Description

Technical Field

[0001] This disclosure generally relates to apparatus and methods for data recording. Background Technology

[0002] In mobile networks such as 5G networks, measurement logging is the process of collecting, storing, and managing radio measurement data. This data can be used to support the training of artificial intelligence / machine learning (AI / ML) models for purposes such as beam prediction.

[0003] For example, measurement logs can be used to collect high-quality, real-time data about the radio environment, which can be used to train and improve AI / ML models for beam prediction in 5G networks. This data collection process is designed to be flexible, efficient, and responsive to network conditions.

[0004] The 3GPP Radio Access Network Technical Specification Group (TSG RAN) and RAN Working Group 2 (RAN2) are responsible for radio interface architecture and protocols, and are dedicated to defining a process for measuring and recording data collected during Radio Resource Control (RRC) connected operation to train AI / ML models for beam prediction on the network side (NW side).

[0007] Therefore, for network entities such as network nodes, various triggers can be used to make decisions for activating / deactivating data records at devices (such as user equipment). This enables rapid activation of data records in response to triggers, while maintaining separation between the triggering mechanism and the data recording mechanism. For example, a Layer 3 measurement report triggered by a measurement event can trigger the activation or deactivation of a Layer 1 measurement record.

[0046] As used herein, the term "network device" or "network node" refers to a node in a communication network through which user equipment can access the network and / or which has the ability to control radio communications and manage radio resources within a cell. A network node or network device may be referred to as a base station (BS), access point (AP), or access node. Depending on the technology applied, a network device may be, for example, a Node B (NodeB or NB), an evolved Node B (eNodeB or eNB), an NR NB (also known as a gNB), a Remote Radio Unit (RRU), a Radio Head (RH), a Remote Radio Head (RRH), a relay, an Integrated Access and Backhaul (IAB) node, a low-power node, a non-terrestrial network (NTN) or non-land network device (such as satellite network equipment, low Earth orbit (LEO) satellites, and geostationary Earth orbit (GEO) satellites), or a spacecraft network device.

[0047] Furthermore, in a segmented radio access network (RAN) connection, network equipment can refer to a centralized unit (CU) and / or a distributed unit (DU) of a base station. The interface between the CU and the DU can be referred to as the F1 interface in the NR. In a segmented RAN architecture, node operation can be performed at least partially in a central / centralized unit (CU) (e.g., a server, host, or node) operatively connected to a DU (e.g., a radio head / node). A CU can control one or more DUs, at least acting as a transmit / receive (Tx / Rx) node. In some embodiments, a DU may include, for example, a radio link control (RLC), media access control (MAC) layer, and a physical (PHY) layer, while the CU may include layers above the RLC layer, such as a packet data convergence protocol (PDCP) layer, radio resource control (RRC), and internet protocol (IP) layer. Other functional segmentation is also possible. In practice, any processing task can be performed in a CU or a DU, and the boundaries of responsibility transferred between the CU and the DU can depend on the applied implementation.

[0048] The term "terminal device" refers to any terminal device capable of wireless communication. For example, a terminal device can be referred to as a communication device, communication apparatus, user equipment (UE), subscriber station (SS), or mobile station (MS). Terminal devices can include mobile phones, cellular phones, smartphones, VoIP phones, wireless local loop phones, tablets, wearable terminal devices, personal digital assistants (PDAs), portable computers, desktop computers, image capture terminal devices (such as digital cameras), gaming terminal devices, music storage and recycle bins, in-vehicle wireless terminal devices, USB dongles, Internet of Things (IoT) devices, watches or other wearable devices, head-mounted displays (HMDs), vehicles, drones, medical devices and applications (e.g., remote surgery), industrial devices and applications (e.g., robots and / or other wireless devices operating in industrial and / or automated processing chain environments), consumer electronics devices, devices operating on commercial and / or industrial wireless networks, and so on.

[0049] As used herein, the term "resource" can refer to radio resources in the time domain, frequency domain, spatial domain, and / or code domain. Some examples of resources include, for example, physical resource blocks (PRBs), radio frames, subframes, time slots, subbands, frequency ranges, subcarriers, beams, etc. The terms "transmission" and / or "reception" can refer to wireless transmission and / or reception on radio resources via a radio propagation channel.

[0050] Communication devices, such as user equipment (UE), can record data related to their dominant radio environment. There are several types of measurements that can be recorded by a UE, one of which is Layer 1 (L1) measurement, and the other is Layer 3 (L3) measurement. L1 measurements include unfiltered, raw physical layer data, including, for example, Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal-to-Interference-plus-Noise Ratio (SINR). L3 measurements include filtered and processed (e.g., averaged) measurements of the reference signal (RS), which provide a more stable observation of the radio environment.

[0051] 3GPP RAN2 discusses how a UE can know when to activate and deactivate measurement recording. One approach is to use L3 measurement events, which can be based on Synchronization Signal Block (SSB) RS or Channel State Information (CSI) RS.

[0052] For example, using L3 measurement events as triggers to activate or deactivate L1 measurement recording offers several significant advantages in 5G networks, such as improved data collection efficiency through continuous network monitoring with fewer resource-intensive L3 measurements, while activating more detailed L1 recording only when favorable or useful radio conditions are detected. This optimizes data collection and improves UE battery life. It also enables targeted data collection, ensuring detailed measurements are collected during periods of interest, such as cell edge conditions or potential handover scenarios, which enhances the relevance of data used for AI / ML training.

[0053] This approach reduces the burden on storage and transmission resources by decreasing the total amount of data collected and stored, while still capturing the most relevant information. Furthermore, it enhances anomaly detection capabilities by allowing for detailed investigation of anomalous conditions indicated by L3 events.

[0054] In the current 3GPP specifications, the only action that can be taken based on these L3 mobility events is for the UE to send a measurement report. However, while it is expected that L3 measurement events will be used as triggers to activate or deactivate L1 measurement records, it is not expected that frames will be combined or associated with them.

[0055] According to this disclosure, an apparatus and method are provided that enable a UE to activate a measurement record when the UE is in a location for collecting useful data by associating an L3 event with an L1 measurement record in such a way that the network (NW) can make a decision to activate or deactivate the record during the delay period of activating the log record without causing detectable data loss.

[0056] According to the example, data records (such as measurement records) can be activated or deactivated by the NW in such a way that the triggering is separate from the measurement record configuration. That is, in the example, the NW can trigger the activation or deactivation of the measurement record based on the configuration previously provided to the UE. The NW can trigger the activation or deactivation of the measurement record in response to one or more of the following example stimuli: measurement reports sent from the UE to the NW (e.g., RSRP is greater than a threshold), assessments of UE performance by the NW (e.g., UE throughput is low or below a threshold), and assessments of system performance by the NW (e.g., low throughput of many UEs).

[0057] To enable the NW to control when the UE records measurements, commands are provided to activate or deactivate the recording or to switch the recording state of the data recording configuration. The data recording configuration can be, for example, an L1 measurement recording configuration, an L3 measurement recording configuration, or any other type of recording configuration.

[0058] Based on the example, the command can be implemented in several ways. For instance, a recording activation flag or indication can be added to the UE's recording configuration. This can be utilized using the Radio Resource Control (RRC) reconfiguration process. ToAddMod To set the flag, where mod means to modify the previously provided configuration and allow modifications to the previously provided configuration.

[0059] In another example, a new Media Access Control (MAC) control element (CE) can be defined. The MAC CE can be used, for example, to activate or deactivate a record configuration based on a command, or based on a flag, or to switch the activation state from active to inactive or vice versa. This MAC CE can be further enhanced by including a field that provides an identifier pointing to the measurement record configuration to be executed.

[0060] Figure 1 This is a schematic representation of the message flow for data records, based on the example. Figure 1 In the example, NW 103 (e.g., a gNB in ​​a 5G network) configures (1) UE 101 using a measurement report configuration and a data logging configuration, which can be periodic or event-triggered. The data logging configuration can include a configuration that defines the activation state of measurement logging at UE 101. In the example, such data logging can be initially configured to be either active or deactivated, in which case data logging is enabled at the UE and in which case it is disabled at the UE. Figure 1 In the example, the activation state is disabled (i.e., not activated or deactivated).

[0061] According to the example, the initial state of the data record configuration can be implicitly deactivated or activated, or explicitly deactivated or activated, for example, by a flag.

[0062] exist Figure 1 In the example, the triggering event occurs at point 2. The triggering event may, for example, be entirely within NW 103 (e.g., gNB), or it may be a response to information received from UE 101 (such as a measurement report triggered by a measurement event configured by NW 103) to help determine the activation of a data recording.

[0063] NW 103 can activate data recording (3) based on a report received from UE 101. Then, NW 103 can reconfigure (4) the data recording configuration, where data recording is set to be activated (in this example), and UE 101 can start (5) recording data, for example, using the measurement described above. Therefore, the network can send an RRC reconfiguration message to reconfigure the already provided data recording configuration.

[0064] A triggering event (6) may occur, which may be entirely within the NW 103 (e.g., gNB), or may be a response to information received from the UE 101 (such as a measurement report triggered by a measurement event configured by the NW 103) to help determine the deactivation of the record. The NW 103 may decide (7) to deactivate the data record and thus may reconfigure the data record configuration at the UE 101, where the record is set to be deactivated. Therefore, the UE 101 may stop (9) recording data.

[0065] According to the example, the data to be recorded may include measurement data, such as reference signal received power (RSRP) measurement, reference signal received quality (RSRQ) measurement, positioning reference signal (PRS), beam index, channel state information, location information (e.g., latitude and longitude), or sensor data (e.g., velocity, acceleration, air pressure, etc.).

[0066] Figure 2 This is a schematic representation of the message flow for data records, based on the example. Figure 2 In the example, NW 103 (e.g., a gNB in ​​a 5G network) configures (1) UE 101 using a measurement report configuration and a data logging configuration, which can be periodic or event-triggered. The data logging configuration can include a configuration that defines the activation state of measurement logging at UE 101. In the example, such data logging can be initially configured to be either active or deactivated, in which case data logging is enabled at the UE and in which case it is disabled at the UE. Figure 2In the example, the activation state is disabled (i.e., not activated or deactivated).

[0067] According to the example, the initial state of the data record configuration can be implicitly deactivated or activated, or explicitly deactivated or activated by, for example, a flag.

[0068] exist Figure 2 In the example, the triggering event occurs at point 2. The triggering event may, for example, be entirely within NW 103 (e.g., gNB), or it may be a response to information received from UE 101 (such as a measurement report triggered by a measurement event configured by NW 103) to help determine the activation of a data recording.

[0069] NW 103 can activate data recording (3) based on a report received from UE 101. NW 103 can send a command to UE 101 to: activate measurement recording (4a), or switch measurement recording from inactive to active (4b). Therefore, UE 101 will start (5) recording data.

[0070] A trigger event occurs (6), which may be entirely within the NW 103 (e.g., gNB) or may be a response to information received from the UE 101 (such as a measurement report triggered by a measurement event configured by the NW 103) to help determine the deactivation of the recording. The NW 103 decides (7) to deactivate the measurement recording, and therefore the NW 103 sends a command to the UE 101 to: deactivate the measurement recording (8a), or switch the measurement recording from active to inactive (8b). The UE 101 stops (9) recording data.

[0071] exist Figure 1 In the NW, the UE can adjust whether to activate recording (and thus record data) or deactivate recording (i.e., the UE does not record data) by using RRC reconfiguration messages to update or reject previously sent data recording configurations. On the other hand, in Figure 2 In this context, the NW can use the MAC CE command, regardless of how it commands the UE, to adjust whether the UE should activate recording (and thus record data) or deactivate recording (i.e., the UE should not record data). For example, this command can change field values ​​in the configuration of already transmitted data records.

[0072] Figure 3 This is a schematic representation of the message flow for data records, based on the example. Figure 3 The example provides a message flow specific to the data record activation process for data collection used in AI / ML beam prediction.

[0073] According to the example, UE 101 (by NW 103) is configured using measurement report configuration (1), which eventA1 A measurement report is triggered when the L3 RSRP exceeds the threshold, and its reportOnLeave =True enables UE 101 to also send a measurement report when the triggering condition is no longer met.

[0074] Meanwhile, for data recording, NW 103 will also utilize CSI-ReportConfig Configure UE 101. Figure 3 In the example, the record configuration is set to inactive, or the specification can specify the initial record state.

[0075] UE 101 performs sufficient measurements to trigger from eventA1 The report (2). That is, the measurement events configured by NW103 in (1) above. eventA1 The condition is met, for example, when the RSRP measurement at UE 101 exceeds a predetermined threshold. Therefore, when the measurement event is triggered, UE 101 sends a signal to NW 103. Measurement Report (3). Based on the receipt of the report, NW 103 may decide to activate data recording at UE 101 (4).

[0076] In the example, NW 103 therefore uses csi-ReportConfigToAddModList To reconfigure UE 101, the data recording activation state is changed to active, and UE 101 thus begins recording data (6).

[0077] Subsequently, UE 101 may detect that the measurement event is no longer satisfied. eventA1 Triggering condition (7). That is, the measurement event configured by NW 103 in (1) above. eventA1 The condition is no longer met, for example, when the RSRP measurement at UE 101 is below a predetermined threshold, and UE 101 therefore sends (8) to NW 103. Measurement Report .

[0078] Based on the received report, NW 103 can decide to deactivate the data record (9) at UE 101. Therefore, NW103 uses csi-ReportConfigToAddModList Reconfigure UE 101 to change the record's active state to inactive (10).

[0079] Figure 4 This is a schematic representation of the message flow for data records, based on the example. Figure 4 The example provides a message flow specific to the data record activation process for data collection used in AI / ML beam prediction.

[0080] According to the example, UE 101 (by NW 103) is configured using measurement report configuration (1), which eventA1 A measurement report is triggered when the L3 RSRP exceeds the threshold, and its reportOnLeave =True enables UE 101 to also send a measurement report when the triggering condition is no longer met.

[0081] Meanwhile, for data recording, NW 103 also utilizes CSI-ReportConfig Configure UE 101. Figure 4 In the example, the record configuration is set to inactive, or the specification can specify the initial record state.

[0082] UE 101 performs sufficient measurements to trigger from eventA1 The report (2). That is, the measurement events configured by NW103 in (1) above. eventA1 The condition is met, for example, when the RSRP measurement at UE 101 exceeds a predetermined threshold. Therefore, when the measurement event is triggered, UE 101 sends a signal to NW 103. Measurement Report (3). Based on the receipt of the report, NW 103 may decide to activate the data recording at UE 101 (4).

[0083] In the example, NW 103 sends a MAC CE to UE 101 to either activate data recording (5a) or switch data recording from inactive to active (5b), and UE 101 thus begins recording data (6).

[0084] Subsequently, UE 101 may detect a measurement event. eventA1 The triggering condition is no longer met (7). That is, the measurement event configured by NW 103 in (1) above is no longer met. eventA1 The condition is no longer met, for example, the RSRP measurement at UE 101 is below a predetermined threshold, and UE 101 therefore sends (8) to NW 103. Measurement Report .

[0085] Based on the receipt of the report, NW 103 can decide to deactivate the data record at UE 101 (9). Therefore, NW 103 sends a MAC CE to UE 101 to: deactivate the measurement record (10a), or switch the measurement record from active to inactive (10b).

[0086] For example, as referenced above Figure 3 The following includes pseudocode for RRC Configuration and RRC Reconfiguration scenarios.

[0087] DataLoggingConfigToAddModList ::= SEQUENCE (SIZE (1..maxNrOfConfigs)) OF DataLoggingConfig DataLoggingConfigToRemoveList ::= SEQUENCE (SIZE (1..maxNrOfConfigs)) OF DataLoggingConfigId DataLoggingConfiguration ::= SEQUENCE { dataLoggingConfigId DataLoggingConfigId, <data logging configuration information elements> [alt 1] activationState ENUMERATED { activated, deactivated} OPTIONAL --Need M [alt 2] activateNULL OPTIONAL, -- Need N deactivate NULL OPTIONAL -- Need N [alt 3] toggleActivation NULL OPTIONAL -- Need N } In "alt 1"—the data recording configuration for UE 101 can initially utilize either an active or deactivated state. activationState Configure it. The reconfiguration process, which modifies the data record configuration based on data record control commands, allows control over the active or inactive state.

[0088] In “alt 2”, the data record configuration for UE 101 can be specified as initially active or inactive. To activate a data record, the reconfiguration procedure can be used to provide the command “activate”. To deactivate a data record, the reconfiguration procedure can be used to provide the command “deactivate”. In the example, only one command is provided to UE 101.

[0089] In “alt 3”, the data logging configuration for UE 101 can be specified as initially active or inactive. To switch the active state, i.e., from active to inactive or from inactive to active, the reconfiguration process can be provided by the command “toggleActivation”.

[0090] For example, in the above reference Figure 4 In the context of the described example (MAC CE case), an ID corresponding to the data record configuration can be provided to UE 101. The data record configuration can be shared across all data record configuration types, or a separate MAC CE can be defined for each data record configuration type, such that the data record configuration ID corresponds to the ID defined for that data record configuration type.

[0091] The following presents the data logging command MAC CE based on the example, where the data logging configuration ID, as described above, is appended with the reserved field "R / CMD".

[0092]

[0093] In one example, the R / CMD field in the data logging command MAC CE can be considered as the "Reserved (R)" field, and the entire MAC CE can correspond to the command "Activate".

[0094] In another example, the R / CMD field in the data logging command MAC CE can be considered as the "Reserve (R)" field, and the entire MAC CE can correspond to the command "Deactivate".

[0095] In another example, the R / CMD field in the data logging command MAC CE can be considered as the "Reserve (R)" field, and the entire MAC CE can correspond to the command "Toggle". When this MAC CE is received, if the current state is inactive, UE 101 activates data logging, and if the current state is active, UE can deactivate data logging.

[0096] In another example, the R / CMD field in the data logging command MAC CE can be considered a command field, with a value of 1, for example, corresponding to the command "activate" and a value of 0, for example, corresponding to the command "deactivate".

[0097] As an example, to support the activation or deactivation of data records through configuration, new, modifiable, or updatable fields can be added to the configuration for measurement records.

[0098] Figure 5 This is a schematic representation of the message flow based on the example. Figure 5 The example depicts the initial configuration of a data record at UE 101, where the record is initially either inactive or initially active. Updates to the configuration can be used to change the record's activation state.

[0099] In the example, the data logging control commands include commands from NW 103 to UE 101 to adjust the activation state for data logging at UE 101. Data logging control commands can be used to update configurations to, for example, change the recording activation state of the UE, and such commands can be implemented in various ways.

[0100] For example, in the above references Figure 1 and Figure 2 In the case of the described process, two commands can be defined: one for activation and the other for deactivation, for example, such as Figure 6 As shown.

[0101] In another example, for example, such as Figure 7 As shown, a single command, including flags, can be defined for activation and deactivation.

[0102] In another example, for example, such as Figure 8 As shown, a single command can be defined that switches the current state from active to inactive or from inactive to active.

[0103] In another example, one or two commands can be used to activate and deactivate explicitly or via switches, and an identifier pointing to the measurement record configuration to be activated or deactivated is also provided.

[0104] In other words, for example, the identifier can be related to the above references. Figures 6 to 8 Any examples described are included together. Identifiers may point to measurement configurations that are extended to support existing types of data recording, such as CSI-ReportConfig , ReportConfigNR Or it could point to any other new type of measurement configuration that supports data logging.

[0105] In the example, the identifier can share the index of the data record configuration, or the identifier can point to a virtual index that only considers the data record configuration and excludes the immediate reporting configuration from the index.

[0106] In an embodiment, an apparatus is provided, comprising: at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus (which may be a UE) to at least: receive a data recording configuration from a network entity; receive a Media Access Control (MAC) control element (CE) from the network entity, the MAC CE being configured to adjust an activation state for data recording at the apparatus; and determine, based on a dominant activation state at the apparatus, whether to record data at the apparatus. The apparatus may also be configured to receive a measurement report configuration from the network entity, the measurement report configuration indicating at least one triggering event for triggering the generation of a measurement report for the apparatus.

A box described in one flowchart may be combined with a box in another flowchart. In some examples, some boxes in a flowchart may be unnecessary and / or additional boxes may be added. It should be understood that each flow and / or box in a flowchart and / or block diagram, and combinations of flows and / or diagrams in flowcharts and / or block diagrams, can be implemented using machine-readable instructions.

In particular, a processor or processing device can execute machine-readable instructions. Therefore, modules of a device can be implemented by a processor that executes machine-readable instructions stored in memory or by a processor that operates according to instructions embedded in logic circuitry. The term "processor" should be interpreted broadly to include CPUs, processing units, ASICs, logic units, or programmable gate arrays, etc. Methods and modules can be executed entirely by a single processor or divided among several processors.
