[0027] Hereinafter, the embodiments of the present application will be described with reference to the accompanying drawings. Note that the embodiments described below are merely examples, and the embodiments of the present application are not limited to the following embodiments.

[0028] In the operation of the wireless communication system according to the embodiment of the present application, a conventional technology is appropriately used. Among them, the conventional technology is, for example, the existing LTE, but is not limited to the existing LTE. In addition, unless otherwise specified, the term "LTE" used in this specification has a broad meaning including LTE-Advanced and the following modes (for example, wireless specifications of NR, 6G) of LTE-Advanced.

[0029] In addition, in the embodiments of the present application 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), PUSCH (Physical Uplink Shared Channel) and the like used in the existing LTE are used. These are for ease of description, and the same signals, functions and the like can 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 and the like. However, even for signals for NR, "NR-" is not necessarily explicitly described.

[0030] Moreover, in the embodiment of the present application, the duplex (Duplex) system can be a TDD (Time Division Duplex: Time Division Duplex) system, an FDD (Frequency Division Duplex: Frequency Division Duplex) system, or another system (for example, a flexible duplex (Flexible Duplex) system, and the like).

[0031] Moreover, in the embodiment of the present application, the "configure" wireless parameters and the like can be pre-configured (Pre-configure) predetermined values, or can be configured wireless parameters notified from the base station 10 or the terminal 20.

[0032] Figure 1 is a diagram illustrating an example of a structure of a wireless communication system in the embodiment of the present application. As Figure 1 indicated, the wireless communication system in the embodiment of the present application includes the base station 10 and the terminal 20. In Figure 1 , one base station 10 and one terminal 20 are each illustrated, but this is merely an example, and a plurality of each can be provided.

[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 in the time domain and the frequency domain, the time domain can be defined by the number of OFDM (Orthogonal Frequency Division Multiplexing: 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 transmits a synchronization signal and system information to the terminal 20. The synchronization signal is, for example, an NR-PSS and an NR-SSS. The system information is transmitted, for example, by an NR-PBCH, and is also referred to as broadcast information. The synchronization signal and the system information can also be referred to as an SSB (SS / PBCH block: SS / PBCH block). As Figure 1As shown, the base station 10 transmits a control signal or data to the terminal 20 through a DL (Downlink), and receives a control signal or data from the terminal 20 through a UL (Uplink). The base station 10 and the terminal 20 each can perform beamforming to perform transmission and reception of signals. In addition, the base station 10 and the terminal 20 each can apply communication based on MIMO (Multiple Input Multiple Output) to the DL or the UL. In addition, the base station 10 and the terminal 20 each can communicate via a secondary cell (SCell) and a primary cell (PCell) based on CA (Carrier Aggregation). Also, the terminal 20 can communicate via a primary cell of the base station 10 and a primary SCG cell (PSCell) of another base station 10 based on DC (Dual Connectivity).

[0034] The terminal 20 is a communication device having a wireless communication function such as a smartphone, a mobile phone, a tablet, a wearable terminal, a communication module for M2M (Machine-to-Machine), and the like. As shown, the terminal 20 receives a control signal or data from the base station 10 through a DL, and transmits a control signal or data to the base station 10 through a UL, thereby utilizing various communication services provided by a wireless communication system. In addition, the terminal 20 receives various reference signals transmitted from the base station 10, and performs measurement of a propagation path quality based on a reception result of the reference signals. Figure 1

[0035] The terminal 20 can perform carrier aggregation that bundles a plurality of cells (a plurality of CCs (Component Carriers)) to communicate with the base station 10. In the carrier aggregation, one PCell (Primary cell) and one or more SCells (Secondary cells) are used. In addition, a PUCCH-SCell having a PUCCH can be used.

[0036] With the spread of a wide variety of devices such as IoT terminals, methods of charging or replacing batteries of a large number of terminals are being studied. With respect to power supply methods to various devices including IoT terminals, attention to a power supply technology using wireless (WPT (Wireless Power Transfer)) has increased in recent years, and research is actively being conducted.

[0037] ​In the IoT terminal, from the viewpoint of cost, the viewpoint of battery replacement, in the handheld terminal, from the viewpoint of cost, the viewpoint of terminal size or shape, wireless power supply is being studied. If efficient, high-capacity wireless power supply can be performed, further sophistication and diversification of terminals can be expected.

[0038] For example, a frequency band specific to wireless power supply distribution is being studied, and the effects on the human body, wave interference with other communication devices, and the like are verified, and in the case where there are no problems, the use range is expanded to the outdoors, a space where people are present.

[0039] In addition, in 3GPP (registered trademark), standardization research of a super power saving terminal that is premised on power supply by a surrounding environment such as sunlight, wind, water, electromagnetic waves, heat, sound, vibration, or the like, or wireless power supply is being conducted. By realizing wireless power supply, charging based on a battery, charging using a wire, or battery replacement is not necessary.

[0040] The terminal 20 can also be supplied with power wirelessly from the base station 10 or the power transmission device 30 connected to the base station 10. The base station 10 or the like that transmits power and the base station 10 or the like that transmits and receives data can be the same or different for the terminal 20.

[0041] As for the device that performs power supply, that is, the power transmission device 30, the following 1) to 3) can be provided.

[0042] 1) The type of the power transmission device 30 can be a device corresponding to a base station, an IAB (Integrated Access Backhaul), a repeater, an RIS (Reconfigurable Intelligent Surface), a TRP (transmission / reception point), or a terminal, or the function of the device for power transmission can be specified separately.

[0043] 2) It can be assumed that the base station, the IAB, the repeater, the RIS, the TRP, or the terminal or the like that performs wireless power supply has a full duplex function.

[0044] 3) The IAB, the repeater, the RIS, the TRP, or the terminal or the like that performs wireless power supply can be in a state of being connected to the base station at the time of power supply, or can be in a state of not being connected at the time of power supply.

[0045] In addition, the power transmission device, the base station, the IAB, the repeater, the RIS, the TRP, or the terminal can be replaced with each other.

[0046] As for the terminal 20 that is supplied with power, the following 1) to 3) can be provided.

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

[0048] 2) It may or may not have the ability to connect to base stations, IABs, repeaters, RIS, TRPs or terminals for data communication.

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

[0050] Figure 2 This is a diagram illustrating a structural example (1) of wireless power supply according to an embodiment of the present invention. Figure 2 As shown, the power supply device 30 can be installed separately from the base station 10 to provide wireless power to the terminal 20. The base station 10 can communicate with the terminal 20 and control the wireless power supply based on the power supply device 30. The power supply device 30 can be installed indoors on walls, ceilings, etc., and outdoors on utility poles, streetlights, etc. In addition, the terminal 20 can also act as the power supply device 30 to provide wireless power to other terminals 20. Hereinafter, providing wireless power to the terminal 20 from the power supply device 30, which is not included in the base station 10, will also be described as providing wireless power to the terminal 20 from the base station 10.

[0051] Figure 3 This is a diagram illustrating a structural example (2) of wireless power supply according to an embodiment of the present invention. Figure 3 As shown, the power supply device 30 can also be installed together with the base station 10 to provide wireless power to the terminal 20. The base station 10 can communicate with the terminal 20 to control the wireless power supply based on the power supply device 30. Hereinafter, the wireless power supply from the power supply 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] In this wireless power supply, to compensate for the reduced transmission efficiency, it is envisioned that power be transmitted at a higher transmission power compared to conventional wireless communication systems. Therefore, depending on the method and frequency of wireless power supply, interference with coexisting wireless communication systems is possible. By controlling the wireless power supply based on power and communication conditions, excellent power and communication quality can be achieved; however, the details of the process for reporting feedback information related to wireless power supply are still unclear.

[0053] Therefore, the terminal 20 that receives power wirelessly from the power supply equipment 30 can also report information related to the power supply status to the base station 10.

[0054] Figure 4is a timing chart for explaining an example of wireless power feeding of an embodiment of the present application. In step S101, the base station 10 transmits a notification related to power feeding to the terminal 20. In the next step S102, the terminal 20 receives wireless power feeding from the power feeding device 30 based on the notification. In the next step S103, the terminal 20 transmits a report related to power feeding to the base station 10.

[0055] The information reported from the terminal 20 to the base station 10 can be the information shown in 1a) - 1d) below.

[0056] 1a) can be the power [W], average power [W], and / or energy [Wh] involved in the power feeding performed in a certain time interval T. The start timing of the certain time interval T can be the start of power feeding, the last report, or a designated timing. The end timing of the certain time interval T can be just before the report, a designated timing, or a timing at which T has elapsed from the start timing. Hereinafter, the definition of the certain time interval T is the same as below. The range and / or granularity of the reported value can be defined in advance or can be set. Furthermore, the reported content can be an index corresponding to the reported value, and the correspondence between the reported value and the index can be defined in advance or can be set. For example, the index Z1 can be reported in the case where the reported value is X1 or more and less than X2, and the index Z2 can be reported in the case where the reported value is X2 or more and less than X3.

[0057] 1b) can also be information indicating whether the power feeding performed in the certain time interval T satisfies a certain condition. It can also be information indicating whether the power [W], average power [W], and / or energy [Wh] involved in the power feeding performed in the certain time interval T exceeds a predetermined value. With respect to the power feeding performed in the certain time interval T, it can also be information indicating whether power feeding has been accepted for a certain time interval T2 or more. The predetermined value and the certain time interval T2 can be defined in advance or can be set. The information indicating whether the power feeding performed in the certain time interval T satisfies a certain condition can also be reported from the terminal 20 to the base station 10 as ACK (for example, a bit value of 1) or NACK (for example, a bit value of 0).

[0058] 1c) can also be information indicating how much power feeding is left to be accepted. For example, the information can be energy [Wh]. For example, the information can also be the remaining battery capacity or insufficient battery capacity at the time of the report.

[0059] 1d) can also be information indicating the result of a quality measurement related to the power feeding beam.

[0060] Through the above-described actions, the terminal 20 can report information related to the result of the power feeding performed, and the base station 10 can appropriately control the power feeding actions thereafter.

[0061] The reporting of information related to the power supply status can be performed at timings shown in 2a) - 2f) below.

[0062] 2a) The reporting of information related to the power supply status can be performed periodically. Figure 5 is a diagram for explaining Example (1) of wireless power supply of an embodiment of the present application. As shown in Figure 5 The periodic resource in which the reporting of information related to the power supply status is performed can also be set from the base station 10. The terminal 20 can start the power supply when receiving a power supply trigger to start the power supply from the base station 10, and can further start the reporting of information related to the power supply status. The power supply trigger transmitted from the base station 10 to the terminal 20 can include information indicating the periodic resource, or the periodic resource can be set in advance. The terminal 20 can report the information related to the power supply status to the base station 10 only in the interval from the start of the power supply to the end of the power supply. In addition, the terminal 20 can continue the reporting after starting the reporting of information related to the power supply status, regardless of the presence or absence of the power supply, until the setting of the reporting of information related to the power supply status is changed.

[0063] 2b) The reporting of information related to the power supply status can also be performed semi-persistently. The periodic resource in which the terminal 20 reports the information related to the power supply status to the base station 10 based on the setting or notification of activation or deactivation (release) can also be set by the base station 10. The terminal 20 can periodically report the information related to the power supply status to the base station 10 during the period from being activated to being deactivated. The terminal 20 can transmit ACK or NACK to the base station 10 when receiving a deactivation command. The activation or deactivation can also be notified to the terminal 20 by DCI or MAC-CE (Medium Access Control-Control Element). The terminal 20 can report the information related to the power supply status to the base station 10 only in the interval from the start of the power supply to the end of the power supply. In addition, the terminal 20 can continue the reporting based on the activation and deactivation after starting the reporting of information related to the power supply status, regardless of the presence or absence of the power supply.

[0064] 2c) The reporting of information related to the power supply status can also be performed aperiodically. Figure 6 is a diagram for explaining Example (2) of wireless power supply of an embodiment of the present application. As shown in Figure 6 The reporting and the resource used in the reporting can also be instructed from the base station 10, and the terminal 20 can aperiodically perform the information related to the power supply status in the resource. As shown in Figure 6As illustrated, the terminal 20 can also report the information on the power supply status to the base station 10 each time the power supply is performed by the power supply trigger. Further, the terminal 20 can also report the information on the power supply status to the base station 10 at a timing determined by the terminal 20 itself based on a specific condition.

[0065] 2d) The reporting timing and / or resource can be specified in the notification on the power supply implementation, and the activation of the reporting can also be performed. For example, Figure 5 or Figure 6 The power supply trigger as illustrated can also be the notification on the power supply implementation. The terminal 20 can also start or perform the power supply based on the notification on the power supply implementation.

[0066] 2e) The terminal 20 can assume that the time between the indication of the reporting, the activation of the reporting, or the end timing of the measurement target (for example, the end timing of the power supply) and the execution of the reporting is equal to or more than a predetermined value. The predetermined value can be specified or determined based on the UE processing time, for example.

[0067] 2f) The reporting can also be performed in a case where the power supply status satisfies a predetermined condition. In addition, the reporting can also be performed in a case where the power supply status does not satisfy a predetermined condition.

[0068] Through the above-described actions, the reporting timing is commonly understood between the base station and the UE.

[0069] The signal for the reporting of the information on the power supply status can be any one of 1) to 3) as illustrated below.

[0070] 1) As one of UCI, HARQ (Hybrid automatic repeat request) - ACK, SR (Scheduling request), or CSI (Channel state information), the reporting of the information on the power supply status can be transmitted via PUCCH or PUSCH.

[0071] 2) As a payload of a higher layer, the reporting of the information on the power supply status can be transmitted via PUSCH.

[0072] 3) The reporting of the information on the power supply status can be transmitted via an SR (PUCCH), SRS, or PRACH resource for the reporting of the information on the power supply status.

[0073] The information on the power supply status can also be transmitted multiplexed with other information as 4a) to 4c) as illustrated below.

[0074] 4a) In a case where the information on the power supply status is transmitted as one of HARQ-ACK, the information on the power supply status can also be included in the generation of the HARQ-ACK codebook. Multiplexing can be performed as well as the HARQ-ACK of the PDSCH that is dynamically scheduled, and DAI (Downlink Assignment Index) can be included in the reporting instruction signal. Counting of the DAI can be performed without distinction from the HARQ-ACK of the PDSCH that is dynamically scheduled. Alternatively, multiplexing can be performed as well as the HARQ-ACK of the SPS-PDSCH, and can be multiplexed by being concatenated after the HARQ-ACK bit of the DAI. Multiplexing can also be performed by being concatenated after the HARQ-ACK of the PDSCH.

[0075] 4b) In a case where the information on the power supply status is processed as one of UCI, HARQ-ACK, SR, or CSI, it can also be transmitted by being multiplexed with other UCI or UL-SCH. In a case where the information on the power supply status is processed as one of HARQ-ACK, SR, or CSI, actions involved in multiplexing and priority ordering of UCI, HARQ-ACK, SR, or CSI can be applied.

[0076] In a case where the information on the power supply status is processed as one of CSI, priority ordering of the CSI with each other can be any one of 1) to 4) shown below. Hereinafter, the information on the power supply status is assumed to be WPT-CSI.

[0077] 1) CSI reporting of L1-RSRP is prioritized over other CSI reporting including WPT-CSI.

[0078] 2) CSI reporting of L1-RSRP and WPT-CSI is prioritized over other CSI reporting.

[0079] 3) CSI reporting of L1-RSRP is prioritized over CSI reporting of WPT-CSI. Also, CSI reporting of WPT-CSI is prioritized over other CSI reporting.

[0080] 4) CSI reporting of L1-RSRP is prioritized over other CSI reporting except for WPT-CSI. Also, other CSI reporting except for WPT-CSI is prioritized over CSI reporting of WPT-CSI.

[0081] In a case where the information on the power supply status is processed as UCI other than HARQ-ACK, SR, and CSI, priority ordering of the UCI with each other can be any one of 1) to 4) shown below. Hereinafter, the information on the power supply status is assumed to be WPT-UCI.

[0082] 1) The priority can be, in descending order, HARQ-ACK, SR, CSI, WPT-UCI.

[0083] 2) The priority can be, in descending order, HARQ-ACK, WPT-UCI, SR, CSI.

[0084] 3) The priority can be, in descending order, HARQ-ACK, SR, WPT-UCI, CSI.

[0085] In a case where the information related to the power supply status is handled as UCI other than HARQ-ACK, SR, and CSI, channel coding, rate matching, mapping, and puncturing can be performed together with at least a part of HARQ-ACK, SR, and CSI. Further, in a case where the information related to the power supply status is handled as UCI other than HARQ-ACK, SR, and CSI, channel coding, rate matching, mapping, and puncturing can also be performed independently of HARQ-ACK, SR, and CSI.

[0086] 4c) In a case where the information related to the power supply status is contained in the UL-SCH and transmitted, it can be transmitted by any one of a MAC-CE, a MAC subheader, and a MAC-SDU (Service data unit). The priority order of data from a UL-CCCH (Common Control Channel), data from a logical channel other than data from the UL-CCCH, and a MAC-CE can be arbitrary. For example, the priority of the information related to the power supply status can be lower than the priority of data from the UL-CCCH. For example, the priority can also be lower than data from a logical channel other than data from the UL-CCCH.

[0087] By the above-described actions, the information related to the power supply status can be efficiently reported together with other report information.

[0088] By the above-described embodiments, the terminal 20 can report feedback information related to wireless power supply to the base station 10, and efficiently receive wireless power supply through control based on the feedback information.

[0089] That is, in a wireless communication system, feedback information related to wireless power supply can be reported.

For example, a functional block (structural unit) that functions to transmit is referred to as a transmitting unit or a transmitter. In general, as described above, the implementation method is not particularly limited.

[0105] For example, the base station 10, the terminal 20, and the like in one embodiment of the present disclosure can also function as a computer that performs processing of the wireless communication method of the present disclosure.

In this case, it can also be configured such that the terminal 20 has the functions of the base station 10 described above. In addition, the expressions such as "uplink" and "downlink" can also be replaced with expressions corresponding to inter-terminal communication (for example, "side"). For example, the uplink channel, the downlink channel, and the like can also be replaced with a side channel.

[0159] Likewise, the user terminal in the present disclosure can also be replaced with a base station. In this case, it can also be configured such that the base station has the functions of the user terminal described above.

In addition, "determining" or "deciding" can be replaced by "assuming", "expecting", "considering", or the like.

[0161] The terms "connected" and "coupled" or all modifications thereof mean all possible direct or indirect connections or couplings between the elements, which can include the existence of one or more intermediate elements between two elements "connected" or "coupled" to each other. The coupling or connection between the elements can be a physical or logical coupling or connection, or a combination thereof. For example, "access" can be replaced by "connection".

[0162] The reference signal can be simply referred to as RS (Reference Signal), and can be referred to as a pilot (Pilot) depending on the applied standard.

[0163] The expression "based on" as used in the present disclosure is not intended to mean "only based on" unless specifically stated otherwise. In other words, the expression "based on" means both "only based on" and "at least based on".

[0164] Any reference to elements using the expressions "1st", "2nd", and the like used in the present disclosure does not necessarily limit the number or order of the elements. These expressions can be used in the present disclosure as a convenient method of distinguishing between two or more elements. Accordingly, a reference to a 1st element and a 2nd element does not mean that only two elements are possible or that in any way the 1st element must precede the 2nd element in any way.

[0165] The expression "unit" in the structure of each of the above-described apparatuses can be replaced with the expression "part", "circuit", "device", or the like.

[0166] When the expressions "include", "including", and variations thereof are used in the present disclosure, these expressions mean the same as the expression "comprising". Also, the expression "or" used in the present disclosure does not mean the exclusive or.

[0167] 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 referred to as a subframe. A subframe can be composed of one or more slots in the time domain. A subframe can also be a fixed length of time (e.g., 1 ms) independent of numerology.

[0168] A numerology can be a communication parameter applied to at least one of transmission and reception of a certain signal or channel. The numerology can indicate at least one of, for example, a subcarrier spacing (SCS), a bandwidth, a symbol length, a cyclic prefix length, a transmission time interval (TTI), a number of symbols per TTI, a radio frame structure, a specific filtering process performed by a transceiver in the frequency domain, a specific windowing process performed by a transceiver in the time domain, and the like.

[0169] A slot can be constituted by one or a plurality of symbols (OFDM (Orthogonal Frequency Division Multiplexing) symbols, SC-FDMA (Single Carrier Frequency Division Multiple Access) symbols, and the like) in the time domain. A slot can be a time unit based on a numerology.

[0170] A slot can include a plurality of mini-slots. Each mini-slot can be constituted by one or a plurality of symbols in the time domain. Further, a mini-slot can also be referred to as a sub-slot. A mini-slot can be constituted by a smaller number of symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a mini-slot can be referred to as PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot can be referred to as PDSCH (or PUSCH) mapping type B.

[0171] A radio frame, a subframe, a slot, a mini-slot, and a symbol each represent a time unit in transmission of a signal. A radio frame, a subframe, a slot, a mini-slot, and a symbol can each be referred to by other names.

[0172] For example, 1 subframe can be referred to as a transmission time interval (TTI), a plurality of consecutive subframes can also be referred to as a TTI, 1 slot or 1 mini-slot can also be referred to as a TTI. That is, at least one of a subframe and a TTI can be a subframe (1 ms) in the existing LTE, can be a period shorter than 1 ms (for example, 1 to 13 symbols), or can be a period longer than 1 ms. In addition, a unit representing a TTI can not be referred to as a subframe, but can be referred to as a slot, a mini-slot, or the like.

[0173] Here, a TTI, for example, refers to a minimum time unit of scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling in which a radio resource (a frequency bandwidth, a transmission power, and the like, which can be used in each terminal 20) is allocated to each terminal 20 in units of a TTI. In addition, the definition of a TTI is not limited thereto.

[0174] A TTI can be a transmission time unit of a data packet (a transport block) after channel coding, a code block, a codeword, or the like, or can be a processing unit of scheduling, link adaptation, or the like. In addition, when a TTI is given, a time interval (for example, a number of symbols) in which a transport block, a code block, a codeword, or the like is actually mapped can be shorter than the TTI.

[0175] In addition, in a case where 1 slot or 1 mini-slot is referred to as a TTI, one or more TTIs (i.e., one or more slots or one or more mini-slots) can be a minimum time unit of scheduling. Further, the number of slots (mini-slots) constituting the minimum time unit of scheduling can be controlled.

[0176] A TTI having a time length of 1 ms is also referred to as a normal TTI (TTI in LTE Rel. 8-12), a normal TTI (normal subframe), a long TTI, a normal subframe, a normal subframe (normal subframe), a long (long) subframe, a slot, or the like. A TTI shorter than the normal TTI can also be referred to as a shortened TTI, a short TTI (short TTI), a partial TTI (partial or fractional TTI), a shortened subframe, a short (short) subframe, a mini-slot, a sub-slot, a slot, or the like.

[0177] In addition, for a long TTI (long TTI) (for example, a normal TTI, a subframe, or the like), it can be understood as a TTI having a time length exceeding 1 ms, and for a short TTI (short TTI) (for example, a shortened TTI, or the like), it can be understood as a TTI having a TTI length less than that of the long TTI (long TTI) and a TTI length of 1 ms or more.

[0178] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and in the frequency domain, can include one or more contiguous subcarriers. The number of subcarriers included in the RB can be the same regardless of the numerology, for example, can be 12. The number of subcarriers included in the RB can also be determined according to the numerology.

[0179] In addition, the time domain of the RB can include one or more symbols, and can be the length of 1 slot, 1 mini-slot, 1 subframe, or 1 TTI. One TTI, one subframe, or the like can each be constituted by one or more resource blocks.

[0180] In addition, one or more RBs can also be referred to as a physical resource block (PRB), a subcarrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, or the like.

[0181] In addition, a resource block can be constituted by one or more resource elements (REs). For example, 1 RE can be a wireless resource area of 1 subcarrier and 1 symbol.

[0182] 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.

[0183] 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.

[0184] At least one of the configured BWPs can be active, and it is not assumed that the UE will transmit or receive predetermined signals / channels outside of an active BWP. Furthermore, the terms "cell," "carrier," etc., used in this disclosure can be replaced with "BWP."

[0185] 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, and the number of symbols in a TTI, symbol length, and cyclic prefix (CP) length can be varied in many ways.

[0186] 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 also includes cases where the noun following these articles is in a plural form.

[0187] In this disclosure, the phrase "A and B are different" can mean "A and B are not the same." Additionally, 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."

[0188] 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 is not limited to explicit notification (e.g., a "Yes X" notification) but can also be implicit notification (e.g., not notifying the predetermined information).

[0189] The present disclosure has been described in detail above, but it should be clear to a person skilled in the art that the present disclosure is not limited to the embodiments described in the present disclosure. The present disclosure can be implemented in modified and changed forms without departing from the spirit and scope of the present disclosure defined by the claims. Therefore, the purpose of the present disclosure is to illustrate, and the present disclosure is not intended to have any limiting meaning.
