[0022] Hereinafter, an embodiment of the present application will be described with reference to the accompanying drawings. Note that the embodiment described below is merely an example, and the application of the embodiment of the present application is not limited to the following embodiment.

[0023] The wireless communication system of the embodiment of the present application can appropriately use existing technology when operating. The existing technology is, for example, existing LTE, but is not limited to existing LTE. Furthermore, unless otherwise specified, the term "LTE" used in this specification has a broad meaning that includes LTE-Advanced and modes after LTE-Advanced (e.g., NR).

[0024] Furthermore, 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, which are used in the existing LTE, are used. This is for ease of explanation, and the same signals, functions, and the like can be referred to by other names. Furthermore, the above terms in NR correspond to NR-SS, NR-PSS, NR-SSS, NR-PBCH, NR-PRACH, and the like. However, even in NR, the signals used can not necessarily be indicated by "NR-".

[0025] Furthermore, in the embodiments of the present application, the duplexing method can be a TDD (Time Division Duplex) method, an FDD (Frequency Division Duplex) method, or another method (for example, a flexible duplex method).

[0026] Furthermore, in the embodiments of the present application, the "configure" of the radio parameters and the like can be pre-configure a predetermined value, or can be configure radio parameters notified from the base station 10 or the terminal 20.

[0027] Figure 1 is a diagram illustrating an example of the structure of a wireless communication system in the embodiments of the present application. As shown in Figure 1 the wireless communication system in the embodiments of the present application includes the base station 10 and the terminal 20. Figure 1 One base station 10 and one terminal 20 are shown in each of the drawings, but this is merely an example, and a plurality of each can be provided.

[0028] The base station 10 is a communication device that provides one or more cells and performs wireless communication with the terminal 20. A physical resource of a wireless signal is defined by a time domain and a frequency domain, the time domain can be defined by a number of OFDM (Orthogonal Frequency Division Multiplexing) symbols, and the frequency domain can be defined by a number of subcarriers or a 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 by, for example, an NR-PBCH, and is also referred to as broadcast information. The synchronization signal and the system information can be referred to as an SSB (SS / PBCH block). As shown in Figure 1 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). Both the base station 10 and the terminal 20 are capable of performing beamforming for transmission and reception of signals. In addition, both the base station 10 and the terminal 20 are capable of applying MIMO (Multiple Input Multiple Output) based communication to the DL or the UL. Furthermore, both the base station 10 and the terminal 20 are capable of performing communication via a secondary cell (SCell) and a primary cell (PCell) based on CA (Carrier Aggregation). In addition, the terminal 20 can perform communication via a primary cell of the base station 10 and a primary secondary cell group cell (PSCell) of another base station 10 based on DC (Dual Connectivity).

[0029] 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 in Figure 1 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 signal.

[0030] Figure 2 is a diagram illustrating an example of a frequency range in an embodiment of the present application. In the NR specification of 3GPP Release 15 and Release 16, for example, a case where a frequency band of 52.6 GHz or more is used is studied. In addition, as shown inFigure 2 As shown, the currently prescribed FR (Frequency range) 1 is a frequency band of 410 MHz to 7.125 GHz, the SCS (Subcarrier spacing) is 15, 30, or 60 kHz, and the bandwidth is 5 MHz to 100 MHz. The FR2 is a frequency band of 24.25 GHz to 52.6 GHz, the SCS uses 60, 120, or 240 kHz, and the bandwidth is 50 MHz to 400 MHz. For example, it is conceivable that a newly prescribed frequency band is 52.6 GHz to 114.25 GHz.

[0031] The peak transmission power is generally limited by law. Here, for example, according to a certain regulation in the range of 57 to 71 GHz, the limit related to EIRP (equivalent isotropically radiated power) is as follows.

[0032] 1) Maximum average EIRP 40 dBm

[0033] 2) Maximum peak EIRP 43 dBm

[0034] 3) In the case where the emission-BW is less than 100 MHz, the maximum peak conducted output power 500 mW x emission-BW / 100 MHz

[0035] 4) In the case where the emission-BW is 100 MHz or more, the maximum peak conducted output power 500 mW

[0036] Among the several PUCCH formats in the past, as shown in Table 1, there is a configuration in which a single resource block (RB) is allocated. For example, it corresponds to a case where the number of resource blocks is set to 1 in PUCCH format 0 / 1 / 4, PUCCH format 2 / 3.

[0037] Table 1

[0038] Format PUCCH Format 0 PUCCH Format 1 PUCCH Format 2 PUCCH Format 3 PUCC Format 4 RB Size 1 RB 1 RB 1 - 16 RBs 1 - 16 RBs 1 RB

[0039] As described above, there is a case where the bandwidth of one resource block allocated to the PUCCH format is not a sufficient length required to satisfy the maximum PSD (Power spectrum density) limit and to reach the maximum allowable EIRP in the unlicensed band of 60 GHz, for example, as prescribed above.

[0040] Therefore, a method of allocating a plurality of resource blocks to a PUCCH is studied. For example, in a case where a bandwidth exceeding 3.98 MHz needs to be allocated to a PUCCH resource in order to achieve the maximum allowable EIRP, in a 480 kHz or 960 kHz SCS, in one resource block, the bandwidth is 5.76 MHz or 11.52 MHz, which has a sufficient length, respectively.

[0041] On the other hand, in a 120 kHz or 240 kHz SCS, in order to be set to a bandwidth exceeding 3.98 MHz, in one resource block, the length is insufficient, and in order to achieve the maximum allowable EIRP, at least three resource blocks or two resource blocks are needed, respectively.

[0042] As described above, in order to achieve the maximum allowable EIRP, the PUCCH in the unlicensed band needs to be strengthened.

[0043] Thus, in order to satisfy the regulations of each country and achieve the maximum allowable EIRP, and strengthen the coverage of the PUCCH, 1) and 2) shown below are proposed.

[0044] 1) The number of resource blocks can be set for each PUCCH format.

[0045] 2) The SCS is applied so that one resource block allocated to the PUCCH satisfies the required bandwidth.

[0046] Figure 3 is a flowchart for explaining an example (1) of a PUCCH in an embodiment of the present application. In step S11, the terminal 20 is allocated the number of resource blocks that achieves the required bandwidth for the PUCCH. For the number X of resource blocks allocated to the PUCCH, a setting can be made with a change, for example, it can be provisioned in advance by a specification, or it can be set by RRC (Radio Resource Control) setting. That is, the base station 10 can set the number X of resource blocks allocated to the PUCCH to the terminal 20 via RRC signaling. In addition, the resource block is an example of a unit in the frequency domain, and for example, other units in the frequency domain such as the number of subcarriers can be used.

[0047] The number X of resource blocks allocated to the PUCCH is a value that satisfies the required bandwidth. In addition, the number X of resource blocks allocated to the PUCCH can be decided in accordance with the SCS. For example, three resource blocks can be set to the PUCCH in the case where the SCS is 120 kHz, two resource blocks can be set to the PUCCH in the case where the SCS is 240 kHz, one resource block can be set to the PUCCH in the case where the SCS is 480 kHz, and one resource block can be set to the PUCCH in the case where the SCS is 960 kHz, respectively. In addition, the number X of resource blocks is an example of a representation of the size in the frequency domain, and for example, another expression representing the size in the frequency domain, such as the number Y of subcarriers, can also be used.

[0048] In addition, the number X of resource blocks allocated to the PUCCH can be decided in accordance with the TCI (Transmission Configuration Indicator) or the RRC information element "PUCCH-SpatialRelationInfo". The TCI and the PUCCH-SpatialRelationInfo are parameters related to spatial multiplexing, and for example, the setting of a beam applied to the PUCCH is performed.

[0049] For example, one resource block can be set to the PUCCH in the case where the TCI state ID is 0, two resource blocks can be set to the PUCCH in the case where the TCI state ID is 1, and three resource blocks can be set to the PUCCH in the case where the TCI state ID is 2, respectively.

[0050] For example, in the case where the PUCCH-SpatialRelationInfo is activated by a higher layer parameter, the number of resource blocks allocated to the PUCCH can be set in accordance with the PUCCH-SpatialRelationInfo. On the other hand, in the case where the PUCCH-SpatialRelationInfo is not provided from the higher layer, the number of resource blocks allocated to the PUCCH can be set in accordance with the TCI state ID.

[0051] The number of values that can be taken by the number X of resource blocks allocated to the PUCCH can be predetermined by a specification, can be set by RRC setting, or can be notified by DCI (Downlink Control Information).

[0052] As described above, the number X of resource blocks can be decided in accordance with the value of the RRC information element, the DCI, or the parameter related to spatial multiplexing.

[0053] For the resource configuration of the PUCCH, for example, a contiguous resource can be allocated, a non-contiguous resource can be allocated, or allocation can be made by a bitmap based on a resource block group (RBG). The bitmap based on the RBG can be the same as the frequency-domain resource allocation type 0 (frequency-domain resource allocation type 0) of the LTE-A.

[0054]

[0055] In the next step S12, the terminal 20 maps the PUCCH to the physical resource. The terminal 20 can map the PUCCH to the physical resource as described in 1) to 5) below.

[0056] 1) The transmission is mapped to each of the plurality of resource blocks allocated repeatedly. For example, in a case where the number of the resource blocks allocated is X, an interlace value can be set to 0 and an interlace number can be set to X.

[0057] 2) In a case of the PUCCH format 0 and the PUCCH format 1, a new sequence is used. For example, as the resource allocated to the frequency domain is increased from the PUCCH format 0 and the PUCCH format 1 of the past, a sequence having a longer sequence length than the sequence used in the PUCCH format 0 and the PUCCH format 1 of the past can be used.

[0058] 3) In a case of the PUCCH format 2 and the PUCCH format 3, the code rate r, the modulation order Q m , the number of PUCCH symbols N symb-UCI PUCCH , and the number of subcarriers Nsc ，ctrl RB of each resource block of each PUCCH format can be adjusted. Any one or more of these parameters can be adjusted. In addition, in a case where the resource of the frequency domain cannot be adjusted by adjusting these parameters, an exceptional process can be generated. For example, as the resource allocated to the frequency domain is increased from the PUCCH format 2 and the PUCCH format 3 of the past, the code rate or the modulation order can be decreased.

[0059] 4) In a case of the PUCCH format 2 and the PUCCH format 3, UCI bits are added to the PUCCH format or a reference signal is added to the physical resource. For example, as the resource allocated to the frequency domain is increased from the PUCCH format 2 and the PUCCH format 3 of the past, the insertion density of the reference signal can be increased, or bits for padding can be added.

[0060] ​5) Multiplexing by TDD-OCC (Time Division Duplex Orthogonal Cover Code). For example, multiplexing with other users' PUCCHs can be performed. In addition, multiplexing by FDD-OCC (Frequency Division Duplex Orthogonal Cover Code) can be performed.

[0061] The options of 1) to 5) above can be applied independently for each PUCCH format. In addition, the options of 1) to 5) above can be applied in combination for each PUCCH format.

[0062] In addition, the terminal 20 can report to the base station 10 whether or not support for the resource block allocation for the PUCCH described above is supported in accordance with the UE capability. In addition, the proposal 1) above and the proposal 2) below or each option can be combined. In addition, in a case where a specific higher layer parameter is set, the proposal above can be supported. For example, in a case where the higher layer parameter is not provided, the number of resource blocks allocated to the PUCCH can be set in accordance with the current specification, can be set in accordance with a new specification targeting unlicensed bands exceeding 52.6 GHz, or can be notified via DCI. In addition, the UE capability can be expressed as UE capability information, which is information indicating the capability of the terminal 20 notified from the terminal 20 to the base station 10.

[0063] Figure 4 is a flowchart for explaining an example (2) of the PUCCH in the embodiment of the present application. In step S21, the terminal 20 applies the SCS that reaches the required bandwidth in one resource block to the PUCCH. For example, the SCS applied to the PUCCH can be different from the SCS applied to other channels. In addition, for example, the terminal 20 can apply the SCS that satisfies the required bandwidth to reach the maximum allowable EIRP in one resource block to the PUCCH and use the PUCCH format specified in the current specification. For example, for the SCS of 480 kHz or 960 kHz, in order to satisfy the required bandwidth in one resource block, either one of the SCS of 480 kHz and 960 kHz can be applied to the PUCCH.

[0064] Further, a plurality of SCSs can be set as candidates to be applied to the PUCCH. The SCSs can be selected in accordance with a TCI or an RRC information element "PUCCH-SpatialRelationInfo". For example, 120 kHz SCS can be applied to the PUCCH in the case of a TCI state ID of 0, 240 kHz SCS can be applied to the PUCCH in the case of a TCI state ID of 1, and 480 kHz SCS can be applied to the PUCCH in the case of a TCI state ID of 2.

[0065] For the one or more SCSs to be applied to the PUCCH, the SCSs can be set by a specification, by RRC setting, or by DCI notification. For example, the plurality of SCSs can be set in accordance with the RRC information element "PUCCH-SpatialRelationInfo", and which SCS to use can be notified by DCI or can be determined by the specification. In addition, the terminal 20 can report to the base station 10 whether or not the SCS setting method for the PUCCH described above is supported in accordance with the UE capability.

[0066] In addition, in the case where a specific higher layer parameter is set, the proposal described above can be supported. For example, in the case where the higher layer parameter is not provided, the SCS to be applied to the PUCCH can be set in accordance with the current specification, for example, can be set in accordance with a new specification for unlicensed bands exceeding 52.6 GHz, or can be notified via DCI.

[0067] In addition, the step S22 can be executed similarly to the step S12 shown in Figure 3

[0068] In addition, in the case where the SCSs applied to the PUCCH and the other channel are different, the terminal 20 can assume a delay in switching the SCSs. In addition, the terminal 20 can report to the base station 10 whether or not the SCS setting method for the PUCCH described above is supported in accordance with the UE capability.

[0069] In addition, in the case where a specific higher layer parameter is set, the proposal described above can be supported. For example, in the case where the higher layer parameter is not provided, the number of candidates of the SCS to be applied to the PUCCH can be set in accordance with the current specification, for example, can be set in accordance with a new specification for unlicensed bands exceeding 52.6 GHz, or can be notified via DCI.

[0070] With the embodiments described above, the base station 10 and the terminal 20 can set the bandwidth of the PUCCH that satisfies the regulation related to the peak EIRP by controlling the number of resource blocks or the SCS.

[0071] ​That is, in the wireless communication system, resource allocation that is adapted to a frequency band can be performed.

Further, the method of realizing each functional block is not particularly limited. That is, each functional block can be realized using one device that is physically or logically integrated, or two or more devices that are physically or logically separated can be directly or indirectly (for example, using wired, wireless, or the like) connected and realized using the plurality of devices. Each functional block can also be realized by combining software with the above-described one device or the above-described plurality of devices.

For example, a functional block (structural unit) that causes transmission to function is referred to as a transmitting unit or a transmitter. In any case, as described above, the implementation method is not particularly limited.

[0087] 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. Figure 7 is a diagram illustrating an example of a hardware structure of the base station 10 and the terminal 20 according to one embodiment of the present disclosure. The base station 10 and the terminal 20 described above can also be configured as a computer device that physically includes the processor 1001, the storage 1002, the auxiliary storage 1003, the communication device 1004, the input device 1005, the output device 1006, the bus 1007, and the like.

The hardware structure of the base station 10 and the terminal 20 can be configured to include one or a plurality of each of the devices illustrated in the drawings, or can be configured not to include a part of the devices.

[0089] Each function in the base station 10 and the terminal 20 is implemented by reading predetermined software (program) into the hardware such as the processor 1001 and the storage 1002, so that the processor 1001 performs arithmetic operation and controls at least one of communication of the communication device 1004 or reading and writing of data in the storage 1002 and the auxiliary storage 1003.

The processor 1001 can also be configured by a central processing device (CPU: Central Processing Unit) including an interface with a peripheral device, a control device, an arithmetic device, a register, and the like. For example, the control unit 140, the control unit 240, and the like described above can also be implemented by the processor 1001.

[0091] Further, the processor 1001 reads out programs (program codes), software modules, or data, etc., from the storage device 1003 and the communication device 1004 at least one of them to the storage device 1002 and executes various processes according to the programs. As the program, a program that causes a computer to execute at least a part of the operations described in the above-described embodiments is used. For example, Figure 5 The control section 140 of the base station 10 illustrated can also be realized by a control program stored in the storage device 1002 and operated by the processor 1001. Further, for example, Figure 6 The control section 240 of the terminal 20 illustrated can also be realized by a control program stored in the storage device 1002 and operated by the processor 1001. As for the above-described various processes, although it is described that the above-described various processes are executed by one processor 1001, the above-described various processes can also be executed by two or more processors 1001 simultaneously or sequentially. The processor 1001 can also be mounted by one or more chips. In addition, the program can also be transmitted from a network via a telecommunication line.

[0109] The above describes the embodiments of the present application, but the disclosed application is not limited to such embodiments, and those of ordinary skill in the art will understand various modifications, changes, alternatives, substitutions, and the like. Specific numerical examples are used for facilitating understanding of the application, but as long as not specifically indicated, these numerical examples are only examples, and any appropriate value can be used. The division of items in the above description is not essential to the present application, and matters described in two or more items can be used in combination as needed, or matters described in one item can be applied to matters described in another item (as long as not contradictory). The boundary of a functional block or a processing block in a functional block diagram does not necessarily correspond to the boundary of a physical component. The actions of multiple functional blocks can be physically performed by one component, or the actions of one functional block can be physically performed by multiple components. As for the processing procedures described in the embodiments, the order of the processing can be changed without contradiction. For facilitating the description of the processing, the base station 10 and the terminal 20 are described using functional block diagrams, but such devices can also be implemented in hardware, in software, or in a combination thereof.

[0110] Further, the notification of the information is not limited to the form / implementation described in the present disclosure, and can be performed using other methods. For example, the notification of the information can be implemented by 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 a combination thereof. Further, the RRC signaling can also be referred to as an RRC message, and for example, can be an RRC connection setup message, an RRC connection reconfiguration message, or the like.

[0112] For the processes, procedures, timing, flow, and the like of each form / embodiment described in this specification, the order can be changed without contradiction. For example, for the method described in this disclosure, the elements of various steps are prompted using the order of the examples, but are not limited to the specific order prompted.

[0113] In this specification, specific actions performed by the base station 10 are sometimes performed by an upper node thereof according to the situation. In a network constituted by one or a plurality of network nodes having the base station 10, it is obvious that various actions performed for communication with the terminal 20 can be performed by at least one of the base station 10 and other network nodes (for example, consider MME or S-GW, etc., but not limited to these) other than the base station 10. In the above, a case where the other network node other than the base station 10 is one is exemplified, but the other network node can also be a combination of a plurality of other network nodes (for example, MME and S-GW).

[0114] Information or signals and the like described in this disclosure can be output from a higher layer (or lower layer) to a lower layer (or higher layer). It can also be input or output via a plurality of network nodes.

[0115] Information and the like input or output can be saved in a specific location (for example, a memory), and can be managed using a management table. The information and the like input or output can be rewritten, updated, or appended. The information and the like output can also be deleted. The information and the like input can also be transmitted to other devices.

[0116] The determination in this disclosure can be performed by a value (0 or 1) represented by 1 bit, by a Boolean value (true or false), or by comparison of numerical values (for example, comparison with a predetermined value).

[0117] For software, regardless of being called software, firmware, middleware, microcode, hardware description language, or by other names, it should be broadly interpreted as referring to commands, command 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 the like.

[0118] Moreover, software, commands, information, and so on can be transmitted via transmission media. For example, if the software is transmitted from a webpage, a server, or other remote source using at least one of wired technology (e.g., coaxial cables, fiber optic cables, twisted pair, digital subscriber line (DSL), or the like) and / or wireless technology (e.g., infrared, microwave, or the like), at least a portion of the transmission media is within the definition of transmission media.

[0119] Information, signals, and so on in the present disclosure can be represented using any of a variety of different technologies and techniques. For example, data, commands, instructions, information, signals, bits, symbols, chips, and so on that can be referenced throughout the above description can be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.

[0120] Further, terms described in the present disclosure and terms necessary for understanding the present disclosure can be replaced with terms having the same or similar meanings. For example, at least one of a channel and a symbol can also be a signal (signaling). Further, a signal can also be a message. In addition, a component carrier (CC) can be referred to as a carrier frequency, a cell, a frequency carrier, or the like.

[0121] The terms "system" and "network" and so on used in the present disclosure can be used interchangeably.

[0122] Further, information, parameters, and so on described in the present disclosure can be represented using absolute values, can be represented using relative values from predetermined values, and can be represented using corresponding other information. For example, a radio resource can also be indicated by an index.

[0123] The names used for the above-described parameters are non-limiting in any respect. Further, the mathematical expressions and so on using these parameters are sometimes different from what is explicitly shown in the present disclosure. A variety of channels (e.g., PUCCH, PDCCH, and so on) and information elements can be identified by appropriate names, and thus a variety of names assigned to the variety of channels and information elements are non-limiting in any respect.

[0124] In the present disclosure, the terms "base station (BS)," "radio 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," "component carrier," and the like can be used interchangeably. The base station is also called a macro cell, a small cell, a femto cell, a pico cell, and the like at times.

[0125] A base station can accommodate one or plural (for example, three) cells. In a case where a base station accommodates plural cells, the coverage area of the base station as a whole can be divided into plural smaller areas, and each of the smaller areas can be provided with a communication service by a base station subsystem (for example, a small base station for indoor use (RRH: Remote Radio Head)). The term "cell" or "sector" refers to a part or the whole of the coverage area of at least one of the base station and the base station subsystem that provides a communication service in the coverage range.

[0126] In the present disclosure, the terms "mobile station (MS)," "user terminal," "user equipment (UE)," "terminal," and the like can be used interchangeably.

[0127] For a mobile station, the skilled person also calls it at times with 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, handset, user agent, mobile client, client, or some other suitable terminology.

[0128] At least one of the base station and the mobile station can also be referred to as a transmission device, a reception device, a communication device, or the like. In addition, at least one of the base station and the mobile station can be a device mounted on a mobile body, the mobile body itself, or the like. The mobile body can be a vehicle (for example, an automobile, an airplane, or the like), can be a mobile body that moves in an unmanned manner (for example, a drone, a self-driving automobile, or the like), or can be a robot (manned or unmanned). In addition, at least one of the base station and the mobile station also includes a device that does not necessarily move when performing communication. For example, at least one of the base station and the mobile station can be an IoT (Internet of Things) device such as a sensor.

[0129] Furthermore, the base station in the present disclosure can also be replaced with a user terminal. For example, regarding a structure in which communication between a base station and a user terminal is replaced with communication between a plurality of terminals 20 (for example, a structure also referred to as D2D (Device-to-Device), V2X (Vehicle-to-Everything), or the like), each form / embodiment of the present 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, the expressions "uplink" and "downlink" and the like 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.

[0130] Likewise, the user terminal in the present disclosure can also be replaced with a base station. In this case, the base station can also be configured to have the functions of the user terminal described above.

[0131] The terms "determining" and "deciding" as used in the present disclosure also include various actions sometimes. For example, "determining" and "deciding" can include cases where matters that have been judged, calculated, computed, processed, derived, investigated, searched (for example, searched in a table, a database, or other data structures), ascertained, and the like are regarded as "determined" and "decided". In addition, "determining" and "deciding" can include cases where matters that have been received (for example, received information), transmitted (for example, transmitted information), input, output, accessed (for example, accessed data in a memory), and the like are regarded as "determined" and "decided". Furthermore, "determining" and "deciding" can include cases where matters that have been resolved, selected, chosen, established, compared, and the like are regarded as "determined" and "decided". That is, "determining" and "deciding" can include cases where any action has been "determined" and "decided". In addition, "determining" and "deciding" can be replaced with "assuming", "expecting", and "considering".

[0132] The terms "connected" and "coupled" or all modifications of these terms used in the present disclosure are intended to mean all direct or indirect connections or couplings between two or more elements, and can include cases where one or more intervening elements exist between the two elements that are "connected" or "coupled" with each other. The coupling or connection between elements can be a physical coupling or connection, a logical coupling or connection, or a combination of these. For example, "connected" can be replaced with "accessed". In the present disclosure, for two elements, it can be considered that the two elements are "connected" or "coupled" with each other by using at least one of a wire, a cable, and a printed electric connection, and as some non-limiting and non-inclusive examples, by using electromagnetic energy such as electromagnetic energy having a wavelength in a radio frequency domain, a microwave region, and an optical (including both visible and non-visible) region.

[0133] A reference signal can be simply referred to as RS (Reference Signal), and can also be referred to as a pilot depending on the applied standard.

[0134] The expression "according to" as used in the present disclosure does not mean "only according to" unless explicitly stated otherwise. In other words, the expression "according to" means both "only according to" and "at least according to".

[0135] Any reference to elements using the expressions "first", "second", and the like used in the present disclosure does not necessarily limit the number and the order of the elements. These expressions are used in the present disclosure as a convenient method for distinguishing between two or more elements. Thus, a reference to first and second elements does not mean that there can be only two elements or that the first element must precede the second element in any manner.

[0136] The "unit" in each of the above-described device structures can be replaced with "section", "circuit", "device", or the like.

[0137] 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 means not only the exclusive or but also the inclusive or.

[0138] A radio frame can be composed of one or more slots in the time domain. One or more slots in the time domain can also be referred to as a subframe. A subframe can be composed of one or more slots in the time domain. The subframe can be a fixed length of time (e.g., 1 ms) regardless of numerology.

[0139] A numerology can also 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.

[0140] A slot can be configured with one or plural 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.

[0141] A slot can also include plural mini-slots. Each mini-slot can be configured with one or plural symbols in the time domain. In addition, a mini-slot can also be referred to as a sub-slot. A mini-slot can also be configured with a smaller number of symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a mini-slot can also be referred to as PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot can also be referred to as PDSCH (or PUSCH) mapping type B.

[0142] A radio frame, a subframe, a slot, a mini-slot, and a symbol each represent a time unit for transmitting a signal. A radio frame, a subframe, a slot, a mini-slot, and a symbol can also be referred to by other names respectively corresponding thereto.

[0143] For example, 1 subframe can also be referred to as a transmission time interval (TTI), plural 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, 1-13 symbols), or can be a period longer than 1 ms. Furthermore, a unit representing a TTI can not be a subframe, but can be referred to as a slot, a mini-slot, or the like.

[0144] 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 domain width, 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. Furthermore, the definition of a TTI is not limited thereto.

[0145] 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. Furthermore, when a TTI is given, a time interval (for example, a number of symbols) in which an actual transport block, code block, codeword, or the like is mapped can be shorter than the TTI.

[0146] Further, 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 also constitute the minimum time unit of scheduling. In addition, the number of slots (the number of mini-slots) constituting the minimum time unit of the scheduling can also be controlled.

[0147] A TTI having a time length of 1 ms can be referred to as a normal TTI (a TTI in LTE Rel. 8-12), a usual TTI, a long TTI, a normal subframe, a usual subframe, a long subframe, a slot, etc. A TTI shorter than the usual TTI can be referred to as a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a mini-slot, a sub-slot, a slot, etc.

[0148] Further, a long TTI (e.g., a normal TTI, a subframe, etc.) can be replaced with a TTI having a time length longer than 1 ms, and a short TTI (e.g., a shortened TTI, etc.) can be replaced with a TTI having a TTI length shorter than that of a long TTI and a TTI length of 1 ms or more.

[0149] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and in the frequency domain, can also include one or more contiguous subcarriers. The number of subcarriers included in an RB can be the same regardless of numerologies, and for example, can be 12. The number of subcarriers included in an RB can be determined based on numerologies.

[0150] Further, the time domain of an RB can include one or more symbols, and can also be the length of 1 slot, 1 mini-slot, 1 subframe, or 1 TTI. 1 TTI, 1 subframe, etc. can also be constituted by one or more resource blocks, respectively.

[0151] Further, 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, etc.

[0152] Further, a resource block can also be constituted by one or more resource elements (REs). For example, 1 RE can also be a wireless resource area of 1 subcarrier and 1 symbol.

[0153] A bandwidth part (BWP: Bandwidth Part) (may also be referred to as a partial bandwidth, etc.) is a subset of contiguous common resource blocks (RBs) in a certain carrier, and can also indicate a certain subset of common RBs with respect to a certain numerology. Here, the common RBs can also be determined by the index of the RBs with respect to a common reference point of the carrier. The PRBs can also be defined by a certain BWP and numbered within the BWP.

[0154] The BWP can also include a BWP for UL (UL BWP) and a BWP for DL (DL BWP). For the UE, one or more BWPs can also be configured within one carrier.

[0155] At least one of the configured BWPs can also be activated, and the UE can not be assumed to transmit / receive a predetermined signal / channel outside the activated BWP. In addition, "cell", "carrier", etc. in the present disclosure can also be replaced with "BWP".

[0156] The above-described structures of the radio frame, the subframe, the slot, the mini-slot, the symbol, etc. are merely examples. For example, the number of subframes included in the radio frame, the number of slots in each subframe or radio frame, the number of mini-slots included in the slot, the number of symbols and RBs included in the slot or mini-slot, the number of subcarriers included in the RB, the number of symbols in the TTI, the symbol length, the cyclic prefix (CP) length, etc. can be variously changed.

[0157] In the present disclosure, for example, in the case where an article is added by a translation of a, an, and the in English, the present disclosure also includes a case where the article after the addition is plural.

[0158] In the present disclosure, the expression "A and B are different" can also mean that "A and B are different from each other". In addition, the expression can also mean that "A and B are different from C, respectively". The expressions "separate", "combine", etc. can also be interpreted as "different" in the same manner.

[0159] Each of the modes / embodiments described in the present disclosure can be used alone, in combination, or switched according to execution. In addition, the notification of the predetermined information is not limited to being performed explicitly (for example, notification of "X"), but can also be performed implicitly (for example, without performing the notification of the predetermined information).

[0160] In addition, the PUCCH in the present disclosure is an example of a physical uplink control channel. The TCI state ID or PUCCH-SpatialRelationInfo is an example of a parameter related to spatial multiplexing.

[0161] The present disclosure has been described in detail above, but it should be understood that the present disclosure is not limited to the embodiments described in the present disclosure. The present disclosure can be implemented in various modified and changed forms without departing from the spirit and scope of the present disclosure defined by the claims. Therefore, the present disclosure is intended to be illustrative, not limiting.
