Description

[Technical Field]

[0001] The present disclosure relates to a terminal that performs wireless communication, and in particular to a terminal that multiplexes uplink control information onto an uplink shared channel. [Background technology]

[0002] The 3rd Generation Partnership Project (3GPP) has developed specifications for the 5th generation mobile communication system (5G, also known as New Radio (NR) or Next Generation (NG)), and is also developing specifications for the next generation, known as Beyond 5G, 5G Evolution, or 6G.

[0003] 3GPP Release 15 supports multiplexing of two or more uplink channels (a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH)) transmitted in the same slot.

[0004] Furthermore, in Release 17 of 3GPP, it was agreed to support multiplexing into an UL SCH (Uplink Shared Channel) having a priority different from the priority of UCI (Uplink Control Information) (for example, Non-Patent Document 1). [Prior art documents] [Non-patent literature]

[0005] [Non-Patent Document 1] "Enhanced Industrial Internet of Things (IoT) and ultra-reliable and low latency communication", RP-201310, 3GPP TSG RAN Meeting #86e, 3GPP, July 2020 Summary of the Invention

[0006] Under such circumstances, the inventors have conducted extensive research and found that when multiplexing UCI onto UL SCH, if the possible values ​​of a coefficient (e.g., β) used for rate matching remain within a predetermined range, multiplexing UCI onto UL SCH cannot be performed appropriately.

[0007] Therefore, the following disclosure has been made in consideration of such circumstances, and aims to provide a terminal that can appropriately multiplex uplink control information onto an uplink shared channel.

[0008] One aspect of the present disclosure is a terminal including: a control unit that multiplexes uplink control information onto an uplink shared channel; and a communication unit that transmits an uplink signal using the uplink shared channel on which the uplink control information is multiplexed, wherein the control unit multiplies a number of bits constituting the uplink control information by a coefficient in rate matching of the uplink control information; and the control unit applies, as a range of the coefficient, a specific range according to a combination of a priority of the uplink control information and a priority of the uplink shared channel.

[0010] Hereinafter, embodiments will be described with reference to the drawings. Note that the same or similar reference numerals are used to designate the same functions or configurations, and descriptions thereof will be omitted as appropriate.

[0011] [Embodiment] (1) Overall configuration of wireless communication system 1 is a schematic diagram of an overall configuration of a wireless communication system 10 according to an embodiment. The wireless communication system 10 is a wireless communication system conforming to 5G New Radio (NR), and includes a Next Generation-Radio Access Network 20 (hereinafter, NG-RAN 20) and a terminal 200 (hereinafter, UE 200).

[0012] The wireless communication system 10 may be a wireless communication system conforming to a system called Beyond 5G, 5G Evolution, or 6G.

[0013] The NG-RAN 20 includes a radio base station 100A (hereinafter, gNB100A) and a radio base station 100B (hereinafter, gNB100B). Note that the specific configuration of the radio communication system 10, including the number of gNBs and UEs, is not limited to the example shown in FIG. 1.

[0014] The NG-RAN 20 actually includes multiple NG-RAN nodes, specifically, gNBs (or ng-eNBs), and is connected to a 5G-compliant core network (5GC, not shown). The NG-RAN 20 and the 5GC may also be simply referred to as a "network."

[0015] The gNB100A and gNB100B are radio base stations conforming to 5G and perform 5G radio communication with the UE200. The gNB100A, gNB100B, and UE200 are capable of supporting Massive MIMO (Multiple-Input Multiple-Output), which generates a more directional beam (BM) by controlling radio signals transmitted from multiple antenna elements; Carrier Aggregation (CA), which aggregates and uses multiple component carriers (CCs); and Dual Connectivity (DC), which simultaneously communicates between the UE and two NG-RAN nodes. DC may include Multi-RAT Dual Connectivity (MR-DC), which uses a Master Cell Group (MCG) and a Secondary Cell Group (SCG). Examples of MR-DC include E-UTRA-NR Dual Connectivity (EN-DC), NR-EUTRA Dual Connectivity (NE-DC), and NR-NR Dual Connectivity (NR-DC). Here, CCs (cells) used in CA may be considered to constitute the same cell group. The MCG and SCG may be considered to constitute the same cell group.

[0016] The wireless communication system 10 also supports a plurality of frequency ranges (FR).

[0017] 2, the wireless communication system 10 supports FR1 and FR2. The frequency bands of each FR are as follows:

[0018] FR1: 410 MHz to 7.125 GHz FR2: 24.25 GHz~52.6 GHz FR1 may use a Sub-Carrier Spacing (SCS) of 15, 30, or 60 kHz and a bandwidth (BW) of 5 to 100 MHz. FR2 is a higher frequency than FR1, and may use an SCS of 60 or 120 kHz (including 240 kHz) and a bandwidth (BW) of 50 to 400 MHz.

[0019] Note that SCS may be interpreted as numerology, which is defined in 3GPP TS38.300 and corresponds to one subcarrier spacing in the frequency domain.

[0020] Furthermore, the wireless communication system 10 also supports frequency bands higher than the FR2 frequency band. Specifically, the wireless communication system 10 supports frequency bands exceeding 52.6 GHz up to 114.25 GHz. For convenience, such high frequency bands may be referred to as "FR2x."

[0021] To solve the problem of increased phase noise in high frequency bands, when using bands above 52.6 GHz, Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM) / Discrete Fourier Transform - Spread (DFT-S-OFDM) with larger Sub-Carrier Spacing (SCS) may be applied.

[0022] FIG. 3 shows an example of the configuration of a radio frame, a subframe, and a slot used in the radio communication system 10. In FIG.

[0023] As shown in Figure 3, one slot consists of 14 symbols, and the larger (wider) the SCS, the shorter the symbol period (and slot period). The SCS is not limited to the interval (frequency) shown in Figure 3. For example, 480 kHz, 960 kHz, etc. may be used.

[0024] Also, the number of symbols constituting one slot does not necessarily have to be 14 (for example, 28 or 56 symbols). Furthermore, the number of slots per subframe may differ depending on the SCS.

[0025] 3 may be called a time domain, a symbol period, a symbol time, etc. The frequency direction may be called a frequency domain, a resource block, a subcarrier, a BWP (Bandwidth Part), etc.

[0026] (2) Functional block configuration of wireless communication system Next, a description will be given of the functional block configuration of the wireless communication system 10. Specifically, a description will be given of the functional block configuration of the UE 200.

[0027] Fig. 4 is a functional block diagram of UE 200. As shown in Fig. 4, UE 200 includes radio signal transmitting / receiving unit 210, amplifier unit 220, modem unit 230, control signal / reference signal processing unit 240, encoding / decoding unit 250, data transmitting / receiving unit 260, and control unit 270.

[0028] The radio signal transmitting / receiving unit 210 transmits and receives radio signals conforming to NR. The radio signal transmitting / receiving unit 210 supports Massive MIMO, CA that uses a bundle of multiple CCs, and DC that simultaneously communicates between a UE and two NG-RAN nodes.

[0029] The amplifier unit 220 is configured by 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. The amplifier unit 220 also amplifies the RF signal output from the radio signal transmission / reception unit 210.

[0030] The modem unit 230 performs data modulation / demodulation, transmission power setting, resource block allocation, etc. for each predetermined communication destination (gNB 100 or another gNB). The modem unit 230 may apply Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM) / Discrete Fourier Transform - Spread (DFT-S-OFDM). Furthermore, DFT-S-OFDM may be used not only for the uplink (UL) but also for the downlink (DL).

[0031] The control signal / reference signal processor 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 .

[0032] Specifically, the control signal / reference signal processor 240 receives various control signals, for example, control signals of a radio resource control layer (RRC), transmitted via a predetermined control channel from the gNB 100. The control signal / reference signal processor 240 also transmits various control signals to the gNB 100 via a predetermined control channel.

[0033] The control signal / reference signal processor 240 performs processing using reference signals (RS) such as a Demodulation Reference Signal (DMRS) and a Phase Tracking Reference Signal (PTRS).

[0034] DMRS is a reference signal (pilot signal) known between the base station and the terminal for estimating the fading channel used for data demodulation. PTRS is a terminal-specific reference signal for estimating phase noise, which is an issue in high frequency bands.

[0035] In addition to the DMRS and PTRS, the reference signals may include a Channel State Information-Reference Signal (CSI-RS), a Sounding Reference Signal (SRS), and a Positioning Reference Signal (PRS) for position information.

[0036] The channels include control channels and data channels, such as a PDCCH (Physical Downlink Control Channel), a PUCCH (Physical Uplink Control Channel), a RACH (Random Access Channel), Downlink Control Information (DCI) including a Random Access Radio Network Temporary Identifier (RA-RNTI), and a Physical Broadcast Channel (PBCH).

[0037] Furthermore, the data channel includes a PDSCH (Physical Downlink Shared Channel) and a PUSCH (Physical Uplink Shared Channel). Data refers to data transmitted via the data channel. The data channel may be interpreted as a shared channel.

[0038] In an embodiment, the control signal and reference signal processor 240 configures a communication unit that transmits an uplink signal using an uplink shared channel (UL SCH (Uplink Shared Channel)) multiplexed with uplink control information (UCI (Uplink Control Information)). The UL SCH is a transport channel multiplexed with a PUSCH (Physical Uplink Shared Channel). The uplink signal transmitted via the UL SCH (PUSCH) may include UCI and may also include data. The UCI may include an acknowledgement (HARQ-ACK) for one or more TBs. The UCI may include a scheduling request (SR) requesting resource scheduling, or may include channel state information (CSI) indicating the channel state. The UCI may be transmitted via a PUCCH or via a PUSCH.

[0039] The encoding / decoding unit 250 performs data division / concatenation and channel coding / decoding for each predetermined communication destination (gNB100 or another gNB).

[0040] Specifically, the encoding / decoding unit 250 divides the data output from the data transmitting / receiving unit 260 into pieces of a predetermined size, performs channel coding on the divided data, decodes the data output from the modem unit 230, and concatenates the decoded data.

[0041] The data transmitter / receiver 260 transmits and receives Protocol Data Units (PDUs) and Service Data Units (SDUs). Specifically, the data transmitter / receiver 260 assembles and disassembles PDUs / SDUs in multiple layers (such as a Medium Access Control layer (MAC), a Radio Link Control layer (RLC), and a Packet Data Convergence Protocol layer (PDCP)). The data transmitter / receiver 260 also performs data error correction and retransmission control based on Hybrid Automatic Repeat Request (Hybrid ARQ).

[0042] 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 onto the UL SCH. In rate matching of the UCI, the control unit 270 multiplies the number of bits constituting the UCI by a coefficient (β). The control unit 270 applies a specific range of the coefficient (β) according to a combination of the priority of the UCI and the priority of the UL SCH. The predetermined range may be considered to be the range defined in Release 16 of 3GPP. The specific range may be considered to be the range defined in Release 17 of 3GPP.

[0043] (3) Rate Matching Rate matching will be described below. Specifically, rate matching of UCI in the case where UCI is multiplexed onto UL SCH will be described. Here, HARQ-ACK, CSI Part 1, and CSI Part 2 will be exemplified as UCI. Note that HARQ-ACK, CSI-Part 1, and CSI-Part 2 are executed separately.

[0044] As shown in FIG. 5, a bit sequence of "C00, C01, ..." is obtained by applying channel coding to a HARQ-ACK having a bit sequence of "X0, X1, ...". Rate matching is applied to such a bit sequence. The bit sequence after rate matching (E UCI ) is EUCI =N L ×Q' ACK ×Q m It may be represented by:

[0045] N L is the number of PUSCH transmission layers. Q m is the modulation condition of PUSCH. For example, Q' ACK is expressed by the following formula (TS38.212 V16.3.0 §6.3.2.4.1.1 “HARQ-ACK”).

[0046]

number

[0047] As shown in FIG. 6, a bit sequence of "C00, C01, ..." is obtained by applying channel coding to CSI Part 1 having a bit sequence of "Y0, Y1, ...". Rate matching is applied to such a bit sequence. The bit sequence after rate matching (E UCI ) is E UCI =N L ×Q' CSI-part1 ×Q m It may be represented by:

[0048] N L is the number of PUSCH transmission layers. Q m is the modulation condition of PUSCH. For example, Q' CSI-part1 is expressed by the following formula (TS38.212 V16.3.0 §6.3.2.4.1.2 “CSI part 1”).

[0049]

number

[0050] As shown in FIG. 7, a bit sequence of "C00, C01, ..." is obtained by applying channel coding to CSI Part 2 having a bit sequence of "Z0, Z1, ...". Rate matching is applied to such a bit sequence. The bit sequence after rate matching (E UCI ) is E UCI =N L ×Q' CSI-part2 ×Q m It may be represented by:

[0051] N L is the number of PUSCH transmission layers. Q m is the modulation condition of PUSCH. For example, Q' CSI-part2 is expressed by the following formula (TS38.212 V16.3.0 §6.3.2.4.1.3 “CSI part 2”).

[0052]

number

[0053] (4) Possible range of coefficient (β) The range that the coefficient (β) can take will be explained below, taking the coefficient (β) applied to HARQ-ACK as an example.

[0054] (4.1) Predefined range As shown in FIG. 8, for the predetermined range, the coefficient (β) shown in the right column corresponds to 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 that the coefficient (β) can take in the predetermined range is “1.000”, and the maximum value that the coefficient (β) can take in the predetermined range is “126.000”. For indexes 16 and above, no coefficient (β) is associated and they can be used for future expansion (Reserved). As mentioned above, the predetermined range is the range defined in 3GPP Release 16.

[0055] (4.2) Specific Range As described above, the specific range is determined according to the combination of the priority of the UCI and the priority of the UL SCH. Here, HARQ-ACK is used as an example of the UCI. However, the UCI may be CSI part 1, CSI part 2, or SR.

[0056] The combination of the UCI priority and the UL SCH (here, PUSCH) priority may include (i) a combination of an LP (Low Priority) HARQ-ACK and an LP PUSCH, (ii) a combination of an LP HARQ-ACK and an HP (High Priority) PUSCH, (iii) a combination of an HP HARQ-ACK and an LP PUSCH, and (iv) a combination of an HP HARQ-ACK and an LP PUSCH.

[0057] (i) An index associated with a specific range according to a combination of an LP (Low Priority) HARQ-ACK and an LP PUSCH may be referred to as betaOffsetACK-Index1. (ii) An index associated with a specific range according to a combination of an LP HARQ-ACK and an HP (High Priority) PUSCH may be referred to as betaOffsetACK-Index2. (iii) An index associated with a specific range according to a combination of an HP HARQ-ACK and an LP PUSCH may be referred to as betaOffsetACK-Index3. (iv) An index associated with a specific range according to a combination of an HP HARQ-ACK and an LP PUSCH may be referred to as betaOffsetACK-Index4.

[0058] As a setting configuration of the specific range (betaOffsetACK-Index1 to betaOffsetACK-Index4) according to the combination of the UCI priority and the UL SCH priority, the setting configuration shown in FIG. 9 may be adopted.

[0059] A specific range corresponding to a combination of HARQ-ACK and PUSCH having the same priority may be excluded. In other words, the specified range shown in FIG. 8 may be used as the range of the coefficient (β) corresponding to a combination of HARQ-ACK and PUSCH having the same priority.

[0060] (5) Examples of application of the extended range An example of application of the extended range will be described below, along with the conditions required for applying the extended range.

[0061] (5.1) Condition 1 Condition 1 is that the extension range is specified based on a radio resource control message (RRC message). In other words, the UE 200 applies the extension range based on the RRC message.

[0062] Condition 1 is that the range is specified based on a radio resource control message (RRC message). In other words, the UE 200 applies the specific range based on the RRC message.

[0063] For example, the RRC message may include an information element indicating whether the specific range applies. If the RRC message includes an information element indicating that the specific range applies, the specific range may be applied. If the RRC message does not include an information element indicating that the specific range applies, or if the RRC message includes an information element indicating that the specific range does not apply, the specific range may not be applied.

[0064] (5.1.1) Example 1 As shown in FIG. 10, UCI-OnPUSCH may include Dynamic or semiStatic as betaOffsets specifying the coefficient (β). UCI-OnPUSCH may include Dynamic-Prio or semiStatic-Prio as betaOffsets specifying the coefficient (β) included in a specific range. UCI-OnPUSCH-ForDCI-Fromat0-2-r16 is an information element used when the DCI format is DCI Format 0_2. UCI-OnPUSCH-ForDCI-Fromat0-2-r16 may include DynamicForDCI-Fromat0-2-r16 or semiStaticForDCI-Fromat0-2-r16 as betaOffsets specifying the coefficient (β). UCI-OnPUSCH-ForDCI-Fromat0-2-r16 may include oneBit-prio-r17 or twoBit-prio-r17 included in DynamicForDCI-Fromat0-2-r16 as betaOffsets that specify a coefficient (β) included in a specific range, or may include semiStaticForDCI-Fromat0-2-Prio-r17.

[0065] (5.1.2) Example 2 As shown in FIG. 11 , UCI-OnPUSCH may include Dynamic or semiStatic as betaOffsets that specifies the coefficient (β). UCI-OnPUSCH includes betaOffsets-Prio-r17 that specifies the coefficient (β) included in a specific range. betaOffsets-Prio-r17 may include Dynamic or semiStatic. UCI-OnPUSCH-ForDCI-Fromat0-2-r16 is an information element used when the DCI format is DCI Format 0_2. UCI-OnPUSCH-ForDCI-Fromat0-2-r16 may include DynamicForDCI-Fromat0-2-r16 or semiStaticForDCI-Fromat0-2-r16 as betaOffsets that specifies the coefficient (β). UCI-OnPUSCH-ForDCI-Fromat0-2-r16 may include UCI-OnPUSCH-ForDCI-Fromat0-2-Prio-r17 as an information element for specifying a coefficient (β) falling within a specific range. UCI-OnPUSCH-ForDCI-Fromat0-2-Prio-r17 may include DynamicForDCI-Fromat0-2-Prio-r17 or semiStaticForDCI-Fromat0-2-Prio-r17 as betaOffsets for specifying a coefficient (β) falling within a specific range. DynamicForDCI-Fromat0-2-Prio-r17 may include oneBit-prio-r17 or twoBit-prio-r17.

[0066] (5.2) Condition 2 Condition 2 is that UE Capability including information elements related to application of the specific range is reported from UE 200. In other words, UE 200 applies the specific range based on the capability of UE 200 (UE Capability).

[0067] For example, the information element regarding application of a specific range may be an information element indicating that the UE 200 supports multiplexing of UCI to uplink channels (UL-SCH, PUSCH) having a priority different from the priority of the UCI. The information element regarding application of a specific range may be an information element indicating that the UE 200 supports the specific range.

[0068] (5.3) Condition 3 Condition 3 is that the format of the downlink control information (DCI) is a specific format. In other words, the UE 200 applies a specific range based on the DCI. The specific format may be DCI Format 0_2.

[0069] Condition 3 may be combined with the above-mentioned condition 1. For example, the specific range may be applied when betaOffset-Table-r17 included in UCI-OnPUSCH-ForDCI-Fromat0-2-r16 is enabled and the DCI format is DCI Format 0_2. Alternatively, the specific range may be applied when UCI-OnPUSCH-ForDCI-Fromat0-2-r16-r17 is included in the RRC message and the DCI format is DCI Format 0_2.

[0070] (5.4) Condition 4 Condition 4 may be that the priority of the uplink control information (UCI) is different from the priority of the uplink shared channel (UL-SCH, PUSCH). In other words, the UE 200 may apply the specific range when the priority of the UCI is different from the priority of the UL-SCH.

[0071] For example, when the priority of UCI is low and the priority of UL-SCH is high, a specific range including values ​​smaller than the predetermined range may be applied. In such a case, UCI with high priority may already be multiplexed onto the PUSCH (UL-SCH). When the priority of UCI is high and the priority of UL-SCH is low, a specific range including values ​​larger than the predetermined range may be applied.

[0072] Note that UE 200 may apply a predetermined range when the priority of UCI is the same as the priority of UL-SCH. However, UE 200 may apply a specific range when the priority of UCI is the same as the priority of UL-SCH. The case where the priority of UCI is the same as the priority of UL-SCH may include a case where both the priority of UCI and UL-SCH are low, or may include a case where both the priority of UCI and UL-SCH are high.

[0073] (6) Example of operation An example of the operation of the embodiment will be described below, focusing mainly on multiplexing UCI onto UL-SCH (PUSCH).

[0074] 12, in step S10, the UE 200 transmits a message including UE Capability to the NG-RAN 20. The UE Capability may include an information element regarding application of a specific range (condition 2 above).

[0075] In step S11, the UE 100 receives an RRC message from the NG-RAN 20. The RRC message may include an information element indicating whether or not the specific range applies (condition 1 above).

[0076] In step S12, the UE 200 receives one or more DCIs via the PDCCH from the NG-RAN 20. The format of the DCI may be DCI Format 0_2 (condition 4 above).

[0077] In step S13, UE 200 transmits an uplink signal using UL-SCH (PUSCH) multiplexed with UCI. In such a case, UE 200 may apply a specific range as a possible range for coefficient (β) based on at least one of conditions 1 to 4 described above.

[0078] (7) Actions and Effects In the embodiment, the UE 200 applies a specific range according to a combination of the priority of the UCI and the priority of the UL SCH as a possible range of the coefficient (β) used in rate matching. This configuration makes it possible to appropriately multiplex the uplink control information (UCI) onto the uplink shared channel (UL-SCH, PUSCH). This configuration is particularly useful in a case where the priority of the UCI is different from the priority of the UL-SCH.

[0079] [Change Example 1] Modification 1 of the embodiment will be described below, with differences from the embodiment being described below.

[0080] In the embodiment, the specific range is a range according to a combination of the priority of the UCI and the priority of the UL SCH. In contrast, in Modification 1, the specific range may be a range according to the combination of the priority of the UCI and the priority of the UL SCH and the number of bits of the UCI. Here, HARQ-ACK is exemplified as the UCI. However, the UCI may be CSI part 1, CSI part 2, or SR.

[0081] For example, the combinations of the priority of the UCI and the priority of the UL SCH (here, PUSCH) and the number of bits of the UCI may include (i) a combination of an LP HARQ-ACK and an LP PUSCH with a number of bits equal to or less than a threshold N1, (ii) a combination of an LP HARQ-ACK and an LP PUSCH with a number of bits greater than the threshold N1 and equal to or less than a threshold N2 (>N1), and (iii) a combination of an LP HARQ-ACK and an LP PUSCH with a number of bits greater than the threshold N2. (i) An index associated with a specific range corresponding to a combination of an LP HARQ-ACK and an LP PUSCH with a number of bits equal to or less than the threshold N1 may be referred to as betaOffsetACK-Index1. (ii) An index associated with a specific range corresponding to a combination of an LP HARQ-ACK and an LP PUSCH with a number of bits greater than the threshold N1 and equal to or less than a threshold N2 (>N1) may be referred to as betaOffsetACK-Index2. (iii) An index associated with a specific range according to a combination of an LP HARQ-ACK and an LP PUSCH with a bit number greater than the threshold N2 may be referred to as betaOffsetACK-Index3.

[0082] The combinations of UCI priority and PUSCH priority and the number of UCI bits may include (iv) a combination of an LP HARQ-ACK with a number of bits equal to or less than a threshold N3 and an HP PUSCH, (v) a combination of an LP HARQ-ACK with a number of bits greater than the threshold N3 and equal to or less than a threshold N4 (>N3), and (vi) a combination of an LP HARQ-ACK with a number of bits greater than the threshold N4 and an HP PUSCH. (iv) An index associated with a specific range corresponding to a combination of an LP HARQ-ACK with a number of bits equal to or less than the threshold N3 and an HP PUSCH may be referred to as betaOffsetACK-Index4. (v) An index associated with a specific range corresponding to a combination of an LP HARQ-ACK with a number of bits greater than the threshold N3 and equal to or less than a threshold N4 (>N3) may be referred to as betaOffsetACK-Index5. (vi) An index associated with a specific range corresponding to a combination of an LP HARQ-ACK with a number of bits greater than the threshold N4 and an HP PUSCH may be referred to as betaOffsetACK-Index6.

[0083] The combinations of UCI priority and PUSCH priority and the number of UCI bits may include (vii) a combination of an HP HARQ-ACK and an LP PUSCH with a number of bits equal to or less than a threshold N5, (viii) a combination of an HP HARQ-ACK and an LP PUSCH with a number of bits greater than the threshold N5 and equal to or less than a threshold N6 (>N5), and (ix) a combination of an HP HARQ-ACK and an LP PUSCH with a number of bits greater than the threshold N6. (vii) An index associated with a specific range corresponding to a combination of an HP HARQ-ACK and an LP PUSCH with a number of bits equal to or less than the threshold N5 may be referred to as betaOffsetACK-Index7. (viii) An index associated with a specific range corresponding to a combination of an HP HARQ-ACK and an LP PUSCH with a number of bits greater than the threshold N5 and equal to or less than the threshold N6 (>N5) may be referred to as betaOffsetACK-Index8. (ix) An index associated with a specific range corresponding to a combination of an HP HARQ-ACK and an LP PUSCH with a number of bits greater than the threshold N6 may be referred to as betaOffsetACK-Index9.

[0084] The combinations of UCI priority and PUSCH priority and the number of UCI bits may include (x) a combination of an HP HARQ-ACK and an HP PUSCH with a number of bits equal to or less than a threshold N7, (xi) a combination of an HP HARQ-ACK and an HP PUSCH with a number of bits greater than the threshold N7 and equal to or less than a threshold N8 (>N7), and (xii) a combination of an HP HARQ-ACK and an HP PUSCH with a number of bits greater than the threshold N8. (x) An index associated with a specific range corresponding to a combination of an HP HARQ-ACK and an HP PUSCH with a number of bits equal to or less than the threshold N7 may be referred to as betaOffsetACK-Index10. (xi) An index associated with a specific range corresponding to a combination of an HP HARQ-ACK and an HP PUSCH with a number of bits greater than the threshold N7 and equal to or less than a threshold N8 (>N7) may be referred to as betaOffsetACK-Index11. (xii) An index associated with a specific range according to a combination of HP HARQ-ACK and HP PUSCH with a bit number greater than the threshold N8 may be referred to as betaOffsetACK-Index12.

[0085] A specific range corresponding to a combination of HARQ-ACK and PUSCH having the same priority may be excluded. In other words, the specified range shown in FIG. 8 may be used as the range of the coefficient (β) corresponding to a combination of HARQ-ACK and PUSCH having the same priority.

[0086] A specific range corresponding to a combination selected from the above combinations (i) to (xii) may be excluded. For example, (v) a specific range corresponding to a combination of LP HARQ-ACK and HP PUSCH with a bit number greater than threshold N3 and equal to or less than threshold N4 (>N3) may be excluded.

[0087] As a setting configuration of the specific range (betaOffsetACK-Index1 to betaOffsetACK-Index12) according to the combination of the UCI priority and the UL SCH priority, the setting configuration shown in FIG. 13 may be adopted.

[0088] As the RRC message, the RRC message shown in FIG. 10 or the RRC message shown in FIG. 11 may be used.

[0089] [Change Example 2] Modification 2 of the embodiment will be described below, focusing mainly on the differences from the embodiment.

[0090] The specific range may be applied based on one or more information elements selected from an RRC message, UE Capability, and DCI. For example, based on one or more information elements selected from an RRC message, UE Capability, and DCI, in a case where UCI and UL SCH with different priorities are supported (e.g., a case where UCI and UL SCH with different priorities are activated), if the DCI format includes a one-bit or two-bit beta_offset indicator, a new coefficient (β) may be applied instead of the existing coefficient (β). For example, the new coefficient (β) may be BetaOffsetsPrio-r17.

[0091] The specific range may be applied based on a newly defined DCI field. The newly defined DCI field may be a field that stores an information element that identifies whether the beta_offset indicator indicates a new coefficient (β) or an existing coefficient (β). The newly defined DCI field may be used when a specific RRC parameter is set. For example, the newly defined DCI field may be used when the newly introduced betaOffsetForPrio is set. The size of the newly defined DCI field may be 1 bit. When "1" is set in the newly defined DCI field, the new coefficient (β) may be applied. The newly defined DCI field may be used when the DCI format is a specific format (DCI_Format_0_1 or DCI_Format_0_2).

[0092] The specific range may be applied based on the RNTI. For example, when the DCI format includes a one-bit or two-bit beta_offset indicator and the DCI is scrambled by a specific RNTI (e.g., MCS-C-RNTI), a new coefficient (β) may be applied instead of the existing coefficient (β). For example, the new coefficient (β) may be BetaOffsetsPrio-r17.

[0093] [Change Example 3] The third modification of the embodiment will be described below, focusing mainly on the differences from the embodiment.

[0094] In Modification 3, a case will be described in which four or more specific ranges are introduced to multiplex one type of UCI onto a PUSCH. The specific ranges correspond to the bit size of the UCI.

[0095] For example, a specific range (beta-offsets) M1 (M1≧1) for multiplexing HP HARQ-ACK onto HP PUSCH may be applied as follows.

[0096] When M1 is 1, betaOffsetACK-Index-1 is applied when multiplexing HP HARQ-ACK on PUSCH regardless of the number of bits of HP HARQ-ACK. When M1 is greater than 1, betaOffsetACK-Index-1 is applied when multiplexing HP HARQ-ACK with a number of bits less than or equal to N1 on PUSCH, and N m-1 (1 < m < M1) greater than and N m When multiplexing HP HARQ-ACK with a number of bits (1 < m < M1) less than or equal to on PUSCH, betaOffsetACK-Index-m is applied, and N M_1 When multiplexing HP HARQ-ACK with a number of bits greater than or equal to the above on PUSCH, betaOffsetACK-Index-M1 may be applied.

[0097] For example, for a specific range (beta-offsetts) M2 (M2 ≥ 1) for multiplexing HP HARQ-ACK on HP PUSCH, it may be applied as follows.

[0098] When M2 is 1, betaOffsetACK-Index-(M1 + 1) is applied when multiplexing HP HARQ-ACK on PUSCH regardless of the number of bits of HP HARQ-ACK. When M2 is greater than 1, N (M_1+1) When multiplexing HP HARQ-ACK with a number of bits less than or equal to the following on PUSCH, betaOffsetACK-Index-(M1 + 1) is applied, and N m-1 (M1 + 1 < m < M1 + M2) greater than and N m When multiplexing HP HARQ-ACK with a number of bits (M1 + 1 < m < M1 + M2) less than or equal to the following on PUSCH, betaOffsetACK-Index-m is applied, and N (M_1+M_2) When multiplexing HP HARQ-ACK with a number of bits greater than or equal to the above on PUSCH, betaOffsetACK-Index-(M1 + M2) may be applied.

[0099] For example, for a specific range (beta - offsetts) M3 (M3 ≥ 1) for multiplexing HP HARQ - ACK onto HP PUSCH, it may be applied as follows.

[0100] When M3 is 1, regardless of the number of bits of HP HARQ - ACK, when multiplexing HP HARQ - ACK onto PUSCH, betaOffsetACK - Index - (M1 + M2 + 1) is applied. When M3 is greater than 1, N (M_1+M_2+1) When multiplexing HP HARQ - ACK with the following number of bits onto PUSCH, betaOffsetACK - Index - (M1 + M2 + 1) is applied, and N m-1 (M1 + M2 + 1 < m < M1 + M2 + M3) greater than N m When multiplexing HP HARQ - ACK with the number of bits (M1 + M2 + 1 < m < M1 + M2 + M3) onto PUSCH, betaOffsetACK - Index - m is applied, and N (M_1+M_2+M_3) When multiplexing HP HARQ - ACK greater than N, betaOffsetACK - Index - (M1 + M2 + M3) may be applied.

[0101] For example, for a specific range (beta - offsetts) M4 (M4 ≥ 1) for multiplexing HP HARQ - ACK onto HP PUSCH, it may be applied as follows.

[0102] When M4 is 1, regardless of the number of bits of HP HARQ - ACK, when multiplexing HP HARQ - ACK onto PUSCH, betaOffsetACK - Index - (M1 + M2 + M3 + 1) is applied. When M4 is greater than 1, N (M_1+M_2+M_3+1) When multiplexing HP HARQ - ACK with the following number of bits onto PUSCH, betaOffsetACK - Index - (M1 + M2 + M3 + 1) is applied, and N m-1 (M1 + M2 + M3 + 1 < m < M1 + M2 + M3 + M4) greater than N mWhen multiplexing HP HARQ-ACK with the following number of bits (M1 + M2 + M3 + 1 < m < M1 + M2 + M3 + M4) on PUSCH, betaOffsetACK-Index-m is applied, and N (M_1+M_2+M_3+M_4) When multiplexing HP HARQ-ACK larger than (M_1+M_2+M_3+M_4) on PUSCH, betaOffsetACK-Index-(M1 + M2 + M3 + M4) may be applied.

[0103] Note that "M1 ≥ 1", "M2 ≥ 1", "M3 ≥ 1" and "M4 ≥ 1" may be predefined or determined by the gNB. "N m " and "M1 + M2 + M3 + M4" may be predefined or determined by the gNB.

[0104] [Other Embodiments] The content of the present invention has been described along with the embodiments above. However, the present invention is not limited to these descriptions, and it is obvious to those skilled in the art that various modifications and improvements are possible.

[0105] In the above disclosure, HARQ-ACK has been mainly described. However, the above disclosure is not limited thereto. The UCI multiplexed on UL-SCH may include CSI Part 1 or CSI Part 2. In such a case, the specific range may be a range according to the combination of the priority of UCI and the priority of PUSCH and the type of UCI.

[0106] Although not particularly mentioned in the above disclosure, the priority may be defined as follows. For example, the priority of HARQ-ACK may be higher than the priority of SR. The priority regarding URLLC (Ultra Reliable and Low Latency Communications) may be higher than the priority regarding eMBB (enhanced Mobile BroadBand). ​​The block diagram (FIG. 4) used in the description of the above-described embodiment shows functional blocks. These functional blocks (components) are realized by any combination of at least one of hardware and software. Furthermore, the method for realizing each functional block is not particularly limited. That is, each functional block may be realized using a single device that is physically or logically coupled, or may be realized using two or more physically or logically separated devices that are connected directly or indirectly (for example, by wire, wirelessly, etc.) and these multiple devices. The functional block may also be realized by combining the single device or multiple devices with software.

[0108] Functions include, but are not limited to, judgment, determination, judgment, calculation, computation, processing, derivation, investigation, search, confirmation, reception, transmission, output, access, resolution, selection, election, establishment, comparison, assumption, expectation, regard, broadcasting, notifying, communicating, forwarding, configuring, reconfiguring, allocating, mapping, and assignment. For example, a functional block (component) that performs transmission is called a transmitting unit or transmitter. As mentioned above, there are no particular limitations on how each is implemented.

[0109] Furthermore, the above-described UE 200 (the device) may function as a computer that performs processing of the wireless communication method of the present disclosure. Fig. 14 is a diagram showing an example of the hardware configuration of the device. As shown in Fig. 14, the device may be configured as a computer including a processor 1001, a memory 1002, a storage 1003, a communication device 1004, an input device 1005, an output device 1006, a bus 1007, etc.

[0110] In the following description, the term "apparatus" can be interpreted as a circuit, a device, a unit, etc. The hardware configuration of the apparatus may be configured to include one or more of the apparatuses shown in the drawings, or may be configured to exclude some of the apparatuses.

[0111] Each functional block of the device (see FIG. 4) is realized by any hardware element of the computer device or a combination of the hardware elements.

[0112] In addition, each function of the device is realized by loading specified software (programs) onto hardware such as processor 1001 and memory 1002, causing processor 1001 to perform calculations, control communication via communication device 1004, and control at least one of reading and writing data in memory 1002 and storage 1003.

[0113] The processor 1001 controls the entire computer by running, for example, an operating system, and may be configured as a central processing unit (CPU) including an interface with peripheral devices, a control unit, an arithmetic unit, a register, and the like.

[0114] The processor 1001 also reads programs (program codes), software modules, data, etc. from at least one of the storage 1003 and the communication device 1004 into the memory 1002, and executes various processes in accordance with these. The programs used are those that cause a computer to execute at least some of the operations described in the above-mentioned embodiments. Furthermore, the various processes described above may be executed by one processor 1001, or may be executed simultaneously or sequentially by two or more processors 1001. The processor 1001 may be implemented by one or more chips. The programs may be transmitted from a network via a telecommunications line.

[0115] The memory 1002 is a computer-readable recording medium and may be configured by, for example, 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 called a register, a cache, a main memory (primary storage device), etc. The memory 1002 can store a program (program code), a software module, etc., that can execute a method according to an embodiment of the present disclosure.

The above-mentioned recording medium may be, for example, a database, a server, or other appropriate medium including at least one of memory 1002 and storage 1003.

[0117] The communication device 1004 is hardware (transmission / reception device) for communicating between computers via at least one of a wired network and a wireless network, and is also called, for example, a network device, a network controller, a network card, or a communication module.

[0118] The communication device 1004 may be configured to include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc. to realize, for example, at least one of Frequency Division Duplex (FDD) and Time Division Duplex (TDD).

[0119] The input device 1005 is an input device (for example, a keyboard, a mouse, a microphone, a switch, a button, a sensor, etc.) that receives input from the outside. The output device 1006 is an output device (for example, a display, a speaker, an LED lamp, etc.) that outputs to the outside. The input device 1005 and the output device 1006 may be integrated into one device (for example, a touch panel).

[0120] Furthermore, each device such as the processor 1001 and the memory 1002 is connected to a bus 1007 for communicating information. The bus 1007 may be configured using a single bus, or may be configured using different buses between each device.

[0121] Furthermore, 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), or a field programmable gate array (FPGA), and some or all of the functional blocks may be realized by the hardware. For example, the processor 1001 may be implemented using at least one of these pieces of hardware.

[0122] Furthermore, the notification of information is not limited to the aspects / embodiments described in the present disclosure, and may be performed using other methods. For example, the notification of information may be performed by physical layer signaling (e.g., Downlink Control Information (DCI), Uplink Control Information (UCI)), higher 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. Furthermore, the RRC signaling may be referred to as an RRC message, and may be, for example, an RRC Connection Setup message, an RRC Connection Reconfiguration message, or the like.

[0123] Each aspect / embodiment described in the present disclosure may be applied to at least one of a system using Long Term Evolution (LTE), LTE-Advanced (LTE-A), SUPER 3G, IMT-Advanced, a 4th generation mobile communication system (4G), a 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, Ultra-WideBand (UWB), Bluetooth (registered trademark), or other suitable system, and a next-generation system extended based on these. Furthermore, a combination of multiple systems (e.g., a combination of at least one of LTE and LTE-A and 5G) may also be applied.

[0124] The order of the procedures, sequences, flowcharts, etc. of each aspect / embodiment described in this disclosure may be changed unless it is consistent. 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.

[0125] In the present disclosure, a specific operation described as being performed by a base station may be performed by its upper node in some cases. In a network consisting of one or more network nodes having a base station, it is clear that various operations performed for communication with a terminal may be performed by at least one of the base station and another network node other than the base station (for example, 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, a combination of multiple other network nodes (for example, an MME and an S-GW) may also be used.

[0126] Information, signals (information, etc.) 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.

[0127] The input and output information may be stored in a specific location (for example, memory) or may be managed using a management table. The input and output information may be overwritten, updated, or added. The output information may be deleted. The input information may be sent to another device.

[0128] 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).

[0129] 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).

[0130] Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.

[0131] 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.

[0132] The information, signals, etc. described in this disclosure may be represented using any of a variety of different technologies. 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.

[0133] 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.

[0134] As used in this disclosure, the terms "system" and "network" are used interchangeably.

[0135] Furthermore, the information, parameters, etc. described in the present disclosure may be expressed using absolute values, may be expressed using relative values ​​from a predetermined value, or may be expressed using other corresponding information. For example, a radio resource may be indicated by an index.

[0136] 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.

[0137] In this disclosure, terms such as "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," and "component carrier" may be used interchangeably. Base stations may also be referred to by terms such as macrocell, small cell, femtocell, and picocell.

[0138] A base station can accommodate one or more (e.g., three) cells (also called sectors). 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 (Remote Radio Head: RRH)).

[0139] The terms "cell" or "sector" refer to part or all of the coverage area of ​​a base station and / or base station subsystem that provides communication services within that coverage area.

[0140] In this disclosure, the terms "Mobile Station (MS)," "user terminal," "User Equipment (UE)," "terminal," etc. may be used interchangeably.

[0141] 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.

[0142] 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, the mobile body itself, etc. 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 Internet of Things (IoT) device such as a sensor.

[0143] Furthermore, a base station in the present disclosure may be read as a mobile station (user terminal, the same applies hereinafter). For example, the aspects / embodiments of the present disclosure may be applied to a configuration in which communication between a base station and a mobile station is replaced with communication between multiple mobile stations (which may be called, for example, Device-to-Device (D2D) or Vehicle-to-Everything (V2X)). In this case, the mobile station may be configured to have the functions of a base station. Furthermore, terms such as "uplink" and "downlink" may be read as terms corresponding to communication between terminals (for example, "side"). For example, terms such as uplink channel and downlink channel may be read as side channel.

[0144] Similarly, a mobile station in the present disclosure may be interpreted as a base station, in which case the base station may have the functions of a mobile station.

[0145] A radio frame may be composed of one or more frames in the time domain, each of which may be called a subframe.

[0146] A subframe may further be composed of one or more slots in the time domain, and may have a fixed time length (e.g., 1 ms) that is independent of numerology.

[0147] Numerology may be a communication parameter applied 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 a transceiver in the frequency domain, and specific windowing operations performed by a transceiver in the time domain.

[0148] A slot may consist of one or more symbols in the time domain (such as an Orthogonal Frequency Division Multiplexing (OFDM) symbol or a Single Carrier Frequency Division Multiple Access (SC-FDMA) symbol). A slot may be a time unit based on numerology.

[0149] 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.

[0150] 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.

[0151] 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 (e.g., 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.

[0152] 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 radio resources (such as frequency bandwidth and transmission power that can be used by each user terminal) to each user terminal in TTI units. However, the definition of TTI is not limited to this.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and may include one or more consecutive subcarriers in the frequency domain. The number of subcarriers included in an RB may be the same regardless of numerology, for example, 12. The number of subcarriers included in an RB may also be determined based on numerology.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] The BWP may include a BWP for UL (UL BWP) and a BWP for DL ​​(DL BWP). One or more BWPs may be configured for a UE within one carrier.

[0163] At least one of the configured BWPs may be active, and the UE may not expect to transmit or receive a given signal / channel outside the active BWP. Note that the terms "cell," "carrier," etc. in this disclosure may be read as "BWP."

[0164] 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.

[0165] 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.

[0166] The reference signal may also be abbreviated as Reference Signal (RS), and may also be called a pilot depending on the applicable standard.

[0167] 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."

[0168] The "means" in the configuration of each of the above devices may be replaced with "part," "circuit," "device," etc.

[0169] 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 therein or that the first element must precede the second element in some way.

[0170] 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.

[0171] 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.

[0172] 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.

[0173] 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."

[0174] Although the present disclosure has been described in detail above, it is clear to those skilled in the art that the present disclosure is not limited to the embodiments described herein. The present disclosure can be implemented in modified and altered forms without departing from the spirit and scope of the present disclosure as defined by the claims. Therefore, the description of the present disclosure is intended to be illustrative and does not have any limiting meaning on the present disclosure. [Explanation of symbols]
