Description

Technical Field

[0001] This invention relates to terminals and communication methods in wireless communication systems. Background Technology

[0002] Within the 3GPP (3rd Generation Partnership Project), research was conducted on a wireless communication method known as 5G or NR (New Radio) to further increase system capacity, improve data transmission speed, and reduce latency in the radio space. In 5G, various wireless technologies and network architectures were researched to meet the requirements of achieving throughput of over 10Gbps and radio latency of less than 1ms (e.g., Non-Patent Literature 1 and Non-Patent Literature 2).

[0003] Furthermore, various requirements for next-generation 6G were further investigated. These requirements include ultra-broadband communication, mission-critical communication, ultra-massive connection, universal coverage, intelligent connection, and ubiquitous sensing.

[0004] To achieve this requirement, a new concept is proposed with the goals of being scalable (e.g., more efficient to use in the future), customizable (e.g., easier to apply), and sustainable (e.g., cost reduction and a more robust structure).

[0026] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, the embodiments described below are merely examples, and the application of the present invention is not limited to the embodiments described below.

[0027] In the operation of the wireless communication system according to embodiments of the present invention, existing technologies are appropriately used. These existing technologies include, for example, existing LTE, but are not limited to, existing LTE. Furthermore, unless otherwise stated, the term "LTE" as used in this specification has a broad meaning that includes LTE-Advanced and subsequent methods (e.g., NR).

[0028] Furthermore, in the embodiments of the present invention described below, the terms 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 systems are used. These are for ease of description, and the same signals and functions may also be referred to by other names. Additionally, the above terms in NR correspond to NR-SS, NR-PSS, NR-SSS, NR-PBCH, NR-PRACH, etc. However, even signals used in NR are not necessarily explicitly written as "NR-".

[0029] In addition, in embodiments of the present invention, the duplex mode can be TDD (Time Division Duplex), FDD (Frequency Division Duplex), or other modes (e.g., Flexible Duplex).

[0030] Furthermore, in embodiments of the present invention, the "configure" wireless parameters can be pre-configured predetermined values, or wireless parameters notified from the base station 10 or the terminal 20.

[0031] Figure 1 This is a diagram illustrating an example structure of a wireless communication system according to an embodiment of the present invention. For example... Figure 1 As shown, the wireless communication system in this embodiment of the invention includes a base station 10 and a terminal 20. Figure 1 The image shows one base station 10 and one terminal 20, but this is just an example; there could be multiple terminals.

[0032] Base station 10 is a communication device that provides one or more cells and wirelessly communicates with terminal 20. The physical resources of the wireless signal are defined in the time and frequency domains. 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. Base station 10 sends synchronization signals and system information to terminal 20. Synchronization signals are, for example, NR-PSS and NR-SSS. System information is transmitted, for example, via NR-PBCH, also known as broadcast information. Synchronization signals and system information can also be referred to as SSB (SS / PBCH block). Figure 1 As shown, base station 10 sends control signals or data to terminal 20 via DL (Downlink) and receives control signals or data from terminal 20 via UL (Uplink). Both base station 10 and terminal 20 are capable of beamforming for signal transmission and reception. Furthermore, both base station 10 and terminal 20 can apply MIMO (Multiple Input Multiple Output) based communication to DL or UL. Additionally, base station 10 and terminal 20 can also communicate via CA (Carrier Aggregation) based secondary cells (SCell) and primary cells (PCell). Moreover, terminal 20 can also communicate via DC (Dual Connectivity) based primary cells of base station 10 and primary SCG cells of other base stations 10.

[0033] Terminal 20 is a communication device with wireless communication capabilities, such as a smartphone, mobile phone, tablet computer, wearable terminal, or 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. Additionally, terminal 20 receives various reference signals transmitted from base station 10 and performs propagation path quality measurements based on the reception results of these reference signals.

[0034] In this context, 32 HARQ (Hybrid Automatic Repeat Request) processes were introduced for DL ​​or UL, and corresponding UE capability reports were defined. This UE capability is contingent upon supporting FR2-2.

[0035] For example, this capability is reported to the network via the information elements support32-DL-HARQ-ProcessPerSCS-r17 and maxCC-32-DL-HARQ-ProcessFR2-2-r17 (refer to Non-Patent Document 4). This capability indicates that, with SCS values ​​of 120kHz, 480kHz, or 960kHz, the UE supports a maximum of 32 HARQ processes for DL. Furthermore, regarding maxCC-32-DL-HARQ-ProcessFR2-2-r17, the candidate values ​​for the maximum number of supported CCs can also be {1, 2, 3, 4, 6, 8, 16, 32}.

[0036] Furthermore, for example, this capability is reported to the network via the information elements support32-UL-HARQ-ProcessPerSCS-r17 and maxCC-32-UL-HARQ-ProcessFR2-2-r17 (refer to Non-Patent Document 4). This capability indicates that, with SCS values ​​of 120kHz, 480kHz, or 960kHz, the UE supports a maximum of 32 UL-oriented HARQ processes. Additionally, regarding maxCC-32-UL-HARQ-ProcessFR2-2-r17, the candidate values ​​for the maximum number of supported CCs can be {1, 2, 3, 4, 5, 8, 16, 32}.

[0037] Furthermore, in previous NR-NTN (Non-Terrestrial Network) systems, 32 HARQ processes were introduced, defining corresponding UE capability reports. These UE capabilities are only available for NTN systems using satellites, HAPS (High Altitude Platform Stations), or similar base stations.

[0038] For example, this capability is reported to the network via the information element max-HARQ-ProcessNumber-r17 (refer to Non-Patent Document 4). Regarding the combination of the number of HARQ processes for UL and the number of HARQ processes for DL, it indicates that the UE supports {16,32}, {32,16}, or {32,32}.

[0039] Figure 2 This is a diagram illustrating the number of HARQ processes in embodiments of the present invention. For example, in a TN (Terrestrial Network), 16 HARQ processes are supported. However, for example, when CA is performed using a primary cell with a 30kHz SCS and TDD mode of "DDDSUUDDDD" in FR1 and a secondary cell with a 120kHz SCS and TDD mode of "DDDSU" in FR2, and the secondary cell PUCCH is not applied, as... Figure 2 As shown, the number of HARQ processes needs to be, for example, 25. Furthermore, Figure 2 This is just one example; other TDD modes and FDD scenarios within TN can also be considered.

[0040] Therefore, in the TN and / or frequency bands lower than FR2-2, more than 16 HARQ processes can also be supported. Furthermore, the UE can report support for more than 16 HARQ processes to the network as a UE capability.

[0041] The UE can also report its ability to support 32 HARQ processes in the TN and / or in bands lower than FR2-2 using the following methods. Furthermore, the number of HARQ processes is not limited to 32 and can be any value exceeding 16.

[0042] Figure 3 This is a timing diagram illustrating an example of executing a capability report in an embodiment of the present invention. In step S11, base station 10 sends a UE Capability Enquiry as RRC signaling to terminal 20. In step S12, terminal 20 sends a UE Capability Information report as RRC signaling to base station 10. In step S13, base station 10 may configure 32 HARQ processes for terminal 20. For example, base station 10 may perform scheduling for terminal 20 that requires 32 HARQ processes.

[0043] For example, the UE can report the capability to the network via more than one capability signaling, such as two capability signaling, as shown in some or all of a)-d) below. That is, at least two of a)-d) below can be reported to the network.

[0044] a) Does it support 32 HARQ processes? For example, this capability can be reported per UE, per frequency band, per frequency band combination, per feature set, per feature set of each CC, or per FR.

[0045] b) The maximum number of CCs that can be utilized across 32 HARQ processes. For example, {1,2,3,4,6,8,16,32} could be candidate values. This capability can be the capability per reporting unit as described in a) above. For example, this capability can be reported per UE, per frequency band, per frequency band combination, per feature set, per feature set of each CC, or per FR.

[0046] c) Capable of utilizing carrier types from 32 HARQ processes. For example, {FR1 licensed TDD, FR1 unlicensed TDD, FR2} can also be candidate values. This capability can be reported, for example, per UE, per frequency band, per frequency band combination, per feature set, per feature set of each CC, or per FR.

[0047] d) The ability to utilize an SCS or a combination of SCSs with 32 HARQ processes. For example, it is also possible to utilize 32 HARQ processes in a 120kHz SCS. This capability can be reported, for example, per UE, per frequency band, per frequency band combination, per feature set, per feature set of each CC, or per FR.

[0048] Alternatively, capabilities can be reported separately in DL and UL. Furthermore, reporting a specific capability can be contingent upon the requirement that other capabilities must be supported. For example, a) above can also be a prerequisite for b) above.

[0049] For example, the UE can also report the capability to the network via a capability signaling. For example, the signaling for TN, FR1, and / or FR2 can also be defined using the same structure as the signaling indicating whether 32 HARQ processes for NTN are supported. For example, the capability can also be a candidate value of {16,32}, {32,16}, or {32,32} for the combination of the number of HARQ processes for UL and the number of HARQ processes for DL.

[0050] For example, the UE can also report this capability to the network via two capability signaling messages. For example, the signaling for TN, FR1, and / or FR2 can be defined using the same structure as the signaling indicating whether 32 HARQ processes for FR2-2 are supported. For example, the capability can also be reported to the network via information elements indicating whether 32 HARQ processes are supported and information elements indicating the maximum number of CCs. Additionally, the candidate values ​​for the maximum number of supported CCs can be {1, 2, 3, 4, 6, 8, 16, 32}. Information elements indicating whether 32 HARQ processes are supported can also be reported per frequency band. Information elements indicating the maximum number of CCs can also be reported per combination of frequency bands.

[0051] As described above, for UEs that report the ability to support 32 HARQ processes in the TN and / or in frequency bands lower than FR2-2, 32 HARQ processes for DL ​​and / or UL can also be configured in that frequency band, that combination of frequency bands, or that CC. For example, the RRC parameter harq-ProcessNumberSizeDCI-1-1 can be configured for the UE. Furthermore, the parameter name is an example; information elements representing the activation of 32 HARQ processes can also be defined.

[0052] Figure 4 This is a flowchart illustrating an example of DCI reception in an embodiment of the present invention. In step S21, the UE determines whether the upper-layer parameter harq-ProcessNumberSizeDCI-1-1 is set. If it is set (S21 is "Yes"), proceed to step S22; if it is not set (S21 is "No"), proceed to step S24.

[0053] In step S22, the UE receives the DCI. This DCI can be in DCI format 1_1. In step S23, the UE can assume that the HARQ process number field included in the DCI is 5 bits.

[0054] On the other hand, in step S24, the UE receives the DCI. This DCI can be in DCI format 1_1. In step S25, the UE can assume that the HARQ process number field included in the DCI has 4 bits.

[0055] As a condition for setting the above RRC parameter harq-ProcessNumberSizeDCI-1-1, the above-mentioned capability related to supporting 32 HARQ processes in TN and / or in frequency bands lower than FR2-2 can be specified.

[0056] Additionally, UE can also represent parameters for signaling notification per UE. Frequency band can also represent signaling notification per frequency band. BC can also represent signaling notification per combination of frequency bands. FS can represent signaling notification per feature set, or signaling notification per feature set of each frequency band in each combination of frequency bands. FSPC can represent signaling notification per feature set of each CC, or signaling notification per feature set of each CC in each frequency band in each combination of frequency bands.

[0057] According to the above embodiments, terminal 20 can send information to the network through UE capability report indicating whether it supports 32 HARQ processes in TN and / or frequency ranges lower than FR2-2, and the network can set 32 ​​HARQ processes for terminal 20.

[0058] That is, in a wireless communication system, it is possible to perform communication with an appropriate number of HARQ (Hybrid Automatic Repeat Request) processes applied.

The distinctions between items in the above description are not essential to the present invention. Items described in two or more items may be combined as needed, and items described in one item may be applied to items described in another item (as long as there is no contradiction). The boundaries of functional units or processing units in the functional block diagram do not necessarily correspond to the boundaries of physical components. Multiple functional units may be operated by a single physical component, or a single functional unit may be operated by multiple physical components. Regarding the processing described in the embodiments, the order of processing may be interchanged unless there is a contradiction. For ease of explanation, a functional block diagram is used to illustrate the base station 10 and terminal 20, but such a device may also be implemented by hardware, software, or a combination thereof.

[0106] Furthermore, the notification of information is not limited to the forms / implementations described in this disclosure, and other methods may also be used. For example, information notification may be implemented through physical layer signaling (e.g., DCI (Downlink Control Information), UCI (Uplink Control Information)), higher layer signaling (e.g., RRC (Radio Resource Control) signaling, MAC (Medium Access Control) signaling), broadcast information (MIB (Master Information Block), SIB (System Information Block)), other signals, or combinations thereof. Additionally, RRC signaling may be referred to as an RRC message, for example, an RRC connection setup message, an RRC connection reconfiguration message, etc.

[0107] The various forms / implementations described in this disclosure can also be applied to systems utilizing LTE (Long Term Evolution), LTE-A (LTE-Advanced), SUPER 3G, IMT-Advanced, 4G (4th generation mobile communication system), 5G (5th generation mobile communication system), FRA (Future Radio Access), NR (new Radio), 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 802.20, UWB (Ultra-Wideband), Bluetooth (registered trademark), other suitable systems, and next-generation systems based on and extended from these systems. Additionally, multiple systems can be combined (e.g., a combination of at least one of LTE and LTE-A with 5G, etc.) for application.

[0108] The processing procedures, timing, and flow of the various forms / implementations described in this specification may be rearranged in order, provided there is no contradiction. For example, the elements of various steps are indicated using an illustrative order for the methods described in this disclosure, but are not limited to the specific order indicated.

[0109] In this specification, certain actions performed by base station 10 may sometimes also be performed by its upper node, depending on the circumstances. In a network consisting of one or more network nodes having base station 10, it is obvious that various actions performed to communicate with terminal 20 can be performed by at least one of base station 10 and other network nodes besides base station 10 (e.g., considering MME or S-GW, but not limited to these). The above example illustrates the case where there is one other network node besides base station 10, but other network nodes can also be a combination of multiple other network nodes (e.g., MME and S-GW).

[0110] The information or signals described in this disclosure can be output from a higher (or lower) layer to a lower (or higher) layer. They can also be input or output via multiple network nodes.

[0111] 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 overwritten, updated, or appended. Output information can also be deleted. Input information can also be sent to other devices.

[0112] The determination in this disclosure can be made by a value represented by 1 bit (0 or 1), by a Boolean value (Boolean: true or false), or by a comparison of numerical values ​​(e.g., a comparison with a predetermined value).

[0113] Software, whether called software, firmware, middleware, microcode, hardware description language, or by other names, should be broadly interpreted as referring to commands, command sets, code, code segments, program code, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions, etc.

[0114] In addition, software, commands, information, etc., can be sent and received via a transmission medium. For example, when using at least one of wired technologies (coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL) etc.) and wireless technologies (infrared, microwave, etc.) to send software from a webpage, server, or other remote source, at least one of these wired and wireless technologies is included within the definition of a transmission medium.

[0115] The information, signals, etc., described in this disclosure can also be represented using any of a variety of different technologies. For example, the data, commands, instructions, information, signals, bits, symbols, chips, etc., that may be involved in the above description can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or photons, or any combination of these.

[0116] Furthermore, the terms used in this disclosure and those necessary for understanding this disclosure may be replaced with terms that have the same or similar meanings. For example, at least one of the channel and symbol may also be a signal (signaling). Additionally, a signal may also be a message. Furthermore, a component carrier (CC) may also be referred to as carrier frequency, cell, frequency carrier, etc.

[0117] The terms “system” and “network” as used in this disclosure are used interchangeably.

[0118] Furthermore, the information, parameters, etc., described in this disclosure can be represented using absolute values, relative values ​​to predetermined values, or other corresponding information. For example, wireless resources can also be indicated using indexes.

[0119] The names used for the above parameters are non-limiting in any respect. Furthermore, the formulas, etc., using these parameters sometimes differ from those explicitly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by all suitable names, therefore the various names assigned to these various channels and information elements are non-limiting in any respect.

[0120] In this disclosure, the terms "base station (BS)," "wireless base station," "base station device," "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. Sometimes, terms such as macro cell, small cell, femtocell, and picocell are also used to refer to base stations.

[0121] A base station can accommodate one or more (e.g., three) cells. When a base station accommodates multiple cells, its coverage area can be divided into several smaller areas, each of which can also provide communication services through a base station subsystem (e.g., a small indoor base station (RRH: Remote Radio Head)). Terms such as "cell" or "sector" refer to a portion or all of the coverage area of ​​at least one of the base station and base station subsystem providing communication services within that coverage area.

[0122] In this disclosure, the base station sending information to the terminal can also be replaced by the base station instructing the terminal on information-based control / actions.

[0123] In this disclosure, the terms "Mobile Station (MS)," "user terminal," "User Equipment (UE)," and "terminal" are used interchangeably.

[0124] For mobile stations, those skilled in the art sometimes also use the following terms: 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, handheld device, user agent, mobile client, client, or some other appropriate terms.

[0125] At least one of the base station and the mobile station can also be referred to as a transmitting device, a receiving device, a communication device, etc. Furthermore, at least one of the base station and the mobile station can also be a device mounted on a mobile body, the mobile body itself, etc. The mobile body refers to an object capable of movement, with an arbitrary speed. It also includes situations where the mobile body is stationary. Examples of mobile bodies include, but are not limited to, vehicles, transport vehicles, automobiles, motorcycles, bicycles, connected cars, excavators, bulldozers, wheel loaders, dump trucks, forklifts, trains, buses, rear cars, rickshaws, ships and other watercraft, airplanes, rockets, artificial satellites, Drone (registered trademark), multi-rotor helicopters, quadcopter helicopters, balloons, and objects mounted on them. Additionally, the mobile body can also be a mobile body that moves autonomously based on operating commands. It can be a means of transportation (e.g., cars, airplanes, etc.), a mobile body moving in an unmanned manner (e.g., drones, self-driving cars, etc.), or a robot (humanized or unmanned). Furthermore, at least one of the base station and the mobile station may also include devices that are not necessarily mobile 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.

[0126] Furthermore, the base station in this disclosure can also be replaced by a user terminal. For example, the communication between the base station and the user terminal can be replaced by communication between multiple terminals 20 (e.g., D2D (Device-to-Device), V2X (Vehicle-to-Everything), etc.), and various forms / implementations of this disclosure can also be applied. In this case, the terminal 20 can also be configured to have the functions of the base station 10 described above. In addition, terms such as "uplink" and "downlink" can be replaced with terms corresponding to communication between terminals (e.g., "side"). For example, uplink channel, downlink channel, etc. can also be replaced with side channel.

[0127] Similarly, the user terminal in this disclosure can also be replaced by a base station. In this case, the base station can also be configured to have the functions of the aforementioned user terminal.

[0128] As used in this disclosure, terms such as "determining" and "determining" sometimes encompass a variety of actions. For example, "determining" or "determining" may include actions such as judging, calculating, computing, processing, deriving, investigating, searching (e.g., searching in a table, database, or other data structure), and ascertaining, which are considered as actions of "determining" or "determining." Furthermore, "determining" or "determining" may include actions such as receiving (e.g., receiving information), transmitting (e.g., sending information), inputting, outputting, and accessing (e.g., accessing data in memory), which are considered as actions of "determining" or "determining." Moreover, "determining" or "determining" may include actions such as resolving, selecting, choosing, establishing, and comparing, which are considered as actions of "determining" or "determining." That is, "judgment" and "decision" can include matters that are considered as having been "judged" or "decided". In addition, "judgment (decision)" can also be replaced by "assuming", "expecting", "considering", etc.

[0129] The terms “connected,” “coupled,” or any variations thereof are intended to indicate any direct or indirect connection or combination between two or more elements, including cases where there is one or more intermediate elements between the two elements that are “connected” or “coupled.” The combination or connection between elements can be physical, logical, or a combination of these. For example, “access” can be used instead of “connected.” In the context of this disclosure, it can be understood that two elements are “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, using electromagnetic energy with wavelengths in the wireless frequency domain, microwave region, and light (including both visible and invisible regions) to “connect” or “couple” to each other.

[0130] The reference signal can be simply called RS (Reference Signal), or, depending on the standard applied, pilot.

[0131] As used in this disclosure, the word "based on" does not mean "based on only" unless otherwise expressly stated. In other words, the word "based on" means both "based on only" and "based on at least".

[0132] Any reference to elements 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 method of distinguishing between two or more elements. Therefore, references to the first and second elements do not imply that only two elements can be taken, or that the first element must precede the second element in any form.

[0133] Alternatively, the "unit" in the structure of the above devices can be replaced with "section", "circuit", "equipment", etc.

[0134] When the terms "include," "including," and their variations are used in this disclosure, these terms, like the term "comprising," imply inclusion. Furthermore, the term "or" as used in this disclosure does not refer to XOR.

[0135] A radio frame can consist of one or more frames in the time domain. In the time domain, one or more frames can be called subframes. A subframe can also consist of one or more time slots in the time domain. A subframe can be a fixed duration (e.g., 1 ms) independent of the parameter set (numerology).

[0136] A parameter set can be communication parameters applied to at least one of the transmission and reception of a signal or channel. For example, a parameter set can 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 processing performed by the transceiver in the frequency domain, and specific windowing processing performed by the transceiver in the time domain.

[0137] In the time domain, a time slot can be composed of one or more symbols (OFDM (Orthogonal Frequency Division Multiplexing) symbols, SC-FDMA (Single Carrier Frequency Division Multiple Access) symbols, etc.). A time slot can be a time unit based on a set of parameters.

[0138] A time slot can contain multiple mini-time slots. Each mini-time slot can consist of one or more symbols in the time domain. Additionally, a mini-time slot can also be called a sub-time slot. A mini-time slot can consist of fewer symbols than a time slot. PDSCH (or PUSCH) transmitted in time units larger than mini-time slots can be called PDSCH (or PUSCH) mapping type (type) A. PDSCH (or PUSCH) transmitted using mini-time slots can be called PDSCH (or PUSCH) mapping type (type) B.

[0139] Radio frames, subframes, time slots, mini-time slots, and symbols all represent time units for transmitting signals. Radio frames, subframes, time slots, mini-time slots, and symbols can each be referred to by other corresponding names.

[0140] For example, a subframe can be called a Transmission Time Interval (TTI), multiple consecutive subframes can also be called a TTI, and a time slot or a mini-time slot can also be called a TTI. That is to say, at least one of a subframe and a TTI can be a subframe (1ms) in existing LTE, a period shorter than 1ms (e.g., symbols 1-13), or a period longer than 1ms. Furthermore, the unit representing TTI may not be called a subframe, but rather a time slot, mini-time slot, etc.

[0141] Here, TTI refers, for example, to the smallest unit of time for scheduling in wireless communication. For instance, in an LTE system, the base station schedules the allocation of radio resources (bandwidth, transmit power, etc., available to each terminal 20) in units of TTI. However, the definition of TTI is not limited to this.

[0142] The Time Interval (TTI) can be a unit of time for transmitting channel-coded data packets (transmission blocks), code blocks, codewords, etc., or it can be a processing unit such as scheduling or link adaptation. Furthermore, when a TTI is given, the actual time interval (e.g., the number of symbols) that the transmission block, code block, codeword, etc., are mapped to can be shorter than the TTI.

[0143] Furthermore, when one time slot or one mini time slot is referred to as a TTI, more than one TTI (i.e., more than one time slot or more than one mini time slot) can become the minimum time unit for scheduling. In addition, the number of time slots (mini time slots) constituting the minimum time unit for scheduling can also be controlled.

[0144] A TTI with a duration of 1ms can also be called a normal TTI (TTI in LTE Rel.8-12), a long TTI, a normal subframe, a long subframe, or a time slot. A TTI shorter than a normal TTI can also be called 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, or a time slot.

[0145] Furthermore, for long TTIs (e.g., normal TTIs, subframes, etc.), they can be replaced with TTIs with a duration of more than 1ms. For short TTIs (e.g., shortened TTIs, etc.), they can be replaced with TTIs with a duration of less than long TTIs but more than 1ms.

[0146] A resource block (RB) is a unit of resource allocation in both 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 based on the parameter set.

[0147] In addition, the time domain of an RB can contain one or more symbols, which can be a time slot, a mini time slot, a subframe, or a TTI in length. A TTI, a subframe, etc., can each be composed of one or more resource blocks.

[0148] In addition, one or more RBs can also be called Physical Resource Block (PRB), Sub-Carrier Group (SCG), Resource Element Group (REG), PRB Pair, RB Pair, etc.

[0149] In addition, a resource block can consist of one or more resource elements (REs). For example, one RE can be a radio resource area consisting of one subcarrier and one symbol.

[0150] The Bandwidth Part (BWP) (also known as partial bandwidth, etc.) can also represent a subset of contiguous common resource blocks (RBs) used for a certain parameter set in a certain carrier. Here, common RBs can be determined by indexing RBs based on a common reference point of that carrier. PRBs can be defined and numbered within a BWP.

[0151] A BWP can include a UL BWP and a DL BWP. One or more BWPs can be set for a UE within a single carrier.

[0152] At least one of the configured BWPs can be active, and the UE may not intend to transmit or receive predetermined signals / channels outside of the active BWP. Furthermore, the terms "cell," "carrier," etc., used in this disclosure can be replaced with "BWP."

[0153] The structures of radio frames, subframes, time slots, mini-time slots, and symbols described above are merely illustrative. For example, the number of subframes contained in a radio frame, the number of time slots in each subframe or radio frame, the number of mini-time slots contained within a time slot, the number of symbols and RBs contained in a time slot or mini-time slot, the number of subcarriers contained in an RB, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, and other structures can be varied in many ways.

[0154] In this disclosure, for example, in cases where articles are added through translation, such as in English (e.g., a, an, and the), this disclosure may also include cases where the noun following these articles is in a plural form.

[0155] In this disclosure, the phrase "A and B are different" can mean "A and B are not the same." Furthermore, this phrase can also mean "A and B are each different from C." Terms such as "separate" and "combined" can also be interpreted in the same way as "different."

[0156] The various forms / implementations described in this disclosure can be used individually or in combination, and can be switched depending on the execution. Furthermore, the notification of predetermined information (e.g., a "It is X" notification) is not limited to being explicit, but can also be implicit (e.g., not notifying the predetermined information).

[0157] The present disclosure has been described in detail above, but it will 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 as modifications and variations without departing from the spirit and scope of the present disclosure as defined by the claims. Therefore, the present disclosure is for illustrative purposes only and is not intended to be limiting.
