Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is based on and claims the benefit of priority from Japanese Patent Application No. 2023-15570 filed on February 3, 2023, and Japanese Patent Application No. 2023-78777 filed on May 11, 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 38.321 V17.2.0 (2022-09) Summary of the Invention

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

[0007] In consideration of the above, CG that sets multiple transmission opportunities in one period has been studied. However, Non-Patent Document 2 does not describe a procedure for appropriately determining information associated with each of the multiple transmission opportunities. An example of information associated with each of the multiple transmission opportunities is a process identifier of a hybrid automatic repeat reQuest (HARQ). The above problem also occurs in ordinary terminal devices and base station devices that do not implement XR.

[0008] The present disclosure provides a technique capable of appropriately determining a HARQ process identifier associated with each of a plurality of transmission opportunities.

[0009] A terminal device according to the present disclosure includes: a receiving unit that receives, from a base station device, a Radio Resource Control (RRC) message including a CG configuration for configuring transmission of a Physical Uplink Shared Channel (PUSCH) based on a configured grant (CG); a control unit that, when the CG configuration includes information related to opportunities for transmitting a plurality of PUSCHs within one period, determines a Hybrid Automatic Repeat request process identifier (HARQ process ID) associated with each of the plurality of PUSCH transmissions based on the information and an offset value of the HARQ process ID; and a transmitting unit that executes transmission of each of the plurality of PUSCHs associated with the determined HARQ process ID within the one period.

[0010] Furthermore, the method of the 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 for configuring transmission of a Physical Uplink Shared Channel (PUSCH) based on the configured CG; if the CG configuration includes information related to multiple PUSCH transmission opportunities within one period, determining a Hybrid Automatic Repeat request process identifier (HARQ process ID) associated with each of the multiple PUSCH transmissions based on the information and an offset value of the HARQ process ID; and executing, within the one period, each of the multiple PUSCH transmissions associated with the determined HARQ process ID.

[0011] Furthermore, the base station device in the present disclosure includes: a transmitter that transmits, to a terminal device, a Radio Resource Control (RRC) message including a CG configuration for configuring transmission of a Physical Uplink Shared Channel (PUSCH) based on a configured grant (CG); a controller that, when the CG configuration includes information related to multiple PUSCH transmission opportunities within one period, determines a Hybrid Automatic Repeat request process identifier (HARQ process ID) associated with each of the multiple PUSCH transmissions based on the information and an offset value of the HARQ process ID; and a receiver that receives each of the multiple PUSCH transmissions associated with the determined HARQ process ID within the one period.

[0012] According to the above configuration, it is possible to appropriately determine the HARQ process identifier associated with each of the multiple 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]

[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.

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 can be applied in a communication system S. 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. Scheduling Request (SR) The SR is used by the terminal device 10 to request PUSCH radio resource allocation from the base station device 20. The SR may also be used to request UL-SCH resources for initial transmission. The base station device 20 allocates PUCCH resources for transmitting the SR to the terminal device 10. The base station device 20 transmits an RRC message including SR parameters to the terminal device 10. The SR parameters are included in a SchedulingRequestResourceConfig IE, which is an example of an RRC information element (IE).

[0081] The terminal device 10 transmits UCI including an SR to the base station device 20 using the configured PUCCH resource. The terminal device 10 may transmit UCI on demand. The terminal device 10 may transmit UCI at a configured periodicity. For example, the terminal device 10 may transmit an SR set to "0" (negative SR) and / or an SR set to "1" (positive SR). The base station device 20 allocates radio resources of a PUSCH to the terminal device 10 according to the SR.

[0082] 1.4.2. Configured Grant (CG) CG is a scheduling method for allocating radio resources for PUSCH without the procedure of transmitting SR. 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).

[0083] 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).

[0084] 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).

[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 at a set period without being triggered by DCI.

[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 (S902). For example, the terminal device 10 may store an RRC message including CG parameters as a configured uplink grant. Here, the RRC message including 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 (is repeated) 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 and parameters related to a second CG to the terminal device 10. The terminal device 10 may transmit a first PUSCH associated with the first CG and a second PUSCH associated with the second CG.

[0091] (2) Type 2 In Type 2, the terminal device 10 transmits a signal at a set period in response to activation by DCI scrambled with CS-RNTI.

[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 (S1003). For example, when DCI to which a CRC scrambled by the CS-RNTI is added (i.e., 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 (DCI format) used for scheduling the PUSCH is also referred to as an uplink grant. Furthermore, after an uplink grant is configured for CG type 2, the terminal device 10 may consider that uplink grants are sequentially generated (repeated) in SFNs and / or slot numbers that satisfy a predetermined formula. That is, the terminal device 10 may perform PUSCH transmission by considering that the stored uplink grants are sequentially generated in SFNs and / or slot numbers that satisfy a 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 multiple CGs may be configured in the terminal device 10 for one or more serving cells or one or more UL-BWPs. For example, the base station device 20 may transmit an RRC message including parameters related to a first CG and parameters related to a second CG to the terminal device 10. When the first CG is activated by DCI, the terminal device 10 may transmit a first PUSCH associated with the first CG. When the second CG is activated by DCI, the terminal device 10 may transmit a second PUSCH associated with the second CG.

[0096] 1.5. Hybrid Automatic Repeat Request (HARQ) HARQ is a mechanism for controlling error correction and retransmission requests. When a receiver detects an error in data received from a sender, it requests the sender to retransmit the data. The receiver then combines the previously received data with the retransmitted data to obtain the data.

[0097] HARQ is a SAW (Stop-And-Wait) protocol. When the receiving side correctly receives data, it sends an acknowledgement (Ack) to the transmitting side. When the transmitting side receives the Ack, it sends the next data. In this way, with HARQ, the transmitting side cannot send the next data until the receiving side has completed receiving the data.

[0098] The following describes a case where a transmission opportunity for a PUSCH is set by the CG.

[0099] The base station device 20 may transmit an RRC message including parameters related to the PUSCH to the terminal device 10. The parameters related to the PUSCH are included in a PUSCH-ServingCellConfig IE, which is an example of an RRC information element (IE).

[0100] The HARQ entity in the terminal device 10 can have one or more HARQ processes. For uplink transmission, the terminal device 10 supports up to 16 or 32 HARQ processes per cell. The number of HARQ processes is configured by nrofHARQ-ProcessesForPUSCH included in the parameters for PUSCH (i.e., PUSCH-ServingCellConfig IE). If nrofHARQ-ProcessesForPUSCH is not present in the PUSCH-ServingCellConfig IE, the number of HARQ processes is set to 16 by default.

[0101] For uplink transmission, each HARQ process supports one Transport Block (TB), i.e., one TB is transmitted in one transmission opportunity. Also, one HARQ process identifier is associated with (or assigned to) one HARQ process. Hereinafter, the HARQ process identifier will be referred to as "HARQ process ID."

[0102] When a transmission opportunity is set by CG, the terminal device 10 calculates the HARQ process ID using the following formula A. Similarly, the base station device 20 calculates the HARQ process ID using formula A.

number

[0103] The parameters in Equation A are as follows: periodicity: periodicity set for transmitting PUSCH -nrofHARQ-Processes: Number of HARQ processes -SFN: System Frame Number -numberOfSlotsPerFrame: Number of slots contained in one radio frame -numberOfSymbolsPerSlot: Number of symbols in one slot

[0104] The terminal device 10 associates the HARQ process ID calculated using Equation A with the HARQ process. The terminal device 10 may transmit a PUSCH to the base station device 20 at the set transmission opportunity.

[0105] When multiple CGs are configured, the terminal device 10 may calculate the HARQ process ID using the following mathematical formula B. Similarly, the base station device 20 may calculate the HARQ process ID using mathematical formula B.

number

[0106] Current_symbol in Equation B is calculated using the same formula as Equation A. harq-ProcID-Offset2 is an offset value used to set different HARQ process IDs for each CG configuration in uplink transmission. harq-ProcID-Offset2 is included in the CG-related parameters (i.e., ConfiguredGrantConfig IE).

[0107] 1.5. 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.

[0108] 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.

[0109] 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)

[0110] 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.

[0111] 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.

[0112] 1.6. CG Expansion Basic Configuration XR is expected to be operated under the various requirements mentioned above. Accordingly, for uplink transmission from a terminal device, the use of CG scheduling instead of DG scheduling is being considered. As shown in FIG. 11, conventionally, one transmission opportunity is set in a single CG period. The period corresponds to the periodicity, which is a CG parameter explained above. In the example of FIG. 11, the period = 2 × 14 symbols.

[0113] The configuration in Fig. 11 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. 12. In the example in Fig. 12, the period = 2 × 14 symbols. The number of transmission opportunities included in one period is Nt = 3. Furthermore, the interval In between adjacent transmission opportunities included in one period is 5 symbols.

[0114] On the other hand, Non-Patent Document 2 does not describe a procedure for appropriately determining information associated with each of a plurality of transmission opportunities. An example of information associated with each of a plurality of transmission opportunities is an HARQ process ID. This embodiment provides a procedure for determining an HARQ process ID associated with each of a plurality of transmission opportunities.

[0115] Specifically, the terminal device 10 determines a HARQ process ID associated with each of the multiple transmission opportunities using configuration information related to multiple transmission opportunities included in one period in the CG. Hereinafter, for simplicity, the "configuration information related to multiple transmission opportunities included in one period in the CG" will be simply referred to as "configuration information." The terminal device 10 performs uplink transmission (i.e., PUSCH transmission) corresponding to the HARQ process to the base station device 20. Note that at least one of the multiple transmission opportunities does not have to be used for uplink transmission.

[0116] 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.

[0117] The base station device 20 may transmit the configuration information to the terminal device 10. The terminal device 10 may use the configuration information received from the base station device 20 to determine the HARQ process ID associated with each of the multiple transmission opportunities.

[0118] The configuration information may be stored in advance in the terminal device 10. The terminal device 10 may acquire the configuration information from the terminal device 10 itself. The terminal device 10 may use the acquired configuration information to determine a HARQ process ID associated with each of a plurality of transmission opportunities.

[0119] Similarly, the base station device 20 uses the configuration information to determine an HARQ process ID associated with each of the multiple transmission opportunities. The base station device 20 receives uplink transmissions from the terminal device 10 corresponding to the HARQ processes.

[0120] The base station device 20 may use the configuration information transmitted to the terminal device 10 to determine the HARQ process ID associated with each of the multiple transmission opportunities.

[0121] The base station device 20 may receive configuration information from the terminal device 10. The base station device 20 may use the received configuration information to determine an HARQ process ID associated with each of the multiple transmission opportunities.

[0122] Hereinafter, first to fourth aspects of the process for determining the HARQ process ID will be described.

[0123] (1) First aspect The configuration information may include first information indicating a HARQ process ID for each of the multiple transmission opportunities.

[0124] In step S901 of FIG. 9, the base station device 20 may transmit an RRC message including the first information to the terminal device 10. Furthermore, in step S1001 of FIG. 10, the base station device 20 may transmit an RRC message including the first information to the terminal device 10. The first information may be set as a new element of the ConfiguredGrantConfig IE. The first information may be set in an IE other than the ConfiguredGrantConfig IE. The base station device 20 may transmit system information (SI, for example, SIB1 and / or an SIB other than SIB1) including the first information to the terminal device 10. In step S1002 of FIG. 10, the base station device 20 may transmit DCI including the first information to the terminal device 10.

[0125] The CG period, the number of transmission opportunities Nt, and the interval between transmission opportunities In in Fig. 13 are the same as those in the example of Fig. 12. The example of Fig. 13 includes a first period P1, a second period P2, and a third period P3.

[0126] The first information may be a sequence of HARQ process IDs. For example, the first information may be a sequence of {0, 1, 2}. In this case, the control unit 110 of the terminal device 10 may use the sequence to determine an HARQ process ID associated with each of a plurality of transmission opportunities.

[0127] The control unit 110 may assign the above sequence to multiple transmission opportunities in order. That is, the control unit 110 assigns HARQ process ID "0" to the first transmission opportunity in the first period P1. The control unit 110 assigns HARQ process ID "1" to the second transmission opportunity in the first period P1. The control unit 110 assigns HARQ process ID "2" to the third transmission opportunity in the first period P1. In this manner, the control unit 110 may associate multiple values ​​included in the above sequence with multiple transmission opportunities, respectively. The control unit 110 may also associate multiple values ​​included in the above sequence with multiple transmission opportunities, respectively, in a similar manner in the second period P2 and the third period P3.

[0128] The first information may include multiple sequences. For example, the first information may include two sequences, {0,1,2} and {3,4,5}. The control unit 110 may select a sequence to associate with multiple transmission opportunities for each period. For example, the control unit 110 may apply the sequence {0,1,2} to the first period P1. The control unit 110 assigns HARQ process ID "0" to the first transmission opportunity of the first period P1. The control unit 110 assigns HARQ process ID "1" to the second transmission opportunity of the first period P1. The control unit 110 assigns HARQ process ID "2" to the third transmission opportunity of the first period P1.

[0129] For example, the control unit 110 may apply a sequence of {3, 4, 5} to the second period P2. The control unit 110 assigns HARQ process ID "3" to the first transmission opportunity of the second period P2. The control unit 110 assigns HARQ process ID "4" to the second transmission opportunity of the second period P2. The control unit 110 assigns HARQ process ID "5" to the third transmission opportunity of the third period P3.

[0130] The first information may include one or more parameters for selecting a sequence from a plurality of sequences, and the control unit 110 may select a sequence to be applied to each period from the plurality of sequences in accordance with the parameters.

[0131] According to the above configuration, the terminal device 10 can use the first information to determine the HARQ process ID associated with each of the multiple transmission opportunities included in one period. Similarly, the base station device 20 can use the first information to determine the HARQ process ID associated with each of the multiple transmission opportunities included in one period.

[0132] (2) Second aspect Hereinafter, the above-described Equation A will be referred to as "first equation." The first equation is used when one period includes one transmission opportunity. In contrast, in this aspect, a second equation different from the first equation is used. The second equation is used when one period includes multiple transmission opportunities. The second equation is a equation that can individually calculate a HARQ process ID for each of multiple transmission opportunities.

[0133] The setting information may include second information indicating that a second formula is to be used.

[0134] The second information may be information that explicitly indicates the use of the second formula, or may be information that implicitly indicates the use of the second formula. Examples of explicit information and examples of implicit information will be described below.

[0135] - Explicit information The second information may be "information indicating whether or not to use the second formula." The second information may indicate "to use the second formula" or "not to use the second formula." The second information may be a flag indicating "to use the second formula" or "not to use the second formula." The second information may indicate "to use the second formula" or "not to use the second formula" depending on whether the second information is present. For example, if the second information is present, this may indicate that the second formula is used. If the second information is absent, this may indicate that the second formula is not used. Note that the above "not to use the second formula" may be interpreted as "to use a formula different from the second formula." For example, "not to use the second formula" may be interpreted as "to use the first formula."

[0136] -Implicit information The second information may be information related to multiple transmission opportunities included in one period. For example, the second information may include at least one of the following (a1) to (a3): (a1) The number of transmission opportunities in one period, Nt (a2) The interval between adjacent transmission opportunities in one period (a3) Offset value Ofs for HARQ process ID

[0137] The interval In between transmission opportunities may be referred to as an inner periodicity. For example, the interval In between transmission opportunities may be set in units of the number of slots, the number of symbols, or FPS, similar to the parameter periodicity. For example, the offset value Ofs is an offset value used when one period includes multiple transmission opportunities. The offset value Ofs may be an offset value of the HARQ process IDs between adjacent transmission opportunities. That is, if the offset value Ofs is "2", the HARQ process IDs of adjacent transmission opportunities may be set so that the difference between the HARQ process IDs of the adjacent transmission opportunities is 2.

[0138] When the terminal device 10 receives at least one of (a1) to (a3) ​​from the base station device 20, the terminal device 10 may determine that the base station device 20 has instructed the use of the second mathematical formula. When the terminal device 10 does not receive any of (a1) to (a3) ​​from the base station device 20, the terminal device 10 may determine that the base station device 20 has instructed the use of the second mathematical formula.

[0139] In step S901 of FIG. 9, the base station device 20 may transmit an RRC message including the second information to the terminal device 10. Furthermore, in step S1001 of FIG. 10, the base station device 20 may transmit an RRC message including the second information to the terminal device 10. The second information may be set as a new element of the ConfiguredGrantConfig IE. The second information may be set in an IE other than the ConfiguredGrantConfig IE. The base station device 20 may transmit system information (SI, for example, SIB1 and / or an SIB other than SIB1) including the second information to the terminal device 10. In step S1002 of FIG. 10, the base station device 20 may transmit DCI including the second information to the terminal device 10.

[0140] If the second information indicates that the second formula is to be used, the control unit 110 of the terminal device 10 uses the second formula to determine the HARQ process ID associated with each of the multiple transmission opportunities.

[0141] If the second information does not indicate that the second formula is not to be used, the control unit 110 may use the first formula. That is, the control unit 110 may switch between the first formula and the second formula according to the second information.

[0142] For example, the second formula may be the following formula C. Formula C is a formula commonly used for multiple transmission opportunities included in one period. CURRENT_symbol is the same as the first formula (i.e., formula A). nrofHARQ-Processes is the number of HARQ processes, which is 15 in this example. The CG period, the number of transmission opportunities Nt, and the interval In between transmission opportunities (i.e., inner periodicity) in FIG. 14 are the same as those in the example of FIG. 12. As shown in FIG. 14, control unit 110 uses formula C as the second formula to determine the HARQ process ID associated with each of the multiple transmission opportunities.

number

[0143] Note that the second formula is not limited to the above formula C. The second formula may include one or more terms related to multiple transmission opportunities included in one period. The one or more terms may be related to at least one of (a1) to (a3). When the second formula includes a term related to at least one of (a1) to (a3), the terminal device 10 can determine a HARQ process ID associated with each of the multiple transmission opportunities.

[0144] According to the above configuration, the terminal device 10 can determine the HARQ process ID associated with each of the multiple transmission opportunities included in one period by using the second information and the second formula. Similarly, the base station device 20 can determine the HARQ process ID associated with each of the multiple transmission opportunities included in one period by using the second information and the second formula.

[0145] (3) Third aspect In this embodiment, a third formula different from the second formula is used. The third formula is used when one period includes multiple transmission opportunities. The third formula includes multiple formulas that are used individually for each of the multiple transmission opportunities included in one period. In this respect, the third formula differs from the second formula.

[0146] The setting information may include third information indicating the use of a third mathematical formula.

[0147] The third information may be information that explicitly indicates the use of the third mathematical formula, or may be information that implicitly indicates the use of the third mathematical formula. Examples of explicit information and examples of implicit information will be described below.

[0148] - Explicit information The third information may be "information indicating whether or not to use a third mathematical formula." The third information may indicate "to use a third mathematical formula" or "to not use a third mathematical formula." The third information may be a flag indicating "to use a third mathematical formula" or "to not use a third mathematical formula." The third information may indicate "to use a third mathematical formula" or "to not use a third mathematical formula" depending on whether the third information is present or not. For example, if the third information is present, this may indicate that the third mathematical formula is used. If the third information is absent, this may indicate that the third mathematical formula is not used. Note that the above "to not use a third mathematical formula" may be interpreted as "to use a mathematical formula different from the third mathematical formula." For example, "to not use a third mathematical formula" may be interpreted as "to use the first mathematical formula."

[0149] -Implicit information The third information may be information about a plurality of transmission opportunities included in one period. The third information may be information set for each of the plurality of transmission opportunities. For example, the third information may include at least one of the following (b1) to (b4): (b1) Number of transmission opportunities in one period Nt (b2) The interval between adjacent transmission opportunities in one period (b3) The number of HARQ processes corresponding to each of the multiple opportunities, nrofHARQ-Processes_i (b4) Offset values ​​harq-ProcID-Offset_i for the HARQ process ID corresponding to each of the multiple opportunities

[0150] nrofHARQ-Processes_i includes a plurality of parameters corresponding to each of a plurality of opportunities. Specifically, nrofHARQ-Processes_i may be a sequence indicating the number of HARQ processes used in the ith set of transmission opportunities included in each period. Note that nrofHARQ-Processes_i can also be said to be the number of HARQ process IDs used in the ith set of transmission opportunities included in each period. That is, the ith entry of the sequence indicating the number of HARQ processes may correspond to the ith transmission opportunity included in each period. Note that 1≦i≦Nt.

[0151] harq-ProcID-Offset_i includes a plurality of parameters corresponding to each of a plurality of opportunities. Specifically, harq-ProcID-Offset_i may be a sequence indicating an offset value for the HARQ process ID of the i-th transmission opportunity. Note that harq-ProcID-Offset_i can also be said to be an offset value for the HARQ process ID used in the i-th set of transmission opportunities included in each period. In other words, the i-th entry of the sequence indicating a plurality of offset values ​​for the HARQ process may correspond to the i-th transmission opportunity included in each period.

[0152] When the terminal device 10 receives at least one of (b1) to (b4) from the base station device 20, the terminal device 10 may determine that the base station device 20 has instructed the use of the third mathematical formula. When the terminal device 10 does not receive any of (b1) to (b4) from the base station device 20, the terminal device 10 may determine that the base station device 20 has instructed the use of the third mathematical formula.

[0153] In step S901 of FIG. 9, the base station device 20 may transmit an RRC message including the third information to the terminal device 10. Furthermore, in step S1001 of FIG. 10, the base station device 20 may transmit an RRC message including the third information to the terminal device 10. The third information may be set as a new element of the ConfiguredGrantConfig IE. The third information may be set in an IE other than the ConfiguredGrantConfig IE. The base station device 20 may transmit system information (SI, for example, SIB1 and / or an SIB other than SIB1) including the third information to the terminal device 10. In step S1002 of FIG. 10, the base station device 20 may transmit DCI including the third information to the terminal device 10.

[0154] If the third information indicates that the third formula is to be used, the control unit 110 of the terminal device 10 uses the third formula to determine the HARQ process ID associated with each of the multiple transmission opportunities.

[0155] When the third information indicates that the third formula is not to be used, the control unit 110 may use the first formula. That is, the control unit 110 may switch between the first formula and the third formula according to the third information.

[0156] For example, the third formula may be the following formula D. The third formula includes a term related to (b3) and a term related to (b4). Note that CURRENT_symbol and periodicity are the same as those in the first formula (i.e., formula A).

number

[0157] The CG period, the number of transmission opportunities Nt, and the interval between transmission opportunities In in FIG. 15 are the same as those in the example of FIG. 12. Hereinafter, the first set of transmission opportunities in each period is referred to as the "first transmission opportunity set 1501." The first transmission opportunity set 1501 includes the first transmission opportunity in the first period P1, the first transmission opportunity in the second period P2, and the first transmission opportunity in the third period P3. The second set of transmission opportunities in each period is referred to as the "second transmission opportunity set 1502." The second transmission opportunity set 1502 includes the second transmission opportunity in the first period P1, the second transmission opportunity in the second period P2, and the second transmission opportunity in the third period P3. The third set of transmission opportunities in each period is referred to as the "third transmission opportunity set 1503." The third set of transmission opportunities 1503 includes the third transmission opportunity in the first period P1, the third transmission opportunity in the second period P2, and the third transmission opportunity in the third period P3.

[0158] In this example, (b3) (i.e., nrofHARQ-Processes_i) is a sequence of {2,2,2}. The first value (=2) in the sequence indicates the number of HARQ processes used in the first transmission opportunity set 1501. The second value (=2) in the sequence indicates the number of HARQ processes used in the second transmission opportunity set 1502. The third value (=2) in the sequence indicates the number of HARQ processes used in the third transmission opportunity set 1503.

[0159] In this example, (b4) (i.e., harq-ProcID-Offset_i) is a sequence of {0, 2, 4}. The first value (=0) of the sequence indicates an offset value for the HARQ process ID used for the first transmission opportunity set 1501. Because the value is "0", the HARQ process ID of the first transmission opportunity set 1501 is not offset. The second value (=2) of the sequence indicates an offset value for the HARQ process ID used for the second transmission opportunity set 1502. The HARQ process ID of the second transmission opportunity set 1502 is offset by "2" with respect to the HARQ process ID of the first transmission opportunity set 1501. The third value (=4) of the sequence indicates an offset value for the HARQ process ID used for the third transmission opportunity set 1503. The HARQ process IDs of the third transmission opportunity set 1503 are offset by "4" relative to the HARQ process IDs of the first transmission opportunity set 1501.

[0160] The control unit 110 applies the sequence of (b3) and the sequence of (b4) to the formula D to calculate the following three formulas D-1 to D-3.

number

[0161] Specifically, control unit 110 substitutes the first value of the sequence of (b3) and the first value of the sequence of (b4) into Equation D. This enables control unit 110 to obtain Equation D-1 for first transmission opportunity set 1501. As shown in FIG. 15 , control unit 110 uses Equation D-1 to determine HARQ process IDs associated with each of the multiple transmission opportunities included in first transmission opportunity set 1501.

[0162] Control unit 110 substitutes the second value of the sequence of (b3) and the second value of the sequence of (b4) into Equation D. This enables control unit 110 to obtain Equation D-2 for second transmission opportunity set 1502. As shown in FIG. 15 , control unit 110 determines an HARQ process ID associated with each of the multiple transmission opportunities included in second transmission opportunity set 1502 using Equation D-2.

[0163] Control unit 110 substitutes the third value of the sequence of (b3) and the third value of the sequence of (b4) into Equation D. This enables control unit 110 to obtain Equation D-3 for third transmission opportunity set 1503. As shown in FIG. 15 , control unit 110 determines an HARQ process ID associated with each of the multiple transmission opportunities included in third transmission opportunity set 1503 using Equation D-3.

[0164] Note that the third equation is not limited to the above equation D. The third equation may include one or more terms related to multiple transmission opportunities included in one period. The one or more terms may be related to at least one of (b1) to (b4). When the third equation includes a term related to at least one of (b1) to (b4), the terminal device 10 can determine a HARQ process ID associated with each of the multiple transmission opportunities.

[0165] According to the above configuration, the terminal device 10 can determine the HARQ process ID associated with each of the multiple transmission opportunities included in one period by using the third information and the third formula. Similarly, the base station device 20 can determine the HARQ process ID associated with each of the multiple transmission opportunities included in one period by using the third information and the third formula.

[0166] (4) Fourth aspect The terminal device 10 may determine the HARQ process ID associated with each of the multiple transmission opportunities included in one period such that the HARQ process ID increases or decreases by a predetermined value Y.

[0167] The configuration information may include fourth information for determining the HARQ process ID as described above, which includes at least one of the predetermined value Y and the value of the HARQ process ID of the first transmission opportunity of each period.

[0168] In step S901 of FIG. 9, the base station device 20 may transmit an RRC message including the fourth information to the terminal device 10. Furthermore, in step S1001 of FIG. 10, the base station device 20 may transmit an RRC message including the fourth information to the terminal device 10. The fourth information may be set as a new element of the ConfiguredGrantConfig IE. The fourth information may be set in an IE other than the ConfiguredGrantConfig IE. The base station device 20 may transmit system information (SI, for example, SIB1 and / or an SIB other than SIB1) including the fourth information to the terminal device 10. In step S1002 of FIG. 10, the base station device 20 may transmit DCI including the fourth information to the terminal device 10.

[0169] The fourth information may be stored in advance in the terminal device 10. In this configuration, the control unit 110 acquires the fourth information from the terminal device 10 itself. That is, the fourth information may be determined in advance in a specification. For example, the above-mentioned predetermined value Y may be a predetermined value. The control unit 110 may calculate the value of the HARQ process ID of the first transmission opportunity of each period. The control unit 110 may calculate the value of the HARQ process ID of the first transmission opportunity of each period using a first mathematical formula.

[0170] Using the fourth information, control unit 110 determines the HARQ process ID associated with each of the multiple transmission opportunities included in one period.

[0171] The CG period, the number of transmission opportunities Nt, and the interval between transmission opportunities In in FIG. 16 are the same as those in the example of FIG. 12. The communication unit 120 receives fourth information from the base station device 20. The fourth information includes information indicating that the increment value (corresponding to the above-mentioned predetermined value Y) is "1." The fourth information further includes information indicating that the HARQ process ID of the first transmission opportunity in the first period P1 is "0" and that the HARQ process ID of the first transmission opportunity in the second period P2 is "1." The control unit 110 uses the fourth information to determine the HARQ process ID associated with each of the multiple transmission opportunities.

[0172] The control unit 110 determines the HARQ process ID of each transmission opportunity in the first period P1 so that the HARQ process ID increases by one from "0". Therefore, as shown in Fig. 16, the HARQ process ID associated with the first transmission opportunity in the first period P1 is "0". The HARQ process ID associated with the second transmission opportunity in the first period P1 is "1". The HARQ process ID associated with the third transmission opportunity in the first period P1 is "2".

[0173] Control unit 110 determines the HARQ process ID of each transmission opportunity in second period P2 so that the HARQ process ID increases by one from "1". Therefore, as shown in Fig. 16, the HARQ process ID associated with the first transmission opportunity in second period P2 is "1". The HARQ process ID associated with the second transmission opportunity in second period P2 is "2". The HARQ process ID associated with the third transmission opportunity in second period P2 is "3".

[0174] In another example, the control unit 110 uses the configuration information to determine the value of the HARQ process ID for the first transmission opportunity of each period. The communication unit 120 may transmit the determined HARQ process ID value to the base station device 20 at the first transmission opportunity of each period. For example, the control unit 110 determines that the HARQ process ID associated with the first transmission opportunity of the first period P1 is "0." The control unit 110 transmits UCI including the HARQ process ID "0" to the base station device 20 at the first transmission opportunity of the first period P1. The control unit 110 determines that the HARQ process ID associated with the first transmission opportunity of the second period P2 is "1." The control unit 110 transmits UCI including the HARQ process ID "1" to the base station device 20 at the first transmission opportunity of the second period P2. The base station device 20 increments or decrements the HARQ process ID received at the first transmission opportunity of each period by a predetermined value Y to determine the HARQ process ID associated with each of the multiple transmission opportunities included in one period.

[0175] According to the above configuration, the terminal device 10 can use the fourth information to determine the HARQ process ID associated with each of the multiple transmission opportunities included in one period. Similarly, the base station device 20 can use the fourth information to determine the HARQ process ID associated with each of the multiple transmission opportunities included in one period.

[0176] Furthermore, the above first to fourth aspects also have the following effect. It is assumed that when multiple transmission opportunities are set in one period, the terminal device 10 calculates the HARQ process ID using the above-mentioned first mathematical formula. In this case, the terminal device 10 calculates one value collectively for multiple transmission opportunities included in one period. The terminal device 10 cannot determine an HARQ process ID individually for each of multiple transmission opportunities included in one period. In contrast, according to the above-mentioned first to fourth aspects, the terminal device 10 can determine an HARQ process ID individually for each of multiple transmission opportunities included in one period.

[0177] -Variation 1-1 In the above first to fourth aspects, the HARQ process IDs of the multiple transmission opportunities included in one period are different from each other, but this is not limiting. The HARQ process IDs of the multiple transmission opportunities included in one period may be the same.

[0178] On the other hand, if the interval In between transmission opportunities is small, the next HARQ process may start before one HARQ process ends. In such a situation, if the HARQ process IDs of two adjacent transmission opportunities are the same, the terminal device 10 and / or the base station device 20 may not be able to process the HARQ process appropriately. A configuration in which the HARQ process IDs of multiple transmission opportunities included in one period are different from each other can prevent such problems from occurring. Note that, to prevent the above problem, the HARQ process IDs of at least two adjacent transmission opportunities included in one period may be different from each other.

[0179] -Variation 1-2 For one or more serving cells or one or more UL-BWPs, multiple CGs may be configured in the terminal device 10. The above first to fourth aspects may be applied to a terminal device 10 in which multiple CGs are configured.

[0180] 2. Second embodiment Next, the configuration of the second embodiment will be described. Below, only the parts that are different from the first embodiment will be described, and the parts that are the same as the first embodiment will not be described. Therefore, as long as there is no mutual contradiction, the configuration of the first embodiment and its modified examples can be applied to the configuration described in this embodiment.

[0181] The terminal device 10 determines an HARQ process ID associated with each of a plurality of transmission opportunities included in one period. The terminal device 10 transmits the determined HARQ process ID to the base station device 20.

[0182] (1) First aspect The CG period, the number of transmission opportunities Nt, and the interval between transmission opportunities In in FIG. 17 are the same as those in the example of FIG.

[0183] The control unit 110 of the terminal device 10 determines a HARQ process ID associated with each of the multiple transmission opportunities included in the first period P1. Assume that the HARQ process ID for the first transmission opportunity is "0," the HARQ process ID for the second transmission opportunity is "1," and the HARQ process ID for the third transmission opportunity is "2." The communication unit 120 may transmit UCI including the HARQ process ID to the base station device 20 for each of the multiple transmission opportunities included in the first period P1. As shown in FIG. 17 , the communication unit 120 transmits UCI including the HARQ process ID "0" to the base station device 20 at the first transmission opportunity of the first period P1. The communication unit 120 transmits UCI including the HARQ process ID "1" to the base station device 20 at the second transmission opportunity of the first period P1. The communication unit 120 transmits UCI including the HARQ process ID "2" to the base station device 20 at the third transmission opportunity of the first period P1.

[0184] Similarly, control unit 110 determines an HARQ process ID associated with each of the multiple transmission opportunities included in second period P2. As shown in Fig. 17 , communication unit 120 transmits UCI including an HARQ process ID to base station device 20 for each of the multiple transmission opportunities included in second period P2.

[0185] (2) Second aspect The CG period, the number of transmission opportunities Nt, and the interval between transmission opportunities In in FIG. 18 are the same as those in the example of FIG.

[0186] The control unit 110 determines an HARQ process ID associated with each of the multiple transmission opportunities included in the first period P1. The HARQ process IDs of the multiple transmission opportunities included in the first period P1 are the same as those in the example of FIG. 17. The control unit 110 generates a first sequence {0, 1, 2} indicating the HARQ process IDs of the multiple transmission opportunities included in the first period P1. As shown in FIG. 18, the communication unit 120 transmits UCI including the first sequence to the base station device 20 at the first transmission opportunity of the first period P1.

[0187] The control unit 110 determines an HARQ process ID associated with each of the multiple transmission opportunities included in the second period P2. The HARQ process IDs of the multiple transmission opportunities included in the second period P2 are the same as those in the example of FIG. 17. The control unit 110 generates a second sequence {1, 2, 3} indicating the HARQ process IDs of the multiple transmission opportunities included in the second period P2. As shown in FIG. 18, the communication unit 120 transmits UCI including the second sequence to the base station device 20 at the first transmission opportunity of the second period P2.

[0188] The control unit 110 may determine the number of bits of the UCI based on the number of transmission opportunities Nt. That is, the control unit 110 may determine the bit width of a field included in the UCI and indicating an HARQ process ID associated with each of the multiple transmission opportunities based on the number of transmission opportunities Nt. For example, when the number of transmission opportunities Nt=3 as described above, the number of bits of the UCI may be 3 bits. The control unit 110 may determine the number of bits of the UCI based on the number of transmission opportunities that are actually used out of the number of transmission opportunities Nt. The number of actually used transmission opportunities corresponds to the number obtained by subtracting "unused transmission opportunities," which will be described later, from the number of transmission opportunities Nt. In another example, the number of bits of the UCI may be predetermined.

[0189] As described above, the terminal device 10 may receive information indicating to transmit UCI including a HARQ process ID from the base station device 20. Hereinafter, this information is referred to as "first transmission instruction information." The terminal device 10 may transmit UCI including a HARQ process ID in accordance with the first transmission instruction information.

[0190] The first transmission instruction information may be information that explicitly indicates that UCI including an HARQ process ID is to be transmitted, or may be information that implicitly indicates that UCI including an HARQ process ID is to be transmitted. Examples of explicit information and implicit information will be described below.

[0191] - Explicit information The first transmission instruction information may be "information indicating whether to transmit a UCI including a HARQ process ID." The first transmission instruction information may indicate "to transmit a UCI including a HARQ process ID" or "not to transmit a UCI including a HARQ process ID." The first transmission instruction information may be a flag indicating "to transmit a UCI including a HARQ process ID" or "not to transmit a UCI including a HARQ process ID." The first transmission instruction information may indicate "to transmit a UCI including a HARQ process ID" or "not to transmit a UCI including a HARQ process ID" depending on whether the first transmission instruction information is present. For example, if the first transmission instruction information is present, it may indicate to transmit a UCI including a HARQ process ID. If the first transmission instruction information is absent, it may indicate not to transmit a UCI including a HARQ process ID.

[0192] -Implicit information The first transmission instruction information may be information regarding a plurality of transmission opportunities included in one period. For example, the first transmission instruction information may include at least one of the following (c1) to (c2): (c1) Number of transmission opportunities in one period Nt (c2) The interval between adjacent transmission opportunities in one period

[0193] In step S901 of FIG. 9, the base station device 20 may transmit an RRC message including first transmission instruction information to the terminal device 10. Furthermore, in step S1001 of FIG. 10, the base station device 20 may transmit an RRC message including first transmission instruction information to the terminal device 10. The first transmission instruction information may be set as a new element of the ConfiguredGrantConfig IE. The first transmission instruction information may be set in an IE other than the ConfiguredGrantConfig IE. The base station device 20 may transmit system information (SI, for example, SIB1 and / or an SIB other than SIB1) including the first transmission instruction information to the terminal device 10. In step S1002 of FIG. 10, the base station device 20 may transmit DCI including the first transmission instruction information to the terminal device 10.

[0194] According to the above configuration, the terminal device 10 determines an HARQ process ID individually for each of a plurality of transmission opportunities included in one period. Furthermore, the terminal device 10 transmits UCI including the HARQ process ID to the base station device 20. This allows the terminal device 10 to notify the base station device 20 of the HARQ process ID associated with each of a plurality of transmission opportunities included in one period.

[0195] -Variation 2-1 In the above first and second aspects, the HARQ process IDs of the multiple transmission opportunities included in one period are different from each other, but this is not limiting. The HARQ process IDs of the multiple transmission opportunities included in one period may be the same.

[0196] -Variation 2-2 A plurality of CGs may be configured in the terminal device 10 for one or more serving cells or one or more UL-BWPs. The above first and second aspects may be applied to a terminal device 10 in which a plurality of CGs are configured. In such a configuration, the terminal device 10 may determine a HARQ process ID as follows. Assume that a first CG and a second CG are configured. The terminal device 10 may determine a HARQ process ID so that the HARQ process ID used in the first CG does not overlap with the HARQ process ID used in the second CG.

[0197] In another example, a DG may be configured in addition to a CG. In this configuration, the terminal device 10 may determine the HARQ process ID so that the HARQ process ID used in the CG does not overlap with the HARQ process ID used in the DG.

[0198] 3. Third embodiment Next, a configuration of the third embodiment will be described. The configuration described in this embodiment can be applied to the configurations of the first and second embodiments and their modified examples, provided that there is no mutual contradiction.

[0199] The terminal device 10 may not use at least one of the 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."

[0200] The terminal device 10 may dynamically indicate unused opportunities to the base station device 20. Hereinafter, such an indication will be referred to as a "dynamic indication of unused opportunities."

[0201] The base station device 20 may transmit information indicating whether the dynamic instruction of unused opportunities is valid to the terminal device 10. Hereinafter, this information is referred to as "second transmission instruction information." The terminal device 10 may transmit UCI including the dynamic instruction of unused opportunities to the base station device 20 in accordance with the second transmission instruction information.

[0202] The second transmission instruction information may be "information indicating whether or not dynamic instruction of unused opportunities is enabled." The second transmission instruction information may indicate "that dynamic instruction of unused opportunities is enabled" or "that dynamic instruction of unused opportunities is not enabled." The second transmission instruction information may be a flag indicating "that dynamic instruction of unused opportunities is enabled" or "that dynamic instruction of unused opportunities is not enabled." The second transmission instruction information may indicate "that dynamic instruction of unused opportunities is enabled" or "that dynamic instruction of unused opportunities is not enabled" depending on whether the second transmission instruction information is present. For example, if the second transmission instruction information is present, this may indicate that dynamic instruction of unused opportunities is enabled. If the second transmission instruction information is not present, this may indicate that dynamic instruction of unused opportunities is not enabled.

[0203] In step S901 of FIG. 9, the base station device 20 may transmit an RRC message including second transmission instruction information to the terminal device 10. Furthermore, in step S1001 of FIG. 10, the base station device 20 may transmit an RRC message including second transmission instruction information to the terminal device 10. The second transmission instruction information may be set as a new element of the ConfiguredGrantConfig IE. The second transmission instruction information may be set in an IE other than the ConfiguredGrantConfig IE. The base station device 20 may transmit system information (SI, for example, SIB1 and / or an SIB other than SIB1) including the second transmission instruction information to the terminal device 10. In step S1002 of FIG. 10, the base station device 20 may transmit DCI including the second transmission instruction information to the terminal device 10.

[0204] (1) First aspect The second transmission instruction information may indicate whether the dynamic instruction of unused opportunities is enabled for all transmission opportunities included in one period. In the example of Figure 19, the number of transmission opportunities Nt = 6. It is assumed that the second transmission instruction information indicates that the dynamic instruction of unused opportunities is enabled.

[0205] In this configuration, the terminal device 10 may transmit UCI to the base station device 20, the UCI including information indicating whether each transmission opportunity is to be used. Here, the information 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 referred to as a bit string. For example, the information may be represented as a bit string, with each bit of the bit string corresponding to each of multiple transmission opportunities and used as a dynamic indication of unused opportunities. The control unit 110 determines that the first to fourth transmission opportunities are to be used for uplink transmission. The control unit 110 determines that the fifth to sixth transmission opportunities are not to be used for uplink transmission. In this case, the control unit 110 generates a sequence {1,1,1,1,0,0}. The first to sixth values ​​of the sequence correspond to the first to sixth transmission opportunities, respectively. A value of "1" indicates that the transmission opportunity is to be used for uplink transmission. A value of "0" indicates that the transmission opportunity is not to be used for uplink transmission. The communication unit 120 transmits UCI including the above sequence to the base station device 20 at the first transmission opportunity. Note that the UCI may be CG-UCI or a UCI other than CG-UCI. Here, the value indicating that the transmission opportunity will be used for uplink transmission may be rephrased as a value indicating that the transmission opportunity may be used for uplink transmission, a value indicating that the transmission opportunity may be used by the terminal device 10, and / or a value indicating that the transmission opportunity is a valid uplink resource. The value indicating that the transmission opportunity will not be used for uplink transmission may be rephrased as a value indicating that the transmission opportunity may not be used for uplink transmission, a value indicating that the transmission opportunity may not be used by the terminal device 10, and / or a value indicating that the transmission opportunity is an invalid (i.e., invalid) uplink resource. In the above example, the value "0" corresponds to a value indicating that the transmission opportunity will not be used for uplink transmission, and the value "1" corresponds to a value indicating that the transmission opportunity will be used for uplink transmission, but this example is not limiting. A value of "1" may correspond to a value indicating that the transmission opportunity is not used for uplink transmission, and a value of "0" may correspond to a value indicating that the transmission opportunity is used for uplink transmission.

[0206] In another example, the control unit 110 may transmit UCI including a value indicating the number of transmission opportunities to be used to the base station device 20. In the example of Fig. 19, the value may be "4". The value "4" indicates that the first through fourth transmission opportunities of the six transmission opportunities are used for uplink transmission.

[0207] Assume that the second transmission instruction information indicates that the dynamic instruction of unused opportunities is not enabled. In this case, the control unit 110 may use all transmission opportunities included in one period for uplink transmission.

[0208] (2) Second aspect The second transmission indication information may indicate whether the dynamic indication of unused opportunities is enabled for each HARQ process ID. In the example of Figure 20, the number of transmission opportunities Nt = 6. Furthermore, the number of HARQ processes (i.e., nrofHARQ-Processes) is "2". Two values, "0" and "1", are used as the HARQ process ID.

[0209] The HARQ process ID of the first transmission opportunity, the HARQ process ID of the third transmission opportunity, and the HARQ process ID of the fifth transmission opportunity are all 0. Hereinafter, the set of transmission opportunities with an HARQ process ID of 0 will be referred to as the "first transmission opportunity set 2001."

[0210] The HARQ process ID of the second transmission opportunity, the HARQ process ID of the fourth transmission opportunity, and the HARQ process ID of the sixth transmission opportunity are all 1. Hereinafter, the set of transmission opportunities with an HARQ process ID of 1 will be referred to as the "second transmission opportunity set 2002."

[0211] The second transmission instruction information may indicate whether the dynamic indication of unused opportunities is enabled for each transmission opportunity set. For example, the second transmission instruction information may be information based on the number of HARQ processes used in the CG (i.e., nrofHARQ-Processes). The second transmission instruction information may be a sequence having a number of bits corresponding to the number of HARQ processes. In the example of FIG. 20, since the number of HARQ processes is "2", the second transmission instruction information is a two-bit sequence. For example, the second transmission instruction information is the sequence {1,0}. The first value of the above sequence corresponds to the first transmission opportunity set 2001. A value of "1" indicates that the dynamic indication of unused opportunities is enabled in the first transmission opportunity set 2001. The second value of the above sequence corresponds to the second transmission opportunity set 2002. A value of "0" indicates that the dynamic indication of unused opportunities is not enabled in the second transmission opportunity set 2002.

[0212] The control unit 110 determines whether each of the transmission opportunities included in the first transmission opportunity set 2001 will be used. The control unit 110 determines to use the first and third transmission opportunities for uplink transmission. The control unit 110 determines not to use the fifth transmission opportunity for uplink transmission. In this case, the control unit 110 generates a sequence {1,1,0}. The first value of the sequence corresponds to the first transmission opportunity. The second value of the sequence corresponds to the third transmission opportunity. The third value of the sequence corresponds to the fifth transmission opportunity. The value "1" indicates that the transmission opportunity will be used for uplink transmission. The value "0" indicates that the transmission opportunity will not be used for uplink transmission. The communication unit 120 transmits UCI including the above sequence to the base station device 20 at the earliest transmission opportunity (i.e., the first transmission opportunity) in the first transmission opportunity set 2001. Note that the UCI may be CG-UCI or a UCI other than CG-UCI. Here, a value indicating that a transmission opportunity will be used for uplink transmission may be rephrased as a value indicating that the transmission opportunity may be used for uplink transmission, a value indicating that the transmission opportunity may be used by the terminal device 10, and / or a value indicating that the transmission opportunity is a valid uplink resource. A value indicating that a transmission opportunity will not be used for uplink transmission may be rephrased as a value indicating that the transmission opportunity may not be used for uplink transmission, a value indicating that the transmission opportunity may not be used by the terminal device 10, and / or a value indicating that the transmission opportunity is an invalid (i.e., invalid) uplink resource. In the above example, the value "0" corresponds to a value indicating that the transmission opportunity will not be used for uplink transmission, and the value "1" corresponds to a value indicating that the transmission opportunity will be used for uplink transmission, but this example is not limiting. The value "1" may correspond to a value indicating that the transmission opportunity will not be used for uplink transmission, and the value "0" may correspond to a value indicating that the transmission opportunity will be used for uplink transmission.

[0213] In another example, the control unit 110 may transmit UCI including a value indicating the number of transmission opportunities to be used to the base station device 20. In the example of Fig. 20, the value may be "2". The value "2" indicates that the first and third transmission opportunities in the first transmission opportunity set 2001 are used for uplink transmission.

[0214] In this example, dynamic indication of unused opportunities is not enabled in the second set of transmission opportunities 2002. In this case, the controller 110 may use all transmission opportunities included in the second set of transmission opportunities 2002 for uplink transmission.

[0215] According to the above configuration, the terminal device 10 can dynamically indicate unused opportunities to the base station device 20. When the base station device 20 receives a dynamic indication of an unused opportunity from the terminal device 10, it can allocate the unused opportunity to a terminal device other than the terminal device 10. According to this configuration, the base station device 20 can efficiently allocate radio resources to a plurality of terminal devices.

[0216] -Variation 3-1 The control unit 110 may determine the size (i.e., the number of bits or the bit width) of the information corresponding to the dynamic instruction based on the setting information. For example, the control unit 110 may determine the number of bits of a field corresponding to the dynamic instruction included in the UCI based on the setting information.

[0217] For example, when the configuration information includes the first information, the size of the information corresponding to the dynamic instruction may be determined based on the number of HARQ process IDs indicated by the first information. For example, when the first information is a sequence of {0, 1, 2} as in the example of FIG. 13, the size of the information corresponding to the dynamic instruction may be 3 bits.

[0218] When the configuration information includes third information, the size of the information corresponding to the dynamic instruction may be determined based on at least one piece of information included in the third information. That is, the number of bits of the information corresponding to the dynamic instruction may be determined based on the number of parameters included in the at least one piece of information included in the third information. For example, the size of the information corresponding to the dynamic instruction may be determined based on nrofHARQ-Processes_i. That is, the number of bits of the information corresponding to the dynamic instruction may be determined based on the number of parameters included in nrofHARQ-Processes_i. For example, when the number of parameters included in nrofHARQ-Processes_i is three as in the example of FIG. 15 , the size of the information corresponding to the dynamic instruction may be three bits.

[0219] The size of the information corresponding to the dynamic instruction may be determined based on harq-ProcID-Offset_i. That is, the size of the information corresponding to the dynamic instruction may be determined based on the number of parameters included in harq-ProcID-Offset_i. When the number of parameters included in harq-ProcID-Offset_i is three as in the example of Fig. 15, the size of the information corresponding to the dynamic instruction may be three bits.

[0220] In the above second aspect, the size of the information corresponding to the dynamic instruction may be determined based on the number of transmission opportunities included in the first transmission opportunity set 2001. The size of the information corresponding to the dynamic instruction may be determined based on the number of transmission opportunities included in the second transmission opportunity set 2002.

[0221] 4. Fourth embodiment Next, the configuration of the fourth embodiment will be described. Two or more aspects or elements described in the first, second, and third embodiments can be combined as long as there is no mutual contradiction. In this embodiment, a combination of a part of the second aspect of the first embodiment (e.g., selection of a mathematical formula) and a part of the fourth aspect of the first embodiment (e.g., increment at a predetermined value Y) will be described.

[0222] When multiple transmission opportunities are set in one period in the CG by the configuration information, the control unit 110 uses multiple formulas to determine the HARQ process IDs associated with each of the multiple transmission opportunities included in one period.

[0223] The configuration information may include fifth information for determining an HARQ process ID. For example, the fifth information may include parameters related to the above-described formulas. The control unit 110 may determine an HARQ process ID associated with each of the transmission opportunities included in one period by applying the fifth information to the formulas.

[0224] The plurality of equations may include Eq1, which is applied to a first valid or configured opportunity among a plurality of transmission opportunities included in one period, and Eq2, which is applied to an opportunity (N (N>1)th transmission opportunity) other than the first opportunity among the plurality of transmission opportunities. Here, the first transmission opportunity may include a first uplink transmission. Also, the transmission opportunity other than the first transmission opportunity may include an uplink transmission other than the first uplink transmission.

[0225] The control unit 110 may select the formulas Eq1 and Eq2 using a predetermined parameter. For example, the predetermined parameter may be harq-ProcID-Offset2. As described above, harq-ProcID-Offset2 is a parameter used when multiple CGs are set. harq-ProcID-Offset2 may also be applied when multiple transmission opportunities are set in one period in a CG. Therefore, when multiple transmission opportunities are set in one period by the configuration information, the control unit 110 may select the formulas Eq1 and Eq2 based on whether harq-ProcID-Offset2 is included in the configuration information.

[0226] For example, when multiple transmission opportunities are set in one period using the configuration information and harq-ProcID-Offset2 is not included in the configuration information, the control unit 110 may select formulas Eq1 and Eq2 as follows: That is, when multiple transmission opportunities are set in one period using the configuration information, the control unit 110 may select formulas Eq1 and Eq2 as follows: Also, when harq-ProcID-Offset2 is not included in the configuration information, the control unit 110 may select formulas Eq1 and Eq2 as follows:

[0227] The control unit 110 may select the following formula E-1 as formula Eq1.

number

[0228] Equation E-1 is an equation in which X, offset1, and offset2 are added to Equation A. X may be 1. X may be the number of transmission opportunities Nt. offset1 may be zero. offset1 may be a value other than zero. offset2 may be zero. offset2 may be a value other than zero.

[0229] In addition, in formula E-1, at least one of X, offset1, and offset2 may be omitted. Furthermore, control unit 110 may select formula E-1a below as formula Eq1 instead of formula E-1.

number

[0230] The control unit 110 may select the following formula E-2 as formula Eq2.

number

[0231] In Equation E-2, Preceding HARQ Process ID is the HARQ process ID associated with the previous transmission opportunity in the period. That is, the HARQ process ID associated with the (i+1)th transmission opportunity included in each period may be determined based on the HARQ process ID associated with the i-th transmission opportunity. Y may be the same as the predetermined value Y described in the fourth aspect of the first embodiment. Therefore, Equation E-2 is an equation in which the HARQ process ID is incremented by the predetermined value Y, and the resulting value is modulo-operated by nrofHARQ-Processes (i.e., the number of HARQ processes).

[0232] In contrast to the above, when multiple transmission opportunities are set in one period using configuration information and harq-ProcID-Offset2 is included in the configuration information, control unit 110 may select formulas Eq1 and Eq2 as follows: That is, when multiple transmission opportunities are set in one period using configuration information, control unit 110 may select formulas Eq1 and Eq2 as follows: Also, when harq-ProcID-Offset2 is included in the configuration information, control unit 110 may select formulas Eq1 and Eq2 as follows:

[0233] The control unit 110 may select the following formula F-1 as formula Eq1.

number

[0234] Formula F-1 is a formula in which X, offset1, and offset2 are added to Formula B. The values ​​of X, offset1, and offset2 may be the same as those described above.

[0235] In addition, in formula F-1, at least one of X, offset1, and offset2 may be omitted. Furthermore, the control unit 110 may select the following formula F-1a as formula Eq1 instead of formula F-1.

number

[0236] In this case, the formula Eq2 may include one or more formulas. For example, the control unit 110 may select the following formula F-2 as the formula Eq2.

number

[0237] As described above, the Preceding HARQ Process ID is the HARQ process ID associated with the previous transmission opportunity in a period. That is, the HARQ process ID associated with the (i+1)th transmission opportunity included in each period may be determined based on the HARQ process ID associated with the i-th transmission opportunity. Y may be the same as the predetermined value Y described in the fourth aspect of the first embodiment.

[0238] Equation F-2 includes a modulo operation on a first value obtained by increasing (or incrementing) the HARQ process ID by a value Y, and an addition operation of a second value to the value obtained by the modulo operation. In this example, the second value is harq-ProcID-Offset2. The modulo operation also includes performing a modulo operation on the first value by a value obtained by adding the number of HARQ processes and the second value (i.e., nrofHARQ-Processes+harq-ProcID-Offset2). Hereinafter, the "value obtained by adding the number of HARQ processes and the second value" used in the modulo operation may be referred to as a "third value." Note that the above Equation F-2 is an example of Equation Eq2, and Eq2 may be any other equation as long as it includes the above modulo operation and the above addition operation.

[0239] In addition to formula F-2, the control unit 110 may select one of the following formulas (d1) to (d3) as formula Eq2. (d1) A formula that includes a modulo operation on a first value and does not include an addition operation on a second value. (d2) A formula that does not include a modulo operation on a first value and includes an addition operation on a second value. (d3) A formula that does not include a modulo operation on a first value and does not include an addition operation on a second value.

[0240] For example, the control unit 110 may select Formula F-3 as Formula Eq2. Formula F-3 is an example of Formula (d1).

number

[0241] When the control unit 110 uses a plurality of formulas as the formula Eq2, the control unit 110 may select one formula from the plurality of formulas based on a predetermined condition.

[0242] For example, when the first value is equal to or greater than the third value (i.e., nrofHARQ-Processes+harq-ProcID-Offset2), control unit 110 may determine the HARQ process ID using Equation F-2. When the first value is smaller than the third value, control unit 110 may determine the HARQ process ID using any of Equations (d1) to (d3). For example, when the first value is smaller than the third value, control unit 110 may determine the HARQ process ID using Equation F-3.

[0243] As described above, the configuration information may include fifth information for determining a HARQ process ID. The fifth information may include at least one parameter used in Eq1 and Eq2. For example, the fifth information may include at least one of X, offset1, and offset2. The fifth information may include, as X, the number of transmission opportunities Nt. The fifth information may include a predetermined value Y.

[0244] In step S901 of FIG. 9, the base station device 20 may transmit an RRC message including the fifth information to the terminal device 10. Furthermore, in step S1001 of FIG. 10, the base station device 20 may transmit an RRC message including the fifth information to the terminal device 10. The fifth information may be set as a new element of the ConfiguredGrantConfig IE. The fifth information may be set in an IE other than the ConfiguredGrantConfig IE. The base station device 20 may transmit system information (SI, for example, SIB1 and / or an SIB other than SIB1) including the fifth information to the terminal device 10. In step S1002 of FIG. 10, the base station device 20 may transmit DCI including the fifth information to the terminal device 10.

[0245] The base station device 20 may determine the HARQ process ID associated with each of the multiple transmission opportunities in the same manner as described above. The base station device 20 receives uplink transmissions from the terminal device 10 corresponding to the HARQ processes.

[0246] According to the above configuration, the terminal device 10 can appropriately determine the HARQ process ID associated with each of the multiple transmission opportunities included in one period.

[0247] For example, assume that the terminal device 10 determines the HARQ process ID using the following settings: Number of transmission opportunities Nt=5 nrofHARQ-Processes=8 harq-ProcID-Offset2=3 X=5 Y=1 offset1=0 offset2=0

[0248] As shown in FIG. 21, the transmission opportunity indicated by the symbol 2101 is the first transmission opportunity in a period, so the terminal device 10 determines the HARQ process ID for the transmission opportunity indicated by the symbol 2101 using formula F-1.

[0249] For the two transmission opportunities indicated by reference numeral 2102, the first value is smaller than the above-described third value (i.e., nrofHARQ-Processes+harq-ProcID-Offset2). Therefore, the terminal device 10 determines the HARQ process ID for the two transmission opportunities indicated by reference numeral 2102 using formula F-3.

[0250] In the transmission opportunity indicated by reference numeral 2103, the first value is equal to or greater than the third value. Therefore, the terminal device 10 determines the HARQ process ID for the transmission opportunity indicated by reference numeral 2103 using mathematical formula F-2. Accordingly, in the transmission opportunity indicated by reference numeral 2104, the first value is smaller than the third value. Therefore, the terminal device 10 determines the HARQ process ID for the transmission opportunity indicated by reference numeral 2104 using mathematical formula F-3.

[0251] In the above configuration, since harq-ProcID-Offset2=3 and nrofHARQ-Processes=8, it is considered that the intention is to use HARQ process IDs of 3 to 10. As shown in FIG. 21, the terminal device 10 can assign HARQ process IDs of 3 to 10 to multiple transmission opportunities. For example, if another mathematical formula (i.e., a mathematical formula different from Formula F-2) is used for the transmission opportunity indicated by reference numeral 2103, HARQ process IDs other than 3 to 10 may be assigned. For example, if multiple CGs are configured, an inconvenience may occur in which HARQ process IDs other than 3 to 10 cannot be used in other CGs. In the above configuration, the terminal device 10 uses Formula F-2 for the transmission opportunity indicated by reference numeral 2103. In Formula F-2, a second value (i.e., harq-ProcID-Offset2) is added to the value after the modulo operation. This addition operation can prevent HARQ process IDs other than 3 to 10 from being calculated. As described above, the terminal device 10 can allocate intended HARQ process IDs (ie, 3 to 10) to multiple transmission opportunities.
