[0058] It should be understood that the specific embodiments described herein merely exemplify the present application. They are not intended to limit the present application.

[0059] In recent years, wireless sensing technology has attracted more and more attention in the research field. The technology detects the change of a certain characteristic (such as phase, power, eigenvalue, etc.) of the received wireless signal, extracts certain information or characterizes the occurrence of a certain behavior, to meet the expected service or assist in achieving more efficient communication transmission. Therefore, wireless sensing technology can be applied to many scenarios, such as non-touch control (e.g., recognizing gesture actions), old people monitoring (e.g., detecting falling actions), health monitoring (e.g., detecting heartbeats and breathing), weather detection (e.g., identifying rain and snow quantity), unmanned aerial vehicle (UAV) detection (e.g., detecting illegal flying objects), environmental monitoring (e.g., dangerous event alarm), and intelligent traffic assistance, etc. In various sensing applications, sensing algorithms need to rely on sensing measurement data obtained by processing sensing signals, and further analyze the sensing measurement data to obtain the expected sensing results.

[0060] In addition, the application of artificial intelligence / machine learning (AI / ML) in various fields has become a hot research topic. For wireless communication systems, it is desirable to use AI / ML technology to improve network performance, such as data throughput, transmission reliability and coverage, or to reduce algorithm complexity, such as scheduling algorithms, resource overhead and detection algorithms, etc. Unlike traditional mathematical modeling-based methods, in order to obtain better performance, AI / ML methods need a large amount of data for model training.

[0061] When considering the introduction of AI into the fifth generation mobile communication technology (5G) network, the 3rd Generation Partnership Project (3GPP) first considered adding a network data analysis function (NWDAF) in the core network. As a data analysis network element, it is based on network data to automatically perceive and analyze the network, and participates in the network planning, construction, operation and maintenance, network optimization, and operation life cycle, so that the network is easy to maintain and control, improves the efficiency of network resource use, and improves user service experience. It should be noted that the NWDAF collects network data for network maintenance, etc., and does not involve air interface data.

[0062] Therefore, the collection and analysis of data, especially wireless physical layer data, become an indispensable part of future communication systems. The present application considers introducing a communication node with wireless physical layer data collection and distribution functions in future wireless communication systems, especially in indoor wireless coverage environments. Referring to FIG. 1, the communication node collects wireless physical layer data of users in the coverage area and stores it in a storage node, thereby assisting in implementing wireless sensing services and training artificial intelligence models in the coverage range, and achieving the purpose of improving environmental intelligent sensing.

[0063] Based on this, the embodiment of the present application provides a kind of communication node, communication node is the node in wireless access network, FIG. 2 is the component structure schematic diagram of a kind of communication node provided in the embodiment of the present application, as shown in Figure 2, communication node 2 includes:

[0068] The communication node proposed in the present application can be applied to the scenario of short-range wireless communication. Short-range wireless communication refers to data transmission and communication within a relatively short distance (usually within tens of meters) through wireless technology. This communication method does not require traditional wired connection, so it has higher flexibility and convenience. Short-range wireless communication technology is widely used in many fields, such as object recognition, environmental monitoring, positioning and intelligent control. Among them, Starlink or Ambient-Internet of Things (A-IOT) system is a new generation of wireless connection technology in short-range wireless communication. Based on this, the communication node proposed in the present application can be applied to Starlink or A-IOT system to realize communication between different nodes in Starlink or A-IOT system.

[0069] It should be noted that in the embodiments of the present application, the data collection configuration can be determined by the communication node 2 according to the service requirement, or can be determined by other nodes and then sent to the communication node 2 according to the service requirement.

The specific sending process of the measurement signal can be selected according to the actual situation, and the embodiments of the present application do not make specific limitations here.

[0071] It should be noted that in the embodiments of the present application, the measurement data can be physical layer data obtained by the communication node 2 measuring the measurement signal according to the data collection configuration, and the measurement data can also be physical layer data obtained by other nodes measuring the measurement signal sent by the communication node 2 according to the data collection configuration and then sent to the communication node 2. The specific acquisition process of the measurement data can be selected according to the actual situation, and the embodiments of the present application do not make specific limitations here.

[0072] It should be noted that in the embodiments of the present application, the measurement signal can be a physical layer reference signal, and the measurement data can be measurement data obtained according to the physical layer reference signal, such as channel state information (Channel State Information, CSI) or received signal strength information using different beams. The specific measurement signal and measurement data can be determined according to the actual situation, and the embodiments of the present application do not make specific limitations here.

[0073] It should be noted that in the embodiments of the present application, after the communication node 2 obtains the measurement data, the communication node 2 needs to add a data identifier to the measurement data, and then send the measurement data with the added identifier to the storage node for storage. By adding an identifier to the measurement data, it is convenient for subsequent reading of the measurement data.

[0074] In an optional embodiment of the present application, the communication node 2 is a user node, and the user node accesses the management node. The user node includes:

[0075] a first transceiver; and

[0076] a first processor coupled to the first transceiver, wherein the first processor is configured to:

[0077] receive a first measurement signal, and send first measurement data to the management node; wherein the first measurement signal is sent by the management node, the first measurement data is obtained by measuring the first measurement signal based on a first data collection configuration, and the first data collection configuration is determined by the management node according to a first service requirement.

[0078] It should be noted that in the embodiments of the present application, the management node sends the first measurement signal to the user node, the user node obtains the first measurement data by measuring the first measurement signal based on the first data collection configuration, and then sends the first measurement data to the management node.

[0079] Based on the above embodiments, the communication node is the management node, and the management node includes:

[0080] a second transceiver; and

[0081] a second processor coupled to the second transceiver, wherein the second processor is configured to:

[0082] send a first measurement signal to the user node, and receive first measurement data returned by the user node according to the first measurement signal; and

[0083] add a first data identifier to the first measurement data, and send the first measurement data with the added identifier to a storage node for storage; wherein the first data identifier at least includes a collection time of the first measurement data, a data content identifier, and a management node identifier of the management node.

[0084] It should be noted that in the embodiments of the present application, first, the management node can determine the first data collection configuration according to the first service requirement, then the management node sends the first data collection configuration to the user node, subsequently the management node sends the first measurement signal to the user node, the user node obtains the first measurement data by measuring the first measurement signal based on the first data collection configuration, the user node sends the first measurement data to the management node, and finally the management node adds the first data identifier to the received first measurement data, and sends the first measurement data with the added identifier to the storage node for storage.

[0085] For example, referring to FIG. 3, an example data collection method flowchart of a user node according to an embodiment of the present application is provided, which specifically includes the following steps S301 to S307:

[0086] Step S301, the management node determines a first data collection configuration according to a first service requirement.

[0087] Step S302, the management node sends the first data collection configuration to the user node.

[0088] Step S303, the management node sends a first measurement signal to the user node.

[0089] Step S304, the user node receives the first measurement signal, and measures the first measurement signal to obtain first measurement data based on the first data collection configuration.

[0090] Step S305, the user node sends the first measurement data to the management node.

[0091] Step S306, the management node adds a first data identifier to the first measurement data.

[0092] Step S307, the management node sends the first measurement data with the added identifier to the storage node for storage.

[0093] Specifically, the first data identifier includes at least the following contents:

[0094] (1) Collection time: marking the data collection start time, sampling interval and collection duration of the first measurement data.

[0095] (2) Data content identifier: marking the specific content of the first measurement data, such as CSI or signal strength, etc.

[0096] (3) Management node identifier: marking the collection management node, such as the identity certificate identifier (Identity Document, ID) of the management node, etc.

[0097] Further, the first data identifier can also include the following contents:

[0098] (4) Signal configuration: marking the format configuration of the first measurement signal, such as time-frequency resource, transmit power, number of antenna ports, etc.

[0099] (5) Format identifier: marking the quantization format of the first measurement data.

[0100] (6) Location identifier: marking the location or area information of the first measurement data collection.

[0101] Therefore, the first measurement data can be exemplarily identified as <management node identifier, data content identifier, collection time, signal configuration, format identifier, location identifier> in the storage node.

[0102] Further, since the first measurement data is the measurement data obtained by the management node in this scenario through the transmission and reception of specific configuration signals, i.e. the first measurement signal, the first measurement data needs to add the signal configuration of the first measurement signal. At the same time, since the first measurement data is collected and identified by the management node, all user nodes under this management node can apply to access the first measurement data.

[0103] In an alternative embodiment of the present application, the communication node 2 is a user node, wherein the first processor is configured to:

[0104] spontaneously collect the second measurement signal; and

[0105] add a second data identifier to the second measurement data; and send the second measurement data with the added identifier to the management node; wherein the second measurement data is obtained by measuring the second measurement signal based on a second data collection configuration determined by the user node according to a second service requirement; and the second data identifier comprises at least a collection time of the second measurement data, a data content identifier, and a user node identifier of the user node.

[0106] It should be noted that in the embodiments of the present application, the user node can determine the data content and format required to be collected according to the second service requirement, i.e., the second data collection configuration. First, the user node spontaneously collects the second measurement signal, and obtains the second measurement data by measuring the second measurement signal based on the second data collection configuration. Then, the user node adds a second data identifier to the second measurement data. Finally, the user node sends the second measurement data with the added identifier to the management node.

[0107] It should be noted that in the embodiments of the present application, since the user node needs to store the second measurement data into the storage node through the management node, it is necessary to apply for corresponding air interface resources from the air interface, and the existing uplink data transmission mode in the existing communication system can be considered to send the second measurement data with the added identifier to the management node.

[0108] Based on the above embodiments, the communication node 2 is a management node, and the second processor is configured to:

[0109] receive the second measurement data with the added identifier; add a management node identifier of the management node to the second measurement data with the added identifier; and

[0110] send the second measurement data with the twice added identifier to the storage node for storage.

[0111] It should be noted that in the embodiments of the present application, after the management node receives the second measurement data with the added identifier from the user node, since the user node needs to store the second measurement data into the storage node through the management node, the management node also needs to add a management node identifier of the management node to the second measurement data with the added identifier, and the management node sends the second measurement data with the twice added identifier to the storage node for storage.

[0112] For example, referring to FIG. 4, a second exemplary data collection method flowchart of a user node according to an embodiment of the present application is provided, which specifically includes the following steps S401 to S407:

[0113] Step S401, the user node determines a second data collection configuration according to a second service requirement.

[0114] Step S402, the user node spontaneously collects the second measurement signal.

[0115] Step S403, the user node measures the second measurement signal based on the second data collection configuration to obtain second measurement data.

[0116] Step S404, the user node adds a second data identifier to the second measurement data.

[0117] Step S405, the user node sends the second measurement data with the added identifier to a management node.

[0118] Step S406, the management node adds a management node identifier to the second measurement data with the added identifier.

[0119] Step S407, the management node sends the second measurement data with the twice added identifiers to a storage node for storage.

[0120] Specifically, the second data identifier includes at least the following contents:

[0121] (1) Collection time: marking the data collection start time, sampling interval and collection duration of the second measurement data.

[0122] (2) Data content identifier: marking the specific content of the second measurement data, such as CSI or signal strength, etc.

[0123] (3) User node identifier: marking the user node for collection, such as the ID of the user node, etc.

[0124] Further, the second data identifier can further include the following contents:

[0125] (4) Signal configuration: marking the format configuration of the second measurement signal, such as time-frequency resource, transmission power, number of antenna ports, etc.

[0126] (5) Format identifier: marking the quantization format of the second measurement data.

[0127] (6) Position identifier: marking the position or area information of the second measurement data collection.

[0128] Further, the management node also adds a management node identifier to the second measurement data with the added identifier, and therefore, the second measurement data can be exemplarily identified as <management node identifier, user node identifier, data content identifier, collection time, signal configuration, format identifier, position identifier> in the storage node.

[0129] Further, the second measurement data is collected by the user node in the scene, i.e., the user node obtains the surrounding environment data and the measurement data by spontaneously sending and receiving the second measurement signal. Due to the limitation of the local storage space, the user node can store the second measurement data obtained in the scene in the storage node, and considering the security and privacy, only the user node can access the second measurement data.

[0130] In an optional embodiment of the present application, the communication node 2 is a management node, wherein the second processor is configured to:

[0131] receive the third measurement signal sent by the user node;

[0132] add a third data identifier to the third measurement data, and send the third measurement data with the added identifier to the storage node for storage, wherein the third measurement data is obtained by the management node based on a third data collection configuration after measuring the third measurement signal, the third data collection configuration is determined by the management node according to a third service requirement, and the third data identifier at least includes a collection time of the third measurement data, a data content identifier, a user node identifier of the user node, and a management node identifier of the management node.

[0133] It should be noted that in the embodiments of the present application, first, the management node determines the third data collection configuration according to the third service requirement, then the management node can send the physical layer reference signal configuration and the request to the user node, the user node further sends the third measurement signal to the management node based on the physical layer reference signal configuration and the request, the management node obtains the third measurement data based on the third data collection configuration after measuring the third measurement signal, and finally, the management node adds the third data identifier to the third measurement data, and sends the third measurement data with the added identifier to the storage node for storage.

[0134] For example, referring to FIG. 5, an example data collection method flowchart of the management node according to the embodiments of the present application is provided, which specifically includes the following steps S501 to S506:

[0135] Step S501, the management node determines the third data collection configuration according to the third service requirement.

[0136] Step S502, the management node sends the physical layer reference signal configuration and the request to the user node.

[0137] Step S503, the user node sends the third measurement signal to the management node based on the physical layer reference signal configuration and the request.

[0138] Step S504, the management node obtains the third measurement data based on the third data collection configuration after measuring the third measurement signal.

[0139] Step S505, the management node adds a third data identifier to the third measurement data.

[0140] Step S506, the management node sends the third measurement data with the added identifier to the storage node for storage.

[0141] Specifically, the third data identifier includes at least the following contents:

[0142] (1) Collection time: marking the data collection start time, sampling interval and collection duration of the third measurement data.

[0143] (2) Data content identifier: marking the specific content of the third measurement data, such as CSI or signal strength, etc.

[0144] (3) Management node identifier: marking the collection management node, such as the ID of the management node, etc.

[0145] Further, the third data identifier can also include the following contents:

[0146] (4) Signal configuration: marking the format configuration of the third measurement signal, such as time-frequency resource, transmit power, number of antenna ports, etc.

[0147] (5) Format identifier: marking the quantization format of the third measurement data.

[0148] (6) Location identifier: marking the location or area information of the third measurement data collection.

[0149] Therefore, the third measurement data can be exemplarily identified as <management node identifier, data content identifier, collection time, signal configuration, format identifier, location identifier> in the storage node.

[0150] Further, since the third measurement data is similar to the first measurement data, both of which are measurement data obtained by the management node in the scene through transmitting and receiving specific configuration signals with the user node, the third measurement signal configuration needs to be added to the third measurement data. Since the third measurement data is collected and identified by the management node, all user nodes under the management node can apply to access the third measurement data.

[0151] In an optional embodiment of the present application, the communication node 2 is a management node, wherein the second processor is configured to:

[0168] Therefore, the fourth measurement data can be exemplarily identified as <management node identifier, data content identifier, collection time, format identifier, location identifier> in the storage node.

[0169] Further, the fourth measurement data is collected by the management node in the scenario, i.e., the management node obtains the surrounding environment data and the measurement data by spontaneously collecting the fourth measurement signal, and is irrelevant to the specific user node. The specific fourth measurement data can include the environment data constructed by the management node by spontaneously collecting the signal and the distribution data of the received signal strength fed back by the user node in the average unit coverage area, etc. Since the data is collected by the management node, all the user nodes under the management node can apply to access the fourth measurement data.

[0170] In the embodiment of the present application, after the measurement data is stored into the storage node, the user node can also apply to access the measurement data, and the specific access process is as follows.

[0171] In an optional embodiment of the present application, the communication node 2 is a management node, wherein the second processor is configured to:

[0172] broadcast the service capability of the storage node; the service capability includes the storage data capability and the access data capability of the storage node.

[0173] It should be noted that, in the embodiment of the present application, in order to provide the storage data service and the access data service of the physical layer data to the user nodes in the coverage area, the management node needs to broadcast the service capability of the storage node in its coverage area, i.e., in the supported service types, it is indicated that the management node has the storage capability and the access capability of the physical layer data.

[0174] Based on the above embodiment, the communication node 2 is a user node, wherein the first processor is configured to:

[0175] receive the broadcast information; the broadcast information is broadcasted by the management node, and the broadcast information is used to indicate the service capability; and

[0176] send a data content query request to the management node, and send a data access request to the management node in the case of receiving the first information; the data access request carries a target data content identifier and a target data range; wherein the data content query request includes the target data content identifier to be accessed; and the first information is sent by the management node to the user node in the case of querying the target data content identifier.

[0177] It should be noted that in the embodiments of the present application, the management node broadcasts the service capability of the storage node, and after receiving the broadcast information, the user node first sends a data content query request to the management node, the data content query request including a target data content identifier to be accessed, then the management node sends first information to the user node after querying that the measurement data of the target data content identifier exists in the storage node, and finally, the user node sends a data access request carrying the target data content identifier and a target data range to the management node after receiving the first information, so that the management node provides corresponding access data to the user node.

[0178] Based on the above embodiments, the communication node 2 is a management node, wherein the second processor is configured to:

[0179] receive a data content query request; query the target data content identifier included in the data content query request in a data content identifier list; and

[0180] if the query is successful, send first information to the user node that sent the data content query request; wherein the data content identifier list is sent by the storage node to the management node according to the data content identifier of the received measurement data.

[0181] It should be noted that in the embodiments of the present application, the storage node generates a data content identifier list based on the data content identifier of the received measurement data, and sends the data content identifier list to the management node, the data content identifier list is used to represent that the storage node can provide measurement data corresponding to the following data content, the management node can query the target data content identifier included in the data content query request from the data content identifier list after receiving the data content query request, if the target data content identifier is queried from the data content identifier list, it represents that the storage node can provide this type of data, at this time, the management node can send first information, such as query success information, to the user node.

[0182] Based on the above embodiments, the communication node 2 is a management node, wherein the second processor is configured to:

[0183] receive a data access request; if it is determined that the target data content identifier carried in the data access request belongs to the first type of data content identifier in the data content identifier list, verify the identity of the user node that sent the data content query request; and

[0184] send the target access data to the user node after the identity verification is passed; the target access data is obtained from the storage node according to the target data range carried in the data access request.

[0185] It should be noted that in the embodiment of the present application, after receiving the first information, the user node sends a data access request to the management node. At this time, after receiving the data access request, the management node first needs to determine whether the target data content identifier in the data access request belongs to the first type of data content identifier, i.e., whether the corresponding measurement data belongs to the second measurement data in the above embodiment. Since the second measurement data is obtained by the user node through self-emission and self-reception of the second measurement signal to obtain surrounding environment data and measurement data, and considering safety and privacy, only the user node can access the second measurement data. Therefore, if the target data content identifier, i.e., the corresponding measurement data, belongs to the second measurement data, the identity of the user node needs to be verified, i.e., whether the target data content identifier, i.e., the corresponding measurement data, is pre-stored by the user node applying for access. Then, if the identity verification of the user node is passed, the data access request is forwarded to the storage node. Finally, the storage node provides the target access data to the management node according to the data access request, and the management node sends the target access data to the user node.

[0186] Based on the above embodiment, the communication node 2 is a management node, wherein the second processor is configured to:

[0187] If it is determined that the target data content identifier does not belong to the first type of data content identifier, the target access data is sent to the user node.

[0188] It should be noted that in the embodiment of the present application, the target data content identifier does not belong to the first type of data content identifier, i.e., the target data content identifier, i.e., the corresponding measurement data, does not belong to the second measurement data in the above embodiment. At this time, for the first measurement data, the third measurement data and the fourth measurement data, the management node and all user nodes under the management node can access the data without identity verification. Therefore, if the target data content identifier does not belong to the first type of data content identifier, the management node forwards the data access request to the storage node. Then, the storage node provides the target access data to the management node according to the data access request, and the management node sends the target access data to the user node.

[0189] For example, referring to FIG. 7, an exemplary data access method flowchart of a user node provided by the embodiment of the present application is provided, which specifically includes the following steps S701 to S709:

[0190] Step S701, the storage node sends a data content identifier list to the management node.

[0191] Step S702, the management node broadcasts the service capability of the storage node.

[0192] Step S703, the user node sends a data content query request to the management node.

[0193] Step S704, after the management node queries the target data content identifier in the data content query request from the data content identifier list, the management node sends query success information to the user node.

[0194] Step S705, the user node determines the target data range required according to the service requirement.

[0195] Step S706, the user node sends a data access request carrying the target data content identifier and the target data range to the management node.

[0196] Step S707, if the target data content identifier belongs to the first type of data content identifier, the management node verifies the identity of the user node, and forwards the data access request to the storage node after the identity verification is passed.

[0197] Specifically, if the target data content identifier does not belong to the first type of data content identifier, the management node directly forwards the data access request to the storage node.

[0198] Step S708, the storage node provides the target access data to the management node according to the target data content identifier and the target data range in the data access request.

[0199] Step S709, the management node sends the target access data to the user node.

[0200] It should be noted that in the embodiments of the present application, for the fourth measurement data, the management node can access the collected data to the storage node at any time, for example, querying and obtaining the environmental data of a certain time period from the storage node for sensing application, and if the user node needs to access, for the first measurement data and the third measurement data, the user node can send a data access request to the management node, the management node obtains the data from the storage node and sends it to the user node, for the second measurement data, after the user node sends a data access request to the management node, the management node needs to verify the identity of the user node, and after the identity verification of the user node is passed, the management node obtains the data from the storage node and sends it to the user node. In order to ensure that the required data meets the requirements, the user node needs to send a data content query request to the management node before applying for access to the data, if the required data content is queried, the user node continues to send a data access request to the management node.

[0201] It can be understood that the management node proposed in the present application can support model training and wireless sensing services in an AI / ML-based physical layer in an actual system, where the wireless network can be Wi-Fi, Starlink, or a 3GPP wireless access network, etc.; for example, when a user node has an AI / ML model for CSI compression, after entering the coverage area of the management node, the local model needs to be trained using the data set of the area, so the data set query signaling needs to be sent to the management node, and access to the data set related to CSI compression in the data set is applied. After the management node sends the data set to the user node, the user node trains the local model using the data.
