Description

Terminal and communication method

[0001] The present disclosure relates to a terminal and a communication method.

[0002] 3GPP (registered trademark) has established specifications for the 5th generation mobile communication system (5G, also known as New Radio (NR) or Next Generation (NG)), and is also working on specifications for next-generation mobile communication systems called 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 a time division duplexing (TDD) band. This duplexing scheme is called subband non-overlapping full duplex (SBFD). 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] Additionally, for Release 19, extensions are being considered for UL transmission and DL reception across SBFD and non-SBFD symbols in different slots.

[0006] In current wireless communication systems, channels or signals can be configured to be transmitted or received repeatedly (eg, CG PUSCH, SPS PDSCH, PDSCH repetition, etc.).

[0007] The behavior of such periodic / semi-persistent channels or signals or repetitive (transmission) when SBFD is applied is not specified. Without such clarification, the channels or signals may not be transmitted or received properly, which may result in degraded system performance.

[0009] A terminal according to one aspect of the present disclosure includes a receiving unit that receives first information regarding a periodic or semi-persistent signal or channel and second information regarding a first time unit in which a plurality of subbands constituting a time division duplex band can be used, and a control unit that determines, based on the first information and the second information, resources including the first time unit and / or the second time unit to which the time division duplex is applied, for receiving or transmitting the signal or the channel.

[0011] 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.

[0012] 1 is a wireless communication system conforming to a method called 5G. Alternatively, the wireless communication system 10 may be a wireless communication system conforming to a method called Beyond 5G, 5G Evolution, or 6G.

[0013] 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 enables simultaneous communication with two base stations.

[0014] As shown in FIG. 1 , the 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."

[0015] The gNB100 may be a base station in a Centralized-Radio Access Network (C-RAN) configuration having a distributed unit (DU) having a function for connecting to the UE200 and a central unit (CU) having a function for connecting to the network. In this case, the gNB100 may be read as a DU, a CU, or a DU and a CU. When the gNB100 is read as a DU, it may be called a gNB-DU. When the gNB100 is read as a CU, it may be called a gNB-CU. When the gNB100 is read as a DU and a CU, the DU portion may be called a gNB-DU and the CU portion may be called a gNB-CU.

[0016] The wireless communication system 10 may also support multiple frequency ranges (FR). That is, as shown in Fig. 2, the wireless communication system 10 may support the following FRs: FR1: 410 MHz to 7.125 GHz FR2-1: 24.25 GHz to 52.6 GHz FR2-2: Over 52.6 GHz to 71 GHz

[0017] In FR1, a subcarrier spacing (SCS) of 15, 30, or 60 kHz and a bandwidth (BW) of 5 to 100 MHz may be used, while in FR2-1, an SCS of 60 or 120 kHz (or even 240 kHz) and a BW of 50 to 400 MHz may be used.

[0018] Note that SCS may be interpreted as numerology, which is defined in 3GPP TS 38.300 and corresponds to one subcarrier spacing in the frequency domain.

[0019] 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.

[0020] 3 is a diagram showing an example of the configuration of a radio frame (system frame), subframe, and slot used in the radio communication system 10. As shown in FIG. 3, one slot is composed of 14 symbols, and the larger (wider) the SCS, the shorter the symbol period (and slot period). However, the SCS is not limited to the interval (frequency) shown in FIG. 3. For example, 480 kHz, 960 kHz, etc. may be used as the SCS.

[0021] Furthermore, the number of symbols constituting one slot does not necessarily have to be 14 (for example, it may be 28 or 56 symbols, etc.) Furthermore, the number of slots per subframe may differ depending on the SCS.

[0022] 3 may be called a time domain, a symbol period, a symbol time, etc. The frequency direction may be called a frequency domain, a resource block, a subcarrier, a bandwidth part (BWP), etc.

[0023] The wireless communication system 10 may support coverage enhancement (CE) that expands the coverage of a cell (or a physical channel) formed by the gNB 100. In coverage enhancement, a mechanism for increasing the success rate of reception of various physical channels, such as repeated transmission (repetition) of a PRACH (physical random access channel), may be provided.

[0024] For example, UE200 receives information related to the random access procedure from gNB100 as a downlink (DL) signal (e.g., SIB1 (System Information Block Type 1) etc.).

[0025] Further, for example, UE 200 transmits PRACH as an UL signal to gNB 100 using a RACH occasion, i.e., a RACH (transmission) opportunity (RO: RACH Occasion), which is a resource for transmitting a random access preamble. For example, UE 200 repeatedly transmits PRACH as an UL signal to gNB 100.

[0026] The UL signal may include, for example, a UL data signal and control information. For example, the UL signal may include information related to the processing capability of the UE 200 (e.g., UE capability). The UL signal may also include a reference signal.

[0027] Channels used for transmitting UL signals include, for example, data channels and control channels. For example, the data channel may include a physical uplink shared channel (PUSCH), and the control channel may include a physical uplink control channel (PUCCH). For example, the UE 200 transmits control information using the PUCCH and transmits UL data signals using the PUSCH. Note that the PUSCH is an example of an uplink shared channel, and the PUCCH is an example of an uplink control channel. The shared channel may also be called a data channel.

[0028] The reference signal included in the UL signal may include, for example, at least one of a Demodulation Reference Signal (DMRS), a Phase Tracking Reference Signal (PTRS), a Channel State Information - Reference Signal (CSI-RS), a Sounding Reference Signal (SRS), and a Positioning Reference Signal (PRS) for position information. For example, reference signals such as the DMRS and PTRS are used to demodulate the UL data signal and are transmitted using the PUSCH.

[0029] Meanwhile, in response to the operation of UE200, gNB100 transmits information related to the RACH procedure to UE200 as a DL signal (e.g., SIB1, etc.).

[0030] Also, for example, gNB100 receives PRACH as an UL signal from UE200. For example, gNB100 repeatedly receives PRACH from UE200 as an UL signal.

[0031] Channels used for transmitting DL signals include, for example, data channels and control channels. For example, the data channel may include a physical downlink shared channel (PDSCH), and the control channel may include a physical downlink control channel (PDCCH). For example, the gNB 100 transmits control information to the UE 200 using the PDCCH, and transmits DL data signals using the PDSCH. Note that the PDSCH is an example of a downlink shared channel, and the PDCCH is an example of a downlink control channel. Note that the PDCCH may be interpreted as downlink control information (DCI), control information, etc. transmitted in the PDCCH.

[0032] The reference signal included in the DL signal may include, for example, at least one of a DMRS, a PTRS, a CSI-RS, an SRSRS, and a PRS for location information. For example, the reference signal such as the DMRS or the PTRS is used for demodulating the DL data signal and is transmitted using the PDSCH.

[0033] Next, SBFD and CG (Configured Grant) PUSCH / SPS (Semi-Persistent Scheduling) PDSCH will be described.

[0034] <SBFD Operation> Considering the time ratio of transmission and reception (e.g., DL:UL = 4:1) using Time Division Duplex (TDD) up to Rel. 16, there may be cases where the number of transmission opportunities for UL signals / channels is fewer than the number of reception opportunities for DL ​​signals / channels. In such cases, UE 200 cannot frequently transmit UL signals / channels, and there is a concern that transmission delays of important UL signals / channels may occur. In addition, since there are fewer UL transmission opportunities compared to DL reception opportunities, there is also a concern that signal / channel congestion may occur during UL transmission opportunities. Furthermore, in TDD, the time resources available for transmitting UL signals / channels are limited, which limits the application of UL coverage extension techniques, for example, through repetition transmission.

[0035] In future wireless communication systems (for example, Rel. 18 and later), the introduction of a time-frequency division duplexing method that combines TDD and frequency division duplexing (FDD) for UL and DL is being considered.

[0036] Examples of the time-frequency division duplexing method include XDD (Cross Division Duplex) or Subband Non-Overlapping Full Duplex (SBFD). XDD or SBFD may refer to a duplexing method in which DL and UL are frequency-division multiplexed within one component carrier (CC) of the TDD band (DL and UL can be used simultaneously).

[0037] Fig. 4A is a diagram showing an example of TDD configuration defined up to Rel. 16. In the example shown in Fig. 4A, TDD slots or symbols are configured for a UE in a bandwidth such as one component carrier (CC) (which may also be called a cell or a serving cell) or bandwidth portion (BWP).

[0038] In the example shown in Fig. 4A, the time ratio of DL slots to UL slots is 4: 1. In such a conventional TDD slot or symbol setting, UL time resources cannot be sufficiently secured, which may result in UL transmission delays and degradation of coverage performance.

[0039] 4B is a diagram showing an example of the configuration of SBFD. In the example shown in FIG. 4B, within one component carrier (CC), resources used for DL ​​reception and resources used for UL transmission overlap in time. With this resource configuration, more UL resources can be secured, thereby improving resource utilization efficiency.

[0040] For example, as shown in the example of Fig. 4B, both ends of the frequency domain may be set as DL resources, and these DL resources may sandwich UL resources. This may prevent or mitigate cross link interference (CLI) with neighboring carriers. Furthermore, a guard region may be set at the boundary between the DL resource and the UL resource.

[0041] Considering the complexity of processing self-interference, it may be considered that only the base station 100 uses the DL resource and the UL resource simultaneously. That is, in radio resources where the DL and UL overlap in time, one UE 200 may use the DL resource and another UE 200 may use the UL resource.

[0042] Fig. 5 is a diagram showing an example of SBFD operation. In the example shown in Fig. 5, part of the DL resources of the TDD band is configured as UL resources, and the DL and UL are configured to partially overlap in the time domain.

[0043] In the example shown in FIG. 5, during the DL-only period, each of the multiple UEs 200 (UE1 and UE2 in FIG. 5) receives the DL channel / signal.

[0044] In addition, during a period in which the DL and UL channels overlap in time, one UE 200 (UE1 in the example of FIG. 5) receives a DL channel / signal, and another UE 200 (UE2 in the example of FIG. 5) transmits a UL channel / signal. During this period, the base station 100 performs simultaneous transmission and reception of the DL and UL channels.

[0045] Furthermore, during the UL-only period, each of the multiple UEs 200 (UE1 and UE2 in FIG. 5) transmits a UL channel / signal.

[0046] In the existing NR (for example, as defined by Rel. 15 / 16 / 17), the DL frequency resource and the UL frequency resource in the UE carrier are configured as the DL BWP and the UL BWP, respectively. In order to switch the DL / UL frequency resource to another DL / UL frequency resource, multiple BWP configurations and a BWP adaptation mechanism are required.

[0047] 6A is a diagram showing an example of an existing TDD configuration. In FIG. 6A, slots / symbols marked with "D" are DL slots / symbols, slots / symbols marked with "U" are UL slots / symbols, and slots / symbols marked with "F" are flexible (hereinafter also referred to as FL) slots / symbols. Note that similar notations may be used in the following figures.

[0048] In the existing NR, as shown in FIG. 6A, the time resources (time units such as symbols, slots, etc.) in the TDD carrier for UE 200 are configured as at least one of DL, UL, and flexible (FL) in the TDD configuration.

[0049] 6B is a diagram showing an example of an existing TDD configuration. In FIG. 6B, slots / symbols or subbands marked with "D" are DL slots / symbols or DL ​​subbands, and slots / symbols or subbands marked with "U" are UL slots / symbols or UL subbands. Note that similar notations may be used in the following figures.

[0050] As shown in FIG. 6B , the SBFD symbol may be a symbol that is signaled or configured as UL (or DL) or for UL transmission (or DL ​​reception) on some frequency resources (subbands), and signaled or configured as DL (or UL) or for DL ​​reception (or UL transmission) on other frequency resources (subbands). Alternatively, the SBFD symbol may be a symbol that is signaled or configured as UL (or DL) or for UL transmission (or DL ​​reception) on a portion of the frequency resources. Alternatively, the SBFD symbol may be a symbol that is signaled or configured as DL (or UL) or for DL ​​reception (or UL transmission) on a portion of the frequency resources.

[0051] Here, the time unit may be at the symbol level, slot / subslot level, or a group of symbols / slots / subslots, i.e., an SBFD time unit may be an SBFD symbol, a slot / subslot containing or overlapping an SBFD symbol, or a group of symbols / slots / subslots containing or overlapping an SBFD symbol.

[0052] A pure time unit may be a non-SBFD symbol (i.e., a symbol that is not an SBFD symbol, also referred to as a non-SBFD symbol), a slot / subslot that does not include or overlap an SBFD symbol, or a group of symbols / slots / subslots that do not include or overlap an SBFD symbol, and may also be referred to as a non-SBFD time unit. For example, a pure time unit may be referred to as a time unit consisting only of DL on a frequency resource as shown in FIG. 7A, or as a time unit consisting only of UL on a frequency resource as shown in FIG. 7B.

[0053] Furthermore, for an SBFD time unit, DL resources and UL resources may have various allocation patterns in the frequency domain. For example, an SBFD time unit of frequency domain pattern #1 may have an allocation pattern as shown in FIG. 7C . An SBFD time unit of frequency domain pattern #2 may have an allocation pattern as shown in FIG. 7D . An SBFD time unit of frequency domain pattern #3 may have an allocation pattern as shown in FIG. 7E . These allocation patterns are merely exemplary, and other allocation patterns may be used. The frequency domain pattern of an SBFD time unit may refer to a resource repetition pattern in the frequency domain for the SBFD time unit.

[0054] As described above, SBFD may be applied to each slot / symbol. Note that each slot / symbol may be set to DL, UL, or Flexible (FL) that can be used as DL or UL, and then SBFD may be applied.

[0055] 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 described as a duplexing scheme in which multiple sub-bands are specified within the TDD band, a duplexing scheme in which UL and DL are allocated non-overlapping in the frequency direction within the TDD time unit, or full-duplex duplexing of sub-bands.

[0056] A symbol to which SBFD is applied is also called an SBFD symbol. "SBFD is applied" may be interpreted as SBFD being applied to at least a part of 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. Also, "a time unit 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.

[0057] Furthermore, a UE that supports SBFD operation is referred to as an SBFD-aware UE or an SBFD-capable UE, and a UE that does not support SBFD operation is referred to as a legacy UE. For example, when SBFD is applied to a DL symbol, an SBFD-aware UE can recognize the UL subband (and DL subband) in this SBFD symbol, but a legacy UE recognizes this SBFD symbol as a normal DL symbol.

[0058] The following explains the terms related to SBFD. SBFD DL symbol: A symbol indicated as DL by the tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, and for which an SBFD subband is configured SBFD FL symbol: A symbol indicated as FL by the tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, and for which an SBFD subband is configured SBFD SSB symbol: A symbol configured for SSB reception, and for which an SBFD subband is configured non-SBFD symbol: A symbol for which an SBFD subband is not configured, and / or a symbol for which SBFD operation is not performed on the gNB side

[0059] <CG PUSCH> There are Type 1 CG PUSCH and Type 2 CG PUSCH. Type 1 CG PUSCH is only RRC configured (i.e., does not rely on DCI), and transmission parameters are provided by configuredGrantConfig, pusch-Config, and rrc-ConfiguredUplinkGrant. On the other hand, Type 2 CG PUSCH is RRC configured and DCI activation / deactivation is performed, and one DCI can activate only one CG PUSCH configuration, and one DCI can deactivate multiple CG PUSCH configurations, and transmission parameters are provided by configuredGrantConfig, pusch-Config, and activation DCI. (See FIG. 8.) configuredGrantConfig, pusch-Config, and activation DCI may be referred to as information about periodic or semi-persistent signals or channels, etc.

[0060] <SPS PDSCH> Rel. 16 supports multiple SPS configurations. SPS can be activated / deactivated by DCI. Transmission parameters for SPS PDSCH are provided by sps-Config and Activation DCI (see Figure 9). The sps-Config and Activation DCI may also be referred to as periodic or semi-persistent signal or channel-related information.

[0061] <Analysis> For UL transmission and DL reception across SBFD and non-SBFD symbols in different slots (each transmission / reception in a slot includes either all SBFD symbols or all non-SBFD symbols), the following options will be considered for SBFD-aware UEs: Option 1: Transmission / reception is limited to only SBFD symbols or only non-SBFD symbols; Option 2: Transmission / reception can occur in SBFD and non-SBFD symbols. Note that in the 3GPP RAN1#116 meeting, it was agreed to refer to the UL subband frequency resources in an active UL BWP as UL usable PRBs and the DL subband frequency resources in an active DL BWP as DL usable PRBs (see Figure 10).

[0062] Regarding the above-mentioned periodic / semi-persistent channels / signals (e.g., SPS PDSCH, CG PUSCH, SR PUCCH, P (Periodic) / SP (Semi-Persistent or Semi-Periodic) CSI PUCCH, P / SP SRS, P / SP CSI-RS) or PDSCH / PUSCH / PUCCH repetition, it is not clarified whether and how to receive or transmit the channel / signal occasions taking into account different symbol types.

[0063] More specifically, for example, the following points are not clarified (see Figures 11A and 11B): Whether one configuration of periodic / semi-persistent channel / signal occasions or PDSCH / PUSCH / PUCCH repetitions is allowed in different symbol types; If one configuration of periodic / semi-persistent channel / signal occasions or PDSCH / PUSCH / PUCCH repetitions (transmissions) is possible in SBFD symbols and non-SBFD symbols, is an extension necessary to take into account different available DL / UL resources in SBFD symbols?

[0064] If this point is not clarified, periodic / semi-persistent channels / signals or PDSCH / PUSCH / PUCCH repetitions may not be properly received or transmitted, which may result in degradation of system performance.

[0065] Therefore, in the following, the present proposal will be described by focusing on the SPS PDSCH, CG PUSCH, SR PUCCH, P / SP CSI PUCCH, P / SP SRS occasion, and PDSCH repetition as examples.

[0066] The outline of this proposal is as follows:

[0067] Proposal 1 includes the following Proposal 1-1 and Proposal 1-2 regarding SPS PDSCH: Proposal 1-1: Support SPS PDSCH reception occasions / PDSCH repetitions of one SPS setting in SBFD symbols or non-SBFD symbols for occasions within different periods. Proposal 1-2: Restrict SPS PDSCH reception occasions / PDSCH repetitions of one SPS setting to only in SBFD symbols or non-SBFD symbols.

[0068] Proposal 2 includes the following Proposal 2-1 and Proposal 2-2 regarding CG PUSCH and / or SP CSI reporting on PUSCH and / or P / SP CSI reporting on PUCCH and / or SR PUCCH and / or P / SP SRS. Proposal 2-1: Support CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS transmission occasions with one CG / SP CSI report / SR report / SRS configuration in SBFD symbols or non-SBFD symbols for occasions within different CG / SP CSI report / SRS periods. Proposal 2-2: Support CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP with one CG / SP CSI report / SR report / SRS configuration. SRS transmission occasions are restricted to only SBFD symbols or only non-SBFD symbols.

[0069] The items described in the following Proposal 1 and Proposal 2 may be combined as appropriate as long as no contradiction occurs.

[0070] In the following, SBFD symbols and non-SBFD symbols may be read as SBFD slots and non-SBFD slots, respectively.

[0071] As described above, the configuredGrantConfig, pusch-Config, and Activation DCI described with respect to the CG PUSCH, and the sps-Config and Activation DCI described with respect to the SPS PDSCH, which are transmitted from the base station to the terminal, may be referred to as information about a periodic or semi-persistent signal or channel, etc. Configuration information about PDSCH repetition, etc., transmitted from the base station to the terminal may also be referred to as information about a periodic or semi-persistent signal or channel, etc. Hereinafter, the terminal may receive, from the base station, information about a periodic or semi-persistent signal or channel, and information about a time unit (SBFD symbol, SBFD slot, etc.) in which multiple subbands constituting a time division duplex band can be used.

[0072] <Proposal 1> As mentioned above, proposal 1 relates to SPS PDSCH.

[0073] <Proposal 1-1> Proposal 1-1 supports SPS PDSCH occasions of one SPS configuration and / or PDSCH repetition occurring within an SBFD symbol or within non-SBFD symbols of SPS PDSCH occasions and / or PDSCH repetitions of different periods. Hereinafter, "and / or" may be written as / .

[0074] For SPS PDSCH occasions / PDSCH repetitions in SBFD symbols and FDRA for occasions in non-SBFD symbols, Options 1-A and 1-B below are provided.

[0075] <Proposal 1-1: Option 1-A> A single FDRA is applied to SPS PDSCH occasions / PDSCH repetitions in SBFD symbols and occasions in non-SBFD symbols.

[0076] For Option 1-A, Options 1-A-1 to 1-A-3 are provided. <Proposal 1-1: Option 1-A: 1-A-1> When there is an SPS PDSCH occasion / PDSCH repetition within an SBFD symbol, the PDSCH frequency resource is not expected to overlap with RBs outside the DL subband (or DL ​​usable PRBs) (the terminal does not expect overlap). Expected may be used interchangeably with assumed.

[0077] <Proposal 1-1: Option 1-A: 1-A-2> If an SPS PDSCH occasion / PDSCH repetition overlaps with an RB outside the DL subband (or a PRB available for DL), the terminal does not receive the SPS PDSCH occasion / PDSCH repetition.

[0078] <Proposal 1-1: Option 1-A: 1-A-2'> If an SPS PDSCH occasion overlaps with an RB outside the DL subband (or a PRB available for DL), the terminal postpones the SPS PDSCH occasion / PDSCH repetition to the first slot in which the SPS PDSCH occasion / PDSCH repetition does not overlap with an SBFD symbol.

[0079] <Proposal 1-1: Option 1-A: 1-A-3> If an SPS PDSCH occasion / PDSCH repetition overlaps with RBs outside the DL subband (or DL ​​usable PRBs), the terminal receives the SPS PDSCH occasion only in RBs within the DL subband (or DL ​​usable PRBs). For example, as shown in Option 1-A-3 of FIG. 12, the terminal receives the SPS PDSCH occasion only in RBs within the DL subband (or DL ​​usable PRBs).

[0080] <Proposal 1-1: Option 1-A: 1-A-3: Variation 1> If there are no RBs in the DL subband (or DL ​​usable PRBs) for the SPS PDSCH occasion / PDSCH repetition in the SBFD symbol, the terminal does not receive the SPS PDSCH occasion / PDSCH repetition in the SBFD symbol.

[0081] <Proposal 1-1: Option 1-A: 1-A-3: Variation 2> The TB (Transport Block) size of the SPS PDSCH occasion is determined based only on the RBs in the DL subband (or the PRBs available in DL), or is determined based on the RBs indicated by the FDRA.

[0082] Whether it is based on the indicated FDRA or the RBs indicated in the FDRA in the DL / UL subband (or the PRBs available in DL) may be defined by the specification, configured by higher layer signaling such as RRC, or determined based on the RBs used for the first SPS PDSCH after activation.

[0083] <Proposal 1-1: Option 1-A: 1-A-3: Variation 3> The TB size for PDSCH repetition is determined based on the indicated FDRA for PDSCH repetition or based on the RBs in the DL subband (or PRBs available in DL) for PDSCH repetition within the SBFD symbol.

[0084] Whether it is based on the indicated FDRA or on the RBs indicated in the FDRA in the DL subband (or on the PRBs available in DL) may be defined by the specification, configured by RRC, or determined based on the RBs used for the first PDSCH repetition.

[0085] <Proposal 1-1: Option 1-A: Variation> The terminal may decide whether to apply Option 1-A-1 / 1-A-2 / 1-A-2' / 1-A-3 based on RRC settings, specification definition, or predefined rules.

[0086] Example of RRC configuration: Explicit RRC parameters are configured to enable one of the above options. If the parameter is not configured, the remaining options apply. For example, explicit RRC parameters are configured to enable options 1-A-2' / 1-A-3. If the parameter is not applied, options 1-A-1 / 1-A-2' apply.

[0087] Example rule: If the number of RBs in the DL subband (or DL ​​usable PRBs) for SPS PDSCH occasions / PDSCH repetitions within an SBFD symbol is greater / less than a threshold, then option 1-A-3 applies. Otherwise, option 1-A-2 / 1-A-2' applies. The threshold may be set by RRC or defined by a specification.

[0088] Example rule: If the ratio between the number of RBs in the DL subband (or DL ​​usable PRBs) for SPS PDSCH occasions / PDSCH repetitions within an SBFD symbol and the number of RBs allocated by the indicated / configured FDRA is greater / less than a threshold, Option 1-A-3 is applied. Otherwise, Option 1-A-2 / 1-A-2' is applied. The threshold may be set by the RRC or defined by a specification.

[0089] <Proposal 1-1: Option 1-B> Separate FDRA is applied to SPS PDSCH occasions / PDSCH repetitions in SBFD symbols and SPS PDSCH occasions / PDSCH repetitions in non-SBFD symbols.

[0090] For Option 1-B, Options 1-B-1 and 1-B-2 are provided. <Proposal 1-1: Option 1-B: 1-B-1> Separate FDRA fields are indicated by DCI for SPS PDSCH occasions / PDSCH repetitions in SBFD symbols and non-SBFD symbols, respectively.

[0091] <Proposal 1-1: Option 1-B: 1-B-2> The FDRA indicated by DCI is applied to SPS PDSCH occasions / PDSCH repetitions in non-SBFD symbols. The FDRA for SBFD symbols is determined separately.

[0092] For option 1-B-2, options 1-B-2-1 to 1-B-2-3 are provided.

[0093] <Proposal 1-1: Option 1-B: 1-B-2: 1-B-2-1> The FDRA for the SPS PDSCH occasion / PDSCH repetition in the SBFD symbol is determined based on the indicated FDRA and RB offset. For example, as shown in Option 1-B-2-1 of Figure 12, the FDRA for the SPS PDSCH occasion / PDSCH repetition in the SBFD symbol is determined based on the indicated FDRA and RB offset.

[0094] For example, the starting RB in an SBFD symbol is given by (starting RB in non-SBFD symbols + RB offset) mod DL BWP size

[0095] The RB offset may be indicated by the DCI or configured by the RRC. For example, the RB offset may be configured for each SPS configuration or for a common configuration of all SPS configurations.

[0096] <Proposal 1-1: Option 1-B: 1-B-2: 1-B-2-2> The FDRA for the SPS PDSCH occasion / PDSCH repetition is determined by shifting RBs outside the DL subband (or the PRBs available in DL) to RBs within the DL subband (or the PRBs available in DL). For example, the FDRA is determined as shown in Option 1-B-2-2 of FIG. 12.

[0097] The total number of RBs for SPS PDSCH occasions / PDSCH repetitions in an SBFD symbol is the same as the number of RBs for SPS PDSCH occasions / PDSCH repetitions in a non-SBFD symbol.

[0098] <Proposal 1-1: Option 1-B: 1-B-2: 1-B-2-3> The FDRA for SPS PDSCH occasions / PDSCH repetitions within an SBFD symbol is determined based on re-interpreting the FDRA field.

[0099] For example, in the case of FDRA indicated by activation DCI, the frequency domain resources within the SBFD symbol are determined by interpreting the FDRA bits using the DL subband size / location (instead of the DL BWP size / location).

[0100] Note that in legacy, the FDRA field bits for PDSCH are interpreted based on the DL BWP size / location.

[0101] <Proposal 1-1: Option 1-B: Variation 1> The TB size of the SPS PDSCH occasion is determined based only on the RBs in the DL subband (or the PRBs available in DL), or based on the RBs indicated by the FDRA.

[0102] Whether this is based on the indicated FDRA or on the FDRA indicated RB in the DL / UL subband (or the PRBs available in DL / UL) is defined by the specification, configured by the RRC, or determined based on the RBs used for the first SPS PDSCH after activation.

[0103] The TB size of the PDSCH repetition is determined based on the FDRA indicated for the PDSCH repetition or based on the RBs in the DL subband (or DL ​​usable PRBs) for the PDSCH repetition within the SBFD symbol.

[0104] Whether it is based on the indicated FDRA or on the FDRA indicated RBs in the DL subband (or the DL available PRBs) is defined by the specification, configured by RRC, or determined based on the RBs used for the first PDSCH repetition.

[0105] <Proposal 1-1: Option 1-B: Variation 2> Option 1-B is applied only when the indicated FDRA overlaps with an RB outside the DL subband (or the PRBs available for DL).

[0106] If the FDRA does not overlap with RBs outside the DL subband (or DL ​​usable PRBs) in the SBFD symbol, the same FDRA applies to SPS PDSCH occasions / PDSCH repetitions in the SBFD symbol and to SPS PDSCH occasions / PDSCH repetitions in non-SBFD symbols.

[0107] If the FDRA overlaps with RBs outside the DL subband (or DL ​​usable PRBs) within the SBFD symbol, option 1-B applies.

[0108] <Proposal 1-1: Option 1-B: Variation 2> For the FDRA in the SBFD symbol determined based on Option 1-B-2-1 / 1-B-2-2 / 1-B-2-3 above, the terminal expects that the FDRA determined in the SBFD symbol does not overlap with RBs outside the DL subband (or DL ​​usable PRBs).

[0109] For the FDRA in the SBFD symbol determined based on the above Option 1-B-2-1 / 1-B-2-2 / 1-B-2-3, if the FDRA determined in the SBFD symbol overlaps with an RB outside the DL subband (or the PRB usable in DL), the terminal does not receive the SPS PDSCH occasion / PDSCH repetition in the SBFD symbol.

[0110] <Proposal 1-1: Variation> Different options can be applied to different frequency domain RA types. For example, for PDSCH RA type 0, option 1-A-3 can be applied. For PDSCH RA type 1, option 1-B can be applied.

[0111] Which option to apply is configured by the RRC (eg, configured per SPS configuration) or is determined based on specific rules.

[0112] <Proposal 1-2> In Proposal 1-2, SPS PDSCH occasions of one SPS setting / PDSCH repetition are limited to only SBFD symbols or only non-SBFD symbols.

[0113] <Proposal 1-2: Example 1> The terminal does not expect that an SPS PDSCH occasion of one SPS setting / PDSCH repetition is in an SBFD symbol or a non-SBFD symbol for the occasion.

[0114] <Proposal 1-2: Example 2> - Due to SPS configuration or PDSCH repetition, the terminal receives SPS PDSCH occasions only in SBFD / non-SBFD symbols.

[0115] The SBFD / non-SBFD symbol type for the SPS occasion / PDSCH repetition is determined based on the RRC configuration / scheduling DCI / activation DCI / first SPS PDSCH / first PDSCH repetition / FDRA.

[0116] RRC parameters configured for the SPS PDSCH configuration

[0117] Scheduling / Activation DCI The field for SBFD / non-SBFD type indication in the scheduling / activation DCI indicates the symbol type.

[0118] The DCI format is configured as SBFD / non-SBFD type. If the DCI format of the scheduling / activation DCI is configured as SBFD / non-SBFD, the terminal receives SPS occasions / PDSCH repetitions only in SBFD / non-SBFD symbols.

[0119] The scheduling / activation DCI indicates the SBFD / non-SBFD symbol type of the PDCCH symbol that activates the SPS configuration or schedules the PDSCH repetition. For example, if the scheduling / activation DCI is in a non-SBFD symbol, the terminal receives SPS occasions / PDSCH repetitions only in non-SBFD symbols. If the scheduling / activation DCI PDCCH is in an SBFD symbol, the terminal receives SPS occasions / PDSCH repetitions only in SBFD symbols.

[0120] Symbol type of the first SPS PDSCH or first PDSCH repetition after an activation DCI If the first SPS PDSCH after an activation DCI is in a non-SBFD symbol, the terminal receives the SPS PDSCH occasion only in non-SBFD symbols. If the first SPS PDSCH after an activation DCI is in a SBFD symbol, the terminal receives the SPS PDSCH occasion only in SBFD symbols.

[0121] If the first PDSCH repetition is within a non-SBFD symbol, the terminal receives the PDSCH repetition only in the non-SBFD symbol. If the first PDSCH repetition is within a SBFD symbol, the terminal receives the PDSCH repetition only in the SBFD symbol.

[0122] FDRA indicated for SPS configuration or PDSCH repetition If the FDRA is within the DL subband (or a DL usable PRB), the terminal receives the SPS occasion / PDSCH repetition only in SBFD symbols. If the FDRA overlaps with any RB outside the DL subband (or a DL usable PRB), the terminal receives the SPS occasion / PDSCH repetition only in non-SBFD symbols.

[0123] The terminal does not receive SPS occasions / PDSCH repetitions in other symbol types.

[0124] If the terminal determines to receive SPS occasions / PDSCH repetitions only in non-SBFD symbols, the terminal does not receive SPS occasions / PDSCH repetitions that overlap with SBFD symbols.

[0125] If the terminal determines to receive SPS occasions / PDSCH repetitions only in SBFD symbols, the terminal does not receive SPS occasions / PDSCH repetitions that overlap with non-SBFD symbols.

[0126] <Proposal 2> As mentioned above, Proposal 2 relates to CG PUSCH and / or SP CSI reporting on PUSCH and / or P / SP CSI reporting on PUCCH and / or SR PUCCH and / or P / SP SRS.

[0127] <Proposal 2-1> Proposal 2-1 proposes a case where transmission opportunities for CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS of one CG / SP CSI report / SR report / SRS configuration are supported within an SBFD symbol or a non-SBFD symbol for opportunities in different CG / SP CSI report / SR SRS periods.

[0128] The FDRA for transmission opportunities of CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS in SBFD symbols and non-SBFD symbols may follow one of the following options:

[0129] (Option 2-A) A single FDRA may be applied to CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities in SBFD symbols and non-SBFD symbols.

[0130] (Option 2-A-1) In the case of CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS in an SBFD symbol, the UE does not assume that frequency resources overlap with RBs outside the UL subband (or PRBs usable in the UL).

[0131] For a CG / SP CSI report / SR report / SRS configuration, if some CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities are within the SBFD symbol, the UE may assume the indicated / configured frequency resource for the CG / SP CSI report / SR report / SRS configuration is within the UL subband (or UL usable PRB).

[0132] (Option 2-A-2) If the CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH opportunities overlap with RBs outside the UL subband (or UL usable PRBs), the UE does not transmit the CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH opportunities.

[0133] Alternatively, if the P / SP SRS opportunity overlaps with an RB outside the UL subband (or UL usable PRBs), the UE does not transmit SRS in the SBFD symbol.

[0134] (Option 2-A-3) If the CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH opportunities overlap with RBs outside the UL subband (or UL usable PRBs), the UE transmits the CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH opportunities only on RBs within the UL subband (or UL usable PRBs) (see FIG. 13 ).

[0135] Alternatively, if the P / SP SRS opportunities overlap with RBs outside the UL subband (or UL usable PRBs), the UE transmits P / SP SRS only on RBs within the UL subband (or UL usable PRBs) within the SBFD symbol.

[0136] (Option 2-A-3 Variation 1) If there is no RB within the UL subband (or UL usable PRB) of a CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunity within an SBFD symbol, the UE transmits the CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunity in the SBFD symbol.

[0137] (Variation 2 of Option 2-A-3) The UE does not consider the case where there are no RBs in the UL subband (or UL usable PRBs) for the CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities within the SBFD symbol.

[0138] (Variation 3 of Option 2-A-3) The TB size of the CG PUSCH opportunity may be determined based only on the RBs within the UL subband (or the PRBs available in the UL), may be indicated by the FDRA, or may be determined based on the RBs.

[0139] (Variations of Option 2-A) Option 2-A-2 and Option 2-A-3 may be supported in the specification, or the UE may decide which option to apply based on an RRC configuration (such as a configuration for each CG configuration) or a rule.

[0140] (Example of RRC configuration) To enable Option 2-A-3, explicit RRC parameters (such as for each CG / SP CSI report / SR report / SRS configuration or for all CG / SP CSI reports / SR reports / SRS configurations in common) may be configured. Note that if no RRC parameters are configured, Option 2-A-1 or Option 2-A-2 may be applied.

[0141] (Example Rule 1) Option 2-A-3 may be applied if the number of RBs in the UL subband (or UL usable PRBs) is greater than / less than a threshold. The threshold may be configured by RRC or defined by a specification. The UE transmits CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities only on RBs in the UL subband (or UL usable PRBs).

[0142] Otherwise, Option 2-A-2 may be applied, i.e., the UE does not transmit CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities in the SBFD symbol.

[0143] (Example Rule 2) Option 2-A-3 may be applied if the ratio of the "number of RBs in the DL subband (or DL ​​usable PRBs)" to the "number of RBs allocated by the indicated FDRA" is greater than / less than a threshold. The threshold may be set by the RRC or defined by a specification. The UE transmits CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities only on RBs in the UL subband (or UL usable PRBs).

[0144] Otherwise, Option 2-A-2 applies, i.e., the UE does not transmit CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities in the SBFD symbol.

[0145] (Option 2-B) Separate FDRA may be applied to CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities in SBFD symbols and opportunities in non-SBFD symbols.

[0146] (Option 2-B-1) A separate FDRA field may be indicated by the CG / SP CSI PUSCH report activation DCI, may be configured in the Type 1 CG / P SRS / SP SRS configuration, and may be configured in the PUCCH resource for the SR / CSI PUCCH report for each of the SBFD symbol case and the non-SBFD symbol case.

[0147] (Option 2-B-2) In each of the cases of SBFD symbols and non-SBFD symbols, separate PUCCH resources may be configured in the SP CSI / SR PUCCH reporting configuration.

[0148] (Option 2-B-3) The indicated / configured FDRA may be applied to CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities in non-SBFD symbols. The FDRA for SBFD symbols may be determined separately.

[0149] (Option 2-B-3-1) The FDRA of the CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities within the SBFD symbol may be determined based on the indicated / configured FDRA and RB offset.

[0150] For example, the starting RB of the SBFD symbol may be (starting RB of the non-SBFD symbol + RB offset) modulo the UL BWP size, or (starting RB of the non-SBFD symbol + RB offset) modulo the UL subband size (or the PRB size available in the UL) (see Figure 13).

[0151] The RB offset may be indicated by the activation DCI or may be configured by the RRC (e.g., configured per CG / SP CSI report / SR report / SRS, or configured commonly for all CG / SP CSI reports / SR reports / SRS configurations).

[0152] (Option 2-B-3-2) The FDRA of the CG PUSCH / SP CSI PUSCH opportunity within the SBFD symbol may be determined based on reinterpretation of the FDRA field.

[0153] For example, in the case of FDRA indicated by the activation DCI (or configured for Type 1 CG configuration), the frequency domain resources within the SBFD symbol may be determined by interpreting the FDRA bits using the UL subband size / position (instead of the UL BWP size / position) (see Figure 13).

[0154] (Variations of Option 2-B) (Variation 1) Option 2-B may be applied only when the indicated / configured FDRA overlaps with RBs outside the UL subband (or UL usable PRBs).

[0155] If the indicated / configured FDRA does not overlap with RBs outside the UL subband (or UL usable PRBs) within an SBFD symbol, the same FDRA is applied to CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities within the SBFD symbol and to opportunities in non-SBFD symbols. Option 2-B does not apply.

[0156] If the indicated / configured FDRA overlaps with RBs outside the UL subband (or UL usable PRBs) within the SBFD symbol, Option 2-B applies.

[0157] (Variation 2) The FDRA within the SBFD symbol is determined based on Option 2-B-1 / 2-B-2 / 2-B-3.

[0158] (Variation 3) The UE assumes that the FDRA determined in the SBFD symbol does not overlap with RBs outside the UL subband (or UL usable PRBs).

[0159] (Variation 4) If the FDRA determined in the SBFD symbol overlaps with an RB outside the UL subband (or the UL usable PRBs), the UE does not transmit the CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS in the SBFD symbol.

[0160] (Variations of Proposal 2-1 (including Option 2-A and Option 2-B)) Different options may be applied to different frequency domain RA types. Option 2-A-3 applies to PUSCH RA Type 0, and Option 2-B applies to PUSCH RA Type 1.

[0161] Different options may be applied to Type 1 CG and Type 2 CG. Different options may be applied to CG PUSCH, SP CSI PUSCH, SP CSI PUCCH, SR PUCCH, P SRS, and SP SRS.

[0162] Which option is applied may be configured by the RRC (such as configured for each CG configuration), may be determined based on specific rules, or may be defined by specifications.

[0163] <Proposal 2-2> Proposal 2-2 describes a case where opportunities for CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS for one CG / SP CSI report / SR report / SRS configuration are limited to only SBFD symbols or only non-SBFD symbols.

[0164] (Example 1) The UE does not assume that there is one CG / SP CSI report / SR report / SRS configured CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunity within an SBFD symbol or a non-SBFD symbol for the opportunity.

[0165] (Example 2) In the case of CG / SP CSI report / SR report / SRS configuration, the UE transmits CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities only in SBFD symbols / only in non-SBFD symbols.

[0166] The SBFD / non-SBFD symbol type for a CG opportunity (i.e., whether the UE transmits the CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunity on an SBFD symbol or a non-SBFD symbol) may be determined based on (1) RRC configuration, (2) activation DCI, (3) the first CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunity, or (4) indicated / configured FDRA.

[0167] (1) Regarding RRC Settings: In this case, the RRC parameters are set for CG / SP CSI report / SR report / SRS settings indicating SBFD / non-SBFD type.

[0168] (2) Regarding Activation DCI For example, the SBFD / non-SBFD type indication field in the Activation DCI indicates the symbol type.

[0169] For example, the DCI format may configure the SBFD / non-SBFD type. If the DCI format of the activation DCI is configured as SBFD / non-SBFD, the UE transmits CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities only in SBFD / non-SBFD symbols.

[0170] For example, the SBFD / non-SBFD symbol type may be configured depending on the PDCCH symbol that activates the CG configuration. If the activation DCI PDCCH is within a non-SBFD symbol, the UE transmits CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities only in non-SBFD symbols. If the activation DCI PDCCH is within a SBFD symbol, the UE transmits CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities only in SBFD symbols.

[0171] (3) Symbol type of first CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunity (after DCI activation)

[0172] For example, if the first CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunity (after the Activation DCI) is in a non-SBFD symbol, the UE will transmit the CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunity only in the non-SBFD symbols. If the first CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunity (after DCI activation) is within the SBFD symbol, the UE shall transmit the CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunity in the SBFD symbol only.

[0173] (4) Regarding FDRA indicated for CG configuration: For example, if the indicated / configured FDRA is within the UL subband (or UL usable PRB), the UE transmits CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities only in SBFD symbols. If the FDRA overlaps with any RB outside the UL subband (or UL usable PRB), the UE transmits CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities only in non-SBFD symbols.

[0174] The UE does not transmit CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities in other symbol types.

[0175] If the UE decides to transmit CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities only on non-SBFD symbols, the UE does not transmit CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities that overlap with SBFD symbols.

[0176] If the UE decides to transmit CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities only in SBFD symbols, the UE shall not transmit CG PUSCH / SP CSI PUSCH / P CSI PUCCH / SP CSI PUCCH / SR PUCCH / P SRS / SP SRS opportunities that overlap with non-SBFD symbols.

[0177] <UE capability> UE capability indicating the capabilities of a terminal may include the following information indicating the capabilities of the terminal. For example, new UE capabilities and report signaling (and RRC settings) shown below may be defined for each UE / FR / FC, etc. Terminal 200 may report the following information indicating the capabilities of the terminal to base station 100. Note that the information indicating the capabilities of the terminal may correspond to information defining the capabilities of the terminal. - Whether the UE supports transmission of CG PUSCH occasions with one CG setting in SBFD symbols and non-SBFD symbols - Whether the UE supports reception of SPS PDSCH occasions with one SPS setting in SBFD symbols and non-SBFD symbols

[0178] Next, the configurations of the base station 100 and the terminal 200 will be described. Note that the configurations of the base station 100 and the terminal 200 described below are examples of functions related to this embodiment. The base station 100 and the terminal 200 may have functions not shown. Furthermore, the functional divisions and / or names of the functional units are not limited as long as the functions perform the operations related to this embodiment.

[0179] <Configuration of Base Station> Fig. 14 is a block diagram showing an example of the configuration of base station 100 according to this embodiment. Base station 100 includes, for example, a transmitting unit 101, a receiving unit 102, and a control unit 103. Base station 100 communicates with terminal 200 (see Fig. 15) wirelessly.

[0180] The transmitter 101 transmits a downlink (DL) signal to the terminal 200. For example, under the control of the controller 103, the transmitter 101 transmits a DL signal (for example, the above-mentioned RRC, SIB, MAC CE, DCI, notification, confirmation, etc.).

[0181] The DL signal may include, for example, a downlink data signal and control information (e.g., Downlink Control Information (DCI)). The DL signal may also include information indicating scheduling related to signal transmission of terminal 200 (e.g., an UL grant). The DL signal may also include control information of higher layers (e.g., control information of Radio Resource Control (RRC)). The DL signal may also include a reference signal.

[0182] The channels used for transmitting DL signals include, for example, a downlink data channel and a downlink control channel. For example, the downlink data channel may include a PDSCH (Physical Downlink Shared Channel), and the downlink control channel may include a PDCCH (Physical Downlink Control Channel). For example, the base station 100 transmits downlink control information to the terminal 200 using the PDCCH and transmits downlink data signals using the PDSCH.

[0183] The reference signal included in the DL signal may include at least one of a demodulation reference signal (Demodulation Reference Signal (DMRS)), a Phase Tracking Reference Signal (PTRS), a Channel State Information-Reference Signal (CSI-RS), a Sounding Reference Signal (SRS), and a Positioning Reference Signal (PRS) for position information. For example, reference signals such as DMRS and PTRS are used for demodulating downlink data signals and are transmitted using the PDSCH.

[0184] The receiving unit 102 receives an uplink (UL) signal transmitted from the terminal 200. For example, the receiving unit 102 receives an UL signal (for example, the above-mentioned request, notification, etc.) under the control of the control unit 103.

[0185] The transmitting unit 101 and the receiving unit 102 may be collectively referred to as a communication unit.

[0186] The control unit 103 controls the communication operations of the base station 100 , including the transmission processing of the transmission unit 101 and the reception processing of the reception unit 102 .

[0187] For example, the control unit 103 acquires information such as data and control information from the upper layer and outputs it to the transmitting unit 101. The control unit 103 also outputs the data, control information, etc. received from the receiving unit 102 to the upper layer.

[0188] For example, the control unit 103 allocates resources (or channels) used for transmitting and receiving DL signals and / or resources used for transmitting and receiving UL signals based on signals (e.g., data and control information, etc.) received from the terminal 200 and / or data and control information, etc. acquired from a higher layer. Information on the allocated resources may be included in control information transmitted to the terminal 200.

[0189] 15 is a block diagram showing an example of the configuration of terminal 200 according to this embodiment. Terminal 200 includes, for example, receiving unit 201, transmitting unit 202, and control unit 203. Terminal 200 communicates with base station 100, for example, wirelessly.

[0190] The transmitter 202 transmits an UL signal to the base station 100. For example, the transmitter 202 transmits the UL signal under the control of the controller 203. For example, the transmitter 202 may transmit an MsgA PRACH in a valid MsgA RO determined by the controller 203, or may transmit an MsgA PUSCH in a valid MsgA PO determined by the controller 203.

[0191] The UL signal may include, for example, an uplink data signal and control information (e.g., UCI). For example, information related to the processing capability of the terminal 200 (e.g., UE capability) may be included. The UL signal may also include a reference signal.

[0192] Channels used for transmitting UL signals include, for example, an uplink data channel and an uplink control channel. For example, the uplink data channel includes a PUSCH (Physical Uplink Shared Channel), and the uplink control channel includes a PUCCH (Physical Uplink Control Channel). For example, terminal 200 transmits uplink control information to base station 100 using the PUCCH and transmits uplink data signals using the PUSCH.

[0193] The reference signals included in the UL signal may include, for example, at least one of DMRS, PTRS, CSI-RS, SRS, and PRS. For example, the reference signals such as DMRS and PTRS are used for demodulating the uplink data signal and are transmitted using an uplink channel (for example, PUSCH).

[0194] The receiving unit 201 and the transmitting unit 202 may be collectively referred to as a communication unit.

[0195] The control unit 203 controls the communication operations of the terminal 200 , including the reception processing in the receiving unit 201 and the transmission processing in the transmitting unit 202 .

[0196] For example, the control unit 203 acquires information such as data and control information from the upper layer and outputs it to the transmitting unit 202. Also, the control unit 203 outputs, for example, the data and control information received from the receiving unit 201 to the upper layer.

[0197] For example, the control unit 203 controls transmission of information to be fed back to the base station 100. The information to be fed back to the base station 100 may include, for example, HARQ-ACK, Channel State Information (CSI), or a Scheduling Request (SR). The information to be fed back to the base station 100 may be included in UCI.

[0198] For example, the receiving unit 201 may receive first information regarding a periodic or semi-persistent signal or channel and second information regarding a first time unit in which multiple subbands constituting a time division duplex band are available, and the control unit 203 may determine, based on the first information and the second information, resources including the first time unit and / or the second time unit to which time division duplex is applied, for receiving or transmitting the signal or channel. The first information may be common to the first time unit and the second time unit, and the control unit 203 may determine, based on the first information and the second information, resources including the first time unit and the second time unit. The first information may include first information for the first time unit and first information for the second time unit, and the control unit 203 may determine resources including the first time unit and the second time unit, based on the first information for the first time unit, the first information for the second time unit, and the second information. The control unit 203 may not assume that a signal or channel will be received or transmitted in both the first time unit and the second time unit.

[0199] Note that the channel used for transmitting the DL signal and the channel used for transmitting the UL signal are not limited to the above-mentioned example. For example, the channel used for transmitting the DL signal and the channel used for transmitting the UL signal may include a Random Access Channel (RACH) and a Physical Broadcast Channel (PBCH). The RACH may be used to transmit Downlink Control Information (DCI) including a Random Access Radio Network Temporary Identifier (RA-RNTI), for example.

[0200] With the above configuration, it is possible to appropriately receive or transmit channels or signals when a plurality of sub-bands constituting a time division duplex band are available.

[0201] Summary of Embodiment As described above, according to one aspect of the present disclosure, there is provided a terminal including: a receiving unit that receives first information related to a periodic or semi-persistent signal or channel and second information related to a first time unit in which a plurality of subbands constituting a time division duplex band are available; and a control unit that determines, based on the first information and the second information, resources including the first time unit and / or the second time unit to which the time division duplex is applied, for receiving or transmitting the signal or the channel.

[0202] With the above configuration, resources for receiving or transmitting a signal or channel can be determined based on the first information and the second information, so that a channel or signal can be appropriately received or transmitted when multiple subbands constituting a time division duplex band are available.

[0203] In one example, the first information is common to the first time unit and the second time unit, and the control unit determines the resource including the first time unit and the second time unit based on the first information and the second information.

[0204] With the above configuration, a channel or a signal can be properly received or transmitted by simply using a single piece of first information that is common to the first time unit and the second time unit.

[0205] In one example, the first information includes first information for the first time unit and first information for the second time unit, and the control unit determines the resource including the first time unit and the second time unit based on the first information for the first time unit, the first information for the second time unit, and the second information.

[0206] With the above configuration, by using different first information for the first time unit and the second time unit, the first time unit and the second time unit are notified separately and individually.

[0207] In one example, the control unit does not expect to receive or transmit the signal or the channel in both the first time unit and the second time unit.

[0208] The above configuration enables simple control of receiving or transmitting a signal or channel in only one of the first time unit and the second time unit.

[0209] According to one aspect of the present disclosure, there is provided a communication method in which a terminal receives first information regarding a periodic or semi-persistent signal or channel and second information regarding a first time unit in which a plurality of subbands constituting a time division duplex band are available, and determines, based on the first information and the second information, resources including the first time unit and / or the second time unit to which the time division duplex is applied, for receiving or transmitting the signal or the channel.

[0210] With the above configuration, resources for receiving or transmitting a signal or channel can be determined based on the first information and the second information, so that a channel or signal can be appropriately received or transmitted when multiple subbands constituting a time division duplex band are available.

[0233] 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.

[0242] A base station can accommodate one or more (e.g., three) cells. When a base station accommodates multiple cells, the overall coverage area of ​​the base station can be partitioned into multiple smaller areas, and each smaller area can also 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 the entire coverage area of ​​a base station and / or base station subsystem that provides communication services within that coverage area.

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 IoT (Internet of Things) device such as a sensor.

[0247] Furthermore, a base station in the present disclosure may be read as a terminal. For example, the 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, D2D (Device-to-Device) or V2X (Vehicle-to-Everything)). In this case, the terminal may be configured to have the functions of the base station 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.

[0248] Similarly, the term "terminal" in the present disclosure may be read as "base station." In this case, the base station may be configured to have the functions of the terminal described above.

[0260] <Meaning and Interpretation of Terms> 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 a table, database, or other data structure), ascertaining something that is considered to be a "judging" or "determining," and the like. "Determining" and "determining" may also include receiving (e.g., receiving information), transmitting (e.g., sending information), input, output, accessing (e.g., accessing data in memory), and the like that are considered to be a "judging" or "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.

[0261] 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.

[0262] <Reference Signal> A reference signal can also be abbreviated as RS (Reference Signal), and may also be called a pilot depending on the applicable standard.

[0263] <Meaning of "based on"> 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."

[0264] "First," "Second" Any reference to an element using designations such as "first," "second," etc., 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 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 precede the second element in some way.

[0265] <Means> The "means" in the configuration of each device above may be replaced with "section," "circuit," "device," etc.

[0266] Open Format: When the terms "include," "including," and variations thereof are used in this disclosure, these terms are intended to be inclusive, similar to the term "comprising." Furthermore, when the term "or" is used in this disclosure, it is not intended to be an exclusive or.

[0267] <Time Units such as TTI, Frequency Units such as RB, and Radio Frame Configuration> 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.

[0268] Numerology may be a communication parameter that applies to the transmission and / or reception of a signal or channel, and may indicate, for example, at least one of subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame structure, specific filtering operations performed by the transceiver in the frequency domain, and specific windowing operations performed by the transceiver in the time domain.

[0269] A slot may be composed 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.

[0270] 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.

[0271] 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.

[0272] For example, one subframe may be called a transmission time interval (TTI), multiple consecutive subframes may be called a TTI, or one slot or one minislot may be called a TTI. That is, at least one of the subframe and the TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (for example, 1-13 symbols), or a period longer than 1 ms. Note that the unit representing the TTI may be called a slot, minislot, etc. instead of a subframe.

[0273] Here, TTI refers to, for example, the smallest time unit for scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling to allocate radio resources (such as frequency bandwidth and transmission power that can be used by each user terminal) to each user terminal in TTI units. Note that the definition of TTI is not limited to this.

[0274] 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.

[0275] 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.

[0276] A TTI having a time length of 1 ms may be called a regular TTI (TTI in LTE Rel. 8-12), normal TTI, long TTI, regular subframe, normal subframe, long subframe, slot, etc. A TTI shorter than a regular TTI may be called a shortened TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, minislot, subslot, slot, etc.

[0277] 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 greater than or equal to 1 ms.

[0278] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and may include one or more consecutive subcarriers in the frequency domain. The number of subcarriers included in an RB may be the same regardless of numerology, for example, 12. The number of subcarriers included in an RB may be determined based on numerology.

[0279] 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.

[0280] 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, etc.

[0281] 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.

[0282] 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 BWP and numbered within the BWP.

[0283] 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.

[0284] 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."

[0285] The above-described structures of radio frames, subframes, slots, minislots, symbols, etc. are merely examples, and various changes may be made to 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.

[0286] <Maximum Transmit Power> The "maximum transmit power" in the present disclosure may refer to the maximum value of transmit power, the nominal UE maximum transmit power, or the rated UE maximum transmit power.

[0287] Articles 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.

[0288] <"Different"> In the present disclosure, the term "A and B are different" may mean "A and B are different from each other." Note that 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."
