Summary of the Invention

Problems to be Solved by the Invention

[0005] In LTE and NR, UE categories or UE capabilities for IoT (Internet of Things) are defined, which reduce the functionality of features that are mandatorily supported by a typical terminal, such as transmit / receive bandwidth and the number of antennas. For example, in LTE, eMTC (enhanced Machine Type Communication) and NB-IoT (Narrow Band IoT) are defined, while in NR, RedCap (Reduced Capability) is defined.

[0006] IoT devices require additional features to compensate for performance degradation due to feature reductions. For example, repeated transmission of PUSCH (Physical Uplink Shared Channel) is being considered to improve coverage. In other words, performance improvement is achieved by increasing resources in the time domain. On the other hand, in environments where IoT devices are installed, it is expected that many devices will be connected, which may impose constraints on the number of users concurrency in the time domain.

[0007] This invention has been made in view of the above points, and aims to efficiently perform repeated transmissions in a wireless communication system. [Means for solving the problem]

[0008] According to the disclosed technology, a terminal is provided having a transmitting unit that transmits an uplink sharing channel to a base station, a control unit that controls the repeated transmission of the uplink sharing channel, and a receiving unit that receives information from the base station regarding whether or not to perform repeated transmission of the uplink sharing channel, wherein if the receiving unit receives the information indicating that repeated transmission of the uplink sharing channel will not be performed, the control unit interrupts the repeated transmission of the uplink sharing channel, and if the receiving unit receives the information indicating that repeated transmission of the uplink sharing channel will be performed, the transmitting unit performs repeated transmission of the uplink sharing channel to the base station. [Effects of the Invention]

[0011] Embodiments of the present invention will be described below with reference to the drawings. Note that the embodiments described below are examples, and the embodiments to which the present invention is applied are not limited to those described below.

[0012] In the operation of the wireless communication system according to the embodiment of the present invention, existing technologies are used as appropriate. However, the existing technology is, for example, existing LTE, but is not limited to existing LTE. In addition, the term "LTE" used in this specification shall have a broad meaning including LTE-Advanced and subsequent systems (e.g., NR) unless otherwise specified.

[0013] 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), PUSCH (Physical Uplink Shared Channel), etc. used in existing LTE are used. This is for convenience of description, and signals, functions, etc. similar to these may be called by other names. Also, the above terms in NR correspond to NR-SS, NR-PSS, NR-SSS, NR-PBCH, NR-PRACH, etc. However, even for signals used in NR, the "NR-" is not necessarily specified.

[0014] In addition, in the embodiments of the present invention, the duplex mode may be a TDD (Time Division Duplex) mode, an FDD (Frequency Division Duplex) mode, or other modes (e.g., Flexible Duplex, etc.).

[0015] In addition, in the embodiments of the present invention, when wireless parameters or the like are "configured", it may mean that predetermined values are pre-configured, or it may mean that wireless parameters notified from the base station 10 or the terminal 20 are configured.

[0016] FIG. 1 is a diagram for explaining a wireless communication system in an embodiment of the present invention. The wireless communication system in the embodiment of the present invention includes a base station 10 and a terminal 20 as shown in FIG. 1. Although one base station 10 and one terminal 20 are shown in FIG. 1, this is an example, and there may be a plurality of each.

[0017] 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 may be defined by the number of OFDM (Orthogonal Frequency Division Multiplexing) symbols, and the frequency domain may be defined by the number of subcarriers or the number of resource blocks. Also, the TTI (Transmission Time Interval) in the time domain may be a slot or a sub-slot, or the TTI may be a sub-frame.

[0018] The base station 10 is capable of performing carrier aggregation in which a plurality of cells (a plurality of CCs (Component Carriers)) are bundled to communicate with the terminal 20. In carrier aggregation, one primary cell (PCell, Primary Cell) and one or more secondary cells (SCell, Secondary Cell) are used.

[0019] The base station 10 transmits synchronization signals and system information to the terminal 20. Synchronization signals include, for example, NR-PSS and NR-SSS. System information is transmitted via, for example, NR-PBCH or PDSCH, and is also called broadcast information. As shown in Figure 1, the base station 10 transmits control signals or data to the terminal 20 via DL (Downlink) and receives control signals or data from the terminal 20 via UL (Uplink). Here, signals transmitted via control channels such as PUCCH and PDCCH are called control signals, and signals transmitted via shared channels such as PUSCH and PDSCH are called data, but this is just one example of terminology.

[0020] Terminal 20 is a communication device equipped with wireless communication capabilities, such as a smartphone, mobile phone, tablet, wearable device, or M2M (Machine-to-Machine) communication module. As shown in Figure 1, Terminal 20 receives control signals or data from the base station 10 via DL and transmits control signals or data to the base station 10 via UL, thereby utilizing various communication services provided by the wireless communication system. Terminal 20 may also be referred to as UE, and base station 10 as gNB.

[0021] Terminal 20 is capable of performing carrier aggregation, which involves bundling multiple cells (multiple CCs) together to communicate with base station 10. Carrier aggregation uses one primary cell and one or more secondary cells. A PUCCH-SCell with PUCCH may also be used.

[0022] Here, LTE and NR define UE categories or UE capabilities for IoT (Internet of Things) that reduce the functionality of a typical terminal, such as transmission / reception bandwidth and number of antennas. For example, LTE defines eMTC (enhanced Machine Type Communication) and NB-IoT (Narrow Band IoT), while NR defines RedCap (Reduced Capability).

[0023] IoT devices require additional features to compensate for performance degradation due to feature reductions. PUSCH is one of the channels that can become a coverage bottleneck, and improvements to PUSCH's characteristics are being considered. For example, repeated transmission of PUSCH is being considered to improve coverage.

[0024] In other words, performance improvements are achieved by increasing resources in the time domain. On the other hand, in environments where IoT devices are installed, it is expected that a large number of devices will be connected, which may impose limitations on the number of user multiplexing connections in the time domain. Furthermore, it may become necessary to perform more user multiplexing in the frequency domain or spatial domain.

[0025] Therefore, considering coverage characteristics and the connection of numerous terminals, repeated transmissions in the time direction may be canceled as needed.

[0026] Figure 2 shows an example (1) of repeated transmission in an embodiment of the present invention. To improve coverage characteristics, a large number of repeated transmissions in the time direction (repetition) are assumed. Here, as shown in Figure 2, it is assumed that decoding of the PUSCH is successful before the set number of repeated transmissions of PUSCH are transmitted. In this case, as shown in Figure 2, repeated transmission of the PUSCH after successful decoding of the PUSCH may be canceled, and resources may be allocated to other data or other terminals 20. For example, repeated transmission of the PUSCH may be canceled using a specific DCI (Downlink Control Information) format. For example, cancellation of repeated transmission may be instructed using DCI format 2_4 (see Non-Patent Literature 2).

[0027] Figure 3 shows an example (2) of repeated transmission in an embodiment of the present invention. As shown in Figure 3, repeated transmission of PUSCH may be canceled when UL slots are consecutive. For example, it is assumed that UL slots are consecutive during FD (Full duplex) operation. Note that the position of repeated transmission of PUSCH that is successfully decoded shown in Figure 3 is an example, and it may be at other positions, for example, two slots before repeated transmission of PUSCH is canceled.

[0028] In consecutive UL slots, the time resource at the end of the PUSCH slot may be allocated to ACK / NACK feedback sent via DL in order to cancel UL transmissions such as repeated transmissions configured for purposes such as coverage expansion. Alternatively, the time resource at the beginning of the PUSCH slot may be used to indicate whether or not to allow the PUSCH transmission in order to cancel the UL transmission. Furthermore, the device's capabilities may be reported to the network in order to cancel the UL transmission.

[0029] Figure 4 shows an example (3) of repeated transmission in an embodiment of the present invention. As shown in Figure 4, the time resource at the end of the PUSCH slot may be the ACK / NACK feedback transmitted via DL. The base station 10 may send ACK / NACK feedback to the terminal 20 to notify whether the PUSCH was successfully received or not. As an example of resource configuration, as shown in Figure 4, the PUSCH resource may be placed at the beginning of the slot and the ACK / NACK feedback resource may be placed at the end of the slot.

[0030] The ACK / NACK feedback may correspond to a PUSCH in the same slot, or, considering the processing time at base station 10, it may correspond to a PUSCH in a slot prior to that slot. For example, the ACK / NACK feedback may correspond to whether or not a PUSCH was received in the slot one slot prior to the slot where the ACK / NACK feedback is placed.

[0031] As shown in Figure 4, the push of UL and the ACK / NACK feedback of DL may be placed on the same frequency resource, or they may be placed on different frequency resources, as shown in Figure 5 later.

[0032] The base station 10 does not always transmit ACK / NACK feedback. It may transmit ACK / NACK feedback periodically, for example, once every two PUSCH transmissions, or it may transmit ACK / NACK feedback only when necessary, for example, when transmitting ACK.

[0033] To ensure sufficient switching time from DL to UL in terminal 20, the first symbol of the slot may be assigned to the switching time. Furthermore, when terminal 20 is operating in FD mode, the resources for PUSCH and the resources for ACK / NACK feedback may overlap in the time and / or frequency directions.

[0034] Terminal 20 does not need to perform any further PUSCH transmissions if it receives an ACK. Alternatively, terminal 20 may continue sending PUSCH transmissions if it receives a NACK. Alternatively, terminal 20 may continue sending PUSCH transmissions until it receives an ACK, regardless of whether or not it receives feedback. Alternatively, terminal 20 may send a PUSCH transmission only if it receives a NACK, regardless of whether or not it receives feedback.

[0035] Figure 5 shows an example (4) of repeated transmission in an embodiment of the present invention. As shown in Figure 5, the UL PUSCH and the DL ACK / NACK feedback may be placed on different frequency resources, and the time resource at the end of the PUSCH slot may be used for the ACK / NACK feedback transmitted by DL.

[0036] Figure 6 shows an example (5) of repeated transmission in an embodiment of the present invention. As shown in Figure 6, the time resource at the beginning of the PUSCH slot may indicate whether or not to perform a PUSCH transmission using DL. The base station 10 may send a transmission notification (Tx indication) to the terminal 20 informing whether or not a PUSCH transmission is necessary. As an example of resource configuration, as shown in Figure 6, a DL channel for notifying whether or not to perform a PUSCH transmission may be placed at the beginning of the slot, and the PUSCH resource may be placed immediately after that slot. The transmission notification may be information indicating that a PUSCH transmission is necessary, or information indicating that a PUSCH transmission is unnecessary. Furthermore, the transmission notification may only indicate that a PUSCH transmission is necessary or unnecessary, or only one of the two.

[0037] A PUSCH transmission notification may be an instruction corresponding to a PUSCH transmission in the same slot, or it may be an instruction corresponding to a PUSCH transmission in a later slot, taking into account the processing time at the mobile station 20. For example, a PUSCH transmission notification may correspond to a PUSCH transmission one slot later.

[0038] As shown in Figure 6, the UL PUSCH and the DL transmission notification may be placed on the same frequency resource, or they may be placed on different frequency resources, as shown in Figure 7 later.

[0039] The base station 10 does not always send transmission notifications. It may send transmission notifications periodically, for example, once every two PUSCH signals received, or it may send transmission notifications only when necessary, for example, only when a PUSCH transmission is required.

[0040] To ensure sufficient switching time from DL to UL in terminal 20, a symbol for the switching time may be assigned between the transmission notification channel and the PUSCH resource. Furthermore, if terminal 20 is operating in FD mode, the PUSCH resource and the transmission notification channel resource may overlap in the time and / or frequency directions.

[0041] Terminal 20 may perform a PUSCH transmission only if it receives a transmission notification indicating that a PUSCH transmission is required. Alternatively, terminal 20 may refrain from performing a PUSCH transmission if it receives a transmission notification indicating that a PUSCH transmission is not required. Alternatively, terminal 20 may continue performing PUSCH transmissions regardless of whether or not it receives a transmission notification, until it receives a transmission notification indicating that a PUSCH transmission is not required.

[0042] Figure 7 shows an example (6) of repeated transmission in an embodiment of the present invention. As shown in Figure 7, the UL PUSCH and the DL transmit notification may be placed on different frequency resources, and the time resource at the beginning of the PUSCH slot may be used as the channel for the transmit notification transmitted by DL.

[0043] Furthermore, terminal 20 may report the UE capabilities shown in 1)-3) below to the network.

[0044] 1) UE capability related to the ability to handle cancellation of PUSCH transmissions. For example, this may be a UE capability indicating whether or not FD operation is supported. For example, this may be a UE capability indicating whether or not transmission cancellation by PUSCH ACK / NACK feedback is supported. For example, this may be a UE capability indicating whether or not PUSCH transmission by PUSCH transmission notification is supported.

[0045] 2) UE capability indicating which frequencies support push transmission cancellation. For example, this could be a UE capability that indicates collectively whether or not push transmission cancellation is supported for all frequencies. For example, this could be a UE capability that indicates whether or not push transmission cancellation is supported as a mobile station. For example, this could be a UE capability that indicates whether or not push transmission cancellation is supported for each frequency. For example, this could be a UE capability that indicates whether or not push transmission cancellation is supported for each frequency band, such as FR1 and FR2.

[0046] 3) UE capability related to duplexing schemes that support cancellation of push transmissions. For example, this may be a UE capability indicating whether or not a mobile station supports cancellation of push transmissions. For example, this may be a UE capability indicating whether or not each duplexing scheme supports cancellation of push transmissions. The duplexing scheme may be, for example, TDD, FDD, or FD.

[0047] In the embodiment described above, when terminal 20 repeatedly sends PUSCH messages, it can effectively utilize the available resources by canceling repeated transmissions as needed.

[0048] In other words, it enables efficient repeated transmission in wireless communication systems.

[0049] (Device configuration) Next, we will describe an example of the functional configuration of the base station 10 and terminal 20 that perform the processes and operations described above. The base station 10 and terminal 20 include functions to perform the embodiments described above. However, the base station 10 and terminal 20 may each have only one of the functions from the embodiments.

[0050] <Base station 10> Figure 8 shows an example of the functional configuration of a base station 10. As shown in Figure 8, the base station 10 has a transmitting unit 110, a receiving unit 120, a setting unit 130, and a control unit 140.

The signal transmission function of the control unit 240 may be included in the transmission unit 210, and the signal reception function of the control unit 240 may be included in the reception unit 220. The transmission unit 210 and the reception unit 220 may also be called the transmitter and receiver, respectively.

[0056] (Hardware configuration) The block diagrams (Figures 8 and 9) used in the description of the above embodiments show functional units. These functional blocks (components) are realized by any combination of at least one of hardware and software. Furthermore, the method of realizing each functional block is not particularly limited. That is, each functional block may be realized using one device that is physically or logically coupled, or it may be realized using two or more physically or logically separated devices that are directly or indirectly connected (for example, using wired or wireless connections). A functional block may be realized by combining the above one device or the above multiple devices with software.

It may also apply to a combination of multiple systems (for example, a combination of at least one of LTE and LTE-A with 5G).

[0090] The processing procedures, sequences, flowcharts, etc., of each aspect / embodiment described herein may be reordered, provided they are consistent with each other. For example, the methods described herein present various step elements in an exemplary order and are not limited to that specific order.

[0091] In this specification, specific operations performed by the base station 10 may, in some cases, be performed by its upper node. In a network consisting of one or more network nodes having a base station 10, it is clear that various operations performed for communication with the terminal 20 can be performed by the base station 10 and at least one of the other network nodes (for example, an MME or S-GW, but not limited to these). Although the above example illustrates the case where there is one other network node besides the base station 10, the other network node may be a combination of multiple other network nodes (for example, an MME and an S-GW).

[0092] The information or signals described in this disclosure may be output from a higher layer (or lower layer) to a lower layer (or higher layer). They may also be input and output via multiple network nodes.

[0093] Input and output information may be stored in a specific location (e.g., memory) or managed using a management table. Input and output information may be overwritten, updated, or appended to. Output information may be deleted. Input information may be transmitted to other devices.

[0094] The determination in this disclosure may be made by a value represented by one bit (0 or 1), by a boolean value (true or false), or by a numerical comparison (for example, a comparison with a predetermined value).

[0095] Software should be broadly interpreted to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions, and so on, whether they are called software, firmware, middleware, microcode, hardware description languages, or by any other name.

[0096] Furthermore, software, instructions, information, etc., may be transmitted and received via a transmission medium. For example, if software is transmitted from a website, server, or other remote source using at least one of wired technology (such as coaxial cable, fiber optic cable, twisted pair, or digital subscriber line (DSL)) and wireless technology (such as infrared or microwave), then at least one of these wired and wireless technologies is included in the definition of a transmission medium.

[0097] The information, signals, etc. described in this disclosure may be represented using any of the various different techniques. For example, the data, instructions, commands, information, signals, bits, symbols, chips, etc. that may be referred to throughout the above description may be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, optical fields or photons, or any combination thereof.

[0098] In addition, terms used in this disclosure and terms necessary for understanding this disclosure may be replaced with terms having the same or similar meanings. For example, at least one of the channel and symbol may be a signal (signaling). Also, a signal may be a message. Furthermore, a component carrier (CC) may be called a carrier frequency, cell, frequency carrier, etc.

[0099] The terms “system” and “network” as used in this disclosure are interchangeable.

[0100] Furthermore, the information, parameters, etc., described in this disclosure may be expressed using absolute values, relative values ​​from a given value, or other corresponding information. For example, wireless resources may be indicated by an index.

[0101] The names used for the parameters described above are not restrictive in any way. Furthermore, the formulas and other expressions using these parameters may differ from those expressly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by any suitable name, and therefore, the various names assigned to these various channels and information elements are not restrictive in any way.

[0102] In this disclosure, terms such as "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", and "component carrier" may be used interchangeably. Base stations may also be referred to by terms such as macrocell, small cell, femtocell, and picocell.

[0103] A base station can accommodate one or more (e.g., three) cells. If a base station accommodates multiple cells, the entire coverage area of ​​the base station can be divided into several smaller areas, each of which may also be provided with communication services by a base station subsystem (e.g., a Remote Radio Head (RRH)). The terms “cell” or “sector” refer to part or all of the coverage area of ​​at least one of the base station and / or base station subsystems that provide communication services in that coverage.

[0104] In this disclosure, terms such as "Mobile Station (MS)," "user terminal," "User Equipment (UE)," and "terminal" may be used interchangeably.

[0105] A mobile station may also be referred to by those skilled in the art as a 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 several other appropriate terms.

[0106] At least one of the base station and the mobile station may be called a transmitting device, a receiving device, a communication device, etc. At least one of the base station and the mobile station may be a device mounted on a mobile body, the mobile body itself, etc. The mobile body may be a vehicle (e.g., a car, an airplane, etc.), an unmanned mobile body (e.g., a drone, an autonomous vehicle, etc.), or a robot (manned or unmanned). At least one of the base station and the mobile station may be a device that does not necessarily move during communication operation. 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.

[0107] Furthermore, the term "base station" in this disclosure may be interpreted as "user terminal." For example, the various aspects / embodiments of this disclosure may be applied to a configuration in which communication between a base station and a user terminal is replaced with communication between multiple terminals 20 (which may be called, for example, D2D (Device-to-Device), V2X (Vehicle-to-Everything), etc.). In this case, the terminals 20 may have the functions that the base station 10 has. Also, terms such as "uplink" and "downlink" may be interpreted as terms corresponding to terminal-to-terminal communication (for example, "side"). For example, uplink channel, downlink channel, etc., may be interpreted as side channel.

[0108] Similarly, the term "user terminal" in this disclosure may be replaced with "base station." In this case, the base station may be configured to have the same functions as the user terminal described above.

[0109] As used in this disclosure, the terms “determining” and “determining” may encompass a wide variety of actions. “Determining” may include, for example, judging, calculating, computing, processing, deriving, investigating, looking up, searching, inquiry (e.g., searching in a table, database, or other data structure), and ascertaining. “Determining” may also include, for example, receiving (e.g., receiving information), transmitting (e.g., sending information), input, output, and accessing (e.g., accessing data in memory). Furthermore, "judgment" and "decision" can include considering something as having been "judged" or "decided" after resolving, selecting, choosing, establishing, comparing, etc. In other words, "judgment" and "decision" can include considering something as having been "judged" or "decided" after some action. Also, "judgment (decision)" can be reinterpreted as "assuming," "expecting," or "considering."

[0110] The terms “connected,” “coupled,” or any variation thereof, mean any direct or indirect connection or coupling between two or more elements, and may include the presence of one or more intermediate elements between two elements that are “connected” or “coupled” with each other. The coupling or connection between elements may be physical, logical, or a combination thereof. For example, “connection” may be reinterpreted as “access.” As used in this disclosure, two elements may be considered to be “connected” or “coupled” with each other using at least one of one or more wires, cables, and printed electrical connections, and, in some non-limiting and non-exclusive examples, electromagnetic energy having wavelengths in the radio frequency domain, microwave domain, and optical (both visible and invisible) domain.

[0111] The reference signal can also be abbreviated as RS (Reference Signal), and may be called a pilot depending on the applicable standard.

[0112] In this disclosure, the phrase "based on" does not mean "based solely on" unless otherwise specified. In other words, the phrase "based on" means both "based solely on" and "based at least on."

[0113] Any reference to elements using the designations “first,” “second,” etc., as used in this disclosure does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient way to distinguish between two or more elements. Accordingly, references to the first and second elements do not imply that only two elements may be employed, or that the first element must precede the second element in any way.

[0114] In the configuration of each of the above devices, "means" may be replaced with "part," "circuit," "device," etc.

[0115] Where the terms “include,” “including,” and variations thereof are used in this disclosure, these terms are intended to be inclusive, as is the term “comprising.” Furthermore, the term “or” as used in this disclosure is not intended to mean exclusive OR.

[0116] A wireless frame may consist of one or more frames in the time domain. Each of these frames in the time domain may be called a subframe. A subframe may further consist of one or more slots in the time domain. A subframe may have a fixed time length (e.g., 1 ms) that is independent of numerology.

[0117] Numerical logic may be communication parameters applied to at least one of the transmission and reception of a signal or channel. Numerical logic may include, for example, 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 configuration, specific filtering processes performed by the transceiver in the frequency domain, and specific windowing processes performed by the transceiver in the time domain.

[0118] A slot may consist of one or more symbols in the time domain (such as OFDM (Orthogonal Frequency Division Multiplexing) symbols, SC-FDMA (Single Carrier Frequency Division Multiple Access) symbols, etc.). A slot may also be a time unit based on neurology.

[0119] A slot may include multiple minislots. Each minislot may consist of one or more symbols in the time domain. Minislots may also be called subslots. Minislots may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a minislot may be called PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a minislot may be called PDSCH (or PUSCH) mapping type B.

[0120] Wireless frames, subframes, slots, minislots, and symbols all represent units of time when transmitting a signal. Different names may be used for each of these terms.

[0121] For example, one subframe may be called a Transmission Time Interval (TTI), multiple consecutive subframes may be called a TTI, or one slot or one mini-slot may be called a TTI. In other words, at least one of a subframe and a TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (e.g., 1-13 symbols), or a period longer than 1 ms. Note that the unit representing the TTI may be called a slot, mini-slot, etc., instead of a subframe.

[0122] Here, TTI refers to, for example, the smallest unit of time for scheduling in wireless communication. For example, in an LTE system, the base station schedules each terminal 20 to allocate wireless resources (such as the frequency bandwidth and transmission power available to each terminal 20) in TTI units. However, the definition of TTI is not limited to this.

[0123] TTI may be a transmission time unit for channel-encoded data packets (transport blocks), code blocks, code words, etc., or it may be a processing unit for scheduling, link adaptation, etc. Given a TTI, the actual time interval (e.g., number of symbols) to which the transport block, code block, code word, etc. are mapped may be shorter than the given TTI.

[0124] Furthermore, if one slot or one mini-slot is referred to as TTI, then one or more TTIs (i.e., one or more slots or one or more mini-slots) may constitute the minimum time unit of scheduling. In addition, the number of slots (number of mini-slots) that constitute the minimum time unit of scheduling may be controlled.

[0125] A TTI with a time length of 1ms may also be called a normal TTI, long TTI, normal subframe, long subframe, slot, etc. A TTI shorter than a normal TTI may also be called a shortened TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, mini slot, sub slot, slot, etc.

[0126] Furthermore, long TTIs (e.g., normal TTIs, subframes, etc.) may be interpreted as TTIs with a time length exceeding 1 ms, and short TTIs (e.g., shortened TTIs, etc.) may be interpreted as TTIs with a TTI length less than that of a long TTI but 1 ms or more.

[0127] A resource block (RB) is a resource allocation unit in the time domain and frequency domain, and in the frequency domain, it may contain one or more consecutive subcarriers. The number of subcarriers in an RB may be the same regardless of the neurology, for example, 12. The number of subcarriers in an RB may be determined based on the neurology.

[0128] Furthermore, the time domain of RB may contain one or more symbols and may be the length of one slot, one minislot, one subframe, or one TTI. One TTI, one subframe, etc., may each consist of one or more resource blocks.

[0129] One or more RBs may also be called a Physical RB (PRB), Sub-Carrier Group (SCG), Resource Element Group (REG), PRB pair, RB pair, etc.

[0130] Furthermore, a resource block may consist of one or more resource elements (REs). For example, one RE may be a radio resource area comprising one subcarrier and one symbol.

[0131] A Bandwidth Part (BWP), also known as a partial bandwidth, may represent a subset of consecutive common resource blocks (RBs) for a particular neurology system in a given carrier. These common RBs may be identified by an index of the RBs relative to a common reference point of the carrier. A Bandwidth Part (PRB) may be defined and numbered within a given BWP.

[0132] A BWP may include a BWP for UL (Ultraviolet Link) and a BWP for DL ​​(Download Link). One or more BWPs may be set for a terminal 20 within a single carrier.

[0133] At least one of the configured BWPs may be active, and terminal 20 does not need to be expected to send or receive a predetermined signal / channel outside of the active BWP. In this disclosure, terms such as "cell" and "carrier" may be read as "BWP".

[0134] The structures described above, such as wireless frames, subframes, slots, minislots, and symbols, are merely illustrative. For example, the number of subframes included in a wireless frame, the number of slots per subframe or wireless frame, the number of minislots included in a slot, the number of symbols and RBs included in a slot or minislot, the number of subcarriers included in an RB, and the number of symbols, symbol length, and cyclic prefix (CP) length within a TTI can be varied in various ways.

[0135] In this disclosure, if articles are added through translation, such as a, an, and the in English, this disclosure may include the fact that the noun following these articles is plural.

[0136] In this disclosure, the term "A and B are different" may mean "A and B are different from each other." The term may also mean "A and B are each different from C." Terms such as "separate" and "combine" may be interpreted similarly to "different."

[0137] Each aspect / embodiment described herein may be used individually, in combination, or switched between as needed during implementation. Furthermore, notification of specific information (e.g., notification that "X is") is not limited to explicit notification, but may also be implicit (e.g., by not providing such notification).

[0138] Although the present disclosure has been described in detail above, 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 in modified and altered forms without departing from the intent and scope of the present disclosure as defined by the claims.
