Description

Energy information management method and device in a wireless communication system

[0001] The present invention relates to wireless communication, and more particularly, to a method and device for managing energy information in a wireless communication system.

[0002] 3GPP (3rd Generation Partnership Project) LTE (Long-Term Evolution) is a technology designed to enable high-speed packet communications. Numerous approaches have been proposed to achieve LTE's goals of reducing costs for users and operators, improving service quality, expanding coverage, and increasing system capacity. 3GPP LTE's high-level requirements include reduced cost per bit, improved service availability, flexible use of frequency bands, a simple architecture, open interfaces, and adequate power consumption for terminals.

[0003] The International Telecommunication Union (ITU) and 3GPP have begun work on developing requirements and specifications for New Radio (NR) systems. 3GPP must identify and develop the technical components necessary to successfully standardize NR, meeting both urgent market needs and the longer-term requirements outlined by the ITU Radio Communication Sector (ITU-R) International Mobile Telecommunications (IMT)-2020 process. Furthermore, NR must be able to utilize any spectrum band up to at least 100 GHz, ensuring that it remains available for wireless communications well into the future.

[0004] NR aims to be a single technology framework that addresses all deployment scenarios, usage scenarios, and requirements, including enhanced Mobile BroadBand (eMBB), massive Machine Type Communications (mMTC), and Ultra-Reliable and Low Latency Communications (URLLC). NR must be inherently forward-compatible.

[0053] For convenience of explanation, the implementation of this specification is primarily described in relation to a 3GPP-based wireless communication system. However, the technical features of this specification are not limited thereto. For example, the following detailed description is provided based on a mobile communication system corresponding to a 3GPP-based wireless communication system. However, aspects of this specification that are not limited to a 3GPP-based wireless communication system can be applied to other mobile communication systems.

[0054] Figure 1 illustrates an example of a communication system to which the implementation of this specification is applied.

[0055] The 5G usage scenario shown in FIG. 1 is only an example, and the technical features of this specification can be applied to other 5G usage scenarios not shown in FIG. 1.

[0056] The three main requirement categories for 5G are (1) enhanced mobile broadband (eMBB), (2) massive machine type communication (mMTC), and (3) ultra-reliable and low latency communications (URLLC).

[0057] Referring to FIG. 1, a communication system (1) includes wireless devices (100a to 100f), a base station (BS; 200), and a network (300). FIG. 1 illustrates a 5G network as an example of a network of the communication system (1), but the implementation of the present disclosure is not limited to a 5G system and can be applied to future communication systems beyond the 5G system.

[0058] The base station (200) and the network (300) may be implemented as wireless devices, and a particular wireless device may operate as a base station / network node in relation to other wireless devices.

[0059] The wireless devices (100a to 100f) represent devices that perform communication using Radio Access Technology (RAT) (e.g., 5G NR or LTE) and may also be referred to as communication / wireless / 5G devices. The wireless devices (100a to 100f) may include, but are not limited to, a robot (100a), a vehicle (100b-1 and 100b-2), an extended reality (XR) device (100c), a portable device (100d), a home appliance (100e), an Internet-of-Things (IoT) device (100f), and an artificial intelligence (AI) device / server (400). For example, the vehicles may include vehicles having wireless communication capabilities, autonomous vehicles, and vehicles capable of performing vehicle-to-vehicle communication. The vehicles may include unmanned aerial vehicles (UAVs) (e.g., drones). XR devices may include AR (Augmented Reality) / VR (Virtual Reality) / MR (Mixed Reality) devices, and may be implemented in the form of HMD (Head-Mounted Device) and HUD (Head-Up Display) mounted on vehicles, televisions, smartphones, computers, wearable devices, home appliances, digital signs, vehicles, robots, etc. Portable devices may include smartphones, smart pads, wearable devices (e.g., smart watches or smart glasses), and computers (e.g., laptops). Home appliances may include TVs, refrigerators, and washing machines. IoT devices may include sensors and smart meters.

[0060] In this specification, wireless devices (100a to 100f) may be referred to as user equipment (UE). The UE may include, for example, a mobile phone, a smartphone, a laptop computer, a digital broadcasting terminal, a personal digital assistant (PDA), a portable multimedia player (PMP), a navigation system, a slate PC, a tablet PC, an ultrabook, a vehicle, a vehicle with autonomous driving function, a connected car, a UAV, an AI module, a robot, an AR device, a VR device, an MR device, a hologram device, a public safety device, an MTC device, an IoT device, a medical device, a fintech device (or a financial device), a security device, a weather / environmental device, a 5G service-related device, or a 4th industrial revolution-related device.

[0061] For example, a UAV may be an aircraft that is unmanned and navigated by radio control signals.

[0062] For example, a VR device may include a device for implementing objects or backgrounds in a virtual environment. For example, an AR device may include a device that implements objects or backgrounds in a virtual world by connecting them to objects or backgrounds in the real world. For example, an MR device may include a device that implements objects or backgrounds in a virtual world by merging them with objects or backgrounds in the real world. For example, a holographic device may include a device that implements 360-degree stereoscopic images by recording and reproducing three-dimensional information using the light interference phenomenon that occurs when two laser lights, called holograms, meet.

[0063] For example, a public safety device may include an image relay device or imaging device that can be worn on the user's body.

[0065] For example, a medical device may be a device used for the purpose of diagnosing, treating, mitigating, curing, or preventing a disease. For example, a medical device may be a device used for diagnosing, treating, mitigating, or correcting an injury or damage. For example, a medical device may be a device used for the purpose of examining, replacing, or modifying a structure or function.

[0066] For example, a medical device may be a device used for the purpose of regulating pregnancy. For example, a medical device may include a therapeutic device, a driving device, an (in vitro) diagnostic device, a hearing aid, or a surgical device.

[0069] For example, a weather / environment device may include a device that monitors or predicts the weather / environment.

[0070] Wireless devices (100a to 100f) can be connected to a network (300) via a base station (200). AI technology can be applied to the wireless devices (100a to 100f), and the wireless devices (100a to 100f) can be connected to an AI server (400) via the network (300). The network (300) can be configured using a 3G network, a 4G (e.g., LTE) network, a 5G (e.g., NR) network, and a network after 5G. The wireless devices (100a to 100f) can communicate with each other via the base station (200) / network (300), but can also communicate directly (e.g., sidelink communication) without going through the base station (200) / network (300).

[0071] For example, vehicles (100b-1, 100b-2) can communicate directly (e.g., vehicle-to-vehicle (V2V) / vehicle-to-everything (V2X) communication). Additionally, IoT devices (e.g., sensors) can communicate directly with other IoT devices (e.g., sensors) or other wireless devices (100a to 100f).

[0072] Wireless communication / connection (150a, 150b, 150c) can be established between wireless devices (100a to 100f) and / or between wireless devices (100a to 100f) and a base station (200) and / or between base stations (200). Here, the wireless communication / connection can be established through various RATs (e.g., 5G NR), such as uplink / downlink communication (150a), sidelink communication (150b) (or, D2D (Device-To-Device) communication), and base station-to-base station communication (150c) (e.g., relay, IAB (Integrated Access and Backhaul)). Through the wireless communication / connection (150a, 150b, 150c), the wireless devices (100a to 100f) and the base station (200) can transmit / receive wireless signals to / from each other. For example, wireless communication / connection (150a, 150b, 150c) can transmit / receive signals through various physical channels.

[0073] To this end, at least some of the various configuration information setting processes for transmitting / receiving wireless signals, various signal processing processes (e.g., channel encoding / decoding, modulation / demodulation, resource mapping / demapping, etc.), and resource allocation processes may be performed based on various proposals of this specification.

[0074] AI is the field of study that studies artificial intelligence or the methodologies for creating it, while machine learning defines various problems in the field of artificial intelligence and studies the methodologies for solving them. Machine learning is also defined as an algorithm that improves performance on a task through consistent experience.

[0075] A robot can be defined as a machine that automatically processes or operates a given task based on its own capabilities. Specifically, a robot capable of perceiving its environment, making decisions, and performing actions on its own can be called an intelligent robot. Robots can be categorized into industrial, medical, household, and military applications based on their intended use or field. Robots are equipped with a drive unit, including an actuator or motor, enabling them to perform various physical actions, such as moving robot joints. Furthermore, mobile robots include wheels, brakes, and propellers in their drive unit, enabling them to drive on the ground or fly in the air.

[0076] Autonomous driving refers to the technology of driving on its own, and an autonomous vehicle refers to a vehicle that drives without user intervention or with minimal user intervention.

[0077] For example, autonomous driving can include technologies such as lane keeping, automatic speed control like adaptive cruise control, autonomous driving along a set route, and autonomous driving based on a set destination. Vehicles encompass all types of vehicles, including those with internal combustion engines, hybrid vehicles with both internal combustion engines and electric motors, and electric vehicles with only electric motors. These vehicles can include not only cars but also trains and motorcycles. Autonomous vehicles can be viewed as robots with autonomous driving capabilities.

[0078] Extended reality is a general term for VR, AR, and MR. VR technology provides real-world objects and backgrounds as CG images only, AR technology provides virtual CG images over images of real objects, and MR technology is a CG technology that mixes and combines virtual objects with the real world. MR technology is similar to AR in that it displays real and virtual objects together. However, there is a difference: while AR uses virtual objects to complement real objects, MR uses virtual and real objects equally.

[0079] NR supports multiple numerologies, or subcarrier spacings (SCS), to support diverse 5G services. For example, an SCS of 15 kHz supports wide areas in traditional cellular bands; an SCS of 30 kHz / 60 kHz supports dense urban areas, lower latency, and wider carrier bandwidth; and an SCS of 60 kHz or higher supports bandwidths greater than 24.25 GHz to overcome phase noise.

[0080] The NR frequency band can be defined by two types of frequency ranges (FR1 and FR2). The numerical values ​​of the frequency ranges can be changed. For example, the two types of frequency ranges (FR1 and FR2) can be as shown in Table 1 below. For convenience of explanation, among the frequency ranges used in the NR system, FR1 can mean the "sub 6 GHz range," and FR2 can mean the "above 6 GHz range," which can be called millimeter wave (mmW).

[0081] Frequency Range DefinitionFrequency RangeSubcarrier SpacingFR1450MHz - 6000MHz15, 30, 60 kHzFR224250MHz - 52600MHz60, 120, 240 kHz

[0082]

[0083] As described above, the numerical value of the frequency range of the NR system can be changed. For example, FR1 may include a band from 410 MHz to 7125 MHz, as shown in Table 2 below. That is, FR1 may include frequency bands above 6 GHz (or 5850, 5900, 5925 MHz, etc.). For example, the frequency bands above 6 GHz (or 5850, 5900, 5925 MHz, etc.) included within FR1 may include unlicensed bands. Unlicensed bands may be used for various purposes, such as for vehicular communications (e.g., autonomous driving).

[0084] Frequency Range DefinitionFrequency RangeSubcarrier SpacingFR1410MHz - 7125MHz15, 30, 60 kHzFR224250MHz - 52600MHz60, 120, 240 kHz

[0085]

[0086] Here, the wireless communication technology implemented in the wireless device of the present specification may include not only LTE, NR, and 6G, but also Narrowband IoT (NB-IoT) for low-power communication. For example, NB-IoT technology may be an example of LPWAN (Low Power Wide Area Network) technology and may be implemented with standards such as LTE Cat NB1 and / or LTE Cat NB2, and is not limited to the above-described names. Additionally or alternatively, the wireless communication technology implemented in the wireless device of the present specification may perform communication based on LTE-M technology. For example, LTE-M technology may be an example of LPWAN technology and may be called by various names such as eMTC (enhanced MTC). For example, LTE-M technology can be implemented by at least one of various standards such as 1) LTE CAT 0, 2) LTE Cat M1, 3) LTE Cat M2, 4) LTE non-BL (Non-Bandwidth Limited), 5) LTE-MTC, 6) LTE MTC, and / or 7) LTE M, and is not limited to the above-described names. Additionally or alternatively, the wireless communication technology implemented in the wireless device of the present specification can include at least one of ZigBee, Bluetooth, and / or LPWAN considering low-power communication, and is not limited to the above-described names. For example, ZigBee technology can create PANs (Personal Area Networks) related to small / low-power digital communication based on various standards such as IEEE 802.15.4, and can be called by various names.

[0153] Figure 5 illustrates the 5G system architecture for a non-roaming case using a reference point representation showing how various network functions interact with each other.

[0154] In Figure 5, for clarity of the point-to-point diagram, UDSF, NEF, and NRF are not illustrated. However, all network functions shown can interact with UDSF, UDR, NEF, and NRF as needed.

[0155] For clarity, the connection between UDR and other NFs (e.g., PCF) is not shown in Fig. 5. For clarity, the connection between NWDAF and other NFs (e.g., PCF) is not shown in Fig. 5.

[0156] The 5G system architecture includes the following benchmarks:

[0157] - N1: Reference point between UE and AMF.

[0158] - N2: Reference point between (R)AN and AMF.

[0159] - N3: Reference point between (R)AN and UPF.

[0160] - N4: Reference point between SMF and UPF.

[0174] - N22: Reference point between AMF and NSSF.

[0175] In some cases, two NFs may need to be interconnected to serve a UE.

[0176] Meanwhile, much discussion is taking place to improve network energy efficiency in 5G systems. Energy-related discussions are also ongoing within 3GPP. However, discussions on energy efficiency are primarily focused on improving energy efficiency through methods such as reducing the number of transmissions and receptions, such as Discontinuous Reception (DRX) and Discontinuous Transmission (DTX), and / or improving energy efficiency from the operational perspective rather than the system design perspective. However, it is not easy to incorporate energy efficiency into system design, or for the industry to access information on network energy efficiency, and it is also not easy to introduce energy efficiency as a service (e.g., managing transmission speed according to battery status).

[0177] Furthermore, interest in the use of renewable energy and carbon emissions is growing for sustainable development, including ESG (Environment, Social, Governance) management. However, 5G networks lack the functionality to provide external third-party application functions (AFs) or application servers with energy information, such as energy usage status, energy source information, and carbon emissions. Furthermore, the network lacks a method for AFs to verify energy source information. 3GPP is also conducting research on energy efficiency as a service standard. Furthermore, within the 5G system, it may be necessary to structurally expose and exchange energy information between servers and networks, and manage energy usage.

[0178] Additionally, 5G systems do not collect or manage server or terminal energy efficiency or status information. Next-generation wireless communication systems may require monitoring server energy efficiency, terminal battery status, and energy efficiency to manage transmission volume and QoS.

[0179] Existing 5G systems lack the ability to provide network energy information to AFs, and the AF's energy information and UE energy levels could not be verified by the system. If a new network function of the 5G core is defined that can expose and exchange energy information such as energy sources, carbon emissions, and energy consumption between the 5G network and AFs, energy information can be exchanged between the 5G system and third-party AFs, and the exchanged information can be used to adjust transmission rates, such as by guaranteeing better QoS performance to AFs that use renewable energy or have lower carbon emissions.

[0180]

[0181] Accordingly, an Energy Information Repository Function (EIRF) can be defined, which has a new network function that can expose energy information to AFs in next-generation wireless communication systems including 5G systems, collect information about the energy of AFs, and store and manage the energy information. Here, EIRF is an arbitrary name in this specification, and the name of the function can be changed in various ways, such as EECF (Energy Efficiency Control Function). EIRF can perform various functions related to energy, such as energy utilization as a performance criterion for optimal communication, support for various energy efficiency modes in industrial campuses, energy usage exposure considering possible deployment scenarios, energy usage information exposure according to NPN (Non-Public Network) execution sharing, service energy monitoring by application servers, energy usage information exposure considering QoS, support for service-level energy efficiency analysis for industries, application energy efficiency monitoring, exposure of renewable energy usage information, and support for carbon-aware communication services.

[0182] Additionally, the EIRF can provide terminal energy information to a third-party AF, which can then acquire and monitor energy information from the 5G system. Furthermore, the AF can configure the system based on energy efficiency, such as charging or limiting services based on energy information. Furthermore, this function allows the AF to adjust service provision, such as video playback, by checking energy source information or carbon emissions information.

[0183] For example, an EIRF may include / store / provide the following information. The information described below is merely exemplary, and an EIRF may include any information for energy management and energy control in addition to the information disclosed herein.

[0184] For example, the EIRF can contain / store / provide energy information that the AF can provide to the 5G system. For example, this information can include information on energy sources such as renewable energy and thermal energy, information on power consumption, and information on carbon emissions. Furthermore, the EIRF can contain / store / provide energy information that the network provides to the AF. For example, this information can include information on energy sources, energy information on UEs, energy information on the used UPF, information on power consumption, and information on carbon emissions.

[0185] Figure 6 illustrates an example of a 5G system structure with EIRF added.

[0186] Referring to Figure 6, EIRF can interact with NEF, PCF, UDM, etc.

[0187] For example, energy-related policies, such as energy usage and the type of energy used, can be determined through the PCF, and these policies can be transmitted to and applied by the EIRF. In addition, energy-related UE subscription information, such as rate plans and charging policies, can be managed in the UDM. In addition, the NEF can store energy-related information provided by the EIRF as structured data and expose it to other network functions. Meanwhile, FIG. 6 is only an example of a 5G system structure including the EIRF, and the EIRF can interact with various network functions of the 5G system and / or the next-generation wireless communication system, unlike what is illustrated in FIG. 6.

[0188] Figure 7 illustrates another example of a 5G system architecture with EIRF added.

[0189] FIG. 7 illustrates Namf (a service-based interface provided by AMF), Nnef (a service-based interface provided by NEF), Nnrf (a service-based interface provided by NRF), Npcf (a service-based interface provided by PCF), Nudm (a service-based interface provided by UDM), Naf (a service-based interface displayed by AF), Nnssaaf (a service-based interface provided by NSSAAF), Nausf (a service-based interface displayed by AUSF), Namf (a service-based interface provided by AMF), Nsmf (a service-based interface provided by SMF), Nnsacf (a service-based interface provided by NSACF), etc. Referring to FIG. 7, the service-based interface provided by EIRF may be named Neirf. As mentioned above, EIRF and Neirf may also be named by other names.

[0190] Referring to Figure 7, the EIRF can be interconnected with other network functions via a common bus. For example, the EIRF can register the services it provides with the NRF. The EIRF can then use the NRF as a database to search for other network functions and the services they provide. Furthermore, the EIRF can receive service authentication from the NRF to use services provided by other network functions. The EIRF can utilize Hypertext Transfer Protocol version 2 (HTTP / 2) to signal with other network functions.

[0191] In one embodiment, the EIRF may obtain and store information from one or more of the AMF, SMF, UPF, or RAN based on a request from the AF. For example, upon receiving a request from the AF, the EIRF may collect energy consumption-related information (e.g., energy efficiency information, RAN energy consumption information, local renewable energy information, etc.) per NF or per S-NSSAI (Single-Network Slice Selection Assistance Information) via OAM, and generate necessary information.

[0192] For example, the number of registered subscribers, DRX information of the UE, paging-related information, etc. can be obtained from the AMF, the number of PDU sessions, QoS parameters per each PDU session, etc. can be obtained from the SMF, data volume, bit rate, etc. can be obtained from the UPF, and data amount information can be obtained from the RAN.

[0193]

[0194] Meanwhile, in the above description, NF for network energy management is described as an example of one entity (e.g., EIRF), but NF for network energy management may be formed of multiple entities depending on the function.

[0195] For example, an entity that performs energy management on a NF basis, an entity that performs it on a network slice basis, an entity that performs it on a service basis, etc. may be separately defined, or may be defined as a type of such NF. Fig. 8 is a flowchart illustrating an example of the operation of a network function according to some implementations of the present specification. Here, the network function may be the EIRF proposed in the present specification. In addition, some of the steps in the flowchart of Fig. 8 may be omitted or not performed, and the order of the steps may be changed.

[0196] Referring to FIG. 8, the network function may store energy-related information (S810). Here, the network function may receive the energy-related information from another network function.
