Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is based on and claims the benefit of priority from Japanese Patent Application No. 2023-23442, filed on February 17, 2023, the entire contents of which are incorporated herein by reference. [Technical Field]

[0002] The present disclosure relates to a terminal device, a terminal device method, and a base station device. [Background technology]

[0003] In recent years, technological development related to extended reality (XR) has progressed. XR is a concept that includes multimedia integration technologies such as virtual reality (VR), augmented reality (AR), mixed reality (MR), and substitutional reality (SR). In XR, 3D time-series image data in real and / or virtual spaces, audio data in multiple channels (stereo, 5.1ch, etc.), other data presented to the user, control data, etc. are transmitted and received in parallel. XR requires low latency and high reliability to maintain and improve the quality of the user experience.

[0004] Non-Patent Document 1 discusses the implementation of XR in 5G NR (Fifth Generation New Radio), a wireless specification defined by the Third Generation Partnership Project (3GPP (registered trademark)). [Prior art documents] [Non-patent literature]

[0005] [Non-Patent Document 1] 3GPP TR 38.838 V17.0.0 (2021-12) [Non-patent document 2] 3GPP TS 38.214 V17.0.0 (2021-12) Summary of the Invention

[0006] XR is expected to be operated under various requirements, including low latency. For XR traffic, the use of configured grant (CG) scheduling, rather than dynamic grant (DG) scheduling, for uplink transmission from terminal devices is being considered. Conventionally, one transmission occasion is set in a single CG period. However, this configuration may not satisfy the requirements of XR.

[0007] In consideration of the above, CG that sets multiple transmission opportunities in one period has been studied. Furthermore, a process in which a terminal device transmits information regarding unused occasions among multiple transmission opportunities to a base station device has also been studied. The inventors have found that such a configuration requires a procedure for the terminal device and / or base station device to appropriately determine the size (i.e., the number of bits or bit width) of the above information. However, Non-Patent Document 2 does not describe such a procedure. The above problem also arises in ordinary terminal devices and base station devices that are not implemented with XR.

[0008] The present disclosure provides a technique that can appropriately determine the size of information related to unused opportunities among multiple transmission opportunities.

[0009] A terminal device according to the present disclosure includes: a receiver that receives a Radio Resource Control (RRC) message including a configured grant (CG) configuration from a base station device, the CG configuration including information for configuring multiple Physical Uplink Shared Channel (PUSCH) transmission opportunities based on the configured uplink grant, and information for configuring a number of bits of Uplink Control Information (UCI) including information on unused transmission occasions; a controller that determines a number of bits of a bitmap of the UCI based on the information for configuring the number of bits of the UCI; and a transmitter that executes each of the multiple PUSCH transmissions based on the information for configuring the multiple PUSCH transmission opportunities. The controller multiplexes the bitmap of the UCI having the determined number of bits onto each of the multiple PUSCH transmissions.

[0010] Furthermore, a method for a terminal device in the present disclosure includes receiving, from a base station device, a Radio Resource Control (RRC) message including a configured grant (CG) configuration, where the CG configuration includes information for configuring multiple Physical Uplink Shared Channel (PUSCH) transmission opportunities based on the configured uplink grant and information for configuring a number of bits of Uplink Control Information (UCI) including information on unused transmission occasions, determining a number of bits of a bitmap of the UCI based on the information for configuring the number of bits of the UCI, and performing each of the multiple PUSCH transmissions based on the information for configuring the multiple PUSCH transmission opportunities. The method further includes multiplexing the bitmap of the UCI having the determined number of bits onto each of the multiple PUSCH transmissions.

[0011] Furthermore, the base station apparatus in the present disclosure includes: a transmitter that transmits a Radio Resource Control (RRC) message including a configured grant (CG) configuration to a terminal apparatus, the CG configuration including information for configuring multiple Physical Uplink Shared Channel (PUSCH) transmission opportunities based on the configured uplink grant, and information for configuring a number of Uplink Control Information (UCI) bits including information on unused transmission occasions; and a receiver that receives the multiple PUSCH transmissions. A bitmap of the UCI having a number of bits determined based on the information for configuring the number of UCI bits is multiplexed onto each of the multiple PUSCH transmissions.

[0012] According to the above configuration, it is possible to appropriately determine the size of information related to unused opportunities among a plurality of transmission opportunities. Note that the above configuration may achieve other effects instead of or in addition to the above effect. [Brief explanation of the drawings]

Not all of the combinations of elements included in each of the following embodiments are necessarily essential for realizing the present disclosure, and some of the elements can be omitted as appropriate. Therefore, the scope of the present disclosure is not limited to the configurations described in each of the following embodiments.

The communication system S1 is configured in accordance with predetermined technical specifications (Technical Specifications, TS). For example, the communication system S1 may comply with technical specifications (e.g., 5G, 5G Advanced, 6G, etc.) defined by 3GPP.

[0017] In the communication system S1, a user plane (User Plane) through which user data is transmitted and received and a control plane (Control Plane) through which control data is transmitted and received are configured separately. That is, the communication system S1 supports C / U separation. The user plane is abbreviated as U-plane, and the control plane is abbreviated as C-plane.

[0018] The terminal device 10 is a device that performs wireless communication with the base station device 20 and may be, for example, user equipment (UE) that operates in accordance with the 3GPP 5G NR specification.

[0020] The base station device 20 manages at least one cell. A cell constitutes the smallest unit of a communication area. For example, one cell belongs to one frequency (e.g., carrier frequency) and is composed of one component carrier. The term "cell" can refer to wireless communication resources and can also refer to a communication target of the terminal device 10. The base station device 20 wirelessly communicates with the terminal device 10 located in its own cell in the U-plane and C-plane. In other words, the base station device 20 terminates the U-plane protocol and C-plane protocol for the terminal device 10.

[0021] The base station device 20 communicates with the core network 30 in the U-plane and the C-plane. More specifically, the core network 30 includes multiple logical nodes including an Access and Mobility Management Function (AMF) and a User Plane Function (UPF). The base station device 20 connects to the AMF in the C-plane and connects to the UPF in the U-plane.

[0022] The base station device 20 may be, for example, a gNB that provides a U-plane and a C-plane conforming to the 3GPP 5G NR specification to the terminal device 10 and connects to the 3GPP 5GC (5G Core Network). Alternatively, the base station device 20 may be a device conforming to another older or newer 3GPP specification.

[0023] The base station device 20 may be configured with a plurality of unit devices. For example, the base station device 20 may be configured with a central unit (CU), a distributed unit (DU), and a radio unit (RU).

[0024] A radio access network (RAN) is formed by interconnecting multiple base station devices 20. The radio access network formed by the base station devices 20 that are gNBs may be referred to as an NG-RAN. The base station devices 20 that are gNBs may be referred to as NG-RAN nodes.

[0025] The plurality of base station devices 20 are connected to each other via a predetermined interface (for example, an Xn interface). More specifically, for example, the plurality of base station devices 20 are connected to each other via an Xn-U interface in the U-plane, and are connected to each other via an Xn-C interface in the C-plane. Note that the plurality of base station devices 20 may also be connected to each other via other interfaces with different functions or names.

[0026] Each base station device 20 is connected to the core network 30 via a predetermined interface (for example, an NG interface). More specifically, for example, each base station device 20 is connected to the UPF of the core network 30 via an NG-U interface in the U-plane, and is connected to the AMF of the core network 30 via an NG-C interface in the C-plane. Note that each base station device 20 may also be connected to the core network 30 via another interface with a different function or name.

[0027] The radio protocol architecture between the terminal device 10 and the base station device 20 will be described with reference to Fig. 2. The radio protocol architecture between the terminal device 10 and the base station device 20 and between the terminal device 10 and the core network 30 will be described with reference to Fig. 3.

Each of the above layers is terminated at base station device 20 on the network side.

[0029] As shown in Fig. 3, the C-plane protocol stack includes, from the bottom up, a physical (PHY) layer, a media access control (MAC) layer, a radio link control (RLC) layer, a packet data convergence protocol (PDCP) layer, a radio resource control (RRC) layer, and a non-access stratum (NAS). Each of the above layers except the non-access stratum is terminated at the base station device 20 on the network side. The non-access stratum is terminated at the AMF of the core network 30 on the network side.

[0048] The control unit 210 operates to execute various processes in the base station device 20 of this embodiment.

[0049] 1.2. Radio Resources The terminal device 10 and the base station device 20 communicate wirelessly with each other using radio resources in the frequency domain and the time domain. The radio resources will be described below.

[0050] The transmission method for downlink communication from the base station device 20 to the terminal device 10 is, for example, Orthogonal Frequency Division Multiplexing (OFDM) using a cyclic prefix (CP), that is, CP-OFDM. The transmission method for uplink communication from the terminal device 10 to the base station device 20 is, for example, the above-mentioned CP-OFDM or DFTS-OFDM in which CP-OFDM is applied after Transform Precoding that performs Discrete Fourier Transform (DFT) spreading.

[0051] A cyclic prefix is ​​a redundant signal that functions as a guard period (GP) to prevent inter-symbol interference and inter-carrier interference, and is inserted at the beginning of an OFDM symbol. There are two types of cyclic prefixes: a normal cyclic prefix and an extended cyclic prefix.

[0052] As radio resources in the frequency domain of OFDM, multiple subcarriers that are orthogonal to each other are used. The multiple subcarriers are arranged in the frequency domain at a predetermined subcarrier spacing (sub-carrier spacing, SCS) Δf. Multiple subcarrier spacings Δf may be applied in the communication system S1. The subcarrier spacing Δf is expressed by, for example, the following equation: Δf=2 μ 15[kHz]

[0053] Here, μ is an integer equal to or greater than 0 and can take on at least one of the following values: 0, 1, 2, 3, 4, 5, or 6. Therefore, the subcarrier spacing Δf [kHz] can take on at least one of the following values: 15, 30, 60, 120, 240, 480, or 960. Note that μ may also take on a value of 7 or greater.

[0054] In the time domain of OFDM, a layered radio frame structure is used as shown in Figure 8. One radio frame includes 10 subframes. Subframes are assigned subframe numbers that count up by one from 0 to 9. One radio frame is divided into two half frames. The time length of a radio frame is 10 ms, the time length of a half frame is 5 ms, and the time length of a subframe is 1 ms. These time lengths do not depend on the subcarrier spacing Δf.

[0055] One subframe includes one or more slots (slot(s)). The number Ns of slots included in one subframe depends on the value of μ mentioned above, and further on the subcarrier spacing Δf. The number Ns of slots is expressed by, for example, the following equation: Ns=2 μ

[0056] One slot contains multiple symbols. The number of symbols in one slot depends on the type of cyclic prefix. For example, if a normal cyclic prefix is ​​used, one slot contains 14 symbols. For example, if an extended cyclic prefix is ​​used, one slot contains 12 symbols.

[0057] As described above, the number of slots and the number of symbols included in each of a radio frame, half frame, and subframe, each of which has a fixed time length, are variable. Therefore, the time length of a slot and the time length of a symbol are also variable.

[0058] A resource element (RE) is a radio resource unit in the time-frequency domain consisting of one subcarrier and one symbol, and a resource block (RB) is a radio resource unit in the time-frequency domain consisting of 12 subcarriers and multiple symbols.

[0059] Each radio frame is assigned a system frame number (SFN), which counts up by one from 0 to 1023. SFN "0" corresponds to the initial SFN value, and SFN "1023" corresponds to the maximum SFN value. Therefore, SFN0 is assigned to the radio frame following a radio frame assigned SFN 1023. Since the time length of a radio frame is 10 ms, the time length of one cycle of the system frame number is 10240 ms (= 10.24 seconds).

[0060] Here, the base station device 20 may configure one or more serving cells for the terminal device 10. The serving cell may correspond to a component carrier in the downlink and / or a component carrier in the uplink. A technology in which one or more serving cells are configured and the base station device 20 and the terminal device 10 perform wireless communication may also be referred to as carrier aggregation.

[0061] Furthermore, the base station device 20 may configure one or more bandwidth parts (Bandwidth Parts, BWPs) for the terminal device 10 with respect to each of one or more serving cells. For example, a downlink bandwidth part (DL-BWP) may be configured in the downlink of one serving cell. Furthermore, an uplink bandwidth part (UL-BWP) may be configured in the uplink of one serving cell. Here, the DL-BWP may include an initial DL-BWP and / or a dedicated DL-BWP. Furthermore, the UL-BWP may include an initial UL-BWP and / or a dedicated UL-BWP. Hereinafter, BWP may include a DL-BWP and / or a UL-BWP.

[0062] 1.3. Channel and Control Information The terminal device 10 and the base station device 20 transmit and receive user data and control information to and from each other. The transmission and reception of control information in the downlink and uplink will be exemplified below.

[0063] The terminal device 10 and the base station device 20 transmit and receive user data and control information using a plurality of hierarchical channels. A physical channel is a channel used for physical communication between the terminal device 10 and the base station device 20. Examples of physical channels include a physical downlink control channel (PDCCH), a physical broadcast channel (PBCH), and a physical uplink control channel (PUCCH).

[0064] A transport channel is a channel located above a physical channel and is mapped to a physical channel in the PHY layer. Multiple transport channels may be mapped to one physical channel. Examples of transport channels include a Downlink Shared Channel (DL-SCH) and an Uplink Shared Channel (UL-SCH). For example, data in the downlink may also be referred to as DL-SCH data. Also, for example, data in the uplink may also be referred to as UL-SCH data. Here, DL-SCH data includes downlink user data. Also, UL-SCH data includes uplink user data.

[0065] A logical channel is a channel located above a transport channel and is mapped to a transport channel in the MAC layer. Multiple logical channels may be mapped to one transport channel, and one logical channel may be mapped to multiple transport channels. Logical channels are classified according to the characteristics of the information they transmit. Examples of logical channels include a Broadcast Control Channel (BCCH), a Common Control Channel (CCCH), and a Dedicated Control Channel (DCCH).

[0066] The base station device 20 transmits downlink control information (DCI) to the terminal device 10 using a PDCCH, which is a physical channel. The DCI includes information regarding downlink and uplink resource allocation for the terminal device 10, and control information for the terminal device 10. The DCI is mapped to the PDCCH and corresponds to Layer 1 signaling.

[0067] Here, one or more formats may be defined for transmission of DCI in the PDCCH. A format defined for transmission of DCI in the PDCCH may be referred to as a DCI format. For example, the DCI format may include a DCI format used for scheduling a Physical Downlink Shared Channel (PDSCH) (e.g., a format referred to as DCI format 1_0, DCI format 1_1, and / or DCI format 1_2). Furthermore, for example, the DCI format may include a DCI format used for scheduling a Physical Uplink Shared Channel (PUSCH) (e.g., a format referred to as DCI format 0_0, DCI format 0_1, and / or DCI format 0_2). Furthermore, the DCI format may include a DCI format not used for scheduling a PDSCH and / or a PUSCH. A DCI format used for scheduling a PDSCH and / or a PUSCH may be referred to as a scheduling DCI format. A DCI format that is not used for scheduling a PDSCH and / or a PUSCH may be referred to as a non-scheduling DCI format. In this embodiment, for ease of explanation, a "DCI format" may be simply referred to as a "PDCCH." Furthermore, a "DCI generated according to a DCI format" may be simply referred to as a "DCI format."

[0068] For example, the base station device 20 may configure frequency domain resources and / or time domain resources that the terminal device 10 monitors (i.e., monitors) a PDCCH candidate set. For example, the frequency domain resources that the terminal device 10 monitors the PDCCH candidate set may be referred to as a control resource set (CORESET). Furthermore, the time domain resources that the terminal device 10 monitors the PDCCH candidate set may be referred to as a search space set (SSS). The terminal device 10 may monitor the PDCCH candidate set in one or more CORESETs in the DL-BWP of a serving cell in which PDCCH monitoring is configured, according to the corresponding search space set. Here, monitoring may imply attempting to decode each of the PDCCH candidates according to the monitored DCI format. The above configuration may be referred to as blind decoding.

[0069] Here, a CRC (Cyclic Redundancy Check) scrambled with an RNTI (Radio Network Temporary Identifier) ​​may be added to DCI (or a DCI format) transmitted on the PDCCH. The CRC may also be referred to as a CRC parity bit. Multiple types of RNTIs are defined. For example, the base station device 20 may set each RNTI by transmitting an RRC message including at least one of information indicating a C-RNTI (Cell-RNTI), information indicating a MCS-C-RNTI (Modulation and Coding Scheme Cell-RNTI), and information indicating a CS-RNTI (Configured Scheduling-RNTI). In other words, a CRC scrambled with at least one of a C-RNTI, an MCS-C-RNTI, and a CS-RNTI may be added to DCI (or a DCI format) transmitted on the PDCCH.

[0070] The terminal device 10 may monitor (and / or receive) the PDCCH and detect (and / or receive) the DCI format.

[0071] The terminal device 10 transmits uplink control information (UCI) to the base station device 20 using the PUCCH, which is a physical channel. The UCI includes control information such as a scheduling request (SR), HARQ Ack / Nack, and channel state information (CSI). The UCI is mapped to the PUCCH or PUSCH and corresponds to layer 1 signaling.

[0072] The base station device 20 uses DL-SCH, which is a transport channel, to transmit a control element (CE) of the MAC layer to the terminal device 10. The downlink MAC CE is mapped to the PDSCH via DL-SCH and corresponds to Layer 2 signaling.

[0073] The terminal device 10 transmits a control element (CE) of the MAC layer to the base station device 20 using the UL-SCH, which is a transport channel. The uplink MAC CE includes control information such as a buffer status report (BSR). The uplink MAC CE is mapped to a PUSCH via the UL-SCH and corresponds to Layer 2 signaling.

[0074] The base station device 20 transmits (or broadcasts) system information (SI) to the terminal device 10 using the BCCH, which is a logical channel. The SI includes minimum system information (MSI) and other system information (OSI). The MSI includes a master information block (MIB) and system information block 1 (SIB1). The SIB1 may be referred to as remaining minimum system information (RMSI). The OSI includes system information blocks (SIB2 onward) other than SIB1. Of the BCCH, the MIB is mapped to the PBCH via the BCH (Broadcast CHannel), and the SIB is mapped to the PDSCH via the DL-SCH.

[0075] The base station device 20 transmits control information in the RRC layer to the terminal device 10 using a signaling radio bearer (SRB) established between the terminal device 10 and the base station device 20 in the RRC layer. Hereinafter, a message exchanged between the base station device 20 and the terminal device 10 in the RRC layer may be referred to as an RRC message. There are multiple types of SRBs (for example, SRB0, SRB1, SRB2, SRB3, and SRB4). SRBs are used for transmitting and receiving RRC messages as well as NAS messages including control information in the NAS layer. CCCH or DCCH is used to transmit RRC messages from the base station device 20 to the terminal device 10. The CCCH and DCCH are each mapped to the PDSCH via the DL-SCH. The RRC message corresponds to Layer 3 signaling.

[0076] As an example of a downlink RRC message, an RRC reconfiguration message will be described. The RRC reconfiguration message is an RRC message transmitted from the base station device 20 to the terminal device 10 using SRB1 or SRB3. A DCCH is used to transmit the RRC reconfiguration message. The RRC reconfiguration message is used to perform reconfiguration or modification of the connection between the base station device 20 and the terminal device 10.

[0077] The terminal device 10 uses the above-mentioned SRB to transmit an RRC message to the base station device 20. A CCCH or a DCCH is used to transmit the RRC message from the terminal device 10 to the base station device 20. The CCCH and DCCH are each mapped to a PUSCH via a UL-SCH. The RRC message corresponds to Layer 3 signaling.

[0078] As an example of an uplink RRC message, a user equipment capability information (UECapabilityInformation) message will be described. The user equipment capability information message is an RRC message transmitted from the terminal device 10 to the base station device 20 using SRB1. A DCCH is used to transmit the user equipment capability information message. The user equipment capability information message is used to notify the base station device 20 of information related to the radio access capability of the terminal device 10.

[0079] As an example of an uplink RRC message, a user equipment assistance information (UE Assistance Information) message will be described. The user equipment assistance information message is an RRC message transmitted from the terminal device 10 to the base station device 20 using SRB1 or SRB3. DCCH is used to transmit the user equipment assistance information message. The user equipment assistance information message is used to notify the base station device 20 of various information related to the terminal device 10 (UE assistance information).

[0080] 1.4. Uplink Scheduling 1.4.1. Dynamic Grant (DG) DG is a scheduling method for allocating radio resources for a PUSCH in accordance with an uplink grant procedure. The base station device 20 transmits an uplink grant to the terminal device 10 on the PDCCH. The terminal device 10 transmits the PUSCH in accordance with the uplink grant. For example, the base station device 20 may allocate radio resources for the PUSCH using a DCI format with a CRC scrambled by the C-RNTI and / or MCS-C-RNTI (i.e., a DCI format used for scheduling the PUSCH), and the terminal device 10 may perform uplink transmission using the allocated radio resources for the PUSCH. Here, a new data indicator included in the DCI format to which the CRC scrambled by the C-RNTI and / or MCS-C-RNTI is added may be set to 0 or 1. Furthermore, the base station device 20 may allocate radio resources for the PUSCH using a DCI format with a CRC scrambled by the CS-RNTI (i.e., a DCI format used for scheduling the PUSCH), and the terminal device 10 may perform uplink transmission using the allocated radio resources for the PUSCH. Here, a new data indicator included in the DCI format with a CRC scrambled by the CS-RNTI may be set to 1.

[0081] 1.4.2. Configured Grant (CG) CG is a scheduling method for allocating radio resources for PUSCH without the above-mentioned dynamic uplink grant procedure. The base station device 20 transmits an RRC message including CG parameters to the terminal device 10. The CG parameters are included in a ConfiguredGrantConfig IE, which is an example of an RRC information element (IE).

[0082] For example, the base station device 20 may transmit to the terminal device 10 an RRC message including parameters related to CG for a certain serving cell (i.e., ConfiguredGrantConfig IE). That is, the parameters related to CG (i.e., ConfiguredGrantConfig IE) may be configured for each of one or more serving cells. Furthermore, the base station device 20 may transmit to the terminal device 10 an RRC message including parameters related to CG for a certain UL-BWP (i.e., ConfiguredGrantConfig IE). That is, the parameters related to CG (i.e., ConfiguredGrantConfig IE) may be configured for each of one or more UL-BWPs. The terminal device 10 may identify the parameters related to CG for each of one or more UL-BWPs (i.e., ConfiguredGrantConfig IE).

[0083] The ConfiguredGrantConfig IE includes a parameter "periodicity" related to the periodicity of transmission using the PUSCH. Note that the parameter "periodicity" is set in units of the number of slots or the number of symbols. Alternatively, the parameter "periodicity" may be set in units of frames per second (FPS).

[0084] The CG sets one or more transmission occasions for the PUSCH. The terminal device 10 may transmit the PUSCH at the transmission opportunity. Here, the transmission opportunity may be rephrased as a resource (for example, a PUSCH resource). Note that the terminal device 10 supports one TB (Transport Block) at one transmission opportunity. That is, one TB is transmitted at one transmission opportunity.

[0085] CG includes two types: Type 1 and Type 2. Each of Type 1 and Type 2 will be explained below.

[0086] (1) Type 1 In Type 1, the terminal device 10 transmits a signal (for example, transmission on a PUSCH) at a set period without being triggered by DCI (for example, a DCI format used for scheduling a PUSCH).

[0087] As shown in FIG. 9, the communication unit 220 of the base station device 20 transmits an RRC message including CG parameters to the terminal device 10 (S901).

[0088] The control unit 110 of the terminal device 10 performs a periodic transmission operation of the PUSCH in accordance with the CG parameters (S902). For example, the terminal device 10 may store an RRC message including the CG parameters as a configured uplink grant. Here, the RRC message including the CG parameters used for scheduling the PUSCH is also referred to as an uplink grant. Furthermore, after the uplink grant is configured for CG type 1, the terminal device 10 may consider that the uplink grant occurs sequentially (repeatedly) in an SFN and / or slot number that satisfies a predetermined formula. That is, the terminal device 10 may perform transmission of the PUSCH by considering that the stored uplink grant occurs sequentially in an SFN and / or slot number that satisfies a predetermined formula.

[0089] The control unit 210 of the base station device 20 performs a periodic reception operation of the PUSCH (S903). The control unit 210 may perform reception of the PUSCH by assuming that the uplink grants stored in the terminal device 10 are sequentially generated (repeated) for the SFN and / or slot number that satisfies a predetermined formula.

[0090] Note that, for one or more serving cells or one or more UL-BWPs, multiple CGs may be configured in the terminal device 10. For example, the base station device 20 may transmit an RRC message including parameters related to a first CG (e.g., first CG setting) and parameters related to a second CG (e.g., second CG setting) to the terminal device 10. The terminal device 10 may perform transmission of a first PUSCH associated with the first CG (e.g., first CG setting) and transmission of a second PUSCH associated with the second CG (e.g., second CG setting).

[0091] (2) Type 2 In Type 2, the terminal device 10 transmits a signal (e.g., transmission on a PUSCH) at a set period in response to activation by DCI scrambled with CS-RNTI (e.g., a DCI format used for scheduling a PUSCH).

[0092] 10, the communication unit 220 of the base station device 20 transmits an RRC message including CG parameters to the terminal device 10 (S1001). Next, the communication unit 220 transmits DCI scrambled with the CS-RNTI to the terminal device 10 (S1002). This activates the periodic transmission operation by the terminal device 10 using the PUSCH.

[0093] The control unit 110 of the terminal device 100 performs a periodic transmission operation of the PUSCH in accordance with the CG parameters and / or the DCI (S1003). For example, when the DCI to which a CRC scrambled by the CS-RNTI is added (i.e., the DCI used for scheduling the PUSCH) indicates CG activation (i.e., when the PDCCH indicates CG activation), the terminal device 10 may store the DCI as a configured uplink grant. Here, the DCI used for scheduling the PUSCH (DCI format) is also referred to as an uplink grant. Furthermore, the case where the DCI indicates CG activation may include a case where predetermined information included in the DCI (e.g., each of one or more information fields) is set to a predetermined value. For example, the case where the DCI indicates CG activation may include a case where a new data indicator included in the DCI is set to 0. Furthermore, the terminal device 10 may consider that the uplink grant occurs sequentially (is repeated) in the SFN and / or slot number that satisfies a predetermined formula after the uplink grant is set for CG type 2. That is, the terminal device 10 may perform transmission of the PUSCH by considering that the stored uplink grant occurs sequentially in the SFN and / or slot number that satisfies the predetermined formula.

[0094] The control unit 210 of the base station device 20 performs a periodic reception operation of the PUSCH (S1004). The control unit 210 may perform reception of the PUSCH by assuming that the uplink grants stored in the terminal device 10 are sequentially generated (repeated) for the SFN and / or slot number that satisfies a predetermined formula.

[0095] Note that, for one or more serving cells or one or more UL-BWPs, multiple CGs may be configured in the terminal device 10. For example, the base station device 20 may transmit an RRC message including parameters related to a first CG (e.g., first CG setting) and parameters related to a second CG (e.g., second CG setting) to the terminal device 10. When the first CG (e.g., first CG setting) is activated by a DCI, the terminal device 10 may transmit a first PUSCH associated with the first CG (e.g., first CG setting). When the second CG (e.g., second CG setting) is activated by a DCI, the terminal device 10 may transmit a second PUSCH associated with the second CG (e.g., second CG setting). For example, in order to activate each of the transmissions of multiple PUSCHs, information indicating an index of the CG setting (e.g., a value of the information indicating the index of the CG setting) may be included in the DCI. For example, when the terminal device 10 receives DCI including information indicating an index of a first CG setting (for example, information indicating index "0" of the first CG setting), the terminal device 10 may execute (or activate) transmission of a PUSCH based on the first CG setting. Also, when the terminal device 10 receives DCI including information indicating an index of a second CG setting (for example, information indicating index "1" of the second CG setting), the terminal device 10 may execute (or activate) transmission of a PUSCH based on the second CG setting. Here, the value of the information indicating the index of the CG setting (for example, the value of the information indicating the index of the first CG setting and / or the value of the information indicating the index of the second CG setting) may be set in a field of information indicating an HARQ process number.

[0096] 1.5. Resource Allocation In the DG and CG, the terminal device 10 may receive information for determining resource allocation for uplink transmission (hereinafter also referred to as information related to a table) from the base station device 20. For example, the above table is a TDRA (Time Domain Resource Assignment) table. Hereinafter, the above table is referred to as a "first table." Furthermore, the above information is referred to as "first table information." For example, the "first table information" may be included in parameters related to the PUSCH. That is, the base station device 20 may transmit an RRC message including one or more parameters for TDRA for PUSCH transmission (e.g., information related to a table), and the terminal device 10 may determine resources in the time domain for PUSCH transmission based on the one or more parameters for TDRA. Hereinafter, a case will be described in which one or more parameters for TDRA are defined as a table, but the one or more parameters for TDRA may be defined in any format. For example, an index (and / or an order) may be defined corresponding to each of one or more parameters for TDRA, and may correspond to an index in a table described later.

[0097] In the first table, one index (or value) is associated with one PUSCH transmission opportunity, specifically, one or more parameters related to resources for PUSCH transmission.

[0098] For example, the first table may include at least one of the following parameters (a1) to (a3). (a1) k2: Information related to a slot in which uplink transmission (i.e., PUSCH transmission) is performed. Specifically, k2 may indicate an offset between a slot in which an RRC message or DCI is received and a slot in which PUSCH transmission is performed. Here, reception of an RRC message or DCI may include the occurrence of an uplink grant. Furthermore, performance of uplink transmission (i.e., PUSCH transmission) may include an uplink transmission opportunity. That is, the offset indicated by k2 may include an offset between a slot in which an RRC message or DCI is received and a PUSCH transmission opportunity. A default value may be used as k2 according to the SCS. (a2) SLIV (Start and Length Indicator Value): Information indicating a combination of a start symbol position S in a slot in which uplink transmission (i.e., PUSCH transmission) is performed and a consecutive symbol length L from the start symbol position S. The slot in which uplink transmission (i.e., PUSCH transmission) is performed may include a slot of an uplink transmission opportunity (i.e., PUSCH transmission opportunity). Instead of the SLIV, the start symbol position S and the symbol length L may be indicated separately. (a3) Mapping Type: Information indicating a mapping type for uplink transmission (i.e., transmission of a PUSCH). The mapping type includes Type A and Type B.

[0099] Similarly, the first table information may include at least one of the parameters (a1) to (a3) ​​above. The base station apparatus 20 may transmit an RRC message including the first table information to the terminal apparatus 10. The first table information may be included in parameters related to the PUSCH (for example, PUSCH-ConfigCommon IE). The terminal apparatus 10 sets the first table based on the first table information.

[0100] The first table information may be set for each cell, each UE, and / or each DCI format. That is, multiple first tables may be set. Note that a default table may be used as the first table.

[0101] The table that is actually applied (or selected) from among the plurality of first tables may be determined based on the following (b1) to (b4). (b1) DCI format (b2)RNTI (b3) PDCCH Search Space (b4) Information on whether the first table is set for each cell, each UE, and / or each DCI format

[0102] An example in which a cell-specific first table is configured will be described below. The cell-specific first table may be configured using a PUSCH-ConfigCommon IE included in an RRC message. The base station device 20 transmits an RRC message including a PUSCH-ConfigCommon IE to the terminal device 10. The PUSCH-ConfigCommon IE includes one or more PUSCH-TimeDomainResourceAllocationList IEs as first table information. The PUSCH-TimeDomainResourceAllocationList IE includes k2, mappingType, and startSymbolAndLength. k2 corresponds to (a1) above. mappingType corresponds to (a3) ​​above. startSymbolAndLength corresponds to (a2) above.

[0103] As shown in Fig. 11, the terminal device 10 may set the first table based on first table information. The first table includes information indicating a row index for referring to each row. In the example of Fig. 11, the row index is associated with parameters (a1) to (a3). Note that j shown as the value of k2 is the parameter μ representing the SCS of the PUSCH. PUSCH is a value determined in accordance with the above. That is, j indicated as the value of k2 is determined based on the SCS set for the UL-BWP in which transmission of the corresponding PUSCH is executed. For example, the base station apparatus 20 may transmit to the terminal apparatus 10 an RRC message including information indicating the SCS for each of one or more UL-BWPs. The base station apparatus 20 transmits to the terminal apparatus 10 information indicating the row index m.

[0104] In the case of CG type 1, the base station device 20 transmits an RRC message including information indicating row index m to the terminal device 10. For example, the information indicating row index m may be included in a parameter related to the CG (i.e., a ConfiguredGrantConfig IE). The information indicating row index m may be indicated by a timeDomainAllocation IE included in the ConfiguredGrantConfig IE. Note that the size (i.e., the number of bits or bit width) of the information (IE) indicating row index m may be determined based on, for example, the number of entries in the first table. In the example of FIG. 11, the number of entries in the first table is 30, so the size of the information indicating row index m may be 5 bits. When receiving an RRC message including information indicating row index m from the base station device 20, the terminal device 10 may refer to row index m+1 of the first table. The terminal device 10 may determine uplink transmission resources using parameters (a1) to (a3) ​​associated with row index m+1 of the first table.

[0105] In the case of CG type 2, the base station apparatus 20 transmits DCI including information indicating row index m (i.e., an information field set to a value indicating row index m) to the terminal apparatus 10. That is, the information indicating row index m may be indicated by a value set in the TDRA field of the DCI. Here, the size of the TDRA field (i.e., the number of bits or bit width) may be determined based on, for example, the number of entries in the first table. In the example of FIG. 11, the number of entries in the first table is 30, so the size of the TDRA field may be 5 bits. When receiving DCI including information indicating row index m from the base station apparatus 20, the terminal apparatus 10 may refer to row index m+1 of the first table. The terminal apparatus 10 may determine uplink transmission resources using parameters (a1) to (a3) ​​associated with row index m+1 of the first table.

[0106] Furthermore, in the DG, the base station apparatus 20 can schedule multiple transmission opportunities for the PUSCH using a single DCI. The terminal apparatus 10 may receive, from the base station apparatus 20, information on a table for determining resource allocation for uplink transmission. The above table is a TDRA table, and is hereinafter referred to as a "second table." Furthermore, the above information is referred to as "second table information." That is, the second table information may include at least one of the above parameters (a1) to (a3). For example, the "second table information" may be included in parameters related to the PUSCH.

[0107] In the second table, one index (or value) is associated with one or more PUSCH transmission opportunities, specifically, one or more parameters related to resources for the transmission of one or more PUSCHs.

[0108] For example, the base station device 20 may transmit an RRC message including second table information to the terminal device 10. The second table information may be included in parameters related to the PUSCH (for example, a PUSCH-Config IE). Note that the second table information may be set for each cell, for each UE, and / or for each DCI format. That is, multiple second tables may be set. Note that a default table may be used as the second table.

[0109] For example, the PUSCH-Config IE may include a pusch-TimeDomainAllocationListForMultiPUSCH IE as second table information. The pusch-TimeDomainAllocationListForMultiPUSCH IE may include one or more PUSCH-TimeDomainResourceAllocation IEs. The PUSCH-TimeDomainResourceAllocation IE may include k2 and one or more puschAllocationList IEs. The puschAllocationList IE may include at least one of mappingType, startSymbolAndLength, startSymbol, and length. k2 corresponds to (a1) above. The mappingType corresponds to (a3) ​​above. The startSymbolAndLength, startSymbol, and length correspond to (a2) above. In this example, one k2 may be associated with multiple PUSCH-Allocation IEs. That is, one k2 may be set in common for multiple PUSCH-Allocation IEs. In this case, k2 may indicate a slot including the first transmission opportunity among 2 to 8 consecutive PUSCH transmission opportunities. That is, the terminal device 10 may perform uplink transmission in consecutive PUSCH transmission opportunities based on the second table information.

[0110] As shown in FIG. 12, the terminal device 10 may set a second table based on second table information. The second table includes information indicating a row index for referring to each row. In the example of FIG. 12, a certain row index is associated with multiple transmission opportunities of the PUSCH. For example, when row index "10" in the second table is indicated by information indicating the row index included in the DCI (for example, a value set in the information indicating the row index), multiple transmission opportunities corresponding to row index "10" are scheduled. Specifically, when row index "10" is indicated, the terminal device 10 may use four parameter sets corresponding to four transmission opportunities, respectively. Parameters (a2) and (a3) ​​are set individually for each of the four transmission opportunities. Note that parameter (a1) is set commonly for the four transmission opportunities.

[0111] In another example, the parameter (a1) may be set individually for each of the four transmission opportunities. In this case, the parameter extendedK2 included in the PUSCH-Allocation IE may be used. That is, the base station apparatus 20 may set the parameters (a1) to (a3) ​​individually or commonly for multiple PUSCH transmission opportunities.

[0112] The base station apparatus 20 transmits DCI including information indicating row index m to the terminal apparatus 10. The row index m may be indicated by a value set in the TDRA field of the DCI. The size of the TDRA field may be determined based on, for example, the number of entries in the second table. For example, when the format of the DCI is DCI format 0_1 ​​and / or DCI format 0_2, the size of the TDRA field may be determined based on the number of entries in the second table. In the example of FIG. 12, the number of entries in the second table is 15, so the size of the TDRA field may be 4 bits. When the terminal apparatus 10 receives DCI including information indicating row index m from the base station apparatus 20, it may refer to row index m+1 of the second table. The terminal apparatus 10 may determine uplink transmission resources using parameters (a1) to (a3) ​​associated with row index m+1 of the second table.

[0113] For example, the base station device 20 transmits DCI including information set to a value indicating row index "9" to the terminal device 10. The terminal device 10 refers to the row with row index "10" in the second table shown in FIG. 12. This row is associated with four parameter sets. Therefore, the terminal device 10 determines (or decides) that four transmission opportunities for the PUSCH have been scheduled. The terminal device 10 determines uplink transmission resources using the four parameter sets associated with row index "10".

[0114] 1.6. Transmission of UCI The terminal device 10 may transmit UCI on a PUSCH scheduled by a CG (that is, a CG PUSCH).

[0115] NR-U (unlicensed) is a 5G specification that uses unlicensed spectrum channels, which may also be referred to as shared spectrum channels.

[0116] In NR-U, UCI transmitted on a PUSCH scheduled by a CG is also referred to as "CG-UCI." The CG-UCI may include specific fields. For example, assume that the parameter cg-RetransmissionTimer of an upper layer (i.e., the RRC layer) is configured. In this case, the CG-UCI may include at least one of fields (c1) to (c4). (c1) HARQ Process Number (c2) Redundancy Version (RV) (c3) New Data Indicator (NDI) (c4)Channel Occupancy Time(COT) sharing information

[0117] When the upper layer parameter cg-UCI-Multiplexing is set, the CG-UCI may include the following field (c5) in addition to (c1) to (c4). (c5) HARQ-Ack bit

[0118] 1.7. Extended Reality (XR) This section explains the characteristics of traffic generated in XR. In XR, multiple types of data (video data, audio data, user data, control data, etc.) are transmitted and received in parallel. The multiple data streams corresponding to the above data each have different traffic characteristics and quality of service (QoS) requirements.

[0119] The timing of sending and receiving the above data may experience time shifts, which can be expressed as jitter, variability, or fluctuation, due to factors such as video and audio encoding and network delays.

[0120] Reference 1 states that the following definitions can be introduced regarding transmission and reception in XR: [Reference 1] 3GPP TR 23.700-60 V1.1.0 (2022-09)

[0121] PDU set: A set of one or more PDUs that carry a payload of one unit of information generated at the application level, which corresponds to, for example, a frame or a video slice in an XR service. Data Burst: A set of data multiple PDUs generated and transmitted by an application in a short period of time.

[0122] Furthermore, in XR, a Packet Delay Budget (PDB) requirement is being considered as one of the above QoS requirements. The PDB is the upper bound of the packet delay time allowed between the terminal device 10 and the UPF. Reference 1 also describes that the following new QoS parameters may be introduced: PDU-Set Delay Budget (PSDB): This is the upper bound of the delay time of a PDU set that is allowed between the terminal device 10 and the UPF. PDU-Set Error Rate (PSER): The upper bound of the error rate calculated between a PDU set processed by a sender and all PDUs in the PDU set that are not successfully delivered to the corresponding upper layer of the receiver.

[0123] 1.8. CG Expansion XR is expected to be operated under the various requirements described above. Accordingly, for uplink transmission from a terminal device, the use of CG-based scheduling, rather than DG-based scheduling, is being considered. As shown in FIG. 13 , conventionally, one transmission opportunity is set in a single CG period. The period corresponds to the periodicity, which is the CG parameter (i.e., a parameter related to CG) described above. As described above, the base station device 20 may transmit an RRC message containing CG parameters including information indicating the periodicity and / or offset, and set the periodicity and / or offset for the transmission of the CG PUSCH. Furthermore, the terminal device 10 may perform periodic transmission of the CG PUSCH in accordance with the information indicating the periodicity and / or offset included in the RRC message. Here, one transmission opportunity may include a transmission opportunity corresponding to the transmission of one transport block. Furthermore, multiple transmission opportunities may include transmission opportunities corresponding to the transmission of one or multiple transport blocks.

[0124] The configuration in Fig. 13 may not be able to satisfy the XR requirements. Therefore, in this embodiment, multiple transmission opportunities are set in a single period for PUSCH as shown in Fig. 14. In the example of Fig. 14, the number of transmission opportunities included in one period is Nt=3.

[0125] In such a configuration, the terminal device 10 may not use at least one of a plurality of transmission opportunities (for example, a plurality of transmission opportunities included in one period) for uplink transmission. Hereinafter, such an unused transmission opportunity will be referred to as an "unused occasion" or an "unused transmission occasion."

[0126] The terminal device 10 transmits information about unused opportunities among a plurality of transmission opportunities to the base station device 20. Note that such information about unused opportunities may be referred to as a "dynamic indication of unused opportunities."

[0127] For example, the terminal device 10 transmits UCI including information about unused opportunities to the base station device 20. The UCI including information about unused opportunities may be referred to as UTO-UCI (Unused Transmission Occasion - Uplink Control Information). The terminal device 10 may transmit UCI using at least one of a plurality of transmission opportunities set by the CG (i.e., CG PUSCH). Alternatively, the terminal device 10 may transmit UCI using resources other than the CG PUSCH (e.g., PUCCH resources). In such a configuration, a procedure is required in which the terminal device 10 and / or the base station device 20 determine the size (i.e., the number of bits or bit width) of the information about unused opportunities.

[0128] In this embodiment, the terminal device 10 receives configuration information related to multiple transmission opportunities included in one period in a CG. Hereinafter, for simplicity, the "configuration information related to multiple transmission opportunities included in one period in a CG" will be simply referred to as "configuration information."

[0129] The configuration information may be configured for each of one or more serving cells. In another example, the configuration information may be configured for each of one or more UL-BWPs. Furthermore, the configuration information may be configured for each of one or more CGs (i.e., CG configurations). For example, the configuration information may be configured for each of one or more Type 1 CG configurations. Furthermore, the configuration information may be configured for each of one or more Type 2 CG configurations. For example, the base station device 20 may transmit an RRC message including the configuration information. The terminal device 10 may receive the configuration information included in the RRC message. For example, the base station device 20 may transmit an RRC message including information for determining the number of bits of information regarding unused opportunities (for example, information indicating the number of bits of information regarding unused opportunities). Furthermore, the terminal device 10 may determine the number of bits of information regarding unused opportunities based on the information for determining the number of bits of information regarding unused opportunities included in the RRC message. For example, the number of bits of information regarding unused opportunities may be the number of bits of information regarding unused opportunities in one period. Furthermore, as will be described later, the number of bits of information regarding unused opportunities may be the number of bits of information regarding unused opportunities in multiple periods.

[0130] The terminal device 10 uses the configuration information to determine the size (i.e., the number of bits or bit width) of the information on the unused opportunities. Similarly, the base station device 20 uses the configuration information to determine (or set) the size of the information on the unused opportunities. That is, the configuration information may be used to determine (or set) the size of the information on the unused opportunities.

[0131] Hereinafter, first to fourth aspects will be described as aspects of the process for determining the size of information related to unused opportunities.

[0132] (1) First aspect The configuration information may include table information for setting up a table regarding resources for multiple transmission opportunities included in one period in the CG, and / or indication information indicating an index (or value) for referencing the table.

[0133] Hereinafter, the above table will be referred to as a "third table." The third table may be a TDRA table. Also, the above table information will be referred to as "third table information." In the third table, one index (or value) is associated with one or more PUSCH transmission opportunities.

[0134] Specifically, in the third table, one index is associated with one or more parameters. The parameters are parameters related to resources of transmission opportunities, and may include, for example, at least one of the following (d1) to (d7): (d1) Information regarding a slot in which uplink transmission (i.e., PUSCH transmission) is performed. Specifically, (d1) may be an offset between a slot in which an RRC message or DCI is received and a slot in which PUSCH transmission is performed. Here, reception of an RRC message or DCI may include the occurrence of an uplink grant. Furthermore, performance of uplink transmission (i.e., PUSCH transmission) may include an uplink transmission opportunity. That is, the offset indicated by k2 may include an offset between a slot in which an RRC message or DCI is received and a PUSCH transmission opportunity. For example, (d1) may be k2 in the above (a1). (d2) Starting symbol of uplink transmission (i.e., PUSCH transmission). The starting symbol of uplink transmission (i.e., PUSCH transmission) may include the starting symbol of an uplink transmission opportunity (i.e., PUSCH transmission opportunity). Specifically, (d2) may be the starting symbol position S of (a2) above. (d3) The length from the start symbol. The length from the start symbol may include the length of the uplink transmission opportunity (i.e., the PUSCH transmission opportunity) from the start symbol. Specifically, (d2) may be the symbol length L of (a2) above. Note that SLIV may be used as a combination of (d2) and (d3). (d4) Mapping type of uplink transmission (i.e., PUSCH transmission). Specifically, (d4) may be the mapping type of (a3) ​​above. That is, the mapping type may include Type A and Type B. (d5) Redundancy Version (RV): Indicates the number of a redundancy version corresponding to UL-SCH information (uplink data, uplink transmission opportunity, or PUSCH transmission). For example, when a redundancy version number is set, one transport block may be repeatedly transmitted in one or more PUSCH transmission opportunities according to the redundancy version number. (d6) Information regarding offsets (or gaps) between multiple uplink transmissions (i.e., multiple PUSCH transmissions). The information may include a length (or a period) between multiple uplink transmissions. The information may also include an offset (gap, length, or period) between multiple uplink transmission opportunities (i.e., PUSCH transmission opportunities). For example, the offset may be indicated by the number of slots and / or the number of symbols. Specifically, when three PUSCH transmission opportunities (a first transmission opportunity, a second transmission opportunity, and a third transmission opportunity) are configured in a certain CG period, the offset value between the first transmission opportunity and the second transmission opportunity and / or the offset value between the second transmission opportunity and the third transmission opportunity may be indicated. For example, a certain offset value may be configured, and the offset value may be commonly applied as the offset between the first transmission opportunity and the second transmission opportunity and the offset between the second transmission opportunity and the third transmission opportunity. Furthermore, if an offset is not set, the terminal device 10 may perform uplink transmission (that is, PUSCH transmission) at multiple consecutive PUSCH transmission opportunities. (d7) Information regarding an offset for determining the position of each slot and / or symbol of one or more uplink transmission opportunities. The information may include an offset for determining the position of each of multiple uplink transmissions (i.e., PUSCH transmissions). The offset may be the fifth information (e.g., timeDomainOffset) described below. For example, the offset may be a parameter used in a predetermined formula for determining the position of each slot and / or symbol of one or more uplink transmission opportunities.

[0135] Similarly, the third table information may include at least one parameter of (d1) to (d7). The terminal device 10 sets the third table using the third table information. For example, when the third table information is included in an RRC message, the terminal device 10 may perform PUSCH transmission based on the third table information. That is, when the third table information is included in an RRC message, the terminal device 10 may perform PUSCH transmission at one or more PUSCH transmission opportunities in one CG period. That is, when the third table information is included in an RRC message, the terminal device 10 may transmit one or more transport blocks in one CG period. Here, when the third table information is not included in an RRC message, the terminal device 10 may perform PUSCH transmission at one transmission opportunity in one CG period. That is, when the third table information is not included in an RRC message, the terminal device 10 may transmit one transport block in one CG period.

[0136] Furthermore, the terminal device 10 may transmit a PUSCH based on third table information included in each of a plurality of CG settings. Here, when transmissions of a plurality of PUSCHs collide, the terminal device 10 may transmit any one of the PUSCHs. That is, when transmissions of a plurality of PUSCHs collide, the terminal device 10 may transmit any one of the transport blocks. Here, a case where transmissions of a plurality of PUSCHs collide may include a case where transmissions of a plurality of PUSCHs occur in the same time domain resource (for example, slot and / or symbol). Also, a case where transmissions of a plurality of PUSCHs collide may include a case where transmission opportunities for a plurality of PUSCHs are set in the same time domain resource (for example, slot and / or symbol).

[0137] For example, when a plurality of PUSCH transmissions collide, the terminal device 10 may determine the PUSCH transmission to be performed (or the transmission opportunity to be used for the PUSCH transmission) based on information indicating an index included in the CG configuration (i.e., the index of the CG configuration). For example, assume that one or more first PUSCH transmissions (or first PUSCH transmission opportunities) are configured using a first CG configuration (i.e., the parameters of the first CG) including an index "0", and one or more second PUSCH transmissions (or second PUSCH transmission opportunities) are configured using a second CG configuration (i.e., the parameters of the second CG) including an index "1". When a first PUSCH transmission and a second PUSCH transmission collide, the terminal device 10 may perform one or more PUSCH transmissions based on the first CG configuration including the index "0". That is, when multiple PUSCH transmissions collide, the terminal device 10 may transmit one or multiple PUSCHs according to the parameters included in the CG setting with the smallest (or largest) index value.

[0138] Furthermore, for example, the base station device 20 may transmit an RRC message including information indicating the priority of a CG setting. For example, information indicating the priority of a CG setting may be set for each CG setting (or may be included in each CG setting). When transmissions of multiple PUSCHs collide, the terminal device 10 may transmit one or more PUSCHs based on the priority of the CG setting. For example, when transmissions of multiple PUSCHs collide, the terminal device 10 may transmit one or more PUSCHs in accordance with parameters included in the CG setting with the highest (or lowest) priority of the CG setting.

[0139] Furthermore, the terminal device 10 may transmit information indicating the redundancy version number corresponding to the UL-SCH information transmitted in the PUSCH. Specifically, for example, when the terminal device 10 has UL-SCH information for the first transmission opportunity (there is UL-SCH information), the terminal device 10 may include (by mapping or multiplexing) information indicating the redundancy version number "0" in the PUSCH resource for the first transmission opportunity. Furthermore, when the terminal device 10 does not have UL-SCH information for the first transmission opportunity (there is no UL-SCH information) and has UL-SCH information for the second transmission opportunity, the terminal device 10 may include information indicating the redundancy version number "0" in the PUSCH resource for the second transmission opportunity.

[0140] The third table information may be set for each cell, each UL-BWP, each UE, and / or each DCI format. That is, a plurality of third tables (i.e., a plurality of pieces of third table information) may be set. A default table may be used as the third table.

[0141] A table that is actually applied (or selected) from among a plurality of third tables may be determined based on the following (e1) to (e4). That is, third table information may be set for each DCI format (e.g., DCI format 0_0, DCI format 0_1, and / or DCI format 0_2) used for scheduling the PUSCH. That is, the terminal device may determine corresponding third table information (e.g., parameters for TDRA) based on the DCI format used for scheduling (and / or activating) the transmission of the PUSCH. (e1) DCI format (e2)RNTI (e3) PDCCH search space (e4) Information on whether the third table is set for each cell, each UL-BWP, each UE, and / or each DCI format

[0142] At least one of the above parameters included in the third table is set individually for each of multiple transmission opportunities included in one period. For example, an index received as instruction information may be associated with multiple parameters (or multiple parameter sets) corresponding to each of multiple transmission opportunities. Here, the number of parameters associated with the index corresponds to the number of transmission opportunities Nt. Therefore, the terminal device 10 determines the size of the information about unused opportunities based on the number of parameters (or the number of parameter sets) associated with the index. For example, the terminal device 10 may determine the size of the information about unused opportunities based on the number of at least one of the parameters (d1) to (d7) above. That is, the terminal device 10 may determine the size of the information about unused opportunities based on the number of entries of at least one of the parameters (d1) to (d7) above (i.e., the number of parameters included (or entered) in the third table information).

[0143] Here, the size of the information on unused opportunities may be determined based on the number of transmission opportunities Nt and the number of periods (i.e., CG periods) Np. That is, the information on unused opportunities may be used for PUSCH transmission opportunities in multiple periods. For example, the base station device 20 may transmit an RRC message including information indicating the number of periods Np for determining the size of the information on unused opportunities. For example, the terminal device 10 may determine the size of the information on unused opportunities by multiplying the number of transmission opportunities Nt by the number of periods Np. Specifically, for example, when "3" is specified as the number of transmission opportunities Nt and "2" is specified as the number of periods Np, 6 bits of information on unused opportunities (i.e., the number of bits obtained by multiplying the number of transmission opportunities Nt "3" by the number of periods Nt "2") may be used.

[0144] As described above, the base station device 20 may transmit an RRC message including one or more parameters (for example, one or more parameters included in the third table information) and set one or more transmission opportunities in one period for the terminal device 10. When the RRC message includes one or more parameters (for example, one or more parameters included in the third table information), the terminal device 10 may transmit a PUSCH at one or more transmission opportunities in one period.

[0145] Here, the base station device 20 may transmit an RRC message including information used to instruct transmission of information related to unused opportunities. That is, the base station device 20 may separately set transmission of PUSCH in one or more transmission opportunities and transmission of information related to unused opportunities. The terminal device 10 may transmit the information related to unused opportunities when the RRC message includes information used to instruct transmission of information related to unused opportunities (for example, the information related to unused opportunities may be included in the PUSCH resource (mapping or multiplexing)). For example, the terminal device 10 may transmit the information related to unused opportunities when the RRC message includes one or more parameters (for example, one or more parameters included in the third table information) and information used to instruct transmission of information related to unused opportunities.

[0146] The information about the unused opportunities may be represented as a sequence. Alternatively, the information may be represented as a bit string (e.g., a bitmap). That is, the sequence may be rephrased as a bit string. For example, the information may be represented as a bit string, and each bit of the bit string corresponds to each of a plurality of transmission opportunities, and may be used as information about the unused opportunities (i.e., dynamic indication). Details of the above sequence will be described later.

[0147] The base station device 20 determines the size of the information relating to unused opportunities based on the setting information (that is, the third table information and the instruction information) in the same manner as above.

[0148] The following describes specific procedures for CG Type 1 and Type 2. It is assumed that three transmission opportunities are set in one period, as in the example of FIG.

[0149] -Type 1 As shown in FIG. 15, the communication unit 220 of the base station device 20 transmits an RRC message including parameters related to the PUSCH to the terminal device 10 (S1501). The parameters related to the PUSCH include third table information. The parameters related to the PUSCH may be a PUSCH-Config IE. The third table information may be included in the PUSCH-Config IE. Note that the third table information may be included in an IE other than the PUSCH-Config IE. The parameters related to the PUSCH may include parameters related to the CG including the third table information.

[0150] The communication unit 220 transmits an RRC message including parameters related to CG to the terminal device 10 (S1502). The parameters related to CG include information indicating a row index m for referencing the third table. The parameters related to CG may be a ConfiguredGrantConfig IE. The information indicating the row index m may be included in the ConfiguredGrantConfig IE. Note that the information indicating the row index m may be included in an IE other than the ConfiguredGrantConfig IE. Note that the size (i.e., the number of bits or bit width) of the information (IE) indicating the row index m may be determined based on, for example, the number of entries in the third table. That is, the size of the information indicating the row index m may be determined based on the number of parameters (or parameter sets) in the third table (that is, the number of parameters included (or entered) in the third table). Also, the third table information may be set individually or commonly for one or more CG configurations (e.g., Type 1 CG configuration and / or Type 2 CG configuration).

[0151] The control unit 110 of the terminal device 10 sets the third table based on the third table information. Furthermore, the terminal device 10 may transmit a PUSCH (i.e., type 1 CG PUSCH transmission) based on the third table information. The third table information includes at least one of parameters (d1) to (d7). The control unit 110 sets the third table shown in FIG. 16. In the third table, one row index is associated with one or more transmission opportunities. For example, row index "1" is associated with a parameter set corresponding to one transmission opportunity included in one period. Furthermore, row index "10" is associated with three parameter sets corresponding to three transmission opportunities included in one period. Note that in the example of FIG. 16, parameter (d1) (i.e., k2) is set commonly to the three transmission opportunities.

[0152] Assume that the terminal device 10 receives an RRC message including information indicating row index m (=9). The control unit 110 refers to row index m+1 in the third table. The control unit 110 obtains three parameter sets corresponding to three transmission opportunities associated with row index "10" in the third table. The control unit 110 uses the three parameter sets to determine the respective resources for uplink transmission.

[0153] The control unit 110 may determine the size of the information about unused opportunities based on the number of valid (or available) parameters associated with row index "10." In this example, the number of parameters (d2) associated with row index "10" is 3. The control unit 110 may determine (or decide) that the number of transmission opportunities Nt is "3" based on the number of parameters (d2) associated with row index "10." The control unit 110 may determine the size of the information about unused opportunities based on the number of transmission opportunities Nt. Note that the control unit 110 may determine the size of the information about unused opportunities based on the number of other parameters (e.g., (d3) or (d4)) associated with row index "10." Furthermore, if the third table includes parameters (d5) and / or (d6) and / or (d7), the control unit 110 may determine the size of the information about unused opportunities based on the number of parameters (d5) and / or (d6) and / or (d7).

[0154] For example, the control unit 110 sets the size of the field for the information on unused opportunities included in the UCI to 3 bits. That is, the control unit 110 generates the information on unused opportunities with a size of 3 bits. That is, the control unit 110 may determine the size of the information on unused opportunities to be the same as the number of transmission opportunities Nt. Here, the control unit 110 may determine the size of the information on unused opportunities to be the same as the number of transmission opportunities Nt-1. As described above, the information on unused opportunities is transmitted during uplink transmission opportunities. Therefore, uplink transmission opportunities used to transmit the information on unused opportunities may be excluded from the size of the information on unused opportunities. For example, the control unit 110 may identify the number of transmission opportunities Nt and determine the number obtained by subtracting 1 from the number of transmission opportunities Nt (e.g., the number obtained by subtracting the number of uplink transmission opportunities used to transmit the information on unused opportunities) as the size of the information on unused opportunities. Also, as described above, the control unit 110 may determine the size of the information on unused opportunities based on the product of the number of transmission opportunities Nt-1 and the number of periods Np. The communication unit 120 transmits the UCI including the above fields to the base station device 20 (S1503).

[0155] The control unit 210 of the base station device 20 determines the size of the information related to unused opportunities based on the third table information and the information indicating the row index m. That is, the control unit 210 determines that the size of the field related to the information related to unused opportunities included in the UCI is 3 bits. In this way, before receiving UCI from the terminal device 10, the control unit 210 can recognize the size of the field related to the information related to unused opportunities included in the UCI.

[0156] The transmission of UCI will be specifically described below. The example of FIG. 17 includes a first period P1 and a second period P2. Three transmission opportunities are set for each of the first period P1 and the second period P2. The control unit 110 determines that the first and second transmission opportunities in the first period P1 will be used for uplink transmission. The control unit 110 generates a 3-bit sequence {110}. The first to third values ​​of the sequence correspond to the first to third transmission opportunities, respectively. That is, the bits of the information about unused opportunities may be arranged in ascending order to correspond to the ascending order of uplink transmission opportunities. A value of "0" may indicate that the transmission opportunity is not used for uplink transmission. A value of "1" may indicate that the transmission opportunity is used for uplink transmission. The communication unit 120 may transmit UCI including the above sequence to the base station device 20 at the first transmission opportunity in the first period P1. That is, information about unused opportunities in a certain period may indicate use and / or unused transmission opportunities in the certain period. For example, the terminal device 10 may indicate use and / or unused transmission opportunities in the certain period by transmitting information about unused opportunities in the certain period.

[0157] Here, the information regarding unused opportunities may indicate use and / or non-use of a transmission opportunity in a certain period after the information regarding the unused opportunities is transmitted. For example, the terminal device 10 may indicate use and / or non-use of a transmission opportunity in a period after the transmission of the information regarding the unused opportunities by transmitting information regarding the unused opportunities. For example, the terminal device 10 may indicate use and / or non-use of a transmission opportunity in a period following the certain period by transmitting information regarding unused opportunities in the certain period.

[0158] For example, when an instruction to transmit information about unused opportunities is set, the terminal device 10 may always transmit information about unused opportunities (e.g., bits of information about unused opportunities) at the first transmission opportunity in a period. For example, the terminal device 10 may determine the number of modulation symbols (also referred to as coded modulation symbols) for the bits of information about unused opportunities. Furthermore, the terminal device 10 may determine the number of modulation symbols for the bits of UL-SCH information (i.e., uplink data). For example, the terminal device 10 may transmit both information about unused opportunities and information about UL-SCH on the PUSCH at the first transmission opportunity by concatenating the modulation symbols for the bits of information about unused opportunities and the modulation symbols for the bits of UL-SCH information. Here, in concatenating the modulation symbols, the modulation symbols for the bits of information about unused opportunities may be concatenated first, and the modulation symbols for the bits of UL-SCH information may be concatenated later. This makes it possible to avoid truncating the modulation symbols for the bits of information about unused opportunities when mapping the modulation symbols for the concatenated information to scheduled PUSCH resources.

[0159] Furthermore, when the terminal device 10 does not have information on the UL-SCH (i.e., there is no information on the UL-SCH), the terminal device 10 may transmit information on unused opportunities without accompanying information on the UL-SCH. For example, when the terminal device 10 does not have information on the UL-SCH, the terminal device 10 may transmit information on unused opportunities without accompanying information on the UL-SCH, using the resources of the PUSCH at the first transmission opportunity. In other words, when the terminal device 10 has information on the UL-SCH (when there is no information on the UL-SCH), be ), the terminal device 10 may transmit both information about unused opportunities and information about UL-SCH, and may transmit information about unused opportunities without UL-SCH information if it does not have UL-SCH information. For example, if an instruction to transmit information about unused opportunities is set, a field for information about unused opportunities may always be reserved in the PUSCH resource at the first transmission opportunity. Furthermore, if it does not have UL-SCH information, the terminal device 10 may not need to transmit information about unused opportunities. For example, if it does not have UL-SCH information, the terminal device 10 may skip (or drop) the transmission of information about unused opportunities at the first transmission opportunity.

[0160] Furthermore, when the terminal device 10 has information on the UL-SCH, it may transmit information on unused opportunities. For example, the terminal device 10 may always transmit information on unused opportunities together with information on the UL-SCH. For example, when the terminal device 10 does not have information on the UL-SCH at the first transmission opportunity but has information on the UL-SCH at the second transmission opportunity, it may transmit both information on unused opportunities and information on the UL-SCH at the second transmission opportunity.

[0161] Furthermore, information about unused opportunities may be transmitted together with information about UL-SCHs whose redundancy version number corresponds to "0". For example, the terminal device 10 may transmit information about unused opportunities only when the redundancy version number corresponding to the UL-SCH information to be transmitted is "0". For example, if the terminal device 10 does not have UL-SCH information at the first transmission opportunity but has UL-SCH information at the second transmission opportunity, it may transmit UL-SCH information whose redundancy version number corresponds to "0" at the second transmission opportunity. For example, information about unused opportunities may be transmitted together with UL-SCH information whose redundancy version number corresponds to "0" and is transmitted at the second transmission opportunity.

[0162] Furthermore, the terminal device 10 may transmit information indicating that information regarding unused opportunities is to be transmitted (or that information regarding unused opportunities is to be included in (or mapped or multiplexed into) the PUSCH). The information indicating that information regarding unused opportunities is to be transmitted may include information indicating that information regarding unused opportunities is present in the PUSCH. The terminal device 10 may concatenate bits of the information indicating that information regarding unused opportunities is to be transmitted and bits of the information regarding unused opportunities, and determine the number of modulation symbols for the bits of the concatenated information. For example, in concatenating the information bits, the bits of the information indicating that information regarding unused opportunities is to be transmitted may be concatenated first, and the bits of the information regarding unused opportunities may be concatenated later. By first identifying the information indicating that information regarding unused opportunities is to be transmitted, the base station device 20 becomes able to identify that information regarding unused opportunities is included in PUSCH resources, and becomes able to decode information regarding subsequent unused opportunities. Furthermore, as described above, the terminal device 10 may transmit information indicating a redundancy version number (for example, information indicating the redundancy version number "0"). For example, the terminal device 10 may concatenate bits of the information indicating the redundancy version number and bits of the information regarding unused opportunities, and determine the number of modulation symbols for the bits of the concatenated information. For example, in concatenating information bits, the bit of information indicating that information indicating the redundancy version number is to be transmitted may be concatenated first, and the bit of information regarding unused opportunities may be concatenated after. By first identifying the information indicating the redundancy version number (for example, information indicating the redundancy version number "0"), the base station device 20 can identify that information regarding unused opportunities is included in the PUSCH resources, and can decode the information regarding the subsequent unused opportunities.

[0163] Here, a transmission opportunity being used for uplink transmission may be rephrased as meaning that it may be used for uplink transmission, may be used by the terminal device 10, and / or is a valid uplink resource. Also, a transmission opportunity being used for uplink transmission may be rephrased as meaning that it has a transmission opportunity (and / or a valid uplink resource) for uplink transmission (i.e., transmission of a PUSCH) and / or that an uplink grant is deemed to have occurred. A transmission opportunity not being used for uplink transmission may be rephrased as meaning that it may not be used for uplink transmission, may not be used by the terminal device 10, and / or is an invalid (i.e., not valid) uplink resource. Furthermore, a transmission opportunity not being used for uplink transmission may be rephrased as not having a transmission opportunity for uplink transmission (i.e., transmitting a PUSCH) (e.g., releasing, discarding, or ignoring uplink resources) and / or not considering that an uplink grant has occurred (i.e., considering that an uplink grant will not occur). In the above example, the value "0" corresponds to a value indicating that the transmission opportunity is not used for uplink transmission, and the value "1" corresponds to a value indicating that the transmission opportunity is used for uplink transmission, but this example is not limiting. The value "1" may correspond to a value indicating that the transmission opportunity is not used for uplink transmission, and the value "0" may correspond to a value indicating that the transmission opportunity is used for uplink transmission.

[0164] Furthermore, as described above, for example, the terminal device 10 may store, in the MAC layer (i.e., the MAC layer in the terminal device 10), an RRC message and / or DCI from the base station device 20 as a configured uplink grant, and may perform transmission of a PUSCH by regarding the uplink grant as occurring sequentially. Furthermore, in the physical layer (i.e., the physical layer in the terminal device 10), the terminal device 10 may include UCI including information about unused opportunities in the PUSCH (or may map or multiplex the UCI including information about unused opportunities to the PUSCH). That is, the MAC layer in the terminal device 10 may provide information about processing of the uplink grant to the physical layer in the terminal device 10. For example, the MAC layer may provide, to the physical layer, information indicating that it is determined that an uplink grant will occur (and / or indicating that it is not determined that an uplink grant will occur). For example, the MAC layer may provide the physical layer with information indicating that an uplink grant is considered to be generated (and / or that an uplink grant is not considered to be generated) based on the start and / or end of one CG period. The MAC layer in the terminal device 10 may also provide the physical layer with information regarding UL-SCH information. For example, the MAC layer may provide the physical layer with information indicating that UL-SCH information is present (or UL-SCH information is present or has been generated) and / or information indicating that UL-SCH information is not present (or UL-SCH information is not present or has not been generated). For example, the MAC layer may provide the physical layer with information regarding UL-SCH information based on the start and / or end of one CG period. That is, it may be determined in the MAC layer in the terminal device 10 that a transmission opportunity will be used (or will not be used) for uplink transmission. The physical layer in the terminal device 10 may also provide the MAC layer with information indicating that a transmission opportunity will be used (or will not be used) for uplink transmission. For example, the physical layer may provide information regarding unused opportunities to the MAC layer.For example, the physical layer may provide information indicating whether a transmission opportunity is used for uplink transmission (or not) to the MAC layer based on the start and / or end of one period of the CG. That is, whether a transmission opportunity is used for uplink transmission (or not) may be determined in the physical layer in the terminal device 10.

[0165] Similarly, the control unit 110 determines that all of the first through third transmission opportunities in the second period P2 are to be used for uplink transmission. The control unit 110 generates a 3-bit sequence {111}. The communication unit 120 may transmit UCI including the above sequence to the base station device 20 at the first transmission opportunity in the second period P2.

[0166] In Type 1, the third table information may be included in parameters related to CG. That is, the third table information may be included in the RRC message of step S1502. The third table information may be included in the ConfiguredGrantConfig IE.

[0167] -Type 2 For Type 2, the same operations as those described in the description of Type 1 may be applied. As shown in FIG. 18, communication unit 220 of base station apparatus 20 transmits an RRC message including parameters related to PUSCH to terminal apparatus 10 (S1801). The parameters related to PUSCH include third table information. The parameters related to PUSCH may be a PUSCH-Config IE. The third table information may be included in the PUSCH-Config IE. Note that the third table information may be included in an IE other than the PUSCH-Config IE. The third table information may be included in parameters related to CG. For example, the third table information may be included in a ConfiguredGrantConfig IE.

[0168] The control unit 110 of the terminal device 10 sets the third table based on the third table information. Furthermore, the terminal device 10 may transmit a PUSCH (i.e., type 2 CG PUSCH transmission) based on the third table information. The third table information includes at least one of parameters (d1) to (d7). The control unit 110 sets the third table shown in FIG. 16.

[0169] The communication unit 220 of the base station apparatus 20 transmits DCI to which a CRC scrambled by the CS-RNTI is added to the terminal apparatus 10 (S1802). This activates periodic transmission operations by the terminal apparatus 10 using the PUSCH. Furthermore, the DCI includes information indicating a row index m for referring to the third table. The information indicating the row index m may be included in the TDRA field in the DCI. The size of the TDRA field (i.e., the number of bits or bit width) may be determined based on, for example, the number of entries in the third table (i.e., the number of parameters (or parameter sets) included (or entered) in the third table information).

[0170] Assume that the information indicating row index m for referencing the third table indicates "9." The control unit 110 references row index m+1 in the third table. The control unit 110 obtains three parameter sets corresponding to three transmission opportunities associated with row index "10" in the third table. The control unit 110 uses the three parameter sets to determine the respective resources for uplink transmission.

[0171] Furthermore, similar to the case of Type 1 described above, the control unit 110 determines the size of the information regarding the unused opportunities based on the number of parameters associated with row index "10." Specifically, the control unit 110 determines (or decides) that the number of transmission opportunities Nt is "3" based on the number of parameters associated with row index "10." The control unit 110 determines the size of the information regarding the unused opportunities based on the number of transmission opportunities Nt. The control unit 110 may also determine the size of the information regarding the unused opportunities based on the number of transmission opportunities Nt-1. The control unit 110 may also determine the size of the information regarding the unused opportunities based on the product of the number of transmission opportunities Nt and the number of periods Np. The control unit 110 may also determine the size of the information regarding the unused opportunities based on the product of the number of transmission opportunities Nt-1 and the number of periods Np.

[0172] For example, the control unit 110 sets the size of the field of the information on unused opportunities included in the UCI to 3 bits. That is, the control unit 110 generates the information on unused opportunities with a size of 3 bits. The communication unit 120 transmits the UCI including the above field to the base station device 20 (S1803). Note that the communication unit 120 may transmit the UCI to the base station device 20 as described in FIG. 17.

[0173] The control unit 210 of the base station device 20 determines the size of the information related to unused opportunities based on the third table information and the information indicating the row index m. That is, the control unit 210 determines that the size of the field related to the information related to unused opportunities included in the UCI is 3 bits. In this way, before receiving UCI from the terminal device 10, the control unit 210 can recognize the size of the field related to the information related to unused opportunities included in the UCI.

[0174] According to the above configuration, the terminal device 10 can appropriately determine the size of the information related to unused opportunities based on the third table information and the instruction information (that is, information indicating the row index m).

[0175] Furthermore, the base station device 20 can appropriately recognize the size of the information related to the unused opportunities based on the third table information and the instruction information (i.e., information indicating the row index m). Therefore, the base station device 20 can appropriately receive UCI including information related to the unused opportunities. When the base station device 20 receives information related to the unused opportunities from the terminal device 10, it can allocate the unused opportunities to terminal devices other than the terminal device 10. According to this configuration, the base station device 20 can efficiently allocate radio resources to multiple terminal devices.

[0176] The configuration of the third table is not limited to the example of Fig. 16. As shown in Fig. 19, the parameter (d1) may be set individually for each of the three transmission opportunities. In this case, the control unit 110 may determine the size of the information regarding the unused opportunities based on the number of parameters (d1) associated with the row index.

[0177] The configuration of the information on unused opportunities is not limited to the example of FIG. 17. The information on unused opportunities may indicate the number of transmission opportunities to be used. The number of transmission opportunities to be used may indicate the number of consecutive transmission opportunities. For example, transmission opportunities after the transmission opportunity indicated based on the number of transmission opportunities may not be used for uplink transmission. In the example of FIG. 14, three transmission opportunities are set in one period, so the information on unused opportunities may be a two-bit sequence capable of expressing values ​​from 0 to 3. As described above, it is assumed that "9" is indicated by the information indicating the row index m for referencing the third table. In this case, the terminal device 10 may determine that the size of the information on unused opportunities is two bits based on the number of parameters (i.e., 3) associated with the row index "10" in the third table. Therefore, the terminal device 10 may generate a two-bit sequence as the information on unused opportunities. That is, the control unit 110 may determine the size of the field of the information on unused opportunities included in the UCI as ceil(log2(Nt)) using the number of transmission opportunities Nt. Here, the control unit 110 may determine the size of the information regarding unused opportunities as ceil(log2(Nt-1)). Alternatively, the control unit 110 may determine the size of the information regarding unused opportunities based on the multiplied value of ceil(log2(Nt)) and the number of periods Np. The control unit 110 may determine the size of the information regarding unused opportunities based on the multiplied value of ceil(log2(Nt-1)) and the number of periods Np.

[0178] As shown in FIG. 20 , the control unit 110 determines that the first and second transmission opportunities in the first period P1 are to be used for uplink transmission. Because the number of transmission opportunities to be used is "2," the control unit 110 may generate a two-bit sequence {10} corresponding to the value "2." The communication unit 120 may transmit UCI including the above sequence to the base station device 20 at the first transmission opportunity in the first period P1. That is, the communication unit 120 may indicate the use and / or unused status of transmission opportunities in a certain period by transmitting information regarding unused opportunities in the certain period. Here, the communication unit 120 may indicate the use and / or unused status of transmission opportunities in a period following the transmission of the information regarding the unused opportunities by transmitting information regarding the unused opportunities. For example, the communication unit 120 may transmit information regarding unused opportunities in a period to indicate the use and / or unusedness of transmission opportunities in a period following the period.

[0179] Similarly, the control unit 110 determines that all of the first through third transmission opportunities in the second period P2 are to be used for uplink transmission. Because the number of transmission opportunities to be used is "3," the control unit 110 may generate a 2-bit sequence {11} corresponding to the value "3." The communication unit 120 may transmit UCI including the above sequence to the base station device 20 at the first transmission opportunity in the second period P2.

[0180] The third table may be a table relating to resources for uplink transmission in the DG. For example, the third table may be the second table described above. The control unit 110 may use the table relating to resources for uplink transmission in the DG to determine resources for multiple transmission opportunities included in one period in the CG. The control unit 110 may use the second table to determine the size of information about unused opportunities in the same manner as described above.

[0181] The control unit 110 may switch between the first table and the third table according to the setting information. It can be said that the first table is a table used when one period includes one transmission opportunity, and the third table is a table used when one period includes multiple transmission opportunities. For example, when the terminal device 10 receives both the third table information and information indicating the row index m from the base station device 20, the control unit 110 may use the third table. That is, the control unit 110 uses the third table to determine the resources of the multiple transmission opportunities included in one period. Furthermore, the control unit 110 uses the third table to determine the size of the information regarding the unused opportunities.

[0182] On the other hand, the control unit 110 may use the first table when the terminal device 10 does not receive at least one of the third table information and the information indicating the row index m from the base station device 20. That is, the control unit 110 determines the uplink transmission resources using the first table (i.e., the parameters (or parameter set) included in the first table).

[0183] When the second table is used as the third table as described above, the control unit 110 may switch between the first table and the second table according to the setting information. When the terminal device 10 receives both the second table information and information indicating the row index m from the base station device 20, the control unit 110 may use the second table. That is, the control unit 110 uses the second table (i.e., the parameters (or parameter set) included in the second table) to determine the resources of multiple transmission opportunities included in one period. Furthermore, the control unit 110 uses the second table to determine the size of the information regarding unused opportunities.

[0184] On the other hand, the control unit 110 may use the first table when the terminal device 10 does not receive at least one of the second table information and information indicating the row index m from the base station device 20. That is, the control unit 110 determines the uplink transmission resources using the first table (i.e., the parameters (or parameter set) included in the first table).

[0185] (2) Second aspect The configuration information may include first information regarding the number of repetitions of uplink transmission (i.e., PUSCH transmission). For example, the first information may be included in a parameter related to CG included in an RRC message. For example, the first information may be included in a ConfiguredGrantConfig IE. The first information may be repK included in the ConfiguredGrantConfig IE. repK indicates the number of repetitions applied to a transmitted TB for PUSCH transmission by CG. repK may indicate the number Nt of multiple transmission opportunities included in one period. In this configuration, the control unit 110 determines the size of the information regarding unused opportunities based on the value of repK.

[0186] The configuration information may include second information regarding the number Nt of multiple transmission opportunities. For example, the second information may be included in parameters related to CG included in the RRC message. An IE corresponding to the second information may be newly defined in a ConfiguredGrantConfig IE. In this configuration, the control unit 110 determines the size of the information regarding unused opportunities based on the second information. As described above, the control unit 110 may determine the size of the information regarding unused opportunities by excluding uplink transmission opportunities used for transmitting the information regarding the unused opportunities. For example, the control unit 110 may determine the number Nt of transmission opportunities indicated based on the second information minus 1 as the size of the information regarding the unused opportunities. The control unit 110 may also determine the size of the information regarding the unused opportunities based on the second information and the number Np of periods (or information indicating the number Np of periods) (for example, based on the product of the number Nt of transmission opportunities and the number Np of periods). In addition, the control unit 110 may determine the size of the information regarding unused opportunities based on the number Nt-1 of transmission opportunities indicated based on the second information and the number Np of periods (for example, based on the multiplied value of the number Nt-1 of transmission opportunities and the number Np of periods).

[0187] According to the above configuration, the terminal device 10 can appropriately determine the size of the information related to unused opportunities based on the first information or the second information.

[0188] Similarly, the control unit 210 of the base station device 20 determines the size of the information related to unused opportunities based on the first information or the second information. In this way, the base station device 20 can recognize the size of the field of the information related to unused opportunities included in the UCI before receiving the UCI from the terminal device 10. Therefore, the base station device 20 can appropriately receive the UCI including the information related to unused opportunities.

[0189] (3) Third aspect The configuration information may include at least one of third information regarding the number of transmission opportunities for uplink transmission included in one slot, and fourth information regarding the number of slots included in a periodicity set in the CG.

[0190] The third information may be included in a parameter related to CG included in the RRC message. For example, the third information may be included in a ConfiguredGrantConfig IE. The third information may be cg-nrofPUSCH-InSlot included in the ConfiguredGrantConfig IE. cg-nrofPUSCH-InSlot indicates the number of consecutive PUSCH transmission opportunities in one slot.

[0191] The fourth information may be included in a parameter related to CG included in the RRC message. For example, the fourth information may be included in a ConfiguredGrantConfig IE. The fourth information may be cg-nrofSlots included in the ConfiguredGrantConfig IE. The cg-nrofSlots indicates the number of consecutive slots allocated within a period set in the CG.

[0192] Conventionally, when multiple transmission opportunities are configured in a CG of an unlicensed spectrum channel, the above cg-nrofPUSCH-InSlot and cg-nrofSlots are used. The above cg-nrofPUSCH-InSlot and cg-nrofSlots may also be applied when multiple transmission opportunities are configured in one period in a CG.

[0193] The control unit 110 determines the number Nt of transmission opportunities included in one period based on one or both of the third information and the fourth information. Then, the control unit 110 determines the size of the information about unused opportunities based on the number Nt of transmission opportunities. Alternatively, the control unit 110 may determine the size of the information about unused opportunities by subtracting 1 from the number Nt of transmission opportunities indicated based on one or both of the third information and the fourth information. Alternatively, the control unit 110 may determine the size of the information about unused opportunities based on one or both of the third information and the fourth information and the number Np of periods (or information indicating the number Np of periods) (e.g., based on the multiplication of the number Nt of transmission opportunities and the number Np of periods). Alternatively, the control unit 110 may determine the size of the information about unused opportunities based on the number Nt-1 of transmission opportunities indicated based on one or both of the third information and the fourth information and the number Np of periods (e.g., based on the multiplication of the number Nt-1 of transmission opportunities and the number Np of periods).

[0194] According to the above configuration, the terminal device 10 can appropriately determine the size of the information on unused opportunities based on one or both of the third information and the fourth information.

[0195] Similarly, the control unit 210 of the base station device 20 determines the size of the information related to unused opportunities based on one or both of the third information and the fourth information. In this way, the control unit 210 can recognize the size of the field of the information related to unused opportunities included in the UCI before receiving the UCI from the terminal device 10. Therefore, the base station device 20 can properly receive the UCI including the information related to unused opportunities.

[0196] (4) Fourth aspect The configuration information may include fifth information related to offsets for determining slot and / or symbol positions of transmission opportunities in a CG. That is, the fifth information may be used to determine slot and / or symbol positions of each of one or more transmission opportunities in a period. The fifth information may be used to determine positions of one or more uplink transmissions (i.e., PUSCH transmissions) in a period.

[0197] The fifth information may be included in a parameter related to CG included in the RRC message. For example, the fifth information may be included in a ConfiguredGrantConfig IE. The fifth information may be a timeDomainOffset included in the ConfiguredGrantConfig IE. The timeDomainOffset is a parameter used in a predetermined formula for determining the slot and / or symbol position of a transmission opportunity in the CG. Multiple timeDomainOffsets may be configured as the fifth information in the ConfiguredGrantConfig IE. When multiple timeDomainOffsets are configured, this may indicate that multiple transmission opportunities are configured in one period. For example, the base station device 20 may transmit an RRC message including a list of one or multiple timeDomainOffsets. For example, the multiple timeDomainOffsets included in the list may correspond to the ascending order of the multiple transmission opportunities. That is, the first timeDomainOffset in the list may correspond to the first transmission opportunity in a period, the second timeDomainOffset in the list may correspond to the second transmission opportunity in a period, and the third timeDomainOffset in the list may correspond to the third transmission opportunity in a period.

[0198] The control unit 110 determines (or determines) the number of transmission opportunities Nt based on the number of timeDomainOffsets. Then, the control unit 110 determines the size of the information about unused opportunities based on the number of transmission opportunities Nt. Alternatively, the control unit 110 may determine the number of transmission opportunities Nt indicated based on the number of timeDomainOffsets minus 1 as the size of the information about unused opportunities. Alternatively, the control unit 110 may determine the size of the information about unused opportunities based on the number of timeDomainOffsets and the number of periods Np (or information indicating the number of periods Np) (e.g., based on the multiplication value of the number of transmission opportunities Nt and the number of periods Np). Alternatively, the control unit 110 may determine the size of the information about unused opportunities based on the number of transmission opportunities Nt-1 indicated based on the number of timeDomainOffsets and the number of periods Np (e.g., based on the multiplication value of the number of transmission opportunities Nt-1 and the number of periods Np).

[0199] According to the above configuration, the terminal device 10 can appropriately determine the size of the information related to unused opportunities based on the fifth information.

[0200] Similarly, the control unit 210 of the base station device 20 determines the size of the information on unused opportunities based on the fifth information. In this way, the control unit 210 can recognize the size of the field of the information on unused opportunities included in the UCI before receiving the UCI from the terminal device 10. Therefore, the base station device 20 can properly receive the UCI including the information on unused opportunities.

[0201] In the first to fourth aspects, the UCI including information about unused opportunities may be a CG-UCI or another UCI, and the CG-UCI including information about unused opportunities may be used in an unlicensed spectrum channel or a licensed spectrum channel.

[0202] In an unlicensed spectrum channel, a CG-UCI including information about unused opportunities may include at least one of the above fields (c1) to (c5). That is, the CG-UCI may include a field for information about unused opportunities in addition to at least one of the fields (c1) to (c5). When a CG-UCI including information about unused opportunities is used in a licensed spectrum, the CG-UCI does not need to include at least one of the fields (c1) to (c5).

[0203] When CG-UCI is used to transmit information about unused opportunities, the multiplexing scheme described in Reference 2 may be used. For example, the multiplexing scheme described in Reference 2 may be used for multiplexing the CG-UCI containing information about unused opportunities with user data.
