Abstract
Description
[Technical Field]
[0001] The present disclosure relates to a terminal and a wireless communication method that support subband non-overlapping full duplex (SBFD). [Background technology]
[0002] The 3rd Generation Partnership Project (3GPP (registered trademark)) has specified the 5th generation mobile communication system (5G, also known as New Radio (NR) or Next Generation (NG)), and is also working on specifications for the next generation of mobile communication systems, known as Beyond 5G, 5G Evolution, or 6G.
[0003] Release 18 discusses a duplexing scheme that enables simultaneous use of the downlink (DL) and uplink (UL) by utilizing multiple subbands that make up a time division duplexing (TDD) band. This duplexing scheme is called subband non-overlapping full duplex (SBFD). Note that symbols to which SBFD is applied may also be called SBFD symbols. In addition, in SBFD symbols, subbands used for DL may also be called DL subbands, and subbands used for UL may also be called UL subbands.
[0004] Furthermore, support for initial access (random access (RA)) in SBFD is being considered in Release 19 (Non-Patent Document 1). Specifically, it is being considered to extend the transmission and reception of messages in RA to SBFD symbols.
[0005] In RA, a terminal (hereinafter also referred to as user equipment (UE)) transmits and receives the following messages to and from a base station (hereinafter also referred to as gNodeB (gNB)). First, the UE transmits a preamble in a valid random access opportunity (RO). Second, the UE receives a Random Access Response (RAR). Third, the UE transmits Msg3 as an RRC connection request message. Fourth, the UE 200 receives Msg4 as a contention resolution message. Finally, the UE transmits a Hybrid Automatic Repeat Request (HARQ)-ACK for Msg4. This HARQ-ACK for Msg4 is also called Msg4 HARQ-ACK, Msg4 HARQ-ACK PUCCH, or PUCCH with HARQ-ACK. [Prior art documents] [Non-patent literature]
[0006] [Non-Patent Document 1] “New WID: Evolution of NR duplex operation: Sub-band full duplex (SBFD)”, RP-234035, 3GPP TSG RAN Meeting #102, 3GPP, December 11-15, 2023 Summary of the Invention
[0007] When time division duplexing (TDD) is applied to resource allocation, the PUCCH resource for the Msg4 HARQ-ACK PUCCH in RA is determined according to Table 9.2.1-1 (see FIG. 7) shown in 3GPP TS 38.213, section 9.2.1. For example, the physical resource block (PRB) offset is determined according to this Table 9.2.1-1. Furthermore, when FR2-2 is applied, the number of PRBs can be configured by pucch-ConfigCommon.
[0008] The position (starting PRB) of the PUCCH resource for the Msg4 HARQ-ACK PUCCH is determined according to the PRB offset shown in Table 9.2.1-1 so as to fit within the UL BWP size of a non-SBFD symbol (UL symbol) to which TDD is applied. However, when SBFD is applied to resource allocation, if the starting PRB of the PUCCH resource is determined according to the PRB offset shown in Table 9.2.1-1, there is a risk that the PUCCH resource will be configured outside the UL subband (i.e., the DL subband) even if it is within the BWP size of the SBFD symbol. Furthermore, under such an assumption, the UE may transmit the Msg4 HARQ-ACK PUCCH outside the UL subband.
[0009] Therefore, an object of the present disclosure is to provide a terminal that can appropriately configure PUCCH resources for Msg4 HARQ-ACK PUCCH and transmit Msg4 HARQ-ACK PUCCH in the UL subband of the SBFD symbol, even when SBFD is applied to resource allocation.
[0010] One aspect of the disclosure is a terminal including: a receiving unit that receives configuration information for setting a resource of a physical uplink control channel related to initial access to an uplink subband among a plurality of subbands available in a time division duplex band; a control unit that assumes, based on the configuration information, that the position of the resource is determined based on an edge of the uplink subband; and a transmitting unit that transmits the physical uplink control channel at the position of the resource.

[0013] 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.
[0014] (1) Wireless communication system configuration 1 is a wireless communication system conforming to a scheme called 5G. Alternatively, the wireless communication system 10 may be a wireless communication system conforming to a scheme called Beyond 5G, 5G Evolution, or 6G.
[0015] The wireless communication system 10 can support Massive Multiple-Input Multiple-Output (Massive MIMO), which generates more directional beams by controlling wireless signals transmitted from multiple antenna elements, Carrier Aggregation (CA), which uses multiple component carriers (CCs) as a bundle, and Dual Connectivity (DC), which communicates simultaneously with two base stations.
[0016] As shown in FIG. 1, a wireless communication system 10 includes a base station 100 (hereinafter also referred to as a gNodeB (gNB) 100) constituting a Next Generation-Radio Access Network (NG-RAN) 20, and a terminal 200 (hereinafter also referred to as a user equipment (UE) 200) that performs wireless communication with the gNB 100. The NG-RAN 20 is connected to a core network (CN) (not shown). The CN is composed of multiple network functions (NFs). The NFs are, for example, an access and mobility management function (AMF) and a network data analytics function (NWDAF). The AMF performs, for example, registration of the UE 200. The NWDAF performs, for example, optimization of the CN. Note that the specific configuration of the wireless communication system 10, for example, the number of gNBs 100 and UEs 200, is not limited to the example shown in FIG. 1. The NG-RAN 20 and the CN may be simply referred to as a "network."
[0017] The gNB100 may be divided into a central unit (CU) that is connected to the network and controls the connection with the UE200, and a distributed unit (DU) that is connected to the UE200. The CU may be divided into a CU-CP that controls the control plane (CP) and a CU-UP that controls the user plane (UP). That is, the gNB100 may be divided into a CU-CP, a CU-UP, and a DU.
[0018] Furthermore, the wireless communication system 10 may support a plurality of frequency ranges (FRs). That is, as shown in FIG. 2, the wireless communication system 10 may support the following FRs: FR1: 410MHz~7.125GHz FR2-1: 24.25GHz~52.6GHz ·FR2-2: More than 52.6GHz~71GHz
[0019] In FR1, a subcarrier spacing (SCS) of 15, 30, or 60 kHz and a bandwidth (BW) of 5 to 100 MHz may be used, and in FR2-1, an SCS of 60 or 120 kHz (or 240 kHz) and a BW of 50 to 400 MHz may be used.
[0020] In FR2-2, to avoid an increase in phase noise, Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM) or Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing (DFT-S-OFDM) with a larger SCS may be applied.
[0021] 3, one slot in the wireless communication system 10 is made up of 14 symbols. If this configuration is maintained, the larger (wider) the SCS, the shorter the symbol period (and slot period). Note that the SCS is not limited to the frequencies shown in FIG. 3, and may be, for example, 480 kHz, 960 kHz, or other frequencies.
[0022] Furthermore, the number of symbols constituting one slot does not necessarily have to be 14, but may be, for example, 28 or 56. Furthermore, the number of slots per subframe may differ depending on the SCS.
[0023] (2) Functional block configuration of wireless communication system (2.1) Functional block configuration of the terminal As shown in FIG. 4, the UE 200 includes a radio signal transmitting / receiving unit 210, an amplifier unit 220, a modulation / demodulation unit 230, a control signal / reference signal processing unit 240, an encoding / decoding unit 250, a data transmitting / receiving unit 260, and a control unit 270.
[0024] The radio signal transceiver 210 transmits and receives radio signals to and from the gNB 100. The radio signal transceiver 210 may be configured with a transmitter that transmits radio signals to the gNB 100 and a receiver that receives radio signals from the gNB 100. The radio signals may include data or may be interpreted as data. Transmission may be interpreted as report, notification, etc. Reception may be interpreted as setting (is set), instruction (is given), notification (is given), etc. Note that setting may be realized by configuration information (information element (IE)) of the radio resource control (RRC) layer, and instruction may be realized by a control element (CE) or downlink control information (DCI) of the medium access control (MAC) layer.
[0025] The radio signal transmitting and receiving unit 210 of the embodiment can perform initial access (random access (RA)) to the gNB 100. In the RA, the radio signal transmitting and receiving unit 210 can transmit and receive the above-mentioned Msg1 to Msg4 and Msg4 HARQ-ACK PUCCH. Note that the Msg4 HARQ-ACK PUCCH may be interpreted as a PUCCH related to the initial access.
[0026] The radio signal transmitting / receiving unit 210 of the embodiment can receive configuration information for configuring a PUCCH resource for the Msg4 HARQ-ACK PUCCH. The configuration information may be configuration information for transmitting the Msg4 HARQ-ACK PUCCH in an SBFD symbol (configuration information for SBFD). The configuration information for SBFD may be understood as configuration information for configuring a PUCCH resource for the Msg4 HARQ-ACK PUCCH in an UL subband among multiple subbands (DL subbands and UL subbands) available in a time division duplex (TDD) band. Note that in the present disclosure, the UL subband may be interpreted as UL usable PRBs in the initial BWP.
[0027] Furthermore, the configuration information may be configuration information for transmitting Msg4 HARQ-ACK PUCCH in non-SBFD symbols (non-SBFD configuration information). The non-SBFD configuration information may be understood as non-SBFD configuration information for configuring PUCCH resources in a TDD band in which subbands cannot be used. In other words, the SBFD configuration information may be different from the non-SBFD configuration information.
[0028] The radio signal transmitting and receiving unit 210 according to the embodiment can transmit the Msg4 HARQ-ACK PUCCH at the position (start PRB) of the PUCCH resource assumed by the control unit 270, which will be described later.
[0029] The amplifier unit 220 is configured by a power amplifier (PA) / low noise amplifier (LNA), etc. The amplifier unit 220 amplifies the radio signal output from the radio signal transmitting / receiving unit 210. The amplifier unit 220 also amplifies the radio signal output from the modulation / demodulation unit 230.
[0030] The modem unit 230 performs data modulation / demodulation, transmission power setting, resource block allocation, etc. for each predetermined communication destination (gNB100 or another gNB100). CP-OFDM / DFT-S-OFDM may be applied to the modem unit 230. DFT-S-OFDM may also be used not only for the uplink (UL) but also for the downlink (DL).
[0031] The control signal / reference signal processing unit 240 performs processing related to control signals transmitted and received between the gNB 100, such as radio resource control (RRC) signaling.
[0032] The control signal / reference signal processing unit 240 performs processing related to reference signals transmitted and received between the gNB 100, such as Demodulation Reference Signal (DMRS), Phase Tracking Reference Signal (PTRS), Channel State Information-Reference Signal (CSI-RS), Sounding Reference Signal (SRS), and Positioning Reference Signal (PRS).
[0033] The channels include control channels and data channels. The control channels include a physical uplink control channel (PUCCH), a physical downlink control channel (PDCCH), a physical random access channel (PRACH), a physical broadcast channel (PBCH), etc. The data channels include a physical uplink shared channel (PUSCH), a physical downlink shared channel (PDSCH), etc.
[0034] The encoding / decoding unit 250 performs division / concatenation and coding / decoding of data contained in the radio signal for each predetermined communication destination (gNB100 or another gNB100).
[0035] Specifically, the encoding / decoding unit 250 decodes the data output from the modem unit 230 and concatenates the decoded data. In addition, the encoding / decoding unit 250 divides the data output from the data transmitter / receiver 260 into pieces of a predetermined size and performs coding on the divided data.
[0036] The data transmitter / receiver 260 assembles and disassembles data units (Protocol Data Units (PDUs) / Service Data Units (SDUs)) that make up data between each layer. The multiple layers include a Medium Access Control (MAC) layer, a Radio Link Control (RLC) layer, a Packet Data Convergence Protocol (PDCP) layer, etc. The data transmitter / receiver 260 also performs data error correction and retransmission control based on Hybrid Automatic Repeat Request (HARQ).
[0037] The control unit 270 controls the UE 200. The control unit 270 controls, for example, transmission and reception of radio signals by the radio signal transmission and reception unit 210, amplification by the amplifier unit 220, data modulation / demodulation by the modem unit 230, signal processing by the control signal and reference signal processing unit 240, coding / decoding by the encoding / decoding unit 250, and assembly / disassembly of data units by the data transmission and reception unit 260.
[0038] In the embodiment, the control unit 270 can assume that the position of the PUCCH resource for the Msg4 HARQ-ACK PUCCH is determined based on configuration information that configures the PUCCH resource for the Msg4 HARQ-ACK PUCCH. Specifically, when the configuration information is configuration information for SBFD, the control unit 270 can assume that the position of the PUCCH resource for the Msg4 HARQ-ACK PUCCH is determined based on the edge of the UL subband of the time unit to which SBFD is applied. Note that the edge of the UL subband may be interpreted as the lower or upper end of the UL subband in the frequency direction. Also, when the configuration information is configuration information for non-SBFD, the control unit 270 can assume that the position of the PUCCH resource for the Msg4 HARQ-ACK PUCCH is determined based on the edge of the band of the time unit to which non-SBFD is applied (i.e., the time unit to which TDD is applied). Note that the edge of the band of the time unit to which TDD is applied may be interpreted as the lower or upper end of the band in the frequency direction.
[0039] In the embodiment, the control unit 270 may assume that, when frequency hopping (FH) is applied to the Msg4 HARQ-ACK PUCCH, the position of the PUCCH resource for the Msg4 HARQ-ACK PUCCH is determined based on the edge of the UL subband and the resource width of the UL subband. Note that the resource width of the UL subband may be interpreted as the BWP size of the UL subband (the size from the lower end to the upper end of the UL subband).
[0040] Control unit 270 of the embodiment may assume that FH is not applied to the Msg4 HARQ-ACK PUCCH. A method for determining the position of the PUCCH resource for the Msg4 HARQ-ACK PUCCH in this case will be described in "(4.2) Example of Operation."
[0041] In the embodiment, the control unit 270 may assume that the location of the PUCCH resource for the Msg4 HARQ-ACK PUCCH is determined by an offset from the edge of the UL subband. In this case, the amount of the offset may be determined based on the resource width of the UL subband. This offset may be interpreted as a PRB offset.
[0042] (2.2) Base station functional block configuration As shown in FIG. 5, the gNB 100 includes a radio signal transceiver unit 110 and a control unit 120.
[0043] The radio signal transmitting / receiving unit 110 transmits and receives radio signals to and from the UE 200. The radio signal transmitting / receiving unit 110 may be configured with a transmitting unit that transmits radio signals to the UE 200 and a receiving unit that receives radio signals from the UE 200. The radio signals may include data or may be interpreted as data. Transmission may be interpreted as configuration, instruction, notification, etc. Reception may be interpreted as (reported), notification, etc. Note that configuration may be realized by configuration information (information element (IE)) of a radio resource control (RRC) layer, and instruction may be realized by a control element (CE) or downlink control information (DCI) of a medium access control (MAC) layer.
[0044] The wireless signal transmitting / receiving unit 110 can receive information transmitted by the above-described wireless signal transmitting / receiving unit 210. In addition, the wireless signal transmitting / receiving unit 110 can transmit information received by the above-described wireless signal transmitting / receiving unit 210.
[0045] The control unit 120 controls the gNB 100. For example, the control unit 120 controls the transmission and reception of radio signals by the radio signal transmission and reception unit 110. Furthermore, the control unit 120 can control itself by assuming the operation of the UE 200.
[0046] The control unit 120 according to the embodiment can configure the PUCCH resource for the Msg4 HARQ-ACK PUCCH in the UE 200. Specifically, the control unit 120 causes the radio signal transmitting / receiving unit 110 to transmit the above-described configuration information. Details of the configuration information will be described in the section "(4.2) Example of Operation."
[0047] (3)SBFD SBFD is a type of (full-duplex) duplexing scheme based on time division duplexing (TDD), enabling simultaneous use of multiple sub-bands that make up the TDD band. SBFD can be considered a duplexing scheme in which multiple sub-bands are set within the TDD band, or a duplexing scheme in which DL and UL are assigned non-overlapping in the frequency direction within a TDD time unit (e.g., symbol).
[0048] A symbol to which SBFD is applied is also referred to as an SBFD symbol. "SBFD is applied" may be interpreted as SBFD being applied to at least a part of the scheduling. In other words, a "symbol to which SBFD is applied" may be interpreted as a symbol to which SBFD is applied (SBFD symbol) in scheduling to which SBFD is applied. Furthermore, a "symbol to which non-SBFD is applied" may be interpreted as a symbol to which SBFD is not applied (non-SBFD symbol) in scheduling to which SBFD is applied. Note that time units (e.g., symbols) in the present disclosure may be interpreted as other time units. For example, an SBFD symbol may be interpreted as an SBFD slot, or vice versa.
[0049] As shown in FIG. 6, DL or UL is assigned to subbands (SBFD subbands) constituting an SBFD symbol. Hereinafter, a subband to which DL is assigned is also referred to as a DL subband, and a subband to which UL is assigned is also referred to as a UL subband. Also, a DL / UL subband in an active DL / UL BWP is also referred to as a DL / UL usable PRB. Note that if a UE-specific configuration is not supported for the frequency location of the SBFD subband, a DL / UL usable PRB may be determined as one that satisfies both the cell-specific DL / UL subband and the DL / UL BWP in the SBFD symbol.
[0050] Below, we will briefly explain the terms related to SBFD. SBFD symbol: Symbol to which SBFD sub-band is set Non-SBFD symbol: Symbol for which SBFD sub-band is not set DL (or semi-static D) symbol: A symbol designated DL by TDD-UL-DL-Configuration Common and / or TDD-UL-DL-Configuration Dedicated. UL (or semi-static U) symbol: A symbol designated by UL by TDD-UL-DL-Configuration Common and / or TDD-UL-DL-Configuration Dedicated. FL (or semi-static F, or flexible) symbol: A symbol designated as flexible (FL) by TDD-UL-DL-ConfigurationCommon and / or TDD-UL-DL-ConfigurationDedicated. SBFD DL symbol: A symbol indicated in DL by tdd-UL-DL-Configuration Common or tdd-UL-DL-Configuration Dedicated, in which an SBFD subband is configured SBFD FL symbol: A symbol indicated flexibly (FL) by the tdd-UL-DL-Configuration Common or tdd-UL-DL-Configuration Dedicated, in which the SBFD subband is configured.
[0051] (4) Operation of the wireless communication system (4.1) Issues Figure 7 is a table (Table 9.2.1-1) shown in 3GPP TS 38.213, section 9.2.1, which is a table for determining PUCCH resources before dedicated PUCCH resources are configured. When TDD is applied to resource allocation, the PUCCH resource for Msg4 HARQ-ACK PUCCH in RA is determined according to this table. That is, the PUCCH format, start symbol, number of symbols (duration), PRB offset (RB BWP offset ), and the set of Cyclic Shift index (CS index) was determined according to this table. BWP sizeindicates the UL BWP size of a non-SBFD symbol (UL symbol). Furthermore, when FR2-2 is applied, the number of PRBs can be set by nrofPRBs included in pucch-ConfigCommon.
[0052] The position (starting PRB) of the PUCCH resource for the Msg4 HARQ-ACK PUCCH is determined according to the PRB offset shown in Table 9.2.1-1 so as to fit within the UL BWP size of a non-SBFD symbol (UL symbol) to which TDD is applied. However, when SBFD is applied to resource allocation, if the starting PRB of the PUCCH resource is determined according to the PRB offset shown in Table 9.2.1-1, there is a risk that the PUCCH resource will be configured outside the UL subband (i.e., the DL subband) even if it is within the BWP size of the SBFD symbol. Furthermore, under such an assumption, the UE may transmit the Msg4 HARQ-ACK PUCCH outside the UL subband.
[0053] Furthermore, frequency hopping (FH) has always been applicable when transmitting the Msg4 HARQ-ACK PUCCH. Similarly, in this case, the starting PRBs of the second hop (PUCCH resource after hopping) and the first hop (PUCCH resource before hopping) of the Msg4 HARQ-ACK PUCCH are determined according to the PRB offset shown in FIG. 7 so as to fit within the UL BWP size of the non-SBFD symbol (UL symbol) to which TDD is applied. However, when SBFD is applied to resource allocation, if the starting PRBs of the second hop and the first hop of the Msg4 HARQ-ACK PUCCH are determined according to the PRB offset shown in FIG. 7, there is a risk that the PUCCH resource will be set outside the UL subband (i.e., the DL subband) even if it is within the BWP size of the SBFD symbol. Furthermore, under such an assumption, the UE may transmit the Msg4 HARQ-ACK PUCCH outside the UL subband.
[0054] Furthermore, when SBFD is applied to resource allocation, it is possible that FH cannot be applied to the Msg4 HARQ-ACK PUCCH. In such a case, there is room for consideration on a method of making FH inapplicable or a method of determining the PUCCH resource position (starting PRB).
[0055] (4.2) Example of operation (4.2.1) Example 1 First, operation example 1 will be described. In operation example 1, in order to configure PUCCH resources for Msg4 HARQ-ACK PUCCH, configuration for SBFD is used in addition to conventional configuration for non-SBFD. The configuration for non-SBFD may be pucch-ResourceCommon and / or nrofPRBs included in pucch-ConfigCommon. pucch-ConfigCommon is an information element (IE) that configures parameters related to PUCCH. pucch-ResourceCommon is an IE that configures PUCCH resources in RA. nrofPRBs is an IE that configures the number of PRBs for each PUCCH resource. Note that IEs in the present disclosure may be interpreted as RRC IEs.
[0056] In operation example 1, the configuration for SBFD is the same as the configuration for non-SBFD, except that it is applied to SBFD symbols. To distinguish between the two, the configuration for SBFD may be called pucch-ResourceCommon for SBFD and / or nrofPRBs for SBFD. pucch-ResourceCommon for SBFD and / or nrofPRBs for SBFD may be included in pucch-ConfigCommon, just like pucch-ResourceCommon and / or nrofPRBs. The configuration for non-SBFD may be called pucch-ResourceCommon for non-SBFD and / or nrofPRBs for non-SBFD, but below it will be called pucch-ResourceCommon and / or nrofPRBs to match the conventional names.
[0057] As a result, the PUCCH resource for the Msg4 HARQ-ACK PUCCH may be configured as shown below.
[0058] When transmitting the Msg4 HARQ-ACK PUCCH in an SBFD slot (all symbols in the slot are SBFD symbols), the PUCCH resource for the Msg4 HARQ-ACK PUCCH may be determined by the pucch-ResourceCommon for SBFD. When transmitting the Msg4 HARQ-ACK PUCCH in a non-SBFD slot (all symbols in the slot are non-SBFD symbols), the PUCCH resource for the Msg4 HARQ-ACK PUCCH may be determined by the pucch-ResourceCommon. When transmitting Msg4 HARQ-ACK PUCCH in a slot that includes both SBFD symbols and non-SBFD symbols, whether to apply the above pucch-ResourceCommon for SBFD or the above pucch-ResourceCommon to determine the PUCCH resource for Msg4 HARQ-ACK PUCCH may be determined by Alt1 or Alt2 below. Alt1: Defined in the specification. For example, only one of the above pucch-ResourceCommon for SBFD or the above pucch-ResourceCommon is always applied to determine the PUCCH resource for Msg4 HARQ-ACK PUCCH. Alt2: Determined according to the symbol type of the first / last symbol of the slot. For example, if the first / last symbol of the slot is an SBFD symbol, the PUCCH resource for Msg4 HARQ-ACK PUCCH is determined by applying the above pucch-ResourceCommon for SBFD. On the other hand, if the first / last symbol of the slot is a non-SBFD symbol, the PUCCH resource for Msg4 HARQ-ACK PUCCH is determined by applying the above pucch-ResourceCommo.
[0059] When setting the number of PRBs for PUCCH transmission in SBFD symbols, nrofPRBs for SBFD may be applied. If nrofPRBs for SBFD is not set, OptA or OptB below may be adopted. · OptA: The specified value (e.g., 1) may be applied as the number of PRBs. · OptB: (used to set the number of PRBs for PUCCH transmission in non-SBFD symbols) nrofPRBs may be applied.
[0060] As described above, in operation example 1, when configuring PUCCH resources for Msg4 HARQ-ACK PUCCH, a new configuration for SBFD can be used in addition to the existing configuration for non-SBFD. This makes it possible to configure PUCCH resources for Msg4 HARQ-ACK PUCCH separately for non-SBFD and SBFD.
[0061] (4.2.2) Example 2 Operation example 2 will be described with reference to Figure 8. In operation example 2, when transmitting Msg4 HARQ-ACK PUCCH in an SBFD symbol, PUCCH resources are configured in accordance with the definition of a new specification or via a system information block (SIB). That is, in operation example 2, instead of following Table 9.2.1-1 (see Figure 7) shown in 3GPP TS 38.213, section 9.2.1, the PRB offset value in the PUCCH resource configuration is configured according to the table of Figure 8 or according to new parameters included in pucch-ConfigCommon. Note that in the table of Figure 7 or Figure 8, each entry indicated by an index in the table is specified by pucch-ResourceCommon included in pucch-ConfigCommon. This makes it possible to configure the PUCCH resource for Msg4 HARQ-ACK PUCCH according to the table of Figure 7 or Figure 8.
[0062] <Option 1> First, a case where PUCCH resources for Msg4 HARQ-ACK PUCCH are configured in accordance with the definition of the new specification (see FIG. 8) will be described. The table shown in FIG. 8 is the same as the table shown in FIG. 7 except for the PRB offset in the row of Index 15. Specifically, the PRB offset in the row of Index 15 in FIG. 7 is set based on the UL BWP size (N BWP size ) divided into four (N BWP size / 4), but the PRB offset in the row of Index 15 in the table shown in Figure 8 is the BWP size of the UL subband of the SBFD symbol (N in the figure). UL_SB size ) divided into four (N UL_SB size / 4). Note that N UL_SB size may indicate the BWP size of the UL subband, or may indicate the size of UL usable PRBs of the initial UL BWP.
[0063] In the second operational example, the table in Fig. 8 can be used. For example, when index 15 in the table is specified to transmit the Msg4 HARQ-ACK PUCCH in the SBFD symbol, N is set as the PRB offset in the PUCCH resource configuration. UL_SB size / 4 is used.
[0064] <Option 2> Next, a case where a PUCCH resource for an Msg4 HARQ-ACK PUCCH is configured via an SIB will be described. In this case, the PRB offset in the row of Index 15 in the table shown in FIG. 7 is set / instructed to an arbitrary value by a new parameter included in the SIB (for example, a new parameter included in pucch-ConfigCommon). The new parameter may be, for example, an IE called prb-offset-sbfd-r19, or may be set in pucch-ConfigCommon. Note that the arbitrary value may be a value that is freely determined (there may be a lower or upper limit for the value), or may be a value selected from several candidate values.
[0065] For example, referring to the table of Figure 7, when Index 15 in the table is specified to transmit Msg4 HARQ-ACK PUCCH in the SBFD symbol, the value set by the new parameters is used as the PRB offset in the configuration of the PUCCH resource set by the new parameters.
[0066] As a modified example when using SIB (new parameter), the PRB offsets in the other rows of indexes 0 to 14 in the table of FIG. 7 may also be set / instructed to any value.
[0067] As described above, in operation example 2, a new PRB offset for SBFD can be used when configuring PUCCH resources for Msg4 HARQ-ACK PUCCH. This makes it possible to use a PRB offset suitable for the BWP size of the UL subband, especially when the above-mentioned Index 15 is specified.
[0068] (4.2.3) Example 3 Operation example 3 will be described with reference to Figures 9 to 13. Operation example 3 is for extending the position (starting PRB) of a PUCCH resource when configuring and transmitting an Msg4 HARQ-ACK PUCCH in an SBFD symbol. Note that the "position (starting PRB)" here refers to a position in the frequency direction. The starting PRB of a PUCCH resource is determined by a PRB offset.
[0069] The PRB offset indicates the location of a resource from a reference position in the frequency direction (for example, the bottom end of the BWP). The reference position may be the top end of the BWP, and whether the top or bottom end is the reference position may be indicated by pucch-ConfigCommon. The "bottom end of the BWP" may be interpreted as the bottom end of the BWP in the frequency direction. The "top end of the BWP" may be interpreted as the top end of the BWP in the frequency direction.
[0070] In operation example 3, frequency hopping (FH) is applied to the Msg4 HARQ-ACK PUCCH. In Figures 9 to 12, the PUCCH resource before hopping is indicated as 1st hop, and the PUCCH resource after hopping is indicated as 2nd hop. Note that FH in operation example 3 is assumed to be intra-slot hopping. Also, Figures 9 to 12 show an SBFD slot in which a UL subband is set in the middle in the frequency direction. The areas outside the UL subband are assumed to be DL subbands.
[0071] <Option 1> First, referring to FIGS. 9 and 10, the PRB offset (RB BWP offset ) will be described. That is, the case where the reference position to which the PRB offset is applied is the edge of the BWP (hereinafter, the lower edge of the BWP) will be described.
[0072] As shown in Figure 9, r PUCCH When is 0 to 7, the lowest PRB index of the PUCCH resource of the 1st hop is expressed by the following equation (1): Similarly, the lowest PRB index of the PUCCH resource of the 2nd hop is expressed by the following equation (2):
number
number
[0073] Also, as shown in Figure 10, r PUCCH When is 8 to 15, the lowest PRB index of the PUCCH resource of the 2nd hop is expressed by the following equation (3): Similarly, the lowest PRB index of the PUCCH resource of the 1st hop is expressed by the following equation (4).
number
number
[0074] In Figures 9 and 10, equations (1) to (4), N UL_SB size indicates the resource width (BWP size) of the UL subband. UL_SB start indicates the position of the UL subband (starting PRB). UL_SB start may indicate the position of the UL usable PRBs of the initial BWP (start PRB). UL_SB start indicates the start PRB relative to the edge of the SBFD slot, and therefore may be interpreted as indicating the resource width outside the UL subband (i.e., the DL subband). UL_SB size +2*RB UL_SB start is the resource width of the entire SBFD slot, N UL_SB size In addition, in equations (1) to (4), N RB is the number of PRBs, N CS indicates the number of CSs, respectively.
[0075] <Option 2> First, referring to FIGS. 11 and 12, the PRB offset (RB BWP offset ) will be described. That is, the case where the reference position to which the PRB offset is applied is set to the edge of the UL subband (hereinafter, the lower edge of the UL subband) will be described.
[0076] Here, the UL subband may be interpreted as the UL usable PRBs in the initial BWP, the edge of the UL subband may be interpreted as the position (starting PRB) of the UL subband, and the new interpretation of the PRB offset may be interpreted as a reinterpretation of the PRB offset.
[0077] As shown in Figure 11, r PUCCHWhen is 0 to 7, the lowest PRB index of the PUCCH resource of the 1st hop is expressed by the following equation (5): Similarly, the lowest PRB index of the PUCCH resource of the 2nd hop is expressed by the following equation (6).
number
number
[0078] Also, as shown in Figure 12, r PUCCH When is 8 to 15, the lowest PRB index of the PUCCH resource of the 2nd hop is expressed by the following equation (7): Similarly, the lowest PRB index of the PUCCH resource of the 1st hop is expressed by the following equation (8).
number
number
[0079] The explanation of formulas (5) to (8) is almost the same as the explanation of formulas (1) to (4), so please refer to that explanation.
[0080] Finally, a specific sequence of Option 2 will be described with reference to Figure 13. First, UE 200 receives configuration information regarding PUCCH resources for Msg4 HARQ-ACK PUCCH for SBFD from gNB 100. Next, based on this configuration information, UE 200 assumes that the PRB offset used in determining the position of the PUCCH resource is based on the edge of the UL subband. This allows UE 200 to transmit the PUCCH within the UL subband.
[0081] As described above, in operation example 3, even when SBFD is applied, the position of the PUCCH resource for the Msg4 HARQ-ACK PUCCH can be determined by flexibly interpreting the PRB offset. As a result, particularly when the interpretation of option 2 is applied, the PRB offset is determined based on the UL subband, so that the Msg4 HARQ-ACK PUCCH can be reliably transmitted within the UL subband. Furthermore, in this operation example, FH can be applied to SBFD slots as well as non-SBFD slots, so that the PUCCH resource for the Msg4 HARQ-ACK PUCCH can be allocated more flexibly.
[0082] (4.2.4) Example 4 Operation example 4 will be described with reference to Figures 14 to 17. In operation example 4, when SBFD is applied, it is possible to select not to apply FH to Msg4 HARQ-ACK PUCCH. Furthermore, operation example 4 determines the PUCCH resource for Msg4 HARQ-ACK PUCCH when FH cannot be applied. Note that FH in operation example 4 is assumed to be intra-slot hopping. Also, Figures 14 to 17 show an SBFD slot in which a UL subband is set in the middle in the frequency direction. The outside of the UL subband is assumed to be a DL subband.
[0083] Whether FH is not applicable to the Msg4 HARQ-ACK PUCCH in the SBFD symbol may be determined by one of the following. Alt1: Defined by the specification, i.e. FH is always disabled. Example: FH for Msg4 HARQ-ACK PUCCH is disabled by the specification. ·Alt2: Set or directed by SIB. For example, a new parameter in pucch-ConfigCommon (which may be, for example, an IE named intra-SlotFH-sbfd-r19) may indicate whether FH for Msg4 HARQ-ACK PUCCH is not applicable.
[0084] When FH cannot be applied to the Msg4 HARQ-ACK PUCCH in the SBFD symbol, the position of the PUCCH resource (starting PRB) of the Msg4 HARQ-ACK PUCCH may be determined according to one of the following options. The following options will be explained using equations (9) to (24), but for an explanation of these equations, please basically refer to the explanation of equations (1) to (4) in operation example 3. Note that the following options will be explained from the perspective of how the PRB offset that determines the position of the PUCCH resource is interpreted.
[0085] (Option 1) As shown in Fig. 14, the PRB offset is based on the lower edge of the UL BWP. In this case, the position of the PUCCH resource (start PRB) is expressed by the following equation (9) or (10).
number
number
[0086] As a variation of Option 1, an additional PRB offset (RB 1) is used to determine the PUCCH resource position (starting PRB). BWP offset-add ) may be applied. In this case, the position of the PUCCH resource (start PRB) is shown by the following equation (11) or (12). BWP offset-add or RB BWP offset-add N RBmay be set or indicated by the SIB. Note that this additional PRB offset may be, for example, an IE named additionalPRBOffset-sbfd to distinguish it from the additional PRB offset applied to the RedCap UE.
number
number
[0087] (Option 2) As shown in Figure 15, the PRB offset is based on the lower edge of the UL subband (or UL usable PRBs of the initial BWP). In this case, the position of the PUCCH resource (starting PRB) is expressed by the following equation (13) or (14).
number
number
[0088] As a variation of Option 2, when determining the position of the PUCCH resource (starting PRB), an additional PRB offset (RB BWP offset-add ) may be applied. In this case, the position of the PUCCH resource (start PRB) is shown by the following equation (15) or (16). BWP offset-add or RB BWP offset-add N RB may be set or dictated by the SIB.
number
number
[0089] (Option 3) As shown in Fig. 16, the PRB offset is based on the upper edge of the UL BWP. In this case, the position of the PUCCH resource (start PRB) is expressed by the following equation (17) or (18).

[0090] As a variation of Option 3, when determining the position of the PUCCH resource (starting PRB), an additional PRB offset (RB BWP offset-add ) may be applied.

[0091] (Option 4) As shown in Figure 17, the PRB offset is based on the upper edge of the UL subband (or UL usable PRBs of the initial BWP). In this case, the position of the PUCCH resource (starting PRB) is expressed by the following equation (21) or (22).
number

[0092] As a variation of Option 4, when determining the position of the PUCCH resource (starting PRB), an additional PRB offset (RB BWP offset-add ) may be applied. In this case, the position of the PUCCH resource (start PRB) is shown by the following equation (23) or (24). BWP offset-add or RB BWP offset-add N RB may be set or dictated by the SIB.
number
number
[0093] Also, which option applies may be defined in the specification or may be set or indicated by the SIB.
[0094] For the specific sequences of options 2 and 4 in this operation example, please refer to the specific sequence of option 2 in operation example 3, as it is almost the same as that.
[0095] As described above, in operation example 4, it is possible to select whether FH is applicable to the Msg4 HARQ-ACK PUCCH in the SBFD symbol. Furthermore, even when FH is not applicable, the position of the PUCCH resource for the Msg4 HARQ-ACK PUCCH can be determined by flexibly interpreting the PRB offset. As a result, particularly when the interpretations of option 2 and option 4 are applied, the PRB offset is determined based on the UL subband, so that the Msg4 HARQ-ACK PUCCH can be transmitted reliably within the UL subband. Furthermore, in this operation example, an additional PRB offset can be applied, so that the PUCCH resource for the Msg4 HARQ-ACK PUCCH can be reliably allocated even when the available UL resources are narrow, as in the case of the SBFD symbol.
[0096] (5) Actions and Effects According to the above-described embodiment, even when SBFD is applied to resource allocation, UE200 can appropriately configure the PUCCH resource for the Msg4 HARQ-ACK PUCCH and transmit the Msg4 HARQ-ACK PUCCH in the UL subband of the SBFD symbol.

Furthermore, when the lower end or the upper end of the UL subband is specified as the reference position of the PRB offset, the UE 200 may interpret the PRB offset as described in option 2 of operation example 3.

Furthermore, the method for realizing each functional block is not particularly limited. That is, each functional block may be realized using a single device that is physically or logically coupled, or may be realized using two or more physically or logically separated devices that are directly or indirectly connected (for example, using wires, wirelessly, etc.) and these multiple devices. The functional block may also be realized by combining the single device or multiple devices with software.

[0142] 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.
[0143] A base station can accommodate one or more (e.g., three) cells (also called sectors). When a base station accommodates multiple cells, the entire coverage area of the base station can be divided into multiple smaller areas, and each smaller area can be provided with communication service by a base station subsystem (e.g., a small indoor base station (Remote Radio Head, RRH)). The term "cell" or "sector" refers to a part or the entire coverage area of a base station and / or a base station subsystem that provides communication service within this coverage.
[0144] In the present disclosure, the base station transmitting information to a terminal may be interpreted as the base station instructing the terminal to control or operate based on the information.
[0145] In this disclosure, terms such as "terminal," "user terminal," "Mobile Station (MS)," and "User Equipment (UE)" may be used interchangeably.
[0146] 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.
[0147] At least one of the base station and the mobile station may be referred to as a transmitting device, a receiving device, a communication device, etc. At least one of the base station and the mobile station may be a device mounted on a mobile object, the mobile object itself, etc. The mobile object refers to a movable object, and may move at any speed. Naturally, this also includes cases where the mobile object is stationary. Examples of the mobile object include, but are not limited to, vehicles, transport vehicles, automobiles, motorcycles, bicycles, connected cars, excavators, bulldozers, wheel loaders, dump trucks, forklifts, trains, buses, handcars, rickshaws, ships and other watercraft, airplanes, rockets, satellites, drones (registered trademark), multicopters, quadcopters, balloons, and objects mounted thereon. The mobile object may also be an autonomous mobile object operating based on an operational command. It may be a vehicle (e.g., a car, an airplane, etc.), an unmanned mobile object (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 be a device that does not necessarily move during communication operations. For example, at least one of the base station and the mobile station may be an Internet of Things (IoT) device such as a sensor.
[0148] Furthermore, a base station in the present disclosure may be read as a terminal. For example, the aspects / embodiments of the present disclosure may be applied to a configuration in which communication between a base station and a terminal is replaced with communication between multiple terminals (which may be called, for example, Device-to-Device (D2D) or Vehicle-to-Everything (V2X)). In this case, the terminal 200 may be configured to have the functions of the base station 100 described above. 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 an uplink channel and a downlink channel may be read as a side channel.
[0149] Similarly, the term "terminal" in the present disclosure may be read as "base station." In this case, the base station 100 may be configured to have the functions of the terminal 200 described above.
[0150] Fig. 19 shows an example of the configuration of a vehicle 2001. As shown in Fig. 19, the vehicle 2001 includes a drive unit 2002, a steering unit 2003, an accelerator pedal 2004, a brake pedal 2005, a shift lever 2006, left and right front wheels 2007, left and right rear wheels 2008, an axle 2009, an electronic control unit 2010, various sensors 2021 to 2029, an information service unit 2012, and a communication module 2013.

The information service unit 2012 uses information acquired from external devices via the communication module 2013, etc., to provide various multimedia information and multimedia services to the occupants of the vehicle 2001.
[0156] The information service unit 2012 may include input devices (e.g., keyboards, mice, microphones, switches, buttons, sensors, touch panels, etc.) that accept input from the outside, and may also include output devices (e.g., displays, speakers, LED lamps, touch panels, etc.) that output to the outside.
[0157] The driving assistance system unit 2030 is composed of various devices that provide functions for preventing accidents and reducing the driver's driving burden, such as millimeter-wave radar, Light Detection and Ranging (LiDAR), cameras, positioning locators (e.g., GNSS, etc.), map information (e.g., high-definition (HD) maps, autonomous vehicle (AV) maps, etc.), gyro systems (e.g., inertial measurement units (IMUs), inertial navigation systems (INSs), etc.), artificial intelligence (AI) chips, and AI processors, as well as one or more ECUs that control these devices. The driving assistance system unit 2030 also transmits and receives various information via the communication module 2013 to realize driving assistance functions or autonomous driving functions.
[0158] The communication module 2013 can communicate with the microprocessor 2031 and components of the vehicle 2001 via the communication port. For example, the communication module 2013 transmits and receives data via the communication port 2033 to and from a drive unit 2002, a steering unit 2003, an accelerator pedal 2004, a brake pedal 2005, a shift lever 2006, left and right front wheels 2007, left and right rear wheels 2008, an axle 2009, a microprocessor 2031 and memory (ROM, RAM) 2032 in the electronic control unit 2010, and sensors 2021 to 2029, which are provided in the vehicle 2001.
[0159] The communication module 2013 is a communication device that can be controlled by the microprocessor 2031 of the electronic control unit 2010 and can communicate with an external device. For example, it transmits and receives various information to and from the external device via wireless communication. The communication module 2013 may be located either inside or outside the electronic control unit 2010. The external device may be, for example, a base station, a mobile station, or the like.
[0160] The communication module 2013 may transmit at least one of signals from the above-mentioned various sensors 2021-2029 input to the electronic control unit 2010, information obtained based on the signals, and information based on input from the outside (user) obtained via the information service unit 2012 to an external device via wireless communication. The electronic control unit 2010, the various sensors 2021-2029, the information service unit 2012, etc. may be referred to as input units that accept input. For example, the PUSCH transmitted by the communication module 2013 may include information based on the above-mentioned input.
[0161] The communication module 2013 receives various information (traffic information, traffic signal information, vehicle distance information, etc.) transmitted from external devices and displays it on the information service unit 2012 provided in the vehicle. The information service unit 2012 may also be called an output unit that outputs information (for example, outputs information to a device such as a display or speaker based on the PDSCH received by the communication module 2013 (or data / information decoded from the PDSCH)).
[0162] Furthermore, the communication module 2013 stores various information received from external devices in a memory 2032 that can be used by the microprocessor 2031.

[0163] 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), and ascertaining, all of which are considered to be "judging" and "determining." "Determining" and "determining" may also include receiving (e.g., receiving information), transmitting (e.g., sending information), input, output, and accessing (e.g., accessing data in memory), all of which are considered to be "judging" and "determining." 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.
[0164] 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.
[0165] The reference signal may also be abbreviated as RS, and may be called a pilot depending on the applicable standard.
[0166] 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."
[0167] As used in this disclosure, any reference to an element using a designation such as "first," "second," etc. does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Thus, a reference to a first and a second element does not imply that only two elements may be employed or that the first element must in some way precede the second element.
[0168] The "means" in the configuration of each of the above devices may be replaced with "part," "circuit," "device," etc.
[0169] 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.
[0170] A radio frame may be composed of one or more frames in the time domain. Each of the one or more frames in the time domain may be called a subframe. A subframe may further be composed of one or more slots in the time domain. A subframe may have a fixed time length (e.g., 1 ms) that is independent of numerology.
[0171] 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.
[0172] 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.
[0173] 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.
[0174] 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.
[0175] 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 the existing LTE, a period shorter than 1 ms (for example, 1 to 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.
[0176] 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 terminal) to each terminal in TTI units. However, the definition of TTI is not limited to this.
[0177] 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.
[0178] 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.
[0179] A TTI having a time length of 1 ms may be called a regular TTI (TTI in LTE Rel. 8 to 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.
[0180] 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.
[0181] A resource block (RB) is a resource allocation unit in the time domain and frequency domain, and may include one or more consecutive subcarriers in the frequency domain. The number of subcarriers included in an RB may be the same regardless of numerology, for example, 12. The number of subcarriers included in an RB may also be determined based on numerology.
[0182] 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.
[0183] 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.
[0184] 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. 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.
[0185] 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.
[0186] 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."
[0187] 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 variously changed.
[0188] The "maximum transmit power" in this disclosure may mean the maximum value of transmit power, the nominal UE maximum transmit power, or the rated UE maximum transmit power.
[0189] 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.
[0190] 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."
[0191] 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.
