Description

Technical Field

[0001] The present disclosure relates to a terminal performing wireless communication, and more particularly, to a terminal performing wireless communication using two or more uplink channels having different priorities. Background Art

[0002] The 3rd Generation Partnership Project (3GPP) has standardized the fifth-generation mobile communication system (also called 5G, New Radio (NR) or Next Generation (NG)), and has also promoted the standardization of the next generation called Beyond 5G, 5G Evolution or 6G.

[0003] In Release 15 of 3GPP, multiplexing of more than two uplink channels (PUCCH (Physical Uplink Control Channel) and PUSCH (Physical Uplink Shared Channel) transmitted in the same time slot is supported. In the multiplexing of uplink channels, the multiplexing timeline conditions that should be satisfied by the time between the reception of DCI and the transmission of the uplink channel are determined.

[0004] 3GPP Release 16 (NR) supports prioritization of two or more uplink channels transmitted in the same time slot. In the prioritization of uplink channels, a prioritization timeline condition that should be satisfied by the time between the reception of DCI and the transmission of the uplink channels is determined.

[0005] In addition, in Release 17 of 3GPP, support for multiplexing of uplink channels having different priorities has been negotiated (eg, Non-Patent Document 1).

[0008] Non-patent literature 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

[0009] In this context, the inventors conducted in-depth research and found that it is possible to imagine a situation where the priority timeline condition is satisfied but the multiplexing timeline condition is not satisfied. In other words, the inventors found that when multiplexing of uplink channels with different priorities is imagined, appropriate control related to multiplexing and priority cannot be performed.

[0010] Therefore, the following disclosure has been made in view of the above circumstances, and an object of the present invention is to provide a terminal capable of appropriately controlling multiplexing and priority assignment of uplink channels having different priorities.

[0011] One embodiment of the present disclosure provides a terminal comprising: a communication unit that executes transmission of uplink signals using two or more uplink channels with different priorities; and a control unit that executes multiplexing control related to multiplexing of the two or more uplink channels when a multiplexing timeline condition related to multiplexing of the two or more uplink channels is satisfied, and executes priority control related to priority assignment of the two or more uplink channels when a priority assignment timeline condition related to priority assignment of the two or more uplink channels is satisfied, wherein the control unit determines whether the priority assignment timeline condition is satisfied after determining whether the multiplexing timeline condition is satisfied.

[0026] 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 the description thereof will be appropriately omitted.

[0027] [Implementation Method]

[0028] (1) Overall schematic structure of wireless communication system

[0029] Figure 1 The wireless communication system 10 is a general structure diagram of the wireless communication system 10 according to the embodiment. The wireless communication system 10 is a wireless communication system that complies with the 5G New Radio (NR), and includes a next generation radio access network 20 (Next Generation-Radio Access Network 20, hereinafter referred to as NG-RAN 20), and a terminal 200 (hereinafter referred to as UE200).

[0030] In addition, the wireless communication system 10 may be a wireless communication system that complies with a method called Beyond 5G, 5G Evolution, or 6G.

[0031] 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 Example shown.

[0032] NG-RAN 20 actually includes multiple NG-RAN nodes (Node), specifically, multiple gNBs (or ng-eNBs), which are connected to a 5G-compliant core network (5GC, not shown). In addition, NG-RAN 20 and 5GC can be simply referred to as "network".

[0033] gNB 100A and gNB 100B are wireless base stations that comply with 5G and perform wireless communications that comply with 5G with UE 200. gNB 100A, gNB 100B, and UE 200 are capable of supporting Massive MIMO (Multiple-Input Multiple-Output) that generates a beam BM with higher directivity by controlling wireless signals sent from multiple antenna elements, carrier aggregation (CA) that bundles and uses multiple component carriers (CCs), and dual connectivity (DC) that simultaneously communicates between the UE and two NG-RAN nodes. DC can include MR-DC (Multi-RAT Dual Connectivity) that uses MCG (Master Cell Group) and SCG (Secondary Cell Group). MR-DC includes EN-DC (E-UTRA-NR Dual Connectivity), NE-DC (NR-EUTRA Dual Connectivity), and NR-DC (NR-NR Dual Connectivity). Among them, it can be considered that the CCs (cells) used in CA constitute the same cell group. It can be considered that MCG and SCG constitute the same cell group.

[0034] Furthermore, the wireless communication system 10 supports multiple frequency ranges (FR). Figure 2 A frequency range used in the wireless communication system 10 is shown.

[0035] like Figure 2 As shown, the wireless communication system 10 supports FR1 and FR2. The frequency band of each FR is as follows.

[0036] FR1: 410MHz~7.125GHz

[0037] FR2: 24.25 GHz to 52.6 GHz

[0038] In FR1, a sub-carrier spacing (SCS) of 15, 30 or 60 kHz and a bandwidth (BW) of 5 to 100 MHz can be used. FR2 has a higher frequency than FR1 and can use an SCS of 60 or 120 kHz (including 240 kHz) and a bandwidth (BW) of 50 to 400 MHz.

[0039] In addition, SCS can be interpreted as a numerology. The numerology is defined in 3GPP TS38.300 and corresponds to a subcarrier spacing in the frequency domain.

[0040] 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 and up to 114.25 GHz. Here, for convenience of description, such a high frequency band is referred to as "FR2x".

[0041] To solve this problem, when 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.

[0042] Figure 3 An example of the configuration of a radio frame, a subframe, and a time slot used in the wireless communication system 10 is shown.

[0043] like Figure 3 As shown in the figure, 1 time slot consists of 14 symbols. The larger (wider) the SCS is, the shorter the symbol period (and the time slot period) is. SCS is not limited to Figure 3 The interval (frequency) shown is, for example, 480 kHz, 960 kHz, etc. can be used.

[0044] Furthermore, the number of symbols constituting one slot may not necessarily be 14 symbols (eg, 28 or 56 symbols). Furthermore, the number of slots per subframe may differ according to the SCS.

[0045] in addition, Figure 3 The time direction (t) shown may be referred to as time domain, symbol period, or symbol time, etc. In addition, the frequency direction may also be referred to as frequency domain, resource block, subcarrier, bandwidth part (BWP: Bandwidth part), etc.

[0046] (2) Functional block structure of wireless communication system

[0047] Next, a functional block configuration of the wireless communication system 10 will be described. Specifically, a functional block configuration of the UE 200 will be described.

[0048] Figure 4 is a functional block diagram of UE 200. Figure 4As shown, UE 200 includes a radio signal transceiver 210 , an amplifier 220 , a modulation and demodulation unit 230 , a control signal and reference signal processing unit 240 , an encoding and decoding unit 250 , a data transceiver 260 , and a control unit 270 .

[0049] The wireless signal transceiver 210 transmits and receives wireless signals according to NR. The wireless signal transceiver 210 supports Massive MIMO, CA that bundles and uses multiple CCs, and DC that simultaneously communicates between the UE and two NG-RAN nodes.

[0050] 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 modem unit 230 to a predetermined power level. In addition, the amplifier unit 220 amplifies the RF signal output from the wireless signal transceiver unit 210 .

[0051] The modem unit 230 performs data modulation / demodulation, transmission power setting, resource block allocation, etc. according to each predetermined communication destination (gNB100 or other gNB). In the modem unit 230, Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM: Cyclic Prefix-Orthogonal Frequency Division Multiplexing) / Discrete Fourier Transform-Spread (DFT-S-OFDM) can be applied. In addition, DFT-S-OFDM can be used not only for uplink (UL) but also for downlink (DL).

[0052] 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 .

[0053] Specifically, the control signal / 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 / reference signal processing unit 240 transmits various control signals toward the gNB 100 via a predetermined control channel.

[0054] The control signal / reference signal processing unit 240 performs processing using reference signals (RS) such as a demodulation reference signal (DMRS) and a phase tracking reference signal (PTRS).

[0055] DMRS is a terminal-specific reference signal (pilot signal) known between the base station and the terminal for estimating a fading channel used for data demodulation. PTRS is a terminal-specific reference signal for estimating phase noise, which is a problem in high frequency bands.

[0056] In addition, in addition to DMRS and PTRS, reference signals also include a channel state information-reference signal (CSI-RS), a sounding reference signal (SRS), and a positioning reference signal (PRS) for position information.

[0057] In addition, the channels include control channels and data channels. The control channels include PDCCH (Physical Downlink Control Channel), PUCCH (Physical Uplink Control Channel), RACH (Random Access Channel, Downlink Control Information (DCI) including the Random Access Radio Network Temporary Identifier (RA-RNTI)), and Physical Broadcast Channel (PBCH).

[0058] Data channels include PDSCH (Physical Downlink Shared Channel), PUSCH (Physical Uplink Shared Channel), etc. Data refers to data sent via the data channel. The data channel may also be replaced by a shared channel.

[0059] In an embodiment, the control signal / reference signal processing unit 240 performs transmission of an uplink signal using two or more uplink channels with different priorities. The two or more uplink channels with different priorities may be uplink channels corresponding to two or more DCIs. The uplink channels include a physical uplink control channel (PUCCH: Physical Uplink Control Channel) and a physical uplink shared channel (PUSCH: Physical Uplink Shared Channel). The uplink signal may include uplink control information (UCI: Uplink Control Information). The UCI may include an acknowledgment response (HARQ-ACK) for one or more TBs. The UCI may also include an SR (Scheduling Request) requesting scheduling of resources, and may also include CSI (Channel State Information: Channel State Information) indicating the state of the channel. The UCI may be transmitted via the PUCCH or via the PUSCH.

[0060] The encoding / decoding unit 250 performs data segmentation / concatenation and channel coding / decoding, etc. according to each predetermined communication destination (gNB100 or other gNB).

[0061] Specifically, the encoding / decoding unit 250 divides the data output from the data transceiver unit 260 into predetermined sizes and performs channel coding on the divided data. In addition, the encoding / decoding unit 250 decodes the data output from the modulation / demodulation unit 230 and concatenates the decoded data.

[0062] The data transceiver 260 performs transmission and reception of protocol data units (PDU) and service data units (SDU). Specifically, the data transceiver 260 performs assembly / disassembly of PDU / SDU in multiple layers (such as the medium access control layer (MAC), the radio link control layer (RLC), and the packet data convergence protocol layer (PDCP)). In addition, the data transceiver 260 performs error correction and retransmission control of data according to hybrid ARQ (Hybrid automatic repeat request).

[0063] The control unit 270 controls each functional block constituting the UE 200. In particular, in an embodiment, the control unit 270 performs multiplexing control related to multiplexing of two or more uplink channels when a multiplexing timeline condition related to multiplexing of two or more uplink channels is satisfied. The control unit 270 performs priority control related to priority granting of two or more uplink channels when a priority granting timeline condition related to priority granting of two or more uplink channels is satisfied. After determining whether the multiplexing timeline condition is satisfied, the control unit 270 determines whether the priority granting timeline condition is satisfied. The following illustrates UCI as an example of an uplink signal.

[0064] (3) Timeline

[0065] The timeline will be described below. Specifically, the processing timeline related to the processing time of the UE 200, the timeline related to multiplexing control, and the timeline related to priority control will be described.

[0066] (3.1) Timeline related to processing time

[0067] First, refer to Figure 5 The above paragraph describes the case where UCI is sent via PUCCH. Figure 5 As shown in the above paragraph, UE200 must assume that the time between the last codeword of the PDSCH containing the DCI and the first codeword of the PUCCH does not exceed N1+d 1,1 In other words, the processing timeline condition related to the processing time of the UE 200 regarding the PUCCH is that the time between the last symbol of the PDSCH and the first symbol of the PUCCH is N1+d 1,1 N1 is a parameter determined based on the UE Capability and SCS of UE 200. 1,1 It is a parameter determined according to the UE Capability of UE 200 and the Mapping type of PDSCH, etc. (3GPP TS38.214 V16.3.0§5.3 "UE PDSCH processing procedure time").

[0068] Secondly, refer to Figure 5 The following paragraphs describe the case where UCI is sent via PUSCH. Figure 5 As shown in the lower part of the figure, UE200 must assume that the time between the last codeword of the PDCCH containing DCI and the first codeword of the PUSCH does not exceed N2+d 2,1In other words, the processing timeline condition related to the processing time of the UE 200 regarding the PUSCH is that the time between the last symbol of the PDCCH and the first symbol of the PUSCH is N2+d 2,1 N2 is a parameter determined based on the UE Capability and SCS of UE 200. 2,1 This is a parameter determined based on whether the first symbol of the PUSCH includes only the DMRS or the like (3GPP TS 38.214 V16.3.0 §6.4 "UE PUSCH preparation procedure time").

[0069] (3.2) Timeline related to reuse control

[0070] The following reference Figure 6 The multiplexing control of PUCCH and PUSCH in the same time slot is described. Figure 6 As shown, the time between the last symbol of the PDSCH containing the DCI and the first symbol of the first uplink channel (PUCCH) of the UE200 does not exceed N1+d 1,1 +1 codeword, the multiplexing of more than two uplink channels must be assumed. The first uplink channel represents the first uplink channel among the two or more uplink channels multiplexed in the same time slot. The first codeword of the first uplink channel can be called the starting position of the first uplink channel (the first starting position). The first codeword of the first uplink channel can be called S0. In other words, the multiplexing timeline condition related to the multiplexing of more than two uplink channels is that the time between the last codeword of PDSCH and the starting position (S0) of the first uplink channel is N1+d 1,1 +1 symbol or more. N1+d 1,1 +1 is an example of a time threshold (first time threshold) that defines a multiplexing timeline condition.

[0071] In addition, the time between the last symbol of the PDCCH containing the DCI and the start position (S0) of the first uplink channel of the UE 200 does not exceed N2+d 2,1 In the case of +1 symbol, it is necessary to assume the multiplexing of more than two uplink channels. In other words, the timeline condition for the multiplexing of more than two uplink channels is that the time between the last symbol of PDCCH and the start position (S0) of the first uplink channel is N2+d 2,1 +1 symbol or more. N2+d 2,1 +1 is an example of a time threshold (first time threshold) that defines a multiplexing timeline condition.

[0072] UE 200 multiplexes PUCCH and PUSCH when the multiplexing timeline condition is satisfied. UE 200 does not assume that the multiplexing timeline condition is not satisfied, but when the multiplexing timeline condition is not satisfied, both PUCCH and PUSCH may not be transmitted.

[0073] (3.3) Timeline related to priority control

[0074] The following reference Figure 7 The priority control of PUCCH and PUSCH in the same time slot is described.

[0075] like Figure 7 As shown in the upper section, the time between the last codeword of the PDCCH containing the DCI and the first codeword (the above-mentioned S0) of the first uplink channel (PUCCH) of the UE 200 does not exceed N2+d 2,1 In other words, the priority timing condition for the priority of two or more uplink channels is that the time between the last symbol of PDCCH and the start position (S0) of the first uplink channel is N2+d1. 2,1 +d1 symbol or more.

[0076] For example, when the priority assignment timeline condition is met, UE 200 does not send UCI via PUCCH (LP; Low Priority), but sends UCI via PUSCH (HP; High Priority). UE 200 does not envision a situation where the priority assignment timeline condition is not met, but when the priority assignment timeline condition is not met, both PUCCH and PUSCH may not be sent.

[0077] Likewise, if Figure 7 As shown in the lower part of FIG, the time between the last codeword of the PDCCH containing the DCI and the first codeword (the above-mentioned S0) of the first uplink channel (PUSCH) of UE 200 does not exceed N2+d 2,1 In other words, the priority timing condition for the priority of two or more uplink channels is that the time between the last symbol of PDCCH and the start position (S0) of the first uplink channel is N2+d1. 2,1 +d1 symbol or more.

[0078] For example, when the priority timeline condition is met, UE 200 does not send UCI via PUSCH (LP; Low Priority), but sends UCI via PUCCH (HP; High Priority). UE 200 does not assume that the priority timeline condition is not met, but when the priority timeline condition is not met, both PUCCH and PUSCH may not be sent.

[0079] (4)Topics

[0080] As a result of intensive research, the inventors have found that when multiplexing control and priority control are performed on uplink channels having different priorities, the following problems may occur if the above-mentioned time line is assumed.

[0081] First, let's explain Case 1. Figure 8 As shown in the upper section, when focusing on the first PUCCH (LP), the processing timeline condition is that the time between the last codeword of the PDSCH containing the DCI and the start position (S0) of the first uplink channel (here PUCCH (LP)) is N1+d 1,1 In the case of more than symbol (#1), the priority timeline condition is that the time between the last symbol of the PDCCH containing the DCI and the start position (S0) of the first uplink channel (here PUCCH (LP)) is N2+d 2,1 However, the starting point of the time for determining whether the processing timeline condition is satisfied is the last symbol of the PDSCH, whereas the starting point of the time for determining whether the priority assignment timeline condition is satisfied is the last symbol of the PDCCH. Therefore, the time for determining whether the priority assignment timeline condition is satisfied (N2+d 2,1 +d1 symbol), it can be considered that the processing timeline condition (N1+d 1,1 As described above, since the case where the processing timeline condition is not satisfied is not assumed, the action of UE 200 in Case 1 is unclear.

[0082] Second, let's explain Case 2. Figure 8 As shown in the lower part of the figure, when focusing on the first PUCCH (LP), the processing timeline condition is that the time between the last codeword of the PDSCH containing the DCI and the start position (S0) of the first uplink channel (here PUCCH (LP)) is N1+d 1,1In the case of more than symbol (#1), the priority timeline condition is that the time between the last symbol of the PDCCH containing the DCI and the start position (S0) of the first uplink channel (here PUCCH (LP)) is N2+d 2,1 On the other hand, when focusing on the second PUCCH (HP), the processing timeline condition is that the time between the last symbol of the PDSCH containing the DCI and the start position (S0) of the first uplink channel (here PUCCH (LP)) is N1+d 1,1 In this case, the condition (N2+d 2,1 +d1 symbol) and the processing timeline condition of the first PUCCH (LP) (N1+d 1,1 Regardless of symbol (#1), it can be considered that the processing timeline condition (N1+d 1,1 As described above, since the case where the processing timeline condition is not satisfied is not assumed, the action of UE 200 in Case 2 is unclear.

[0083] Third, let's explain Case 3. Fig. 9 As shown in the previous paragraph, the priority timeline condition (N2+d 2,1 +d1 symbol), it can be considered that the multiplexing time line condition (N1+d 1,1 +1 symbol (#1)). Similarly, the case where the priority timeline condition (N2+d 2,1 +d1 symbol), it is also possible to consider not satisfying the multiplexing timeline condition (N2+d 2,1 As described above, since the case where the multiplexing timeline condition is not satisfied is not assumed, the operation of UE 200 in Case 3 is unclear.

[0084] In addition, Case 4 is described. Fig. 9 As shown in the previous paragraph, the priority timeline condition (N2+d 2,1 +d1 symbol) and the multiplexing timeline condition of the first PUSCH (LP) (N2+d 2,1 +1 symbol (#1)), it can be considered that the multiplexing time line condition (N1+d 1,1 As described above, since it is not assumed that the multiplexing timeline condition is not satisfied, the operation of UE 200 in Case 4 is unclear.

[0085] (5) Control example

[0086] As described in the above-mentioned Cases 1 to 4, even if the priority granting timeline condition is satisfied, the processing timeline condition and the multiplexing timeline condition are not satisfied. From this point of view, in the embodiment, UE 200 (control unit 270) performs the following operations.

[0087] Specifically, after determining whether the multiplexing timeline condition is satisfied, the control unit 270 determines whether the priority granting timeline condition is satisfied. That is, the control unit 270 performs multiplexing control of two or more uplink channels when the multiplexing timeline is satisfied. The control unit 270 performs priority control of two or more uplink channels when the multiplexing timeline is not satisfied but the priority granting timeline condition is satisfied. Under this premise, the following structure can be introduced.

[0088] (5.1) Control Example 1

[0089] In control example 1, a new parameter is introduced as a time threshold for defining a multiplexing timeline condition. Specifically, the multiplexing timeline condition includes: a first multiplexing timeline condition used in multiplexing control not based on the priority of two or more uplink channels, and a second multiplexing timeline condition used in multiplexing control based on the priority of two or more uplink channels. The second time threshold for defining the second multiplexing timeline condition is shorter than the first time threshold for defining the first multiplexing timeline condition. Here, the first time threshold is an existing parameter, and the second time threshold is an example of a new parameter.

[0090] For example, Fig.10 As shown in the control example 1-1, the second timeline condition can be introduced as the multiplexing timeline condition related to the second PUCCH (HP). For example, P new .P new is greater than the first time threshold (N1+d 1,1 +1) Short time. new It can be N1+d 1,1 .P new It can be a time threshold that defines the processing timeline condition. Although not specifically limited, for the first PUCCH (LP), the first time threshold (N1+d 1,1 +1). Alternatively, for the first PUCCH (LP), the second time threshold (P new ).

[0091] Likewise, if Fig.10As shown in control example 1-2, the second timeline condition can be introduced as the multiplexing timeline condition related to the second PUSCH. For example, Q is introduced as the time threshold for defining the second multiplexing timeline condition. new .Q new is greater than the first time threshold (N2+d 2,1 +1) Short time. Q new It can be N2+d 2,1 .Q new It may also be a time threshold that defines the processing timeline condition. Although not particularly limited, for the first PUCCH (LP), the first time threshold (N1+d 1,1 +1).

[0092] (5.2) Control Example 2

[0093] In control example 2, a new explanation or a new parameter is introduced regarding the start position of the uplink channel used in the multiplexing timeline condition. Specifically, the multiplexing timeline condition includes: a first multiplexing timeline condition used in multiplexing control not based on the priority of the uplink signal, and a second multiplexing timeline condition used in multiplexing control based on the priority of the uplink signal. The first start position of the uplink channel used in the first multiplexing timeline condition is the start position of the first uplink channel among the two or more uplink channels multiplexed in the multiplexing control (S0 mentioned above). On the other hand, the second start position of the uplink channel used in the second multiplexing timeline condition is the start position of the uplink channel having resources used in the multiplexing control among the two or more uplink channels multiplexed in the multiplexing control (S new ). The second starting position can be considered as an example of a new interpretation, or as an example of a new parameter. Here, the second multiplexing timeline condition can be defined as the time from the last symbol of the PDCCH to S new The time threshold (also called the third time threshold) is greater than N1+d 1,1 +x or N2+d 2,1 +y long time.

[0094] When the first uplink channel is multiplexed with the second uplink channel, the uplink channel having resources used in the multiplexing control indicates the second uplink channel. The priority of the second uplink channel is higher than that of the first uplink channel.

[0095] For example, Fig.11As shown in Example 2-1 of the control of , the second timeline condition can be introduced as the multiplexing timeline condition related to the second PUCCH (HP). The starting position of the uplink channel used in the second multiplexing timeline condition is the starting position (S) of the PUCCH (HP) having the resources used in the multiplexing control. new ). Here, a case where PUCCH (LP) is multiplexed into PUCCH (HP) is illustrated.

[0096] Likewise, if Fig.11 As shown in Example 2-2 of the control, the second timeline condition can be introduced as the multiplexing timeline condition related to the second PUSCH (HP). The starting position of the uplink channel used in the second multiplexing timeline condition is the starting position (S) of the PUSCH (HP) having the resources used in the multiplexing control. new ). Here, a case where PUCCH (LP) is multiplexed into PUSCH (HP) is illustrated.

[0097] Likewise, if Fig.11 As shown in Example 2-3 of the control, the second timeline condition can be introduced as the multiplexing timeline condition related to the second PUCCH (HP). The starting position of the uplink channel used in the second multiplexing timeline condition is the starting position (S) of the PUCCH (HP) having the resources used in the multiplexing control. new ). Here, a case where PUSCH (LP) is multiplexed into PUCCH (HP) is illustrated.

[0098] In addition, regarding the priority timeline condition, the existing parameters (see Figure 7 ). In addition, Control Example 2 and Control Example 3 may be combined.

[0099] (5.3) Control Example 3

[0100] In control example 3, restrictions are set for multiplexing of two or more uplink channels with different priorities. Specifically, the control unit 270 may perform multiplexing control when the starting positions of the two or more uplink channels are consistent. The control unit 270 may also perform priority control instead of multiplexing control when the starting positions of the two or more uplink channels are inconsistent.

[0101] The following, such as Fig.12 As shown, consider the case where PUCCH (LP) is transmitted in time slot units and PUCCH (HP) is transmitted in sub-slot units.

[0102] For example, Fig.12As shown in control example 3-1, the control unit 270 can multiplex PUCCH (HP) #1 with PUCCH (LP) #1 when the starting position of the sub-time slot containing the starting position of PUCCH (HP) #1 coincides with the starting position of the time slot containing the starting position of PUCCH (LP) #1. In other words, when PUCCH (LP) #1 and PUCCH (HP) #1 collide on the same boundary, multiplexing control of PUCCH (LP) #1 and PUCCH (HP) #1 can be performed. In addition, the situation where the starting positions of the time slots or sub-time slots containing the starting positions of more than two uplink channels coincide (that is, more than two uplink channels collide on the same boundary) can be expressed as the starting positions of more than two uplink channels coincide.

[0103] On the other hand, Fig.12 As shown in control example 3-2, when the starting position of the sub-time slot containing the starting position of PUCCH (HP) #2 is inconsistent with the starting position of the time slot containing the starting position of PUCCH (LP) #1, the control unit 270 may not multiplex PUCCH (HP) #2 with PUCCH (LP) #1, but may perform priority control of PUCCH (LP) #1 and PUCCH (HP) #2. In other words, when PUCCH (LP) #1 and PUCCH (HP) #2 do not conflict on the same boundary, priority control of PUCCH (LP) #1 and PUCCH (HP) #2 may be performed. For example, the control unit 270 may not send PUCCH (LP) #1, but may send PUCCH (HP) #2. In addition, the situation where the starting positions of the time slot or sub-time slot containing the starting positions of more than two uplink channels are inconsistent (that is, more than two uplink channels do not conflict on the same boundary) can also be expressed as the starting positions of more than two uplink channels are inconsistent.

[0104] (6) Action example

[0105] An operation example of the embodiment will be described below. The following example illustrates a case where multiplexing control and priority control of two or more uplink channels having different priorities are configured in the UE 200 .

[0106] like Fig.13 As shown, in step S10, UE 200 sends a message including UE capability to NG-RAN 20. UE Capability may include an information element indicating whether multiplexing control of more than two uplink channels with different priorities is supported. UE Capability may also include an information element indicating whether priority control of more than two uplink channels with different priorities is supported.

[0107] In step S11, UE 100 receives an RRC message including PUCCH-Config. associated with multiple CCs from NG-RAN 20. PUCCH-Config. may include an information element indicating whether multiplexing control of two or more uplink channels with different priorities is set. PUCCH-Config. may also include an information element indicating whether priority control of two or more uplink channels with different priorities is set.

[0108] In step S12, the UE 200 receives one or more DCIs from the NG-RAN 20 via the PDCCH. The NG-RAN 20 may send the DCI according to the UE Capability received in step S10. In other words, the DCI may include information elements (e.g., Frequency domain resource assignment, Time domain resource assignment) that specify uplink resources taking into account the UE Capability.

[0109] In step S13, after determining whether the multiplexing timeline condition is satisfied, the UE 200 determines whether the priority granting timeline condition is satisfied. If the multiplexing timeline condition is satisfied, the UE 200 multiplexes two or more uplink channels with different priorities in the same time slot. If the priority granting timeline condition is satisfied, the UE 200 gives priority to two or more uplink channels with different priorities in the same time slot.

[0110] (7) Action and Effect

[0111] In the embodiment, after determining whether the multiplexing timeline condition is satisfied, the UE 200 determines whether the priority timeline condition is satisfied. According to this structure, in the case where the priority timeline condition is satisfied but the multiplexing timeline condition is also satisfied ( Fig. 9 In the cases 3 and 4) shown, it is possible to avoid a situation where the action of UE 200 is unclear, and to perform appropriate control related to multiplexing and priority assignment.

[0112] In the embodiment, a new parameter (second time threshold) is introduced as a time threshold for defining the multiplexing timeline condition, and the second time threshold is shorter than the first time threshold. With this configuration, the delay required for multiplexing two or more uplink channels having different priorities is reduced.

[0113] In the embodiment, a new interpretation or a new parameter (second starting position) is introduced regarding the starting position of the uplink channel used in the multiplexing timeline condition. The second starting position is the starting position of the uplink channel having resources used in the multiplexing control. According to this structure, the multiplexing control can be appropriately performed without affecting the processing associated with the multiplexing.

[0114] [Other embodiments]

[0115] As mentioned above, although the content of this invention was demonstrated based on embodiment, this invention is not limited to these descriptions, and it is obvious to a person skilled in the art that various deformation|transformation and improvement are possible.

[0116] In the above disclosure, UCI is illustrated as an example of an uplink signal. However, the above disclosure is not limited to this. The uplink signal may include a data signal. That is, the above disclosure only needs to be provided for multiplexing and prioritizing of two or more uplink channels with different priorities.

[0117] In the above disclosure, Case 1 to Case 4 are exemplified as the subjects, but the above disclosure is not limited thereto. The above disclosure is applicable to the case where the multiplexing timeline condition is not satisfied, regardless of whether the priority timeline condition is satisfied.

[0118] In the above disclosure, the multiplexing timeline condition is described, but the above disclosure is not limited to this. The above disclosure is independent of satisfying the priority timeline condition and can be applied to the case where the processing timeline condition is not satisfied. In this case, the record related to the multiplexing timeline can be replaced with the record related to the processing timeline. For example, after determining whether the processing timeline condition is satisfied, the UE 200 can determine whether the priority timeline condition is satisfied.

[0119] Although not specifically mentioned in the above disclosure, multiplexing control and priority control can be performed as follows. For example, the priority of the PUCCH related to HARQ-ACK may be higher than the priority of the PUCCH related to SR. In this case, the PUCCH related to SR may be multiplexed to the PUCCH related to HARQ-ACK. In the case where such multiplexing cannot be performed, the PUCCH related to SR may not be sent, while the PUCCH related to HARQ-ACK may be sent. The priority of the PUCCH related to URLLC (UltraReliable and Low Latency Communications) may be higher than the priority of the PUSCH related to eMBB (enhanced Mobile BroadBand). In this case, the PUSCH related to eMBB may not be sent, but the PUCCH related to URLLC may be sent.

[0120] In the above disclosure, UCI is mainly described, but the above disclosure is not limited to this. UCI can be replaced by HARQ-ACK, SR, or CSI. UCI that can be sent using multiple CCs can be any parameter selected from HARQ-ACK, SR, and CSI.

[0121] The block diagram used in the description of the above-mentioned embodiment ( Figure 4 ) shows blocks in units 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 device that is physically or logically combined, or two or more physically or logically separated devices can be directly or indirectly connected (for example, using wires, wirelessly, etc.) and implemented using these multiple devices. The functional block can also be implemented by combining software with the above-mentioned one device or the above-mentioned multiple devices.

[0122] Functionally, it includes judging, deciding, determining, calculating, calculating, processing, deriving, investigating, searching, confirming, receiving, sending, outputting, accessing, solving, selecting, selecting, establishing, comparing, assuming, expecting, regarding, broadcasting, notifying, communicating, forwarding, configuring, reconfiguring, allocating, mapping, assigning, etc., but is not limited to these. For example, the functional block (structural part) that enables the sending function is called a transmitting unit or a transmitter. In short, as mentioned above, there is no particular limitation on the implementation method.

[0123] Furthermore, the above-mentioned UE 200 (the device) may also function as a computer that performs the processing of the wireless communication method of the present disclosure.

[0125] Each functional block of the device (refer to Figure 4 ) is implemented by any hardware element or combination of hardware elements of the computer device.

[0126] In addition, each function in the device is implemented by the following method: predetermined software (program) is read into hardware such as processor 1001 and memory 1002, so that processor 1001 performs calculations and controls the communication of communication device 1004 or controls at least one of the reading and writing of data in memory 1002 and storage 1003.

[0127] The processor 1001 controls the entire computer by, for example, executing an operating system. The processor 1001 may be constituted by a central processing unit (CPU) including an interface with peripheral devices, a control device, a calculation device, a register, and the like.

[0128] In addition, the processor 1001 reads a program (program code), a software module or data, etc. from at least one of the memory 1003 and the communication device 1004 to the memory 1002, and performs various processes accordingly. As a program, a program that causes a computer to perform at least a part of the actions described in the above-mentioned embodiments is used. In addition, with respect to the above-mentioned various processes, although it is described that the above-mentioned various processes are performed by one processor 1001, the above-mentioned various processes can also be performed simultaneously or sequentially by more than two processors 1001. The processor 1001 can also be installed by more than one chip. In addition, the program can also be sent from the network via a telecommunication line.

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

[0131] The communication device 1004 is hardware (transceiver) used to communicate between computers via at least one of a wired network and a wireless network, and may also be called a network device, a network controller, a network card, a communication module, etc.

[0132] The communication device 1004 may be configured to include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc., for example, in order to realize at least one of frequency division duplex (FDD) and time division duplex (TDD).

[0133] The input device 1005 is an input device that receives input from the outside (e.g., a keyboard, a mouse, a microphone, a switch, a button, a sensor, etc.). The output device 1006 is an output device that implements output to the outside (e.g., a display, a speaker, an LED light, etc.). In addition, the input device 1005 and the output device 1006 may also be integrally formed (e.g., a touch panel).

[0134] In addition, the processor 1001 and the memory 1002 and other devices are connected via a bus 1007 for communicating information. The bus 1007 may be configured using a single bus or may be configured using different buses for each device.

[0135] 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 be implemented by the hardware. For example, the processor 1001 may also be installed using at least one of these hardware.

[0136] In addition, the notification of information is not limited to the form / implementation method 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 (Downlink Control Information: DCI), uplink control information (Uplink Control Information: UCI)), high-level signaling (e.g., RRC signaling, medium access control (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, an RRC Connection Setup message, an RRC Connection Reconfiguration message, etc.

[0137] Each form / embodiment described in the present disclosure may 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), CDMA 2000, 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), a system using other appropriate systems, and a next-generation system extended therefrom. In addition, a combination of a plurality of systems (for example, a combination of at least one of LTE and LTE-A with 5G, etc.) may also be applied.

[0138] The processing procedures, timings, processes, etc. of each form / implementation described in this disclosure may be changed in order without contradiction. For example, for the method described in this disclosure, the elements of various steps are presented in an illustrative order, but are not limited to the specific order presented.

[0139] In the present disclosure, specific actions performed by a base station are sometimes performed by its upper node depending on the situation. In a network consisting of one or more network nodes having a base station, various actions performed to communicate 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, consider MME or S-GW, etc., but 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 node may also be a combination of multiple other network nodes (for example, MME and S-GW).

[0140] Information, signals (information, etc.) can be output from a higher layer (or lower layer) to a lower layer (or higher layer), and can also be input or output via multiple network nodes.

[0141] The input or output information can be stored in a specific location (e.g., memory) or 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.

[0142] The determination may be made by a value represented by one bit (0 or 1), by a Boolean value (Boolean: true or false), or by comparison of numerical values ​​(for example, comparison with a predetermined value).

[0143] Each form / implementation described in the present disclosure may be used alone or in combination, and may be switched depending on the execution. In addition, notification of scheduled information is not limited to being performed explicitly (e.g., notification of "yes X"), but may also be performed implicitly (e.g., notification of the scheduled information is not performed).

[0144] Software, whether referred to as software, firmware, middleware, microcode, hardware description language, or by other names, shall be interpreted broadly to refer to commands, sets of commands, codes, code segments, program codes, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions, etc.

[0145] In addition, software, commands, information, etc. may be sent and received via a transmission medium. For example, when software is sent from a web page, server, or other remote source using at least one of wired technology (coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), etc.) and wireless technology (infrared, microwave, etc.), at least one of these wired technology and wireless technology is included in the definition of transmission medium.

[0146] The information, signals, etc. described in the present disclosure may also be represented by any of a variety of different technologies. For example, data, commands, instructions, information, signals, bits, symbols, chips, etc. that may be involved in the above description as a whole may be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or photons, or any combination thereof.

[0147] In addition, the terms described in the present disclosure and the terms required for understanding the present 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.

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

[0149] In addition, the information, parameters, etc. described in the present disclosure may be represented by absolute values, relative values ​​to predetermined values, or other corresponding information. For example, wireless resources may also be indicated by indexes.

[0150] The names used for the above parameters are not limiting in any way. Furthermore, the formulas etc. using these parameters may sometimes differ from those explicitly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements may be identified by appropriate names, and therefore the various names assigned to these various channels and information elements are not limiting in any way.

[0151] In the present disclosure, the terms "base station (BS)", "wireless 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" and the like are used interchangeably. Sometimes, a base station is also referred to as a macro cell, a small cell, a micro cell, a pico cell, etc.

[0152] 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, each of which can also provide communication services through a base station subsystem (e.g., a small base station for indoor use (Remote Radio Head: RRH).

[0153] The terms "cell" or "sector" refer to a part or the entirety of a coverage area of ​​at least one of a base station and a base station subsystem that provide communication services within the coverage area.

[0154] In the present disclosure, terms such as “mobile station (MS)”, “user terminal (user terminal)”, “user equipment (UE)”, and “terminal” may be used interchangeably.

[0155] For mobile stations, those skilled in the art sometimes also use the following terms: 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 appropriate terms.

[0156] 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 mobile body, the mobile body itself, etc. The mobile body may be a means of transportation (e.g., a car, an airplane, etc.), a mobile body that moves in an unmanned manner (e.g., a drone, an autonomous vehicle, etc.), or a robot (manned or unmanned). In addition, at least one of the base station and the mobile station also includes a device that does not necessarily move during communication operations. For example, at least one of the base station and the mobile station may be an Internet of Things (IoT) device such as a sensor.

[0157] In addition, the base station in the present disclosure may also be replaced by a mobile station (user terminal, the same below). For example, various forms / implementations of the present disclosure may also be applied to a structure in which the communication between a base station and a mobile station is replaced by communication between multiple mobile stations (for example, may also be referred to as device-to-device (D2D), vehicle-to-everything (V2X), etc.). In this case, it is also possible to set a structure in which the mobile station has the functions of the base station. In addition, terms such as "uplink" and "downlink" may also be replaced by terms corresponding to communication between terminals (for example, "side"). For example, uplink channels, downlink channels, etc. may also be replaced by side channels.

[0158] Likewise, the mobile station in the present disclosure may be replaced by a base station. In this case, the base station may have the same functions as the mobile station.

[0159] A radio frame may be composed of one or more frames in the time domain. In the time domain, one or more frames may be referred to as subframes.

[0160] A subframe may consist of one or more time slots in the time domain. A subframe may be a fixed time length (eg, 1 ms) that is independent of numerology.

[0161] A parameter set may be a communication parameter applied to at least one of the transmission and reception of a certain signal or channel. The parameter set may, for example, represent at least one of a subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, wireless frame structure, specific filtering processing performed by a transceiver in the frequency domain, specific windowing processing performed by a transceiver in the time domain, and the like.

[0162] A slot may 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. A slot may be a time unit based on a parameter set.

[0163] A time slot may contain multiple mini-slots. Each mini-slot may be composed of one or more symbols in the time domain. In addition, a mini-slot may also be referred to as a sub-slot. A mini-slot may be composed of fewer symbols than a time slot. A PDSCH (or PUSCH) transmitted in units of time greater than a mini-slot may be referred to as a PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot may be referred to as a PDSCH (or PUSCH) mapping type B.

[0164] A radio frame, a subframe, a time slot, a mini-time slot, and a symbol all represent time units for transmitting signals. A radio frame, a subframe, a time slot, a mini-time slot, and a symbol may be referred to by other corresponding names.

[0165] For example, 1 subframe can be called a transmission time interval (TTI), multiple consecutive subframes can also be called a TTI, and 1 time slot or 1 mini time slot can also be called a TTI. That is, at least one of the subframe and the TTI can be a subframe (1ms) in the existing LTE, or a period shorter than 1ms (for example, 1-13 code elements), or a period longer than 1ms. In addition, the unit representing TTI can be a time slot, a mini time slot, etc. instead of a subframe.

[0166] Here, TTI refers to, for example, the minimum time unit for scheduling in wireless communication. For example, in the LTE system, the base station schedules the allocation of wireless resources (frequency bandwidth, transmission power, etc. that can be used in each user terminal) to each user terminal in units of TTI. In addition, the definition of TTI is not limited to this.

[0167] TTI can be a transmission time unit for data packets (transport blocks), code blocks, code words, etc. after channel coding, or a processing unit for scheduling, link adaptation, etc. In addition, when TTI is assigned, the time interval (e.g., the number of symbols) to which the transport block, code block, code word, etc. is actually mapped can be shorter than the TTI.

[0168] In addition, when 1 time slot or 1 mini time slot is called TTI, more than one TTI (ie, more than one time slot or more than one mini time slot) can constitute the minimum time unit of scheduling. In addition, the number of time slots (mini time slots) constituting the minimum time unit of scheduling can be controlled.

[0169] A TTI having a time length of 1 ms is also called a normal TTI (TTI in LTE Rel.8-12), a normal TTI, a long TTI, a normal subframe, a normal subframe, a long subframe, a time slot, etc. A TTI shorter than a normal TTI may be called a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a mini-time slot, a sub-time slot, a time slot, etc.

[0170] In addition, for a long TTI (for example, a normal TTI, a subframe, etc.), it can be replaced with a TTI having a time length exceeding 1ms, and for a short TTI (for example, a shortened TTI, etc.), it can be replaced with a TTI length that is smaller than the long TTI (longTTI) and has a TTI length of more than 1ms.

[0171] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain. In the frequency domain, it may contain one or more consecutive subcarriers. The number of subcarriers contained in an RB may be the same regardless of the parameter set, for example, it may be 12. The number of subcarriers contained in an RB may also be determined according to the parameter set.

[0172] In addition, the time domain of an RB may include one or more symbols, and may be the length of 1 slot, 1 mini slot, 1 subframe, or 1 TTI. 1 TTI, 1 subframe, etc. may be composed of one or more resource blocks, respectively.

[0173] In addition, one or more RBs may be referred to as a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, and the like.

[0174] In addition, a resource block may be composed of one or more resource elements (RE). For example, 1 RE may be a radio resource region of 1 subcarrier and 1 symbol.

[0175] A Bandwidth Part (BWP) (also called a partial bandwidth, etc.) represents a subset of contiguous common RBs (common resource blocks) for a parameter set in a certain carrier. Here, a common RB can be identified by the index of the RB based on the common reference point of the carrier. PRBs are defined in a certain BWP and numbered within the BWP.

[0176] 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.

[0177] At least one of the set BWPs may be active, and it is not assumed that the UE transmits or receives a predetermined signal / channel outside the activated BWP. In addition, "cell", "carrier" and the like in the present disclosure may be replaced with "BWP".

[0178] The above structures of radio frames, subframes, time slots, mini-time slots, and symbols are only examples. For example, the number of subframes included in a radio frame, the number of time slots per subframe 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 subcarriers included in an RB, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, and the like can be changed in various ways.

[0179] The terms "connected", "coupled" or all variations of these terms are intended to indicate any direct or indirect connection or combination between two or more elements, and may include the situation where there is one or more intermediate elements between two elements that are "connected" or "coupled" to each other. The combination or connection between elements may be a physical combination or connection, a logical combination or connection, or a combination of these. For example, "access" may be used to replace "connection". In the context of the present disclosure, for two elements, it may be considered that they are "connected" or "coupled" to each other by using at least one of one or more 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 light (including both visible and invisible) region, etc.

[0180] The reference signal may be referred to as Reference Signal (RS) for short, or may be referred to as a pilot signal depending on the applied standard.

[0181] The phrase "according to" used in the present disclosure does not mean "only according to" unless otherwise expressly stated. In other words, the phrase "according to" means both "only according to" and "at least according to".

[0182] The "unit" in the configuration of each of the above-mentioned devices may be replaced with a "section", "circuit", "device" or the like.

[0183] Any reference to an element using the terms "first", "second", etc. used in this disclosure does not necessarily limit the number and order of these elements. These terms are used in this disclosure as a simple method to distinguish between two or more elements. Therefore, a reference to a first and a second element does not mean that only two elements can be used here or that the first element must precede the second element in any form.

[0184] When the terms "include," "including," and variations thereof are used in the present disclosure, these terms are intended to be inclusive, as is the term "comprising." Furthermore, the term "or" used in the present disclosure does not mean an exclusive or.

[0185] In the present disclosure, when an article is added by translation, such as a, an, and the in English, for example, the present disclosure also includes the case where the noun following the article is in plural form.

[0186] The terms "determining" and "determining" used in the present disclosure sometimes also include situations of various actions.
