Description

Technical Field

[0001] The present disclosure relates to a terminal performing wireless communication, and more particularly to a terminal performing multiplexing of uplink control information for an uplink shared channel. Background Art

[0002] The 3rd Generation Partnership Project (3GPP) has standardized the 5th generation mobile communication system (also referred to as 5G, New Radio (NR), or Next Generation (NG)), and in addition, has advanced the standardization of the next generation, referred to as Beyond 5G, 5G Evolution, or 6G.

[0003] In Release 15 of 3GPP, multiplexing of two or more uplink channels (Physical Uplink Control Channel (PUCCH) and Physical Uplink Shared Channel (PUSCH)) transmitted in the same time slot is supported.

[0004] In addition, in Release 17 of 3GPP, a case of supporting multiplexing of an Uplink Shared Channel (UL SCH) having a priority different from that of Uplink Control Information (UCI) has been negotiated (for example, Non-Patent Document 1).

[0008] Under this background, the inventors conducted in-depth research and found that in the multiplexing of UCI for UL SCH, when the available values of coefficients (e.g., β) for rate matching are within a predetermined range, the multiplexing of UCI for UL SCH cannot be appropriately performed.

[0030] Hereinafter, the embodiments will be described based on the drawings. In addition, the same or similar reference numerals are given to the same functions and structures, and their descriptions are appropriately omitted.

[0031] (1) Overall schematic structure of the wireless communication system

[0032] Figure 1 This is an overall schematic structure diagram of the wireless communication system 10 according to this embodiment. The wireless communication system 10 is a wireless communication system compliant with 5G New Radio (NR), and includes a next-generation radio access network 20 (NextGeneration-Radio Access Network 20, hereinafter referred to as NG-RAN 20) and a terminal 200 (hereinafter referred to as UE 200).

[0033] In addition, the wireless communication system 10 may also be a wireless communication system compliant with a mode called Beyond 5G, 5G Evolution or 6G.

[0034] NG-RAN 20 includes a radio base station 100A (hereinafter referred to as gNB 100A) and a radio base station 100B (hereinafter referred to as gNB 100B). In addition, the specific structure of the wireless communication system 10 including the number of gNBs and UEs is not limited to Figure 1 the example shown.

[0035] The NG-RAN 20 actually includes a plurality of NG-RAN nodes (Nodes), specifically, includes a plurality of gNBs (or ng-eNBs), and is connected to a 5G-compliant core network (5GC, not shown). In addition, the NG-RAN 20 and the 5GC can be simply referred to as the "network".

[0036] The gNBs 100A and 100B are 5G-compliant radio base stations and perform 5G-compliant wireless communication with the UE 200. The gNBs 100A, 100B, and the UE 200 can support Massive MIMO (Multiple-Input Multiple-Output) that generates a beam BM with higher directivity by controlling wireless signals transmitted from a plurality of antenna elements, carrier aggregation (CA) that bundles and uses a plurality of component carriers (CCs), and dual connectivity (DC) that enables simultaneous communication between the UE and two NG-RAN nodes respectively. The DC can include MR-DC (Multi-RAT Dual Connectivity) that uses MCG (Master Cell Group) and SCG (Secondary Cell Group). Examples of MR-DC include EN-DC (E-UTRA-NR Dual Connectivity), NE-DC (NR-EUTRA Dual Connectivity), and NR-DC (NR-NR Dual Connectivity), etc. Among them, it can be considered that the CCs (cells) used in CA constitute the same cell group. It can be considered that the MCG and the SCG constitute the same cell group.

[0037] In addition, the wireless communication system 10 supports multiple frequency ranges (FRs). Figure 2 Shows the frequency ranges used in the wireless communication system 10.

[0038] As Figure 2 shown, the wireless communication system 10 supports FR1 and FR2. The frequency bands of each FR are as described below.

[0039] · FR1: 410 MHz to 7.125 GHz

[0040] · FR2: 24.25 GHz to 52.6 GHz

[0041] In FR1, a sub-carrier spacing (SCS) of 15, 30, or 60 kHz can be used, and a bandwidth (BW) of 5 to 100 MHz is used. FR2 has a higher frequency than FR1. An SCS of 60 or 120 kHz (240 kHz can be included) can be used, and a bandwidth (BW) of 50 to 400 MHz is used.

[0042] In addition, the SCS can be interpreted as a numerology. The numerology is defined in 3GPP TS38.300 and corresponds to a sub-carrier spacing in the frequency domain.

[0043] In addition, the wireless communication system 10 also supports a frequency band higher than the frequency band of FR2. Specifically, the wireless communication system 10 supports a frequency band exceeding 52.6 GHz up to 114.25 GHz. Here, for ease of explanation, such a high-frequency band is referred to as "FR2x".

[0044] To solve this problem, in the case of using a band exceeding 52.6 GHz, cyclic prefix-orthogonal frequency division multiplexing (CP-OFDM) / discrete Fourier transform-spread (DFT-S-OFDM) with a larger sub-carrier spacing (SCS) can be applied.

[0045] Figure 3 An example of the structure of a radio frame, a sub-frame, and a time slot used in the wireless communication system 10 is shown.

[0046] As Figure 3 shown, 1 time slot consists of 14 symbols. The larger (wider) the SCS, the shorter the symbol period (and the time slot period). The SCS is not limited to Figure 3 the interval (frequency) shown. For example, 480 kHz, 960 kHz, etc. can be used.

[0047] In addition, the number of symbols constituting 1 time slot does not necessarily have to be 14 symbols (for example, 28, 56 symbols). In addition, the number of time slots per sub-frame can vary according to the SCS.

[0048] In addition, Figure 3 the time direction (t) shown can be referred to as the time domain, the symbol period, or the symbol time, etc. In addition, the frequency direction can also be referred to as the frequency domain, the resource block, the sub-carrier, the bandwidth part (BWP), etc.

[0049] (2) Functional block structure of the wireless communication system

[0050] Next, the functional block structure of the wireless communication system 10 will be described. Specifically, the functional block structure of the UE 200 will be described.

[0051] Figure 4 is the functional block structure diagram of the UE 200. As Figure 4 shown, the UE 200 includes a radio signal transceiver unit 210, an amplifier unit 220, a modulation / demodulation unit 230, a control signal / reference signal processing unit 240, an encoding / decoding unit 250, a data transceiver unit 260, and a control unit 270.

[0052] The radio signal transceiver unit 210 transmits and receives radio signals based on NR. The radio signal transceiver unit 210 supports Massive MIMO, CA that bundles multiple CCs, and DC that enables simultaneous communication between the UE and two NG-RAN nodes respectively.

[0053] The amplifier unit 220 is composed of a PA (Power Amplifier) / LNA (Low Noise Amplifier), etc. The amplifier unit 220 amplifies the signal output from the modulation / demodulation unit 230 to a predetermined power level. In addition, the amplifier unit 220 amplifies the RF signal output from the radio signal transceiver unit 210.

[0054] The modulation / demodulation unit 230 performs data modulation / demodulation, transmission power setting, resource block allocation, etc. for each predetermined communication destination (gNB100 or other gNBs). In the modulation / demodulation unit 230, Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM) / Discrete Fourier Transform-Spread (DFT-S-OFDM) can be applied. In addition, DFT-S-OFDM can be used not only for the uplink (UL) but also for the downlink (DL).

[0055] The control signal / reference signal processing unit 240 performs processing related to various control signals transmitted and received by the UE 200, and processing related to various reference signals transmitted and received by the UE 200.

[0056] Specifically, the control signal and reference signal processing unit 240 receives various control signals (e.g., control signals of the radio resource control layer (RRC)) transmitted from the gNB 100 via a predetermined control channel. In addition, the control signal and reference signal processing unit 240 transmits various control signals toward the gNB 100 via a predetermined control channel.

[0057] The control signal and reference signal processing unit 240 performs processing using reference signals (RS) such as demodulation reference signal (DMRS) and phase tracking reference signal (PTRS).

[0058] DMRS is a terminal-specific reference signal (pilot signal) known between the base station and the terminal for estimating the fading channel used in data demodulation. PTRS is a terminal-specific reference signal for the purpose of estimating phase noise, which becomes an issue in high frequency bands.

[0059] In addition, in addition to DMRS and PTRS, the reference signal also includes channel state information-reference signal (CSI-RS), sounding reference signal (SRS), and positioning reference signal (PRS) for location information, etc.

[0060] In addition, the channel includes a control channel and a data channel. The control channel includes PDCCH (Physical Downlink Control Channel), PUCCH (Physical Uplink Control Channel), RACH (Random Access Channel (random access channel), downlink control information (DCI) including a random access radio network temporary identifier (RA-RNTI)), and physical broadcast channel (PBCH), etc.

[0061] The data channel includes the PDSCH (Physical Downlink Shared Channel) and the PUSCH (Physical Uplink Shared Channel), etc. Data refers to the data transmitted via the data channel. The data channel can also be replaced by the shared channel.

[0062] In an embodiment, the control signal / reference signal processing unit 240 constitutes a communication unit that uses an uplink shared channel (UL SCH (Uplink Shared Channel)) multiplexed with uplink control information (UCI (Uplink Control Information)) to transmit an uplink signal. The UL SCH is a transport channel multiplexed on the PUSCH (Physical Uplink Shared Channel). The uplink signal transmitted via the UL SCH (PUSCH) may include UCI or may include data. The UCI may include an acknowledgement (HARQ-ACK) for one or more TBs. The UCI may include an SR (Scheduling Request) for requesting resource scheduling or may include CSI (Channel State Information) indicating the state of the channel. The UCI may be transmitted via the PUCCH or may be transmitted via the PUSCH.

[0063] The encoding / decoding unit 250 performs data segmentation / concatenation and channel encoding / decoding, etc. for each predetermined communication destination (gNB 100 or other gNBs).

[0064] Specifically, the encoding / decoding unit 250 segments the data output from the data transceiver unit 260 into a predetermined size and performs channel encoding on the segmented data. In addition, the encoding / decoding unit 250 decodes the data output from the modulation / demodulation unit 230 and concatenates the decoded data.

[0065] The data transceiver unit 260 performs the transmission and reception of protocol data units (PDUs) and service data units (SDUs). Specifically, the data transceiver unit 260 performs the assembly / disassembly of PDUs / SDUs in multiple layers (such as the media access control layer (MAC), the radio link control layer (RLC), and the packet data convergence protocol layer (PDCP), etc.). In addition, the data transceiver unit 260 performs error correction and retransmission control of data according to hybrid ARQ (Hybrid automatic repeat request).

[0066] The control unit 270 controls each functional block constituting the UE 200. In particular, in the embodiment, the control unit 270 constitutes a control unit that multiplexes UCI in the UL SCH. In the rate matching of UCI, the control unit 270 multiplies the number of bits constituting UCI by a coefficient (β). The control unit 270 applies an extended range including at least any one of a value smaller than a predetermined range and a value larger than the predetermined range as the range of β that can be taken. It can be considered that the predetermined range is the range defined in Release 16 of 3GPP. It can be considered that the extended range is the range defined in Release 17 of 3GPP.

[0067] (3) Rate matching

[0068] The rate matching will be described below. Specifically, the rate matching of UCI in the case of multiplexing UCI in the UL SCH will be described. Among them, as UCI, HARQ-ACK, CSI Part 1, and CSI Part 2 are exemplified. In addition, HARQ-ACK, CSI-Part 1, and CSI-Part 2 are executed separately.

[0069] As Figure 5 shown, by applying channel coding to the HARQ-ACK of the bit sequence having "X 0 , X 1 ,...", a bit sequence such as "C00, C01,..." is obtained. Rate matching is applied to such a bit sequence. The bit sequence (E UCI ) after rate matching can be represented by E UCI = N L × Q' ACK × Q m .

[0070] N L is the number of transmission layers of the PUSCH. Q m is the modulation condition of the PUSCH. For example, Q' ACK is represented by the following mathematical formula (TS38.212 V16.3.0 §6.3.2.4.1.1 "HARQ-ACK").

[0079] As Figure 6 shown, by applying channel coding to the CSI Part 1 (CSI part 1) of the bit sequence having "Y 0 , Y 1 ,...", a bit sequence such as "C00, C01,..." is obtained. Rate matching is applied to such a bit sequence. The bit sequence (E UCI ) after rate matching can be represented by E UCI = N L × Q’ CSI-part1 × Q m .

[0080] N L Is the number of transmission layers of the PUSCH. Q m Is the modulation condition of the PUSCH. For example, Q’ CSI-part1 Is represented by the following mathematical formula (TS38.212 V16.3.0 §6.3.2.4.1.2 "CSI part 1").

[0081] [Mathematical formula 2]

[0082]

[0083] Q CSI-1 Is the number of bits of CSI Part1.

[0084] L CSI-1 Is the number of bits of the CRC applied to CSI Part1.

[0085] is An example of a coefficient (β) multiplied by the number of bits constituting CSI Part1.

[0087] C UL-SCH Is the number of code blocks of UL-SCH for PUSCH transmission.

[0088] α is an example of a scaling factor multiplied by the radio resources available for UCI transmission (here ).

[0089] As Figure 7 shown, by applying channel coding to CSI Part 2 (CSI part 2) of a bit sequence with "Z 0 , Z 1 , ……", a bit sequence such as "C00, C01, ……" is obtained. Rate matching is applied to such a bit sequence. The rate-matched bit sequence (E UCI ) can be represented by E UCI = N L × Q’ CSI-part2 × Q m .

[0090] N L is the number of transmission layers of PUSCH. Q m is the modulation condition of PUSCH. For example, Q’ CSI-part2 is represented by the following formula (TS38.212 V16.3.0 §6.3.2.4.1.3 "CSI part 2").

[0091] [Formula 3]

[0092]

[0093] Q CSI-2 is the number of bits of CSI Part2.

[0094] L CSI-2 is the number of bits of CRC applied to CSI Part2.

[0095] is is an example of a coefficient (β) multiplied by the number of bits constituting CSI Part2.

[0096] Is the scheduled band region for PUSCH transmission, represented by the number of subcarriers.

[0097] C UL-SCH is the number of code blocks of UL-SCH for PUSCH transmission.

[0099] (4) Range of values that the coefficient (β) can take

[0100] The range of values that the coefficient (β) can take will be described below. Here, the coefficient (β) applied to HARQ-ACK will be taken as an example for illustration

[0101] (4.1) Predetermined range

[0102] As Figure 8 shown, regarding the predetermined range, the coefficient (β) shown in the right column is associated with the index shown in the left column (TS38.213 V16.3.0 §9.3 “UCI reporting in physical uplink shared channel”). For example, the minimum value of the values that the coefficient (β) can take in the predetermined range is “1.000”, and the maximum value of the values that the coefficient (β) can take in the predetermined range is “126.000”. Regarding indices of 16 or more, they are not associated with the coefficient (β) and can be used for future expansion (Reserved). As described above, the predetermined range is the range defined in Release 16 of 3GPP

[0103] (4.2) Example 1 of the extended range

[0104] As Figure 9 shown, regarding Example 1 of the extended range, similar to the predetermined range, the coefficient (β) shown in the right column is associated with the index shown in the left column. For example, Example 1 of the extended range includes values smaller than the minimum value “1.000” of the values that the coefficient (β) can take in the predetermined range (here “0.000”, “0.500”, “0.650”, “0.800”). In Example 1 of the extended range, indices such as Reserved in the predetermined range are used to define values smaller than the predetermined range

[0105] (4.3) Example 2 of the extended range

[0106] As Figure 10 shown, regarding Example 2 of the extended range, similar to the predetermined range, the coefficient (β) shown in the right column is associated with the index shown in the left column. For example, Example 2 of the extended range includes values smaller than the minimum value “1.000” of the values that the coefficient (β) can take in the predetermined range (here “0.000”, “0.500”, “0.650”, “0.800”). In Example 2 of the extended range, a new Table is defined in ascending order of the coefficient (β)

[0107] (4.4) Example 3 of the extended range

[0108] As Figure 11 shown, for Example 3 of the extended range, similar to the established range, the coefficient (β) shown in the right column is associated with the index shown in the left column. For example, Example 3 of the extended range includes a value (here "180.000") that is greater than the maximum value "126.000" that the coefficient (β) can take in the established range. In Example 3 of the extended range, an index such as Reserved is used in the established range to define a value greater than the established range.

[0109] (4.5) Example 4 of the extended range

[0110] As Figure 12 shown, for Example 4 of the extended range, similar to the established range, the coefficient (β) shown in the right column is associated with the index shown in the left column. For example, Example 4 of the extended range includes a value (here "180.000") that is greater than the maximum value "126.000" that the coefficient (β) can take in the established range. Example 4 of the extended range has the same structure as Example 3 of the extended range, but is different from Example 3 of the extended range in terms of the newly defined meaning of the Table.

[0111] (4.6) Example 5 of the extended range

[0112] As Figure 13 shown, for Example 5 of the extended range, similar to the established range, the coefficient (β) shown in the right column is associated with the index shown in the left column. For example, Example 5 of the extended range includes values (here "0.000", "0.500", "0.650", "0.800") that are less than the minimum value "1.000" that the coefficient (β) can take in the established range, and includes a value (here "180.000") that is greater than the maximum value "126.000" that the coefficient (β) can take in the established range. In Example 5 of the extended range, an index such as Reserved is used in the established range to define values less than the established range and values greater than the established range.

[0113] (4.7) Example 6 of the extended range

[0114] As Figure 14As shown, for Example 6 of the extended range, similar to the established range, the coefficient (β) shown in the right column is associated with the index shown in the left column. For example, Example 6 of the extended range includes values smaller than the minimum value "1.000" that the coefficient (β) can take in the established range (here, "0.000", "0.500", "0.650", "0.800"), and includes values larger than the maximum value "126.000" that the coefficient (β) can take in the established range (here, "180.000"). In Example 6 of the extended range, a new Table is defined in ascending order of the coefficient (β).

[0115] (5) Application Examples of the Extended Range

[0116] The following explains the application examples of the extended range. Here, the conditions required when applying the extended range are explained.

[0117] (5.1) Condition 1

[0118] Condition 1 is the case where there are no special requirements for the conditions required when applying the extended range. For example, when using an index such as Reserved in the established range to define any value (hereinafter referred to as the extended value of β) smaller than the established range and larger than the established range, the extended value of β can be specified by the existing index. For example, the extended ranges shown in Figure 9 、 Figure 11 and Figure 13 can be applied without special requirements.

[0119] As Figure 15As shown, the RRC message used in condition 1 may include an information element defined in Release 16 of 3GPP. The information element may include UCI-OnPUSCH or UCI-OnPUSCH-ForDCI-Fromat0-2-r16. UCI-OnPUSCH may include Dynamic or semiStatic as betaOffsets for a specified coefficient (β). UCI-OnPUSCH may include Scaling that specifies the above-mentioned scaling factor (α). UCI-OnPUSCH-ForDCI-Fromat0-2-r16 is an information element used when the format of the DCI is DCI Format 0_2. UCI-OnPUSCH-ForDCI-Fromat0-2-r16 may include Dynamic or semiStatic as betaOffsets for a specified coefficient (β). UCI-OnPUSCH-ForDCI-Fromat0-2-r16 may include Scaling that specifies the above-mentioned scaling factor (α). betaOffsets is the Figure 9 , Figure 11 and Figure 13 Information elements indexed as shown (TS38.331V16.2.0§6.3.2 "Radio Resource Control Information elements").

[0120] (5.2) Condition 2

[0121] Condition 2 is a case specified according to a radio resource control message (RRC message). In other words, UE 200 applies the extended range according to the RRC message.

[0122] For example, the RRC message may include an information element indicating whether the extended range is applied. When the RRC message includes an information element indicating that the extended range is applied, the extended range may be applied. When the RRC message does not include an information element indicating that the extended range is applied, or the RRC message includes an information element indicating that the extended range is not applied, the extended range may not be applied.

[0123] like Figure 16As shown, the RRC message used in condition 2 may include betaOffset-Table-r17 in addition to the information elements defined in 3GPP Release 16. betaOffset-Table-r17 may be included in UCI-OnPUSCH or in UCI-OnPUSCH-ForDCI-Fromat0-2-r16. When betaOffset-Table-r17 is enabled, the extended range can be applied.

[0124] As Figure 17 shown, the RRC message used in condition 2 may include UCI-OnPUSCH-r17 in addition to the information elements defined in 3GPP Release 16, or may also include UCI-OnPUSCH-ForDCI-Fromat0-2-r16-r17. Similar to UCI-OnPUSCH, UCI-OnPUSCH-r17 may include Dynamic or semiStatic as betaOffsets for specifying the coefficient (β). UCI-OnPUSCH-r17 may include Scaling for specifying the scaling factor (α). Similar to UCI-OnPUSCH-ForDCI-Fromat0-2-r16, UCI-OnPUSCH-ForDCI-Fromat0-2-r16-r17 may include Dynamic or semiStatic as betaOffsets for specifying the coefficient (β). UCI-OnPUSCH-ForDCI-Fromat0-2-r16-r17 may also include Scaling for specifying the scaling factor (α).

[0125] (5.3) Condition 3

[0126] Condition 3 is the case where UE 200 reports UECapability (UE capability) including information elements related to the application of the extended range. In other words, UE 200 applies the extended range according to the capability (UE Capability) of UE 200.

[0127] For example, the information element related to the application of the extended range may be an information element indicating that UE200 supports the multiplexing of UCI for uplink channels (UL-SCH, PUSCH) with different priorities from that of UCI. The information element related to the application of the extended range may also be an information element indicating that UE 200 supports the extended range.

[0128] (5.4) Condition 4

[0129] Condition 4 is the case where the format of the downlink control information (DCI) is a specific format. In other words, UE 200 applies the extended range according to the DCI. The specific format may be DCI Format 0_2.

[0130] In addition, Condition 4 can be combined with Condition 2 described above. For example, when betaOffset-Table-r17 included in UCI-OnPUSCH-ForDCI-Fromat0-2-r16 is enabled and the format of the DCI is DCI Format 0_2, the extended range can be applied. Or, when UCI-OnPUSCH-ForDCI-Fromat0-2-r16-r17 is included in the RRC message and the format of the DCI is DCI Format 0_2, the extended range can be applied.

[0131] (5.5) Condition 5

[0132] Condition 5 can be the case where the scaling factor (α) is above the first threshold or the case where the scaling factor (α) is below the second threshold. In other words, UE 200 applies the extended range according to the value of the scaling factor (α).

[0133] For example, the first threshold can be the minimum value (“1.000”) of the values that the coefficient (β) can take in a given range. When the value of α is above the minimum value, an extended range including values smaller than the given range can be applied. The second threshold can be the maximum value (“126.000”) of the values that the coefficient (β) can take in a given range. When the value of α is below the maximum value, an extended range including values larger than the given range can be applied.

[0134] (5.6) Condition 6

[0135] Condition 6 can be the case where the priority of the uplink control information (UCI) is different from the priority of the uplink shared channel (UL-SCH, PUSCH). In other words, UE 200 can apply the extended range when the priority of the UCI is different from the priority of the UL-SCH.

[0136] For example, when the priority of the UCI is low and the priority of the UL-SCH is high, an extended range including values smaller than the given range can be applied. In this case, it can be that the higher-priority UCI has been multiplexed in the PUSCH (UL-SCH). When the priority of the UCI is high and the priority of the UL-SCH is low, an extended range including values larger than the given range can be applied.

[0137] In addition, when the priority of UCI is the same as that of UL-SCH, the UE 200 may apply the established range. However, when the priority of UCI is the same as that of UL-SCH, the UE 200 may apply the extended range. The case where the priority of UCI is the same as that of UL-SCH may include the case where the priorities of both UCI and UL-SCH are low, and may also include the case where the priorities of both UCI and UL-SCH are high.

[0138] (6) Example of operation

[0139] The following describes an example of the operation of the embodiment. The following mainly describes the multiplexing of UCI for UL-SCH (PUSCH).

[0140] As Figure 18 shown, in step S10, the UE 200 sends a message including UE Capability to the NG-RAN 20. The UE Capability may include an information element related to the application of the extended range (the above condition 3).

[0141] In step S11, the UE100 receives an RRC message from the NG-RAN 20. The RRC message may include an information element indicating whether to apply the extended range (the above conditions 1 and 2).

[0142] In step S12, the UE 200 receives one or more DCIs from the NG-RAN 20 via PDCCH. The format of the DCI may be DCI Format 0_2 (the above condition 4).

[0143] In step S13, the UE 200 uses the UL-SCH (PUSCH) multiplexed with UCI to send an uplink signal. In this case, the UE 200 may apply the extended range as the range in which the coefficient (β) can be taken according to at least any one of the above conditions 1 to 6.

[0144] (7) Function and effect

[0145] In the embodiment, as the range in which the coefficient (β) used in rate matching can be taken, the UE 200 applies an extended range including at least any one value of a value smaller than the established range and a value larger than the established range ( Figures 9 to 14 ). According to this structure, the multiplexing of uplink control information (UCI) for the uplink shared channel (UL-SCH, PUSCH) can be appropriately performed. In particular, this structure is useful when the priority of UCI is different from that of UL-SCH.

[0146] [Other embodiments]

[0147] As described above, the content of the present invention has been described along with the embodiments. However, the present invention is not limited to these descriptions and can be variously modified and improved, which is obvious to those skilled in the art.

[0148] In the above disclosure, HARQ-ACK has been mainly described. However, the above disclosure is not limited thereto. The UCI multiplexed in the UL-SCH may also include CSI Part 1 and may further include CSI Part 2. In this case, the minimum value of the value that the coefficient (β) can take within a given range may be "1.125". The maximum value of the value that the coefficient (β) can take within a given range may be "20.00" (TS38.213 V16.3.0 §9.3 "UCI reporting in physical uplink shared channel"). Therefore, the extended range of the coefficient (β) related to CSI Part 1 and CSI Part 2 may include values smaller than "1.125" and may also include values larger than "20.00".

[0149] Although not particularly mentioned in the above disclosure, the given range may be a range used when the priority of the uplink control information (UCI) is the same as the priority of the uplink shared channel (UL-SCH, PUSCH). Such a range may be referred to as the first range. It may also be a range used when the priority of the uplink control information (UCI) is different from the priority of the uplink shared channel (UL-SCH, PUSCH). Such a range may be referred to as the second range.

[0150] Although not particularly mentioned in the above disclosure, the priority can be determined as follows. For example, the priority of HARQ-ACK may be higher than the priority of SR. The priority related to URLLC (Ultra Reliable and Low Latency Communications) may be higher than the priority related to eMBB (enhanced Mobile BroadBand).

[0151] In the description of the above embodiments, the block diagrams used Figure 4) shows blocks in terms of functions. These functional blocks (structural parts) are implemented by any combination of at least one of hardware and software. In addition, there is no particular limitation on the implementation method of each functional block. That is, each functional block can be implemented using a single device physically or logically combined, or two or more physically or logically separated devices can be directly or indirectly (e.g., using wired, wireless, etc.) connected and these multiple devices can be used for implementation. The functional block can also be implemented by combining software with the above-mentioned single device or the above-mentioned multiple devices.

[0152] Functionally, it has judgment, decision-making, determination, calculation, computation, processing, derivation, investigation, search, confirmation, reception, transmission, output, access, solution, selection, selection, establishment, comparison, assumption, expectation, regarded as, broadcasting, notifying, communicating, forwarding, configuring, reconfiguring, allocating (mapping), assigning, etc., but is not limited to these. For example, a functional block (structural part) that makes transmission function is called a transmitting unit or a transmitter. In short, as described above, there is no particular limitation on the implementation method.

[0153] In addition, the above-mentioned UE 200 (this device) can also function as a computer that processes the wireless communication method of the present disclosure. Figure 19 is a diagram showing an example of the hardware structure of this device.

[0155] Each functional block of this device (refer to Figure 4 ) is implemented by any hardware element of this computer device or a combination of these hardware elements.

[0156] In addition, the functions in the device are implemented by the following method: a predetermined software (program) is read into hardware such as the processor 1001 and the memory 1002, so that the processor 1001 performs operations and controls at least one of the communication of the communication device 1004 or the reading and writing of data in the memory 1002 and the storage 1003.

[0157] The processor 1001, for example, operates the operating system to control the entire computer. The processor 1001 may also be composed of a central processing unit (CPU) including an interface with peripheral devices, a control device, an arithmetic device, registers, etc.

[0158] In addition, the processor 1001 reads a program (program code), a software module, or data, etc. from at least one of the storage 1003 and the communication device 1004 into the memory 1002, and performs various processes accordingly. As the program, a program that causes a computer to execute at least a part of the operations described in the above embodiments is used. In addition, regarding the above various processes, although it has been described that the above various processes are executed by one processor 1001, the above various processes may also be executed simultaneously or sequentially by two or more processors 1001. The processor 1001 may also be installed on one or more chips. In addition, the program may also be sent from a network via a telecommunication line.

[0159] The memory 1002 is a computer-readable recording medium and may, for example, be composed of at least one of a read-only memory (ROM), an erasable programmable ROM (EPROM), an electrically erasable programmable ROM (EEPROM), a random access memory (RAM), etc. The memory 1002 may also be referred to as a register, a cache, a main memory (main storage device), etc. The memory 1002 can store a program (program code), a software module, etc. that can execute the method according to an embodiment of the present disclosure.

The above-mentioned recording medium can be, for example, other appropriate media such as a database or a server that includes at least one of the memory 1002 and the memory 1003.

[0161] The communication device 1004 is hardware (a transceiver device) for communicating between computers via at least one of a wired network and a wireless network. For example, it can also be referred to as a network device, a network controller, a network card, a communication module, etc.

[0162] The communication device 1004 can be configured to include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc., for example, to implement at least one of frequency division duplex (FDD) and time division duplex (TDD).

[0163] The input device 1005 is an input device that accepts external input (e.g., a keyboard, a mouse, a microphone, a switch, a button, a sensor, etc.). The output device 1006 is an output device that performs external output (e.g., a display, a speaker, an LED light, etc.). In addition, the input device 1005 and the output device 1006 can also be integrally formed (e.g., a touch panel).

[0164] In addition, each device such as the processor 1001 and the memory 1002 is connected by a bus 1007 for communicating information. The bus 1007 can be composed of a single bus or can be composed of different buses for each device.

[0165] In addition, the device may be configured to include hardware such as a microprocessor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a programmable logic device (PLD), a field programmable gate array (FPGA), etc., and a part or all of each functional block may also be implemented by such hardware. For example, the processor 1001 may also be installed using at least one of these hardware components.

[0166] In addition, the notification of information is not limited to the forms / embodiments described in the present disclosure, and other methods may also be used. For example, the notification of information may be implemented through physical layer signaling (e.g., downlink control information (DCI), uplink control information (UCI)), high layer signaling (e.g., RRC signaling, medium access control (MAC) signaling, broadcast information (master information block (MIB), system information block (SIB))), other signals, or a combination thereof. In addition, RRC signaling may also be referred to as an RRC message. For example, it may also be an RRC connection setup message, an RRC connection reconfiguration message, etc.

[0167] Each form / embodiment described in the present disclosure can also be applied to at least one of Long Term Evolution (LTE), LTE-Advanced (LTE-A), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), Future Radio Access (FRA), New Radio (NR), W-CDMA (registered trademark), GSM (registered trademark), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, UWB (Ultra-WideBand), Bluetooth (registered trademark), systems using other appropriate systems, and next-generation systems extended therefrom. In addition, multiple systems (for example, a combination of at least one of LTE and LTE-A and 5G, etc.) can be combined and applied.

[0168] For the processing procedures, timings, flows, etc. of each form / embodiment described in the present disclosure, the order can be changed without contradiction. For example, for the methods described in the present disclosure, the illustrated order indicates the elements of various steps, but is not limited to the specific order indicated.

[0169] Specific actions performed by the base station in the present disclosure may be performed by its upper node under certain circumstances. In a network composed of one or more network nodes having a base station, it is obvious that various actions performed for communicating with a terminal can be performed by at least one of the base station and other network nodes other than the base station (for example, MME or S-GW, etc. are considered, but are not limited to these). In the above, the case where there is one other network node other than the base station is illustrated, but the other network nodes may also be a combination of multiple other network nodes (for example, MME and S-GW).

[0170] Information, signals (such as information) can be output from a higher layer (or a lower layer) to a lower layer (or a higher layer). It can also be input or output via multiple network nodes.

[0171] The input or output information can be stored in a specific location (e.g., memory), or can be managed using a management table. The input or output information can be rewritten, updated, or appended. The output information can also be deleted. The input information can also be sent to other devices.

[0172] The determination can be made by a value represented by 1 bit (0 or 1), can be made by a Boolean value (true or false), or can also be made by a numerical comparison (e.g., comparison with a predetermined value).

[0173] Each form / embodiment described in this disclosure can be used alone, can be used in combination, or can also be switched according to the execution. In addition, the notification of predetermined information is not limited to being explicit (e.g., notification of "it is X"), and can also be implicit (e.g., without notification of the predetermined information).

[0174] For software, regardless of whether it is called software, firmware, middleware, microcode, hardware description language, or by other names, it should be broadly interpreted to mean commands, command sets, code, code segments, program code, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, processes, functions, etc.

[0175] In addition, software, commands, information, etc. can be transmitted and received via a transmission medium. For example, when using at least one of wired technologies (coaxial cables, fiber optic cables, twisted pairs, Digital Subscriber Line (DSL), etc.) and wireless technologies (infrared rays, microwaves, etc.) to send software from a web page, server, or other remote source, at least one of these wired and wireless technologies is included in the definition of the transmission medium.

[0176] The information, signals, etc. described in this disclosure can also be represented using any one of a variety of different technologies. For example, the data, commands, instructions, information, signals, bits, symbols, chips, etc. that may be involved in the above description as a whole can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, optical fields or photons, or any combination of these.

[0177] In addition, the terms described in this disclosure and the terms required to understand 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 also be a signal (signaling). In addition, a signal may also be a message. In addition, a component carrier (CC) may be referred to as a carrier frequency, a cell, a frequency carrier, etc.

[0178] The terms "system" and "network" used in this disclosure may be used interchangeably.

[0179] In addition, the information, parameters, etc. described in this disclosure may be represented by absolute values, may be represented by relative values with respect to a predetermined value, or may be represented by other corresponding information. For example, radio resources may also be indicated by an index.

[0180] The names used for the above parameters are non-restrictive in any aspect. Furthermore, the mathematical expressions, etc. using these parameters are sometimes different from the content explicitly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by appropriate names, and thus the various names assigned to these various channels and information elements are non-restrictive in any aspect.

[0181] In this disclosure, the terms "Base Station (BS)", "radio base station", "fixed station", "NodeB", "eNodeB (eNB)", "gNodeB (gNB)", "access point", "transmission point", "reception point", "transmission / reception point", "cell", "sector", "cell group", "carrier", "component carrier", etc. may be used interchangeably. Sometimes, a base station is also referred to as a macro cell, a small cell, a femto cell, a pico cell, etc.

[0182] A base station can accommodate one or more (e.g., three) cells (also referred to as sectors). When a base station accommodates multiple cells, the entire coverage area of the base station can be divided 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 (Remote Radio Head (RRH))).

[0183] The term "cell" or "sector" refers to a part or the whole of the coverage area of at least one of a base station and a base station subsystem that provides communication services within that coverage range.

[0184] In the present disclosure, terms such as "Mobile Station (MS)", "user terminal", "User Equipment (UE)", and "terminal" can be used interchangeably.

[0185] For a mobile station, those skilled in the art sometimes also refer to it using the following terms: subscriber station, mobile unit, subscriber unit, radio 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 appropriate terms.

[0186] At least one of the base station and the mobile station may also be referred to as a transmitting device, a receiving device, a communication device, etc. In addition, at least one of the base station and the mobile station may be a device mounted on a moving body, the moving body itself, etc. The moving body may be a vehicle (e.g., a car, an airplane, etc.), a moving body that moves in an unmanned manner (e.g., a drone, a self-driving car, etc.), or a robot (humanoid or non-humanoid). In addition, at least one of the base station and the mobile station also includes a device that does not necessarily move during a communication operation. For example, at least one of the base station and the mobile station may be an Internet of Things (IoT) device such as a sensor.

[0187] In addition, the base station in the present disclosure may also be replaced with a mobile station (user terminal, the same hereinafter). For example, regarding a structure in which the communication between the base station and the mobile station is replaced with the communication between multiple mobile stations (e.g., it may also be referred to as Device-to-Device (D2D), Vehicle-to-Everything (V2X), etc.), various forms / embodiments of the present disclosure can also be applied. In this case, it may also be configured such that the mobile station has the functions of the base station. In addition, terms such as "uplink" and "downlink" can also be replaced with terms corresponding to inter-terminal communication (e.g., "side"). For example, an uplink channel, a downlink channel, etc. can also be replaced with a side channel.

[0188] Similarly, the mobile station in the present disclosure can be replaced with a base station. In this case, it may be configured such that the base station has the functions of the mobile station.

[0189] A radio frame may be composed of one or more frames in the time domain. In the time domain, each of the one or more frames may be referred to as a subframe.

[0190] A subframe can be composed of one or more time slots in the time domain. The subframe can have a fixed time length (e.g., 1 ms) independent of the numerology.

[0191] The numerology can be communication parameters applied to at least one of transmission and reception of a certain signal or channel. For example, the numerology can represent at least one of subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame structure, specific filtering processing performed by the transceiver in the frequency domain, specific windowing processing performed by the transceiver in the time domain, etc.

[0192] A time slot can be composed of one or more symbols (orthogonal frequency division multiplexing (OFDM) symbols, single carrier frequency division multiple access (SC-FDMA) symbols, etc.) in the time domain. The time slot can be a time unit based on the numerology.

[0193] A time slot can contain multiple mini-slots. Each mini-slot can be composed of one or more symbols in the time domain. In addition, a mini-slot can also be referred to as a sub-slot. A mini-slot can be composed of a smaller number of symbols than a time slot. The PDSCH (or PUSCH) transmitted in a time unit larger than a mini-slot can be called PDSCH (or PUSCH) mapping type A. The PDSCH (or PUSCH) transmitted using a mini-slot can be called PDSCH (or PUSCH) mapping type B.

[0194] The radio frame, subframe, time slot, mini-slot, and symbol all represent time units when transmitting signals. The radio frame, subframe, time slot, mini-slot, and symbol can be respectively referred to by corresponding other names.

[0195] For example, 1 subframe can be called a transmission time interval (TTI), multiple consecutive subframes can also be called a TTI, 1 time slot or 1 mini-slot can also be called a TTI. That is, at least one of the subframe and the TTI can be the subframe (1 ms) in the existing LTE, or a period shorter than 1 ms (e.g., 1 - 13 symbols), or a period longer than 1 ms. In addition, the unit representing the TTI can be not a subframe, but a time slot, a mini-slot, etc.

[0196] Here, the TTI refers to, for example, the minimum time unit for scheduling in wireless communication. For example, in the LTE system, the base station performs scheduling to allocate radio resources (such as the bandwidth and transmission power that can be used in each user terminal) to each user terminal in units of TTI. Additionally, the definition of the TTI is not limited to this.

[0197] The TTI can be the transmission time unit for data packets (transport blocks), code blocks, codewords, etc. after channel coding, or can also be the processing unit for scheduling, link adaptation, etc. Additionally, when the TTI is given, the actual time interval (e.g., the number of symbols) to which the transport block, code block, codeword, etc. are mapped can be shorter than the TTI.

[0198] Additionally, when 1 time slot or 1 mini time slot is referred to as the TTI, one or more TTIs (i.e., one or more time slots or one or more mini time slots) can constitute the minimum time unit for scheduling. Furthermore, the number of time slots (mini time slots) that constitute the minimum time unit for this scheduling can be controlled.

[0199] The TTI with a time length of 1 ms is also referred to as the normal TTI (TTI in LTE Rel.8 - 12), normal TTI, long TTI, normal subframe, long subframe, time slot, etc. The TTI shorter than the normal TTI can be called the shortened TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, mini time slot, sub - time slot, time slot, etc.

[0200] Additionally, for the long TTI (e.g., normal TTI, subframe, etc.), it can be replaced with a TTI having a time length exceeding 1 ms, and for the short TTI (e.g., shortened TTI, etc.), it can be replaced with a TTI having a TTI length less than that of the long TTI and having a TTI length of 1 ms or more.

[0201] The resource block (RB) is the resource allocation unit in the time domain and the frequency domain. In the frequency domain, it can contain one or more consecutive subcarriers. The number of subcarriers contained in the RB can be the same regardless of the parameter set, for example, it can be 12. The number of subcarriers contained in the RB can also be determined according to the parameter set.

[0202] Furthermore, the time domain of the RB can contain one or more symbols and can be the length of 1 time slot, 1 mini time slot, 1 subframe, or 1 TTI. 1 TTI, 1 subframe, etc. can each be composed of one or more resource blocks.

[0203] In addition, one or more RBs may be referred to as Physical Resource Blocks (PRBs), Sub-Carrier Groups (SCGs), Resource Element Groups (REGs), PRB pairs, RB pairs, etc.

[0204] Furthermore, a resource block may be composed of one or more resource elements (REs). For example, 1 RE may be a radio resource region of 1 sub-carrier and 1 symbol.

[0205] A Bandwidth Part (BWP) (which may also be referred to as a partial bandwidth, etc.) represents a subset of consecutive common resource blocks (common RBs) used for a certain parameter set in a certain carrier. Here, the common RBs can be determined by the indices of the RBs based on the common reference point of the carrier. PRBs are defined in a certain BWP and numbered within that BWP.

[0206] A BWP may include a BWP for UL (UL BWP) and a BWP for DL (DL BWP). One or more BWPs may be set for a UE within one carrier.

[0207] At least one of the set BWPs may be active, and it may not be assumed that the UE transmits and receives a predetermined signal / channel outside the active BWP. In addition, "cell", "carrier", etc. in the present disclosure may be replaced by "BWP".

[0208] The structures of the above-mentioned radio frames, sub-frames, time slots, mini time slots, symbols, etc. are merely illustrative. For example, the number of sub-frames included in a radio frame, the number of time slots per sub-frame or radio frame, the number of mini time slots included in a time slot, the number of symbols and RBs included in a time slot or mini time slot, the number of sub-carriers included in an RB, and the number of symbols, symbol length, Cyclic Prefix (CP) length, etc. within a TTI may be changed in various ways.

[0209] Terms such as "connected" and "coupled" and all variations of these terms are intended to represent all direct or indirect connections or couplings between two or more elements, which may include cases where there is one or more intermediate elements between the two elements that are "connected" or "coupled" to each other. The coupling or connection between elements can be a physical coupling or connection, a logical coupling or connection, or a combination of these. For example, "Access" can be used to replace "connected". In the context of the present disclosure, for two elements, it can be considered that they are "connected" or "coupled" to each other by using at least one of one or more electric wires, cables, and printed electrical connections, and as some non-limiting and non-inclusive examples, by using electromagnetic energy having wavelengths in the wireless frequency domain, microwave region, and optical (including both visible and invisible) regions, etc.

[0210] The reference signal can be abbreviated as Reference Signal (RS), or can be called Pilot according to the applied standard.

[0211] The description "in accordance with" used in the present disclosure does not mean "only in accordance with" unless otherwise clearly stated. In other words, the meaning of the description "in accordance with" is both "only in accordance with" and "at least in accordance with".

[0212] The "unit" in the structure of each of the above devices can be replaced with "section", "circuit", "device", etc.

[0213] Any reference to elements using terms such as "first", "second", etc. used in the present disclosure does not entirely limit the quantity and order of these elements. These terms are used in the present disclosure as a simple method to distinguish between two or more elements. Therefore, the reference to the first and second elements does not mean that only two elements can be adopted here or that the first element must precede the second element in any form.

[0214] When terms such as "include", "including" and their variations are used in the present disclosure, these terms mean inclusive in the same way as the term "comprising". And the term "or" used in the present disclosure does not mean exclusive or.

[0215] In the present disclosure, for example, when articles are added through translation such as a, an, and the in English, the present disclosure also includes cases where the nouns following these articles are in the plural form.

[0216] The terms "determining" and "deciding" as used in this disclosure sometimes also include situations involving a variety of actions. For example, "determining" and "deciding" can include regarding matters that have been judged, calculated, computed, processed, derived, investigated, looked up (e.g., looked up in a table, database, or other data structure), or ascertained as matters that have been "determined" or "decided". In addition, "determining" and "deciding" can include regarding matters that have been received (e.g., received information), transmitted (e.g., transmitted information), input, output, accessed (e.g., accessed data in memory), etc. as matters that have been "determined" or "decided". Further, "determining" and "deciding" can include regarding matters that have been resolved, selected, chosen, established, compared, etc. as matters that have been "determined" or "decided". That is, "determining" and "deciding" can include matters that have "determined" or "decided" any action. In addition, "determining (deciding)" can also be replaced by "assuming", "expecting", "considering", etc.

[0217] In this disclosure, the term "A and B are different" can also mean "A and B are mutually different". Additionally, this term can also mean "A and B are each different from C". Terms such as "separating" and "combining" can be interpreted in the same way as "different".

[0218] As described above, this disclosure has been explained in detail. However, for those skilled in the art, it should be clear that this disclosure is not limited to the embodiments described in this disclosure. This disclosure can be implemented in the form of modifications and changes without departing from the gist and scope of this disclosure determined by the claims. Therefore, the purpose of the description of this disclosure is for illustrative purposes and has no restrictive meaning for this disclosure.
