166] Optionally, the plurality of power allocation coefficients included in the power allocation coefficient set correspond to the plurality of frequency domain resource units one by one, and each power allocation coefficient represents the relative value of the power allocated to the frequency domain resource unit corresponding to the power allocation coefficient.

[0167] For example, with the power allocation coefficient set {1, 0.8, 0.6, 0.6, 0.8, 1}, the 6 power allocation coefficients in the power allocation coefficient set respectively correspond to the frequency domain resource unit #1 to the frequency domain resource unit #6, which means that the ratio of the power corresponding to the frequency domain resource unit #1 to the power corresponding to the frequency domain resource unit #2 is 1:0.8, the ratio of the power corresponding to the frequency domain resource unit #1 to the power corresponding to the frequency domain resource unit #3 is 1:0.6, the ratio of the power corresponding to the frequency domain resource unit #2 to the power corresponding to the frequency domain resource unit #3 is 0.8:0.6, and so on.

[0168] Optionally, the power allocation coefficient set corresponding to each power allocation mode can be pre-defined by a protocol or determined by the RAN node, which is not limited in the present application.

[0169] Optionally, the absolute value of the power corresponding to each frequency domain resource unit can be determined according to the total transmission power of the signal and the power allocation coefficient set corresponding to a certain power allocation mode. For example, with the power allocation coefficient set {1, 0.8, 0.6, 0.6, 0.8, 1}, the 6 power allocation coefficients in the power allocation coefficient set respectively correspond to the frequency domain resource unit #1 to the frequency domain resource unit #6, and if the total transmission power is P, the powers corresponding to the frequency domain resource unit #1 to the frequency domain resource unit #6 are respectively:

[0170] The power allocation mode provided by the present application is described above. The method provided by the present application is introduced below. As shown in FIG. 9, the method includes the following steps:

[0171] S901, the RAN node determines a power allocation mode corresponding to a first signal. The first signal is a reference signal, or the first signal is a signal carried in a data channel or a control channel.

[0172] As a possible implementation, when the first signal is a reference signal, the first signal can be a sensing dedicated reference signal, and at this time, the first signal is used for sensing. Or, the first signal can be a communication reference signal, at this time, the first signal can be used for communication, not for sensing, or the first signal can be used for communication and sensing. In the case where the first signal is used for communication and sensing, the first signal can be referred to as a communication-sensing fusion signal.

[0173] As a possible implementation, when the first signal is a signal carried in a data channel or a control channel, the first signal can be used for communication, not for sensing, at this time, the first signal can be referred to as a communication signal; or, the first signal can be used for communication and sensing, at this time, the first signal can be referred to as a communication-sensing fusion signal.

[0174] The power allocation manner corresponding to the first signal is used to determine the power corresponding to the frequency domain resource units in the first bandwidth. The first bandwidth is a bandwidth occupied by the first signal, or is a bandwidth scheduled by the RAN node for carrying the first signal.

[0175] The power allocation manner corresponding to the first signal is one of at least two power allocation manners. The at least two power allocation manners include at least one of the first power allocation manner, the second power allocation manner, the third power allocation manner, the fourth power allocation manner, the fifth power allocation manner, or the sixth power allocation manner. The implementation of the six power allocation manners can refer to the related description described above, wherein the bandwidth in the foregoing description is replaced by the first bandwidth for understanding, and details are not described herein.

[0176] Optionally, the at least two power allocation manners described above can be referred to as (or constitute) a power allocation manner set. The power allocation manner set includes at least one of the six power allocation manners (the first power allocation manner to the sixth power allocation manner) described above. In addition, the power allocation manner set can also include other power allocation manners in addition to the six power allocation manners described above. The other power allocation manners can be, for example, the uniform power allocation manner as shown in FIG. 1, or can be other new power allocation manners, which are not limited.

[0177] As an example, the power allocation manner set includes at least one of the six power allocation manners described above, including that the power allocation manner set includes at least two of the at least six power allocation manners described above. In addition, the power allocation manner set does not include other power allocation manners in addition to the six power allocation manners described above.

[0178] For example, the power allocation manner set can include the first power allocation manner and the second power allocation manner; or can include the first power allocation manner and the third power allocation manner; or can include the first power allocation manner, the second power allocation manner, and the third power allocation manner; or can include the fourth power allocation manner and the fifth power allocation manner; or can include the fourth power allocation manner, the fifth power allocation manner, and the sixth power allocation manner.

[0179] As another example, the power allocation manner set includes at least one of the six power allocation manners described above, including that the power allocation manner set includes at least two of the at least six power allocation manners described above. In addition, the power allocation manner set also includes other power allocation manners in addition to the six power allocation manners described above.

[0180] For example, the set of power allocation manners can include a first power allocation manner, a second power allocation manner, and other power allocation manners; or can include a first power allocation manner, a third power allocation manner, and other power allocation manners; or can include a fourth power allocation manner, a fifth power allocation manner, and other power allocation manners.

[0181] In a possible implementation, the set of power allocation manners can also be different in the case that the types or functions of the first signals are different.

[0182] For example, in the case that the first signal is an uplink reference signal for sensing, the set of power allocation manners includes at least one of the first power allocation manner or the second power allocation manner; in the case that the first signal is a downlink reference signal for sensing, the set of power allocation manners includes at least one of the second power allocation manner or the third power allocation manner.

[0183] In the case that the first signal is for sensing and is carried on a data channel or a control channel, or the first signal is for communication and is carried on a data channel or a control channel, the set of power allocation manners includes at least one of the fourth power allocation manner, the fifth power allocation manner, or the sixth power allocation manner.

[0184] Further, for different types of signals for sensing and communication, the set of power allocation manners can be the same, but the power allocation coefficients corresponding to the same power allocation manner in the set of power allocation manners can be different. For example, in the case that the first signal is an uplink data signal for sensing and communication, or is a downlink data signal for sensing and communication, the set of power allocation manners includes at least one of the fourth power allocation manner or the fifth power allocation manner, but in the case that the first signal is an uplink data signal for sensing and communication, the fourth power allocation manner corresponds to a first set of power allocation coefficients, and the fifth power allocation manner corresponds to a second set of power allocation coefficients; in the case that the first signal is a downlink data signal for sensing and communication, the fourth power allocation manner corresponds to a third set of power allocation coefficients, and the fifth power allocation manner corresponds to a fourth set of power allocation coefficients. The first set of power allocation coefficients and the third set of power allocation coefficients are different, and the second set of power allocation coefficients and the fourth set of power allocation coefficients are different.

[0185] S902, the RAN node sends indication information to the terminal. Correspondingly, the terminal receives the indication information from the RAN node. The indication information indicates a power allocation manner corresponding to the first signal.

[0186] As a possible implementation, the indication information indicates an index of the power allocation manner corresponding to the first signal. Optionally, the protocol can predefine or the RAN node and the terminal can pre-determine the index of each power allocation manner in the set of power allocation manners and the corresponding set of power allocation coefficients, i.e., determine the correspondence among the power allocation manner index, the power allocation manner, and the set of power allocation coefficients. Based on this, in the case that the RAN node indicates the index of the power allocation manner corresponding to the first signal through the indication information, the terminal can determine the power allocation manner corresponding to the index and the power allocation coefficients according to the pre-determined correspondence.

[0187] For example, the set of power allocation manners includes three power allocation manners, each of which corresponds to a set of power allocation coefficients, the correspondence among the power allocation manner index, the power allocation manner, and the set of power allocation coefficients can be as shown in Table 1.

[0188] Table 1

[0189] Among them, at least one of the power allocation manner 1, the power allocation manner 2, and the power allocation manner 3 belongs to the six power allocation manners provided in the present application.

[0190] For example, in this possible implementation, the indication information can include a first field, and the value of the first field can be understood as the index of the power allocation manner corresponding to the first signal. For example, the first signal corresponds to the power allocation manner 1, the first field can be set to "00", i.e., indicating that the index of the power allocation manner corresponding to the first signal is 0. The terminal can know that the power allocation manner corresponding to the first signal is the power allocation manner 1 based on the correspondence shown in Table 1.

[0191] Optionally, in the case that the power allocation manner corresponding to the first signal corresponds to multiple sets of power allocation coefficients (denoted as the first set of power allocation coefficients), the indication information further indicates a certain set of power allocation coefficients corresponding to the power allocation manner (denoted as the first set of power allocation coefficients), which can be understood as the set of power allocation coefficients finally used to determine the power. That is, the indication information indicates the power allocation manner corresponding to the first signal and the set of power allocation coefficients corresponding to the power allocation manner.

[0192] Exemplarily, the power allocation manner corresponding to the first signal is power allocation manner 1, the power allocation manner 1 corresponds to the power allocation coefficient set 11 and the power allocation coefficient set 12 (i.e., the corresponding relationship is as shown in Table 2), and the indication information can include a first field and a second field. The first field is used to indicate the power allocation manner 1, and the second field is used to indicate the first power allocation coefficient set.

[0193] Table 2

[0194] Based on the above example, assuming that the first power allocation coefficient set is the power allocation coefficient set 11, the value of the second field can be understood as the index of the power allocation coefficient set. The second field can be set to "0", i.e., indicating that the index of the first power allocation coefficient set is 0. The terminal can obtain, based on the corresponding relationship shown in Table 2, that the power allocation manner corresponding to the first signal is the power allocation manner 1, and that the power allocation manner 1 corresponding to the power allocation coefficient set 11 is used this time.

[0195] As another possible implementation, the indication information indicates the power allocation coefficient set corresponding to the power allocation manner corresponding to the first signal. Optionally, all power allocation coefficient sets corresponding to all power allocation manners in the power allocation manner set can be numbered without repetition in advance to determine the corresponding relationship between the index of the power allocation coefficient set, the power allocation coefficient set and the power allocation manner. Subsequently, when the RAN node indicates a certain power allocation coefficient set through the indication information, the terminal can determine the power allocation coefficient set and the power allocation manner corresponding to the power allocation coefficient set according to the corresponding relationship.

[0196] Exemplarily, assuming that the power allocation manner set includes three power allocation manners, and each power allocation manner corresponds to two power allocation coefficient sets, the corresponding relationship between the index of the power allocation coefficient set, the power allocation coefficient set and the power allocation manner can be as shown in Table 3.

[0197] Table 3

[0198] Among them, at least one of the power allocation manner 1, the power allocation manner 2 and the power allocation manner 3 belongs to the six power allocation manners provided in the present application.

[0199] Exemplarily, in the possible implementation, the indication information can comprise a third field. The value of the third field can be understood as an index of the power allocation coefficient set corresponding to the power allocation mode of the first signal. Taking the power allocation coefficient set 1 corresponding to the power allocation mode 1 of the first signal as an example, the third field can be set as "000", that is, indicating that the index of the power allocation coefficient set corresponding to the power allocation mode of the first signal is 0. The terminal can obtain the power allocation mode corresponding to the first signal as the power allocation mode 1 and the corresponding power allocation coefficient set as the power allocation coefficient set 1 based on the correspondence shown in Table 3.

[0200] S903, the terminal transmits or receives the first signal according to the indication information.

[0201] In the first possible implementation, when the terminal is a transmitting end of the first signal, the terminal transmits the first signal according to the indication information. Exemplarily, the terminal can determine the power allocation mode corresponding to the first signal according to the indication information, and then transmit the first signal according to the power allocation mode corresponding to the first signal. For example, the terminal determines the power corresponding to each frequency domain resource unit in the first bandwidth according to the power allocation coefficient set corresponding to the power allocation mode corresponding to the first signal and the total power, and transmits the first signal on the first bandwidth according to the power corresponding to each frequency domain resource unit.

[0202] When the terminal is a transmitting end of the first signal, as a possible implementation, the receiving end of the first signal can be the RAN node in steps S901 and S902. In this scenario, the RAN node receives the first signal according to the power allocation mode corresponding to the first signal. For example, the RAN node receives the first signal by using a receiving algorithm matched with the power allocation mode, so as to improve the receiving performance.

[0203] When the terminal is a transmitting end of the first signal, as another possible implementation, the receiving end of the first signal can be another terminal. For the convenience of description, when the transmitting end and the receiving end of the first signal are both terminals, the transmitting end of the first signal is referred to as a first terminal, and the receiving end of the first signal is referred to as a second terminal.

[0204] Optionally, when the receiving end of the first signal is the second terminal, the RAN node or the first terminal can indicate the power allocation mode corresponding to the first signal to the second terminal. The implementation of the second terminal receiving the first signal can refer to the foregoing related description of the RAN receiving the first signal, which is not described herein again.

[0205] In a second possible implementation, when the terminal is a receiving end of the first signal, the terminal receives the first signal according to the indication information. For example, the terminal can determine the power allocation mode corresponding to the first signal according to the indication information, and then receive the first signal according to the power allocation mode corresponding to the first signal. For example, the terminal receives the first signal by using a receiving algorithm matched with the power allocation mode, so as to improve the receiving performance.

[0206] When the terminal is a receiving end of the first signal, as a possible implementation, the sending end of the first signal can be the RAN node in steps S901 and S902. In this scenario, the RAN node sends the first signal according to the power allocation mode corresponding to the first signal. The implementation of the RAN node sending the first signal can refer to the foregoing related description of the terminal sending the first signal in the first possible implementation, and will not be described here again.

[0207] When the terminal is a receiving end of the first signal, as another possible implementation, the sending end of the first signal can be another terminal. For the convenience of description, when the sending end and the receiving end of the first signal are both terminals, the sending end of the first signal is referred to as a first terminal, and the receiving end of the first signal is referred to as a second terminal.

[0208] Optionally, when the sending end of the first signal is the first terminal, before step S903, the RAN node also needs to indicate the power allocation mode corresponding to the first signal to the first terminal. The implementation of the first terminal sending the first signal can refer to the foregoing related description of the terminal sending the first signal in the first possible implementation, and will not be described here again.

[0209] In a possible implementation, when the first signal is used for sensing, such as when the first signal is a sensing signal or a communication-sensing fusion signal, the receiving end receiving the first signal can also be understood as the receiving end receiving an echo signal of the first signal.

[0210] Optionally, when the first signal is used for sensing, after receiving the first signal, the receiving end of the first signal can process the first signal to determine the position, distance, speed, and the like of the target.

[0211] Based on the power allocation method of the present application, when performing signal transmission, the RAN node can indicate one power allocation mode from at least two power allocation modes, so that the sending and receiving end can determine the power corresponding to each frequency domain resource unit based on the power allocation mode indicated by the RAN node, and then transmit or receive the signal according to the power corresponding to each frequency domain resource unit. Since the present application provides multiple power allocation modes, the RAN node can flexibly select the power allocation mode suitable for the current signal transmission, improve the flexibility and rationality of power allocation, and then improve the sensing performance and / or communication performance based on the reasonable power allocation.

[0212] In a possible implementation, the frequency domain resource unit can also be understood as a power allocation granularity, and the size of the frequency domain resource unit can be understood as the size of the power allocation granularity. The RAN node can indicate the power allocation granularity in addition to indicating the power allocation manner. For the convenience of description, the indication information indicating the power allocation manner is referred to as first indication information, and the information indicating the power allocation granularity is referred to as second indication information. That is, before step S903, the RAN node can send the second indication information, and the terminal receives the second indication information accordingly. The second indication information indicates the power allocation granularity corresponding to the first signal.

[0213] The power allocation granularity corresponding to the first signal is one of at least two power allocation granularities. The at least two power allocation granularities include at least one of a subcarrier, a subcarrier group (SCG), a resource block (RB), and a resource block group. That is, the power allocation can be performed in the granularity of a subcarrier, a subcarrier group, a resource block, or a resource block group.

[0214] As a possible implementation, the power allocation granularity corresponding to the first signal can be understood as a frequency domain power allocation granularity. The subcarrier, the subcarrier group, the resource block, and the resource block group can also be understood as types of power allocation granularities.

[0215] As a possible implementation, the subcarrier can be understood as the smallest granularity of the frequency domain resource. For example, in an orthogonal frequency division multiplexing (OFDM) system, the frequency domain resource can be divided into a plurality of sub-resources, and each sub-resource on the frequency domain can be referred to as a subcarrier.

[0216] Optionally, the interval between the center positions or peak positions of two adjacent subcarriers on the frequency domain can be referred to as a subcarrier interval. For example, the subcarrier interval in the LTE system is 15 kHz, and the subcarrier interval in the NR system can be 15 kHz, 30 kHz, 60 kHz, 120 kHz, or the like.

[0217] As a possible implementation, one subcarrier group includes at least two subcarriers. For example, the number of subcarriers included in one subcarrier group can be 2, 3, 4, 6, or the like. Of course, the number of subcarriers included in one subcarrier group can also be other values, which are not limited in the present application.

[0218] As a possible implementation, one resource block includes a plurality of subcarriers which are continuous in frequency domain. For example, in LTE system and NR system, one resource block includes 12 subcarriers. It can be understood that with the evolution of communication technology and communication system, the number of subcarriers included in one resource block can also be other values, for example, can be 10, 14 or 16, of course, can also be other values, which are not limited in the present application.

[0219] Optionally, the number of subcarriers included in one subcarrier group is different from the number of subcarriers included in one resource block. For example, the number of subcarriers included in one subcarrier group is less than the number of subcarriers included in one resource block.

[0220] As a possible implementation, the resource block group can also be referred to as RG. One resource block group includes at least two resource blocks.

[0221] Optionally, the at least two power allocation granularities can be referred to as (or composed of) a power allocation granularity set. The power allocation granularity set includes at least one of the above four power allocation granularities (i.e. subcarrier, subcarrier group, resource block, resource block group). In addition, the power allocation granularity set can also include other power allocation granularities in addition to the above four power allocation granularities.

[0222] As a possible implementation, the RAN node can determine the power allocation granularity corresponding to the first signal according to the size of the first bandwidth, for example, there is an association relationship between the size of the first bandwidth and the power allocation granularity corresponding to the first signal. For example, in the case of a larger first bandwidth, the type of the power allocation granularity corresponding to the first signal is a resource block or a resource block group; in the case of a smaller first bandwidth, the type of the power allocation granularity corresponding to the first signal is a subcarrier or a subcarrier group.

[0223] As another possible implementation, the RAN node can determine the power allocation granularity corresponding to the first signal according to the signal type of the first signal, for example, there is an association relationship between the signal type of the first signal and the power allocation granularity corresponding to the first signal. Wherein, the signal type of the first signal can include at least one of the following: reference signal, signal carried in data signal, or signal carried in control channel. For example, when the first signal is a signal carried in a data channel or a control channel, the power allocation granularity corresponding to the first signal is larger; when the first signal is a reference signal, the power allocation granularity corresponding to the first signal is smaller.

[0224] For example, the second indication information can be implemented in the following four ways:

[0225] Method one, the second indication information indicates the type of the power allocation granularity corresponding to the first signal.

[0226] As a possible implementation, the second indication information can be carried in the first field. A plurality of values of the first field correspond to a plurality of power allocation granularity types one by one. For example, the plurality of power allocation granularity types can be at least two of subcarrier, subcarrier group, resource block and resource block group.

[0227] As a first example, when the plurality of power allocation granularity types include subcarrier, subcarrier group, resource block and resource block group, the correspondence between the value of the first field and the power allocation granularity type can be as shown in Table 4.

[0228] Table 4

[0229] That is, when the first field is set to the first value, the type of the power allocation granularity corresponding to the first signal is subcarrier; or, when the first field is set to the second value, the type of the power allocation granularity corresponding to the first signal is subcarrier group; or, when the first field is set to the third value, the type of the power allocation granularity corresponding to the first signal is resource block; or, when the first field is set to the fourth value, the type of the power allocation granularity corresponding to the first signal is resource block group.

[0230] For example, the first value, the second value, the third value and the fourth value can be 0, 1, 2 and 3 respectively. Of course, the first value, the second value, the third value and the fourth value can also have other values, for example, the first value, the second value, the third value and the fourth value can be 3, 2, 1 and 0 respectively, or 3, 1, 2 and 0 respectively, or 0, 2, 1 and 3 respectively, without limitation.

[0231] As a second example, when the plurality of power allocation granularity types include three of subcarrier, subcarrier group, resource block or resource block group, the correspondence between the value of the first field and the power allocation granularity type can be as shown in at least one of Table 5 to Table 8.

[0232] Table 5

[0233] Table 6

[0234] Table 7

[0235] Table 8

[0236] For example, the first value, the second value and the third value can be 0, 1 and 2 respectively. Of course, the first value, the second value and the third value can also have other values, for example, 1, 2 and 3 respectively, or 2, 1 and 0 respectively, or 3, 2 and 1 respectively, without limitation.

[0237] As a third example, when the plurality of power allocation granularity types include two of subcarrier, subcarrier group, resource block or resource block group, the correspondence between the value of the first field and the power allocation granularity type can be as shown in at least one of Table 9 to Table 14.

[0238] Table 9

[0239] Table 10

[0240] Table 11

[0241] Table 12

[0242] Table 13

[0243] Table 14

[0244] Exemplarily, the first value and the second value can be 0 and 1 respectively. Of course, the first value and the second value can also have other values, for example, 1 and 0 respectively, without limitation.

[0245] As a possible implementation, in the first mode, the size of the power allocation granularity can be 1 power allocation granularity or multiple power allocation granularities. For example, when the power allocation granularity is a subcarrier, the size of the power allocation granularity can be 1 subcarrier or multiple subcarriers; when the power allocation granularity is a resource block, the size of the power allocation granularity can be 1 resource block or multiple resource blocks. Exemplarily, the size of the power allocation granularity can be predetermined by a protocol, or can be indicated in advance by a RAN node, or can be preset.

[0246] In the second mode, the second indication information indicates the value of the power allocation granularity corresponding to the first signal. The value of the power allocation granularity can also be understood as the size of the power allocation granularity.

[0247] As a possible implementation, in this mode, the type of the power allocation granularity can be predetermined by a protocol, or can be indicated in advance by a RAN node, for example, the type of the power allocation granularity can be indicated by the above-mentioned first mode, or can be preset. For example, the protocol can agree that the type of the power allocation granularity is one of subcarrier, subcarrier group, resource block or resource block group.

[0248] For example, if the power allocation granularity type is a resource block, one resource block includes 12 subcarriers, and the second indication information indicates a value of 2, it means that the power allocation granularity is 2 resource blocks; if the second indication information indicates a value of 1, it means that the power allocation granularity is 1 resource block; if the second indication information indicates a value of 1 / 2, it means that the power allocation granularity is 1 / 2 resource block, i.e., 6 subcarriers; if the second indication information indicates a value of 1 / 6, it means that the power allocation granularity is 1 / 6 resource block, i.e., 2 subcarriers; if the second indication information indicates a value of 1 / 12, it means that the power allocation granularity is 1 / 12 resource block, i.e., 1 subcarrier.

[0249] As a possible implementation, the second indication information indicating the value of the power allocation granularity corresponding to the first signal can include that the second indication information includes the value of the power allocation granularity corresponding to the first signal, for example, the second indication information is carried in the second field, and the value of the second field is the value of the power allocation granularity corresponding to the first signal.

[0250] Alternatively, the second indication information indicating the value of the power allocation granularity corresponding to the first signal can include that the second indication information is carried in the second field, and the value of the second field is in an associated relationship with the value of the power allocation granularity corresponding to the first signal. For example, the associated relationship can be as shown in Table 15.

[0251] Table 15

[0252] For example, the first value, the second value, the third value, and the fourth value can be 0, 1, 2, and 3 respectively. Of course, the first value, the second value, the third value, and the fourth value can also have other values, for example, the first value, the second value, the third value, and the fourth value can be 3, 2, 1, and 0 respectively, or 3, 1, 2, and 0 respectively, or 0, 2, 1, and 3 respectively, without limitation.

[0253] In the third mode, there is an associated relationship between the number of resource blocks occupied by the signal and the power allocation granularity, and the second indication information indicates the number of resource blocks occupied by the first signal. The associated relationship between the number of resource blocks occupied by the signal and the power allocation granularity includes the associated relationship between the number of resource blocks occupied by the first signal and the power allocation granularity corresponding to the first signal.

[0254] As a possible implementation, the number of resource blocks occupied by the first signal can be scheduled by the RAN node. The associated relationship between the number of resource blocks occupied by the signal and the power allocation granularity can be defined by the protocol or can be pre-configured by the RAN node, without limitation.

[0255] As a possible implementation, the association between the number of resource blocks occupied by the signal and the power allocation granularity can include at least one of the following shown in Table 16.

[0256] Table 16

[0257] That is, the association between the number of resource blocks occupied by the signal and the power allocation granularity can include at least one of the following: when the number of RBs occupied by the signal is greater than or equal to a fifth value, the power allocation granularity is 2 RBs; when the number of RBs occupied by the signal is less than the fifth value and greater than or equal to a sixth value, the power allocation granularity is 1 RB; when the number of RBs occupied by the signal is less than the sixth value and greater than or equal to a seventh value, the power allocation granularity is 0.5 RB; and when the number of RBs occupied by the signal is less than the seventh value, the power allocation granularity is 1 subcarrier.

[0258] For example, the fifth value, the sixth value, and the seventh value can be 50, 25, and 10, respectively. Of course, the fifth value, the sixth value, and the seventh value can also have other values, such as 60, 35, and 20, respectively, and the application does not limit the specific values of the fifth value, the sixth value, and the seventh value.

[0259] For example, when the fifth value, the sixth value, and the seventh value are 50, 25, and 10, respectively, the association between the number of resource blocks occupied by the signal and the power allocation granularity can include at least one of the following shown in Table 17.

[0260] Table 17

[0261] Based on the example shown in Table 17, if the number of RBs occupied by the first signal is greater than or equal to 50, the power allocation granularity corresponding to the first signal is 2 RBs; if the number of RBs occupied by the first signal is less than 50 and greater than or equal to 25, the power allocation granularity corresponding to the first signal is 1 RB; if the number of RBs occupied by the first signal is less than 25 and greater than or equal to 10, the power allocation granularity corresponding to the first signal is 0.5 RB; and if the number of RBs occupied by the first signal is less than 10, the power allocation granularity corresponding to the first signal is 1 subcarrier.

[0262] It should be noted that in the association shown in Table 16, the case where X is equal to a certain value and the case where X is greater than a certain value are described as parallel cases. In addition, the case where X is equal to a certain value and the case where X is less than a certain value can also be described as parallel cases. For example, the association between the number of resource blocks occupied by the signal and the power allocation granularity can also include at least one of the following shown in Table 18.

[0263] Table 18

[0264] In this way three, the power allocation granularity corresponding to the first signal can be determined based on the number of resource blocks occupied by the first signal. Since the RAN node needs to schedule resource blocks to transmit the first signal when the first signal is transmitted, the scheduling information of the first signal can be reused to indicate the power allocation granularity corresponding to the first signal, thereby saving signaling overhead.

[0265] It should be noted that in this way three, the resource block can also be replaced by other resource units in the frequency domain, such as resource block groups, that is, there is a correlation between the number of resource block groups occupied by the signal and the power allocation granularity. This correlation can be defined by a protocol or can be configured by the RAN node, which is not limited.

[0266] In way four, there is a correlation between the signal type of the signal and the power allocation granularity, and the second indication information indicates the signal type of the first signal. The correlation between the signal type of the signal and the power allocation granularity includes the correlation between the signal type of the first signal and the power allocation granularity corresponding to the first signal.

[0267] As a possible implementation, the signal type of the signal includes at least one of the following: a reference signal, a signal carried in a data channel, or a signal carried in a control channel. Further, the reference signal can be divided into a reference signal for sensing and communication, a reference signal for sensing but not for communication (also known as a sensing dedicated reference signal or a sensing signal).

[0268] As a possible implementation, the correlation between the signal type of the signal and the power allocation granularity can include at least one of the following shown in Table 19.

[0269] Table 19

[0270] That is, the correlation between the signal type of the signal and the power allocation granularity can include at least one of the following: when the signal type is a signal carried in a data channel or a control channel, the power allocation granularity is 2 RBs; when the signal type is a reference signal and the reference signal is used for sensing and communication, the power allocation granularity is 1 RB; when the signal type is a reference signal and the signal is dedicated for sensing, the power allocation granularity is 0.5 RB.

[0271] In this way four, as a possible implementation, the signal type of the first signal transmitted or received by the terminal in the above step S903 is the signal type indicated by the second indication information.

[0272] In this way, the fourth mode can determine the power allocation granularity corresponding to the first signal based on the signal type of the first signal. Since the RAN node can indicate the signal type of the first signal when scheduling the transmission of the first signal, the scheduling information of the first signal can be reused to indicate the power allocation granularity corresponding to the first signal, thereby saving signaling overhead.

[0273] It should be noted that the above four modes can be used independently or in combination. For example, mode one and mode two can be combined to indicate the type and size of the power allocation granularity. Mode three and mode four can also be combined, for example, the number of resource blocks occupied by the signal and the signal type of the signal are used to indicate the power allocation granularity. Of course, there can be other combinations, which are not limited by the present application.

[0274] In a possible implementation, in the case where the RAN node also sends the second indication information, in step S903, the terminal transmits or receives the first signal according to the first indication information and the second indication information. For example, the terminal determines the power corresponding to each frequency domain resource unit in the first bandwidth according to the power allocation coefficient corresponding to the power allocation manner corresponding to the first signal and the total power, the size of the frequency domain resource unit is the size of the power allocation granularity indicated by the second indication information, and the type of the frequency domain resource unit is the type of the power allocation granularity indicated by the second indication information.

[0275] Based on the above scheme, when transmitting a signal, the RAN node can indicate one power allocation granularity from at least two power allocation granularities, so that the transceiver can determine the power corresponding to each subcarrier in the bandwidth occupied by the signal based on the power allocation granularity indicated by the RAN node, and then transmit or receive the signal according to the power corresponding to each subcarrier. Since the present application provides multiple power allocation granularities, the RAN node can flexibly select the power allocation granularity suitable for the current signal transmission, thereby improving the flexibility and rationality of power allocation, and improving the sensing performance and / or communication performance based on reasonable power allocation.

[0276] The above describes the method provided by the present application, in addition, the present application also provides a communication device for implementing the functions described in the above method embodiments.

[0297] In this application, the communication device 100 can be presented in the form of an integrated manner to divide each function module. The "module" here can refer to a specific application-specific integrated circuit (ASIC), a circuit, a processor and a memory executing one or more software or firmware programs, an integrated logic circuit, and / or other devices that can provide the above functions.

[0298] In some embodiments, when the communication apparatus 100 in FIG. 10 is a chip or a chip system, the function / implementation process of the transceiver module 1002 can be implemented through the input / output interface (or the communication interface) of the chip or the chip system, and the function / implementation process of the processing module 1001 can be implemented through the processor (or the processing circuit) of the chip or the chip system.

[0299] Since the communication apparatus 100 provided by the embodiment can execute the above method, the technical effects that can be obtained by the communication apparatus 100 can refer to the above method embodiments, which will not be described here.

[0301] As another possible product form, the RAN node or the terminal described in the embodiments of the present application can be implemented by a general bus architecture. For ease of illustration, refer to FIG. 11, which is a structural schematic diagram of a communication apparatus 1100 provided by the embodiments of the present application, the communication apparatus 1100 including a processor 1101 and a transceiver 1102. The communication apparatus 1100 can be a RAN node, or a chip or a chip system therein; or the communication apparatus 1100 can be a terminal, or a chip or a module therein. FIG. 11 only shows the main components of the communication apparatus 1100. In addition to the processor 1101 and the transceiver 1102, the communication apparatus can further include a memory 1103 and an input / output device (not shown in the figure).
