Description

Technical Field

[0001] The present invention relates to a terminal and a power supply method in a wireless communication system. Background Art

[0002] In NR (New Radio) (also called "5G"), which is the successor system to LTE (Long Term Evolution), technologies that meet the requirements of large-capacity systems, high data transmission speeds, low latency, simultaneous connection of multiple terminals, low costs, and power saving are being studied (for example, non-patent document 1).

[0003] In LTE and NR, UE types or capabilities are defined for the IoT (Internet of Things) by reducing the mandatory functions typically supported by terminals, such as those related to transmit and receive bandwidth and the number of antennas. For example, LTE defines eMTC (enhanced Machine Type Communication) and NB-IoT (Narrow Band IoT), while NR defines RedCap (Reduced Capability).

[0004] In recent years, there has been growing interest in wireless power supply technologies for various devices, including IoT terminals, and research is actively underway. For example, research is underway to allocate specific frequency bands to wireless power supply, verify its impact on the human body and radio interference with other communication devices, and, if no issues are identified, expand its use outdoors and in human spaces.

[0005] 3GPP (registered trademark) is conducting standardization research on ultra-low power terminals based on the premise of power supply from the surrounding environment, such as sunlight, wind, water, electromagnetism, heat, sound, vibration, or wirelessly (for example, Non-Patent Document 2).

[0027] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. Note that the embodiment described below is merely an example, and the embodiment to which the present invention is applied is not limited to the following embodiment.

[0028] In the operation of the wireless communication system according to the embodiments of the present invention, existing technologies are appropriately used. Examples of such existing technologies include, but are not limited to, existing LTE. Furthermore, unless otherwise specified, the term "LTE" used in this specification has a broad meaning encompassing LTE-Advanced and subsequent generations (e.g., NR and 6G wireless specifications).

[0029] In addition, in the embodiments of the present invention described below, terms such as SS (Synchronization Signal), PSS (Primary SS), SSS (Secondary SS), PBCH (Physical broadcast channel), PRACH (Physical random access channel), PDCCH (Physical Downlink Control Channel), PDSCH (Physical Downlink Shared Channel), PUCCH (Physical Uplink Control Channel), and PUSCH (Physical Uplink Shared Channel) used in existing LTE are used. These are for convenience of description, and the same signals, functions, etc. may also be referred to by other names. In addition, the above terms in NR correspond to NR-SS, NR-PSS, NR-SSS, NR-PBCH, NR-PRACH, etc. However, even signals used for NR are not necessarily explicitly recorded as "NR-".

[0030] Furthermore, in the embodiment of the present invention, the duplexing method may be a TDD (Time Division Duplex) method, an FDD (Frequency Division Duplex) method, or another method (eg, Flexible Duplex, etc.).

[0031] Furthermore, in the embodiment of the present invention, “configuring” wireless parameters and the like may be pre-configuring predetermined values, or may be configuring wireless parameters notified from the base station 10 or the terminal 20 .

[0032] Figure 1 1 is a diagram showing a configuration example (1) of a wireless communication system in an embodiment of the present invention. 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 only an example, and there may be multiple base stations and terminals.

[0033] 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 by 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 the number of resource blocks. The base station 10 sends synchronization signals and system information to the terminal 20. Synchronization signals are, for example, NR-PSS and NR-SSS. System information is sent, for example, through NR-PBCH, also called broadcast information. The synchronization signal and system information may also be referred to as SSB (SS / PBCH block). As shown in FIG. 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 transmit 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.

[0034] 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, terminal 20 receives control signals or data from base station 10 via DL and transmits control signals or data to base station 10 via UL, thereby utilizing various communication services provided by the wireless communication system. Furthermore, terminal 20 receives various reference signals transmitted from base station 10 and measures propagation path quality based on the reception results of these reference signals.

[0035] Terminal 20 can perform carrier aggregation, which bundles multiple cells (multiple CCs) to communicate with base station 10. Carrier aggregation uses one PCell (Primary Cell) and one or more SCells (Secondary Cells). Alternatively, a PUCCH-SCell with a PUCCH can be used.

[0036] With the widespread adoption of a wide range of devices, such as IoT terminals, research is underway to find ways to charge or replace batteries in these vast numbers of devices. In recent years, wireless power transfer (WPT) technology has seen increasing interest and active research into methods for powering various devices, including IoT terminals.

[0037] Wireless power supply is being researched in IoT devices due to cost and battery replacement considerations, while in handheld devices, it is also being researched due to cost and the size and shape of the device. If high-efficiency, high-capacity wireless power supply can be achieved, it can be expected to lead to further sophistication and diversification of devices.

[0038] For example, research is underway to allocate specific frequency bands for wireless power transmission, verify its impact on the human body and radio wave interference with other communication equipment, and if no problems arise, expand its use outdoors and in spaces with people.

[0039] Furthermore, 3GPP (registered trademark) is conducting standardization research on ultra-low-power terminals that rely on environmental power supply, such as sunlight, wind, water, electromagnetic fields, heat, sound, vibration, or wireless power supply. Wireless power supply eliminates the need for battery charging, wired charging, or battery replacement.

[0040] The terminal 20 may also be powered wirelessly from the base station 10 or a power transmission device 30 connected to the base station 10. The base station 10 etc. that transmits power to the terminal 20 may be the same as or different from the base station 10 etc. that transmits and receives data.

[0041] The power transmitting device 30 , which is a device that supplies power, may also have the following features 1) to 3).

[0042] 1) The power transmission device 30 may be a base station, an IAB (Integrated Access Backhaul), a repeater, a RIS (Reconfigurable Intelligent Surface), a TRP (Transmission / Reception Point), or a terminal. The function of the power transmission device may also be specified separately.

[0043] 2) It is conceivable that the base station, IAB, repeater, RIS, TRP or terminal that performs wireless power supply has full duplex function.

[0044] 3) The IAB, repeater, RIS, TRP or terminal that performs wireless power supply can be in a state of being connected to the base station during power supply, or can be in a state of being disconnected during power supply.

[0045] In addition, power transmission equipment, base stations, IABs, repeaters, RISs, TRPs, and terminals can also be interchanged.

[0046] The terminal 20 to be powered may have the following features 1) to 3).

[0047] 1) It can be moved or fixed in position.

[0048] 2) It may or may not have the ability to connect to a base station, IAB, repeater, RIS, TRP or terminal for data communication.

[0049] 3) Regarding the type or shape of the terminal, it can be a handheld terminal (smartphone, tablet computer, etc.), IoT terminal (sensor, wearable terminal, surveillance camera, smart device, home appliance, etc.), ambient power (Ambient) IoT terminal (tag, card, etc.), robot, drone, electric car, PC, etc., but not limited to these.

[0050] Figure 2 1 is a diagram showing a configuration example (1) of wireless power supply according to an embodiment of the present invention. Figure 2 As shown, the power transmission device 30 may be installed separately from the base station 10 and wirelessly power the terminal 20. The base station 10 may also communicate with the terminal 20 to control the wireless power supply provided by the power transmission device 30. The power transmission device 30 may be installed indoors on a wall or ceiling, or outdoors on a utility pole or other facility. Furthermore, the terminal 20 may operate as the power transmission device 30 and wirelessly power another terminal 20. Hereinafter, wireless power supply from a power transmission device 30 not included in the base station 10 to a terminal 20 will also be referred to as wireless power supply from the base station 10 to the terminal 20.

[0051] Figure 3 : is a diagram showing a configuration example (2) of wireless power supply according to an embodiment of the present invention. Figure 3 As shown, the power supply device 30 may be provided together with the base station 10 to perform wireless power supply to the terminal 20. The base station 10 may also communicate with the terminal 20 to control the wireless power supply by the power transmission device 30. Hereinafter, the wireless power supply from the power transmission device 30 included in the base station 10 to the terminal 20 will also be described as the wireless power supply from the base station 10 to the terminal 20.

[0052] To compensate for reduced transmission efficiency, wireless power delivery is assumed to use higher transmission power than conventional wireless communication systems. Therefore, depending on the wireless power delivery method and frequency, interference with coexisting wireless communication systems is possible. However, the details of the process for controlling wireless power delivery scheduling are unknown.

[0053] Therefore, a terminal 20 receiving power wirelessly from the power transmitting device 30 can also receive a notification regarding the resources used for power supply from the base station 10 and receive power based on this notification. Furthermore, a terminal 20 to which power is to be transmitted can also receive a notification regarding the resources used for power supply from the base station 10 and transmit power based on this notification.

[0054] Figure 4 This is a sequence diagram for explaining an example of wireless power supply according to an embodiment of the present invention. In step S101, the base station 10 transmits a notification regarding power supply resources to the terminal 20. In the following step S102, the terminal 20 receives wireless power supply from the power transmitting device 30 based on the notification.

[0055] The terminal 20 may also perform operations related to resources for power supply, such as operations 1) to 4) shown below.

[0056] Action 1) The terminal 20 may be notified by the base station 10 that the base station 10 or the power transmitting device 30 supplies power using a specific time resource.

[0057] The specific time resource may be notified as a periodic resource or an aperiodic resource, or may be notified of being enabled or disabled (released) as a semi-persistent resource.

[0058] This specific time resource may also be notified as a specific time width.

[0059] The notification unit of the specific time resource may be a time slot, a frame, a millisecond, a second, or a minute.

[0060] Together with the specific time resource, the receiving beam related to power supply of the base station 10 or the power transmitting device 30 corresponding to the specific time resource may be notified. Hereinafter, the receiving beam related to power supply or the transmitting beam related to power supply is also referred to as a power supply beam.

[0061] Terminal 20 may also receive power during the notified time resources and / or time resources in which it is capable of receiving power. For example, terminal 20 may receive power during a time resource using a power beam from base station 10 or power transmitting device 30 that corresponds to the power beam used by the terminal. Terminal 20 may receive power during all or part of these time resources.

[0062] Figure 5 This is a diagram for explaining an example (1) of wireless power supply according to an embodiment of the present invention. Figure 5 As shown, terminal 20A can also receive power through the time resource of resource 1 and the power beam associated with resource 1. Terminal 20B can also receive power through the time resource of resource 2 and the power beam associated with resource 2. Information representing resource 1 can be notified to terminal 20A, and information representing resource 2 can also be notified to terminal 20B.

[0063] The terminal 20 may also assume that the time between the notification regarding power supply and the power supply start timing is longer than a predetermined time. For example, the predetermined time may be the processing time of the terminal 20.

[0064] Through the above-mentioned operation 1), the terminal 20 can receive power supply at an appropriate time resource.

[0065] Action 2) The terminal 20 may be notified by the base station 10 to supply power using a specific frequency resource.

[0066] The specific frequency resource may be notified as a continuous resource or as a non-contiguous resource.

[0067] This specific frequency resource may also be notified as a specific frequency width.

[0068] The notification unit of the specific frequency resource may be a specific frequency width, a frequency band, a frequency band, a subcarrier, a resource block, or a BWP.

[0069] Along with the specific frequency resource, the receiving beam related to power supply of the base station 10 or the power transmitting device 30 corresponding to the specific frequency resource may be notified. Hereinafter, the receiving beam related to power supply or the transmitting beam related to power supply is also referred to as a power supply beam.

[0070] Terminal 20 may also receive power in the notified frequency resources and / or frequency resources in which the terminal can receive power. For example, terminal 20 may receive power using a frequency resource using a power beam from base station 10 or power transmitting device 30 that corresponds to the power beam used by the terminal. Terminal 20 may receive power in all or a portion of the above frequency resources.

[0071] Action 3) Notification regarding the power supply resource may be performed in any of the following formats.

[0072] 3a) The format can be any one of SIB (which can be a SIB for wireless power supply), MCCH (Multicast control channel) or MTCH (Multicast traffic channel), or group common DCI. It is also possible to broadcast multiple or all information about which power supply beam is used to perform power supply in which power supply resource. It is also possible to broadcast resource information related to the power supply beam corresponding to the communication beam used in the broadcast. A new DCI format can be defined, and the PDCCH resources (CORESET, search space, etc.) for receiving the new DCI format can be set.

[0073] Figure 6 This is a diagram for explaining example (2) of wireless power supply according to an embodiment of the present invention. Figure 6 As shown, terminals 20A, 20B, and 20C belonging to group 1 can also receive power through the time resources of resource 1 and the power beam associated with resource 1. Terminals 20D and 20E belonging to group 2 can also receive power through the time resources of resource 2 and the power beam associated with resource 2. Information representing resource 1 can be broadcast to group 1 and / or group 2, and information representing resource 2 can also be broadcast to group 1 and / or group 2.

[0074] 3b) The format can be UE-specific RRC settings, MAC-CE, or unicast DCI. Information about the resources that the terminal 20 should receive power can also be notified through this format. Resource information related to the power beam corresponding to the communication beam used in the notification based on this format can also be notified. A new DCI format can be defined, and PDCCH resources (CORESET, search space, etc.) for receiving the new DCI format can also be set. Notification related to power resources can also be performed via fields in the DCI format for communication (for example, DCI for scheduling PDSCH).

[0075] 3c) A RNTI (Radio Network Temporary Identifier) ​​for transmitting power supply related information may be defined and used. This RNTI may be used for transmission and reception in 3a) and 3b) above.

[0076] 3d) The format of notification can be determined by RRC parameters.

[0077] 3e) UE capabilities indicating which formats of notifications are supported may be defined, and the terminal 20 may use the UE capabilities to report supported functions to the base station 10. Furthermore, supporting wireless power delivery may also mean supporting multiple or all of the defined notification formats.

[0078] Through the above-mentioned operation 3), notification regarding the power supply resource can be performed in an appropriate format.

[0079] Action 4) The base station 10 may transmit to the terminal 20 an instruction regarding power transmission to another terminal 20 .

[0080] Power supply from the terminal 20 to the other terminal 20 may also be performed through D2D communication. The above-mentioned actions 1), 2), and 3) may also be applied to the instruction.

[0081] According to the above-described embodiment, the terminal 20 can efficiently receive wireless power supply based on the scheduling indicating the resources for performing wireless power supply.

[0082] That is, in the wireless communication system, it is possible to control the scheduling of wireless power supply execution.

[0096] The block diagram used in the description of the above embodiment ( Figure 7 and Figure 8) 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 it 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).

[0130] The above describes the embodiments of the present invention, but the disclosed invention is not limited to such embodiments, and those skilled in the art should understand various variations, modifications, substitutions, replacements, etc. In order to facilitate understanding of the invention, specific numerical examples are used for description, but unless otherwise specified, these numerical values ​​are only examples, and any appropriate values ​​may also be used. The distinction between items in the above description is not essential to the present invention. You can combine and use the matters recorded in two or more items as needed, and you can also apply the matters recorded in a certain item to the matters recorded in another item (as long as there is no contradiction). 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 steps described in the embodiment, the order of processing can be swapped if there is no contradiction. For the convenience of explaining the processing, the base station 10 and the terminal 20 are described using a functional block diagram, but such a device can also be implemented by hardware, software, or a combination thereof.

[0131] 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 can be implemented through physical layer signaling (for example, DCI (Downlink Control Information), UCI (Uplink Control Information)), high-layer signaling (for example, RRC (Radio Resource Control) signaling, MAC (Medium Access Control) signaling, broadcast information (MIB (Master Information Block), SIB (System Information Block)), 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.

[0132] Each form / embodiment described in the present disclosure can also be applied to LTE (Long Term Evolution), LTE-A (LTE-Advanced), SUPER 3G, IMT-Advanced, 4G (4th generation mobile communication system), 5G (5th generation mobile communication system), 6G (6th generation mobile communication system), xG (xth generation mobile communication system) (xG (x is, for example, an integer or a decimal)), FRA (Future Radio Access), NR (New Radio), New Radio Access (NX), Future Generation Radio Access (FX), W-CDMA (registered trademark), GSM (registered trademark), CDMA2000, UMB (Ultra Mobile Broadband), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE At least one of 802.20, UWB (Ultra-WideBand), Bluetooth (registered trademark), other appropriate systems, and next-generation systems that are expanded, modified, created, or specified based on these systems. Furthermore, a combination of multiple systems (e.g., a combination of at least one of LTE and LTE-A with 5G) may also be employed.

[0133] The processing steps, sequences, and flows of each form / implementation described in this specification may be rearranged in order 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.

[0134] In this specification, specific actions performed by base station 10 may also be performed by its upper node, depending on the situation. In a network consisting of one or more network nodes including base station 10, it is obvious that various actions performed for communication with terminal 20 can be performed by at least one of base station 10 and other network nodes other than base station 10 (e.g., MME or S-GW, but not limited to these). While the above example illustrates a single other network node other than base station 10, the other network node may also be a combination of multiple other network nodes (e.g., MME and S-GW).

[0135] The information or signals described in this disclosure can be output from a higher layer (or lower layer) to a lower layer (or higher layer), and can also be input or output via multiple network nodes.

[0136] Input or output information can be stored in a specific location (e.g., memory) or managed using a management table. Input or output information can be rewritten, updated, or appended. Output information can also be deleted. Input information can also be sent to other devices.

[0137] The determination in the present disclosure can be made by a value represented by 1 bit (0 or 1), a Boolean value (Boolean: true or false), or by comparison of numerical values ​​(for example, comparison with a predetermined value).

[0138] 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.

[0139] Additionally, software, commands, information, and the like may be transmitted and received via a transmission medium. For example, if software is transmitted from a web page, server, or other remote source using at least one of a wired technology (coaxial cable, fiber optic cable, twisted pair, 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.

[0140] 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.

[0141] In addition, the terms used in this disclosure and those necessary 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, or a frequency carrier.

[0142] As used in this disclosure, the terms "system" and "network" are used interchangeably.

[0143] 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.

[0144] 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 suitable names, and therefore the names assigned to these channels and information elements are non-limiting in any respect.

[0145] In this disclosure, terms such as "base station (BS)," "wireless base station," "base station apparatus," "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.

[0146] A base station can accommodate one or more (for example, three) cells. 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 (RRH) for indoor use). Terms such as "cell" or "sector" refer to a portion or the entire coverage area of ​​at least one of the base station and base station subsystem that provide communication services within that coverage area.

[0147] 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.

[0148] In the present disclosure, terms such as “mobile station (MS)”, “user terminal (user terminal)”, “user equipment (UE)”, and “terminal” can be used interchangeably.

[0149] 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.

[0150] 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 refers to an object that can move, and the moving speed is arbitrary. In addition, of course, the situation where the mobile body stops is also included. The mobile body includes, for example, vehicles, transport vehicles, cars, motorcycles, bicycles, connected cars, shovel cars, bulldozers, wheel loaders, dump trucks, forklifts, trains, buses, rear cars, rickshaws, ships and other watercraft, airplanes, rockets, artificial satellites, drones (registered trademark), multicopters, quadcopters, balloons, and objects mounted thereon, and is not limited thereto. In addition, the mobile body may also be a mobile body that drives autonomously based on an operating instruction. It can be a vehicle (such as a car or airplane), a mobile object that moves unmanned (such as a drone or self-driving car), or a robot (manned or unmanned). Furthermore, at least one of the base station and the mobile station also includes a device that does not necessarily move during communication. For example, at least one of the base station and the mobile station can be an IoT (Internet of Things) device such as a sensor.

[0151] In addition, the base station in the present disclosure can also be replaced by a user terminal. For example, the various forms / implementations of the present disclosure can also be applied to a structure in which the communication between the base station and the user terminal is replaced by the communication between multiple terminals 20 (for example, it can also be called D2D (Device-to-Device: device to device), V2X (Vehicle-to-Everything: vehicle-to-everything) etc.). In this case, it can also be set as a structure in which the terminal 20 has the functions of the above-mentioned base station 10. 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 also be replaced by side channels.

[0152] 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.

[0153] As used in this disclosure, terms such as "determining" and "determining" sometimes encompass a variety of actions. For example, "determining" and "judging" may include considering matters such as judging, calculating, computing, processing, deriving, investigating, looking up, searching, or inquiring (e.g., searching in a table, database, or other data structure), or ascertaining as matters that have been "judged" or "determined." Furthermore, "determining" and "receiving" (e.g., receiving information), transmitting (e.g., sending information), inputting, outputting, or accessing (e.g., accessing data in a memory) as matters that have been "judged" or "determined." Furthermore, "determining" and "resolving" may include matters such as selecting, choosing, establishing, or comparing. That is, "judgment" and "decision" can include matters 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.

[0154] 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.

[0155] The reference signal may be referred to as RS (Reference Signal) for short, or may be called a pilot signal depending on the applied standard.

[0156] 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.”

[0157] Any reference to an element using the designations "first," "second," etc., as 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 way to distinguish between two or more elements. Therefore, a reference to a first element and a second element does not imply that only two elements can be used or that the first element must precede the second element in any manner.

[0158] The “unit” in the configuration of each of the above-mentioned devices may be replaced with a “section,” “circuit,” “device,” or the like.

[0159] 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.

[0160] 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 also be a fixed time length (e.g., 1 ms) that is independent of the numerology.

[0161] 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.

[0162] 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.

[0163] 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 time units larger than a mini-slot may be referred to as PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot may be referred to as PDSCH (or PUSCH) mapping type B.

[0164] 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.

[0165] 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 (for example, 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.

[0166] 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 wireless resources (such as the frequency bandwidth and transmit power available to each terminal 20) to each terminal 20 using TTIs as units. The definition of TTI is not limited to this.

[0167] 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.

[0168] In addition, when one time slot or one 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 also be 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.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] 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 each be composed of one or more resource blocks.

[0173] 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.

[0174] 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.

[0175] A bandwidth part (BWP) (also referred to as a fractional bandwidth) can also represent a subset of contiguous common resource blocks (RBs) used for a particular parameter set within a particular 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.

[0176] 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.

[0177] At least one of the configured BWPs may be active, and it may not be 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".

[0178] The above-described structures of radio frames, subframes, slots, mini-slots, and symbols are merely examples.
