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, the specification of an offset value for scheduling downlink data or uplink data continues to be studied from LTE. [Prior art documents] [Non-patent literature]

[0005] [Non-Patent Document 1] 3GPP TS 38.300 V16.6.0(2021-06) [Non-patent document 2] 3GPP TS 38.306 V16.5.0(2021-06) Summary of the Invention [Problem to be solved by the invention]

[0006] The offset value specifications for scheduling downlink or uplink data under consideration in NR need to be expanded because the range is too narrow to accommodate the large subcarrier spacing supported in higher frequency bands, such as those from 52.6 GHz to 71 GHz.

[0007] The present invention has been made in view of the above points, and has as its object to apply an offset value for scheduling downlink data or uplink data to a high frequency band. [Means for solving the problem]

[0008] According to the disclosed technology, a receiver receives a signal including an offset value setting extended for a frequency band equal to or greater than a reference value from a base station, and a slot of downlink data received from the base station and a slot of downlink data transmitted to the base station based on the offset value setting extended for a frequency band equal to or greater than a reference value. Uplink Data and a control unit that sets a slot for the reference value, wherein the control unit is capable of setting the minimum value of the offset value extended for frequency bands equal to or greater than the reference value to a value greater than the minimum value of the offset value for frequency bands less than the reference value. [Effects of the Invention]

[0009] According to the disclosed technology, a technology is provided that enables an offset value for scheduling downlink data or uplink data to be applied to a high frequency band. [Brief explanation of the drawings]

[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 in 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. Furthermore, CORESET#0 / Type0-PDCCH included in the MIB for SSBs of 120 kHz SCS, 480 kHz SCS, and 960 kHz SCS may be supported. Furthermore, 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}. Furthermore, SSB-CORESET multiplexing pattern 1 may be prioritized.

[0024] 3 is a diagram explaining offset values for scheduling. K0 is an offset value between a PDCCH to be scheduled and a PDSCH to be scheduled. K1 is an offset value between a PDSCH and a PUCCH including a corresponding HARQ-ACK. K2 is an offset value between a PDCCH to be scheduled and a PUSCH to be scheduled. Each of the offset values K0, K1, and K2 is defined as a slot-by-slot value.

[0025] Conventionally, K0 is set as the value of the "PDSCH-TimeDomainResourceAllocation" item. The value of K0 ranges from 0 to 32 in slot units.

[0026] K1 is set as the value of the "DL-DataToUL-ACK" item and is selected from the values set via the DCI instruction. The value of K1 ranges from 0 to 15 in slot units.

[0027] K2 is set as the value of the "PUSCH-TimeDomainResourceAllocation" item. The value of K2 ranges from 0 to 32 in slot units.

[0028] In NR, it has been agreed that in the FR2-2 frequency band, the values of K0, K1, and K2 are each set as a numerical value in slot units.

[0029] Figure 4 shows an example of a specified value for the PDSCH decoding time. N1 is the specified value for the PDSCH decoding time and is specified in symbol units. Specified values for N1 for subcarrier spacings of 120 kHz, 480 kHz, and 960 kHz have been agreed upon.

[0030] Figure 5 shows an example of a specified value for the PUSCH preparation time. N2 is the specified value for the PUSCH preparation time and is specified in symbol units. Specified values for N2 for subcarrier spacings of 120 kHz, 480 kHz, and 960 kHz have been agreed upon.

[0031] Figure 6 shows an example of a specified value for the HARQ-ACK multiplexing timeline. N3 is a specified value for the HARQ-ACK multiplexing timeline and is specified in symbol units. Specified values for N3 with subcarrier spacings of 120 kHz, 480 kHz, and 960 kHz have been agreed upon.

[0032] In addition, k_offset is supported in non-terrestrial networks (NTNs) in NR Release 17, and the following specifications have already been agreed upon: · k_offset is applied to K1 and K2. Note that when k_offset is applied, the offset values of K1 and K2 are K1+k_offset and K2+k_offset, respectively. · k_offset is set by RRC. · k_offset is a value that can be updated by RRC and / or MAC.

[0033] Furthermore, cross-slot scheduling for power saving is specified as an extension of NR Release 16. A minimum applicable value of K0 / CSI-RS trigger offset in a downlink BWP (Bandwidth Part) and a minimum applicable value of K2 in an uplink BWP are configured in the terminal 20.

[0034] Figure 7 shows an example of a specified value for power saving. The upper layer parameter minimumSchedulingOffset can indicate up to two values of BWP. DCI format 0_1 or 1_1 can indicate the value to be applied to the minimum applicable value from the two values.

[0035] Fig. 8 is a diagram showing an example of a TDRA table. For example, if K0=2 is the minimum applicable value, index values 4 to 7 shown in Fig. 8 are applicable.

[0036] Terminal 20 also assumes that K0 / K2 / CSI-RS trigger offsets smaller than the smallest applicable scheduling offset are not scheduled or triggered in DCI, with some exceptions, e.g., PDSCH transmissions scheduled in SI-RNTI or RA-RNTI.

[0037] 9 is a diagram showing an example of RRC parameters for power saving. The range of the minimum scheduling offset is defined as an RRC parameter.

[0038] FIG. 10 is a diagram illustrating an example of signaling of terminal capabilities notified for power saving. The terminal 20 can signal its recommended minimum values K0 / K2 via terminal capability signaling (optional, non-basic).

[0039] The traditional range of values for K0 / K1 / K2 (especially K0) may be too narrow considering the processing timeline, even when k_offset is applied.

[0040] For example, the k_offset discussed in NTN may not take K0 into account. In addition, in the case of multi-PDSCH or PUSCH scheduling, K0 or K2 is set for each PDSCH or PUSCH, but may not be consecutive. In particular, when the subcarrier spacing is greater than 120 kHz (e.g., at least one of 480 and 960 kHz), it may be too narrow.

[0041] (Outline of this embodiment) Therefore, in this embodiment, a method for realizing a wide range of scheduling offset values to accommodate the large subcarrier spacing (for example, larger than 120 kHz) supported in the high frequency band from 52.6 GHz to 71 GHz is shown.

[0042] Specifically, in a first embodiment, an offset value k_offset is introduced into the scheduling offset values K0 / K1 / K2. In a second embodiment, the range of the scheduling offset values K0 / K1 / K2 is extended to a value greater than 32, for example. Note that 52.6 GHz is an example of a reference value indicating the high frequency band of FR2-2. This embodiment may also be applied to a high frequency band of 71 GHz or higher.

[0043] Example 1 In this embodiment, an example is shown in which an offset value k_offset is introduced into the scheduling offset values K0 / K1 / K2.

[0044] 11 is a diagram illustrating a scheduling offset value according to the first embodiment. The offset value k_offset is added to each of the scheduling offset values K0, K1, and K2 and then applied.

[0045] <Option 1> A method for setting the offset value k_offset may be specified.

[0046] <Option 1-1> The offset value k_offset may be set by the base station 10 in the RRC.

[0047] <Option 1-2> The offset value k_offset may be predefined in the specifications.

[0048] <Option 1-2-1> The fixed value defined in the specification may be defined based on the processing capabilities of the terminal (e.g., N1 / N2).

[0049] <Option 1-2-2> The fixed value defined in the specification may be a fixed value according to the terminal processing capability of each of N1 / N2 (for example, capability 1 or 2).

[0050] <Options 1-3> The offset value k_offset may be set by the base station 10 in the MAC-CE.

[0051] <Options 1-4> The offset value k_offset may be specified by the base station 10 in the DCI.

[0052] <Options 1-5> The offset value k_offset may be specified by the terminal 20 via terminal capability signaling.

[0053] <Option 2> In addition, a method for updating the offset value k_offset may be defined.

[0054] <Option 2-1> The offset value k_offset may be updated by the base station 10 via RRC configuration.

[0055] <Option 2-2> The offset value k_offset may be updated by the base station 10 via MAC-CE.

[0056] <Option 2-3> The offset value k_offset may be updated by the base station 10 via DCI.

[0057] The above options may be combined, for example, one may be selected via MAC-CE or DCI from candidate values configured via RRC or MAC-CE.

[0058] <Option 3> A relationship between the proposed offset value and the k_offset value of K1 / K2 may be specified, provided that the introduced offset value is different from the k_offset value.

[0059] <Option 3-1> A single uniform value may be applied, in which case the introduced offset value may be the k_offset value.

[0060] <Option 3-2> Different values may be applied between K0 / K1 / K2.

[0061] <Option 3-2-1> The k_offset value of K1 / K2 may be common to the k_offset value of at least one of K0 and K1.

[0062] According to this embodiment, the conventional value range of K0 is fully utilized, allowing flexible PDSCH allocation.

[0063] Example 2 In this embodiment, an example in which the range of the scheduling offset values K0 / K1 / K2 is expanded is shown.

[0064] Example 2-1 The range of the scheduling offset values K0 / K1 / K2 may be extended to values greater than 32 (for example, 64).

[0065] <Option 1> Conditions under which this embodiment is applied may be specified.

[0066] <Option 1-1> This embodiment may be applied under the condition that the device operates in the FR2-2 high frequency band, ie, in the range of 52.6-71 GHz.

[0067] <Option 1-2> This embodiment may be applied provided that the subcarrier spacing is at least either 480 or 960 kHz.

[0068] <Options 1-3> This embodiment may be applied on the condition that multi-PDSCH / PUSCH scheduling is configured. For example, the terminal 20 may determine that the condition is met when the configured TDRA table includes one or more rows including multiple SLIVs.

[0069] According to this embodiment, more flexible scheduling of multi-PDSCH / PUSCH by DCI is realized.

[0070] Also, a larger minimum value for K0 / K2 than conventional values (for power saving purposes) may be required.

[0071] 12 is a diagram showing an example of a range of offset values for conventional scheduling. Conventionally, the range of the minimum scheduling offset is specified as an RRC parameter, and a value between 0 and 16 can be selected as the minimum value.

[0072] Figure 13 shows an example of conventional terminal capability signaling. It may be necessary to increase the terminal's recommended value via terminal capability signaling. For example, conventionally, subcarrier spacing is limited to 120 kHz or less.

[0073] Therefore, in the following, a third embodiment will be described in which the minimum value of K0 / K2 can be selected from larger values to save power. Also, a fourth embodiment will be described in which the minimum value of K0 / K2 as a recommended value for a terminal can be selected from larger values.

[0074] Example 3 In this embodiment, an example is shown in which the minimum value of K0 / K2 can be selected from larger values in order to save power.

[0075] <Plan 1> A larger minimum value of K0 / K2 may be supported.

[0076] <Option 1> Methods may be defined to support larger values.

[0077] <Option 1-1> 14 is a diagram illustrating an example of a range of a scheduling offset value according to Example 3. As illustrated in FIG. 14, a value exceeding 16 (e.g., 32) may be supported for the maximum number of slots set as the minimum value of the scheduling offset (K0 / K2).

[0078] <Option 2> When operating under specific conditions, the values of maxK0-SchedulingOffset(-r16) / maxK2-SchedulingOffset(-r16) may be reinterpreted.

[0079] The specific condition may depend on the subcarrier spacing. For example, if the set subcarrier spacing is greater than X, then maxK0-SchedulingOffset(-r16) and / or maxK2-SchedulingOffset(-r16) are reinterpreted as Y times the originally defined value (i.e., 16).

[0080] The specific conditions may also depend on the operating band or frequency range. For example, when operating with a subcarrier spacing greater than 120 kHz and / or when operating in the 52.6-71 GHz frequency range, maxK0-SchedulingOffset(-r16) and / or maxK2-SchedulingOffset(-r16) are reinterpreted as Y times their originally defined value (i.e., 16).

[0081] According to Scheme 1, the terminal 20 can extend the microsleep time, leading to more efficient power consumption.

[0082] <Plan 2> Conventional value ranges and k_offset may be combined.

[0083] That is, at least one of the values set in MinSchedulingOffsetK0 and MinSchedulingOffsetK2 is reinterpreted as follows.

[0084] The value set in MinSchedulingOffsetK0 + k_offset / the value set in MinSchedulingOffsetK2 + k_offset

[0085] <Option 1> It is also possible to specify the value on which k_offset is obtained.

[0086] <Option 1-1> The k_offset may be obtained from that proposed in the first embodiment.

[0087] <Option 1-2> k_offset may be obtained from a value dedicated to power saving.

[0088] <Option 2> You may also specify where k_offset is set.

[0089] <Option 2-1> The k_offset may be configured by the RRC.

[0090] <Option 2-2> The k_offset may be set in the MAC-CE.

[0091] <Option 2-3> The k_offset may be indicated in the DCI.

[0092] <Option 2-4> A combination of options 2-1, 2-2 and 2-3 is also possible. For example, candidate values may be configured in RRC and the actual values may be indicated via MAC-CE or DCI.

[0093] Example 4 In this embodiment, an example is shown in which the range of the terminal recommended minimum value K0 / K2 is expanded.

[0094] <Plan 1> Larger subcarrier spacing values may be defined by conventional terminal capability signaling (FG19-4a).

[0095] 15 is a diagram illustrating an example of terminal capabilities according to Proposal 1 of Example 4. A range of the minimum value K0 / K2 recommended by the terminal at a subcarrier spacing of 480 kHz or 960 kHz is newly added to the conventional terminal capability signaling (FG19-4a).

[0096] <Plan 2> Support for larger subcarrier spacing may be extended with the same value as conventional subcarrier spacing.

[0097] 16 is a diagram illustrating an example of terminal capabilities according to Proposal 2 of Example 4. 480 kHz or 960 kHz is added to the subcarrier spacing corresponding to the range of the minimum value K0 / K2 value recommended for conventional terminals in the conventional terminal capability signaling (FG19-4a).

[0098] <Plan 3> A new FG may be defined to support assistance information reporting for terminals operating in the 52.6-71 GHz band.

[0099] 17 is a diagram illustrating an example of terminal capabilities according to Proposal 3 of Example 4. In the new terminal capability signaling, a range of the minimum value K0 / K2 recommended by the terminal at a subcarrier spacing of 480 kHz or 960 kHz is set.

[0100] The above-mentioned setting values are merely examples, and other values may be used.

[0101] The above-described embodiments may be applied to terminals operating at 52.6-71 GHz (ie, FR2-2).

[0102] Additionally, the above-described embodiments may be applied to terminals operating at subcarrier spacings of 480 and 960 kHz.

[0103] (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. The base station 10 and the terminal 20 include functions for executing the above-described embodiments. However, the base station 10 and the terminal 20 may each include only the functions proposed in any of the embodiments.

The transmitting unit 210 and the receiving unit 220 may also be called a transmitter and a receiver, respectively.

[0110] The terminal or base station of this embodiment may be configured as a terminal or base station shown in each of the following items. Also, the following communication method may be implemented.

[0111] <Configuration of this embodiment> (Section 1) a receiving unit that receives from a base station a signal indicating a setting of a scheduling offset value extended to communications using a frequency band equal to or greater than a reference value; a control unit that assumes that downlink data transmitted from the base station or uplink data transmitted to the base station is scheduled by applying the scheduling offset value extended to the frequency band, Terminal. (Section 2) The control unit assumes a value obtained by adding an offset value extended to a communication using a frequency band equal to or greater than the reference value to a scheduling offset value corresponding to the communication using a frequency band less than the reference value, as the scheduling offset value extended to the frequency band. 1. The terminal described in paragraph 1. (Section 3) The control unit assumes a scheduling offset value in a range extended from a scheduling offset value corresponding to communication using a frequency band less than the reference value as the scheduling offset value extended to the frequency band. 1. The terminal described in paragraph 1. (Section 4) the control unit is capable of selecting a minimum value of the scheduling offset value to be used for communication using a frequency band equal to or greater than the reference value from values greater than a minimum value corresponding to communication using a frequency band less than the reference value. A terminal according to any one of paragraphs 1 to 3. (Section 5) a transmitting unit that transmits to a terminal a signal indicating a setting of a scheduling offset value extended to communications using a frequency band equal to or greater than a reference value; a control unit that schedules downlink data to be transmitted to the terminal or uplink data received from the terminal by applying the scheduling offset value extended to the frequency band, Base station. (Section 6) receiving, from a base station, a signal indicating a setting of a scheduling offset value extended to communications using a frequency band equal to or greater than a reference value; and assuming that downlink data transmitted from the base station or uplink data transmitted to the base station is scheduled by applying the scheduling offset value extended to the frequency band.

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.

[0140] 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).

[0141] 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.

[0142] 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 sent to another device.

[0143] In the present disclosure, the determination may be made based on a value represented by one bit (0 or 1), a Boolean value (true or false), or a numerical comparison (e.g., comparison with a predetermined value).

[0145] 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.

[0147] 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.

[0148] As used in this disclosure, the terms "system" and "network" are used interchangeably.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] In this disclosure, the terms "Mobile Station (MS)," "user terminal," "User Equipment (UE)," "terminal," etc. may be used interchangeably.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] The reference signal may be abbreviated as RS (Reference Signal) or may be called a pilot depending on the applicable standard.

[0161] 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."

[0162] 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.

[0163] The "means" in the configuration of each of the above devices may be replaced with "part," "circuit," "device," etc.

[0164] 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.

[0165] 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.

[0166] 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.

[0167] 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.

[0168] 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.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] 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.

[0173] 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.

[0174] 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.

[0175] 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.

[0176] 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.

[0177] 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.

[0178] 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.

[0179] 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.

[0180] 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.

[0181] 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.

[0182] 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."

[0183] 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.

[0184] 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.

[0185] 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."

[0186] 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).

[0187] 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.
