Description

Terminal and communication method

[0001] The present invention relates to a terminal and a communication method in a wireless communication system.

[0002] The 3GPP (registered trademark) (3rd Generation Partnership Project) is currently studying a wireless communication method called 5G or NR (New Radio) (hereinafter, this wireless communication method will be referred to as "NR") in order to achieve a larger system capacity, a higher data transmission speed, and a lower latency in wireless sections. In 5G, various wireless technologies and network architectures are being studied to meet the requirements of achieving a throughput of 10 Gbps or more while reducing the latency in wireless sections to 1 ms or less (for example, Non-Patent Document 1 and Non-Patent Document 2).

[0003] Furthermore, various requirements are being considered for the next generation, 6G, such as ultra broadband communication, mission critical communication, ultra massive connection, universal coverage, intelligent connection, and ubiquitous sensing.

[0004] To achieve these requirements, new concepts include extensibility (e.g., making it more future-proof), easy-operational, customizable (e.g., making it easier to operate), and sustainability (e.g., reducing costs, having a more robust configuration, and being resilient). Also, guaranteed communication, which always guarantees a minimum level of performance, is being considered.

[0005] 3GPP TS 38.300 V17.5.0 (2023-06)3GPP TS 38.401 V17.5.0 (2023-06)3GPP TS 38.213 V17.6.0 (2023-06)3GPP TS 38.331 V17.5.0 (2023-06)3GPP TS 38.214 V17.6.0 (2023-06)3GPP TS 38.211 V17.5.0 (2023-06)

[0006] For example, in frequency bands using higher frequencies than conventionally, larger subcarrier spacing is used, and since the length of symbols and slots becomes shorter with larger subcarrier spacing, it is necessary to configure the channel or signal appropriately for the subcarrier spacing.

[0007] The present invention has been made in view of the above points, and has as its object to transmit and receive channels or signals that apply larger subcarrier spacing in a wireless communication system.

[0008] According to the disclosed technology, a terminal is provided that has a control unit that assumes scheduling of a shared channel in block units consisting of multiple symbols or multiple slots in communications that apply subcarrier spacing exceeding a certain frequency, and a communication unit that receives or transmits the shared channel from a base station in the communications.

[0009] According to the disclosed technology, it is possible to transmit and receive channels or signals that employ larger subcarrier spacing in a wireless communication system.

[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 the operation of the wireless communication system according to the embodiment of the present invention, existing technology is used as appropriate. However, the existing technology is, for example, the existing LTE, but is not limited to the existing 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] In addition, in the embodiments of the present invention described below, terms such as SS (Synchronization signal), PSS (Primary SS), SSS (Secondary SS), PBCH (Physical broadcast channel), PRACH (Physical random access channel), PDCCH (Physical Downlink Control Channel), PDSCH (Physical Downlink Shared Channel), PUCCH (Physical Uplink Control Channel), and PUSCH (Physical Uplink Shared Channel) used in existing LTE are used. This is for convenience of description, and similar signals, functions, etc. may be called by other names. In addition, the above-mentioned terms in NR correspond to NR-SS, NR-PSS, NR-SSS, NR-PBCH, NR-PRACH, etc. However, even if a signal is used in NR, it is not necessarily stated as "NR-".

[0014] Furthermore, in the embodiment of the present invention, the duplex method may be a time division duplex (TDD) method, a frequency division duplex (FDD) method, or another method (for example, flexible duplex, etc.).

[0015] Furthermore, in the embodiments of the present invention, "configuring" radio parameters etc. may mean that predetermined values ​​are pre-configured, or that radio parameters notified from the base station 10 or the terminal 20 are set.

[0016] Fig. 1 is a diagram showing an example of the configuration of a wireless communication system according to an embodiment of the present invention. As shown in Fig. 1, the wireless communication system according to the 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. 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. 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, for example, transmitted via NR-PBCH and is also referred to as broadcast information. The synchronization signal and system information may also be referred to as 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 can apply 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: Secondary Cell) and a primary cell (PCell: Primary Cell) using CA (Carrier Aggregation). Furthermore, the terminal 20 may communicate 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).

[0018] 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 propagation path quality based on the reception results of the reference signals.

[0019] Furthermore, various requirements are being considered for the next generation, 6G, such as ultra broadband communication, mission critical communication, ultra massive connection, universal coverage, intelligent connection, and ubiquitous sensing.

[0020] To achieve these requirements, new concepts include extensibility (e.g., making it more future-proof), easy-operational, customizable (e.g., making it easier to operate), and sustainability (e.g., reducing costs, having a more robust configuration, and being resilient). Also, guaranteed communication, which always guarantees a minimum level of performance, is being considered.

[0021] 2 is a diagram showing an example of PDCCH monitoring according to an embodiment of the present invention. In the example shown in FIG. 2, all search spaces (SS) of the PDCCH may be monitored for the same time length as one slot with a 120 kHz SCS, one out of four slots with a 480 kHz SCS, or one out of eight slots with a 960 kHz SCS. Note that only a specific search space may be monitored in the other three slots with a 480 kHz SCS and the other seven slots with a 960 kHz SCS.

[0022] Table 1 shows the number of serving cells and combinations (X Ｓ , Y Ｓ ) for each X Ｓ indicates the maximum number of monitored PDCCH candidates in a group of slots (see Non-Patent Document 3). Ｓ indicates the slot in which all search spaces are monitored.

[0023]

[0024] Table 2 shows the results for each serving cell and combination (X Ｓ , Y Ｓ ) for each X Ｓ It indicates the maximum number of non-overlapping Control Channel Elements (CCEs) in a group of slots (see Non-Patent Document 3).

[0025]

[0026] In Tables 1 and 2, the (X Ｓ , Y Ｓ ) = (4, 1), 960 kHz SCS, that is, μ = 6 (X Ｓ , Y Ｓ The setting of ) = (8, 1) corresponds to Figure 2. With this setting, the same number of PDCCH candidates (20) and the number of non-overlapping CCEs (32) are set in one slot with 120 kHz SCS, four slots with 480 kHz SCS, and eight slots with 960 kHz SCS.

[0027] 3 is a diagram showing an example of multi-PDSCH scheduling in an embodiment of the present invention. Table 3 is an example of a TDRA (Time Domain Resource Allocation) table. The TDRA table in Table 3 supports multi-PDSCH scheduling.

[0028]

[0029] For example, as shown in Figure 3, Row index 0 in Table 3 can schedule PDSCH #1 with offset 2, starting symbol #0, and length 12 symbols, and PDSCH #2 with offset 4, starting symbol #0, and length 14 symbols. Furthermore, HARQ-ACK information for PDSCH #1 and PDSCH #2 is transmitted offset K1 from PDSCH #2.

[0030] FIG. 4 is a diagram showing an example of TBoMS according to an embodiment of the present invention. In time resource allocation for TBoMS (Transport Block Processing over Multiple Slots), one transport block is allocated across multiple slots. FIG. 4 shows an example in which one transport block is allocated across four slots. The number N of slots in which one transport block is allocated is notified by base station 10 using the information element numberOfSlotsTBoMS. In TBoMS, the symbol allocation within each slot may be the same.

[0031] Here, an SCS exceeding 960 kHz may be introduced for a frequency band exceeding 71 GHz, for example. In a larger SCS, the symbol length and slot length become even shorter. In consideration of the shorter symbol length and slot length, the terminal 20 or the base station 10 may perform the following operations 1) to 4).

[0032] 1) It may determine which channels or signals to apply a higher SCS to, for example, SSB, PDCCH, PDSCH, PUSCH, and PUCCH.

[0033] 2) It may be possible to relax the ability to monitor PDCCHs with higher SCS, for example by increasing the PDCCH monitoring capability per multiple slots and the number of slots in a slot group.

[0034] 3) For PDSCH and / or PUSCH scheduling with a higher SCS, more PDSCH and / or PUSCH may be schedulable by a single DCI. The granularity of PDSCH and / or PUSCH scheduling may be increased. For example, scheduling may be possible on a symbol or slot group basis. For example, TBoMS for PDSCH and / or PUSCH may be enhanced.

[0035] 4) New timeline parameters for the SCS may be defined and applied to communications.

[0036] The terminal 20 and / or the base station 10 may perform the following operations 1) to 7).

[0037] Operation 1) In a specific use case, SCS above 960 kHz may be supported. For example, the specific use case may be a use of a frequency band above 71 GHz or a use of NTN.

[0038] The new SCS value is 2 of 15 kHz. μ It may be a scaled value by a power, i.e., new SCS=2 μ 15 kHz, where μ may be an integer greater than or equal to 7. For example, a 1920 kHz SCS may be supported with μ = 7, a 3840 kHz SCS with μ = 8, and a 7680 kHz SCS with μ = 9. Note that the slot boundaries of all smaller SCSs may always align with the slot boundaries of all larger SCSs.

[0039] The new SCS value may also be a value obtained by scaling 15 kHz, 30 kHz, 60 kHz, 120 kHz, 240 kHz, 480 kHz, or 960 kHz by M times.

[0040] For example, the new SCS may be M x 15 kHz, where M may be an integer greater than or equal to 65. Note that the slot boundaries of the 15 kHz SCS may always be aligned with the slot boundaries of the new SCS. The slot boundaries of the 30 kHz, 60 kHz, 120 kHz, 240 kHz, 480 kHz, or 960 kHz SCS may or may not be aligned with the slot boundaries of the new SCS. The slot boundaries of a smaller SCS may or may not be aligned with the slot boundaries of a larger SCS.

[0041] For example, the new SCS may be M x 30 kHz, where M may be an integer greater than or equal to 33. The slot boundaries of the 15 kHz SCS and the 30 kHz SCS may always be aligned with the slot boundaries of the new SCS. The slot boundaries of the 60 kHz, 120 kHz, 240 kHz, 480 kHz, or 960 kHz SCS may or may not be aligned with the slot boundaries of the new SCS. The slot boundaries of a smaller SCS may or may not be aligned with the slot boundaries of a larger SCS.

[0042] For example, the new SCS may be M x 60 kHz, where M may be an integer greater than or equal to 17. The slot boundaries of the 15 kHz, 30 kHz, and 60 kHz SCSs may always be aligned with the slot boundaries of the new SCS. The slot boundaries of the 120 kHz, 240 kHz, 480 kHz, or 960 kHz SCSs may or may not be aligned with the slot boundaries of the new SCS. The slot boundaries of a smaller SCS may or may not be aligned with the slot boundaries of a larger SCS.

[0043] For example, the new SCS may be M x 120 kHz, where M may be an integer greater than or equal to 9. The slot boundaries of the 15 kHz, 30 kHz, 60 kHz, and 120 kHz SCSs may always be aligned with the slot boundaries of the new SCS. The slot boundaries of the 240 kHz, 480 kHz, or 960 kHz SCSs may or may not be aligned with the slot boundaries of the new SCS. The slot boundaries of a smaller SCS may or may not be aligned with the slot boundaries of a larger SCS.

[0044] For example, the new SCS may be M x 240 kHz, where M may be an integer greater than or equal to 5. The slot boundaries of the 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz SCSs may always be aligned with the slot boundaries of the new SCS. The slot boundaries of the 480 kHz or 960 kHz SCS may or may not be aligned with the slot boundaries of the new SCS. The slot boundaries of a smaller SCS may or may not be aligned with the slot boundaries of a larger SCS.

[0045] For example, the new SCS may be M x 480 kHz, where M may be an integer greater than or equal to 3. The slot boundaries of the 15 kHz, 30 kHz, 60 kHz, 120 kHz, 240 kHz, and 480 kHz SCSs may always be aligned with the slot boundaries of the new SCS. The slot boundaries of the 960 kHz SCS may or may not be aligned with the slot boundaries of the new SCS. The slot boundaries of a smaller SCS may or may not be aligned with the slot boundaries of a larger SCS.

[0046] For example, the new SCS may be M x 960 kHz, where M may be an integer greater than or equal to 2. Note that the slot boundaries of the 15 kHz SCS, 30 kHz SCS, 60 kHz SCS, 120 kHz SCS, 240 kHz SCS, 480 kHz SCS, and 960 kHz SCS may always be aligned with the slot boundaries of the new SCS. The slot boundaries of a smaller SCS may or may not be aligned with the slot boundaries of a larger SCS.

[0047] Note that M may be a value expressed as a power of 2. For example, the above M is 2 Ｍ may be replaced by

[0048] By the above operation 1), the higher SCS value can be appropriately determined.

[0049] Action 2) SCS above 960 kHz may or may not be supported for SSB and / or PDCCH and / or PUCCH and / or PDSCH and / or PUSCH and / or PRACH.

[0050] For example, SCS above 960 kHz may be supported only for PDSCH and PUSCH, and not for other channels or signals.

[0051] For example, SCS above 960 kHz may be supported for PDCCH, PUCCH, PDSCH, PUSCH and PRACH, but not for SSB.

[0052] For example, SCS above 960 kHz may be supported for PDCCH, PUCCH, PDSCH and PUSCH, but not for SSB or PRACH.

[0053] For example, SCS above 960 kHz may be supported for channels in RRC_CONNECTED mode, but not for channels in RRC_IDLE and / or RRC_INACTIVE modes.

[0054] For example, SCS above 960 kHz may be supported only for DL ​​signals and / or DL ​​channels (e.g., PDSCH).

[0055] For example, SCS above 960 kHz may be supported only for UL signals and / or UL channels (e.g., PUSCH).

[0056] For example, SCS above 960 kHz may be supported only for SSB.

[0057] By the above operation 2), it is possible to appropriately determine the channel or signal to which the higher SCS is applied.

[0058] Operation 3) For SCS above 960 kHz, multi-slot PDCCH monitoring capability and / or monitoring capability restriction (e.g., setting monitoringCapabilityConfig to r17monitoringcapability (see Non-Patent Document 4)) may be supported.

[0059] Option 1) Same combination as for 480kHz SCS or 960kHz SCS (X Ｓ , Y Ｓ ) values ​​may be supported for SCS above 960 kHz.

[0060] Table 4 shows the results for each serving cell and combination (X Ｓ , Y Ｓ ) for each X Ｓ Indicates the maximum number of monitored PDCCH candidates in a group of slots.

[0061]

[0062] As shown in Table 4, the same combination (X) for 480 kHz SCS or 960 kHz SCS Ｓ , Y Ｓ) values, i.e., (4,1), (4,2), (8,1), (8,4), may be supported. For μ=7, i.e., 1920 kHz SCS, 5 at (4,1), 5 at (4,2), 10 at (8,1), and 10 at (8,4) may be supported. For μ=8, i.e., 3840 kHz, 5 at (8,1) and 5 at (8,4) may be supported.

[0063] Table 5 shows the results for each serving cell and combination (X Ｓ , Y Ｓ ) for each X Ｓ Indicates the maximum number of non-overlapping CCEs in a group of slots.

[0064]

[0065] As shown in Table 5, the same combination (X) for 480 kHz SCS or 960 kHz SCS Ｓ , Y Ｓ ) values, i.e., (4,1), (4,2), (8,1), and (8,4), may be supported. For μ=7, i.e., 1920 kHz SCS, (4,1) may support 8, (4,2) may support 8, (8,1) may support 16, and (8,4) may support 16. For μ=8, i.e., 3840 kHz, (4,1) may support 4, (4,2) may support 4, (8,1) may support 8, and (8,4) may support 8.

[0066] Option 2) New Combination (X Ｓ , Y Ｓ ) values ​​may be supported for SCS above 960 kHz. For example, X Ｓ may be larger than the value for SCS below 960 kHz.

[0067] Table 6 shows the results for each serving cell and combination (X Ｓ , Y Ｓ ) for each X Ｓ Indicates the maximum number of monitored PDCCH candidates in a group of slots.

[0068]

[0069] As shown in Table 6, the new combination (X Ｓ , YＳ ) values, i.e., (16,1), (16,8), may be supported. For μ=7, i.e., 1920 kHz SCS, 20 may be supported at (16,1) and 20 at (16,8). For μ=8, i.e., 3840 kHz, 10 may be supported at (16,1) and 10 at (16,8).

[0070] Table 7 shows the results for each serving cell and combination (X Ｓ , Y Ｓ ) for each X Ｓ Indicates the maximum number of non-overlapping CCEs in a group of slots.

[0071]

[0072] As shown in Table 7, the new combination (X Ｓ , Y Ｓ ) values, i.e., (16,1), (16,8), may be supported. For μ=7, i.e., 1920 kHz SCS, 32 may be supported for (16,1) and 32 for (16,8). For μ=8, i.e., 3840 kHz, 16 may be supported for (16,1) and 16 for (16,8).

[0073] Note that a combination of the above option 1) and option 2) may be supported.

[0074] The values ​​in Tables 4, 5, 6 and 7 are examples, and other values ​​may be specified.

[0075] By the above operation 3), the ability to monitor the PDCCH can be appropriately determined and supported depending on the SCS.

[0076] Operation 4) Figure 5 shows an example of multi-PDSCH / PUSCH scheduling in an embodiment of the present invention. Figure 5 shows an example in which a single DCI schedules eight PDSCHs and / or PUSCHs when the SCS is 960 kHz.

[0077] For PDSCHs and / or PUSCHs to which an SCS exceeding 960 kHz is applied, scheduling by a single DCI may be supported in which the maximum number of scheduled PDSCHs and / or PUSCHs exceeds eight.

[0078] In addition, the number of PDSCHs and / or PUSCHs in one slot scheduled by a single DCI or multiple DCIs may be limited to one.

[0079] Multiple repetitions may be supported for each scheduled PDSCH and / or PUSCH or for a specific PDSCH and / or PUSCH. The number of repetitions may be signaled or configured separately for each PDSCH and / or PUSCH. For example, in a certain TDRA row, a separate number of repetitions, repK, may be configured for each SLIV (Start and Length Indicator Value). Alternatively, the number of repetitions may be signaled or configured commonly for all PDSCHs and / or PUSCHs. For example, in a certain TDRA row, one number of repetitions, repK, may be configured for all SLIVs.

[0080] The total number of HARQ processes for PDSCH and / or PUSCH in a serving cell may be greater than 32.

[0081] The above-described operation 4) enables efficient scheduling of the PDSCH and / or PUSCH according to the SCS.

[0082] Operation 5) For a PDSCH and / or a PUSCH to which an SCS higher than 960 kHz is applied, block-based PDSCH and / or PUSCH scheduling may be supported. Block-based PDSCH and / or PUSCH scheduling means that the granularity of time domain resource allocation for PDSCH and / or PUSCH scheduling is a block.

[0083] A block may be X symbols, X slots, X subframes, or X frames. For example, a reference SCS may be defined or configured by RRC signaling, and X may be specified as X = actual SCS / reference SCS. For example, if the reference SCS is 960 kHz and the actual SCS is 1920 kHz, X may be 1920 / 960 = 2. The RRC signaling may be configured for each BWP or for each DCI format (DCI format 0_0, 0_1, 0_2, 0_3, 1_0, 1_1, 1_2, or 1_3).

[0084] For example, the value of X may be defined by a specification or configured by RRC signaling, which may be configured for each BWP or for each DCI format (e.g., DCI format 0_0, 0_1, 0_2, 0_3, 1_0, 1_1, 1_2, or 1_3).

[0085] Furthermore, a block may be defined as a certain period of time. For example, a block may be Y milliseconds, Y seconds, etc. For example, the value of Y may be defined by a specification or configured by RRC signaling. The RRC signaling may be configured for each BWP or for each DCI format (e.g., DCI format 0_0, 0_1, 0_2, 0_3, 1_0, 1_1, 1_2, or 1_3).

[0086] Block-based PDSCH and / or PUSCH scheduling may be enabled as shown below in 1)-5).

[0087] 1) For SCS above 960 kHz, block-based PDSCH and / or PUSCH scheduling may always be enabled.

[0088] 2) Block-based PDSCH and / or PUSCH scheduling may be explicitly configured and enabled by RRC signaling, either per BWP or per DCI format (e.g., DCI format 0_0, 0_1, 0_2, 0_3, 1_0, 1_1, 1_2, or 1_3).

[0089] 3) Whether block-based PDSCH and / or PUSCH scheduling is enabled may be implicitly determined based on whether the reference SCS, X, or Y is configured. For example, if the reference SCS, X, or Y is configured, block-based PDSCH and / or PUSCH scheduling may be enabled.

[0090] 4) Whether block-based PDSCH and / or PUSCH scheduling is enabled may be determined based on the scheduling DCI. For example, a new DCI field indicating whether the scheduling granularity of the PDSCH and / or PUSCH scheduled by the DCI is legacy or block-based may be configured in an existing DCI format to which an existing RNTI is applied. The existing DCI format may be, for example, DCI format 0_0, 0_1, 0_2, 0_3, 1_0, 1_1, 1_2, or 1_3. Furthermore, applying a new RNTI to a new DCI format or an existing DCI format may indicate that the scheduling granularity of the PDSCH and / or PUSCH scheduled by the DCI is block-based.

[0091] 5) Block-based PDSCH and / or PUSCH scheduling may be enabled based on the TDRA table configuration. For example, if the notified TDRA row includes a block-based time domain resource allocation, block-based PDSCH and / or PUSCH scheduling may be enabled. The block-based time domain resource allocation may be a time domain resource allocation using a block-based offset and / or a block-based length.

[0092] 6 is a diagram showing an example of time domain resource allocation in an embodiment of the present invention. Table 8 is a table showing an example of time domain resource allocation in an embodiment of the present invention.

[0093]

[0094] Block-based PDSCH and / or PUSCH scheduling may be performed as shown in FIG. 6 and Table 8, options 1-7.

[0095] In legacy NR, the starting position of the PDSCH and / or PUSCH is specified by an offset K0 / K2 per slot and an offset S per symbol within the slot, and the length of the PDSCH and / or PUSCH is specified by the length L per symbol within the slot.

[0096] In option 1, the starting position of the PDSCH and / or PUSCH is specified by an offset K in slot units and an offset S in symbol units within the slot, and the length of the PDSCH and / or PUSCH is specified by a length L in block units.

[0097] In option 2, the starting position of the PDSCH and / or PUSCH is specified by an offset K in blocks, and the length of the PDSCH and / or PUSCH is specified by a length L in blocks.

[0098] In option 3, the starting position of the PDSCH and / or PUSCH is specified by an offset K in slot units, and the length of the PDSCH and / or PUSCH is specified by a length L in block units.

[0101] In option 6, the starting position of the PDSCH and / or PUSCH is specified by an offset K in block units and an offset S in symbol units within the block, and the length of the PDSCH and / or PUSCH is specified by a length L in block units.

[0102] In option 7, the starting position of the PDSCH and / or PUSCH is specified by an offset K1 in block units, an offset K2 in slot units within the block, and an offset S in symbol units within the slot, and the length of the PDSCH and / or PUSCH is specified by a length L in block units.

[0103] In addition, the block-unit length in each of the above options may be replaced with a slot-unit and / or symbol-unit length. The maximum number of blocks corresponding to the length of one PDSCH and / or PUSCH opportunity may be defined by specifications, configured by RRC signaling, or reported by UE capabilities. For example, the PDSCH and / or PUSCH may be configured to a maximum of 14 blocks.

[0104] Block-based PDSCH and / or PUSCH opportunities may be configured across multiple slots. For a multi-slot PUSCH, transmit power may be determined per slot or across PUSCH opportunities across multiple slots.

[0105] 7 is a diagram showing an example (1) of block-based time domain resource allocation according to an embodiment of the present invention. As shown in FIG. 7, one block may be two slots. The PUSCH length may be one block.

[0106] 8 is a diagram showing an example (2) of block-based time domain resource allocation in an embodiment of the present invention. As shown in Example 1 of Fig. 8, one block may be four symbols, the start position offset may be one block, and the PUSCH length may be four blocks. As shown in Example 2 of Fig. 8, one block may be four symbols, the start position offset may be two symbols, and the PUSCH length may be four blocks.

[0107] Furthermore, when PUSCH scheduling is performed with block-based granularity, frequency hopping may be configured as shown in 1)-2) below. As the frequency hopping method, for example, one of inter-slot frequency hopping, intra-slot frequency hopping, inter-block frequency hopping, intra-block frequency hopping, inter-block group frequency hopping, and intra-block group frequency hopping, or a combination of two or more thereof, may be used. Note that a block group may be composed of two or more groups.

[0108] 1) The PUSCH frequency hopping scheme may be determined based on existing frequency hopping parameters. For example, when intra-slot frequency hopping is configured, signaled, or determined and the PUSCH is scheduled based on block-based granularity, the frequency hopping scheme may be determined as described in a) to c) below.

[0109] a) The UE may apply intra-block frequency hopping to each block of PUSCH opportunities. ｓｙｍｂ ＰＵＳＣＨ，ｓ (See Non-Patent Document 5) may be interpreted as the number of symbols for PUSCH transmission in each block.

[0110] b) The UE may apply intra-block group frequency hopping to each block group of PUSCH opportunities. ｓｙｍｂ ＰＵＳＣＨ，ｓ may be interpreted as the number of blocks for PUSCH transmission in each block group.

[0111] c) The UE may apply intra-slot frequency hopping to each slot of the PUSCH opportunity.

[0112] Also, for example, when inter-slot frequency hopping is configured, notified or determined and PUSH is scheduled based on block-based granularity, the frequency hopping method may be determined as follows: a)-c).

[0113] a) The UE may perform inter-block frequency hopping. The number of slots used for frequency hopping in section 6.3.1 of 3GPP TS 26.24 may be replaced with the number of blocks.

[0114] b) The UE may perform inter-block group frequency hopping. The number of slots used for frequency hopping in section 6.3.1 of 3GPP TS 26.210 may be replaced with the number of block groups.

[0115] c) The UE may apply inter-slot frequency hopping to each slot of the PUSCH.

[0116] 2) An additional parameter may be introduced to set or signal a frequency hopping scheme. For example, the additional parameter may set any one of inter-slot PUSCH frequency hopping, intra-slot PUSCH frequency hopping, inter-block PUSCH frequency hopping, intra-block PUSCH frequency hopping, inter-block group PUSCH frequency hopping, and intra-block group PUSCH frequency hopping, and the corresponding frequency hopping scheme may be applied.

Figure 12 shows an example in which one block has two slots and intra-block group frequency hopping is applied. The hop length is one block. It is assumed that one PUSCH opportunity corresponds to one block group.

[0121] Fig. 13 is a diagram showing an example (4) of frequency hopping according to an embodiment of the present invention. Fig. 13 shows an example in which one block has two slots and inter-slot frequency hopping is applied. The hop length is one slot.

[0122] Fig. 14 is a diagram showing an example (5) of frequency hopping according to an embodiment of the present invention. Fig. 14 shows an example in which one block has two slots and inter-block frequency hopping is applied. The hop length is one block.

[0123] Furthermore, when PUSCH scheduling is performed with block-based granularity, a demodulation reference signal (DMRS) may be determined as shown in 1)-2) below.

[0124] 1) The location of the DMRS may be determined based on scaling. The DMRS table may not be changed. The DMRS may be determined based on scaling as shown in a)-c) below.

[0125] a) The location of the DMRS for PDSCH and / or PUSCH for each slot may be determined. ｄ may correspond to the number of symbols in the slot. Also, the position of the DMRS for PDSCH and / or PUSCH for each block may be determined. In each block, the value l ｄ may correspond to the number of symbols in the block.

[0126] Figure 15 is a diagram showing an example (1) of DMRS allocation according to an embodiment of the present invention. Figure 15 shows an example in which one block has two symbols. Table 9 (see Non-Patent Document 6) is an example of a table for determining the position of the DMRS.

[0127]

[0128] FIG. 15 shows the PUSCH mapping type A in Table 9. ｄ 15 shows an example of the DMRS position when dmrs-AdditionalPosition is pos1 and dmrs-AdditionalPosition is pos1. ｄ = 14, {l ０ , 11}, l ０ If =0, DMRS is placed in symbol #0 and symbol #11 in a slot.

[0129] b) The PDSCH and / or PUSCH opportunity may be divided into X portions, and a DMRS position may be determined in each portion. For example, X may be the number of symbols per block. Each portion may consist of L PDSCH and / or PUSCH symbols, where L may be the number of blocks for PDSCH and / or PUSCH allocation. In each portion, l ｄ The value of may be equal to L, and l ｄ The value of may correspond to the number of symbols in each portion.

[0130] 16 is a diagram showing an example (2) of DMRS allocation according to an embodiment of the present invention. In FIG. 16, an example is shown in which one block has two symbols. In FIG. 16, PUSCH mapping type B, l ｄ 16 shows an example of the DMRS position when dmrs-AdditionalPosition is pos1 and dmrs-AdditionalPosition is pos1. ｄ = 8, {l ０ , 6}, l ０ If L=0 and L=8, the 8 blocks are divided into two parts, and DMRS is placed in symbol #0 and symbol #6 in the first 4 blocks and in symbol #0 and symbol #6 in the last 4 blocks.

[0131] c) Block granularity l ｄ The location of the DMRS may be determined based on scaling by l and l. For example, when determining the location of the DMRS using Table 9, l ｄ may be used as the unit of block number. ０The determined DMRS positions, including the additional DMRS positions, may be interpreted based on the unit of the block for determining the DMRS positions. For example, if the number of blocks for PDSCH and / or PUSCH allocation is L, then ｄ may be used in the table as L. At each determined position of the DMRS, the length of the DMRS may be any of 1 symbol, 2 symbols, 1 block, or 2 blocks.

[0132] 17 is a diagram showing an example (3) of DMRS allocation according to an embodiment of the present invention. In FIG. 17, an example is shown in which one block has two symbols. In FIG. 17, PUSCH mapping type B, l ｄ 10 shows an example of a DMRS position when dmrs-AdditionalPosition is pos1 and dmrs-AdditionalPosition is pos1.

[0133] As shown in FIG. ０ , 6}, and for single-symbol DMRS, the starting symbol of the first DMRS position is l relative to the beginning of the slot for PDSCH and / or PUSCH mapping type A, or the beginning of PDSCH and / or PUSCH mapping type B when frequency hopping is disabled. ０ It becomes the first or last symbol of the th block.

[0134] {l ０ , 6}, and for single-symbol DMRS, the starting symbol of the second DMRS position is, when frequency hopping is enabled, l ０ It becomes the first or last symbol of the th block.

[0135] As shown in FIG. ０ , 6}, and in the case of single-symbol DMRS, the starting symbol of the second DMRS position is the first or last symbol of the block that is the sixth block relative to the start of the slot for PDSCH and / or PUSCH mapping type A or the start of PDSCH and / or PUSCH mapping type B when frequency hopping is disabled.

[0136] {l０ , 6}, and in the case of single symbol DMRS, the starting symbol of the second DMRS position is the first or last symbol of the block, which is the sixth block relative to the beginning of each hop when frequency hopping is enabled.

[0137] As shown in FIG. ０ , 6}, and for single-block DMRS, the starting symbol group of the first DMRS position is l relative to the beginning of a slot for PDSCH and / or PUSCH mapping type A, or the beginning of a slot for PDSCH and / or PUSCH mapping type B when frequency hopping is disabled. ０ This will be the block that becomes the th block.

[0138] {l ０ , 6}, and for single-block DMRS, the starting symbol group of the second DMRS position is, when frequency hopping is enabled, l ０ This will be the block that becomes the th block.

[0139] As shown in FIG. ０ , 6}, and in the case of single-block DMRS, the starting symbol group of the second DMRS position is the block that is the 6th block relative to the start of the slot for PDSCH and / or PUSCH mapping type A, or the start of PDSCH and / or PUSCH mapping type B when frequency hopping is disabled.

[0140] {l ０ , 6}, and in the case of single-block DMRS, the starting symbol group of the second DMRS position is the block that is the 6th block relative to the beginning of each hop when frequency hopping is enabled.

[0141] 2) The DMRS locations may be determined based on an enhanced version of an existing DMRS table, which may be any of Tables 6.4.1.1.3-3, 6.4.1.1.3-4, 6.4.1.1.3-6, 7.4.1.1.2-3, and 7.4.1.1.2-4 in Non-Patent Document 6.

[0142] For example, when determining the location of the DMRS using the DMRS table, ｄ may be used as the unit of symbol number. ０ The determined DMRS positions, including the additional DMRS positions, may be interpreted based on the unit of symbols used to determine the DMRS positions. The length of the PDSCH and / or PUSCH may be greater than 14 symbols in the DMRS table.

[0143] Table 10 is an example of a new DMRS table that enhances the existing DMRS table.

[0144]

[0145] As shown in Table 10, more than 14 ｄ may be supported. ｄ The DMRS location corresponding to may be the same as or different from the existing DMRS location.

[0148] {l ０ , 12}, and for single-symbol DMRS, the starting symbol of the second DMRS position is, when frequency hopping is enabled, l ０ It becomes a symbolic eye symbol.

[0149] As shown in FIG. ０, 12}, and in the case of single-symbol DMRS, the starting symbol of the second DMRS position is the 12th symbol relative to the start of the slot for PDSCH and / or PUSCH mapping type A, or the start of PDSCH and / or PUSCH mapping type B when frequency hopping is disabled.

[0150] {l ０ , 12}, and in the case of single symbol DMRS, the starting symbol of the second DMRS position is the 12th symbol relative to the beginning of each hop when frequency hopping is enabled.

[0151] As shown in FIG. ０ , 12}, and for single-block DMRS, the starting symbol group of the first DMRS position is l relative to the beginning of a slot for PDSCH and / or PUSCH mapping type A, or the beginning of a slot for PDSCH and / or PUSCH mapping type B when frequency hopping is disabled. ０ It becomes a symbolic eye symbol.

[0152] {l ０ , 12}, and for single-block DMRS, the starting symbol group of the second DMRS position is, when frequency hopping is enabled, l ０ It becomes a symbolic eye symbol.

[0153] As shown in FIG. ０ , 12}, and in the case of single block DMRS, the starting symbol group of the second DMRS position is the 12th symbol relative to the start of the slot for PDSCH and / or PUSCH mapping type A, or the start of PDSCH and / or PUSCH mapping type B when frequency hopping is disabled.

[0154] {l ０ , 12}, and in the case of single block DMRS, the starting symbol group of the second DMRS position is the 12th symbol relative to the beginning of each hop when frequency hopping is enabled.

[0155] Operation 5) above allows realizing a DMRS configuration suitable for higher SCS.

[0156] Operation 6) For a BWP to which an SCS higher than 960 kHz is applied, TBoMS may be applied to the PDSCH and / or PUSCH in the BWP. For example, TBoMS as described in 1)-4) below may be applied.

[0159] 3) TBoMS in which a single TB is constructed from a single codeword including a single CB for PDSCH.

[0160] 4) TBoMS, where each TB is composed of two codewords each containing a single CB and / or multiple CBs for PDSCH.

[0165] Operation 6) above allows applying TBoMS suitable for higher SCS.

[0166] Action 7) Timeline parameters may be extended for SCSs greater than 960 kHz. For duration parameters, the value, range of values, or candidate values ​​for SCSs greater than 960 kHz may be determined as M times the 120 kHz SCS. For example, M may be the new SCS divided by 120. For example, for a 1920 kHz SCS, M = 1920 / 120 = 16.

[0167] For parameters relating to count numbers for SCSs above 960 kHz, such as maxNumberRxTxBeamSwitchDL, the minimum value supported for SCSs below 960 kHz may be applied.

K1 indicates the slot offset between the last slot of the PDSCH and the slot for transmitting the corresponding HARQ-ACK. K2 indicates the slot offset between the DCI and the scheduled PUSCH. The range of K0 may be 0 to 128×M. The range of K1 may be -1 to 128×M-1. The range of K2 may be 0 to 128×M.

[0179] 5) Δ (Delta): This parameter indicates the offset added to K2 for PUSCH scheduled in a Random Access Response (RAR) or fallback RAR. The value of this parameter may be M times the number of OFDM symbols for 120 kHz SCS.

[0180] 6) N ＰＤＳＣＨ This parameter indicates the PDSCH reception preparation time when cross-carrier scheduling is performed in different SCSs. The value of this parameter may be M times the number of OFDM symbols in the case of 120 kHz SCS.

[0181] 7) X This parameter indicates the minimum time gap between wake-up and SCell dormancy notification via DCI format 2_6. The value of this parameter may be M times the number of OFDM symbols in the case of 120 kHz SCS.

[0182] Operation 7) above allows applying timeline parameters suitable for higher SCS.

[0186] The above-described embodiment allows the terminal 20 to apply larger subcarrier spacing to the physical channel or signal.

[0187] That is, in a wireless communication system, it is possible to transmit and receive channels or signals that employ larger subcarrier spacing.

[0188] (Device Configuration) Next, a functional configuration example of the base station 10 and the terminal 20 that execute the processes and operations described above will be described. The base station 10 and the terminal 20 include functions for implementing the above-described embodiments. However, the base station 10 and the terminal 20 may each include only a part of the functions of the embodiments.

The names of the functional divisions and functional units may be any as long as they can execute the operations related to the embodiment of the present invention.

[0194] The transmitter 210 creates a transmission signal from transmission data and transmits the transmission signal wirelessly. The receiver 220 wirelessly receives various signals and acquires higher layer signals from the received physical layer signals. The receiver 220 also has a function of receiving NR-PSS, NR-SSS, NR-PBCH, DL / UL / SL control signals, and the like transmitted from the base station 10. For example, the transmitter 210 transmits a PSCCH (Physical Sidelink Control Channel), a PSSCH (Physical Sidelink Shared Channel), a PSDCH (Physical Sidelink Discovery Channel), a PSBCH (Physical Sidelink Broadcast Channel), and the like to another terminal 20 as D2D communication, and the receiver 220 receives the PSCCH, PSSCH, PSDCH, or PSBCH, and the like, from the other terminal 20.

The setting unit 230 also stores setting information that is set in advance. The content of the setting information is, for example, information related to communication to which a higher SCS is applied.

[0196] As described in the embodiments, the control unit 240 controls communication to which a higher SCS is applied. The signal transmission function in the control unit 240 may be included in the transmitting unit 210, and the signal reception function in the control unit 240 may be included in the receiving unit 220.

[0197] (Hardware Configuration) The block diagrams (FIGS. 20 and 21) used to explain the above embodiments show functional blocks. These functional blocks (components) are realized by any combination of at least one of hardware and software. Furthermore, the method for realizing each functional block is not particularly limited. That is, each functional block may be realized using a single device that is physically or logically coupled, or may be realized using two or more physically or logically separated devices that are directly or indirectly connected (for example, using wires, wirelessly, etc.) and these multiple devices. The functional block may be realized by combining software with the single device or the multiple devices.

[0198] Functions include, but are not limited to, judgment, determination, judgment, calculation, computation, processing, derivation, investigation, search, confirmation, reception, transmission, output, access, resolution, selection, selection, establishment, comparison, assumption, expectation, consideration, broadcasting, notifying, communicating, forwarding, configuring, reconfiguring, allocating, mapping, and assignment. For example, a functional block (component) that performs transmission is called a transmitting unit or transmitter. As mentioned above, there are no particular limitations on how these functions are implemented.

Fig. 22 is a diagram illustrating an example of the hardware configuration of the base station 10 and the terminal 20 according to an embodiment of the present disclosure. The base station 10 and the terminal 20 described above may be physically configured as a computer device including a processor 1001, a storage device 1002, an auxiliary storage device 1003, a communication device 1004, an input device 1005, an output device 1006, a bus 1007, etc.

[0200] In the following description, the term "apparatus" can be interpreted as a circuit, a device, a unit, etc. The hardware configuration of the base station 10 and the terminal 20 may be configured to include one or more of the apparatuses shown in the drawings, or may be configured to exclude some of the apparatuses.

[0220] (Summary of the embodiment) As described above, according to the embodiment of the present invention, there is provided a terminal having a control unit that assumes scheduling of a shared channel in block units consisting of multiple symbols or multiple slots in communications that apply subcarrier spacing exceeding a certain frequency, and a communication unit that receives the shared channel from a base station or transmits the shared channel to the base station in the communications.

[0221] With the above configuration, the terminal 20 can apply larger subcarrier spacing to physical channels or signals, i.e., can transmit and receive channels or signals to which larger subcarrier spacing is applied in a wireless communication system.

[0222] The control unit may determine the block based on the subcarrier spacing exceeding the certain frequency and a predefined reference subcarrier spacing. With this configuration, the terminal 20 can apply a larger subcarrier spacing to a physical channel or signal.

[0223] The control unit may perform frequency hopping of the uplink shared channel in units of the blocks, which allows the terminal 20 to apply a larger subcarrier spacing to the physical channel or signal.

[0224] The control unit may perform scaling with the granularity of the block unit to determine the position of a demodulation reference signal (DMRS). With this configuration, the terminal 20 can apply a larger subcarrier spacing to a physical channel or signal.

[0225] The controller may allocate a single code block or a single code word including multiple code blocks to multiple units of time, which allows the terminal 20 to apply larger subcarrier spacing to physical channels or signals.

[0226] Furthermore, according to an embodiment of the present invention, there is provided a communication method in which a terminal executes a procedure for assuming scheduling of a shared channel in block units consisting of multiple symbols or multiple slots in communication employing subcarrier spacing exceeding a certain frequency, and a procedure for receiving or transmitting the shared channel from a base station to the base station in the communication.

[0227] With the above configuration, the terminal 20 can apply a more appropriate waveform to a physical channel or signal depending on the communication environment, i.e., can determine the waveform to be applied in the wireless communication system.

[0232] In this specification, a specific operation described as being performed by the base station 10 may 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).

[0233] The information, signals, etc. 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.

[0234] Input and output information may be stored in a specific location (for example, memory) or may be managed using a management table. Input and output information may be overwritten, updated, or added to. Output information may be deleted. Input information may be transmitted to another device.

[0235] In the present disclosure, the determination may be made by a value represented by one bit (0 or 1), by a Boolean value (true or false), or by a comparison of numerical values ​​(e.g., comparison with a predetermined value).

[0237] Software, instructions, information, etc. may also be transmitted or received over a transmission medium. For example, if software is transmitted from a website, server, or other remote source using wired technologies (such as coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL)), and / or wireless technologies (such as infrared, microwave), then these wired and / or wireless technologies are included within the definition of transmission media.

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.

[0239] Note that terms described 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.

[0240] As used in this disclosure, the terms "system" and "network" are used interchangeably.

[0241] Furthermore, the information, parameters, etc. described in the present disclosure may be expressed using absolute values, relative values ​​from a predetermined value, or other corresponding information. For example, a radio resource may be indicated by an index.

[0242] 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.

[0243] In the present disclosure, terms such as "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," and "component carrier" may be used interchangeably. A base station may also be referred to by terms such as a macrocell, a small cell, a femtocell, and a picocell.

[0244] 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 partitioned into multiple smaller areas, and each smaller area can also be provided with communication services by a base station subsystem (e.g., a small indoor base station (RRH: Remote Radio Head)). The terms "cell" or "sector" refer to part or all of the coverage area of ​​a base station and / or base station subsystem that provides communication services within that coverage.

[0245] In the present disclosure, the base station transmitting information to a terminal may be interpreted as the base station instructing the terminal to control or operate based on the information.

[0246] In this disclosure, the terms "Mobile Station (MS)," "user terminal," "User Equipment (UE)," "terminal," and the like may be used interchangeably.

[0247] 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.

[0248] At least one of the base station and the mobile station may be referred to as 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 object, the mobile object itself, etc. The mobile object refers to a movable object, and may move at any speed. Naturally, this also includes cases where the mobile object is stationary. Examples of the mobile object include, but are not limited to, vehicles, transport vehicles, automobiles, motorcycles, bicycles, connected cars, excavators, bulldozers, wheel loaders, dump trucks, forklifts, trains, buses, handcars, rickshaws, ships and other watercraft, airplanes, rockets, satellites, drones (registered trademark), multicopters, quadcopters, balloons, and objects mounted thereon.

At least one of the base station and the mobile station may be a device that does 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.

[0249] 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 multiple terminals 20 (which may be called, for example, Device-to-Device (D2D) or Vehicle-to-Everything (V2X)). 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.

[0250] 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.

[0251] 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.

[0252] 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.

[0253] The reference signal may be abbreviated as RS (Reference Signal) or may be called a pilot depending on the applicable standard.

[0254] 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."

[0255] 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.

[0256] The "means" in the configuration of each of the above devices may be replaced with "part," "circuit," "device," etc.

[0257] When the terms "include," "including," and variations thereof are used in this disclosure, these terms are intended to be inclusive, similar to the term "comprising." Furthermore, when the term "or" is used in this disclosure, it is not intended to be an exclusive or.

[0258] 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.

[0259] Numerology may be communication parameters that apply to the transmission and / or 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, specific windowing operations performed by the transceiver in the time domain, etc.

[0260] 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.

[0261] 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.

[0262] 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.

[0263] 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.

[0264] 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.

[0265] 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.

[0266] 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.

[0267] 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.

[0268] 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 greater than or equal to 1 ms.

[0269] A resource block (RB) is a resource allocation unit in the time domain and the 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 the numerology, for example, 12. The number of subcarriers included in an RB may be determined based on the numerology.

[0270] 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.

[0271] 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, etc.

[0272] 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.

[0273] 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 BWP and numbered within the BWP.

[0274] The BWP may include a BWP for UL (UL BWP) and a BWP for DL ​​(DL BWP). One or more BWPs may be configured for a UE within one carrier.

[0275] At least one of the configured BWPs may be active, and the UE may not expect to transmit or receive a given signal / channel outside the active BWP. Note that the terms "cell," "carrier," etc. in this disclosure may be read as "BWP."

[0276] The above-described structures of radio frames, subframes, slots, minislots, symbols, etc. are merely examples, and various changes may be made to 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.

[0277] 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.

[0278] 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."

[0279] The aspects / embodiments described in this disclosure may be used alone, in combination, or switched depending on the implementation. Notification of predetermined information (e.g., notification that "X is true") is not limited to explicit notification, but may be implicit (e.g., not notifying the predetermined information).

[0280] 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.

Claims

1. A terminal having a control unit that assumes scheduling of a shared channel in block units consisting of multiple symbols or multiple slots in communications that apply subcarrier spacing exceeding a certain frequency, and a communication unit that receives the shared channel from a base station or transmits the shared channel to the base station in the communications.

2. The terminal according to claim 1, wherein the control unit determines the block based on the subcarrier spacing exceeding the certain frequency and a predefined reference subcarrier spacing.

3. The terminal according to claim 1, wherein the control unit performs frequency hopping of the uplink shared channel in units of the blocks.

4. The terminal according to claim 1, wherein the control unit performs scaling with granularity in block units to determine a position of a DMRS (Demodulation reference signal).

5. The terminal according to claim 1, wherein the control unit allocates a single code block or a single code word including multiple code blocks to multiple unit times.

6. A communications method in which a terminal executes the steps of: assuming scheduling of a shared channel in block units consisting of multiple symbols or multiple slots in communications employing subcarrier spacing exceeding a certain frequency; and receiving or transmitting the shared channel from a base station to the base station in the communications.
