[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on March 6, 2024, with application number 202410259931.7 and application name “A method for determining aggregate bandwidth and corresponding device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a method for determining aggregate bandwidth and a corresponding device. Background Art

[0003] In integrated communication and perception systems, terminal devices or network equipment can use radio wave transmission, reflection, and scattering to perceive and characterize their environment, enabling high-precision positioning and tracking, as well as gesture and activity recognition. In some communication or perception scenarios, there is a significant demand for communication bandwidth, leading to the use of aggregated bandwidth.

[0004] Currently, aggregate bandwidth refers to the bandwidth consisting of portions of the bandwidth of contiguous intra-band carriers. Terminal devices can receive positioning reference signals (PRS) or send sounding reference signals (SRS) on the aggregate bandwidth configured by network equipment.

[0005] Current aggregate bandwidth configuration methods do not work well in certain scenarios. Summary of the Invention

[0006] The present application provides a method for determining an aggregate bandwidth, which is used to determine an aggregate bandwidth that meets perceived performance requirements and improve resource utilization of a communication system. The present application also provides a corresponding apparatus, a computer-readable storage medium, and a computer program product.

[0007] In a first aspect, the present application provides a method for determining an aggregate bandwidth, which is applied to a first device. The method includes: receiving first information sent by a second device, the first information including a perception performance requirement and information about at least one aggregate bandwidth, each of the at least one aggregate bandwidth being used to transmit a perception reference signal or channel; determining second information based on the first information, the second information including information about the first aggregate bandwidth, the first aggregate bandwidth being an aggregate bandwidth that meets the perception performance requirement among the at least one aggregate bandwidth; and sending the second information to the second device.

[0008] In this application, aggregate bandwidth refers to a transmission resource with a larger bandwidth formed by combining component bandwidths on different carriers.

[0009] In this application, there may be one or more first aggregate bandwidths. If at least one aggregate bandwidth in the first information does not include a first aggregate bandwidth that meets the perceived performance requirement, the first device only needs to provide feedback indicating the aggregate bandwidth that does not meet the perceived performance requirement. The second device may then send information about other aggregate bandwidths until the first device determines that a first aggregate bandwidth that meets the perceived performance requirement is found.

[0010] In this application, the sensing performance requirement refers to the requirement that a sensing reference signal (SERS) or a sensing signal or a sensing channel configured with aggregated bandwidth needs to meet for a given sensing performance.

[0011] The first device may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method for determining aggregate bandwidth, such as a chip. Exemplarily, the first device is a terminal device / network device (e.g., a base station), or a chip provided in the terminal device / network device for implementing the functions of the terminal device / network device, or other components for implementing the functions of the terminal device / network device. It should be noted that the first device may also be a dedicated sensing device.

[0012] The second device can be a communications device or a communications device capable of supporting the communications device in implementing the functions required by the method for determining aggregate bandwidth, such as a chip. Exemplarily, the second device is a network device / terminal device, or a chip provided in the network device / terminal device for implementing the functions of the network device / terminal device, or other components for implementing the functions of the network device / terminal device. It should be noted that the second device can also be a dedicated sensing device. If the second device is a network device, it can be a device in the core network or an access network device.

[0013] Using the above method, the first device can screen at least one aggregate bandwidth based on the sensing performance requirement and information about at least one aggregate bandwidth sent by the second device, select a first aggregate bandwidth that meets the sensing performance requirement, and then report the information about the first aggregate bandwidth that meets the sensing performance requirement to the second device. In this way, when the second device subsequently configures an aggregate bandwidth for the first device to transmit a sensing reference signal or channel, it can configure a first aggregate bandwidth that meets the sensing performance requirement, thereby improving resource utilization in the communication system. Furthermore, when the first aggregate bandwidth is used for subsequent transmission of SERS, sensing signals, or sensing channels, it can improve sensing accuracy and / or resolution.

[0014] In a possible implementation, the step of determining the second information based on the first information includes determining, based on capability information of the first device, a first aggregate bandwidth that meets the perceived performance requirement from at least one aggregate bandwidth.

[0015] In the present application, the capability information of the first device may include the sensing capabilities of the first device, such as duplex capability, multi-carrier capability, bandwidth capability, self-sensing capability (e.g., sensing the round trip time (RTT) of a signal), whether it supports aggregated bandwidth, or whether it supports flexible configuration of the gap between the components of the aggregated bandwidth (GAP). The capability information also includes the ability to determine whether the aggregated bandwidth meets the sensing performance requirements under a specific aggregated bandwidth.

[0016] In this possible implementation, the first device may determine the first aggregate bandwidth that meets the perception performance requirement based on its own capability information, thereby saving resources for sending or receiving SERS for determining the first aggregate bandwidth.

[0017] In one possible implementation, the step of determining the second information based on the first information includes: sending a first perception reference signal through each aggregated bandwidth of at least one aggregated bandwidth based on the first information; and receiving and measuring each second perception reference signal to obtain the second information, where each second perception reference signal is a reflected signal of the first perception reference signal transmitted through each aggregated bandwidth.

[0018] In the present application, the reflected signal may be a signal that is reflected by the first target after the first perception reference signal encounters the first target, and the reflected signal may also be an echo signal.

[0019] In this possible implementation, the first device can determine information about the first aggregate bandwidth that meets the sensing performance requirements through self-sensing (the first device transmits a first SERS signal, receives a reflected second SERS signal, and measures the second SERS signal). Determining the first aggregate bandwidth through self-sensing can improve the accuracy of determining the first aggregate bandwidth.

[0020] In one possible implementation, the step of determining the second information based on the first information includes: receiving, based on the first information, a third perception reference signal sent by the second device from each aggregated bandwidth of at least one aggregated bandwidth; and measuring each third perception reference signal to obtain the second information.

[0021] In this possible implementation, the first device may determine the first aggregate bandwidth by measuring the third SERS sent by the second device, which may improve the accuracy of determining the first aggregate bandwidth.

[0022] In one possible implementation, the information of the second aggregate bandwidth includes two items of the frequency starting position, the frequency ending position, or the bandwidth value of the first component bandwidth, and two items of the frequency starting position, the frequency ending position, or the bandwidth value of the second component bandwidth. The first component bandwidth is located on the first carrier, the second component bandwidth is located on the second carrier, and the second aggregate bandwidth is any one of the at least one aggregate bandwidth.

[0023] In this possible implementation, because the second device can flexibly configure two of the frequency start position, frequency end position, or bandwidth value of each component bandwidth when configuring at least one aggregate bandwidth, the gap (GAP) between each two component bandwidths can be flexible. A flexible GAP can improve the flexibility of the aggregate bandwidth.

[0024] In one possible implementation, the frequency of the first carrier is less than the frequency of the second carrier, and the interval between the first component bandwidth and the second component bandwidth is: the difference between the distance between the frequency starting position of the first component bandwidth and the frequency ending position of the second component bandwidth and the bandwidth value of the first component bandwidth and the bandwidth value of the second component bandwidth; or, the difference between the distance between the frequency starting position of the first component bandwidth and the frequency starting position of the second component bandwidth and the bandwidth value of the first component bandwidth; or, the difference between the distance between the frequency ending position of the first component bandwidth and the frequency ending position of the second component bandwidth and the bandwidth value of the second component bandwidth; or, the frequency ending position of the first component bandwidth and the frequency starting position of the second component bandwidth.

[0025] In this possible implementation, the GAP between two component bandwidths can be calculated based on the frequency start position, frequency end position, and bandwidth value of the component bandwidths, thereby increasing the flexibility of determining the GAP.

[0026] In a possible implementation, the information about the second aggregate bandwidth further includes information about puncture resources, where the information about the puncture resources is used to indicate that the puncture resources in the first carrier and / or the second carrier are not used for transmitting the perception reference signal.

[0027] In this possible implementation, the second aggregate bandwidth information includes puncturing resource information to instruct the first device not to use puncturing resources to send or receive SERS. The puncturing resources can then be used for other data transmissions, thereby improving carrier resource utilization.

[0028] In a possible implementation, the width of the puncturing resource and the guard interval between the first carrier and the second carrier is the interval GAP between the first component bandwidth and the second component bandwidth.

[0029] In this possible implementation, because the puncturing resources are not fixed, the puncturing resources and the guard period (GP) together constitute the GAP between the constituent bandwidths of the aggregated bandwidth, which can improve the flexibility of the GAP. Flexible GAP configuration can support flexible aggregated bandwidth configuration, which is beneficial for the communication system to support various types of services for resource reuse.

[0030] In a possible implementation, the information about the second aggregate bandwidth further includes a pattern in the component bandwidths used to transmit the perception reference signal, and at least two component bandwidths of the second aggregate bandwidth correspond to at least one pattern.

[0031] In this possible implementation, the SERS patterns in different component bandwidths of the second aggregate bandwidth may be the same or different, thereby improving the flexibility of SERS transmission in the aggregate bandwidth.

[0032] In a possible implementation manner, the first information further includes feeding back a maximum amount of the first aggregate bandwidth.

[0033] In this possible implementation, if the number of first aggregate bandwidths determined by the first device to meet the perceived performance requirements is greater than the maximum number in the first information, only the information about the maximum number of first aggregate bandwidths may be fed back. This not only meets the needs of the second device and configures a reasonable aggregate bandwidth, but also reduces the length of the second information, saving resources for transmitting the second information.

[0034] In a possible implementation, the second information further includes a maximum interval GAP value between component bandwidths of the first aggregate bandwidth.

[0035] In this possible implementation, the first device may include the maximum gap value between component bandwidths of the first aggregate bandwidth in the second information. This allows the second device to select appropriate component bandwidths within the maximum gap value range to form an aggregate bandwidth that meets the perceived performance requirements, thereby increasing the flexibility of the second device in configuring the aggregate bandwidth that meets the perceived performance requirements.

[0036] In one possible implementation, the perception performance requirements include a first expected value and a first deviation range of distance resolution; and / or a second expected value and a second deviation range of distance accuracy; wherein the first deviation range is a range of deviation between the distance resolution determined according to the capability of the first device and the first expected value, the second deviation range is a range of deviation between the distance accuracy determined according to the capability of the first device and the second expected value, and the second expected value is an expected value under the signal-to-noise ratio configured for the second device.

[0037] In this possible implementation, the perceived performance requirement includes an expected value and a deviation range of a distance resolution or a distance accuracy, which can improve the flexibility of the first device in determining the first aggregate bandwidth that meets the performance requirement.

[0038] In one possible implementation, the perception performance requirement includes a first value and / or a second value, the first value being used to indicate a value that the distance resolution determined by the first device under the signal-to-noise ratio indicated by the second device must satisfy, and the second value being used to indicate a value that the distance accuracy determined by the first device under the signal-to-noise ratio indicated by the second device must satisfy.

[0039] In this possible implementation, the perception performance requirement includes a value that the distance resolution / distance accuracy must meet, so that the accuracy of the maximum GAP fed back by the first device can be improved.

[0040] In one possible implementation, the information of at least one aggregated bandwidth includes information of a first target, resource information of a first perception reference signal, measurement information, and feedback information. The first target is used to reflect the first perception reference signal, and the resource information includes at least one of information about a waveform of the first perception reference signal, information about resources for transmitting the first perception reference signal, beam information, and transmit power information of the first perception reference signal. The measurement information includes at least one of information about a round-trip time (RTT) from the first perception reference signal to the corresponding second perception reference signal, an angle at which the first perception reference signal is transmitted, an angle at which the second perception reference signal is received, received power of the second perception reference signal, and a signal-to-noise ratio of the second perception reference signal. The feedback information includes resources for feeding back the second information. The perception performance requirement includes at least one of a range of RTT measurement values, a range of received power of the second perception reference signal, or a range of angles at which the second perception reference signal is received.

[0041] In this possible implementation, the second device provides the first device with self-perception resource information, measurement information, feedback information, and perception performance requirements through the first information, so that the first device can perform self-perception measurements more effectively and more accurately determine the first aggregate bandwidth that meets the perception performance requirements.

[0042] In one possible implementation, the information of at least one aggregated bandwidth includes resource information, measurement information, and feedback information of a third perception reference signal; the resource information includes at least one of information about the waveform of the third perception reference signal, information about resources for transmitting the third perception reference signal, beam information, and transmit power information of the third perception reference signal; the measurement information includes at least one of an angle for receiving the third perception reference signal, received power of the third perception reference signal, and a signal-to-noise ratio of the third perception reference signal; the feedback information includes resources for feeding back the second information; and the perception performance requirement includes at least one of a range of a time difference between a transmission time and a reception time of a perception reference signal indicated by the second device to the first device, a range of the received power of the third perception reference signal, and a range of an angle for receiving the third perception reference signal.

[0043] In this possible implementation, the second device provides the first device with resource information, measurement information, feedback information for transmission and reception separation, and perception performance requirements through the first information, so that the first device can more effectively measure the SERS sent by the second device and more accurately determine the first aggregate bandwidth that meets the perception performance requirements.

[0044] In a possible implementation, the first information further includes information about an available aggregate bandwidth for the second target; and the method further includes: performing a perceptual measurement on the second target using the available aggregate bandwidth.

[0045] In the present application, the method of indicating the available aggregate bandwidth may not specifically specify a certain aggregate bandwidth, but rather indicate to select an aggregate bandwidth that meets the perception performance requirements from at least one aggregate bandwidth in the first information sent by the second device to perform perception measurement on the second target, such as: after the first device determines the second information, it can select a first aggregate bandwidth to perform perception measurement on the second target. Or the first device directly selects an aggregate bandwidth that meets the perception performance requirements to perform perception measurement on the second target based on the transmission resources of each aggregate bandwidth configured by the second device in the first information. Regardless of which method is used to select the available aggregate bandwidth, after completing the perception measurement of the second target, the result of the perception measurement of the second target using the aggregate bandwidth can be reported, and the information of the aggregate bandwidth used and / or other aggregate bandwidth that meets the perception performance requirements can also be reported.

[0046] In this possible implementation, the first device can measure the second target (unknown target) based on the available aggregate bandwidth in the first information, without the second device having to wait for the first device to provide feedback on the first aggregate bandwidth before instructing the first device to perform measurement. This reduces the measurement delay for the second target.

[0047] In a possible implementation, the information of the first aggregate bandwidth includes an index and a perception measurement result of the first aggregate bandwidth; or an index and a perception measurement time of the first aggregate bandwidth; or an index, a perception measurement result, and a perception measurement time.

[0048] In the present application, the perception measurement results may include one or more of the RTT measurement value, SERS received signal strength, SERS received signal signal-to-noise ratio or signal-to-interference-plus-noise ratio, transmitted signal angle, received signal angle, beam index, Doppler shift of the received signal, and time difference between a specified transmitted signal and a specified received signal.

[0049] In this possible implementation, the first device may report the perception measurement result or the perception measurement time in the information of the first aggregate bandwidth, so that the second device may obtain more accurate measurement information about the first aggregate bandwidth.

[0050] A second aspect of the present application provides a method for determining an aggregate bandwidth, which is applied to a second device communicating with a first device. The method includes: sending first information to the first device, the first information including perceptual performance requirements and information about at least one aggregate bandwidth, each of the at least one aggregate bandwidth being used to transmit a perceptual reference signal or channel; and receiving second information sent by the first device, the second information including information about a first aggregate bandwidth, the first aggregate bandwidth being an aggregate bandwidth that meets the perceptual performance requirements among the at least one aggregate bandwidth.

[0051] In one possible implementation, the information of the second aggregate bandwidth includes two items of the frequency starting position, the frequency ending position, or the bandwidth value of the first component bandwidth, and two items of the frequency starting position, the frequency ending position, or the bandwidth value of the second component bandwidth. The first component bandwidth is located on the first carrier, the second component bandwidth is located on the second carrier, and the second aggregate bandwidth is any one of the at least one aggregate bandwidth.

[0052] In a possible implementation, the information about the second aggregate bandwidth further includes information about puncturing resources, where the information about the puncturing resources is used to indicate that the puncturing resources in the first carrier and / or the second carrier are not used for transmitting the perception reference signal.

[0131] The following describes the embodiments of the present application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present application, rather than all the embodiments. Those skilled in the art will appreciate that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0132] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way are interchangeable where appropriate so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. "At least one" means "one or more". "Sensing reference signal received power (SE-RSRP)" means the RSRP corresponding to the time of sensing.

[0133] Embodiments of the present application provide a method for determining an aggregate bandwidth that meets perceived performance requirements, thereby improving resource utilization in a communication system. This application also provides corresponding apparatus, computer-readable storage media, and computer program products, among others. These are described in detail below.

[0134] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: satellite communication, fifth generation (5G) system or new radio (NR), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), universal mobile telecommunication system (UMTS), mobile communication systems after 5G networks (for example, 6G mobile communication systems), vehicle to everything (V2X) communication systems, etc.

[0135] In addition to having stronger communication capabilities, the above-mentioned communication system also has perception capabilities. It is a communication system with integrated communication and perception. A communication system with integrated communication and perception means that the communication system can communicate through communication signals (communication signals can also be described as communication channels) and can also perform perception measurements through perception signals (perception signals can also be described as perception channels).

[0136] In this application, "perception" refers to the use of radio wave transmission, reflection, and scattering to perceive the surrounding environment and detect targets, such as sensing other vehicles or objects around them through sensing signals in the Internet of Vehicles. Of course, the communication system of this application can also be an industrial automation system or other communication system that involves perception.

[0137] The communication system of the present application may be a communication system based on orthogonal frequency division multiplexing (OFDM) and / or time division multiplexing (TDM), or a communication system or a communication and perception system based on frequency modulated continuous waveform (FMCW).

[0138] The communication system provided in this application can be understood by referring to Figures 1A to 1C.

[0139] As shown in FIG1A , the communication system shown in FIG1A includes a core network, access network equipment, and terminal equipment. The communication system may also include multiple targets, which may be known targets or unknown targets relative to the access network equipment or the terminal equipment. A known target represents a target that has been detected by the access network equipment or the terminal equipment, while an unknown target represents a target that has not been detected by the access network equipment or the terminal equipment.

[0140] In Figure 1A, the core network includes a sensing function (SEF) module. The SEF module can be integrated into existing equipment in the core network or can be an independent device. The SEF module can manage parameter configurations related to perception (such as information on aggregated bandwidth) and can also perform perception calculations based on perception measurement results.

[0141] The SEF module can send the parameter configuration related to perception to the access network device or the terminal device through the target interface. For example, the parameter configuration related to perception can be sent to the access network device through the new radio positioning protocol (NRPP) and sent to the terminal device through the long term evolution positioning protocol (LPP).

[0142] The SEF module can trigger a device in the core network in which the SEF module is integrated to transmit first information containing information about at least one aggregated bandwidth and a perception performance requirement. The first information is then transmitted (e.g., transparently transmitted) to a terminal device via an access network device. The terminal device can determine a first aggregated bandwidth among the at least one aggregated bandwidths that meets the perception performance requirement based on its own capabilities or measurements of a sensing reference signal (SERS), and then report the first aggregated bandwidth information to the access network device or a device in the core network. In this way, the access network device or a device in the core network can transmit the SERS based on the first aggregated bandwidth that meets the perception performance requirement, thereby improving resource utilization of the communication system. Furthermore, when the first aggregated bandwidth is used for subsequent SERS transmission, perception accuracy and / or resolution can be improved.

[0143] As shown in FIG1B , the communication system shown in FIG1B includes an access network device and a terminal device. The communication system may further include multiple targets, which may be known targets or unknown targets relative to the access network device or the terminal device.

[0144] In Figure 1B, an access network device is integrated with an SEF module. The access network device can transmit first information to the terminal device via the Uu interface between the access network device and the terminal device. The terminal device can then determine a first aggregate bandwidth that meets the perceptual performance requirements based on its own capabilities or measurements of the perceptual SERS, and then report the first aggregate bandwidth information to the access network device. This allows the access network device to transmit SERS based on the first aggregate bandwidth that meets the perceptual performance requirements, thereby improving resource utilization in the communication system. Furthermore, when the first aggregate bandwidth is used for subsequent SERS transmission, it can improve perceptual accuracy and / or perceptual resolution.

[0145] As shown in FIG1C , the communication system includes multiple terminal devices (a vehicle is used as an example in FIG1C ). The communication system may also include multiple targets, which may be known targets or unknown targets relative to the access network device or the terminal device. A known target is a target that has been detected by the terminal device, and an unknown target is a target that has not yet been detected by the terminal device.

[0146] In Figure 1C, a terminal device may be integrated with an SEF module. The terminal device integrated with the SEF module may send perception-related parameter configurations (such as first information) to other terminal devices via a sidelink. The terminal device that receives the first information may determine a first aggregate bandwidth that meets the perception performance requirements based on its own capabilities or measurements of the perception SERS, and then report the information of the first aggregate bandwidth to the access network device or use it for resource scheduling (e.g., based on a listen before talk (LBT) mechanism). In this way, the terminal device integrated with the SEF module may transmit SERS based on the first aggregate bandwidth that meets the perception performance requirements, thereby improving the resource utilization of the communication system. Moreover, when the first aggregate bandwidth is used for subsequent transmission of SERS, the perception accuracy and / or perception resolution may be improved.

[0147] The communication systems introduced in Figures 1A to 1C above are each configured with only one SEF module. It should be noted that multiple SEF modules may also be configured in the communication system. For example, in Figure 1A, the SEF module is not only configured in the core network device, but also in the access network device and / or terminal device, or a special device for configuring the SEF module may be deployed in the communication system. Only one of these SEF modules may be started for perception management, or different SEF modules may be started at different times for perception management, or the SEF module used for perception management may be determined by other means, for example, the SEF module used for perception management may be determined by the device in the core network or the access network device.

[0148] In addition, in the communication systems illustrated in Figures 1A to 1C above, the perception measurement process is performed by the terminal device. In practice, the perception measurement process can also be performed by the access network device. When the perception measurement process is performed by the access network device, a device with an integrated SEF module in the core network or a dedicated SEF device can interact with the access network device to complete the perception measurement process by exchanging the above-mentioned information about aggregate bandwidth.

[0149] The following is an introduction to the terminal equipment and access network equipment of this application.

[0150] A terminal device can be a device capable of receiving core network information or access network device scheduling and instruction information. A wireless terminal device can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem or a device with sensing capabilities.

[0151] Terminal devices, also known as user equipment (UE), mobile stations (MS), or mobile terminals (MT), are devices that include wireless communication capabilities and / or sensing capabilities (providing voice / data connectivity to users), such as handheld devices or in-vehicle devices with wireless connectivity. Currently, some examples of terminal devices include: mobile phones, tablets, laptops, PDAs, drones, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in the Internet of Vehicles, wireless terminals in self-driving cars, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. For example, wireless terminals in the Internet of Vehicles (IoV) can be in-vehicle devices, complete vehicle equipment, in-vehicle modules, and vehicles. Wireless terminals in industrial control can be cameras and robots. Wireless terminals in smart homes can be televisions, air conditioners, sweepers, speakers, and set-top boxes.

[0152] Access network equipment is a device deployed in a radio access network (RAN) that provides wireless communication and / or awareness capabilities for terminal devices. For example, an access network device may be a radio access network (RAN) node that connects a terminal device to a wireless network. An access network device may also be a device deployed in a RAN that can communicate with other access network devices and provide wireless communication and / or awareness capabilities between access network devices.

[0153] Access network equipment includes but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (for example, home evolved NodeB, or home Node B, HNB), baseband unit (BBU), access point (AP) in wireless fidelity (WIFI) system, wireless relay node, wireless backhaul node, transmission point (TP) or transmission and reception point (TRP), etc., and can also be access network equipment in 5G mobile communication system. For example, a next-generation NodeB (gNB), a transmission reception point (TRP), or a transmission point (TP) in a new radio (NR) system; or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system; or access network equipment can also be a network node that constitutes a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DU).

[0154] In some deployments, a gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU). The CU implements some gNB functions, while the DU implements some gNB functions. For example, the CU is responsible for processing non-real-time protocols and services, implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, implementing the functions of the radio link control (RLC), media access control (MAC), and physical (PHY) layers. The AAU implements some physical layer processing functions, RF processing, and active antenna-related functions. RRC layer information ultimately becomes PHY layer information, or is converted from PHY layer information. Therefore, in this architecture, higher-layer signaling (such as RRC layer signaling) can also be considered to be sent by the DU, or by both the DU and the AAU. It is understood that the access network equipment can include one or more of a CU node, a DU node, or an AAU node. In addition, the CU may be classified as an access network device in a radio access network (RAN), or may be classified as an access network device in a core network (CN), which is not limited in this application.

[0155] To facilitate understanding of the embodiments of the present application, the following first briefly introduces the terms involved in the present application.

[0156] 1. Orthogonal Frequency Division Multiplexing (OFDM): OFDM is a type of multi-carrier modulation. Its main concept is to divide the channel into several orthogonal sub-channels, converting high-speed data signals into parallel low-speed sub-data streams, and modulating them for transmission on each sub-channel. Orthogonal signals can be separated by using correlation techniques at the receiving end, which can reduce mutual interference between sub-channels (such as inter-subcarrier interference). The signal bandwidth on each sub-channel is smaller than the correlation bandwidth of the channel, so each sub-channel can be viewed as flat fading, thereby eliminating inter-symbol interference. Moreover, since the bandwidth of each sub-channel is only a small fraction of the original channel bandwidth, channel equalization becomes relatively easy.

[0157] 2. Component carrier (CC): A carrier refers to a radio wave of a specific frequency band that is modulated to transmit a signal, or an electromagnetic wave of a certain bandwidth.

[0158] 3. Subcarrier: In the OFDM system, a subcarrier is obtained by dividing a carrier of a certain bandwidth.

[0159] 4. Subcarrier spacing (SCS): SCS is the width of a subcarrier, usually 15kHz or multiples of 15kHz, where kHz stands for kilohertz.

[0160] 5. Symbol length: refers to the length of the OFDM symbol. The symbol length is usually the reciprocal of the subcarrier spacing. For example, the symbol length corresponding to a 15kHz SCS is 66.7 microseconds (μs).

[0161] 6. Cyclic prefix (CP): CP is formed by copying the signal at the end of the OFDM symbol to the beginning. There are two main types of CPs: normal CP and extended CP. The normal CP is 4.7μs long, and the extended CP is 16.67μs long. The cyclic prefix can be associated with other multipath component information to obtain complete information. In addition, the cyclic prefix can achieve time estimation and frequency synchronization. In the physical random access channel (PRACH), there is also a PRACH CP, and the length of the PRACH CP is usually longer than that of the normal CP.

[0162] 7. Receive window (Rx window): This refers to the configured length of time for receiving return signals. Return signals refer to multipath signals such as reflected signals and diffracted signals corresponding to the transmitted perception signals.

[0163] 8. Frequency band: Frequency band refers to a frequency domain resource of a certain width, which can be a carrier or a bandwidth part (BWP).

[0164] 9. Beam: A beam is a communication resource. A beam can be a wide beam, a narrow beam, or other types of beams. The technology used to form the beam can be beamforming technology or other technical means. Beamforming technology can specifically include digital beamforming technology, analog beamforming technology, and hybrid digital / analog beamforming technology. Different beams can be considered as different resources. The beam used to send signals can be called a transmission beam (Tx beam), and the beam used to receive signals can be called a reception beam (Rx beam). The transmission beam can refer to the distribution of signal strength in different directions in space after the signal is transmitted by the antenna, and the reception beam can refer to the signal strength distribution of the wireless signal received from the antenna in different directions in space.

[0165] 10. Aggregated bandwidth: This refers to a larger transmission resource composed of component bandwidths on at least two carriers. Aggregated bandwidth is essentially a frequency domain resource with a large frequency range. The component bandwidth can be part or all of the bandwidth on a carrier, that is, part or all of the frequency domain resources on a carrier.

[0166] The method for determining aggregate bandwidth provided in the embodiments of the present application can be implemented through the interaction of a first device and a second device, wherein the first device can be a communications device or a communications device capable of supporting the communications device in implementing the functions required by the method for determining aggregate bandwidth, such as a chip. Exemplarily, the first device is a terminal device / network device (e.g., a base station), or a chip disposed in the terminal device / network device for implementing the functions of the terminal device / network device, or other components for implementing the functions of the terminal device / network device. In the following description, the first device is described as an example of a terminal device. It should be noted that the first device can also be a network device or a dedicated sensing device. The second device can be a communications device or a communications device capable of supporting the communications device in implementing the functions required by the method for determining aggregate bandwidth, such as a chip. Exemplarily, the second device is a network device / terminal device, or a chip disposed in the network device / terminal device for implementing the functions of the network device / terminal device, or other components for implementing the functions of the network device / terminal device. In the following description, the second device is described as an example of a network device. It should be noted that the second device can also be a dedicated sensing device. When the second device is a network device, it can be a device in the core network or an access network device. The method for determining the aggregated bandwidth of the present application is described below with reference to the accompanying drawings.

[0167] As shown in FIG2 , the method for determining the aggregate bandwidth provided in an embodiment of the present application includes:

[0168] S201: The second device sends first information. Correspondingly, the first device receives the first information.

[0169] The first information includes information about a sensing performance requirement and at least one aggregated bandwidth, where each aggregated bandwidth of the at least one aggregated bandwidth is used to transmit a sensing reference signal or channel.

[0170] In this application, the sensing performance requirements refer to the requirements for transmitting SERS.

[0171] S202. The first device determines second information based on the first information.

[0172] The second information includes information about the first aggregate bandwidth, where the first aggregate bandwidth is an aggregate bandwidth that meets the perceived performance requirement among the at least one aggregate bandwidth.

[0173] In this application, there may be one or more first aggregate bandwidths. If at least one aggregate bandwidth in the first information does not include a first aggregate bandwidth that meets the perceived performance requirement, the first device may provide feedback indicating that no aggregate bandwidth meets the perceived performance requirement. The second device may then send information about other aggregate bandwidths until the first device determines that a first aggregate bandwidth that meets the perceived performance requirement is found.

[0174] S203: The first device sends the second information to the second device. Correspondingly, the second device receives the second information.

[0175] In the solution provided by the embodiments of the present application, a first device can screen at least one aggregate bandwidth based on the perception performance requirement and information about at least one aggregate bandwidth sent by a second device, select a first aggregate bandwidth that meets the perception performance requirement, and report the information about the first aggregate bandwidth that meets the perception performance requirement to the second device. In this way, when the second device subsequently configures an aggregate bandwidth for the first device to transmit a perception reference signal or channel, it can configure the first aggregate bandwidth that meets the perception performance requirement, thereby improving resource utilization of the communication system. Furthermore, when the first aggregate bandwidth is used for subsequent SERS transmission, it can improve perception accuracy and / or perception resolution.

[0176] Optionally, the above-mentioned step S202 of determining the second information based on the first information can be implemented through multiple possible implementation methods, such as: determining the second information through the capability information of the first device, determining the second information through a self-perception process, or determining the second information through a sending and receiving separation process, which are introduced below respectively.

[0177] 1. The first device determines the second information based on the capability information;

[0178] This process can be understood by referring to FIG3 . As shown in FIG3 , the solution for determining the aggregate bandwidth based on capability information may include the following steps:

[0179] S301. A first device receives a sensing capability request from a second device and sends a sensing capability response to the second device. Correspondingly, the second device receives the sensing capability response.

[0180] The second device shown in Figure 3 can be an access network device that includes SEF or is in communication with SEF, a device in the core network (such as access and mobility management function (AMF)), or an independent SEF module or SEF device.

[0181] The first device feeds back the perception capability of the first device to the second device through a perception capability response, such as one or more of: duplex capability, multi-carrier capability, bandwidth capability, self-perception capability (such as: round trip time (RTT) of the perception signal), whether aggregated bandwidth is supported or whether the gap (GAP) of the bandwidth components in the aggregated bandwidth can be flexibly configured, etc.

[0182] The second device can determine whether the first device has the ability to judge the aggregate bandwidth and whether it meets the perception performance requirements through the perception capability feedback from the first device. If the first device has the ability to judge the aggregate bandwidth and meet the perception performance requirements, the second device sends the first information to the first device.

[0183] S302: The second device sends the first information. Correspondingly, the first device receives the first information.

[0184] The first information includes information of a perceived performance requirement and at least one aggregate bandwidth.

[0185] S303. The first device determines, based on the capability information, a first aggregate bandwidth that meets the perceived performance requirement from at least one aggregate bandwidth.

[0186] The perception performance requirements for this situation may include: a first expected value and a first deviation range of distance resolution; or, a second expected value and a second deviation range of distance accuracy; wherein the first deviation range is a range of deviation between the distance resolution determined according to the capability of the first device and the first expected value, the second deviation range is a range of deviation between the distance accuracy determined according to the capability of the first device and the second expected value, and the second expected value is an expected value under the signal-to-noise ratio configured by the second device.

[0187] The first device may determine the actual value of the distance resolution of each aggregated bandwidth in at least one aggregated bandwidth based on the capabilities of the first device, and determine whether the actual value of the distance resolution is within a first deviation range by comparing the actual value with the first expected value. If the actual value is within the first deviation range, the corresponding aggregated bandwidth may be determined to be the first aggregated bandwidth that meets the perception performance requirement. And / or,

[0188] The first device determines the actual value of the distance accuracy of each aggregate bandwidth in at least one aggregate bandwidth based on the capability of the first device, and determines whether the actual value of the distance accuracy is within a second deviation range by comparing the second expected value. If they are within the second deviation range, the corresponding aggregate bandwidth can be determined to be the first aggregate bandwidth that meets the perception performance requirements.

[0189] The first expected value of the distance resolution can also be understood as a theoretical value. The theoretical value of the distance resolution can be obtained by Determine, where ΔR is the range resolution, c = 3*1e8 m / s is the speed of light, and B is the bandwidth of the aggregated bandwidth. The actual value of the range accuracy may be determined by the capabilities of the first device and may also be affected by other factors, such as the OFDM symbol or chirp symbol length, phase continuity between the components of the aggregated bandwidth, transmission time alignment, and differences in the hardware corresponding to the component bandwidths (e.g., antennas, RF channels).

[0190] The second expected value of the distance accuracy under a given signal-to-noise ratio (SNR) can also be understood as a theoretical value. The theoretical value of the distance accuracy can be obtained by Determine, where σ R is the distance accuracy, and SNR is the given signal-to-noise ratio. The actual value of the distance accuracy may be determined by the capabilities of the first device and may also be affected by other factors, such as the symbol length of the OFDM symbol or chirp, whether the phases of the components of the aggregated bandwidth are continuous, whether the transmission time is aligned, and whether the hardware corresponding to the component bandwidths (e.g., antennas, RF channels) are different.

[0191] The bandwidth value B of the above-mentioned aggregate bandwidth can be determined from the information of at least one aggregate bandwidth. The information about at least one aggregate bandwidth is explained by taking one of them as an example. This one aggregate bandwidth can be called the second aggregate bandwidth. The information of the second aggregate bandwidth includes two items of the frequency starting position, frequency ending position or bandwidth value of the first component bandwidth, and two items of the frequency starting position, frequency ending position or bandwidth value of the second component bandwidth. The first component bandwidth is located on the first carrier, and the second component bandwidth is located on the second carrier. The second aggregate bandwidth is any one of the at least one aggregate bandwidth.

[0192] The bandwidth value B of the aggregate bandwidth can be obtained by summing the bandwidth value of the first component bandwidth and the bandwidth value of the second component bandwidth. Of course, if the second aggregate bandwidth includes more component bandwidths, the bandwidth values ​​of all component bandwidths can be summed to obtain B. Of course, if the second aggregate bandwidth information does not directly provide the bandwidth values ​​of the component bandwidths but provides the frequency start and end positions of the component bandwidths, the bandwidth value of the component bandwidth can be calculated based on the frequency start and end positions.

[0193] S304: The first device sends the second information to the second device. Correspondingly, the second device receives the second information.

[0194] The second information may include information about the first aggregate bandwidth that meets the perceived performance requirement. It should be noted that the second information may also include the maximum GAP among the component bandwidths of the aggregate bandwidth.

[0195] In the embodiment of the present application, because the second device can flexibly configure two of the frequency start position, frequency end position, or bandwidth value of each component bandwidth when configuring at least one aggregate bandwidth, the gap (GAP) between each two component bandwidths can be flexible. A flexible GAP can improve the flexibility of the aggregate bandwidth.

[0196] For more information on the flexible GAP between the component bandwidths of an aggregated bandwidth, refer to Figure 4. As shown in Figure 4, taking the example of an aggregated bandwidth comprising a first component bandwidth on a first carrier (CC1) and a second component bandwidth on a second carrier (CC2), the GAP between the first component bandwidth and the second component bandwidth is the distance from the frequency end position of the first component bandwidth to the frequency start position of the second component bandwidth.

[0197] In 401 of FIG4 , the frequency end position of the first component bandwidth is at the end position of the frequency of the first carrier, and the frequency start position of the second component bandwidth is at the start position of the frequency of the second carrier. Therefore, the GAP between the first component bandwidth and the second component bandwidth in 401 is equal to the guard period (GP) between the first carrier and the second carrier.

[0198] In 402 of FIG4 , the frequency end position of the first component bandwidth is at the frequency end position of the first carrier, and the frequency start position of the second component bandwidth is at or near the middle position of the second carrier, so the GAP between the first component bandwidth and the second component bandwidth in 402 is larger.

[0199] In FIG4 , in step 403 , the frequency end position of the first component bandwidth is at or near the middle of the first carrier, and the frequency start position of the second component bandwidth is at the start position of the second carrier. Therefore, the gap between the first component bandwidth and the second component bandwidth in step 403 is also large.

[0200] In FIG4 , at 404 , the frequency of the first component bandwidth ends at or near the end of the first carrier, and the frequency of the second component bandwidth begins at or near the middle of the second carrier. Therefore, the gap between the first component bandwidth and the second component bandwidth in 404 is also large.

[0201] From the comparison between 401 and 404 in FIG4 , it can be seen that the frequency start position, frequency end position or bandwidth value of the component bandwidths of the aggregated bandwidth can be flexibly configured, and the GAP between the component bandwidths of the aggregated bandwidth is also flexible.

[0202] The GAP between the first component bandwidth and the second component bandwidth can be calculated based on the bandwidth value, frequency start position or frequency end position of the above-mentioned component bandwidth. For example, the GAP between the first component bandwidth and the second component bandwidth can be: the difference between the distance between the frequency start position of the first component bandwidth and the frequency end position of the second component bandwidth and the bandwidth value of the first component bandwidth and the bandwidth value of the second component bandwidth; or, the difference between the distance between the frequency start position of the first component bandwidth and the frequency start position of the second component bandwidth and the bandwidth value of the first component bandwidth; or, the difference between the distance between the frequency end position of the first component bandwidth and the frequency end position of the second component bandwidth and the bandwidth value of the second component bandwidth; or, the difference between the frequency end position of the first component bandwidth and the frequency start position of the second component bandwidth.

[0203] The information of at least one aggregate bandwidth in the first information may be configured in the form of the following Table 1, as shown in Table 1:

[0204] Table 1: Information about at least one aggregated bandwidth

[0205] In Table 1, the aggregate bandwidth index is used to identify different aggregate bandwidths, the carrier index is used to indicate which carriers the component bandwidths on which different aggregate bandwidths are composed, and the information is used to indicate the bandwidth values ​​and starting positions of the component bandwidths on different carriers. The component bandwidths of aggregate bandwidth 0 are located on carriers 0 and 1, with a bandwidth value of BW1 on carrier 0 and a frequency starting position of 01, and a bandwidth value of BW2 on carrier 1 and a frequency starting position of 02. The component bandwidths of aggregate bandwidth 1 are located on carriers 0 and 1, with a bandwidth value of BW1 on carrier 0 and a frequency starting position of 11, and a bandwidth value of BW3 on carrier 1 and a frequency starting position of 12. The component bandwidths of aggregate bandwidth 2 are located on carriers 1 and 2, with a bandwidth value of BW4 on carrier 1 and a frequency starting position of 21, and a bandwidth value of BW4 on carrier 2 and a frequency starting position of 22.

[0206] It should be noted that the information in Table 1 is described using the bandwidth value and frequency starting position of the bandwidth as an example. In fact, the information can also be the frequency ending position and the bandwidth value of the bandwidth, or the frequency starting position and frequency ending position.

[0207] In this embodiment of the present application, the gap between the first component bandwidth and the second component bandwidth may also be represented by puncture resource information. For example, the information about the second aggregate bandwidth may also include puncture resource information. The puncture resource information is used to indicate that the puncture resources in the first carrier and / or the second carrier are not used for transmitting the perception reference signal. The puncture resources can then be used for other data transmission, thereby improving carrier resource utilization.

[0208] For more information about puncturing resources, refer to Figure 5. As shown in Figure 5, the puncturing resources in the second aggregate bandwidth information are distributed across the first and second carriers. There is a puncturing resource 501 near the end of the first carrier's frequency range, and a puncturing resource 502 near the beginning of the second carrier's frequency range. Puncturing resources 501 and 502 can be used to transmit data other than SERS or remain unused.

[0209] When the information of the second aggregate bandwidth includes information of puncturing resources, the width of the puncturing resources and the protection interval between the first carrier and the second carrier is the gap GAP between the first component bandwidth and the second component bandwidth. As shown in Figure 5, the GAP can be the width of 501+502+GP. The puncturing resources 501 and the puncturing resources 502 shown in Figure 5 have the same width. In fact, the puncturing resources can be distributed at different positions on the first carrier or the second carrier, and the widths can be the same or different. There can also be puncturing resources on only one carrier and no puncturing resources on the other carrier. Because the puncturing resources are not fixed, the puncturing resources and GP together constitute the GAP between the component bandwidths of the aggregate bandwidth, which can improve the flexibility of the GAP. Flexible GAP configuration can support flexible aggregate bandwidth configuration, which is beneficial for the communication system to support various types of services for resource multiplexing.

[0210] In an embodiment of the present application, the information of the second aggregate bandwidth also includes a pattern for transmitting a perception reference signal in the component bandwidth, and at least two component bandwidths of the second aggregate bandwidth correspond to at least one pattern. Wherein, the pattern of the reference signal refers to the frequency domain and / or time domain position distribution of the reference signal on the bandwidth where it is located, such as the distribution of adjacent reference signal resource elements at fixed intervals on the bandwidth where the reference signal is located starting from the starting resource of the bandwidth where it is located. In other words, the SERS patterns in different component bandwidths of the second aggregate bandwidth can be the same or different. As shown in Figure 5, the SERS patterns on the first component bandwidth and the second component bandwidth are the same. As shown in Figure 6, the SERS patterns on the first component bandwidth and the second component bandwidth are different. In this way, a flexible SERS pattern configuration can improve the flexibility of SERS transmission in the aggregate bandwidth.

[0211] In this embodiment of the present application, the first information also includes feedback on the maximum number of first aggregate bandwidths, for example, M. If the number N of first aggregate bandwidths that meet the perceived performance requirements determined by the first device is greater than the maximum number M in the first information, only information on M first aggregate bandwidths may be fed back, where both M and N are positive integers. This not only meets the needs of the second device and configures a reasonable aggregate bandwidth, but also reduces the length of the second information, saving resources for transmitting the second information.

[0212] Optionally, the above-mentioned perceptual performance requirements may also include a first value and / or a second value, the first value being used to indicate a value that the distance resolution determined by the first device under the signal-to-noise ratio indicated by the second device must satisfy, and the second value being used to indicate a value that the distance accuracy determined by the first device under the signal-to-noise ratio indicated by the second device must satisfy.

[0213] When the perceived performance requirement includes the first value and / or the second value, the second information further includes a maximum gap GAP value between component bandwidths of the first aggregate bandwidth. The granularity of the maximum GAP value can be a resource element (RE), a resource block (RB), a resource block group (RBG), a bandwidth part (BWP), or a carrier bandwidth.

[0214] The feedback form of the maximum GAP in the second information can be understood by referring to Table 2, as shown in Table 2:

[0215] Table 2: Maximum GAP feedback form

[0216] In Table 2, when aggregate bandwidth 0 meets perception performance requirement A, the maximum GAP value of the bandwidths composed of the four carriers 0, 1, 2, and 3 can be X, where the GAP value is, for example, the number of resource blocks. When aggregate bandwidth 1 meets perception performance requirement B, the maximum GAP value of the bandwidths composed of the four carriers 0, 1, 2, and 3 can be Y. When aggregate bandwidth 2 meets perception performance requirement C, the maximum GAP value of the bandwidths composed of the four carriers 0, 1, 2, and 3 can be Z. A, B, or C can be the first value (i.e., the value that the range resolution must meet at a given signal-to-noise ratio) and / or the second value (i.e., the value that the range accuracy must meet at a given signal-to-noise ratio) described above.

[0217] The first device may include the maximum gap value between component bandwidths of the first aggregate bandwidth in the second information. This allows the second device to select appropriate component bandwidths within the maximum gap value range to form an aggregate bandwidth that meets the perceived performance requirements, thereby increasing the second device's flexibility in configuring the aggregate bandwidth that meets the perceived performance requirements.

[0218] Second, determine the second information through the process of self-perception;

[0219] This process can be understood with reference to FIG. 7A . As shown in FIG. 7A , the solution for determining the aggregate bandwidth through the self-sensing process may include the following steps:

[0220] S701. A first device receives a sensing capability request from a second device and sends a sensing capability response to the second device. Correspondingly, the second device receives the sensing capability response.

[0221] The second device shown in Figure 7A can be an access network device that includes SEF or is in communication with SEF, a device in the core network (such as access and mobility management function (AMF)), or an independent perception function SEF device or SEF device.

[0222] The first device feeds back the sensing capability of the first device to the second device through a sensing capability response, such as one or more of half-duplex capability, full-duplex capability, maximum bandwidth of a supported carrier, etc.

[0223] The second device can determine whether the first device has the ability to judge the aggregate bandwidth and whether it meets the perception performance requirements through the perception capability feedback from the first device. If the first device has the ability to judge the aggregate bandwidth and meet the perception performance requirements, the second device sends the first information to the first device.

[0224] S702. The SEF sends a resource configuration request for the aggregated bandwidth to the access network device. Correspondingly, the access network device receives the resource configuration request for the aggregated bandwidth.

[0225] The SEF may send a transmission characteristic requirement to the access network device and obtain resource configuration of the aggregated bandwidth from the access network device. The resource configuration request sent by the SEF corresponds to the transmission characteristic requirement.

[0226] S703. The access network device sends a resource configuration response of the aggregated bandwidth to the SEF. Correspondingly, the SEF receives the resource configuration response of the aggregated bandwidth.

[0227] S704. The SEF sends the first information to the first device. Correspondingly, the first device receives the first information.

[0228] The first information includes information of a perceived performance requirement and at least one aggregate bandwidth.

[0229] The information of at least one aggregated bandwidth includes information of a first target, resource information of a first perception reference signal, measurement information, and feedback information; wherein the first target is used to reflect the first perception reference signal.

[0230] The resource information of the first perception reference signal includes at least one of information about a waveform of the first perception reference signal, information about a resource for transmitting the first perception reference signal, beam information, and transmit power information of the first perception reference signal.

[0231] The waveform information may include one or more of the SCS and CP of OFDM, the SCS of the chirp of frequency modulated continuous waveform (FMCW), the time domain or bandwidth of the chirp, and the like.

[0232] Information about the resources used to transmit the first sensing reference signal can be understood by referring to the bandwidth value, frequency start position, frequency end position, SERS pattern, and other related information in the embodiment section corresponding to FIG3 . Information about the aggregate bandwidth of the self-sensing process can also include the start time and duration (or end time) of the receiving window. The first device is used to monitor the second sensing reference signal. The second sensing reference signal can include a reflected signal, which can be a signal reflected by the first target after the first sensing reference signal encounters the first target. The reflected signal can also be an echo signal.

[0233] The beam information may include: a transmit beam indication and / or receive beam indication of the SERS, such as configuring the transmit (Tx) and / or receive (Rx) direction of one or more self-sensing beams for the self-sensing first device, which may be configured in the form of a transmit / receive beam resource set or a SERS resource set, and may be used to transmit a first sensing reference signal (transmit beam signal) to a first target (reference target) and receive a second sensing reference signal (reflected beam signal). The SERS / sounding reference signal (SRS) / synchronization signal / broadcast channel block (SSB) direction of the current cell or neighboring cell may also be configured as the self-sensing beam direction, or the offset direction of the related reference signal (RS) direction may be configured as the transmit and / or receive direction of the self-sensing beam. If the capability of the first device supports reciprocity of transmit and receive beams, only the direction of the transmit or receive beam may be configured. If the capability of the first device does not support reciprocity of transmit and receive beams, the directions of the transmit and receive beams may be configured.

[0234] The transmit power information of the first perception reference signal is used to determine the transmit power to the reference target. In the embodiment of the present application, the reference path loss (PL reference ) and its coefficient alpha, the expected received power P target , maximum transmit power P CMAX Determine the transmission power of SERS. For example, Tx power = Min{P CMAX , P target +alpha*PL reference}. Among them, P target and alpha by configuring nodes such as network configuration, while PL reference, which is obtained by configuring the reference signal. The first device can obtain the transmit power of the reference signal and obtain the path loss value by measuring the received power. The reference path loss can be obtained based on the SERS / SSB / channel state information reference signal (CSIRS) or positioning reference signal (PRS) or demodulation reference signal (DMRS) or phase tracking reference signal (PTRS) of the current cell or neighboring cell.

[0235] The measurement information includes at least one of the RTT information from when the first perception reference signal is sent to when the corresponding second perception reference signal is received, the angle at which the first perception reference signal is sent (i.e., the sending angle, also known as the angle of departure (AoD)), the angle at which the second perception reference signal is received, the received power of the second perception reference signal, and the signal-to-noise ratio of the second perception reference signal.

[0236] The feedback information includes a resource for feeding back the second information.

[0237] The perceptual performance requirement includes at least one of a range of RTT measurement values, a range of received power of the second perceptual reference signal, or a range of angles at which the second perceptual reference signal is received (i.e., a reception angle or angle of arrival (AoA)). The perceptual performance requirement may also include a range of Doppler shift values.

[0239] S706. The first device receives a second perception reference signal.

[0240] S707. The first device measures the second perception reference signal to determine second information.

[0241] The first device determines, based on measurement of the second perception reference signal, an actual value of a reception angle of the second perception reference signal, an actual value of a received power of the second perception reference signal, and an actual value of an RTT from sending the first perception reference signal to receiving the second perception reference signal, and determines whether these actual values ​​fall within a range of a perception performance requirement, thereby determining whether the corresponding aggregate bandwidth meets the perception performance requirement.

[0242] S708: The first device sends the second information to the access network device, and the access network device then sends the second information to the SEF.

[0243] When reporting the first aggregate bandwidth information, the first device may also report the first aggregate bandwidth index and the perception measurement result; or the first aggregate bandwidth index and the perception measurement time. This allows the second device to obtain more accurate measurement information about the first aggregate bandwidth.

[0244] In the above-described solution for determining the aggregate bandwidth through the self-sensing process, the first information is sent by the SEF on the core network side. If the first information is sent by the access network device, the process can be understood with reference to FIG. 7B . As shown in FIG. 7B , the process includes:

[0261] The resource information of the third perception reference signal includes at least one of waveform information of the third perception reference signal, information about resources for transmitting the third perception reference signal, beam information, and transmit power information of the third perception reference signal. For more information on this topic, please refer to the relevant information on resource information in the self-sensing solution.

[0262] The measurement information of the third perceptual reference signal includes at least one of an angle at which the third perceptual reference signal is received, a received power of the third perceptual reference signal, and a signal-to-noise ratio of the third perceptual reference signal.

[0263] The feedback information of the third perception reference signal includes a resource for feeding back the second information.

[0264] The perceptual performance requirement includes at least one of a range of a time difference between a transmission time and a reception time of a perceptual reference signal indicated by the second device to the first device, a range of a received power of a third perceptual reference signal, and a range of an angle at which the third perceptual reference signal is received.

[0265] In one possible implementation, the second device provides the first device with resource information, measurement information, feedback information for transmission and reception separation, and perception performance requirements through the first information, so that the first device can more effectively measure the third SERS sent by the second device and more accurately determine the first aggregate bandwidth that meets the perception performance requirements.

[0266] S805. The first device receives a third perception reference signal sent by the access network device.

[0267] S806. The first device measures the third perception reference signal to determine second information.

[0268] The first device determines, based on the measurement of the third perception reference signal, the actual value of the receiving angle of the third perception reference signal and the actual value of the receiving power of the third perception reference signal, and determines whether these actual values ​​fall within the range of the perception performance requirements, thereby determining whether the corresponding aggregated bandwidth meets the perception performance requirements.

[0269] S807: The first device sends the second information to the access network device, and the access network device then sends the second information to the SEF.

[0270] When reporting the first aggregate bandwidth information, including information about the first aggregate bandwidth, the first device may also report the first aggregate bandwidth index and perception measurement results; or the first aggregate bandwidth index and perception measurement time; or the index, perception measurement results, and perception measurement time.

This allows the second device to obtain more accurate measurement information about the first aggregate bandwidth.

[0271] In the above-described solution for determining the aggregate bandwidth through the self-sensing process, the first information is sent by the SEF on the core network side. If the first information is sent by the access network device, the process can be understood with reference to FIG8B . As shown in FIG8B , the process includes:

[0280] In the embodiments of Figures 7A, 7B, 8A, and 8B, when the first information also includes information about the available aggregate bandwidth for the second target, the available aggregate bandwidth may also be used to perform perception measurements on the second target. The available aggregate bandwidth may not specify a specific aggregate bandwidth, but may instead indicate that an aggregate bandwidth that meets the perception performance requirements should be selected from at least one aggregate bandwidth in the first information sent by the second device for the perception measurement of the second target. For example, after determining the second information, the first device may select a first aggregate bandwidth to perform perception measurements on the second target. Alternatively, the first device may directly select an aggregate bandwidth that meets the perception performance requirements for the second target based on the transmission resources of the aggregate bandwidths configured by the second device in the first information. Regardless of the method used to select the available aggregate bandwidth, after completing the perception measurement of the second target, the results of the perception measurement of the second target using the aggregate bandwidth may be reported, along with information about the aggregate bandwidth used and / or other aggregate bandwidths that meet the perception performance requirements.

[0281] The second target may be an unknown target, so the second device does not need to wait for the first aggregate bandwidth information fed back by the first device before instructing the first device to perform measurement, thereby reducing the measurement delay of the second target.

[0282] Having described the communication system and the method for determining aggregate bandwidth in the embodiments of the present application, the following describes the communication device provided in the embodiments of the present application. Please refer to Figure 9, which is a schematic diagram of the structure of the communication device in the embodiments of the present application. Communication device 900 can be used to perform the steps in the embodiments shown in Figures 2 to 8B. For details, please refer to the relevant descriptions in the above method embodiments.

[0283] The communication device 900 includes a transceiver module 901 and a processing module 902. The transceiver module 901 can implement corresponding communication functions, and the processing module 902 is used to process data.

[0287] It should be noted that the communication device 900 may include a sending module but not a receiving module. Alternatively, the communication device 900 may include a receiving module but not a sending module. The specific implementation depends on whether the above solution executed by the communication device 900 includes a sending action and a receiving action.

[0289] The transceiver module 901 is configured to receive first information.

[0290] The processing module 902 is configured to determine second information based on the first information.

[0291] It should be understood that the specific process of each module executing the above corresponding steps has been described in detail in the above method embodiment, and for the sake of brevity, it will not be repeated here.

[0292] The processing module 902 in the above embodiment can be implemented by at least one processor or processor-related circuits. The transceiver module 901 can be implemented by a transceiver or transceiver-related circuits. The transceiver module 901 can also be referred to as a communication unit or communication interface. The storage unit can be implemented by at least one memory.

[0293] The present application also provides another communication device 1000. As shown in FIG10 , the communication device 1000 includes a processor 1010, which is coupled to a memory 1020. The memory 1020 is configured to store computer programs, instructions, and / or data. The processor 1010 is configured to execute the computer programs, instructions, and / or data stored in the memory 1020, thereby executing the method in the above method embodiment.

[0294] Optionally, the communication device 1000 includes one or more processors 1010.

[0295] Optionally, as shown in FIG10 , the communication device 1000 may further include a memory 1020 .

[0296] Optionally, the communication device 1000 may include one or more memories 1020 .

[0297] Optionally, the memory 1020 may be integrated with the processor 1010 or provided separately.

[0298] 10 , the communication device 1000 may further include a transceiver 1030 , which is configured to receive and / or transmit signals. For example, the processor 1010 is configured to control the transceiver 1030 to receive and / or transmit signals.

[0299] As a solution, the communication device 1000 is used to implement the operations in the above method embodiments.

[0300] For example, the processor 1010 is used to implement processing-related operations in the above method embodiments, and the transceiver 1030 is used to implement transmission-related operations in the above method embodiments.

[0301] The present application also provides a communication device 1000, which can be a terminal device, access network device, core network device, SEF device, or SEF module, or a chip or module in the terminal device, access network device, core network device, SEF device, or SEF module. The communication device 1000 can be used to perform the operations in the above method embodiments.

[0302] When the communication device 1000 is a communication device, Figure 11 shows a simplified structural diagram of the communication device. As shown in Figure 11, the communication device includes a processor, a memory, and a transceiver, wherein the memory can store computer program code, and the transceiver includes a transmitter 1031, a receiver 1032, a radio frequency circuit (not shown in the figure), an antenna 1033, and an input / output device (not shown in the figure). The processor is mainly used to process communication protocols and communication data, as well as to control the communication device, execute software programs, process software program data, etc. The memory is mainly used to store software programs and data. The radio frequency circuit is mainly used to convert baseband signals into radio frequency signals and process radio frequency signals. The antenna is mainly used to transmit and receive radio frequency signals in the form of electromagnetic waves. Input / output devices, such as a touch screen, a display screen, a keyboard, etc., are mainly used to receive data input by the user and output data to the user. It should be noted that some types of communication devices may not have input / output devices.

[0303] When data needs to be sent, the processor performs baseband processing on the data to be sent, and then outputs the baseband signal to the RF circuit. The RF circuit performs RF processing on the baseband signal and then sends the RF signal outward in the form of electromagnetic waves through the antenna.
