Description

[Technical Field]

[0001] The present invention relates to a terminal, a base station, and a communication method in a wireless communication system. [Background technology]

[0002] For NR (New Radio) (also known as "5G"), the successor system to LTE (Long Term Evolution), technologies that satisfy requirements such as a large-capacity system, high-speed data transmission speed, low latency, simultaneous connection of a large number of terminals, low cost, and low power consumption are being considered (for example, Non-Patent Document 1).

[0003] NR Release 17 is considering the use of higher frequency bands than previous releases (e.g., Non-Patent Document 2). For example, in the frequency band from 52.6 GHz to 71 GHz, applicable numerology including subcarrier spacing and channel bandwidth, physical layer design, and expected interference in actual wireless communications are being considered.

[0004] In addition, in NR, semi-persistent scheduling (SPS) to reduce downlink overhead is being studied, continuing from LTE. Furthermore, in NR, configured grant (CG) to reduce uplink latency is being studied. [Prior art documents] [Non-patent literature]

[0006] There is a problem that specifications for applying wireless communication systems to high frequency bands have not been defined. For example, for high frequency bands such as 52.6 GHz to 71 GHz, a multi-PDSCH scheduling function that schedules multiple PDSCHs in one DCI or a multi-PUSCH scheduling function that schedules multiple PUSCHs in one DCI is being considered. However, there is a problem that there has been insufficient consideration of the combined use of the multi-PDSCH scheduling function or the multi-PUSCH scheduling function with SPS or CG.

[0007] The present invention has been made in view of the above points, and has as its object to apply a wireless communication system to a high frequency band. [Means for solving the problem]

[0008] According to the disclosed technology, The first index specifies the parameters of the resource allocation in the time domain. Control information including , from the base station a receiving unit for receiving the signal; When resources are identified based on a plurality of second indexes corresponding to the first index, scheduling of a plurality of data is controlled based on the resources. A control unit and If the second index corresponding to the first index is one and an NDI (New Data Indicator) field included in the control information is set to "0", the control unit enables activation of scheduling of downlink data by semi-persistent scheduling or uplink data by a configuration grant in a resource identified based on the second index. A terminal is provided. [Effects of the Invention]

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the embodiment described below is an example, and the embodiment to which the present invention is applied is not limited to the following embodiment.

[0012] In operation of the wireless communication system according to the embodiment of the present invention, existing technologies may be used as appropriate. The existing technologies include, but are not limited to, existing NR or LTE. Furthermore, the term "LTE" used in this specification has a broad meaning including LTE-Advanced and systems subsequent to LTE-Advanced (e.g., NR) unless otherwise specified.

[0013] Furthermore, in the embodiments of the present invention described below, terms used in existing LTE, such as SS (Synchronization signal), PSS (Primary SS), SSS (Secondary SS), PBCH (Physical broadcast channel), PRACH (Physical random access channel), PDCCH (Physical Downlink Control Channel), PDSCH (Physical Downlink Shared Channel), PUCCH (Physical Uplink Control Channel), and PUSCH (Physical Uplink Shared Channel), are used. This is for convenience of description, and similar signals, functions, etc. may be referred to by other names. Furthermore, the above-mentioned terms in NR correspond to NR-SS, NR-PSS, NR-SSS, NR-PBCH, NR-PRACH, etc. However, even signals used in NR are not necessarily designated as "NR-".

[0014] Furthermore, in the embodiments of the present invention, the duplex method may be a TDD (Time Division Duplex) method, an FDD (Frequency Division Duplex) method, or other methods (for example, Flexible Duplex, etc.).

[0015] Furthermore, in the embodiments of the present invention, "configuring" radio parameters and the like may mean that predetermined values ​​are pre-configured, or that radio parameters notified from a base station or a terminal are set.

[0016] (System Configuration) FIG. 1 is a diagram illustrating a wireless communication system according to an embodiment of the present invention. As shown in Fig. 1, a wireless communication system according to an embodiment of the present invention includes a base station 10 and a terminal 20. Although Fig. 1 shows one base station 10 and one terminal 20, 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 a wireless signal are defined in the time domain and the frequency domain, and the time domain may be defined by the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols, and the frequency domain may be defined by the number of subcarriers or the number of resource blocks. Furthermore, a TTI (Transmission Time Interval) in the time domain may be a slot, or a TTI may be a subframe.

[0018] The base station 10 transmits a synchronization signal and system information to the terminal 20. The synchronization signal is, for example, NR-PSS and NR-SSS. The system information is transmitted, for example, via the NR-PBCH and is also referred to as broadcast information. The synchronization signal and system information may be referred to as an SSB (SS / PBCH block). As shown in FIG. 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). Both the base station 10 and the terminal 20 are capable of transmitting and receiving signals by performing beamforming. Furthermore, both the base station 10 and the terminal 20 are capable of applying MIMO (Multiple Input Multiple Output) communication to DL or UL. Furthermore, both the base station 10 and the terminal 20 may communicate via a secondary cell (SCell) and a primary cell (PCell) using Carrier Aggregation (CA). Furthermore, the terminal 20 may perform communication via a primary cell of the base station 10 and a primary secondary cell group cell (PSCell: Primary SCG Cell) of another base station 10 using DC (Dual Connectivity).

[0019] The terminal 20 is a communication device equipped with a wireless communication function, such as a smartphone, a mobile phone, a tablet, a wearable terminal, or an M2M (Machine-to-Machine) communication module. As shown in FIG. 1, the 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. The terminal 20 also receives various reference signals transmitted from the base station 10 and measures the propagation path quality based on the reception results of the reference signals. The terminal 20 may also be referred to as a UE, and the base station 10 may also be referred to as a gNB.

[0020] FIG. 2 is a diagram illustrating an example of a frequency range according to an embodiment of the present invention. In the NR specifications of 3GPP Release 15 and Release 16, operation of a frequency band of 52.6 GHz or higher is being considered. As shown in FIG. 2, the currently specified frequency range (FR) 1 is a frequency band from 410 MHz to 7.125 GHz, with a subcarrier spacing (SCS) of 15, 30, or 60 kHz and a bandwidth of 5 MHz to 100 MHz. FR2-1 is a frequency band from 24.25 GHz to 52.6 GHz, with an SCS of 60, 120, or 240 kHz and a bandwidth of 50 MHz to 400 MHz. Furthermore, FR2-2, a newly operated frequency band, is a frequency band from 52.6 GHz to 71 GHz.

[0021] In the newly operated frequency band FR2-2, up to 64 SSB beams may be supported in both licensed and unlicensed bands. In addition, the initial BWP (Bandwidth Part) may support 120 kHz SCS for SSB and 120 kHz SCS for initial access signals and channels.

[0022] In addition to the 120 kHz SCS, an SSB with a 480 kHz SCS may be supported. The SSB may be used to perform initial access supporting the CORESET (Control Resource Set) #0 / Type 0-PDCCH included in the MIB. However, the following restrictions may be imposed. For example, the entry number of the synchronization raster may be restricted. Furthermore, in the case of an SSB with a 480 kHz SCS, only the CORESET #0 / Type 0-PDCCH with a 480 kHz SCS may be supported. Furthermore, SSB-CORESET multiplexing pattern 1 (SS / PBCH block and CORESET multiplexing pattern 1) may be prioritized.

[0023] Unique identification of ANR (Automatic Neighbor Relation) and PCI (Physical Cell Identity) for detecting SSBs of 120 kHz SCS, 480 kHz SCS, and 960 kHz SCS may be supported. Also, CORESET#0 / Type0-PDCCH included in the MIB for SSBs of 120 kHz SCS, 480 kHz SCS, and 960 kHz SCS may be supported. Also, one CORESET#0 / Type0-PDCCH SCS may be supported per SSB SCS. For example, {SSB SCS, CORESET#0 / Type0-PDCCH SCS} may be supported as {120, 120}, {480, 480}, or {960, 960}.

[0024] Next, a multi-PDSCH scheduling function or a multi-PUSCH scheduling function that is being considered in NR Release 17 will be described.

[0025] In the case of a Time Domain Resource Assignment (TDRA) included in a DCI that can schedule multiple PDSCHs (or PUSCHs), a function is being considered to indicate PDSCHs (or PUSCHs) in consecutive or non-consecutive slots by setting {SLIV (Start and Length Indicator Value), mapping type, or scheduling offset K0 (or K2)} for each PDSCH (or PUSCH) included in each row of the TDRA table. The SLIV is a value that specifies the start position and length of a resource and is an example of a value that indicates resource scheduling.

[0026] Next, we will explain the activation and release (deactivation) of SPS considered in NR Release 17. The base station 10 can use DCI0_0, DCI0_1, or DCI0_2 to instruct the terminal 20 to activate or release a PUSCH configuration of Type 2CG.

[0027] When activating the type 2CG PUSCH, the base station 10 can indicate the time domain resource allocation for the type 2CG PUSCH to the terminal 20 by the TDRA field of the activation DCI.

[0028] Furthermore, when releasing a PUSCH of type 2 CG, the base station 10 can instruct the terminal 20 to release one or more type 2 CG configurations using a single DCI.

[0029] Similarly, the base station 10 can use DCI1_0, DCI1_1 or DCI1_2 to instruct the terminal 20 to activate or release the PDSCH configuration of the SPS.

[0030] When activating the PDSCH of the SPS, the base station 10 can indicate the time domain resource allocation of the PDSCH of the SPS to the terminal 20 by the TDRA field of the activation DCI.

[0031] Furthermore, when releasing the PDSCH of the SPS, the base station 10 can instruct the terminal 20 to release one or more SPS settings using a single DCI.

[0032] Next, a method for enabling or disabling SPS in DL and Type 2 CG in UL by PDCCH will be described.

[0033] The terminal 20 enables scheduling activation or scheduling release via the PDCCH for SPS allocation in DL or the PDCCH for type 2 CG in UL, if the following enabling conditions are met:

[0034] The conditions for activation are that all of the following are met: (a) The CRC of the corresponding DCI format is scrambled with the CS-RNTI. (b) The NDI (New Data Indicator) field included in the DCI format of a valid TB (Transport Block) is set to “0”. (c) If present, the DFI flag field of the DCI format is set to "0". (d) If the activation is for a scheduling activation and the "PDSCH-to-HARQ_feedback" timing indicator field in the DCI format is present, the "PDSCH-to-HARQ_feedback" timing indicator field does not provide an inapplicable value from "dl-DataToUL-ACK-r16".

[0035] 3 is a diagram for explaining a DCI field that indicates activation of an SPS or CG. When the terminal 20 receives from the base station 10 a value shown in FIG. 3, which is specified for each DCI format, in addition to the above-described activation conditions, the terminal 20 determines that the SPS or CG has been activated.

[0036] 4 is a diagram for explaining a DCI field that instructs the release of an SPS or CG. When the terminal 20 receives from the base station 10 a value shown in FIG. 4, which is specified for each DCI format, in addition to the above-described activation conditions, the terminal 20 determines that the SPS or CG has been released.

[0037] (Previous problems) Conventionally, when DCI1_1 / 0_1 is configured with a TDRA table including at least one row including multiple SLIVs, that is, when multi-PDSCH scheduling or multi-PUSCH scheduling is enabled, the following problem occurs.

[0038] The first problem is that it is not clear whether DCI1_1 / 0_1 allows activating the configuration of SPS-PDSCH or CG-PUSCH, and if it does, the details of reception or transmission of SPS-PDSCH or CG-PUSCH are not specified.

[0039] The second problem is that it is not clear whether DCI1_1 / 0_1 allows deactivating (releasing) the SPS-PDSCH or CG-PUSCH configuration.

[0040] (Outline of this embodiment) Therefore, in this embodiment, a method for activating or releasing an SPS-PDSCH or CG-PUSCH configuration when multi-PDSCH scheduling or multi-PUSCH scheduling is enabled will be described. Hereinafter, examples 1 to 3 will be described as specific examples.

[0041] Example 1 In this embodiment, a method for activating an SPS-PDSCH or a CG-PUSCH will be described. If DCI1_1 / 0_1 is configured with a TDRA table including at least one row including multiple SLIVs, i.e., if multi-PDSCH scheduling or multi-PUSCH scheduling is enabled, the terminal 20 may perform one of the following optional operations:

[0042] <Option 1> The terminal 20 assumes that DCI1_1 / 0_1 does not activate an SPS-PDSCH or CG-PUSCH configuration. For example, when a TDRA table including at least one row including multiple SLIVs is configured, the terminal 20 may interpret that even if DCI1_1 / 0_1 notifies a bit string combination that indicates activation of an SPS-PDSCH or CG-PUSCH, it is notifying activation of an SPS-PDSCH or CG-PDSCH but normal dynamic PDSCH or PDSCH resource allocation.

[0043] <Option 2> When the terminal 20 receives DCI1_1 / 0_1 from the base station 10 and activates the SPS-PDSCH or CG-PUSCH configuration, it is assumed that the row of the TDRA indicated by the SPS / CG activation DCI1_1 / 0_1 does not include multiple SLIVs.

[0044] In this case, the terminal 20 determines the time domain resource allocation of the activated SPS-PDSCH or CG-PUSCH configuration according to one SLIV indicated in a row of the TDRA.

[0045] Note that the terminal 20 may assume that a row of the TDRA indicated by the activation DCI1_1 / 0_1 does not include multiple valid SLIVs. A valid SLIV may mean, for example, that the SPS-PDSCH resource allocated by the SLIV is a resource allocated as a downlink signal in a TDD (Time Division Duplex) setting.

[0046] Therefore, if the SPS-PDSCH resources allocated by the SLIV are resources allocated as an uplink signal in the TDD configuration, the terminal 20 may determine that the SLIV is invalid.

[0047] The terminal 20 determines the subsequent time domain resource allocation of the activated SPS-PDSCH or CG-PUSCH configuration according to one valid SLIV indicated in a row of the TDRA.

[0048] <Option 3> When the terminal 20 receives DCI1_1 / 0_1 from the base station 10 and activates the SPS-PDSCH or CG-PUSCH configuration, and the row of the TDRA indicated by the activation DCI1_1 / 0_1 contains multiple (or multiple valid) SLIVs, it operates in one of the following options:

[0049] <Option 3-1> The terminal 20 may use only one SLIV for receiving or transmitting an activated SPS-PDSCH or CG-PUSCH configuration. For example, the terminal 20 may use an SLIV that configures the first, last, longest, or shortest resource among the SLIVs of the indicated TDRA row.

[0050] The terminal 20 may determine whether the SLIV is the first or last resource setting SLIV based on the slot offset (k0 or k2) associated with the SLIV. The longest or shortest resource is determined based on the length of the resource in the time direction.

[0051] <Option 3-2> Terminal 20 may use multiple SLIVs for receiving or transmitting activated SPS-PDSCH or CG-PUSCH configurations, i.e., terminal 20 may receive a PDSCH or transmit a PUSCH using multiple resources configured by multiple SLIVs.

[0052] The terminal 20 may further perform the actions shown in any of the following schemes.

[0053] <Plan 1> The terminal 20 may use all SLIVs for reception or transmission of the activated SPS-PDSCH or CG-PUSCH configuration, i.e., the terminal 20 may receive the PDSCH or transmit the PUSCH using all resources configured by multiple SLIVs.

[0054] <Plan 2> The terminal 20 may use a plurality of SLIVs not exceeding X for reception or transmission of an activated SPS-PDSCH or CG-PUSCH configuration. X is, for example, 2.

[0055] <Option 2-A> X may be a fixed value defined by a specification or RRC configuration.

[0056] If the number of SLIVs in a row of the indicated TDRA is less than or equal to X, the terminal 20 may use all SLIVs included in a row of the indicated TDRA for receiving or transmitting an activated SPS-PDSCH or CG-PUSCH configuration.

[0057] If the number of SLIVs in a row of the indicated TDRA is greater than X, the X SLIVs that configure the first / last resources or the X SLIVs that configure the longest / shortest resources of the SLIVs in the indicated TDRA row may be used for receiving or transmitting the activated SPS-PDSCH or CG-PUSCH configuration.

[0058] <Plan 2-B> X may not be a fixed value, but may be a value determined by the period of the SPS or CG and the range of the SLIV included in one row of the TDRA.

[0059] If all SLIVs included in one row of the indicated TDRA are within one SPS or CG period, the terminal 20 may use all SLIVs included in one row of the indicated TDRA for receiving or transmitting an activated SPS-PDSCH or CG-PUSCH configuration.

[0060] Also, if all SLIVs included in one row of the indicated TDRA exceed the current SPS or CG period, the terminal 20 may use only the SLIVs within the current SPS or CG period for receiving or transmitting the activated SPS-PDSCH or CG-PUSCH configuration.

[0061] The terminal 20 may operate by combining the above-described scheme 2-A and scheme 2-B.

[0062] Example 2 In this embodiment, a method for releasing (deactivating) an SPS-PDSCH or a CG-PUSCH will be described. If DCI1_1 / 0_1 is configured with a TDRA table including at least one row including multiple SLIVs, i.e., if multi-PDSCH scheduling or multi-PUSCH scheduling is enabled, the terminal 20 may perform one of the following optional operations.

[0063] <Option 1> Terminal 20 may assume that DCI1_1 / 0_1 does not release one SPS-PDSCH or CG-PUSCH configuration. Terminal 20 may also assume that DCI1_1 / 0_1 does not release multiple SPS-PDSCH or CG-PUSCH configurations. Note that multiple SPS-PDSCH or CG-PUSCH configurations may be configurations using multiple resources configured by multiple SLIVs, as shown in option 3-2 or option 3-3 in the first embodiment, for example.

[0064] For example, when a TDRA table including at least one row including multiple SLIVs is configured, even if DCI1_1 / 0_1 notifies a combination of bit strings indicating the release of an SPS-PDSCH or CG-PUSCH, the terminal 20 may interpret this as notifying a normal dynamic PDSCH or PDSCH resource allocation rather than the release of an SPS-PDSCH or CG-PDSCH.

[0065] <Option 2> When the terminal 20 receives DCI1_1 / 0_1 from the base station 10 and releases one SPS-PDSCH or CG-PUSCH configuration, and / or when it releases multiple SPS-PDSCH or CG-PUSCH configurations, it is assumed that the row of the TDRA indicated by the SPS / CG release DCI1_1 / 0_1 does not include multiple SLIVs.

[0066] Note that the terminal 20 may assume that the row of the TDRA indicated by the release DCI1_1 / 0_1 does not include multiple valid SLIVs.

[0067] <Option 3> The terminal 20 may assume that DCI1_1 / 0_1 releases one SPS-PDSCH or CG-PUSCH configuration, or may assume that DCI1_1 / 0_1 releases multiple SPS-PDSCH or CG-PUSCH configurations, or may assume that a row of the TDRA indicated by the SPS / CG release DCI1_1 / 0_1 includes multiple (or multiple valid) SLIVs.

[0068] Example 3 In this embodiment, a DCI field for activating or releasing the SPS-PDSCH or CG-PUSCH configuration when multi-PDSCH scheduling or multi-PUSCH scheduling is enabled will be described.

[0069] <Option 1> If DCI1_1 / 0_1 can be used to activate the SPS-PDSCH or CG-PUSCH configuration (i.e., option 2 and / or option 3 in Example 1), the NDI field included in the DCI for enabling scheduling activation may have the following values:

[0070] In the case of a DCI that activates an SPS in one DL and a type 2 CG in one UL, if the terminal 20 is provided with an SPS in one DL or a type 2 CG configuration in one UL, the activation condition may be that in addition to the HPN and RV fields, all NDI bits of DCI1_1 / 0_1 are set to "0".

[0071] In addition, in the case of activation by DCI that activates SPS in one or more DLs or Type 2 CG in UL, if terminal 20 is provided with multiple SPS in DLs or Type 2 CG settings in UL, in addition to the RV field, the activation condition may be that all NDI bits of DCI1_1 / 0_1 are set to "0".

[0072] <Option 2> If DCI1_1 / 0_1 can be used to release the SPS-PDSCH or CG-PUSCH configuration (i.e., option 2 and / or option 3 in Example 2), the NDI field included in the DCI to enable the release of scheduling may have the following values:

[0073] In the case of a DCI that releases an SPS in one DL and a type 2 CG in one UL, when the terminal 20 is provided with an SPS in one DL or a type 2 CG setting in one UL, the activation condition may be that in addition to the HPN, RV, MCS and FDRA fields, the NDI bits of DCI1_1 / 0_1 are all set to "0".

[0074] In addition, in the case of activation by DCI that releases SPS in one or more DLs or Type 2 CG in UL, if terminal 20 is provided with multiple SPS in DLs or Type 2 CG settings in UL, the activation condition may be that in addition to the RV, MCS and FDRA fields, the NDI bits of DCI1_1 / 0_1 are all set to "0".

[0075] In this embodiment, DCI1_1 / 0_1 may be replaced with another DCI format that can include at least one or more rows of a TDRA table that include multiple SLIVs.

[0076] Each option described in each of the above embodiments may be limited to a specific frequency range, for example, FR2-2 (52.6-71 GHz band).

[0077] Each of the options described in each of the above embodiments may be limited to a particular subcarrier spacing, for example, 120 and / or 480 and / or 960 kHz SCS.

[0078] Each option described in each of the above embodiments may be one of the following. - Set by upper layer parameters. Reported by the terminal 20 as terminal capabilities. - To be stated in the specifications. Determined by higher layer parameter settings and reported device capabilities (a combination of the above decisions).

[0079] The terminal 20 may transmit to the base station 10 information indicating at least one of the following terminal capabilities: Terminal capability indicating whether single DCI-based multi-PDSCH / PUSCH scheduling is supported Terminal capability indicating whether to support single DCI-based multi-PDSCH / PUSCH scheduling by activating SPS-PDSCH or CG-PUSCH configuration according to the DCI format configured in the TDRA table that includes at least one row containing multiple SLIVs. Terminal capability indicating whether it supports reception or transmission of SPS-PDSCH or CG-PUSCH configurations with multiple SLIVs activated Terminal capability indicating whether to support the release (deactivation) of SPS-PDSCH or CG-PUSCH configuration by DCI format configured in a TDRA table that contains at least one row containing multiple SLIVs

[0080] (Device configuration) Next, a description will be given of an example of the functional configuration of the base station 10 and the terminal 20 that execute the processes and operations described above.

For example, the methods described in this disclosure present elements of various steps using an example order and are not limited to the particular order presented.

[0117] In this specification, a specific operation that is described as being performed by the base station 10 may also be performed by its upper node in some cases. In a network consisting of one or more network nodes having the base station 10, it is clear that various operations performed for communication with the terminal 20 may be performed by at least one of the base station 10 and another network node other than the base station 10 (such as, but not limited to, an MME or an S-GW). Although the above example illustrates a case where there is one other network node other than the base station 10, the other network node may be a combination of multiple other network nodes (such as an MME and an S-GW).

[0118] The information or signals described in the present disclosure may be output from a higher layer (or a lower layer) to a lower layer (or a higher layer), or may be input / output via multiple network nodes.

For example, data, instructions, commands, information, signals, bits, symbols, chips, etc. that may be referred to throughout the above description may be represented by voltages, currents, electromagnetic waves, magnetic fields or magnetic particles, optical fields or photons, or any combination thereof.

[0124] Note that terms explained 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 a channel and a symbol may be a signal (signaling). Furthermore, a signal may be a message. Furthermore, a component carrier (CC) may be called a carrier frequency, a cell, a frequency carrier, etc.

[0125] As used in this disclosure, the terms "system" and "network" are used interchangeably.

[0126] Furthermore, the information, parameters, etc. described in the present disclosure may be expressed using absolute values, may be expressed using relative values ​​from a predetermined value, or may be expressed using other corresponding information. For example, a radio resource may be indicated by an index.

[0127] The names used for the above-described parameters are not intended to be limiting in any way. Furthermore, the mathematical expressions using these parameters may differ from those explicitly disclosed in this disclosure. The various channels (e.g., PUCCH, PDCCH, etc.) and information elements may be identified by any suitable names, and therefore the various names assigned to these various channels and information elements are not intended to be limiting in any way.

[0128] In this disclosure, terms such as "base station (BS)," "radio 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.

[0129] A base station can accommodate one or more (e.g., three) cells. When a base station accommodates multiple cells, the overall coverage area of ​​the base station can be divided into multiple smaller areas, and each smaller area can be provided with communication service by a base station subsystem (e.g., a small indoor base station (RRH: Remote Radio Head)). The term "cell" or "sector" refers to a part or the entire coverage area of ​​a base station and / or base station subsystem that provides communication service within this coverage.

[0130] In this disclosure, the terms "Mobile Station (MS)," "user terminal," "User Equipment (UE)," "terminal," etc. may be used interchangeably.

[0131] 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 some other suitable terminology.

[0132] 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, or the mobile body itself. 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 also include devices that do not necessarily move during communication operations. For example, at least one of the base station and the mobile station may be an IoT (Internet of Things) device such as a sensor.

[0133] Furthermore, a base station in the present disclosure may be read as a user terminal. For example, the aspects / embodiments of the present disclosure may be applied to a configuration in which communication between a base station and a user terminal is replaced with communication between a plurality of terminals 20 (which may be called, for example, D2D (Device-to-Device) or V2X (Vehicle-to-Everything)). In this case, the terminal 20 may be configured to have the functions of the base station 10 described above. Furthermore, terms such as "uplink" and "downlink" may be read as terms corresponding to terminal-to-terminal communication (for example, "side"). For example, terms such as an uplink channel and a downlink channel may be read as a side channel.

[0134] Similarly, the user terminal in the present disclosure may be read as a base station, in which case the base station may be configured to have the functions of the user terminal described above.

[0135] As used in this disclosure, the terms "determining" and "determining" may encompass a wide variety of actions. "Determining" and "determining" may include, for example, judging, calculating, computing, processing, deriving, investigating, looking up, searching, inquiring (e.g., searching in a table, database, or other data structure), ascertaining, and the like. "Determining" and "determining" may also include receiving (e.g., receiving information), transmitting (e.g., sending information), input, output, accessing (e.g., accessing data in memory), and the like. Furthermore, "judgment" and "decision" can include regarding resolving, selecting, choosing, establishing, comparing, etc. as having been "judged" or "decided." In other words, "judgment" and "decision" can include regarding some action as having been "judged" or "decided." Furthermore, "judgment (decision)" can be interpreted as "assuming," "expecting," "considering," etc.

[0136] The terms "connected," "coupled," or any variation thereof, refer to 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" to each other. The coupling or connection between elements may be physical, logical, or a combination thereof. For example, "connected" may be read as "access." As used in this disclosure, two elements may be considered to be "connected" or "coupled" to each other using one or more wires, cables, and / or printed electrical connections, as well as electromagnetic energy having wavelengths in the radio frequency range, microwave range, and optical (both visible and invisible) range, as some non-limiting and non-exhaustive examples.

[0137] The reference signal may be abbreviated as RS (Reference Signal) or may be called a pilot depending on the applicable standard.

[0138] As used in this disclosure, the phrase "based on" does not mean "based only on," unless expressly stated otherwise. In other words, the phrase "based on" means both "based only on" and "based at least on."

[0139] As used in this disclosure, any reference to an element using a designation such as "first," "second," etc. does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Thus, a reference to a first and a second element does not imply that only two elements may be employed or that the first element must in some way precede the second element.

[0140] The "means" in the configuration of each of the above devices may be replaced with "part," "circuit," "device," etc.

[0141] When used in this disclosure, the terms "include," "including," and variations thereof are intended to be inclusive, similar to the term "comprising." Furthermore, when used in this disclosure, the term "or" is not intended to be an exclusive or.

[0142] A radio frame may be composed of one or more frames in the time domain. Each of the one or more frames in the time domain may be called a subframe. A subframe may further be composed 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.

[0143] Numerology may be communication parameters that apply to at least one of transmission and reception of a signal or channel, such as subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame structure, specific filtering operations performed by the transceiver in the frequency domain, and specific windowing operations performed by the transceiver in the time domain.

[0144] A slot may be composed of one or more symbols (such as an Orthogonal Frequency Division Multiplexing (OFDM) symbol or a Single Carrier Frequency Division Multiple Access (SC-FDMA) symbol) in the time domain. A slot may be a time unit based on numerology.

[0145] A slot may include multiple minislots. Each minislot may consist of one or multiple symbols in the time domain. A minislot may also be called a subslot. A minislot 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.

[0146] The radio frame, subframe, slot, minislot, and symbol all represent time units for transmitting signals, and may be referred to by other names corresponding to the radio frame, subframe, slot, minislot, and symbol.

[0147] 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 minislot may be called a TTI. That is, at least one of the subframe and the TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (for example, 1-13 symbols), or a period longer than 1 ms. Note that the unit representing the TTI may be called a slot, minislot, etc. instead of a subframe.

[0148] Here, TTI refers to, for example, the smallest time unit for scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling to allocate wireless resources (such as frequency bandwidth and transmission power that can be used by each terminal 20) to each terminal 20 in TTI units. Note that the definition of TTI is not limited to this.

[0149] The TTI may be a transmission time unit for a channel-encoded data packet (transport block), a code block, a code word, etc., or may be a processing unit for scheduling, link adaptation, etc. When a TTI is given, the time interval (e.g., the number of symbols) to which a transport block, a code block, a code word, etc. is actually mapped may be shorter than the TTI.

[0150] When one slot or one minislot is called a TTI, one or more TTIs (i.e., one or more slots or one or more minislots) may be the minimum time unit for scheduling. Also, the number of slots (minislots) constituting the minimum time unit for scheduling may be controlled.

[0151] A TTI having a time length of 1 ms may be called a regular TTI (TTI in LTE Rel. 8-12), normal TTI, long TTI, regular subframe, normal subframe, long subframe, slot, etc. A TTI shorter than a regular TTI may be called a shortened TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, minislot, subslot, slot, etc.

[0152] In addition, a long TTI (e.g., a normal TTI, a subframe, etc.) may be interpreted as a TTI having a time length of more than 1 ms, and a short TTI (e.g., a shortened TTI, etc.) may be interpreted as a TTI having a TTI length shorter than the TTI length of a long TTI and equal to or greater than 1 ms.

[0153] A resource block (RB) is a resource allocation unit in the time domain and frequency domain, and may include one or more consecutive subcarriers in the frequency domain. The number of subcarriers included in an RB may be the same regardless of numerology, for example, 12. The number of subcarriers included in an RB may also be determined based on numerology.

[0154] The time domain of an RB may include one or more symbols and may have a length of one slot, one minislot, one subframe, or one TTI. One TTI, one subframe, etc. may each be composed of one or more resource blocks.

[0155] Note that one or more RBs may also be called a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, or the like.

[0156] Furthermore, a resource block may be composed of one or more resource elements (REs). For example, one RE may be a radio resource region of one subcarrier and one symbol.

[0157] A Bandwidth Part (BWP) (which may also be referred to as a fractional bandwidth) may represent a subset of contiguous common resource blocks (RBs) for a given numerology on a given carrier, where the common RBs may be identified by their index relative to a common reference point of the carrier. PRBs may be defined in a given BWP and numbered within that BWP.

[0158] The BWP may include a BWP for UL (UL BWP) and a BWP for DL ​​(DL BWP). One or more BWPs may be set for the terminal 20 within one carrier.

[0159] At least one of the configured BWPs may be active, and the terminal 20 may not expect to transmit or receive a predetermined signal / channel outside the active BWP. Note that the terms "cell," "carrier," and the like in this disclosure may be read as "BWP."

[0160] The above-described structures of radio frames, subframes, slots, minislots, symbols, etc. are merely examples. For example, the number of subframes included in a radio frame, the number of slots per subframe or radio 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, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, etc. may be changed in various ways.

[0161] In this disclosure, where articles are added by translation, such as a, an, and the in English, the disclosure may include that the nouns following these articles are in the plural form.

[0162] In the present 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 "coupled" may also be interpreted in the same way as "different."

[0163] Each aspect / embodiment described in this disclosure may be used alone, in combination, or switched depending on the implementation. Furthermore, notification of predetermined information (e.g., notification that "X is true") is not limited to being done explicitly, but may be done implicitly (e.g., by not notifying the predetermined information).

[0164] Although the present disclosure has been described in detail above, it is 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 spirit and scope of the present disclosure as defined by the claims. Therefore, the description of the present disclosure is intended to be illustrative and does not have any limiting meaning on the present disclosure. [Explanation of symbols]
