AI Technical Summary
Current wireless communication systems lack efficient mechanisms for radio access network (RAN) coordinated user equipment (UE) data management, which hinders optimal network performance and resource allocation.
The method involves a network node receiving a data collection configuration from a server and transmitting a data collection indication to a UE, prompting it to collect data and send a report. This process can be autonomously initiated by the UE based on RAN-configured conditions.
This approach enables improved data collection and reporting, enhancing model training and network optimization, while reducing power and resource utilization.

Description
RADIO ACCESS NETWORK COORDINATED USER EQUIPMENT DATA MANAGEMENT
[0001] FIELD OF THE DISCLOSURE
[0002] Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for radio access network coordinated user equipment data management.BACKGROUND
[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like) . Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE) . LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP) .
[0004] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as a user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. “Downlink” (or “DL” ) refers to a communication link from the network node to the UE, and “uplink” (or “UL” ) refers to a communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via a local link (e.g., a sidelink (SL) , a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, among other examples) .
[0005] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, and / or global level. New Radio (NR) , which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM and / or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM) ) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.SUMMARY

[0029] With respect to artificial intelligence (AI) and / or machine learning (ML) , a user equipment (UE) may be equipped with various models or model structures depending on the AI / ML features or functionality. There may be times, however, when data that is collected for the various models or model structures is dependent on configurations of a radio access network (RAN) .
[0030] Some aspects described herein enable RAN coordinated UE data management. For example, a network node may use signaling to receive a data collection configuration from a server (e.g., an application server) and deploy the data collection configuration to a UE. When a data collection event occurs, the network node may transmit signaling to cause the UE to collect data regarding a network and transmit a data collection report to the network node and / or the server. Additionally, or alternatively, the network node may configure the UE to autonomously detect an occurrence of a data collection event, initiate data collection, and transmit a data collection report. In this way, the UE can collect data in accordance with a RAN configuration or condition, which may enable improved model training and / or deployment relative to data collection that occurs without RAN involvement, as described in more detail herein. Based at least in part on enabling data collection, the UE and a network node can optimize a network and / or reduce a utilization of power or network resources or increase an efficiency of network resource allocation.
[0031] Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. One skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.
[0032] Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as “elements” ) . These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.
[0033] While aspects may be described herein using terminology commonly associated with a 5G or New Radio (NR) radio access technology (RAT) , aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and / or a RAT subsequent to 5G (e.g., 6G) .
[0034] Fig. 1 is a diagram illustrating an example of a wireless network 100, in accordance with the present disclosure. The wireless network 100 may be or may include elements of a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE) ) network, among other examples. The wireless network 100 may include one or more network nodes 110 (shown as a network node 110a, a network node 110b, a network node 110c, and a network node 110d) , a UE 120 or multiple UEs 120 (shown as a UE 120a, a UE 120b, a UE 120c, a UE 120d, and a UE 120e) , and / or other entities. A network node 110 is a network node that communicates with UEs 120. As shown, a network node 110 may include one or more network nodes. For example, a network node 110 may be an aggregated network node, meaning that the aggregated network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit) . As another example, a network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated base station) , meaning that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed among two or more nodes (such as one or more central units (CUs) , one or more distributed units (DUs) , or one or more radio units (RUs) ) .
[0035] In some examples, a network node 110 is or includes a network node that communicates with UEs 120 via a radio access link, such as an RU. In some examples, a network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, a network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or a core network via a backhaul link, such as a CU. In some examples, a network node 110 (such as an aggregated network node 110 or a disaggregated network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. A network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G) , a gNB (e.g., in 5G) , an access point, a transmission reception point (TRP) , a DU, an RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, the network nodes 110 may be interconnected to one another or to one or more other network nodes 110 in the wireless network 100 through various types of fronthaul, midhaul, and / or backhaul interfaces, such as a direct physical connection, an air interface, or a virtual network, using any suitable transport network.
[0036] In some examples, a network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP) , the term “cell” can refer to a coverage area of a network node 110 and / or a network node subsystem serving this coverage area, depending on the context in which the term is used. A network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 120 with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs 120 having association with the femto cell (e.g., UEs 120 in a closed subscriber group (CSG) ) . A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. A network node 110 for a femto cell may be referred to as a femto network node or an in-home network node. In the example shown in Fig. 1, the network node 110a may be a macro network node for a macro cell 102a, the network node 110b may be a pico network node for a pico cell 102b, and the network node 110c may be a femto network node for a femto cell 102c. A network node may support one or multiple (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a network node 110 that is mobile (e.g., a mobile network node) .
[0037] In some aspects, the terms “base station” or “network node” may refer to an aggregated base station, a disaggregated base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, “base station” or “network node” may refer to a CU, a DU, an RU, a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC) , or a Non-Real Time (Non-RT) RIC, or a combination thereof. In some aspects, the terms “base station” or “network node” may refer to one device configured to perform one or more functions, such as those described herein in connection with the network node 110. In some aspects, the terms “base station” or “network node” may refer to a plurality of devices configured to perform the one or more functions. For example, in some distributed systems, each of a quantity of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to duplicate performance of at least a portion of the function, and the terms “base station” or “network node” may refer to any one or more of those different devices. In some aspects, the terms “base station” or “network node” may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the terms “base station” or “network node” may refer to one of the base station functions and not another. In this way, a single device may include more than one base station.
[0038] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive a transmission of data from an upstream node (e.g., a network node 110 or a UE 120) and send a transmission of the data to a downstream node (e.g., a UE 120 or a network node 110) . A relay station may be a UE 120 that can relay transmissions for other UEs 120. In the example shown in Fig. 1, the network node 110d (e.g., a relay network node) may communicate with the network node 110a (e.g., a macro network node) and the UE 120d in order to facilitate communication between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, or the like.
[0039] The wireless network 100 may be a heterogeneous network that includes network nodes 110 of different types, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, or the like. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, macro network nodes may have a high transmit power level (e.g., 5 to 40 watts) whereas pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 to 2 watts) .
[0040] A network controller 130 may couple to or communicate with a set of network nodes 110 and may provide coordination and control for these network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link. In some aspects, the network controller 130 may be a CU or a core network device, or may include a CU or a core network device.
[0041] The UEs 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. A UE 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. A UE 120 may be a cellular phone (e.g., a smart phone) , a personal digital assistant (PDA) , a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet) ) , an entertainment device (e.g., a music device, a video device, and / or a satellite radio) , a vehicular component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and / or any other suitable device that is configured to communicate via a wireless or wired medium.
[0042] Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE and / or an eMTC UE may include, for example, a robot, an unmanned aerial vehicle, a remote device, a sensor, a meter, a monitor, and / or a location tag, that may communicate with a network node, another device (e.g., a remote device) , or some other entity. Some UEs 120 may be considered Internet-of-Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered a Customer Premises Equipment. A UE 120 may be included inside a housing that houses components of the UE 120, such as processor components and / or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.
[0043] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.
[0044] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using a network node 110 as an intermediary to communicate with one another) . For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol) , and / or a mesh network. In such examples, a UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the network node 110.
[0045] Devices of the wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, or the like. For example, devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz –7.125 GHz) and FR2 (24.25 GHz –52.6 GHz) . It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz –300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band.
[0046] The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz –24.25 GHz) . Frequency bands falling within FR3 may inherit FR1 characteristics and / or FR2 characteristics, and thus may effectively extend features of FR1 and / or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz –71 GHz) , FR4 (52.6 GHz –114.25 GHz) , and FR5 (114.25 GHz –300 GHz) . Each of these higher frequency bands falls within the EHF band.
[0047] With the above examples in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges.
[0048] In some aspects, the UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive, from a network node of a radio access network and based at least in part on a data collection configuration from a server, a data collection indication of an occurrence of a configured data collection event; and transmit, toward the server, a data collection report identifying data collected for one or more configured parameters in connection with the configured data collection event. Additionally, or alternatively, the communication manager 140 may perform one or more other operations described herein.
[0049] In some aspects, the network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may receive, from a server, a configuration for a data collection event; transmit, to a UE and based at least in part on the data collection configuration, a data collection indication of an occurrence of a configured data collection event; and receive, from the UE, a data collection report identifying data collected for one or more configured parameters in connection with the configured data collection event. Additionally, or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0050] As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1.
[0051] Fig. 2 is a diagram illustrating an example 200 of a network node 110 in communication with a UE 120 in a wireless network 100, in accordance with the present disclosure. The network node 110 may be equipped with a set of antennas 234a through 234t, such as T antennas (T ≥ 1) . The UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas (R ≥ 1) . The network node 110 of example 200 includes one or more radio frequency components, such as antennas 234 and a modem 232. In some examples, a network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include radio frequency components that facilitate direct communication with the UE 120, such as one or more CUs, or one or more DUs.
[0052] At the network node 110, a transmit processor 220 may receive data, from a data source 212, intended for the UE 120 (or a set of UEs 120) . The transmit processor 220 may select one or more modulation and coding schemes (MCSs) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from that UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS (s) selected for the UE 120 and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI) ) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS) ) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS) ) . A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) , shown as modems 232a through 232t. For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem 232. Each modem 232 may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 may further use a respective modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) , shown as antennas 234a through 234t.
[0053] At the UE 120, a set of antennas 252 (shown as antennas 252a through 252r) may receive the downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) , shown as modems 254a through 254r. For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem 254. Each modem 254 may use a respective demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) a received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modems 254, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to a data sink 260, and may provide decoded control information and system information to a controller / processor 280. The term “controller / processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other examples. In some examples, one or more components of the UE 120 may be included in a housing 284.
[0054] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.
[0055] One or more antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and / or an antenna array may include one or more antenna elements (within a single housing or multiple housings) , a set of coplanar antenna elements, a set of non-coplanar antenna elements, and / or one or more antenna elements coupled to one or more transmission and / or reception components, such as one or more components of Fig. 2.
[0056] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and / or CQI) from the controller / processor 280. The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by the modems 254 (e.g., for DFT-s-OFDM or CP-OFDM) , and transmitted to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of the antenna (s) 252, the modem (s) 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, and / or the TX MIMO processor 266. The transceiver may be used by a processor (e.g., the controller / processor 280) and the memory 282 to perform aspects of any of the methods described herein (e.g., with reference to Figs. 6A-11) .
[0057] At the network node 110, the uplink signals from UE 120 and / or other UEs may be received by the antennas 234, processed by the modem 232 (e.g., a demodulator component, shown as DEMOD, of the modem 232) , detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and provide the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of the antenna (s) 234, the modem (s) 232, the MIMO detector 236, the receive processor 238, the transmit processor 220, and / or the TX MIMO processor 230. The transceiver may be used by a processor (e.g., the controller / processor 240) and the memory 242 to perform aspects of any of the methods described herein (e.g., with reference to Figs. 6A-11) .
[0058] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or any other component (s) of Fig. 2 may perform one or more techniques associated with radio access network (RAN) coordinated UE data management, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or any other component (s) of Fig. 2 may perform or direct operations of, for example, process 800 of Fig. 8, process 900 of Fig. 9, and / or other processes as described herein. The memory 242 and the memory 282 may store data and program codes for the network node 110 and the UE 120, respectively. In some examples, the memory 242 and / or the memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and / or interpreting) by one or more processors of the network node 110 and / or the UE 120, may cause the one or more processors, the UE 120, and / or the network node 110 to perform or direct operations of, for example, process 800 of Fig. 8, process 900 of Fig. 9, and / or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and / or interpreting the instructions, among other examples.
[0059] In some aspects, the UE 120 includes means for receiving, from a network node of a radio access network and based at least in part on a data collection configuration from a server, a data collection indication of an occurrence of a configured data collection event; and / or means for transmitting, toward the server, a data collection report identifying data collected for one or more configured parameters in connection with the configured data collection event. The means for the UE 120 to perform operations described herein may include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.
[0060] In some aspects, the network node 110 includes means for receiving, from a server, a configuration for a data collection event; means for transmitting, to a UE and based at least in part on the data collection configuration, a data collection indication of an occurrence of a configured data collection event; and / or means for receiving, from the UE, a data collection report identifying data collected for one or more configured parameters in connection with the configured data collection event. The means for the network node 110 to perform operations described herein may include, for example, one or more of communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.
[0061] In some aspects, an individual processor may perform all of the functions described as being performed by the one or more processors. In some aspects, one or more processors may collectively perform a set of functions. For example, a first set of (one or more) processors of the one or more processors may perform a first function described as being performed by the one or more processors, and a second set of (one or more) processors of the one or more processors may perform a second function described as being performed by the one or more processors. The first set of processors and the second set of processors may be the same set of processors or may be different sets of processors. Reference to “one or more processors” should be understood to refer to any one or more of the processors described in connection with Fig. 2. Reference to “one or more memories” should be understood to refer to any one or more memories of a corresponding device, such as the memory described in connection with Fig. 2. For example, functions described as being performed by one or more memories can be performed by the same subset of the one or more memories or different subsets of the one or more memories.
[0062] While blocks in Fig. 2 are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.
[0063] As indicated above, Fig. 2 is provided as an example. Other examples may differ from what is described with regard to Fig. 2.
[0064] Deployment of communication systems, such as 5G NR systems, may be arranged in multiple manners with various components or constituent parts. In a 5G NR system, or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station, or a network equipment may be implemented in an aggregated or disaggregated architecture. For example, a base station (such as a Node B (NB) , an evolved NB (eNB) , an NR base station, a 5G NB, an access point (AP) , a TRP, or a cell, among other examples) , or one or more units (or one or more components) performing base station functionality, may be implemented as an aggregated base station (also known as a standalone base station or a monolithic base station) or a disaggregated base station. “Network entity” or “network node” may refer to a disaggregated base station, or to one or more units of a disaggregated base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof) .
[0065] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit) . A disaggregated base station (e.g., a disaggregated network node) may be configured to utilize a protocol stack that is physically or logically distributed among two or more units (such as one or more CUs, one or more DUs, or one or more RUs) . In some examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed throughout one or multiple other network nodes. The DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU also can be implemented as virtual units, such as a virtual central unit (VCU) , a virtual distributed unit (VDU) , or a virtual radio unit (VRU) , among other examples.
[0066] Base station-type operation or network design may consider aggregation characteristics of base station functionality. For example, disaggregated base stations may be utilized in an IAB network, an open radio access network (O-RAN (such as the network configuration sponsored by the O-RAN Alliance) ) , or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN) ) to facilitate scaling of communication systems by separating base station functionality into one or more units that can be individually deployed. A disaggregated base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented for at least one unit virtually, which can enable flexibility in network design. The various units of the disaggregated base station can be configured for wired or wireless communication with at least one other unit of the disaggregated base station.
[0067] Fig. 3 is a diagram illustrating an example disaggregated base station architecture 300, in accordance with the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that can communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control units (such as a Near-RT RIC 325 via an E2 link, or a Non-RT RIC 315 associated with a Service Management and Orchestration (SMO) Framework 305, or both) . A CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as through F1 interfaces. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be simultaneously served by multiple RUs 340.
[0068] Each of the units, including the CUs 310, the DUs 330, the RUs 340, as well as the Near-RT RICs 325, the Non-RT RICs 315, and the SMO Framework 305, may include one or more interfaces or be coupled with one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller providing instructions to one or multiple communication interfaces of the respective unit, can be configured to communicate with one or more of the other units via the transmission medium. In some examples, each of the units can include a wired interface, configured to receive or transmit signals over a wired transmission medium to one or more of the other units, and a wireless interface, which may include a receiver, a transmitter or transceiver (such as an RF transceiver) , configured to receive or transmit signals, or both, over a wireless transmission medium to one or more of the other units.
[0069] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions can include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, among other examples. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (for example, Central Unit –User Plane (CU-UP) functionality) , control plane functionality (for example, Central Unit –Control Plane (CU-CP) functionality) , or a combination thereof. In some implementations, the CU 310 can be logically split into one or more CU-UP units and one or more CU-CP units. A CU-UP unit can communicate bidirectionally with a CU-CP unit via an interface, such as the E1 interface when implemented in an O-RAN configuration. The CU 310 can be implemented to communicate with a DU 330, as necessary, for network control and signaling.
[0070] Each DU 330 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers depending, at least in part, on a functional split, such as a functional split defined by the 3GPP. In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, among other examples. In some aspects, the DU 330 may further host one or more low PHY layers, such as implemented by one or more modules for a fast Fourier transform (FFT) , an inverse FFT (iFFT) , digital beamforming, or physical random access channel (PRACH) extraction and filtering, among other examples. Each layer (which also may be referred to as a module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 330, or with the control functions hosted by the CU 310.
[0071] Each RU 340 may implement lower-layer functionality. In some deployments, an RU 340, controlled by a DU 330, may correspond to a logical node that hosts RF processing functions or low-PHY layer functions, such as performing an FFT, performing an iFFT, digital beamforming, or PRACH extraction and filtering, among other examples, based on a functional split (for example, a functional split defined by the 3GPP) , such as a lower layer functional split. In such an architecture, each RU 340 can be operated to handle over the air (OTA) communication with one or more UEs 120. In some implementations, real-time and non-real-time aspects of control and user plane communication with the RU (s) 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration can enable each DU 330 and the CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.
[0072] The SMO Framework 305 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operations and maintenance interface (such as an O1 interface) . For virtualized network elements, the SMO Framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface (such as an O2 interface) . Such virtualized network elements can include, but are not limited to, CUs 310, DUs 330, RUs 340, non-RT RICs 315, and Near-RT RICs 325. In some implementations, the SMO Framework 305 can communicate with a hardware aspect of a 4G RAN, such as an open eNB (O-eNB) 311, via an O1 interface. Additionally, in some implementations, the SMO Framework 305 can communicate directly with each of one or more RUs 340 via a respective O1 interface. The SMO Framework 305 also may include a Non-RT RIC 315 configured to support functionality of the SMO Framework 305.
[0073] The Non-RT RIC 315 may be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, Artificial Intelligence / Machine Learning (AI / ML) workflows including model training and updates, or policy-based guidance of applications / features in the Near-RT RIC 325. The Non-RT RIC 315 may be coupled to or communicate with (such as via an A1 interface) the Near-RT RIC 325. The Near-RT RIC 325 may be configured to include a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions over an interface (such as via an E2 interface) connecting one or more CUs 310, one or more DUs 330, or both, as well as an O-eNB, with the Near-RT RIC 325.
[0074] In some implementations, to generate AI / ML models to be deployed in the Near-RT RIC 325, the Non-RT RIC 315 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 325 and may be received at the SMO Framework 305 or the Non-RT RIC 315 from non-network data sources or from network functions. In some examples, the Non-RT RIC 315 or the Near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the Non-RT RIC 315 may monitor long-term trends and patterns for performance and employ AI / ML models to perform corrective actions through the SMO Framework 305 (such as reconfiguration via an O1 interface) or via creation of RAN management policies (such as A1 interface policies) .
[0075] As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with regard to Fig. 3.
[0076] Fig. 4 is a diagram illustrating an example architecture 400 of a functional framework for RAN intelligence enabled by data collection, in accordance with the present disclosure. In some scenarios, the functional framework for RAN intelligence may be enabled by further enhancement of data collection through use cases and / or examples. For example, principles or algorithms for RAN intelligence enabled by AI / ML and the associated functional framework (e.g., the AI functionality and / or the input / output of the component for AI enabled optimization) have been utilized or studied to identify the benefits of AI enabled RAN through possible use cases (e.g., beam management, energy saving, load balancing, mobility management, and / or coverage optimization, among other examples) . In one example, as shown by the architecture 400, a functional framework for RAN intelligence may include multiple logical entities, such as a model training host 402, a model inference host 404, data sources 406, and an actor 408.
[0077] The model inference host 404 may be configured to run an AI / ML model based on inference data provided by the data sources 406, and the model inference host 404 may produce an output (e.g., a prediction) with the inference data input to the actor 408. The actor 408 may be an element or an entity of a core network or a RAN. For example, the actor 408 may be a UE, a network node, base station (e.g., a gNB) , a CU, a DU, and / or an RU, among other examples. In addition, the actor 408 may also depend on the type of tasks performed by the model inference host 404, type of inference data provided to the model inference host 404, and / or type of output produced by the model inference host 404. For example, if the output from the model inference host 404 is associated with position determination, the actor 408 may be a UE, a DU or an RU. In some examples, the model inference host 404 may be hosted on the actor 408. For example, a UE may be the actor 408 and may host the model inference host 404. In some aspects, a UE (e.g., the actor 408) may be a data source 406. For example, the UE may perform a measurement (e.g., an NR measurement) , may input the measurement to the AI / ML model at the model inference host 404 (or may provide the measurement to the model inference host 404) , and may act based on an output of the AI / ML model (e.g., positioning information) .
[0078] After the actor 408 receives an output from the model inference host 404, the actor 408 may determine whether to act based on the output. For example, if the actor 408 is a UE and the output from the model inference host 404 is associated with position information, the actor 408 may determine whether to report the position information, reconfigure a beam, or the like. If the actor 408 determines to act based on the output, in some examples, the actor 408 may indicate the action to at least one subject of action 410.
[0079] The data sources 406 may also be configured for collecting data that is used as training data for training an ML model or as inference data for feeding an ML model inference operation. For example, the data sources 406 may collect data from one or more core network and / or RAN entities, which may include the actor 408 or the subject of action 410, and provide the collected data to the model training host 402 for ML model training. In some aspects, the model training host 402 may be co-located with the model inference host 404 and / or the actor 408. For example, the actor 408 or the subject of action 410 may provide performance feedback associated with the beam configuration to the data sources 406, where the performance feedback may be used by the model training host 402 for monitoring or evaluating the ML model performance, such as whether the output (e.g., prediction) provided to the actor 408 is accurate. In some examples, the model training host 402 may monitor or evaluate ML model performance using a training position value, which may be provided by a node (e.g., a UE 120 or a network node 110) , as described elsewhere herein. In some examples, if the output provided by the actor 408 is inaccurate (or the accuracy is below an accuracy threshold) , then the model training host 402 may determine to modify or retrain the ML model used by the model inference host, such as via an ML model deployment / update.
[0080] As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with regard to Fig. 4.
[0081] Fig. 5 is a diagram illustrating an example 500 of data collection by a UE, in accordance with the present disclosure. As shown in Fig. 5, example 500 may include a UE 120 (e.g., that is operating an application client) , a 5G network data analytics function (NWDAF) 502, a data collection application function (DCAF) 504, a network exposure function (NEF) 506, and an application server 508.
[0082] As further shown in Fig. 5, and by reference number 550, the application server 508 may transmit configuration information to the DCAF 504. For example, the application server 508 may transmit a measurement configuration indicating a set of measurements that the UE 120 is to perform. As shown by reference number 552, the application server 508 may transmit configuration information to the UE 120. For example, the application server 508 may transmit a measurement configuration indicating a set of measurements that the UE 120 is to perform.
[0083] As further shown in Fig. 5, and by reference number 554, the NWDAF 502 may perform a consent verification procedure. For example, the NWDAF 502 may perform a procedure to determine whether the UE 120 consents to performing one or more measurements on behalf of the application server 508. As shown by reference number 556, based on completing the consent procedure, the NWDAF 502 may transmit an event exposure subscribe message to the DCAF 504. In this case, the NWDAF 502 subscribes to event notifications from the DCAF 504, such as event notifications relating to data collection and reporting. As shown by reference number 558, the UE 120 may perform data collection and may transmit a data collection report to the DCAF 504 (e.g., via user plane function (UPF) signaling) . In this case, the data collection is triggered by the application server 508 and / or autonomously at the UE 120. Accordingly, a RAN device, such as a network node, cannot trigger UE data collection and / or configure UE data collection. For beam management, for example, a performance of an AI / ML model may be based at least in part on a codebook index that is used. However, the codebook index that is used is selected at the RAN level, rather than the application server level. Based on receiving the data collection report, the DCAF 504 notifies the NWDAF 502 by transmitting an event exposure notification message, as shown by reference number 560.
[0084] As indicated above, Fig. 5 is provided as an example. Other examples may differ from what is described with respect to Fig. 5.
[0085] Some aspects described herein enable RAN coordinated UE data management. For example, a network node may use signaling to receive a data collection configuration from a server (e.g., an application server) and deploy the data collection configuration to a UE. When a data collection event occurs, the network node may transmit signaling to cause the UE to collect data regarding a network and transmit a data collection report to the network node and / or the server. Additionally, or alternatively, the network node may configure the UE to autonomously detect an occurrence of a data collection event, initiate data collection, and transmit a data collection report. In this way, the UE can collect data in accordance with a RAN configuration or condition, which may enable improved model training and / or deployment relative to data collection that occurs without RAN involvement, as described in more detail herein.
[0086] Figs. 6A-6D are diagrams illustrating examples 600-A through 600-D associated with RAN coordinated UE data management, in accordance with the present disclosure. As shown in Figs. 6A-6D, examples 600-A through 600-D include communication between a UE 120, a network node 110, a 5G core access and mobility management function (AMF) 602, a DCAF 604, and an operation and maintenance (OAM) service management and orchestration component (OAM / SMO) 606 (e.g., a server, such as an application server) .
[0087] As further shown in Fig. 6A, example 600-A shows signaling to enable the OAM / SMO 606 to pre-configure a RAN (e.g., the network node 110) with a set of event definitions, using non-UE-specific signaling, and to enable the DCAF 604 to configure data collection with the RAN using UE-specific signaling. As shown by reference number 620, the UE 120 may receive configuration information from the OAM / SMO 606. For example, the OAM / SMO 606 may configure an application client of the UE 120 with an event identifier list. The event identifier list may specify a set of events for which data collection is to occur.
[0088] As further shown in Fig. 6A, and by reference number 622, the DCAF 604 and the OAM / SMO 606 may perform a data collection event negotiation procedure. For example, the DCAF 604 and the OAM / SMO 606 may exchange signaling to enable the OAM / SMO 606 to define a set of events (e.g., data collection events with which the DCAF 604 is not already configured) . Additionally, or alternatively, the DCAF 604 and the OAM / SMO 606 may exchange signaling to identify a set of areas in which events can be activated, such as a set of cells, a set of geographic areas, a set of UE groups, or another granularity for event activation.
[0089] As further shown in Fig. 6A, and by reference number 624, the network node 110 may receive a configuration for data collection. For example, the network node 110 may receive an event exposure (EVEX) event definition configuration message that includes a set of parameters, such as an event identifier list or a set of definitions of a set of events. In this way, the network node 110 is configured to have configuration information corresponding to the data collection configuration information provided to the UE 120, thereby enabling the network node 110 to synchronize with the UE 120 and / or configure the UE 120, as described herein. In some aspects, the network node 110 may receive the data collection configuration for data collection via non-UE-specific signaling. For example, the network node 110 may receive the data collection configuration via group signaling common to a set of UEs (e.g., operating on the network node 110) .
[0090] As further shown in Fig. 6A, and by reference numbers 626-632, the network node 110, AMF 602, and DCAF 604 may communicate to setup an EVEX trace associated with data collection from the UE 120. For example, the DCAF 604 may transmit a trace activation configuration message, such as via a create data collection context request (reference number 626) . The create data collection context request may include a set of UE identifiers (e.g., identifying the UE 120 among other UEs) , a trace identifier, or a configuration (e.g., an event identifier to configure events if events have not been pre-configured or a data collection profile, which may include a periodicity value or trigger condition associated with data collection) , among other examples. In some aspects, the DCAF 604 may indicate a grouping of one or more events for data collection. For example, the DCAF 604 may provide a list of event groups for which data collection can be performed (e.g., by the UE 120) collectively for model training. In some aspects, the create data collection context request is non-UE-specific signaling. The AMF 602 may initiate an EVEX-specific trace using UE-specific signaling, which may include an event identifier list. For example, the AMF 602 may transmit an EVEX trace activation message to the network node 110 (reference number 628) and may receive an EVEX trace response message (reference number 630) . The EVEX trace activation message may include initial UE context setup information or UE context modification information. Based on receiving the EVEX trace activation response, the AMF 602 may transmit a create data collection context response message to the DCAF 604 to complete setup of the EVEX trace associated with data collection from the UE 120 (reference number 632.
[0091] As further shown in Fig. 6A, and by reference number 634, the network node 110 may communicate with the UE 120 to perform data collection. For example, the network node 110 may transmit a data collection indication, which may indicate an occurrence of an event for which data collection is configured, and may receive a data collection report identifying a set of metrics determined by the UE 120 (e.g., by performing data collection and / or monitoring a channel or cell) . In some aspects, the network node 110 may forward the data collection report to the DCAF 604 (e.g., in connection with the establishment of the EVEX trace) . In some aspects, when a UE 120 is in an idle state or an inactive state when a data collection event occurs, the DCAF 604 may use a paging message to communicate with the UE 120 and cause transmission of a data collection report toward the DCAF 604.
[0092] As shown in Fig. 6B, example 600-B shows signaling to enable the OAM / SMO 606 to pre-configure a RAN (e.g., the network node 110) for EVEX events using UE-specific signaling. Here, based on configuration of the UE 120 (reference number 620) , data collection event negotiation (reference number 622) , and EVEX event definition configuration (reference number 624) , and as shown by reference number 636, the DCAF 604 transmits a trace activation request to the OAM / SMO 606. In this case, the OAM / SMO 606 provides a service for an entity (e.g., the DCAF 604) to request trace activations. The DCAF 604 may include a UE identifier (e.g., of the UE 120) and / or an event identifier (e.g., of an event for which the DCAF 604 is registering a trace to receive a data collection report) in the trace activation request message. The OAM / SMO 606 transmits an EVEX trace activation configuration, as shown by reference number 638, that includes one or more UE identifiers, a trace identifier, a configuration (e.g., which may include an event identifier or a data collection profile) . The AMF 602 transmits an EVEX trace activation (e.g., including an event identifier list) to the network node 110 (reference number 628) and receives an EVEX trace activation response (reference number 630) . Based on the EVEX trace activation response, the AMF 602 forwards the trace activation response to the OAM / SMO 606, as shown by reference number 640, and the OAM / SMO 606 forwards the trace activation response to the DCAF 604, as shown by reference number 642. In this way, the OAM / SMO 606 facilitates establishment of the trace. Based on establishment of the trace, the network node 110 and the UE 120 can communicate to perform data collection and to provide a data collection report to the DCAF 604 (e.g., via the established trace) (reference number 634) .
[0093] As shown in Fig. 6C, example 600-C shows signaling to enable the OAM / SMO 606 to pre-configure a RAN (e.g., the network node 110) for EVEX events using non-UE-specific signaling. Here, based on configuration of the UE 120 (reference number 620) , data collection event negotiation (reference number 622) , EVEX event definition configuration (reference number 624) , and a trace activation request (reference number 636) , the OAM / SMO 606 may transmit an EVEX trace activation configuration to the network node 110 (reference number 638) . The EVEX trace activation configuration may include information identifying a trace identifier, a configuration identifier, an event identifier list, a set of definitions of a set of events, or a data collection profile, among other examples. Based on transmitting the EVEX trace activation configuration, the OAM / SMO 606 may transmit a trace activation response, as shown by reference number 642. In other words, the OAM / SMO 606 may obviate a need for one or more signals between the AMF 602 and the network node 110 by transmitting non-UE-specific signaling to the network node 110 to configure a trace for data collection. Based on configuring the trace for data collection, the network node and the UE 120 can communicate to perform data collection and to provide a data collection report to the DCAF 604 (e.g., via the established trace) (reference number 634) .
[0094] As shown in Fig. 6D, example 600-D shows signaling to report collected data. Here, as shown by reference number 650, the UE 120 may transmit a data availability indication to the network node 110. For example, the UE 120 may indicate that EVEX data has been collected (or can be collected) in connection with an EVEX configuration. In some aspects, the UE 120 may transmit the data availability indication to determine whether the UE 120 is instructed to perform data collection (e.g., to determine a channel condition) . As shown by reference number 652, the network node 110 may transmit a data report indication. For example, the network node 110 may transmit an instruction that the UE 120 is to transmit a data collection report to the DCAF 604. Additionally, or alternatively, the network node 110 may transmit a rejection message indicating that data collection is not to be performed in connection with, for example, a current channel condition. As shown by reference number 654, the UE 120 may perform data collection and transmit a data collection report to the DCAF 604 based at least in part on receiving the EVEX data report indication. For example, the UE 120 may transmit a data collection report including a set of measurements (e.g., EVEX data) , a set of DCAF event identifiers, a set of RAN event identifiers, or a set of event definitions (e.g., based at least in part on a data collection configuration from an SMO / OAM) , among other examples. As shown by reference number 656, the network node 110 may transmit a RAN indication associated with the data collection. For example, based on transmitting the EVEX data report indication to the UE 120, the network node 110 may transmit the RAN indication to the DCAF 604 to indicate a RAN configuration, a set of DCAF identifiers, or a set of RAN identifiers, among other examples associated with the data collection that the UE 120 is performing.
[0095] As indicated above, Fig. 6A-6D are provided as examples. Other examples may differ from what is described with respect to Fig. 6A-6D.
[0096] Fig. 7A-7C are diagrams illustrating examples 700-A through 700-C associated with RAN coordinated UE data management, in accordance with the present disclosure. As shown in Fig. 7A-7C, examples 700-A through 700-C include communication between a network node 110 and a UE 120.
[0097] As shown in Fig. 7A, example 700-A shows signaling for configuration and indication of EVEX data collection between a network node and a UE. Here, as shown by reference number 720, the network node 110 may perform a selection procedure. For example, the network node 110 may select a UE 120 for data collection. Additionally, or alternatively, the network node 110 may select one or more events with which data collection is to be associated (e.g., an event that triggers data collection) . In some aspects, the network node 110 may select one or more event identifiers for one or more UEs 120 based on a configuration received from, for example, an application server, as described above.
[0098] As further shown in Fig. 7A, and by reference number 722, the network node 110 may transmit EVEX data collection configuration information. For example, the network node 110 may transmit configuration information conveying a DCAF event identifier, an application server event identifier, or another event identifier to indicate an event that is to trigger data collection (e.g., as configured by the application server) . Additionally, or alternatively, the network node 110 may transmit configuration information conveying a RAN event identifier or an OAM / SMO event identifier of an event that is to trigger data collection (e.g., as configured by the RAN) . In some aspects, the network node 110 may transmit configuration information defining an event. In other words, the network node 110 may transmit an identifier of an already configured event (e.g., an index value to indicate an event stored in a table) or information configuring an event directly (e.g., an identification of an occurrence of, for example, a message or state change that is to trigger data collection) .
[0099] In some aspects, the network node 110 may transmit a data collection indication of an event occurring at the network node 110. For example, the network node 110 may configure data collection that is to occur when the network node 110 transmits an activation message with a particular event identifier corresponding to an event detected at the network node 110. Additionally, or alternatively, the network node 110 may configure data collection that is to occur when the UE 120 detects an event. For example, the network node 110 may configure the UE 120 to autonomously detect an event, perform data collection, and transmit a data collection report. In some aspects, the network node 110 may transmit information identifying a conditional configuration. For example, the network node 110 may transmit information indicating a combination of events for which data collection is to be performed (e.g., and a configuration of what data collection to perform for an occurrence of the combination of events) .
[0100] Additionally, or alternatively, the network node 110 may transmit configuration information identifying a periodicity or another characteristic of data collection. For example, the network node 110 may instruct the UE 120 that when the UE 120 receives an indication to perform data collection, the UE 120 is to perform the data collection with a configured periodicity. In some aspects, the network node 110 may convey the data collection configuration information via a particular set of signals. For example, the network node 110 may transmit a radio resource control (RRC) configuration, reconfiguration, setup, resume, or release message, among other examples, to convey configuration information to a UE 120 (e.g., which may be in an active, idle, or inactive state among other examples) .
[0101] As further shown in Fig. 7A, and by reference number 724, the network node 110 may detect an event. For example, the network node 110 may determine that an event has occurred for which a UE 120 is configured to perform data collection. In this case, as shown by reference number 726, the network node 110 may transmit an activation indication or message, which may convey a DCAF event identifier, a RAN event identifier, an OAM / SMO event identifier, or another event identifier to indicate which event, for which the UE 120 is configured to perform data collection, has occurred. The network node 110 may use, when the UE 120 is in, for example, an RRC connected mode, RRC signaling, medium access control (MAC) control element (CE) signaling, or system information signaling (e.g., broadcast signaling or on-demand signaling) , among other examples, to convey the activation message. Additionally, or alternatively, when the UE 120 is in an RRC idle or inactive mode, the network node 110 may use RAN or core network (CN) paging or system information signaling to convey the activation message to the UE 120. When the network node 110 transmits a paging message to convey the activation message, the network node 110 may include a flag or indicator in the paging to indicate that the paging is for an activation message. Similarly, when the network node 110 transmits system information, the network node 110 may include an event identifier in the system information, and any UE 120 that receives the system information may determine whether that UE 120 is configured with the included event identifier to determine whether the system information is conveying an activation message for that UE 120.
[0102] As further shown in Fig. 7A, and by reference number 728, based on receiving the activation message, the UE 120 may initiate data collection for the identified event (e.g., and may perform data collection using a configuration specific to the identified event) . In contrast, as shown in Fig. 7B, and by example 700-B, the UE 120 may detect an occurrence of an event directly and start collecting data without activation signaling from the network node 110. In another example, as shown by Fig. 7C, and by example 700-C, the network node 110 may detect an event and may transmit system information triggering data collection, as shown by reference number 740. In other words, rather than pre-configure the UE 120 for data collection and transmit an activation message (or configure the UE 120 to detect an event) , and without an indication of a UE identifier from an AMF, the network node 110 may detect an event and configure the UE 120 for data collection based at least in part on detecting the event. In this case, the network node 110 may transmit, for example, a broadcast system information message conveying a DCAF event identifier, a RAN event identifier, a periodicity, or one or more further triggering events, among other examples. As shown by reference number 742, when the UE 120 (or a set of UEs 120) is configured with a DCAF event identifier matching the event identifier conveyed in the system information message, the UE 120 may start performing data collection in accordance with the system information.
[0103] Returning to Fig. 7A, after a period of time, the network node 110 may transmit deactivation signaling, as shown by reference number 730, to convey a deactivation message that ends data collection. The network node 110 may transmit the deactivation message after expiration of a configured period of time or after detection of another event (e.g., the end of the event for which data collection was triggered) . The network node 110 may transmit the deactivation message via RRC, MAC CE, system information, or paging signaling, as described above.
[0104] As indicated above, Fig. 7A-7C are provided as examples. Other examples may differ from what is described with respect to Fig. 7A-7C.
[0105] Fig. 8 is a diagram illustrating an example process 800 performed, for example, at a UE or an apparatus of a UE, in accordance with the present disclosure. Example process 800 is an example where the apparatus or the UE (e.g., UE 120) performs operations associated with RAN coordinated UE data management.
[0106] As shown in Fig. 8, in some aspects, process 800 may include receiving, from a network node of a radio access network and based at least in part on a data collection configuration from a server, a data collection indication of an occurrence of a configured data collection event (block 810) . For example, the UE (e.g., using reception component 1002 and / or communication manager 1006, depicted in Fig. 10) may receive, from a network node of a radio access network and based at least in part on a data collection configuration from a server, a data collection indication of an occurrence of a configured data collection event, as described above in Figs, 6A-7C and with regard to reference number 620, for example.
[0107] As further shown in Fig. 8, in some aspects, process 800 may include transmitting, toward the server, a data collection report identifying data collected for one or more configured parameters in connection with the configured data collection event (block 820) . For example, the UE (e.g., using transmission component 1004 and / or communication manager 1006, depicted in Fig. 10) may transmit, toward the server, a data collection report identifying data collected for one or more configured parameters in connection with the configured data collection event, as described above in Figs. 6A-7C and with regard to reference numbers 634 and 654, among other examples.
[0108] Process 800 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in connection with one or more other processes described elsewhere herein.
[0109] In a first aspect, the data collection configuration is received via at least one of a radio resource control message, a MAC CE, a system information message, or a paging message.
[0110] In a second aspect, alone or in combination with the first aspect, the data collection configuration is received based at least in part on the occurrence of the configured data collection event, or the data collection configuration information is received prior to the occurrence of the configured data collection event to configure monitoring for the configured data collection event.

[0112] In a fourth aspect, alone or in combination with one or more of the first through third aspects, process 800 includes receiving the data collection indication of the occurrence of the configured data collection event to activate data collection for an event based at least in part on receiving configuration information associated with configuring data collection for one or more configured parameters.
[0113] In a fifth aspect, alone or in combination with one or more of the first through fourth aspects, process 800 includes receiving deactivation signaling, and ending data collection for the occurrence of the configured data collection event based at least in part on receiving the deactivation signaling.
[0114] In a sixth aspect, alone or in combination with one or more of the first through fifth aspects, process 800 includes transmitting availability signaling indicating an availability of data collected in connection with the data collection configuration information or a capability of collecting data, and receiving, based at least in part on transmitting the availability signaling, a request for data collection, wherein transmitting the data collection report comprises transmitting the data collection report based at least in part on receiving the request for data collection.
[0115] In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, the data collection configuration is associated with a UE context of the UE.
[0116] Although Fig. 8 shows example blocks of process 800, in some aspects, process 800 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in Fig. 8. Additionally, or alternatively, two or more of the blocks of process 800 may be performed in parallel.
[0117] Fig. 9 is a diagram illustrating an example process 900 performed, for example, at a network node or an apparatus of a network node, in accordance with the present disclosure. Example process 900 is an example where the apparatus or the network node (e.g., network node 110) performs operations associated with RAN coordinated UE data management.
[0118] As shown in Fig. 9, in some aspects, process 900 may include receiving, from a server, a configuration for a data collection event (block 910) .

[0119] As further shown in Fig. 9, in some aspects, process 900 may include transmitting, to a UE and based at least in part on the data collection configuration, a data collection indication of an occurrence of a configured data collection event (block 920) . For example, the network node (e.g., using transmission component 1104 and / or communication manager 1106, depicted in Fig. 11) may transmit, to a UE and based at least in part on the data collection configuration, a data collection indication of an occurrence of a configured data collection event, as described above in Figs. 6A-7C and with regard to reference number 620, for example.
[0120] As further shown in Fig. 9, in some aspects, process 900 may include receiving, from the UE, a data collection report identifying data collected for one or more configured parameters in connection with the configured data collection event (block 930) . For example, the network node (e.g., using reception component 1102 and / or communication manager 1106, depicted in Fig. 11) may receive, from the UE, a data collection report identifying data collected for one or more configured parameters in connection with the configured data collection event, as described above in Figs. 6A-7C and with regard to reference numbers 634 and 654, for example.
[0121] Process 900 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in connection with one or more other processes described elsewhere herein.
[0122] In a first aspect, the data collection configuration is transmitted via at least one of a radio resource control message, a MAC control element, a system information message, or a paging message.
[0123] In a second aspect, alone or in combination with the first aspect, the data collection configuration is transmitted based at least in part on the occurrence of the configured data collection event, or the data collection configuration information is received prior to the occurrence of the configured data collection event to configure monitoring for the configured data collection event.

[0128] In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, the data collection configuration is associated with a UE context of the UE.
[0129] Although Fig. 9 shows example blocks of process 900, in some aspects, process 900 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in Fig. 9. Additionally, or alternatively, two or more of the blocks of process 900 may be performed in parallel.
[0130] Fig. 10 is a diagram of an example apparatus 1000 for wireless communication, in accordance with the present disclosure. The apparatus 1000 may be a UE, or a UE may include the apparatus 1000. In some aspects, the apparatus 1000 includes a reception component 1002, a transmission component 1004, and / or a communication manager 1006, which may be in communication with one another (for example, via one or more buses and / or one or more other components) . In some aspects, the communication manager 1006 is the communication manager 140 described in connection with Fig. 1. As shown, the apparatus 1000 may communicate with another apparatus 1008, such as a UE or a network node (such as a CU, a DU, an RU, or a base station) , using the reception component 1002 and the transmission component 1004.
[0131] In some aspects, the apparatus 1000 may be configured to perform one or more operations described herein in connection with Figs. 6A-7C. Additionally, or alternatively, the apparatus 1000 may be configured to perform one or more processes described herein, such as process 800 of Fig. 8. In some aspects, the apparatus 1000 and / or one or more components shown in Fig. 10 may include one or more components of the UE described in connection with Fig. 2. Additionally, or alternatively, one or more components shown in Fig. 10 may be implemented within one or more components described in connection with Fig. 2. Additionally, or alternatively, one or more components of the set of components may be implemented at least in part as software stored in one or more memories. For example, a component (or a portion of a component) may be implemented as instructions or code stored in a non-transitory computer-readable medium and executable by one or more controllers or one or more processors to perform the functions or operations of the component.
[0132] The reception component 1002 may receive communications, such as reference signals, control information, data communications, or a combination thereof, from the apparatus 1008. The reception component 1002 may provide received communications to one or more other components of the apparatus 1000. In some aspects, the reception component 1002 may perform signal processing on the received communications (such as filtering, amplification, demodulation, analog-to-digital conversion, demultiplexing, deinterleaving, de-mapping, equalization, interference cancellation, or decoding, among other examples) , and may provide the processed signals to the one or more other components of the apparatus 1000. In some aspects, the reception component 1002 may include one or more antennas, one or more modems, one or more demodulators, one or more MIMO detectors, one or more receive processors, one or more controllers / processors, one or more memories, or a combination thereof, of the UE described in connection with Fig. 2.

In some aspects, one or more other components of the apparatus 1000 may generate communications and may provide the generated communications to the transmission component 1004 for transmission to the apparatus 1008. In some aspects, the transmission component 1004 may perform signal processing on the generated communications (such as filtering, amplification, modulation, digital-to-analog conversion, multiplexing, interleaving, mapping, or encoding, among other examples) , and may transmit the processed signals to the apparatus 1008. In some aspects, the transmission component 1004 may include one or more antennas, one or more modems, one or more modulators, one or more transmit MIMO processors, one or more transmit processors, one or more controllers / processors, one or more memories, or a combination thereof, of the UE described in connection with Fig. 2.
