Description

Terminals, wireless communication methods

[0001] This disclosure relates to a terminal and wireless communication method that support subband non-overlapping full duplex (SBFD).

[0002] The 3rd Generation Partnership Project (3GPP®) has standardized the 5th generation mobile communication system (also known as 5G, New Radio (NR), or Next Generation (NG)), and is also working on standardizing 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 downlink (DL) and uplink (UL) by utilizing multiple subbands that make up the band of time-division duplexing (TDD). Such a duplexing scheme is called subband non-overlapping full duplex (SBFD). Symbols to which SBFD is applied may also be called SBFD symbols. Furthermore, in SBFD symbols, the subband used for DL ​​may be called the DL subband, and the subband used for UL may be called the UL subband.

[0004] Furthermore, in Release 19, support for initial access (random access (RA)) in SBFD is being considered (Non-Patent Document 1). Specifically, extending the sending and receiving of messages in RA to SBFD symbols is being considered.

[0005] In RA, the terminal (hereinafter also referred to as User Equipment (UE)) sends and receives the following messages with the base station (hereinafter also referred to as gNodeB (gNB)). First, the UE sends a preamble in a valid random access opportunity (valid RO). Second, the UE receives a Random Access Response (RAR). Third, the UE sends Msg3 as an RRC connection request message. Fourth, UE200 receives Msg4 as a conflict resolution message. Finally, the UE sends a Hybrid Automatic Repeat Request (HARQ)-ACK in response to Msg4. This HARQ-ACK in response to Msg4 is also called Msg4 HARQ-ACK, Msg4 HARQ-ACK PUCCH, or PUCCH with HARQ-ACK.

[0006] “New WID: Evolution of NR duplex operation: Sub-band full duplex (SBFD)”, RP-234035, 3GPP TSG RAN Meeting #102, 3GPP, December 11-15, 2023

[0007] When time-division duplication (TDD) was applied to resource allocation, the PUCCH resource for Msg4 HARQ-ACK PUCCH in the RA was determined according to Table 9.2.1-1 (see Figure 7) shown in 3GPP TS 38.213, section 9.2.1. For example, the physical resource block (PRB) offset was determined according to this Table 9.2.1-1. Furthermore, when FR2-2 was applied, the number of PRBs could be configured by pucch-ConfigCommon.

[0008] The location (start PRB) of the PUCCH resource for 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 the non-SBFD symbol (UL symbol) to which TDD is applied. However, when SBFD is applied to resource allocation, attempting to determine the start PRB of the PUCCH resource according to the PRB offset shown in Table 9.2.1-1 could result in the PUCCH resource being set outside the UL subband (i.e., the DL subband), even if it is within the BWP size of the SBFD symbol. Furthermore, the UE could potentially transmit Msg4 HARQ-ACK PUCCH outside the UL subband under such assumptions.

[0009] Therefore, this disclosure aims to provide a terminal that, even when SBFD is applied to resource allocation, can properly configure the PUCCH resource for Msg4 HARQ-ACK PUCCH and transmit Msg4 HARQ-ACK PUCCH in the UL subband of the SBFD symbol.

[0010] One aspect of the disclosure is a terminal comprising: a receiving unit that receives configuration information for setting a resource for a physical uplink control channel related to initial access in 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 location of the resource is determined with respect to the edge of the uplink subband; and a transmitting unit that transmits the physical uplink control channel at the location of the resource.

[0011] One aspect of the disclosure is a wireless communication method performed by a terminal, which receives configuration information to set a resource for a physical uplink control channel related to initial access in an uplink subband among a plurality of subbands available in a time-division duplex band, assumes that the location of the resource is determined relative to the edge of the uplink subband based on the configuration information, and transmits the physical uplink control channel at the location of the resource.

[0013] The embodiments will be described below with reference to the drawings. Note that identical or similar reference numerals are used to denote the same functions and components, and their descriptions will be omitted as appropriate.

[0014] (1) Wireless communication system configuration The wireless communication system 10 shown in Diagram 1 is a wireless communication system that follows a method called 5G. On the other hand, wireless communication system 10 may also be a wireless communication system that follows a method called Beyond 5G, 5G Evolution, or 6G.

[0015] The wireless communication system 10 can support Massive Multiple-Input Multiple-Output (Massive MIMO) that generates a more directional beam by controlling wireless signals transmitted from a plurality of antenna elements, Carrier Aggregation (CA) that bundles and uses a plurality of Component Carriers (CCs), Dual Connectivity (DC) that enables simultaneous communication with two base stations, etc.

[0016] As shown in FIG. 1, the wireless communication system 10 includes a base station 100 (hereinafter also referred to as a gNodeB (gNB) 100) that constitutes 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 a plurality of 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. Also, the NG-RAN 20 and the CN may simply be expressed as "network".

[0017] The gNB 100 may be divided into a central unit (CU) connected to the network and controlling the connection with the UE 200, and a distributed unit (DU) connected to the UE 200. 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 gNB 100 may be divided into a CU-CP, a CU-UP, and a DU.

[0018] Also, the wireless communication system 10 may support multiple frequency ranges (FRs). That is, as shown in FIG. 2, it may support the following FRs: - FR1: 410 MHz to 7.125 GHz - FR2-1: 24.25 GHz to 52.6 GHz - FR2-2: Above 52.6 GHz to 71 GHz

[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. In FR2-1, an SCS of 60 or 120 kHz (240 kHz may also be used) and a BW of 50 to 400 MHz may be used.

[0020] In FR2-2, in order 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] Also, as shown in FIG. 3, one slot in the wireless communication system 10 is composed of 14 symbols. When this configuration is maintained, as the SCS increases (broadens), the symbol period (and slot period) becomes shorter. Note that the SCS is not limited to the frequencies shown in FIG. 3 and may be, for example, frequencies such as 480 kHz and 960 kHz.

[0022] Also, the number of symbols constituting one slot does not necessarily have to be 14 symbols and may be, for example, 28 or 56 symbols. Furthermore, the number of slots per subframe may vary depending on the SCS.

[0023] (2) Functional Block Configuration of the Wireless Communication System (2.1) Functional Block Configuration of the Terminal As shown in FIG. 4, the UE200 includes a wireless signal transceiver unit 210, an amplifier unit 220, a modulation / demodulation unit 230, a control signal / reference signal processing unit 240, an encoding / decoding unit 250, a data transceiver unit 260, and a control unit 270.

[0024] The wireless signal transceiver 210 transmits and receives wireless signals to and from the gNB 100. The wireless signal transceiver 210 may consist of a transmitting unit that transmits wireless signals to the gNB 100 and a receiving unit that receives wireless signals from the gNB 100. The wireless signal may include data or may be interpreted as data. Transmission may be interpreted as reporting, notifying, etc. Reception may be interpreted as setting, instructing, notifying, etc. Setting may be implemented by setting information (information element (IE)) of the wireless resource control (RRC) layer, and instruction may be implemented by control element (CE) or downlink control information (DCI) of the media access control (MAC) layer.

[0025] The wireless signal transceiver 210 of this embodiment can perform initial access (random access (RA)) to the gNB100. In the RA, the wireless signal transceiver 210 can transmit and receive the above-mentioned Msg1 to Msg4 and Msg4 HARQ-ACK PUCCH. Note that Msg4 HARQ-ACK PUCCH may be read as PUCCH related to initial access.

[0026] The wireless signal transceiver 210 of the embodiment can receive configuration information to set the PUCCH resource for Msg4 HARQ-ACK PUCCH. The configuration information may be configuration information for transmitting Msg4 HARQ-ACK PUCCH in SBFD symbols (configuration information for SBFD). The configuration information for SBFD may be understood as configuration information to set the PUCCH resource for Msg4 HARQ-ACK PUCCH in the UL subband, among the multiple subbands (DL subband and UL subband) available in the time division duplex (TDD) band. In this disclosure, the UL subband may be read as UL usable PRBs in the initial BWP.

[0027] Furthermore, the configuration information may also be the configuration information for transmitting Msg4 HARQ-ACK PUCCH in the non-SBFD symbol (non-SBFD configuration information). The non-SBFD configuration information may be understood as the non-SBFD configuration information for setting up a PUCCH resource in the TDD band where subbands are not available. In other words, the SBFD configuration information may be different from the non-SBFD configuration information.

[0028] The wireless signal transmission / reception unit 210 of this embodiment can transmit Msg4 HARQ-ACK PUCCH at the location of the PUCCH resource (start PRB) assumed by the control unit 270, which will be described later.

[0029] The amplifier section 220 consists of a Power Amplifier (PA) and a Low Noise Amplifier (LNA), among other components. The amplifier section 220 amplifies the wireless signal output from the wireless signal transmission / reception unit 210. The amplifier section 220 also amplifies the wireless signal output from the modulation / demodulation unit 230.

[0030] The modulation / demodulation unit 230 performs data modulation / demodulation, transmit power setting, and resource block allocation for each predetermined communication destination (gNB100 or other gNB100). CP-OFDM / DFT-S-OFDM may be applied in the modulation / demodulation unit 230. Furthermore, DFT-S-OFDM may be used not only for the uplink (UL) but also for the downlink (DL).

[0031] The control signal / reference signal processing unit 240 performs processing related to control signals transmitted to and from the gNB100, such as radio resource control (RRC) signaling.

[0032] The control signal / reference signal processing unit 240 performs processing on reference signals transmitted to and from the gNB100, such as the 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] Channels include control channels and data channels. Control channels include physical uplink control channels (PUCCH), physical downlink control channels (PDCCH), physical random access channels (PRACH), and physical broadcast channels (PBCH). Data channels include physical uplink sharing channels (PUSCH) and physical downlink sharing channels (PDSCH).

[0034] The encoding / decoding unit 250 performs data splitting / concatenation and coding / decoding for each predetermined communication destination (gNB100 or other gNB100).

[0035] Specifically, the encoding / decoding unit 250 decodes the data output from the modulation / demodulation unit 230 and concatenates the decoded data. The encoding / decoding unit 250 also divides the data output from the data transmission / reception unit 260 into predetermined sizes and performs coding on the divided data.

[0036] The data transmission / reception unit 260 performs assembly / decomposition of data units (Protocol Data Units (PDUs) / Service Data Units (SDUs)) that constitute the data between each layer. The multiple layers include the Media Access Control (MAC) layer, the Radio Link Control (RLC) layer, and the Packet Data Convergence Protocol (PDCP) layer. The data transmission / reception unit 260 also performs error correction and retransmission control of the data based on the Hybrid Automatic Repeat Request (HARQ).

[0037] The control unit 270 controls the UE200. For example, the control unit 270 controls the transmission and reception of wireless signals by the wireless signal transmission / reception unit 210, amplification by the amplifier unit 220, data modulation / demodulation by the modulation / demodulation unit 230, signal processing by the control signal / reference signal processing unit 240, coding / decoding by the encoding / decoding unit 250, and assembly / disassembly of data units by the data transmission / reception unit 260.

[0038] In this embodiment, the control unit 270 can be assumed to determine the position of the PUCCH resource of Msg4 HARQ-ACK PUCCH based on the setting information that sets the PUCCH resource of Msg4 HARQ-ACK PUCCH. Specifically, if the setting information is setting information for SBFD, the control unit 270 can be assumed to determine the position of the PUCCH resource of Msg4 HARQ-ACK PUCCH with respect to the edge of the UL subband in the time unit to which SBFD is applied. Note that the edge of the UL subband may be understood as the lower or upper edge of the UL subband in the frequency direction. Furthermore, if the setting information is setting information for non-SBFD, the control unit 270 can be assumed to determine the position of the PUCCH resource of Msg4 HARQ-ACK PUCCH with respect to the edge of the band in 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 in the time unit to which TDD is applied may be understood as the lower or upper edge of the band in the frequency direction.

[0039] In this embodiment, the control unit 270 may assume that when frequency hopping (FH) is applied to Msg4 HARQ-ACK PUCCH, the position of the PUCCH resource for Msg4 HARQ-ACK PUCCH is determined based on the edge of the UL subband and the resource width of the UL subband. The resource width of the UL subband may be understood as the BWP size of the UL subband (the size from the lower end to the upper end of the UL subband).

[0040] The control unit 270 in this embodiment may assume that FH is not applied to Msg4 HARQ-ACK PUCCH. The method for determining the location of the PUCCH resource for Msg4 HARQ-ACK PUCCH in this case will be explained in the section "(4.2) Operation Example".

[0041] The control unit 270 of the embodiment may assume that the location of the PUCCH resource of Msg4 HARQ-ACK PUCCH is determined by an offset from the edge of the UL subband. In this case, it may be assumed that the amount of the offset is determined based on the resource width of the UL subband. This offset may be understood to be a PRB offset.

[0042] (2.2) As shown in the functional block diagram 5 of the base station, the gNB100 comprises a radio signal transmitting and receiving unit 110 and a control unit 120.

[0043] The wireless signal transceiver 110 transmits and receives wireless signals to and from the UE 200. The wireless signal transceiver 110 may consist of a transmitting unit that transmits wireless signals to the UE 200 and a receiving unit that receives wireless signals from the UE 200. The wireless signal may include data, or may be interpreted as data. Transmission may be interpreted as setting, instruction, notification, etc. Reception may be interpreted as reporting, notifying, etc. Settings may be implemented by setting information (information elements (IE)) of the Wireless Resource Control (RRC) layer, and instructions may be implemented by control elements (CE) or downlink control information (DCI) of the Media Access Control (MAC) layer.

[0044] The wireless signal transmitting / receiving unit 110 can receive the information transmitted by the wireless signal transmitting / receiving unit 210 described above. Furthermore, the wireless signal transmitting / receiving unit 110 can transmit the information received by the wireless signal transmitting / receiving unit 210 described above.

[0045] The control unit 120 controls the gNB100. For example, the control unit 120 controls the transmission and reception of wireless signals by the wireless signal transmission / reception unit 110. Furthermore, the control unit 120 can control itself by anticipating the operation of the UE200.

[0046] The control unit 120 of this embodiment can set the PUCCH resource of Msg4 HARQ-ACK PUCCH to UE200. Specifically, the control unit 120 causes the wireless signal transmission / reception unit 110 to transmit the above-mentioned setting information. Details of the setting information will be explained in the section "(4.2) Operation Example".

[0047] (3) SBFD SBFD is a type of (full-duplex) duplexing system that is based on time-division duplexing (TDD), and enables the simultaneous use of multiple subbands that make up the TDD band. SBFD can also be described as a duplexing system in which multiple subbands are set up within the TDD band, or as a duplexing system in which DL and UL are assigned non-overlapping in the frequency direction within the TDD time unit (e.g., symbol).

[0048] Symbols to which SBFD applies are also called SBFD symbols. "SBFD applies" may be interpreted as SBFD being applied in at least part of the scheduling. That is, "symbols to which SBFD applies" may be interpreted as symbols to which SBFD applies in scheduling where SBFD is applied (SBFD symbols). Also, "symbols to which non-SBFD applies" may be interpreted as symbols to which SBFD does not apply in scheduling where SBFD is applied (non-SBFD symbols). Note that the time units (e.g., symbols) in this disclosure may be interpreted as other time units. For example, SBFD symbols may be interpreted as SBFD slots, and vice versa.

[0049] As shown in Figure 6, subbands constituting an SBFD symbol (SBFD subbands) are assigned either DL or UL. Hereafter, subbands assigned DL will also be referred to as DL subbands, and subbands assigned UL will also be referred to as UL subbands. Furthermore, DL / UL subbands within an active DL / UL BWP will also be referred to as DL / UL usable PRBs. Note that if UE-specific configuration is not supported for the frequency position of an SBFD subband, the DL / UL usable PRB may be determined to satisfy both the cell-specific DL / UL subband and the DL / UL BWP within the SBFD symbol.

[0050] The following provides a brief explanation of terms related to SBFD. • SBFD symbol: A symbol in which an SBFD subband is set. • Non-SBFD symbol: A symbol in which an SBFD subband is not set. • DL (or semi-static D) symbol: A symbol instructed to DL by TDD-UL-DL-ConfigurationCommon and / or TDD-UL-DL-ConfigurationDedicated. • UL (or semi-static U) symbol: A symbol instructed to UL by TDD-UL-DL-ConfigurationCommon and / or TDD-UL-DL-ConfigurationDedicated. • FL (or semi-static F, or flexible) symbol: A symbol flexibly (FL) instructed by TDD-UL-DL-ConfigurationCommon and / or TDD-UL-DL-ConfigurationDedicated. • SBFD DL symbol: A symbol instructed to DL by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated in which an SBFD subband is set. FL symbol: A symbol flexibly (FL) indicated by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, which is a symbol in which an SBFD subband is configured.

[0051] (4) Operation of the wireless communication system (4.1) Problem Figure 7 is a table (Table 9.2.1-1) shown in 3GPP TS 38.213, section 9.2.1, which determines the PUCCH resource before a dedicated PUCCH resource is set. When TDD is applied to resource allocation, the PUCCH resource for Msg4 HARQ-ACK PUCCH in RA was determined according to this table. That is, PUCCH format, start symbol, number of symbols (duration), PRB offset (RB) BWP offsetThe set of Cyclic Shift indexes (CS indexes) was determined according to this table. Note that N in the figure BWP size This indicates the UL BWP size of non-SBFD symbols (UL symbols). Furthermore, when FR2-2 is applied, the number of PRBs could be set by nrofPRBs included in pucch-ConfigCommon.

[0052] The location (start PRB) of the PUCCH resource for 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 the non-SBFD symbol (UL symbol) to which TDD is applied. However, when SBFD is applied to resource allocation, attempting to determine the start PRB of the PUCCH resource according to the PRB offset shown in Table 9.2.1-1 could result in the PUCCH resource being set outside the UL subband (i.e., the DL subband), even if it is within the BWP size of the SBFD symbol. Furthermore, the UE could potentially transmit Msg4 HARQ-ACK PUCCH outside the UL subband under such assumptions.

[0053] Furthermore, frequency hopping (FH) could always be applied when transmitting Msg4 HARQ-ACK PUCCH. In this case as well, the starting PRB for the 2nd hop (PUCCH resource after hopping) and 1st hop (PUCCH resource before hopping) of Msg4 HARQ-ACK PUCCH was determined according to the PRB offset shown in Figure 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 was applied to resource allocation, attempting to determine the starting PRB for the 2nd and 1st hops of Msg4 HARQ-ACK PUCCH according to the PRB offset shown in Figure 7 could result in the PUCCH resource being set outside the UL subband (i.e., the DL subband), even if it was within the BWP size of the SBFD symbol. Also, under such assumptions, the UE could transmit Msg4 HARQ-ACK PUCCH outside the UL subband.

[0054] Furthermore, if SBFD is applied to resource allocation, it may be possible to make FH unavailable for Msg4 HARQ-ACK PUCCH. In such cases, there was room for consideration regarding methods for disabling FH, or methods for determining the PUCCH resource location (start PRB).

[0055] (4.2) Operation Examples (4.2.1) Operation Example 1 First, Operation Example 1 will be described. Operation Example 1 uses SBFD settings in addition to the conventional non-SBFD settings to configure the PUCCH resource of Msg4 HARQ-ACK PUCCH. The non-SBFD settings may be pucch-ResourceCommon and / or nrofPRBs included in pucch-ConfigCommon. pucch-ConfigCommon is an information element (IE) that sets parameters related to PUCCH. pucch-ResourceCommon is an IE that sets the PUCCH resource in RA. nrofPRBs is an IE that sets the number of PRBs for each PUCCH resource. Note that IE in this disclosure may be read as RRC IE.

[0056] In Operation Example 1, the settings for SBFD are the same as those for non-SBFD, except that they are applied to SBFD symbols. To distinguish between the two, the settings 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, similar to pucch-ResourceCommon and / or nrofPRBs. The settings for non-SBFD may be called pucch-ResourceCommon for non-SBFD and / or nrofPRBs for non-SBFD, but below we will use the conventional terminology pucch-ResourceCommon and / or nrofPRBs.

[0057] This may result in the PUCCH resource for Msg4 HARQ-ACK PUCCH being configured as shown below.

[0058] - When sending Msg4 HARQ-ACK PUCCH in an SBFD slot (where all symbols in the slot are SBFD symbols), the PUCCH resource for Msg4 HARQ-ACK PUCCH may be determined by the above-mentioned pucch-ResourceCommon for SBFD. - When sending Msg4 HARQ-ACK PUCCH in a non-SBFD slot (where all symbols in the slot are non-SBFD symbols), the PUCCH resource for Msg4 HARQ-ACK PUCCH may be determined by the above-mentioned pucch-ResourceCommon. - When sending Msg4 HARQ-ACK PUCCH in a slot containing both SBFD and non-SBFD symbols, whether to apply the above-mentioned pucch-ResourceCommon for SBFD or the above-mentioned 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, the PUCCH resource for Msg4 HARQ-ACK PUCCH is determined by applying either the above pucch-ResourceCommon for SBFD or the above pucch-ResourceCommon. Alt2: Determined according to the symbol type of the first / last symbol in the slot. For example, if the first / last symbol in the slot is an SBFD symbol, the above pucch-ResourceCommon for SBFD is applied to determine the PUCCH resource for Msg4 HARQ-ACK PUCCH. On the other hand, if the first / last symbol in the slot is a non-SBFD symbol, the above pucch-ResourceCommo is applied to determine the PUCCH resource for Msg4 HARQ-ACK PUCCH.

[0059] When setting the number of PRBs for PUCCH transmissions in SBFD symbols, you may apply nrofPRBs for SBFD. If nrofPRBs for SBFD is not set, you may use either OptA or OptB below. OptA: You may apply a default value (e.g., 1) as the number of PRBs. OptB: You may apply nrofPRBs (used when setting the number of PRBs for PUCCH transmissions in non-SBFD symbols).

[0060] As described above, in Operation Example 1, when configuring the PUCCH resource for Msg4 HARQ-ACK PUCCH, a new SBFD configuration can be used in addition to the existing non-SBFD configuration. This allows the PUCCH resource for Msg4 HARQ-ACK PUCCH to be configured separately for non-SBFD and SBFD.

[0061] (4.2.2) Operation Example 2 Operation Example 2 will be explained with reference to Figure 8. Operation Example 2 is a method for setting the PUCCH resource when sending Msg4 HARQ-ACK PUCCH in an SBFD symbol, either according to the definition of the new specification or via the System Information Block (SIB). In other words, Operation Example 2 sets the value of the PRB offset in setting the PUCCH resource according to the table in Figure 8, or according to the new parameters included in pucch-ConfigCommon, instead of following Table 9.2.1-1 (see Figure 7) shown in 3GPP TS 38.213, section 9.2.1. Note that in the table in Figure 7 or Figure 8, each entry indicated by Index in the table is specified by pucch-ResourceCommon included in pucch-ConfigCommon. This makes it possible to set the PUCCH resource for Msg4 HARQ-ACK PUCCH according to the table in Figure 7 or Figure 8.

[0062] <Option 1> First, the case of setting the PUCCH resource of Msg4 HARQ-ACK PUCCH according to the definition of the new specification (see FIG. 8) will be described. The table shown in FIG. 8 is different from the table shown in FIG. 7 in the PRB offset of the row of Index 15, but is the same as the table shown in FIG. 7 otherwise. Specifically, the PRB offset of the row of Index 15 in FIG. 7 is the value obtained by dividing the UL BWP size (N BWP size ) of the non-SBFD symbol (UL symbol) by four (N BWP size / 4), while the PRB offset of the row of Index 15 in the table shown in FIG. 8 is the value obtained by dividing the BWP size of the UL sub-band of the SBFD symbol (N UL_SB size ) in the figure by four (N UL_SB size / 4). Note that N UL_SB size may indicate the BWP size of the UL sub-band or the size of the UL usable PRBs of the initial UL BWP.

[0063] In Operation Example 2, the table in FIG. 8 can be used. For example, when Index 15 in the table is specified to transmit Msg4 HARQ-ACK PUCCH in the SBFD symbol, N UL_SB size / 4 is used as the PRB offset in the setting of the PUCCH resource. [[ID=<Option 2> Next, we will describe the case where the PUCCH resource for Msg4 HARQ-ACK PUCCH is configured via SIB. In this case, the PRB offset in the row of Index 15 in the table shown in Figure 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 an IE such as prb-offset-sbfd-r19, or it may be set in pucch-ConfigCommon. Note that the arbitrary value may be a value that can be freely determined (there may be a lower or upper limit to the value), or it may be a value selected from several candidate values.

[0065] For example, referring to the table in Figure 7, if Index 15 in the table is specified to send Msg4 HARQ-ACK PUCCH in the SBFD symbol, the value set by the new parameter is used as the PRB offset in the PUCCH resource setting configured by the new parameter.

[0066] Furthermore, as a variation when using SIB (New Parameter), the PRB offsets for the other Index 0-14 rows in the table in Figure 7 may also be set / indicated to arbitrary values.

[0067] As described above, in Operation Example 2, a new PRB offset for SBFD can be used when configuring the PUCCH resource 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 Index 15 is specified as mentioned above.

[0068] (4.2.3) Operation Example 3 Operation Example 3 will be explained with reference to Figures 9 to 13. Operation Example 3 extends the position (start PRB) of the PUCCH resource when setting and transmitting Msg4 HARQ-ACK PUCCH in the SBFD symbol. Note that the "position (start PRB)" referred to here is the position in the frequency direction. The start PRB of the PUCCH resource is determined by the PRB offset.

[0069] The PRB offset indicates the position of the resource relative to a reference point in the frequency direction (e.g., the lower end of the BWP). The reference point may also be the upper end of the BWP, and the choice between the lower and upper ends may be indicated by pucch-ConfigCommon. Furthermore, the "lower end of the BWP" may be understood as the lower end of the BWP in the frequency direction, and the "upper end of the BWP" may be understood as the higher end of the BWP in the frequency direction.

[0070] In Operation Example 3, frequency hopping (FH) is applied to Msg4 HARQ-ACK PUCCH. In Figures 9 to 12, the PUCCH resource before hopping is shown as the 1st hop, and the PUCCH resource after hopping is shown as the 2nd hop. Note that the FH in Operation Example 3 is assumed to be intra-slot hopping. Also, Figures 9 to 12 show SBFD slots where the UL subband is set in the middle of the frequency direction. The area outside the UL subband is assumed to be the DL subband.

[0071] <Option 1> First, referring to Figures 9 and 10, PRB offset (RB BWP offset This section describes how to apply conventional rules or interpretations to the above. Specifically, it describes the case where the reference point to which the PRB offset is applied is the edge of the BWP (hereinafter, the lower edge of the BWP).

[0072] As shown in Figure 9, r PUCCH If the value is between 0 and 7, the lowest PRB index of the 1st hop PUCCH resource is given by the following equation (1). Similarly, the lowest PRB index of the 2nd hop PUCCH resource is given by the following equation (2).

[0073] Also, as shown in Figure 10, r PUCCHIf the value is between 8 and 15, the lowest PRB index of the 2nd hop PUCCH resource is given by equation (3) below. Similarly, the lowest PRB index of the 1st hop PUCCH resource is given by equation (4) below.

[0074] In Figures 9 and 10, and equations (1) to (4), N UL_SB size This indicates the resource width (BWP size) of the UL subband. RB UL_SB start This indicates the location of the UL subband (starting PRB). Also, RB UL_SB start This may indicate the location of the UL usable PRBs of the initial BWP (starting PRB). UL_SB start Since this indicates the starting PRB relative to the edge of the SBFD slot, it may be interpreted as indicating the resource width outside the UL subband (i.e., the DL subband). Therefore, N in equations (2) and (4) UL_SB size +2*RB UL_SB start N represents the total resource width of the SBFD slot. UL_SB size It becomes equal to . Note that in equations (1) to (4), N RB The number of PRBs is N CS The CS numbers are shown below.

[0075] <Option 2> First, referring to Figures 11 and 12, PRB offset (RB BWP offset This section describes when new rules or interpretations are applied to the following: Specifically, it describes when the reference position to which the PRB offset is applied is the edge of the UL subband (hereinafter, the lower edge of the UL subband).

[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 of the UL subband (starting PRB). Also, the new interpretation of the PRB offset may be interpreted as a reinterpretation of the PRB offset.

[0077] As shown in Figure 11, r PUCCH If the value is between 0 and 7, the lowest PRB index of the 1st hop PUCCH resource is given by the following equation (5). Similarly, the lowest PRB index of the 2nd hop PUCCH resource is given by the following equation (6).

[0078] Also, as shown in Figure 12, r PUCCH If the value is between 8 and 15, the lowest PRB index of the 2nd hop PUCCH resource is given by equation (7). Similarly, the lowest PRB index of the 1st hop PUCCH resource is given by equation (8).

[0079] The explanations for equations (5) through (8) are almost the same as those for equations (1) through (4), so please refer to those explanations.

[0080] Finally, with reference to Figure 13, the specific sequence for Option 2 will be described. First, UE200 receives configuration information from gNB100 regarding the PUCCH resource for the Msg4 HARQ-ACK PUCCH for SBFD. Next, based on this configuration information, UE200 assumes that the PRB offset in determining the location of the PUCCH resource is based on the edge of the UL subband. This allows UE200 to transmit the PUCCH within the UL subband.

[0081] As described above, in Operation Example 3, even when SBFD is applied, the location of the PUCCH resource for Msg4 HARQ-ACK PUCCH can be determined by flexibly interpreting the PRB offset. This ensures that Msg4 HARQ-ACK PUCCH can be reliably transmitted within the UL subband, especially when interpretation option 2 is applied, as the PRB offset is determined based on the UL subband. Furthermore, in this operation example, FH can be applied to SBFD slots as well as non-SBFD slots, allowing for more flexible allocation of the PUCCH resource for Msg4 HARQ-ACK PUCCH.

[0082] (4.2.4) Operation Example 4 Operation Example 4 will be explained with reference to Figures 14 to 17. Operation Example 4 allows selection that FH cannot be applied to Msg4 HARQ-ACK PUCCH when SBFD is applied. Operation Example 4 also 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 slot hopping. Figures 14 to 17 show SBFD slots in which the UL subband is set in the middle of the frequency direction. The area outside the UL subband is assumed to be the DL subband.

[0083] Whether or not FH is applicable to Msg4 HARQ-ACK PUCCH within an SBFD symbol may be determined by one of the following: • Alt1: Defined by the specification. That is, FH is always disabled. • Example: The specification disables FH for Msg4 HARQ-ACK PUCCH. • Alt2: Set or indicated by the SIB. • Example: A new parameter in pucch-ConfigCommon (for example, an IE named intra-SlotFH-sbfd-r19) may indicate whether or not FH is disabled for Msg4 HARQ-ACK PUCCH.

[0084] If FH cannot be applied to Msg4 HARQ-ACK PUCCH within an SBFD symbol, the location of the PUCCH resource (start PRB) for Msg4 HARQ-ACK PUCCH may be determined according to one of the following options. The following options are explained using equations (9) to (24), but for explanations of these equations, please refer to the explanations of equations (1) to (4) in Operation Example 3. Note that the following options are explained in terms of how the PRB offset that determines the location of the PUCCH resource is interpreted.

[0085] (Option 1) As shown in Figure 14, the PRB offset is based on the lower edge of the UL BWP. In this case, the location of the PUCCH resource (start PRB) is given by equation (9) or equation (10).

[0086] Additionally, as a variation of Option 1, when determining the location of the PUCCH resource (start PRB), an additional PRB offset (RB) is used. BWP (offset-add) may be applied. In this case, the location of the PUCCH resource (start PRB) is given by the following equation (11) or equation (12). RB in the equation BWP offset-add or RB BWP offset-add・N RB This may be set or indicated by the SIB. Note that this additional PRB offset may have an IE named, for example, additionalPRBOffset-sbfd, to distinguish it from the additional PRB offset applied to RedCap UE.

[0087] (Option 2) As shown in Figure 15, the PRB offset is based on the lower edge of the UL subband (or the UL usable PRBs of the initial BWP). In this case, the location of the PUCCH resource (start PRB) is given by equation (13) or equation (14).

[0088] Furthermore, as a variation of Option 2, when determining the location of the PUCCH resource (start PRB), an additional PRB offset (RB) is used, similar to Option 1. BWP (offset-add) may be applied. In this case, the location of the PUCCH resource (start PRB) is given by the following equation (15) or equation (16). RB in the equation BWP offset-add or RB BWP offset-add・N RB This may be set or indicated by the SIB.

[0089] (Option 3) As shown in Figure 16, the PRB offset is based on the upper edge of the UL BWP. In this case, the location of the PUCCH resource (start PRB) is given by equation (17) or equation (18).

[0090] Furthermore, as a variation of Option 3, when determining the location of the PUCCH resource (start PRB), an additional PRB offset (RB) is used, similar to Option 1. BWP The offset-add may be applied. In this case, the location of the PUCCH resource (start PRB) is given by the following equation (19) or equation (20). RB in the equation BWP offset-add or RB BWP offset-add・N RB This may be set or indicated by the SIB.

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

[0092] Furthermore, as a variation of Option 4, when determining the location of the PUCCH resource (start PRB), an additional PRB offset (RB) is used, similar to Option 1. BWP The offset-add may be applied. In this case, the location of the PUCCH resource (start PRB) is given by the following equation (23) or equation (24). RB in the equation BWP offset-add or RB BWP offset-add・N RB This may be set or indicated by the SIB.

[0093] Furthermore, which option applies may be defined in the specification, or it may be set or indicated by the SIB.

[0094] For the specific sequences of options 2 and 4 in this example, please refer to the example in example 3, as they are almost identical to the specific sequence of option 2.

[0095] As described above, in Operation Example 4, it is possible to select that FH is not applicable to Msg4 HARQ-ACK PUCCH within the SBFD symbol. Furthermore, even when FH is not applicable, the location of the PUCCH resource for Msg4 HARQ-ACK PUCCH can be determined by flexibly interpreting the PRB offset. As a result, especially when interpretations Option 2 and Option 4 are applied, the PRB offset is determined based on the UL subband, so it is possible to reliably transmit Msg4 HARQ-ACK PUCCH within the UL subband. In addition, in this operation example, an additional PRB offset can be applied, so even when the available UL resources are narrow, such as in the SBFD symbol, the PUCCH resource for Msg4 HARQ-ACK PUCCH can be reliably allocated.

[0096] (5) Operation and Effects According to the embodiments described above, even when SBFD is applied to resource allocation, the UE200 can properly set the PUCCH resource for Msg4 HARQ-ACK PUCCH and transmit Msg4 HARQ-ACK PUCCH in the UL subband of the SBFD symbol.

[0098] In the above-described operation example 3, the reference position for the PRB offset may be specified by pucch-ConfigCommon as either the lower or upper end of the BWP, but is not limited to this. The reference position for the PRB offset may be specified by pucch-ConfigCommon as one of four options: the lower or upper end of the BWP, or the lower or upper end of the UL subband. Furthermore, if, for example, the lower or upper end of the UL subband is specified as the reference position for the PRB offset, the UE200 may interpret the PRB offset as described in option 2 of operation example 3.

[0099] In the example operation described above, Msg4 HARQ-ACK PUCCH may be interpreted as Msg4 HARQ-ACK PUCCH repetitions. In other words, repeated transmission may be applied to the example operation described above.

[0118] Each function in the base station 100 and terminal 200 is realized by loading predetermined software (programs) onto hardware such as the processor 1001 and memory 1002, which allows the processor 1001 to perform calculations, control communication by the communication device 1004, and control at least one of the reading and writing of data in the memory 1002 and storage 1003.

[0130] The specific operations described in this disclosure as being performed by a base station may, in some cases, be performed by its upper node. In a network consisting of one or more network nodes having a base station, it is clear that various operations performed for communication with a terminal can be performed by the base station and at least one other network node (for example, an MME or S-GW, but not limited to these). Although the above example illustrates the case where there is one other network node besides the base station, it may also be a combination of multiple other network nodes (for example, an MME and an S-GW).

[0131] Information and signals (such as data) can be output from a higher layer (or lower layer) to a lower layer (or higher layer). Input and output may occur via multiple network nodes.

[0132] Input and output information may be stored in a specific location (e.g., memory) or managed using a management table. Input and output information may be overwritten, updated, or appended to. Output information may be deleted. Input information may be transmitted to other devices.

[0133] The determination may be made by a value represented by one bit (0 or 1), by a boolean value (true or false), or by a numerical comparison (for example, a comparison with a predetermined value).

[0134] Each aspect / embodiment described in this disclosure may be used individually, in combination, or switched between as needed during implementation.

[0140] Furthermore, the information, parameters, etc., described in this disclosure may be expressed using absolute values, relative values ​​from a given value, or other corresponding information. For example, wireless resources may be indicated by an index.

[0141] The names used for the parameters described above are not restrictive in any way. Furthermore, the formulas and other expressions using these parameters may differ from those expressly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by any suitable name, and therefore, the various names assigned to these various channels and information elements are not restrictive in any way.

Base stations may also be referred to by terms such as macrocell, small cell, femtocell, and picocell.

[0143] A base station can house one or more (e.g., three) cells (also called sectors). If a base station houses multiple cells, the entire coverage area of ​​the base station can be divided into multiple smaller areas, each of which may be provided with communication services by a base station subsystem (e.g., a Remote Radio Head, RRH). The terms "cell" or "sector" refer to part or all of the coverage area of ​​at least one of the base station and / or base station subsystems providing communication services in that coverage.

[0144] In this disclosure, the transmission of information by a base station to a terminal may be interpreted as the base station instructing the terminal to perform control or operation based on the information.

This also includes the case when the mobile body is stationary. The mobile body includes, but is not limited to, vehicles, transport vehicles, automobiles, motorcycles, bicycles, connected cars, excavators, bulldozers, wheel loaders, dump trucks, forklifts, trains, buses, handcarts, rickshaws, ships and other watercraft, airplanes, rockets, satellites, drones (registered trademark), multicopters, quadcopters, balloons, and items mounted on them. The mobile body may also be a mobile body that moves autonomously based on operation commands. It may be a vehicle (e.g., a car, an airplane, etc.), an unmanned mobile body (e.g., a drone, an autonomous vehicle, etc.), or a robot (manned or unmanned). Furthermore, at least one of the base station and the mobile station may include devices that do not necessarily move during communication operations. For example, at least one of the base station and the mobile station may be an Internet of Things (IoT) device such as a sensor.

[0148] Furthermore, the term "base station" in this disclosure may be interpreted as "terminal." For example, the various aspects / embodiments of this 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), Vehicle-to-Everything (V2X), etc.). In this case, the terminal 200 may have the functions that the base station 100 has. Also, terms such as "uplink" and "downlink" may be interpreted as terms corresponding to terminal-to-terminal communication (for example, "side"). For example, uplink channel, downlink channel, etc., may be interpreted as side channel.

[0149] Similarly, the term "terminal" in this disclosure may be replaced with "base station." In this case, the base station 100 may be configured to have the same functions as the terminal 200 described above.

[0150] Figure 19 shows an example of the configuration of vehicle 2001. As shown in Figure 19, 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.

[0151] The drive unit 2002 is composed of, for example, an engine, a motor, or a hybrid of an engine and a motor.

[0152] The steering unit 2003 includes at least a steering wheel (also called a handle) and is configured to steer at least one of the front wheels and the rear wheels based on the operation of the steering wheel, which is operated by the user.

[0153] The electronic control unit 2010 consists of a microprocessor 2031, memory (ROM, RAM) 2032, and communication ports (IO ports) 2033. Signals from various sensors 2021 to 2027 installed in the vehicle are input to the electronic control unit 2010. The electronic control unit 2010 may also be called an Electronic Control Unit (ECU).

[0154] Signals from various sensors 2021 to 2029 include current signals from the current sensor 2021 that senses motor current, front and rear wheel rotation speed signals obtained by the rotation speed sensor 2022, front and rear wheel air pressure signals obtained by the air pressure sensor 2023, vehicle speed signals obtained by the vehicle speed sensor 2024, acceleration signals obtained by the acceleration sensor 2025, accelerator pedal depression signals obtained by the accelerator pedal sensor 2029, brake pedal depression signals obtained by the brake pedal sensor 2026, shift lever operation signals obtained by the shift lever sensor 2027, and detection signals obtained by the object detection sensor 2028 for detecting obstacles, vehicles, pedestrians, etc.

[0155] The Information Services Unit 2012 consists of various devices for providing (outputting) various types of information such as driving information, traffic information, and entertainment information, including car navigation systems, audio systems, speakers, televisions, and radios, and one or more ECUs that control these devices. The Information Services Unit 2012 uses information acquired from external devices via communication modules 2013, etc., to provide various multimedia information and multimedia services to the occupants of the vehicle 2001.

[0156] The Information Services Unit 2012 may include input devices that accept input from external sources (e.g., keyboards, mice, microphones, switches, buttons, sensors, touch panels, etc.) and output devices that output to external sources (e.g., displays, speakers, LED lamps, touch panels, etc.).

[0157] The driver assistance system unit 2030 consists of various devices that provide functions to prevent accidents or reduce the driver's workload, such as millimeter-wave radar, Light Detection and Ranging (LiDAR), cameras, positioning locators (e.g., GNSS), map information (e.g., high-definition (HD) maps, autonomous vehicle (AV) maps), gyro systems (e.g., Inertial Measurement Unit (IMU), Inertial Navigation System (INS)), Artificial Intelligence (AI) chips, and AI processors, as well as one or more ECUs that control these devices. The driver assistance system unit 2030 also sends and receives various information via the communication module 2013 to realize driver assistance functions or autonomous driving functions.

[0158] The communication module 2013 can communicate with the microprocessor 2031 and components of the vehicle 2001 via its communication port. For example, the communication module 2013 sends and receives data via the communication port 2033 between the drive unit 2002, steering unit 2003, accelerator pedal 2004, brake pedal 2005, shift lever 2006, left and right front wheels 2007, left and right rear wheels 2008, axle 2009, the microprocessor 2031 and memory (ROM, RAM) 2032 in the electronic control unit 2010, and sensors 2021 to 2029 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 external devices. For example, it can send and receive various types of information to and from external devices 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 or a mobile station.

[0160] The communication module 2013 may transmit at least one of the following to an external device via wireless communication: signals from the various sensors 2021 to 2029 input to the electronic control unit 2010, information obtained based on said signals, and information based on input from an external source (user) obtained via the information service unit 2012. The electronic control unit 2010, the various sensors 2021 to 2029, the information service unit 2012, etc., may also be called input units that accept input. For example, the PUSCH transmitted by the communication module 2013 may include information based on the above input.

[0161] The communication module 2013 receives various information (traffic information, signal information, vehicle-to-vehicle information, etc.) transmitted from external devices and displays it on the information service unit 2012 installed in the vehicle. The information service unit 2012 may also be called an output unit, which outputs information (for example, it outputs information to devices such as displays and speakers based on the PDSCH (or data / information decoded from the PDSCH) received by the communication module 2013).

[0162] Furthermore, the communication module 2013 stores various information received from external devices in memory 2032, which is available to the microprocessor 2031. Based on the information stored in memory 2032, the microprocessor 2031 may control the drive unit 2002, steering unit 2003, accelerator pedal 2004, brake pedal 2005, shift lever 2006, left and right front wheels 2007, left and right rear wheels 2008, axles 2009, sensors 2021 to 2029, etc., which are provided in the vehicle 2001.

[0163] As used in this disclosure, the terms “determining” and “determining” may encompass a wide variety of actions. “Determining” may include, for example, judging, calculating, computing, processing, deriving, investigating, looking up, searching, or inquiring (e.g., searching in a table, database, or other data structure), or ascertaining. “Determining” may also include receiving (e.g., receiving information), transmitting (e.g., sending information), inputting, outputting, or accessing (e.g., accessing data in memory). Furthermore, “determining” may include resolving, selecting, choosing, establishing, or comparing. In other words, "judgment" and "decision" can include considering that some action has been "judged" or "decided." Also, "judgment (decision)" can be reinterpreted as "assuming," "expecting," or "considering."

[0164] The terms “connected,” “coupled,” and any variations thereof mean 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” with each other. The coupling or connection between elements may be physical, logical, or a combination thereof. For example, “connection” may be reinterpreted as “access.” As used in this disclosure, two elements may be considered to be “connected” or “coupled” with each other using at least one of one or more wires, cables, and printed electrical connections, and, in some non-limiting and non-exclusive examples, electromagnetic energy having wavelengths in the radio frequency domain, microwave domain, and optical (both visible and invisible) domain.

[0165] The reference signal may also be abbreviated as RS, and may be called Pilot depending on the applicable standard.

[0166] In this disclosure, the phrase "based on" does not mean "based solely on" unless otherwise specified. In other words, the phrase "based on" means both "based solely on" and "based at least on."

[0167] Any reference to elements using the designations “first,” “second,” etc., as used in this disclosure does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient way to distinguish between two or more elements. Accordingly, references to the first and second elements do not imply that only two elements may be employed, or that the first element must precede the second element in any way.

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

[0169] Where the terms “include,” “including,” and variations thereof are used in this disclosure, these terms are intended to be inclusive, as is the term “comprising.” Furthermore, the term “or” as used in this disclosure is not intended to mean exclusive OR.

[0170] A wireless frame may consist of one or more frames in the time domain. Each of these frames in the time domain may be called a subframe. A subframe may further consist 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 communication parameters applied to at least one of the transmission and reception of a signal or channel. Numerology may include, for example, at least one of the following: subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame configuration, specific filtering processes performed by the transceiver in the frequency domain, and specific windowing processes performed by the transceiver in the time domain.

[0172] A slot may consist of one or more symbols in the time domain (such as Orthogonal Frequency Division Multiplexing (OFDM) symbols or Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols). A slot may also be a time unit based on neurology.

[0173] A slot may include multiple mini-slots. Each mini-slot may consist of one or more symbols in the time domain. Mini-slots may also be called sub-slots. Mini-slots may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a mini-slot may be called a PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot may be called a PDSCH (or PUSCH) mapping type B.

[0174] Wireless frames, subframes, slots, minislots, and symbols all represent units of time when transmitting a signal. Different names may be used for each of these terms.

[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. In other words, at least one of a subframe and a TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (e.g., 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 unit of time for scheduling in wireless communication. For example, in an LTE system, the base station schedules each terminal to allocate radio resources (such as the frequency bandwidth and transmission power available to each terminal) in TTI units. However, the definition of TTI is not limited to this.

[0177] TTI may be a transmission time unit for channel-encoded data packets (transport blocks), code blocks, code words, etc., or it may be a processing unit for scheduling, link adaptation, etc. Note that when a TTI is given, the actual time interval (e.g., number of symbols) in which the transport block, code block, code word, etc. are mapped may be shorter than the given TTI.

[0178] Furthermore, if one slot or one mini-slot is referred to as TTI, then one or more TTIs (i.e., one or more slots or one or more mini-slots) may constitute the minimum time unit of scheduling. In addition, the number of slots (number of mini-slots) that constitute the minimum time unit of scheduling may be controlled.

[0179] A TTI with a time length of 1 ms may also be called a normal TTI (TTI in LTE Rel. 8-12), a long TTI, a normal subframe, a long subframe, or a slot. A TTI shorter than a normal TTI may also be called a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a mini slot, a subslot, or a slot.

[0180] Furthermore, long TTIs (e.g., normal TTIs, subframes, etc.) may be interpreted as TTIs with a time length exceeding 1 ms, and short TTIs (e.g., shortened TTIs, etc.) may be interpreted as TTIs with a TTI length less than that of a long TTI but 1 ms or more.

[0181] A resource block (RB) is a resource allocation unit in the time domain and frequency domain, and in the frequency domain, it may contain one or more consecutive subcarriers. The number of subcarriers in an RB may be the same regardless of the neurology, for example, 12. The number of subcarriers in an RB may be determined based on the neurology.

[0182] Furthermore, the time domain of RB may contain one or more symbols and may be the length of one slot, one minislot, one subframe, or one TTI. One TTI, one subframe, etc., may each consist of one or more resource blocks.

[0183] One or more RBs may also be called Physical RBs (PRBs), Sub-Carrier Groups (SCGs), Resource Element Groups (REGs), PRB pairs, RB pairs, etc.

[0184] Furthermore, a resource block may consist of one or more resource elements (REs). For example, one RE may be a radio resource area of ​​one subcarrier and one symbol. A bandwidth part (BWP) (also called a partial bandwidth, etc.) may represent a subset of consecutive common resource blocks (RBs) for a given neurology in a given carrier. Here, the common RBs may be identified by an index of the RBs relative to the common reference point of the carrier. PRBs may be defined in a BWP and numbered within that BWP.

[0185] A BWP may include BWPs for UL (UL BWP) and BWPs for DL ​​(DL BWP). One or more BWPs may be configured within a single carrier for a UE.

[0186] At least one of the configured BWPs may be active, and the UE does not need to assume that it will send or receive a given signal / channel outside of the active BWP. In this disclosure, terms such as "cell" and "carrier" may be read as "BWP".

[0187] The structures described above, such as wireless frames, subframes, slots, minislots, and symbols, are merely illustrative. For example, the number of subframes included in a wireless frame, the number of slots per subframe or wireless 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, and the number of symbols, symbol length, and cyclic prefix (CP) length within a TTI can be varied in various ways.

[0188] The term "maximum transmit power" as used in this disclosure may mean the maximum transmit power, the nominal UE maximum transmit power, or the rated UE maximum transmit power.

[0189] In this disclosure, if articles are added through translation, such as a, an, and the in English, this disclosure may include the fact that the noun following these articles is plural.

[0190] In this 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 "combine" may be interpreted similarly to "different."

[0191] Although the present disclosure has been described in detail above, it will be 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 intent and scope of the present disclosure as defined by the claims. Therefore, the descriptions in the present disclosure are illustrative and not intended to be restrictive in any way.
