Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a communication method and device. Background Art

[0002] During the perception process, when the core network equipment instructs the base station to perform the perception task, it will send the perception requirements corresponding to the perception task to the access network equipment, such as the perception location accuracy requirement, rate accuracy requirement, perception allocation rate requirement, etc.; after receiving the perception requirements from the core network, the access network equipment will configure the corresponding perception wireless resources according to the perception requirements, such as time domain resources, frequency domain resources, spatial domain resources, etc., and perform the perception task based on the perception wireless resources to obtain the perception results.

[0003] However, the sensing results obtained by the access network equipment based on sensing wireless resources may not meet the requirements of the sensing task, or the requirements of the sensing task may change. In this case, how to perform the sensing task and improve the sensing performance is an urgent problem to be solved. Summary of the invention

[0004] The embodiments of the present application provide a communication method and device, which can improve perception performance.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] In a first aspect, a communication method is provided, which can be executed by an access network device, or by a component of the access network device, such as a processor, chip, or chip system of the access network device, or can be implemented by a logic module or software that can implement all or part of the functions of the access network device, such as a distributed unit (DU). The following is an illustration of the method being executed by an access network device. The method includes: sending a first message, the first message carrying a first perception measurement result, the first perception measurement result being a result obtained by measuring in a perception task based on a first perception requirement; receiving a second message, and performing a perception task based on a second perception requirement, the second message carrying information for indicating a second perception requirement, the second perception requirement being used for the perception task, and the second perception requirement being different from the first perception requirement.

[0007] Based on the method from the first aspect to the second aspect, it can be known that the access network device currently performs the perception task based on a set of perception wireless resources, that is, the perception wireless resources will not change during the process of the access network device performing the perception task. However, in the perception task, there may be multiple different perception states. For example, the perception task needs to perform perception measurement on the objects in the surrounding environment at the beginning, and after measuring the object, the target object in the object is continuously located. In this case, using a set of perception wireless resources for perception measurement cannot cope with different perception states in the perception process, so that the perception results obtained based on the perception wireless resources cannot meet the requirements of the perception task. Therefore, the access network device can use multiple sets of wireless perception resources to perform the perception task to cope with different perception states in the perception process. For example, in the process of performing the perception task, the access network device can report the first perception measurement result measured based on the first perception requirement, so that the first network element can adjust the subsequent perception requirement (i.e., the second perception requirement) according to the first perception measurement result, and send the second perception requirement to the access network device; after receiving the second perception requirement, the access network device can configure the wireless perception resource corresponding to the second perception requirement, and continue to perform perception measurement based on the wireless perception resource. In this way, the access network device can configure different perception wireless resources according to different perception requirements sent by the first network element, so that the results of measurements based on different perception wireless resources during the perception process can meet the requirements of the perception task and improve the perception performance.

[0008] In a possible design scheme, the second message carries first indication information, and the first indication information is used to indicate a second beam that performs a perception task based on a second perception requirement. It can be understood that when the access network device is required to use an omnidirectional beam for perception measurement, the perception requirement, such as the first perception requirement, the second perception requirement, etc., can be indicated to the access network device. At this time, the access network device can use the perception wireless resources configured according to the perception requirement to perform perception measurements in all directions; when the access network device is required to use a directional beam, the perception requirement and the beam corresponding to the perception requirement can be indicated to the access network device, so that the access network device configures the perception wireless resources according to the perception requirement and performs the perception task on the beam using the perception wireless resources. In this way, when the access network device is required to use a directional beam, the access network device can perform perception measurements based on the second beam, thereby ensuring the smooth progress of the perception measurement.

[0009] Optionally, the first indication information is location information or direction information. It can be understood that the first perceived object can be determined based on the first perception measurement result, and the first indication information can be the location information or direction information of the second perceived object determined based on the first perceived object, and the perceived objects in the second perceived object are at least part of the perceived objects in the first perceived object, that is, the access network device needs to perform perception measurement on the second perceived object according to the second perception requirement. In this way, the access network device can accurately determine the second beam based on the location information or direction information of the second perceived object.

[0010] Further, the direction information is a departure angle direction or a transmission direction. That is, the direction information may be a departure angle direction or a transmission direction of the second beam. The direction information may be determined according to the positions of the second sensed object and the access network device.

[0011] Optionally, the first message also carries beam information of the first beam corresponding to the first perception measurement result, and the second beam belongs to the first beam. It can be understood that under non-line-of-sight conditions, the access network device can send both the first perception measurement result and the first beam to the first network element, so that the first network element can determine on which beam different perceived objects in the first perception measurement result are measured. After the first network element determines the second perceived object from the first perceived object corresponding to the first perception measurement result, it can send the second perception requirement determined based on the second perceived object together with the second beam to the access network device, so that the access network device can perform the perception task on the second beam using the perception wireless resources corresponding to the second perception requirement, thereby ensuring the correctness of the beam used to utilize the perception wireless resources.

[0012] Furthermore, the beam information is the beam number and / or the transmission direction of the beam. That is, different beams can be accurately indicated by the beam number and / or the transmission direction of the beam.

[0013] In a possible design, the second message also carries first time information, and the first time information is used to indicate the time of sending the second perception measurement result, and the second perception measurement result is a result obtained by measuring based on the second perception requirement in the perception task. In this way, the first network element can flexibly set the time for the access network device to report the second perception measurement result according to actual conditions.

[0014] In a possible design, before sending the first message, the method described in the first aspect further includes: receiving a third message, and configuring the perceptual wireless resources corresponding to the first perceptual requirement according to the third message; wherein the third message carries information for indicating the first perceptual requirement. That is, the first network element can indicate the perceptual requirement to be used to the access network device, without the need for the access network device to preconfigure a plurality of different perceptual requirements, that is, without the need to select the perceptual requirement to be used from the preconfigured plurality of different perceptual requirements, thereby improving the flexibility of perceptual wireless resource configuration.

[0015] In a possible design, before sending the first message, the method described in the first aspect further includes: receiving a third message, and configuring a plurality of perception radio resources corresponding to different perception requirements according to the third message; wherein the third message carries information indicating a plurality of different perception requirements, and the plurality of different perception requirements include a first perception requirement and a second perception requirement. In this way, it is convenient for the access network device to switch perception radio resources corresponding to different perception requirements during the execution of the perception task.

[0016] Optionally, the third message also carries second time information, and the second time information is used to indicate the time of sending the first perception measurement result, where the first perception measurement result is a result obtained by measuring based on the first perception requirement in the perception task. In this way, the first network element can flexibly set the time for the access network device to report the first perception measurement result according to actual conditions.

[0017] Optionally, the fifth message carries information for indicating the first perception requirement. It can be understood that the fifth message can be used to indicate the initiation of perception measurement for the perception task. That is to say, when the access network device is pre-configured with a variety of perception radio resources corresponding to different perception requirements, the message used to indicate the initiation of perception measurement for the perception task can carry information indicating the perception radio resources to be used by the access network device, such as information for indicating the first perception requirement. In this way, it can be ensured that the access network device performs the perception task as required, thereby obtaining a perception result that meets the requirements of the perception task.

[0018] Further, after configuring the perception wireless resources corresponding to the first perception requirement according to the third message, or after configuring the perception wireless resources corresponding to multiple different perception requirements according to the third message, the method described in the first aspect also includes: receiving a fifth message, and the fifth message is used to indicate the initiation of perception measurement for the perception task.

[0019] Furthermore, the fifth message carries third time information, and the third time information is used to indicate the time of sending the first perception measurement result, and the first perception measurement result is the result obtained by measuring based on the first perception requirement in the perception task. In this way, the first network element can flexibly set the time for the access network device to report the first perception measurement result according to actual conditions.

The method includes: receiving a first message, and sending a second message based on the first message; wherein the first message carries a first perception measurement result, the first perception measurement result is a result obtained by measuring in a perception task based on a first perception requirement, and the second message carries information for indicating a second perception requirement, the second perception requirement is used for the perception task, and the second perception requirement is different from the first perception requirement.

[0021] In a possible design scheme, the second message carries first indication information, where the first indication information is used to indicate a second beam that performs a perception task based on a second perception requirement.

[0022] Optionally, the first indication information is location information or direction information.

[0023] Furthermore, the direction information is a departure angle direction or a transmission direction.

[0025] Furthermore, the beam information is a beam number and / or a transmission direction of the beam.

[0026] In a possible design scheme, the second message also carries first time information, where the first time information is used to indicate a time for receiving a second perception measurement result, where the second perception measurement result is a result measured in the perception task based on the second perception requirement.

[0027] In a possible design scheme, before receiving the first message, the method described in the second aspect also includes: sending a third message carrying information for indicating the first perception requirement.

[0028] In a possible design scheme, before receiving the first message, the method described in the second aspect also includes: sending a third message, the third message carries information indicating multiple different perception requirements, and the multiple different perception requirements include the first perception requirement and the second perception requirement.

[0029] Optionally, the third message further carries second time information, where the second time information is used to indicate a time for receiving a first perception measurement result, where the first perception measurement result is a result obtained by measuring in the perception task based on the first perception requirement.

[0030] Optionally, the fifth message carries information indicating the first perception requirement.

[0031] Optionally, after sending the third message, the method described in the second aspect also includes: receiving a fourth message, and sending a fifth message based on the fourth message; wherein the fourth message is used to indicate that the perception wireless resources corresponding to the third message have been configured, and the fifth message is used to indicate the initiation of perception measurement for the perception task.

[0032] Furthermore, the fifth message also carries third time information, where the third time information is used to indicate the time of receiving the first perception measurement result, where the first perception measurement result is a result obtained by measuring in the perception task based on the first perception requirement.

[0068] For ease of understanding, the technical terms involved in the embodiments of the present application are first introduced below.

[0069] 1. Communication and perception integration

[0070] like Figure 1 As shown in the figure, communication and perception integration is a key technology in the next generation of wireless communication systems. It aims to integrate wireless communication and perception functions into the same system, and use the various propagation characteristics of wireless signals to achieve perception functions such as positioning, detection, imaging and identification of targets, so as to obtain information about the surrounding physical environment, improve communication performance and enhance user experience. In the communication and perception integration technology, network devices sense by sending perception signals and receiving echo signals to obtain information such as the location and speed of targets in the environment.

[0071] Among them, the perception signal may refer to a signal used to perceive a target or detect a target, or the perception signal may refer to a signal used to perceive environmental information or detect environmental information. For example, the perception signal may be an electromagnetic wave sent by a network device for perceiving environmental information. The perception signal may also be called a radar signal, a radar perception signal, a detection signal, a radar detection signal, an environmental perception signal, etc., without limitation.

[0072] The echo signal is a signal generated by the perception signal being reflected by a target in the environment. The time delay of the echo signal relative to the sent perception signal reflects the distance of the target; the Doppler frequency shift of the echo signal relative to the sent perception signal reflects the speed of the target.

[0073] The target (or perceived target) may include various tangible objects on the ground that can be perceived, such as mountains, forests, or buildings, and may also include movable objects such as vehicles, drones, pedestrians, and terminal devices. The target is a target that can be perceived by a network device with a perception function, and the target can feedback electromagnetic waves to the network device. The target may also be called a detected target, a perceived object, a detected object, or a perceived device, etc., without limitation.

[0074] 2. Perception Mode

[0075] Perception can usually be divided into: single-station perception and dual-station perception. In single-station perception, the transmitter and receiver of the perception signal are the same device. From the perspective of the perception signal process, the perception site must both send the perception signal and receive the signal reflected by the target surface. Therefore, the single-station perception mode is also called the self-transmitting and self-receiving mode. For dual-station perception, the transmitter and receiver of the perception signal are two different devices. From the perspective of the perception signal process, after the perception site A sends the perception signal, the signal reflected by the target surface is received by the perception site B. Therefore, the dual-station perception mode is also called the A-transmitting and B-receiving mode.

[0076] like Figure 2 As shown, in the current 3rd generation partnership project (3GPP) discussion, it has been determined that the perception mode can be divided into the following 6 modes:

[0077] 1) Base station sends and receives signals on its own: The sensing signal is sent by the base station, reflected by the target in the environment, and then the echo signal is received by the base station.

[0078] 2) Base station A sends and base station B receives: The sensing signal is sent by base station A, reflected by the target in the environment, and then the echo signal is received by base station B.

[0079] 3) Base station sends and terminal receives: The sensing signal is sent by the base station, reflected by the target in the environment, and then the echo signal is received by the terminal.

[0080] 4) Terminal sends and base station receives: The sensing signal is sent by the terminal, reflected by the target in the environment, and then the echo signal is received by the base station.

[0081] 5) Terminal self-transmission and self-reception: The sensing signal is sent by the terminal, reflected by the target in the environment, and then the echo signal is received by the terminal.

[0082] 6) Terminal A sends and terminal B receives: The perception signal is sent by terminal A, reflected by the target in the environment, and then the echo signal is received by terminal B.

[0083] 3. Beam

[0084] Beaming refers to a special directional transmission or reception effect formed by the transmitter or receiver of a network device or terminal through an antenna array, similar to the beam formed by a flashlight converging light in one direction. Sending and receiving signals in the form of beams can effectively increase the transmission distance of signals.

[0085] The beam may be a wide beam, a narrow beam, or other types of beams. The beam forming technology may be a beam forming technology or other technologies. The beam forming technology may specifically be a digital beam forming technology, an analog beam forming technology, or a hybrid digital / analog beam forming technology.

[0086] Beams generally correspond to resources. For example, when performing beam measurement, the network device measures different beams through different resources, and the terminal feeds back the measured resource quality, so that the network device can know the quality of the corresponding beam. During data transmission, the beam can also be indicated by its corresponding resource. For example, the network device indicates a transmission configuration indication-state through the transmission configuration index (TCI) field in the downlink control information (DCI), and the terminal determines the beam corresponding to the reference resource based on the reference resource contained in the TCI-state.

[0087] In the communication protocol, the beam can be specifically characterized as a digital beam, an analog beam, a spatial domain filter, a spatial filter, a spatial parameter, TCI, a TCI-state, etc. The beam used to send a signal can be called a transmission beam (or Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, etc. The beam used to receive a signal can be called a reception beam (or Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, etc.

[0088] It can be understood that the embodiments of the present application are uniformly described using beams, but beams can be replaced by other equivalent concepts and are not limited to the concepts mentioned above.

[0089] During the perception process, when the core network device instructs the access network device to perform the perception task, it will send the perception requirements corresponding to the perception task to the access network device, such as the perception location accuracy requirement, the rate accuracy requirement, the perception allocation rate requirement, etc.; after receiving the perception requirements from the core network, the access network device will configure the corresponding perception wireless resources according to the perception requirements, such as time domain resources, frequency domain resources, airspace resources, etc., and perform the perception task based on the perception wireless resources to obtain the perception results. In other words, the access network device performs the perception task based on a set of perception wireless resources, that is, the perception wireless resources will not change during the process of the access network device performing the perception task. It can be understood that in the embodiments of the present application, "perception requirements" are only an exemplary expression, and "perception requirements" can also be replaced by any possible expression, such as "perception requirements", "perception quality of service (QoS)", etc., without limitation.

[0090] However, in a perception task, there may be multiple different perception states. For example, at the beginning of the perception task, it is necessary to perform perception measurement on objects in the surrounding environment, and after measuring the object, it is necessary to continuously locate the target object in the object. In this case, using only one set of perception wireless resources for perception measurement cannot cope with different perception states in the perception process, or the requirements of the perception task have changed. In this case, how to perform the perception task and improve the perception performance is an urgent problem to be solved.

[0091] In response to the above technical problems, the embodiments of the present application propose the following technical solutions to improve the perception performance.

[0092] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0093] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as 4th generation (4G) mobile communication systems, such as long term evolution (LTE) systems, 5th generation (5G) mobile communication systems, such as new radio (NR) systems, and communication systems evolved after 5G, such as 6th generation (6G) mobile communication systems. They can also be applied to wireless fidelity (WiFi) systems, vehicle to everything (V2X) communication systems, device-to-device (D2D) communication systems, vehicle networking communication systems, etc., and can also be applied to open access networks (open RAN, O-RAN or ORAN), cloud radio access networks (cloud radio access network, CRAN), or two or more of the above communication networks.

[0100] Among them, the access network device can be a device with wireless transceiver functions, or it can also be a chip or chip system set in the device, located in the access network (AN) of the communication system, to provide access services for the terminal. For example, the access network device can be called a radio access network device (RAN) device, which can be a next-generation mobile communication system, such as a 6G access network device, such as a 6G base station, or in the next-generation mobile communication system, the network device can also have other naming methods, which are all covered within the protection scope of the embodiments of the present application, and the present application does not make any limitation on this. Alternatively, the network device may also include 5G, such as a gNB in ​​a new radio (NR) system, or one or a group of antenna panels (including multiple antenna panels) of a base station in 5G, or a network node constituting a gNB, a transmission point (TRP or transmission point, TP) or a transmission measurement function (TMF), such as a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), a roadside unit (RSU) with base station function, or a wired access gateway, or a core network element of 5G. Alternatively, the network device may also include: an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, various forms of macro base stations, micro base stations (also called small stations), relay stations, access points, wearable devices, vehicle-mounted devices, etc. The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete the functions of part of the physical layer or all of the physical layer. For the specific description of the above-mentioned protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP).CU and DU may be separately configured, or may be included in the same network element, such as a baseband unit (BBU). RU may 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). In different systems, CU, DU or RU may have different names, but those skilled in the art may understand their meanings. For example, in an ORAN system, CU may also be referred to as O-CU (open CU), DU may also be referred to as O-DU, and RU may also be referred to as O-RU. Any of the CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0101] The first network element is responsible for the relevant content of the perception operation, such as participating in receiving the perception service request and obtaining the corresponding perception requirements, selecting and requesting the relevant perception equipment to perform the perception operation and receive the corresponding perception measurement data, and opening the perception measurement data or the perception results obtained based on the perception measurement data to the perception requester. The first network element can be a sensing function (SF) network element, or other network elements with the aforementioned functions; the first network element can also be a core network device, without limitation

[0102] In a communication system, the access network device can report the first perception measurement result obtained based on the first perception requirement to the first network element during the execution of the perception task, so that the first network element can adjust the perception requirement based on the first perception measurement result; after the access network device receives the adjusted perception requirement (i.e., the second perception requirement), it can configure the wireless perception resources corresponding to the second perception requirement, and continue to perform perception measurement based on the wireless perception resources. In other words, the access network device can use multiple sets of perception wireless resources to perform perception tasks to cope with various perception states of the perception tasks. In this way, the access network device can obtain perception results that meet the requirements of the perception task and improve the perception performance.

[0103] Understandably, Figure 3 The simplified schematic diagram is provided for ease of understanding. The communication system may also include other network devices and / or other terminal devices. Figure 3 Not drawn.

[0104] For ease of understanding, the following will combine Figure 4 The communication method provided in the embodiments of the present application is specifically described.

[0105] For example, Figure 4 A flow chart of a communication method provided in an embodiment of the present application. The method can be applied to the communication between the access network device and the first network element in the above communication system.

[0106] like Figure 4 As shown, the process of the communication method is as follows:

[0107] S401: An access network device sends a first message. Correspondingly, a first network element receives the first message from the access network device.

[0108] The first message is used to indicate a first perception measurement result obtained by measuring in the perception task based on the first perception requirement, such as the first message carries the first perception measurement result.

[0109] The perception requirement is a requirement for the perception QoS of the perception task, which may include parameters such as perception accuracy, resolution, area, omnidirectional beam, directional beam, etc., and it may be determined according to the perception task. The first perception requirement is a perception QoS requirement for the perception task. That is to say, in an embodiment of the present application, a perception task may have multiple perception requirements, and different perception requirements may be used correspondingly at different stages of the perception task, for example: at the beginning of perception task #c, perception measurement is performed based on perception requirement #a; after a preset time period, perception measurement may be performed based on perception requirement #b until the perception task #c ends.

[0110] The first perception measurement result is the result obtained by measuring in the perception task based on the first perception requirement, which includes the results obtained by measuring on different beams (recorded as result #1). For example: in the perception task, based on the first perception requirement, result #a is measured on beam #A, and result #b is measured on beam #B, then the first perception measurement result includes result #a and result #b. The first perception measurement result can be the original signal data obtained by measurement, or it can be the channel state information after signal processing, such as the amplitude and phase information of the signal, or other data, such as Doppler velocity spectrum, distance spectrum, angle spectrum, etc., which can be set according to actual conditions, and the embodiments of the present application do not limit this. It can be understood that by processing the first perception measurement result, the perceived object and the position, velocity and other information of the perceived object perceived and measured in the perception task can be determined, and the specific processing method is not limited in this application.

[0111] It can be understood that in the embodiment of the present application, "first perception measurement result" is only an exemplary expression, and "first perception measurement result" can also be replaced by any possible expression, such as "first perception measurement data", "first perception data", etc., without limitation.

[0112] Optionally, the first message also carries beam information of the first beam corresponding to the first perception measurement result.

[0113] The first beam is the beam that measures the first perception measurement result, which includes beam #1 that measures result #1, that is, each result #1 in the first perception measurement result corresponds to each beam #1 in the first beam. Continuing with the above example, the first beam includes beam #A and beam #B, result #a is measured by beam #A, and result #b is measured by beam #B, so beam #A corresponds to result #a, and beam #B corresponds to result #b. Beam information can be used to indicate different beams, that is, each beam can be determined by beam information of different beams. The beam information can be a beam number and / or a transmission direction of the beam, for example: the beam information of beam #1 can be the number #1 corresponding to beam #1, or the beam information of beam #1 can be the transmission direction #1, or the beam information of beam #1 can be the number #1 and the transmission direction #1, and beam #1 can be determined by the number #1 and / or the transmission direction #1.

[0114] It can be understood that the access network device can perform perception measurement under line of sight (LOS) conditions or under non-line of sight (NLOS) conditions. For LOS conditions, there are no obstructions between the access network device and the perceived object, and the perception beam of the access network device is on the direct path, so the direction of the perception beam is the direction of the perceived object relative to the access network device, that is, the perception beam can be determined by the position of the perceived object. In this case, the first message may not carry the beam information of the first beam, that is, the beam corresponding to each result #1 in the first perception measurement result can be determined by the position corresponding to each result #1. For NLOS conditions, there are obstructions between the access network device and the perceived object, and the perception beam of the access network device is on the scattering path, so the direction of the perception beam may be different from the position of the perceived object, that is, the beam determined only by the position of the perceived object may be incorrect. In this case, the first message needs to carry the beam information of the first beam, and correspond each result #1 in the first perception measurement result to each beam #1 in the first beam one by one, so as to accurately indicate the beam corresponding to each result #1 in the first perception measurement result.

[0115] S402: The first network element sends a second message according to the first message. Correspondingly, the access network device receives the second message from the first network element.

[0116] The second message may be used to indicate the second perception requirement, such as the second message carries information used to indicate the second perception requirement.

[0117] The second perception requirement is used for the above-mentioned perception task, that is, the second perception requirement is a perception QoS requirement for the perception task. The second perception requirement and the first perception requirement are requirements for two adjacent stages of the perception task, such as the first perception requirement is a requirement for the perception task to perform perception measurement in the first time period, and the second perception requirement is a requirement for the perception task to perform perception measurement in the second time period, the first time period and the second time period are adjacent, and the first time period is before the second time period. The second perception requirement is different from the first perception requirement, that is, the two can be completely different or partially different, for example: the first perception requirement includes perception accuracy #1, resolution #1, and directional beam, the second perception requirement includes perception accuracy #2, resolution #1, and directional beam, and perception accuracy #1 and perception accuracy #2 are different, that is, the second perception requirement is partially different from the first perception requirement; for another example: the first perception requirement includes location accuracy #1 and perception accuracy #1, the second perception requirement includes location accuracy #2 and perception accuracy #2, location accuracy #1 is different from location accuracy #2, and perception accuracy #1 is different from perception accuracy #2, that is, the second perception requirement is completely different from the first perception requirement.

[0118] The information used to indicate the second perception requirement may be information of specific requirements corresponding to the second perception requirement, such as: perception accuracy of 80%, location accuracy of 60%, etc.; it may also be a numerical value agreed upon by the first network element and the access network device to indicate the second perception requirement, such as: for perception task #11, the first network element and the access network device pre-set the perception requirements #a1-perception requirements #a4 that may correspond to the perception task #11, or the first network element sends the perception requirements #a1-perception requirements #a4 corresponding to the perception task #11 to the access network device in advance, and the access network device pre-configures the perception wireless resources corresponding to the perception requirements #a1-perception requirements #a4; wherein, the perception requirements #a1-perception requirements #a4 are indicated by bits 00, 01, 10, and 11, respectively. In this case, the information used to indicate the second perception requirement may be 00, 01, 10, or 11. For example, when the first network element indicates perception requirement #a1, 00 may be carried in the first message.

[0119] The first network element can determine the next perception state of the perception task based on the information carried by the first message; then determine the second perception requirement based on the perception state, and indicate the second perception requirement to the access network device through the second message, so that the access network device updates the perception wireless resource configuration according to the second perception requirement, and uses the updated perception wireless resources to perform perception measurement.

[0120] Exemplarily, the first network element processes the first perception measurement result and can determine the first perceived object corresponding to the first perception measurement result, where the first perceived object is an object (such as a vehicle, a drone, etc.) measured based on the first perception requirement in the perception task. Then, the first network element can determine the second perceived object based on the first perceived object, and the access network device needs to perceive the second perceived object according to the second perception requirement. It can be understood that the second perceived object can be a target of interest determined by the first network element based on the first perceived object, or it can be a target determined based on the first perceived object according to a preset rule, without limitation.

[0121] For example, the first network element obtains perceived objects #1-perceived objects #15 (first perceived objects) through the first perception measurement result, that is, perceived objects #1-perceived objects #15 are objects measured based on the first perception requirement in the perception task; then, the first network element determines perceived objects #1-perceived objects #4 (second perceived objects) from perceived objects #1-perceived objects #15; then, based on perceived objects #1-perceived objects #4, the first network element determines the second perception requirement, and sends the second perception requirement to the access network device through a second message.

[0122] It can be understood that if the first network element does not determine the second perceived object based on the first perceived object, such as does not determine the target of interest, then the first network element may send a perception requirement different from the first perception requirement to the access network device, such as a second perception requirement. The perception requirement may be lower or higher than the QoS of the first perception requirement, and may be set specifically according to actual conditions; or, the first network element may not send the second perception requirement to the access network device. That is to say, in this case, the access network device may continue to perform perception measurements according to the first perception requirement.

[0123] Optionally, the second message carries first indication information, where the first indication information is used to indicate a second beam that performs a perception task based on a second perception requirement, and the second beam is used to indicate a beam used to measure a second perceived object.

[0124] It can be understood that when the conditions for the access network device to perform perception measurement are different, the first indication information may be different, which is introduced below in different situations.

[0125] Case 1: Access network equipment performs perception measurements under LOS conditions.

[0126] In this case, the first indication information may be position information or direction information, such as the first indication information may be position information or direction information of the second perceived object. The position information may be the absolute position of the second perceived object, such as the position of the second perceived object in the absolute coordinate system; or the relative position of the second perceived object, such as the position of the second perceived object in the relative coordinate system of the access network device. The direction information may be the departure angle direction or the emission direction, that is, the direction information may be the departure angle direction or the emission direction of the beam sent by the access network device, and the departure angle direction or the emission direction may be determined by the position between the second perceived object and the access network device.

[0127] For example, the first network element obtains the first perception measurement object and the location information of the first perception measurement object based on the first perception measurement result; then determines the second perception measurement object from the first perception measurement object, and determines the second perception requirement based on the second perception measurement object; then, sends the second perception requirement and the location information of the second perception measurement object to the access network device through a second message, so that the access network device adjusts or updates the perception wireless resources according to the second perception requirement, and determines the beam to execute the perception wireless resource according to the location information; or, sends the second perception requirement and the direction information of the second perception measurement object to the access network device through a second message, so that the access network device adjusts the perception wireless resources according to the second perception requirement, and determines the beam to execute the perception wireless resource according to the direction information.

[0128] In case 1, the direction of the sensing beam is the direction of the sensed object relative to the access network device, that is, the sensing beam can be determined by the position or direction of the sensed object, such as by the position of the sensed object and the position of the access network device. Therefore, the first indication information may be position information or direction information. In this case, the access network device may not carry the beam information of the first beam corresponding to the first sensing measurement result in the first message, so that the communication overhead of the access network device can be reduced.

[0129] Case 2: The access network equipment performs sensing measurements under NLOS conditions and / or LOS conditions.

[0130] In this case, the first indication information may be the beam number of the second beam and / or the transmission direction of the second beam, for example: the first indication information is beam #3-beam #6, or the first indication information is transmission direction #1-transmission direction #3.

[0131] When the access network device performs perception measurement under NLOS conditions, the direction of the perception beam may be different from the position of the perceived object, that is, the perception beam determined by the position of the perceived object is incorrect, that is, the corresponding beam cannot be accurately determined by the position of the perceived object. Therefore, the first message needs to carry the beam information of the first beam corresponding to the first perception measurement result, and each result #1 in the first perception measurement result corresponds one-to-one to each beam #1 in the first beam. In this way, after determining the second perceived object, the first network element can determine the second beam that measures the second perceived object based on the correspondence between the first beam and the first perception measurement result, and send the second beam to the access network device to execute the adjusted wireless perception resources, that is, the wireless perception resources determined based on the second perception requirements.

[0132] It can be understood that in situation 2, the first message carries the beam information of the first beam corresponding to the first perception measurement result, and the second beam belongs to the first beam.

[0133] Optionally, the second message carries first time information.

[0134] The first time information is used to indicate the time of sending or receiving the second perception measurement result, that is, for the access network device, the first time information is used to indicate the time of sending the second perception measurement result; for the first network element, the first time information is used to indicate the time of receiving the second perception measurement result. Exemplarily, the first time information can be a time point, such as: the first time information is 14:00; it can also be the time difference between the first perception measurement result and the first perception measurement result, such as: the first time information is 1 hour (h), which means that the access network device sends the second perception measurement result 1 hour after sending the first perception measurement result, that is, the first network element receives the second perception measurement result 1 hour after receiving the first perception measurement result. It can be understood that the first network element can set the time for the access network device to report the second perception requirement according to the actual situation, for example: if the current perception task needs to be reported frequently, the time corresponding to the first time information can be set shorter, if the current perception task does not need to be reported frequently, the time corresponding to the first time information can be set longer.

[0135] The second perception measurement result is the result obtained by measuring based on the second perception requirement in the perception task, which includes the results measured on different beams. The second perception measurement result is similar to the first perception measurement result. For details, please refer to the relevant description of the aforementioned "first perception measurement result", which will not be repeated here. It can be understood that in the embodiment of the present application, "second perception measurement result" is only an exemplary expression, and the "second perception measurement result" can also be replaced by any possible expression, such as "second perception measurement data", "second perception data", etc., without limitation.

[0136] Carrying the first time information in the second message can indicate the time when the access network device reports the second perception measurement result, so that the access network device reports the second perception measurement result according to the time indicated by the first time information. In this way, it is convenient for the first network element to adjust the perception requirements of the perception task. In addition, the first network element can also flexibly determine the first time information according to actual conditions.

[0137] Optionally, the second message carries a sensing task identifier for indicating the sensing task, so as to indicate which sensing task the second sensing requirement is for, thereby preventing the access network device from using the second sensing requirement for other sensing tasks.

[0138] S403, the access network device performs a perception task based on the second perception requirement.

[0139] That is, after receiving the second message, the access network device can determine the adjusted perception wireless resources according to the second perception requirement carried in the second message, and perform the perception task based on the perception wireless resources.

[0140] It can be understood that when the second message also carries the first indication information, the access network device can also determine the second beam according to the first indication information, and perform the perception task based on the second beam and the adjusted perception wireless resources.

[0141] Optionally, when the second message carries the first time information, after the access network device performs the perception task based on the second perception requirement (i.e., S403), the communication method may further include: the access network device sends the second perception measurement result to the first network element according to the first time information. That is, the access network device may also report the second perception measurement result to the first network element based on the first time information, so that the first network element determines whether to adjust the subsequent perception requirement based on the second perception measurement result.

[0142] In summary, in the embodiment of the present application, the access network device can report the first perception measurement result measured based on the first perception requirement during the execution of the perception task, so that the first network element can adjust the subsequent perception requirement (i.e., the second perception requirement) according to the first perception measurement result, and send the second perception requirement to the access network device; after receiving the second perception requirement, the access network device can configure the wireless perception resource corresponding to the second perception requirement, and continue to perform perception measurement based on the wireless perception resource. In this way, the access network device can configure different perception wireless resources according to the different perception requirements sent by the first network element, so that the results of the measurements based on different perception wireless resources during the perception process can meet the requirements of the perception task and improve the perception performance.

[0143] It is understandable that before the access network device sends the first message (ie before S401), the first network element may send the first perception requirement to the access network device, or the first network element may send multiple perception requirements including the first perception requirement and the second perception requirement to the access network device.

[0144] In a first possible implementation, in combination with the above embodiment, before the access network device sends the first message (that is, before S401), the above communication method may further include: the first network element sends a third message, the third message carries information for indicating the first perception requirement; accordingly, the access network device receives the third message from the first network element ( Figure 4 S400a); the access network device configures the first perception requirement corresponding to the perception wireless resource according to the third message ( Figure 4 (S400b).

[0145] It can be understood that before the first network element sends the third message to the access network device, it has determined that the access network device participates in the perception task. Therefore, the first network element sends the third message to the access network device to request the access network device to configure the perception wireless resources according to the first perception requirement. After receiving the third message, the access network device can configure the perception wireless resources corresponding to the first perception requirement according to the third message.

[0146] Optionally, the third message also carries second time information.

[0147] The second time information is used to indicate the time of sending or receiving the first perception measurement result, and the first perception measurement result is the result measured based on the first perception requirement in the perception task, that is, for the access network device, the first time information is used to indicate the time of sending the first perception measurement result; for the first network element, the first time information is used to indicate the time of receiving the first perception measurement result. Exemplarily, the second time information can be a time point, such as: the second time information is 12:00; it can also be the time difference between receiving the third message and sending the first perception measurement result, such as: the second time information is 2h, which means that the access network device sends the first perception measurement result 2h after receiving the third message. It can be understood that the first network element can set the time for the access network device to report the first perception requirement according to the actual situation, for example: if the current perception task needs to be reported frequently, the time corresponding to the second time information can be set shorter, and if the current perception task does not need to be reported frequently, the time corresponding to the second time information can be set longer. In addition, the second time information and the first time information can be the same or different, and this application does not limit this.

[0148] Carrying the second time information in the third message can indicate the time when the access network device reports the first perception measurement result, so that the access network device reports the first perception measurement result according to the time indicated by the second time information. In this way, it is convenient for the first network element to adjust the perception requirements of the perception task. In addition, the first network element can also flexibly determine the second time information according to actual conditions.

[0149] Optionally, the third message carries a sensing task identifier for indicating the sensing task. In this way, it can be indicated that the third message is a message for the sensing task.

[0150] Optionally, after the access network device configures the perception wireless resources corresponding to the first perception requirement according to the third message, the communication method may further include: the access network device sends a fourth message, the fourth message is used to indicate that the perception wireless resources corresponding to the third message have been configured; accordingly, the first network element receives the fourth message ( Figure 4 S400c); the first network element sends a fifth message according to the fourth message, the fifth message is used to indicate the start of the perception measurement for the perception task; accordingly, the access network device receives the fifth message ( Figure 4 (S400d).

[0151] The perceived wireless resources corresponding to the third message are perceived wireless resources configured based on the first perceived requirements.

[0152] After configuring the perception radio resources corresponding to the first perception requirement, the access network device may send a fourth message to the first network element to indicate that the perception radio resources corresponding to the first perception requirement have been configured. After receiving the fourth message, the first network element may determine, based on the fourth message, that the perception radio resources corresponding to the first perception requirement have been configured in the access network device. At this time, the first network element may send a fifth message to the access network device to instruct the access network device to measure the perception task.

[0153] Optionally, the fifth message carries information for indicating the first perception requirement, and the information for indicating the first perception requirement may be information of specific requirements corresponding to the first perception requirement, such as: the perception accuracy is 70%, the location accuracy is 70%, etc. In this way, the first network element may send the first perception requirement to be used for the perception measurement to the access network device for use when instructing the access network device to start the perception measurement.

[0154] Furthermore, the fifth message carries third time information.

[0155] The third time information is used to indicate the time of sending or receiving the first perception measurement result. The first perception measurement result is the result obtained by measuring based on the first perception requirement in the perception task, that is, for the access network device, the third time information is used to indicate the time of sending the first perception measurement result; for the first network element, the third time information is used to indicate the time of receiving the first perception measurement result. Exemplarily, the third time information can be a time point, such as: the third time information is 12:00; it can also be the time difference between receiving the fifth message and sending the first perception measurement result, such as: the third time information is 2h, which means that the access network device sends the first perception measurement result 2h after receiving the fifth message. It can be understood that the time indicated by the second time information and the third time information is the same. Therefore, the second time information can be carried in the third message, or the third time information can be carried in the fifth message, so that the communication overhead can be reduced.

[0156] Carrying the third time information in the fifth message can indicate the time when the access network device reports the first perception measurement result, so that the access network device reports the first perception measurement result according to the time indicated by the third time information. In this way, it is convenient for the first network element to adjust the perception requirements of the perception task. In addition, the first network element can also flexibly determine the third time information according to actual conditions.

[0157] Furthermore, the fifth message carries a perception task identifier for indicating the perception task.

[0158] In a second possible implementation, in combination with the above embodiment, before the access network device sends the first message (that is, before S401), the communication method further includes: the first network element sends a third message, the third message carries information indicating multiple different perception requirements, and the multiple different perception requirements include the first perception requirement and the second perception requirement; accordingly, the access network device receives the third message ( Figure 4 S400A); the access network device configures a plurality of different perception requirements corresponding to the perception wireless resources according to the third message ( Figure 4 (S400B).

[0159] It can be understood that the first network element can define a variety of different perception states for the perception task. For example, perception task #3 is to first sense and measure whether a perceived power line exists in all directions, and then continuously locate the measured part of the perceived object. For this perception task #3, the first network element can define perception requirement #31 and perception requirement #32. Perception requirement #31 is mainly used to detect whether a perceived object exists, and an omnidirectional beam and coarse-grained perception wireless resources can be configured. Perception requirement #32 is mainly used to continuously locate the perceived object, and a directional beam and fine-grained perception wireless resources can be configured. After defining a variety of different perception states, the first network element can send a variety of different perception requirements to the access network device, so that the access network device pre-configures the perception wireless resources corresponding to the various different perception requirements.

[0160] Optionally, the third message also carries second time information, and the second time information is used to indicate the time of sending the first perception measurement result. For details, please refer to the above-mentioned related introduction, which will not be repeated here.

[0161] Optionally, the third message carries a perception task identifier for indicating the perception task, and details may be referred to the above related introduction, which will not be repeated here.

[0162] Optionally, after the access network device configures the perception wireless resources corresponding to the multiple different perception requirements according to the third message, the communication method may further include: the access network device sends a fourth message, the fourth message is used to indicate that the perception wireless resources corresponding to the third message have been configured; accordingly, the first network element receives the fourth message ( Figure 4 S400C); the first network element sends a fifth message according to the fourth message, the fifth message is used to indicate the start of the perception measurement for the perception task; accordingly, the access network device receives the fifth message ( Figure 4 (S400D).

[0163] The perception wireless resources corresponding to the third message are perception wireless resources configured based on a variety of different perception requirements.

[0164] Optionally, the fifth message carries information for indicating the first perception requirement. The information for indicating the first perception requirement may be a numerical value for indicating the first perception requirement agreed upon by the first network element and the access network device, for example: for perception task #33, the first network element sends the perception requirement #b1-perception requirement #b4 that may correspond to the perception task #22 to the access network device, and the access network device configures the corresponding wireless perception resources according to the perception requirement #b1-perception requirement #b4; wherein the perception requirement #b1-perception requirement #b4 are indicated by bits 00, 01, 10, and 11, respectively. In this case, the information for indicating the first perception requirement may be 00, 01, 10, or 11. For example, when the first network element indicates the perception requirement #b4, 11 may be carried in the first message.

[0165] After configuring the perception radio resources corresponding to the first perception requirement, the access network device may send a fourth message to the first network element to indicate that the perception radio resources corresponding to the multiple different perception requirements have been configured. After receiving the fourth message, the first network element may determine, based on the fourth message, that the perception radio resources corresponding to the first perception requirement have been configured in the access network device. At this time, the first network element may send a fifth message to the access network device to instruct the access network device to measure the perception task.

[0166] Furthermore, the fifth message carries third time information, for which details may be referred to the aforementioned related introduction and will not be repeated here.

[0167] Furthermore, the fifth message carries a perception task identifier for indicating the perception task, and details may be referred to the above related introduction, which will not be repeated here.

[0168] It can be seen that the above content introduces two different situations. The difference between the embodiment corresponding to the first possible implementation and the embodiment corresponding to the second possible implementation is that: in the first possible implementation, the first network element sends the perception requirement to the first network element only when the access network device needs to configure the perception wireless resources corresponding to the perception requirement. Correspondingly, after receiving the perception requirement, the access network device can configure the corresponding perception wireless resources according to the perception requirement and perform the perception task based on the perception wireless resources; in the second possible implementation, the first network element sends a plurality of different perception requirements corresponding to the perception task to the access network device for the perception wireless resource configuration, and when a certain perception requirement among the plurality of different perception requirements is used subsequently, the perception requirement is directly indicated, so that the access network device can switch the perception wireless resources corresponding to different perception requirements. In the two possible implementations, the first network element sends the third message and the fifth message, and the access network device sends the fourth message in a similar manner, and the similarities can be referenced to each other.

[0169] It can be understood that the sending of the first perception request and the second perception request by the first network element can be part of the execution of the perception task. The first network element can also send multiple perception requests according to the actual situation. For example, if the first network element cannot identify the target of interest according to the second perception measurement result, it can also send a third perception request to the access network device, that is, switch the perception state of the perception task; for example, when the first network element determines that the location of the target of interest is beyond the perception range of the access network device, it can also send a perception request to the access network device to switch the perception state of the perception task. In addition, in the process of executing the perception task, if the first network element does not detect the target of interest for a period of time, the first network element can send a session release or deactivation information to end the perception task.

[0170] It is understandable. Figure 4 The communication method is described by taking the execution subject of the access network device or the first network element as an example. It should be understood that when the execution subject of the communication method is the DU in the access network device, Figure 4 The sending or receiving steps performed by the access network device can be replaced by the sending or receiving of the DU, and further can be the sending of the DU to the RU or the receiving of the DU from the RU.
