[0002] This application claims the benefit of priority based on Japanese patent application No. 2023-23442 filed on February 17, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to a terminal device, a method for a terminal device, and a base station device. Background Art

[0004] In recent years, research and development of technologies related to extended reality (eXtended Reality, XR) has been advancing. XR is a concept that includes multimedia integrated technologies such as virtual reality (VR), augmented reality (AR), mixed reality (MR), and substitute reality (SR). In XR, three-dimensional time-series image data of real space and / or virtual space, multi-channel (stereo, 5.1ch, etc.) sound data, other data prompted to the user, control data, etc. are sent and received in parallel. In order to maintain and improve the quality of user experience, XR requires low latency and high reliability.

[0005] Non-Patent Document 1 discusses implementation of XR in 5G NR (Fifth Generation New Radio), a wireless specification defined by the Third Generation Partnership Project (3GPP (registered trademark)).

[0009] Non-Patent Document 2: 3GPP TS 38.214 V17.0.0 (2021-12) Summary of the Invention

[0010] XR is envisioned to be used under various requirements, including low latency. For XR traffic, the use of scheduling based on configured grants (CGs) rather than dynamic grants (DGs) for uplink transmissions from terminal devices is being explored. Conventionally, a single transmission opportunity is allocated within a single CG period. However, this configuration may not meet XR requirements.

[0011] Taking the above situation into consideration, a CG in which multiple transmission opportunities are configured in one time period is discussed. Furthermore, the processing of information related to unused occasions among multiple transmission opportunities sent by the terminal device to the base station device is also discussed. The inventors have discovered the following problem: in such a configuration, the terminal device and / or the base station device is required to appropriately determine the process of the size (i.e., the number of bits or bit width) of the above information. However, such a process is not recorded in non-patent document 2. In addition, the above problem will also occur in ordinary terminal devices and base station devices other than those that implement XR.

[0012] The present disclosure provides a technology capable of appropriately determining the size of information associated with unused opportunities among a plurality of transmission opportunities.

[0013] A terminal device in the present disclosure includes a receiving unit, a control unit, and a transmitting unit. The receiving unit receives a radio resource control (RRC) message including a configured grant (CG) configuration from a base station device, wherein the CG configuration includes information for configuring the timing of multiple physical uplink shared channel (PUSCH) transmissions based on the configured uplink grant and information for configuring the number of bits of uplink control information (UCI) including information related to unused transmission occasions. The control unit determines the number of bits of a UCI bitmap based on the information for configuring the number of bits of the UCI. The transmitting unit performs each of the multiple PUSCH transmissions based on the information for configuring the timing of the multiple PUSCH transmissions. The control unit multiplexes the bitmap of the UCI having the determined number of bits for each of the multiple PUSCH transmissions.

[0014] Furthermore, the method of the terminal device in the present disclosure includes: receiving a radio resource control (RRC) message including a configured grant (CG) configuration from a base station device, wherein the aforementioned CG configuration includes information for configuring the timing of multiple physical uplink shared channels (PUSCH) transmissions based on the configured uplink grant and information for configuring the number of bits of uplink control information (UCI) including information related to unused transmission occasions; determining the number of bits of the aforementioned UCI bitmap based on the aforementioned information for configuring the number of bits of the aforementioned UCI; and performing each of the aforementioned multiple PUSCH transmissions based on the aforementioned information for configuring the timing of the aforementioned multiple PUSCH transmissions. The aforementioned method also includes: multiplexing the aforementioned bitmap of the aforementioned UCI having the determined aforementioned number of bits for each of the aforementioned multiple PUSCH transmissions.

[0015] Furthermore, the base station device in the present disclosure includes a transmitting unit and a receiving unit. The transmitting unit transmits a radio resource control (RRC) message including a configured grant (CG) configuration to a terminal device, wherein the CG configuration includes information for configuring the timing of multiple physical uplink shared channel (PUSCH) transmissions based on the configured uplink grant and information for configuring the number of bits of uplink control information (UCI) including information related to unused transmission occasions. The receiving unit receives the multiple PUSCH transmissions. A bitmap of the UCI is multiplexed for each of the multiple PUSCH transmissions, and the UCI bitmap has a number of bits determined based on the information for configuring the number of bits of the UCI.

[0016] According to the above configuration, the size of information associated with unused opportunities among a plurality of transmission opportunities can be appropriately determined. In addition, the above configuration can also achieve other effects instead of or in addition to this effect. BRIEF DESCRIPTION OF THE DRAWINGS

The following embodiments can be modified or changed as appropriate according to the configuration of the device to which the present disclosure is applied and various conditions. All combinations of elements included in the following embodiments are not necessarily necessary to implement the present disclosure, and a part of the elements can be omitted as appropriate. Therefore, the scope of the present disclosure is not limited by the configurations described in the following embodiments. As long as there is no contradiction, a configuration combining multiple configurations described in the following embodiments can also be adopted.

[0040] 1. First Implementation

[0041] 1.1. Communication System

[0042] like Figure 1 As shown, the communication system S1 of the first embodiment includes one or more terminal apparatuses 10, one or more base station apparatuses 20, and a core network 30. The communication system S1 is configured in accordance with predetermined technical specifications (TS). For example, the communication system S1 may comply with the technical specifications specified by 3GPP (e.g., 5G, enhanced 5G evolution, 6G, etc.).

[0043] In communication system S1, a user plane (User Plane) for transmitting and receiving user data and a control plane (Control Plane) for transmitting and receiving control data are separately configured. In other words, communication system S1 supports C / U separation. The user plane is abbreviated as U-plane, and the control plane is abbreviated as C-plane.

[0044] The terminal device 10 is a device that wirelessly communicates with the base station device 20, and may be, for example, a user equipment (UE) that operates in accordance with the 3GPP 5G NR specification. Alternatively, the terminal device 10 may be a device that complies with other older or newer 3GPP specifications.

[0045] The terminal device 10 may be, for example, a mobile phone terminal such as a smartphone, a tablet terminal, a notebook PC, a communication module, a communication card, or an IoT device such as a surveillance camera or a robot. The terminal device 10 may be a vehicle (e.g., a car, a train, etc.) or a device installed therein. The terminal device 10 may be a portable body other than a vehicle (e.g., a ship, an airplane, etc.) or a device installed therein. The terminal device 10 may be a sensor or a device installed therein. In addition, the terminal device 10 may also be referred to as a terminal, a mobile station, a mobile terminal, a mobile device, a mobile unit, a subscriber station, a subscriber terminal, a subscriber device, a subscriber unit, a wireless station, a wireless terminal, a wireless device, a wireless unit, a remote station, a remote terminal, a remote device, a remote unit, or other names. The terminal device 10 may be one or more devices adapted for enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low Latency Communications (URLLC), and Massive Machine Type Communications (mMTC).

[0046] The base station device 20 manages at least one cell. A cell is 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" sometimes refers to a wireless communication resource and sometimes refers to a communication object of the terminal device 10. The base station device 20 wirelessly communicates with the terminal device 10 residing in this cell on the U-plane and C-plane. In other words, the base station device 20 terminates the U-plane protocol and the C-plane protocol for the terminal device 10.

[0047] Base station device 20 communicates with core network 30 on the U-plane and C-plane. More specifically, core network 30 includes multiple logical nodes, including an access and mobility management function (AMF) and a user plane function (UPF). Base station device 20 is connected to the AMF on the C-plane and to the UPF on the U-plane.

[0048] Base station device 20 may be, for example, a gNB that provides the U-plane and C-plane according to 3GPP's 5G NR specifications to terminal device 10 and is connected to 3GPP's 5G Core Network (5G Core Network). Alternatively, base station device 20 may be a device that complies with other older or newer 3GPP specifications.

[0049] The base station device 20 may also be composed of multiple unit devices. For example, the base station device 20 may also be composed of a central unit (CU), a distributed unit (DU), and a radio unit (RU).

[0050] Multiple base station devices 20 are interconnected to form a radio access network (RAN). The radio access network formed by base station devices 20 functioning as gNBs can be referred to as NG-RAN. Base station devices 20 functioning as gNBs can be referred to as NG-RAN nodes.

[0051] Multiple base station devices 20 are interconnected via predetermined interfaces (e.g., Xn interfaces). More specifically, for example, multiple base station devices 20 are interconnected via Xn-U interfaces on the U-plane and via Xn-C interfaces on the C-plane. Alternatively, multiple base station devices 20 may be interconnected via other interfaces with different functions or names.

[0052] Each base station device 20 is connected to the core network 30 via a predetermined interface (e.g., 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 on the U-plane, and is connected to the AMF of the core network 30 via an NG-C interface on the C-plane. Alternatively, each base station device 20 may be connected to the core network 30 via other interfaces with different functions or names.

[0053] Reference Figure 2 , the wireless protocol architecture between the terminal device 10 and the base station device 20 is described. Figure 3, the wireless protocol architecture between the terminal device 10 and the base station device 20 and between the terminal device 10 and the core network 30 is explained.

[0054] like Figure 2 As shown, the U-plane protocol stack includes, from the bottom, the physical (PHY) layer, the media access control (MAC) layer, the radio link control (RLC) layer, the packet data convergence protocol (PDCP) layer, and the service data adaptation protocol (SDAP) layer. These layers terminate at base station 20 on the network side.

[0055] like Figure 3 As shown, the C-plane protocol stack includes, from the bottom layer on up, the physical (PHY) layer, the media access control (MAC) layer, the radio link control (RLC) layer, the packet data convergence protocol (PDCP) layer, the radio resource control (RRC) layer, and the non-access stratum (NAS). With the exception of the non-access stratum, these layers terminate at the base station device 20 on the network side. The non-access stratum terminates on the network side through the AMF of the core network 30.

[0056] like Figure 4 As shown, the terminal device 10 has a processor 101, a memory 102, an input / output interface 103, a wireless interface 104, and an antenna 105 as hardware elements.

[0058] The memory 102 is composed of at least one storage medium such as RAM (Random Access Memory) or eMMC (embedded MultiMedia Card). The memory 102 is an element that temporarily or permanently stores programs and data used to execute various processes in the terminal device 10. The above-mentioned program includes one or more commands for the actions of the terminal device 10. The processor 101 executes the program stored in the memory 102 by expanding it on the memory 102 and / or the system memory (not shown), thereby realizing the functions of the terminal device 10.

[0059] The input / output interface 103 is an interface that receives operations on the terminal device 10 and supplies them to the processor 101, and also presents various information to the user. The input / output interface 103 is, for example, a touch panel.

[0060] The wireless interface 104 is a circuit that performs various signal processing for realizing wireless communication, and includes a baseband processor and an RF circuit. The wireless interface 104 transmits and receives wireless signals with the base station device 20 via the antenna 105 .

[0061] like Figure 5 As shown, the terminal device 10 includes a control unit 110 and a communication unit 120 as functional blocks. The communication unit 120 includes at least one transmission unit 121 and at least one reception unit 122.

[0062] The control unit 110 may also include at least one processor 101 and at least one memory 102. In other words, the control unit 110 may also be implemented by the processor 101 and the memory 102. The control unit 110 performs various control processes in the terminal device 10. For example, the control unit 110 controls wireless communication with the base station device 20 via the communication unit 120. In other words, the control unit 110 transmits and receives data, information, and messages via the communication unit 120.

[0063] Communication unit 120 includes wireless interface 104 and antenna 105. In other words, communication unit 120 is implemented by wireless interface 104 and antenna 105. Communication unit 120 wirelessly communicates with base station device 20 by transmitting and receiving wireless signals with base station device 20. Communication unit 120 may include two or more wireless interfaces 104 and two or more antennas 105.

[0064] The control unit 110 operates to execute various processes of the terminal device 10 according to this embodiment.

[0065] like Figure 6As shown, the base station device 20 has a processor 201, a memory 202, a network interface 203, a wireless interface 204, and an antenna 205 as hardware elements. The above elements provided in the base station device 20 are connected to each other via an internal bus. In addition, the base station device 20 may also have Figure 6 Hardware elements other than those shown.

[0066] The processor 201 is a computing element that implements various functions of the base station device 20. The processor 201 may be a CPU, or may also include other processors such as a GPU.

[0067] Memory 202 is composed of at least one storage medium, such as ROM (Read Only Memory), RAM, HDD (Hard Disk Drive), or SSD (Solid State Drive). Memory 202 temporarily or permanently stores programs and data used to execute various processes in base station device 20. These programs include one or more commands for the operation of base station device 20. Processor 201 executes the programs stored in memory 202 by expanding them into memory 202 and / or system memory (not shown), thereby implementing the functions of base station device 20.

[0068] The network interface 203 is an interface for transmitting and receiving signals with other base station devices 20 and the core network 30 .

[0069] The wireless interface 204 is a circuit that performs various signal processing for wireless communication, and includes a baseband processor and an RF circuit. The wireless interface 204 transmits and receives wireless signals with the terminal device 10 via the antenna 205 .

[0070] like Figure 7 As shown, the base station device 20 includes a control unit 210, a communication unit 220, and a network communication unit 230 as functional blocks. The communication unit 220 includes at least one transmission unit 221 and at least one reception unit 222.

[0074] The control unit 210 operates to execute various processes of the base station device 20 according to this embodiment.

[0075] 1.2. Wireless Resources

[0076] The terminal device 10 and the base station device 20 perform wireless communication with each other using radio resources in the frequency domain and the time domain.

[0077] 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 that applies CP-OFDM after performing transform precoding of discrete Fourier transform (DFT) spreading.

[0078] The cyclic prefix is ​​a redundant signal that functions as a guard period (GP) to prevent inter-symbol interference (ISI) and inter-carrier interference (ICI). It 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.

[0079] OFDM uses multiple mutually orthogonal subcarriers as frequency-domain radio resources. These subcarriers are arranged in the frequency domain with a predetermined subcarrier spacing (SCS) Δf. In communication system S1, multiple subcarrier spacings Δf can be used. Subcarrier spacing Δf is represented, for example, by the following equation.

[0080] Δf=2 μ 15[kHz]

[0081] Here, μ is an integer greater than or equal to 0 and can take at least one of the following values: 0, 1, 2, 3, 4, 5, or 6. Therefore, the subcarrier spacing Δf [kHz] can take at least one of the following values: 15, 30, 60, 120, 240, 480, or 960. Furthermore, μ can also take a value of 7 or greater.

[0082] In the OFDM time domain, using Figure 8 The hierarchical radio frame configuration shown in the figure. One radio frame consists of 10 subframes. Subframes are assigned subframe numbers that increment by 1 from 0 to 9. One radio frame is divided into two half-frames. The duration of a radio frame is 10 ms, the duration of a half-frame is 5 ms, and the duration of a subframe is 1 ms. These durations are independent of the subcarrier spacing Δf.

[0083] One subframe includes one or more time slots (s). The number of time slots Ns included in one subframe depends on the value of μ and, in turn, on the subcarrier spacing Δf. The number of time slots Ns is expressed, for example, by the following equation.

[0084] Ns=2 μ

[0085] One slot includes multiple symbols. The number of symbols in one slot depends on the type of cyclic prefix. For example, when a normal cyclic prefix is ​​used, one slot includes 14 symbols. For example, when an extended cyclic prefix is ​​used, one slot includes 12 symbols.

[0086] As described above, the number of slots and the number of symbols included in each of a radio frame, a half-frame, and a subframe having a fixed time length are variable. Therefore, the time length of a slot and the time length of a symbol are also variable.

[0087] A resource element (RE) is a radio resource unit in the time-frequency domain consisting of one subcarrier and one symbol, while a resource block (RB) is a radio resource unit in the time-frequency domain consisting of 12 subcarriers and multiple symbols.

[0088] Radio frames are assigned a System Frame Number (SFN), which increments by 1 from 0 to 1023. SFN "0" corresponds to the initial SFN value, and SFN "1023" corresponds to the maximum SFN value. Therefore, the radio frame following a radio frame assigned SFN 1023 is assigned SFN 0. The radio frame duration is 10 ms, so the duration of one system frame number cycle is 10240 ms (= 10.24 seconds).

[0089] Here, the base station device 20 may also configure one or more serving cells for the terminal device 10. The serving cells may also correspond to component carriers in the downlink and / or component carriers in the uplink. The technology of configuring one or more serving cells to perform wireless communication between the base station device 20 and the terminal device 10 can also be called carrier aggregation.

[0090] In addition, the base station device 20 may also configure one or more bandwidth parts (Bandwidth Part, BWP) for the terminal device 10 for each of one or more service cells. For example, a downlink bandwidth part (DownLink Bandwidth Part, DL-BWP) may also be configured in the downlink of one service cell. In addition, an uplink bandwidth part (UpLink Bandwidth Part, UL-BWP) may also be configured in the uplink of one service cell. Here, DL-BWP may also include an initial DL-BWP (InitialDL-BWP) and / or a dedicated DL-BWP (Dedicated DL-BWP). In addition, UL-BWP may also include an initial UL-BWP (Initial UL-BWP) and / or a dedicated UL-BWP (Dedicated UL-BWP). Hereinafter, BWP may also include DL-BWP and / or UL-BWP.

[0091] 1.3. Channel and Control Information

[0092] The terminal device 10 and the base station device 20 transmit and receive user data and control information to and from each other. The following describes examples of transmission and reception of control information in downlink and uplink.

[0093] Terminal device 10 and base station device 20 use multiple hierarchical channels to transmit and receive user data and control information. Physical channels are used for physical layer communication between terminal device 10 and base station device 20. Examples of physical channels include the Physical Downlink Control Channel (PDCCH), the Physical Broadcast Channel (PBCH), and the Physical Uplink Control Channel (PUCCH).

[0094] The transport channel is a channel located at a higher layer than the physical channel and is mapped to the physical channel in the PHY layer. Multiple transport channels can be mapped to one physical channel. Examples of transport channels include the downlink shared channel (DL-SCH) and the uplink shared channel (UL-SCH). For example, data in the downlink is also referred to as DL-SCH data. In addition, for example, data in the uplink can also be referred to as UL-SCH data. Here, the DL-SCH data includes user data in the downlink. In addition, the UL-SCH data includes user data in the uplink.

[0095] Logical channels are located above transport channels and are mapped to transport channels at the MAC layer. Multiple logical channels can be mapped to a single transport channel, or a single logical channel can be mapped to multiple transport channels. Logical channels are categorized by the characteristics of the information they transmit. Examples of logical channels include the Broadcast Control Channel (BCCH), the Common Control Channel (CCCH), and the Dedicated Control Channel (DCCH).

[0096] Base station device 20 uses the PDCCH, which is a physical channel, to transmit downlink control information (DCI) to terminal device 10. DCI includes information related to downlink and uplink resource allocation for terminal device 10 and control information for terminal device 10. DCI is mapped to PDCCH and is equivalent to layer 1 signaling.

[0097] Here, one or more formats may also be specified for the transmission of DCI in the PDCCH. The format specified for the transmission of DCI in the PDCCH can be referred to as a DCI format. For example, the DCI format may also include a DCI format for scheduling of a physical downlink shared channel (PDSCH) (for example, a format referred to as DCI format 1_0, DCI format 1_1, and / or DCI format 1_2). In addition, for example, the DCI format may also include a DCI format for scheduling of a physical uplink shared channel (PUSCH) (for example, a format referred to as DCI format 0_0, DCI format 0_1, and / or DCI format 0_2). In addition, the DCI format may also include a DCI format that is not used for scheduling of PDSCH and / or PUSCH. The DCI format used for scheduling of PDSCH and / or PUSCH can be referred to as a scheduling DCI format. The DCI format that is not used for scheduling of PDSCH and / or PUSCH can be referred to as a non-scheduled DCI format. In this embodiment, for convenience of explanation, “DCI format” may be simply referred to as “PDCCH.” Also, “DCI generated in accordance with the DCI format” may be simply referred to as “DCI format.”

[0098] For example, the base station device 20 may also configure the terminal device 10 to monitor (i.e., monitor) the frequency domain resources and / or time domain resources of the candidate set of the PDCCH. For example, the frequency domain resources of the candidate set of the PDCCH monitored by the terminal device 10 can be called a control resource set (COntrol REsource SET, CORESET). In addition, the time domain resources of the candidate set of the PDCCH monitored by the terminal device 10 can be called a search space set (Search Space Set, SSS). The terminal device 10 may also monitor the candidate set of the PDCCH through one or more CORESETs in the DL-BWP of the service cell configured with PDCCH monitoring according to the corresponding search space set. Here, monitoring may include attempting to decode each of the PDCCH candidates in accordance with the monitored DCI format. The above configuration can be called blind decoding.

[0099] Here, a CRC (Cyclic Redundancy Check) scrambled by RNTI (Radio Network Temporary Identifier) ​​may also be added to the DCI (or DCI format) sent via the PDCCH. CRC can also be referred to as a CRC parity bit. Multiple types of RNTIs are specified. For example, the base station device 20 may also configure each RNTI by sending an RRC message including at least one of information representing C-RNTI (Cell-RNTI, Cell Radio Network Temporary Identifier), information representing MCS-C-RNTI (Modulation and Coding Scheme Cell-RNTI, Modulation and Coding Scheme Cell Radio Network Temporary Identifier), and information representing CS-RNTI (Configured Scheduling-RNTI). That is, a CRC scrambled by at least one of C-RNTI, MCS-C-RNTI, and CS-RNTI may also be added to the DCI (or DCI format) sent via the PDCCH.

[0100] The terminal device 10 may also monitor (and / or receive) the PDCCH and detect (and / or receive) the DCI format.

[0101] Terminal device 10 uses the PUCCH, a physical channel, to send uplink control information (UCI) to base station device 20. UCI includes control information such as scheduling requests (SRs), HARQ ACK / Nacks, and channel state information (CSI). UCI is mapped to the PUCCH or PUSCH and is equivalent to layer 1 signaling.

[0102] The base station device 20 uses the DL-SCH as a transport channel to transmit a MAC layer control element (CE) to the terminal device 10. The downlink MAC CE is mapped to the PDSCH via the DL-SCH, which corresponds to layer 2 signaling.

[0103] Terminal device 10 uses the UL-SCH, a transport channel, to transmit MAC layer control elements (CEs) to base station device 20. Uplink MAC CEs include control information such as buffer status reports (BSRs). Uplink MAC CEs are mapped to the PUSCH via the UL-SCH, representing layer 2 signaling.

[0104] The base station device 20 uses the BCCH as a logical channel to send (or broadcast) system information (SI) to the terminal device 10. SI includes minimum system information (MSI) and other system information (OSI). MSI includes a master information block (MIB) and system information block 1 (SIB1). SIB1 can be called remaining minimum system information (RMSI). OSI includes system information blocks (SIB2 to SIB1) other than SIB1. In BCCH, MIB is mapped to PBCH via BCH (Broadcast CHannel), and SIB is mapped to PDSCH via DL-SCH.

[0105] The base station device 20 uses the signaling radio bearer (SRB) established between the terminal device 10 and the base station device 20 in the RRC layer to send the control information in the RRC layer to the terminal device 10. Hereinafter, the message exchanged between the base station device 20 and the terminal device 10 in the RRC layer can be referred to as an RRC message. There are multiple categories of SRBs (for example, SRB0, SRB1, SRB2, SRB3, SRB4). In addition to being used for sending and receiving RRC messages, SRB is also used for sending and receiving NAS messages including control information in the NAS layer. In the transmission of RRC messages from the base station device 20 to the terminal device 10, CCCH or DCCH is used. CCCH and DCCH are respectively mapped to PDSCH via DL-SCH. RRC messages are equivalent to layer 3 signaling.

[0106] As an example of a downlink RRC message, the RRC Reconfiguration message will be described. The RRC Reconfiguration message is an RRC message sent from base station device 20 to terminal device 10 using SRB1 or SRB3. The DCCH is used to transmit the RRC Reconfiguration message. The RRC Reconfiguration message is used to reconfigure or modify the connection between base station device 20 and terminal device 10.

[0107] Terminal device 10 uses the aforementioned SRB to transmit an RRC message to base station device 20. The CCCH or DCCH is used to transmit the RRC message from terminal device 10 to base station device 20. The CCCH and DCCH are mapped to the PUSCH via the UL-SCH, respectively. The RRC message corresponds to layer 3 signaling.

[0108] As an example of an uplink RRC message, the UECapabilityInformation message is described below. This message is an RRC message sent from terminal device 10 to base station device 20 using SRB1. The DCCH is used to transmit this message. The UECapabilityInformation message is used to notify base station device 20 of information related to the radio access capability of terminal device 10.

[0109] As an example of an uplink RRC message, the following describes a User Equipment Assistance Information (UEAssistanceInformation) message. This message is an RRC message sent from terminal device 10 to base station device 20 using SRB1 or SRB3. The DCCH is used to transmit the UEAssistanceInformation message. The UEAssistanceInformation message is used to notify base station device 20 of various information related to terminal device 10 (UE assistance information).

[0110] 1.4. Uplink Scheduling

[0111] 1.4.1. Dynamic Grant (DG)

[0112] DG is a scheduling method for allocating wireless resources for PUSCH in accordance with the process of uplink authorization. The base station device 20 sends an uplink authorization to the terminal device 10 via PDCCH. The terminal device 10 transmits PUSCH in accordance with the uplink authorization. For example, the base station device 20 may use a DCI format accompanied by a CRC encrypted by C-RNTI and / or MCS-C-RNTI (i.e., a DCI format for scheduling PUSCH) to allocate wireless resources for PUSCH, and the terminal device 10 may use the allocated wireless resources for PUSCH to perform uplink transmission. Here, the new data indicator included in the DCI format to which the CRC encrypted by C-RNTI and / or MCS-C-RNTI is added may also be set to 0 or 1. Alternatively, the base station device 20 may allocate PUSCH radio resources using a DCI format accompanied by a CRC scrambled by the CS-RNTI (i.e., a DCI format for scheduling PUSCH), and the terminal device 10 may perform uplink transmission using the allocated PUSCH radio resources. Here, the new data indicator included in the DCI format accompanied by a CRC scrambled by the CS-RNTI may also be set to 1.

[0113] 1.4.2. Configured Grant (CG)

[0114] CG is a scheduling method for allocating PUSCH radio resources without the above-mentioned dynamic uplink grant process. The base station device 20 transmits an RRC message including CG parameters to the terminal device 10. The CG parameters are included in the ConfiguredGrantConfig IE, which is an example of an RRC information element (IE).

[0115] For example, the base station device 20 may also send an RRC message including CG-related parameters (i.e., ConfiguredGrantConfig IE) for a certain service cell to the terminal device 10. That is, the CG-related parameters (i.e., ConfiguredGrantConfig IE) may also be configured for each of one or more service cells. In addition, the base station device 20 may also send an RRC message including CG-related parameters (i.e., ConfiguredGrantConfig IE) for a certain UL-BWP to the terminal device 10. That is, the CG-related parameters (i.e., ConfiguredGrantConfig IE) may also be configured for each of one or more UL-BWPs. The terminal device 10 may also identify the CG-related parameters (i.e., ConfiguredGrantConfig IE) for each of one or more UL-BWPs.

[0116] The ConfiguredGrantConfig IE includes a parameter periodicity related to the period of transmission using the PUSCH. In addition, the parameter periodicity is configured in units of the number of time slots or the number of symbols. Alternatively, the parameter periodicity can also be configured in units of frames per second (FPS).

[0117] One or more transmission occasions for PUSCH are configured through CG. The terminal device 10 may also transmit PUSCH at the transmission occasion. Here, the transmission occasion may also be expressed as a resource (for example, a PUSCH resource). In addition, the terminal device 10 supports one TB (Transport Block) at one transmission occasion. That is, one TB is sent at one transmission occasion.

[0118] CG includes two types: Type 1 and Type 2. Type 1 and Type 2 are described below.

[0119] (1) Type 1

[0120] In Type 1, the terminal device 10 transmits a signal (for example, transmission in the PUSCH) at a configured period without being triggered by DCI (for example, a DCI format for scheduling the PUSCH).

[0121] like Figure 9As shown, the communication unit 220 of the base station device 20 sends an RRC message including the parameters of the CG to the terminal device 10 (S901).

[0122] The control unit 110 of the terminal device 10 performs the periodic transmission action of PUSCH according to the parameters of CG (S902). For example, the terminal device 10 may also store (store) the RRC message including the parameters of CG as a configured uplink grant. Here, the RRC message including the parameters of CG used in the scheduling of PUSCH is also referred to as an uplink grant. In addition, the terminal device 10 may consider that after being configured with the uplink grant for CG type 1, the uplink grant is generated (repeatedly generated) in sequence under the SFN and / or time slot number that satisfies the predetermined formula. That is, the terminal device 10 may consider that the stored uplink grant is generated in sequence under the SFN and / or time slot number that satisfies the predetermined formula, thereby performing the transmission of PUSCH.

[0123] The control unit 210 of the base station device 20 performs a periodic reception operation of the PUSCH (S903). The control unit 210 can be considered to sequentially generate (repeatedly generate) uplink grants stored in the terminal device 10 under SFNs and / or time slot numbers that satisfy a predetermined formula, thereby performing PUSCH reception.

[0124] In addition, with respect to more than one serving cell or more than one UL-BWP, multiple CGs may be configured for the terminal device 10. For example, the base station device 20 may also send an RRC message including parameters related to the first CG (e.g., first CG configuration) and parameters related to the second CG (e.g., second CG configuration) to the terminal device 10. The terminal device 10 may also perform transmission of a first PUSCH associated with the first CG (e.g., first CG configuration) and perform transmission of a second PUSCH associated with the second CG (e.g., second CG configuration).

[0125] (2) Type 2

[0126] In type 2, the terminal device 10 transmits a signal (for example, transmission in PUSCH) at a configured period according to activation using DCI scrambled by CS-RNTI (for example, DCI format for scheduling PUSCH).

[0127] like Figure 10As shown, the communication unit 220 of the base station device 20 sends an RRC message including the parameters of the CG to the terminal device 10 (S1001). Next, the communication unit 220 sends the DCI encrypted by the CS-RNTI to the terminal device 10 (S1002). As a result, the periodic transmission action of the terminal device 10 using the PUSCH is activated.

[0128] The control unit 110 of the terminal device 100 performs a periodic transmission action of the PUSCH according to the parameters and / or DCI of the CG (S1003). For example, when the DCI to which the CRC encrypted by the CS-RNTI is added (i.e., the DCI used in the scheduling of the PUSCH) indicates the activation of the CG (i.e., when the PDCCH indicates the activation of the CG), the terminal device 10 may also store (store) the DCI as a configuration uplink grant. Here, the DCI (DCI format) used in the scheduling of the PUSCH is also referred to as an uplink grant. In addition, the case where the DCI indicates the activation of the CG may also include the case where the predetermined information included in the DCI (e.g., each information field in one or more information fields) is set to a predetermined value. For example, the case where the DCI indicates the activation of the CG may also include the case where the new data indicator included in the DCI is set to 0. In addition, the terminal device 10 may consider that after the uplink grant is configured for CG type 2, the uplink grant is sequentially generated (repeatedly generated) under the SFN and / or time slot number that satisfies the predetermined formula. That is, the terminal device 10 may consider that the stored uplink grants are generated sequentially under the SFN and / or time slot number that satisfies a predetermined formula, thereby performing PUSCH transmission.

[0129] The control unit 210 of the base station device 20 performs a periodic reception operation of the PUSCH (S1004). The control unit 210 can be considered to sequentially generate (repeatedly generate) uplink grants stored in the terminal device 10 under SFNs and / or time slot numbers that satisfy a predetermined formula, thereby performing PUSCH reception.

[0130] In addition, with respect to more than one serving cell or more than one UL-BWP, multiple CGs may also be configured for the terminal device 10. For example, the base station device 20 may also send an RRC message including parameters related to the first CG (e.g., first CG configuration) and parameters related to the second CG (e.g., second CG configuration) to the terminal device 10. The terminal device 10 may also perform transmission of a first PUSCH associated with the first CG (e.g., first CG configuration) when the first CG (e.g., first CG configuration) is activated through DCI. The terminal device 10 may also perform transmission of a second PUSCH associated with the second CG (e.g., second CG configuration) when the second CG (e.g., second CG configuration) is activated through DCI. For example, in order to activate the transmission of each of the multiple PUSCHs, information indicating the index of the CG configuration (e.g., the value of the information indicating the index of the CG configuration) may also be included in the DCI. For example, the terminal device 10 may also perform (or activate) transmission of PUSCH based on the first CG configuration when receiving DCI including information indicating the index of the first CG configuration (for example, information indicating the index "0" of the first CG configuration). In addition, the terminal device 10 may also perform (or activate) transmission of PUSCH based on the second CG configuration when receiving DCI including information indicating the index of the second CG configuration (for example, information indicating the index "1" of the second CG configuration). Here, the value of the information indicating the index of the CG configuration (for example, the value of the information indicating the index of the first CG configuration and / or the value of the information indicating the index of the second CG configuration) may also be set in the field of information indicating the HARQ process number.

[0131] 1.5. Resource Allocation

[0132] In the DG and CG, the terminal device 10 may also receive information for determining resource allocation for uplink transmission (hereinafter also referred to as table-related information) from the base station device 20. For example, the above table is a TDRA (Time Domain Resource Assignment) table. Below, the above table is referred to as the "first table". In addition, the above information is referred to as "first table information". For example, the "first table information" may also be included in the parameters related to the PUSCH. That is, the base station device 20 may also send an RRC message including one or more parameters for TDRA for PUSCH transmission (for example, table-related information), and the terminal device 10 determines the resources in the time domain for PUSCH transmission based on the one or more parameters for TDRA. The following describes the case where one or more parameters for TDRA are specified as a table, but one or more parameters for TDRA may be specified in any form. For example, an index (and / or order) may also be specified corresponding to each of the one or more parameters for TDRA, and correspond to the index in the table described later.

[0133] In the first table, one index (or value) is associated with one PUSCH transmission opportunity. Specifically, one index (or value) is associated with one or more parameters related to resources used for PUSCH transmission.

[0134] For example, the first table may include at least one parameter from the following (a1) to (a3).

[0135] (a1) k2: Information associated with the time slot in which uplink transmission (i.e., transmission of PUSCH) is performed. Specifically, k2 may also represent the offset between the time slot in which the RRC message or DCI is received and the time slot in which the PUSCH is transmitted. Here, receiving the RRC message or DCI may also include considering that an uplink grant is generated. In addition, performing uplink transmission (i.e., transmission of PUSCH) may also include the transmission timing of the uplink. That is, the offset represented by k2 may also include the offset between the time slot in which the RRC message or DCI is received and the transmission timing of the PUSCH. As k2, a default value may also be used according to the SCS.

[0136] (a2) SLIV (Start and Length Indicator Value): Information indicating the combination of the starting symbol position S and the consecutive symbol lengths L from the starting symbol position S in the time slot where uplink transmission (i.e., PUSCH transmission) is performed. The time slot where uplink transmission (i.e., PUSCH transmission) is performed may also include the time slot of the uplink transmission opportunity (i.e., PUSCH transmission opportunity). As an alternative to SLIV, the starting symbol position S and the symbol length L may be indicated separately.

[0137] (a3) Mapping Type: information indicating the mapping type of uplink transmission (ie, PUSCH transmission). Mapping types include Type A and Type B.

[0138] Similarly, the first table information may also include at least one parameter from (a1) to (a3) ​​above. The base station device 20 may also send an RRC message including the first table information to the terminal device 10. The first table information may be included in a parameter related to the PUSCH (e.g., the PUSCH-ConfigCommon IE). The terminal device 10 configures the first table based on the first table information.

[0139] The first table information can be configured per cell, per UE, and / or per DCI format. That is, multiple first tables can also be configured. In addition, a default table can also be used as the first table.

[0140] The table actually applied (or selected) can also be determined from a plurality of first tables based on the following (b1) to (b4).

[0141] (b1) DCI format

[0142] (b2)RNTI

[0143] (b3) PDCCH Search Space

[0144] (b4) Whether the information in the first table is configured by cell, by UE, and / or by DCI format

[0145] The following describes an example of configuring the first table inherent to the cell. The first table inherent to the cell can also be configured using the PUSCH-ConfigCommon IE included in the RRC message. The base station device 20 sends the RRC message including the PUSCH-ConfigCommon IE to the terminal device 10. The PUSCH-ConfigCommon IE includes one or more PUSCH-TimeDomainResourceAllocationList IEs as the first table information. The PUSCH-TimeDomainResourceAllocationList IE includes k2, mappingType (mapping type) and startSymbolAndLength. k2 is equivalent to the above (a1). mappingType is equivalent to the above (a3). startSymbolAndLength is equivalent to the above (a2).

[0146] like Figure 11 As shown, the terminal device 10 may also configure the first table based on the first table information. The first table includes information indicating a row index (Row Index) for referencing each row. Figure 11 In the example, the row index is associated with the parameters (a1) to (a3). In addition, j, which is the value of k2, is the parameter μ representing the SCS of the PUSCH. PUSCH The value determined by . That is, j, which is represented by the value of k2, is determined based on the SCS configured for the UL-BWP performing the corresponding PUSCH transmission. For example, base station device 20 may also transmit an RRC message including information indicating the SCS for each of one or more UL-BWPs to terminal device 10. Base station device 20 transmits information indicating row index m to terminal device 10.

[0147] In the case of type 1 of CG, the base station device 20 sends an RRC message including information indicating the row index m to the terminal device 10. For example, the information indicating the row index m may be included in a parameter related to the CG (i.e., ConfiguredGrantConfigIE). The information indicating the row index m may also be represented by the timeDomainAllocationIE included in the ConfiguredGrantConfigIE. In addition, the size (i.e., the number of bits or the bit width) of the information (IE) indicating the row index m may also be determined based on the number of entries in the first table, for example. Figure 11In the example, the number of entries in the first table is 30, so the size of the information indicating row index m may also be 5 bits. When terminal device 10 receives an RRC message including information indicating row index m from base station device 20, it may also refer to row index m+1 of the first table. Terminal device 10 may also use parameters (a1) to (a3) ​​associated with row index m+1 of the first table to determine resources for uplink transmission.

[0148] In the case of type 2 of CG, the base station device 20 sends a DCI including information indicating the row index m (i.e., an information field set to a value indicating the row index m) to the terminal device 10. That is, the information indicating the row index m can also be represented by a value set in the TDRA field of the DCI. Here, the size of the TDRA field (i.e., the number of bits or the bit width) can also be determined based on the number of entries in the first table, for example. Figure 11 In the example, the number of entries in the first table is 30, so the size of the TDRA field may also be 5 bits. When the terminal device 10 receives DCI including information indicating row index m from the base station device 20, it may also refer to row index m+1 of the first table. The terminal device 10 may also use parameters (a1) to (a3) ​​associated with row index m+1 of the first table to determine resources for uplink transmission.

[0149] Furthermore, in the DG, the base station device 20 is able to use a single DCI to schedule multiple transmission opportunities of the PUSCH. The terminal device 10 may also receive information related to a table for determining resource allocation for uplink transmission from the base station device 20. The above table is a TDRA table, hereinafter referred to as the "second table". In addition, the above information is referred to as "second table information". That is, the second table information may also include at least one parameter from (a1) to (a3) ​​above. For example, the "second table information" may also be included in the parameters related to the PUSCH.

[0150] In the second table, one index (or value) is associated with one or more PUSCH transmission opportunities. Specifically, one index (or value) is associated with one or more parameters related to resources used for transmission of one or more PUSCHs.

[0151] For example, the base station device 20 may also send an RRC message including the second table information to the terminal device 10. The second table information may be included in parameters related to the PUSCH (e.g., PUSCH-Config IE). In addition, the second table information may be configured per cell, per UE, and / or per DCI format. That is, multiple second tables may also be configured. In addition, a default table may also be used as the second table.

[0152] For example, the PUSCH-Config IE may also include the pusch-TimeDomainAllocationListForMultiPUSCH IE as the second table information. The pusch-TimeDomainAllocationListForMultiPUSCH IE may also include one or more PUSCH-TimeDomainResourceAllocation IEs. The PUSCH-TimeDomainResourceAllocation IE may also include k2 and one or more puschAllocationList IEs. The puschAllocationList IE may include at least one of mappingType, startSymbolAndLength, startSymbol, and length. k2 is equivalent to (a1) above. mappingType is equivalent to (a3) ​​above. startSymbolAndLength, startSymbol, and length are equivalent to (a2) above. In this example, one k2 may also be associated with multiple PUSCH-AllocationIEs. That is, one k2 may also be configured for multiple PUSCH-AllocationIEs in common. In this case, k2 may also represent the time slot of the initial transmission opportunity among the transmission opportunities of consecutive PUSCHs from 2 to 8. That is, the terminal device 10 can also perform uplink transmission at consecutive PUSCH transmission opportunities based on the second table information.

[0153] like Figure 12 As shown, the terminal device 10 may also configure the second table based on the second table information. The second table includes information indicating a row index for referencing each row. Figure 12 In the example, a row index is associated with multiple transmission opportunities of PUSCH. For example, in a case where the row index "10" in the second table is represented by information representing the row index included in the DCI (for example, a value set in the information representing the row index), multiple transmission opportunities corresponding to the row index "10" are scheduled. Specifically, in the case of representing the row index "10", the terminal device 10 may also use 4 parameter sets corresponding to each of the 4 transmission opportunities. Parameters (a2) and (a3) ​​are configured separately for each of the 4 transmission opportunities. In addition, parameter (a1) is configured commonly for the 4 transmission opportunities.

[0154] In another example, parameter (a1) may be configured separately for each of the four transmission opportunities. In this case, the parameter extendedK2 included in the PUSCH-Allocation IE may also be used. That is, the base station device 20 may also configure parameters (a1) to (a3) ​​separately or collectively for multiple PUSCH transmission opportunities.

[0155] The base station device 20 transmits the DCI including the information indicating the row index m to the terminal device 10. The row index m may also be represented by a value set in the TDRA field of the DCI. The size of the TDRA field may also be determined based on the number of entries in the second table, for example. For example, in the case where the format of the DCI is DCI format 0_1 ​​and / or DCI format 0_2, the size of the TDRA field may also be determined based on the number of entries in the second table. Figure 12 In the example, the number of entries in the second table is 15, so the size of the TDRA field may also be 4 bits. When the terminal device 10 receives DCI including information indicating row index m from the base station device 20, it may also refer to row index m+1 of the second table. The terminal device 10 may also use parameters (a1) to (a3) ​​associated with row index m+1 of the second table to determine resources for uplink transmission.

[0156] For example, the base station device 20 transmits DCI including information set to a value indicating the row index "9" to the terminal device 10. The terminal device 10 refers to Figure 12 The row index in the second table shown is "10." This row is associated with four parameter sets. Therefore, the terminal device 10 determines (or determines) that four transmission opportunities for the PUSCH are scheduled. The terminal device 10 uses the four parameter sets associated with the row index "10" to determine the resources for the uplink transmission.

[0157] 1.6. UCI Transmission

[0158] The terminal device 10 may also transmit UCI in a PUSCH scheduled by the CG (ie, CG PUSCH).

[0159] NR-U (unlicensed) was introduced as a 5G specification for using unlicensed spectrum channels. In addition, unlicensed spectrum channels can also be rewritten as shared spectrum channels.

[0160] In NR-U, the UCI transmitted in the PUSCH scheduled by the CG is also called "CG-UCI". The CG-UCI may include specific fields. For example, it is assumed that the parameter cg-RetransmissionTimer of the upper layer (i.e., the RRC layer) is configured. In this case, the CG-UCI may include at least one field from (c1) to (c4).

[0161] (c1)HARQ Process Number

[0162] (c2) Redundancy Version (RV)

[0163] (c3) New Data Indicator (NDI)

[0164] (c4) Channel Occupancy Time (COT) sharing information

[0165] In addition, when the high-level parameter cg-UCI-Multiplexing is configured, CG-UCI may also include the following field (c5) in addition to (c1) to (c4).

[0166] (c5)HARQ-Ack bit

[0167] 1.7. Extended Reality (XR)

[0168] This section describes the characteristics of traffic generated in XR. In XR, multiple types of data (such as animation data, audio data, user data, and control data) are sent and received concurrently. The multiple data flows corresponding to these data streams have different traffic characteristics and Quality of Service (QoS) requirements.

[0169] In the transmission and reception timing of the above-mentioned data, time shifts such as jitter, variability, and fluctuation may occur due to factors such as video and audio encoding and network delay.

[0170] Reference 1 states that the following definition can be introduced regarding transmission and reception in XR.

[0171] [Reference 1] 3GPP TR 23.700-60 V1.1.0 (2022-09)

[0172] PDU set: A PDU set consisting of one or more PDUs that carry a payload of information generated at the application layer. The application layer corresponds to, for example, a frame or video slice in an XR service.

[0173] Data Burst: A collection of data multiplex PDUs generated and sent by an application in a short period of time.

[0174] Furthermore, in XR, as part of the aforementioned QoS requirements, the Packet Delay Budget (PDB) requirement is explored. The PDB is the upper bound of the packet delay allowed between the terminal device 10 and the UPF. Furthermore, Reference 1 describes the following new QoS parameters that can be introduced.

[0175] PDU-Set Delay Budget (PSDB): is the upper bound of the delay time of the PDU set allowed between the terminal device 10 and the UPF.

[0176] PDU-Set Error Rate (PSER): The upper bound of the error rate calculated between a PDU set processed by the sender and all PDUs in the PDU set that were not successfully delivered to the corresponding upper layer of the receiver.

[0177] 1.8. CG Expansion

[0178] It is assumed that XR will be used under the above requirements. In conjunction with this, for uplink transmission from terminal devices, the use of CG-based scheduling instead of DG-based scheduling is being studied. Figure 13As shown, in the past, one transmission opportunity was configured in a single period of the CG. The above period is equivalent to the period (periodicity) of the parameters of the CG described above (i.e., parameters related to the CG). As described above, the base station device 20 may also include the parameters of the CG including information for indicating the period and / or offset in the RRC message for transmission, and configure the period and / or offset for the transmission of the CG PUSCH. In addition, the terminal device 10 may also perform periodic transmission of the CG PUSCH in accordance with the information for indicating the period and / or offset included in the RRC message. Here, one transmission opportunity may also include a transmission opportunity corresponding to the transmission of one transport block. In addition, multiple transmission opportunities may also include transmission opportunities corresponding to the transmission of one or more transport blocks.

[0179] exist Figure 13 In the configuration of , it is possible that the XR requirements cannot be met. Therefore, in this embodiment, if Figure 14 As shown in FIG, multiple transmission opportunities are configured in a single period for PUSCH. Figure 14 In the example of , the number of transmission opportunities included in one period is Nt=3.

[0180] In such a configuration, the terminal device 10 may not use at least one of a plurality of transmission opportunities (e.g., a plurality of transmission opportunities included in a time period) in uplink transmission. Hereinafter, such unused transmission opportunities are referred to as "unused occasions" or "unused transmission occasions."

[0181] The terminal device 10 transmits information on unused timings among a plurality of transmission timings to the base station device 20. In addition, such information on unused timings is sometimes referred to as "dynamic indication of unused timings."

[0182] For example, the terminal device 10 sends UCI including information related to unused occasions to the base station device 20. The UCI including information related to unused occasions may also be referred to as UTO-UCI (Unused Transmission Occasion-Uplink Control Information). The terminal device 10 may also use at least one of the multiple transmission occasions configured by the CG (i.e., CG PUSCH) to send UCI. Alternatively, the terminal device 10 may also use resources other than the CG PUSCH (e.g., resources of the PUCCH) to send UCI. In such a configuration, the terminal device 10 and / or the base station device 20 are required to determine a process for the size (i.e., the number of bits or the bit width) of the information related to the unused occasions.

[0183] In this embodiment, the terminal device 10 receives configuration information associated with multiple transmission opportunities included in one time period in the CG. Below, for ease of expression, "configuration information associated with multiple transmission opportunities included in one time period in the CG" is referred to as "configuration information."

[0184] The configuration information may also be configured for each of one or more serving cells. In another example, the configuration information may also be configured for each of one or more UL-BWPs. In addition, the configuration information may also be configured for each of one or more CGs (i.e., CG configurations). For example, the configuration information may also be configured for each of one or more type 1 CG configurations. In addition, the configuration information may also be configured for each of one or more type 2 CG configurations. For example, the base station device 20 may also send an RRC message including the configuration information. The terminal device 10 may also receive the configuration information included in the RRC message. For example, the base station device 20 may also send an RRC message including information for determining the number of bits of information related to unused occasions (for example, information indicating the number of bits of information related to unused occasions). In addition, the terminal device 10 may also determine the number of bits of information related to unused occasions based on the information for determining the number of bits of information related to unused occasions included in the RRC message. For example, the number of bits of information related to unused occasions may also be the number of bits of information related to unused occasions in one time period. In addition, as described later, the number of bits of information on unused opportunities may be the number of bits of information on unused opportunities in a plurality of time slots.

[0185] The terminal device 10 uses the configuration information to determine the size (i.e., the number of bits or bit width) of the information related to the unused opportunities. Similarly, the base station device 20 uses the configuration information to determine (or configure) the size of the information related to the unused opportunities. In other words, the configuration information can also be used to determine (or configure) the size of the information related to the unused opportunities.

[0186] Hereinafter, first to fourth schemes will be described as schemes for the process of determining the size of the information related to the unused opportunity.

[0187] (1) First option

[0188] The configuration information may also include table information for configuring a table related to resources of multiple transmission opportunities included in one time period in the CG and / or indication information (indication information) showing an index (or value) for reference to the above table.

[0189] Hereinafter, the above table is referred to as the "third table". The third table may also be a TDRA table. In addition, the above table information is referred to as "third table information". In the third table, one index (or value) is associated with one or more PUSCH transmission timings.

[0190] Specifically, in the third table, one index is associated with one or more parameters. The parameters are parameters related to the resource of the transmission opportunity, and may include, for example, at least one of the following (d1) to (d7).

[0191] (d1) Information related to the time slot for uplink transmission (i.e., transmission of PUSCH). Specifically, (d1) may also be the offset between the time slot in which the RRC message or DCI is received and the time slot in which the PUSCH is transmitted. Here, receiving the RRC message or DCI may also include considering that an uplink authorization has been generated. In addition, performing uplink transmission (i.e., transmission of PUSCH) may also include the transmission timing of the uplink. That is, the offset represented by k2 may also include the offset between the time slot in which the RRC message or DCI is received and the transmission timing of the PUSCH. For example, (d1) may also be the k2 of (a1) above.

[0192] (d2) The starting symbol of the uplink transmission (i.e., the PUSCH transmission). The starting symbol of the uplink transmission (i.e., the PUSCH transmission) may also include the starting symbol of the uplink transmission timing (i.e., the PUSCH transmission timing). Specifically, (d2) may also be the starting symbol position S of (a2) above.

[0193] (d3) The length from the starting symbol. The length from the starting symbol may also include the length of the uplink transmission opportunity (i.e., the PUSCH transmission opportunity) from the starting symbol. Specifically, (d2) may also be the symbol length L in (a2) above. In addition, SLIV may also be used as a combination of (d2) and (d3).

[0194] (d4) Mapping type of uplink transmission (i.e., PUSCH transmission). Specifically, (d4) may also be the mapping type of (a3) ​​above. That is, the mapping type may also include type A and type B.

[0195] (d5) Redundancy Version (RV). This indicates the redundancy version number corresponding to the UL-SCH information (uplink data, uplink transmission timing, or PUSCH transmission). For example, if a redundancy version number is configured, a transport block may be repeatedly transmitted at one or more PUSCH transmission timings according to the redundancy version number.

[0196] (d6) Information related to the offset (or gap) between multiple uplink transmissions (i.e., multiple PUSCH transmissions). The information may also include the length (or period) between the multiple uplink transmissions. In addition, the information may also include the offset (gap, length or period) between the transmission opportunities of the multiple uplinks (i.e., the transmission opportunities of the PUSCH). For example, the offset may also be represented by the number of time slots and / or the number of symbols. Specifically, when three PUSCH transmission opportunities (the first transmission opportunity, the second transmission opportunity, and the third transmission opportunity) are configured in a certain time period of the CG, the value of the offset between the first transmission opportunity and the second transmission opportunity and / or the value of the offset between the second transmission opportunity and the third transmission opportunity may also be represented. For example, the value of a certain offset may also be configured and applied jointly as the offset between the first transmission opportunity and the second transmission opportunity and the offset between the second transmission opportunity and the third transmission opportunity. In addition, the terminal device 10 may also perform uplink transmission (i.e., PUSCH transmission) at multiple consecutive PUSCH transmission opportunities without configuring the offset.

[0197] (d7) Information related to an offset for determining the position of a time slot and / or symbol for each of one or more uplink transmission opportunities. This information may also include an offset for determining the position of each of multiple uplink transmissions (i.e., PUSCH transmissions). This offset may also be the fifth information described later (e.g., timeDomainOffset). For example, this offset may also be a parameter used in a predetermined formula for determining the position of a time slot and / or symbol for each of one or more uplink transmission opportunities.

[0198] Similarly, the third table information may also include at least one parameter from (d1) to (d7). The terminal device 10 uses the third table information to configure the third table. For example, when the third table information is included in the RRC message, the terminal device 10 may also perform PUSCH transmission based on the third table information. That is, when the third table information is included in the RRC message, the terminal device 10 may also perform PUSCH transmission at one or more PUSCH transmission opportunities in one CG period. That is, when the third table information is included in the RRC message, the terminal device 10 may also send one or more transmission blocks in one CG period. Here, when the third table information is not included in the RRC message, the terminal device 10 may also perform PUSCH transmission at one transmission opportunity in one CG period. That is, when the third table information is not included in the RRC message, the terminal device 10 may also send one transmission block in one CG period.

[0199] In addition, the terminal device 10 may also perform PUSCH transmission based on the third table information included in each CG configuration in a plurality of CG configurations. Here, the terminal device 10 may also perform the transmission of a certain PUSCH when a conflict occurs in the transmission of multiple PUSCHs. That is, the terminal device 10 may also perform the transmission of a certain transport block when a conflict occurs in the transmission of multiple PUSCHs. Here, the situation where the transmission of multiple PUSCHs conflicts may also include the situation where the transmission of multiple PUSCHs occurs under the same time domain resources (for example, time slots and / or symbols). In addition, the situation where the transmission of multiple PUSCHs conflicts may also include the situation where the transmission timing of multiple PUSCHs is configured under the same time domain resources (for example, time slots and / or symbols).

[0200] For example, when a conflict occurs between the transmission of multiple PUSCHs, the terminal device 10 may also determine the transmission of the PUSCH to be performed (or the transmission timing for the transmission of the PUSCH) based on the information representing the index included in the CG configuration (i.e., the index of the CG configuration). For example, the transmission of one or more first PUSCHs (or the transmission timing of the first PUSCH) is configured using the first CG configuration including the index "0" (i.e., the parameter of the first CG), and the transmission of one or more second PUSCHs (or the transmission timing of the second PUSCH) is configured using the second CG configuration including the index "1" (i.e., the parameter of the second CG). When a conflict occurs between the transmission of the first PUSCH and the transmission of the second PUSCH, the terminal device 10 may also perform the transmission of one or more PUSCHs based on the first CG configuration including the index "0". That is, when a conflict occurs between the transmission of multiple PUSCHs, the terminal device 10 may also perform the transmission of one or more PUSCHs according to the parameters included in the CG configuration with the smallest (or largest) index value.

[0201] In addition, for example, the base station device 20 may also send an RRC message including information indicating the priority of the CG configuration. For example, the information indicating the priority of the CG configuration may also be configured for each CG configuration in the CG configuration (or, may also be included in each CG configuration in the CG configuration). In the event that a conflict occurs between the transmissions of multiple PUSCHs, the terminal device 10 may also perform the transmission of one or more PUSCHs based on the priority of the CG configuration. For example, in the event that a conflict occurs between the transmissions of multiple PUSCHs, the terminal device 10 may also perform the transmission of one or more PUSCHs according to the parameters included in the CG configuration with the highest (or lowest) priority among the CG configurations.

[0202] In addition, the terminal device 10 may also send information indicating the number of the redundant version corresponding to the information of the UL-SCH sent in the PUSCH. Specifically, for example, when the terminal device 10 has the information of UL-SCH for the first transmission opportunity (information of UL-SCH exists), the terminal device 10 may also include (map or multiplex) the information indicating the redundant version number "0" into the resources of the PUSCH under the first transmission opportunity. In addition, when the terminal device 10 does not have the information of UL-SCH for the first transmission opportunity (information of no UL-SCH) and has the information of UL-SCH for the second transmission opportunity, the terminal device 10 may also include the information indicating the redundant version number "0" into the resources of the PUSCH under the second transmission opportunity.

[0203] Furthermore, the third table information may be configured per cell, per UL-BWP, per UE, and / or per DCI format. That is, multiple third tables (i.e., multiple third table information) may also be configured. Furthermore, a default table may also be used as the third table.

[0204] The table actually applied (or selected) may also be determined from a plurality of third tables based on the following (e1) to (e4). That is, third table information may also be configured for each of the DCI formats used for scheduling PUSCH (e.g., DCI format 0_0, DCI format 0_1, and / or DCI format 0_2). That is, the terminal device may also determine corresponding third table information (e.g., parameters for TDRA) based on the DCI format used in scheduling (and / or activating) PUSCH transmission.

[0205] (e1)DCI format

[0206] (e2)RNTI

[0207] (e3)PDCCH search space

[0208] (e4) Whether the information in the third table is configured by cell, by UL-BWP, by UE, and / or by DCI format

[0209] At least one of the above parameters included in the third table is configured separately for each transmission opportunity of a plurality of transmission opportunities included in one time period. For example, an index received as indication information and a plurality of parameters (or a plurality of parameter sets) corresponding to each of a plurality of transmission opportunities may also be associated. Here, the number of parameters associated with the index is equivalent to the number of transmission opportunities Nt. Therefore, the terminal device 10 determines the size of the information related to the unused opportunity based on the number of parameters (or the number of parameter sets) associated with the index. For example, the terminal device 10 may also determine the size of the information related to the unused opportunity based on the number of at least one parameter among the above (d1) to (d7). That is, the terminal device 10 may also determine the size of the information related to the unused opportunity based on the number of entries of at least one parameter among the above (d1) to (d7) (that is, the number of parameters included (or recorded in the entries) in the third table information).

[0210] Here, the size of the information related to the unused opportunity can also be determined based on the number of transmission opportunities Nt and the number of time periods (i.e., CG time periods) Np. That is, the information related to the unused opportunity can also be used for the transmission opportunity of PUSCH in multiple time periods. For example, the base station device 20 can also send an RRC message including information indicating the number of time periods Np for determining the size of the information related to the unused opportunity. For example, the terminal device 10 can also determine the size of the information related to the unused opportunity by multiplying the number of transmission opportunities Nt by the number of time periods Np. Specifically, for example, in the case where "3" is indicated as the number of transmission opportunities Nt and "2" is indicated as the number of time periods Np, 6 bits (i.e., the number of bits obtained by multiplying the number of transmission opportunities Nt "3" and the number of time periods Nt "2") of information related to the unused opportunity can also be used.

[0211] As described above, the base station device 20 may also transmit an RRC message including one or more parameters (for example, one or more parameters included in the third table information) to configure one or more transmission opportunities in one time period for the terminal device 10. When the RRC message includes one or more parameters (for example, one or more parameters included in the third table information), the terminal device 10 may also perform PUSCH transmission at one or more transmission opportunities in one time period.

[0212] Here, the base station device 20 may also include information for indicating the transmission of information related to unused opportunities in the RRC message for transmission. That is, the base station device 20 may also separately configure the transmission of PUSCH under one or more transmission opportunities and the transmission of information related to unused opportunities. When the RRC message includes information for indicating the transmission of information related to unused opportunities, the terminal device 10 may also send information related to unused opportunities (for example, the information related to unused opportunities may also be included (or mapped or multiplexed) into the resources of PUSCH). For example, when the RRC message includes one or more parameters (for example, one or more parameters included in the third table information) and information for indicating the transmission of information related to unused opportunities, the terminal device 10 may also send information related to unused opportunities.

[0213] The information related to the unused opportunities can also be represented as a sequence. Alternatively, the information can be represented as a bit sequence (e.g., a bitmap). That is, the sequence can also be expressed as a bit sequence. For example, the information can also be represented as a bit sequence, where each bit of the bit sequence corresponds to each of a plurality of transmission opportunities and is used as information related to the unused opportunities (i.e., a dynamic indication). The details of the above sequence are described below.

[0214] Furthermore, the base station device 20 determines the size of the information related to the unused opportunity based on the configuration information (ie, the third table information and the instruction information) in the same manner as described above.

[0215] The following describes the specific process for each of CG type 1 and type 2. Figure 14 As in the example of , it is assumed that three transmission opportunities are configured in one period.

[0216] —Type 1

[0217] like Figure 15 As shown, the communication unit 220 of the base station device 20 sends an RRC message including parameters related to PUSCH to the terminal device 10 (S1501). The parameters related to PUSCH include third table information. The parameters related to PUSCH may also be PUSCH-Config IE. The third table information may also be included in PUSCH-Config IE. In addition, the third table information may also be included in an IE other than PUSCH-Config IE. Among the parameters related to PUSCH, parameters related to the CG including the third table information may also be included.

[0218] The communication unit 220 sends an RRC message including CG-related parameters to the terminal device 10 (S1502). The CG-related parameters include information indicating the row index m for referencing the third table. The CG-related parameters may also be ConfiguredGrantConfig IE. The information indicating the row index m may also be included in the ConfiguredGrantConfigIE. In addition, the information indicating the row index m may also be included in an IE other than the ConfiguredGrantConfig IE. In addition, the size of the information (IE) indicating the row index m (i.e., the number of bits or the bit width) may also be determined based on the number of entries in the third table, for example. That is, the size of the information indicating the row index m may also be determined based on the number of parameters (or parameter sets) in the third table (i.e., the number of parameters included (or recorded in entries) in the third table). In addition, the third table information may also be configured individually or collectively for each of one or more CG configurations (e.g., type 1 CG configuration and / or type 2 CG configuration).

[0219] The control unit 110 of the terminal device 10 configures the third table based on the third table information. In addition, the terminal device 10 may also perform PUSCH transmission (i.e., type 1 CG PUSCH transmission) based on the third table information. The third table information includes at least one of the parameters (d1) to (d7). The control unit 110 configures Figure 16The third table shown in FIG. In the third table, one row index is associated with one or more transmission opportunities. For example, the row index "1" is associated with a parameter set corresponding to one transmission opportunity included in one period. In addition, the row index "10" is associated with three parameter sets corresponding to three transmission opportunities included in one period. Figure 16 In the example of , the parameter (d1) (ie, k2) is commonly configured for the three transmission opportunities.

[0220] Assume that terminal device 10 receives an RRC message including information indicating row index m (=9). Control unit 110 references row index m+1 of the third table. Control unit 110 obtains three parameter sets corresponding to three transmission opportunities, associated with row index "10" of the third table. Control unit 110 uses these three parameter sets to determine the resources for each uplink transmission.

[0221] The control unit 110 may also determine the size of the information related to unused opportunities based on the number of valid (or available) parameters associated with the row index "10". In this example, the number of parameters (d2) associated with the row index "10" is 3. The control unit 110 may also determine (or determine) that the number of transmission opportunities Nt is "3" based on the number of parameters (d2) associated with the row index "10". The control unit 110 may also determine the size of the information related to unused opportunities based on the number of transmission opportunities Nt. In addition, the control unit 110 may also determine the size of the information related to unused opportunities based on the number of other parameters (e.g., (d3) or (d4)) associated with the row index "10". In addition, when the third table includes parameters (d5) and / or (d6) and / or (d7), the control unit 110 may also determine the size of the information related to unused opportunities based on the number of parameters (d5) and / or (d6) and / or (d7).

[0222] For example, the control unit 110 configures the size of the field for information related to unused opportunities included in the UCI to be 3 bits. That is, the control unit 110 generates the information related to unused opportunities in a size of 3 bits. That is, the control unit 110 may also determine the size of the information related to unused opportunities to be the same as the number of transmission opportunities Nt. Here, the control unit 110 may also determine the size of the information related to unused opportunities to be the same as the number of transmission opportunities Nt-1. As described above, the information related to unused opportunities is transmitted at the transmission opportunity of the uplink. Therefore, the uplink transmission opportunity used to transmit the information related to unused opportunities may also be excluded from the size of the information related to unused opportunities. For example, the control unit 110 may also identify the number of transmission opportunities Nt and determine the number obtained by subtracting 1 from the number of transmission opportunities Nt (for example, the number obtained by subtracting an equivalent number of uplink transmission opportunities used to transmit the information related to unused opportunities) as the size of the information related to unused opportunities. As described above, the control unit 110 may also determine the size of the information related to the unused opportunity based on the product value of the number of transmission opportunities Nt-1 and the number of time periods Np. The communication unit 120 transmits the UCI including the above fields to the base station device 20 (S1503).

[0223] Furthermore, the control unit 210 of the base station device 20 determines the size of the information related to unused opportunities based on the third table information and the information indicating the row index m. Specifically, the control unit 210 determines that the size of the field for the information related to unused opportunities included in the UCI is 3 bits. This allows the control unit 210 to determine the size of the field for the information related to unused opportunities included in the UCI before receiving the UCI from the terminal device 10.

[0224] The following describes in detail how to send UCI. Figure 17Examples include a first time period P1 and a second time period P2. Three transmission opportunities are configured for each of the first time period P1 and the second time period P2. The control unit 110 determines that the first transmission opportunity and the second transmission opportunity are used for uplink transmission in the first time period P1. The control unit 110 generates a 3-bit sequence {110}. The first to third values ​​of the sequence correspond to the first to third transmission opportunities, respectively. That is, the bits of information related to unused opportunities can also correspond to the ascending order of uplink transmission opportunities in ascending order. The value "0" can also indicate that the transmission opportunity is not used in uplink transmission. The value "1" can also indicate that the transmission opportunity is used in uplink transmission. The communication unit 120 can also send UCI including the above sequence to the base station device 20 at the first transmission opportunity in the first time period P1. That is, information related to unused opportunities in a certain time period can also indicate whether the transmission opportunities in the certain time period are used and / or not used. For example, the terminal device 10 can also indicate whether the transmission opportunities in the certain time period are used and / or not used by transmitting information related to unused opportunities in the certain time period.

[0225] Here, the information related to the unused opportunity may also indicate whether a transmission opportunity in a certain time period after the information related to the unused opportunity is transmitted is used and / or not used. For example, the terminal device 10 may also indicate whether a transmission opportunity in a time period after the information related to the unused opportunity is transmitted is used and / or not used by transmitting the information related to the unused opportunity. For example, the terminal device 10 may also indicate whether a transmission opportunity in a time period following the time period after the information related to the unused opportunity is transmitted is used and / or not used by transmitting the information related to the unused opportunity in a certain time period.

[0226] For example, when the terminal device 10 is configured with an indication of the transmission of information related to unused opportunities, it may also always send information related to unused opportunities (for example, bits of information related to unused opportunities) at the first transmission opportunity in one time period. For example, the terminal device 10 may also determine the number of modulation symbols (also called coded modulation symbols) for bits of information related to unused opportunities. In addition, the terminal device 10 may also determine the number of modulation symbols for bits of information for UL-SCH (i.e., uplink data). For example, the terminal device 10 may also send information related to unused opportunities and UL-SCH information together in PUSCH at the first transmission opportunity by linking the modulation symbols for bits of information related to unused opportunities with the modulation symbols for bits of information for UL-SCH. Here, in linking the modulation symbols, the modulation symbols for bits of information related to unused opportunities may be linked first, and then the modulation symbols for bits of information for UL-SCH may be linked. By this means, when mapping modulation symbols for the concatenated information to scheduled PUSCH resources, it is possible to avoid discarding modulation symbols for bits of information related to unused timings.

[0227] In addition, the terminal device 10 may send information related to unused opportunities without accompanying UL-SCH information when it does not have UL-SCH information (that is, there is no UL-SCH information). For example, the terminal device 10 may use the resources of PUSCH under the first transmission opportunity to send information related to unused opportunities without accompanying UL-SCH information when it does not have UL-SCH information. That is, the terminal device 10 may send information related to unused opportunities and UL-SCH information together when it has UL-SCH information (no UL-SCH information), and send information related to unused opportunities without accompanying UL-SCH information when it does not have UL-SCH information. For example, in the case of configuring an indication of the transmission of information related to unused opportunities, a field for information related to unused opportunities may always be ensured in the resources of PUSCH under the first transmission opportunity. In addition, the terminal device 10 may not send information related to unused opportunities when it does not have UL-SCH information. For example, when the terminal device 10 does not have the UL-SCH information, it can also skip (or give up) the transmission of information related to the unused timing in the first transmission timing.

[0228] Furthermore, the terminal device 10 may also transmit information related to unused opportunities when it has UL-SCH information. For example, the terminal device 10 may always transmit information related to unused opportunities along with UL-SCH information. For example, when the terminal device 10 does not have UL-SCH information at a first transmission opportunity but has UL-SCH information at a second transmission opportunity, it may also transmit information related to unused opportunities along with UL-SCH information at the second transmission opportunity.

[0229] In addition, information related to unused opportunities may also be sent together with the information of the UL-SCH corresponding to the redundant version number "0". For example, the terminal device 10 may also send information related to unused opportunities only when the redundant version number corresponding to the UL-SCH information to be sent is "0". For example, when the terminal device 10 does not have UL-SCH information at the first transmission opportunity and has UL-SCH information at the second transmission opportunity, it may also send the UL-SCH information corresponding to the redundant version number "0" at the second transmission opportunity. For example, information related to unused opportunities may also be sent together with the information of the UL-SCH corresponding to the redundant version number "0" sent at the second transmission opportunity.

[0230] In addition, the terminal device 10 may also send information indicating that information related to unused opportunities is sent (or, information related to unused opportunities is included (or, mapped or multiplexed) into PUSCH). The information indicating that information related to unused opportunities is sent may also include information indicating that information related to unused opportunities exists in PUSCH. The terminal device 10 may also connect the bits of information indicating that information related to unused opportunities is sent and the bits of information related to unused opportunities, and determine the number of modulation symbols for the bits of the connected information. For example, in the concatenation of information bits, the bits of information indicating that information related to unused opportunities is sent may be concatenated first, and then the bits of information related to unused opportunities are concatenated. By first identifying the information indicating that information related to unused opportunities is sent, the base station device 20 can identify the situation where information related to unused opportunities is included in the resources of PUSCH, and can decode the subsequent information related to unused opportunities. In addition, as described above, the terminal device 10 may also send information indicating the number of the redundant version (for example, information indicating the redundant version number "0"). For example, the terminal device 10 may also concatenate bits of information indicating the redundant version number and bits of information related to unused opportunities, and determine the number of modulation symbols for the concatenated bits of information. For example, in concatenating information bits, bits of information indicating the transmission of information indicating the redundant version number may be concatenated first, followed by bits of information related to unused opportunities. By first identifying information indicating the redundant version number (for example, information indicating the redundant version number "0"), the base station device 20 can identify a situation in which information related to unused opportunities is included in the PUSCH resources, and can decode subsequent information related to unused opportunities.

[0231] Here, using the transmission opportunity in uplink transmission can also be expressed as: it can also be used in uplink transmission, it can also be used in the terminal device 10, and / or it is a valid uplink resource. In addition, using the transmission opportunity in uplink transmission can also be expressed as: having a transmission opportunity (and / or a valid uplink resource) for uplink transmission (i.e., transmission of PUSCH), and / or considering that an uplink authorization is generated. Not using the transmission opportunity in uplink transmission can also be expressed as: it can also not be used in uplink transmission, it can also not be used in the terminal device 10, and / or it is an invalid (i.e., not valid) uplink resource. In addition, not using the transmission opportunity in uplink transmission can also be expressed as: not having a transmission opportunity for uplink transmission (i.e., transmission of PUSCH) (for example, releasing or discarding or ignoring the uplink resource), and / or not considering that an uplink authorization is generated (i.e., considering that an uplink authorization is not generated). In the above example, the value "0" corresponds to a value indicating that the transmission opportunity is not used in uplink transmission, and the value "1" corresponds to a value indicating that the transmission opportunity is used in uplink transmission. However, this is not limited to this example. Alternatively, the value "1" may correspond to a value indicating that the transmission opportunity is not used in uplink transmission, and the value "0" may correspond to a value indicating that the transmission opportunity is used in uplink transmission.

[0232] In addition, as described above, for example, the terminal device 10 may also store the RRC message and / or DCI from the base station device 20 as a configuration uplink grant in the MAC layer (i.e., the MAC layer in the terminal device 10), and consider that the uplink grant is generated in sequence, thereby performing the transmission of the PUSCH. In addition, the terminal device 10 may also include the UCI including information related to the unused timing into the PUSCH in the physical layer (i.e., the physical layer in the terminal device 10) (or, the UCI including information related to the unused timing may be mapped or multiplexed into the PUSCH). That is, the MAC layer in the terminal device 10 may also provide information related to the processing of the uplink grant to the physical layer in the terminal device 10. For example, the MAC layer may also provide information indicating that the uplink grant is considered to be generated (and / or, indicating that it is not considered to be generated) to the physical layer. For example, the MAC layer may also provide information indicating that the uplink grant is considered to be generated (and / or, indicating that it is not considered to be generated) to the physical layer based on the start and / or end of one time period of the CG. In addition, the MAC layer in the terminal device 10 may also provide information related to the information of UL-SCH to the physical layer in the terminal device 10. For example, the MAC layer may also provide information indicating that the UL-SCH is owned (or that the UL-SCH exists or is generated) and / or information indicating that the UL-SCH is not owned (or that the UL-SCH is not available or is not generated) to the physical layer. For example, the MAC layer may also provide information related to the information of UL-SCH to the physical layer based on the start and / or end of one time period of the CG. That is, the transmission timing used (or not used) in the uplink transmission may also be determined in the MAC layer in the terminal device 10. In addition, the physical layer in the terminal device 10 may also provide information indicating that the transmission timing is used (or not used) in the uplink transmission to the MAC layer. For example, the physical layer may also provide information related to unused timing to the MAC layer. For example, the physical layer may also provide information indicating that the transmission timing is used (or not used) in the uplink transmission to the MAC layer based on the start and / or end of one time period of the CG. That is, the transmission timing to be used (or not used) in uplink transmission may also be determined in the physical layer in the terminal device 10 .

[0233] Similarly, control unit 110 determines that all transmission opportunities from the first to the third in second period P2 will be used for uplink transmission. Control unit 110 generates a three-bit sequence {111}. Communication unit 120 may also transmit UCI including the above sequence to base station device 20 during the first transmission opportunity in second period P2.

[0234] In addition, in type 1, the third table information may also be included in the parameters related to the CG. That is, the third table information may also be included in the RRC message of step S1502. The third table information may also be included in the ConfiguredGrantConfigIE.

[0235] —Type 2

[0236] The same actions as those described in the description of type 1 can also be applied to type 2. Figure 18 As shown, the communication unit 220 of the base station device 20 sends an RRC message including parameters related to PUSCH to the terminal device 10 (S1801). The parameters related to PUSCH include third table information. The parameters related to PUSCH may also be PUSCH-ConfigIE. The third table information may also be included in PUSCH-ConfigIE. In addition, the third table information may also be included in IEs other than PUSCH-ConfigIE. The third table information may also be included in parameters related to CG. For example, the third table information may also be included in ConfiguredGrantConfigIE.

[0237] The control unit 110 of the terminal device 10 configures the third table based on the third table information. In addition, the terminal device 10 may also perform PUSCH transmission (i.e., type 2 CG PUSCH transmission) based on the third table information. The third table information includes at least one of the parameters (d1) to (d7). The control unit 110 configures Figure 16 The third table shown.

[0238] The communication unit 220 of the base station device 20 sends the DCI to which the CRC encrypted by the CS-RNTI is added to the terminal device 10 (S1802). Thereby, the periodic transmission action of the terminal device 10 using the PUSCH is activated. Furthermore, the DCI includes information indicating a row index m for referencing the third table. The information indicating the row index m may be included in the TDRA field in the DCI. The size of the TDRA field (i.e., the number of bits or the bit width) may also be determined based on the number of entries of the third table (i.e., the number of parameters (or parameter sets) included (or recorded in the entries) in the third table information).

[0239] Assume that the information indicating row index m for referencing the third table indicates "9." Control unit 110 refers to row index m+1 of the third table. Control unit 110 obtains three parameter sets corresponding to three transmission opportunities, associated with row index "10" of the third table. Control unit 110 uses these three parameter sets to determine the resources for each uplink transmission.

[0240] In addition, the control unit 110 determines the size of the information related to the unused opportunity based on the number of parameters associated with the row index "10" as in the case of Type 1 described above. Specifically, the control unit 110 determines (or determines) that the number of transmission opportunities Nt is "3" based on the number of parameters associated with the row index "10". The control unit 110 determines the size of the information related to the unused opportunity based on the number of transmission opportunities Nt. In addition, the control unit 110 may also determine the size of the information related to the unused opportunity based on the number of transmission opportunities Nt-1. In addition, the control unit 110 may also determine the size of the information related to the unused opportunity based on the product value of the number of transmission opportunities Nt and the number of time periods Np. In addition, the control unit 110 may also determine the size of the information related to the unused opportunity based on the product value of the number of transmission opportunities Nt-1 and the number of time periods Np.

[0241] For example, the control unit 110 configures the size of the field for information related to unused opportunities included in the UCI to 3 bits. That is, the control unit 110 generates information related to unused opportunities in a size of 3 bits. The communication unit 120 transmits the UCI including the above-mentioned field to the base station device 20 (S1803). In addition, the communication unit 120 may also Figure 17 As described in , UCI is sent to the base station device 20.

[0242] Furthermore, the control unit 210 of the base station device 20 determines the size of the information related to unused opportunities based on the third table information and the information indicating the row index m. Specifically, the control unit 210 determines that the size of the field for the information related to unused opportunities included in the UCI is 3 bits. This allows the control unit 210 to determine the size of the field for the information related to unused opportunities included in the UCI before receiving the UCI from the terminal device 10.

[0243] According to the above configuration, the terminal device 10 is able to appropriately determine the size of the information related to the unused opportunity based on the third table information and the indication information (ie, the information indicating the row index m).

[0244] Furthermore, base station device 20 is able to appropriately discern the size of information related to unused opportunities based on the third table information and the indication information (i.e., information indicating row index m). Therefore, base station device 20 is able to appropriately receive UCI including information related to unused opportunities. Upon receiving information related to unused opportunities from terminal device 10, base station device 20 is able to allocate the unused opportunities to terminal devices other than terminal device 10. With this configuration, base station device 20 is able to efficiently allocate wireless resources to multiple terminal devices.

[0245] The configuration of the third table is not limited to Figure 16 For example. Figure 19 As shown, the parameter (d1) may be configured separately for each of the three transmission opportunities. In this case, the control unit 110 may determine the size of the information related to the unused opportunities based on the number of parameters (d1) associated with the row index.

[0246] The arrangement of information related to unused timing is not limited to Figure 17 For example. The information related to the unused opportunity may also indicate the number of transmission opportunities to be used. The number of transmission opportunities to be used may also indicate the number of consecutive transmission opportunities. For example, the transmission opportunity after the transmission opportunity indicated by the number of transmission opportunities may not be used for uplink transmission. Figure 14 In the example, 3 transmission opportunities are configured in 1 time period, so the information related to the unused opportunity can be a 2-bit sequence that can express 0 to 3. As described above, it is assumed that "9" is represented by the information representing the row index m for referencing the third table. In this case, the terminal device 10 can determine that the size of the information related to the unused opportunity is 2 bits based on the number of parameters associated with the row index "10" of the third table (i.e., 3). Therefore, the terminal device 10 can also generate a 2-bit sequence as the information related to the unused opportunity. That is, the control unit 110 can also use the number of transmission opportunities Nt to determine the size of the field related to the unused opportunity included in the UCI as ceil(log2(Nt)). Here, the control unit 110 can also determine the size of the information related to the unused opportunity as ceil(log2(Nt-1)). In addition, the control unit 110 can also determine the size of the information related to the unused opportunity based on the product value of ceil(log2(Nt)) and the number of time periods Np. The control unit 110 may determine the size of the information related to the unused opportunity based on the product value of ceil(log2(Nt−1)) and the number of time slots Np.

[0247] like Figure 20As shown, the control unit 110 determines to use the first transmission opportunity and the second transmission opportunity for uplink transmission in the first time period P1. Because the number of transmission opportunities to be used is "2", the control unit 110 can also generate a 2-bit sequence {10} corresponding to the value "2". The communication unit 120 can also send the UCI including the above sequence to the base station device 20 at the first transmission opportunity in the first time period P1. That is, the communication unit 120 can also indicate the use and / or non-use of the transmission opportunity in a certain time period by transmitting information related to the unused opportunity in the certain time period. Here, the communication unit 120 can also indicate the use and / or non-use of the transmission opportunity in one time period after the transmission of the information related to the unused opportunity by transmitting information related to the unused opportunity. For example, the communication unit 120 can also indicate the use and / or non-use of the transmission opportunity in the next time period of the certain time period by transmitting information related to the unused opportunity in the certain time period.

[0248] Similarly, control unit 110 determines to use all of the first through third transmission opportunities for uplink transmission in second period P2. Because the number of transmission opportunities to be used is "3," control unit 110 may also generate a two-bit sequence {11} corresponding to the value "3." Communication unit 120 may also transmit UCI including the above sequence to base station device 20 during the first transmission opportunity in second period P2.

[0249] The third table may also be a table related to uplink transmission resources in the DG. For example, the third table may be the second table described above. The control unit 110 may also use the table related to uplink transmission resources in the DG to determine the resources of multiple transmission opportunities included in one time period in the CG. The control unit 110 may also use the second table to determine the size of the information related to unused opportunities using the same method as described above.

[0250] The control unit 110 may also switch between the first table and the third table according to the configuration information. It can be said that the first table is the table used when one time period includes one transmission opportunity, and the third table is the table used when one time period includes multiple transmission opportunities. For example, when the terminal device 10 receives both the third table information and information indicating the row index m from the base station device 20, the control unit 110 may also use the third table. That is, the control unit 110 uses the third table to determine the resources of the multiple transmission opportunities included in one time period. Furthermore, the control unit 110 uses the third table to determine the size of the information related to unused opportunities.

[0251] On the other hand, if the terminal device 10 does not receive at least one of the third table information and the information indicating the row index m from the base station device 20, the control unit 110 may also use the first table. That is, the control unit 110 uses the first table (that is, the parameters (or parameter sets) included in the first table) to determine the resources for uplink transmission.

[0252] When the second table is used as the third table as described above, the control unit 110 may also switch between the first table and the second table according to the configuration information. When the terminal device 10 receives both the second table information and the information indicating the row index m from the base station device 20, the control unit 110 may also use the second table. That is, the control unit 110 uses the second table (i.e., the parameters (or parameter sets) included in the second table) to determine the resources of the multiple transmission opportunities included in a time period. Furthermore, the control unit 110 uses the second table to determine the size of the information related to the unused opportunities.

[0253] On the other hand, if the terminal device 10 does not receive at least one of the second table information and the information indicating the row index m from the base station device 20, the control unit 110 may also use the first table. That is, the control unit 110 uses the first table (that is, the parameters (or parameter sets) included in the first table) to determine the resources for uplink transmission.

[0254] (2) Second Option

[0255] The configuration information may also include first information related to the number of repetitions of uplink transmission (i.e., transmission of PUSCH). For example, the first information may also be included in a parameter related to the CG included in the RRC message. For example, the first information may also be included in the ConfiguredGrantConfig IE. The first information may also be repK included in the ConfiguredGrantConfigIE. repK indicates the number of repetitions applied to the transmitted TB with respect to the PUSCH transmission implemented by the CG. repK may also indicate the number Nt of multiple transmission opportunities included in one time period. In this configuration, the control unit 110 determines the size of the information related to the unused opportunity based on the value of repK.

[0256] The configuration information may also include second information related to the number Nt of multiple transmission opportunities. For example, the second information may also be included in the parameters related to the CG included in the RRC message. The IE corresponding to the second information may also be redefined as ConfiguredGrantConfig IE. In this configuration, the control unit 110 determines the size of the information related to the unused opportunity based on the second information. In addition, as described above, the control unit 110 may also determine the size of the information related to the unused opportunity by excluding the transmission opportunity of the uplink used to send the information related to the unused opportunity. For example, the control unit 110 may also determine the number obtained by subtracting 1 from the number of transmission opportunities Nt represented by the second information as the size of the information related to the unused opportunity. In addition, the control unit 110 may also determine the size of the information related to the unused opportunity based on the second information and the number of time periods Np (or, information representing the number of time periods Np) (for example, based on the product value of the number of transmission opportunities Nt and the number of time periods Np). In addition, the control unit 110 can also determine the size of the information related to the unused opportunities based on the number of transmission opportunities Nt-1 and the number of time periods Np represented by the second information (for example, based on the product value of the number of transmission opportunities Nt-1 and the number of time periods Np).

[0257] According to the above-described configuration, the terminal device 10 can appropriately determine the size of the information related to the unused opportunity based on the first information or the second information.

[0258] Similarly, the control unit 210 of the base station device 20 determines the size of the information related to unused opportunities based on the first information or the second information. This allows the base station device 20 to determine the size of the field containing the information related to unused opportunities, including UCI, before receiving the UCI from the terminal device 10. Consequently, the base station device 20 can appropriately receive UCI including the information related to unused opportunities.

[0259] (3) The third option

[0260] The configuration information may also include at least one of third information related to the number of transmission opportunities for uplink transmission included in 1 time slot and fourth information related to the number of time slots included in a periodicity configured in the CG.

[0261] The third information may also be included in the CG-related parameters included in the RRC message. For example, the third information may also be included in the ConfiguredGrantConfig IE. The third information may also be cg-nrofPUSCH-InSlot included in the ConfiguredGrantConfig IE. cg-nrofPUSCH-InSlot indicates the number of consecutive PUSCH transmission opportunities within one time slot.

[0262] The fourth information may also be included in the CG-related parameters included in the RRC message. For example, the fourth information may also be included in the ConfiguredGrantConfig IE. The fourth information may also be cg-nrofSlots included in the ConfiguredGrantConfig IE. cg-nrofSlots indicates the number of consecutive time slots allocated within the period configured in the CG.

[0263] In the past, when multiple transmission opportunities were configured in the CG of the unlicensed spectrum channel, the above-mentioned cg-nrofPUSCH-InSlot and cg-nrofSlots were used. The above-mentioned cg-nrofPUSCH-InSlot and cg-nrofSlots can also be applied when multiple transmission opportunities are configured in one time period in the CG.

[0264] The control unit 110 determines the number Nt of transmission opportunities included in one time slot based on one or both of the third information and the fourth information. The control unit 110 then determines the size of the information related to unused opportunities based on the number Nt of transmission opportunities. Alternatively, the control unit 110 may determine the size of the information related to unused opportunities by subtracting 1 from the number Nt of transmission opportunities indicated by one or both of the third information and the fourth information as the number of information related to unused opportunities. Alternatively, the control unit 110 may determine the size of the information related to unused opportunities based on one or both of the third information and the fourth information and the number Np of time slots (or information indicating the number Np of time slots) (e.g., based on the product of the number Nt of transmission opportunities and the number Np of time slots). Alternatively, the control unit 110 may determine the size of the information related to unused opportunities based on the number Nt-1 of transmission opportunities and the number Np of time slots indicated by one or both of the third information and the fourth information (e.g., based on the product of the number Nt-1 of transmission opportunities and the number Np of time slots).

[0265] According to the above-described configuration, the terminal device 10 is able to appropriately determine the size of the information related to the unused opportunity based on one or both of the third information and the fourth information.

[0266] Similarly, the control unit 210 of the base station device 20 determines the size of the information related to unused opportunities based on one or both of the third information and the fourth information. This allows the control unit 210 to determine the size of the field containing the information related to unused opportunities, including UCI, before receiving the UCI from the terminal device 10. Consequently, the base station device 20 can appropriately receive UCI including the information related to unused opportunities.

[0267] (4) The fourth option

[0268] The configuration information may also include fifth information related to an offset for determining the position of a time slot and / or symbol of a transmission opportunity in the CG. That is, the fifth information may also be used to determine the position of a time slot and / or symbol for each of one or more transmission opportunities in a time period. The fifth information may also be used to determine the position of one or more uplink transmissions (i.e., PUSCH transmissions) in a time period.

[0269] The fifth information may also be included in the CG-related parameters included in the RRC message. For example, the fifth information may also be included in the ConfiguredGrantConfig IE. The fifth information may also be the timeDomainOffset included in the ConfiguredGrantConfig IE. The timeDomainOffset is a parameter used in a predetermined formula for determining the position of the time slot and / or symbol of the transmission opportunity in the CG. In the ConfiguredGrantConfig IE, multiple timeDomainOffsets may also be configured as the fifth information. When multiple timeDomainOffsets are configured, this may also mean that multiple transmission opportunities are configured in one time period. For example, the base station device 20 may also send an RRC message including a list of one or more timeDomainOffsets. For example, the multiple timeDomainOffsets included in the list may also correspond to the ascending order of the multiple transmission opportunities in ascending order. That is, the first timeDomainOffset included in the list may correspond to the first transmission opportunity in one time period, the second timeDomainOffset included in the list may correspond to the second transmission opportunity in one time period, and the third timeDomainOffset included in the list may correspond to the third transmission opportunity in one time period.

[0270] The control unit 110 determines (or determines) the number of transmission opportunities Nt based on the number of timeDomainOffsets. Then, the control unit 110 determines the size of the information related to the unused opportunities based on the number of transmission opportunities Nt. In addition, the control unit 110 may also determine the size of the information related to the unused opportunities by subtracting 1 from the number of transmission opportunities Nt represented by the number of timeDomainOffsets as the number of information related to the unused opportunities. In addition, the control unit 110 may also determine the size of the information related to the unused opportunities based on the number of timeDomainOffsets and the number of time periods Np (or information representing the number of time periods Np) (for example, based on the product value of the number of transmission opportunities Nt and the number of time periods Np). In addition, the control unit 110 may also determine the size of the information related to the unused opportunities based on the number of transmission opportunities Nt-1 represented by the number of timeDomainOffsets and the number of time periods Np (for example, based on the product value of the number of transmission opportunities Nt-1 and the number of time periods Np).

[0271] According to the above-described configuration, the terminal device 10 is able to appropriately determine the size of the information related to the non-used opportunities based on the fifth information.

[0272] Similarly, the control unit 210 of the base station device 20 determines the size of the information related to unused opportunities based on the fifth information. This allows the control unit 210 to determine the size of the field containing the information related to unused opportunities in the UCI before receiving the UCI from the terminal device 10. Consequently, the base station device 20 can appropriately receive the UCI containing the information related to unused opportunities.

[0273] In the first to fourth schemes, the UCI including information related to the unused opportunity can be either CG-UCI or other UCI. The CG-UCI including information related to the unused opportunity can be used in an unlicensed spectrum channel or in a licensed spectrum channel.

[0274] In an unlicensed spectrum channel, the CG-UCI including information related to unused opportunities may also include at least one of the fields (c1) to (c5) described above. That is, the CG-UCI may include a field for information related to unused opportunities in addition to at least one of the fields (c1) to (c5). When a CG-UCI including information related to unused opportunities is used in a licensed spectrum channel, the CG-UCI may also not include at least one of the fields (c1) to (c5).

[0275] When CG-UCI is used to transmit information related to unused opportunities, the multiplexing scheme described in Reference 2 may also be used. For example, the multiplexing scheme described in Reference 2 may also be used to multiplex CG-UCI including information related to unused opportunities with user data.
