[0027] (System Structure)

[0028] Figure 1 It is a diagram for explaining a wireless communication system according to an embodiment of the present invention.

[0029] like Figure 1 As shown, the wireless communication system in the embodiment of the present invention includes a base station 10 and a terminal 20. Figure 1 In the figure, one base station 10 and one terminal 20 are shown, but this is an example and a plurality of base stations 10 and a plurality of terminals 20 may be provided.

[0030] The base station 10 is a communication device that provides one or more cells and performs wireless communication with the terminal 20. The physical resources of the wireless signal are defined in the time domain and the frequency domain. The time domain can be defined by the number of OFDM (Orthogonal Frequency Division Multiplexing) symbols, and the frequency domain can be defined by the number of subcarriers or resource blocks. In addition, the TTI (Transmission Time Interval) in the time domain can be a time slot, and the TTI can also be a subframe.

[0031] The base station 10 sends a synchronization signal and system information to the terminal 20. The synchronization signal is, for example, NR-PSS and NR-SSS. The system information is, for example, sent via NR-PBCH, also known as broadcast information. The synchronization signal and system information may also be referred to as SSB (SS / PBCH block). Figure 1As shown, the base station 10 sends a control signal or data to the terminal 20 via DL (Downlink), and receives a control signal or data from the terminal 20 via UL (Uplink). Both the base station 10 and the terminal 20 can perform beamforming to send and receive signals. In addition, both the base station 10 and the terminal 20 can apply MIMO (Multiple Input Multiple Output)-based communications to DL or UL. In addition, the base station 10 and the terminal 20 can also communicate via a secondary cell (SCell: Secondary Cell) and a primary cell (PCell: Primary Cell) based on CA (Carrier Aggregation). Furthermore, the terminal 20 can also communicate via the primary cell of the base station 10 based on DC (Dual Connectivity) and the primary and secondary cell group cells (PSCell: Primary SCG Cell) of other base stations 10.

[0032] The terminal 20 is a communication device having a wireless communication function, such as a smart phone, a mobile phone, a tablet computer, a wearable terminal, or an M2M (Machine-to-Machine) communication module. Figure 1 As shown, the terminal 20 receives a control signal or data from the base station 10 via DL and sends a control signal or data to the base station 10 via UL, thereby utilizing various communication services provided by the wireless communication system. In addition, the terminal 20 receives various reference signals sent from the base station 10 and performs a measurement of the propagation path quality based on the reception result of the reference signal. In addition, the terminal 20 may also be referred to as a UE and the base station 10 may be referred to as a gNB.

[0033] Figure 2 1 is a diagram showing an example of a configuration of a wireless communication system according to an embodiment of the present invention. The wireless communication system includes a RAN 10 , a terminal 20 , a core network 30 , and a DN (Data Network) 40 .

[0034] The core network 30 is a network including switches, a subscriber information management device, etc. The core network 30 includes a network node group that realizes the U-Plane function and a network node group that realizes the C-Plane function group.

[0035] The U-Plane function is a function for executing the sending and receiving processing of user data. A network node that implements the U-Plane function is, for example, UPF (User plane function) 380. UPF 380 is a network node having functions such as an external PDU (Protocol Data Unit) session point for interconnection with DN 40, routing and forwarding of packets, and QoS (Quality of Service) processing of the user plane. UPF 380 controls the sending and receiving of data between DN 40 and terminal 20. UPF 380 and DN 40 can be composed of one or more network slices.

[0036] The C-Plane function group is a function group that performs a series of control processes for communication establishment, etc. The network node group that realizes the C-Plane function group includes, for example, AMF (Access and Mobility Management Function) 310, UDM (Unified Data Management) 320, NEF (Network Exposure Function) 330, NRF (Network Repository Function) 340, AUSF (Authentication Server Function) 350, PCF (Policy Control Function) 360, SMF (Session Management Function) 370, and AF (Application Function) 390.

[0037] The RAN 10 is connected in a communicable manner between the core network 30 and the terminal 20, and is a network node including a base station, a line control device, etc. The RAN 10 is connected in a communicable manner with the AMF 310 and the UPF 380. In addition, the base station 10 is also referred to as the RAN 10 below.

[0038] AMF 310 is a network node having functions such as termination of RAN interface, termination of NAS (Non-Access Stratum), registration management, connection management, reachability management, mobility management, etc. NRF 340 is a network node having a function of discovering NF (Network Function) instances that provide services. UDM 320 is a network node that manages subscriber data and authentication data. UDM 320 includes UDR (User Data Repository) 321 and FE (Front End) 322 that maintain the data. FE 322 processes subscriber information.

[0039] SMF 370 is a network node with functions such as session management, IP (Internet Protocol) address allocation and management of terminal 20, DHCP (Dynamic Host Configuration Protocol) function, ARP (Address Resolution Protocol) proxy, roaming function, etc. NEF 330 is a network node with the function of notifying other NFs (Network Functions) of capabilities and events. PCF 360 is a network node with the function of performing policy control of the network.

[0040] AF (Application Function) 390 is a network node having a function of controlling an application server.

[0041] The terminal 20 and the AMF 310 are connected as an N1 link in a manner that allows communication. The AMF 310 and the RAN 10 are connected as an N2 link in a manner that allows communication. The UPF 380 and the RAN 10 are connected as an N3 link in a manner that allows communication. The UPF 380 and the SMF 370 are connected as an N4 link in a manner that allows communication. The UPF 380 and the DN 40 are connected as an N6 link in a manner that allows communication.

[0042] Furthermore, the core network 30 of the present embodiment includes a CRMF (Computing Resource Management Function) 371 and a UCRF (User Computing Resource Function) 381 in addition to the above-mentioned conventional configuration.

[0043] UCRF 381 is a function of providing computing resources that can be used by users (subscribers) (hereinafter also referred to as user computing resource function). Hereinafter, computing resources will also be referred to as containers. In addition, computing resources may also include an execution environment for executing various applications installed on the computing resources. That is, UCRF 381 has one or more containers 382. UCRF381 is included in the U-Plane function and is connected to UPF 380 as an Ny link in a manner that allows communication. There is also a case where UCRF 381 is connected to RAN 10 as an N3 link in a manner that allows communication. In addition, UCRF 381 is connected to DN 40 as an N6 link in a manner that allows communication.

[0044] CRMF 371 is a function for managing computing resources (hereinafter also referred to as computing resource management function). CRMF 371 is included in the C-Plane functional group and is connected to other network nodes included in the C-Plane functional group in a communicable manner.

[0045] The CRMF 371 and the UCRF 381 are connected to each other as an Nx link so as to be able to communicate with each other. The names of the Nx link and the Ny link are just examples, and other names may be used.

[0046] (Past Problems)

[0047] Here, the problems of the prior art are explained. In 6G, the following use cases are being studied. (i) Communication operators are able to lend computing resources (e.g., container 382) within the network, the execution environment contained in the computing resources, and applications that operate on the execution environment to subscribers. (ii) Subscribers are able to use applications as endpoints for outgoing / incoming calls related to themselves. (iii) The computing resources / execution environment / applications act as pseudo-terminals and operate independently of the subscriber's normal terminals.

[0048] As described above, the pseudo terminal and the normal terminal generally operate independently, but there are also cases where they work closely together. For example, consider the following cases: (a) before communicating with the outside, the pseudo terminal requests permission to start communication from the normal terminal and the subscriber operating the normal terminal; (b) when the pseudo terminal sends data to the normal terminal during communication with the outside; (c) when the normal terminal gives instructions to the pseudo terminal.

[0049] In the past, the communication between the normal terminal and the pseudo terminal passed through N6, which caused security concerns. A PDU session establishment process in which the normal terminal communicates directly with the pseudo terminal without passing through N6, especially a mechanism for discovering the connection target of the PDU session, is required.

[0050] (Overview of this embodiment)

[0051] Therefore, in this embodiment, the processing of the case where the AMF 310 receives the UL-NAS transmission containing the newly defined information (i.e., the request type = the initial request for setting the existing container communication path, and the CRMF session ID) is introduced. In addition, when the PDU session is established, the CRMF 371 acts in the same way as the SMF 370 for the terminal 20 and the RAN 10.

[0052] Figure 3 1 is a sequence diagram showing an example of the flow of the CRMF session establishment process according to the embodiment of the present invention. The terminal 20 allocates a CRMF session ID by itself and stores the CRMF session ID.

[0053] In step S101, the terminal 20 sends a CRMF session establishment request to the AMF 310. Specifically, the terminal 20 sends a UL-NAS transmission including a container management request type = initial request and a CRMF session ID to the AMF 310. The UL-NAS transmission includes the CRMF session establishment request, and the CRMF session establishment request includes the CRMF session ID.

[0054] In the next step S102, AMF 310 sends a CRMF session establishment request to CRMF 371. AMF 310 includes in the CRMF session establishment request the CRMF session ID set by the terminal 20. The CRMF session establishment request may specifically be a Ncrmf_CRMFSession_CreateCRMContext request including the CRMF session establishment request.

[0055] The AMF 310 understands that a new container is set based on the information included in the UL-NAS transmission, and newly selects the CRMF 371. The AMF 310 stores the CRMF session ID and information indicating the selected CRMF 371.

[0056] In the next step S103, CRMF 371 sends a subscriber information confirmation to UDM 320 in order to obtain subscriber information. In the next step S104, UDM 320 sends a subscriber information response to CRMF 371. CRMF 371 determines whether to allow the CRMF session establishment request from the terminal 20 based on the obtained subscriber information. In the case where the CRMF session establishment request from the terminal 20 is allowed by the determination, the process may proceed to step S105. On the other hand, in the case where the CRMF session establishment request from the terminal 20 is not allowed by the determination, CRMF 371 may send a response indicating that the CRMF session establishment request is rejected to AMF 310. AMF 310 may send the response to the terminal 20.

[0057] In the next step S105, CRMF 371 sends the requested resource capability capacity obtained through the CRMF session establishment request to PCF 360. In the next step S106, PCF 360 determines the capacity of computing resources provided to Terminal 20 based on the information included in the obtained requested resource capability capacity and the policy of the communication operator, and sends information including the determined capacity to CRMF 371 as a requested resource capability response.

[0058] For example, PCF 360 may decide to provide terminal 20 with computing resources of the same capacity as the requested resource capacity, or may decide to provide terminal 20 with computing resources less than the requested resource capacity, or may decide to provide terminal 20 with computing resources greater than the requested resource capacity.

[0059] In the next step S107, CRMF 371 selects UCRF 381. For example, CRMF 371 may select UCRF 381 close to terminal 20 based on the location information of terminal 20. In the next step S108, CRMF 371 sends a UCRF session establishment request to UCRF 381. CRMF 371 sets a computing resource generation request in the UCRF session establishment request. The computing resource generation request may be set based on the requested resource capability capacity, and may include information indicating the capacity of the computing resource based on the requested resource capability response obtained from PCF 360. The UCRF session establishment request may include a container setting request.

[0060] In the next step S109, UCRF 381 sets a container. The container may be set based on the capacity of the computing resources obtained from CRMF 371. In the next step S110, UCRF 381 sends a UCRF session establishment response to CRMF 371. The UCRF session establishment response may include a notification of completion of setting of the container.

[0061] In the next step S111, the CRMF 371 sends a CRMF session establishment response to the AMF 310. The CRMF session establishment response may be a Namf_Communication_N1N2MessageTransfer.

[0062] In the next step S112, the AMF 310 sends a CRMF session establishment response to the terminal 20.

[0063] In step S113, UCRF 381 may obtain an external communication IP address from, for example, an interface with DN. In step S114, UCRF 381 may start an application in the container. The application may be a communication application that uses the obtained external communication IP address.

[0064] In addition, after step S114 , the terminal 20 may also use the container set in the UCRF 381 to receive the service of the communication carrier.

[0065] Next, the procedure for setting a communication path from the terminal 20 to the container 382 will be described.

[0066] Figure 4 This is a sequence diagram showing an example of the flow of the communication path setting process according to the embodiment of the present invention. The terminal 20 allocates a PDU session ID by itself. The terminal 20 stores the PDU session ID.

[0067] Next, the terminal 20 sends a PDU session establishment request (UL-NAS transmission including the PDU session establishment request) to the AMF 310 (step S201). The PDU session establishment request may include request type = existing container communication path setup initial request, CRMF session ID and PDU session ID. The UL-NAS transmission may include CRMF session ID, PDU session ID and PDU session establishment request.

[0068] The AMF 310 understands that a communication path is set for the existing container based on the information included in the UL-NAS transmission, and identifies the CRMF 371 storing the existing container based on the CRMF session ID included in the UL-NAS transmission (step S202).

[0069] Then, the AMF 310 sends a PDU session establishment request to the CRMF 371 (step S203). The PDU session establishment request sent may specifically be a Ncrmf_CRMFSession_UpdateCRMContext request including the PDU session establishment request. The Ncrmf_CRMFSession_UpdateCRMContext request may be a request to update the computing resource management information corresponding to the established CRMF session, and a request to set the communication path with the container 382.

[0070] The CRMF 371 requests the UCRF 381 and the container 382 corresponding to the CRMF session ID for allocation of a termination point toward the RAN (step S204).

[0071] The UCRF 381 allocates a termination point toward the RAN, and notifies the CRMF 371 of information indicating the allocated termination point toward the RAN (step S205).

[0072] CRMF 371 sends information indicating the allocated RAN-facing termination point to AMF 310 (step S206). The information indicating the RAN-facing termination point may be Namf_Communication_N1N2MessageTransfer including a PDU Session Resource Setup Request Transfer including the information indicating the RAN-facing termination point.

[0073] The AMF 310 sends a PDU session resource setup request (PDU SessionResource SetupRequest) to the RAN 10 (step S207). The PDU session resource setup request may include a PDU session resource setup request transfer (PDU SessionResource Setup Request Transfer).

[0074] RAN 10 sets the termination information for RAN (step S208). RAN 10 sends a PDU Session Resource Setup Response to AMF 310 (step S209). The PDU Session Resource Setup Response may include a PDU Session Resource Setup Response Transfer, which includes the termination information for UCRF.

[0075] Next, AMF 310 sends a CRM information update request to CRMF 371 (step S210). The CRM information update request may be Ncrmf_CRMFSession_UpdateCRMContext including a PDU Session Resource Setup Response Transfer. The CRM information update request is a request to update CRM information. In addition, the CRM information may be information for managing computing resources.

[0076] The CRMF 371 sets a termination point toward the UCRF 381 in the UCRF 381 and the container 382 (step S211).

[0077] Through the above-mentioned communication path setting process, the communication path is set between the terminal 20 and the container 382. As a result, secure communication can be achieved between the computing resources on the network and the terminal.

[0078] The above CRMF session establishment process can be performed when a PDU session has already been established. In this case, in step S101, the terminal 20 can send a UL-NAS transmission including a container management request type = existing PDU session container setup initial request, the PDU session ID of the existing PDU session, and the CRMF session ID to the AMF 310. As a result, the existing PDU session can be used to communicate with the newly set container 382.

[0079] (Device Structure)

[0080] Next, the functional configuration examples of the base station 10, the terminal 20, and various network nodes that implement the above-described processing and actions are described.

In addition, a network node having multiple different functions in the system architecture can be composed of multiple network nodes separated by function.

[0083] The transmitter 110 includes a function of generating a signal to be sent to the terminal 20 or other network nodes and transmitting the signal by wire or wirelessly. The receiver 120 includes a function of receiving various signals sent from the terminal 20 or other network nodes and obtaining, for example, higher layer information from the received signals.

[0084] The setting unit 130 stores in a storage device the setting information set in advance and various setting information to be transmitted to the terminal 20, and reads out from the storage device as needed. The content of the setting information is, for example, setting related to communication using the NTN.

Figure 6 As shown, the terminal 20 includes a transmitting unit 210 , a receiving unit 220 , a setting unit 230 , and a control unit 240 . Figure 6 The functional structure shown is only an example.

The USIM installed in the terminal 20 can also have a transmitting unit 210, a receiving unit 220, a setting unit 230 and a control unit 240 in the same manner as the terminal 20.

[0088] The transmitting unit 210 generates a transmission signal according to the transmission data and transmits the transmission signal wirelessly. The receiving unit 220 receives various signals wirelessly and obtains a higher layer signal from the received physical layer signal. In addition, the receiving unit 220 has a function of receiving NR-PSS, NR-SSS, NR-PBCH, DL / UL control signal or reference signal, etc. sent from the network node.

[0089] The setting unit 230 stores various setting information received from the network node by the receiving unit 220 in a storage device, and reads it from the storage device as needed. In addition, the setting unit 230 also stores pre-set setting information.

The boundaries of the functional units or processing units in the functional block diagram do not necessarily correspond to the boundaries of the physical components. The actions of multiple functional units can be performed by one physical component, or the actions of one functional unit can be performed by multiple physical components. Regarding the processing process described in the embodiment, the order of processing can be swapped without contradiction.

For example, the methods described in this disclosure use the order in which the elements of various steps are presented, but are not limited to the specific order presented.

[0147] In this specification, specific actions performed by the base station 10 are sometimes also performed by its upper node according to the situation. In a network composed of one or more network nodes having the base station 10, various actions performed for communicating with the terminal 20 can be performed by at least one of the base station 10 and other network nodes other than the base station 10 (for example, MME or S-GW, etc., but not limited to these). In the above, the case where there is one other network node other than the base station 10 is illustrated, but the other network node may also be a combination of multiple other network nodes (for example, MME and S-GW).

[0148] The information or signals described in the present disclosure can be output from a higher layer (or a lower layer) to a lower layer (or a higher layer), and can also be input or output via a plurality of network nodes.

[0149] The input or output information can be stored in a specific location (e.g., a memory) or managed using a management table. The input or output information can be rewritten, updated, or appended. The output information can also be deleted. The input information can also be sent to other devices.

[0150] The determination in the present disclosure may be performed by a value represented by 1 bit (0 or 1), by a Boolean value (Boolean: true or false), or by comparison of numerical values ​​(for example, comparison with a predetermined value).

[0151] Software, whether referred to as software, firmware, middleware, microcode, hardware description language, or by other names, shall be interpreted broadly to refer to commands, sets of commands, codes, code segments, program codes, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions, etc.

[0152] In addition, software, commands, information, etc. may be sent and received via a transmission medium. For example, when software is sent from a web page, server, or other remote source using at least one of wired technology (coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), etc.) and wireless technology (infrared, microwave, etc.), at least one of these wired technology and wireless technology is included in the definition of transmission medium.

[0154] In addition, the terms described in the present disclosure and the terms required for understanding the present disclosure may be replaced with terms having the same or similar meanings. For example, at least one of a channel and a symbol may also be a signal (signaling). In addition, a signal may also be a message. In addition, a component carrier (CC) may also be referred to as a carrier frequency, a cell, a frequency carrier, etc.

[0156] In addition, the information, parameters, etc. described in the present disclosure may be represented by absolute values, relative values ​​to predetermined values, or other corresponding information. For example, a wireless resource may be indicated by an index.

[0157] The names used for the above parameters are non-restrictive in any respect. Furthermore, the formulas etc. using these parameters may sometimes differ from those explicitly disclosed in the present disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by all appropriate names, and therefore the various names assigned to these various channels and information elements are non-restrictive in any respect.

[0158] In the present disclosure, the terms "base station (BS)," "wireless base station", "base station", "fixed station", "NodeB", "eNodeB (eNB)", "gNodeB (gNB)", "access point", "transmission point", "reception point", "transmission / reception point", "cell", "sector", "cell group", "carrier", "component carrier" and the like are used interchangeably. Sometimes, the base station is also referred to as macro cell, small cell, micro-micro cell, micro-micro cell and the like.

[0159] A base station can accommodate one or more (for example, 3) cells. When a base station accommodates multiple cells, the overall coverage area of ​​the base station can be divided into multiple smaller areas, and each smaller area can also provide communication services through a base station subsystem (for example, a small base station for indoor use (RRH: Remote Radio Head)). Terms such as "cell" or "sector" refer to a part or the entirety of the coverage area of ​​at least one of a base station and a base station subsystem that provide communication services within the coverage area.

[0160] In the present disclosure, the base station sending information to the terminal may be replaced by the base station instructing the terminal to perform control / action based on the information.

[0161] In the present disclosure, terms such as “mobile station (MS)”, “user terminal (user terminal)”, “user equipment (UE)”, and “terminal” may be used interchangeably.

In addition, of course, it also includes the situation where the mobile body stops. The mobile body includes, for example, vehicles, transport vehicles, cars, motorcycles, bicycles, networked cars, excavators, bulldozers, wheel loaders, dump trucks, forklifts, trains, buses, two-wheel trailers (rear car), rickshaws, ships (ships and other watercraft: ships and other ships), airplanes, rockets, artificial satellites, Drone (registered trademark), multi-rotor helicopters, quadcopters, balloons and objects mounted on them, and is not limited to this.

It can be a means of transportation (such as a car, an airplane, etc.), a mobile body that moves in an unmanned manner (such as a drone, an automatic driving car, etc.), or a robot (man-powered 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.

[0164] In addition, the base station in the present disclosure may also be replaced by a user terminal. For example, a structure in which the communication between a base station and a user terminal is replaced by the communication between multiple terminals 20 (for example, it may also be referred to as D2D (Device-to-Device), V2X (Vehicle-to-Everything), etc.) may also apply various forms / implementations of the present disclosure. In this case, it may also be configured that the terminal 20 has the functions possessed by the above-mentioned base station 10. In addition, terms such as "uplink" and "downlink" may also be replaced by terms corresponding to communication between terminals (for example, "side"). For example, uplink channels, downlink channels, etc. may also be replaced by side channels.

[0165] Likewise, the user terminal in the present disclosure may be replaced by a base station. In this case, the base station may have the functions of the user terminal.

[0166] The terms "determining" and "determining" used in this disclosure sometimes include a variety of actions. "Determining" and "determining" may include, for example, considering matters that have been judged, calculated, calculated, processed, derived, investigated, searched (for example, searched in a table, database or other data structure), confirmed (ascertaining) as matters that have been "determined" or "determined", etc. In addition, "determining" and "determining" may include matters that have been received (for example, receiving information), transmitted (for example, transmitting information), input, output, accessed (for example, accessed data in memory) as matters that have been "determined" or "determined", etc. In addition, "determining" and "determining" may include matters that have been resolved (resolving), selected (selecting), chosen (choosing), established (establishing), compared (comparing), etc. as matters that have been "determined" or "determined". That is, "judgment" and "decision" may include certain actions that are considered to be "judged" or "decided". In addition, "judgment (decision)" may also be replaced by "assuming", "expecting", "considering", etc.

[0167] 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 the situation 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 to replace "connection". In the context of the present 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.

[0168] The reference signal may be referred to as RS (Reference Signal) for short, or may be referred to as a pilot signal (Pilot) according to the applied standard.

[0169] The phrase “based on” used in the present disclosure does not mean “based only on” unless otherwise explicitly stated. In other words, the phrase “based on” means both “based only on” and “based at least on”.

[0170] Any reference to an element using the designations "first", "second", etc. used in this disclosure does not necessarily limit the number or order of these elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Therefore, a reference to a first element and a second element does not mean that only two elements can be used or that the first element must precede the second element in any form.

[0171] The “unit” in the configuration of each of the above-mentioned devices may be replaced with a “section”, “circuit”, “device” or the like.

[0172] When the terms "include", "including" and their variations are used in the present disclosure, these terms are intended to be inclusive, just like the term "comprising". Furthermore, the term "or" used in the present disclosure does not mean an exclusive or.

[0173] A radio frame may be composed of one or more frames in the time domain. In the time domain, one or more frames may be referred to as a subframe. A subframe may also be composed of one or more time slots in the time domain. A subframe may be a fixed time length (e.g., 1 ms) that is independent of a numerology.

[0174] A parameter set may be a communication parameter applied to at least one of the transmission and reception of a certain signal or channel. The parameter set may, for example, represent at least one of subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame structure, specific filtering processing performed by the transceiver in the frequency domain, specific windowing processing performed by the transceiver in the time domain, and the like.

[0175] 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.

[0176] A time slot may contain multiple mini-slots. Each mini-slot may be composed of one or more symbols in the time domain. In addition, a mini-slot may also be referred to as a sub-slot. A mini-slot may be composed of fewer symbols than a time slot. A PDSCH (or PUSCH) transmitted in units of time greater than a mini-slot may be referred to as a PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot may be referred to as a PDSCH (or PUSCH) mapping type B.

[0177] A radio frame, a subframe, a time slot, a mini-time slot, and a symbol all represent time units for transmitting signals. A radio frame, a subframe, a time slot, a mini-time slot, and a symbol may be referred to by other corresponding names.

[0178] For example, one subframe may be referred to as a transmission time interval (TTI), multiple consecutive subframes may be referred to as a TTI, and one time slot or one mini time slot may be referred to as a TTI. That is, at least one of a subframe and a TTI may be a subframe (1ms) in existing LTE, a period shorter than 1ms (e.g., 1-13 symbols), or a period longer than 1ms. In addition, the unit representing a TTI may not be referred to as a subframe, but as a time slot, a mini time slot, or the like.

[0179] Here, TTI refers to, for example, the minimum time unit for scheduling in wireless communication. For example, in the LTE system, the base station performs scheduling to allocate wireless resources (frequency bandwidth, transmission power, etc. that can be used in each terminal 20) to each terminal 20 in units of TTI. In addition, the definition of TTI is not limited to this.

[0180] TTI can be a transmission time unit of data packets (transport blocks), code blocks, code words, etc. after channel coding, or a processing unit such as scheduling and link adaptation. In addition, when TTI is given, the time interval (e.g., the number of symbols) to which the transport block, code block, code word, etc. is actually mapped can be shorter than the TTI.

[0181] In addition, when one time slot or one mini time slot is called TTI, one or more TTIs (i.e., one or more time slots or one or more mini time slots) can be the minimum time unit for scheduling. In addition, the number of time slots (mini time slots) constituting the minimum time unit for scheduling can be controlled.

[0182] A TTI having a time length of 1 ms may also be referred to as 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 referred to as a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a mini time slot, a sub time slot, a time slot, etc.

[0183] In addition, for a long TTI (for example, a normal TTI, a subframe, etc.), it can be replaced with a TTI having a time length exceeding 1ms, and for a short TTI (for example, a shortened TTI, etc.), it can be replaced with a TTI having a TTI length smaller than the long TTI (longTTI) and greater than 1ms.

[0184] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain. In the frequency domain, it may include one or more consecutive subcarriers. The number of subcarriers included in an RB may be the same regardless of the parameter set, for example, it may be 12. The number of subcarriers included in an RB may also be determined based on the parameter set.

[0185] In addition, the time domain of an RB may include one or more symbols, and may be the length of one slot, one mini slot, one subframe, or one TTI. One TTI, one subframe, etc. may be composed of one or more resource blocks, respectively.

[0186] In addition, one or more RBs may also be referred to as a physical resource block (PRB: Physical RB), a sub-carrier group (SCG: Sub-Carrier Group), a resource element group (REG: Resource Element Group), a PRB pair, an RB pair, etc.

[0187] In addition, 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.

[0188] A bandwidth part (BWP) (also referred to as partial bandwidth, etc.) may also represent a subset of contiguous common RBs (common resource blocks) for a parameter set in a carrier. Here, the common RBs may be identified by the index of the RBs relative to the common reference point of the carrier. PRBs may be defined in a BWP and numbered within the BWP.

[0189] 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 the terminal 20 within one carrier.

[0190] At least one of the set BWPs may be active, and it is not assumed that the terminal 20 transmits and receives a predetermined signal / channel outside the activated BWP. In addition, "cell", "carrier" and the like in the present disclosure may be replaced with "BWP".

[0191] The above structures of radio frames, subframes, time slots, mini-time slots, and symbols are merely examples. For example, the number of subframes included in a radio frame, the number of time slots per subframe or radio frame, the number of mini-time slots included in a time slot, the number of symbols and RBs included in a time slot or mini-time slot, the number of subcarriers included in an RB, the number of symbols in a TTI, the symbol length, and the cyclic prefix (CP) length may be changed in various ways.

[0192] In the present disclosure, when an article is added by translation, such as a, an, and the in English, the present disclosure also includes a case where the noun following the article is in a plural form.

[0193] In the present disclosure, the term "A and B are different" may mean "A and B are different from each other". In addition, the term may mean "A and B are different from C, respectively". The terms "separate" and "combined" may also be interpreted in the same way as "different".

[0194] Each form / implementation described in the present disclosure may be used alone or in combination, and may be switched depending on the execution. In addition, notification of predetermined information (e.g., notification of "yes X") is not limited to being performed explicitly, but may also be performed implicitly (e.g., not notifying the predetermined information).

[0195] The present disclosure is described in detail above, but it should be clear to those skilled in the art that the present disclosure is not limited to the embodiments described in the present disclosure. The present disclosure can be implemented as a modification and variation without departing from the subject matter and scope of the present disclosure as determined by the claims. Therefore, the purpose of the description of the present disclosure is to illustrate and not to have any limiting meaning on the present disclosure.
