[0022] The following embodiments are exemplary. Although this specification may refer to "one," "an," or "some" embodiments in several places throughout the text, this does not necessarily mean that each reference is to the same embodiment(s) or that a particular feature applies only to a single embodiment. Individual features of different embodiments may also be combined to provide other embodiments.

[0023] Example embodiments relate to adapting at least one operating parameter related to radio resource management. More specifically, example embodiments relate to adapting at least one operating parameter in a low power mode related to radio resource management.

[0024] Example embodiments relate to apparatuses on the client side and apparatuses on the network side. The apparatuses on the client side may be terminal devices / user equipment such as mobile computing devices, and the apparatuses on the network side may be comprised by access points such as base stations.

[0025] According to an example embodiment, the device on the client side is configured to: receive a control message including power saving information; determine adaptation of at least one operating parameter related to radio resource management in low power mode based on the power saving information; and cause adaptation of at least one operating parameter related to radio resource management according to the determined adaptation.

[0026] According to an example embodiment, the apparatus on the client side is configured to cause adaptation of at least one operating parameter by requesting the apparatus on the network side to adapt the at least one operating parameter or by the apparatus on the client side adapting the at least one operating parameter.

[0027] According to an example embodiment, the apparatus on the network side is configured to: provide power saving information to adapt at least one operating parameter related to radio resource management in a low power mode of a terminal device; and send a control message including the power saving information to the terminal device.

[0028] According to a further example embodiment, the control message comprises a radio resource control (RRC) message providing power saving information to the device on the client side, the power saving information comprising at least one power saving parameter and / or an instruction to enter a low power mode.

[0029] In the following, as examples of access architectures to which the embodiments may be applied, different exemplary embodiments will be described using a radio access architecture based on Advanced Long Term Evolution (LTE-Advanced, LTE-A) or New Radio (NR, 5G), without, however, limiting the embodiments to such architectures. It will be apparent to a person skilled in the art that the embodiments may also be applied to other kinds of communication networks with appropriate components by appropriately adjusting the parameters and procedures. Some examples of other options for appropriate systems are Universal Mobile Telecommunications System (UMTS) Radio Access Network (UTRAN or E-UTRAN), Long Term Evolution (LTE, same as E-UTRA), Wireless Local Area Network (WLAN or WiFi), Worldwide Interoperability for Microwave Access (WiMAX), , Personal Communications Service (PCS), Wideband Code Division Multiple Access (WCDMA), systems using Ultra-Wideband (UWB) technology, sensor networks, Mobile Ad Hoc Networks (MANETs), and Internet Protocol Multimedia Subsystem (IMS), or any combination thereof.

[0030] Figure 1An example of a simplified system architecture is depicted, showing only some elements and functional entities, all being logical units, the implementation of which may differ from what is shown. Figure 1 The connections shown are logical connections; the actual physical connections may be different. It will be apparent to those skilled in the art that the system may include, in addition to Figure 1 Other functions and structures than those shown.

[0031] However, the embodiments are not limited to the systems given as examples, but a person skilled in the art may apply the solutions to other communication systems provided with the necessary characteristics.

[0032] Figure 1 The example of FIG. 1 shows a portion of an exemplary radio access network.

[0033] Figure 1 Shown are user devices 100 and 102 configured to be wirelessly connected on one or more communication channels in a cell, where an access node (such as an (e / g) NodeB) 104 provides the cell. The physical link from the user device to the (e / g) NodeB is called an uplink or reverse link, and the physical link from the (e / g) NodeB to the user device is called a downlink or forward link. It should be understood that the (e / g) NodeB or its functionality can be implemented using any node, host, server, or access point entity suitable for such use.

[0034] A communication system may include more than one (e / g)NodeB, in which case the (e / g)NodeBs may also be configured to communicate with each other via wired or wireless links designed for this purpose. These links may be used not only for signaling purposes, but also for routing data from one (e / g)NodeB to another. An (e / g)NodeB is a computing device configured to control the radio resources of the communication system to which it is coupled. An (e / g)NodeB may also be referred to as a base station, access point, access node, or any other type of interface device including a relay station capable of operating in a wireless environment. The (e / g)NodeB includes a transceiver or is coupled to a transceiver. A connection is provided from the transceiver of the (e / g)NodeB to an antenna unit, which establishes a bidirectional radio link to a user equipment. The antenna unit may include multiple antennas or antenna elements. The (e / g)NodeB is also connected to the core network 110 (CN or Next Generation Core NGC). Depending on the system, the counterpart on the CN side may be a Serving Gateway (S-GW, routing and forwarding user data packets), a Packet Data Network Gateway (P-GW) for providing connectivity between User Equipment (UE) and external packet data networks, or a Mobility Management Entity (MME), etc.

[0035] User equipment (also referred to as UE, user equipment, user terminal, terminal device, etc.) illustrates a type of device to which resources on the air interface are allocated and assigned, and therefore any features described herein using user equipment can be implemented using corresponding devices such as relay nodes. An example of such a relay node is a layer 3 relay (self-backhaul relay) toward a base station.

[0036] For example, a user device refers to a wireless mobile communication device that operates with or without a subscriber identity module (SIM), including but not limited to the following types of devices: mobile stations (mobile phones), smartphones, personal digital assistants (PDAs), handheld devices, devices using wireless modems (such as alarms or measurement devices), laptop and / or touchscreen computers, tablet computers, game consoles, notebook computers, navigation devices, vehicle infotainment systems, and multimedia devices, or any combination thereof. It should be understood that a user device can also be almost exclusively an uplink-only device, an example of which is a camera or video camera that uploads images or video clips to a network. A user device can also be a device capable of operating in an Internet of Things (IoT) network, which is a scenario in which objects are provided with the ability to transfer data over a network without human-to-human or human-to-computer interaction. User devices can also utilize the cloud. In some applications, a user device can include a small portable device with a radio component (such as a watch, headphones, or glasses), and computing is performed in the cloud. A user device (or, in some embodiments, a layer 3 relay node) is configured to perform one or more of the user device functionalities. A user device may also be called a subscriber unit, a mobile station, a remote terminal, an access terminal, a user terminal, or a user equipment (UE), to mention just a few names or devices.

[0037] Wireless equipment is a general term that covers both access nodes and terminal devices.

[0038] The various techniques described herein can also be applied to cyber-physical systems (CPS) (systems of computing elements that collaboratively control physical entities). CPS can enable the implementation and development of a large number of interconnected ICT devices (sensors, actuators, processors, microcontrollers, etc.) embedded in physical objects at different locations. Mobile cyber-physical systems, in which the physical systems in question have inherent mobility, are a subcategory of cyber-physical systems. Examples of mobile physical systems include mobile robots and electronic products transported by humans or animals.

[0039] Additionally, although the apparatus has been depicted as a single entity, different units, processors and / or memory units (not shown) may be Figure 1 All shown in ) can be implemented.

[0040] 5G enables the use of multiple-input, multiple-output (MIMO) antennas, many more base stations or nodes than LTE (the so-called small cell concept), including macro sites operating in collaboration with smaller stations and employing multiple radio technologies depending on service requirements, use cases and / or available spectrum. 5G mobile communications supports a wide range of content delivery use cases and related applications, including, for example, video streaming, audio streaming, augmented reality, gaming, map data, different ways of sharing data, and various forms of machine-type applications (such as (massive) machine-type communications (mMTC)), including vehicle safety, different sensors and real-time control. 5G is expected to have multiple radio interfaces, namely sub-6 GHz, cmWave and mmWave, and can also be integrated with existing legacy radio access technologies (such as LTE). At least in the early stages, integration with LTE can be achieved as a system where the macro coverage is provided by LTE and the 5G radio interface access comes from the small cells by aggregation to LTE. In other words, 5G is planned to support both inter-RAT operability (such as LTE-5G) and inter-RI operability (inter-radio interface operability, such as sub-6GHz-cmWave, sub-6GHz-cmWave-mmWave). One of the concepts considered for use in 5G networks is network slicing, in which multiple independent and dedicated virtual subnets (network instances) can be created within the same infrastructure to run services with different requirements for latency, reliability, throughput, and mobility.

[0041] The current architecture in LTE networks is fully distributed in the radio and fully centralized in the core network. Low-latency applications and services in 5G require content to be close to the radio, leading to local breakout and multi-access edge computing (MEC). 5G enables analysis and knowledge generation to occur at the data source. This approach requires leveraging resources that may not be continuously connected to the network, such as laptops, smartphones, tablets, and sensors. MEC provides a distributed computing environment for hosting applications and services. It also has the ability to store and process content close to cellular users to speed up response times. Edge computing covers a wide range of technologies, such as wireless sensor networks, mobile data collection, mobile signature analysis, collaborative distributed peer-to-peer networking and processing, and can also be categorized as local cloud / fog computing and grid / mesh computing, exposed computing, mobile edge computing, micro-clouds, distributed data storage and retrieval, autonomous self-healing networks, remote cloud services, augmented and virtual reality, data caching, the Internet of Things (large-scale connectivity and / or latency-critical), and critical communications (autonomous vehicles, traffic safety, real-time analytics, time-critical control, and healthcare applications).

[0042] The communication system may also be capable of communicating with or utilizing services provided by other networks such as the public switched telephone network or the Internet 112. The communication network may also be capable of supporting the use of cloud services, for example, at least a portion of the core network operations may be performed as a cloud service (this is in the context of Figure 1 114). The communication system may also include a central control entity or the like, which provides facilities for networks of different operators to cooperate, for example in spectrum sharing.

[0043] The edge cloud can be brought into the radio access network (RAN) by leveraging network function virtualization (NVF) and software-defined networking (SDN). Using the edge cloud may mean that access node operations will be performed at least partially in a server, host or node that is operably coupled to a remote radio head or base station that includes radio components. It is also possible that node operations will be distributed among multiple servers, nodes or hosts. The application of the cloudRAN architecture enables RAN real-time functions to be performed on the RAN side (in the distributed unit DU 104) and non-real-time functions to be performed in a centralized manner (in the centralized unit CU 108).

[0044] It should also be understood that the distribution of labor between core network operations and base station operations may be different from LTE, or even non-existent. Some other technological advancements that may be used are big data and all-IP, which may change the way networks are built and managed. 5G (or New Radio NR) networks are designed to support multiple hierarchical structures, where MEC servers can be placed between the core and base stations or Node Bs (gNBs). It should be understood that MEC can also be applied to 4G networks.

[0045] 5G can also leverage satellite communications, for example by providing backhaul, to enhance or supplement the coverage of 5G services. Possible use cases are providing service continuity for machine-to-machine (M2M) or Internet of Things (IoT) devices or onboard passengers, or ensuring service availability for critical communications and future rail, maritime and / or aviation communications. Satellite communications can leverage geostationary Earth orbit (GEO) satellite systems as well as low Earth orbit (LEO) satellite systems, particularly mega-constellations (systems where hundreds of (nano)satellites are deployed). Each satellite 106 in a mega-constellation can cover multiple satellite-enabled network entities creating terrestrial cells. Terrestrial cells can be created by ground relay nodes 104 or by gNBs located on the ground or in satellites.

[0046] It will be apparent to those skilled in the art that the depicted system is merely an example of a portion of a radio access system, and that in practice the system may include multiple (e / g)NodeBs, user equipment may access multiple radio cells, and the system may also include other devices, such as physical layer relay nodes or other network elements. At least one (e / g)NodeB may be a home (e / g)NodeB. Additionally, multiple different types of radio cells, as well as multiple radio cells, may be provided within a geographical area of the radio communication system. A radio cell may be a macro cell (or umbrella cell), which is a large cell typically having a diameter of up to tens of kilometers, or a small cell such as a micro cell, a femto cell, or a pico cell. Figure 1 An (e / g)NodeB can provide any of these cells. A cellular radio system can be implemented as a multi-layer network comprising multiple types of cells. In a multi-layer network, one access node provides one or more types of cells, so multiple (e / g)NodeBs are required to provide this network structure.

[0047] In order to meet the needs of improving the deployment and performance of communication systems, the concept of "plug and play" (e / g) NodeB has been introduced. In addition to the home (e / g) NodeB (H(e / g)nodeB), the network that can use "plug and play" (e / g) NodeB also includes the home node B gateway or HNB-GW (not in Figure 1 ). An HNB gateway (HNB-GW) that may be installed within the operator's network may aggregate services from a large number of HNBs back to the core network.

[0048] As is generally known in connection with wireless communication systems, control or management information is communicated between, for example, the terminal device 100 and the access node 104 over the radio interface.

[0049] A terminal device such as a UE may be surrounded by multiple radio access networks (RANs) such as base stations, but the UE may be registered to only one cell. Cell selection is the process of selecting a cell to register to. Cell selection may be performed based on one or more cell selection criteria. The cell selection criteria may include different types of criteria, such as signal strength or signal quality criteria, public line mobile network (PLMN) criteria, or service type criteria. The one or more cell selection criteria may include, for example, criteria indicating whether the transmit power of the cell is strong enough to be detected by the UE, whether the public land mobile network PLMN is acceptable to the UE, or whether the service type of the cell is acceptable to the UE.

[0050] After a UE is registered with a cell, that cell is considered the serving cell. The UE is also configured to monitor system information and perform radio resource management (RRM) measurements on the serving cell and neighboring cells after registering with the cell. Based on the monitoring and performed measurements, the UE may select another cell to register with if some other cell is deemed a more suitable cell based on cell reselection criteria.

[0051] However, RRM measurements can drain the UE battery and avoiding unnecessary measurements is beneficial. On the other hand, if measurements are avoided so that the UE remains registered to a less than optimal cell, transmissions associated with connection establishment may cause inter-cell interference and additional handovers at the start of the connection.

[0052] Figure 2 An exemplary apparatus is shown in the example of FIG.

[0053] Figure 2 2 is a block diagram illustrating an apparatus 200 operating in accordance with an example embodiment of the present invention. The apparatus 200 may be, for example, an electronic device such as a chip, a chipset, an electronic device, a terminal device, a network function, or an access node such as a base station. The apparatus includes one or more control circuit systems, such as at least one processor 210 and at least one memory 260, including one or more algorithms, such as computer program instructions 220, wherein the at least one memory 260 and the computer program instructions 220 are configured to, together with the at least one processor 210, cause the apparatus 200 to perform any of the example functionalities described below.

[0054] exist Figure 2 In the example of the present invention, the processor 210 is a central unit that is operatively connected to read from and write to the memory 260. The processor 210 may also be configured to receive control signals received via the input interface and / or the processor 210 may be configured to output control signals via the output interface. In an example embodiment, the processor 210 may be configured to convert the received control signals into appropriate commands for controlling the functionality of the device.

[0055] The memory 260 stores computer program instructions 220 which, when loaded into the processor 210, control the operation of the apparatus 200, as explained below. In other examples, the apparatus 200 may include more than one memory 260 or different kinds of storage devices.

[0056] The computer program instructions 220 for implementing the exemplary embodiments of the present invention, or a portion of such computer program instructions, may be loaded onto the apparatus 200 by the manufacturer of the apparatus 200, by a user of the apparatus 200, or by the apparatus 200 itself based on a download procedure, or the instructions may be pushed to the apparatus 200 by an external device. The computer program instructions may arrive at the apparatus 200 via an electromagnetic carrier signal, or may be copied from a physical entity such as a computer program product, a memory device, or a recording medium (such as a compact disc (CD), a compact disc read-only memory (CD-ROM), a digital versatile disc (DVD), or a Blu-ray disc).

[0057] According to an example embodiment, the apparatus 200 comprises a terminal device. The apparatus 200 is configured to communicate with a radio access network (RAN) 280. The terminal device may comprise a UE, such as a mobile computing device.

[0058] According to an example embodiment, apparatus 200 is configured to monitor system information and perform radio resource management (RRM)-related measurements on a serving cell and one or more neighboring cells. RRM measurements are used, for example, to measure the signal strength and / or quality of neighboring cells for cell selection / reselection and handover when a UE moves from cell to cell.

[0059] RRM measurements may include, for example, intra-frequency measurements and / or inter-frequency measurements. Intra-frequency measurements include measurements related to cells operating on the same carrier frequency as the serving cell. Intra-frequency measurements include measurements related to cells operating on a carrier frequency different from the serving cell. RRM measurements may include metrics such as reference signal received power (RSRP), reference signal received quality (RSRQ), and signal-to-noise ratio (SINR). RRM may be implemented using radio resource control (RRC).

[0060] Radio Resource Control (RRC) is a protocol that includes functions related to communication between a terminal device and a radio access network (RAN), such as a gNodeB or eNodeB. For example, RRC includes connection establishment and release functions, broadcasting of system information (SI), and establishment, reconfiguration, and release of radio bearers between the terminal device and the RAN.

[0061] The operation of the RRC is guided by a state machine that defines specific states for the UE. The RRC states include a connected state (such as RRC_CONNECTED in the 3GPP specification), an inactive state (such as RRC_INACTIVE in the 3GPP specification), and an idle state (such as RRC_IDLE in the 3GPP specification). In different states, the UE has different amounts of available radio resources. The UE is also configured to switch from the first state to the second state in response to receiving a command from the network.

[0062] According to an example embodiment, the apparatus 200 is configured to receive a control message comprising power saving information.The apparatus 200 is configured to receive the control message from a RAN 280, such as a gNodeB or an eNodeB.

[0063] According to an example embodiment, the apparatus 200 is configured to send a request for low power operation.

[0064] According to an example embodiment, the apparatus 200 is configured to receive a control message in response to sending a request for low power operation.

[0065] According to an example embodiment, the request for low-power operation includes a request for a low-power mode and / or a request to provide power saving information based on power saving parameters preferred by the apparatus 200. The parameters preferred by the apparatus 200 may include, for example, an indication of a preference to operate in a low-power mode, an indication of overheating, a request for overheat assistance, an indication of a delay budget report, and / or a request to change an operating parameter.

[0066] The preference indication for operating in low power mode may include one or more states. The one or more states may include, for example, a normal state, a state indicating a preference for power saving, an RRC released state, and a state indicating a preference for power saving in an RRC connected state.

[0067] The request for overheat assistance may include, for example, a request to adapt one or more operating parameters, such as the number of MIMO layers, the number of component carriers, the operating bandwidth or a specific frequency range for the uplink and / or downlink.

[0068] The indication of the delay budget report may include, for example, a request to change or adapt a discontinuous reception cycle (DRX).

[0069] The apparatus 200 may be configured to provide, in an RRC message, parameters preferred by the apparatus 200. These parameters may be provided by the apparatus 200 in UE assistance information of the 3GPP specification, in MAC CE or L1 signaling.

[0070] The RRC message may include multiple information elements. For example, when the RRC message includes a request for overheat assistance and a preference for operating in low power mode, the network-side device is configured to interpret that the device 200 prefers low power mode, the parameters of which are provided in the request for overheat assistance. As another example, when the RRC message includes an indication of a delay budget report and a preference for operating in low power mode, the network-side device is configured to interpret that the device 200 prefers low power mode, the parameters of which are provided in the indication of the delay budget report. As another example, when the RRC message includes a preference for operating in low power mode and both a request for overheat assistance and an indication of a delay budget report, the network-side device is configured to interpret that the device 200 prefers low power mode, the parameters of which are provided in the indication of the delay budget report and the parameters are provided in the request for overheat assistance.

[0071] As another example, when the RRC message includes an indication of a delay budget report and an indication of a preference for operating in a low power mode, or an indication that device 200 requests / prefers a lower power mode with indicated parameters. In this example, when the indication is provided together with or associated with the provided indication of a delay budget report, the network side is configured to interpret that device 200 prefers a low power mode, the parameters of which are provided in the indication of the delay budget report. In some examples, the indication may be a power preference indication. In some examples, the indication may be an indication associated with a delay budget report, wherein device 200 requests or prefers a low power mode with indicated parameters. When the indication is not provided, or in other words, the indication is not set, the auxiliary information is interpreted as a request for configuration of a preferred delay budget.

[0072] As another example, when the RRC message includes an indication of overheat assistance information and a preference for operating in low power mode or an indication that device 200 requests / prefers a lower power mode with indicated overheat assistance parameters. In the example, when the indication is provided together or the indication is associated with the provided indication of overheat assistance information, the network side is configured to interpret that device 200 prefers a low power mode, whose parameters are provided in the indication of overheat assistance information. In some examples, the indication can be a power preference indication. In some examples, the indication can be an indication associated with overheat assistance information, wherein device 200 requests or prefers a low power mode with the indicated parameters. When the indication is not provided or in other words, the indication is not set by device 200, the overheat assistance information is interpreted as a request for overheat configuration (i.e., the UE has experienced / detected overheating).

[0073] The RRC message may also include an indication that the device 200 prefers to release the RRC connection or an indication that the device 200 prefers not to release the RRC connection. For example, if the preference for operating in low power mode is not included in the RRC message, the network-side device may be configured to determine that the device 200 prefers to release the RRC connection. However, if the preference for operating in low power mode is included in the RRC message, the network-side device 200 may be configured to determine that the device prefers not to release the RRC connection.

[0074] The power saving information may include different types of information related to the low power mode. For example, the power saving information may include information related to entering the low power mode and / or one or more parameters related to the low power mode.

[0075] According to an example embodiment, the power saving information includes instructions to enter a low power mode.

[0076] The power saving information may include information related to a low-power mode of device 200. The low-power mode enables reduced power consumption of device 200, for example, by reducing the number of operations performed by device 200. For example, device 200 may be configured to enter low-power mode when it is not transmitting or receiving data. In low-power mode, the power consumption of device 200 is less than that in active mode. According to an example embodiment, the low-power mode of device 200 includes a mode in which device 200 has fewer available radio resources than in active mode.

[0077] According to an example embodiment, the control message includes a connection release message.
