Description

Technical Field

[0001] The present disclosure relates to a communication device and a communication method capable of performing wireless communication with a terminal (User Equipment, UE). Background Art

[0002] The 3rd Generation Partnership Project (3GPP: registered trademark) has standardized the fifth-generation mobile communication system (also referred to as 5G, New Radio (NR), or Next Generation (NG)), and is also standardizing the next generation referred to as Beyond 5G, 5G Evolution, or 6G.

[0003] For example, in the white paper related to 6G (non-patent document 1), research is being conducted on network architecture, including more flexible network function configuration.

[0005] Non-patent literature

[0006] Non-Patent Document 1: NTT Docomo, “Docomo 6G White Paper Version 5.0,” [Online] January 2023, Internet <URL:https: / / www.docomo.ne.jp / binary / pdf / corporate / technology / whitepaper_6g / DOCOMO_6G_White_PaperJP_20221116.pdf> Summary of the Invention

[0007] In 6G, as one of the methods of mobile communication network architecture, it is planned to introduce Network Controlled Access Point (NCAP, provisional name) as an access point (communication device) that can be set up under the mobile communication network and can be actively controlled by the network operator.

[0008] In a mobile communication network including NCAP (may also be referred to as an NCAP network), it is envisaged that a network self-optimization function provided on the network operator side, a so-called SON (Self Organizing Networks) function, is utilized.

[0009] However, existing SON functions involve properly configuring (deploying) wireless base stations (gNBs) on the network operator side and then adjusting configuration parameters based on traffic volume. Therefore, it is not necessarily appropriate to apply such conventional SON functions to NCAPs that can be configured by subscribers of communication services.

[0010] Therefore, the following disclosure has been made in view of such circumstances, and an object of the disclosure is to provide a communication device and a communication method that can achieve appropriate self-optimization of an NCAP network.

[0011] One embodiment of the present disclosure is a communication device (NCAP100), which includes: a communication unit (a first communication unit 110, a second communication unit 120, and a third communication unit 130), which performs communication with a first communication network and a second communication network, and wireless communication with a terminal (UE200); and a control unit (control unit 140) which performs optimization of the specific communication network based on setting information or recommendation information related to the setting of the specific communication network constructed using the communication unit.

[0020] Hereinafter, the embodiment will be described with reference to the accompanying drawings. The same or similar reference numerals will be given to the same functions and structures, and their description will be omitted as appropriate.

[0021] (1) Overall schematic structure of wireless communication system

[0022] Figure 1This is a schematic diagram of the overall structure of wireless communication system 10 according to this embodiment. Wireless communication system 10 is a wireless communication system that complies with standards known as Beyond 5G, 5G Evolution, or 6G (hereinafter referred to as 6G), and includes a wireless base station 50 (hereinafter referred to as gNB 50) and a terminal 200 (hereinafter referred to as UE 200, or User Equipment, or UE). Wireless communication system 10 may also comply with standards other than 6G, such as 5G New Radio (NR).

[0023] The gNB 50 is a 6G-compliant radio base station that performs 6G-compliant wireless communications with the UE 200. By controlling radio signals transmitted from multiple antenna elements, the NCAP 100 and UE 200 support Massive MIMO (Multiple-Input Multiple-Output), which generates more directional antenna beams; Carrier Aggregation (CA), which bundles and uses multiple component carriers (CCs); and Dual Connectivity (DC), which enables simultaneous communication between the UE and two or more RAN nodes.

[0024] In addition to the gNB 50, the wireless communication system 10 also includes a network control access point 100 (hereinafter referred to as NCAP 100). NCAP 100 is a type of communication device known as an access point (AP) and can provide the same functions as a wireless base station. NCAP is a temporary term and may also be referred to by other similar names such as communication node, RAN node, relay device, etc.

[0025] NCAP 100 may be set by the operating entity of the wireless communication system 10 (mobile communication system) (also referred to as a network operator or mobile operator, etc.), or may be freely set by a subscriber (Customer, Subscriber) of the communication service provided by the wireless communication system 10 .

[0026] Furthermore, compared to gNB 50, at least one of the frequency bands (which may include frequency band combinations, etc.), number of antenna beams, number of MIMO layers, and transmit power supported by NCAP 100 may be restricted. Because NCAP 100 can provide essentially the same functionality as gNB 50, it can form cell C1 and accommodate UE 200.

[0027] The UE 200 is typically a portable terminal such as a smartphone, but may also be a device for the Industrial Internet of Things (IIoT) or URLLC (Ultra-Reliable and Low Latency Communications).

[0028] The wireless communication system 10 may be composed of a radio access network (RAN) composed of multiple RAN nodes such as gNB 50 using 6G radio access technology (RAT), and a core network compliant with 6G. The RAN and core network may be simply referred to as "network."

[0029] The core network (CN) can be connected to the RAN and is a network composed of a switch, a subscriber information management device, etc. The UE 200 can communicate with the core network via the RAN.

[0030] In the wireless communication system 10 , a control plane (C-plane) function and a user plane (U-plane) function (UPF: User Plane Function) are defined.

[0031] The C-plane may refer to a series of control processes exchanged mainly for establishing communications, etc. The U-plane may refer to a process for transmitting and receiving user data.

[0032] In the core network (and part of the RAN), the concept of CUPS (Control and User Plane Separation) can be introduced, in which the functions of the C-plane and U-plane are clearly separated.

[0033] The C-plane functions of the core network may include: an access and mobility management function (AMF) that provides access and mobility management functions for UE 200, a session management function (SMF) that provides session management functions, etc. In addition, AMF and SMF may also be referred to by other names.

[0034] For NCAP 100, network operators can connect to the RAN and perform various controls via C-plane functionality. At least a portion of this connection and / or control can also be implemented using the Self-Organizing Network (SON) framework. SON can be interpreted as a self-optimizing function of the mobile communication network, including automatic configuration during gNB 50 installation and automatic parameter optimization.

[0035] As described above, NCAP 100 can connect to gNB 50 via the C-plane function. The connection between gNB 50 and NCAP 100 can be via the RAN (RAT) or a wired network. Furthermore, NCAP 100 can provide UE 200 with a communication path to the broadband internet and servers for MEC (Multi-access Edge Computing) via a local area network (LAN). MEC is a mechanism that deploys servers and storage closer to users (subscribers) in mobile communication networks. Furthermore, various cloud services can be accessed via the broadband internet.

[0036] (2) Functional block structure of wireless communication system

[0037] Next, the functional block configuration of the wireless communication system 10 will be described. Specifically, the functional block configurations of the NCAP 100 and the UE 200 will be described. Figure 2 This is the functional block structure diagram of NCAP100. Figure 3 FIG. 2 is a functional block diagram of UE 200 .

[0038] (2.1) NCAP100

[0039] like Figure 2 As shown, the NCAP 100 includes a first communication unit 110 , a second communication unit 120 , a third communication unit 130 , and a control unit 140 .

[0040] The first communication unit 110 performs communication with the network operator side. Specifically, the first communication unit 110 performs communication with the RAN node including the gNB50. The connection with the gNB50 (and other RAN nodes) can use the radio access technology (RAT) or a wired network other than the RAT. The network on the network operator side composed of the RAN node including the gNB50, etc. can also be called the first communication network. That is, the first communication unit 110 uses the RAT to perform communication with the first communication network. The network on the network operator side can be simply referred to as the network operator, and can also be interpreted as including the concept of SON.

[0041] The second communication unit 120 performs communication with a local area network (LAN). Specifically, the second communication unit 120 performs communication via a communication device such as a router constituting the LAN and the broadband Internet (which may be omitted as simply the Internet).

[0042] The connection to the LAN can be a wireless LAN such as Wi-Fi (registered trademark) or a wired LAN such as Ethernet (registered trademark). The network on the LAN side can also be called a second communication network. That is, the second communication unit 120 uses LAN technology to perform communication with the second communication network.

[0043] In addition, the second communication unit 120 can communicate with the network operator via the LAN (second communication network) and the broadband Internet. This communication is not limited to the U-plane function, and may also include communication related to the C-plane function.

[0044] The third communication unit 130 performs communications with the UE 200. Specifically, the third communication unit 130 performs wireless communications with the UE 200 using a radio access technology (RAT). In this case, the NCAP 100 can provide the same functionality to the UE 200 as the gNB 50. In this embodiment, the third communication unit 130 constitutes the communication unit that performs wireless communications with the UE 200.

[0045] The control unit 140 controls the functional blocks that make up the NCAP 100. In particular, in this embodiment, the control unit 140 can control the behavior of the communication device of the NCAP 100. Specifically, the control unit 140 can execute actions (hereinafter referred to as specific actions) as a network device (NW device) that enables the NCAP 100 to accommodate the UE 200.

[0046] The network device is not particularly limited in type, as long as it accommodates UE 200 (and is intended to connect to UE 200 and perform wireless communications). Here, it may refer to a network device such as a wireless base station (gNB 50), and control unit 140 may perform specific operations as a wireless base station accommodating UE 200.

[0047] The control unit 140 can perform NCAP network optimization based on information related to a specific communication network constructed using at least any one of the first communication unit 110, the second communication unit 120 and the third communication unit 130, specifically a mobile communication network including NCAP (also referred to as NCAP network).

[0048] NCAP network optimization refers to setting parameters related to NCAP network components to appropriate values ​​based on the performance and environment required by the NCAP network. In a broad sense, it can be interpreted as the same as the network's self-optimization function (SON: Self-Organizing Networks).

[0049] The control unit 140 can optimize the NCAP network based on configuration information or recommended information related to the NCAP network. Configuration information can be interpreted as information indicating the values ​​to be set for parameters related to the components of the NCAP network. Recommended information is the recommended value (which can be one or more) for the parameter and can be interpreted as information that can be changed based on measurement results, etc. Configuration information and recommended information can be pre-set in the NCAP 100 or notified to the NCAP 100 via the network operator's network or the LAN network.

[0050] The control unit 140 can set the components of the NCAP network based on the values ​​of parameters and the like indicated by the setting information or the recommendation information. The components of the NCAP network are not particularly limited.

[0051] Specifically, the control unit 140 can perform optimization based on configuration information or recommended information related to physical components of the NCAP network. Examples of physical components include parameters related to antennas. The parameters of physical components will be described later. Furthermore, non-physical components related to the NCAP network (such as various wireless parameters) may also be optimized.

[0052] The control unit 140 can perform optimization based on setting information or recommendation information targeting a single NCAP 100 or multiple NCAPs. Specifically, the control unit 140 can perform optimization based on setting information or recommendation information targeting only the NCAP 100, or setting information or recommendation information targeting multiple NCAPs including the NCAP 100, notified from the network operator's network (or the LAN).

[0053] The control unit 140 may also be configured to receive configuration information or recommendation information from the network operator's network (first communication network) within a specific time period after the configuration information indicating the configuration of the NCAP network is reported from the NCAP 100 or the UE 200. The configuration information indicating the configuration of the NCAP network may be parameters similar to the configuration information or recommendation information described above, or may refer to values ​​already set for the components of the NCAP network.

[0054] Furthermore, the control unit 140 may also be configured to receive the configuration information or recommendation information from the network operator within a specific time period after receiving a configuration information or recommendation information request from the NCAP 100 or the UE 200. If the control unit 140 fails to receive the configuration information or recommendation information within the specific time period, the control unit 140 may request the configuration information or recommendation information again or may re-report the configuration information.

[0055] After the configuration changes associated with the optimization, the control unit 140 may also report configuration information related to the changed components to the network operator. Specifically, the control unit 140 may report configuration information related to the changed components within a specified time period after the configuration changes. This configuration information may only include the changed components or may include parameters associated with the components.

[0056] The control unit 140 can execute specific actions in at least one of the C-plane of the NCAP 100 or UE 200 related to the CN and the U-plane of the UE 200 related to the CN. The C-plane function and the U-plane function of the CN may include the following processes.

[0057] C-plane functions: device registration / connection, subscriber-related management / maintenance / processing, subscriber (terminal) authentication processing, charging-related control, mobility management, and session management

[0058] U-plane: Connection to IP (Internet Protocol) networks, authentication processing, IP packet routing, and priority control

[0059] (2.2)UE200

[0060] like Figure 3 As shown, the UE 200 includes a wireless communication unit 210 , a connection IF unit 220 , and a control unit 230 .

[0061] The wireless communication unit 210 transmits and receives 6G-compliant wireless signals with the gNB 50 or NCAP 100. Specifically, the wireless communication unit 210 transmits 6G-compliant UL signals and receives 6G-compliant DL signals. The wireless communication unit 210 supports Massive MIMO, Carrier Access Control (CA), which bundles multiple CCs, and Direct Connection (DC), which allows simultaneous communication between the UE and two NG-RAN nodes.

[0062] The connection IF unit 220 can provide an interface (IF) function for connecting to IIoT-oriented or URLLC-oriented devices, etc. The connection IF unit 220 is not required and may not be provided depending on the specifications of the UE 200. The IF provided by the connection IF unit 220 can be wired or wireless.

[0063] The control unit 230 controls the wireless communication unit 210 and the connection IF unit 220. In particular, in this embodiment, when the NCAP 100 performs a specific operation (operation as a network device accommodating the UE 200) without performing communication with the network of the network operator, the control unit 230 can connect to the NCAP 100.

[0064] Specifically, when the NCAP 100 is executing a specific action (before the execution, a connection request may be sent), the control unit 230 can connect to the NCAP 100 and receive provision of various communication services.

[0065] Furthermore, the control unit 230 may send a request for setting information or recommendation information related to the setting of the NCAP network to the network operator (and NCAP 100 ). For example, the control unit 230 may send the request when connecting to NCAP 100 .

[0066] (3) Operation of wireless communication system

[0067] Next, the operation of the wireless communication system 10 will be described. Specifically, the operation related to self-optimization in the mobile communication network (NCAP network) including the NCAP 100 will be described.

[0068] (3.1) Prerequisites

[0069] In the NCAP network, it is envisaged to utilize the self-optimization function of the network (equivalent to SON) set up on the network operator side. In addition, SON can also be called other similar names.

[0070] Conventional SON functions involve properly configuring (deploying) wireless base stations (gNBs) on the network operator side and then adjusting configuration parameters based on traffic volume. Therefore, applying these conventional SON functions to NCAPs that can be configured by subscribers of communication services is not necessarily appropriate.

[0071] The following describes an example of operations related to self-optimization (SON) of the NCAP network (in a narrower sense, this can be interpreted as NCAP itself or the NCAP concept). This optimization control can include the following stages. These can also be defined in other frameworks and are not limited to SON functions.

[0072] (i) Information collection for optimized control

[0073] (ii) Parameter settings for optimization

[0074] (iii) Controls involved in optimizing equipment settings

[0075] Hereinafter, the contents related to (ii) and (iii) will be described in particular.

[0076] (3.2) Action Overview

[0077] In such Figure 1In the NCAP network shown, the C-plane function and the U-plane function of the core network (CN) can be configured as follows:

[0078] CN C-plane function: In-network on the network operator side

[0079] CN U-plane function: within NCAP100 (or within the network on the NCAP100 side)

[0080] In addition, as described above, the C-plane function and the U-plane function may include the following processing.

[0081] C-plane functions: device registration / connection, subscriber-related management / maintenance / processing, subscriber (terminal) authentication processing, charging-related control, mobility management, and session management

[0082] U-plane functions: connection to IP (Internet Protocol) networks, authentication processing, IP packet routing, and priority control

[0083] Figure 4 A configuration example (part 1) of the C-plane function and the U-plane function of the CN in the mobile communication network configured using the NCAP 100 is shown.

[0084] like Figure 4 As shown, when NCAP 100 is connected to a network operator, it can communicate with the network operator's network via the RAN (using the RAT). Specifically, information related to the connection between NCAP 100 and the network operator's network (e.g., gNB 50 or AMF / SMF constituting the core network) can be exchanged through wireless communication with gNB 50, or NCAP 100 can perform connection actions as a UE.

[0085] Figure 5 The following shows a configuration example (Part 2) of the CN C-plane function and the U-plane function in a mobile communication network configured using the NCAP 100. Specifically, when the NCAP 100 is connected to a network operator, communication with the network operator's network can be performed via broadband Internet.

[0086] In application Figure 4 and Figure 5 In the case of the network architecture shown, the C-plane function of CN (function 1 in the figure) can also be configured in the network on the network operator side, and the U-plane function of CN (function I in the figure) can also be configured in NCAP100.

[0087] (3.3) Action example

[0088] (3.3.1) Basic operation example

[0089] NCAP 100 may receive setting information or recommendation information related to the NCAP network from a SON function (or a SON mechanism) within the network of a network operator, set related parameters based on the information, and perform optimization.

[0090] Figure 6 An example of communication timing related to the optimization of the NCAP network is shown. Figure 6 The timing sequence shown shows a part of the timing sequence related to the following operation example. The order of the timing sequence can be appropriately changed, and a part of the timing sequence can be omitted.

[0091] NCAP 100 may perform this optimization before executing an action (specific action) as a network device (NW device) accommodating UE 200, or may perform the optimization during execution of the specific action. Furthermore, this optimization may be performed repeatedly, periodically, or irregularly, depending on the status of the NCAP network.

[0092] Therefore, the network operator can optimize the NCAP network according to the values ​​of various parameters indicated by the setting information or recommendation information.

[0093] (3.3.2) Action Example 1

[0094] The setting information or recommendation information may be targeted at physical components. For example, regarding the antenna of the NCAP 100 (or UE 200 ), the following components can be listed.

[0095] Antenna (type, pattern, directivity, number of elements, element spacing and arrangement, number of panels, beamforming capability (number of beams, beam width, etc.)

[0096] Pointing direction, tilt angle, antenna height, output (maximum / minimum / granularity), gain, setting position

[0097] New coverage areas, absolute and / or relative locations of cooperating NCAPs

[0098] By targeting such components, it is possible to set, for example, which antenna element to use and what beam pattern to set. In addition, the information represented by the setting information or recommendation information may be the setting value itself or the difference from the value in application.

[0099] Furthermore, the setting information or recommendation information may also target non-physical components. For example, wireless parameters may be targeted, and the following parameters may be included.

[0100] Frequency / time / code-resources (frequency band / band combination / carrier component / signal sequence, etc.)

[0101] Carrier aggregation / dual connectivity (CA / DC)

[0102] Special Cell (SpCell), MCS (Modulation and Coding Scheme), rank

[0103] Reference signals (DMRS / PTRS / SRS / CSIRS / PRS / TRS / etc.)

[0104] Duplex mode (TDD / FDD / FD / etc.)

[0105] Beam management, beam failure recovery, prioritization, and repetition

[0106] Code division multiplexing (TD-OCC / FD-OCC / cyclic shift, etc.)

[0107] SSB / PRACH configurations, numerology / waveform

[0108] Frequency resource configuration (cell / band / FR / BWP / etc.)

[0109] PDCCH configuration (search space / CORESET / DCI format, etc.)

[0110] ·PUCCH configurations, PDSCH configurations, PUSCH configurations

[0111] UE state, power saving (discontinuous reception (DRX), etc.), paging

[0112] Power control, measurement report, and handover (HO)

[0113] RLM (Radio Link Monitoring) / RLF (Radio Link Failure), TA (Timing Advance)

[0114] IoT / RedCap (Reduced UE Capability), cell reselection

[0115] PHR (Power Headroom Report), slicing, QoS (Quality of Service) management, bearer, cell ID

[0116] Regarding service conditions, the following parameters may be included.

[0117] Service types (eMBB (enhanced Mobile Broadband) / URLLC (Ultra-Reliable and Low Latency Communications) / IoT / MBS (Multicast and Broadcast Services) / Positioning / Sensing / Power-transfer, etc.)

[0118] Expected performance (throughput (overall or individual) / capacity (number of units accommodated, etc.) / power consumption (communication time, etc.) / reliability / latency / UE speed / UE device type)

[0119] Furthermore, regarding other NCAPs cooperating with the NCAP 100 , parameters such as a method of cooperating, settings or recommended contents for other NCAPs, and settings for communication with other NCAPs may be targeted.

[0120] Regarding the specifications for parameter settings and scheduling actions, any of the following can be applied.

[0121] Proportional Fairness, Latency-awareness

[0122] Determine the specifications for reporting CSI (Channel State Information), MCS of measured RSRP (Reference Signal Received Power), and other parameters in NCAP

[0123] The settings related to the optimization may be set in units of slices (network slices) or for each installation location, etc. Regarding the above parameters, the setting values ​​themselves may be notified, or the difference from the values ​​in the application may be notified.

[0124] Furthermore, NCAP 100 may also assume that the value of setting information or recommendation information is set in a range included in the applicable parameters reported from NCAP 100 to the network operator.

[0125] (3.3.3) Action Example 2

[0126] The NCAP 100 can receive the setting information or the recommendation information via any of the following communication paths.

[0127] BS (gNB50) to NCAP

[0128] BS to UE to NCAP

[0129] BS to NCAP to NCAP

[0130] The BS (gNB50) can be replaced by the network operator. Setting information or recommendation information can be notified individually for each NCAP or collectively for multiple NCAPs.

[0131] (3.3.4) Action Example 3

[0132] The NCAP 100 can receive the setting information or recommendation information through any of the following operations.

[0133] (a) Periodically receive

[0134] You can notify only the changed parts, or if there are no changes, you can also notify that there are no changes.

[0135] (b) The network operator receives the data at the necessary timing.

[0136] That is, it is conceivable that the NCAP 100 may be received before and / or during the execution of an action (specific action) as a network device accommodating the UE 200 .

[0137] (c) After the configuration information is reported from the NCAP 100 and / or the UE 200, it is received within a predetermined time T1 (see Figure 6 )

[0138] (d) NCAP 100 and / or UE 200 sends a request for setting information or recommendation information to the network operator, and after sending, the request is received within a predetermined time T2 (see Figure 6 )

[0139] This request may also be a request related to another NCAP (for example, when interference from NCAP#1 to NCAP#2 is significant, NCAP#2 requests the network operator to change the settings of NCAP#1).

[0140] (e) Received together with a notification of execution / continuation permission of an action (specific action) as a network device accommodating UE 200

[0141] (z) After receiving the setting information or recommendation information, the NCAP 100 may complete the change of the setting within a predetermined time Te.

[0142] In addition, T1 / T2 / Te may be pre-defined according to 3GPP specifications, or may be notified to NCAP 100 from the network operator as needed.

[0143] (3.3.5) Action Example 4

[0144] NCAP 100 may report the received setting information or recommendation information to a higher layer. The higher layer may include at least one of the following.

[0145] Media Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), Service Data Adaptation Protocol (SDAP), Radio Resource Control (RRC)

[0146] Core network functions (such as UPF)

[0147] Application layer

[0148] NCAP 100 may have the function of prompting changes to physical components based on the received recommendation information. Furthermore, after changing physical components based on the recommendation information, NCAP 100 may report information related to the changed components (component information) to the network operator. Alternatively, NCAP 100 may simply notify the network operator of the change completion.

[0149] The network operator may also consider changing the parameter within a predetermined time T3 after NCAP 100 receives the recommendation information (see Figure 6 If there is no notification within T3, it may mean that there is no change. Alternatively, NCAP 100 may report to the network operator that there is no change after T3 has passed.

[0150] (4) Action and Effect

[0151] According to the above embodiment, the NCAP 100 can optimize the NCAP network based on the setting information or the recommendation information, thereby enabling appropriate self-optimization of the NCAP network in accordance with the intention of the network operator or the status of the NCAP network.

[0152] (5) Other Implementation Methods

[0153] As mentioned above, although embodiment was described, it is not limited to description of this embodiment, Various deformation|transformation and improvement are possible, and it is obvious to those skilled in the art.

[0154] For example, in the above-mentioned embodiment, a case where a connection with a server for MEC and the broadband Internet is possible via a LAN is described, but the LAN can be set in the same segment or can be different LANs that are physically or logically separated.

[0155] In the above embodiment, NCAP 100 is connected to both the network operator's network (first communication network) and the LAN (second communication network), but it may also be connected to only one of the networks. Furthermore, UE 200 connected to the network formed by NCAP 100 may or may not be connected to the network operator's wireless base station. The presence or absence of this connection may also affect the behavior of NCAP 100 and / or UE 200. Furthermore, the network formed by NCAP 100 may use either the authorized band or the unlicensed band.

[0156] In addition, the block diagram used in the description of the above embodiment ( Figure 2 、 Figure 3 ) shows blocks in functional units. These functional blocks (structural parts) are implemented by any combination of at least one of hardware and software. In addition, there is no particular limitation on the implementation method of each functional block. That is, each functional block can be implemented using a device that is physically or logically combined, or can be implemented using multiple devices by connecting two or more physically or logically separated devices directly or indirectly (for example, using wired or wireless connections). The functional block can be implemented by combining software with the above-mentioned one device or the above-mentioned multiple devices.

For example, a functional block (structural unit) that enables the transmission function is called a transmitting unit or a transmitter. In short, as described above, there is no particular limitation on the implementation method.

[0158] Furthermore, the NCAP 100 and the UE 200 described above can function as a computer that performs processing of the wireless communication method of the present disclosure. Figure 7 FIG is a diagram showing an example of the hardware configuration of NCAP 100 and UE 200.

[0159] In the following description, the word "device" can be replaced with "circuit," "device," "unit," etc. The hardware structure of the device may include one or more of the devices shown in the figures, or may exclude some of the devices.

[0160] Each functional block of NCAP 100 and UE 200 (see Figure 2 、 Figure 3 ) is implemented by any hardware element or combination of hardware elements in the computer device.

[0161] In addition, by reading predetermined software (program) into hardware such as processor 1001 and memory 1002, processor 1001 performs calculations to control the communication of communication device 1004, or controls at least one of the reading and writing of data in memory 1002 and memory 1003, thereby realizing various functions in NCAP 100 and UE 200.

[0162] The processor 1001 controls the entire computer by, for example, running an operating system. The processor 1001 may be composed of a central processing unit (CPU) including an interface with peripheral devices, a control unit, a calculation unit, registers, and the like.

[0163] In addition, the processor 1001 reads programs (program code), software modules, data, etc. from at least one of the storage device 1003 and the communication device 1004 to the memory 1002, and performs various processes accordingly. As a program, a program that causes the computer to perform at least a portion of the actions described in the above embodiments is used. Moreover, the various processes described above can be performed by one processor 1001, or by two or more processors 1001 simultaneously or sequentially. The processor 1001 can also be implemented by one or more chips. In addition, the program can also be transmitted from the network via a telecommunications line.

Storage device 1003 may also be referred to as an auxiliary storage device. The aforementioned recording medium may be, for example, a database, a server, or other appropriate medium that includes at least one of memory 1002 and storage device 1003.

[0166] The communication device 1004 is hardware (transceiver) used to communicate between computers via at least one of a wired network and a wireless network, and may also be called a network device, a network controller, a network card, a communication module, etc.

[0167] The communication device 1004 may be configured to include, for example, a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc., to implement at least one of frequency division duplex (FDD) and time division duplex (TDD).

[0168] The input device 1005 is an input device that receives input from the outside (e.g., a keyboard, mouse, microphone, switch, button, sensor, etc.). The output device 1006 is an output device that outputs to the outside (e.g., a display, speaker, LED light, etc.). Alternatively, the input device 1005 and the output device 1006 may be integrally formed (e.g., a touch panel).

[0169] Furthermore, the processor 1001, the memory 1002, and other devices are connected via a bus 1007 for communicating information. The bus 1007 may be configured as a single bus or may be configured as different buses between devices.

[0170] Furthermore, the device may be configured to include hardware such as a microprocessor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a programmable logic device (PLD), or a field-programmable gate array (FPGA), and some or all of the functional blocks may be implemented using this hardware. For example, the processor 1001 may be implemented using at least one of these hardware components.

[0171] In addition, the notification of information is not limited to the form / implementation method described in the present disclosure, and other methods may also be used. For example, the notification of information may be implemented through physical layer signaling (e.g., downlink control information (Downlink Control Information: DCI), uplink control information (Uplink Control Information: UCI), high-layer signaling (e.g., RRC signaling, medium access control (Medium Access Control: MAC) signaling, broadcast information (Master Information Block (Master Information Block: MIB), System Information Block (System Information Block: SIB)), other signals or a combination thereof. In addition, RRC signaling may also be referred to as an RRC message, for example, an RRC Connection Setup message, an RRC Connection Reconfiguration message, etc.

[0172] Each form / embodiment described in the present disclosure can also be applied to a mobile communication system using Long Term Evolution (LTE), LTE-Advanced (LTE-A), Super 3G (SUPER 3), IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 6th generation mobile communication system (6G), xth generation mobile communication system (xG) (x is an integer or a decimal), Future Radio Access (FRA), New Radio (NR), W-CDMA (registered trademark), GSM (registered trademark), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE At least one of IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra Wideband (UWB), Bluetooth (registered trademark), other appropriate systems, and next-generation systems that are expanded upon these systems. Furthermore, a combination of multiple systems (for example, a combination of at least one of LTE and LTE-A with 5G, etc.) may also be employed.

[0173] The processing steps, sequences, and flows of each form / implementation described in this disclosure may be reordered unless there is a conflict. For example, the methods described in this disclosure use an illustrative order to present the elements of various steps, but are not limited to the specific order presented.

[0174] In this disclosure, specific actions performed by a base station may also be performed by its upper node, depending on the circumstances. In a network consisting of one or more network nodes including a base station, various actions performed to communicate with a terminal can be performed by at least one of the base station and other network nodes other than the base station (e.g., an MME or S-GW, but not limited thereto). While the above example illustrates a single other network node other than the base station, it may also be a combination of multiple other network nodes (e.g., an MME and an S-GW).

[0175] Information, signals (information, etc.) can be output from a higher layer (or lower layer) to a lower layer (or higher layer), or can be input or output via multiple network nodes.

[0176] Input and output information can be stored in a specific location (e.g., memory) or managed using a management table. Input and output information can be overwritten, updated, or appended. Output information can also be deleted. Input information can also be sent to other devices.

[0177] The determination may be made using a value represented by one bit (0 or 1), a Boolean value (Boolean: true or false), or a comparison of numerical values ​​(for example, comparison with a predetermined value).

[0178] Each form / implementation described in this disclosure may be used individually or in combination, and may be switched between them depending on the execution. Furthermore, notification of scheduled information is not limited to being performed explicitly (e.g., a notification of "yes X") but may also be performed implicitly (e.g., not notifying the scheduled information).

[0179] Software, whether referred to as software, firmware, middleware, microcode, hardware description language, or by other names, shall be interpreted broadly to refer to instructions, sets of instructions, code, code segments, program code, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions, etc.

[0180] Additionally, software, commands, information, and the like may be sent and received via a transmission medium. For example, if software is transmitted from a website, server, or other remote source using at least one of a wired technology (coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL), etc.) and a wireless technology (infrared, microwave, etc.), at least one of these wired and wireless technologies is included within the definition of a transmission medium.

[0181] The information, signals, etc. described in this disclosure may also be represented using any of a variety of different technologies. For example, data, commands, instructions, information, signals, bits, symbols, chips, etc. that may be referred to in the entire description may also be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or photons, or any combination thereof.

[0182] In addition, the terms used in this disclosure and those required for understanding this disclosure may be replaced with terms having the same or similar meanings. For example, at least one of a channel and a symbol may be a signal (signaling). Furthermore, a signal may be a message. Furthermore, a component carrier (CC) may also be referred to as a carrier frequency, a cell, a frequency carrier, etc.

[0183] As used in this disclosure, the terms "system" and "network" are used interchangeably.

[0184] In addition, the information, parameters, etc. described in this disclosure can be expressed using absolute values, relative values ​​relative to predetermined values, or other corresponding information. For example, wireless resources can also be indicated using indexes.

[0185] The names used for the above parameters are non-limiting in any respect. Furthermore, the formulas and the like using these parameters may sometimes differ from those explicitly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by any appropriate names, and the names assigned to these channels and information elements are non-limiting in any respect.

[0186] In this disclosure, terms such as "base station (BS)", "wireless base station", "fixed station", "NodeB", "eNodeB (eNB)", "gNodeB (gNB)", "access point", "transmission point", "reception point", "transmission / reception point", "cell", "sector", "cell group", "carrier", and "component carrier" are used interchangeably. Base stations are also sometimes referred to as macrocells, small cells, femtocells, and picocells.

[0187] A base station can accommodate one or more (for example, three) cells (also called sectors). When a base station accommodates multiple cells, the base station's overall coverage area can be divided into multiple smaller areas, each of which can also provide communication services through a base station subsystem (for example, a small base station (Remote Radio Head: RRH)) for indoor use.

[0188] The terms "cell" or "sector" refer to a portion or the entire coverage area of ​​at least one of a base station and a base station subsystem that provides communication services within the coverage area.

[0189] In the present disclosure, the base station sending information to the terminal may also be replaced by the base station instructing the terminal to perform a control / action based on the information.

[0190] In the present disclosure, terms such as “mobile station (MS)”, “user terminal (user terminal)”, “user equipment (UE)”, and “terminal” may be used interchangeably.

[0191] For mobile stations, those skilled in the art sometimes also use the following terms to refer to them: subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or some other appropriate terms.

[0192] At least one of the base station and the mobile station may also be referred to as a transmitting device, a receiving device, a communication device, etc. In addition, at least one of the base station and the mobile station may also be a device mounted on a mobile body, the mobile body itself, etc. The mobile body may be a means of transportation (for example, a car, an airplane, etc.), a mobile body that moves unmanned (for example, a drone, an autonomous vehicle, etc.), or a robot (manned or unmanned). In addition, at least one of the base station and the mobile station also includes a device that does not necessarily move during communication operations. For example, at least one of the base station and the mobile station may be an IoT (Internet of Things) device such as a sensor.

[0193] In addition, the base station in the present disclosure can also be replaced by a mobile station (user terminal, the same below). For example, regarding a structure in which the communication between a base station and a mobile station is replaced by communication between multiple mobile stations (for example, it can also be called D2D (Device-to-Device: device to device), V2X (Vehicle-to-Everything: vehicle to everything system), etc.), the various forms / implementations of the present disclosure can also be applied. In this case, it is also possible to set a structure in which the mobile station has the functions of the base station. In addition, terms such as "uplink" and "downlink" can also be replaced by terms corresponding to communication between terminals (for example, "side"). For example, uplink channels, downlink channels, etc. can be replaced with side channels (or side links).

[0194] Likewise, the mobile station in the present disclosure may be replaced by a base station. In this case, the base station may have the same functions as the mobile station.

[0195] A radio frame can be composed of one or more frames in the time domain. In the time domain, one or more frames can be called a subframe. A subframe can also be composed of one or more time slots in the time domain. A subframe can be a fixed time length (e.g., 1 ms) that is independent of the numerology.

[0196] A parameter set may be a communication parameter applied to at least one of the transmission and reception of a signal or channel. For example, the parameter set may represent at least one of the following: subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame structure, specific filtering performed by the transceiver in the frequency domain, specific windowing performed by the transceiver in the time domain, and the like.

[0197] A slot may be composed of one or more symbols (OFDM (Orthogonal Frequency Division Multiplexing) symbols, SC-FDMA (Single Carrier Frequency Division Multiple Access) symbols, etc.) in the time domain. A slot may be a time unit based on a parameter set.

[0198] A time slot may contain multiple mini-slots. Each mini-slot may consist of one or more symbols in the time domain. Furthermore, a mini-slot may also be referred to as a sub-slot. A mini-slot may consist of fewer symbols than a time slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a mini-slot may also be referred to as PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot may also be referred to as PDSCH (or PUSCH) mapping type B.

[0199] Radio frame, subframe, time slot, mini-time slot, and symbol all represent time units for signal transmission. Radio frame, subframe, time slot, mini-time slot, and symbol may be referred to by other corresponding names.

[0200] For example, a subframe can be called a transmission time interval (TTI), multiple consecutive subframes can be called a TTI, and a slot or mini-slot can be called a TTI. That is, at least one of a subframe and a TTI can be a subframe (1ms) in existing LTE, a period shorter than 1ms (e.g., 1-13 symbols), or a period longer than 1ms. Furthermore, the unit representing a TTI can be called a slot, a mini-slot, or the like, rather than a subframe.

[0201] Here, TTI refers to, for example, the minimum time unit for scheduling in wireless communications. For example, in the LTE system, a base station schedules the allocation of radio resources (such as the frequency bandwidth and transmit power available to each user terminal) to each user terminal using TTIs. The definition of TTI is not limited to this.

[0202] A TTI can be a unit of time for transmitting data packets (transport blocks), code blocks, code words, etc. after channel coding, or a unit of processing such as scheduling and link adaptation. Furthermore, when a TTI is given, the time interval (e.g., the number of symbols) to which a transport block, code block, code word, etc. is actually mapped can be shorter than the TTI.

[0203] In addition, when a time slot or a mini-time slot is called a TTI, one or more TTIs (i.e., one or more time slots or one or more mini-time slots) can become the minimum time unit for scheduling. In addition, the number of time slots (mini-time slots) that constitute the minimum time unit for scheduling can also be controlled.

[0204] A TTI with a time length of 1 ms is also called a normal TTI (TTI in LTE Rel. 8-12), a normal TTI, a long TTI, a normal subframe, a normal subframe, a long subframe, a time slot, etc. A TTI shorter than a normal TTI may also be called a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a minislot, a subslot, a time slot, etc.

[0205] In addition, for long TTI (for example, normal TTI, subframe, etc.), it can be understood as a TTI with a time length of more than 1ms, and for short TTI (for example, shortened TTI, etc.), it can be understood as a TTI with a TTI length smaller than long TTI (long TTI) and greater than 1ms.

[0206] A resource block (RB) is a unit of resource allocation in the time and frequency domains. In the frequency domain, it can contain one or more consecutive subcarriers. The number of subcarriers contained in an RB can be the same regardless of the parameter set, for example, it can be 12. The number of subcarriers contained in an RB can also be determined by the parameter set.

[0207] In addition, the time domain of an RB may include one or more symbols, or may be the length of a slot, a mini-slot, a subframe, or a TTI. A TTI, a subframe, etc. may also be composed of one or more resource blocks.

[0208] In addition, one or more RBs may also be referred to as a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, and the like.

[0209] Furthermore, a resource block may be composed of one or more resource elements (REs). For example, one RE may be a radio resource region of one subcarrier and one symbol.

[0210] A Bandwidth Part (BWP) (also referred to as a fractional bandwidth) represents a subset of contiguous common resource blocks (RBs) used for a particular parameter set within a carrier. Common RBs can be identified by their index relative to the common reference point for that carrier. PRBs can be defined within a BWP and numbered within that BWP.

[0211] The BWP may include a BWP for UL (UL BWP) and a BWP for DL ​​(DL BWP). One or more BWPs may be configured for a UE within one carrier.

[0212] At least one of the configured BWPs may be active, and it is not assumed that the UE transmits or receives predetermined signals / channels outside of the activated BWP. In addition, "cell", "carrier", etc. in the present disclosure may be replaced with "BWP".

[0213] The above-described structures of radio frames, subframes, slots, mini-slots, and symbols are merely examples. For example, various modifications may be made to the structures, such as the number of subframes in a radio frame, the number of slots per subframe or radio frame, the number of mini-slots within a slot, the number of symbols and RBs within a slot or mini-slot, the number of subcarriers within an RB, the number of symbols within a TTI, the symbol length, and the cyclic prefix (CP) length.

[0214] The terms "connected", "coupled" or all variations of these terms are intended to indicate any direct or indirect connection or combination between two or more elements, and may include situations where there is one or more intermediate elements between two elements that are "connected" or "coupled" to each other. The combination or connection between elements may be a physical combination or connection, a logical combination or connection, or a combination of these. For example, "access" may be used instead of "connection". As used in this disclosure, two elements may be considered to be "connected" or "coupled" to each other using at least one of one or more wires, cables and printed electrical connections, and as some non-limiting and non-inclusive examples, electromagnetic energy having wavelengths in the wireless frequency domain, microwave region and light (including both visible and invisible) region may be used to "connect" or "couple" to each other.

[0215] The reference signal may be referred to as Reference Signal (RS) for short, or may be referred to as a pilot signal depending on the applicable standard.

[0216] The phrase “based on” used in this disclosure does not mean “based only on” unless explicitly stated otherwise. In other words, the phrase “based on” means both “based only on” and “based at least on.”

[0217] The “unit” in the configuration of each of the above-mentioned devices may be replaced with a “section,” “circuit,” “device,” or the like.

[0218] Any reference to an element using the designations "first," "second," etc., as used in this disclosure, does not necessarily define the number or order of these elements. These designations may be used in this disclosure as a convenient way to distinguish between two or more elements. Therefore, reference to a first and a second element does not mean that only two elements can be used there, or that the first element must precede the second element in some form.

[0219] When the terms "include," "including," and variations thereof are used in this disclosure, these terms, like the term "comprising," are intended to be inclusive. Furthermore, the term "or" used in this disclosure does not mean an exclusive or.

[0220] In the present disclosure, when an article is added by translation, such as a, an, and the in English, the present disclosure also includes cases where the noun following the article is in a plural form.

[0221] As used in this disclosure, terms such as "determining" and "determining" sometimes encompass a variety of actions. For example, "determining" and "judging" may include situations where judging, calculating, computing, processing, deriving, investigating, looking up, searching, inquiring (e.g., searching in a table, database, or other data structure), and ascertaining are considered "determining" and "determining." Furthermore, "determining" and "receiving" (e.g., receiving information), transmitting (e.g., sending information), inputting, outputting, and accessing (e.g., accessing data in a memory) are considered "determining" and "determining." Furthermore, "determining" and "resolving" may include situations where selecting, choosing, establishing, and comparing are considered "determining" and "determining." That is, "judgment" and "decision" can include situations where certain actions are considered to have been "judged" or "decided." In addition, "judgment (decision)" can also be replaced by "assuming (assuming)", "expecting (expecting)", "considering (considering)", etc.

[0222] In this disclosure, the phrase "A and B are different" can mean "A and B are different from each other." Alternatively, the phrase can mean "A and B are each different from C." Terms such as "separate" and "bound" can also be interpreted in the same way as "different."

[0223] While the present disclosure has been described in detail above, it should be clear to those skilled in the art that the present disclosure is not limited to the embodiments described herein. The present disclosure can be implemented in various modifications and variations without departing from the spirit and scope of the present disclosure as defined by the claims. Therefore, the description of the present disclosure is for illustrative purposes only and is not intended to limit the present disclosure in any way.

[0224] Figure 8 2001 shows a structural example of a vehicle. Figure 8As shown, the vehicle 2001 has a drive unit 2002, a steering unit 2003, an accelerator pedal 2004, a brake pedal 2005, a gear lever 2006, left and right front wheels 2007, left and right rear wheels 2008, an axle 2009, an electronic control unit 2010, various sensors 2021 to 2029, an information service unit 2012 and a communication module 2013.

Information service unit 2012 uses information obtained from external devices via communication module 2013 and the like to provide various multimedia information and services to vehicle 1 passengers.

[0228] The information service unit 2012 may include input devices for receiving input from the outside (such as keyboard, mouse, microphone, switch, button, sensor, touch panel, etc.), and may also include output devices for implementing output to the outside (such as display, speaker, LED light, touch panel, etc.).

[0229] The driving assistance system unit 2030 is composed of various devices that provide functions for preventing accidents or reducing the driver's driving load, such as millimeter-wave radar, LiDAR (Light Detection and Ranging), cameras, positioning devices (such as GNSS), map information (such as high-definition (HD) maps, autonomous vehicle (AV) maps, etc.), gyroscope systems (such as IMU (Inertial Measurement Unit), INS (Inertial Navigation System), etc.), AI (Artificial Intelligence) chips, AI processors, and one or more ECUs that control these devices. In addition, the driving assistance system unit 2030 sends and receives various information via the communication module 2013 to implement driving assistance functions or autonomous driving functions.

[0230] The communication module 2013 can communicate with the microprocessor 2031 and components of the vehicle 1 via the communication port. For example, the communication module 2013 can transmit and receive data via the communication port 2033 with the drive unit 2002, steering unit 2003, accelerator pedal 2004, brake pedal 2005, shift lever 2006, left and right front wheels 2007, left and right rear wheels 2008, axle 2009, the microprocessor 2031 in the electronic control unit 2010, the memory (ROM, RAM) 2032, and the sensors 2021 to 2028 included in the vehicle 2001.

[0231] The communication module 2013 is controlled by the microprocessor 2031 of the electronic control unit 2010 and is a communication device capable of communicating with external devices. For example, various information can be transmitted and received with the external device via wireless communication. The communication module 2013 can be located inside or outside the electronic control unit 2010. The external device can also be, for example, a base station or a mobile station.
